Int. Cl. B65d 7/42 US. Cl. 220--68 7 Claims ABSTRACT OF THE DISCLOSURE The present invention is directed to a desk drawer comprising a bottom wall and a pair of longitudinal side walls extending upwardly from the side edges thereof, an outer front wall, closing the front area, a rearwardly and downwardly directed retaining flange on the upper edge of the outer front wall, an inner front wall disposed between the side walls extending from the bottom wall upwardly into the retaining flange, an upstanding projection struck from the bottom wall retaining the lower end of the inner front wall in fixed relation to the outer front wall.

This application is a division of the copending application, Ser. No. 503,157, filed Oct. 23, 1965, for Desk Construction, now Patent No. 3,363,955.

This invention relate to furniture constructions, and particularly to drawer constructions for desks and the like.

An important object of the invention is to provide an improved drawer construction wherein the sidewalls of the drawers are formed of double thickness, the outer thickness of the side wall being shaped to provide integral support flanges for engagement with the supporting glides and an integral retaining flange to cooperate with the glides to control the side movement of the drawer.

Yet another object of the invention is to provide an improved furniture drawer for use in desks and the like, the drawer having a double wall head including an outer wall having a U-shaped retaining flange at the upper end thereof and an inner wall having the upper end thereof retained within the U-shaped retaining flange and having the lower end thereof held in the operative position thereof by a projection upstanding from the bottom wall of the drawer.

In connection with the foregoing object, it is another object of the invention to provide a drawer head structure wherein the inner wall is corrugated or ribbed and is held in place fundamentally by a spring effect, and further including an adhesive bonding between the outer wall and the inner wall at the upper portion thereof, thereby to eliminate the need for a filler therebetween.

Still another object of the invention is to provide in a furniture drawer of the type set forth, an improved compressor plate construction and specifically an improved compressor bracket therefor molded or lubric material and being constructed and arranged to provide for self-locking upon release thereof due to the downward force of gravity and a rearward force resulting from the pressure of material lying between the front of the drawer and the compressor plate.

Further features of the invention pertain to the particular arrangement of the parts whereby the above-outlined and additional features thereof are attained.

Referring now to the drawings, and particularly to FIGS. 1 to 4 thereof, there is illustrated a piece of furniture made in accordance with and embodying the principles of the present invention, a lefthand single pedestal desk 100 having been shown for purposes of illustration. The desk 100 includes a desk top 101 at one end of which is disposed a pedestal 150 supported by a pair of legs 500 having associated feet 520, the pedestal 150 having mounted therein a shelf 190, a box drawer 210 and a file drawer 270, the shelf 190 being provided with a pull 1901, the box drawer 210 being provided with a pull 2101 and the file drawer 270 being provided with a pull 270P. Mounted on the other end of the desk top 101 is an end panel 450 supported by a pair of legs 550 having associated feet 570, the space between the pedestal 150 and the end panel 450 at the rear of the desk top 101 being closed by a back panel 400; as may be best seen in FIG. 3, the back panel 400 is provided with a pair of wiring openings 415 for the reception of telephone wires and the like. There further is mounted on the desk top 101 a center drawer 380 and a depending front wall or skirt 390, a lock 360 being provided in substantially the center of the front edge of the desk top 101 to lock the several drawers 210, 270 and 380.

The desk top 101 more specifically includes an edging 103 extending around the periphery thereof and formed of sheet metal and generally extending downwardly and inwardly. The desk top 101 further carries a decorative trim 130 also extending around the periphery thereof. The pedestal 150 has a rectangular rear wall 152 and a pair of substantially parallel side walls 153 extending forwardly therefrom and disposed substantially perpendicular thereto and parallel to each other, the corners between the rear wall 152 and the side walls 153 being rounded. The forward edges of the side flanges 153 carry inwardly curved front flanges 159 that extend substantially vertically and terminate in rearwardly directed flanges 159a. Disposed in the forward portion of the pedestal 150 is a front frame 160 formed of two substantially C-shaped channels which in turn are essentially U-shaped in cross section, each including a main wall 162 and a pair of integral side flanges 1-63 extending normal thereto and parallel to each other. The free ends of the C-shaped channels disposed toward each other are joined by a splice channel 164 placed in bridging relationship therewith. Finally, there is provided on the side walls 153 internally of the pedestal 150 but disposed-forwardly toward the front frame 160 a pair of drawer supports 180 each including a main wall 182 and having on the vertically extending edges thereof side walls that extend outwardly toward the associated pedestal side wall 153.

As is illustrated in FIGS. 1 and 2, the pedestal 150 has mounted therein a shelf 190, a box drawer 210 and a file drawer 270. By reference to FIGS. 8, 9 and 11 to 13, the details of construction of the shelf 190 and the mount ing thereof in the pedestal 150 will be described. The shelf 190 includes a top 191 having a width slightly less than the width of the interior of the pedestal 150 and a length slightly less than the length of the pedestal 150 (see FIG. 9), the longitudinally extending edges of the top 191 having depending side walls 192 disposed respectively thereon and carrying on the lower edges thereof inwardly directed support flanges 193 terminating in rounded and outturned flanges 194 (see FIG. 11). The rear of the shelf 190 is provided with a back Wall 195 and formed on the rear of the side walls 192 are inturned reinforcement flanges 196 disposed against the inner side of the back wall 195 and suitably secured thereto as by welding. The forward end of the top 191 carries a downwardly directed front wall 197 (see FIG. 9) that carries on the lower edge thereof a rearwardly directed L-shaped flange 198. The shelf 190 carries two pairs of bumpers 199, namely, a rear pair of bumpers 199 each having a mounting stud 199a extending through an opening in the rear flange 195 and a front pair of bumpers 199 each having a mounting stud 199a extending through an opening in the L-shaped flange 198.

The shelf 190 is mounted upon two pairs of shelf glides 200 that are substantially identical in construction but are formed as mirror images of each other, the construction of one of the shelf glides 200 being best illustrated in FIGS. 11 to 13 of the drawings. Each shelf glide 200 includes a body 201 that is essentially block shaped and has on the outwardly disposed wall thereof a pair of longitudinally spaced apart positioning studs 202 for assisting in mounting the shelf glide upon the associated support structure; more specifically, the forward ones of the shelf glides 200 are mounted upon the front frame 160, the positioning studs 202 extending through suitably disposed openings in the main wall 162, and the rearward ones of the shelf glides 200 are mounted upon the drawer supports 180, the positioning studs 202 extending through suitably disposed openings in the main walls 181. There further is provided an opening 203 through each of the bodies 201 to receive a bolt 204 extending therethrough and engaging an associated threaded opening in the associated main wall 162 or 181 as the case may be, thereby firmly to mount the associated shelf glide 200 thereon. Each of the glide bodies 201 includes a lower surface 205 on which rests the associated supporting flange 193 of the shelf 190, the support surface 205 extending outwardly to the associated main wall 162 or 181, as the case may be, and extending inwardly and terminating at an upstanding wall 206 integral with the body 201, the upper end of the Wall 206 carrying a top flange 206a. The wall 206 includes an outwardly disposed surface 207 and the flange 206a has an upper support surface 208 thereon. When the shelf 190 is in the storage position thereof illustrated in FIG. 9, the major portion thereof is disposed rear wardly or to the right with respect to the support and therefor rearwardly or to the right of the rearmost shelf glides 200, whereby the support flange 193 engages the lower support surface 205 on the rear glides 200 and serves as a fulcrum for pivoting the portion of the shelf in front of or to the left of the support 180 upwardly, whereby the upper surface of the flange 194 engages the upper support surfaces 208 of the shelf glides 200 mounted on the front frame 160. Conversely, when the shelf 190 is in the fully withdrawn or extended position, the support flanges 193 rest upon the associated lower support surfaces 205 of the glides 200 mounted on the front frame 160 and the flanges 194 abut against the upper support surfaces 208 on the shelf glides 200 mounted upon the supports 180. It further is pointed out that when the shelf 190 is in the full storage position illustrated in FIG. 9, the front bumpers 199 abut against the shelf glides 200 mounted on the front frame 160, and when the shelf 190 is in the fully extended or withdrawn position thereof, the rear bumpers 199 abut against and engage the shelf glides 200 mounted on the supports 180.

It is an important feature of the present invention to form the shelf glides 200 of a lubric material, the preferred lubric material being a synthetic organic plastic resin, the preferred resin being an acetal resin such as that sold under the trademark Delrin. The bumpers 199 may likewise be formed of such material, or may be formed of the usual elastomeric materials. In order to control the side movement of the shelf 190, a pair of buttons 209 is provided on the lefthand side as viewed in FIGS. 1, 2, 8 and 11, the buttons 209 being mounted upon the associated main walls 162 and 181, respectively, and including mounting studs 209a extending into suitable openings in the associated main wall. The buttons 289 are also preferably formed of the same lubric material as the shelf glides 200 and are dimensioned so that the inner surface thereof is disposed away from the surfaces 207 on the associated glides 200 a distance just slightly greater than the lateral distance between the outer surface of the shelf side wall 192 and the innermost point on the rounded outturned flange 194. By this construction, accurate yet easy control of the side motion of the shelf 190 is obtained during movement between the storage position thereof and the fully extended position thereof. The necessity of providing -a side rail on the interior of the pedestal has also been eliminated, :all while providing smooth and quiet mounting of the shelf 190 during all movement thereof.

The construction and mounting of the box drawer 210 is best illustrated in FIGS. 8, 9 and 14 to 20, inclusive. Referring first to FIGS. 8 and 14, the box drawer 210 includes a bottom wall 211 that is substantially rectangular in shape and has a width slightly less than the interior width of the pedestal 150 and has a length slightly less than the length of the pedestal 150 (see FIG. 9 also). Disposed on the longitudinally extending side edges of the bottom wall 211 are upstanding inner side walls 212, the side walls 212 being disposed substantially parallel to each other and normal to the bottom wall 211 and extending substantially the entire length thereof. Interconnecting the rear ends of the bottom wall 211 and the inner side walls 212 is a rear wall 213, all of the walls n amed being mutually interconnected. Each of the side walls 212 in addition includes an outer side wall generally designated by the numeral 214, each of the outer side walls 214 including a bottom flange 215, a lower support flange 216, a retaining flange 217, an upper sup port flange 218 and a connecting wall 219 disposed between the support flanges 216 and 218. It will be understood that a single piece of sheet metal is shaped to provide the various parts named, the bottom flange 215 lying beneath the bottom wall 211 and being secured thereto as by welding and the connecting wall 219 lying against the surface of the associated wall 212 and being secured thereto as by welding. The two support flanges 216 and 218 are disposed parallel to each other and normal to the drawer side wall and extend laterally outwardly with respect thereto; and the retaining flange 217 extends upwardly substantially normal to the support flanges 216 and 218 and is spaced outwardly a predetermined distance with respect to the connecting wall 219, the support flanges 216 and 218 and the retaining flange 217 extending substantially the entire length of the drawer 210. Extending upwardly from the upper support flange 218 is a connecting section 222 (see FIG. 8) on the upper end of which is an integral outstanding reinforcement section 223 and above which is another connecting sec tion 224 carrying 'an upper outstanding reinforcement section 226 that carries on the inner portion thereof a downturned flange 227 disposed adjacent to an outwardly offset flange 228 on the upper edge of the associated inner side wall 212. It will be understood that each of the portions and sections named is formed integral from the same piece of sheet metal as that from which are formed the other portions of the outer side wall 214. In the construction, the connecting sections 222 and 224 are disposed against the outer surface of the associated inner side wall 212 and are suitably secured thereto as by welding, whereas the reinforcement sections 223 and 226 are spaced outwardly with respect to "the inner side wall 212. In passing it is noted that both sides of the box drawer 210 have the double wall construction described, and in the interest of brevity, the construction of the other side of the drawer 210 will not be described, but like reference numerals are applied to like parts thereof.

The box drawer 210 is supported within the pedestal for movement between a stonage position and an extended position on four glides disposed 'between the support flanges 216 and 218 thereof. A first form of glide 230 is provided on the lefthand side of the drawer 210 as viewed in FIGS. 1, 2, 8 and 14, this form of glide 230 including a generally rectangular body 231 (see FIGS. 1'5 to 17 particularly). The glide body 231 has formed integral therewith a mounting shank 232 disposed on the one side of the body 231 and having integral therewith a positioning stud 233 extending laterally therefrom and into an associated opening in the main wall 162 or the main wall 181 of the from frame or the drawer support as the case may be. There also is formed in the body 231 an opening 234 that connects with a like opening in the shank 232 to receive therethrough .a bolt 235, the threaded shank of the bolt 235 engaging in a complementarily threaded opening in the associated wall 162 or 181, as the case may be, thereby in cooperation with the positioning stud 233 firmly to mount the associated glide 230 upon the pedestal 150. The glide body 231 has an upper support surface 236 which is substantially flat and .a lower support surface 237 which is also substantially flat. Provided on the upper and lower outer sides of the body 231 are outside guide walls 238, and provided on the upper and lower inner edges of the body 231 are inner side guide walls 239, the upper and lower guide walls 239 being separated by a recess 2390 in the inner surface of the body 231.

A second form of glide 240 is provided on the righthand side of the drawer 210 as viewed in FIGS. 1, 2, 8 .and 14, this form of glide 240 including a generally rectangular body 241 (see FIGS. 18 to 20 particularly). The glide body 241 has formed integral therewith a mounting shank 242 disposed on one side of the body 241 and having integral therewith a positioning stud 243 extending laterally therefrom and into an associated opening in the main wall 162 or the main wall 181 of the front frame 160 or the drawer support 180, as the case may be. There also is formed in the body 241 an opening 244 that connects with a like opening in the shank 242 to receive there-through a bolt 245, the threaded shank of the bolt 245 engaging in 'a complementarily threaded opening in the associated wall 162 or 181, as the case may be, thereby in cooperation with the positioning stud 243 firmly to mount the associated glide 240 upon the pedestal 150. The glide body 241 has an open support surface 246 which is substantially flat and a lower support surface 247 which is also substantially flat.

Referring to FIG. 9, it will be seen that the box drawer 210 in the storage position illustrated therein has the major portion thereof disposed rearwardly or to the right with respect to the drawer supports 180, whereby the portion of the drawer to the right of the drawer supports 180 is supported in cantilever fashion. As a result, the upper support flanges 218 rest upon and are supported by the upper surfaces 236 and 246, respectively, of the glides 230 and 240 mounted upon the drawer supports 180, but the lower support flanges 216 engage the lower support surfaces 237 and 247, respectively, on the glides 230 and 240 mounted upon the front frame 160. However, when the drawer 210 is moved to the fully extended position thereof, i.e., to the left as viewed in FIG. 9, the major portion thereof is supported in cantilever fashion outside of the pedestal 150, whereby the upper support flanges 218 thereof rest upon the upper surfaces 236 and 246, respectively, of the glides 230 and 240 mounted on the front frame 160, while the lower support flanges 216 thereon rest against the lower support surfaces 237 and 247, respectively, of the glides 230 and 240 mounted on the drawer supports 180. Side movement of the drawer 210 during movement between the storage and extended positions thereof is controlled by the cooperation between the retaining flange 217 and the outside guide wall 238 and between the connecting wall 219 and the inside guide walls 239, it being noted that the entire side guide function is performed by the glides 230, the glides 240 contributing not at all to the side guide function is performed by the glides 230, the glides 240 contributing not at all to the side guide function. Preferably both the glides 230 and the glides 240 are formed of a lubric material, the preferred material being a synthetic organic plastic resin, the preferred resin being an acetal resin such as that sold under the trademark Delrin, whereby smooth and quiet operation is obtained when moving the box drawer 210 between the storage and extended positions thereof.

The construction of the drawer head for the box drawer 210 is best illustrated in FIGS. 26 to 29, inclusive, wherein it will be seen that there is provided an outer front wall 250 that is generally rectangular in shape and extends outwardly beyond the side walls 212 and upwardly beyond the upper edges of the side walls 212 and downwardly as at 251 below the bottom wall 211. Disposed on the side edges of the front wall 250 are side flanges 259 (see FIG. 6) that extend rearwardly and carry on the rear edges thereof inturned flanges 259a. Disposed on the lower edge of the front wall 250 is a rearwardly directed flange 252 underlying and spaced from the undersurface of the bottom wall 211, the rear edge of the flange 252 carrying an upturned flange 253 extending upwardly to the undersurface of the bottom wall 211 and carrying thereon a rearwardly directed attachment flange 254 lying against the undersurface of the wall 211, means being provided suitably to secure as by welding the outer front wall 250 to the bottom wall 211 and the side walls 212. The upper end of the front wall 250 carries a U-shaped retaining flange 255 including a rearwardly and slightly downwardly directed portion 256 and a downwardly directed portion 257 disposed substantially parallel to and spaced from the front wall 250. Spaced from the lower end of the front wall 250 and struck from the bottom wall 211 are two upwardly extending projections 258.

Disposed behind the outer front wall 250 and within the drawer 210 is an inner front wall 260 that extends substantially between the side walls 212 and from the bottom wall 211 upwardly to the U-shaped retaining flange 255 on the front wall 250. The inner front wall 260 comprises a pair of reinforcing ribs 261 each including a forward portion 262 and a pair of connecting portions 263. At the upper end of the inner front wall 260 is a forwardly offset flange 264 that lies against the inner surface of the downwardly directed portion 257 and carrying on the upper end thereof a top Z flange 265 extending forwardly to the inner surface of the outer front wall 250 and in turn carrying a front flange 266 lying against the inner surface of the outer front wall 250. In the assembled condition illustrated in FIGS. 26 and 28, the lower end of the inner front wall 260 extends downwardly to the bottom wall 211 and is disposed forwardly with respect to the projections 258 and carries on the lower end thereof a forwardly directed bottom Z flange 267 that extends forwardly to the inner surface of the outer front wall 250 and in turn carries thereon a downwardly extending front flange 268 that lies against the inner surface of the outer front wall 250. Finally, bodies of mastic 269 are provided between the U-shaped retaining flange 255 and the upper end of the inner front wall 260, between the ribs 261 and the front wall 250 and between the Z flange 267 and the outer front wall 259, further to interconnect the front walls 250-260 and to provide a sound deadening effect therebetween. The bodies of mastic 269 are preferably formed of a heat curing mastic sold under the trademark Presstite No. 719.

The assembly of the inner front wall 260 with respect to the outer front wall 250 is diagrammatically illustrated in FIG. 27. Prior to assembly of the parts, the bodies of 8 mastic 269 are respectively placed upon the upper portion of the inner front wall 260, upon the ribs 261 and the Z flange 267, after which the upper end of the inner front wall 260 is pushed into the U-shaped retaining flange 255 as is diagrammatically illustrated in FIG. 27. The proportions among the parts is such that the upper end of the inner front wall 260 may be moved upwardly into the U-shaped retaining flange 255 a distance greater than the vertical extent thereof thereinto in the fully assembled position, whereby in combination with the springlike character of the inner front wall 260 imparted thereto by the material of construction, namely, sheet metal, and the provision of the ribs 261, permits the lower end of the inner front wall 260 to pass above the projections 258. Having passed the projections 258 and with the front flange 268 against the inner surface of the outer front wall 250, the entire inner front wall 260 can then be moved downwardly to seat the lower end thereof between the outer front wall 250 and the projections 258 as is diagrammatically illustrated in FIG. 28. Gravity and the bodies of mastic 269 serve to hold the parts in this position.

Disposed lowermost in the pedestal is the file drawer 270, the details of construction and the mounting thereof being best seen in the FIGS. 8, l0 and 21 to 25 of the drawings. Referring first to FIG. 8, the file drawer 270 includes a bottom wall 271 that is generally rectangular in shape and has a width slightly less than the inner width of the pedestal 150 and a length slightly less than the length of the pedestal 150 (see FIG. 10 also), the longitudinally extending edges of the bottom wall 271 carrying inner side walls 272 integral therewith and extending upwardly therefrom substantiall normal thereto and substantially parallel to each other. Joining the rear edges of the side walls 272 and the bottom wall 271 is a rear wall 273. The side walls of the drawer 270 are of double wall construction and accordingly there is provided on each of the inner side walls 272 an outer side wall 274, the outer side walls 274 being identical in construction whereby only one will be described in detail, each outer side wall 274 being formed of a single piece of sheet metal bent to provide the several parts thereof. More particularly, the outer side wall 274 includes a bottom flange 275 (see FIG. 21) that lies beneath the underside of the bottom wall 271 and extends outwardly beyond the adjacent inner side wall 272 and upwardly to provide a lower support flange 276, the material being folded to provide a double thickness at this point; integral with the lower support flange 276 is a retaining flange 277 and also integral with the support flange 276 is an upstanding connecting wall 279 that connects with an upper support flange 278 also of double thickness construction and being formed integral with a connecting section 282 (see FIG. 8 also); the upper end of the connecting section 282 is integral with an outstanding reinforcement section 283 that in turn is integral with the attachment section 284. As illustrated, the bottom flange 275 lies against the undersurface of the bottom wall 271 and is suitably secured thereto as b Welding, while the connecting wall 279, the connection section 282, and the attachment section 284 are all disposed against the outer surface of the associated inner side wall 272 and are likewise suitably secured thereto as by weldng. By contrast, the reinforcement section 283 is spaced outwardly with respect to the adjacent inner side wall 272. The upper edge of each of the inner side walls 272 carries outwardly directed holding flanges 286 which in turn carry on the outer edge thereof an upwardly directed and upstanding flange 287 which in turn carries on the upper edge thereof an inwardly directed top flange 288 carrying on the inner edge thereof a depending retaining flange 289, all as will be described more fully hereinafter.

The file drawer 270 is supported within the pedestal 150 on a pair of lefthand rollers 290 (as viewed in FIGS 1, 2, 8 and 21), a pair of righthand rollers 290A and a pair of lefthand guides 300. Each of the rollers 290 includes an inner race 291 (see FIG. 10), a mounting shank 292 and a plurality of ball bearings 2'93 disposed on the inner race 291 and held thereon by an outer race contained in a support member 294, the support member 294 having a support surface 295 around the outer periphery thereof, the support surface 295 being essentially cylindrical in shape and engageable with the support flanges 276 and 278 on the associated drawer. A bolt 296 passes through the roller 290 and through the shank 292 thereof and engages a threaded opening in the associated main wall 162 or 181, respectively, of the associated front frame 160 or drawer support 180, as the case may be. Associated with each of the lefthand rollers 290 is a guide 300, each of the guides 300 including a substantially rectangular body 301 having formed integral therewith and extending from one edge thereof a positioning stud 302 extending through a suitable opening in the associated main wall 162 or 181, as the case may be. The other end of the body 301 has an opening 303 therein for receiving therethrough the bolt 296 for mounting both the roller 290 and the guide 300 upon the associated main wall 162 or 181, as the case may be. Adjacent to the opening 303 but spaced a short distance therefrom and concentric therewith is a first arcuate recess 305 for receiving the shank 292 of the associated roller 290 therein, and also disposed concentric therewith and spaced farther out therefrom is an arcuate second recess 307 for receiving the support member 294 therein. Disposed above and below the body 301 are upper and lower wings 306 that extend laterally inwardl beyond the inner surface of the support member 294 and having inwardly facing inside guide walls 311 thereon and outwardly disposed outside guide walls 310 thereon. The distance between the guide walls 310 and 311 is slightly less than the distance between the inner surface of the retaining flange 277 and the adjacent outer surface of the connecting wall 279, whereby the guide 300 provides control of side movement of the file drawer 270 during the movement thereof between the storage position illustrated in FIG. 10 and an extended position wherein the major portion of the drawer 270 is disposed outside of the pedestal 150. Finally, the righthand rollers 290A are provided (see FIGS. 21 and 25) and each includes an inner race 291A, a mounting shank 292A and a plurality of ball bearings 293A disposed upon the inner race 291A and held thereon by an outer race on a support member 294A, the support member 294A having a support surface 295A about the periphery thereof that is substantially cylindrical. A bolt 296A passes through an opening in the inner race 291A and serves to mount the roller 290A upon the associated main wall 162 or 181, as the case may be. In passing it is noted that the width of the support surface 295 and the support surface 295A both are substantially less than the distance between the inner surface of the associated retaining flange 277 and the outer surface of the associated connecting wall 279, whereby control of the side movement of the drawer 270 is controlled only by the action of the guides 300.

Preferably the guides 300 are formed of a lubric material, the preferred lubric material being a synthetic organic resin, preferably an acetal resin such as that sold under the trademark Delrin. Likewise, it further is pointed out that when the file drawer 270 is in the storage position therefor illustrated by the dashed lines in FIG. 10, the major portion of the file drawer 270 is disposed inwardly or to the right of the drawer supports 180, whereby the major portion of the drawer 270 is mounted in cantilever fashion within the pedestal 150. As a consequence, the upper support flanges 278 contact the surfaces of the rollers 290 and 290A mounted on the drawer supports 180, whereas the lower support flanges 276 contact the rollers 290 and 290A that are mounted on the front frame 160. On the other hand when the file drawer 270 is in the fully extended position thereof, the major portion of the file drawer 270 is disposed outwardly or to the left of the front frame 160, whereby the major portion of the drawer 270 is mounted in cantilever fashion outside of the pedestal 150. As a consequence, the upper support flanges 278 contact the surface of the rollers 290 and 290A mounted on the front frame 160, whereas the lower support flanges 276 contact the rollers 290 and 290A that are mounted on the drawer supports 180.

Further details of construction of the file drawer 270, and particularly of the construction of the drawer head therefor, are illustrated in FIG. 30 of the drawings. As will be best seen therein, the top flanges 288 and the retaining flanges 289 are cut away at the forward or lefthand end of the drawer 270 and there are provided thereon front side flanges 315 extending upwardly from the inner side walls 272. The rear wall 273 further has formed therein an inturned U-shaped flange 316 on the upper edge thereof and extending substantially between the retaining flanges 289. Mounted on the forward end of the drawer 270 and extending beyond the side walls 272 and upwardly thereabove and downwardly therebelow is an essentially rectangular outer front wall 320, the lower end of the wall 320 extending below the bottom wall 271 as at 321 and having on the lower edge thereof a rearwardly directed fiange 322 carrying on the rear edge thereof an upturned flange 323 extending upwardly to the underside of the bottom wall 271 and carrying a rearwardly directed attachment flange 324 thereon. The upper end of the outer front wall 320 carries a U-shaped retaining flange 325 including a rearwardly and slightly downwardly directed portion 326 and a downwardly directed portion or flange 327, the flange 327 being disposed substantially parallel to the outer front wall 320. The bottom wall 271 has a pair of upwardly extending projections 328 struck therefrom. The outer front wall 320 is secured to the forward end of the drawer 270 such as by welding at the attachment flange 324 and at the forward edges of the side walls 272. Disposed within the drawer 270 but against the outer front wall 320 is an inner front wall 330, the wall 330 including a pair of laterally extending reinforcing ribs 331 having forward portions 332 and connecting portions 333, the ribs 331 extending the entire width of the inner front wall 330. The upper end of the wall 330 carries a forwardly offset flange 334 disposed in front of the downwardly directed flange 327 of the Z-shaped retaining flange 335, the flange 334 in turn carrying on the upper edge thereof a forwardly directed top flange 335 that in turn carries on the forward edge thereof an upturned front flange 336 disposed against the inner surface of the outer front wall 320. The bottom end of the inner front wall 330 carries a bottom flange 337 that is forwardly and upwardly directed and carries on the forward edge thereof a downturned front flange 338 disposed against the inner surface of the outer front wall 320. It will be seen that the construction of the drawer head including the outer front wall 320 and the inner front wall 330 of the drawer 270 is substantially like that of the drawer 210, and in the interest of brevity the manner of assembly will not here be repeated, it merely being pointed out that bodies of mastic 339 are disposed between the wall 320 and the parts 331, 328 and 336 and insure that the upper end of the inner front wall 330 is retained within the U-shaped retaining flange 325 and together with the projections 328 insure that the lower end of the inner front wall 330 is held in position immedi ately adjacent to the outer front wall 320.

There further is provided within the file drawer 270 a compressor plate 340' (see FIGS. 30 to 34, inclusive), the compressor plate 340 serving to hold the material stored within the file drawer 270 in the forward portion thereof and against the drawer head in the usual manner. The compressor plate 340 includes a main body 341 which is generally rectangular in shape (see FIG. 32) having square lower corners and having formed intermediate the height thereof a rearwardly disposed reinforcing rib 349 and having formed toward the upper end a rearwardly directed flange 342 carrying an upstanding flange 343 which in turn carries a forwardly directed flange 344 to which is integrally connected an upper body 345, the upper body 345 having a U-shaped curved and rearwardly extending handgrasp portion 346 on the upper end thereof including an inturned flange 347 disposed therebeneath for reinforcement purposes. There further are provided in the flange 343 a pair of openings 348 by means of which a pair of guide brackets 350 are attached to the compressor plate 340, the righthand opening 348 being elongated to permit adjustment. The guide brackets 350 are substantially identical in construction, one being the mirror image of the other. As illustrated, each of the guide brackets350 includes an attachment flange 351 which extends laterally of the drawer 270 and fits between the flanges 342 and 344 of the compressor plate 340 and against the flange 343 thereof, the guide brackets 350 having circular openings 352 therein to receive screws 353 therethrough for attachment of the guide bracket 350 to the compressor plate 340, the elongated righthand opening 348 permitting adjustment of the righthand guide bracket 350 with respect to the compressor plate 340 thereby to accommodate minor variations in the width of the drawer 27 0. In passing it is noted that as illustrated in FIGS. 30 and 34, the forward surfaces of the attachment flanges 351 are in substantial alignment with the forward surfaces of the main body 341 and the upper body 345 of the compressor plate 340. Integral with each of the attachment flanges 351 is a forwardly directed arm 355. The arms 355 are adapted to lie upon the holding flanges 286 disposed on the upper edges of the drawer 272 and to extend upwardly into the space between the upstanding flange 287 and the inner flange 289, whereby the arms 355 are restrained in the vertical movement by the holding flange 286 and the top flange 288. As may be best seen in FIG. 34, each of the holding flanges 286 has a series of openings 312 therein, the openings 312 being rectangular in shape with the longer dimension thereof, disposed longitudinally of the drawer 270. The lower surface of each of the arms 355 carries a downwardly and rearwardly directed rear finger 387 thereon adapted to fit in one of the openings 312 (see FIG. 31) and a downwardly and rearwardly directed front finger 388 thereon adapted to fit in the adjacent forward opening 312. The upper surface 358 of each of the arms 355 slopes downwardly to the rear as is best illustrated in FIG. 30 from a point immediately below the top flange 288 at the forward portion thereof and downwardly to a point spaced just slightly above the flange 344 on the compressor plate 340 adjacent to the rear end thereof, whereby the arms 355 and the associated fingers 387 388 can be moved from the engaging or down position illustrated by solid lines in FIG. 30 and by the dashed lines in FIG. 31 to a disengaged or up position illustrated by solid lines in FIG. 31, the arms pivoting about the lower front end 359 thereof in a manner such as to clear the fingers 387 and 388 from the associated openlngs 312, thereby to permit longitudinal adjustment of the compressor plate 340 along the file drawer 270. It is po1nted out that such upwardly pivoting and longitudinal movement of the compressor plate 340 can be achieved by the user grabbing the handgrasp portion 346 at the upper end of the compressor plate 340, whereby to move the parts to the solid line positions illustrated in FIG. 31. When the compressor plate 350 is in the substantially desired longitudinally adjusted position thereof, the user needs simply to release the handgrasp portion 346 whereupon gravity will tend to return the compressor plate 340 tothe lower position thereof and dispose the fingers 387 and 388 upon the holding flange 286. If the lower ends of the fingers 387 and 388 are in vertical alignment with a pair of adjacent openings 312, then the fingers 387 and 388 will fall thereinto, thereby fixedly to position the compressor plate 340 in the adjusted position with respect to the drawer 270. On the other hand, if the fingers 387 and 383 are not positioned vertically above an adjacent pair of the openings 312, then they will fall upon the upper surface of the holding flange 286, and will be moved rearwardly therealong due to the pressure of the material contained between the drawer'head at the front end of the drawer 270 and the compressor plate 340, and as soon as the fingers 387-388 are moved over a pair of the openings 312, the fingers 387-388 will fall thereinto under the urging of gravity, thereby automatically to position the compressor plate 340 within the drawer 270.

' Mechanism is provided for locking the drawers 210 and 270 Within the pedestal 150 in the storage positions thereof, and also to lock the center drawer 380 in the storage position thereof Within the desk top 101. To this end a lock 360 has been provided in the front edging 103 of the desk top 101, the lock 360 being disposed generally centrally of the desk top 101 and over the center drawer 380 therein. The usual key opening is provided whereby upon insertion of the proper key, the parts can be turned between the locked position thereof and the unlocked position thereof. In the operation of the lock 360 by means of a key a flexible wire cable 364 is moved,

the cable extending along a latch channel 370. The latch channel 370 includes a main wall 371 suitably secured to the adjacent pedestal side wall 153 as by welding and having extending forwardly therefrom a pair of side walls 372 from which extend laterally outwardly a pair of first retaining flanges 373 from the outer edges of which extend inwardly directed support flanges 374 on the inner edges of which are a pair of inturned second retaining flanges 375. At the upper end of the latch channel 370, the second retaining flanges 375 are provided with cutouts 376 therein for insertion of latches as will be described more fully hereinafter. The latch channel cable guide 367 is fixedly secured in the upper end of the latch channel 370 and has a curved bearing surface 369 that directs the cable 364 through a 90 angle turn so as to direct the cable downwardly and along the length of the latch channel 37 0.

Referring to FIG. 8, it will be seen that disposed within the latch channel 370 is a pair of latches 385, a latch 385 being provided for the box drawer 210 and a latch 385 being provided for the file drawer 270. All of the latches 385 are of identical construction, whereby only one will be described in detail with special reference to FIGS. 5 to 10, inclusive. Each of the latches 385 is more particularly mounted upon an associated latch block 386 that is shaped and formed to move vertically within the latch channel 370 between the two sets of retaining flanges 373 and 375, the associated latch 385 extending outwardly into the pedestal body and being formed integral with the latch block 386 (see FIG. 6 particularly). A vertical opening is provided in the rear of the latch block386 to receive the cable 364 therethrough and the block 386 is staked as at 377 to connect the latch block 386 to the cable 364. The latch 385 includes an abutment surface 387 which engagesa keeper on the associated drawer to provide the locking action, and'also has thereon a cam surface 388 which is useful in permitting an open drawer to be moved to the storage position while the locking mechanism is in the locked position thereof and without the necessity of moving the parts to the unlocked position thereof. Finally, the lower latch block 386 is engaged by a spring 389 (see FIG. 10) having the upper end thereof connected to the latch block 386 and having the lower end thereof fixedly connected to the lower end of the latch channel 370. i

In order to complete the locking mechanism, each of the drawers in the pedestal is provided with a keeper on the outer side wall thereof. Referring to FIGS. 5 to 8 of the drawings, it will be seen that a keeper 220 including an attachment flange 221 has been provided on the outer side wall 214 and particularly on the connecting section 222 thereof and secured thereto as by welding, the keeper 220 extending laterally outwardly substantially normal to the associated drawer side wall. When the latch 385 is in the upper or latching position thereof, the abutment surface 387 thereof is in horizontal alignment with and immediately disposed in front of the keeper 220, whereby the drawer 210 is locked in the storage position thereof. However, when the latch 385 is moved to the release position thereof, it is out of alignment with the keeper 220, whereby the drawer 210 may be moved between the storage and extended positions thereof. The necessary movement of the latch 385 between the latching and release positions thereof is obtained by the operation of the lock 360 to move the parts from the locked position illustrated to the unlocked position. The file drawer 270 likewise is provided with a keeper 280 (see FIG. 8) which engages an associated latch 385 in the same manner as the latch 385 engages the keeper 220 on the box drawer 210.

The latches 385 also serve as an outer stop to limit the distance that the drawers 210 and 270 can be withdrawn from the pedestal 150 without complete removal thereof. Referring particularly to FIGS. and 7, of the drawings, it will be seen that there has been provided on each of the drawers 210 and 27 0 a stop arm or bracket 225 that is essentially U-shaped and is attached to the outer side wall of the associated drawer and in horizontal alignment with the latch 385 when it is disposed in the release position thereof, i.e., the lowermost position thereof as illustrated in FIG. 7. Mounted in the stop bracket 225 is a rubber bumper 229, and accordingly, upon withdrawl of the drawer, such as the drawer 210, from the pedestal 150, the bumper 229 abuts against the abutment surface 387 on the latch 385, thereby to limit the withdrawal of the drawers from the pedestal 150. However, should it be desired completely to remove a drawer from the pedestal 150, the locking mechanism need only be moved to the locking position after partial withdrawal of the drawer that it is desired to remove, such movement of the parts to be looking position shifting the latch 385 to the upper or locked position so that the stop bracket 225 and the bumper 229 carried thereby now clear the latch 385, whereby the drawer 210 can be completely removed from the pedestal 150.

Due to the fact that the latches 385 are continually urged toward a lower position thereof by means of the spring 389, each of the latches 385 can be momentarily shifted upwardly by the application of suitable force to the cam surfaces 388 thereof. For example, if a drawer 210 or 270 is in the partially open or extended position thereof, and thereafter the locking mechanism is placed in the locked position thereof so as to move the latches 385 to the upper or locked position thereof, the latch 385 will be in longitudinal alignment with the keeper 220 or 280, as the case may be; however, the keepers have the upper edge thereof disposed slightly below the upper edge of the latch 385 when it is in the latching position thereof, whereby the upper edge of a keeper engages the cam surface 388, thereby to move the latch 385 and the associated parts upwardly against the action of the spring 389 until the keeper passes behind the abutment surface 387 on the latch 385, after which the spring 389 automatically returns the latch 385 to the latching position to engage in front of the keeper and prevent subsequent withdrawal of the drawer until the latch 385 is moved to the lower or release position thereof.

Fundamentally the desk 100 is formed of sheet metal with the exception of the several parts mentioned during the above description. Furthermore, the sheet metal forming the various parts is of relatively light gauge, as will be appreciated from the following example of the gauge of the sheet metal utilized to form various parts of the desk 100. In a typical construction of the box drawer 210 and the file drawer 270, the bottom side and rear walls thereof are formed of 24 gauge steel, the outer front walls thereof are formed of 22 gauge steel, the inner front walls are formed of 26 gauge steel.

The other parts of the desk not described in detail hereinabove are fully illustrated and described in the above-mentioned copending application Ser. No. 503,517, new Patent No. 3,368,955, and accordingly reference is made thereto and the disclosure thereof incorporated herein in its entirety.

From the above description it will be seen that drawers of improved construction have been provided having side walls formed of double walls shaped to provide support flanges and retaining flanges and having a double wall head of novel construction and connection, a body of mastic being provided to interconnect the inner and outer walls of the drawer head to provide an improved connection therebetween. Finally, there has been provided in the drawer an improved compressor plate construction including in the improved compressor brackets molded of lubric material and constructed and arranged to provide for self-locking upon release thereof .due to the downward force of gravity and a rearward force resulting from the pressure of material lying between the front of the drawer and the compressor.
