' DRAWER SUSPENSION AND cuinE STRUCTURE Filed April 19,1955 2 Sheets-Sheet 2 ,42 4 42 I W INVENTORS 43 RAYMOND H.RE|S S w I)? 8,. ROBERT RANDALL r I mum. HAHN MLQM MW United States Patent Of ice to Reiss Manufacturing Corporation, New York, N. Y., a corporation of Delaware Application April 19, 1955, Serial No. 502,314 2 Claims. (Cl. 312-347) This invention relates to a sliding drawer construction, of the type used in furniture, and, particularly, in

bureaus, cabinets, and desks. The novel drawer construction includes improved means for slidably supporting a drawer so as to render the sliding movement thereof quiet and facile.

The principal diificulty encountered in the manufacture and utilization of sliding drawers is the fact that such structures tend to become difiicult to operate after prolonged use. With respect to wooden drawers, a loose fit is usually necessary to allow for expansion of the wood members during periods of high humidity. Thus, the normal wear and tear on a drawer can be quite severe and the constant strain on the support means usually results in a faulty running drawer. It can be appreciated that such breakdown in the drawer construction can result in inefliciency as well as inoperability of the drawer structure.

Efforts have been maintained to facilitate the sliding movement of a mounted drawer by means of efiicient, yet economical support and guide members. Roller bearings have been typically used but are very expensive and, in addition, are susceptible to mechanical breakdown and noise.

With the above in mind, the primary object of this invention is to provide a drawer support and guide structure adapted to reduce the effort required to move the drawer and, in addition, to provide quiet operational movement.

A more specific object of the invention is to provide a sliding drawer construction comprising a frame having a drawer compartment, a drawer shiftable in said compartment, means for slidably supporting and guiding said drawer, said means comprising a longitudinally extending guide rail mounted within said frame beneath said drawer, a guide member secured to said drawer and disposed beneath the central portion thereof, said guide member being slidably mounted on said guide rail by T-slot connection and the portion of said member engaging the said rail being of an anti-frictional material adapted to enhance the sliding characteristics of said guide member, and an anti-frictional guide element secured to said frame on each side of the forward end of said drawer compartment, said elements having surfaces in edgewise engagement with the undersurface of said drawer to thereby slidably support and laterally guide the same.

An additional object of the inveniton is to provide an improved sliding drawer construction and arrangement including nylon wear blocks mounted on the forward portion of the drawer compartment to thereby slidably support and laterally guide said drawer.

A further object of the invention is to provide a sliding drawer construction including a metal guide rail which is a structural member of the frame in which the drawer construction is incorporated, said guide rail cooperating with a nylon guide member to serve as the drawer back support and guide.

Still another object of the invention is to provide improved mechanisms to accomplish the foregoing objectives, which can be applied to an existing structure without major modifications.

Other and further objects and advantages of the pres- 2,857,233 Patented Oct. 21, 1958 cut invention will be apparent from a consideration of the following description of a specific embodiment shown for purposes of illustration in the accompanying drawings in which:

Figure l is a fragmentary perspective view showing a frame including a guide rail to furnish center support and nylon guide elements to furnish side support of the drawer compartment;

Figure 2 is a perspective view showing the drawer in phantom line, and showing a segment of the guide rail as well as the guide member mounted on the back of the drawer compartment;

Figure 3 is an exploded perspective view of a modi fied form of the guide member and rail;

Figure 4 is a sectional view of a mounted drawer showing guide rail and guide member as well as guide element positioned to support said drawer;

Figure 5 is a transverse sectional view through the guide member, taken on the line 5-5 of Figure 2;

Figure 6 is a fragmentary sectional view showing the preferred form of guide element mounted on the front portion of the drawer compartment; and

Figures 7-10 are fragmentary sectional views showing modifications of said guide element.

In the accompanying drawing, the support and guide means are shown diagrammatically and only those parts are illustrated which are required to show the cooperative relation of the ins'trumentalities of the present invention with the drawer and frame.

The improved sliding drawer construction embodying this invention is shown with respect to the metal frame 10 illustrated in Figure 1, having guide rails 11 integral therewith and adapted to slidably mount a tier of drawers through the coaction of said guide rails 11, guide member 12 (Figures 2-5), and guide elements 13, the latter being specially formed drawer support wear blocks.

The frame 10 may be of any suitable construction. It is herein shown as formed of metal frame members and comprises front and rear uprights 14 and 15 between which extend cross members 16 and 17. The guide rails 11 are also a part thereof, as noted above.

The drawer 18 (Figures 2 and 4), wherewith this invention is associated, can also be constructed of metal. It is formed in the usual manner with a depth and width dependent upon the size of the frame 10 and the number of drawers arranged therein.

The guide rails 11 cooperate with guide member 12, the said guide member being slidably mounted on said guide rail by T-slot connection. The portion of said guide member 12 engaging said rail 11 preferably comprises a liner 19 (Figure 2)' of anti-frictional material, such as nylon, having a horizontal upper wall 20 and dependent angular flange portions 21 on each end of said wall. Metal plate 22 embraces said liner and a stud 23 is integral with the liner and is used to attach the said liner to the metal plate as shown in Figure 5.

Guide member 12 also includes a plate 24 having holes 25, which are utilized to fix said guide member to the back to the drawer 18 as illustrated in Figure 4.

In mounting the guide member 12 on said drawer 18, it should be noted that the lower margin of the drawer is cutaway in the area where the guide member is affixed thereto. As shown at 26 (Figure 4), sufiicient clearance is provided for the drawer to avoid the guide rail during actuation thereof.

The guide rail 11 can comprise a channel 27 having the free edges of the legs thereof turned outwardly to provide marginal flanges 28. As illustrated in Figure 2, the flanges 21 and wall 20, of guide member 12 embrace the liner 19 and these elements together define a T-slot which is mounted on the marginal flanges 28- of said guide rail 11.

Figure 3 illustrates a modified form of guide rail and guide member. In this modification, the T-slot is provided by a guide rail including a channel 29 having the free endsthereof turned inwardlyto provide marginal flanges 30 forming the said T-slot. The modified guide member includes plate 31, to be attached tothe drawer, and a bar of anti-frictional material 32 attached to plate 31 as shown and engageable in said T-slot.

The guide elements 13 are mounted on the forward portion of the drawer compartment as shown in Figure l. The preferred form of these guide elementsis illustrated in Figure 6.

The guide element 13 includes a horizontal wall 33 having a stud 34 depending therefrom for securing said element to the frame 10. An upwardly extending vertical wall 35 is spaced inwardly from one end 36' of the horizontal wall 33. Strengthening means comprising triangular side walls 37 extend betweenthe top of the said vertical wall 35 and the said end 36 of the horizontal wall 33.

The surface 38 of said vertical wall and the upper surface 39 of said horizontal wall extending from the said surface 38of said vertical wall define drawer engaging surfaces. These surfaces act to support the drawer .8 on each side thereof and coact with guide member 12 and guide rail 11 to form the novel drawer suspension of the invention.

Figures 710 illustrate modifications of the guide element previously described with respect to Figure 6.

In Figure 7, a guide element is shown including a V- shaped wall 40 to which is attached a stud 41, said stud functioning as a securing means. The surface of this V-shaped Wall engages the drawer 18 to thereby slidably support and guide the same.

The modification of the guide element shown in Figure 8 includes horizontal surface 42 having stud 43 depending therefrom. An upwardly extending vertical wall 44 is spaced inwardly from one end of the horizontal wall. An upper horizontal wall 45 extends laterally from the top of the vertical wall 44 to operate as a strengthening and spacing means. The horizontal wall 42 and vertical wall 44 furnish the drawer engaging surfaces as illustrated.

Figures 9 and 10 can be considered to show modifications of a tongue and groove assembly. In both illustrated modifications the surfaces 46 and 47, respectively, comprise the groove. The undersurface of the drawer 18, designated 48 and 49, respectively, functions as the tongue in the tongue and groove assembly. As can be appreciated, in both instances, the groove is the drawer engaging surface which slidably supports and guides the drawer.

The guide elements 13 and the guide member 12 provide the only points of contact between the frame 10 and the drawer 18. As noted heretofore, this novel support and guide system makes the sliding of the drawers much easier and more quiet than is alforded by the conventional direct sliding contact. To that end, the guide elements, and contact surfaces of the guide members, are formed of a tough material that has an inherent quality of lubricity so that they provide a smooth, slipping contact with the parts which they contact. Synthetic materials such as nylon or Teflon have been found to possess this quality of lubricity to a very acceptable degree, yet are relatively inexpensive to manufacture. However, natural materials possessing the necessary characteristics might also be used.

Accordingly, they are preferably used in the present development. The result is a drawer which shifts with the ease comparable to that obtained by the use of roller bearings. materially less than that of roller bearing construction and noise is eliminated.

However, the cost of construction is In the operation of the apparatus of the present invention, guide elements 13 are suitably mounted in the front corners of the drawer compartment as illustrated in Figure 1. In addition, guide member 12 engaging guide rail 11 is attached to the center rear portion of they drawer 18. This system of support provides a three point suspension for the drawer, to wit, at its center rear area, and at each of the two sides. Thus, since the three points lie in a plane, the problems of drawer fitting and ease of operation, noted heretofore, are solved. When the drawer is moved, it rides on the guide rail through the contacting surface of the guide member, and on the guide elements, the result being that the drawer shifts with ease comparable, to a roller bearing construction.

It must be understood that the invention is not limited to the details of construction shown in the accompanying drawings and described above, but includes all the modifications coming within the scope of the appended claims and their equivalents.
