BACKGROUND OF THE INVENTION Modular knockdown shelving for home and office is of increasing popularity particularly that which can be supported anywhere on a wall to provide open space between its lowest shelf and the floor or a desk top or table top. Ease of assembly and adjustment are important without the means being obvious by which such is accomplished, either for' locating the modular units themselvesof the positioning of the shelves for selected spacing between them. Heretofore a great deal of damage can occur to the walls in securing conventional modular shelving to the wall if it is not supported also from the floor. Furthermore, the appearance of such shelving may not lend itself to a decorative scheme including an appearance for ruggedness and strength.
Reference is made to Handler US. Pat. No. 3, l 39,258.
SUMMARY OF THE INVENTION The present invention is concerned principally with the mode of attaching modular shelving in a relationship supported solely by a wall without the securing means being obvious, yet is easily located and mounted, and at any time is readily adjustable.
A flat decorative pilaster having securement indicators is located on a wall with the bases of hooklike brackets serving as washers for the heads of screws which clamp the brackets and the flat member ruggedly in a predetermined spaced relationship for mutual positioning and proper leveling and spacing. A cross-sectionally M-shaped channel member having apertures through the concealed bight of its intermediate walls receives the ends of the hook members as guided by lateral decorative walls defining a recess and slips downwardly thereon in supported relation with the edges of the legs recessed slightly in the pilaster within either a wide recess or two parallel recesses for lateral support. End stop elements at either or both ends of the pilaster member hold the channel members against inadvertent movement out of the hook members while completing the unitary finished appearance of the assembly. Shelf supporting brackets are adjustably received in other apertures in the channel member and are readily removed without tools and quickly relocated, as more particularly described in said applications. In fact, if the shelves are first removed from their supporting brackets relocation can be accomplished without necessarily moving articles thereon. When slipped into place the shelves are held laterally as well as vertically in rigid securement, and, as more particularly described in Ser. No. 745,287, can be converted to cabinets.
Other and further objects and advantages include the economic benefits of mass production of a high-quality, uniform product of pleasing modular appearance with elements that are light and easy to handle and readily adjustable. Other and further objects will become apparent from the description and related drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, like numerals referring to similar parts through the description, the ends of two identical shelves 10 are shown as mounted on one of several pilasters l2 embodying the invention as affixed to a wall 14 that defines the rear plane of the perspective. Each of the shelves 10 has a top panel 116 (FIG. 3), a bottom panel 18 and the comers of the shelves have corner inserts 20 as more particularly described in Ferdinand, Ser. No. 845,173. Each shelf is supported at a point opposite a pilaster 12 by means of a bracket 22, only a small portion of each is visible in FIG. 1.
As more particularly described in the application Ser. No. 845,173 and as shown in FIGS. 3 and 6 the top panel R6 of each shelf 10 has integrally formed parallel front and back box flanges 26 and 28. The ends of the shelves merely have reversely bent flanges 30. Each box flange 26 and 28 being turned upwardly to fonn an object-retaining flange-type edge 32 and then rolled outwardly and downwardly to form the rounded or squared upper top edge 34 and front face of the flange. Then the flange is turned inwardly as at 36 to bound the inner wall 37 which at its upper edge is bent outwardly again to form the inner edge flange 38 which can be press fitted into the rolled edge 34 (FIG. 3).
The end flanges 30 of the shelf are differently formed by the interv omission of atop rolled edge such as 34 so that shelves located at the same level may abut at these ends one to the other in an essentially flat coplanar relationship as: rolled from an elongated tab at each'end of the blank sheet metal in forming thereof in a manner shown in Handler US. Pat. No. 3,304,760.
The bottom panels 18 are each flat and essentially rectangular, preferably conforming in shape to their matching top panel 16. Each of the bottom panels 18 has a pair of wall side notches 40 cut therein. The front edge and rear edge of each of the bottom panels 18 has like upstanding reinforcing flanges 42 running continuously or therealong.
The comer members 20, all of which are identical (FIGS. 5, 8 and 9) are constructed of hard rubber or plastic in a square or round design to fit within the cutout corners of the shelf having an ear press fitted in a box flange 26 or 28 and a cam lock protuberance that snaps into the adjacent end of the flange 30. Once in place, they are not easily removed and rigidify the shelf comers, particularly where they are not supported by the bracket 22.
Referring to FIGS. 4, 6 and 7, the structure of the pilasters 112 is shown more clearly to include a single-piece, elongated, extruded or roll formed cross-sectionally M-shaped metal channel member M comprising a pair of spaced walls 46 and 48, the back edges 50 of which are essentially coplanar and open therebetween. The pair of sidewalls are bent toward each other at the outer edges to from the rounded comers 62 and the flat front sections 54 and 56 along the entire length of the channel member. The walls 54 and 56 can be the same or of different widths but are spaced from each other a distance sufficient to receive therebetween at lease a single bracket 22 and preferably a pair of brackets 22 set side by side. The walls 54 and 56 are each again reversely bent as at 58 to form the continuous elongated channel 60 defined between the inner walls 62 and 64 and terminating in the bight wall 66 spaced discontinuously outwardly from the edges 50 and having a series of slots 68 therein for securement. This latter wall 66 and slots constitute a primary support element, supporting both fore and aft, the shelf brackets 22, as already described (FIG. 3), and a supported element when received on brackets 82 will now be described.
As shown in FIGS. 1, 2 and 3 an elongated decorative strip carved out of wood or molded out of pressed foam polystyrene is formed to serve as a plate 70 to have an elongated recess 72 on its front face, bordered laterally by decorative moldings 74, as shown in FIG. 3, or integral portions 74A as shown in FIG. 7. If separate decorative moldings 74 are employed the edges of the strip are marginallyflanged at 76 to retain them against lateral displacement and the moldings are preferably held by adhesive. The recess 72 receives the legs 46 and 48 of the channel member M snugly between them whereby it is rigidified laterally with decorative contours of the plate 70.
Shallow recesses 76 (FIG. 2) are provided at predetermined points spaced a multiple distance of the spaces between slots 68 to receive the flat base 80 of a sheet metal bracket 82 or 82A whose sides 88 or side 88A are bent inwardly at 84 to come together or be located at 86 beyond which in FIG. 2 the two sides are face to face and form a double thickness book 90 or, as shown in FIG. 8, a single thickness hook 90A, which is receivable from the rear through one of the slots 68. Matching holes 92 and 94 in the bottom of the recess 78 and the bottom wall 80 of the bracket 82 receive a suitable screw 96 whose head is accessible above the hook 90 or 90A and when driven into a wall stud 98 clamps the bracket and the decorative plate 70 in place to receive the channel member M a vertically spaced distance from its resting position after which it is moved vertically into its resting position against the bight of the hook 90 or 90A ready to receive the shelf brackets 22.
Also, flathead wood screws can be used through the pilaster plate 70 into the wall studding if desired for further shelf support in which case the lower shoulder 77 of the bracket recess transmits such support from the intervening pilaster plate material and through the shoulder 77 to the bracket 82 that is in engagement therewith.
The remote ends of the strip or plate member 72 extend beyond the ends of the channel member M when it is in place, and, as shown in FIG. 2, are fashioned to provide male members 100 of a dovetail joint having abutting square surfaces 102 and 104. bounded by outwardly diverging walls 105 or slip in locks 110A shown in FIG. 2A, or aligned recesses as shown in FIG. 2B. Then when the channel member M is in place ready to receive shelves it is secured against inadvertent release of its supported relationship.
Decorative end stop members 106 having mating female dovetail contours at 108, as shown in FIG. 2, are pressed into engagement with the male dovetails to lock the decorative end stop member 106 in place where it obstructs vertical displacement of the channel member M by upstanding end stop elements 110 abutting thereagainst. With one pilaster plate 70 being used end elements 110 need be used only at the upper ends.
In FIG. 2A, the upper portion of the end stop 106A is formed integrally with the plate 70A and a removable insert is employed between the integrally formed portion and the upper end of the channel M. For this purpose the plate 70A can be recessed or apertured as at 108A to receive end stop keys or stops 106B tightly in place against inadvertent removal to lock the channel M in place and to be removed when the channel is to be moved upwardly and forwardly.
Where two or more separate pilaster plates are aligned in use, they are mounted a spaced determined distance from each other as shown in FIG. and an insert 112 having like female dovetail contours 108 is slipped into place after the channels have been inserted, and the end stops 106 are utilized to finish the panel effect of the pilaster 12 at its extremities. Here again the insert 112 can be made integral as at 106A (FIG. 5A) with integrally formed aligned plates and a like opening 108A can be provided between the channels M to receive the keylock 106B releasable in place. The cross-sectional contour of the intermediate insert 106A can be uniform throughout its length or decoratively different to duplicate the upper end appearance of both sections.
In FIGS. 2B, 5B and 9 a simplified one-piece plate embodiment is shown in which a pilaster plate 12C is shown that can be molded in any length desired in relation to the length desired in relation to the length of the channel M. The integral end portions 1063 are spaced a distance less than the length of the channel M and when molded are cored out as at from the wall-engaging side of the plate 12C to provide recesses 122 by which the channel can be positioned in an inclined position as shown in broken lines 124 and slipped lengthwise into the upper recess 122U behind the front wall 123, then moved to a vertical position as shown in full lines 126 into the channel 72 of the pilaster as guided by the decorative sides 74 and lowered to engage the hooks 82A in slots 68 in which movement the lower end of the channel M is received in the lower recess 122L preferably without the upper end coming free of thevupper recess 122U. The upper end still being concealed behind the front wall 123, a person is not tempted to pull the channel M outwardly at the top, but rather must raise the channel M upwardly first to disengage the hooks 82A, then pull out the bottom end and thereafter remove the upper end of the channel M to free it if relocation is ever desired.
Thus a decorative strip or molding is provided bordering the channel member M to rigidify the channel member. Accordingly, a selected art or period decor can be provided and changed, if desired. The pilaster members M are slipped into place and locked in position and the shelves can be installed or readily changed.
In order of assembly of FIGS. 2 and 5 preferably is to use two pilaster plates 70 end to end with the insert 112 in place between them, fasten the plates in place with screws 96 and brackets 82 and then withdraw the intermediate insert 112. Slide mount the channel members M in place and then reinstall the insert 112 and the end stop 106. Thereafter shelves and brackets can be installed as more particularly set forth in said applicationsSer. Nos. 845,173 and 745,287, reference and incorporation of which are hereby made. In FIGS. 2A and 5A the assembly is to install the pilaster plates 70A of any selected length in place as indicated, slip the channels M in place and lock them against removal by insertion of the keylocks 106B.
Suffice to say here that with the shelves 10 mounted on the brackets 22 the shelf is tipped up at its front edge and the bracket hook ends 120 (FIG. 3) are inserted into the channel 60 and selected apertures 66 at the bottom thereof. The hook ends 120 are inserted with an upward motion to engage behind the bight wall 66 of the channel. The shelf is then lowered to hinge downwardly as permitted by the clearance at 122 and the lower protuberance 124 engages the bottom of the channel and holds the shelf rigidly in place.
The pilaster plate not only provides an easily located support means but prevents scarring of wall surface if removal or relocation of the modular shelving is ever desired. Only screw holes in the wall would be involved. These can be measured very accurately when being made and can be easily eliminated when no longer used.
