This is an invention for a knock-down shelving or shelf structure which, while not necessarily re- 3 Claims.

stricted thereto, is primarily designed to be sold in retail stores in knocked down unpainted condition so that it may be sold and taken home by the purchaser in a compact easily carried package and then painted to suit the individual taste of the customer.

.As an object, the invention comprehends a.

knock-down shelving which is so constructed as to be capable of beingeasily and readily assembled and secured in its set-up condition. by any use of tool and which shelving, when set-up,

. provides a structure possessing the requisite strength, rigidity andstability;

It is also afeature of the invention to provide an improved knock-down shelving which is so constructed as to facilitate the 'disassembly thereof so that the parts are capable of being com-- pactly stacked or nested together for packaging or storage or shipment.

Referring to the drawings by characters of reference, the knock-down shelving includes a pair of sidemembers A of substantially identical constructio'n, eachof which is preferably fashioned from a length of wooden board and is provided with a plurality of spaced .transverse slots l0 which are located intermediate the front and rear edges H and I2 of the side member, the slots of one member being adaptedto register with those of the other when the members are disposed in mating relation. When in use, the side members A are adaptedto be disposed vertically. in spaced side-by-side relation with the widths thereof parallel so that the slots 10. are in alignment with each other. The slots III are usually equidistantly spaced from one another but, in practice, the uppermost slot of each side memberis disposed in closer relation to the upper edge l3 thereof than the lowermost slot is to the lower edge I4 of the same.

The shelving also includes a plurality of shelf members B which are approximately of the same length as that of the side members A but of slightly greater width than the width of the side members and each shelf member is formed with a tongue l5 projecting outwardly from each of its opposite end edges l6 and ll andlocated intermediate the width of the shelf member. The

tongues l5 are of a cross-sectional size and shape to snugly fitwithin the slots ll] of the side members A and are so located as to dispose the front edges I8 of the shelf members B flush with the front edges ll of the side members A, when the said shelf members are assembled,with the side members. Thisdisposes the rear edge portions I 9 of the shelf members B in slightly protruding groove 20 is located in each of theupperand lower faces of the intermediate shelf member. It should also be noted that thefront wall 2| of each groove 20 is disposed slightly forward of the rear edges-l2 of the side members A, while edges l2. It will be further observed that the tongues l are of such a length that a substantial portion thereof protrudes from each of said slots 1 ii and beyond the outer side surface of each side member A when the end edges l6 and I! of the shelf members are in abutting relation with the inner side surfaces of the side members. The tongues are each provided with a vertical slot 23 extending through the thickness of the tongue and having an. inclined outer wall 24i spaced out- I wardly fromthe outer side face of theside members A, while the inner wall 25 of the slot 23 is spaced inwardly from the said outer face of the side member. A wedge element 26 is provided for. each ,slot 23 and is formed with an inclined outer face said rear; panel members. C are" preferably of.
