4 Claims.

This invention. relates to shelf structures-of the type known in the trade as 'credenzas and which include a plurality of shelves supported by and extending laterally outward beyond spaced vertically disposed side members.

The invention primarily 'comprehends an improved shelf structure of the indicated character which may be sold and delivered to the purchaser in a knockdown condition and which is so constructed that the same may be readily and conveniently assembled into set up condition by the purchaser.

The invention further embodies an improved shelf structure of said character in which the shelves and side members are constructed for interfltting relation and which includes rear panels having inter-fitting engagement with the shelves when the same are assembled with the side members so as to permit of the convenient and expeditious assembly of the shelf structure by the purchaser from a knockdown condition to-a set up condition ready for use and which may be disassembled and arranged in a compact 6 bundle for convenience in storage or shipment.

Fig. 4 is a perspective view of the parts of the shelf structure disposed in compact stacked arrangement for storage and shipment.

Fig. 5 is a fragmentary perspective view of a modified form of the invention.

Fig. 6 is a perspective view of another modified form of the invention with the parts shown in separated juxtaposition.

Fig. 7 is a vertical sectional view taken approximately on line 1--l of Figure 8.

Fig. 8 is a horizontal sectional view taken approximately on line 8-8 of Figure 7.

Referring to the drawings by characters of reference, the shelf structure includes a pair of similar side members In which are fashioned from plain wooden boards and arranged when in set up condition with their widths disposed parallel and in laterally spaced vertical relation.

The said members are formed with equally spaced parallel slots or notches I I which open through the rear edges l2 thereof and extend inwardly to a depth of approximately two thirds of the width of said members.

The shelf structure also includes a plurality of shelves l3, three being shown in the embodiments illustrated although two or-more may .be employed and which shelves are fashioned from plain wooden boards and formed with equally spaced parallel slots or notches ll opening through the forward edges l5 thereof and extending inwardly to a depth of approximately one-third of the width of said shelves and being spaced an appreciable distance from the opposite ends thereof respectively.

The shelves l3 are slightly wider than the side members lfland when in set up condition therewith project rearwardly thereof and are formed with longitudinally extending grooves IS in the confronting faces of adjacent shelves. The rear wall ll of each groove I6 is located adjacent the rearward edge H! of the shelves while the forward wall I!) of each groove is disposed slightly forward of .the rear edge l2 of the side mem-- bers Ill.

The shelves I! are interfltted with the side members ill by disposing the portions of the shelves directly rearward of the slots ll thereof in the slots ii of the side members and the portions of the side members directly forward of the slots I I thereof in the slots ll of the shelves and with the inner end walls of the slots H and I 4 in abutting relation, thereby disposing the shelves in vertically spaced horizontal relation with the intermediate portions thereof located between the slots 14 disposed in bridging relation between the side members and the opposite end portions of the shelves beyond the slots H projecting laterally outward of the side members.

The grooves it open through the opposite end edges 20 of the shelves and are adapted to slidably receive therein between adjacent shelves, panels 2| constructed of plain wooden boards which panels form a closure between the shelves at the rear thereof and provide a backing for the shelf structure so as to brace the same and secure the shelves and side members in horizontal and vertical relation respectively. The grooves ii are slightly wider than the thickness of the panels 2| and since the forward walls I! of the grooves respectively are located somewhat forwardly of the rear edges I! of the side mem-- bers Ill, a clearance is provided between the forward walls I! of the grooves and the longitudinal edge portions of the panels which permits the panels to snuglywflt against the rear edges of the side members In and th rear walls [1 of the grooves.

The shelves are rounded at the juncture of their forward and end edges and have their forward edges disposed flush with the forward edges of the side members. In order to secure the shelf structure in set up relation, fastening means such as screws 22 engage through the panels 2| with their ends anchored in the side members Hi to thereby prevent disengagement of the shelves and side members. Constructed in this manner, a shelf structure is provided-which is open at the front between the sidemembers and laterally thereof the same is open at the front and ends.

The side members to, the shelves l3 and the panels 2| are adapted to be arranged in compact stacked formation so that they may be tied together into a bundle for transportation, thus obviating the necessity of packing or encasing the shelfstructure for shipment.

If desired, the side members It! may be provided-in opposite faces thereof with mating grooves 24 which extend laterally from the the grooves 24 form shoulders which support the edge portions of the shelves l3 bordering the notches 26 which latter notches correspond to the notches M in the previously described form of the invention but are, somewhat narrower than the notches M in order to closely receive therein the web between the grooves 24. By this construction the forward portions of the shelves between the side members and laterally thereof have bearing engagement in the grooves 24 and are supported by the walls thereof.

In the form of the invention illustrated in Figures 6 to 8 inclusive of the drawings, the side members 21 and shelves 28 are notched for interfitting engagement but in this embodiment of the invention the notches 29 in the side members 21 extend inwardly from the forward edges thereof while the notches 30 in the shelves 28 extend inwardly from the rear edges thereof.

The shelves project rearwardly of the side members are formed with longitudinally extending grooves 3| in the confronting faces of adjacent shelves in which are received panels 32 which in addition to providing a backing for the shelf structure also serve to retain the shelves and side membersin assembled relation.

What is claimed is:

1. In a shelf structure of the indicated charactor, a pair of spaced vertically disposed parallel side members each having a plurality of vertically spaced parallel notches extending inwardly from a longitudinal edge thereof to a depth substantially two-thirds of the width of said member, a plurality of vertically spaced horizontally disposed shelves each having a pair of parallel notches spaced from the opposite ends thereof respectively and extending inwardly from a longitudinal edge thereof to a depth of substantially one-third of the width of said shelf, said side members and said shelves interfitting in said notched portions for supporting said shelves with the intermediate portions thereof disposed between said side members and with the opposite ends thereof projecting laterally outward beyondsaid side members and with the lower end portions of said side members below notches or grooves 'II to and open through the the lowermost shelf supporting the shelf structure with the lowermost shelf spaced from a supporting surface, said shelves projecting rearwardly of said side members and being formed with longitudinally extending grooves in the confronting faces of adjacent shelves, said grooves having their forward walls disposed forwardly of the rear edges of the side members and panel members extending longitudinally of the shelves and slidably fitted in said grooves and against .the rear edges of the side members for closing the back of the shelf structure between the shelves.
