9 Claims.

1 The present invention relates to containers such as filing baskets, sorting boxes, storage trays,

.etc. and has particular reference to such containers, hereinafter referred to as trays, which may be stacked upon one another for use in spaced relation and which may be nested within one another compactly when not in use.

An object of the invention is the provision of a storage tray which is formed in such a manner that a plurality of such trays may be readily and securely stacked one upon another to provide a series. of verticallydisposed bins or compartments which may be utilized for; filing or collating letters and other papers .or articles or for storing pages of. letters, booklets, or other articles arranged so that they. may be conveniently withdrawn for assembly into various classifications or forms.

. Another object is the provision of such a tray which is formed with co-operating lugs and notches for securing the trays, together against shifting or displacement when in stacked relation.

Another object is theprovisionof such'a storage tray which may bereadily and compactly nested one within anotherso that a-plurality of such trays may-be stored in a small space when not in use.

Stillanotherobject .is the provision of; such .a tray which may be drawn or molded economically from light weight material preferably in a single piece so that a plurality of such trays may be readily assembled or otherwise handled with ease.

Another object is. the. provision ofsuch-a tray which is formed for co-operation with a' bracket, supportor display'stand for holding a plurality of stacked. trays in an angular position while simultaneously. retaining flatsheetsor other articles on the trays in a convenient arrangement for ready classification or withdrawal.

Numerous other objects and advantages .of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings:

.Eig; 7 is a reduced scale perspective View of the .holdershown in Fig. 6; and

Fig. 8 ,is an enlargedsectional view .taken through the traysand the holder shown inFig. 6, withparts brokenwaway.

:Asal refen-ed or exemplary embodiment of the invention. the drawingsflisclose a v generally rectangular shaped traypreferably made of a one- .piece lightweight sheet metal. ,The tray preferably comprises a-flat rectangular bottom Wall ll Fig. 1) surrounded by-apair ofupright side walls 12 and one end wall [Sconnecting the two side-walls. The two--side walls l2 andthe end wall iataperor flare upwardly, and outwardly at an angleslightly. greater than to the, bottom wall H so. that the trays will readily nest one within another.

bottom wall I l. projects forwardly beyond the side walls 1 2.: to proyide,.a;bottom wall extension [4 which .is disposed in the plane of thebottom wall ll.

.Thextwo. opposed side walls i 2 preferably are .the same height, and terminate in,upper straight edges, I6 which are formed with. shallow. rectangular notches or. recesses 1,1 [8 all of which are of the; same depth with their .bottomsdisposedin thesame horizontal plane. ,There is oneeach of thesenotches [1.18 in eachwall edge '16 land they are spaced 1a,; predetermined. distance apart andarelocated one .adjacenteach end of the side walls I 2. The notches; ll constitute frontnotches and the notches l8 constitute-rear notches. .The notches l1, H3, in. onewall. edge 46 are disposed directly opposite -and in alignment with the notches intheopposite. wall. edge.

. :The height; of. the endawall l3- is substantially equalxto the distance..between, thegbottom of the notches. [1,. l8 and thebottomiwall section: I I so that. the. top nterminaledge; of the end wall; section, which preferably is straight, is :in: thasa and the two lugs are directly opposite and in alignment with each other. The lugs extend upwardly from the outer edge of the bottom wall extension at a Slight angle thereto and terminate in a hook 2i. The distance between the two opposing hooks 2! is substantially the same or slightly greater than the distance between the bottom edges of the front notches ll in the two side walls i2. The width of the hooks is substantially equal to but not greater than the width of the notches i'l.

Between the front notches H and the rear notches E3, the side walls l2 are cut away the full height of the walls to provide rectangular openings 23 in each of the side walls l2 for nesting purposes to be described. These openings are directly opposite and in alignment with each other. At the base of the opening 23, the bottom wall I l is formed with two rear support lugs or tongues 24 which are similar to the lugs or tongues i9 and which extend outwardly from the edge of the bottom wall II. There is one lug on each side of the bottom wall i l. The lugs extend upwardly at a slight angle to the bottom wall section and terminate in hooks 25. The width of these rear lugs 24 is substantially equal to but not greater than the width of the rear notches it and the width of the openings 23. The two lugs 24 are spaced from the front lugs H! the same distance that the front notches ll are spaced from the rear notches Id. The transverse spacing of the rear hooks 25 is substantially the same or slightly greater than the distance between the bottom edges of the rear notches l8 in the two side walls I2. The width of the openings 23 in the side walls i2 is substantially equal or slightly greater than the width of the rear lugs 2%.

Hence with such an arrangement of spaced front and rear notches l'l, l8 and front and rear lugs E9, 24, a plurality of trays may be readily stacked vertically one upon another as shown in Figs. 2 and 3 to provide a plurality of compartments or bins into which articles or sheets may be readily stored. and from which they may just as readily be withdrawn. In such a stacked relation, the front support lugs iii of one tray fit into the front notches ll of another tray with the hooks 2| of the lugs resting on the bottom edges of the notches and thus supporting the upper tray. In a similar manner the rear support lugs 24 of the upper tray fit into the rear notches it of the lower tray with the hooks 25 of the lugs resting on the bottom edges of the notches and thus supporting the upper tray. Along the rear portion of the trays, the bottom wall ll of the upper tray rests on and is supported by the top terminal edge of the rear end wall it of the lower tray. Thus the upper tray is completely supported by the lower tray and is secured against shifting or displacement by the lugs and notches in the trays, while the front of the trays remains open for reception of sheets or other flat articles. With such a manner of supporting and locking the trays together any number of trays within reason may be stacked one upon the other to provide a vertical series of compartments for a required use.

When the trays are not in use any number of them may be readily nested one within another to occupy a small storage space as shown in Figs. 4' and 5. The tapered side and end walls permit of this easy nesting feature. Another feature is that since the trays are all alike and of the same proportions, the openings 23 and the lugs 89, 24 in all trays are spaced the same distance from the end walls l3, and thus provide for vertical nesting of the rear lugs 24 in the openings 23 and complete vertical nesting of the front lugs 59 immediately in front of the forward edges of the side walls l2, to form a compact nest of trays as shown in Fig. 4.

Provision is also made for holding a stack of the trays in an angular position and to retain sheet material in the trays in an obliquely stacked relation to facilitate display or withdrawal of the material from the trays. For this purpose the entire stack of trays is supported in a holder 3i (Figs. 6, 7 and 8) and locked against displacement therein. The holder 3| preferably made from a single blank comprises a flat base 32 having a front vertical wall 33 of a desired height and a width slightly greater than the width of a tray for supporting the lowermost tray of a stack of such trays, in an angular position adjacent the front support lugs 19 of the tray. The rear edge or" the lowermost tray rests on the holder base 32 as best shown in Figs. 6 and 8.

The top terminal edge of the front vertical wall 53 of the holder 3i is formed with a wide shallow notch 33 (Fig. '7) having a width slightly greater than the width of a tray. When the tray is in the holder as shown in Figs. 6 and 8, its front end fits within the holder notch 34 with the bottom wall H of the tray resting on the bottom of the notch and the rear edge of the laterally projecting front support lugs H! of the tray engaging against the outer face of the front wall of the holder (Fig. 6). Thus the tray is locked against transverse and longitudinal displacement.

In this inclined position of the stacked trays on the holder support 3!, the rear end wall I3 of each tray is supported by a vertically disposed serrated retaining wall 36 extending longitudinally of the holder base 32. This retaining wall 36 may be struck out from the base 32 and bent upwardly into supporting position as shown in the drawings or may be a separate wall if desired. The top terminal edge of the retaining wall 36 is generally inclined and is provided with a series of spaced steps or serrations defined by downwardly inclined faces 3'! and upwardly inclined faces 33. The downwardly inclined faces 3? are parallel with and support the bottom walls ll of the stacked trays in the holder (see Fig. 8). In a. similar manner, the upwardly inclined faces 38 are parallel with and support the end walls is of the stacked trays in the holder. Thus each step supports the back corner of one of the trays in the stack and thus collectively the steps hold the entire stack in its inclined position. Only the lowermost tray is partially supported by the holder base 32, the base in this instance providing one face of the adjacent step.

Besides supporting the back end of each tray in the stack, the stepped edge of the retaining wall 35 also locks the stack of trays against transverse movement. This is brought about by a series of retaining projections 39 which extend outwardly and forwardly from the upwardly inclined faces 38 of the longitudinal serrated tray retaining wall 35. Each projection 39 extends through a verti al slot or opening til (see Figs. 1, 2, 5 and 8) formed in the rear end wall i3 and partially in the bottom wall ll of the respective trays. The width of the slot is substantially equal to the width of the retaining projection 39 and thereby eliminates loose play so that a said projection, by reason of its positioniinthe slot of a said tray,llocks the trayagainst transverse movement. V

The retaining projection 39 serves a dual purpose in that it engages the back edge of sheet material in the tray and thus retains the material in a desired position relative to the tray. As shown in Figs. 6, 7 and 8 of. the drawings the projection-3s preferably is formed with a vertical-front face as although this face may be disposedat a different angle if desired. At the preferredangle, the face $2 in engaging against the back edges ofthe sheet material in the trays, shifts the sheets into an obliquely positioned stack with the front edges of the sheets separated andin overhanging relation to each other. Thus removalof-the sheets individually from the trays isreatly facilitated.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention orsacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
