Villa, Gienside Gardens, Pa., assignor to Standard Pressed Steel Company, Jenkintown, Pa., a corporation of Pennsylvania Application February 3, 1952, Serial N 270,541 4 Claims. (Cl. 312-1l)7) The present invention relates to factory storage bins and more particularly to bins of the class which are capable of being stored in tiers.

One object of the present invention is to provide a storage bin of the stated class wherein provision is made for distributing the strains imposed on the bins, both by the stored articles and by a superimposed bin or bins, over a relatively large area of the bin structure, thereby reducing objectionable stress concentrations;

Another object of the invention is to provide a bin which is of relatively simple structural form and which is rigidly constructed so as to be proof against functional deformation;

A further object of the invention is to provide a bin of convenient form and superior functional characteristics, and

A still further object is to provide a bin which is structurally well adapted for handling by conventional lifttruck equipment; and which is provided also with means for dumping the contents by operation of said truck equipment.

The invention resides also in certain novel structural details hereinafter described and illustrated in the attached drawings, wherein:

Figure l is a perspective view of a single bin made in accordance with the present invention;

Figure 2 is a perspective view of a plurality of bins according to Figure l illustrated in tiered relationship;

Figure 3 is an enlarged sectional view taken on the line 3-3 of Figure 1;

Figure 4 is an enlarged sectional view taken on the line 44 of Figure 1;

Figure 5 is an exploded perspective view showing the forms of the various component parts of the bin structure;

Figure 6 is a fragmentary perspective view showing details of the bin structure within the area indicated by the broken line circle in Figure 1;

Figure 7 is a side elevational view of a modified form of bin provided with means for dumping the contents by operation of conventional lift truck equipment, and

Figure 8 is a front elevational view; partly in section, illustrating structural details of the bin as Well as the mode of operation of the dumping means.

Referring now to the drawings, the bin is designated generally by the reference numeral 10 and comprises side walls 11, 11, a rear wall 12, a front piece 13 and a base portion 14. Co-extensive with and underlying each of the side walls 11, 11 is a

leg member

15, 15 respectively; and to provide reinforcement and protection for the corners of the bin, corner braces 17 are provided. A cross-brace 18 spans the top of the front member 13 to provide additional structural support for the bin.

Referring now to Figure 5, it will be noted that the various structural elements of the storage bin are formed and arranged to provide inherent structural stability in the bin structure. The upper extremities 21 of the side walls 11 are bent angularly inwardly and upwardly and then outwardly to form a horizontal flange 22 Which in 1 The angle members 17 at each corner of turn is bent upwardly at 23 to provide a channeled guideway and seat for the leg members 15a of a superimposed bin Illa. Additional reinforcement is provided by bending the metal of the flange 23 back upon itself, as indicated at 23a, to afiord in effect a double thickness.

At their lower extremities, the side walls 11 are provided with inturned flanges 24 which terminate in downwardly depending lips or flanges 25 and which with said inturned flanges form angular sockets or seats for the leg members 15. The leg members 15 are formed from a generally rectangular blank, the blank being bent inwardly along its peripheral edges to form a recessed structure having a vertical base Web 26 and inwardly projecting

peripheral Walls

27, 28, 29 and 30. With reference to Figure 4, the upper wall 27 of each leg member is dimensioned to seat against the lower face of the flange 24 of the side wall 11 so that the web portion 26 will be in alignment with the Wall 11, the leg, in efiect, constituting a continuation of the wall 11.

The base member 14 is formed integrally with the rear wall 12, see Figure 5, and is adapted to seat upon the upper surface of the lower flanges 24 of the side walls 11. The rear wall 12 is cut out at its upper extremities to conform in contour with the angularly bent portions 21 of the side walls 11 and is similarly provided with an inturned flange 32 which is bent downwardly at its extremity to form a vertical lip 33.

The front member 13 constitutes a chute for ready access to the interior of the bin. The forward Wall 35 of the front member extends angularly outward and upward from the forward edge of the base member 14, and vertical side walls 36 extend inwardly towards the vertical front edges of the side Walls 11. The inner extremities of the side walls 36 are provided with outturned flanges 37 which at their upper extremities bear against the cross brace 18 as more fully described hereinafter. The upper peripheral edges of the side walls 36 and of the Wall 35 are turned back upon themselves as indicated at 36a and 35a, respectively, to reinforce the upper edges of the front member 13.

The lower terminal edge of the forward vided with an inturned horizontal flange between the lower face of the base 14 fronting upper faces of the flanges 24 of the Wall 35 is pro- 33 which seats and the conside walls 11. the bin structurally reinforce said corners and provide sturdy interconnection of various elements of the bin. In this respect, the flange 22 extends outwardly beyond the side wall 11 so that the flange, in assembly, will find a seat upon the upper edges of the corner braces 17 to impart further structural support to the guideway or seat formed by said flange.

The cross-brace 18 consists of a channel member shaped at its outer extremities 39 to conform with the contour of the angular portions 21 of the side walls 11, and is adapted to span the space between the said walls, seating against the interior faces of the said flanges 37 and the said angular portions 21.

The construction of the bin is greatly facilitated by the aforedescribed structural conformation of the various component parts. The member 41 which forms the base portion 14 and the rear wall 12 is joined to the side Walls 11 by welding, as indicated for example at 42, 42 in Figures 1 and 4. These welds 42 extend continuously along the side edges of the base member 14 and continue up the joint between the side walls 11 and the rear wall 12. The side walls 11 are jointed to the upper part of the rear wall 12 by welds 43 as clearly indicated in Figures 1 and 4. To afford further rigidity the cross-brace 18 is seated between the angular portions 21 of the side Walls flush with the forward edges thereof, and is welded as indicated at 48.

sembly by a' suitable weld indicated at 44 in Figure 3, uniting the forward edge of the base member 14 with the lower extremity of the forward wall 35, and a weld (not shown) between the flanges 37 and the brace 18. As shown in Figure 6, the vertical edges of the flanges 37 will be spaced apart from the forward edges of the'side walls 11, said spaces being closed by the corner braces 17 as more fully described hereinafter.

The leg members 15. may then be seated against the lower face of flange 24 and the lip 25 of the side walls 11 and held in place by the corner braces 17 which are secured to the assembled structure by a plurality of welds indicated at 45 in Fig. 1. The welds are suitably located to reinforce the previously described joints as well as to provide for union of the leg members 15 with the side walls 11. 7

Because of the substantial strength and rigidity afforded by welded unions in addition to the neat internesting of the various structural components of the bin, the bin is extremely strong and substantially proof against deformation under load. ,Of particular importance is the construction of the guideways for the superimposed bins 10a. The angular portion 21 is, in effect, a continuous supporting strut for the interior edge of the, guideway, this support being reinforced by the. cross brace 18 and upa per terminal portion of the rear wall 12. The outer edge of the guideway is reinforced to a great extent by the double thickness of metal indicatedat 23a in addition to the extra support aflorded by the corner braces 17 at the forward and rear ends of the guideway.

The lower flange 24 and the lip 25 also contribute to the strength and durability of the bin. In this respect, the lip 25 reinforces the flange against deformation, and, with the added support of the side 27 of the leg member 11, affords substantial support for the base member 14 along the full longitudinal dimension of said member.

The corner braces and the particular configuration of the various elements present a pleasing appearance and provide a factory storage bin free from rough edges and affording suificient hand holds together with suitable means for modern mechanized handling of the bins.

The bin illustrated in Figs. 7 and 8 is essentially of the same structuraldesign as that described above with the exception however that means has been provided for dumping the contents of the bin by way of the front wall chute through the medium of conventional lift truck equipment. To this end, each of the

leg members

51 and 52, which correspond to the members 15 of the previously described. embodiment, is provided with a pair of openings, 53 and 54 respectively, which constitute sockets for reception of the forks of the lift truck, one of said forks being shown in broken lines in Fig. 8 and being designated by the reference numeral 55. The openings in the leg member 51 are aligned with the respective corresponding openings in theleg member 52 and are spaced apart in the said leg members so that the forks of the truck may pass freely through the openings to occupy the position indicated in Fig. 8. The bin can then be elevated and transported by the truck to a desired point, and the con -tents of the bin or any part thereof dumped through the front wall chute 56 by tilting the forks and the bin laterally in' the appropriate direction by mechanism provided for that purpose on the truck indicated generally by the reference numeral 57.

In order to aflord a suitable bearing or seat for the forks 55 in the bin structure, I may provide

channel members

57 and 58 secured, preferably by welding, under and against the upper inturned

flanges

59 and 61 of the

leg members

51 and 52, as shown in Fig. 8. The bottoms of these channels lie flush with the uppenedges of the

openings

53 and 54 and thereby form the seats for the forks 55 as described above.

Preferred forms of the invention have been illustrated and described herein, but considerable deviation in the form of the parts and the method of assembly is pos-- sible without departure from the present invention as delined in the appended claims.
