5 Claims. 1

This invention relates to storage or display cabinets, and more particularly to a device of this character adapted to receiv and contain for storage or display, or both, relatively small objects either in boxed or unboxed form. The cabinet is also, of course, applicable to objects or boxes of large size, but, as disclosed, it is intended particularly for division into a large number of compartments, these compartments being arranged in rows or tiers, each row of compartments being characterized as a shelf. The size of the objects which the cabinet may be arranged to accommodate will, of course, depend upon the vertical spacing of the rows or shelves and the number of compartments in each row or, in other Words, the number of divisions provided upon each shelf.

In general, the device, as illustrated, comprises an open cabinet comprising end walls or supporting members between which extend the plurality of shelves or rows of compartments. These shelves, as illustrated, consist of a pair of stringer elements, which stringer elements may be secured to the end supports-or may be, as illustrated, secured together at their ends to form plurality of hanger members or brackets are employed. These brackets are, as shown, of substantially L-shaped form and consist of flat sheet metal stock, the ends of which will be secured or engaged in a satisfactory manner with the pair of stringer elements forming a shelf. The stringer elements are not only spaced from front to back but are also spaced one above the other, so that each end of one of the bracket members may be secured to one of the stringers.

Preferably the brackets may be engaged at any desired adjusted position along the length of the stringers so as to form divisions or compartments of any desired width without it being necessary to conform to any standard, so that compartments can be formed along each shelf of the proper width to accommodate the box or package regardless of the dimensions of the latter.

As will be apparent as the description proceeds, these hanger members or brackets are of two kinds, one having a flange projecting outwardly from its body portion, the flange here forming a partition or division between two adjacent compartments or being adapted to detachably receive a separate partition member forming the divi- 2 sion between the two compartments. The body portions of the brackets will form ledges at each side of a compartment upon which boxes or packages may rest, or if it is desired to employ the cabinet in connection-with loose articles of small size, to form ledges upon which plates may rest to form the bottoms and backs of bins for unboxed items.

One object of the invention is to provide a display or storage cabinet which may be econom ically manufactured principally from sheet metal parts of small size, so that scrap maybe employed in its manufacture if desired.

A further object of the invention is to provide a storage or display cabinet which may be eco-' nomically made from a relatively small number of parts, so arranged that they may be readilyassembled by an unskilled person without the use of special tools whereby the cabinets may be shipped in knocked-down condition and assembled after their receipt by the purchaser. A still further object of the invention is to provide a display or storage cabinet having a plurality of shelves or tiers of compartmentspthe compartments being formed by adjustable members so arranged that they may be given any de-' sired spacing to form compartments of any desired width.

A still further object of the invention is to provide a storage or display cabinet of the char acter described such that the spacing of the mem bers forming the compartments may be changed or adjusted at will by the user without the necessity of special tools.

A still further object of the invention is to pro vide a storage or display cabinet which may be economically manufactured and which will contain a large number of relatively small parts or boxes or packages within a compact space by means of the compact arrangement of a relatively large number of different compartments for pack-, ages of merchandise of assorted kinds.

To these and other ends the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

Io illustrate .a preferred embodiment .of my invention,.li have shown .in Fig. l of .thedrawings a .cabmetcomprisingend supports. or.fram emembers .Ill and .Isl whichmay be constructed vin .any manner desired, but which will preferably .be of sheet metal.so.-.as .to be light .in weight. .These end sections mayrbe held together either by the shelves themselves, as will be hereinafter explained, or, .if desired, :by suitable connecting members not vshown. It will be understood .that these end members may support th cabinet on theiloor, counter .or the like.

.Mounted between'these'end supports .and .extending from .one to the .other are a plurality of shelves or tiersof compartments disposed one above the. other and, while only two of such shelves are shown in the drawing, it will be understood that as many maybe employed as are desired. These shelves each comprise a frame which consists of apair of stringer elements 12 and lfl'whiohyas shown in this modification of my'invention, are of-rod like form and extend betweenrthesseotions 1'0 and .l The 'stringenelements [2 and I3 may be secured-directly to the end sections, but preferably their ends are socured to cross members .4 4 and 15, thus forming al-rectangular frame, the cross members in turn I being secured to the end sections by bolts or the like .l-l passing through the desired .ones of a plurality of openings l8 provided in the end sections. tl hus the frame andshelfas a :whole are pivotally mounted between .endrsections-and .zand1'5 of the drawings.

so may be disposed in a horizontal position as shown at the upper portion of Figs. 1 and 2 or in a tilted position as shown in the lower portion of these figures. Tightening of the bolts I! will secure the shelves in any angular position to which they may be adjusted.

As shown in Fig. 2, the rods or stringer elements I2 and I3 are spaced vertically and also from front to -back of the cabinet. With the stringer elements thus disposed, they are adapted to have engaged therewith the ends of the hanger members or brackets which form the compartments .for holding the boxed or unboxed articles.

These bracket members are shown in Figs. 4 That shown in Fig. 4 maybe considered as the left-hand bracket member of a-compartment and comprises a generally L-shaped flat body portion l9 provided with an outwardly projecting flange 20 standing at substantially right angles to the body portion. While, as shown, the'legs of the bracket are at substantially right angles to each other, this disposition of the :parts may be varied and the junction .of the two portions may be rounded or .may "be arranged .at any desired angle. At

their upper andlower ends, the .two parts of the bracket are .bent .upon .themselves as shown (at 2.! to provide loops .to embrace thestringer elements .l-Land 4.3. Adjacent their ends, tongues 22 may be stamped out of the body portion of the brackets .for a purpose to be hereinafter described. Also asshown in Fig. .8, the body :portionsof the brackets are provided adjacent their ends withindentations 23 within which areopenings or perforations .24, .and the bent ends 2| are likewise :provided with registering openings 25.

The .rightehand .bracket .IBQQTShOWH in Fig. .5, is similar in all respects to the left-hand bracket shown in .Fig. .4, except that the flange 2B 'is omitted, thisbracket merely being a flat piece of sheet metal .bent into substantially .L-shaped formandliavingits endportions constructed as already .described in, connection with the lefthand brackets'hown in.Fig.-4. As will be pointed out hereafter, these brackets will be employed in pairs and, as two of them will be used be tween adjacent compartments, it .is only necessary that one .be provided with the partition fianges'Zfl.

It will be obvious that these brackets may be engaged with the stringer elements 12 and I3, which in this term ,of my invention, are rods, by engaging the end ,portions of the brackets thereon, the brackets then beingireely ,slidable upon the .rodslengthwise thereof-so that they may .be placed .in any adjusted positions to provide compartments of various widths. .In order to secure the brackets inplace, I have shown in Figs. 8, 9 and 10 a locking element consisting of an .L- shapedmember .26 .having an .ofiset cam portion 2] thereon and slots 2.8 .cut therein, these slots lying opposite the cam portion 21. .After the brackets have .been ,placed .upon the rods, this member maybe inserted through the openings 24 and-25 with the cam-portion 21 turned in a .direction away from the rods. When the bracket has been moved to the desired position upon the rods, the memberlfi is thengiven apartial turn was .to .cause .thecammember .2-1 to engage the rod andirictionally bind the bracket thereto. .At this time, the edges of the openings .24 and 25 willbereceived in the slots .28 so :that the securing member :26 will .be .held firmly in place. .Thus the :bracketmember will be firmly secured .in the desired position along the rods I2 and I3. It will be understood that this applies to both ends of the bracket member.

In Figs. 11 and 12 of the drawings, I have shown modified forms of fastening elements which may be employed instead of the member 26.

As shown in Fig. 11 of the drawings the opening 25 may be threaded for a machine screw 39 passed through the opening 24 and. threadingly engaged with the opening 25, thus causing the looped end of the bracket to grip the rod I2. In Fig. 12 of the drawings a sheet metal screw 3I is employed in a manner similar to the screw 30 except that this screw will cut its own threads in the opening 25 and frictionally secure the brackets in place.

In Fig. 6 of the drawings I have shown a partition plate 32 designed to be detachably engaged with the flange 29 of the left-hand bracket shown in Fig. 4. This consists of a flat sheet metal member substantially rectangular in shape having tongues 33 and 34 struck therefrom along two sides and slightly displaced from the plane of the plate, so that these plates may be slipped upon the flanges 20 with the latter lying between the body of the plate and the tongues 33 and 34 and frictionally held in place so that this partition plate may be readily positioned upon or detached from the bracket.

It will be seen that the foregoing parts may be readily assembled without the use of special tools to form the completed cabinet which will usually be shipped to the customer in knockeddown condition. In assembling the device, the end sections III and II will be set up and may be secured together in any desired way. The rectangular frames comprising the stringer elements I2 and I3 and the connecting end pieces I4 and I5 will then be secured to these end members by the bolts I 'I and the bolts tightened when this frame has been set at the desired angle. Then, beginning at the left-hand end of a shelf or a row of compartments as shown in Fig. 1, one of the left-hand brackets of Fig. 4 will be positioned adjacent the end member I4 and secured in place by one of the securing members shown in Figs. 8, 11 or 12. Next, one of the right-hand bracket members shown in Fig. 5 may be placed upon the rods I2 and I3 and, when it has been slidably moved along the rods to the desired position to provide a compartment of the proper width, it is secured in place. Immediately adjacent this bracket another left-hand bracket will be secured upon the rods I2 and I3, so that a compartment will be provided between the first left-hand bracket and the two brackets placed in close juxtaposition at a point spaced from the first, this compartment lying between flanges 20 at each side thereof. Thereafter, the brackets will be arranged in pairs along the rods I2 and I3 at desired positions, each pair consisting of a rightand a left-hand bracket, and each pair forming a new compartment with the pair at the left thereof. It will be seen that the body portions I9 and I9 of the brackets form ledges upon which the boxes or packages 29 may rest and that the packages will be prevented from lateral movement by the flanges 20. If these flanges do not serve as sufficient partition members between two adjacent compartments, the members 32 may be placed upon the flanges 20 where desired, thus completely separating one compartment'from another as shown in Fig. 3.

If it is desired to employ the cabinet in connection with unboxed merchandise or loose articles, it will be necessary to close the space between the body portions I9 and I9 of the brackets, and this may be done by the L-shaped or angle plates 35 shown in Fig. 7. These members consist of relatively widesheet metal members bent into angle shape and adapted to rest upon the ledges provided by the body portions I9 and I9 of the brackets and, when put into place, will be confined laterally between the flanges 20. The upper and outer edges may be engaged below the tongues 22 so that they will be held in place. This construction forms a bin open at the top and front into which small articles may be placed, and, if the shelf or row of bins is tipped at a slight angle as shown in the lower portions of Figs. 1 and 2, the capacity of the bins will usually be ample, notwithstanding the fact that they are open at the front. Also the members 35 may be provided with small stuck-out tongues or ears 36 adapted to hold a card or the like to provide a label indicating the particular item contained in that bin or compartment. It will, of course, be understood that the plates 35 may be also used, if desired, when boxes or packages are stored in the cabinet but, in many cases, it will be found that as the compartments may be formed of any desired width, the ledges provided between members I9 and I9 will be sufficient to support the boxes or packages without the use of the members 35. If it is desired to change the width of the compartments it is only necessary to loosen the fastening members 26, 30 or 3I and slide the brackets I9 and It to the proper positions.

(In Figs. 13 and 14 of the drawings, I have shown a further method of securing the brackets to the stringer elements I2 and I3.) In this case, each of the brackets will be provided adjacent their ends with a tongue 38 struck from the bracket and turned rearwardly as shown in Fig. 14 to cooperate with the rearwardly turned end 39 of the bracket to embrace therebetween the rod I2. The parts 38 and 39 are provided with outwardly turned ends 49 and 4! which may be received within an oval or cam shaped opening 42 of a key 43. It will be apparent that when the key is in the position shown in Fig. 13, the ends 46 and 4| of the members 38 and 39 will lie in the narrow dimension of the slot 42 and, therefore, be drawn together to cause the members 38 and 39 to frictionally grip the rod I2 and hold the brackets in place. If, however, the key 43 is turned to a position at right angles to that shown in Fig. 13, the members 40 and 4! will be permitted to spread apart, thus loosening the members 38 and 39 and permitting the bracket to slide freely along the rod I2. The key 43 may be provided with a fingerpiece 44 so that it may be readily turned from one position to another.

In Figs. 15 and 16 ofv the drawings, I have shown a further modified form of my invention which differs from that previously described principally in the form of the stringer elements I2 and I3 and the manner of securing the brackets thereto. It will be understood that the brackets are of substantially the same form as those previously described, as are also the remaining parts of the structure. In this form of my invention the stringer elements I2 and I 3 comprise chan, nel shaped members 45 and 46 which may readily be formed of sheet metal strips bent into U- shaped form. The ends of the bracket members may be turned downwardly and rearwardly as shown at 48 and 49 so that they may be inserted within thesechannels and make a relativelyclose sameness frictional fit therein. ".Thuswthey will normally beheld-in the proper position;althoughtheymay be forcibly movedzalong the channels. ,Iffound necessary-means may be provided 'forsecuring the brackets in place such as binding screwsorthe like, although I have .not disclosed such means herein.

:Itwill be understood :that as shownithe rest of the structure of Figs. 15 and 126 is substantially the same as that shown in Figs. l'to land that the partition plates 32 may be employed asberore. Sometimes, itis found'necessary to provide azplacefor a few boxes or=packages of relatively small size. To provide'for such a-contingencml have shown a basket :member'in'Fig. 117 which maybe employed-forthis purpose. Thismember comprises'a base or bottom portion:5ll suspended by'arms 5i, and the material thereo'f'foldedover attheir upper ends, as shown at52,-so that they may be hung over thepartitions 32to provide an "auxiliary compartment in one of the main compartmentsto hold suchsmall packages.

In Figs. 18 and '19 of the drawings l have shown a further modified form of my invention in which, instead of using-sheet metal'end members and il l, I employ upstanding posts or rods 54 to provide supports for the shelves or 'rows of compartments. These posts may be supported and held together in any desired manner such, for example, as by bands'55. Secured upon these posts are stringer elements "56 which may be channeled or U-shaped 'memberssimilar to the members 48 and 49 shown in Figs. and 16, so that they provide channels to slidably receive :the ends of the bracket members 51.

In this form of my invention, the stringer members 56 are slidably adjustable'vertically on the posts '54 so that they may be secured in any desired position thereon, thus arranging the shelves as close together as-desired. The stringer elements 58 may be provided with rearwardly turned end portions 58 as shown in Fig. 19 to embrace the post 54 and be secured thereto by the fastening elements 59 in a manner'similar to that described in detail in connection with Figs. 8, 9 and'lO. It will be appreciated that with this construction the stringer elements are universally adjustable on the members 54 and will not .be limited to any set positions of vertical adjustment such as might be the case in the form of my invention shown in Figs. 1 and 2 wherein the vertical adjustment of the shelves or rows of compartments will be arranged by the bolt openings and the bolts ll.

While I have illustrated in Figs. 1 and 2 of the drawings a cabinet comprising end supports having a number of shelves, it will be understood that the invention is not limited in this respect. For example, the shelf structure described comprising a pair of stringer elements and hangers mounted thereon as described may be provided for use with existing end supports or cabinets. Also, a single shelf assembly maybe employed upon an ordinary existing shelf to provide a proper place for each one of an assortment of difierent items.

It will also be understood that the stringer elements l2 may be polygonal in cross sectional shape instead of circular as shown or maybe L-shaped or of angle iron construction. The hanger members, while shown as formed of sheet metal, may be cast or molded, or if an ornamental appearance is desired, may be formed of plastic material.

If desired, a tongue -22 'may be placed adjacent 8 the lower endof the hangers t9 and l 9 to cooperate with the uppertongues'fi tolholdcarlzabl or card carrying appropriate indicia so that when the packages seatdirectly upon these hangers, the compartments may be-properlylabeled. If an angle plate 35 (Fig. 7) is employed, this tongue may be easily hammered flat so as to 'be out of the way and, in this event, the card will be placed .on the angle plate and held by the tongues 36. It may here be noted'that the angle plates maybe made as high and as long desired so asto make a bin of any desired'depthgin which event openings would be made in the boiiy of the plate toreceive the tongues 22.

InFig. '20 of the drawings I have shown a. hanger element of modified form to be us'ed between adjacent compartments instead or a pair of hanger members l9 and 19 as previously:described. This member is substantially L-shaped inform comprising the body portionstl and 52 which are relatively wide as compared to th'e hanger members 59 and W and flanges 53 and 6 4 are provided intermediate the side edges 6f the portions Si and 52, so that supporting ledges are provided on each side of the flanges. 'The ends of this member are folded back as'shown at't5sand '56 to receive the stringer elements-and openings M are provided so that it may be secured in place by any of the fastening means shown-in Figs. 8, 11,12 or 14. Also, tongues t8 and t8 are provided as before to cooperate'with onepf the angle brackets shown in Fig. 7 'to support label cards.

Inassernblinga shelf employing these devices, one of the single brackets shown at I9 in Fig.4 would be employed at the left-hand end'ofthe shelithen a number of the double brackets shown in Fig. 20 would be placed along the-stringer-el'ements in spaced relation'as describedand secured thereto to form partitions between the compartments andprovide supporting ledges on each-side of the partition. At the right-hand end'o'f the shelf, another bracket 49 could be employed, this, however, being a right-hand bracket with the flange on the side opposite that shown in Fig.4. If the sides of the bracket lEl are of equal length, it could simply be inverted to form a right-hand bracket.

InFig'Zl of the drawings I'have shown a hanger member which could-be employed to form'stepped shelves or a plurality of shelves of less "depth between a single pair of stringer elements. As shown, this hanger member comprises a plurality of vertical portions 15 and a plurality of horizontal portions l l the ends of the hanger being arranged as before so that they may be readily secured to the stringer elements. Adjacent one edge'ofeach of the portions 10 and H are flanges 12,;this bracket corresponding to the left-hand bracket shown in Fig, 4; The corresponding right han'd bracket would be similarly formed except that the flanges I2 would be omitted. If desired, this stepped hangercould likewisebe made as a double hanger similar to that shown'in'Fig. 20.

In Fig. 22 of the drawings, I have shown an angle plate 13 which may be employed to form the bottom and back of a bin in place of the angle plate shown in Fig. 7. In this instance the angle plate is provided with a front side or .lip 74 which may be of any height desired in order to form-a bin or the desired depth. This will, of course, increase the depth of the bin which is formed over that which :might'be formedwith the plate show-min Fig. 7.

In some instances, it is advantageous to employ a vertical space divider so as to divide a compartment vertically. This is expedient where only a few articles of a kind are kept in stock and will, in effect, make two compartments of the same width where one previously existed. Such a vertical space divider is shown in Fig. 23 and comprises a member I having a looped end 76 by which it may be secured to a stringer element and also provided with a longitudinal slot 17. An L-shaped member 78 is adjustably secured to the member by bolts 19 passing through the slot 77. This memberv F8 is wider than the member 75 so that, while the loop 79 will engage the stringer element at one side of the portion 2| of a hanger member IS, the member i8 will project over the body of the hanger l9 and provide a horizontally extending supporting ledge 80. As shown in Fig. 23 where the hanger i9 is illustrated in dotted lines, the horizontal ledge portion 80 of .1.

this member is provided with a flange 8| which will form a side support for the packages thereon. It will be seen that the horizontal portion 80 of this member will lie substantially parallel to the lower horizontal portion of the hanger member !9 but spaced upwardly therefrom so that an upper and a lower shelf will be provided by the two hangers. It will be understood that it is contemplated to also provide a second vertical space divider similar to that shown in Fig. 23, except that the flange 8i and the member 75 will be in reversed positions, as to left and right, so that this second member may be used at the right side of a compartment while the divider of Fig. 23 will stand at the left.

While I have shown and described some preferred embodiments of my invention, it will be understood that it is not to be limited to all of the details shown, but is capable of modification and variation within the spirit of the invention and within the scope of the claims.

What I claim is:

1. A storage or display cabinet comprising upright end supports, a pair of stringer elements extending between said supports, partition members, means supporting said partition members on said elements in spaced relation for adjustment longitudinally thereof to form compart-' ments of various Widths between the partition members, and means pivotally securing said stringer elements in pairs to said end supports.
