United States PatentCl 3,130,693 BRACKET SUPPORT STRUCTURE Irving W. Shell, 442 W. Wellington, Chicago 14, Ill. Filed Mar. 14, 1962, Ser. No. 179,708 14 Claims. (Cl. 108108) The present invention relates to bracket support structure which, for example, has utility for supporting shelving of the type used frequently in supermarkets for displaying food and other articles either along walls or in the middle of the floor.
The shelving in supermarkets and the like are commonly supported from brackets extending from slotted uprights. Where the shelving is located at a point spaced from the walls of the room, the uprights formpart of ashelf supporting structure where the uprights contact the floor to form points of support for the structure. The uprights are usually provided with forwardly projecting leg units which form additional points of support spaced from the uprights. These leg units commonly have horizontally forwardly extending elevated portions welded to the bottom portions of the associated uprights and terminating in depending front portions which contact the floor. Horizontal frame members extend between the uprights and the front and middle portions of the leg units to provide a stable and rigid support structure.
It is an object of the present invention to provide a bracket support structure of the type described above which is self supporting and is made of small compact and sturdy parts which can be readily assembled preferably without the need for screws, bolts or the like with a minimum of effort. A related object of the invention is to provide bracket support structures as just described wherein the uprights, leg units and frame members are completely separate units before setup of the structure and so can be readily stored in a minimum of space and can be shipped and handled with a minimum of effort. A still further related object of the invention is to provide bracket support structure as just described wherein all of the uprights, leg units and frame members are constructed to form either right or left hand members, thereby reducing the number of different parts out of which the structure is made.
Still another object of the invention is to provide bracket support structure as above described which is of relatively simple and economical construction.
A still further object of the present invention is to provide bracket support structure as described above wherein the elevation of the leg units and the uprights can be readily adjusted at any time.
Another object of the invention is to provide shelf support structure where the shelving comprises spaced brackets having hooked extensions adapted to hook into slots in a pair of uprights, the uprights being designed to accommodate right and left hand shelf assemblies at any one of a number of selected elevations, and including means for tieing together the adjacent shelf assemblies so that the two are maintained at precisely the same elevation even though they are supporting different weights which would normally result in different deflections of the shelf assemblies. A related'object of the invention is to provide a shelf support structure as just described wherein the adjacent shelf assemblies are so designed that they can receive price card receiving moldings which can be mounted in abutment, so that a neat appearance is provided without the use of masking elements for masking the spaces between the moldings.

Referring now to FIGS. 1 and 2, a shelf structure is shown including a self-supporting frame 1 including three laterally spaced identical hollow uprights generally indicated by reference numeral 2. Each of the uprights preferably has a rectangular form (FIG. 13) with relatively narrow outwardly facing walls Za-Za, a bridging side wall 2b extending between corresponding side margins of the outer walls 2a-2a, and narrow, coplanar side walls or flanges Zc-Zc extending inwardly from the other side margins of the outer walls. The confronting edges of the flanges are spaced apart to form a relatively large vertical opening 5. Each of the uprights 2 is adapted to form either a left hand, right hand or intermediate upright. When an upright is placed at one end of the shelf structure, it is oriented so that the bridging walls 2b faces outwardly to form a finished side wall surface.
Each of the outer walls 2a-2a of each of the uprights are identically slotted, there being two types of slots. One type comprises vertical bracket-receiving slots 2d (FIG. 7) which are spaced along most of the height of the upright starting from a position spaced above the bottom thereof. The other type of slots are leg unit-receiving slots generally indicated by reference numeral 2e which are located near the bottom of each of the uprights. One unique and important feature of the invention relates to the relationship of these slots to the horizontally extending leg units 4 and to a locking pin to be described which results in the secure attachment of the leg units 4 to either or both of the outer walls 2a, without the need of bolts or screws.
Each leg unit 4 like each upright 2 is uniquely designed to be used at any position in the shelf structure. The .bottom portions of the uprights and the leg units are tied together by means of specially designed frame members to be described of three different types. One type is a rear or inner horizontal frame member 6 (FIG. 4) which extends between a pair of the uprights and the inner portions of a pair of the leg units; another type is an intermediate horizontal frame member 8 which. extends between a pair of leg units; and a third type is a front or outer horizontal frame member 19 which extends between the outer ends of a pair of the leg units. The front frame members 10 are designed to receive a shelf and price card receiving molding strip 12. A bottom shelf 14 is held in place by the molding strip 12 in a manner to be described.
Extending between the outer portions of each pair of uprights is a vertical backing panel 16. The shelf structure is adapted to support shelving on either or both the front and rear sides thereof as illustrated by the dotted configuration of shelving shown in FIG. 2. When shelving is supported from both the front and rear sides of the shelf structure, the structure has a perfect longitudinal symmetry as illustrated in FIG. 2. In such case, a pair of the panels 16 are used which are respectively adjacent the outer walls 2a-2a of the uprights 2. The structure is so designed that the vertical panels 1616 are held securely in place by the wedging action of the bottom shelves 1414 and the other shelves to be described.
The shelf structure supports lower and upper shelf units indicated by reference numerals 18a and 18b, respectively. The shelf structure illustrated in the drawings is a pyramid type where the lower shelf units 18a are wider than the upper shelf units 18b. Each shelf unit includes a pair of end brackets war-26a or 2ilb20b having a. length corresponding to the width of the associated shelf unit. Horizontal shelf supporting channel members 22 and 24 are welded or otherwise secured between each pair of end brackets, there being illustrated three members 22 spaced rearwardly of the outer ends of each shelf unit at the same elevation and a front frame member 24 which is at a lower elevation than the frame members 22. Each of the end brackets 20 is a sheet metal stamping having a pair of vertically spaced rearwardly extending hooked extensions 21 and 23 which are substantially identical to the design of the hooked extensions of the bracket disclosed in copending application Serial No. 835,469, filed August 24, 1959 The upper hooked extension 21 hooks upwardly and the bottom hooked extension 23 hooks downwardly. These hooked extensions are adapted to extend into and interlock with the defining walls of a pair of the bracket-receiving slots 2d of the uprights. The latter upright slots preferably have a width which is slightly greater than twice the width of the hooked extensions of the brackets so that two brackets can be placed in the same slot 2d. The end brackets 2t)a-2tla or 2tl b2tb of each of the shelf units are spaced apart a distance such that the hooked extensions thereof extend respectively into the right half of the slot 2d of a left hand upright and the left half of a slot 2d of a right hand upright. In this way, contiguous shelf units can be supported at the same elevation in contiguous relation sharing the same slot 2d of a common upright, such as the intermediate upright shown in FIG. 1. Means to be described are provided for tieing together the shelf units sharing a common slot 2d so that two shelf units will have the same elevation even when they support different weights causing different deflections of the end portions of the shelf units.
The end brackets Zita-2hr: or 2t3b2tlb and the front frame member 24 of each shelf unit are designed to receive a shelf supporting and price card receiving molding strip 12 which is similar in many respects to the molding unit 12 used with the bottom shelf 14. Due to certain design features of the shelf units to be described, the molding strips l2- l2' of a pair of shelf units supported at the same elevation can be brought into abutment to form an almost invisible joint therebetween. Each molding strip retains the front edge portion of a shelf 26a or 26b, the rear edge thereof being braced against the associated vertical panel 16 to aid in holding the panel securely in place.
Each of the leg units and the uprights have elevation adjusting means to be described secured to the bottoms thereof and by means of which the elevation of the shelf structure can be readily adjusted at any time. The elevation adjusting means includes adjustable headed screws 30 (FIG. 7) to which access may be had through the aforementioned opening 5 in the side of each upright and through an opening 4:: in each of the leg units (FlGS. 3 and 12).
To present a neat appearance, the various exposed edges of the shelf structure are covered over by various cover units. For example, the outer edges of all of the molding strips 12 associated with the shelf units are covered by identical individual snap-on cover units 32 having a centered hooked extension 32 which can snap into a slot 25 in the forward end portions of any end bracket 20a or 26b. Side covers plates 33-33 have hooked extensions 3333 which snap into slots in the sides of the leg units to cover the open sides of the leg units and also the raw edges of the lower molding strips 12. Front cover plates 35 extending between each pair of leg units have hooked extensions 3535 which snap into slots 4g in the forward walls of a pair of leg units to cover over the spaces between the lower shelf 14 and the floor. Top plates 37 are provided which extend between and rest upon the tops of each pair of uprights and overlap the panels 16.
When it is desired to adjust the angle of inclination of the various shelf units 13a and 18b, individual attachment members 39 to be described (FIGS. 19 and 20) are interposed between the uprights 2 and the hooked extensions 21 and 23 of the various brackets 2% and 2%.
Now that the elements of the frame structure of the present invention have been broadly introduced, the unique structural features thereof will now be described in detail.
Refer now more particularly to FIG. 13 which shows the details of the leg unit-receiving slots 2e in the bottom portion of each of the uprights 2. As there shown, each of the outer walls 2a of the upright have two vertically spaced pairs of horizontally spaced slots 2e-1 and 2e-1 and 2e2 and 2e-2 located adjacent to the side margins of the wall. The upper portions of the upper pair of slots 2e-1 and 22-1 intersect a pair of laterally facing and horizontally aligned opening 2f2f respectively formed at the outer margins of the bridging wall 221 and in the adjacent flange 20. As will appear, the aligned openings 2f-2f are adapted to receive a pin 40 which, in accordance with the preferred form of the invention, carries out two important functions, namely locking the associated leg unit in place on the upright and supporting the rear horizontal frame member 6 on one or both sidesv of the upright.
Each of the leg units comprises a channel member having a horizontally extending elevated portion 4b with laterally spaced vertical side Walls 4b-1 and 4b-1, and a bridging top wall 417-2, and a depending floor-engaging portion 4c having vertical side walls 40-1 and 40-1 in the same plane as the side walls 4b-1 and 4b-1, and a front wall 4c2 which inclines downwardly and rearwardly to form a tapered leg. The contiguous edges of the side walls 411-1 and 4c-1 are welded together to form a sturdy, integral, bracing leg structure. When each of the bracing legs are mounted in place, the outer surfaces of the side walls 4b-1 and 40-1 are respectively flush with the sides 2b and 2c of the associated upright 2.
A hook-forming insert member 4d is welded or otherwise secured to the inside of the rear portion of each leg unit, the insert member 4d having two vertically spaced pairs of horizontally spaced depending hooked extensions 4d-1 and 4d-1 and 4d-2 and 4d2 which are respectively adapted to extend into and interlock with the defining walls of the correspondingly spaced slots 2e-1 and 2e-1 and 2e-2 and 2e-2 in the bottom of the associated upright. The height of each of the hooked extensions 4d1 and 4d-2 is slightly less than the height of the corresponding upright slots 26-1 and 2e2 but, due to the slots forming the necks of the hooked extensions which contact the bottom edges of the associated upright slots, the hooked extensions in their mounted positions occupy only the lower portions of the upright slots 2e-1 and 2e-2. The upper edges of the upper hooked extensions 4d-1 and 4d-1 are then immediately below the lower level of the laterally facing openings 2f2f. Consequently, when pin 40 is press-fitted within the aligned openings 2f-2f of the upright, the pin will overlie the upper edges of the upper hooked extensions 4d1 and 4d-1 to prevent removal of the hooked extensions from the associated upright slots. For reasons to be explained, each of the pins 40 has a length substantially greater than the width of the associated upright, so that the pin can be selectively centered in the aligned openings 2;f2f where they project laterally beyond both sides of the upright (FIG. 14) or, alternatively, so that the pin is flush with the outer side of the upright and projects way beyond the inner side wall or flange 2c thereof (dotted line position of FIG. 14).
Each leg unit has a number of slots formed therein for detachably receiving the hooked extensions of various elements of the frame structure. Thus, pairs of slots 4e4e are positioned at different points along opposite sides of the horizontally extending portion 4b of each leg unit. Each of these slots extends through one of the corners of the leg unit at the intersection of the bridging top wall 4b2 and a side wall 4b1 thereof. Two pairs of the slots 4e-4e are located adjacent the rear of the leg unit, two pairs of the slots are located at the central portion of the leg unit, and two pairs of the slots are located contiguous to the front end of the leg unit. The side cover plates 33-33 have hooked extensions which extend into the forwardmost of the rear pairs of slots 4e and the rearwardmost of the front pairs of slots.
Each leg unit further has a pair of horizontally aligned pin-receiving openings 4f4f at the juncture of the side walls 411-1 and 4c-1. A pin 40 is press-fitted within the aligned openings 4f-4f of each leg unit so that it projects equally beyond both sides of the leg unit where the latter is associated with an intermediate upright 2, and so that it projects only beyond the inner side of the leg unit where the latter is associated with an outer upright 2. The front wall 4c-2 of each leg unit is provided with a pair of vertically spaced slots 4g-4g which receive the hooked extensions of the front cover plate 35.
The portions of the pins 40 projecting beyond the sides of the uprights 2 and the leg units 4 act as supports for the rear and front frame members 6 and 10 which extend between contiguous pairs of the uprights and the leg units. Each rear frame member 6 has a horizontal shelf support wall 6a whose rear portion restson the upper surface of a pin 40, a rear upstanding bracing wall 6b and a front depending bracing wall 60. The opposite ends of the depending wall 6c terminate in a pair of projecting, depending hooks 6d-6d which are adapted to extend into the confronting, rearwardmost leg unit slots 4e-4e of a contiguous pair of leg units. When the hooks 6d6d are fully in engagement with the defining walls of the slots 4e-4e, the rear portion of the shelf support wall 6a of the frame member 6 will rest upon the projecting portion of a pair of the pins 40 and the shelf support wall 6a will be level with the bridging top walls 4b-2 and 4b-2 of the leg units involved. The frame member walls 6a and 6b respectively will be in contact with the sides of the contiguous pairs of upright and leg units involved to brace the structure in a lateral direction to aid in forming a rigid frame structure.
The intermediate frame members 8 extending between the middle portions of a contiguous pair of leg units are channel members having a pair of depending hooked extensions Sa-Sa projecting from the ends of the flanges thereof and respectively extending into a pair of the slots 4e4e in the leg units.
Each of the front or outer frame members 10 extending between a pair of the leg units has a top support wall 10a which terminates at the front in a depending wall 10b which, in turn, terminates in a forwardly and upwardly inclined lip 100. The lip 10c and the depending wall 1012 together form a channel for supporting the molding strip 12 to be described. Each front frame member 10 has a rear depending Wall 10d which has at the opposite ends thereof a pair of projecting depending hooked extensions Tile-10a adapted respectively to extend into the forwardmost confronting slots 4e-4e of the associated pair of leg units. When the hooked extensions 10e10e are fully in engagement with the defining Walls of the slots 4e4e, the forward portion of the support wall 10a rests upon the projecting end portions of a pair of pins 40 at the forward ends of the pair of leg units involved. The support wall 10a in the fully mounted position of the frame member 10 is at an elevation slightly below the top surfaces of the bridging walls 417-2 and 4b2 of the associated pair of leg units.
Since the leg units have corresponding slots 4e on both sides thereof, each leg unit is adapted to support frame members 6, 3 and 10 on either side thereof.
As previously indicated, each of the front frame members 10 is adapted to support a shelf holding and card receiving molding strip 12. Each molding strip comprises a downwardly and outwardly inclining front wall 12a which forms an open ended channel into which a price card may be slipped. The molding strip further has a depending flange 12b which enters the channel formed by the channel-forming walls 10b and of the front frame member 10, as best shown in FIG. 7. The molding strip further has a pair of rearwardly extending and vertically spaced shelf-receiving wall extensions 12c-12d. These two walls form a channel for receiving the forward edge of the shelf 14. The top surface of the bottom wall extension 120, the shelf support wall 6a of the rear frame member 6, and the intermediate frame member 8 are all in the same horizontal plane so that the shelf 14 will be horizontal.
As previously indicated, the uprights and the leg units are provided with elevation adjusting means including adjustable headed scerws 30. Each of these screws has a threaded shank 30a having a screwdriver-receiving slot in the top thereof, and a floor-engaging head 30b at the bottom thereof. The threaded shank of each screw threads through a threaded opening 41 in a horizontal plate assembly 42 which carries the bottom end of the associated upright or the floor-engaging portion of 4c of the associated leg unit. Each of the plate assemblies 42 comprises a base plate 43 having upwardly extending lips 43a-43a and 43b-43b on the opposite sides thereof.
The ends of the lips 43a and 43b are spaced from each other to provide clearance slots for the passage of the vertical walls of the uprights and the leg units. When positioned beneath one of the uprights, the outer upright walls 2a-2a extend on the outside of the base plate 43 as shown in FIG. 17, and the bridging wall 21) and the planges 2c2c extend between the slots defined by the spaced ends of the lips 43a and 43b of the base plate To adapt each plate assembly 43 for use on the bottom of a leg unit, an inner plate member 44 is secured as by welding to the top of the base plate 43, which plate member has a pair of parallel upstanding lips 44a-44a along a pair of opposite sides thereof, the lips 44a44a being spaced inwardly from the lips 43b43b of the base plate 43 to form narrow channels for receiving the side walls 4c-1 and 40-1 of the forward depending portion 4c of each leg unit, as shown in FIG. 16. The outer wall 4c-2 of each leg unit in such event passes around the outer edges of the lips ida-44a of the inner plate member 44.
The elevation of the leg units is varied by passing the shank of the screwdriver through the opening 4a in the top of each leg unit, inserting the end of the screwdriver into the screwdriver-receiving slot at the top of the associated screw 30 and turning the same. The elevation of the screw uprights is adjusted by passing the shank of the screwdriver through the vertical opening 5 in each upright, inserting the end of the screwdriver into the slot in the top of the associated screw, and turning the same.
The shelf units 18a and 18b previously briefly described have two important unique features which relate to the design of the end brackets 20 thereof and their relationship to the shelf holding and price card receiving molding strips 12'. These features relate to support of contiguous shelf units at the same elevation. Frequently, the Weight supported by such contiguous shelf units is sufliciently different that deflection of one shelf unit will be somewhat different than the other. In order to tie two shelf units together so that the two remain at the same elevation independently of the weights of the articles supported thereby, the end brackets Zita and 20b of the shelf units are provided with horizontally extending and aligned slots 2525. Extending through the slots 2525 of confronting end brackets 2a2tla or Nib-20b is a flat key member 27 shown most clearly in FIG. 10. Each key member has a narrow shank portion 27a with a width approximately equal to that of the slots 25 and a length approximately equal to the spacing between the outer faces of the end brackets. One end of the shank portion 27a of each key member terminates in a laterally extending wing 27b having a length greater than the slots 25 and adapted to be grasped and turned by an operator, and the other end terminating in a wing 270 in the same plane as the wing 27b and having a length no greater than the length of the key-receiving slots 25. In one position of the key member as shown in FIG. 11, the shorter wing 270 can be passed through the aligned key-receiving slots 25 to bring the handle forming wing 27b against the outer surface of the adjacent bracket. Then, the key member can be turned approximately 90 where the contiguous bracket becomes wedged in the space between the wings of the key member, as shown in FIG. 10. The two shelf units are thereby held at the same elevation through the medium of the key member.
In accordance with another feature of the present invention, the end portion of each of the brackets 20a or 2017 has a cut-away portion providing a depressed upper edge 26. One end of each front frame member 24 of each shelf unit is welded or otherwise secured around the forward edge of an end bracket Ztla or 20b, the upper end thereof terminating short of a shoulder 27' on the bracket to provide a space or channel between the rear edge of the frame member 24 and the shoulder 27. This channel receives a depending lip or flange 12a on the rear of the associated shelf holding and price card receiving molding strip 12', the defining walls of the channel retaining the molding strip on the frame member 24 and enabling the molding strip of contiguous shelf units to be brought into abutment. Each molding strip 12' has a pair of vertically spaced rearwardly extending wall extensions 12c and 12d which provides a channel for receiving the forward edge portion of the associated shelf 26a or 26b. The upper surface of the wall extension 12c is level with the top surfaces of the shelf unit frame members 22 so that the shelf is supported in a perfectly horizontal position within the channel formed by the wall extensions 12c and 12d. Each molding strip 12' further has a downwardly and forwardly projecting portion 121) which forms an open ended channel into which a price card may be slid as in the case of the molding strip 12. Also, the molding strip 12' has a depending wall or flange 122 which abuts against the outer frame member 24.
If it becomes desirable to support the shelf units at an angle to the horizontal, this may be readily achieved by means of a simple insert member 39 (FIGS. 19 and 20) which is insertable between each upright and the end bracket of a shelf unit. This insert member may be a fiat sheet metal stamping having a pair of rearwardly extending hook extensions 51 and 53 corresponding to the hooks 21 and 23 of each of the brackets 20a or 20b. A pair of hook-shaped slots 52 and 54 are respectively formed in the front edge of the insert member which conform to the shape of the hooked extensions 21 and 23 at the rear end of each of the brackets 20a or 20b and are spaced along a line inclined at an angle corresponding to the desired angle of inclination of the shelf units. It can thus be seen that a pair of insert members 39-419 can be mounted in place between a pair of uprights 2-2 and end brackets of a shelf unit by inserting the hooked extensions 51 and 53 of a pair of insert members into the slots of a pair of uprights and the hooked bracket extensions 21 and 23 of a pair of end brackets into the correspondingly sized slots 52 and 54 of the insert members.
Thus, the present invention has provided a very simple and economical knock-down frame structure with a minimum of different parts which can be readily assembled and disassembled without the need for any screws, bolts and the like.
It should be understood that numerous modifications may be made in the preferred form of the invention described above without deviating from the broader aspects of the present invention.
