y FA L/X 206% W MM 4 rraeA/H United States Patent z 15 Claims. (31. 108-108) The present invention relates to improvements in shelves, especially for storing and exhibiting merchandise in stores.

Such shelves are generally composed and assembled of vertical posts or standards on which a back wall is mounted, and of shelf boards which are supported on the standards by brackets. Depending upon the different types of construction of the shelves, these brackets may be either secured to the back wall or directly to the standards. Prior to this invention, these standards usually consisted of iron and were therefore very heavy and hard to manipulate in shipping and also in the assembly of the shelves. Furthermore, a quantity production of such iron standards was possible only if they were made of certain standard lengths. Consequently, if in particular instances iron standards of other lengths were required, they had to be specially made, their cost was therefore much higher, and they had to be ordered a long time prior to the erection of the shelves. If such standards were to be used for erecting shelves with shelf boards on both sides, the standards also had to be specially provided with apertures on opposite sides for the suspension of brackets for supporting the shelf boards. Another disadvantage of these known shelf structures was that their back walls had to be provided with strong wooden frames or at least with strong wooden or iron struts in order to secure them to the standards by bolts, straps, or the like or to give these back Walls a sufiicient lateral stability. Many of the known shelf structures also do not permit the brackets for supporting the shelf boards to be adjusted to different elevations.

In order to segregate different kinds of merchandise from each other or to prevent the stacked items from falling over laterally, shelves are often subdivided by means of wire frames or partitions which are applied upon the shelf boards. This has in the past been done by providing the shelf boards near their front and rear edges with holes into which the free ends of these frames may be inserted. One of the disadvantages of this manner of mounting the frames is that, if the shelf boards consist of metal, small burrs very often remain on the edges of these holes and that bags containing merchandise may be ripped by the burrs on the unused holes when these bags are placed on or removed from the shelf boards or that threads or stitches of textile goods may be caught by such bunrs and the goods be damaged. Furthermore, since these frames or partitions can be adjusted to different positions only in accordance with the location of the holes in the shelf boards, the compartments which are thereby formed on the boards may not have the required size so that either valuable shelf space may be wasted or the merchandise will not be properly held by these partitions.

It is an object of the present invention to provide a new shelf structure which eliminates all of the mentioned disadvantages of similar shelves according to previous designs, may be easily transported, manipulated and assembled, easily adjusted to any desired height, and easily subdivided into sections or compartments of any desired sizes.

These as well as numerous other features and advantages of the present invention will become more clearly apparent from the following detailed description thereof 3,316,863 Patented May 2, 1967 which is to be read with reference to the accompanying drawings, in Which- FIGURE 1 shows, partly in section, a side view of a shelf according to the invention which is composed of vertical standards, bases for these standards, brackets projecting from one side of the standards for supporting shelf boards, and a rear wall;

the invention consists of a base 1 While the standard 2 according to FIGURE 1 is provided with shelf-board brackets which projects only toward one side thereof, FIGURE 2 shows the same standard supporting such brackets which project toward opposite sides. In this event, the standard 2 may also support a double back wall 4a and 4b.

The standard 2 according to FIGURES 1 and 2 has a substantially H-shaped cross-section, as shown in FIG- URES 3 and 4, and consists of

side walls

5 and 6 and a central web 7 which connects these two walls. The

side walls

5 and 6 are provided at their front and rear ends with short, outwardly projecting flanges 3 and inwardly projecting flanges 11, and at equal distances from these ends with longer, outwardly projecting flanges 9, which are provided with hooked-shaped outer ends 10 which are bent in the direction toward the flanges 8 and are preferably curved slightly inwardly. The

side walls

5 and 6 are further provided with inwardly projecting flanges 12 which extend parallel to and are spaced at a short distance from the end flanges 11 and have a length substantially equal to the length of these end flanges.

Due to the particular shape of the standard 2, the "back wall 4 may be inserted therein from the front and be clamped between the

flanges

8 and 9, 10. The back wall 4 according to FIGURE 3 consists of stamped sheet metal and its flat side may, if desired, be perforated. Its lateral edge 13 is bent over at a right angle and inserted between the

flanges

8 and 9, 18. For reinforcing the sheetmetal plate 4, its upper and lower ends are bent over so as to form flanges 14 which are provided with recesses 15 into which the hook 10 on flange 9 engages.

According to FIGURE 4, the back wall 4 consists of a panel, for example, of plywood, compressed Wood chips or the like, or of plastic or the like. This panel may also be employed in connection with the same standard 2 as previously described, but its rear side must for this purpose be provided with a groove 16 into which the hook 10 engages. This panel 4 is inserted between the

flanges

8 and 9, It} in the same manner as the sheetmetal plate 4 according to FIGURE 3, and the lateral side of its outer surface then also engages with the inner side of flange 8. The

opposite flanges

11 and 12 on the

side walls

5 and 6 of the standard are provided for holding a strip 17 preferably of steel plate, which may be inserted between these flanges and serves for the purpose of reinforcing the standard and also for supporting the brackets 3 which may be hooked into any of the elongated apertures 18 in the strip 17 which may be spaced at any desired distances from each other. As illustrated in FIGURE 5, these apertures 18 in the strip 17 may also be cross-shaped.

The standards 2 according to the invention may be made of light metal which also has the advantage that the visible part thereof may be either polished or eloxadized. Due to the steel strip 17 which is inserted between the

flanges

11 and 12 on the

walls

5 and 6 of each standard 2, this standard has a solidity equal to that of the steel standards which were previously used for storage shelves.

As previously indicated, the standard 2 may be made of any desired length or of long standard lengths and may then simply be cut down to the particular length as desired. Due to the two-chamber structure of each standard 2, it is possible to insert the projecting end of either one or two cast bases 1 into its lower end, depending upon whether the brackets 3 for supporting shelf boards should project only toward one side, as shown in FIGURE 1, or toward opposite sides of standard 2, as shown in FIGURE 2. The upwardly projecting end of each of these bases which is inserted into the lower end of one or the other of the two chambers of standard 2 is made of a sufiicient length and fits so tightly into the respective chamber that there is no need 4 either to weld or bolt the standard and the base or bases to each other.

FIGURES 6 to 8 illustrate brackets which may be hooked into the cross-shaped apertures 18 in a steel strip 17 as shown in FIGURE 5. Each of these brackets has a horizontal supporting surface 19 which is secured to the upper side of a vertical reinforcing plate 20 and is provided with holes 19a into which short studs on the lower side of a layer 1% of rubber or soft plastic may be inserted for supporting and cushioning a glass plate which serves as a shelf board. The rear upper end of each bracket is provided with a T-shaped hook 21 which may be inserted into one of the apertures 18 in the steel strip 17 when the bracket is turned at an angle of 90 to the position as shown in FIGURE 7. When the bracket is thereafter turned back to its normal position, the neck 22 of the T-shaped hook 21 rests on the lower edge 23 of the aperture 18. Underneath the T-shaped hook 21, the rear end of the bracket is provided with a recess so as to form a holding projection 24 which, when the hook 21 is inserted into one aperture 18 engages into the next lower aperture 18 and abuts against the upper edge 25 of this lower aperture.

As illustrated particularly in FIGURE 10, each of the brackets according to FIGURE 9 is further provided with several lateral tablike projections 30 upon which the shelf board or boards may be placed. A very simple manner of producing these projections 30 consists of punching them out of the plate 20. The upper ends of these tabs 30 may be bent slightly outwardly. As illustrated in FIG- URE 21, these projecting tabs 32 may also be used for hooking additional supporting angles thereon. Each of these angles consists of a vertical part 71 and a horizontal part 72. The vertical part 71 is provided with a recess 73 of a width equal to that of the tab 32, while from the horizontal part 72 a pair of triangular pointed prongs 74 are punched out and bent vertically upward, thereby leaving corresponding apertures in the horizontal part 72. The inner edges 76 of prongs 74 extend vertically, while the outer edges 77 extend at an oblique angle to the upper surface of part 72.

If after the

angles

71, 72 have been hooked over the tabs 32, a shelf board of wood or a similar material is to be mounted thereon, such a board may be placed upon the prongs 74. A light blow upon the upper side of the board will then suffice to drive the prongs 74 fully into its lower side. The shelf board then rests flat on the upper surface of the horizontal angle part 72 and it is prevented from sliding thereon in any direction by the prongs 74. The corresponding parts of the shelf as previously described may be easily packed together and shipped separately from theother parts, and all of the parts may be very easily and quickly assembled.

As illustrated in FIGURE 11, the bracket may also carry a raillike tag holder 37. For this purpose, the side wall of a supporting member 33 is clamped behind the projecting tabs 32 and its rear end is bent downwardly substantially at a right angle for abutting against the rear edge of a shelf board or for being secured thereto. The front end of the supporting member 33 is likewise bent downwardly substantially at a right angle, and near its front edge 34 it is provided with a corrugation 35 so as to form a recess in its upper surface. The lower front end 36 of the supporting member 33 is bent over toward the rear so as to form a hook.

This supporting member 33 permits the tag holder 37 to be clamped thereon in the manner as shown in FIG- URE 11. The tag holder is for this purpose provided on its rear side with hook-shaped

projections

38 and 39. The upper hook 38 is adapted to engage into the recess which is formed by the corrugation 35', while the lower hook 39 is snapped over the lower bent-over end 36 of the supporting member 33.

FIGURE 12 illustrates a partition for dividing the space on a shelf board into separate sections or compartments.

This partition consists of a frame 40, a lower horizontal rod 41 and vertical rods 42. As shown more clearly in FIGURES 13 and 14, each foot 43 and 44 of this frame has a horizontal pin-shaped

arm

45 and 46, respectively, by means of which the partition 40 to 44 is clamped tightly upon the shelf board 47 which in this case is illustrated as consisting of a sheet-metal plate. The pinshaped arm 45 fits into a groove 48 in a tag rail 50 which is clamped over and covers the front wall 51 of the shelf board 47, while the pin-shaped arm 46 fits into a groove 49 in a clamp 52 which is clamped over the rear wall of the shelf board 47.

FIGURE 17 illustrates a modification of the manner of securing a framelike partition as shown in FIGURE 12 to a shelf board. In this case, the groove 48 for receiving the pin-shaped arm 45 on the foot 43 of the partition is not provided in the tag rail 50 but in the shelf board 47 which therefore differs slightly from the shape as shown in FIGURES 12 and 13. According to this modification of the invention it is possible to secure the framelike partition to a shelf board even if the latter is not provided with a tag rail, namely, by clamping it directly upon the shelf board.

The framelike partition 40 according to FIGURE 12 may also be modified so as to serve as a support for additional partitions or the like. As illustrated in FIG-

URES

15 and 16, a pair of small

angular brackets

54 and 55 are secured in vertical alignment to the two

horizontal rods

53 and 41 of the frame. Each of these

brackets

54 and 55 has an angular cross section as shown in FIGURE 16, and its arms together with the

horizontal rod

53 or 41 define two

U-shaped recesses

56 and 57 which extend at right angles to each other. The corresponding recesses 56 and 57 of both

brackets

54 and 55 are adapted to receive the edges of partitions, not shown, which may be inserted therein from above.

A modification of the means for holding additional.

partitions on the frame 40 is illustrated in FIGURES 18 and 19. These holding means consist of a pair of

vertical brackets

58 and 59. The opposite ends of bracket 58 are secured to the

horizontal frame rods

41 and 53 so that the part of this bracket intermediate these rods projects from and extends substantially parallel to the plane of frame 40. Theother bracket 59 is laterally spaced from and extends parallel to the bracket 58 and it is likewise secured to the

horizontal frame rods

41 and 53. The upper and lower ends of this bracket are, however, additionally bentso as to form U-shaped parts 60 and 61 behind which a partition may be inserted so as to extend along and parallel to frame 40, while another partition which extends at right angles to the plane of frame 40 may be inserted into the gap 62 between the two

brackets

58 and 59.

A further modification of the means for holding additional partitions on the frame 40 according to FIGURE 12 is illustrated in FIGURES 22 and 23. These holding means consist of a flat element 78 which may consist, for example, of plastic and is provided on its front side near its upper and lower ends with two forwardly projecting

horizontal strips

79 and 80 which are provided with a plurality of corresponding recesses 81 in vertical alignment with each other and laterally spaced from each other. The upper end of the holding element 78 is bent over toward the rear so as to form a hook 82 for hanging the holding element over the upper horizontal bar of frame 40, as shown in FIGURE 12. Near its lower end, the holding element 78 is provided on its rear side with a projecting strip 83 which, when the holding element is hooked over the frame 40, passes between the feet 43 and 44 thereof directly underneath the lower horizontal bar 41 and then locks the holding element against any unintentional removal in the upward direction. The holding element 78 may be further provided with a low flange has a width ridgelike strip 84 above the strip 83 for bracing the holding element on the vertical frame bars 42.

In order to increase the solidity of the shelf boards and to facilitate the operation of packing them for shipment, it has been found advisable to provide their free ends 63 with several corrugations, as shown in FIGURES 17 and 20. These corrugations reinforce the shelf boards and also permit two boards to be packed together without any intermediate packing material by being placed inversely to each other so that the corrugations 63-of both boards engage with each other and thereby also prevent the boards from shifting in their longitudinal directions relative to each other within their common outer packing material.
