No. 755,940 Int. Cl. A47f 5/00 U.S. CL 211-150 8 Claims ABSTRACT OF THE DISCLOSURE A shelf formed of a single sheet with various portions of the shelf so arranged that the shelf has substantial structural rigidity when supported at the ends thereof. The shelf can be divided by means of removable dividers which are locked in place when in position.
BACKGROUND OF THE INVENTION This invention relates generally to shelves and dividers of the type used to display merchandise Vfor point of purchase sale. The shelves can be secured to wal] standards or island frames and the shelves are generally movable so that various display arrangements can be created. While the shelves must have considerable rigidity in order to support heavy merchandise, it is also desirable that it have a light and airy feeling so that the principal display will be the merchandise and not the shelf. Since the shelves, at various times, are used for displaying different merchandise7 the shelves should also be sufficiently versatile to accommodate and separate a variety of merchandise and dividers are useful for this purpose.
SUMMARY OF THE INVENTION Generally speaking, in accordance with the invention, a metal shelf is fabricated of one piece construction and includes reinforcing portions at all sides which are so designed as to impart structural rigidity without detracting from the light and airy appearance. With the one piece construction, the cost of the shelf is substantially reduced. The surface of the shelf is perforated and removable dividers can be selectively and randomly mounted thereon in engagement with the perforations and means are provided to secure the dividers in position to prevent inadvertent removal.
Accordingly, it is an object of this invention to provide a shelf of improved construction.
Another object of this invention is to provide a sheet metal shelf of one piece construction that incorporates reinforcement at all sides while being supported at the ends thereof.
A further object of the invention is to provide a perforated shelf with an improved removable divider.
Still another object of the invention is to provide a removable divider for a shelf which locks to the shelf to prevent inadventent removal thereof.
Still other objects and advantages of the invention will in part be obvious and will in part be apparent from the specification.
The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the invention will be indicated inthe claims.
BRIEF DESCRIPTION OF THE DRAWINGS For a fuller understanding of the invention, reference is had to the following description taken in connection with the accompanying drawings, in which:
FIG. 1 is a top plan view of a shelf and divider constructed in accordance with a preferred embodiment of the instant invention;
3,508,565 Patented Apr. 28, 1970 ICC DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings, a shelf 11 is supported by any suitable means such as standards 12 which may be secured to a wall 13. The shelf is sheet metal and is preferably provided with a plurality of perforations 14 which are preferably positioned in a geometric orientation. The `base 15 of the shelf is generally flat and the front Wall 1'6 extends upwardly at a preferred angle of substantially The top edge of front wall 16 is preferably a rolled edge 17 which nishes off the edge and also adds to structural rigidity. At the rear edge of the shelf, a rear flange 18 extends downwardly at an angle of less than 90 to strengthen and render rigid the rear edge of the shelf. Each side edge of the shelf is provided with a side flange 19 which extends downwardly at substantially 90 from base 15. Side flanges 19 may taper as shown in FIG. 2 to be of lesser width at the front edge of the shelf than at the rear edge.
Each of the four edges of the shelf includes an integrally formed flange or side which reinforces the base to such an extent that additional reinforcing members are not necessary. In order for the shelf to operate satisfactorily, each edge must be provided with an integral flange so that maximum strengthening will be accomplished by the four flanges. The side and rear flanges extend below the base with the rear flange defining an angle of less than 90 while the front flange preferably extends upwardly to accomplish the purpose of also providing a front for the shelf.
In mounting the shelf to standards 12, a plate is secured to each side flange 19 and includes any suitable type of hook 22 which will engage in the slots 23 in standard 12.
In the embodiment disclosed, the shelf may be tilted to several positions. A slot 24 in side flange 19 receives a headed pin 25 secured to plate 21. A slot 26 having Several detent positions 27 is provided in plate 21. Slot 26 lies on a radius `with respect to the center of pin 25. A headed pin 28 is secured to side flange 19. With such arrangement, the position of side flange 19 and thus the entiie shelf with respect to each plate 21 may be adjusted and a tilted position of the shelf is shown in phantom in FIG. 2.
While the construction of the shelf, per se, appears relatively simple, the utilization of the four flanges or sides located along the four side edges permits of a rigid construction formed from a single sheet. If tilting of the shelf were not desired, hooks 22 could be formed as part of side flanges 19.
In order to increase the usefulness of this shelf a plurality of dividers 31 are provided which engage in the perforations 14 on the base of the shelf. Divider 31 is an elongated element having a substantially U-shaped cross sectional configuration as shown in FIG. 4. The base 32 of the U forms the top of the divider and is smooth and attractive while the legs 33 of the U form the divider walls. The outer ends of legs 33 are turned outwardly to form flanges 34 and secured at spaced intervals. to flanges 34 are clips 35. Each clip has a hook end 36 extending therefrom for engagement with the bottom surface of the base 15 of the shelf. In the embodiment shown in FIG. 2, two clips 35 are provided and divider 31 is randomly positioned on the shelf by in- 3 setting hook ends 36 through selected perforations 14 and sliding the divider in a forward direction to cause the hook ends to engage under the shelf.
A locking device indicated generally at 41 passes through one of perforations 14 to limit the reverse movement of the divider to prevent the divider from being unhooked. The locking device is in the form of an elongated plate 42 extending upwardly between the legs 33 of the divider. Plate 42 extends through the base of the U 32 which defines the top of the divider and has a bent over lip 43 which prevents the freely movable plate from dropping down through the divider. Plate 42 extends below the divider and is provided with a lip 44 which will engage 4beneath one of flanges 34 to prevent plate 42 from being pulled out of the divider.
As shown in FIG. 2, plate 42 and clip 35 substantially completely fill the width of a perforation 14 to thereby prevent movement of the divider. With the orientation shown in FIG. 2, divider 31 must be moved toward the left in order to disconnect the divider. Such movement is prohibited by engagement of the left edge of plate 42 with the edge of perforation 14 through which it extends and thus the divider is locked in position.
In order to move the divider, lip 43 is physically grasped and the plate is thereby lifted to pull the plate out of the perforation so that the divider may be moved toward the left to unhook clips 35 from beneath the base of the shelf.
When positioning the divider on the shelf, the weight of plate 42 will normally cause it to project downwardly below the divider as limited by clip 43. When clips 3S are threaded into the perforations, plate 42 will be positioned over a solid portion of base which will push plate 42 upwardly. When the divider is moved forward- 1y, to the right as shown in FIG. 2, to move the clips beneath base 15, plate 42 will drop through perforation 14 into the locking position. In the embodiment shown, only one locking device 41 is provided but several locking devices can be used, if desired. Also, the locking device need not be adjacent one of the clips so long as it is positioned to pass through one of the perforations when the clips are engaged under base 15.
With the divider in place, flanges 34 do not rest directly on the base of the shelf as is clear from FIG. 4. Clips 35 include a flat portion 37 from which hook end 36 extends and through which the clips are secured to the flanges, as by means of welding. Flat portions 37 overlie base 15 of the shelf. The flat portion 37 through which plate 42 extends in the disclosed embodiment is provided with an opening 38 sufficiently large to receive, plate 42 and lip 44 so that they plate and lip may be withdrawn completely during insertion and removal of the divider.
The dividers disclosed herein are shown extending transverse to the length of the shelf. It will be understood that the dividers could also extend parallel to the longitudinal axis of the shelf and any number of dividers can be provided in order to divide the shelf as desired to receive merchandise.
It will thus be seen that the objects set forth above, among those made apparent from the preceding description, are efliciently attained and, since certain changes may be made in the above construction without departing from the spirit and scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
