Claims:
What is claimed is
1. A cage-like structure adapted to be removably secured to the peripheral edge of a rectangular pallet, said structure including: a pair of side panels spaced and parallel to one another; a pair of end panels spaced and parallel to one another; and a plurality of locking brackets secured to respective ones of said panels at the adjacent edges thereof, each of said locking brackets including an inclined clamp slide member secured to one of the panels, and a gravity clamp mounted in sliding engagement with said clamp slide member and having a hooked end portion engaging the edge of the adjacent panel.
2. The combination defined in claim 1, and which includes a plurality of foot brackets secured to said panels at the lower corners thereof; each of said foot brackets having a flanged section and each of said foot brackets being mounted in an angular sliding relationship with the one of the adjacent panels, so that downward movement of such panel draws said flanged section into gripping relationship with the adjacent edge of the pallet.
3. The combination defined in claim 1, in which one of said panels includes an upper section and a lower section hinged to one another, and a pair of said locking brackets being secured to said upper section to hold it in a closed and locked position.
4. The combination defined in claim 2, in which each of said foot brackets includes locking means for securing the lower edge of the other of the adjacent panels thereto.
Description:
BACKGROUND OF THE INVENTION
Pallets are presently in widespread use in warehouses, and in other places, for supporting loads of goods for transportation from one location to another, either within the warehouse or to distant points. One reason for the widespread use of the pallet is that it supports its load up from the floor of the warehouse, so that the forks of a fork lift truck, or the like, may be easily slipped under its load supporting surface in order that the pallet and its load may be conveniently lifted up for movement from one point to another.
In order to widen the field of use of such pallets, it is usual in the prior art to provide walls which may be removably mounted on the pallet to form a bin or container for the goods carried thereby. The present invention is concerned with such a structure, and it provides a cage-like assembly which is composed of individual wall panels removably locked to one another, and which may easily and conveniently be clamped to the peripheral edge of the pallet to provide a rigid and stable container, and yet which may be easily removed from the pallet and which may be easily disassembled.
A feature of the structure of the invention is the provision of a hinged section on one of the walls to permit access to the container. In accordance with the invention, the hinged section is held in a closed position by unique movable gravity locking clamps which are conveniently moved down into locking positions, as will be described.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT
The cage-like structure of the present invention, as shown in FIG. 1 includes a pair of side panels 10 and 12 which are supported in spaced parallel relationship when the structure is assembled and in place on a pallet, such as the illustrated pallet 14. The side panels 10 and 12 may be similar in their construction, and each may include a top tubular member 18 and a bottom tubular member 19, welded to a pair of side tubular members 21 to form a closed rectangular shape, as shown. A plurality of wires 20 extend upwardly across the area enclosed by the tubular members, and are welded to the tubular members 18 and 19. A plurality of further wires 22 extend across and are spot welded to the wires 20, and the wires 22 are welded to the side tubular members 21 to constitute shelf supports.
The structure also includes an end panel 24 and an end panel 26. The end panel 26, for example, may include a lower section 26a and an upper section 26b hinged to one another, so that the upper section 26b may be turned down to provide an access gate to the interior of the structure. The end panels may have generally the same structure of the side panels, and each may include upper and lower tubular members 18 and 19, side tubular members 21, and wires 20.
The side panels described above are intercoupled to one another by means of a plurality of gravity clamp assemblies 30. The clamp assemblies 30 may each have the form shown in FIGS. 3 and 4. Each clamp assembly, as shown in FIG. 4 includes a diagonal clamp slide 50 which is welded to the adjacent upper tubular member 18 and horizontal wire 22. A gravity clamp 52 is supported on the slide 50 by means of a guide 54. The guide 54 is welded to the rear slide of the clamp 52, as best shown in FIG. 4. The clamp 52, has a hook-shaped configuration, as also shown in FIG. 4.
By means of the clamp assemblies 30, the side panels and end panels of the assembly are held rigidly together and the access gate is held closed, when the structure is in the assembled condition of FIG. 1. Yet, the access gate may be easily opened, and the panels may be easily disassociated from one another, merely be moving the gravity clamps upwardly to release them from their hooking engagement of FIG. 3, as shown by the shadow representation in FIG. 3 of the clamp 52.
A foot bracket assembly 40 is provided at each of the lower corners of the structure. The foot bracket assembly is shown in more detail in FIG. 2, and, as illustrated, it includes a plate-like section 40a having a diagonal slot therein, and it also includes a second section 40b, with an integral flange 40c. A short rectangular tubular member 44 is welded, or otherwise attached to the tubular members 19 and 21. A carriage bolt 46 extends through the member, and its head is received in the slot in section 40a. The relationship is such that as the side panels 10 and 12 are moved down towards the plane of the pallet, the bolt 46 rides down the diagonal slot so that the flange 40c is drawn inwardly into a firm clamping relationship with the pallet, and the structure is firmly and rigidly held on the pallet.
A socket 45 is provided on the top of section 40b which is engaged by a hook in the underside of the corresponding lower tubular member 19, so that the end panels 24 and 26 may be hooked in place on the foot brackets.
The invention provides, therefore, an improved, simple and inexpensive cage for use in conjunction with a pallet, to provide a container for goods carried by the pallet. The elements of the cage-like structure are intercoupled to one another by similar locking brackets, as described, and further similar locking brackets are used to clamp the structure to the edge of the pallet. An access door is provided, which is held in closed condition by a gravity clamp type of latch, and further similar locking assemblies.
It will be appreciated that although a particular embodiment of the invention has been shown and described, modification may be made. It is intended to cover such modifications in the following claims.
