Abstract
ABSTRACT
A refuse collecting tool for the sanitary collection of animal excrement or other refuse which is preferably not handled directly. The device includes a tubular handle having a gripping portion attached to its upper end and a scoop, elliptical in cross-section, attached to its lower end. The scoop is divided into opposing jaws which are hinged together along their top edges and constantly urged to a closed condition by coil springs attached to their end walls. A rod extending through the tubular handle is provided on its top end with a lever which extends radially through slots in the tubular handle that are located beneath the gripping portion, and on its other end with a flat rectangular plate sized to fit within the center region of the closed scoop. Upward pressure on the lever forces the opposing jaws of the scoop open as the rectangular plate is forced upwardly into the decreasing diameter of the top of the scoop.
The rectangular plate also prevents collected refuse from entering and fouling the moving parts of the tool. The advantage of the tool is its simple construction which renders it light weight, reliable in use, economical to manufacture and practically maintenance free.

~3(~6~5 FIG. 4 is a transverse cross-section of the device shown in FIG. 1 with the scoop in an open condition.
A refuse collecting device for the sanitary collection of animal excrement or other refuse which is preferably not handled directlyl is generally indicated by the reference 10, as shown in FIG. 1. A preferred embodiment of the device includes a hollow handle member 12 which is provided with a cap or gripable region 14 on its top end and a lever 16 for opening the scoop, generally indicated by reference 18. The scoop 18 is substantially elliptical in cross-section and divided along a plane coincident with the ma~or ~xis of its elliptical cross-section into two opposing ~aws 20a and 20b. The ~aws are hinged together along their opposing top edges by a pair of hinges 22. Jaws 20a and 20b are constantly urged to a closed condition by a pair of springs 24 connected respectively across each end wall of the scoop 18. The springs 24 may be secured to the ~aws 20a and 20b with bolts 25 (as illustrated) or by lugs or eyelets molded as an integral part of the end walls of each jaw.
FIG. 2 shows the refuse collecting device 10 in longitudinal cross-section. As is apparent, the hollow tubular handle 12 houses a shaft 24 which is connected to lever 16 by a pin 26. The shaft 24 may be a plastic or wooden dowel sized to be slidable within the tubular handle 12. The lever 16 may, of course, be affixed to shaft 24 by a number of alternate fastening methods including glue, screws, or similar fasteners.
Shaft 24 is connected on its lower end by a screw 28, or some equivalent fastener, to a rectangular plate 30. The function of the rectangular plate 30 is described below in reference to FIGS. 3 and 4.
As shown in FIG. 3, handle 12 is provided with a vertical slot 32 which permits lever 16 to be raised toward the grip 14 by a gripping ; pressure applied by a user's hand. Upward pressure on the lever 16 raises shaft 24 within tubular handle 12 and likewise raises rectangular plate 30 within the scoop 18. As rectangular plate 30 is forced into the increasingly restricted space defined by the inner walls of the scoop 18, the opposing jaws 20a and 20b of the scoop are forced outwardly against the tension of coil springs 24. When the lifting pressure on lever 16 is ; released, the tension of coil springs 24 forces rectangular ~ rX PAT 1041~1 ~3~ S
plate 30 downwards and closes opposing ~aws 20a and 20b.
In a preferred embodiment of the invention, tubular handle 12 is formed from a length of rigid plastic tubing, preferably PVC or ABS
tubing. Glued to the lower end of tubular handle 12 is a pipe coupling 34 of the type provided with an external thread on its free end. Sandwiched between coupling 34 and scoop 18 is a compressible rubber washer 36. The tubular handle 12 is secured to the scoop 18 by a cup nut 38 (see FIG.
2). Sandwiched between cup nut 38 and the top walls of scoop 18 is a flexible sheet 40, preferably a plastic sheet, which extends longitudinally and laterally of cup nut 38 to provide stability between the scoop 18 and the tubular handle 12. Many alternative connections between the tubular handle and the scoop 18 are, of course, possible and obvious to those skilled in the art. Hinges 22 may be any convenient leaf hinge member srewed or glued to opposing jaws 20a and 20b. Alternatively, the hinge may be a plastic molded hinge, well known in the art, which is manufactured as a unitary part of ~aws 20a and 20b.
The material of preference for the construction of the scoop 18 is a molded polyvinyl chloride, polyethylene, nylon or a similar rigid plastic, however, cast or sheet formed metals may be used wlth success. The tubular handle 12 may likewise be formed from a metallic tube rather than a plastic pipe. As stated above, the shaft 24 is conveniently a wooden or plastic dowel cut to the proper length, however, aluminum or copper tubing i~ also satisfactory. The rectangular plate 30 is preferably a rigid plastic such as nylon ~ince these materials tend to be self-lubricating ; and therefore minimize the wear on the inner walls of jaws 20a and 20b.
In use, the scoop is carried in one hand with grip 14 in the palm of the hand and the fingers clasped about lever 16. When animal excrement or some other article of refuse is to be collected, lever 16 is raised by squeezing pressure of the fingers. The plate 30 i9 thereby moved upwardly to force open ~aws 20a and 20b (see FIG. 4). The open ~aws are placed over the article to be collected and the lever 16 is released. Coil springs 24 force jaws 20a and 20b to a closed condition, scooplng up the refuse so that it can be carried to a di~posal container or site where , , .~ .:
pressure on lever 16 opens the ~aws and releases the refuse from the scoop. It should be noted that rectangular plate 30 is preferably sized to fit relatively closely within the walls of scoop 18 when the scoop is in its closed condition. The plate 30 therefore serves a dual purpose.
It acts as an opening mechanism for the cylindrical scoop and as a rigid diaphragm for preventing the entry of waste into the moving parts of the device.
Changes and modifications in the specifically described embodiments can be carried out without departing from the scope of the invention which is intended to be limited only by the scope of the appended claims.
