BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to pick-up tools and devices for collecting refuse and waste. More specifically, the present invention relates to a pick-up tool that can be used to grasp refuse, dirt, or waste, and sift the same. An exemplary use of the present invention is picking up manure while sifting out and preserving stall bedding material or other elements that may be inadvertently picked up in the process.
The present invention is a general purpose pick-up tool with a sifting function. In one contemplated use, the device can be used to pick up animal droppings and manure. In farm or horse stable environments, cleaning out a stall can be time consuming work. Tools typically include shovels, muck rakes, and other tools to clean out manure therefrom. While these tools are useful, they can be ineffective in gathering all manure for removal, particular smaller pieces that are difficult to pick up individually. Small pieces can drop to the ground and become littered across the stall, requiring hand clean up or residual waste left in the stall. Therefore, a pick-up tool is useful for gathering smaller clumps and removing the same.
However, while gathering smaller quantities with a pick-up tools is desired, so too is retaining the stall bedding during the cleaning process. Therefore, a need exists for a pick-up device that can remove manure and other items while sifting and preserving reusable stall bedding and other elements, such as pine shavings and the like. The present invention provides a sifting pick-up tool. The tool is adapted to scoop waste or other material while sifting granular material therefrom. The tool comprises an elongated frame with a pair of jaw members along one end. The jaw members can be moved relative to one another using a slidable handle along the frame, while the jaw members are biased to remain in an open or closed state. While picking up waste and other material, loose and granular material is sifted through a mesh sifting screen disposed along one or both of the jaw members. Overall, the tool provides an effective means for cleaning animal stalls and sifting waste removed therefrom.

DETAILED DESCRIPTION OF THE INVENTION
Reference is made herein to the attached drawings. Like reference numerals are used throughout the drawings to depict like or similar elements of the sifting pick-up device of the present invention. For the purposes of presenting a brief and clear description of the present invention, the preferred embodiment will be discussed as used for picking up items and sifting granular, loose, or liquid material therefrom. The figures are intended for representative purposes only and should not be considered to be limiting in any respect.
Referring now to FIGS. 1-3, there are shown view of the sifting pick-up device of the present invention. The device is one that a user manipulates in order to grasp and pick-up various items, typically from a yard or other ground surface. Once grasped, the device can sift the material, dropping loose material and retaining larger portions thereof. One particular use of the device is to pick-up manure and sift out loose grass and hay therefrom. Other uses are contemplated. The device is handheld and manipulated by a user to secure items between its jaw members 51, 61.
The sifting pick-up device comprises an elongated frame 20 having a length, a proximal end 22, and a distal end 21. A user grasps the elongated frame 20 and directs the distal end 21 towards items to be secured. Along the distal end 21 is a first jaw member 61 and a second jaw member 51, whereby the jaw members are movable relative to one another in order secure items therebetween. A slidable handle 11 is disposed along the length of the elongated frame 20, whereby the slidable handle 11 is slidable along the length thereof. In turn, the slidable handle 11 is coupled to at least one of the first jaw member 61 or second jaw member 51, such that movement of the slidable handle 11 in a first direction 101 along the elongated frame 20 moves 100 one or both of the first jaw member 61 and second jaw member 51.
In one embodiment, the handle 11 is connected to one or both of the jaw members 51, 61 via one or more cables 81. The cables 81 are preferably substantially inelastic members comprising a resilient material, such as braided steel cord or the like. The cables 81 extend between the handle 11 and the distal end 21 of the elongated frame 20 such that movement of the handle 11 is coupled to the jaw members 51, 61. Sliding motion of the handle 11 is thus translated into a change in relative position of the first and second jaw members 51, 61. In this embodiment, it is further preferred that the handle 11 be spring biased in order to return the handle 11 to a starting position after it has been moved along the frame 20. Thus, the jaw members 51, 61 are biased to be in a starting position, and movement from this biased position changes the starting position of the jaws. The starting position for the jaws is preferably in an open position as shown in FIGS. 1 and 2.
Referring to FIGS. 1-4, the handle 11 within the frame 20 preferably connects to a rectangular base that slides within a channel 25 in the frame 20. The rectangular base comprises at least two side members 12 and one cross member 13. The side members 12 secure within channels 24 in the open interior 25 of the frame 20 and the cross member 13 extends laterally thereacross. The open interior 25 of the frame 20 is preferably an opening that extends along the length of the frame 20 and accommodates the handle 11, its rectangular base, the cables 81, and a return spring 18 that biases the handle 11. In use, the user handles the device by holding a grip 29 disposed along the proximal end 22 of the frame 20, while simultaneously gripping the handle 11 along the frame length. The user can move the handle 11 relative to the proximal end 22 in order to change the position of the jaw members 51, 61 when attempting to ensnare or grasp an item therebetween.
The pick-up device of the present invention preferably has a first jaw member 61 and a second jaw member 51, whereby the jaw members move relative to one another in order to grasp items as the user coordinates the positioning of the jaw members. In one embodiment, the jaw members 51, 61 each have an upstanding perimeter 56, a rear surface 59, an outer surface, and a jaw surface thereacross. The upstanding perimeters of each jaw either overlap one another or abut against one another when the slidable handle 11 is moved and when the jaws are moved together. Moreover, the jaw surface of at least one of the jaw members 51, 61 further comprises an open, sifting screen surface 55. In one embodiment, the second jaw member 51 has a sifting screen surface 55, while the first jaw member 61 has a solid jaw surface 65.
The jaw surfaces 55, 65 are webs extending across each jaw, and the jaw surfaces 55, 65 may both be sifting screens or only one of the jaw members may be sifting screens. In the latter case, the sifting screen is preferably disposed along the jaw that forms the lower of the two jaw members. That is, the jaw that will accommodate sifting of material 201 from the interior of the jaws using gravity as larger particles 200 are retained on the sifting screen surface 55. In one embodiment of the device, the handle 11 is an upstanding member disposed substantially perpendicular to the frame 20. In this embodiment, the first jaw member 51 is disposed along an opposite side of the frame relative to the handle such that a user grasping the handle 11 and the proximal end of the frame can sift material through the sifting screen 55 of the first jaw member 51, which forms the lower jaw member of the two in this orientation.
The jaw members 51, 61 comprise upstanding perimeters 56, 66, wherein the upstanding perimeters have upper edges 67. The edges either abut one another or overlap when the jaws are in a closed state. In addition the outer edges 58, 68 of the jaw members 61, 51 may further comprise serrated edges in order to improve grasping items with the device. In the closed state, the handle 11 is moved from its starting position and to an extended position. In the extended position, the return spring is elongated and is biasing the handle 11 to return to its starting position. Movement of the slidable handle 11 from the staring position tensions the cables 81 along the frame 20 and draws the jaw members together. Moreover, in the closed state, the first jaw member 61 and the second jaw member 51 form an enclosed interior volume.
Referring to FIG. 5, there is shown one embodiment of the distal end of the device and the jaw members 51, 61 in an open state. As shown, in this embodiment the cables 81 extend through the rear surface 59 of the second jaw member 61 and connect to the first jaw member 51. When the handle is moved away from the distal end of the frame, the cables 81 are tensioned. The cables 81 then draw the first jaw member 61 towards the second jaw member 51 as the cables 81 are drawn through the frame 20 by the slidable handle. This allows items to be grasped between the jaw members 51, 61, while one or more jaw sifting screen surfaces 55 allow the grasped items to be sifted. This embodiment is but one configuration of the present invention and is not meant to be limiting. The second jaw member 51 may alternatively be drawn towards the first jaw member 61, or the jaw members may both be movable towards one another by way of the cables.
In particular, the first jaw member 61 may be pivotably attached to the distal end of the elongated frame 20 and the second jaw member 51 may be fixed relative to the frame. Alternatively, the second jaw member 51 may be pivotably attached to the distal end of the elongated frame 20 and the first jaw member 61 may be fixed relative to the frame. Finally, the two jaw members 51, 61 may both be pivotably relative to the frame 20 and both move together when the handle is moved.
In addition, as shown in FIG. 4, the handle 11 may be an upstanding member extending substantially perpendicular to the length of the elongated frame 20. This allows a user to grasp the upstanding handle 11 with one hand while gripping the end grip 29 of the frame 20 along the proximal end 22 thereof. Alternatively, however, the handle 11 may be positioned within the same plane as the elongated frame 20 and move within its open interior 25 (not shown). The handle 11 may be disposed laterally across the open interior of the frame and be substantially parallel to the cross member 13 of its rectangular base. In this embodiment, the handle 11 may also be positioned within the open interior of the end grip 29 along the proximal end 22 of the frame. Thus, a user can grasp the handle 11 within the end grip 29 and draw the handle 11 against the grip, in-plane with the frame 20 and within its open interior.
Overall, the present invention provides an improvement in manure rakes and pick-up tools. The device is beneficial to individual homeowners, and even farmers, equestrians, zookeepers, or any other individuals who boards animals. The manure scooper introduces a more efficient and sanitary way to pick-up animal waste from stalls while sifting the contents thereof. In addition, the present invention provides a general purpose pick-up tool that is unrelated to manure and animal boarding, which may be used for picking-up items from a yard by a homeowner. No claim is made to limit the use of the present invention.
