Abstract
Abstract The present invention relates to a device for retrieving waste deposits and, more particularly, animal excrement and the like. The device includes an outer tubular shaft having a handle portion formed in the shape of the handle of a walking cane. An inner shaft is concentrically disposed within said outer shaft and is moveable longitudinally with respect thereto. Such longitudinal movement of the inner shaft causes a tension spring to bear against a normally-open hinge which, in the absence of circumferential force thereabout, will exhibit its normally-open position. Longitudinal movement of the inner shaft away from the handle will cause said tension spring to bear against the hinge thus permitting said hinge to open selectably as may be desired. After opening, a throwaway box is attached to the fingers of the hinge and, through an upper movement of the inner shaft, the retrieval of an animal deposit is achieved. Through further selectable movement of the inner shaft, the throwaway box is pulled away and ultimately detached from the device in order to permit it to be easily dropped into a waste disposal area.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
313 words
An apparatus for retrieving waste material comprising: a. an outer tubular shaft having at one end thereof a U-shaped handle end and at the opposite end thereof a distal end; b. an inner tubular shaft telescopically associated within said outer shaft at said distal end thereof; c. a hinged grasping member comprising a unitary base secured at one end thereof within the distal end of said inner shaft and at the other end thereof defining finger elements extending in their natural state in opposite directions to each other, said grasping member prepared from a resilient, flexible material, said finger elements adapted to flex toward each other to grasp and secure an open disposable litter receptacle during the placement of litter therein and to subsequently effect the closing of said receptacle; d. a trigger element rotatably secured to said handle end; e. a connecting wire attached to said trigger and passing axially through the length of said outer shaft and said inner shaft, respectively, said connecting wire passing through an opening provided in said base and terminating between said fingers, said wire having its degree of tension controlled by the movement of said trigger element; f. a ball element attached to said wire at its point of termination and emergence from said base, said ball element serving to pass through a corresponding opening in said litter receptacle to secure said receptacle in position between said fingers during the placement of said litter therewithin; and g. a biasing element disposed about said wire and abuttingly disposed to said base, said biasing element serving to accomplish a fine control of the closing of said fingers by said trigger, whereby longitudinal movement of said outer shaft toward said handle end will cause the release of said fingers into a naturally open opposed disposition for cooperation with said ball element to associate with an open, unused waste receptacle.
Claim 2
Independent Claim
313 words
An apparatus for retrieving waste material comprising: a. an outer tubular shaft having at one end thereof a U-shaped handle end and at the opposite end thereof a distal end; b. an inner tubular shaft telescopically associated within said outer shaft at said distal end thereof; c. a hinged grasping member comprising a unitary base secured at one end thereof within the distal end of said inner shaft and at the other end thereof defining finger elements extending in their natural state in opposite directions to each other, said grasping member prepared from a resilient, flexible material, said finger elements adapted to flex toward each other to grasp and secure an open disposable litter receptacle during the placement of litter therein and to subsequently effect the closing of said receptacle; d. a trigger element rotatably secured to said handle end; e. a connecting wire attached to said trigger and passing axially through the length of said outer shaft and said inner shaft, respectively, said connecting wire passing through an opening provided in said base and terminating between said fingers, said wire having its degree of tension controlled by the movement of said trigger element; f. a ball element attached to said wire at its point of termination and emergence from said base, said ball element serving to pass through a corresponding opening in said litter receptacle to secure said receptacle in position between said fingers during the placement of said litter therewithin; and g. a biasing element disposed about said wire and abuttingly disposed to said base, said biasing element serving to accomplish a fine control of the closing of said fingers by said trigger, whereby longitudinal movement of said outer shaft toward said handle end will cause the release of said fingers into a naturally open opposed disposition for cooperation with said ball element to associate with an open, unused waste receptacle.
Claim 3
Dependent Claim
24 words
The apparatus as recited in claim 1 in which said handle end is formed in the shape of the handle of a walking cane.
Claim 4
Dependent Claim
57 words
The apparatus as recited in claim 2 in which said outer tubular shaft includes means for insertion into any one of a plurality of transverse positions with respect to said inner tubular shaft in order to thusly obtain a total length of the present apparatus suitable, in use as a walking cane, to users of varying heights.
Claim 5
Dependent Claim
23 words
The apparatus as recited in claim 1 in combination with a foldable throwaway box adapted for insertion within the fingers of said hinges.
Claim 6
Dependent Claim
35 words
The apparatus as recited in claim 1 in which said hinge is molded in a normally open position so as to create a "natural memory" of the fingers thereof into such a normally open position.
