Abstract
Abstract A portable article retrieving apparatus is enclosed within a housing having a base member mounted therein with a frame upstanding from the base member and a storage bobbin sleeved on a shaft which is rotatably mounted on the frame and rotated in response to activation of power means. A flexible member has an article to be retrieved affixed to one end thereof and the other end affixed to the bobbin. Bobbin positioning means are operatively connected to the bobbin to position same to receive an intermediate portion of the flexible member in response to rotation of the shaft for winding the flexible member around the bobbin and means operated from outside the housing for allowing substantially drag-free unwinding of the flexible member therefrom.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
338 words
An article retrieving apparatus comprising: a. a base member having a frame upstanding therefrom; b. an elongated rotatable shaft spaced from said base member and supported on said frame, said shaft having spaced opposite ends; c. a storage bobbin sleeved on said rotatable shaft and movable longitudinally therealong, said storage bobbin having a pair of spaced substantially parallel flanges and a plurality of cam surfaces on an exterior surface of one of said flanges; d. means operatively engaging said shaft for effecting rotation of said shaft; e. an elongate flexible member having an article to be retrieved affixed to one end thereof; f. means operatively engaging said bobbin and said shaft for reciprocating said bobbin to thereby receive an intermediate portion of said flexible member in response to rotation of said shaft; g. means mounted on said shaft for longitudinal movement relative to said shaft and rotatable with said shaft and for guiding the intermediate portion of said flexible member into engagement with said bobbin for winding said intermediate portion of said flexible member around said bobbin in response to rotation of said shaft, said means for guiding the intermediate portion of said flexible member into engagement with said bobbin includes a cap having a flange enclosing a portion of said bobbin during reciprocation thereof and movable between a position engaging one end of said shaft and a position spaced from the one end of said shaft and a pin resiliently mounted on said cap and movable between an extended position having a free end of said pin extending exteriorly of said shaft and a retracted position having the free end of said pin within said cap and the other end between said cap and said shaft; and h. a portion of said pin engageable by one of said cam surfaces on said bobbin when said pin is in said retracted position whereby rotation of said shaft effects movement of said pin to said extended position to guide the intermediate portion of said flexible member into said bobbin.
Claim 2
Dependent Claim
338 words
An article retrieving apparatus comprising: a. a base member having a frame upstanding therefrom; b. an elongated rotatable shaft spaced from said base member and supported on said frame, said shaft having spaced opposite ends; c. a storage bobbin sleeved on said rotatable shaft and movable longitudinally therealong, said storage bobbin having a pair of spaced substantially parallel flanges and a plurality of cam surfaces on an exterior surface of one of said flanges; d. means operatively engaging said shaft for effecting rotation of said shaft; e. an elongate flexible member having an article to be retrieved affixed to one end thereof; f. means operatively engaging said bobbin and said shaft for reciprocating said bobbin to thereby receive an intermediate portion of said flexible member in response to rotation of said shaft; g. means mounted on said shaft for longitudinal movement relative to said shaft and rotatable with said shaft and for guiding the intermediate portion of said flexible member into engagement with said bobbin for winding said intermediate portion of said flexible member around said bobbin in response to rotation of said shaft, said means for guiding the intermediate portion of said flexible member into engagement with said bobbin includes a cap having a flange enclosing a portion of said bobbin during reciprocation thereof and movable between a position engaging one end of said shaft and a position spaced from the one end of said shaft and a pin resiliently mounted on said cap and movable between an extended position having a free end of said pin extending exteriorly of said shaft and a retracted position having the free end of said pin within said cap and the other end between said cap and said shaft; and h. a portion of said pin engageable by one of said cam surfaces on said bobbin when said pin is in said retracted position whereby rotation of said shaft effects movement of said pin to said extended position to guide the intermediate portion of said flexible member into said bobbin.
Claim 3
Dependent Claim
154 words
An article retrieving apparatus as set forth in claim 1 wherein said means for guiding the intermediate portion of said flexiBle member into engagement with said bobbin includes: a. a bore extending longitudinally through said shaft and coaxial with said shaft; b. a second shaft movably received within said bore through said first named shaft, said cap being mounted on said second shaft and movable therewith, said other end of said pin being in engagement with said second shaft when said pin is in the retracted position; c. resilient means engaging said first named shaft and said second shaft for urging said cap into engagement with the one end of said first named shaft; and d. a flat surface on said first named shaft and on said second shaft, said flat surfaces being in engagement whereby said second shaft and said cap and pin on said cap are rotated with said first named shaft.
Claim 4
Dependent Claim
94 words
An article retrieving apparatus as set forth in claim 2 including: a. a housing supported on said frame and having a portion surrounding said first named shaft, said portion of said housing being spaced from said cap to permit the intermediate portion of said flexible member to move therebetween; b. a guide aperture in said housing and spaced from said bobbin; and c. a guide arm mounted on said bobbin and extending outwardly therefrom and received in said guide aperture in said housing thereby holding said bobbin against rotation with said first named shaft.
