Abstract

A device for removing litter from rugs, carpets, or floors comprises a housing having an elongated handle connected thereto and a tape cartridge disposed therein, the housing further comprising means for selectively advancing the tape in the cartridge to present a tacky surface for contacting and thus removing the litter.

Claims

1. An adhesive tape device for removing litter from carpets, rugs and the like, which comprises:

a housing adapted to receive to a tape cartridge means;

tape cartridge means adapted to be removably fitted into said housing, said cartridge means comprising a first reel for supplying a length of tape and a second reel for taking up said length of tape, said cartridge being movable within said housing from a first extended position to a second retracted position;

biasing means mounted in said housing for normally disposing said cartridge in said first extended position; and

tape advancing means mounted on said housing for rotating said second reel to thereby advance a length of tape from said first reel in response to a sequential movement of said cartridge from said first extended position to said second retracted position and back to said extended position, said length of tape having an outwardly facing tacky surface, a portion of said tacky surface being positioned outside of said housing and being adapted to contact the litter to be removed when said cartridge is in said retracted position, said extended position and all intermediate positions therebetween.

2. The device of claim 1, further comprising handle means mounted on said housing.

3. The device of claim 2, wherein said housing further comprises spring clip means, wherein said cartridge means comprises tab members, and wherein said tab members are releasably gripped by said spring clip means to removablely secure said cartridge within said housing.

4. The device of claim 2, wherein said biasing means comprises spring means mounted within said housing so as to contact and force said cartridge means to said first extended position.

5. The device of claim 3, wherein said biasing means comprises spring means mounted within said housing so as to contact and force said cartridge means to said first extended position.

6. The device of claim 3, wherein said cartridge means further comprises first cogged wheel means fixedly mounted to said second reel for rotation therewith, and wherein said tape advancing means comprised rack means, second and third cogged wheel means and lever means, said rack means being mounted to said housing for movement relative to said second and third cogged wheel means so as to impart rotational movement in a first direction to said second cogged wheel means in response to movement of said cartridge means toward said retracted position and to impart rotational movement to said second cogged wheel means in a second opposite direction in response to movement of said cartridge means to said extended position, said lever means being mounted on said second cogged wheel means for movement therewith, said lever means being operatively connected to said third cogged wheel means and being adapted to move said third cogged wheel means only when said second cogged wheel means rotates in said second direction, said third cogged wheel means being operatively connected to said first cogged wheel means so as to impart rotational movement to said first cogged wheel means only in said first direction such that when said cartridge means is moved from said extended position to said retracted position and back to said extended position said first cogged wheel means is rotated in said first direction to thereby rotate said second reel in said first direction and thereby advance said tape from said first reel.

7. The device of claim 4, wherein said cartridge means further comprises first cogged wheel means fixedly mounted to said second reel for rotation therewith, and wherein said tape advancing means comprised rack means, second and third cogged wheel means and lever means, said rack means being mounted on said housing for movement relative to said second and third cogged wheel means so as to impart rotational movement in a first direction to said second cogged wheel means in response to movement of said cartridge means toward said retracted position and to impart rotational movement to said second cogged wheel means in a second opposite direction in response to movement of said cartridge means to said extended position, said lever means being mounted on said second cogged wheel means for movement therewith, said lever means being operatively connected to said third cogged wheel means and being adapted to move said third cogged wheel means only when said second cogged wheel means rotates in said second direction, said third cogged wheel means being operatively connected to said first cogged wheel means so as to impart rotational movement to said first cogged wheel means only in said first direction such that when said cartridge means is moved from said extended position to said retracted position and back to said extended position said first cogged wheel means is rotated in said first direction to thereby rotate said second reel in said first direction and thereby advance said tape from said first reel.

8. The device of claim 5, wherein said cartridge means further comprises first cogged wheel means fixedly mounted on said second reel for rotation therewith, and wherein said tape advancing means comprised rack means, second and third cogged wheel means and lever means, said rack means being mounted on said housing for movement relative to said second and third cogged wheel means so as to impart rotational movement in a first direction to said second cogged wheel means in response to movement of said cartridge means toward said retracted position and to impart rotational movement to said second cogged wheel means in a second opposite direction in response to movement of said cartridge means to said extended position, said lever means being mounted on said second cogged wheel means for movement therewith, said lever means being operatively connected to said third cogged wheel means and being adapted to move said third cogged wheel means only when said second cogged wheel means rotates in said second direction, said third cogged wheel means being operatively connected to said first cogged wheel means so as to impart rotational movement to said first cogged wheel means only in said first direction such that when said cartridge means is moved from said extended position to said retracted position and back to said extended position said first cogged wheel means is rotated in said first direction to thereby rotate said second reel in said first direction and thereby advance said tape from said first reel.

9. The device of claim 6, wherein said cartridge means further comprises means to restrict free reeling of said first reel means.

10. The device of claim 9, wherein said free reeling restricting means comprises forth cogged wheel means fixedly mounted to said first reel for rotation therewith and second lever means mounted on said cartridge means and operatively connected to said forth cogged wheel means to restrict but not preclude rotation of said fourth cogged wheel means.

11. The device of claim 7, wherein said cartridge means further comprises means to restrict free reeling of said reel means.

12. The device of claim 8, wherein said cartridge means further comprises means to restrict free reeling of said reel means.
