Abstract
A rotary brush or other rotary implement constructed in accordance with the instant invention includes a first fixed handle means and a second movable handle means hinged to the fixed handle and operable by squeezing. The brush head to be rotated is mounted on an elongated rod which extends through the handle portion. The movable handle carries a rack which engages a pinion gear carried on the rod for rotating the brush. The pinion gear includes internally disposed alternately selectable ratchet portions which upon selection by the user cause the brush head to rotate in a first and only a first direction upon a squeezing of the handle. Upon user adjustment, the brush will rotate in the second and only the second direction upon the squeezing of the handle. The rotation mechanism of the brush is completely enclosed within the handle portion.
Claims6
A rotary implement comprising:
- first handle means;
- a rod having first and second ends, said rod being rotatably and slidably mounted to said handle means, said rod being slidably displaceable between first and second positions;
- an implement head mounted to said first end of said rod means;
- a second movable handle means pivotally mounted to said first handle means;
- rack means disposed on said second handle means;
- a pinion gear rotatably mounted about said second end of said rod means for rotation by said rack means;
- at least a portion of said pinion gear having external toothing for engagement with said rack means for rotation therewith;
- said pinion gear including first and second oppositely disposed ratchet means, said first ratchet means locking said gear to said rod when said gear is rotated in a first direction, said first ratchet means disengaging said gear from said rod when said gear is rotated in a second direction, said second ratchet means locking said gear to said rod when said gear is rotated in a second direction, said second ratchet means disengaging said gear from said rod when said gear is rotated in said first direction;
- means disposed internally within said gear for the alternate engagement of one of said first and said second ratchet means, said means including splines disposed on said rod and teeth disposed on said first and second ratchet means, said splines engaging said first ratchet means when said rod is in said first position, said splines engaging said second ratchet means when said rod means is in said second position to thereby permit the rotation of said head upon the operation of said moveable handle dependent upon whether said first or said second ratchet means is engaged.
