Abstract

A reversible, portable winch for attachment to a utility rack. It includes a shaft for rotation; a take-up reel for winding and unwinding a flexible securing strap, the take-up reel being connected to the shaft and affixed thereto for rotation therewith; a flexible securing strap attached to the take-up reel at a first end thereof; a plurality of bidirectional pawl-engaging teeth located about the shaft and so as to prevent and permit rotation of the take-up reel and the shaft by being engaged and disengaged with a pawl; a winding mechanism connected to the shaft or the take-up reel for winding the shaft and the take-up reel; support for supporting the shaft and the pawl. The winch is connected via its shaft to a support and the pawl may be movably connected to the support as well. In preferred embodiments, the support is a component of a utility rack such as a ladder utility rack attached to the cargo bed of a pick-up truck or the top of a motor vehicle.

Dependent claims

A combination reversible, portable winch and a utility rack, which comprises:

(A) a utility rack for a vehicle which includes at least one commonly connected horizontal cross member and at least two mounting brackets, at least one of said cross member and said brackets having a shaft orifice adapted to receive a shaft of a winch;
(B) a reversible, portable winch adapted for attachment to said utility rack, which includes:
(a) a winch shaft for rotation which is inserted into said orifice of said utility rack;
(b) a take-up reel for winding and unwinding a flexible securing strap, said take-up reel being connected to said shaft and affixed thereto for rotation therewith;
(c) a flexible securing strap attached to said take-up reel at a first end thereof;
(d) a plurality of bidirectional pawl-engaging teeth located about said shaft and affixed thereto so as to prevent and permit rotation of said take-up reel and said shaft by being engaged and disengaged with said pawl;
(e) a pawl operationally connected to said teeth for engaging and disengaging thereof;
(f) winding means connected to one of said shaft and said take-up reel for winding said shaft and said take-up reel and,
wherein said shaft orifice is a securing means for temporarily securing said shaft to said utility rack so as to permit rotation of said shaft in said shaft orifice, removal of said shaft from said shaft orifice and reinsertment thereof on an opposite side of said shaft orifice, so as to permit, in a first location, clockwise winding and counterclockwise unwinding, and in a second location being a reversed position, counterclockwise winding and clockwise unwinding.

A combination reversible, portable winch and a utility rack, which comprises:

(A) a utility rack for a pick-up truck cargo bed which includes at least one stanchion with approximately vertical legs and a commonly connected cross member, at least one of said vertical legs and said cross member having a gusset with a shaft orifice adapted to receive a shaft of a winch;
(B) a reversible, portable winch adapted for attachment to said utility rack, which includes:
(a) a winch shaft for rotation which is inserted into said orifice of said utility rack;
(b) a take-up reel for winding and unwinding a flexible securing strap, said take-up reel being connected to said shaft and affixed thereto for rotation therewith;
(c) a flexible securing strap attached to said take-up reel at a first end thereof;
(d) a plurality of bidirectional pawl-engaging teeth located about said shaft and affixed thereto so as to prevent and permit rotation of said take-up reel and said shaft by being engaged and disengaged with said pawl;
(e) a pawl operationally connected to said teeth for engaging and disengaging thereof;
(f) winding means connected to one of said shaft and said take-up reel for winding said shaft and said take-up reel and,
wherein said shaft orifice is a securing means for temporarily securing said shaft to said utility rack so as to permit rotation of said shaft in said orifice, removal of said shaft from said shaft orifice and reinsertment thereof on an opposite side of said shaft orifice, so as to permit, in a first location, clockwise winding and counterclockwise unwinding, and in a second location being a reversed position, counterclockwise winding and clockwise unwinding;
and wherein said shaft orifice is created by a gusset of one of said vertical legs and said cross member.
