Abstract
A winch bar has an insertion portion adapted to fit in openings of a winch drum of non-circular cross-section, typically square or hexagonal, whereby the winch bar cannot rotate relative to the openings to present hazards of injury to persons or property which can result with prior art circular drum openings and circular cross-section bars.
Claims14
A winch bar and winch drum combination, comprising:
- a winch bar insertion portion having a polygonal cross-sectional configuration adapted to fit in openings of similar cross-sectional polygonal configuration in a winch winding drum, and
- an elongate handle portion of the winch bar disposed at an acute angle relative to the insertion portion for manual grasping thereof for manipulation to rotate the winch winding drum to exert tension force on a retaining strap secured on the winding drum to retain objects secured by the strap,
- whereby with said winch bar insertion portion of polygonal cross-sectional configuration engaged in similarly configured diametrically opposite ones of said openings of the winch winding drum, relative rotation between the winch bar and the winch winding drum openings is prevented to prevent the winch bar from swinging about the winch winding drum openings in a generally conical pattern, thereby preventing injury to persons and damage to property.
A winch bar and cooperating ratchet drive winch combination for exerting securing tension force on at least one winding strap to secure at least one object on a vehicle, said winch bar comprising:
- a winch bar insertion portion for insertion into diametrically opposed polygonal openings in an annular drum of said ratchet drive winch,
- an elongate winch bar handle portion disposed at an angle relative to the insertion portion,
- said winch bar insertion portion having a polygonal cross-sectional configuration adapted for cooperation with said annular drum polygonal openings to engage and fit therein to prevent relative rotation between the winch bar and the drum openings,
- whereby rotation of the winch bar relative to the annular drum is prevented with no rotation of the bar handle portion in a swinging pattern, whereby hazards to persons and property are prevented, and
- whereby manual manipulation of the handle portion to rotate the winch drive exerts tension force on the at least one winding strap to exert restraining force on at least one object on the vehicle.
