Abstract
A winch bar for use with tie-down strap winches has an elongated bar member, an insert member attached to the bar member, a bar pawl pivotally attached to the bar member and a spring to bias the bar pawl toward the insert member. The bar pawl abuts the insert member when the winch bar is in a closed position. The spring is disposed between a first spring connector attached to the bar member and a second spring connector attached to the bar pawl. With the insert member engaged in the strap winch, the winch bar winds the strap winch winding drum by operatively engaging the strap winch ratchet wheel when pivoted in the tightening direction. When pivoted in the opposite direction, the bar pawl ratchets against the ratchet wheel to allow winding of the winding drum without having to remove the winch bar from the strap winch.
