International ClassB60P 007/15AbstractA cargo load bracing bar comprises first, outer and second, inner telescoping tubular members, a housing attached to the outer tubular member, a pinion gear and actuating ratchet handle, having a spring-biased ratchet member mounted thereon, respectively rotatably and pivotally mounted upon the housing, and a gear rack attached at one end thereof to the inner tubular member while the opposite end of the gear rack is slidably disposed upon the outer tubular member. An angle bracket is mounted upon the housing, and a spring-biased pawl member is slidably disposed upon the gear rack and operatively associated with the angle bracket. The pawl member and the ratchet member are normally engaged with the pinion gear so as to achieve the ratcheting extension of the gear rack and the inner tubular member with respect to the outer tubular member. However, the ratchet member may be disengaged from the pinion gear so as to permit the ratchet handle to be moved to a collapsed position substantially parallel to the outer tubular member, and both the ratchet member and the pawl member may be disengaged from the pinion gear so as to permit the pinion gear to freely rotate, and the gear rack and inner tubular member to undergo free longitudinal movement, so as to permit the cargo load bracing bar to be rapidly extended or contracted.Other References
