Abstract: An adjustable length cargo brace for restraining loads in semi-trailers comprising two legs, one connected to the other for through an offset collar permitting a limited pivotal and sliding movement between the two legs, a pin member on one of the legs approximate the offset collar which releaseably engages one of a series of openings positioned longitudinally along the opposite leg to engage the two legs together in a pivotally toggled action as they move into parallel contacting relation and a releaseable hook member mounted on one of the legs for engaging and retaining the other leg in parallel contacting relation.

Abstract: A dual position hand truck includes a central frame having two side rails and a toe plate. Positioned at an upper end of the central frame is a U-shaped handle bar which has a hand gripping portion and two extended legs with castered wheels attached at their respective bottom ends. The handle bar is pivotally attached to the frame by a fixed shaft and a pair of support brackets. The support brackets also allow the extended legs to slide along their length. Attached to the support brackets is a spring biased locking bar which locks the handle bar against rotational movement relative to the frame.
