ABSTRACT:
An extensible shoring bar for bracing vehicle loads wherein telescoping tubular elements are spring biased toward an extended position for wedging the bar between the sides of a van or truck. An actuator interposed between the tubular elements includes a rotatable locking detent which automatically rotates between locking and release positions upon full retraction of the elements permitting the shoring bar to be locked in a retracted position for handling and positioning purposes, and by fully retracting the elements, the detent is automatically released permitting the elements to be expanded under the influence of a compression spring. The automatic locking and unlocking action of the actuator occurs upon sequential retractions of the tubular elements.
