CA 2127382

A novel jackable prop or stand is provided herein. It includes a base including a transverse plate and a pair of widely spaced-apart, forwardly-projecting feet. A pair of spaced-apart, perforated posts,"I"-shaped cross-section upstand from the base, each such post having a plurality of vertically-spaced-apart apertures through the web. A freely-vertically-movable riser assembly is slidably, but not relatively rotatably-mounted on the posts. The riser assembly include a pair of bushings, each having an "I"- shaped cross-section complementary to the posts, and a pair of forwardly-projecting, load-bearing lifting arms operatively associated with the transverse bar at the vicinity of the bushings. A spring-biased pin is adapted to be manually manipulated to allow automatic removal from and entry into, the next vertically-higher aperture in the associated web to hold the riser assembly in a raised position and to allow locking of the pin in an associated aperture in the web. That pin is adapted to be manually rotated through 180° to permit the pin to be urged out of the apertures to lower the load. Engagement plates are provided on the base and on the transverse bar to be engaged by a jack. Operation of the jack causes the riser assembly and hence the transverse bar and the load bearing lifting arms, to be raised against a load and to be automatically held there. The riser assembly can be lowered by rotating the spring-loaded pins.
