ABSTRACT:
An improved adjustable height workstand having a base with a front face, a pair of upstanding support columns adjacent that front face, and an adjustable platform having a front end and a relatively planar tread surface which can be adjustably fixed at a plurality of predetermined vertical heights. The support columns include a plurality of vertically spaced and rearwardly extending adjustment slots, and the adjustable platform includes a pair of oppositely disposed adjustment members located adjacent the front end of the platform. The adjustment members each include an outwardly extending locking pin and a second locking member. The pin is selectively received in a corresponding adjustment slot and also enables rotation of the adjustable platform relative to the support columns. When the platform is in substantially horizontal, or use, position, the second locking member contacts a rearward facing portion of the support column to rigidly hold the tread surface against further rotation. When vertical adjustment is desired, the support platform is rotated upwardly and toward the front of the workstand to release the second locking member and enable vertical adjustment of the platform, whereby the pins can be moved to other adjustment slots, as desired.
