Title:
PNEUMATIC JACK WITH DOWNWARD PRESSING BLADDER
Document Type and Number:
WIPO Patent Application WO/2019/139699
Kind Code:
A1
Abstract:
A pneumatic jack includes a body, a lifting arm, and a bladder. Inflating the bladder applies downward pressure on a proximal end of the lifting arm and raises a distal end of the lifting arm. Subsequently deflating the bladder has the opposite effect. A mounting block at the distal end of the lifting arm allows the pneumatic jack to be used to raise and lower an object such as an automobile through inflation and deflation of the bladder.
