ABSTRACT:
A landing gear assembly for use in supporting a semitrailer basically includes a main body and a leg axially extensible from the main body. An expansible membrane disposed within the main body is provided for displacing the leg to an extended position. A restrictive passage through the main body limits the travel of the leg through the main body. Upon compressing the expansible membrane, a biasing element disposed within the main body is provided for urging the leg back to a retracted position. The leg may be releasably secured in either an extended or retracted position.
