ABSTRACT:
An apparatus for adjustably supporting a portion of a wheeled vehicle, which apparatus may be retracted or disengaged from a supporting surface when the wheeled vehicle is put into use. A tubular outer housing is provided for attaching to the vehicle, with second and third tubular members slidably disposed therein. A locking mechanism is provided adjacent an aperture in a wall of the second tubular member for positioning a pin in selectively alignable apertures in a wall of the third tubular member, thereby preventing relative movement between the second and third tubular members. A tension spring engaging both second and third tubular members and located within the third tubular member is provided for biasing the third tubular member toward a retracted position with respect to the second tubular member. A cranking rod and threaded screw member are also disclosed for moving the second tubular member with respect to the tubular outer housing.
