ABSTRACT:
An adjustable support device includes a housing secured on a base, a platform pivotally secured to the housing for supporting a level facility. A threaded member is rotatably supported on the base, a motor is coupled to the threaded member to rotate the threaded member relative to the base. A follower is threaded to the threaded member and pivotally coupled to the platform with a link, to allow the platform to be rotated toward and away from the housing by the motor. A receiver device is received in the housing, and a remote control device may emit control signals to the receiver device, to control the motor to rotate the threaded member, and to rotate and to adjust the platform toward and away from the housing.
