ABSTRACT:
A chair lift includes a jack movable between lowered and raised configurations and a motor in communication with the jack for moving the jack between the lowered and raised configurations. A switch is in communication with the motor to selectively actuate the motor. A mounting bracket is coupled to the jack to move vertically as the jack moves between the lowered and raised configurations, the mounting bracket having opposed first and second ends. First and second clamping mechanisms are configured for attachment to respective chair legs, the first and second clamping mechanisms being below the mounting bracket. A first flexible connecting link extends between and coupled to the mounting bracket first end and the first clamping mechanism. A second flexible connecting link extends between and coupled to the mounting bracket second end and the second clamping mechanism.
