Abstract: A device for controlling motion of an object includes a housing defining first and second cavities each extending from a first to a second longitudinal end of the housing. A partition separates the cavities. A first sliding member is movable within the first cavity, and includes a first extension extending outwardly from the first longitudinal end for being attached to an object whose movement is to be controlled. A second sliding member is movable within the second cavity, and includes a second extension extending outwardly from a longitudinal end for being pulled a variably controlled distance away from the housing. A motion limiting member communicates with the sliding members such that movement of the second extension the variably controlled distance away from the housing causes the first extension to be movable the variably controlled distance in a direction in which the second sliding member is pulled.

Abstract: A device for controlling motion of an object includes a housing defining first and second cavities each extending from a first to a second longitudinal end of the housing. A partition separates the cavities. A first sliding (controlled) member is movable within the first cavity, and includes a first extension extending outwardly from the first longitudinal end for being attached to an object whose movement is to be controlled. A second sliding (controlling) member is movable within the second cavity, and includes a second extension extending outwardly from a longitudinal end for being pulled a variably controlled distance away from the housing. A motion limiting member communicates with the sliding members such that movement of the second extension the variably controlled distance away from the housing causes the first extension to be movable the variably controlled distance in a direction in which the second sliding member is pulled.
