Abstract: A rope winding device having a spool rotatably coupled to the device for receiving the rope, a drive motor attached to the device for rotating the spool to wind the rope on the spool and a solenoid coupled between the device and the spool for selectively moving the spool axially into and out of engagement with the drive motor for selectively rotating the spool. A switch is provided in the rope eyelet for automatically causing the motor to stop when the line is reeled in to its maximum extent. The device includes a stop member on the ski rope for preventing the weight of the towed load to be placed on the spool and includes a friction member for braking the spool and preventing free rotation thereof.

Abstract: An improved mobile mount system including a vertical support member, an object mount slideably coupled to the vertical support member and a constant force member mounted at the top of the vertical support member and coupled to the mount to provide a constant force thereto for lifting an object place down.

Abstract: A mount system for a bicycle or other object of similar characteristics is disclosed. A bicycle is secured in a mount that is attached to a motor-driven band within a track. The mounted bicycle is moved along the track when the motor drives the band.
