Abstract: A portable rotation assist device is configured to reorient mobility impaired patients when they are moving from one location to another such as from a vehicle seat to a wheelchair. The rotation device is placed on the floor or ground between the two positions. The patient stands or can be assisted to stand on the platform on top of the device. The platform is then rotated to a second position to transfer the patient. Rotational movement and torque is provided by an onboard battery and compact motor acting through gears incorporated into the rotating platform. Choice of rotation direction and actuation of start and stop is provided by a wireless remote control. Remote control buttons are configured so they must be held down during rotation and rotation stops upon button release.

Abstract: This patent is for a clamping mechanism for a two wheel panel dolly which is operated by turning a handle attached to the wheel axle. A threaded section of the axle is engaged with a threaded base clamp so that axle rotation drives the clamp along the axle to firmly grip a panel between the driven clamp and a the face of second clamp. Clamps are configured with different spacing between faces on opposite sides of the axle so that a wide range of panel widths can be accommodated with a relatively short clamping travel distance.
