Abstract: An invalid lifting device is disclosed. A mast is mounted to a frame to rotate about a vertical axis. A boom is mounted to the mast to swing with the mast and to pivot about a horizontal axis. A sling for supporting an invalid extends from the end of the boom. A first motor drives the mast to rotate and a second motor is mechanically linked with an extendible strut to raise and lower the boom. A control box is provided in the proximity of an invalid as he is seated in the sling to allow the user to select an elevational and rotational movement. A computer controls movement of the device based upon input at the control box.

Abstract: The present invention is a movable seat for arrangement with a motorized transport chair for use by a handicapped person. The movable seat is motorized to provide a lifting and pivoting capability to a person sitting thereon by their operating a hand control and includes a back that is hinge connected whereby the back can be pivoted to a seat bottom engaging attitude, lowering the seat vertical dimension appropriately. Additionally, the seat back can be provided with arms arranged to maintain a parallel attitude to the seat bottom as the seat back is pivoted.

Abstract: A wheeled transport vehicle for providing mobility to a handicapped child preferably consisting of a one-piece contoured plastic seat that is secured between side frame sections that rise and join in a high arc above a seat back portion as a hand grip area, the frame sections including arm and headrest members, with an axle member secured thereacross below the seat with ends thereof extending beyond the seat-sides that have large air inflated tires mounted on wheels journaled thereon, the frame further including a curved arm that mounts a caster thereon to provide a third point of ground contact. The present invention, in one embodiment, provides vehicle braking by appropriate movement of the pivoting handle or by stepping onto a vehicle step that is pivotally connected across the frame and connects to, pivot with, the pivoting handle, thereby moving the bar locks against both inflated tires.

Abstract: A three-dimensional lift intended for use by a handicapped person, providing him with three dimensions of mobility within a room or rooms. The invention consists of uniform channels or rails secured in parallel configuration adjacent to or on a room ceiling with a traveling bridge arranged to traverse the length of the channels, and incorporates with the bridge a head mounted to travel thereacross spanning the room or rooms with a sling suspended therefrom to move vertically, supporting the handicapped person, and includes a remote control hung from the head, accessable to and giving the handicapped person the capability to operate the device while he is seated in the sling, providing that person with three dimensions of travel that they control.
