  • Trampoline assembly tool
    Patent number: 5477599
    Abstract: A tool for attaching springs to a trampoline mat, and a method for using the tool to assemble a trampoline. The tool has a straight rigid shaft and a curved rigid handle connected and separated by a rigid plate. The handle is curved to fit the closed hand of a user, and the plate prevents accidental contact of the spring with the user's hand regardless of the orientation of the tool. One end of each spring is connected to the frame of the trampoline. The other end of the spring is slipped over the straight shaft of the tool, then attached to one of the "D" rings on the mat. By pushing the tool away from him or her, the user causes the spring to slide down the shaft and hook onto the "D" ring. The process is then repeated for the other springs and "D" rings.

  • Device for attaching a prosthesis
    Patent number: 5203791
    Abstract: A device for attaching a prosthesis to an above-the-knee amputee. The device includes a frame which is vertically adjustable for different working heights. A motor is mounted on the frame, and is controlled by a switch. One end of a shaft is connected to the motor, which turns the shaft. The other end of the shaft is disposed in a bearing supported by the frame. A clip holds one end of a tubular stocking in contact with the shaft. As the shaft turns, the stocking is wrapped around the shaft, drawing the stocking toward the shaft.
