Patent number: 6702051Abstract: A detachable transmission mechanism for a wheel chair includes a control unit, an engaging unit, a battery unit and a transmission device. The original front wheels of the wheel chair can be detached and the hub and the pivot part are mounted to both the upper and lower frames of the wheel chair. The battery unit can be fixed to the wheel chair under the seat thereof. When a control switch is turned on, the driving wheel can rotate in a forward or a reversed direction with the wheel chair being capable of moving forward or backward. By turning the handle, a follower wheel at the bottom of the wheel chair can be rotated to allow the wheel chair making a turn.Type: GrantFiled: August 28, 2002Date of Patent: March 9, 2004Inventors: Simon Chu, Chih-Chin Hsieh, Tseng-Chien Lin

Patent number: 6695081Abstract: A build-up light motor driven car includes a car body, which is composed of a car frame and an outer shell enclosing the car frame, and a seat part. The car body is provided with a guide groove at two lateral sides thereof respectively, the guide groove having an engaging part, the outer shell having a shell chamber behind the respective guide groove. The seat part has two seat frames corresponding to the two guide grooves, the seat frames at upper parts thereof being attached with a seat cushion and at lower parts thereof connecting with a horizontal level respectively for locating a battery and the respective horizontal level at an end thereof having an engaging part. The horizontal levels is inserted into the guide grooves such that the engaging parts can be inserted into the joining parts so as to fixed to each other, and the batteries can enter the shell chambers to constitute connection of a circuit such that seat part can be joined to or detached from the car fast.Type: GrantFiled: July 26, 2002Date of Patent: February 24, 2004Inventors: Simon Chu, Chih-Chin Hsieh, Tseng-Chien Lin
