  • Lock mechanism for a cycling vehicle
    Patent number: 5069049
    Abstract: A lock device includes a latch part and a block fixed to the fork portion of a motorcycle. A frame is engageable between the latch part and the block so as to lock the wheel of the motorcycle. The frame is rotatably coupled to a pair of supports which are rotatable about the block. When the supports are latched by a latch pin, the frame can be maintained in parallel to the fork portion so that the wheel is free to rotate. When the supports are released, the frame is rotatable and the free ends of the frame can be locked by the latch part. The lock device can be easily operated.
