Patent number: 6553793Abstract: A motorcycle disc brake lock includes a lock body, a rotary base, a deadbolt, a locking card, a coil spring, a lock column and a twist spring. In using, a key is applied to turn around the rotary member of the lock column to actuate the rotary base rotate. The engage members of the locking card are guided and actuated to move up and get into the engage recesses of the rotary base by the sloped surfaces of the two prop projections in the chamber of the lock body. Thus, the deadbolt is moved upward, forming an unlocked condition. For locking, only insert the disc brake of a motorcycle into the deep opening of the lock body to slightly push up the deadbolt and force the locking card to move into the slide slots of the rotary base. Thus, the deadbolt is pushed down to have its bottom end inserted in a lock hole to lock the disc brake.Type: GrantFiled: May 16, 2002Date of Patent: April 29, 2003Inventor: Tian-Yuan Chen
