A locating pin is fastened to the wall of the inner sleeve such that the locating pin extends into the bar hole for enabling the inner sleeve to move axially within the bar hole. A retrieving spring is located between the inner sleeve and the outer sleeve for enabling the inner sleeve to remain outwards in the absence of an external force. The locking rod is provided with an extra portion capable of extending outwards through the axial hole of the outer sleeve. The axial hole is provided in the wall thereof with a recess in which a compression spring and an urging pin are disposed.
Abstract: A motorcycle disk brake lock comprises a first arm, a second arm, and a lock main body. A gap is located between the first and the second arms. A lock bolt is provided with a straight leg portion and a curved portion. The straight leg portion is disposed slidably in the first arm while the curved portion of the lock bolt extends toward the second arm and across the gap. A lock bolt fastening pin is disposed in a base portion of the lock main body such that the lock bolt fastening pin can be moved between a first position and a second position, and that the lock bolt fastening pin restrains the lock bolt when located at the first position. A lock having a lock cylinder and a lock core is disposed in the base portion of the lock main body such that the lock core of the lock is coupled with the lock bolt fastening pin, which can be caused to move to the first position from the second position when the lock core is located at a locking position.
Abstract: A locking device of a motor cycle disk brake has a body provided with a slot perpendicular to one of the sides of the body. A locking bolt is disposed in the body such that the locking bolt can be caused to move between a first position and a second position. When the locking bolt is located at the second position, the locking bolt seals off an end of the slot. A locking apparatus is housed in the body and is composed of a lock core capable of being caused to locate at a third position or at a fourth position at such time when the locking apparatus is in an unlocking state or in a locking state. The lock core is coupled with the locking bolt in such a manner that the axes of the lock core and the locking bolt are parallel to each other. The locking bolt and the lock core can be caused to act synchronously. When the locking bolt is caused to seal off the slot, the locking bolt is simultaneously aligned to pass through one of the heat-radiating holes of the disk brake, thereby incapacitating the motor cycle.
Abstract: A lock for incapacitating a motorcycle disk brake has a lock body containing a locking bolt, a braking bolt, and a locking and unlocking device. The lock body is provided with a slot to receive a disk brake piece of a motorcycle. The locking and unlocking device has a rotatable core capable of turning between a locking position and an unlocking position. When the rotatable core is situated at the locking position, the braking bolt is at the third position so as to confine the locking bolt to the second position. When locking bolt is situated at the second position, the slot of the lock body is sealed off so as to cause the lock body to fasten securely to the motorcycle disk brake, which is then disabled. When the rotatable core is at an unlocking position, the braking bolt moves from the third position to the fourth position so as to cause the locking bolt to move from the second position to the first position.
Abstract: An improved door bolt comprises a slide bar seat, a slide bar disposed in an axial hole of the slide bar seat, a bolt button fastened to the slide bar, and an outer seat provided with a recessed portion having two open ends and two opposite side walls. Located symmetrically in the two opposite side walls are a plurality of parallel grooves. The slide bar seat is mounted in the recessed portion such that two wings of the slide bar seat are slidably inserted into two opposite grooves. A slide bar retainer seat is provided with a retaining hole and an inner sleeve mounted in the retaining hole in such a manner that the inner sleeve can be caused to move along the direction of the longitudinal axis of the retaining hole.
Abstract: A ratchet wheel having a locking device, includes a housing, a ratchet wheel disposed pivotally in the housing in such a manner that one end of its axle couples with an external rotating object, a braking member having a shank provided at one end thereof with a wedge angle and at other end thereof with a pivot, and a lock. The pivot is coupled pivotally with the housing in such a way that it moves between a first position and a second position. When the braking member is at the first position, its wedge angle meshes with ratchet wheel. When the braking member is at the second position, its wedge angle disengages from the ratchet wheel. The lock has a lock core capable of moving between a locking position and an unlocking position. The locking position of the lock core corresponds to the first position of the braking member, while the unlocking position of the lock core corresponds to the second position of the braking member.
Abstract: A locking apparatus for use in a motor cycle stand is disclosed. The apparatus comprises a main shaft pivotally mounted in the axial hole of the motor cycle stand, a roller connected to one end of the main shaft, a roller jacket being fastened to the motor cycle body by means of a position lever and having a braking portion disposed therein, a braking device associated with the roller and the roller jacket, a locking device comprising a lock body coupled with the roller jacket and a lock core housed in the lock body, and a clutch comprising an activator and a driven member housed in the lock body and a spring member sandwiched between the activator and the driven member. The braking device housed in a roller operates in close cooperation with a roller jacket to stop the motion of the roller. The lock core can be rotated and pushed forward by a key to activate the driven member, which, in turn, locks up the roller in order to immobilize the motor cycle stand.
