Abstract: A press-buckled lock having a press buckle is used so that the operation of locking and unlocking can be performed rapidly. By pressing the buckle, the door can be locked rapidly. When the inner handle is rotated, the press buckle is separated rapidly to unlock. Other than making the operation easy, the installation of the press buckle at the inner handle of a lock will reduce the manufacturing cost and cause the operation to be easy. Thereby the cost is reduced. By pressing the press buckle, a lock can locked rapidly; when rotating the inner handle or inserting a specific key into the lock core, the press buckle will separate rapidly so as to unlock the lock; thus, the press buckle in the lock has the effect of controlling the locking and unlocking operation rapidly.

Abstract: A lock includes a handle, a hub, and a spindle rotatably mounted in the hub and coupled to the handle to turn therewith. A transmission member is fixed to the handle to turn therewith. The transmission member is mounted around and not rotatably engaged with the spindle. The transmission member is stopped by the hub after the handle has been turned through an angle, transmitting a torque from the handle to the hub via the transmission member. Thus, impact from the handle can be partly transmitted to the hub and then to a door on which the lock is mounted, instead of completely transmitted to the spindle. Damage to the spindle is, thus, avoided.

Abstract: The present invention provides for a locking mechanism for use in a door and the like. A remote handheld controller transmits coded signals to an electronic door lock. A sensor/receiver receives the signals and provides the signal to a processor which compares the coded signals against a predetermined stored signal. If the received coded signal matches the predetermined signal, then the processor generates control signals to actuate an electromechanical device, which acts solely along or about the locking axis, to enable or disable the locking latch. The user is then able to turn the door handle in a normal manner. The coded signals are comprised of two separate signals which are transmitted in segments interleaved with one another. The first signal includes an entrance code, while the second signal provides information concerning the frequency over which the next segments will be transmitted. The processor uses the second signal information to tune the receiver.
