Abstract: An electric door lock including: a lock housing; an operating member having a holding part and a shaft part, the shaft part able to be placed in the lock housing, the shaft part connected to the holding part, the holding part defined as a long axis; a cog wheel able to be placed in the lock housing, the cog wheel having at least one bump; a coupling plate installed on the shaft part of the operating member, the coupling plate having at least one bulge and one protruding part, with the protruding part and the long axis of the holding part designed to move in alignment with each other; a motor placed in the lock housing; three sensor switches set separately in the lock housing; operating the motor causing the bump of the cog wheel to rotate and push the bulge of the coupling plate, so that the protruding part of the coupling plate of the electric door lock installed in the required position on a left-hand door or right-hand door, selectively touches the two sensor switches adjacent to each other, so as to reach

Abstract: A guide toy vehicle is used for obtaining related knowledge of exhibit in a pleasant and interactive way. Guidance materials are transferred between different guidance systems through a wireless network. Thus, a user can have a wide, easy and effective learning.

Abstract: A lockset includes an electric actuator which is disposed within an inside drive assembly and which has an actuator rod extending axially and movably into an outside drive assembly. The outside drive assembly has an outside sleeve connected to an outside handle and receiving an outside spindle. The outside sleeve has an axial cutout, whereas the outside spindle has an axial notch aligned with the cutout. A clutch element extends transversely from the actuator rod into the cutout and is movable within the cutout toward or away from a cutout bottom for sliding into or away from the notch so that the outside spindle and the outside sleeve are co-rotatable or not co-rotatable.

Abstract: A lock assembly includes a mounting cap with a spindle hole, a spindle extending through the spindle hole, and a rotary knob connected to the spindle. The spindle may be moved axially so as to be locked against rotational movement relative to the mounting cap. In a preferred embodiment, the mounting cap and the spindle are provided respectively with interengageable first and second engaging elements. A retaining element is mounted on the mounting cap to releaseably and selectively engage first and second shoulder faces formed on the spindle so as to retain the spindle in two positions.

Abstract: This invention is related to a lock construction comprising: an active driving mechanism, a clutch mechanism, a first latch, a first latch-driving member, a second latch, a second latch-driving member, a latch spring, a transmission mechanism, and a handle mechanism. In one embodiment, the lock construction comprises a clutch mechanism that can be activated electrically to allow latching or unlatching of the door. In an alternative embodiment, the lock construction comprises a transmission mechanism that can drive two latches of the lock simultaneously to latch or unlatch the door.

Abstract: An electrically operated lock including a latch mechanism, a spindle for displacing a dead bolt of the latch mechanism, and an actuating unit which includes a swing member, a slider, a first cam mechanism, a wheel member, a second cam mechanism, and a motor for actuating the spindle. The swing member coacts with the spindle and swings along with rotation of the spindle. The slider coacts with the swing member and is movable between a first and a second position. The first cam mechanism coacts with the slider and the swing member so as to move the slider between the first and second positions in a manual operation mode. The wheel member coacts with the slider. The second cam mechanism coacts with the slider and the wheel member so as to move the slider between the first and second positions in an electrical operation mode.
