Abstract: A car seat base with a lock position indicator mechanism, includes at least two locking units, an indicating unit and an associating unit. The locking units are mounted inside the base, each has a locked position for locking a car seat thereupon, and an unlocked position that permits the car seat to be released from the base. The indicating unit provides a first color area and a second color area for indicating the positions of the locking units. The associating unit is associated between the locking units and the indicating unit; when all of the locking units have been moved to the locked position, the associating unit associates the indicating unit to reveal the first color area; and when one of the locking unit is failed to move to the locked position, the associating unit associates the indicating unit to reveal the second color area.

Abstract: A warning device for a car seat base includes a car seat base, a support leg and a color signal revealing mechanism. The car seat base is capable of mounting on a vehicle seat and provided with a support face for supporting a car seat thereupon and a signal window for showing signals by colors. The support leg is movably and rotably mounted to the car seat base. Once the length of the support leg is not yet good enough to abut the car seat base, or someday the lock means of the support leg is failed, the weight of the support leg would carry itself moving downward, by this way to cause the signal element to reveal a warning signal from signal window to the user.

Abstract: A car seat base with a self-keeping lock mechanism for releasably locking a car seat rested thereon. The car seat has a pair of rods fixed at its underside, and the self-keeping lock mechanism is characterized by including at least a front hook element and a rear hook element and at least a front positioner and a rear positioner. The front hook element and the rear hook element are spaced apart from each other and pivoted inside the car seat base for locking the rods in a closed position, and releasing the rod in an opened position; the front positioner and the rear positioner are pivoted near the hook elements for keeping the hook elements in the opened position before the rods being entered into and caught by the hook elements, and may keep the hook elements in the closed position when the rods have been locked by the hook elements.

Abstract: A baby car seat with a two-use release mechanism includes a baby car seat releasable from a mobile rack and base by pulling a handle in same place and same direction at one end of the baby car seat. The baby car seat is equipped with a set of first hooks for releasably anchoring on a mobile rack to use as a baby seat-stroller, a set of anchor rods for engaging by a set of second hooks 31 to be connected to a base for installing on a vehicle seat without the troublesome of tying and untying safety seat in the vehicle, and a set of sliding shifters for disengaging the set of second hooks from the set of anchor rods so as to release baby car seat from the base.

Abstract: A door lock includes a first driven wheel connected drivenly to a motor and having two resilient driving elements, and a second driven wheel connected drivenly to a rotary handle and the first driven wheel. The second driven wheel has a driven element disposed between and driven by the driving elements so that the second driven wheel moves to a first or second position to place a latch bolt in a latching or unlatching position. When the latch bolt is jammed, the second driven wheel is inoperative. However, as the driving elements are resilient, the first driven wheel can continue its rotation without being obstructed.

Abstract: An electric door lock includes a transmission wheel driven by a motor and incorporating a spring with a driving end to drive a driven wheel. The transmission wheel and the driven wheel are rotatably sleeved around an inner drive tube connected to an inner handle. A spindle is inserted into the inner drive tube and has an operating end exposed from the inner handle. The driven wheel is connected integrally to the spindle for rotation. Preferably, a coupling piece extends through an arc-shaped slot in the inner drive tube and interconnects the driven wheel and the spindle.

Abstract: In a door lock assembly, a push/pull handle is connected to a slide plate through an actuator. When the handle is operated, the actuator drives a rotary cam to rotate a spindle tube, which in turn operates a latch cam connected to a latch. The slide plate is mounted movably within a housing in proximity to the rotary cam to slide transversely of a rotation axis of the spindle tube, and has two drive elements to respectively drive two driven elements of the rotary cam. The actuator is formed as a strip having one end connected to the handle, and another end connected to the slide plate. The strip is pivotal along with the handle to actuate the slide plate.

Abstract: A latch-bolt mechanism includes a housing, a latch-bolt, and a distance-adjusting device. The latch-bolt is movable relative to the housing between an extended position and a retracted position. The distance-adjusting device includes a movable unit movable in the housing between first and second vertical positions and including a first drive member for driving movement of the latch-bolt from the extended position to the retracted position when the movable unit is disposed at either the first or second vertical positions, and a fastener unit for locking the movable unit releaseably at a selected one of the first and second vertical positions.

Abstract: A method to incorporate specific numeric values queue with image retrieval and reproduction includes sort and generating a result; image being retrieved and stored once the result meets preset condition; and in the course of sorting, image retrieved being present at the same time corresponding to the result on a display unit for making sorting process more fun and lively.
