Abstract: A magnetically actuated safety lock device provides automatic locking capability to doors such as sliding glass patio doors and prevents unsupervised opening of the door by young children, thereby barring their access to dangerous environments. When the sliding door is closed, it is automatically locked. The lock device is installed in a position high upon the sliding door to prevent actuation by young children and requires no permanent modification to the door on which it is installed. The lock device consists of a locking assembly and a magnetic key. The locking assembly includes a magnetized latch assembly and a mounting bracket. The latch is held in the locked position by gravity and is only rotated into the unlocked position through the application of hand pressure or the repulsive force of the magnetic key. The doors can be unlocked from both inside and outside the door. Upon removal of either the magnetic force or hand pressure, the latch rotates back into the locked position.
Abstract: A latching apparatus controls the motion of a first member relative to a second member. The first member is reciprocally moveable relative to the second member in forward and reverse directions along the line of motion. The second member carries a latch which is movable within a plane parallel to the line of motion. The latch has a first pawl and a second pawl. The second member carries a pivot for carrying the latch so that the latch is rotatable relative to the second member about the pivot which is orthogonal to the line of motion. The latch is shiftable between first and second positions relative to the pivot. The first member bears a plurality of engagement features linearly arrayed along the line of motion. Each engagement feature has a generally forward facing first face and a generally rearward facing second face. When the latch is in the first position, it is biased for its first pawl to engage the engagement features.
Abstract: The invention is directed to a lock releasing mechanism for a container having a hinged or removable lid. A locking arm is disposed adjacent the container lid to prevent an opening of the lid, and a cable, or rigid bar, connects the locking arm to the locking mechanism. The elements of the locking mechanism comprise a slide plate to which the cable is fixed; a spring for urging the slide plate to a locked position, a guide member for guiding the slide plate, and a trigger ball which blocks movement of the slide arm in the locked position. When the container is tilted forward by a predetermined angle, the trigger ball becomes dislodged from the locking position to enable movement of the slide plate, and subsequent movement of the locking arm. When the locking arm is moved out of the path of travel for the container lid, the contents of the container may be removed. In one embodiment, a stop is provided to limit rotation of the locking bar to prevent contact with the container lid.
