Abstract: A combination lock device with latch bolt includes a combination lock, a rotary rod means, a faceplate, a securing seat, a turning means, a slide piece, a latch bolt and a housing. In order to unlock the combination lock, number dials are turned to a preset code number so that a lock hook disengages from a retain slot of the faceplate. The user may then turn the combination lock counter-clockwisely to cause the turning means to turn therewith, so that a connecting piece at a bottom side of the rotary rod means also rotate, causing a notch of the connecting piece to push a post of a turning piece to displace through 90 degrees. A slide piece is caused to displace forwardly as a result of the post pushing a slide slot, so that a movable pin on two U-shaped indentations of the slide piece displaces upwardly and then downwardly by means of a spring, causing the latch bolt to retract into the housing. Locking may be achieved by reverse operation.

A lever and a hook are interlocked to each other and pivotably mounted to the plate. The lever is movable between a closed position and an opened position such that movement of the lever from the closed position to the opened position pivots the hook and consequently unlatches the latch mechanism for the glove compartment. When the lever is in the closed position, the hook may be pivoted independent of the lever.

Abstract: A snap-latch mechanism for releasably connecting two components comprises a male latch member extending from a first component and a female latch frame disposed on a second component. The latch frame defines a passageway through which the latch member is inserted, and the latch member undergoes a torsional deflection as it passes therethrough to achieve locking engagement with the latch frame. The torsional deflection is caused by two oppositely inclined ramp surfaces disposed on the interior of the lock frame to apply a camming action and rotate an enlarged head portion of the latch member as it passes through the passageway. When the head portion has passed completely through the frame, it is released from the ramp surfaces and the latch member returns to its undeformed configuration and is latchingly engaged with the latch frame.
