Abstract
A lock assembly comprising a housing, a control mechanism, one pin or two pins supported by the housing for shifting movement of the pin or of the two pins in a direction transverse to direction of movement of the control mechanism between a locked position and an unlocked position and a spring for each pin for enhancing the shifting movement of the corresponding pin toward the unlocked position and for automatically returning the corresponding pin toward the locked position upon release of the control mechanism. When the control mechanism is pushed manually, the pressure which is exerted upon pushing the control means compresses the spring around the pin or two pins which each shifts in a direction transverse to direction of movement of the control mechanism between the locked position and the unlocked position. Meanwhile, shifting of the pin or of the two pins permits the sliding of a cut-out section of the control mechanism until the pin or pins strike against the cut-out sections of the control mechanism. As soon as the movement is stopped, the pin or two pins which are acted on by the spring assume a position which assures locking. As soon as the control mechanism is released, the pin or two pins immediately and automatically return to the locked position again.
