ABSTRACT:
Latch mechanisms for latching two bodies in both tension and shear. A longitudinally extending latching bolt is associated with a latching assembly having an overcenter link mechanism controlled by a lever. The overcenter link mechanism includes a slot cooperating with a pin to provide two effective lengths to the fully extended linkage. A laterally extending notch provides a shoulder intermediate the ends of the slot to receive the pin. A keeper is slidably associated with a keeper assembly to engage the longitudinally extending bolt to prevent its withdrawal from the keeper assembly. Inclined surfaces between the latching bolt and the keeper function to engage or disengage the spring biased keeper with movement of the latching bolt in a preselected direction.
