  • Patent number: 9169863
    Abstract: A latching apparatus for sequentially latching and unlatching two objects is provided. The latching apparatus includes a cylinder attached to the first object and including a first opening, and a second opening laterally disposed to the first opening, a spring loaded piston including a circumferential wall disposed in the first opening, a shank axially extending from the piston and defining a transverse latch pin at an end thereof, and a spring loaded plunger disposed within the second opening. The wall defines a contiguous cam-groove thereon. The cam-groove includes alternating upper and lower nodal points with straight and inclined segments therebetween. The plunger slidably engages the cam-groove to co-operatively execute one or more of a translation, and a rotation of the shank such that the latch pin rotatably extends or retracts into or out of the slotted opening on the locking plate of the second object.
