Patent ID: 7607704

Claim:
A latch bolt mechanism comprising: (a) an elongated housing defining a bolt channel for receiving a bolt and transverse spindle opening for receiving two spindles; (b) an elongated bolt having a transverse bore extending through the bolt defining two inclined spindle bearing surfaces, the bolt being slidably mounted within the bolt channel of the housing for movement between an extended position and a retracted position; (c) two spindles each with a leading inclined engagement surface, slidably mounted through the spindle opening of the housing and passing through the transverse bore of the bolt, the spindle being slidably mounted for movement between a disengaged position with the inclined engagement surface of a spindle operatively abutting a corresponding inclined spindle bearing surface of the bolt when the bolt is in the extended position, and an engaged position wherein the inclined engagement surface of a spindle operatively engages a corresponding inclined spindle bearing surface of the bolt to cause the bolt to move to the retracted position; and (d) a spindle bias means retained within a cavity in the surface of each spindle for biasing each spindle into its disengaged position.
