The present invention relates to an improved spindle arrangement for a latch bolt mechanism for a hinged door, and in particular, to a latch bolt mechanism actuated by spring-loaded push-pull spindles. The latch bolt mechanism includes a bolt with an inclined surface, a housing, at least one push-pull spindle with an inclined surface, and a spring mounted on the spindle for biasing the spindle in an extended position. The bolt is slidably mounted within the housing for movement between an extended position (extended outward from the housing) and a retracted position (positioned within the housing). The spindle slidably extends through an opening in the housing and bolt, transversely aligned with respect to the line of travel of the bolt. As the spindle is pushed towards or pulled away from the housing, the inclined surface of the spindle engages the inclined surface of the bolt to actuate movement of the bolt between the extended and retracted positions.
