Push pull latch bolt mechanism

A latch bolt mechanism comprising:

• a. an elongated housing with a transverse opening for receiving two opposing spindles;
• b. an elongated bolt having a transverse opening for receiving two spindles with opposite facing inclined surfaces defined therein, slideably mounted within the housing for movement between an extended position partially extended from the housing and a retracted position fully retracted within the housing;
• and
• c. two spindles each having an inclined surface slideably mounted through the openings in the bolt and housing with the inclined surface of each spindle facing the other and in operative interaction with a corresponding inclined surface of the bolt, such that movement of a spindle actuates movement of the bolt between the retracted position and extended position.

A mortise latch bolt mechanism comprising:

• a. an elongated housing with a transverse opening for receiving two opposing spindles;
• b. an elongated bolt having a transverse opening for receiving two spindles with opposite facing inclined surfaces defined therein, slideably mounted within the housing for movement between an extended position partially extended from the housing and a retracted position fully retracted within the housing;
• c. two spindles each having an inclined surface slideably mounted through the openings in the bolt and housing with the inclined surface of each spindle facing the other and in operative interaction with a corresponding inclined surface of the bolt, such that movement of a spindle actuates movement of the bolt between the retracted position and extended position;
• and
• d. bias means for biasing the bolt in its extended position until actuated by movement of a spindle.

A mortise latch bolt mechanism comprising:

• a. an elongated housing having a transverse opening for receiving a pair of opposing spindles and further having a transverse lock guide for guiding a lock between a locked position and an unlocked position;
• b. an elongated bolt having a longitudinal side channel with a transverse recess at one end and further having a transverse opening through the bolt for receiving a pair of spindles, with the opening defining a pair of opposite facing inclined surfaces, wherein the bolt is slideably mounted within the housing for movement between an extended position partially extended from the housing and a retracted position fully retracted within the housing;
• c. a pair of spindles each having an inclined surface, slideably mounted through the bolt and housing openings from opposite sides of the housing, with the inclined surfaces of each spindle generally facing the other and each inclined surface in operative interaction with a corresponding inclined surface of the bolt, such that movement of a spindle actuates movement of the bolt between the retracted position and extended position;
• d. bias means for biasing the bolt in its extended position until actuated by movement of a spindle;
• and
• e. a lock slideably mounted to the lock guide and actuated between an unlocked position within the side channel of the bolt and a locked position within the transverse recess of the bolt.

A mortise latch bolt mechanism comprising:

• a. an elongated housing having a transverse opening for receiving a pair of opposing spindles and a longitudinal inward facing side channel with a transverse recess at one end for receiving a lock;
• b. an elongated bolt having a transverse opening through the bolt for receiving a pair of spindles with the opening defining a pair of opposite facing inclined surfaces, and further having a transverse lock guide for guiding a lock between a locked position and an unlocked position, wherein the bolt is slideably mounted within the housing for movement between an extended position partially extended from the housing and a retracted position fully retracted within the housing;
• c. a pair of spindles each having an inclined surface, slideably mounted through the bolt and housing openings from opposite sides of the housing, with the inclined surfaces of each spindle generally facing the other and each inclined surface in operative interaction with a corresponding inclined surface of the bolt, such that movement of a spindle actuates movement of the bolt between the retracted position and extended position;
• d. bias means for biasing the bolt in its extended position until actuated by movement of a spindle;
• e. a lock slideably mounted to the lock guide and actuated between an unlocked position within the side channel of the housing and a locked position within the transverse recess of the housing.
• f. means for actuating the lock between the locked and unlocked positions.
