Abstract

A latch for a door, the door being movable between an open position and a closed position with the latch securing the door in the closed position. The latch includes a base plate that is mounted to the door. The latch further includes a housing secured to the base plate and a rotating member disposed between the housing and the base plate. A knob is pivotably mounted to the rotating member and extends through the housing. The knob is operable between a folded position and an extended position. When in the knob is in folded position, the knob is received within a recessed area of the housing and is restricted from movement. When the knob is in the extended position, the knob is extended from the recessed area and operable to rotate the rotating member to slide a bolt between the bolt extended position, where the door is locked, and a bolt retracted position, where the door is unlocked and can freely move.

Claims

1. A latch for a door moveable between an open position and a closed position, the latch securing the door in the closed position, the latch comprising:

a housing adapted to be mounted to the door, said housing including a recessed area and a detent recess;

a bolt mounted to said housing and moveable between a bolt retracted position in the door open position and a bolt extended position in the door closed position;

a bolt actuator mounted within said housing and coupled to said bolt and said bolt actuator including a detent; and

a knob extending from said housing and coupled to said bolt actuator, said knob being moveable between a storage position within said housing recessed area and an extended position for moving said bolt between said bolt retracted position and said bolt extended position.

2. The latch of claim 1 wherein said knob is disposed generally parallel to said housing in said storage position.

3. The latch of claim 1 wherein said knob is disposed generally perpendicular to said housing in said extended position.

4. The latch of claim 1 wherein said knob is pivotably mounted to said bolt actuator.

5. The latch of claim 1 wherein said knob includes an extension and said housing recessed area includes a slot for receiving said knob extension in said knob storage position.

6. A latch for a door moveable between an open position and a closed position, the latch securing the door in the closed position, the latch comprising:

a base plate adapted to be mounted to the door;

a housing secured to said base plate, said housing including a recessed area and a detent recess;

a rotating member disposed between said housing and said base plate and said rotating member including a detent;

a knob pivotably mounted to said rotating member and extending through said housing;

a bolt coupled to said rotating member and slidable between a retracted position in the door open position and an extended position in the door closed position; and

wherein when said knob is in said folded position, said knob is received within said recessed area of said housing and when said knob is in said extended position, said knob extends from said recessed area and is operable to rotate said rotating member so as to slide said bolt between said retracted and extended positions.

7. The latch of claim 6 wherein said rotating member includes a rib and said housing including a stop member, such that when said rib engages said stop member further rotation of said rotating member is prevented.

8. A latch for securing a door in a closed position and opening the door in a door open position, the latch comprising:

a housing adapted to be mounted to the door, said housing having an aperture and a detent recess;

a rotating member mounted to said housing, said rotating member being disposed between said housing and the door, and said rotating member including a detent;

a bolt mounted to said rotating member and moveable between a retracted position in the door open position and an extended position in the door closed position; and

,

said rotating member including a pivotally mounted knob extending through said housing aperture and operable between a folded position and an extended position, wherein in said knob folded position, said knob is generally parallel to said housing and when said knob is in said extended position, said knob is generally perpendicular to said housing, such that said knob can reciprocate said rotating member to move said bolt between said retracted and extended positions.
