Abstract
A compression latch is disclosed that is adapted to fold down in both the locked and unlocked positions and that compresses a washer when in the closed position. The latch can couple directly to a hinged body, and does not require a separate housing that is then coupled to the hinged body. The above structure reduces leak points, creates a flush appearance, reduces the risk of injury, and allows greater customizability, as compared to prior art latches.
Claims21
A latch for selectively latching a hinged body, comprising:
- a shaft extending through an aperture disposed in a recess of the hinged body;
- a handle pivotably coupled to the shaft and adapted to be disposed in the recess on a first side of the hinged body and pivotable between upright and folded down positions;
- a first cam disposed on the shaft opposite the handle on a second side of the hinged body, the first cam adapted to be selectively rotated between locked and unlocked positions in response to rotation of the handle between respective handle locked and unlocked positions;
- a body disposed on the shaft between the first cam and the hinged body;
- a cap disposed on the shaft between the first cam and the body;
- and
- a bias member disposed on the shaft between the body and the cap and adapted to bias the cap away from the second side of the hinged body,
- wherein when the handle is pivoted to the upright position, the shaft is biased in a downwardly direction and the first cam is rotatable between the locked and unlocked positions.

A latching mechanism, comprising:
- a compression latch installed in a recess of a hinged body, the compression latch including:
- a shaft;
- a handle pivotably coupled to the shaft and pivotable between upright and folded down positions and rotatable between locked and unlocked positions;
- a lock cylinder extending through the handle and a first cam adapted to extend into the recess when the handle is in the folded down position;
- and
- a second cam disposed on the shaft opposite the handle and rotatable between locked and unlocked positions in response to respective rotation of the handle between the locked and unlocked positions;
- and
- a trim ring coupled to the hinged body above the recess and including:
- a locking tab extending into the recess, wherein the first cam engages the locking tab when the handle is in the locked position and disengages the locking tab when the handle is in the unlocked position.

A latch mechanism, comprising:
- a compression latch adapted to be disposed in a recess of a hinged body and including a handle having a lock cylinder extending through the handle and a first cam adapted to extend into the recess when the latch is disposed in the recess and the handle is disposed in a folded down position;
- and
- a trim ring adapted to be coupled to the hinged body above the recess and including a locking tab extending into the recess when the trim ring is coupled to the hinged body, the first cam adapted to engage the locking tab in a locked position and disengage the locking tab in an unlocked position.
A latch for selectively latching a hinged body, comprising:
- a shaft extending through an aperture in a recess of the hinged body when the latch is installed in the hinged body;
- a handle pivotably coupled to the shaft and pivotable between upright and folded down positions, the handle including a lock cylinder extending through the handle and a cam coupled to the lock cylinder, the cam being selectively rotatable between handle locked and unlocked positions, the handle being disposed in the recess on a first side of the hinged body and the cam extending into the recess when the handle is in the folded down position and the latch is installed;
- a first sealing washer circumferentially disposed on the shaft between the handle and the first side of the hinged body when the latch is installed;
- a second washer circumferentially disposed on the shaft between the handle and the sealing washer, the second washer adapted to prevent over compression of the first washer when the handle is in the folded down position;
- a wear washer circumferentially disposed on the shaft between the handle and the second washer;
- a latching cam disposed on the shaft opposite the handle and on a second side of the hinged body when the latch is installed, the latching cam adapted to be selectively rotated between locked and unlocked positions in response to rotation of the handle;
- a cap disposed on the shaft between the latching cam and the hinged body when the latch is installed;
- a body disposed on the shaft between the cap and the hinged body when the latch is installed, the body being adapted to receive the cap;
- a second sealing washer circumferentially disposed on the shaft between the body and the hinged body when the latch is installed;
- and
- a bias member disposed on the shaft between the body and the cap and adapted to bias the body and the second sealing washer toward the hinged body and bias the cap away from the hinged body, wherein when the handle is pivoted to the upright position, the shaft is biased in a downwardly direction and the latching cam is rotatable between the locked and unlocked positions.
