A latch mechanism includes a hook-handle assembly coupled to a first panel and a clevis coupled to a second panel. The hook-handle assembly engages the clevis to secure the first panel relative to the second panel.

A sliding door unit has a mounting frame and an active door panel mounted in and capable of sliding relative to the mounting frame. The active door panel has a face including a panel portion and a glazing portion. The glazing portion comprises less than 65% of a surface area of the face.

A sliding door locking system includes a sliding door having an inner surface that slides over a doorway opening when the door is slidably mounted above the doorway opening, and an outer surface. A lock housing is mounted in the sliding door, the housing having an aperture extending through the inner surface of the sliding door. A latch is hingedly mounted in the aperture such that the latch is moveable from a retracted position, in which the door is slidable along the door opening, and an extended position, in which the latch engages a catch opposite the inner surface of the door and adjacent the doorway opening. At least one of the inner and outer surfaces of the sliding door includes an actuator that, when moved from a first position to a second position, moves the latch from the retracted position to the extended position.

A ball lock includes a body having a shaft with at least one retention feature disposed at a distal portion of the shaft. The body of the ball lock may also define a central chamber and an access slot open to the central chamber. The ball lock may include a spindle disposed within the central chamber of the body. The spindle may be in either a locked position or an unlocked position. The ball lock may further include an indicator coupled to the spindle and viewable to a user via the access slot, wherein the indicator is configured to indicate to the user whether the spindle is in the locked position or the unlocked position.

Cylinder assembly with rotating winged latch bolt for sliding door lockset includes a special latch bolt that holds in an extended position and holds in a retracted position which alternates back and forth by pressing the latch bolt with your finger. The special latch bolt rotates ninety degrees by turning the doorknob, door handle, thumb turn, or coin turn and rotates back ninety degrees by turning the doorknob, door handle, thumb turn, or coin turn back. The special latch bolt has a special winged shape that catches within the strike plate when rotated ninety degrees and releases from the strike plate when rotated ninety degrees back. Also there is a special face plate or cylinder face plate with tabs or notches that serve as a two-position mechanical stop to prevent the latch bolt from over rotating beyond ninety degrees in either direction.

The present invention discloses a motored locking mechanism, comprising a motor, two groups of transmission mechanisms that are arranged mirror symmetrically and two output components that are arranged mirror symmetrically, wherein the transmission mechanisms transfer power of the motor to the output components, wherein the motor is provided at an output end with a driving gear, wherein the driving gear is attached to an output shaft of the motor. The transmission mechanisms on two mirror sides are controlled by a common motor so the volume is smaller with a simpler structure. Regarding both sides of the lock, the transmission mechanism of one side is driven wherein the other side not. Thus, two unrelated systems are driven by a single motor.

The present invention discloses a cylinder and a control component and relates to the field of locks, comprising two mirror-symmetric cylinder mechanisms which jointly drive a latchbolt control ring. The present invention enables equal operations on both sides of a door, and that the separate operation on both sides of the door does not interfere with each other. Furthermore, only one cylinder is required, which simplifies the structure and a single motor realizes a not-interfered alternating output on both sides of the door.

A latch arrangement may comprise a latch bolt configured to rotate about a pivot, and a shear pin coupled to the latch bolt. A counterbore may receive the shear pin whereby lateral loads may be transferred between a door panel and a frame.
