Locking device for the opening of a door including two opposite members apt to be mounted to a door and to a post, respectively, and provided with housing holes of screws for the engagement with a surface, one of the bodies including a solid body except for a cavity provided on one of the side walls, the other one of the bodies including an outside shell internally provided with a housing cavity of a sliding body, characterised in that a lock block for the movement of the sliding body is furthermore provided, housed within a cavity provided on the top surface of the outer shell as well as dampening and thrust structure of the sliding body.

A latch mechanism includes a first and second latch body. The first and second latch body respectively includes a first and second base, a first and second latch portion and a first and second acting portion. The first latch body disposes through the second base. The second acting portion is pivoted to the second base. The second latch portion is disposed on the rotational path and limited to the first latch portion. The second acting portion includes a first and a second pushing structure. When the second acting portion is rotated along the rotational path, the second latch portion is pushed by the first pushing structure such that the second latch portion is disengaged from the first latch portion, and then the first acting portion is pushed by the second pushing structure such that the first latch body is disengaged from the second latch body in a releasing direction.

A safety lock and access key for doors that otherwise need to remain locked comprising a lock body containing a spring biased catch extending from one end of the body to engage in a keep of the door frame, a lever for moving the catch into the body to unlock the door, and a tool for unlocking locked doors.

A collinear latching and locking system is disclosed. In embodiments, the system includes a strike with a lock bolt disposed at or defined by an end of the strike. The system further includes a latch pawl configured to surround at least a portion of the strike. The strike and the latch pawl are configured to actuate linearly along the same axis. In this regard, the strike and the latch pawl have a collinear configuration and actuation path. The system further includes a latch cam configured to actuate the latch pawl from a latched position to an unlatched position when the latch cam is turned.

The present oblique slide latch apparatus includes a housing, lever, and latch. A straight channel is positioned obliquely on the latch and is oblique relative to an axis along which the latch slides. The lever includes first and second pegs that capture inner and outer portions of a latch head to minimize wobble of the latch. The latch head is positioned within opposite sides of the lever.

An exemplary torque-limiting spindle includes an input member, an output member, a clutch mechanism, and a bias mechanism. The input member extends along a longitudinal axis, is configured for connection with a handle, and includes a first engagement feature. The output member extends along the longitudinal axis, is configured for connection with a rotatable member of a lockset, and includes a second engagement feature. The clutch mechanism includes the first engagement feature and the second engagement feature. The bias mechanism is engaged with the input member and the output member and exerts a biasing force urging the first engagement feature and the second engagement feature into engagement with one another.

A latch feature for a door is disclosed herein. The latch feature includes an input body that is operable to move linearly between first and second positions relative to the door. The latch feature also includes an output body. The output body is coupled to the input body by a pivot member that is configured to pivot relative to the output body and the input body to allow the output body to move linearly toward the input body from an outboard position to an inboard position as the input body moves from the first position to the second position.

A shielded locking system for securely closing a lid on an enclosure, such as a grade level utility vault, including an L-bolt connected to a spring-biased slide member positioned on the underside of the lid that rotates in a slotted housing that securely retains the L-bolt under the lid, the slide member engaging an abutment on the inside of the enclosure when the lid is forced down over an opening in the enclosure by downward force on the lid which progressively causes the latch to retract against the spring-bias from contact with the abutment and then snaps the latch into a spring-biased locking position under the abutment, and a non-conductive cover positioned over and connected to the locking system to shield the L-bolt from electrical conductivity from within the enclosure.

A latchbolt retractor (12) is described herein. The latchbolt retractor (12) comprises a latchbolt retraction mechanism (30) mounted to a carriage (28). The latchbolt retraction mechanism (30) comprising a latchbolt assembly coupler (32) for operational coupling to a latchbolt assembly (22). The carriage (28) is configured to slide along at least one rail (14,16) for positioning the latchbolt assembly coupler (32) relative to the latchbolt.

The present invention relates to an improved carabiner system, including an impact-dampening cushion around the external surface of the frame for cushioning damage during a fall or collision and to reduce sound from loose or swinging carabiner collisions. Additional surface routing and through holes provide improved register between the carabiner frame and the over-molded cushion layer.
