A door locking device including a rotary part including a first rotary part and a second rotary part allowed to be changed into a locked state or an unlocked state through rotation; an elastic rotary part rotated by movement of a locking body moved by a key; a cam lever moved by rotation of the elastic rotary part; a clutch pushed and moved by movement of the cam lever; and an interlocking member inserted into the rotary part by movement of the clutch to interlock the first rotary part and the second rotary part is provided.

A motor vehicle door lock which is equipped with a locking mechanism that consists essentially of a rotary latch and a pawl. The lock also comprises a pawl spring for action on the pawl in the closing direction. The motor vehicle door lock further comprises an actuating lever for opening the locking mechanism. The actuating lever is additionally designed to act upon the pawl spring.

A lock for a closure element and comprises a locking-mechanism arrangement having a latch, a catch and a catch-switching lever, wherein the latch can be pivoted, about a latch axis, into at least one locking position, in each of which it is retained in engagement with a locking part, and into an open position wherein the catch can be pivoted into an engagement position, in which the latch located in the respective locking position is locked by the catch so that it cannot pivot, about a catch axis, in its opening direction, and a disengagement position, in which the catch frees the latch in its opening direction, and wherein the catch-switching lever can be pivoted, about a catch-pivoting-lever axis, into an actuating position, in which a sensor is activated by the catch-switching lever, and into a neutral position, in which the sensor is not actuated by the catch-switching lever.

An anti-barricading turn hub assembly is configured for use with a lockset including a bolt movable to lock and unlock a door. The anti-barricading turn hub assembly includes a spindle connected to a thumb turn on one side of the lock. The spindle is releasably engaged to a turn hub that is operable by the key from the other side of the door. Under normal operation, the spindle and turn hub rotate together to lock and unlock the bolt. In a barricading situation in which the thumb turn is held to prevent the turn hub assembly from rotating, the turn hub disengages from the spindle upon application of sufficient force through rotation of the key, and the disengaged turn hub can be rotated to unlock the bolt even if the thumb turn is held to keep the spindle from rotating.

A shelf assembly includes a receptacle having first, second, third, and fourth lateral sides and a receptacle floor defining a compartment. The shelf assembly also includes a shelf configured to engage the receptacle at the second and third lateral sides and slide along the second and third lateral sides between a closed position to thereby cover and hide the compartment and an open position to thereby expose the compartment. The shelf assembly additionally includes a sequential multi-stage lock configured to control access to the compartment.

A motor vehicle door lock which is equipped with a locking mechanism that consists essentially of a rotary latch and a pawl. The lock also comprises a pawl spring for action on the pawl in the closing direction. The motor vehicle door lock further comprises an actuating lever for opening the locking mechanism. The actuating lever is additionally designed to act upon the pawl spring.

A locking structure for a cover covering a handle seat may include a cover placed to cover a disk-shaped handle seat mounted on a surface of a door and may include a cover locking mechanism, a handle seat-side locking portion, and a rotation prevention mechanism. The cover locking mechanism may include a plurality of protrusion-shaped cover-side locking portions protruding inward at circumferential intervals at an opening end edge of the cover. The handle seat-side locking portion may include a groove portion and a hooking groove portion to which the cover is hooked when the cover-side locking portion is inserted when the cover placed is rotated. The rotation prevention mechanism may include a biased latch arranged at the groove portion. The latch may have an engagement portion projecting and retracting with respect to a bottom surface of the groove portion.

A sash window fastener includes: a latch assembly; a sash lock assembly mounted upon the meeting rail; and a stop member mounted to the master window frame. The lock assembly includes a pivotable cam to engage a keeper on the master frame to lock the window, and a pivotable follower arm. The arm interconnects with the latch assembly within the meeting rail, so cam rotation that drives arm rotation also causes translation of the latch. The cam may occupy: an extended position to secure the cam to the keeper, with the latch engaging the master frame to prevent tilting, and being positioned below a protrusion on the stop member to redundantly lock the window; a first retracted cam position permitting sliding of the window; and a second retracted position permitting tilting of the sash window. Additional protrusions may be used on the stop member to serve as vent stop positions.

An anti-barricading turn hub assembly is configured for use with a lockset including a bolt movable to lock and unlock a door. The anti-barricading turn hub assembly includes a spindle connected to a thumb turn on one side of the lock. The spindle is releasably engaged to a turn hub that is operable by the key from the other side of the door. Under normal operation, the spindle and turn hub rotate together to lock and unlock the bolt. In a barricading situation in which the thumb turn is held to prevent the turn hub assembly from rotating, the turn hub disengages from the spindle upon application of sufficient force through rotation of the key, and the disengaged turn hub can be rotated to unlock the bolt even if the thumb turn is held to keep the spindle from rotating.

A latch having: a fork bolt movably mounted to the latch for movement between an open position and a closed position; a detent lever movably mounted to the latch for movement between a latched position and a released position, wherein the detent lever prevents the fork bolt from moving from the closed position when the detent lever is in the latched position; a hold open lever configured for movement between a first position and a second position wherein the hold open lever has a feature configured to engage a feature of the detent lever such that the detent lever is retained in the disengaged position by the hold open lever when it is in the first position, wherein the hold open lever moves in a plane or directions that are angularly oriented to a plane or directions in which the fork bolt and the detent lever move.
