A knob-less horizontal-shift fire door lock includes a base including a longitudinal bar, an unlocked-state positioning member arranged in the longitudinal bar and having a positioning section; a latch pivoted to the base and having a free end elastically biased outside the base to engage a keeper on a door jamb; a push board pivoted in the base; and a handle bar slidably mounted on the longitudinal bar. The handle bar is biased by an elastic element to protrude outwards and moving a guide pin to slide in a guide groove of the positioning section. The handle bar is depressible toward the longitudinal bar to move the push board to drive the latch to retract into the base to achieve an unlocked state. The handle bar is further shiftable horizontally to cause the guide pin to slide into a horizontal groove of the positioning section for being secured in position.

A lock assembly comprising: a hand-operable member configured to move laterally relative to a fore-end of the lock assembly; wherein lateral movement of the hand-operable member causes the lock assembly to move between a locked mode and an unlocked mode. A lock assembly comprising: a latch, the latch configured to move rotationally relative to the lock assembly; and a hand-operable member configured to move laterally relative to a fore-end of the lock assembly; wherein the hand-operable member is coupled to the latch such that lateral movement of the hand-operable member drives rotational movement of the latch. Methods of installing a lock assembly, comprising setting a hub of a lock assembly to one of a first unlocked position, a first locked position, a second unlocked position, a second locked position, or a deadlocked position, and installing a cylinder lock for engagement with the hub.

A lock for a pet transporter is provided. The lock includes a gear drive set, at least one pair of lock rods, and a chassis. Each lock rod includes an inner end including a rack portion having a structure for engaging with a transmission gear of the gear drive set, each transmission gear having a structure for engaging with a main gear of the gear drive set such that rotation of the main gear drives rotation of each engaged transmission gear. In use, rotation of the main gear in a first direction synchronously drives the first pair of lock rods into the corresponding lock holes to engage the lock, and rotation of the main gear in an opposite direction synchronously drives the first pair of lock rods out of the corresponding lock holes to disengage the lock.

A motor vehicle drive assembly, which is equipped with an electric motor and an output element, which is driven by the electric motor indirectly or directly. Furthermore, a spring associated with the output element is realized, which spring is designed to bidirectionally return the output element. According to the invention, the spring is designed as a spiral spring which is designed to be windable and unwindable proceeding both from the inner spring let and from the outer leg.

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 door bolt structure of an electronic device includes a door frame, a door panel, and a resilient metallic wire. The door panel is movably disposed at the door frame and provides a hermetic seal to the door frame. The two ends of the resilient metallic wire are connected to the door panel. The resilient metallic wire bends to form hook portions which protrude from the edge of the door panel. When the door panel provides a hermetic seal for the door frame, the hook portions are engaged with an inner edge of the door frame. When pulled, the resilient metallic wire drives the hook portions to separate from the door frame, thereby allowing the door panel to move relative to the door frame.

A lock for securing to a movable body (1) and for cooperating with a strike plate (12) on a stationary body (11), which lock is movable away from the strike plate (12) for opening the movable body (11), which lock is movable into juxtaposition with the strike plate (12) for closing the movable body (11) and which lock comprises a casing (3) which includes a rotatable trigger (8) which is positioned in the casing (3) and a locking member (7) which is also positioned in the casing (3) and wherein; the rotatable trigger (8) projects from the casing (3); the rotatable trigger (8) rotates about an axis of rotation positioned on a front working plane of the casing (3) such that the rotatable trigger (8) rotates into the casing (3) and out of the casing (3) with the rotatable trigger (8) being spring biased to rotate out of the casing (3); the locking member (7) is movable between a projected position in which the locking member (7) projects from the casing (3) and a retracted position in which the locking member (7) is retracted into the casing (3); the locking member (7) is configured to move into the projected position when the rotatable trigger (8) rotates into the casing (3); the locking member (7) is configured to move into the retracted position when the rotatable trigger (8) rotates out of the casing (3); the locking member (7) moves into a locked position when the lock is brought into juxtaposition with the strike plate (12) such that the rotatable trigger (8) rotates into the casing (3) as it comes into juxtaposition with the strike plate (12), whereby the locking member (7) projects from the casing (3) such that the locking member (7) moves into a recess in the strike plate to lock the movable body (1) and: • when the lock is moved out of juxtaposition with the strike plate (12) the rotatable trigger (8) rotates out of the casing (3) and the locking member (7) moves into the retracted position.

A motor vehicle lock, in particular a motor vehicle door lock, comprising a locking mechanism consisting essentially of a rotary latch and a pawl, further comprising an actuation lever chain for the locking mechanism, and comprising a locking element, at least one securing element, and exactly one spring element that cooperates with both the locking element and the securing element. The actuation lever chain can be controlled via the locking element to be put at least into the functional states “unlocked” and “locked” and can be additionally controlled via the securing element to be put into the functional states “non-secured” and “secured.” According to the invention, the spring element additionally cooperates with the actuation lever chain.

A safety device for a motor vehicle, having a lock holder, a pawl and a rotary latch, wherein the rotary latch has a load arm, a catch arm, an opening direction of rotation, a closing direction of rotation, a pre-latching position and a main latching position, wherein the pawl is latched in on the catch arm in the pre-latching position and is latched in on the load arm in the main latching position.

A safety device for a motor vehicle, which has a striker, a pawl, an ejection spring ejecting the striker, and a rotary latch, wherein the rotary latch has an opening direction of rotation, a closing direction of rotation an open position, and a main locking position, wherein the ejection spring has a leg and the leg lies directly against the striker in the main locking position of the rotary latch and the leg lies directly against the rotary latch in at least one intermediate position of the rotary latch, in which the rotary latch is between the main locking position and the open position.
