A magnetically-triggered lock mechanism for interengaging two relatively movable components. The lock mechanism includes a bolt mounted within a first component composed of a first material and displaceable between retracted and extended positions to interengage with a second component when the first and second components are in a predetermined position relative to each other and the bolt is extended, and a magnetically-releasable latch mechanism positioned to latch the bolt in a retracted position, the latch mechanism including a first magnet and mounted for movement between a biased latch engaging position and a latch releasing position. A support collar composed of a second material having higher strength than that of the first material is disposed around the bolt between an inner casing and outer casing of the first component and is spaced from the bolt to allow for sliding movement of the bolt through the support collar as the bolt moves between the extended and retracted positions. The support collar absorbs and distributes to the inner and/or outer casing a load generated from the bolt as the bolt moves to the extended position through the support collar. A second magnet is positioned to displace the latch mechanism to the latch releasing position when the first component is in the predetermined position relative to the second component.

A corral gate latch release device facilitates quick release of a corral gate latch without a user having to dismount from a horse. The device includes a gate door and a latch coupled to and extending from the gate door. A base post is positioned adjacent to the gate door when the gate door is in a closed position. A latch lock is positioned on the base post to engage the latch when the gate door is in the closed position. A linkage is coupled to the base post and is operationally coupled to the latch lock to disengage the latch lock from the latch. A grip arm is operationally coupled to the linkage to be grasped to move the linkage for disengaging the latch lock from the latch.

In one example, an electronic device housing may include a first cover, a second cover, and a latch assembly to detachably connect the first cover and the second cover. The latch assembly may include a first bracket to fixedly engage with the first cover, a latch to slide back and forth along the first bracket between a lock position to hold the second cover and an unlock position to release the second cover, an elastic member disposed between the latch and the first bracket to generate a force to the latch to hold the second cover, and a cable connected to the latch. The cable may generate a pulling force to the latch to release the second cover when an external force is applied to the cable.

A hood-integrated vehicle body in which a hood, a bumper, and a fender are integrally formed into a single component so as to reduce the weight thereof is disclosed. The hood-integrated vehicle body includes a front vehicle body part, which is constructed such that a hood is integrally and rotatably connected to a front portion of the front vehicle body part and is openable at a rear side thereof, a lifting unit mounted to the front part of the vehicle so as to rotate the hood, and a locking unit, which is mounted to the front part of the vehicle so as to selectively engage the hood with the front part of the vehicle such that the engagement of the hood is released so as to allow the hood to be opened by means of the lifting unit upon manipulation for opening the hood.

A vehicle lock which eliminates the need for lubrication and which includes a bracket, a first base attached to the bracket, a second base attached to the bracket, aligned first and second apertures in the first and second bases for slidably receiving a. locking pin, a replaceable first locking pin wear protector lockably insertable in and selectively removable from the first base to prevent contact between the locking pin and the inner edge of the first base which defines the first aperture, and a replaceable second locking pin wear protector lockably insertable in and selectively removable from the second base to prevent contact between the locking pin and the inner edge of the second base which defines the second aperture.

Disclosed is a sliding window emergency opening system, comprising: an emergency opening device (2) and a general opening control device (3); wherein a first rotary shaft (202) in the emergency opening device is rotatably mounted on a first base (201); a first pulling cable (206) is wound around the first rotary shaft (202), and one end thereof is connected with a movable sash of the sliding window (1); a first ratchet (203) is fixedly connected with the first rotary shaft (202); a first elastic component is compressed to make a first pawl (204) abut against the first ratchet (203); a second rotary shaft (302) in the general opening control device (3) is rotatably mounted on a second base (301); one end of a general control pulling cable (303) is connected with the second rotary shaft (302), and the other end is connected with the first pawl (204); when the second rotary shaft (302) rotates, the general control pulling cable (303) is wound up to make the first pawl (204) detached from the first ratchet (203); under the action of the gravity of the movable sash in the sliding window, the first pulling cable (206) drives the first rotary shaft (202) to rotate so as to open the movable sash. In practical application, the general opening control device (3) may be provided at a location far from the emergency opening device (2), and the emergency opening device may be remotely controlled to open the movable sash.

A center slide assembly for a multi-point exit device. Upper and lower spool assemblies may be displaced from first positions to second positions along an inner region of a center slide. The displacement of the spool assemblies may displace upper and lower pull cables so as to retract latch mechanisms from extended positions to retracted positions. A first latching pin may be displaced, along with the displacement of the upper spool assembly, along an abutment surface of a tilting link so as to pivotally displace the tilting link from an unlocked position to a locked position. Displacement of the lower spool assembly may displace a second latching pin to a position wherein the second latching pin may be received and retained within a jog of the tilting link when the tilting link is in the locked position, which may thereby retain the associated latch mechanism in the retracted position.

The present invention provides a resistant lock for locking doors, having a locking mechanism that enable locking the door in any direction without any modification or adjustment thereof, and that provide improved security.

A magnetic self-latching device for a gate has a main body with handles on either side for operation or has an arrangement to be remotely actuated. A latching body has a high strength magnet usually provided at the bottom of a cavity which defines a latching shoulder. The latching body is adapted to be fixed to a gate post. The main body, with its housing, can be mounted on the gate frame and incorporates a latch pin which, in the door-closed position, is displaced by magnetic attraction to an extended latching position and against the biasing of a return spring. The gate cannot be opened until actuation of the mechanism occurs, for example by rotating a handle to retract the pin against the magnetic force; the gate can then be swung open. When the handle is released, the biasing spring retains the latch pin in a retracted position.
