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.

A latch structure according to an embodiment includes a body, a locking body, a latch head, a plunger, and a latch stopper. The body is disposed inside a door. The locking body moves in response to an external operation. The latch head protrudes from the body to maintain the door in a closed position, and rotates when the locking body is spaced apart at least a predetermined distance. The plunger retracts into the body to prevent the latch head from rotating while the door is being closed. The latch stopper prevents the protruding latch head from retracting into the body when the plunger is maintained within the body.

An adapter configured to convert a rotary motion of a drive shaft for a door lock actuating mechanism into a translational motion for actuating a door latch. The adapter includes a housing with a compartment and a first lever inside the compartment, enables retrofitting of US-style doors with a European style door handle by providing a first bearing that rotatably supports the first lever relative to the housing, wherein the first bearing has a first axis of rotation, wherein the housing has a channel, the channel has a first opening facing the lever and a second opening facing away from the lever, wherein a first channel axis extends through the centers of the first and second openings. The first lever has a hole, configured for receiving the drive shaft, wherein the longitudinal axis of the drive shaft correlates with the first axis of rotation. The first lever further has first coupling means for providing a torque proof coupling with the drive shaft. A second bearing pivotably attaches the lever to a connecting rod, where-in the second bearing has a second axis of rotation, wherein the connecting rod has a first connecting element at the end of the connecting rod opposite to the lever. The first connecting element is moveably supported inside the first channel, wherein the channel walls limit a translation of the first connecting element in directions perpendicular to the first channel axis and enable a translation along the first channel axis.

Handle device for operating doors, windows and the like, comprising a first element (3), which is rotatable about an axis of rotation, a second element (8, 108, 208, 308), and a coupling device which is designed to selectively allow and prevent relative rotation about the axis of rotation between the first and the second element. The coupling device comprises; a first coupling member (15, 115, 215, 315, 515, 615) being connected to the first element; a second coupling member (8, 150, 208, 350) being connected to constituting the second element and at least one engaging member (19, 119, 219, 319, 519) which is displaceable between an engagement position in which it simultaneously engages the first and the second coupling members to thereby prevent relative rotation between the first and second element and a release position in which it is disengaged from at least one of the first and second coupling members to thereby allow relative rotation between the first and second element. A drive member (21, 121, 221, 321, 421, 521, 621) is arranged axially displaceable, concentrically with said axis of rotation, by means of an electrical motor (6, 106, 206, 306, 406, 506) having a rotational output shaft (36, 136, 236, 336, 436, 536, 636). The engaging member and drive member comprise interacting contact surfaces arranged, during axial displacement of the drive member, to displace the engagement member from the release position to the engagement position. The drive member exhibits an interior recess (27, 127, 227, 327, 427, 527). A portion (36, 136, 236, 336, 436a, 536, 636) of the output shaft extends axially through the recess. A helical coil spring (38, 138, 238, 338, 538, 638) is arranged in the recess, concentrically about the output shaft, limitedly axially displaceable relative to the drive member and the output shaft and prevented from free rotation relative to the drive member or the output shaft. The output shaft or the drive member is provided with a radially extending spring engagement member (37, 137, 237, 337, 537, 637) which is arranged to engage the helical coil spring for axial displacement of the drive member relative to the output shaft upon rotation of the output shaft.

A sliding bolt latch as disclosed herein is convenient to use and more reliable than counterpart door locking mechanisms of the prior art. A user may open and close a door with only one hand, but the present mechanism requires both a rotational movement and a translational movement of elements against a biasing force. Such requirement makes opening doors much more difficult for livestock confined to spaces by the closed doors. Also, the biasing of elements into the locking state makes embodiments of the invention less likely to unlock inadvertently in the presence of ambient vibrations.

A latch assembly includes a frame and a pawl including a surface for receiving a striker and being movably coupled to the frame between an open and a closed position. A trigger is mounted to the frame and is movable between a locked position and an unlocked position, wherein, in the locked position of the trigger, the trigger is positioned to retain the pawl in the closed position. A striker bar is movably coupled to the trigger and is positioned to be contacted by the striker, wherein the striker bar is configured to move in the course of moving the striker into the pawl. A device for sensing a position of the striker bar, wherein the position of the striker bar is indicative of the position of the striker and the position of the trigger.

A latching handleset assembly includes a handle, a trigger, and a latch driver. The handle has a handle portion and a top mounting portion that extends from an escutcheon. The top mounting portion has a top surface and a bottom that is at least partially obscured by the handle portion. The trigger includes an exterior end located along the bottom of the top mounting portion and an interior end extending into the escutcheon. The trigger is pivotable about a pivot point positioned within the escutcheon. The latch driver is movable between a neutral position and a latch actuating position in response to actuation of the trigger.

Spring-projected latch bolt assemblies each having a retractable latch bolt component are used to upgrade commercially available lock operating mechanisms so that closures carrying the upgraded lock operating mechanisms can lock automatically when the closures reach their fully closed positions. To permit unobstructed closing of each closure, a normally extended component of each associated spring-projected latch bolt assembly retracts during a final segment of the closing of an associated closure, and snaps back to its fully extended position as the associated closure comes to rest in its fully closed position.
