Abstract: A latch is usable for latching and automatically unlatching a lid operative to close a bin of a waste container. The latch includes a release weight that is moveable responsive to gravity from a first position to a second position to cause the latch to disengage from a release mechanism when the latch is rotated to one or more angular positions in a dump angular orientation. The latch and release mechanism are held in latched engagement when release slide bolts and latch slide bolts are engaged in extended positions. Movement of the release weight causes the latch slide bolts to move to retracted positions to enable disengagement of the release slide bolts and latch slide bolts. A release knob is operative responsive to manual movement in two different directions to enable the latch and release slide bolts to disengage.

Abstract: An actuator-controlled strike comprising a housing disposable within a doorframe and including a chamber for receiving a spring latch and a dead latch of a mortise-type lockset. A keeper is pivotably mounted within the chamber to restrain the spring latch. A pivotable spring latch lifter is positively driven by the keeper, and a pivotable dead latch release platform is supported by the keeper when the spring latch is locked within the strike. The keeper is released by the actuator and then may be rotated which causes rotation of the dead latch release platform, allowing the dead latch to enter the chamber. The keeper positively drives the spring latch lifter to lift the spring latch onto the external ramp of the strike. In an alternate embodiment, an internal ramp feature may be used instead of the spring latch lifter to positively lift the spring latch out of the chamber.

Abstract: A vehicular door device in which an inner handle is connected to a latch mechanism with a wire so as to be capable of being linked, and in which a latch release restriction device that disables and restricts a link between the inner handle and the latch is provided in an operation transmission path ranging from the inner handle to the latch with the wire in between. A release motor that actuates the latch in an engagement releasing direction is provided, the release motor being linked to the latch without having the wire between itself and the latch. When a switch operation of the door opening switch is performed, restriction to the link performed by the latch release restriction device is cancelled and the release motor is actuated in the engagement releasing direction without waiting for the cancellation of the restriction to be completed.

Abstract: A lock with a locking mechanism includes a rotary catch and a pawl for engaging the rotary catch, and a releasing lever for opening or releasing the locking mechanism. The lock may include a blocking lever capable of blocking the pawl if the latter is located in its catching position. If the releasing lever is actuated, the pawl or the blocking lever is thereby moved out of its blocking position if the releasing lever is not excessively accelerated. If excessively large accelerations of the releasing lever occur, as can be caused by a crash, then an arresting device of the lock prevents the releasing lever from being able to move the pawl or the blocking lever out of its blocking or latching position, respectively. The lock is therefore incapable of opening if the releasing lever is accelerated in the event of a crash.

Abstract: A lock structure includes a case, a first latch, a second latch, a transmission member, a transmission module, a swaying plate and a driving plate, wherein the transmission module is rotated to drive the swaying plate and the transmission member to perform swing action for making the swaying plate driving the first latch being hidden into the case. In addition, the driving plate moves upwardly by swing action of the transmission member, and the driving plate drives the second latch in operation for making the second latch being hidden into the case.

Abstract: An electric latch retraction device for vertical rod door latches includes an automatic adjustment feature including a limit switch and a linear sensor, such as a Hall effect sensor, which detects vertical position. A microcontroller monitors the vertical position of a pivoting retraction lever driven at the pivot by a linear driver. The housing for the electric latch retraction device is preferably external to the door and one end of the retraction lever extends into the door to drive a vertical rod door latch mechanism while an opposed end contacts the limit switch to signal that continued driving of the linear driver will begin to drive the vertical rod door latch. The microcontroller determines from the vertical position of the retraction lever when the limit switch is actuated whether the electric latch retraction device is mounted too high or too low.

Abstract: A security seal includes a molded one piece body and a cover disc. The body has a cylindrical chamber for receiving the disc. A locking recess is formed in the body in communication with the chamber and defined in part by a locking shoulder. The cover is secured to the body in the chamber to enclose the locking recess. The disc is separated from the body when enclosing the chamber. A rotatable arm is attached to an extension member extending from the body via a hinge. The free end of the arm has an arrow shaped locking element attached that engages the recess locking shoulder when inserted into the recess. The locking element has a resilient tang member that is compressed by the locking shoulder and which tang member returns to its acquiescent state when fully inserted into the recess thereby locking the tang member in the recess.

Abstract: A low profile actuating window lock for casement windows having a handle actuate a lifter that slides vertically on a fork component in slidable communication with the window lock casing, the handle pivotable about the lifter and pivotable about a restrictor arm that pivots relative to the casing, allowing the handle to rotate fully from the locked position to the unlocked position with low clearance from the window frame. The pivot points of the handle, lifter, restrictor arm configuration allow for an over center linkage that prevents back driving the casement window lock.

Abstract: A low release effort eccentric double pawl vehicle latch includes a ratchet, primary pawl, auxiliary ratchet and secondary pawl in combination with a secure lock lever. The secure lock lever selectively inhibits movement of the secondary pawl to prevent premature or unintended opening of the latch. A drive mechanism sequences movement of the secure lock lever and secondary pawl to open the latch. Upon reset, the drive mechanism drives the auxiliary ratchet back to its closed state and in the process the auxiliary ratchet can engage and return the secondary pawl back to a closed state in the event of an insufficient bias force thereon.

Abstract: A deadbolt lock with an interior assembly having a status light indicator. The deadbolt assembly has a bolt movable between an extended position and a retracted position. An interior locking assembly includes a turnpiece configured to move the bolt between its extended position and retracted position, a light, and a detection circuit. The detection circuit is configured to detect when the bolt is in the extended position and actuate the light responsive to detecting that the bolt being in the extended position.

Abstract: A locking structure for securing an electronic device includes a body, a worm shaft, a guide rod, a fixing base and a linkage set. When a user wants to connect the electronic device to another device, the user could insert the electronic device into the locking structure which is set on the device. Then, the user pushes down the electronic device to drive the locking structure and the worm shaft of the locking structure would be rotated from a releasing direction to a securing direction. When the user wants to release the electronic device, the user could push it back to the original position. Then, the worm shaft would be rotated from the securing direction to the releasing direction so the user could release the electronic device from the locking structure. Consequently, it is easy to secure or release the electronic device to another device through the locking structure.

The proximal end of the rack is connected to the locking mechanism while the distal end of the rack is affixed to a slide bolt. The latch also includes a cam and a gear, the cam positioned on the gear and the gear enmeshed with the rack so that rotating the gear operates the slide bolt which prevents the window from tilting.
