A toggle latch device translates a first push and release of a button to a locking pin translation from retracted to extended from within a housing. A second push and release of the button reverses the locking pin translation from extended to retracted back within the housing. The latch button remains desirably flush with the housing after each push and release. The translation of the latch button and that of the locking pin is angularly displaced by 90 degrees allowing the toggle latch device to employ a unique lever system which includes a buckling spring combined with a reversing hat which forces the locking pin in each of extension and retraction.

The present invention discloses a motored locking mechanism, comprising a motor, two groups of transmission mechanisms that are arranged mirror symmetrically and two output components that are arranged mirror symmetrically, wherein the transmission mechanisms transfer power of the motor to the output components, wherein the motor is provided at an output end with a driving gear, wherein the driving gear is attached to an output shaft of the motor. The transmission mechanisms on two mirror sides are controlled by a common motor so the volume is smaller with a simpler structure. Regarding both sides of the lock, the transmission mechanism of one side is driven wherein the other side not. Thus, two unrelated systems are driven by a single motor.

A latch arrangement may comprise a latch bolt configured to rotate about a pivot, and a shear pin coupled to the latch bolt. A counterbore may receive the shear pin whereby lateral loads may be transferred between a door panel and a frame.

The present invention discloses a lock that does not distinguish between public and private spaces and relates to the field of locks, comprising two sub locking systems which have the same structure, wherein the two sub locking systems are arranged mirror symmetrically on two sides. It can be optionally installed on both spaces where privacy is needed and a change of the entire lock is not required, such that all designs of an indoor layout and different requirements for design logics regarding doors are adjusted to, that a locking on both sides in an electrically controlled manner is possible, that rotation of a cylinder on both sides is prevented, and that an unlaching movement on both sides in an electrically controlled manner is possible.

A door locking device, in particular an electromagnetic door locking device, for a door with a rotary catch for a closing bolt of the door, wherein in particular said rotary catch can be acted upon or is acted upon in particular by a torque, wherein the rotary catch has a closing bearing surface. The door locking device includes a pivoting body, in particular a pivoting locking body, and a lever body, wherein the pivoting body is connected to the lever body by a connecting body, wherein the connecting body is connected by a first joint to the pivoting body and by a second joint to the lever body, wherein in a closed position of the rotary catch the closing bearing surface of the rotary catch is in contact or is able to be brought into contact with the first joint between the pivoting body and the connecting body.

A vehicle opening and closing body operating device includes: a full-open lock opening lever connected to a full-open lock configured to maintain an opening and closing body in a fully opened state, and configured to output release operating force to the full-open lock; an input lever connected to the full-open lock opening lever and an operating handle, and configured to rotate the full-open lock opening lever so as to output the release operating force; a release lever connected to the input lever through a connecting member, and configured to rotate the full-open lock opening lever through the connecting member and the input lever; an emergency input lever to which rotation operating force is inputted; and a cancel mechanism configured to move the connecting member from a connection position where the input and release levers are connected to a disconnection position where the input and release levers are disconnected.

A bottom opening password lock comprises a lock case and a liner arranged in the lock case as well as a shackle connected with a top of the lock case, and a fork, a password assembly and a locking mechanism are installed and arranged on the liner; the password assembly comprises a pin shaft and a second spring, a clutch sleeve, a password wheel, a code adjusting lever and a washer sleeved on the pin shaft. One end of the second spring is abutted against an inner side of the washer, and the other end is abutted against the clutch sleeve away from the code adjusting lever. The bottom opening of the present invention adjusts a password through the code adjusting lever, the code adjusting lever is toggled manually, the code adjusting lever directly pushes the clutch sleeve to move and separate from the password wheel, and the pin shaft is motionless. The code adjusting lever is located at the bottom of a lock body, which is convenient to adjust, may not be lost, and is more convenient for users to use.

A latch arrangement may comprise a latch bolt configured to rotate about a pivot, and a shear pin coupled to the latch bolt. A counterbore may receive the shear pin whereby lateral loads may be transferred between a door panel and a frame.

A latch includes a base having a bore extending therethrough defining an axis, a plunger positioned within the bore and rotatable about the axis, a drive shaft positioned adjacent the base and engaged with the plunger such that rotation of the plunger about the axis causes corresponding rotation of the drive shaft about the axis, a bracket positioned adjacent the base and the drive shaft and engaged with the drive shaft such that rotation of the drive shaft about the axis causes movement of the bracket, and a closure element coupled to the bracket such that movement of the bracket causes the closure element to move between a position wherein the closure element allows a structure to move with respect to an adjacent structure and a position in which the closure element prevents the structure from moving with respect to the adjacent structure.

A lock assembly has an actuator that is moveable between first and second positions and a locking structure that is coupled to the actuator. The locking structure is positioned to engage a portion of a lock when the actuator is in the first position to prevent movement of the actuator to the second position. A latch assembly is preferably coupled to the actuator and includes a latch that is moveable between engaged and disengaged positions. Moving the actuator from the first position to the second position moves the latch to the engaged position, and moving the actuator from the first position to a third position moves the latch to a disengaged position.
