A door locking mechanism is contained within a cartridge for use with a tubular style door lock. The cartridge activates and deactivates the door lock with a manual depression of a push button. Depressing the push button causes a cam to rotate thus converting the axial motion of the push button into a rotary motion thereby activating the door lock. Once locked, both the interior and exterior door knobs may not be rotated. In order to unlock the door, the push button is depressed a second time thereby rotating the cam in an opposing direction and deactivating the door lock.

Disclosed are a door lock and a door system, the door lock includes: a lock body, the lock body including a lock case, a spring bolt assembly and a shifting sleeve, the spring bolt assembly being slidably arranged in the lock case, so as to be able to extend and retract relative to the lock case, the shifting sleeve being rotatably arranged in the lock case, and the shifting sleeve being in transmission connection with the spring bolt assembly; and a first handle assembly, the first handle assembly being provided with a locking head and a motor, the locking head being rotatabversly provided with a shifting head, the shifting head being in transmission connection with the shifting sleeve, and an output shaft of the motor being in transmission connection with the shifting head, so as to be able to drive the shifting head to rotate.

A lock assembly is provided for a window having a first sash and a second sash. The lock assembly comprises an elongate strip configured to be coupled to the first sash. The elongate strip has a plurality of recesses defined along a length of the elongate strip. The lock assembly also includes a lock member configured to be coupled to the second sash and operable to move along the length of the elongate strip. The lock member includes a biasing member and a coupler biased in a direction of the elongate strip by the biasing member. The coupler is configured to enter each of the plurality of recesses to selectively lock the lock member to the elongate strip.

A button assembly for a door lock may include a button and a shank. The button may be toollessly couplable to the shank to allow force transmission between the button and the shank. The button may transfer linear force and torque along a longitudinal axis of the button to the shank to allow a state of an associated lock body to be changed.

A handle assembly for a window or door leaf having first and second opposing sides, the handle assembly having a forward end and a rearward end, the handle assembly comprising: a first handle grip, configured for mounting to a first side of the leaf, the first handle grip being moveable rotatably and axially relative to a first handle axis, and a second handle grip configured for mounting to the second side of the leaf, the second handle grip being movable at least rotatably relative to a second handle axis, each handle grip having a closed position, wherein the handle grip is in a first angular position and an open position, wherein the handle grip is in a second angular position, the handle assembly having a rest mode and a locked mode.

A latch assembly for mounting in an opening of a door and for releasably latching the door to a door frame. The latch assembly includes a housing that is mountable to the opening of the door. A lever is rotatably coupled to the housing between a deployed position and a retracted position. A lock plug is rotatably mounted within the housing, the lock plug having one end for receiving either a tool or key, and an opposite end having an engagement surface. A latching member is movably coupled to the housing, and is engaged with both the rotatable lock plug and the lever in the retracted position of the lever. A torsion spring biases the lock plug back to a starting position after the lock plug is rotated from the starting position using the tool or the key.

A push button lock an outer case and a button assembly movable relative to the outer case, the button assembly including a driver having a shoulder and a ramped surface. The push button lock also includes a tail movable relative to the outer case, and a spring retainer coupled to the tail. The shoulder is configured to engage and push the tail axially along a longitudinal axis when the button assembly is in an unlocked and depressed state, and a portion of the spring retainer is configured to be engaged and moved radially outwardly by the ramped surface when the button assembly is in a locked and depressed state.

A lock, including an outer subassembly, an inner subassembly, a safety mechanism, and a clutch. The clutch includes a square transmission tube and a sub-clutch. The safety mechanism includes a brake rod and a drive device. The inner subassembly includes an inner baffle plate, an inner baffle plate cover, a cylindrical tube, a transmission frame, and an inner doorknob. The inner baffle plate is inserted in the inner baffle plate cover. The cylindrical tube fits rotations of the inner baffle plate and the inner baffle plate cover. The transmission frame is disposed at one end of the cylindrical tube, and the inner doorknob is disposed at the other end of the cylindrical tube. The drive device includes a transmission member, a drive member, a first spring, a second spring, and a positioning slot. The positioning slot is disposed on the cylindrical tube.

There is provided a locking assembly mountable to a dispenser having a base part and a cover movable relative to each other between a closed configuration and an open configuration. The locking assembly is configured to lock the base part and the cover in the closed configuration when mounted to the dispenser and comprises an unlocking component mountable to one of the base part and the cover and having an unlocking body translatable to configure the locking assembly into an unlocked configuration; and a pushbutton at least partially contained in the unlocking body. The locking assembly is selectively configurable into a key-opening configuration wherein the pushbutton is prevented from translation and in a pushbutton-opening configuration wherein pressure on the pushbutton engages the unlocking body into translation to configure the locking assembly into the unlocked configuration.

The present invention relates to a self-locking pushbutton for unlocking of a lock for a vehicle door, hood, covering or hatch, in particular of an agricultural vehicle, e.g. of a tractor, or of a construction machine.
