A locking assembly for a dispenser may include a locking component and a barrel. The locking component is movable between (i) a first position configured to lock a cover of the dispenser, and (ii) a second position configured to unlock the cover. The barrel is rotatable between (i) a first barrel position configured to resist movement of the locking component, and (ii) a second barrel position configured to permit movement of the locking component. The barrel defines a barrel opening configured to receive a key or a push button. A dispenser including a dispenser plate and a cover may further include the locking assembly. The dispenser defines an interior closable with the cover. The cover is movably coupled to the dispenser plate. The locking assembly releasably secures the cover to the dispenser plate.

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.

The Safe Key Park Brake (SKPB) knob is a lever with an integrated centered key locking system to prevent unauthorized operation of air brake vehicles. The SKPB is also designed as an anti-theft device. Air brake levers are always active and accessible whether the engine is on or off. In an emergency, such as assisting a passenger, with the SKPB in place the driver can safely assist without running the risk of the vehicle being exposed to danger. The SKPB is locked by a key that turns clockwise into the key shaft. This prevents the push to release function of the brake. To regain full operation, the key is turned counterclockwise. This allows full operation of the push to release function. The SKPB has a quick and easy-to-apply key locking feature. An alternative solution to securing a park brake is creating closure around the vehicle operator's area.

A clutch driving module is disposed in a lock which is able to drive the clutch driving module selectively to control an exterior handle assembly whether be able to drive a latch assembly in lock or unlock or not. And the clutch driving module is able to respectively make an interior handle assembly and the exterior handle assembly controlling the lock in lock or unlock independently.

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 herein is an apparatus for opening and closing an entrance. The apparatus includes: first and second door handles which are configured to be pushed or pulled; a moving unit which is coupled to the first and second door handles; a rotating unit which is rotatably coupled on a rotating shaft and locked to the moving unit so that when the moving unit horizontally moves, the rotating unit rotates around the rotating shaft; an actuating member which is locked to the rotating unit and moved in a direction perpendicular to a direction in which the moving unit moves; a latch unit which is fixed to the actuating member so that the latch unit is ejected from or retracted into the door by the movement of the actuating member; and a restoring spring which is wrapped around the rotating shaft and fixed to the door lock housing and the rotating unit.

Disclosed herein is an apparatus for opening and closing a front entrance. The apparatus includes: a door lock housing which has an opening in which a latch bolt is disposed; first and second door handles which are provided on the door and configured to be pushed or pulled; a movable member which is disposed in the door lock housing and horizontally moved by pushing or pulling either the first door handle or the second door handle, with a lift guide block provided on the movable member; a rotating unit which includes a roller and a bent part; a latch bolt coupling unit which is locked to the bent part of the rotating unit and coupled to the latch bolt; and a restoring spring which is configured such that the rotating unit is returned to its original state.

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.
