A magnetic lock has a barrel and keyway, the barrel when rotated unlocking the lock. Locking element cavities each contain a moveable locking element such as a ball, movable in response to a magnetic field applied by a magnetic key. A locking bar is movable between a locked position and an unlocked position. The locking bar has coded projections which extend into the respective locking element cavities when the locking bar moves from the locked position to the unlocked position. A code plate is shaped in registration with the coded projections. When the locking bar is in the locked position the code plate and the coded projections form a substantially uninterrupted surface. The locking elements prevent movement of the locking bar from the locked position to the unlocked position except when magnetically moved to a coded position.

Lock assemblies having cylinders with interchangeable cores are provided. In one embodiment a lock assembly comprises a cylinder including a keyway and a core. Also, the lock assembly includes a first driver operatively connected to the cylinder. In particular, key cuts of the core are changeable without removing the cylinder from the driver.

A rotary locking device includes a thumbturn member, a latch member held to and turnable by the thumbturn member, and a limiting structure provided on the thumbturn member for movably connecting to or interfering with the thumbturn member. The rotary locking device can be mounted on a first object, and the thumbturn member can be turned for the latch member to turn to a position to lock a second object, so that the first and the second object are quickly and easily locked to each other. The limiting structure limits an angle by which the thumbturn member or the latch member can be turned. When the thumbturn member is turned reversely, the latch member is brought to unlock the second object, so that the first and the second object are quickly and easily separated from each other.

A cam lock according to the invention has a lock cylinder and a cam part connected to the lock cylinder. The cam part is turnable from a lock position to an open position when turning a key placed in the lock cylinder. The cam part comprises a spring and a flange that is arranged to receive external force towards the lock cylinder. The spring allows the movement of the cam part at the open position towards the lock cylinder as response to external force. The spring is further arranged to turn the cam part towards the lock position.

A vehicle includes a chassis. a body coupled to the chassis, and a seating unit. The body includes a partition and a floor. The partition separates an interior of the body into a cab area and a cargo area. The floor defines a first interface within the cab area and a second interface within the cargo area. The first interface and the second interface are discrete and not connected. The seating unit includes a frame assembly having a pair of legs that engage with the first interface and the second interface such that the seating unit is selectively repositionable between (a) a first position forward of the partition and within the cab area and (b) a second position rearward of the partition and within the cargo area.

A combination lock can be operated manually via the manipulation of rotatable dials and by way of a key, such as an electronic key. The lock includes one or more rotatable dials each having multiple indicia disposed thereon. Rotation of the rotatable dials to predetermined indicia places the lock in the unlocked position. The lock can further include an electronic port and an actuator. Upon receipt of a predetermined credential via the port, the actuator can place the lock in in the unlocked position. The lock further includes a knob that, when the lock is in the unlocked position, can be rotated between a first position in which the lock is in a latched position and a second position in which the lock is in an unlatched position. The combination lock may automatically scramble the positions of the dials upon opening for security purposes.

A lock can include attack-resistant and/or weather-resistant features. Attack-resistant features can include a sacrificial link between a locking mechanism and an external keyway covering an exterior face of the locking mechanism. The sacrificial link can break during a torque attack on the lock such that the full force of the torque attack is not applied to the locking mechanism. Weather-resistant features can include drain openings in one or more housing components external to the locking mechanism to facilitate drainage of liquid matter from the lock before the liquid matter reaches the locking mechanism.

An electronic device includes: a support defining a slot, a casing defining a receiving hole, and a locking assembly for detachably connecting the casing to the support. The locking assembly includes a connection member received in the receiving hole and a locking member connected to and rotatable together with the connection member. The locking member is rotatable to a position where the locking member engages the slot, thereby fixing the casing to the support.

A door lock extender and method of using the door lock extender in connection with a control panel box. The door lock extender includes an extender base having a lock slot for accepting a tang latch of a lock and an extender latch that is configured to engage a catch member of a control panel box. In use, the tang latch of the lock is inserted into the lock slot of the extender base. The extender latch engages the catch member on a housing of the control panel box locking a door to the housing while providing sufficient clearance for passage of a cable between the door and the housing.

A pressing type latch device includes a seat, a pivotal seat mounted in the seat, and a handle having a grasping portion pivotably connected to two eccentric locations of the pivotal seat, such that a greater operational height can be formed when the handle is lifted. When the latch device is in one of a plurality of retainable open positions or a retainable closed position, the grasping portion of the handle can be moved to a position to lift the pivotal seat, such that the grasping portion of the handle lies flush with the pivotal seat. On the other hand, when the grasping portion of the handle is lifted to move the pivotal seat downward, the handle and the pivotal seat can rotate freely. Since the latch device includes a closed position and a plurality of open positions, the latch device can be installed and used more easily.
