A handle-equipped lock. The lock comprises a latch bolt, a lock housing, and a release mechanism inside the lock housing. The handle includes handgrip, a spindle sleeve contiguous with the handgrip, and a polygonal shaped spindle, which has a part of its length inside the spindle sleeve and which is dimensioned to extend to an engagement with the lock's release mechanism. The shaped spindle, or a part thereof, is adapted to be manipulated inside the spindle sleeve between an unlocking position and a locking position. In the unlocking position, the shaped spindle extends to the lock's release mechanism and in the locking position it does not extend. The shaped spindle and the spindle sleeve are provided with locking means for securing the same relative to each other in said locking position, wherein manipulation of the shaped spindle is prevented. Alternatively, a continuous shaped spindle extends through the lock and the handle is capable of being manipulated relative to the shaped spindle between an unlocking position and a locking position.

A handle set including a chassis and a handle mounted on the chassis. The handle includes a shank having a load bearing section, a primary actuating section, and a secondary actuating section. The chassis includes a housing, a support spindle, a primary actuator, and a secondary actuator. The support spindle is longitudinally coupled with the load bearing section, and the primary actuator is rotationally coupled with the primary actuating section of the handle. The handle set has a first configuration in which the secondary actuating section is engaged with the secondary actuator, and a second configuration in which the secondary actuating section is disengaged from the secondary actuator.

The present disclosure provides a lock and a method and a system for controlling the lock. The lock may include an operation part, an action part, and a bolt. The action part may be configured to drive the bolt to move. The operation part and the action part may be connected to each other via a transmission connection. The transmission connection may be blockable.

An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electro-mechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state. The interchangeable electro-mechanical lock core may include a core keeper moveably coupled to a lock core body. The core keeper may be positionable in a retain position wherein the core keeper extends beyond an envelope of lock core body to hold the lock core body in an opening of the lock device and a remove position wherein the core keeper is retracted relative to retain position to permit removal.

An exemplary knob assembly includes a knob having a circumferential channel, and a deformable ring seated in the circumferential channel. The ring is normally rotatable relative to the knob such that rotation of the ring does not cause a corresponding rotation of the knob. When gripped with a sufficient gripping force, the ring frictionally engages and rotationally couples with the knob, thereby permitting transmission of torque between the ring and the knob. In certain embodiments, the knob assembly may include a detent mechanism operable to selectively couple the ring and the knob. In certain embodiments, the ring may include protrusions operable to engage pockets in the knob to provide for rotational coupling.

The invention relates to an improved locking device for the closure of doors on cabinets, of boxes or compartments, which offers high resistance to unauthorized attack and, in particular, can take up high torques. For this purpose, use is made of a coupling arrangement having a manually or electronically movable actuating member, a driver (40), which interacts with the actuating member, and a blocking member (50). The blocking member (50) has the form of a cylinder, the cylinder axis of which runs parallel to the rotor axis (19). The blocking member (50) in its blocking position engages in a depression (17) on the outer side of the rotor (10) or in a depression (22) on the inner side of the wall (21) of the stator (20) and is held in this blocking position by spring force.

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 clutch engagement assembly for a door lock device includes a first shaft having at an end thereof an insertion end portion in which a channel is formed; a second drive shaft having a hollow engagement end portion into which the insertion end portion of the first shaft is inserted; a driving member which provides a driving force; and a pin member that is installed in a state of being elastically supported in the engagement end portion of the second shaft and is movable by the driving member so as to extending through (be inserted in) at least a part of the first shaft and at least a part of the second shaft, thereby causing a clutch engagement or a disengagement between a first shaft and a second shaft. The clutch engagement assembly may provide a relatively small size structure of the door lock device and a firm engagement force.

A locking device comprises a latch, a spindle and a rotary assembly. The latch is fixed to an object to be locked for engaging with a bore of a strike; the latch has a bolt which locks the object. One end of the spindle is detachably connected to the latch to drive the bolt to move towards or away from the bore. The rotary assembly is disposed at the other end of the spindle, which comprises a cylinder body and a rotary body, the cylinder body is rotated by the rotary body as it rotates, wherein one end of the rotary assembly is provided with a spindle driving means engaged with the other end of the spindle to drive the spindle to rotate. The rotary assembly drives the spindle to rotate via the spindle driving means, and the spindle drives the bolt to move approaching the bore to realize locking.

A computing device is secured in an enclosure by a locking mechanism. The locking mechanism includes a jaw, a transmission lever, and an arm. The jaw is configured to abut a portion of the enclosure for holding the computing device. The transmission lever includes an arm pivot at one end and an actuating pivot at the opposite end. The arm is configured to rotate open and closed about the arm pivot and be selectively decoupled from the transmission lever. When the arm is coupled to the transmission lever, opening the arm causes the transmission lever to rotate open about the actuating pivot. Rotating open the transmission lever about the actuating pivot releases the jaw from the portion of the enclosure, and allows the computing device to be removed from the enclosure.
