The invention relates to a fitting (1) for actuating a mechanism in a door or window, which has a handle (10) that is rotatably supported in or on a stop element (20) about an axis of rotation (D), wherein the stop element (20) can be fastened to the door or window, a drive pin (40) for actuating the mechanism in the door or window, a coupling element (50) for coupling the handle (10) to the drive pin (40), and a blocking device (70), which blocks the actuation of the drive pin (40) about the axis of rotation (D) when in the blocking position (A), wherein the blocking device (70) can be moved to a releasing position (B) through an axial actuation of the handle from a first position to a second position along the axis of rotation (D). In order to ensure increased security against unauthorized actuation of the fitting or the mechanism connected to the fitting in the window or door, and to obtain a fitting that is easy to manipulate and inexpensive to produce, the handle (10) is decoupled from the drive pin (40) in the first position (I), wherein the blocking device (70) is then in the blocking position (A), and the coupling element (50) couples the handle (10) and the drive pin (40) in the second position, and keeps the blocking device (70) in the releasing position (B). When the second position is reached, the handle is coupled to the drive pin, and unlocks it for the actuation of the mechanism.

The present disclosure is directed to a lock assembly that can be converted between a clutching and non-clutching orientation by rotating an outer housing 180 degrees relative to an outside drive assembly. The outer housing includes a notch and an elongate arcuate slot formed in the inner surface of the outer housing adjacent a through aperture and across from one another. A lock control lug is moveably coupled with the outside drive assembly and is selectively engageable with the notch or the arcuate slot of the outer housing. An outer lever is placed in a non-clutching configuration when the lock control lug is engaged with the notch and in a clutching configuration when the lock control lug is engaged with the arcuate slot.

A status indicating handle assembly generally includes a handle, an activation carrier mounted in the handle, and a status indicator mounted in the handle and engaged with the activation carrier. The handle includes a shank extending along a longitudinal axis and a grip portion extending laterally from the shank. The activation carrier is mounted in the shank, and has an unlocking position and a locking position. The status indicator has a first state in which a first indicium is displayed and a second state in which the first indicium is not displayed. The activation carrier transitions the status indicator between the first state and the second state as the activation carrier moves between the locking position and the unlocking position.

An actuating device (10) for actuating a lock device (12), the actuating device (10) comprising an actuating element (14) rotatably arrangeable with respect to a stationary structure (22) for rotation about an actuation axis (28); an electric generator (16) In fixed with respect to the actuating element (14) for common rotation with the actuating element (14); a drive member (18) connected to the actuating element (14) and arranged to drive the electric generator (16), the drive member (18) being arrangeable to be driven by engaging the stationary structure (22) and by manually rotating the actuating element (14); and an electromechanical coupling device (20) fixed with respect to the actuating element (14) for common rotation with the actuating element (14), and arranged to be electrically powered by the electric generator (16), the coupling device (20) being configured to adopt a decoupling state and a coupling state. A lock device (12) is also provided.

A keycam assembly including a rotatable member, a stem, a locking member coupled to the stem for joint longitudinal movement therewith, and a cam driver. The rotatable member includes an aperture. A proximal end portion of the stem is rotatably seated in the rotatable member and defines a cam track. The locking member extends between the aperture and the cam track. The cam track includes a first passage including a locking pocket, a second passage including an unlocking pocket, a first ramped passage including a locking ramp extending from the second passage to the locking pocket, and a second ramped passage including an unlocking ramp extending from the first passage to the unlocking pocket. Relative rotation of the rotatable member and the stem causes the cam driver to travel along the track to thereby cause movement of the locking member between a locking position and an unlocking position.

A lock includes a latch assembly, a first locking mechanism, a second locking mechanism, a linkage mechanism, a clutch mechanism, and a rebounding mechanism. The lock utilizes a first clutch member and a second clutch member of the clutch mechanism to coordinate with a leaning portion of an inner linkage member of the linkage mechanism to achieve that when the turned inner linkage member will outward push the first clutch member and the second clutch member away from each other to make the second clutch member rapidly and accurately be engaged with an outer linkage member of the linkage mechanism so as to make the outer linkage member to drive the latch assembly to unlock. The arrangement provided by the present invention that has the first clutch member and the second clutch member coordinate with the leaning portion of the inner linkage member simplifies the entire structure of the lock.

An exemplary product line system includes a common platform and a plurality of component families, each of which includes a plurality of interchangeable component species configured for use with the common platform. The common platform includes an inside drive assembly and a chassis assembly including a chassis and an outside drive assembly. A lockset assembled from the system includes the common platform and a plurality of modular components. Each of the modular components corresponds to a respective one of the component families, and is provided as a selected species of the corresponding component family. The lockset has a function defined by the set of component species installed to the lockset. The function of the lockset can be changed by altering the set of component species installed to the lockset without disassembling the chassis assembly.

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.
