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.

A door lock assembly with interchangeable lock cylinders is described. The door lock assembly includes a handle. The handle includes a lock cylinder passage to receive a push to lock cylinder or a key to lock cylinder. A spring plate includes a bolt opening to position the lock cylinder. The spring plate further includes a side bolt opening. A side bolt is configured to selectively enter the side bolt opening of the spring plate to lock the lock cylinder and to selectively withdraw the side bolt from the side bolt opening of the spring plate to unlock the lock cylinder.

A locking system for a fuel compartment assembly of a work vehicle, the locking system having a housing at least partially defining a fuel access compartment, a door pivotally coupled to the housing and movable between an opened position, at which the door provides access to the fuel access compartment, and a closed position, at which the door blocks access to the fuel access compartment, and a locking assembly configured to lock the door at the closed position. The locking assembly includes a catch fixed to the housing and positioned within the fuel access compartment, and a latch arm pivotably coupled to the door at a pivot point defined between first and second ends of the latch arm, the pivot point defining a first pivot axis, where the latch arm is configured to be pivoted about the first pivot axis to be selectively engaged and disengaged with the catch.

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 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.
