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.

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 integrated latch apparatus for a securing and releasing computer equipment from a chassis includes a support bracket, a rotating shaft, a sliding plate having a latching extension, and a handle having a rotating end. The handle is secured at the rotating end to the support bracket about the rotating shaft. The rotating end of the handle includes nudging extensions. A torsion spring is disposed on the rotating shaft such that the torsion spring biases the support bracket against the handle such that the handle is in an open position when the torsion spring is extended towards an equilibrium state and in a closed position when the torsion spring is biased toward a fully compressed state. The nudging extensions engage and laterally move a sliding plate when the handle is rotated between the open position and the closed position.

Certain exemplary embodiments can provide a system, which can comprise a securement. The securement comprises a rising member and defining at least a first slot. The system can comprise a locking member, the locking member defining an aperture. Wherein, when operatively coupled to the securement, a padlock coupled to the locking member via the aperture prevents removal of the locking member from the securement.

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 flush glass apparatus includes an operation glass comprising a glass portion and a frame and configured to open and close an opening of a fixed glass by sliding in a lateral direction, and a locking device configured to lock and unlock the operation glass, wherein the locking device comprises an operation handle installed on the frame, an upper locking lever installed on an upper side of the frame, a first lower locking lever installed on a lower side of the frame, a second lower locking lever installed on the lower side of the frame, an upper operation member installed on the upper side of the frame and connected to the operation handle, and a lower operation member installed on the lower side of the frame and connected to the operation handle.

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 door fitting having a handle that can be locked on one side, including at least one rosette for contact with a door leaf and a shaft element for forming an operative connection to the locking mechanism of a lock unit fitted into the door leaf, and an adapter element being fitted in a neck section of the handle and being held on the shaft element. In order to create a simple embodiment of a handle that can be locked on one side, according to the invention, it is provided that a locking device is held in or on the neck section of the handle, which is brought by means of a manual actuation into a blocking position, in which the handle can be rotation ally blocked against the rosette by means of the locking device.

A handle set includes a main body that has a handle and a faceplate positioned around the handle, the faceplate having a toggle aperture. The handle set includes a locking mechanism that includes a locking piece that has a locking notch. The locking mechanism includes a toggle positioned within a toggle housing, the toggle being movable relative to the toggle housing. The toggle includes a toggle tail configured to be received into the locking notch. The toggle includes a toggle head removably attached to the toggle tail, the toggle head being at least one of a privacy attachment button and a passage attachment button. At least a portion of the privacy attachment button extends from the toggle aperture and beyond the faceplate. The passage attachment button interfaces with the toggle housing to prevent relative movement between the passage attachment button and the toggle housing.
