A handle for a compartment of a low, medium or high voltage switchgear includes: a body part; a hand grasping part; and a lock. The handle is movable from a closed position to an open position. When the handle is in the closed position, the handle is not useable to open a door of a compartment of the switchgear. When the handle is in the open position, the handle is useable to open the door of the compartment of the switchgear. In the open position, the hand grasping part is positioned so as to be graspable by a human user. In the closed position, a transition of an active element in the compartment of the switchgear from a quiescent state to an active or potentially active state activates the lock. Activation of the lock stops the handle from moving from the closed position to the open position.

A latch and method for a double sash tilt window includes a locking mechanism and a rack having proximal and distal ends. The proximal end of the rack is connected to the locking mechanism while the distal end of the rack is affixed to a slide bolt. The latch also includes a cam and a gear, the cam positioned on the gear and the gear enmeshed with the rack so that rotating the gear operates the slide bolt which prevents the window from tilting.

An appliance body of a refrigeration appliance can be closed off in its upper part by at least one door and receives a drawer in its lower part. The drawer can be locked in the closed position by a latch, which engages into a fitting part that supports the door.

A fenestration assembly includes a fenestration frame and at least one panel movable between open and closed positions. A locking mechanism is coupled with the at least one panel and includes at least one latch and at least one latch fastener. The panel includes a secure configuration with the panel in the closed position and the latch coupled with the latch fastener. In the unsecure configuration one or more of the panel is in the open position or the latch is decoupled from the latch fastener. A status monitoring assembly monitors the secure and unsecure configurations and includes a sensor operator coupled with the latch, and a sensor coupled with one of the fenestration frame or the panel. In the secure configuration, the status monitoring assembly detects the sensor operator with the sensor if the panel is in the closed position and the latch is coupled with the latch fastener.

A door interlock device for a power transformer room in a vacuum circuit breaker includes a cam disposed on a shaft of a ground switch, a supporter disposed on a side plate of a power transformer room, a shaft disposed at the supporter to be slidable and having one end contacting the cam to be upward and downward movable, a spring disposed within the supporter to provide an upward elastic force to the shaft, and an interlock plate disposed at one side of the power transformer room door and configured to be in contact with the shaft.

A cooling appliance including a locking mechanism configured to fix the door to the main body at a different position from the latch mechanism, in a state where the door fixed to the main body by the latch mechanism closes the cooking chamber, wherein the locking mechanism provided in the door may include a shaft moved to a fixing position, at which the shaft is coupled to the hinge member, or a releasing position, at which the shaft is released from the coupling state, by a repeated pressing manipulation.

A transmission mechanism of handle lock set used for driving a latch to perform extension/retraction action includes a driving plate and a transmission plate. The driving plate includes a supporting portion having a transmission surface with an arc surface and a blocking surface with a flat surface. The driving plate is rotated to make the supporting portion swinging between a first position and a second position. The transmission plate further includes a protrusion having a contact surface. The transmission surface contacts the contact surface and pushes the protrusion to prevent the driving plate from being unavailable due to transmission dead spot occurrence when the supporting portion locates at the first position. The blocking surface contacts the contact surface of the protrusion to prevent the driving plate from over rotation for avoiding unavailable return when the supporting portion of the driving plate locates at the second position.

A glove box for a vehicle according to the present invention includes: a push rod housing which is fixed to a glove box door; a push rod which is slidably disposed in the push rod housing in order to lock or unlock the glove box door; and a guide rod which is coupled to the push rod, and moved along an outer surface of the push rod housing when the push rod slides, such that when a user presses the knob, the knob is operated without rattling.

A modular latch bar is formed from a first segment that is configured to be connected to a locker handle and one or more extension segments which are attached to the first segment. One of the segments has an elongated body having a front surface, a back surface, a first end and a second end; and a T-shaped locking tab extending from the first end. Another segment has an elongated body having a front surface, a back surface, a first end and a second end. This segment has a T-shaped recess on the back surface. The T-shaped recess is sized and configured to receive the T-shaped locking tab and create a friction fit between the T-shaped locking tab and segment having the T-shaped recess. A post may be provided in the recess that fits into a hole in the T-shaped locking tab to provide a snap fit connection.
