A safety switch comprises a switching device having a casing housing electric and/or electronic control means adapted to be connected with one or more circuits, an operating device adapted to be anchored to a movable part of the access to interact with the switching means when the access is opened/closed for the opening/closure of the circuits, means for detecting the opening of the access associated with the switching device and with the operating device for sending a stop command of the machine or plant upon the detection or request for the opening of the access, driving means for sending activation/deactivation and/or signalling controls and that comprise a touch monitor provided with one or more virtual controls and at least one microprocessor suitable for associating the virtual controls with a control and/or signalling function.

A safety switch (2) with a latching unit (12), by means of which an associated actuator (3) is held in a latched position. The latching unit (12) has an arrangement of latching jaws (14). Each latching jaw (14) is spring-mounted by means of a spring unit (15). The latching jaws (14) are concentrically arranged and each face one another with a first free end and delimit an insertion opening (A). The latching jaws (14) are held in latched position by the spring forces generated by the spring units (15). The latching jaws (14) can be displaced against the spring forces of the spring unit (15), which serves to enlarge the insertion opening (A).

The present invention provides a buckle lock includes a lock member and a buckle base which are able to be inserted and locked to each other. The buckle base includes a lock portion and a release button, and the lock portion includes at least one locking mechanism. It is characterized in that when the locking mechanism is in a locked state, the lock member can still be inserted into the buckle base and the lock connection is completed immediately after completing the locking action.

A quick connection and/or fastening system suited to mutually connect and disconnect a first and a second element is disclosed, the system including a first and a second component that are suited to be rigidly fixed to the first and second elements, respectively, the first component and the second component being also suited to be mutually connected and disconnected, the second component being suited to house an end portion of the first component in such a way as to allow its translation inside the second component, the second component comprising also counteracting elements suited to counteract the translation of the end portion of the first component towards the outside of the second component.

The invention discloses a locking device and a refrigerator, wherein the locking device comprises a first lock block and a second lock block; the first lock block comprises a base and a tongue; the second lock block comprises an accommodating cavity, a clamping block, a return spring and a pushing block; the pushing block pushes the clamping block to slide in the sliding groove; and the tongue enters the tongue channel to be engaged with the clamping block so that the two lock blocks are engaged with each other. The locking device has the function of automatically adjusting the height difference between different cabinet doors and cabinet bodies, and is therefore more flexibly suitable for locking various cabinets or refrigerators.

Provided is a push-to-open latch for an oven appliance and other household appliances. The push-to-open latch includes an integrated locking device for locking an appliance door in place and initiate a downstream appliance function such as a self-cleaning function. The integrated locking device includes a rotating cam having a latching slot which engages a pawl. The rotating cam also includes a guiding ramp and a catch surface which may be used to engage a latching finger to lock the cam in place. In addition, the locking device may include a locking slide and a locking slide pin that is actuated by a solenoid to engage the cam. Once the appliance door is locked, one or more switches send a signal to the appliance controller to activate the downstream function.

A locking piece for a locking unit includes a housing having a housing opening. A locking arm, which engages through the housing opening, is mounted so as to be displaceable, in a direction at a right angle to its longitudinal direction, in the housing opening. A slide is guided displaceably in the housing in the displacement direction of the locking arm and is motion-coupled to the locking arm in the displacement direction. The housing and/or the slide are/is formed from magnetically attractable material. At least one magnet acts between the housing and slide and positionally fixes the locking arm in each possible displacement position within the housing opening.

A latching system for releasably securing a first structure relative to a second structure. The latching system includes a latch assembly coupled to the first structure and a keeper assembly coupled to the second structure. The latch assembly is selectively engageable with the keeper assembly to hold the first structure against movement relative to the second structure.

A rack security system includes a locking mechanism connected to a server. The locking mechanism is configured to lock onto the busbar of a rack. When the locking mechanism is locked to the busbar, the locking mechanism may prevent removal of the server from the rack. When the locking mechanism is unlocked, the server may be removable from the rack.

A safety door device according to an aspect includes: a full closing detector for detecting that a safety door has fully closed from an opened state; a locking mechanism for locking the safety door so that the safety door does not open; a measurement unit (acceleration sensor, control unit for measuring a travel acceleration, a travel speed, or a travel time when the safety door closes; and a control unit for controlling the locking mechanism to lock the safety door when the safety door is detected to be fully closed. If the travel acceleration or the travel speed is greater than a first threshold, or if the travel time is shorter than a second threshold, then the control unit does not cause the safety door to be locked.
