A plastic arrangement that includes a first plastic component, a second plastic component, and a plastic lock mechanism for fastening the second plastic component to the first plastic component. The plastic lock mechanism includes a first lock unit and a second lock unit. The first lock unit includes a U-shaped cantilever member, a catch element and a catch element retention part. The second lock unit includes a protruding member and a protruding member retention part. The plastic lock mechanism provides a locked position wherein the catch element retention part restricts movement of the catch element for preventing the second plastic component from separating from the first plastic component, and the protruding member retention part restricts movement of the protruding member for hindering the moving of the first lock unit to a released position.

A securing device is provided. The securing device includes a body, a cover, a lock core, and a fastener. The cover is pivotally connected to the body. The cover is capable of rotating to a closed position or an open position with respect to the body. The lock core is disposed in the body or on the cover. When the lock core is in a locked state, at least a portion of the fastener is capable of inserting into the body from a side of the body, and the lock core restricts the fastener from leaving the body.

An electromechanical lock includes an electromechanical locking mechanism and a control circuit, wherein an associated counter-piece is locked by way of the locking mechanism. The locking mechanism has a latch, an entrainer that is rotatable about an axis of rotation for driving the latch, and an electric motor for driving the entrainer, wherein the latch is moveable between a locking position and an unlocking position, wherein the latch is preloaded in the direction of the locking position. The entrainer is rotatable into a release position, a standby position, and a blocking position and the latch can is driven to perform a movement into the unlocking position by rotating the entrainer into the release position. In the standby position, the latch is released to be urged back against the preload. In the blocking position, the entrainer blocks the latch against a movement in the direction of the unlocking position.

In general, one aspect of the subject matter described in this specification is embodied in a latch. The latch includes a ball joint. The ball joint includes a stem and a first ball positioned at a proximal end of the stem. The latch includes a casing that is configured to surround a portion of the stem and the first ball and secures the ball joint within an enclosure. The latch further includes a cap plate. The cap plate has a recess or cup that receives the first ball of the ball joint and allows the first ball to swivel within the recess or cup.

A safety switch includes a movably mounted locking bolt configured to lock an actuator in a defined locking position relative to the safety switch. The safety switch includes a movably mounted locking bulkhead movable between a first position and a second position. The locking bulkhead is configured to fix the movably mounted locking bolt in the second position via a positive fit.

A locking device for locking a first component to a second component, the device having: a catch element for fastening to the first or second component; a latching unit for fastening to the second or first component; the latching unit comprising a release element; and the release element can be moved between a rest position, which arranges the first latching body in the first latching recess of the catch element and in the receiving opening of the release element, and a release position, which releases the engagement between the first latching body and the first latching recess of the catch element.

An antitheft device attachable to an article, formed by two parts, one part comprises a means for remote interaction with a terminal detecting passage of the device, a hinge to allow movement between a protection position, and a release position, one of the parts having, at the end opposite to the movable hinge, a needle able to move in a direction perpendicular to the mid-plane of the device, the other part comprising a housing for receiving the needle, the housing comprising lock configured to allow the release of the needle with an opener, wherein the first part has three retractable cages enabling the needle to move between a retracted position where the tip of the needle does not project beyond the internal surface of the first part, and a deployed position in which the needle is engaged in the complementary housing when the device is in the closed position.

The invention discloses several types of fastener, fastening systems, fastener assemblies and related areas.

In particular, the invention relates to a releasable fastening system (50) which has a pin (152) with a locking cavity (163). The pin is intended for insertion in an aperture (154). A locking means (158, 160) engages the locking cavity (163) of the pin (152) when the pin (152) is received in the aperture (154). The system (150) also includes unlocking means (162) which includes material adapted to contract when activated. When a material contracts, engagement means (158) included in the locking means (158, 160), disengage the locking cavity (154).

A locking module for selectively coupling a first component and a second component of a lockable device includes a locking element including a plurality of locking fingers movable between an open position and a closed position. The plurality of locking fingers being biased to said open position. A biasing mechanism is coupled to said locking element and a compression force applied by said biasing mechanism to said plurality of locking fingers controls movement of said plurality of locking fingers between said open position and said closed position. An actuator associated with said biasing mechanism is operable to control said compression force to selectively lock said locking element.

A profile rail (1) is provided for forming a locker system (2) having a plurality of lockers (21, . . . , 26). The profile rail (1) is formed to integrate a locking mechanism (31) of one of the lockers (21) within the profile rail (1). The profile rail (1) comprises a lamella device (11) to cover the integrated locking mechanism (31; 32). The lamella device (11) is arranged to be displaceable in the direction of the longitudinal extension (L) of the profile rail (1). The lamella device (11) can be retained at a retaining site (12) of the profile rail (1) against longitudinal displacement.
