A latch assembly comprising: a latch operable to adopt a latched condition and an unlatched condition; a magnet imparting a magnetic field; a sensor adapted to sense the magnetic field; the latch, magnet and sensor being configured such that a change in the condition of the latch effects a variance in the magnetic field sensed by the sensor to distinguish between the latched condition and the unlatched condition, wherein the latch includes a latch member that is moveable relative to both the sensor and the magnet when the latch changes from the unlatched condition to the latched condition and the proximity of the latch member to the magnet changes the strength of the magnetic field sensed by the sensor.

A magnetic latch for fastening a closure member to a support comprising a latch assembly and a keeper assembly. The latch assembly comprises: a frame (70); a latch bolt (14) moveable between a latching position and a retracted position along a horizontal direction; and a latch bolt operating mechanism configured to move the latch bolt from its latching position to its retracted position. The latch bolt moved into its latching position by magnetic attraction. The latch bolt operating mechanism comprises an operation lever (91) and a support lever (92) both of which have a first part pivotally connected to the frame and a second part connected to the latch bolt. The latch bolt is suspended by the operation lever and the support lever and is swingable between its latching position and its retracted position.

The present invention relates to an automatic lock mechanism for foldable systems, where such lock mechanism is used with any kind of foldable system, such as a stretcher that consists of a plurality of panels, where the intelligent lock of each foldable panel is made by a measurement system that determines when the folds are in the desired position, this is, parallel to one another or one after the other, and an electronic lock system that triggers a magnetic lock when panels reach the desired position to create a stiff element from the panels comprising the foldable system.

The present invention is directed to a latch mechanism for latching a door or window panel to a frame. The latch mechanism includes: a pair of first members, a first of the pair of first members being located in an upper region of either the door or window panel or the frame, and a second of the pair of first members being located in a lower region of either the door or window panel or the frame and a pair of second members, a first of the pair of second members being located in an upper region of the other of the door or window panel or the frame to the first of the pair of first members and a second of the pair of second members being located in a lower region of the other of the door or window panel or the frame to the second of the pair first members the second members being movable between an unlatched position and a latched position wherein the second members are brought into abutment with, or close proximity to, the respective first members, wherein the first members are adapted to move from the unlatched position to the latched position under a magnetic attraction to the respective second members when the door or window panel is brought into a closed condition and wherein the second members are coupled to a controller via one or more linkage members, wherein actuation of the controller results in moving the second members from the latched position to the unlatched position.

A strike assembly for a mechanical or magnetic lock including an elongated body configured as a cup having a receiving cavity that is opened frontally to engage the bolt or the latch of the lock, and holes for fixing screws with a support element. The strike assembly further includes a separate face plate, having an opening that conforms to the cavity of the cup body for the bolt or the latch of the lock. In the assembled condition, the face plate is superimposed on the cup body, hiding the holes of the fixing screws; the face plate is further provided with rear legs configured with fitting portions for fitting to the cup body.

A screwless strike device for latch- or bolt-locks includes a box body of elongated shape, having a front cavity configured for engaging the latch or bolt of a lock, and a face plate that conforms to the box body. The box body is provided with one or more elastically yieldable locking arms, configured for locking the box body in a housing seat of a door frame or other support member. The face plate is provided with one or more rear pushing members, configured to be press-fitted between the locking arms and respective contrasting surfaces of the box body, to open the locking arms and push the locking arms against an inner surface of the housing seat of the box body.

Disclosed, in some embodiments, is a latch assembly mountable to a structure for securing a moveable barrier in a closed position. The latch assembly comprising a latching unit with a displaceable latch pin, and a retractable actuator mounted in a housing of the latching unit. The retractable actuator being moveable along a latch axis to move the latch pin towards a retracted position to enable the moveable barrier to be moveable from the closed position. The retractable actuator including an elongate body extending between opposing ends, and a knob being formed separate to the elongate body and mounted thereon via a mounting arrangement. Also disclosed, in some embodiments, is a receiver unit having a magnet for attracting the latch pin the latch pin towards a displaced position. The receiver unit including a receiver body and a carrier, the receiver body including an interior surface defining a cavity for receiving the carrier therein. The carrier being configured for retaining the magnet. The carrier includes at least one retention portion

A base member for a tablet computing device including a fastener to removably couple a tablet computing device to the base. A receptacle can receive a security lock to secure the base, wherein the security lock is to prevent the fastener from releasing the tablet computing device in a first mode and allows the releasing of the tablet computing device in a second mode.

A door bolt structure of an electronic device includes a door frame, a door panel, and a resilient metallic wire. The door panel is movably disposed at the door frame and provides a hermetic seal to the door frame. The two ends of the resilient metallic wire are connected to the door panel. The resilient metallic wire bends to form hook portions which protrude from the edge of the door panel. When the door panel provides a hermetic seal for the door frame, the hook portions are engaged with an inner edge of the door frame. When pulled, the resilient metallic wire drives the hook portions to separate from the door frame, thereby allowing the door panel to move relative to the door frame.

An elevator call box with internal, concealable latching mechanism comprises an internally disposed, cylindrical magnetic pin with a relatively low pull force that is slidably displaceable by an larger, external magnetic force supplied by a service technician. When the access door is closed, magnetic pin penetrates an orifice in a locking tab to lock the call box. The pin magnet is normally attracted to an adjacent, magnetically attractive clip snap-fitted to a latching block. The latch is externally disengaged via a stronger portable magnet carried by service personnel. The larger magnetic pull force of the portable magnet slidably displaces the smaller magnetic latch pin, freeing the locking tab to permit pivotal opening of the access door. Once the stronger magnet is moved away, the smaller magnetic pin, which is attracted magnetically to the clip, will return to it's rest position penetrating the locking tab and locking the control.
