A sliding door handle and strike assembly includes a locking member for engaging the strike to prevent the door from opening. The locking member is biased to an unlocked position, until it is moved into a locking position, in which magnetic co-operation acts to hold the locking member in the locking position.

A magnetic safety gate latch assembly and method of operation. The assembly includes: a pool latch tube, a user-actuated lid coupled to the top end of the pool latch tube; a rotatable shaft within the pool latch tube, an upper end of the shaft rigidly coupled to the lid, and a lower end of the shaft including a shaped base. The assembly further includes a magnet housing that at least partially encloses the shaped base and includes an aperture to cooperatively engage with the shaped base. The assembly further includes a bottom cover coupled to the lower end of the pool latch tube and enclosing the magnet housing, the bottom cover including an aperture facing a latch pin housing, the aperture positioned to expose a magnet. The assembly further includes a ferromagnetic latch pin and housing, and a magnetic latch pin guide slidably enclosing the latch pin.

The disclosure relates to a magnetic-actuation latch device. The magnetic-actuation latch device includes a housing, a latch element, a sliding plate, an elastic component, a rotating element and a limitation element. A lateral opening of the housing spatially corresponds a first magnetic block mounted on a fixed component. When a second magnetic block of the latch element is aligned to the first magnetic block, an actuation force is generated to drive the latch element to pass through the lateral opening and engage with the fixed component. The elastic component is connected between the sliding plate and the housing. When the rotating element is rotated by an external force, the sliding plate is driven to misalign the second magnetic block from the first magnetic block, and the latch element does not pass through the lateral opening. The limitation element is pivotally connected to the housing for blocking the rotating element.

In a door latch for a hinged or pivoting door having a latch fixture mounted in or on the door that supports a slideable bolt that is magnetically attracted to a fixed strike so as to effect latching action by extension of the bolt, a safety catch mechanism which, while engaged, prevents the bolt from extending, the safety catch mechanism having a catch member that operatively acts between the moveable bolt and the latch fixture, and an operating mechanism to operate the catch member responsive to magnetic forces from the strike. First and second actuators are disposed to opposite sides of the door, each of the first and second actuators being coupled to the latching mechanism to effect withdrawal of the latch bolt from its extended position to its retracted position upon operation by a user. A privacy lock mechanism is operable from one side of the door only and can be used to prevent the actuator on the other side of the door from operating the latch.

A magnetic lock has a magnetically operable latch having a magnetically repellable or attractable latch element. A magnetic operating device spaced from the latch has a first magnet with a respective magnetic direction and a second magnet with a respective magnetic direction. The first magnet is rotatable between a latched position with its magnetic direction generally parallel to and pointing oppositely to the magnetic direction of the second magnet for contracting a magnetic field formed by the first and second magnets, and a release position generally parallel to and with its magnetic direction pointing the same as the second magnet for extending the magnetic field to and repelling or attracting the latch element.

A magnetic door lock control system for use with an egress handle system and a door is provided. The magnetic door lock control system employs magnets that communicate with one another across the door jamb thereby eliminating the need for a hard wired electrical connection between the egress handle system (e.g., a mechanical switch bar) configured with a door and a door locking mechanism mounted above the door in the header of the entranceway. In this way, the need for an electrical wire loop between the egress handles and the door locking mechanism is eliminated.

A magnetic self-latching device for a gate has a main body with handles on either side for operation or has an arrangement to be remotely actuated. A latching body has a high strength magnet usually provided at the bottom of a cavity which defines a latching shoulder. The latching body is adapted to be fixed to a gate post. The main body, with its housing, can be mounted on the gate frame and incorporates a latch pin which, in the door-closed position, is displaced by magnetic attraction to an extended latching position and against the biasing of a return spring. The gate cannot be opened until actuation of the mechanism occurs, for example by rotating a handle to retract the pin against the magnetic force; the gate can then be swung open. When the handle is released, the biasing spring retains the latch pin in a retracted position.

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.

A door-operating assembly has first and second subassemblies each having a housing, a magnet, a sleeve carrying the sleeve and rotatable in the respective housing about an axis, an actuator for rotating the first sleeve about the respective axis, and a rotation limiter restricting rotation of the respective sleeve and magnet. The magnets in a first position repel and push the respective sleeves axially away from each other such that the first rotation limiter is effective in a first direction on the first sleeve and the second rotation limiter is effective in a second rotation direction on the second sleeve. Conversely, the magnets in a second position attract and pull the sleeves axially toward each other such that the first rotation limiter is effective against the first rotation direction on the first sleeve and the second rotation limiter is effective against the second rotation direction on the second sleeve.

A mounting assembly comprising: a bracket; a mounting part; and a height adjustment mechanism to vary the position of the mounting part with respect to the bracket in the vertical direction. The height adjustment mechanism comprises: a set of interlocking elements; an arm connected to the bracket and having a protrusion that is moveable in a depth direction with respect to the bracket between a retracted position and a locking position in which the free end interlocks with an interlocking element; and at least one set screw extending along the vertical direction. Rotating the set screw moves the set screw in the vertical direction and pushes the protrusion from its retracted position to its locking position.
