The electromagnetic holding magnet includes a yoke and a retaining plate interacting with the yoke as an anchor. At least one permanent magnet generates a magnetic retaining flux in the yoke that includes a first yoke leg and a second yoke leg as well as a middle pole. The middle pole is surrounded in sections by a magnetic coil. The first and second yoke legs are arranged symmetrically in relation to the middle pole and the magnetic coil.

In one aspect the flexible material is a magnetic vinyl. In another aspect, a decorative door handle comprising molded resin having at least one magnetic insert in the back surface. In another aspect, a decorative hinge element comprising molded resin having at least one magnetic insert in the back surface.

An intelligent door lock system is coupled to a door at a dwelling. A sensor is at the dwelling. The sensor is coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at the door. The lock device is coupled to the sensor and includes a bolt. An engine, an energy source and a memory are coupled together. A camera is coupled to or part of the intelligent door lock system. The camera is configured to define a safe zone in the dwelling in which an occupant, and a non dwelling occupant third person is allowed into the dwelling.

The present invention relates to a locking mechanism for a magnetic lock and including a locking body assembly. The locking mechanism includes a lock latch and a slide bar switch that move between an active and non-active positions. The lock latch cannot move freely in the active position, but can in the non-active position. The lock latch receives a magnet, and can move freely through magnetic force action. The locking body assembly includes a locking body and a locking plate. The locking body has a housings that form a cavity. When the locking mechanism and lock latch are fixed in the cavity, a hook portion of the lock latch can extend out of or retract into the cavity as the lock latch pivots, thereby engaging or disengaging with the locking plate, and either locking or unlocking the latch. The magnetic lock includes a key and the locking body assembly.

Disclosed is a two way swinging door opening gap control device for controlling the movements of companion animals that is detachably attached to the existing door and door frame with ease, without any structural change or damage, thereby being applied conveniently to various types of doors, and that controls an opening gap of the door to allow the companion animals to freely enter through the door, to prevent the door from being excessively opened by external wind or animals entering therethrough, and to limit the spaces the animals can enter according to animal sizes to thus provide individual living spaces for the animals. According to the present invention, the opening gap control device largely includes a gap control band 100, a locking pin module 200, and a locking holder module 300.

A lock mechanism includes a pedal, a vertical rod, a rod support, a hinge, a hinge support, a hinge lock, and magnets. When the pedal is pushed up the vertical rod, the hinge will lower into a cavity of the hinge lock and the lock mechanism will be in a “locked” mode. To “unlock” the lock mechanism, the user pushes the pedal down the vertical rod, then the hinge will raise out of the cavity of the hinge lock and now the lock mechanism will be in an “unlocked” mode. Then when the user wants to lock the lock mechanism while being inside a bathroom stall, the user will align a door with a wall/stand of the bathroom stall and then push the pedal up so the hinge will lower into the cavity of the hinge lock and the lock mechanism will be in a “locked” mode.

Actuator (10) comprising a base section (14,14a,14b); a permanent magnet (18,18a,18b); an electro permanent magnet (20, 20a, 20b); a coil (22, 22a, 22b) located around the electro permanent magnet (20, 20a, 20b); a power controller (24, 24a, 24b); and a movable member (28) comprising at least one magnetic target section (36), the movable member (28) being arranged to move to a first position (12) relative to the base section (14,14a,14b), when the electro permanent magnet (20, 20a, 20b) adopts a first polarity, and arranged to move to a second position (46) relative to the base section (14,14a,14b) due to a magnetic field generated by the permanent magnet (18,18a,18b) and the electro permanent magnet (20, 20a, 20b) in combination and acting on the magnetic target section (36), when the electro permanent magnet (20, 20a, 20b) adopts a second polarity. A lock device (50), a handle device (86) and a method are also provided.

An electronic keeper includes a housing defining a battery chamber and an actuator chamber. An actuator is at least partially disposed within the actuator chamber. The actuator includes a strike and a magnet, and is pivotable between a first position and a second position relative to the housing. The actuator is also biased towards the first position. The electronic keeper also includes a senor disposed within the battery chamber. When a locking element is in contact with the strike, the actuator pivots from the first position towards the second position so that the magnet moves relative to the sensor.

A lock mechanism for interengaging two relatively movable components includes a bolt mounted within a first component and interengageable with a second component when the first and second components are in a predetermined position relative to each other and the bolt is extended. A magnetically-releasable latch mechanism is positioned to latch the bolt in a retracted position and is mounted for movement between a biased latch engaging position and a latch releasing position in a non-common direction of movement of the bolt. A first magnet is disposed within a trigger being translatable along an axis parallel to a longitudinal axis of the bolt and a second magnet is positioned to displace the latch mechanism to the latch releasing position as the trigger is caused to translate vertically when the first component is in the predetermined position relative to the second component to permit displacement of the bolt to the extended position.

An intelligent door lock system coupled to a door at a dwelling. a door status device is at the dwelling. The door status device is coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at the door. The lock device is coupled to the door status device and includes a bolt. An engine, an energy source and a memory are coupled together. A camera is coupled to or part of the intelligent door lock system. The camera is configured to record in response to door lock status.
