Provided is a magnetic hinge device including a rotor having an elongated body with a rotor surface at least one permanent rotor magnet coupled to the rotor surface. A stator including an inner surface that defines a cavity to receive the rotor, the rotor is positioned within the stator along a common axis of rotation. The inner surface of the stator is generally radially continuous having a first edge portion and a second edge portion such that the first edge portion is attached to the second edge portion at an offset. The stator having at least one permanent stator magnet coupled to the inner surface. The rotor includes a radial position that is configured to rotate to a neutral position within the stator. The neutral position along the common axis of rotation is in approximate alignment with the offset.

A vehicle sliding door device includes at least one sliding door which can be moved in a movement direction or a pivoting and sliding door which can be pivoted in a pivoting direction and which can be moved in a movement direction relative to a door frame that has a door opening, and a locking device for locking the at least one sliding door at least in the closed position that includes an emergency unlocking device, by which the at least one sliding door which is locked in the closed position can be unlocked in the event of an emergency. An emergency opening device is provided for at least partly opening the at least one sliding door or the pivoting and sliding door in the event of an emergency in an emergency unlocking state.

A foot operated door opener comprises a front panel, a rear panel and an anti-slippery structure formed on the front panel. The front panel and the rear panel are connected and pivotally rotated through a hollow connecting tube of the front panel and two fixing tubes of the real panel. The present invention provides user's foot enough tension or fiction to easily flip or rotate the front panel from the rear panel in a folded or unfolded condition and push or pull the door along with the foot. The door will be hence opened simply by user's foot without their hands touching it. This could benefit the user with both hands holding and carrying stuffs and also could prevent germs or bacterial infection by not touching the door.

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.

A shaft-mounted overhead door operator is disclosed having a motor, a torque transfer component such as a gear train, and a clutch that is axially movable to engage or disengage the clutch. While the door operator has power, the clutch is engaged to ensure door operator can raise, lower, and stop the overhead door as directed from a remote control. The clutch can be released in the event of a loss of power or by direction from the remote control in which case the clutch releases the shaft of the overhead door. The shaft-mounted overhead door is small, having a width no greater than three times the diameter of the shaft to which it is mounted.

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 multi-body device includes a first machine body, a second machine body, a rotating member, a first magnetic member, a second magnetic member, and a stopper. The second machine body is pivoted to a pivot side of the first machine body. The rotating member is pivoted to the pivot side of the first machine body and located beside the second machine body. The first magnetic member is disposed at the second machine body. The second magnetic member is disposed at a portion of the rotating member corresponding to the first magnetic member. Two corresponding ends of the first magnetic member and the second magnetic member are magnetically repulsive to each other. The stopper is driven by the second machine body and disposed at the pivot side of the first machine body, so as to stretch into or retreat from a rotation path of the rotating member.

A playpen door, including a door frame; a door body movably mounted on the door frame; and a detection assembly mounted on the door frame and the door body and configured to detect open or closed state of the door body. The door body is hinged to the door frame. A locking assembly is arranged between the door body and the door frame. The locking assembly may be opened by a switch. The detection assembly is mounted away from a position where the door body is hinged to the door frame. When the door body rotates relative to the door frame, the detection assembly may be triggered, at which time the door body may be sensed to be open. When the door body returns to the closed position again after opening, the detection assembly may be triggered, at which time the door body may be sensed to be closed.

Examples herein relate to a hinge. In some examples, a hinge can include a first bracket connected to a shaft, a second bracket connected to the first bracket, a member connected to the shaft and magnetically attracted to a magnet at a first position, where the member translates relative to the magnet to a second position as the shaft rotates about an axis of the shaft, and the magnet to generate a magnetic attraction force between the member and the magnet, where the magnetic attraction force is higher at the second position than the first position.

An illumination system is provided for an access door may include an elongated illumination housing configured to be coupled to at least one of an upstanding jamb and a corresponding jamb casing extending along the one side of the access door, an elongated light transmissive cover coupled to the illumination housing, an elongated light pipe received within the illumination housing, an illumination source housing operatively coupled to one end of the light pipe, an illumination source disposed within the illumination source housing and configured to produce and transmit visible light into the light pipe so as to be visible through the light transmissive cover, a source of electrical power, and a control unit configured to selectively apply electrical power from the source of electrical power to the illumination source to produce the visible light.
