Disclosed is a safety magnetic hinge for preventing a door from being suddenly closed by wind, by, when the hinge opens, fixing the hinge so as not to close at a predetermined angle through a magnet installed in the hinge.

A door system to provide a check function and door closing assistance in a vehicle is provided. The door system comprises a door hinge, a clip assembly attached to the door hinge and a door closing assist device disposed adjacent to the door hinge. The door hinge includes a body leaf fixed to a body of the vehicle, and a door leaf attached to a door of the vehicle and configured to be movable relative to the body leaf and the door leaf includes an engagement member. The clip assembly includes a check member having a distal end and a base end and the check member includes at least a first check portion adjacent to the distal end and a second check portion adjacent to the base end.

A damping mechanism is provided, including a damper housing, a damping assembly provided within the damper housing, and a damper cover assembly fitted to at least a portion of the damper housing. The damper cover assembly includes a damper cover and at least one connection member attached thereto. A recess is provided on a rearward side of the damper cover, and at least one receptacle is provided, defining an opening on a bottom surface of the damper cover and being adapted to receive and retain therein at least a portion of the at least one connection member of the damper cover assembly. The recess of the damper cover and the connection member of the damper cover assembly are cooperatively adapted to provide a mechanical connection between the damping mechanism and a hinge cup of a hinge assembly in a removable manner.

Provided is a swing door operator (110) for moving a door leaf (120) between a first position and a second position. The swing door operator (110) is arranged to operate in a powered and a powerless mode and comprises a permanent magnet DC motor (310). The motor (310) is arranged to move the door leaf (120) at least from the second position to the first position in the powered mode. The swing door operator (110) further comprises a mechanical drive unit (320), arranged to move the door leaf from the first position to the second position in the powerless mode. In the powerless mode, at least one resistive device is electrically connected in parallel with the motor (310) and arranged to limit a current generated by the motor (310) in response to the movement of the door leaf (120) from the first position to the second position by means of the mechanical drive unit (320). A method for controlling the swing door operator is also provided.

A system can include a housing that defines a first plane; a base that defines a second plane; and an adjustable hinge assembly that rotatably couples the base and the housing about an axis, where the hinge assembly includes permanent magnets that generate a first magnetic field and a second magnetic field orientable with respect to each other via rotation of the housing with respect to the base, where the first magnetic field and the second magnetic field include an aligned orientation, generate a clockwise restoring torque responsive to rotation of the housing in a first rotational direction from the aligned orientation, and generate a counterclockwise restoring torque responsive to rotation of the housing in a second, opposite rotational direction from the aligned orientation, and where the aligned orientation is adjustable to correspond to a selected angle between the first plane and the second plane.

A damping or return device for sliding door leaves, particularly for furniture, which is constituted by a steel pin that slideably and axially interacts within a magnet constituted by a diametrically differently-polarized collar.

A damping or return device for sliding door leaves, particularly for furniture, or for drawers, which is constituted by a pin the shank of which is constituted by a diametrically differently-polarized magnet that slideably and axially interacts with a steel plate or a complementarily-shaped collar, which is made of steel and polygonal

A damping or return device for sliding door leaves or drawers, particularly for furniture, is provided. The device has a first trolley, which is associated with a door leaf and is slideable with respect to an item of furniture, by a diametrically differently-polarized magnet, which is associated with the first trolley or with the item of furniture, and by at least one steel plate, which is associated with the item of furniture or with the first trolley. The first trolley interacts selectively with at least one elastically compressible element which abuts, in opening and in closing, with an abutment element which is associated with and protrudes from the item of furniture.

A computing device is movable into an airplane mode. A spine on a hinge connects a display to a keyboard. The back surface of the keyboard includes keyboard magnetic material and the spine include spine magnetic material. The spine magnetic material is magnetically attracted to the keyboard. In the airplane mode, the spine is magnetically connected to the keyboard such that the display is secured relative to the keyboard.

Disclosed is a hinge including: a first hinge component including: a first external surface for securing to a first structure; and a first magnetic element; and a second hinge component, pivotally coupled to the first hinge component, including: a second external surface for securing to a second structure; and a second magnetic element. A magnetic force between the first and second magnetic elements bias the first and second hinge components toward a retained position.
