Abstract:
A magnetic gate latch has a multiplicity of permanent magnets arranged on a pair of disks with half of the magnets in mutual attraction and half of the magnets in mutual repulsion. These magnetic forces are used to brake and close a gate or door. One of the disks is made axially movable with respect to the other so as to assume mutual repulsion in one position and mutual attraction in a second position. The movable disk is attached to a gate or door closing member and the other disk is attached to the closing structure post or jamb. Magnetic forces in the repulsion position are used in the invention to reverse the movable disk from a mutual repulsion position to a mutual attraction position.

Abstract:
A preassembled drive unit for an adjustable functional element in a motor vehicle has a drive motor (1) and a braking device (2). A drive connection (3) is provided for producing the driving force or driving torque of the drive motor (1) and a brake connection (4) is provided for producing the braking force or braking torque of the braking means (2).
Abstract:
A hinge structure is provided. The hinge structure uses a magnetic force and includes a shaft, provided at one side of a cover and rotatably supported by a body. At least one permanent magnet having a magnetic field perpendicular to the longitudinal direction of the shaft is fixed to the shaft. A shaft operation portion is provided in the cover for rotating the shaft by about 180 degrees and rotating between a first position and a second position by a user's operation. At least one electromagnet is arranged at a position corresponding to the permanent magnet of the body, thereby aiding the opening and closing of the cover and absorbing any impact using a magnetic force between the permanent magnet and the electromagnet.
Abstract:
A magnetic type floor hinge installed on a door, comprising an installing bracket, a moving plate, a compressing spring, a longitudinal hole in the moving plate, a main shaft cam in contact with the longitudinal hole. The main shaft cam is rotatably connected to a hinge shaft of the door and rotates with the hinge shaft. The magnetic type floor hinge further comprises at least one roller attached to the moving plate, a disk rotatably attached to the installing bracket, a yoke attached to the installing bracket and arranged around a magnetic operating part, and a gear-box comprising a plurality of gears that are connected between a rotating shaft of the main shaft cam and a rotating shaft of the disk. During operation of this magnetic type floor hinge, the rotating movement of the door hinge is converted to a rotating movement of the disk.
