Abstract: The present invention discloses a magnetic type floor hinge installed on the bottom surface of a door for reducing the opening and shutting speed of the door, the magnetic type floor hinge according to the present invention comprises an installing bracket divided into a magnetic operating part and a hinge operating part having one end on which a guide rail is installed; a moving plate installed to move linearly on the guide rail; a compressing spring installed between the moving plate and the installing bracket in the direction of movement of the moving plate; a main shaft cam rotatably installed on an upper portion of the moving plate, the main shaft cam being combined with a hinge shaft of the door and rotated along with the hinge shaft; a roller installed on one end of the moving plate, the roller being contacted with a cam-shaped surface of the main shaft cam; a disk rotatably installed at one end of the magnetic operating part of the installing bracket; a yoke installed on the magnetic operating part of the installing bracket; the yoke having permanent magnets attached thereto so as to generate repulsive force toward the upper and lower surfaces of the disk; and a gear-box in which a plurality of gears are contained installed between a rotating shaft of the main shaft cam and a rotating shaft of the disk so as to convert rotating movement of low speed of the main shaft cam to rotating movement of high speed of the disk. Therefore, according to the present invention, a magnetic type damper is applied to the floor hinge to generate damping force in a non-contacted type so that frictional force can be minimized, and the opening and shutting speed of the door can be maintained constantly in spite of change of temperature.
