戸体の移動速度調整装置及び建具
Document Type and Number:
Japanese Patent JP6670213
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a moving speed of a door body adjuster and fittings which can apply a damping force corresponding to a moving speed when necessary regardless of a position of the door body.SOLUTION: A moving speed of a door body adjuster and fittings comprise a rotary shaft 25 which rotates interlocked with a movement of a door body, a speed increasing machine 45 connected to the rotary shaft 25 for increasing a rotating speed of the rotary shaft 25 and outputting it from an output shaft 47, a generator 46 connected to the output shaft 47 of the speed increasing machine 45 for generating electricity using a rotation of the output shaft 47, a resistance unit 60 for imparting resistance corresponding to viscosity to a rotation of the rotary shaft 25 using a magnetic viscous fluid 64 the viscosity of which changes according to a magnetic field, a resistance coil 70 for applying a magnetic field to the magnetic viscous fluid using an electric current generated in the generator 46, a thyristor circuit 80 as a controlling circuit which supplies an electric current to the resistance unit 60 when an output voltage of the generator 46 exceeds a predetermined voltage.SELECTED DRAWING: Figure 2
