Abstract

PURPOSE: To easily open and close a door through a simple construction, by combining rollers with circular rotors which rotate in coaxial connection with knobs of the door.
CONSTITUTION: Turning a knob 3a counterclockwise, a rotor 4a fixed on a shaft 7 swings by a prescribed angle and rollers 8 placed in contact with the rotor are separated from projections 10 of the rotor by the restoring forces of springs 9 and brought into contact with curved parts 11 of the rotor. At that time, vertically moving shafts 13 fixed on roller supports 12 are moved on guides 14 and pulled out through bearings 16 or bearing holes 17 provided in a frame. However, the other rotor 4b swings clockwise and stops on a stopper 18. At that time, projections of the rotor 4b push the other rollers so that other vertically moving shafts are coaxially moved in the opposite direction and inserted into bearing holes. As a result, the latter vertically moving shafts act as rotary shafts which support the door to be opened.
