Self-closing sliding door governor

摘要

Disclosed is a speed regulator for an automatically closing slide door for regulating a closing speed of an automatically closing slide door which is closed automatically, comprising; a generator associated with said slide door; an one-way clutch means for converting a linear movement caused during a closing motion of said slide door into a rotational movement and for transmitting said rotational movement to said generator; a resistor connected to an output of said generator; and a speed change means for changing said closing speed of said slide door, at a predetermined position before the closed position of said slide door, from a first predetermined speed to a second predetermined speed slower than said first predetermined speed by changing a resistance value of said resistor.
