Abstract
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.
Claims10
A speed regulator for regulating a closing speed of an automatically closing slide door having a door roller, the closing speed of the slide door being regulated after the slide door has been manually opened, said speed regulator comprising:
- a generator activated by a rotation of said door roller for suppressing a rotational speed of said door roller;
- one-way clutch means for preventing transmission of, while said slide door is opening, and transmitting, while said slide door is closing, the rotation of the door roller to said generator;
- a resistor connected to an output of said generator;
- and
- speed change means for changing a closing speed of said slide door, at a predetermined position before a closed position of said slide door, from a first predetermined speed to a second predetermined speed which is slower than said first predetermined speed by changing a resistance value of said resistor.
A speed regulator for regulating a closing speed of an automatically closing slide door having a door roller, the closing speed of the slide door being regulated after the slide door has been manually opened, said speed regulator comprising:
- a generator activated by a rotation of said door roller for suppressing a rotational speed of said door roller;
- one-way clutch means for preventing transmission of, while said slide door is opening, and transmitting, while said slide door is closing, the rotation of the door roller to said generator;
- a resistor connected to an output of said generator, said resistor having a first resistor and a second resistor, the resistance value of said second resistor being smaller than that of said first resistor;
- and
- speed change means for changing a closing speed of said slide door, at a predetermined position before a closed position of said slide door, from a first predetermined speed to a second predetermined speed which is slower than that said first predetermined speed, said speed change means having switching means between said first resistor and said second resistor to change said resistance value of said resistor.
A speed regulator for regulating a closing speed of an automatically closing slide door having a door roller, the closing speed of the slide door being regulated after the slide door has been manually opened, said speed regulator comprising:
- a generator activated by a rotation of said door roller for suppressing a rotational speed of said door roller;
- one-way clutch means for preventing transmission of, while said slide door is opening, and transmitting, while said slide door is closing, the rotation of the door roller to said generator;
- a resistor connected to an output of said generator, said resistor having a first resistor and a second resistor, the resistance value of said second resistor being smaller than that of said first resistor;
- and
- speed change means for changing a closing speed of said slide door, at a predetermined position before a closed position of said slide door, from a first predetermined speed to a second predetermined speed which is slower than said first predetermined speed, said speed change means having switching means between said first resistor and said second resistor to change said resistance value of said resistor, at least one of said first and said second resistors being a variable resistor.
A speed regulator for regulating a closing speed of an automatically closing slide door having a door roller which rotates along a rail, the closing speed of the slide door being regulated after the slide door has been manually opened, said speed regulator comprising:
- a generator activated by a rotation of said door roller for suppressing a rotational speed of said door roller;
- one-way clutch means for preventing transmission of, while said slide door is opening, and transmitting, while said slide door is closing, the rotation of the door roller to said generator;
- and
- a resistor which is connected to an output of said generator and has a resistance value capable of reducing a closing speed of said slide door to a first predetermined speed.
