Abstract
A device for paying out and retracting an electric power cord (4) comprising two driven cord winder members, the first member being a cord winding reel (1) and the second member being a drive element (7, 8) for engaging the cord (4) at a distance from the reel (1). An electric motor (20) can drive one of the two cord winder members in two directions and is connected with driving force to the other cord winder member (7, 8) by way of a slipper clutch (13) and a one-way clutch (12).
Claims10
A device for paying out and retracting an electric power cord, comprising an electric motor and two driven cord winder members, the first cord winder member being a cord winding reel and the second member being a drive element for engaging the cord at a distance from the winding reel, wherein the motor can drive the drive element in two directions, wherein the motor is connected with driving force to the drive element by way of a slipper clutch and a one-way clutch such that said drive element can be driven by the motor in a retraction direction through the slipper clutch while said drive element can be driven by the motor in a payout direction through the one-way clutch and is therefore free to move in the payout direction at a speed lower than the driving speed caused by the motor, the lower speed of the drive element thereby determining the speed of the cord in the payout direction.
A method of paying out and retracting an electric power cord, wherein the cord is paid out and retracted by a device comprising an electric motor and two driven cord winder members, the first member being a cord winding reel and the second member being a drive element engaging the cord at a distance from the reel, and wherein the motor drives one of the two cord winder members, the method comprising:
- driving, via the motor and slipper clutch, the drive element in a retraction direction,
- driving, via the motor and one-way clutch, the drive element in a payout direction, wherein the drive element is free to move in the retraction direction at a speed lower than the driving speed caused by the motor.
A device for paying out and retracting an electric power cord, comprising an electric motor and two driven cord winder members, the first cord winder member being a cord winding reel and the second member being a drive element for engaging the cord at a distance from the winding reel, wherein the motor can drive the winding reel in two directions, wherein the motor is connected with driving force to the winding reel by way of a slipper clutch -and a one-way clutch such that said winding reel can be driven by the motor in a retraction direction through the slipper clutch while said winding reel can be driven by the motor in a payout direction through the one-way clutch and is therefore free to move in the payout direction at a speed lower than the driving speed caused by the motor, the lower speed of the drive element thereby determining the speed of the cord in the payout direction.
