Abstract

An auto-feed/rewind electric cord reel device for controlling a power supply cord of an appliance includes a reel bracket on which a cord reel is rotatably mounted. A motor bracket is movably mounted in relation to the reel bracket and a linkage connects the reel bracket to the motor bracket. A first motor is included for selectively actuating the linkage and moving the motor bracket in relation to the reel bracket. A second motor is included and is spaced from the first motor. An assembly is driven by the second motor for selectively rotating the cord reel in at least one direction.

Claims

1. An apparatus for controlling a power supply cord of an appliance, comprising:

a reel bracket on which a cord reel is rotatably mounted;

a motor bracket movably mounted in relation to said reel bracket;

a linkage connecting said reel bracket to said motor bracket;

a first motor for selectively actuating said linkage and moving said motor bracket in relation to said reel bracket;

a second motor spaced from said first motor; and

,

an assembly driven by said second motor for selectively rotating said cord reel in at least one direction.

2. The apparatus according to claim 1, wherein said assembly comprises a pair of rotating members.

3. The apparatus according to claim 2, wherein said pair of rotating members include a first pulley, a second pulley, and a belt looped around said first and second pulleys.

4. The apparatus according to claim 3, wherein said reel bracket comprises an idler device, said idler device includes a rotatable wheel aligned with said belt and selectively contacting said belt.

5. The apparatus according to claim 4, wherein said reel bracket includes a pair of rollers rotatably mounted on said reel bracket.

6. The apparatus according to claim 5, wherein said pair of rollers includes a first roller and a second roller, said first roller being rotatably secured to an output shaft of said second pulley.

7. The apparatus of claim 6, wherein said first roller is positioned adjacent to said second roller, and wherein said first roller and said second roller each have a perimeter including a groove defined therein.

8. The apparatus according to claim 1, wherein said reel bracket comprises a slip ring assembly connected to said cord reel.

9. The apparatus according to claim 1, further comprising a sensor which senses an axial force on said cord corresponding to movements of said appliance.

10. The apparatus according to claim 9, wherein said sensor comprises an optical recognition sensor.

11. The apparatus according to claim 9, wherein said sensor comprises a push/pull gauge.

12. The apparatus according to claim 1, wherein the reel bracket includes a screw conveyor on which a cord guide is mounted.
