Abstract

An electrical cord retractor includes a closed hollow case separate from any apparatus with which an electrical cord will be used. Within the case is a winder, such as a rotatable spool, and the case is openable to permit an electrical cord to be wound upon the spool. The case wall has passageways through which an electrical cord can pass from the spool within the case to the exterior of the case, so that the cord can be connected to an apparatus independent of the case. The passageway may be slots which extend to a free edge of the case wall, so that after an electrical cord is wound on the spool, portions of the electrical cord extending from the spool can be inserted into the slots as the case is closed. The spool has a cord guide, in the form of a slot, extending from the external face of one of the spool flanges into the spool hub. A portion of an electrical cord is held stationary in the slot so that as the spool is rotated the remainder of the cord is wound upon the spool. The slot in the spool is arranged at an acute angle to the planes of the spool flanges, so that as the spool is rotated, the two portions of the cord extending from the slot will be wound on different sections of the spool hub. Within the case is a spring, constantly urging the spool to rotate in one direction, and a latch for releasably locking the spool against rotation.

Claims

1. An electrical cord retractor for use with an electrical cord already possessed by the user of the retractor, the retractor comprising:

a closed hollow case separate from any apparatus with which an electrical cord may be used, the closed case containing no electrical cord,

winder means within the case rotatable with respect to the case,

a spring within the case for constantly urging rotation of the winder means in one direction with respect to the case,

latch means within the case for preventing rotation of the winder means when the spring is tensioned, the latch means including a toothed wheel rotatable with the winder means, and a detent of springy material adapted to engage the teeth of the wheel to prevent rotation thereof,

manually-operable means for releasing the latch, said means including a single actuator element slidable with respect to the case, one end of the actuator being adjacent to the detent and the other end being exposed on the exterior of the case, the actuator being slidable in a direction transverse to the axis of rotation of the winder for engaging the detent and causing disengagement between the detent and the toothed wheel,

the case including a base and a cover,

means for releasably securing the cover to the base so that the case can be opened at will to permit an electrical cord to be wound upon the winder means, after which the case can be reclosed, and

passageway means in the closed case through which an electrical cord can pass rom the winder means within the case to the exterior of the case for connection to an apparatus independent of the case,

the passageway means being so formed that an electrical cord extending from the winder means can be inserted into the passageway means as the case is closed.

2. An electrical cord retractor as defined in claim 1 wherein one of the base and cover has a side wall surrounding the winder means, and the passageway means being formed in the side wall.

3. An electrical cord retractor as defined in claim 2 wherein the side wall has a free edge, and the passageway means is open at the free edge of the side wall to permit an electrical cord to be inserted laterally into the passageway means.

4. An electrical cord retractor as defined in claim 1 wherein the passageway means includes two separate slots in the case through which portions of an electrical cord adjacent to opposite ends of the cord can pass.

5. An electrical cord retractor as defined in claim 1 wherein the winder means has a cord guide for holding a short length of the cord stationary with respect to the winder means, so that as the winder means is rotated, the remainder of the cord is wound upon it.

6. An electrical cord retractor as defined in claim 5 wherein the winder means is a spool having a central hub and a flange at each end, the cord guide being a slot extending from the external face of one of the flanges into the spool hub.

7. An electrical cord retractor as defined in claim 6 wherein the flanges of the spool are in spaced apart parallel planes, and the base of the slot, from one end of the slot to the other, is at an acute angle to the planes of the flanges.

8. An electrical cord retractor as defined in claim 7 wherein both ends of the slot are in the region between the opposed faces of the flanges.

9. An electrical cord retractor as defined in claim 1 wherein the winder means includes an axial shaft, and the case has a bearing for rotatably accommodating the shaft.
