Abstract

A reel for storing an extendable, retractable electrical power cord, signal cable or fluid conducting hose wherein electrical or fluid continuity is maintained throughout the process of storage and extension of the device without resort to the use of brushes, slip rings or relatively movable couplings.

Claims

1. A retractable self-storing reel for an elongated means such as an electrical cord, signal cable, fluid conducting hose and the like comprising:

a casing,

a reel journaled for rotation in said casing,

a spring mounted within said casing to extend between said casing and said reel for rotatively biasing said reel in one direction,

a ratchet means comprising a pawl extending between the inside periphery of said casing and said reel for restraining the rotational movement of said reel in said first rotative direction,

a first means for providing an entranceway into said casing for the elongated means coaxially of said reel,

said elongated means comprising a first part having a coiled portion one end of which extends into said entranceway, the remainder of said coiled portion extending outwardly of said entranceway

said first means comprising a clamp for snugly engaging and clamping the elongated means with said reel

a second means providing an outlet in said casing for the elongated means in an area juxtapositioned the periphery of said reel, and a second uncoiled part of said elongated means extending from said coils in said entranceway to said reel and wound therearound with the free end of said second part extending from the periphery of said reel through said outlet and out of said casing.

2. The retractable self-storing reel set forth in claim 1 wherein:

said elongated means comprises an electrical conductor.

3. The retractable self-storing reel set forth in claim 1 wherein:

said elongated means comprises a signal transmitting cable.

4. The retractable self-storing reel set forth in claim 1 wherein:

said elongated means comprises a fluid conducting hose.

5. The retractable self-storing reel set forth in claim 1 wherein:

said spring comprises a spiralled compression spring coaxially mounted in a cavity formed in said reel.

6. The retractable self-storing reel set forth in claim 5 wherein:

said elongated means is wound on said reel at a greater radial distance from the axis of said reel than the coils of said spring.

7. A method of extruding and retracting an elongated member comprising the steps of:

winding a center portion of an elongated means around a reel biased in one direction to maintain said center portion on said reel,

coiling one end portion of said elongated means and extending it axially outwardly of said reel,

holding firmly one or more coils of said elongated means to said reel,

extending the other end of said center portion of said elongated means outwardly of the periphery of said reel,

whereby when said other end of said elongated member is pulled to unwind said elongated member from said reel against the biasing action of said reel said coiled end of said elongated member partially uncoils.

8. The method set forth in claim 7 wherein:

said elongated member comprises an electrical conductor.

9. The method set forth in claim 7 wherein:

said elongated member comprises a fluid conducting hose.
