DETAILED DESCRIPTION OF THE INVENTION

While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail one preferred embodiment, with the understanding that the present disclosure is to be considered merely an exemplification of the principles of the invention and the application is limited only to the appended claims.

Referring now to the drawings, and particularly to FIGS. 1 through 10, there is shown a preferred embodiment of the present invention. The vehicular light of the present invention, generally designated by the number 10, is shown as having a reel assembly 12 and a light assembly 14. While the light is disclosed as being attachable to a vehicle surface, it is appreciated that it may be attached to other surfaces and not depart from the scope of the present invention.

As shown in FIGS. 1 thorough 5, the reel assembly 12 comprises a housing 20, and a female outlet or connector 22 and a male plug or connector 24 connected by a conventional electrical cord 26. In this example, the connector is a 12V receptacle and the plug is a 12V plug. The housing is preferably formed from a bottom member 28 and a top member 30 that are attached together. Referring to FIGS. 2 and 3, the top member of the housing may include a plurality of holes or recesses 32 spaced about its perimeter that permit a plurality of screws or other threaded fasteners (not shown) to extend through and engage a plurality of threaded holes 34 on the bottom member 28. The top member 30 may also include one or more pins 36 for engaging corresponding holes 38 on the bottom member 28 to facilitate the proper alignment of the housing member 28, 30 during the attachment process. While the reel housing is shown as substantially circular, it is appreciated that it may be of a variety of shapes including, but not limited to, circular, oval, square or triangular and not depart from the scope of the present invention.

Referring again to FIG. 3, the reel assembly 12 includes a disc 40 having a hole extending through the center, a plurality of angular teeth 42 positioned on the periphery of on one side of the disc, and a sleeve 44 extending about the hole on the other side of the disc. Together with the sleeve 44, a pair of curved walls 46, integrally formed on the disc 40 and spaced apart from the sleeve 44, form a reel for winding and unwinding the cord 26 through openings 48 in the housing.

The bottom member 28 of the housing preferably includes a substantially circular wall 50 integrally formed on the inner side therein for defining a recess or chamber for accepting an insert 52. The circular wall may have a plurality of curved slots 54 spaced apart along its circumference for accepting corresponding sleeves 56 on the insert member to maintain the insert in place. A hole 58 in the center of the insert 52 is sized to accommodate the base of a spindle 60. A cover 62 preferably includes a plurality of holes 64 about its periphery to permit screws or other fasteners to be inserted therethrough and into the corresponding sleeve 56 of the insert 52 to attach the cover 62 and insert 52 together.

A clip 70 is biased by a spring 72 towards the ratchet teeth 42 on the disc 40 to promote engagement of the ratchet teeth 42 and the clip 70 to normally retain the cord 26 in place. The angled face 74 of the teeth 42 permits the clip 70 to sequentially move over the engaged tooth 42 to engage the next tooth 42, thereby permitting the cord 26 to be withdrawn from the reel assembly 12. A spring (not shown) associated with the disc 40 in a known way normally biases the disc 40 in a clockwise direction so that the flat wall 76 of one of the teeth 42 engages the clip 70 to prevent the cord 26 from being retracted through the openings 48 into the reel assembly 12. Disengagement of the clip 70 from the teeth 42 may be accomplished by depressing a button 78 on the reel housing which overcomes the force of the spring 72 and biases the clip 70 out of engagement with the teeth 42. Once the clip 70 is removed from engagement with the teeth 42, the spring associated with the disc 40 acts to rotate the disc 40 and thereby retract the cord 26 into the reel housing 20. In particular, the spring may be attached to the spindle such that as the cord is pulled from the housing, the spring will be wound in a way such that depression of the button will permit the spring to return to its initial state and wind the cord.

The housing 20 preferably includes a pair of flanges 80 to permit the female outlet 22 and male plug 24 to be removably attached thereto for storage and use. In the preferred embodiment, the flanges have a substantial T-shaped cross-section for mating with channels 82 extending longitudinally along the female outlet 22 and male plug 24.

The male connector may be any of the known types of connectors for transmitting power, but is preferably a male adapter or connector for engaging a vehicular cigarette light or other similar outlet in a vehicle, home or elsewhere to provide power to the light assembly. Similarly, the female outlet may be any of the known types of outlets for accepting male plugs or connectors, but is preferably a female outlet for accepting a male adapter of the type shown with respect to light assembly 14 and disclosed herein. A cover or cap 84 may be removably attached to the female outlet 22 to prevent dust and other contaminants from damaging or otherwise adversely affecting the electrical contacts in the female outlet. While a male plug and female outlet are shown and disclosed, it is appreciated that the reel assembly may comprise a pair of male plugs or a pair of female outlets, depending upon the plug it will mate with at the power end and/or the light assembly end, and not depart from the scope of the present invention.
