  • Not Applicable
  • BACKGROUND OF THE INVENTION
  • This invention relates generally to the field of outdoor umbrella accessories and more specifically to an umbrella light.
  • Outdoor umbrellas have been used in residential and commercial settings for many years. Traditionally they serve the purpose of creating comfortable shade in an otherwise sunny, hot environment. However, in recent times it has also become popular to use outdoor umbrellas during evening activities such as having an outdoor dinner or other evening event. It is desirable to have a source of illumination during such evening events.
  • To this end, the addition of a lighting fixture to the underside of an umbrella, which could shine light down on a table and surrounding people or other objects would be desirable. Another desirable feature would be a lighting source that, by using batteries as a power source, did not require to be plugged into a standard 120 VAC outlet. And even more desirable would be a lighting fixture that used the sun as a means of recharging its battery source.
  • A number of inventors have anticipated this problem and suggested potential solutions. These include U.S. Pat. No. 6,612,713, U.S. Pat. No. 6,966,667 and patent applications 2005/0117326, 2004/0149325. However, each solution described in prior art includes certain deficiencies that the present invention overcomes. None of the above patents or applications describes a way to easily attach an umbrella light to an existing standard umbrella in a way which universally requires no assembly, tools or closure buckles. None include a combination of independently controlled cool white and amber LED's for optimum color balance, and none uses a choice of AA or C type batteries. Finally, none includes an umbrella attachment clip to easily attach a solar panel to the outside fabric of a standard umbrella.
  • BRIEF SUMMARY OF THE INVENTION
  • The primary object of the invention is to provide an umbrella light that derives electrical power from a DC battery source located within the light housing.
  • Another object of the invention is to provide a fully assembled umbrella light that can be easily attached, by means of a single torsion spring, at any desired height to the support pole of an outdoor umbrella.
  • Another object of the invention is to provide an umbrella light whose color output can be balanced using a combination of independently adjustable cool white and amber LED's.
  • A further object of the invention is to provide an umbrella light that allows easy attachment of a solar panel to the fabric portion of an umbrella and includes an electrical cable that feeds power to rechargeable batteries located within the light housing.
  • Another object of the invention is to provide an umbrella light that can alternately be hung on any convenient hook for non umbrella pole applications.
  • Yet another object of the invention is to provide an attachment means for an umbrella light that requires no tools or buckles to install.
  • Still yet another object of the invention is to provide an umbrella light that can accommodate C or AA type batteries.
  • Another object of the invention is to provide a charging system that uses an integrated circuit instead of a light sensor to manage use between the solar cell and battery operations.

  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner. Referring now to FIG. 1 we see a perspective view of the invention 100 attached to a standard umbrella 2. It consists of housing 50 that is doughnut or other shaped so that it can attach to a standard umbrella pole 6. A pair of coiled insulated wires 20 travel from the housing 50 to a solar panel 10 located on the outside of the umbrella fabric and held in place by solar panel clip 8. The coiled nature of the insulated wires allows for adjustment in height of the light housing 50 without the need for additional wire retaining ties or clips. FIG. 2 shows a partial side section view of umbrella 2 and wind vent portion 4. Attached housing 50 is comprised of two permanently hinged opposing housings 50A and 50B. The housing 50 can also be attached to slide-able collar 22 so that the housing 50 can raise and lower along with the umbrella portion 2. This means that the housing does not have to be removed when the umbrella 2 is in the lowered or stored position. Most outdoor umbrellas have wind vents 4. The present invention takes advantage of the interruption in fabric created by the wind vent 4 to attach solar panel clip 8 in place by U shaped spring biased portion 8A. The extended length, approximately five inches, of clip arm 8 accommodates the overlap in material formed by the wind vent 4 as it overlaps the main umbrella 2 and allows solar panel 10 to be in full view of the sky without being covered by the wind vent flap 4. Other methods of holding solar panel 10 onto umbrella 2 include a standard pin and clasp method where a pin located on the back of solar panel 10 would penetrate the fabric of umbrella 2 and be held by a clasp. Another method includes having an aperture in the frame of solar panel 10 that can be placed between the top of the umbrella 2 and the top finial 5, which can be unscrewed and re-screwed for this purpose. For attaching the solar panel 10 to an umbrella that does not have a wind vent flap, a pocket type attachment made of cloth or plastic can be provided to the user for attachment by glue, magnetic clasp or sewing to the exterior of the umbrella surface. The pocket can then accept the clip end 8A of solar panel clip holder 8. FIG. 3 shows a bottom view of the housings 50A and 50B. LED lights 30, 32 emit light from corresponding apertures in housing 50A, 50B. The LED lights are alternating in color. Half are cool white 30 and half are amber 32. On/off selector switch 34 allows the user to select whether both amber 32 and cool white 30 are on together, or one or the other light up separately. By mixing both amber 32 and cool white 30, a balanced warm light is generated which makes skin tones and food look more appealing. Additionally, if the user chooses to use only cool white 30 or only amber 32, the batteries will last twice as long as when using both together. The combination of hinged torsion spring 44 and resilient bumpers 36 allow poles 6 of widely differing diameters to be held snuggly within aperture 34. FIG. 3 also shows wire hanger 39 which can be inserted into slots 35, 37 and can act as a hanger means for non umbrella applications such as when hanging on a hook within a camping tent. FIG. 4 shows an exploded view of housings 50A and 50B. Torsion spring 44 is placed over tubular post 48. The top end of spring 44 rests in cradle 42. The bottom end of spring 44 rests in cradle 52. Post 46 of the bottom plate 50B2 can penetrate aperture 40 to form a shaft for allowing housings 50A and 50B to be hingedly joined. The torsion spring 44 is biased inward so that housings 50A and 50B tend to be forced in towards each other thereby allowing umbrella pole 6 to be securely held. To attach housing 50A,B the user simply pulls the housings apart until the umbrella pole 6 can fit in the center portion 34, and then releases the housings 50A,B allowing them to spring inward and grasp the pole 6 by resilient pads 36. FIG. 5 shows a perspective view of the housing 50A,B with components in place. C type batteries 62 provide much longer illumination periods in comparison to AA type batteries. The present invention can operate on C batteries without any solar charging accessories, or can operate on rechargeable C batteries and an associated solar charging system as shown in the present drawings. Additionally, as shown in FIG. 7, hinged AA battery support members 80, 82 can be deployed within C type battery holder 72, 72A so that the unit may run on either C type batteries or AA type batteries. IC circuit 60 measures input voltage from solar panel 20 to the battery. When the input voltage reaches approximately zero at dusk, it instructs the batteries to connect to LED lights 30, 32 to turn on. This is a more precise and efficient way to maximize solar recharging and to sense when to turn on the lights as compared to the more common photo sensor method. PC boards 64, 66, 68, 70 all support LED's 30, 32 in the standard way. Metal battery contacts 72, bring power from standard recharging circuit, not shown, to rechargeable C or AA batteries 62. Adaptor socket 74 allows a person to plug in either solar power cable 20 or to plug in an adapter cable that can provide power to the rechargeable batteries 62 or directly to LED's 30, 32 via an AC to DC wall converter. FIG. 6 is a perspective view of the solar panel 10 and attached solar panel attachment clip 8, 8A. Extension arm 8B is approximately five inches long and allows the solar panel to rest on the surface of umbrella 2 so that vent flap 4 will not cover the panel 10 thereby increasing the ability of the panel 10 to absorb the day light.
  • While the invention has been described in connection with a preferred embodiment, it is not intended to limit the scope of the invention to the particular form set forth, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.
