Abstract

A decorative solar energy collector includes tubular elements extending from the base at a bottom end. The tubular elements extend closely adjacent each other along a middle section to form a trunk-like appearance, and then diverge at a top section, so that each tubular element forms a branch-like appearance. Solar panels are provided, with one solar panel affixable adjacent a top end of a tubular element. Each solar panel collects solar energy and converts the solar energy into electricity. The solar panel includes a connector and circuitry for transmitting electricity to the connector. The number of solar panels is no greater than the number of tubular elements. Cables are also provided, one cable extending through a lumen of each tubular element in connecting relation between a solar panel connector at the cable's top end and the base at the cable's bottom end.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A description of the preferred embodiments of the present invention will now be presented with reference to FIGS. 1-13.
The solar energy collection device 10 of the present invention is designed to resemble a tree. The device 10 comprises a base, which in a first embodiment (FIG. 2) includes a placement base 11 having bolt or screw holes 12 for permitting the placement base 11 to be affixed to a surface 90. Alternatively, the placement base 11 may simply rest on a surface 90. Above the placement base 11 is affixed a trunk platform 13 having a plurality of holes 14 through a top end 15 thereof and a cable opening 16 through a side wall 17 thereof. Alternatively, this base embodiment could comprise a unitary element comprising the placement base and trunk platform.
A second embodiment of the base (FIGS. 1 and 3) comprises a placement base 21 having bolt or screw holes 22 for permitting the placement base 21 to be affixed to a surface 90. Alternatively, as above, the placement base 21 may simply rest on a surface 90.
Atop the placement base 21 is rotatably affixed a rotating base 23 that has an interior space 24. The rotating base 23 has a plurality of openings 25 at a top end 26 extending into the interior space 24 and a cable opening 27 that extends from the interior space 24 to the exterior for passing a power cable 28 therethrough. Preferably the rotating base 23 is adapted to rotate through approximately 180°.
A plurality of tubular elements 30 extend from the base at their bottom ends 31. The tubular elements 30 extend closely adjacent each other along a middle section 32 to form a trunk-like appearance. The tubular elements 30 diverge at a top section 33 to form a branch-like appearance. In a particular embodiment, the tubular elements 30 flare outward along a bottom section 34 to form a root-like appearance.
In one embodiment (FIG. 1), the tubular elements 30 extend in substantially vertical fashion along the middle section 32. In another embodiment 10′ (FIG. 4), the tubular elements 30′ are twisted about one another along the middle section 32′.
A plurality of solar panels 40 are provided (FIGS. 1 and 5), in a particular embodiment KC-series solar panels of Kyocera (Japan). Each solar panel 40 comprises at least one solar cell 41 housed in a frame 42. The solar cell 41 is adapted to collect solar energy and convert the collected solar energy into electricity. Each solar panel 40 further comprises a connector 43 and circuitry 44 for transmitting electricity from the solar cell 41 to the connector 43. Each solar panel 40 is affixable adjacent a tubular element's top end 35, at most preferably one solar panel 40 per tubular element 30. Thus there are at least as many tubular elements 30 as there are solar panels 40.
Preferably the solar panels 40 are arrayed for optimizing solar energy collection. For example, preferably the solar panels 40 are arrayed in substantially nonoverlapping fashion when viewed along an incoming solar ray vector, such as when viewed from a position approximately above the device 10. As an example, the device 10 of FIG. 6 is shown in top projection in FIG. 7, wherein the solar panel levels 1-5 are shown as extending increasingly farther out from the “trunk” as one proceeds upward. Thus a first set of solar panels 40 in a preferred embodiment extend farther outward from the tubular element middle section 32 than a second set of solar panels 40 positioned farther from the base than the first set of solar panels 40. In particular, the solar panels 40 are arrayed to form a substantially dome-shaped aspect when viewed from the side (FIG. 8).
The device 10 additionally comprises a plurality of cables 50 (FIG. 3). Each cable 50 extends through a lumen 36 of each tubular element 30 in connecting relation between a solar panel connector 43 at the cable's top end 51 and the base at the cable's bottom end 52. The base's holes 25 are for admitting the cable's bottom ends 52 into the rotating base interior space 24.
The device 10 also comprises a coupler 53 that receives the cable's bottom ends 52 and outputs a unitary power cable 28. The coupler 53 is housed in the interior space 24, and the power cable 28 extends to the exterior through the cable opening 27.
In order to enhance the tree-like appearance of the device 10, a plurality of leaf elements 61 are affixed along at least some of the tubular elements 30, either or both along the middle section 32 or the top section 33. In addition, an ivy-like element 62 can be added along the middle section 32 and/or the top section 33, as depicted in FIG. 13, to further enhance the tree-like appearance of the device 10.
In a third embodiment (FIGS. 9-12), the device 10 additionally comprises a solar sensor 54 (FIG. 9) that is affixed to a tubular element 30 and is adapted to sense a directionality of incoming solar energy. A motor (not shown) is also provided in the interior space 57 for rotating the rotating base 58 responsive to a directionality signal transmitted by a signal cable 56 from the solar sensor 54 through the tubular element 30 to which the sensor 54 is affixed. The tracking rotor 55 is shown in FIG. 10, as encased in a third embodiment of the base 59 (FIGS. 11 and 12), the interior space 57 to which is accessed via access lid 60. This embodiment optimizes a collection of solar energy by the solar panels 40 by turning the device 10 to position the solar panels 40 to face the sun optimally.
The solar energy collection device 10 of the present invention is thus designed to resemble a tree, which permits the device 10 to appear coherent with the environment as well as to portray an aspect of simulated form and function. Thus the “leaves,” i.e., solar panels, of the “tree” collect solar energy and convert it to useful electrical energy. The “trunk” and “branches” of the tree support the energy-gathering elements, the solar panel “leaves,” and also serve as conduits between the “roots” and the “leaves.” It may be appreciated by one skilled in the art that additional embodiments may be contemplated, including other environmentally suggestive sculptures such as bushes and shrubbery.
In the foregoing description, certain terms have been used for brevity, clarity, and understanding, but no unnecessary limitations are to be implied therefrom beyond the requirements of the prior art, because such words are used for description purposes herein and are intended to be broadly construed. Moreover, the embodiments of the apparatus illustrated and described herein are by way of example, and the scope of the invention is not limited to the exact details of construction.
Having now described the invention, the construction, the operation and use of preferred embodiments thereof, and the advantageous new and useful results obtained thereby, the new and useful constructions, and reasonable mechanical equivalents thereof obvious to those skilled in the art, are set forth in the appended claims.
