Method of using solar panel support apparatus

Abstract

A method of using a solar panel support apparatus for selectively positioning a solar panel contained thereon comprises securing forward and rearward legs to the ground or an affixed structure. A solar panel is supported by a rack having an end pivotally attachable to the forward leg. First and second arms pivotally connected to one another pivotally attach to the forward leg and the rack permitting the rack to be positionable relative the forward leg. A locking mechanism locks the first arm and the second arm at a selected angle relative to one another, whereupon securing the rearward and the forward leg to the ground or an affixed structure the rack is pivotal to position the solar panel. Upon positioning the rack to place the solar panel at a selected position, the locking mechanism is engaged to retain the solar panel at the selected position.

DESCRIPTION OF THE INVENTION

(7) A solar panel support apparatus in accordance with the present invention is generally indicated at 10 in FIG. 1. The apparatus 10 generally comprises a base frame assembly 12 supporting a pivotally attached rack frame 14 for supporting one or more solar panels or arrays 16. As best illustrated in FIGS. 2 through 4, the base frame assembly 12 includes a pair of spaced-apart rearward legs 18, each respectively pivotally attached to a pair of spaced-apart front legs 20 by means of a bracket 22 and accompanying pin or bolt 24. The rear legs 18 are supported by a brace 26 including a first segment 28 and a second segment 30 pivotally attached at central portions thereof and secured to the rear legs 18 by pins or bolts 32. Anchoring foot pads 34 and pins or bolts 36 are provided to pivotally secure each leg 18, 20 to the ground or any other suitable affixed structure, including a rooftop, post, footing or side of a building. To accommodate nearly every conceivable terrain or affixed structure, both the forward legs 20 and the rearward legs 18 are telescoping to independently increase or decrease their overall length. This is accomplished by means of a first top portion 38 for rear leg and 39 for forward leg slidably disposed within a second bottom portion 40 for rear leg and 41 for forward leg. Preferably, the top portion 38, 39 are provided with a variety of pre-drilled apertures 42 at varying locations for receiving a pin 44 therethrough to be mated with a corresponding aperture in the respective bottom portion 40, 41. It should be noted, however, that providing a plurality of apertures 42 in the bottom portion 40 to be mated with an aperture of the top portion 38 is well within the scope of the present invention. It should be further noted that it is well within the scope of the present invention that the end-user drill apertures to customize the positioning of the first top portion 38 relative to the second bottom portion 40 to adjust the height of each leg 18, 20. In this manner each forward leg 20 and rearward leg 18 can be independently adjusted to account for varying terrain or heights of a structure to which the base frame assembly 12 is securable.

(8) The rack frame assembly 14 preferably includes a rectangular formation having opposing top and bottom members, 46 and 48, respectively attached to opposing side members 50 with use of brackets. The rack frame 14 is designed to be field adjusted by the end user to accommodate solar panels or arrays 16 of varying dimensions and from various manufactures. Optional horizontal and vertical cross members, 52 and 54, respectively, may be provided to secure solar panels or arrays 16 to the rack frame members 46, 48, 50. Brackets 56 permit pivotal attachment of a top portion of the rack frame assembly 14 to the forward legs 20, and in particular the top portions 38 of the forward legs 20. Opposing sides of a bottom portion of the rack frame assembly 14 each connect to respective forward legs 20 by means of a rack support assembly 58.

(9) The rack support assembly 58 includes a forward arm 60 pivotally connected to the racking frame assembly 14 by means of a bracket 62, and a rearward arm 64 pivotally connected to the respective forward leg 20 by means of a bracket 66. Preferably, proximal end of forward arm 60 pivotally connects to the lower portion of the rack frame assembly 14, and proximal end of rearward arm 64 pivotally connects to the lower portion 40 of the forward leg 20. It should be noted though that it is well within the scope of the present invention to attach the forward arm 60 at differing locations along respective side members 50 of the racking frame assembly 14, as well as attach the rearward arm 64 at differing locations on the forward leg 20. The forward arm 60 and the rearward arm 64 pivotally connect to one another at distal ends where they can be locked to one another by means of a locking mechanism 68. The locking mechanism 68 includes opposing ears or plates 70 extending from the rearward arm 64 and spaced-apart from one another so as to receive the forward arm 60 therebetween. Alternatively, as one skilled in the art will recognize, it is well within the present invention to provide the ears 70 attached to the forward arm 60, with the rearward arm 64 disposing therebetween. Each ear 70 contains corresponding apertures 72 for receiving a pin 74 disposable through a cooperating aperture 76 positioned through the forward arm 60 to pivotally attach the forward arm 60 to the locking mechanism 68. When installed, the rack support assembly 58 preferably permits the rack frame assembly 14 to be positionable relative to the forward leg 20 between zero degrees, or parallel to the forward leg 20, and 90 degrees, or perpendicular to the forward leg 20, and an infinite number of positions therebetween. It should be noted, though, that it is well within the scope of the present invention to either modify the length of the forward and rearward arms, 60 and 64, respectively, or the positioning of the attachment of the forward and rearward arms, 60 and 64, respectively, to respective racking frame assembly 14 and forward leg 20 to modify the positioning angle of the racking frame assembly 14 relative to the forward leg 20 to go beyond 90 degrees.

(10) To lock the rack frame assembly 14 at a selected position, two methods are described. The first method accommodates an infinite number of positions of the rack frame assembly 14 within the arc range thereof. As is known in the art, the preferred angle of the solar panel or array 16, and thus the rack assembly 14, is first determined. Upon determining the selected position of the rack frame assembly 14, the user drills a second set of corresponding apertures 78 through each ear 70 of the locking mechanism 68 and a second aperture 80 through the forward arm 60 at the selected position of the rack frame assembly 14. A second pin 82 disposable through the second set of apertures 78 and the second aperture 80 prevents pivotal movement of the forward arm 60 about the rearward arm 64, and the two are locked in place. If later another positioning of the rack frame assembly 14 is desired, the user simply drills another set of cooperating apertures in the same manner as described to accommodate the updated selected position, as illustrated in FIG. 5. Alternatively, a second method includes providing one or more additional sets of cooperating apertures 78 through the ears 70 and for receiving the second pin 82 to lock the rack frame assembly 14 at a pre-selected position. The second method could accommodate a wide variety of preselected positions within the arc range of the rack frame assembly 14, and may allow for more than one positioning depending on specific needs of the user. Using either the first method or the second method, once the second locking pin 82 is properly positioned, movement of the forward arm 60 relative to the rearward arm 64 is not permitted, and the racking frame assembly 14 is locked into place at the selected position.

(11) Alternatively, it is well within the scope of the present invention to remove the rear legs 18 and attach only the forward leg 20 a fixed structure, for example a vertical wall of a building. The racking frame 14 and rack support assembly 58 remain and operate as previously described.

(12) It is recognized there are multiple variations beyond what are outlined in the detailed description to accomplish the objectives set forth by the current invention. Further alternative embodiments provide additional utility of the device for the convenience of the user. As such, although the present invention has been described with reference to preferred and alternative embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.
