BACKGROUND OF INVENTION
Field of the Invention
The present invention relates generally to an apparatus for securing conduit to solar panel arrays that are typically installed on roof structures. More specifically, the assembly comprises a mount that is coupled to a solar panel module or a rail-less wire conduit structure for securing wire conduit alongside the perimeter of an array of solar panel modules. A method of installation is also disclosed.
Description of the Related Art
Any discussion of the prior art in the specification should in no way be considered as an admission that the prior art is widely known or forms part of common general knowledge in the field.
Installing a solar panel array on a roof can be challenging. One difficult aspect of the process is installing conduit that stores the wiring used as part of the solar panel array installation, and doing it in a manner that minimizes the visibility of the conduit on the roof in a simple and effective manner.
A typical conduit acts as a rigid passage to protect and assist in routing electrical wiring for the solar panel array. The most common conduit sizes for residential solar installations are ¾-inch and 1-inch conduits and are made from either metal (EMT) or PVC plastic.
There are three common installation techniques to install electrical wiring conduit. The first technique is a roof-mounted conduit as shown in FIG. 1. This technique mounts the conduit 120 to a roof 110 using wood, metal, or plastic blocks 100 coupled with fasteners or clamps 105 as shown.
The second technique mounts the conduit 120 directly to the roof 110 using flashings 130 as shown in FIG. 2. This technique typically includes a small mount 100 that is secured to the flashing 130 that also uses a mounting clip 150 to secure the conduit 120 to the mount 100 This technique is cumbersome to install and requires several extra parts as well. Another variation of the technique shown in FIG. 2 is the use of a conduit mount 170 that simply sits directly on top of a roof as shown in FIG. 3. The use of these mounts 170 keeps the conduit 120 open and viewable on the roof, which is not desirable.
The third technique utilizes a rail-mounted installation as shown in FIG. 4. This technique is used in rail-mounted solar panel arrays. The conduit 120 is mounted directly to the solar panel array structure 180 as shown.
Examples of standard conduit mounts 192, 194, 196, and 198 are shown in FIG. 5. Each of these mounts require a support structure to secure the mount to a roof.
The known prior art does not enable conduit to be secured directly to solar panel frames. The present invention overcomes these limitations and offers a solution that requires minimal parts and is easy to install, use, and manufacture.

DETAILED DESCRIPTION OF THE INVENTION
In the following description, and for the purposes of explanation, numerous specific details are provided to thoroughly understand the various aspects of the invention. It will be understood, however, by those skilled in the relevant arts, that the present invention may be practiced without these specific details. In other instances, known structures and devices are shown or discussed more generally in order to avoid obscuring the invention. In many cases, a description of the operation is sufficient to enable one to implement the various forms of the invention, particularly when the operation is to be implemented in software. It should be noted that there are many different and alternative configurations, devices and technologies to which the disclosed embodiments may be applied. The full scope of the invention is not limited to the example(s) that are described below.
FIG. 6 shows a top view of a typical rail-less solar panel array structure 200 supported by a series of rail-less support mounts 205. Line 215 indicates a proposed conduit path with dots 215 indicating possible locations where a conduit 120 can be installed along the solar panel array structure 200.
FIG. 7 illustrates a front and rear perspective view of an exemplary embodiment of the conduit mount 300. The conduit mount 300 comprises a c-shaped retainer 310 on a lower end that receives and holds a generally cylindrically shaped conduit 120. It is understood that the shape of the retainer is not limited to c-shaped retainers and that other similar shapes of retainers could be used as well. The upper end includes a top lip 320 and a middle lip 360 that forms a flexible and resilient first mouth 340. The upper end also includes a lower lip 370 that when combined with the middle lip 360 forms a second mouth 350 beneath the first mouth 340. The upper end also includes a resilient s-shaped structure formed by top surface 315, top lip 320, and bottom surface 325 and opening 330.
FIG. 8 illustrates an exemplary rail-less solar panel array support structure 400 that includes a solar panel frame 420 inserted on one side of the structure 400 and a wire management apparatus 430 on the opposite end of the rail-less support structure 400. The resiliency of the top lip 320 and middle lip 360 allows the first mouth 340 of the conduit mount 300 to be inserted onto a wide range of sizes and thicknesses of solar panel module flanges like the flange 410 shown in FIG. 8. The upper end can also be rotated 90 degrees so that upper end can be inserted into a wire management apparatus 430 by fitting the second mouth 350 over the terminating end 435 of the wire management apparatus 430 as shown in FIG. 8. The resiliency of the s-shaped structure enables the upper end to conform more snuggly to within the wire management apparatus 430.
Each type of installation is a two-step process. When securing the conduit mount 300 to the solar panel module 420, the first step is to pull the conduit mount 420 onto the solar panel frame flange 410 through the first mouth 340 as shown in FIG. 9. The next step is to pull the conduit 160 into the c-shaped retainer 310 of the conduit mount 300 as shown in FIG. 10. No tools are typically needed to complete the installation.
FIG. 11 shows a perspective view of the rail-less support structure 500 focusing on the side that includes the wire management apparatus 430. The conduit mount 300 can also be installed in a wire trough 440 of the wire management apparatus 430. The wire trough 440 in this exemplary embodiment is a J-shaped structure that includes the terminating end 435.
The installation is also a two-step process. The first step is sliding the conduit mount 300 into the wire trough as shown below in FIG. 12. This is accomplished by either inserting the upper end of the conduit mount 300 so that the terminating end 435 of the J-shaped structure fits into the second mouth 350 so that the s-shaped structure fits within the trough 440 and the middle lip 360 and the lower lip 370 fit snuggly on to the terminating end 435. The last step involves inserting the conduit 160 into the c-shaped retainer 310 as shown in FIG. 13. Essentially no tools are necessary to complete the installation process.
FIG. 14 illustrates a front and rear perspective view of an alternate exemplary embodiment of the conduit mount 600. In this embodiment, the conduit mount 600 provides for the conduit mount 600 to be installed solely on the solar panel module frame flange 410. The shape of the upper end has been slightly altered to provide only the clip function with a slot 385 and includes top lip 380 and bottom lip 390 to form the c-shaped mouth that is resilient so that it can be secured to the solar panel frame flange 410 without the need for any additional tools. The conduit mount 600 also includes the c-shaped retainer 310 for receiving the conduit 160.
