Abstract
In various representative aspects, an apparatus for clamping and grounding an upper and lower solar panel mounting rail is disclosed herein. The apparatus comprises a fastener with an enlarged end, and a shank, with the enlarged end having one or more sharp protrusions that resemble teeth, and a washer with one or more sharp protrusions, and an opening. When installed, the shank is inserted through the opening of the washer, the sharp protrusions of the enlarged end penetrate either the lower or upper mounting rail and the sharp protrusions of the washer penetrate the other mounting rail while at the same time creating a grounding path through the apparatus.
Description
- The present invention relates generally to providing an apparatus for clamping multiple objects together and providing a grounding path between the objects. More specifically, the invention relates to providing a way for the assembly to penetrate metallic objects to better secure the assembly when clamping the objects together while at the same time providing a grounding path between them. One exemplary application of the assembly is to affix a solar panel frame to a rail.
- Existing solutions are either unsatisfying in providing sufficient electrical grounding capacity or too complicated to manufacture or install. For example, U.S. Pat. No. 5,006,074 (Franks) teaches an adjustable clamping device using a threaded bolt with an abrading surface to penetrate an outer surface to ground a conductor. The device is not designed to affix two or more objects. US patent application, publication number US 2011/0039430 A1 (Aftanas), discloses a fastening assembly with a metallic bolt and a metallic leaf spring. The metallic leaf spring has at least one tooth projecting from one of the opposing ends. The tooth may penetrate the solar panel frame or the support frame member and ground the solar panel frame. Because the leaf spring is non-structural it only has the capacity to clamp objects together while at the same time providing a grounding path between them.
- Another example is US patent application, publication number US 2011/0179606 A1 (Magno et al.), which discloses an assembly for clamping two objects with a single hand and for grounding the objects. Because the assembly has many unnecessary parts (such as a channel member and a clamp with a three-prong first member, a washer, a nut, a threaded bolt, a spring, and a torsion spring) the design is unnecessarily complex. Thus, a less complex assembly that provides grounding and is both easy to use and manufacture is desired.
- The invention is summarized below only for purposes of introducing embodiments of the invention. The ultimate scope of the invention is to be limited only to the claims that follow the specification.
- It is an object of this invention to provide a mechanism for fastening two or more objects together and providing a grounding path between the objects that is both easy to manufacture and install.
- An embodiment of this invention comprises a fastener and a washer for clamping at least two objects. The fastener may have a shank and an enlarged end with one or more raised portions for penetrating a first object. The washer has an opening and also one or more raised portion for penetrating at least one other object. The raised portion may be a tooth or other similar structure as long as it has a sharp ridge, or any kind of configuration that is suitable for penetrating metallic surfaces. When installed, the shank is disposed through the opening of the washer.
- An example of the fastener is a t-bolt comprising a head (an enlarged portion) and a shank, with teeth protruding from the head. The embodiment may be used to clamp a solar panel frame to a rail by enabling the teeth of the t-bolt to penetrate into the rail and the teeth of the washer penetrating into the solar panel frame so that the embodiment provides a secure grip. If a proper force is applied during assembly, the teeth of the t-bolt may penetrate through the coated surface of the metallic rail while the teeth of the washer may penetrate through the coated surface of the metallic solar panel frame. A grounding path is then formed from the solar panel frame to the rail via the washer and the t-bolt.
- In this embodiment, the t-bolt and the washer may be coupled by the external thread of the t-bolt and internal thread of the washer's opening. Alternatively, a threaded nut may be used to fasten the washer to the t-bolt. The washer may be flat or may comprise of one or more flanges. The teeth may be located on the flange, the flat portion, or both. The washer may also have one or more elongated side portions which extend downward (toward the enlarged end of the fastener when assembled). The side portion(s) may be located on the same side of the flange(s).
- Another embodiment is an assembly that comprises a fastener and a washer used to clamp at least three metallic objects. The fastener comprises an enlarged end with at least one raised portion and a shank. The washer comprises multiple raised portions and an opening. When installed, the raised portions of the fastener penetrate the first object, at least one raised portion of the washer penetrates the second object, and at least one raised portion of the washer penetrates the third object. The assembly provides one or more grounding paths from one object to another.
- Additionally, the washer in this embodiment may have at least one elongated side portion which extends downward (toward the enlarged end of the fastener when assembled). The side portion may be located on the same side of a flange if the washer also has one or more flanges. The side portion may be used to separate objects that are contacted by the washer.
- For example, an assembly with a metallic t-bolt with a shank and a head that has teeth and a metallic washer with an opening and teeth may be used to couple two metallic solar panel frames and a metallic rail. An electrical grounding path from the rail to a solar panel frame is formed when the teeth of the t-bolt penetrate into the surfaces of the rail and the teeth of the washer penetrate one of the solar panel frames. Similarly, the assembly can create a grounding path between the panel frames when the teeth of the washer penetrate both the solar panel frames.
- Similarly, an embodiment may be used to clamp two or more objects with the raised portions of the fastener and the raised portion of the washer contact the same objects. Therefore, there are at least two grounding path between two affixed objects—one from the first object through the washer alone to the second object, and the other from the first object through the washer and the fastener and finally to the second object. An example is when the assembly is used to clamp two metallic solar panel rails and provide grounding path between them, without the metallic rail at the bottom.
- This invention may also contain a method for affixing a metallic object to another metallic object. An exemplary method may comprise steps of using one of the aforementioned assemblies to clamp two or more objects and thus may create at least an electrical grounding path between the objects.
- A person with ordinary skill in the relevant art would know that any shape or size of the fastener or the washer may be adopted as long as the assembly can be used to clamp two or more objects and provide a grounding path. Any combinations of suitable number, shape, and size of raised portions of the fastener and the washer may be used. Also, any materials suitable to achieve the object of the current invention may be chosen, such as stainless steel or metallic materials.
