In general, the present disclosure relates to an article of manufacture providing a self-installing hammer drill SDS-based grounding rod according to the present invention. To better understand the present invention,
The shaft member 101 also comprises a set of case-hardened flanges 104a-d about the circumference of the lower end 103 of the shaft member 101. The set of case-hardened flanges 104a-d assists the grounding rod 100 in cutting through rocks and dirt of the ground material as the grounding rod 100 spins in the hammer drill. In a preferred embodiment, the case-hardened flanges 104a-d may comprise 2 flanges, although additional flanges may be used. The shaft member 101 is sized to fit within a ¾″ drive of a hammer drill. The top of the ground rod 100 uses a slotted drive shaft (SDS) end for a bit retention system in one embodiment. Once installed into the ground material, an electrical connection may be coupled to the grounding rod 100 as needed.
About a top end 105 of the shaft member 101, a pair of SDS-style slots 102 is cut into the shaft member 101 for coupling to a hammer drill SD S-style (not shown). The top end 105 of the shaft member 101 is inserted into the hammer drill SDS tool holder and coupled to its chuck.
In an alternate embodiment, an optional top head 205 may be coupled to the top end 105 of the shaft member 101. The optional top head 205 adds spline drill shank 202a-c about the circumference of the shaft member 101. The spline drill shank 202a-c couples the grounding rod 100 within a spline bit chuck (not shown).
Once secure within the chuck, the grounding rod 100 may be installed into the ground in a rotating fashion ordinarily using the SDS-style hammer drill. The case-hardened tip 201 and the corresponding case-hardened flanges 104a-d cut into ground material permitting the grounding rod 100 to be inserted into the rocks and dirt of the ground surface. The case-hardened flanges 104a-d may include masonry drill bit characteristics to aid in the insertion of the grounding rod 100 into the ground materials. For example, the grounding rod may be made from common ground rods material consisting of galvanized, copper and come in lengths of 6, 8, and 10 feet.
Even though particular combinations of features are recited in the present application, these combinations are not intended to limit the disclosure of the invention. In fact, many of these features may be combined in ways not specifically recited in this application. In other words, any of the features mentioned in this application may be included in this new invention in any combination or combinations to allow the functionality required for the desired operations.
No element, act, or instruction used in the present application should be construed as critical or essential to the invention unless explicitly described as such. Further, the phrase “based on” is intended to mean “based, at least in part, on” unless explicitly stated otherwise.
