Benefits of technology
The invention provides a ground-hole forming apparatus that includes a drivable element and a bulb with resilient portions. The driving element is movable in first and second directions to impact the resilient portions of the bulb and drive the apparatus in the same directions. The resilient portions absorb and deaden the impacts to reduce noise and impact. The apparatus can be used to create ground holes with reduced noise and impact.
Problems solved by technology
The impacts between the hammering device and the end of the rod generate a substantial amount of noise.

Embodiment Construction
[0015]As will be described below with reference to FIGS. 1-3, a ground-hole forming apparatus 10 is provided and may be used in the formation of ground-holes in the ground at bore-holes that are already formed in asphalt and / or concrete. The ground-hole forming apparatus 10 is provided with resilient portions that absorb and deaden sounds generated by impacts between various components of the ground-hole forming apparatus 10 so that the generated sounds may be limited to less than about 73 dBA.
[0016]With reference to FIGS. 1 and 2, the ground-hole forming apparatus 10 is provided and includes a first elongate member 20, a second elongate member 30 and a bulb 40. The first elongate member 20 includes a tubular element 21 that has a compliant outer surface, which is appropriate for being gripped and manipulated by an operator. The tubular element 21 is formed to define an interior 22. The interior 22 has a first end 221 and second end 222, which is opposite the first end 221. The firs...

Abstract
A ground-hole forming apparatus is provided and includes a drivable element, a bulb coupled to an end of the drivable element and including first and second resilient portions, a driving element including first and second ends and being movable by an operator in first and second directions such that the first and second ends drivably impact the first and second resilient portions of the bulb, respectively, to thereby drive the drivable element in the first and second directions, respectively. The first and second resilient portions are configured to absorb and deaden respective impacts thereof with the first and second ends.
Description
BACKGROUND OF THE INVENTION[0001]The subject matter disclosed herein relates to a ground-hole forming device and, more particularly, to a ground-hole forming device that muffles sound.[0002]In gas detecting operations, it is often necessary to dig holes at various places in the ground near where a leak is suspected to have occurred. Once the hole is formed and dug out, a gas detecting monitor is placed nearby and identifies whether a leak is present or not by determining levels of gases in the surrounding atmosphere. Generally, the hole is formed by an initial boring of a hole through asphalt and / or concrete and then forcing a long rod into the ground at the hole. The latter step is done by placing an end of the rod into the hole and hitting the other end with a hammering device.[0003]The impacts between the hammering device and the end of the rod generate a substantial amount of noise. Indeed, in some cases, the sounds generated by the impacts can be above a desired threshold.BRIEF...
