ABSTRACT:

FIELD OF THE INVENTION
The present invention relates, in general, to augers and in particular, to augers which are used for securing objects in a material such as sand. Specifically, an auger is described which may be readily manufactured in a material such as plastic.
BACKGROUND OF THE INVENTION
When going to a location such as a beach, it is often customary to bring along an umbrella for shade. In the prior art, such an umbrella included a pointed shaft. The pointed shaft was inserted into the sand. The user of the umbrella would attempt to push the umbrella as deeply as possible into the sand to prevent the umbrella from being knocked out of the sand by a strong gust of wind.
Unfortunately, such attempts to maintain the umbrella in place have not been successful. Specifically, it is known to experience a strong gust of wind which knocks the umbrella out of place. As a result, the umbrella may be flung along the beach, causing a potential safety hazard.
In an attempt to rectify this problem, various augers have been developed. An exemplary auger is illustrated, for example, in U.S. Pat. No. 5,046,699 (Perreault et al.). As disclosed, the auger includes a first end with a screw thread at a first end of a shaft. A second end of the shaft includes an opening. A plurality of handles extend perpendicularly from the shaft and near the opening. In operation, the thread member is held against the sand and the handles are rotated, thus causing the auger to be screwed into the sand. After the auger has been screwed into the sand, a beach umbrella may be inserted into the opening. In this manner, the end of the beach umbrella is able to extend a considerable distance below the top surface of the sand.
SUMMARY OF THE INVENTION
An auger is produced from a material such as plastic. The auger includes a shaft with a first pointed end having a thread member thereon. A second end of the auger includes an opening. Handles extend perpendicularly from the shaft and near the opening. The threads are formed in a manner to facilitate removal of the auger from a mold in which the auger may be formed using a plastic-type material. On opposite ends of the shaft, the thickness of the thread is increased to provide a clearance for the thread so that the completed auger may be readily removed from the mold.
