ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to post hole diggers and more particularly pertains to a new post hole digger for allowing a user to dig a posthole with minimized physical effort.
2. Description of the Prior Art
The use of posthole diggers is known in the prior art. More specifically, posthole diggers heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art, which have been developed for the fulfillment of countless objectives and requirements.
Known prior art includes U.S. Pat. No. 5,669,648; U.S. Pat. No. 5,320,363; U.S. Pat. No. 5,743,579; U.S. Pat,. No. 4,042,270; U.S. Pat. No. Des. 311,853; and U.S. Pat. No. 2,654,626.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new post hole digger. The inventive device includes a digging assembly that has a pair of spade portions. The spade portions are adapted for being forced into dirt and closing together to collect some of the dirt for removal by the user. A handle is coupled to the digging assembly such that the handle is adapted to be held by the user for forcing the digging assembly in the dirt. An actuating member is coupled to the digging assembly. The actuating member is for actuating the digging assembly such that the actuating member is for closing and opening of the spade portions for collecting and releasing dirt when the digging assembly is being used to dig a post hole.
In these respects, the post hole digger according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of allowing a user to dig a posthole with minimized physical effort.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of post hole diggers now present in the prior art, the present invention provides a new post hole digger construction wherein the same can be utilized for allowing a user to dig a post hole with minimized physical effort.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new post hole digger apparatus and method which has many of the advantages of the post hole diggers mentioned heretofore and many novel features that result in a new post hole digger which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art post hole diggers, either alone or in any combination thereof.
To attain this, the present invention generally comprises a digging assembly that has a pair of spade portions. The spade portions are adapted for being forced into dirt and closing together to collect some of the dirt for removal by the user. A handle is coupled to the digging assembly such that the handle is adapted to be by the user for forcing the digging assembly in the dirt. An actuating member is coupled to the digging assembly. The actuating member is for actuating the digging assembly such that the actuating member is for closing and opening of the spade portions for collecting and releasing dirt when the digging assembly is being used to dig a post hole.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application. The abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
It is therefore an object of the present invention to provide a new post hole digger apparatus and method which has many of the advantages of the post hole diggers mentioned heretofore and many novel features that result in a new post hole digger which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art post hole diggers, either alone or in any combination thereof.
It is another object of the present invention to provide a new post hole digger, which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new post hole digger, which is of a durable and reliable construction.
An even further object of the present invention is to provide a new post hole digger which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such post hole digger economically available to the buying public.
Still yet another object of the present invention is to provide a new post hole digger, which provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith.
Still another object of the present invention is to provide a new post hole digger for allowing a user to dig a posthole with minimized physical effort.
Yet another object of the present invention is to provide a new post hole digger, which includes a digging assembly that has a pair of spade portions. The spade portions are adapted for being forced into dirt and closing together to collect some of the dirt for removal by the user. A handle is coupled to the digging assembly such that the handle is adapted to be held by the user for forcing the digging assembly in the dirt. An actuating member is coupled to the digging assembly. The actuating member is for actuating the digging assembly such that the actuating member is for closing and opening of the spade portions for collecting and releasing dirt when the digging assembly is being used to dig a post hole.
Still yet another object of the present invention is to provide a new post hole digger that would be its ease of use, convenience, reduction of labor and physical strain, and cost-effectiveness.
Even still another object of the present invention is to provide a new post hole digger that the design of the present invention would prevent a handle from breaking, which would prevent the user from having to purchase a new posthole digger.
