ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to post removal devices and more particularly pertains to a new post removal device for removing fence posts having lugs thereon.
2. Description of the Prior Art
The use of post removal devices is known in the prior art. More specifically, post removal devices 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. Nos. 5,681,030; 2,926,890; 2,777,726; 5,499,795; 654,001; and U.S. Des. Pat. No. 337,412.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new post removal device. The inventive device includes an elongated member having a first end and a second end. The elongated member has middle portion, a first wall and a second wall such that the elongated member generally has U-shaped cross-section taken traverse to a longitudinal axis of the elongated member. A plate is attached to the first end of the elongated member. The plate lies in a plane orientated generally perpendicular to the longitudinal axis of the plate. A catch is attached to the elongated member and is positioned nearer the second end than the first end. The catch comprises a panel having a first edge, a second edge, a third edge and a fourth edge. The first edge is integrally attached to the middle portion and each of the second and third edges is attached to one of the first and second walls. The panel is in an angular relationship with the middle portion such that the panel generally extends toward the second end of the elongate member. The post is positioned between the first and second walls such that the catch may engage one of the lugs.
In these respects, the post removal device 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 removing fence posts having lugs thereon.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of post removal devices now present in the prior art, the present invention provides a new post removal device construction wherein the same can be utilized for removing fence posts having lugs thereon.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new post removal device apparatus and method which has many of the advantages of the post removal devices mentioned heretofore and many novel features that result in a new post removal device which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art post removal devices, either alone or in any combination thereof.
To attain this, the present invention generally comprises an elongated member having a first end and a second end. The elongated member has middle portion, a first wall and a second wall such that the elongated member generally has U-shaped cross-section taken traverse to a longitudinal axis of the elongated member. A plate is attached to the first end of the elongated member. The plate lies in a plane orientated generally perpendicular to the longitudinal axis of the plate. A catch is attached to the elongated member and is positioned nearer the second end than the first end. The catch comprises a panel having a first edge, a second edge, a third edge and a fourth edge. The first edge is integrally attached to the middle portion and each of the second and third edges is attached to one of the first and second walls. The panel is in an angular relationship with the middle portion such that the panel generally extends toward the second end of the elongate member. The post is positioned between the first and second walls such that the catch may engage one of the lugs.
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 removal device apparatus and method which has many of the advantages of the post removal devices mentioned heretofore and many novel features that result in a new post removal device which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art post removal devices, either alone or in any combination thereof.
It is another object of the present invention to provide a new post removal device which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new post removal device which is of a durable and reliable construction.
An even further object of the present invention is to provide a new post removal device 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 removal device economically available to the buying public.
Still yet another object of the present invention is to provide a new post removal device 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 removal device for removing fence posts having lugs thereon.
Yet another object of the present invention is to provide a new post removal device which includes an elongated member having a first end and a second end. The elongated member has middle portion, a first wall and a second wall such that the elongated member generally has U-shaped cross-section taken traverse to a longitudinal axis of the elongated member. A plate is attached to the first end of the elongated member. The plate lies in a plane orientated generally perpendicular to the longitudinal axis of the plate. A catch is attached to the elongated member and is positioned nearer
