ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a ratchet wrench assembly with gripping surface and more particularly pertains to preventing slippage during any type of handling of a ratchet wrench.
2. Description of the Prior Art
The use of gripping surfaces for ratchet wrench handles is known in the prior art. More specifically, gripping surfaces for ratchet wrench handles heretofore devised and utilized for the purpose of preventing slippage during use of a ratchet wrench 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.
By way of example, the prior art includes U.S. Pat. Nos. 4,942,791; 5,329,834; U.S. Patent Des. 360,123; U.S. Pat. Nos. 4,030,150; 5,280,735; and 5,343,776.
In this respect, the ratchet wrench assembly with gripping surface 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 preventing slippage during any type of handling of a ratchet wrench.
Therefore, it can be appreciated that there exists a continuing need for a new and improved ratchet wrench assembly with gripping surface which can be used for preventing slippage during any type of handling of a ratchet wrench. In this regard, the present invention substantially fulfills this need.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of gripping surfaces for ratchet wrench handles now present in the prior art, the present invention provides an improved ratchet wrench assembly with gripping surface. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved ratchet wrench assembly with gripping surface which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a ratchet wrench with a first end extent having a cylindrical configuration, a first diameter and an outer surface. An intermediate extent is integrally coupled to the first end extent in coaxial alignment therewith. The intermediate extent is equipped with a cylindrical configuration having a second diameter less than the first diameter and an outer surface. Finally, a second end extent is provided having a disk-shaped head with a top circular face, a bottom circular face, and a periphery formed therebetween with an outer surface. As shown in
FIG. 1
, the periphery of the head is integrally coupled to the intermediate extent. It should be noted that the head has a cubical rotator rotatably coupled to the top face thereof. With reference to
FIG. 3
, there is shown a ratchet wrench extender including a first end extent with a cylindrical configuration having a first diameter and an outer surface. The first end extent has a cubical male connector integrally coupled thereto for reasons that will become apparent hereinafter. An intermediate extent is integrally coupled to the first end extent in coaxial alignment therewith. The intermediate extent has a cylindrical configuration having a second diameter less than the first diameter and an outer surface. A second end extent also is equipped with a cylindrical configuration having the first diameter and an outer surface. A cubical female receptor is formed in the second end extent for releasably receiving the cubical rotator.
FIG. 2
shows a cylindrical socket having a first circular end face with a cubical female receptor formed therein for releasably receiving the male cubical rotator and the male connector. The socket further has a second circular end face with a hexagonal female receptor. A periphery is formed between the end faces with an outer surface. It is imperative that every outer surface of the ratchet wrench, ratchet wrench extender, and the socket have a plurality of intersecting, continuous and linear grooves formed therein. Such grooves are formed in the outer surfaces over an entirety thereof. As shown in
FIG. 4
, each groove has a triangular cross-section and a common predetermined depth. The grooves are configured to define a multiplicity of uniform identical parallelograms to preclude slippage.
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, of course, 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.
It is therefore an object of the present invention to provide a new and improved ratchet wrench assembly with gripping surface which has all the advantages of the prior art gripping surfaces for ratchet wrench handles and none of the disadvantages.
It is another object of the present invention to provide a new and improved ratchet wrench assembly with gripping surface which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new and improved ratchet wrench assembly with gripping surface which is of a durable and reliable construction.
An even further object of the present invention is to provide a new and improved ratchet wrench assembly with gripping surface 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 ratchet wrench assembly with gripping surface economically available to the buying public.
Still yet another object of the present invention is to provide a new and improved ratchet wrench assembly with gripping surface 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 prevent slippage during any type of handling of a ratchet wrench.
Lastly, it is an object of the present invention to provide a new and improved ratchet wrench assembly with gripping surface including a ratchet wrench having a plurality of extents each with an outer surface. Every outer surface of the ratchet wrench has a gripping surface formed along its entirety.
These together with other objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be had to the accompanying drawings and descriptive matter in which there is illustrated preferred embodiments of the inve
