ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to ratchet wrenches and more particularly pertains to a new detachable handle socket ratchet wrench system for permitting a user to change handles to suit the needs of the user.
2. Description of the Prior Art
The use of ratchet wrenches is known in the prior art. More specifically, ratchet wrenches 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. 5,685,208 by Tidwell; U.S. Pat. No. 4,829,857 by Jones; U.S. Pat. No. 5,193,419 by Lee; U.S. Pat. No. 5,109,737 by Raber; U.S. Pat. No. 2,263,508 by Lee; and U.S. Pat. No. Des. 336,225 by Lin.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new detachable handle socket ratchet wrench system. The inventive device includes a ratchet head with a tubular sleeve outwardly extending therefrom defining a receptacle. A plurality of elongate handles are provided each having an insertion portion adjacent a distal end of the respective handle. The insertion portion of each of the handles is insertable into the receptacle of the sleeve. Each of the handle has a length defined between the proximal and distal ends of the respective handle. The length of a first of the handles is greater than the length of a second of the handles and at least two times greater than the length of a third of the handles. The length of the third handle is greater than about one-half the length of the second handle and less than about four-fifths the length of the second handle.
In these respects, the detachable handle socket ratchet wrench system 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 permitting a user to change handles to suit the needs of the user.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of ratchet wrenches now present in the prior art, the present invention provides a new detachable handle socket ratchet wrench system construction wherein the same can be utilized for permitting a user to change handles to suit the needs of the user.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new detachable handle socket ratchet wrench system apparatus and method which has many of the advantages of the ratchet wrenches mentioned heretofore and many novel features that result in a new detachable handle socket ratchet wrench system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art ratchet wrenches, either alone or in any combination thereof.
To attain this, the present invention generally comprises a ratchet head with a tubular sleeve outwardly extending therefrom defining a receptacle. A plurality of elongate handles are provided each having an insertion portion adjacent a distal end of the respective handle. The insertion portion of each of the handles is insertable into the receptacle of the sleeve. Each of the handle has a length defined between the proximal and distal ends of the respective handle. The length of a first of the handles is greater than the length of a second of the handles and at least two times greater than the length of a third of the handles. The length of the third handle is greater than about one-half the length of the second handle and less than about four-fifths the length of the second handle.
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 detachable handle socket ratchet wrench system apparatus and method which has many of the advantages of the ratchet wrenches mentioned heretofore and many novel features that result in a new detachable handle socket ratchet wrench system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art ratchet wrenches, either alone or in any combination thereof.
It is another object of the present invention to provide a new detachable handle socket ratchet. wrench system which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new detachable handle socket ratchet wrench system which is of a durable and reliable construction.
An even further object of the present invention is to provide a new detachable handle socket ratchet wrench system 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 detachable handle socket ratchet wrench system economically available to the buying public.
Still yet another object of the present invention is to provide a new detachable handle socket ratchet wrench system 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 detachable handle socket ratchet wrench system for permitting a user to change handles to suit the needs of the user.
Yet another object of the present invention is to provide a new detachable handle socket ratchet wrench system which includes a ratchet head with a tubular sleeve outwardly extending therefrom defining a receptacle. A plurality of elongate handles are provided each having an insertion portion adjacent a distal end of the respective handle. The insertion portion of each of the handles is insertable into the receptacle of the sleeve. Each of the handle has a length defined between the proximal and distal ends of the respective handle. The length of a first of the handles is greater than the length of a seco
