ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a tool with a heated handle and more particularly pertains to making the wielding of a tool easier in cold weather.
The use of heated handle devices is known in the prior art. More specifically, heated handle devices heretofore devised and utilized for the purpose of heating a handle 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, U.S. Pat. No. 4,584,787 to Aho discloses a heated handle comprised of an inner cylindrical container for holding a fuel stick, for use with a fishing rod. U.S. Pat. No. 4,654,970 to Nagashima discloses a heated handle for a power driven chain saw. U.S. Pat. No. Des. 367,657 to Sayles discloses an ornamental design for a heated handle for a snow blower. U.S. Pat. No. 5,276,310 to Schmidt discloses an electrically heated toolbox.
While these devices fulfill their respective, particular objective and requirements, the aforementioned patents do not describe a tool with a heated handle for making the wielding of a tool easier in cold weather.
In this respect, the tool with a heated handle according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of making the wielding of a tool easier in cold weather.
Therefore, it can be appreciated that there exists a continuing need for a new and improved tool with a heated handle which can be used for making the wielding of a tool easier in cold weather. In this regard, the present invention substantially fulfills this need.
SUMMARY OF THE INVENTION
In the view of the foregoing disadvantages inherent in the known types of heated handle devices now present in the prior art, the present invention provides an improved tool with a heated handle. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved tool with a heated handle which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a tool head having a downwardly extending stem portion. An upper handle portion is provided having an upper end and a lower end. The upper end is secured to the downwardly extending stem portion of the tool head. The upper handle portion is of solid construction. A lower handle portion is provided having an upper end secured to the lower end of the upper handle portion. The lower handle portion has an open lower end and a hollow interior. The lower handle portion has a plurality of apertures therein exposing the hollow interior. The open lower end has an end cap hingedly coupled thereto. A heat cartridge is provided that is dimensioned for being received within the hollow interior of the lower handle portion. The heat cartridge is defined by a flexible central tube having a pair of enlarged rigid end caps. A lowermost end cap has a handle secured thereto. The central tube has a mixture of sodium acetate and water therein. The central tube has a flexible metal wire disposed therein whereby flexing of the metal wire will activate the mixture to provide heat.
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 tool with a heated handle which has all the advantages of the prior art heated handle devices and none of the disadvantages.
It is another object of the present invention to provide a new and improved tool with a heated handle which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new and improved tool with a heated handle which is of durable and reliable construction.
An even further object of the present invention is to provide a new and improved tool with a heated handle 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 a tool with a heated handle economically available to the buying public.
Even still another object of the present invention is to provide a new and improved tool with a heated handle for making the wielding of a tool easier in cold weather.
Lastly, it is an object of the present invention to provide a new and improved tool with a heated handle including a tool head having a downwardly extending stem portion. An upper handle portion is provided having an upper end and a lower end. The upper end is secured to the downwardly extending stem portion of the tool head. A lower handle portion is provided having an upper end secured to the lower end of the upper handle portion. The lower handle portion has an open lower end and a hollow interior. The lower handle portion has a plurality of apertures therein exposing the hollow interior. The open lower end has an end cap hingedly coupled thereto. A heat cartridge is provided that is dimensioned for being received within the hollow interior of the lower handle portion.
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 invention.
