ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an adjustable snow plow shovel and more particularly pertains to allowing easy removal of snow from sidewalks and driveways through the use of adjusting the angle of snow blades and pushing rather than lifting and throwing, so as to reduce back strain common to shoveling. The operator can lean into it and keep going.
The use of snow removal devices is known in the prior art. More specifically, snow removal devices heretofore devised and utilized for the purpose of removing snow 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. 5,511,328 to Fingerer discloses an adjustable hand operated snow plow capable of positioning a pair of blades in a variety of angular configurations. U.S. Pat. No. 1,049,812 to Darling discloses a combination snow plow and shovel constructed of two blades attached to a diamond shaped frame. U.S. Pat. No. 5,472,252 to Barone discloses a snow shovel with an adjustable handle.
While these devices fulfill their respective, particular objective and requirements, the aforementioned patents do not describe an adjustable snow plow shovel for allowing easy removal of snow from sidewalks and driveways.
In this respect, the adjustable snow plow shovel 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 allowing easy removal of snow from sidewalks and driveways with less effort and back strain.
Therefore, it can be appreciated that there exists a continuing need for a new and improved adjustable snow plow shovel which can be used for allowing easy removal of snow from sidewalks and driveways. 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 snow removal devices now present in the prior art, the present invention provides an improved adjustable snow plow shovel. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved adjustable snow plow shovel which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a T-shaped handle comprised of a horizontal gripping member and an elongated vertical shaft member. The horizontal gripping member has opposed ends and a midpoint. The elongated vertical shaft member has an upper end and a lower end. The upper end is secured to the midpoint of the horizontal gripping member. The upper end has a pair of supports secured thereto and secured to the horizontal gripping member. The lower end has a pair of support brackets extending outwardly therefrom in opposite directions. The support brackets each have an angularly disposed outer end having an aperture therethrough. A pair of plow blades are pivotally coupled with a plow blade support which is secured to the lower end of the elongated vertical shaft member of the T-shaped handle. Each of the plow blades has an inner edge and an outer edge. The inner edge is coupled to the lower end of the elongated vertical shaft member by a piano hinge. Each of the plow blades has a plurality of linearly aligned apertures therethrough on a horizontal plane in a spaced relationship. The apertures are selectively alignable with the apertures of the outer ends of the support brackets of the T-shaped handle for receiving a bolt therethrough that couples with a wing nut.
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 adjustable snow plow shovel which has all the advantages of the prior art snow removal devices and none of the disadvantages.
It is another object of the present invention to provide a new and improved adjustable snow plow shovel which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new and improved adjustable snow plow shovel which is of durable and reliable construction.
An even further object of the present invention is to provide a new and improved adjustable snow plow shovel 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 an adjustable snow plow shovel economically available to the buying public.
Even still another object of the present invention is to provide a new and improved adjustable snow plow shovel for allowing easy removal of snow from sidewalks and driveways.
Lastly, it is an object of the present invention to provide a new and improved adjustable snow plow shovel including a T-shaped handle comprised of a horizontal gripping member and an elongated vertical shaft member. The horizontal gripping member has opposed ends and a midpoint. The elongated vertical shaft member has an upper end and a lower end. The upper end is secured to the midpoint of the horizontal gripping member. The lower end has a pair of support brackets extending outwardly therefrom in opposite directions. The support brackets each have an angularly disposed outer end having an aperture therethrough. A pair of plow blades are pivotally coupled with a plow blade support which is secured to the lower end of the elongated vertical shaft member of the T-shaped handle. Each of the plow blades has a plurality of linearly aligned apertures therethrough on a horizontal plane in a spaced relationship. The apertures are selectively alignable with the apertures of the outer ends of the support brackets of the T-shaped handle for receiving a bolt therethrough that couples with a wing nut.
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.
