ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to tools and more particularly pertains to a new adjustable hinge adjustment tool for adjusting variable sized hinges.
2. Description of the Prior Art
The use of tools is known in the prior art. More specifically, tools 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. 5,435,030; U.S. Pat. No. 5,305,667; U.S. Pat. No. 5,595,098; U.S. Pat. No. 4,555,929; U.S. Pat. No. 3,332,274; and U.S. Pat. No. 3,965,720; U.S. Pat. Des. No. 113,665.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new adjustable hinge adjustment tool. The inventive device includes a handle portion and a wrench head portion. The handle portion is an elongate member having a distal end and a proximal end, wherein the proximal end is fixedly coupled to the head portion. The head portion comprises a first portion and a second portion. The first portion is fixedly coupled to the proximal end of the handle portion. A notch for receiving, a drive worm screw is in the first portion of the head portion. The second portion of the wrench comprises a base, a fixed jaw and a movable jaw. The base is fixedly coupled to the first portion of the head portion. The fixed jaw is fixedly coupled to the base and extends away from the handle. A guide slot in the base defines a track for the movable jaw. The guide slot extends into the notch. The movable jaw has a bottom member thereon adapted to be inserted into the guide slot. The bottom member of the movable jaw has V-shaped recesses therein. The drive worm screw is rotatably mounted in the notch and has a width larger than a depth of the notch such that a peripheral edge of the drive worm screw extends into the slot. The V-shaped recesses are directed toward and are in contact with the drive worm screw. The fixed jaw and the adjustable jaw have concave inner surfaces such that when the adjustable jaw is brought to a location generally adjacent to the fixed jaw, a generally annular bore is defined.
In these respects, the adjustable hinge adjustment tool 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 adjusting variable sized hinges.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of tools now present in the prior art, the present invention provides a new adjustable hinge adjustment tool construction wherein the same can be utilized for adjusting variable sized hinges.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new adjustable hinge adjustment tool apparatus and method which has many of the advantages of the tools mentioned heretofore and many novel features that result in a new adjustable hinge adjustment tool which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art tools, either alone or in any combination thereof.
To attain this, the present invention generally comprises a handle portion and a wrench head portion. The handle portion is an elongate member having a distal end and a proximal end, wherein the proximal end is fixedly coupled to the head portion. The head portion comprises a first portion and a second portion. The first portion is fixedly coupled to the proximal end of the handle portion. A notch for receiving a drive worm screw is in the first portion of the head portion. The second portion of the wrench comprises a base, a fixed jaw and a movable jaw. The base is fixedly coupled to the first portion of the head portion. The fixed jaw is fixedly coupled to the base and extends away from the handle. A guide slot in the base defines a track for the movable jaw. The guide slot extends into the notch. The movable jaw has a bottom member thereon adapted to be inserted into the guide slot. The bottom member of the movable jaw has V-shaped recesses therein. The drive worm screw is rotatably mounted in the notch and has a width larger than a depth of the notch such that a peripheral edge of the drive worm screw extends into the slot. The V-shaped recesses are directed toward and are in contact with the drive worm screw. The fixed jaw and the adjustable jaw have concave inner surfaces such that when the adjustable jaw is brought to a location generally adjacent to the fixed jaw, a generally annular bore is defined.
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 adjustable hinge adjustment tool apparatus and method which has many of the advantages of the tools mentioned heretofore and many novel features that result in a new adjustable hinge adjustment tool which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art tools, either alone or in any combination thereof.
It is another object of the present invention to provide a new adjustable hinge adjustment tool which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new adjustable hinge adjustment tool which is of a durable and reliable construction.
An even further object of the present invention is to provide a new adjustable hinge adjustment tool 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 adjustable hinge adjustment tool economically available to the buying public.
Still yet another object of the present invention is to provide a new adjustable hinge adjustment tool which provides in the apparatuses and methods of the prior art some of the advantages thereof, while si
