ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to laser sighter and more particularly pertains to a new laser sighting device for improving the overall targeting accuracy of the gun.
2. Description of the Prior Art
The use of laser sighter is known in the prior art. More specifically, laser sighter 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. 5,787,631 U.S. Pat. No. 4,164,081; U.S. Pat. No. 5,741,185; U.S. Pat. No. 3,782,832; U.S. Pat. No. 4,530,162; and U.S. Pat. No. 4,825,258.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new laser sighting device. The inventive device includes a casing having an open front end, an open back end, a side wall, a first flange member being securely disposed upon and extending from the interior of the side wall intermediate of the ends, a second flange member being securely disposed upon and extending from the interior of the side wall at the back end thereof, and also includes a laser light which includes a body member having a laser diode at a front end and a contact pole at the back end thereof with the body member being engaged in the casing at the open front end, and also includes a contact switch member having housing, a front wall, a side wall, and open back end which is closeable with a cap member, a flange member securely disposed about the exterior of the side wall, and a flanged portion near the back end of the housing, and further includes a spring mounted about the contact switch member and three batteries removeably disposed within the housing for energizing the laser light.
In these respects, the laser sighting device 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 improving the overall targeting accuracy of the gun.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of laser sighter now present in the prior art, the present invention provides a new laser sighting device construction wherein the same can be utilized for improving the overall targeting accuracy of the gun.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new laser sighting device apparatus and method which has many of the advantages of the laser sighter mentioned heretofore and many novel features that result in a new laser sighting device which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art laser sighter, either alone or in any combination thereof.
To attain this, the present invention generally comprises a casing having an open front end, an open back end, a side wall, a first flange member being securely disposed upon and extending from the interior of the side wall intermediate of the ends, a second flange member being securely disposed upon and extending from the interior of the side wall at the back end thereof, and also includes a laser light which includes a body member having a laser diode at a front end and a contact pole at the back end thereof with the body member being engaged in the casing at the open front end, and also includes a contact switch member having housing, a front wall, a side wall, and open back end which is closeable with a cap member, a flange member securely disposed about the exterior of the side wall, and a flanged portion near the back end of the housing, and further includes a spring mounted about the contact switch member and three batteries removeably disposed within the housing for energizing the laser light.
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 laser sighting device apparatus and method which has many of the advantages of the laser sighter mentioned heretofore and many novel features that result in a new laser sighting device which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art laser sighter, either alone or in any combination thereof.
It is another object of the present invention to provide a new laser sighting device which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new laser sighting device which is of a durable and reliable construction.
An even further object of the present invention is to provide a new laser sighting device 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 laser sighting device economically available to the buying public.
Still yet another object of the present invention is to provide a new laser sighting device 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 laser sighting device for improving the overall targeting accuracy of the gun.
Yet another object of the present invention is to provide a new laser sighting device which includes a casing having an open front end, an open back end, a side wall, a first flange member being securely disposed upon and extending from the interior of the side wall intermediate of the ends, a second flange member being securely disposed upon and extending from the interior of the side wall at the back end thereof, and also includes a laser light which includes a body member having a laser diode at a front end and a contact pole at the back end thereof with the body member being engaged in the casing at the open front end, and also includes a co
