ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a dead-bolt gripper and more particularly pertains to a new dead-bolt locking device for preventing a dead-bolt lock from being picked open.
2. Description of the Prior Art
The use of dead-bolt gripper is known in the prior art. More specifically, dead-bolt gripper 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. 4,673,202; U.S. Pat. No. 5,313,812; U.S. Pat. No. 4,127,967; U.S. Pat. No. 5,193,373; U.S. Pat. No. 3,263,462; and U.S. Pat. No. Des. 317,556.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new dead-bolt locking device. The inventive device includes a generally rectangular support member having a back side, a front side, a front end, and a back end, and also having a track disposed in the front side and extending through the front end and terminating near the back end; and also includes a locking member having a back side, a front side, a front end, a slot extending through the front end and being adapted to receive the handle of the dead-bolt lock, and a boss integrally attached to the back side and being slidably received in the track; and further includes a handle member integrally attached to the front side of the locking member.
In these respects, the dead-bolt locking 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 preventing a dead-bolt lock from being picked open.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of dead-bolt gripper now present in the prior art, the present invention provides a new dead-bolt locking device construction wherein the same can be utilized for preventing a dead-bolt lock from being picked open.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new dead-bolt locking device which has many of the advantages of the dead-bolt gripper mentioned heretofore and many novel features that result in a new dead-bolt locking device which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art dead-bolt gripper, either alone or in any combination thereof.
To attain this, the present invention generally comprises a generally rectangular support member having a back side, a front side, a front end, and a back end, and also having a track disposed in the front side and extending through the front end and terminating near the back end; and also includes a locking member having a back side, a front side, a front end, a slot extending through the front end and being adapted to receive the handle of the dead-bolt lock, and a boss integrally attached to the back side and being slidably received in the track; and further includes a handle member integrally attached to the front side of the locking member.
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 dead-bolt locking device which has many of the advantages of the dead-bolt gripper mentioned heretofore and many novel features that result in a new dead-bolt locking device which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art dead-bolt gripper, either alone or in any combination thereof.
It is another object of the present invention to provide a new dead-bolt locking device which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new dead-bolt locking device which is of a durable and reliable construction.
An even further object of the present invention is to provide a new dead-bolt locking 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 dead-bolt locking device economically available to the buying public.
Still yet another object of the present invention is to provide a new dead-bolt locking 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 dead-bolt locking device for preventing a dead-bolt lock from being picked open.
Yet another object of the present invention is to provide a new dead-bolt locking device which includes a generally rectangular support member having a back side, a front side, a front end, and a back end, and also having a track disposed in the front side and extending through the front end and terminating near the back end; and also includes a locking member having a back side, a front side, a front end, a slot extending through the front end and being adapted to receive the handle of the dead-bolt lock, and a boss integrally attached to the back side and being slidably received in the track; and further includes a handle member integrally attached to the front side of the locking member.
Still yet another object of the present invention is to provide a new dead-bolt locking device that can be easily and conveniently mounted to any door.
Even still another object of the present invention is to provide a new dead-bolt locking device that prevents the door from being opened from the outside even with a duplicate key.
