Frame for polymeric pistol with metal rail

Abstract

The present invention is to provide a frame for a polymeric pistol with a metal rail, capable of securing the structural soundness of firearms to secure an accuracy rate of bullet even in high-temperature environments, preventing the high-temperature heat generated in a barrel or the like from being transferred, as it is, to a handle of the frame, and disassembling and replacing components as occasion demands.According to an aspect of the invention to achieve the object described above, there is provided a frame for a polymeric pistol with a metal rail, a pistol having a slide, the frame including: a lower frame made of a reinforced plastic material and having a handle formed at its lower portion; and an upper frame assembled onto the lower frame while being assembled to the slide and made of a metal material, wherein: the lower frame includes a first support positioned in front of the handle to support a bottom surface of the upper frame, and a second support positioned behind the handle to support a rear surface of the upper frame; and the upper frame is assembled to the lower frame such that the bottom and rear surfaces of the upper frame are supported by the first and second supports, and the upper frame has a front rail and a rear rail that are integrally formed on its upper surface, the front and rear rails being assembled to the slide.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the priority of the Korean Patent Application NO 10-2017-0154824 filed on Nov. 20, 2017 in Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTIONField of the Invention[0002]The present invention relates to a frame for a polymeric pistol with a metal rail, and more particularly, to a frame for a polymeric pistol with a metal rail, which includes a rail made of metal to couple the frame made of a reinforced plastic material to a slide.Description of the Related Art[0003]In a glock pistol, the components thereof such as a slide, a lower gun body, and a magazine etc., which are not directly associated with the discharge of bullets, are made of light reinforced synthetic plastic materials having a stiffness similar to a metal, so that it reduces the weight of the pistol and is easy to carry.[0004]However, if the slide and the lower gun body etc. made ...

AI Technical Summary

Benefits of technology

[0016]The present invention has been made in view of the problem of the above-mentioned conventional plastic pistol, and an object thereof is to provide a frame for a polymeric pistol with a metal rail, capable of securing the structural soundness of firearms to secure an accuracy rate of bullet even in high-temperature environments, preventing the high-temperature heat generated in a barrel or the like from being transferred, as it is, to a handle of the frame, and disassembling and replacing components as occasion demands.

Problems solved by technology

However, if the slide and the lower gun body etc. made of the reinforced synthetic plastic materials are kept at a higher temperature for a long time, as though it has an excellent stiffness plastic, the shapes thereof are deformed more or less and gaps between the assembled internal parts are generated.

In particular, the thermal deformation of the lower gun body made of plastic materials causes malfunctions and functionality failures between various components assembled to the lower gun body.

As a result, it can deteriorate the shooting accuracy of the gun and the operation reliability thereof.

Also, since it can cause the shooting accident etc. owing to the unnecessary gaps between the components, the safety of using the gun can be also deteriorated.

However, since the metal insert disclosed in the above patent literatures is manufactured by pressing and bending a thin sheet, it is not easy to manufacture the component having a fine machining tolerance owing to the manufacturing characteristic thereof.

Therefore, since the gap between the lower gun body (gun body frame) and the metal insert is generated, the vibration and the noise are generated during firing of the bullet, thereby deteriorating the shooting accuracy thereof due to the vibration.

In this case, when the bullets are continuously fired or it is used in a high temperature environment, since a high-temperature heat is transmitted to the gripping portion for gripping the pistol by means of the user, it has trouble in using the pistol.
