Frame for pistol with removable metal rail

Abstract

The present invention relates to a frame for a pistol with a removable metal rail, in which a pistol has a slide made of a plastic material, and which is capable of preventing the gap between the slide and the rail of the frame from occurring due to thermal deformation, and separately disassembling the frame unit and the rail of the frame from each other to replace them as occasion demands.According to an aspect of the invention to achieve the object described above, there is provided a frame for a pistol with a removable metal rail, a pistol having a slide made of a reinforced plastic material, the frame including: a frame unit made of a metal material and having a handle and first and second insertion parts formed at its upper portion, the first and second insertion parts being spaced at a predetermined distance from each other; and front and rear rail blocks made of a metal material and fixedly inserted into the respective first and second insertion parts, the slide being slidably assembled to both upper sides of the front and rear rail blocks, wherein: the first insertion part has an insertion groove having a predetermined depth, the insertion groove having a fastening hole formed through both sides thereof; and the front rail block has an insertion protrusion protruding downward from its bottom surface by a predetermined length such that the insertion protrusion is inserted into the insertion groove, the insertion protrusion having a through-hole formed through both sides thereof to communicate with the fastening hole.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the priority of the Korean Patent Application NO 10-2017-0154801 filed on Nov. 20, 2017 in the 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 pistol with a removable metal rail, and more particularly, to a frame for a pistol with a removable metal rail, which is positioned at the lower portion of a slide made of reinforced plastic material, to be assembled to the 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 gu...

AI Technical Summary

Benefits of technology

The invention aims to provide a frame for a plastic pistol with a removable metal rail. The frame has a slide made of plastic, which prevents the gap between the slide and the rail from occurring due to thermal deformation. The frame can be easily disassembled and replaced as needed.

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.
