Abstract

A method and apparatus providing for a buffer for the movement of pistol slide against the frame. Wherein said buffer system minimally diminishes the rebound of said pistol slide such that the pistol is still functional with respect to proper blowback operation. Wherein said buffer fits the form of frame and directs pressure from glide rod radially.

Description

FIELD OF THE INVENTION

The application relates to a method and apparatus for protecting the internals of a pistol from damage due to the movement of the handgun slide hitting the frame.

BACKGROUND OF THE INVENTION

1. Prior Art
During regular firing of a pistol, as the slide of the pistol moves forward it hits the frame of the pistol, causing damage to both elements. The compression spring acts to buffer this impact by decelerating the motion of the slide as it moves towards the frame. Shooters have utilized different options to internally buffer the frame and slide of a pistol to prevent wear as well as reduce recoil. These methods involve utilizing compartments of compressible liquids, multiple spring setups, and frictional elements. These methods are flawed in that they often lead to unreliable setups that are prone to malfunctioning or damage. Most stock pistols only use friction and the compression of one spring to stop and rebound the slide mechanism. This method is functional, but causes extreme stress on the internal elements of the pistol. Methods to reduce this stress have been used in the prior art, but often lead to a diminished or insufficient rebound of the slide mechanism. This diminished or insufficient rebound can cause problems with the safety and/or accuracy of the weapon.
Presently, there exist certain buffer systems which use a flexible or compressible material to form a buffer between the pistol frame and slide, but these are often not endurable because of the constant strain applied to these systems which are inherently weak. Furthermore, this structural weakness is compounded by the configuration of these buffers which applies great pressure on certain parts of the buffer because the buffers are flat while opposing a pointed frame edge. Another failure of these buffer systems is that they often break apart because the slide rod in the center applies pressure to the inner portion of the buffer opposite to pressure on the outer portion of the buffer applied by the frame. This type of buffer fails quickly because all pressure input is transferred axially, causing greater stress on the buffer.
There exists a need for an internal buffer system which reduces damage to the pistol slide and frame without leading to radically diminished or insufficient rebounding of the pistol slide while increasing the durability and effectiveness of the buffer system over present buffer systems.
2. Objects and Advantages
Accordingly, several objects and advantages of this invention are:

- (a) To allow for greater protection of the pistol slide and frame from excessive wear;
- (b) To allow for reducing perceivable recoil;
- (c) To allow for the compression spring to continue to perform the function of rebounding the pistol slide.

Further objects and advantages of this invention will become apparent from a consideration of the drawings and ensuing description.

It is to be noted however, that the appended drawings illustrate only a typical embodiment of this invention and are therefore not to be considered limiting of its scope, for the invention may admit to other equally effective embodiments.

DETAILED DESCRIPTION—FIGS. 1, 3, 4, 8

With reference now to the drawings, the preferred embodiment of the glock buffer according to the present invention is herein described. As can be seen in FIG. 1, according to certain embodiments of the prior art, compression spring 10 is coiled around compression rod 11. Compression spring 10 is uncompressed while the internals of pistol 30 are not undergoing the stress of blowback operation.
As can be seen in FIG. 3, according to certain embodiments of the present invention, compression spring 10 is coiled around compression rod 11. Buffer piece 20 circumscribes compression rod 11. When compression spring 10 is compressed during blowback operation, buffer piece 20 is also compressed.
As can be seen in FIG. 4, according to certain embodiments of the present invention, compression spring 10 is coiled around compression rod 11. Buffer piece 20 circumscribes compression rod 11.
As can be seen in FIG. 8, according to certain embodiments of the present invention, wings 21 of buffer piece 20 cause buffer piece 20 to fit to pistol frame 13.
The foregoing description of the invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed, and other modifications and variations may be possible in light of the above teachings. The embodiment was chosen and described in order to best explain the principles of the invention and its practical application to thereby enable others skilled in the art to best utilize the invention in various embodiments and various modifications as are suited to the particular use contemplated. It is intended that the appended claims be construed to include other alternative embodiments of the invention except insofar as limited by the prior art.
The invention may be embodied in other forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

OPERATION—FIGS. 2, 3, 7

As can be seen in FIG. 2, according to certain embodiments of the prior art, as pistol 30 is affected by blowback and recoil, compression spring 10 compresses. As blowback operation occurs compression spring 10 compresses and pistol slide 12 hits frame 13 causing damage and wear to the frame 13 and the pistol slide 12 each time the pistol 30 engages in blowback operation.
As can be seen in FIG. 3, according to certain embodiments of the present invention, as pistol 30 undergoes blowback operation, compression spring 10 compresses. As compression spring 10 compresses, compression spring 10 places stress on buffer piece 20. Buffer piece 20 compresses as compression spring 10 presses on buffer piece 20, thus dampening and reducing the impact between the pistol slide 12 and pistol frame 13 which would otherwise damage the parts of pistol 30 overtime. Wings 21 of buffer piece 20 fit to frame 13 for a snug fit, increasing the contact surface between buffer piece 20 and pistol frame 13 relative to that of other buffer arrangements. This increased contact surface serves to lower the amount of pressure exerted on buffer piece 20, therefore reducing the damage to buffer piece 20 during blowback operation and increasing the durability of the buffer system of pistol 30.
As can be seen in FIG. 7, according to certain embodiments of the present invention, as pistol 30 undergoes blowback operation, compression spring 10 compresses, placing stress on buffer piece 20. As buffer piece 20 is stressed, it deforms itself under pressure such that the flexible center 22 expands both axially and radially. As the buffer piece's flexible center 22 expands radially, it pushes onto the outer edges of the buffer piece 20, thus ensuring the durability of the buffer piece 20, and the buffer system of pistol 30 as a whole.

CONCLUSION, RAMIFICATIONS, AND SCOPE

Thus, the reader will see that the method and apparatus will provide for creating a buffer for the movement of the internal rod and compression spring in the internals of a pistol wherein said buffer fits the form of frame and directs pressure from glide rod radially. While the above description contains many specifications, these should not be construed as limitations of the scope of the invention, but rather as an exemplification of a preferred embodiment of the invention. Many other variations and embodiments are possible.
Accordingly, the scope of the invention should be determined not by the embodiment illustrated, but by the appended claims and their legal equivalents.
