RU205989U1 - CUSHIONING BUTT - Google Patents

Abstract

Useful model The shock-absorbing butt is designed to reduce the force of impact on the shooter's shoulder after a shot. The shock-absorbing buttstock consists of a body (4) with a stepped cavity. The pusher (3) is installed in the body cavity (4) and is attached to the gun with a tightening screw (2) through the handle (1). The damping springs are installed in the body (4) after fastening the pusher (3) and are closed with a cover (5) fixed to the body (4) with screws (b). When fired, the handle (1) pushes the pusher (3) into the body cavity (4), compressing the springs (7). The springs (7), deforming, reduce the impact force and return the mechanism to its original position.

Description

Technical field to which the utility model belongs

The utility model relates to small arms, in particular to weapon butts.

State of the art

Known shock-absorbing butt plates made of various soft or elastic materials with slots installed on the butt (No. 2398173 published on 08/23/2010; No. 108587 published on 09/20/2011).

The disadvantages of such devices is a slight decrease in the force of the push to the shoulder and cheek of the shooter when shooting

There is also known a special butt for firearms, consisting of a body connected to the receiver, inside which there is a shock-absorbing device, which is a spring element, one end of which is rigidly fixed in the receiver, and the other is equipped with a roller interacting with the rear inner wall of the bracket (No. 2168144 published May 27, 2001).

The disadvantage of such a device is the complexity and high cost of the installation, since each model of the gun requires a special butt or the modification of the already installed butt is necessary, which will lead to a change in the appearance of the gun

It is also known small arms with a butt (No. 2464519 published on 10/20/2012) (prototype), consisting of a body and a shock-absorbing butt plate located on the back of the butt body, with which the weapon rests against the shooter's shoulder, a similar shock-absorbing butt plate is fixed in the butt body by means of a shock absorber, consisting of a cylinder and a piston, movably mounted in the axial direction inside the cylinder, integrally connected to the rod, which is partially extended from the shock absorber, the rod, respectively, is connected to the shock-absorbing butt plate or the butt body, and the cylinder is connected, respectively, to the butt body or the shock-absorbing butt plate, the shock absorber consists of of two chambers filled with oil, interconnected internally by a calibrated passage, as a result of the movement of the piston, the volume of one of the chambers decreases, and the volume of the other chamber increases, while the small arms contain a return spring, which at rest acts directly or indirectly on the shock-absorbing butt plate, moving it a certain distance from the butt body, and the shock absorber is located so that when firing, the butt tends to fall down from the shooter's shoulder and cheek.

The disadvantage of such a device is the high cost of manufacturing, the possibility of freezing of the used oil in the shock absorber chambers when using the weapon in a climate with low temperature conditions, which will lead to its unstable operation.

Thus, there is a need for a low cost cushioning device with a simplified cushioning system.

Disclosure of a utility model

The task of the utility model is to create a cheap shock-absorbing device with a simplified depreciation system.

This is achieved due to the fact that, unlike known technical solutions, the shock-absorbing butt consists of a pusher installed in the butt body and having blind holes for fixing the position of special shock-absorbing springs, attached to the weapon with a tightening screw, while the screw holds the butt handle into the pusher holes special shock-absorbing springs are installed, damping the shock when fired, closed with a cover that has holes for fixing the position of special shock-absorbing springs and is attached to the body in such a way that when fired, the impact is transmitted through the handle and the pusher moving into the body, while the springs are compressed accordingly, when compressed of the springs, the impact force decreases, after which the springs return the mechanism to its original position, as shown in Fig. 1.

The advantage of this technical solution is the simplicity of manufacture, the absence of hydraulic damping systems capable of failing in climatic conditions with low ambient temperatures, a decrease in the force of impact on the shooter's shoulder when firing and the possibility of a non-fitting decrease or increase in damping for guns of various calibers by replacing shock-absorbing springs, the need to install shock-absorbing butt pads.

Description of drawings

FIG. 1 shows a cross-section of a shock-absorbing butt.

Implementation of the utility model

The shock-absorbing stock consists of a handle (1), a clamping screw (2), a pusher (3), a body (4), a cover (5), screws for fastening the cover (6), shock-absorbing springs (7),

The shock-absorbing butt works as follows.

When fired, the impact force is transferred to the pusher 3 through the handle 1 and the clamping screw 2 that secures them to the gun, while it is displaced into the cavity of the body 4. When the pusher 3 is displaced, the shock-absorbing springs 7 are compressed due to their stop in the wall of the cover 5, fixed to the body screws 6, in such a way that the force of the shock absorbs, and the shooter perceives only a slight shock from the shot in the shoulder, after which the shock-absorbing springs 7 are released and return the mechanism to its original position.

Claims (1)

Shock-absorbing buttstock, consisting of a handle with a through hole for the location of a tightening screw, a pusher with blind holes for installing shock-absorbing springs, a ledge for holding in the body, a through stepped hole for installing a tie screw and attached to the gun through the handle with a tie screw after installation in the body , a body having a cavity for displacing the pusher into it when firing, and ledges for holding the pusher in the body, shock-absorbing springs installed in the blind holes of the pusher after it is installed in the body, and attaching to the gun through the handle with a tightening screw, closed with a cover made in the form arches for more precise fixation on the shooter's shoulder and having blind holes for fixing the shock-absorbing springs, fixed to the body with screws and holding the spring, thus, when fired, the handle displaces the pusher into the body cavity, compressing the shock-absorbing springs and reducing the impact force into the shooter's shoulder.
