Description

The invention relates to a recoil damping device, which is attachable to a handgun and / or which is attached to a handgun.

For handguns occur in firing i. A. significant Recoil forces on. Through this the weapon is going against the weft direction, i. towards the shooter's body accelerated. This can cause the weapon against hits the shooter's body, causing severe pain. To prevent this, the shooter presses the Weapon when mooring firmly against his body, in particular his shoulder.

To those who act on the body of the shooter during the recoil Reducing forces has been suggested To provide weapon housing with a damping device. This is when you put the weapon between the body of the shooter, and the weapon housing, and absorbs one Part of the energy released during the recoil.

For example, that described in DE-T2 694 04 180 Recoil damping device in the form of a pocket, attached to the shoulder piece of a rifle is. The bag is made of a material which not or only slightly extensible, e.g. made of fabric, and is filled with viscoelastic rubber.

From US 4,683,671 is a recoil damping device known, which is attached to a rifle, and which an elastic outer jacket comprising a substantially having rectangular cross-section. The outer jacket is filled with a shock absorbing material.

FR 2 167 317 shows, particularly in FIG. 10, a rear shock absorber for a rifle stock, with a rubber cap, in the recesses in the shot a yielding in To initiate weft direction. The coherent contact surface on the shooter's shoulder, the effective area, hardly enlarges.

The same applies to US Pat. No. 2,438,142 which discloses a recoil damper for rifle sticking according to US Pat Oberbegrift of Ansprüchs 1 shows, in which the recoil damper formed by an air cushion, however surrounded by a stiff sleeve, which is the enlargement the effective area is limited.

The invention has set itself the goal of the known To develop recoil damping devices.

It achieves this goal through the subject-matter of the claim 1. Accordingly, a recoil damping device is which can be attached to a handgun, designed, that their effective area - between a first State of the device in which this when applying the weapon pressed against the body of a shooter becomes, and a second state at firing - strong increased.

Advantageous embodiments of the invention are in the Subclaims defined.

The term "effective area" is here generally the when creating the weapon, and then firing the shooter's body touching part of the outer surface the recoil damping device understood, in particular the surface part over which the recoil forces of the Damping device directed into the body of the shooter become.

For example, the effective area of that part of the Dämpfvorrichtungsfläche be that when creating and then Firing the shoulder, cheek or the Touched the shooter's upper arm (e.g., when the device attached to the shoulder piece of a rifle). It is conceivable, e.g. also, that the effective area of that part the outer surface of the device is which the palm of the hand touched by the shooter (e.g., when the device attached to the handle of a pistol).

The invention is based on the following basic idea: The Damping device is designed so that their Effective area - between a first state of the device, in which this when applying the weapon against the Body of a shooter is pressed, and a second Condition at firing - greatly increased. This will the repulsive force on the body when firing of the shooter spread over a larger contact surface. This Reduces the pressure on recoil on the body is exercised; the firing is called "more pleasant" felt less painful. It is advantageous if the recoil force substantially uniform over the entire effective area distributed on the body of the shooter acts.

Particularly advantageously, the damping device is designed such that their effective area by more than 15%, in particular by more than 25%, more preferably by more as 35%, or increased by more than 50% or 75%. By the particularly large increase in the effective area is a in particular reduced recoil pressure achieved.

The device may e.g. be integrally formed, and for example, consist of an elastic material.

Particularly advantageously, the device has an outer jacket on. This is preferably made of an elastic Material. Particularly advantageous is the outer jacket made of an elastomer, i. a fabric with rubbery Elasticity, such as natural rubber, Chlorinated rubber, polybutadiene, polyurethanes, or silicone rubber. Elastomers stretch during strong pull until more than twice the initial length. at they have a high tensile strength and great elongation Stiffness, and take their original after stress Shape again. Preferably, the inventive Outer jacket of Dämpvorrichtung designed so that he in the case of a firing fee of more than 15%, especially advantageous stretches by more than 30% or 50%.

Preferably, the outer jacket with a shock absorbing Material filled. This converts a part of Recoil energy into heat. As impact absorption material For example, an elastomer, e.g. Rubber can be used, for example in compact or non-compact form (e.g., foamed or with a honeycomb structure Mistake). The outer jacket is advantageous with a Variety of small absorption elements e.g. filled out of rubber, which move relative to each other at firing.

The recoil damping device can be attached to a handgun, e.g. a rifle, a machine gun, a pistol, or a submachine gun. Advantageous if the device is e.g. at a rifle its shoulder piece, or e.g. at a gun at the Handle attached.

Particularly advantageous, the recoil damping device a support element, by means of which the device attached to the handgun. Preferably the connection between weapon and device, in particular between the weapon and the carrier element, detachable. The detachable Compound can e.g. designed as a latching connection be. For example, the damping device may be formed be that they each at one of several, identical Handguns can be attached. Advantageous is an embodiment in which the device to each one of several handguns different Type can be attached, e.g. on different rifles.

In an alternative embodiment, the damping device also indissolubly coupled to the weapon, e.g. With this welded or riveted.

In Fig. 1 is a cross section through a Rückstoßdämpfvorrichtung 1 according to an embodiment of the present invention Invention in a first, unloaded state shown.

The damping device 1 has at its front end (in the drawing on the left) one made of metal or plastic-made carrier plate 3. This is on the rear end surface 2a of a shoulder piece 2 of a Rifle (shown in dashed lines in the drawing) latched or screwed. From the back, in the Drawing right outer edge of the support plate. 3 from a groove 6 extends. This is integral with the Support plate 3 is formed, tapers backwards towards, and is opposite to the outer surface 3c of the support plate 3 inclined to the outside.

The damping device 1 also has a damping element 4 on, which consists of an elastomeric sheath 4a, and a Shock absorbing element 4b exists. The elastomeric sheath 4a has a uniform thickness of about 0.5 cm, and wrapped the shock absorbing element 4b. The inner surface of the coat 4a and the outer surface of the element 4b touch each other, and are frictionally connected with each other. The Shock absorption element 4b is integrally formed, and Although made of a shock-absorbing material, here rubber. The front end surface of the elastomer sheath 4a is attached to the rear end surface 3a of the support plate 3, and the inner surface the groove 6 glued or sprayed on this. The Outer contours of the elastomeric sheath 4a, and the shock absorbing element 4b are unloaded in the one shown in FIG State in cross-section substantially rectangular, with rounded corners, and slightly behind each outside arched outside edges. In the unloaded state has the damping element 4 has a length 1 of about 6 cm, a height h of about 8cm, and as shown in FIG. 4, a width b of about 4 cm.

The elastomer sheath 4a and the shock absorbing member 4b are, as shown in Fig. 4, in longitudinal section substantially oval. The outer contour of the elastomer jacket 4a corresponds essentially in terms of shape and size that of the groove 6 shown in Fig. 1 of the support plate 3, as well as that of the rear end surface 2a of the rifle shoulder piece Second

Before the use of the rifle, the damping device becomes 1 on the rear end surface 2a of the rifle shoulder piece 2 snapped on, i. firmly connected to the rifle (Fig.2), namely by means of a (not shown) locking connection. Then the shooter puts the rifle on and pushes while the damping device 1 firmly backwards against his Shoulder 7, i. in the direction of an arrow P. This is the elastomer sheath 4a, and the shock absorbing member 4b slightly deformed. The damping element 4 then has a length of 1 of about 5cm, and the rear end surface 4a 'of the damping element 4 fits ergonomically the front shoulder surface 7a on.

When applying the rifle, the effective area 8, i. here: the touching the front shoulder surface 7a of the shooter Part of the outer surface of the elastomer jacket 4a a height i of about 7 cm, and according to FIG. 5, a width c of about 3 cm. The outer contour of the active surface 8 is substantially oval. Due to the mentioned ergonomic adaptation of the Dämpfelements 4, the effective surface 8 is slightly inward arched (see Fig. 2).

Fig. 3 shows the damping device shown in Fig. 1 and 2 1 at a third state, in which a Shot is fired from the rifle. By at firing occurring strong recoil force is the damping device 1 in the direction of arrow P - still essential stronger than when putting on - against the shoulder 7 of the Shooters pressed. Here, the elastomeric sheath 4a, and the impact absorbing member 4b is greatly deformed. The Damping element 4 then only has a length 1 of about 2cm. (Note: in Fig. 3, the state is maximum Deformation of the damping element 4 shown).

By the deformation of the damping element 4, the following Effects achieved: on the one hand, a part of the Recoil energy is converted into heat, and thereby acting on the shoulder 7 of the shooter Recoil force reduced.

On the other hand, the effective area 8, i. here: the the front shoulder surface 7a of the shooter touching part the outer surface of the elastomer jacket 4a greatly increased. This is then e.g. significantly larger than the rear end surface 2a of the rifle shoulder piece 2. In the present Case she has a height i of about 12cm when firing, and according to FIG. 6, a width c of about 5 cm.

The outer contour of the active surface 8 remains substantially oval. As shown in Figs. 2 and 3, the deformation is the damping element 4 so strong that parts of those sections the damper outer surface, not initially towards the rear (i.e., up or down, for example or laterally), at firing a portion of the effective area 8 form.

According to Fig. 3, the damping element 4 is formed so that the (remaining after the damping by the damping element 4) Repulsive force substantially uniform over the entire active surface 8 distributed in the shoulder 7 passed becomes. For example, those in the central area of the Working surface 8 acting on the front shoulder surface 7a Forces F2 and F3 are essentially the same size as forces F1 and F4 in the upper and lower end of the Working surface 8 act on the front shoulder surface 7a (Similarly, for example, with regard to not shown, in left and right end regions of the active surface 8 forces acting on the shoulder compared with the forces acting in the other active surface areas) ,

By distributing the recoil force to a relative large effective area 8 is compared to conventional rifles at firing a much lower pressure on the Shoulder of the shooter exercised.

After firing, the damping element returns to the position shown in FIG. 2 shown state back. By a (not shown) Actuating mechanism can then be preferred from Protect the locking connection between shoulder piece 2 and Support plate 3 are released, and thus the damping device 1 are removed from the rifle, if necessary to be exchanged.
