Title Handgun and pistol

DESCRIPTION

The invention relates to a hand weapon, consisting of a barrel with ammunition feed, a trigger and a stock, wherein the stock may optionally consist of several components, in particular of a handle and/or a shoulder rest and/or a barrel base and/or supports and/or barrel casings.

Hand weapons and fist weapons have been around for a long time in a wide variety of designs. An example of a fist weapon is the pistol, which was originally designed with a flint lock and a handle-like curved stock. The best-known designs are the Mauser pistol, the Parabellum pistol, the Browning pistol and the Walter pistol. There are also revolvers, i.e. pistols with a rotating drum magazine attached behind the barrel.

Today, handguns and fist weapons are mainly used for competition purposes, sometimes with rapid firing (e.g. biathlon) and as weapons in military operations.

Such hand and fist weapons have to be very stable due to the high kinetic energy that must be imparted to the ammunition. For this reason, the hand and fist weapons known to date are very solid and therefore heavy.

Another requirement that must be taken into account when designing a handgun is that the heat generated when the weapon is fired must be dissipated as quickly as possible. The solid material must therefore have good thermal conductivity.

For this reason, the hand and fist weapons known to date are predominantly made of metallic materials, as these are solid and have good thermal conductivity.

However, since the metallic materials generally have a very high specific weight, the main problem of the heavy handling of such weapons remains. In addition, it is difficult to dampen such weapons, since the vibrations caused by the firing of the ammunition are transmitted directly to the user through the metallic materials and are hardly dampened.

It is therefore the object of the present invention to provide a hand and fist weapon whose weight is reduced and which ensures optimal damping when firing the weapon.

The object of the present invention is achieved in the generic subject matter in that the shaft is made of a composite material.

Hand and fist weapons designed in this way can be constructed in a geometry that is identical to the conventional shafts made of wood (so-called oil shafts), plastic shafts (duroplastics or thermoplastics) or aluminum with rubber or plastic applications. The main advantage of hand and fist weapons whose shafts are made of a composite material is that the composite material achieves a significant reduction in weight while still maintaining high thermal resistance and better damping of vibrations.

By choosing a suitable composite material, shrinkage and expansion due to temperature is avoided, i.e.

The set balance is not changed. The temperature independence required for precise use is maintained. In addition, the choice of a suitable composite material makes decontamination of a chemical or biological substance easier, as the material is more resistant to chemical substances and can be decontaminated using known thermal processes due to the material's temperature resistance.

The vibrations that occur when the weapon is fired are dampened to a much greater extent than with stocks made from conventional materials. The composite material is constructed in a mold, usually with a core, and the necessary metal components are laminated into the component where necessary.

Depending on the shape or filling components of the component, the core can consist of aluminum or foam, which remains in the component as a lost core, or the workpiece is removed from the core after curing.

In a handgun or fist weapon with a rapid rate of fire (e.g. for biathlon), the composite material ensures that vibrations caused by the shot are significantly dampened and the rate of fire can be increased. The balance of the overall system is not disturbed by the low temperature dependence of the composite stock.

In an advantageous embodiment of the invention, it is provided that at least one element with a higher specific weight is arranged in the shaft for shifting the center of gravity.

-A-

Due to the high weight savings when choosing the composite material for the stock, elements can be integrated within the component that allow the entire system of stock and weapon components to be set in a general or individual balance system selected by the user. Due to the weight savings of the main component, the selected balance elements mean that the total weight is lower than that of a conventional design.

In a particularly advantageous embodiment of the invention, the element(s) is/are arranged so that it can be moved in the shaft, in particular in the handle and/or in the barrel base. The dynamic balance elements are integrated for general and individual adjustment in order to enable the weights to be arranged at will, which makes it easier to reduce the weight of the shaft. The dynamic weights enable individual settings for different shooting positions (e.g. standing, lying down, etc.).

In another special embodiment, the element is arranged so that it can be moved using a special tool. This particularly advantageous design means that the hand weapon or fist weapon can be adjusted to the specific requirements at practically any time, especially during training. In competition, the desired and proven setting can then even be set for different sports or different positions during the competition.

In a further embodiment, it is advantageously provided that the element is arranged so that it can be moved by means of an adjustment device. In this embodiment, no special tools are required. This means that the

Adjustment is made much easier and you don't have to carry an additional part around with you.

In a further advantageous embodiment, the composite material consists of a fiber-plastic combination. With such new composite materials, it is particularly advantageous that the positive properties of the various combined materials result in synergistic effects. In a particularly advantageous embodiment, the fiber material consists of glass, carbon, aramid, boron or hemp, with hemp as a natural fiber being a renewable raw material. The plastic material for reinforcing the fiber material is advantageously made of polyester resin, vinyl ester resin, epoxy resin, polyamide or copolyamide. These matrix materials make a significant contribution to structural strengthening and vibration damping. A carbon fiber-polyamide matrix has proven to be a particularly advantageous material for composite materials in hand weapons and fist weapons.

The invention is described in a preferred embodiment with reference to the drawings, wherein further advantageous details can be taken from the figures of the drawing. Functionally identical parts are provided with the same reference numerals.

The figures in the drawing show in detail:

Figure 1 is a front view of an embodiment of the hand weapon,

Figure 2 shows a section of the hand weapon according to section line l-l in Figure 1.

The weapon component designated with reference number 1 in Figure 1 is a barrel with an ammunition feed and breech (not shown).

A trigger 2 is attached to this in a known manner. Shaft 3 is arranged below the tube 1. The shaft components can be designed as a complete part or broken down into individual parts (handle, shoulder rest, supports, tube casings, etc.). The composite material is constructed in a mold with a core, whereby the necessary metal components can be laminated into the component if necessary. Depending on the shape or filling component of the component, the core can consist of aluminum or foam, which remains in the component as a lost core, or the workpiece is pulled off the core after hardening. The shape of the shaft 3 can be designed in both a known and a new way that corresponds to an ergonomic shape.

Elements 5 are integrated into the shaft 3 or into the individual components of the shaft 3, which can be moved or not, in particular in the handle or in the tube base. In the simplest case, the dynamic balance elements 5 can be weights that can be moved individually using a special tool or integrated adjustment devices. Displacement devices 4, in particular tubes, are used to move the movable elements 5. The balance elements 5 can be moved and fixed in these according to individual requirements. Static balance elements 5 can be introduced for basic balance in the left part of Figure 1.

In the shaft 3 made of carbon fiber composite material, hollow profiles, e.g. made of aluminum, titanium or fiber composite materials, are inserted into a lost core, which are equipped with a movable weight. The weight in the displacement device can be adjusted to the individual sense of balance using a fine threaded screw. In addition, static and dynamic

Balance elements integrated for general and individual adjustment. The intentional arrangement of the weight is made easier by reducing the weight of the stock. The dynamic weights enable individual settings for different shooting positions (e.g. standing, lying down, etc.).

In a handgun for military use, the stock components (shoulder rest and handle) are made of suitable composite materials. Static balance elements are inserted into the stock components to balance the entire system. The composite materials (e.g. carbon fiber with a polyamide matrix) are designed in such a way that the entire weapon can be disinfected in an autoclave, for example, if it is contaminated with biological weapons.

The connection between tube 1, trigger and shaft 3 is achieved by means of positive and/or force locking. This can be achieved, for example, by screwing or by using heat-resistant adhesives.
