Abstract

In a ball mounting, especially for fitting in armoured glass panes (1), with a ball-type housing (2), a ball (3) rotatably fitted in the spherical hollow (6) of the housing (2) and an attachment secured to the ball (3) for a hand firearm, in which the ball (3) and the attachment have an aligned bore through which the shots (31) fired from the weapon may pass, the stress on the pane (1) is reduced in that the attachment is flexibly spring-mounted so as to be longitudinally movable. The ball mounting may therefore also be used in a pane (1) which has been shot-damaged on the outside, without being torn from its securing system.

Description

Ball mount

The invention relates to a bullet mount, in particular for installation in bulletproof glass panes, with a spherical sleeve, a spherical body which is rotatably mounted in a spherical opening of the spherical sleeve and which has a bore for the passage of the projectiles fired by the weapon, and a connecting piece fixed on the spherical body for attaching a hand gun.

In a known device (DE-OS 28 51 527), the ball mount is installed in an armored glass pane, for example of a motor vehicle. The ball sleeve is non-positively, frictionally or positively connected to the bulletproof glass pane by means of a screw, clamp, or adhesive connection or the like, and the spherical body is rotatably fixed in the spherical opening of the spherical sleeve such that it can be freely pivoted at least within a cone with a cone angle of 60 °. With such a device, targets can be sighted and combated from inside the vehicle through the bulletproof glass pane. For this purpose, only the suitable weapon is to be attached to the connecting piece on the spherical body. In such a device, the weapon can be rotated via the connecting piece and the spherical body, but is rigidly connected in the direction of the inner axis of the barrel of the weapon and cannot be moved backwards with the spherical sleeve and therefore with the bulletproof glass pane. When the weapon is fired, the shot pulse is largely transmitted to the target or the armor holding the ball sleeve in this device. It has been shown that a disk damaged by external shelling is no longer able to intercept the firing pulse of the firing weapon. The carriage is usually torn out of the window. In addition, due to the rigid connection of the weapon and the armored glass pane, the entire shot pulse attacks the weapon. In the case of pistols which are generally not designed to rigidly absorb the recoil forces, this leads to premature failure.

The invention is therefore based on the object of providing a ball fat in which such disadvantages are at least largely avoided, i.e. , the bulletproof glass pane is subjected to less stress when the weapon is fired and no hard impacts are transmitted to the weapon itself.

This object is achieved in that the Connection piece is elastically cushioned longitudinally movable relative to the ball body.

This bullet mount partially absorbs the return energy released when the weapon is fired. The bullet and the shooter bring the weapon to a standstill after it has been fired before it hits an attack. This advantageously reduces the impact forces on the tempered glass pane. The ball mount remains anchored in it even in the case of panes damaged by external bombardment and is not torn out.

The further advantage is that the weapon can perform a return movement, so that the recoil forces do not have to be absorbed rigidly by the weapon, which contributes considerably to protecting the weapon.

An advantageous embodiment provides that the ball mount has a first mount part rigidly attached to the ball body, a second mount part to be fixed to the weapon and axially displaceably attached to the first mount part, and a return spring which counteracts the axial displacement of the second mount part. The first carriage part is rigidly connected to the spherical body and the second carriage part is rigidly connected to the weapon. When the weapon is fired, the second gun part performs an axial movement away from the target relative to the first gun part. This movement is slowed down by the return spring and is finally absorbed. The return spring prevents the weapon from striking stops and thus prevents impacts on the target. The ball mount can be adapted to different weapon types by suitable selection of the spring characteristic. In a preferred embodiment, the first and second mount parts are arranged at least partially coaxially surrounding one another. This arrangement enables a compact design and a symmetrical distribution of force on and within the ball mount. This advantageously contributes to the fact that the return spring is arranged coaxially between the first and second carriage parts.

A simple attachment of the ball mount is advantageously achieved in that the first and second mount parts are connected to the ball body or the weapon by means of screw connections and / or bayonet locks. The spherical body preferably has a screw connection and the weapon has a bayonet lock. This allows the weapon to be removed and installed quickly.

One embodiment of the ball mount provides that the first mount part is connected at its front end to the spherical body and at its rear end has a plate for the rear end of the helical return spring surrounding the mount part coaxially and the second mount part is designed in the form of a sleeve , the return spring surrounds and forms with its front end a seat for the front end of the return spring and is axially displaceably mounted on the first carriage part, and the rear end has a receptacle for the weapon. Such ball mountings have a small diameter and a short component length and are of relatively low weight. They are also easy to manufacture, since almost only turned parts are used.

In a preferred embodiment it is provided that the plate of the rear end of the first carriage part is a forms gas-tight storage for the sleeve-shaped second mount part and the receptacle for the weapon is arranged at a distance from the rear end of the first mount part. The recoil of the weapon, for example for weapons with returning tubes, can be increased with such a bullet mount, the armored glass pane nevertheless being subjected to a small force.

An undamped recoil is advantageously achieved in the ball mount in that the front end of the receptacle has a tubular extension which is guided gas-tight axially displaceably in the bore or in an extension of the bore of the first mount part. The propellant gases can escape freely from the barrel of the weapon through the bore of the receptacle through the bore of the first mount part.

In the case of a ball mount with damped recoil, the bearing of the front end of the second mount part is gas-tight, and the bore of the first mount part has at least one in which between the first and second mount parts and from the mounting of the front end of the second carriage part to the plate of the first carriage part extending return spring chamber opening transverse bore. This ball mount is preferably used for pistols that are not designed for rigid absorption of the recoil forces.

In one embodiment of the invention it is provided that the ball mount is designed for connection to the barrel of the weapon. While it is irrelevant in the case of a weapon with a rigid barrel, whether the gun attacks the front barrel end or the housing of the weapon, it can be used in the case of weapons with a movable barrel to support or reduce the return of the barrel relative to the body of the weapon, be useful to connect the barrel to the bullet. In the case of the last-mentioned weapons, if the ball mount is connected to the housing, it must be ensured that the barrel can move in its longitudinal direction relative to the ball mount.

Further advantages and details of the invention emerge from the following description, in which three preferred exemplary embodiments are explained in more detail with reference to the drawing.

The ball mount 4 shown in FIG. 1 has a spherical sleeve 2 built into an armored glass pane 1 and a spherical body 3 which is rotatably fixed in the spherical sleeve 2. In the embodiment shown in FIG. 1, the bulletproof glass pane 1 consists of a glass layer for the sake of simplicity, but the bullet mount according to the invention can also be used on bulletproof glass panes with two or more glass layers. The ball sleeve 2 is inserted into a circular-cylindrical or rectangular opening 6 of the disc 1 and connected to the disc 1 with the interposition of a rubber-elastic putty. The ball sleeve 2 consists of two housing halves 8 and 9 which are connected to one another by means of screws 10. A spherical opening 11 is machined into the ball sleeve 2 and serves as a bearing for the ball body 3. A sealing ring 13 embedded in an annular groove 12 prevents the ingress of liquid and gas from the outside.

At the inner end of the bore 14 of the spherical body 3, the front end 16 of a first mount part 17 is fixed via a screw connection 15. The rear end 18 of the first carriage part 17 has a plate 19 on which the rear end 20 of a helical return spring 21 is supported. The spring 21 extends around the first mount part 17 towards its front end 16 and is supported with its front end 22 on the front end 23 of the second mount part 24. This front end 23 is axially displaceably mounted on the tubular body of the first carriage part 17. The The rear end 25 of the second mount part 24 has a receptacle 26 for the barrel 5 of a weapon, which can be fastened, for example, via a bayonet lock 27. The spherical body 3, the first mount part 17 and the receptacle 27 each have a bore 14, 29, 30 which is coaxial with the core axis 28 of the barrel 5 for the free passage of the projectile 31.

The mode of operation will be explained below. The impulse caused by the firing of the projectile 31 causes a return movement of the barrel 5 and thus of the second mount part 24 connected to the mount 5 via the receptacle 26 , which gradually absorbs the return energy through deformation. Due to the return, the second carriage part 24 is displaced axially with respect to the first carriage part 17, as shown in FIG. 2. After the return spring 21 has brought the weapon to a standstill by absorbing the return energy, which is also partially taken up by the shooter, it relaxes and leads the second mount part 24 back to the starting position shown in FIG. 1.

The forces acting on the bulletproof glass pane 1 in this damping process are considerably lower than in the case of conventional ball mountings. As a result, on the one hand, the disc 1 is exposed to lower loads and, on the other hand, use of the mount is still possible even with an externally bombarded disc 1 without the ball sleeve 2 being torn out of its seat.

3 - 6 show two in structure and function in the borrow similar spherical guns, so that only the differences between the three spherical guns will be discussed below.

The ball mount 4 shown in FIGS. 1 and 2 is particularly suitable for weapons with return pipes, since it increases the recoil. This is achieved in that the receptacle 26 for the barrel 5 of the weapon is arranged at a distance from the rear end 18 of the first mount part 17. When the projectile 31 is fired from the barrel 5, the propellant gases pass through the bore 30 of the receptacle 26 into an intermediate space 32 and through the bore 29 of the first mount part 17 into the bore 14 of the spherical body 3 and finally into the open. While the projectile 31 is located in the bores 29 and 14, there is a pressure in the intermediate space 32 corresponding to the pressure of the propellant gases the pressure cannot drop. This pressure supports the return movement of the second carriage part 24 by acting on the front surface 33 of the receptacle 26 which closes off the intermediate space 32. The front surface 33 namely increases the total size of the surfaces of the weapon on which the propellant gases exert a force which moves the barrel back. With the force of the propellant gases exerted on the front surface 33, the second mount part 24 is additionally accelerated to the rear (here to the right in FIGS. 1 and 2). As soon as the projectile has left the bore 14 of the spherical body 3, the propellant gases escape from the bores 30, 29 and 14 and also from the intermediate space 32. The force acting on the front surface 33 disappears. The kinetic energy (return energy) of the moving parts (second carriage part 24, receptacle 26 and weapon) is absorbed by the return spring 21 and possibly by the shooter and the second carriage part is then returned to its starting position by the spring, possibly supported by the marksman pushing against the weapon.

The ball mount shown in Figs. 3 and 4 'leaves the recoil of the weapon almost unaffected. This is achieved by a tubular extension 34 at the front end of the receptacle 26. This approach 34 engages in a cylindrical extension 35 of the bore 29 at the rear end 18 of the first carriage part 17 and is axially displaceably guided therein. An escape of the propellant gases into the intermediate space 32 is prevented by a gas-tight mounting of the extension 34 in the extension 35. The plate 17 is not gas-tight in the second mount part 24, so that an almost undisturbed gas exchange between the intermediate space 32 and the spring space 36 in front of it is possible. The propellant gases can therefore only attack the weapon and the projectile 31.

The ball mount 4 ' ¹ shown in FIGS. 5 and 6 is particularly suitable for pistols, since it dampens the recoil of the weapon. This is achieved in that part of the propellant gases is directed as in the ball mount 4 'of FIGS. 3 and 4 via the extension 34 and the extension 35 past the gap 32 into the bore 29 of the first mount part 17. This bore 29 has bores 37 in the spring chamber 36 of the return spring 21, through which part of the propellant gases can escape. The spring chamber 36 is sealed gas-tight on the one hand by a suitable fit of the front end 23 of the second mount part 24 on the body of the first mount part 17 and on the other hand by a suitable fit of the plate 19 in the second mount part 24. The pressure prevailing in the spring chamber 36 due to the propellant gases causes a pressure at the seat 38 of the spring 21 attacking force, which counteracts the return of the weapon via the second mount part 24. The cross bores 37 can be made radially or at an angle to the normal to the axis 39 of the ball mount 4 ″ in the wall of the first mount part 17. The speed of the propellant gases flowing into the spring chamber 36 can be optimally adjusted by a suitable choice of the angle. This ball mount 4 ″ can also be used to use weapons, for example pistols or the like, which are generally not designed for rigid absorption of the recoil forces.
