Abstract

The invention relates to a barreled firearm (1) having a base plate (2), a ball bearing (8) mounted in the base plate, and a barrel (4) having a ball (7) at the end (6), the ball (7) being rotatably mounted in the ball bearing (8). The barreled firearm (1) is characterized in that the ball (7) can be fixed in the ball bearing (8). The ball (7) is fixed, i.e. locked, in the ball bearing (8) by means of a pressure plate (9) which is spring-loaded. The pressure plate (9) is preferably annular. At least one aid means (30) is provided, which can release the fixing of the ball (7) in the ball bearing (8) so that the ball (7) is rotatable in the ball bearing (8). In order for the barrel (4) to be able to be elevated while the ball (7) is released from its fixation, the at least one means (30) is attached to the barrel (4), and means (30) and barrel (4) are simultaneously operated and moved by an operator. Due to this structural design, additional support and elevation of the barrel (4) can be dispensed with. These functions are implemented by means of the clampable ball (7).

Description

DESCRIPTION

Barrel weapon

The invention relates to a barrel weapon, for example in the caliber 81 mm. The invention relates in particular to a mortar weapon and the use of a base plate without a single or bipod.

Mortars are part of the basic equipment of infantry and grenadier troops. As a simple light high-angle weapon, they are used to provide direct support to combat units with indirectly directed high-angle fire. These guns fire in the upper angle group and are therefore suitable for acting against a target from safe cover.

Mortar weapons, also 81 mm in size, are held by a monopod or a bipod. The use of a tripod is also known. Often these legs are mounted on or are connected to a base plate. When used on soft ground, these legs are also often provided with claws. These are driven into the ground with the first shot and thus create a solid base for the gun barrel. In addition, a height direction of the weapon barrel takes place via the one or two legs.

AT 227 119 B discloses a bottom piece storage for grenade launchers with ball studs and ball sockets, which are designed as rotating bodies. The ball pivot is locked in the ball socket by pivoting a grenade launcher tube from an insertion direction. In one embodiment, a locking ring is provided. In order to ensure that the ball socket or the locking ring is carried along in every elevation of the grenade launcher barrel when firing all around, the ball socket is pivoted in such a way that a plane located through an upper edge of the ball socket forms an angle with the main plane of the base plate. If, however, the locking ring is not taken, the grenade launcher barrel cannot be lowered sufficiently deep in the new lateral direction. From DE 10 2006 005 663 B3 a barrel weapon, in particular a mortar or howitzer, with at least one weapon barrel and a base plate is known. The base plate has a first and a second side opposite the first. The first side has claws or thorns. This barrel weapon is characterized in that the second side has an anti-slip covering and the base plate can be turned when it is ready for use. This means that the gun can be used on both soft and hard surfaces. The spikes or claws enable use on soft ground. The second side is smooth and can be used on hard surfaces. The first end of the weapon tube has a ball which is suitable for the angle-independent reception of the ball in a ball socket of the base plate. In a first embodiment, the base plate has two ball sockets, one on the first side and another on the second side. Alternatively, only one ball socket can be provided in another embodiment, which can be fastened on both sides of the base plate. This barrel weapon is supported by a bipod.

DE 20 2015 001 085 U1 describes a mortar training device comprising a launch tube with a front end, a rear open end, a tube wall and a removal opening. The rear end of the launch tube is pivotably connected to a base plate. A support with a sighting and alignment device is designed as a height-adjustable bipod.

A base plate for the M224 mortar weapon is known from US Pat. No. 8,277,141 B1. This has an opening for receiving a spherical end of a weapon barrel. In addition, a so-called base cap is provided, which is rotatably mounted in the opening. At a certain angle, the spherical end can be inserted directly into the base cap. With a different angle setting, it is not possible to separate the weapon barrel from the base plate. Thus the mortar system can be carried fully assembled.

The disadvantage of the previously known solutions is that the height adjustment of the barrel weapon takes place via the one or two legs by adjusting the leg length (s). This is complex and often time-consuming.

The object of the invention is to propose a simple and improved leveling of a mortar weapon or a barrel weapon.

The object is achieved by the features of claim 1. Advantageous refinements can be found in the subclaims.

The invention is based on the idea of dispensing with a known one-, two- or three-legged weapon and showing a barrel weapon with a so-called "no-leg". Saving a separate support for the barrel has the advantage of reducing the weight of the barrel weapon The basic weight of the gun is minimized. In order to be able to do without a leg, the invention provides to be able to fix a mortar barrel mounted on a ball in a ball bearing in a base plate in this base plate or ball bearing, but to be able to remove the fixation again for height adjustment. The sphere can be produced using 3D printing, among other things. It can have an inner honeycomb structure in a steel alloy or the like.

The weapon barrel can be fixed or fixed in the base plate solely by means of this ball, so that, in a continuation of this idea, it is provided that the ball can itself be clamped in the ball bearing.

The ball bearing has a specified ball diameter. The ball can be clamped for example via a frictional connection. In order to be able to ensure a corresponding clamping torque, this frictional connection can be created by means of at least one spring and at least one pressure plate. The pressure plate, which is preferably designed as a ring, presses on the ball. The pressure plate is supported by the at least one spring. The at least one spring is preferably a compression spring. Helical springs or disc springs can be used as compression springs. This is preferably at least one set of springs. Several springs or spring assemblies can be used.

The operation for adjusting the height of the gun barrel can also be simplified. The clamping or the frictional engagement of the ball with the base plate can be released via at least one aid. To release, work is done against the at least one spring in order to lift the pressure plate. This releases the bullet so that the gun barrel can be moved. The release of the clamping can preferably take place continuously and as required. As soon as the desired setting has been reached, i.e. the desired target height of the weapon barrel has been set, the ball can be fixed again and the frictional connection re-established.

In a further development of the invention, the at least one aid is connected to the weapon barrel in such a way that the weapon barrel can be adjusted in azimuth and elevation via the at least one aid, preferably together with the aid. So canting of the weapon raw res can be compensated manually.

At least one handle can function as the at least one aid. However, two movements are preferred. The two handles are preferably arranged on both sides of the weapon barrel. They should be installed at least at a normal height for an operator. Alternatively, adjustment can be provided. The clamping and releasing of the annular pressure plate is accomplished via the handle or handles. On the one hand, this can be achieved using hydraulics with appropriate hydraulic lines or Bowden cables. The barrel weapon can also be brought into a transport position via the movable ball, but the barrel can be brought closer to the base plate.

The ball can also be detached from the base plate. To do this, it can be latched and notched into the base plate. The gun barrel is in this way denplatte separable from the Bo. In this context, it can also be provided that the hydraulic lines or the Bowden cables have an interface, in particular when the pressure plate is part of the base plate or the ball bearing. These interfaces can be omitted if the pressure plate, like the bullet, can be separated from the base plate with the gun barrel.

Since the assembly of the ball on or in the base plate is preferably tool-free, there is no need to carry tools.

To pick up and carry the gun, at least one transport handle, preferably two transport handles, can be attached to the base plate. Alternatives for transportation are known.

The use of a simple plate is preferred as the base plate. This should then be able to be processed by machining. A CFK (carbon fiber reinforced plastic), for example carbon, can be used as the material. The base plate can have any geometry (shape). Oval, rectangular, V-shaped, triangular and other floor panels are conceivable. Below the base plate, this should have at least one claw or at least one spike. The number of spikes can also be made dependent on the shape of the base plate. In the case of a rectangular shape, four spikes are preferable in the respective corner, in the case of a triangular shape at least three.

The spikes or claws can in turn be interchangeable. It is possible to replace a defective mandrel with a new one. However, it is also possible to exchange mandrels for a soft surface with feet for a hard surface. These feet for a hard surface are characterized by the fact that they do not have a point but rather a larger footprint. These feet preferably have a non-slip surface on their standing surface.

A barrel weapon is proposed with a base plate, a ball bearing inserted in the base plate and a weapon barrel having a ball at the end, the ball being rotatably mounted in the ball bearing. The barrel weapon is characterized by the fact that the ball can be fixed in the ball bearing. The fixing, ie the fixing of the ball in the ball bearing, takes place preferably via a pressure plate which is preferably spring-loaded. The spring force acting on the pressure plate must be able to hold the weapon barrel via the ball at the end at the set height even when a shot is fired. The pressure plate is also preferably ring-shaped. At least one tool is provided that can loosen the fixation of the ball in the ball bearing so that the ball can be rotated in the ball bearing. So that the vertical alignment of the weapon barrel can be carried out during the lifting of the fixation of the ball, it is provided that the at least one auxiliary means is attached to the weapon barrel. As a result, aids and weapon barrel can be actuated and moved simultaneously by an operator.

This structural design means that additional support and height direction of the weapon barrel can be dispensed with. These functions are implemented using the clampable ball.

The invention is explained in more detail using an exemplary embodiment with a drawing. It shows: FIG. 1 a slightly perspective illustration of a barrel weapon according to the invention,

FIG. 2 is a top view illustration from FIG. 1 from the rear,

FIG. 3 is a top view illustration from FIG. 1 from the front.

1 with a barrel weapon, for example a mortar or a mortar weapon. The barrel weapon 1 has a base plate 2. A ball bearing 8 is tied into the base plate 2 and integrated into it. The barrel weapon 1 also comprises at least one weapon barrel 4. The weapon barrel 4 has an opening 5 at the front end. At the rear end 6, the weapon tube 4 is completed by a ball 7. It should be noted that a large ball has a greater torque than a smaller ball. The ball 7 is suitable for being supported in the ball bearing 8. Ball bearing 8 and ball 7 have mutually adapted diameters. In the case of a barrel weapon 1 with a caliber of 80 mm, the diameter of the ball 7 can be 180 mm, for example. The ball 7 is a 3-axis adjustment ball.

The ball 7 can be clamped in the ball bearing 8. This is preferably done via at least one spring (not shown in detail) and a pressure plate 9. This is preferably designed as a ring, so that the ball 7 is partially covered by this ring. The preferably ring-shaped pressure plate 9 is pressed onto the ball 7 via the at least one spring. This creates a frictional connection between the pressure plate 9 and the ball 7. Five feathers are preferred. The spring force acting on the pressure plate 9 is to be designed in such a way that the weapon barrel 4 can be held at the set height via the ball 7 even when a shot is fired.

The shape of the base plate 2 can be freely selected. In the present embodiment, the base plate 2 has an approximately triangular shape. The shape A mandrel 13 is attached in each of the corners 10, 11, 12. These mandrels 13 are preferably exchangeable and can therefore also be exchanged. It is irrelevant whether these spikes 13 are below the base plate 2 are firmly attached or are guided through holes 14, 15, 16 in the base plate. To snap into the bores 14, 15, 16, the mandrels 13 can then each have a groove on the circumference (not shown in detail). This should be designed so that the base plate 2 or the edge of the bore 14, 15, 16 can engage in this groove. In the structural design of this connection between the mandrels 13 and the base plate 2, the load when a shot is fired must be taken into account. The mandrels 13 can be used for the application fail on a soft underground.

There is also the possibility of attaching a type of feet 17 to the base plate 2 instead of the mandrels 13. Similar to the mandrels 13, these can be attached to the base plate 2, but can also be inserted into bores 14, 15, 16. The feet 17 differ from the domes 13 in that they for their part do not have a point, but are preferably flattened. The lower surface 18 of the feet 17 can preferably be provided with a non-slip material (FIG. 2). This can be a rubber. Roughened surfaces are also conceivable. The material can also be shock absorbing. Alternatively, a shock-absorbing layer can also be provided on the surface 18 (not shown in more detail). The exchange of the mandrels 13 for the feet 17 enables the gun 1 to be used even on hard ground. The exchange of the feet 17 for mandrels 13 enables use on soft ground.

To the weapon tube 4 a means 30 for clamping the ball 7 in the ball bearing 8 in the Bo denplatte 2 is attached. In the present embodiment, these are two handles 19, 20. The handles 19, 20 are functionally connected to the pressure plate 9 via a line 21, 22 each. These lines can be hydraulic lines or Bowden cables, etc. The means 30 can also receive a display 31 for coordinates in 3 axes. With the aid of this display 31, the alignment of the weapon tube 4 can be determined or displayed. The display 31 thus supports the leveling of the weapon tube 4.

The ball 7 can be separated from the base plate 2. The weapon barrel 4 can thus be separated from the base plate 2, in particular for transport. But a simple exchange of the weapon barrel 4 for another is possible as a result. To simplify the transport or the exchange, interfaces are provided on or in the base plate 2 which enable the lines 21, 22 between the base plate 2 and the means 30 to be separated (not shown in detail).

The base plate 2 can have at least one handle 23, 24. This handle 23, 24 enables the gun 1 or the base plate 2 to be carried and carried by itself. The leveling of the barrel weapon 1 is as follows:

The barrel weapon 1 is brought into a functional position for use, for example, from a transport position (not shown in detail). If the weapon barrel 4 is separated from the base plate 2, the weapon barrel 4 with the ball 7 at the end is in the ball bearing 8 of the base plate

2 indented, i.e. latched into this. The clamping between the pressure plate 9 and the ball 7 is released in that the pressure plate 9 is raised against the spring force which acts on the pressure plate 9. The lifting takes place by actuating the handles 19, 20 and, associated with this, actuating the hydraulics or the Bowden cables. These are operated until the weapon barrel 4 has assumed a desired position. In this position, the barrel weapon 1 can be loaded with ammunition (not shown in detail), for example a grenade. Loading in a different position is also conceivable and not excluded.

To aim the weapon tube 4, the handles 19, 20 are then actuated again, whereby the clamping between the pressure plate 9 and the ball 7 is canceled. As a result, the ball 7 can now move freely again in the ball bearing 8 of the base plate 2. The handles 19, 20 remain actuated until the vertical direction of the weapon nrohrs 4 has ended. The display 31 can be used to support the height direction of the weapon barrel 4.
