Definitions

  • 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.
  • a locking ring is provided.
  • 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.
  • a barrel weapon in particular a mortar or howitzer, with at least one weapon barrel and a base plate
  • 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.
  • the base plate has two ball sockets, one on the first side and another on the second side.
  • 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.
  • 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.
  • 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 object of the invention is to propose a simple and improved leveling of a mortar weapon or a barrel weapon.
  • 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.
  • 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.
  • 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.
  • 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.
  • the ball can be fixed again and the frictional connection re-established.
  • 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.
  • 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.
  • 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.
  • 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.
  • the at least one auxiliary means is attached to the weapon barrel.
  • 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 barrel weapon 1 also comprises at least one weapon barrel 4.
  • the weapon barrel 4 has an opening 5 at the front end.
  • the weapon tube 4 is completed by a ball 7.
  • 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.
  • 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.

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.
