Abstract

A gun barrel (3) with a pistol grip (2), the pistol grip (2) being connected to the rifle stock (3) by means of a ball joint (4) such that the pistol grip (2) is rotatable about the vertical axis (R) and beyond the center of the ball in all spatial directions (x, y) is pivotable, characterized in that the pistol grip (2) has a pan (21) in which the on the rifle stock (3) existing ball head (31) of the ball joint (4) engages positively, wherein a on the pistol grip (2) mounted screw (22) is provided, which engages in the thread (34) of a ball head (31) in a recess (32) mounted ball nut (33), by means of which the pan (21) and thus the pistol grip (2) can be held in a selected position on the ball head (31) of the rifle shaft (3) in frictional connection.

Description

The invention relates to a rifle stock with pistol grip and a rifle with such an arrangement.

From the prior art rifles with pistol grips 2 , as in 3 shown, known for a long time.

Not every shooter is a fixed pistol grip at the predetermined position and orientation of the same relative to the rifle stock, as the physical differences and preferences of attitude are different. To achieve better results, for example, in competitive situations are therefore adjustment options, as in 4 shown, known in such a way that the pistol grip 2 at the rifle stock 3 via a pivot axis 5 is pivotally mounted.

However, professional athletes or precision shooters still do not find this the best solution, as pain or cramping can still occur in the wrist.

From the DE 20 2005 020 116 U1 a fastener for a handle has become known that allows an adjustment of the handle against a rifle stock, wherein a ball head is clamped by means of a screw.

From the DE 10 2004 057 415 A1 a similar arrangement has become known in which a ball nut is pulled against a spherical recess by means of a screw for clamping to clamp a handle on a rifle stock.

A disadvantage of the aforementioned writings here is that the holding forces of such an already known in photo tripod arrangement must be very, so that the screw must be tightened. This has the disadvantage that in this case can be deformed on the one hand, the ball head of the ball joint and on the other by the necessary powerful tightening the screw setting can only be done by grasping and under accidental adjustment.

The object of the invention is to provide an improved rifle stock with pistol grip, which can be adjusted to a desired attitude of a shooter.

This object is achieved by a gun barrel with pistol grip and a rifle with such an arrangement according to the features of claim 1 or 9.

According to the invention, the pistol grip is connected to the rifle shaft by means of a ball joint such that the pistol grip is rotatable about the vertical axis and, moreover, pivotable about the center of the sphere in all spatial directions, the pistol grip having a socket in which the ball head present on the rifle shaft has a positive fit engages, wherein a screw mounted on the pistol grip is provided, which engages in the thread of a spherical nut mounted in a recess ball nut, by means of which the pan and thus the pistol grip on the ball head of the rifle shaft can be held in a selected position in adhesion.

As a result, a perfectly optimal adjustment of the pistol grip on the ergonomically best for the shooter position of the pistol grip against the rifle stock is possible in a particularly effective manner.

The advantage lies in the clamping of the ball nut against the rounded recess on the one hand and on the other in the clamping of the ball head against the ball joint. As a result, the surface of the clamping is maximized and the holding forces that must be applied by the screw can be reduced, which greatly facilitates the handling, since no longer must be tightened so tight, and reduces the wear by deformation.

Advantageously, the ball head is connected to the rifle shaft via a cuboid mounting plate.

In order to enable an even wider setting possibility with the least possible lateral structure is provided that the ball head outside the center of the mounting plate is connected to this particular one piece.

It is advantageous for a variable as possible setting provided that the cuboid mounting plate is connected to the rifle stock in threaded holes or slidably provided in a provided on the underside of the rifle shaft rail with nuts by means of screws.

In order to allow the shooter a comfortable embracing the pistol grip is provided according to a development of the invention that the pistol grip is ergonomically shaped according to a hand enclosing the handle.

Advantageously, the ball joint is arranged on the buttstock of the rifle stock.

In order to provide a dismountability of the rifle is after a development of the invention provided that the buttstock is connected by means of a detachable connection with the fore-end.

According to a further aspect of the invention, a rifle with a rifle stock according to one of claims 1 to 7 is proposed.

The invention will be further explained with reference to the drawings. In detail, the schematic representation in:

The same reference numerals in the figures designate the same or equivalent elements.

In 1 is a rifle according to the invention 1 with a rifle stock 3 with inventively pivotable pistol grip 2 shown. 2 shows an enlarged view from another angle.

The pistol grip 2 is at the gun shaft 3 by means of a ball joint 4 connected so that the pistol grip 2 about the vertical axis R rotatable and beyond the ball center in all spatial directions x, y is pivotable. The ball joint 4 is at the buttstock 38 of the gun shaft 3 arranged.

The pistol grip 2 is ergonomically shaped according to a hand enclosing the handle.

5 shows the ball joint 4 with disassembled pistol grip 2 , where the ball head 31 is apparent.

In 6 is a schematic cross section through the ball joint 4 mounted pistol grip 2 shown, with the pistol grip 2 a pan 21 in which the on the rifle stock 3 existing ball head 31 of the ball joint 4 positively engages.

One on the pistol grip 2 mounted screw 22 engages in the thread 34 one in the ball head 31 in a recess 32 mounted ball nut 33 one. This can be the pan 21 and with it the pistol grip 2 on the ball head 31 of the gun shaft 3 in a locked position in a selected position, pivoted about the axes x and y and rotated around the high-altitude R (see also 8th , with all panning, y and rotation possibilities R), can be kept.

The ball head 31 however, is on the rifle stock 3 via a mounting plate 35 (please refer 5 ) connected in the 7 to 10 is explained in more detail.

By tightening the retaining screw 22 be ball 31 and ball socket 21 fixed. The mounting plate 35 is advantageous displaced on the rifle stock 3 screwed. For this purpose, the mounting plate 35 at the rifle stock 3 in threaded holes or slidable in one at the bottom of the rifle shaft 3 provided rail with nuts connected by screws.

To achieve a large displacement with a compact size, the ball head 31 of the ball joint off-center on the mounting plate 35 arranged as in 9 seen. By a 180 ° rotation of the mounting plate 35 at the rifle stock 3 also results in a doubling of the displacement, as in 10 illustrated in a plan view.

The cuboid mounting plate in the example 35 has long holes 39 by means of which these at the rifle shaft through through the slots 39 reaching fastening screws laterally from the axis of the barrel 11 offset adjustable fixable.

11 Finally, shows a gun according to the invention 1 with pistol grip described above 2 in disassembled condition with barrel 11 , System 12 , Before the- 37 and butt shaft 38 , where the buttstock 38 by means of a detachable connection 13 with the forend 37 connected is. The pistol grip 2 is at the buttstock 38 over the means of the mounting plate 35 mount the ball head 31 with the pan 21 arranged.
