Description

The invention relates to a Schränkungsvorrichtung a rifle stock and a rifle with such a Schränkungsvorrichtung.
In particular, in the sports shooter area, it is desirable to have as many customization options of the rifle to the athlete, so this to have the best possible results with an optimally adapted sports equipment.
In the prior art, it is often resorted to complicated and expensive additions or conversions, or the settings are mechanically so complex that a rifle must be put out of hand to make a fixation with several fixing devices to be fixed one after the other possible. As a result, the selected setting is often annoying and the process must be repeated completely.
From the DE 18 54 723 U a sports rifle is known with respect to the run-bearing rifle stock about an upright axis adjustable piston, wherein between the rifle stock and the piston two lockable hinges with upright axles and with an intermediate piece arranged between the joints. The disadvantage here is that considerable forces act on the locking screws and so adjustment or fixation is difficult only possible.

From the FR 679 450 A a rifle stock is known in which a lowering of the shaft relative to the rifle is made possible by two parallel and spaced apart axes in a front and a rear part of the shaft.

The object of the invention is, starting from the FR 679 450 to provide an improved rifle stock and rifle barreling apparatus, with improved handling of the adjustment of the stock.
This object is achieved by a rifling apparatus for a rifle stock according to the features of claim 1 and a rifle according to the features of claim 9.
According to the invention it is provided that a first and a second mutually parallel and mutually movably guided adjustment element is present, which is mounted in each case at its ends on a first and a second bearing block in mutually parallel and mutually spaced bearing axes pivotally, wherein the first bearing block with is connected to or formed by a first part of a shaft, and wherein the second bearing block is connected to or formed by a second part of the shaft, wherein a locking device is provided which blocks a movement of the adjusting elements to each other. This is the most effective way the
Setting the pivoting with fixing only a single fixation allows. This allows the shooter to be set without assistance and without the selected setting being misaligned when setting.

The setting with the inventive Schränkungsvorrichtung is also much more intuitive and the risk of unintentional adjustment is prevented because not several axes must be clamped individually.

Preferably, according to one embodiment of the invention, it is provided that the fixing device is held in a on the second adjusting element in a direction toward the first adjusting out slidably guided in a recess clamping piece. This allows a mechanically particularly effective fixation.

The following is provided according to a further embodiment, that the clamping piece is rotatably configured in the recess about an axis of rotation and the fixing device is supported at a distance from the axis of rotation on the clamping piece. The fact that the clamping piece is guided in a fit and clamped fixed against the opposite adjustment is prevented by the friction force occurring a relative movement of the adjusting elements to each other. Due to the decentralized mounting of the fixing device, a spinning of the clamping piece is prevented during tightening.

An optimal adaptation is achieved by the fact that the fixing device is held on the first adjusting element in a slot along the course of the first adjusting element.

A stable mechanical design is achieved by the advantage that the adjusting elements are plate-shaped.

A particularly effective embodiment of the invention provides that the fixing device is formed by a screw whose screw head is guided in a slot formed over the slot.

An embodiment of the invention provides that the shank is the forearm of a rifle.

A further embodiment of the invention provides that the shank is the buttstock of a rifle.

According to a second aspect of the invention, there is proposed a rifle with a split shaft, which is designed so that between the first part and the second part a Schränkungsvorrichtung according to one of claims 1 to 8 is present.

Further advantageous embodiments will become apparent from the other dependent claims or their possible sub-combinations.

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

In Fig. 1 shows a view of an exemplary embodiment of a Schränkungsvorrichtung 1 in a straight, not entangled position 1 shown. A first 31 and a second 32 parallel to each other arranged plate-shaped adjusting member which is pivotally mounted at its ends 31a and 32a and 31b and 32b at a first 41 and a second bearing block 42 in mutually parallel bearing axes 41a, 41b and 42a, 42b. As a result, a pivoting of the bearing blocks 41 and 42 as in 3 and 4 shown, enabled. The fixing of the adjusting elements 31 and 32 to each other and thus the setting of the setting device 1 takes place by means of a fixing device 5, which blocks a movement of the adjusting elements 31, 32 to each other.

As in the Fig. 1 and 2 and the sectional drawing Fig. 5 shown, the fixing device 5 is formed in the example shown in the form of a screw, the screw head 54 is guided in a formed over the slot 53 groove 55.

The fixing device 5 is held in a form on the first adjusting element 31 in a direction towards the second adjusting member 32 slidably guided in a recess 51 clamping piece 52 in positive engagement in a thread. The clamping piece 52 is in the recess 51 in the adjustment 31st rotatably configured about an axis of rotation and the fixing device 5 is spaced from the axis of rotation 56 on the clamping piece 52 is supported. This causes that when tightening the screw 5, the clamping piece 52 can not rotate.

The fixing device 5 is held on the first adjustment member 31 in a slot 53 along the course of the first adjustment member 31 held in positive engagement.

The effect of the positive connection of the clamping piece 52 in the recess 51 can be well after comparing the two Schnittdarstellugnen after FIGS. 5 and 6 see in comparison. By means of the wrench achieved frictional engagement of the clamping piece 52 against the adjusting member 31, the device is securely locked by the positive connection of the clamping piece 52 in the recess 51 of the second adjustment member 32.

Fig. 7 shows a schematic partial view of a Schränkungsvorrichtung 1 between parts 21 and 22 of a butt shaft 24 of a rifle 6. The first 41 and second bearing block 42 are connected to the first part 21 and second part 22 of the shaft 2 and 24, respectively. The bearing blocks can also be formed by these parts themselves.

In Fig. 8 is a view from the other side of the rifle 6 with a view of the clamping piece 52 shown.

The Fig. 9 to 11 show possible settings of the setting device 1 with corresponding pivoting of the rear part 22 of the butt shaft 24 against the front part 21 of the butt shaft 24th

In Fig. 12 is shown in a schematic side view of a variant in which the Schränkungsvorrichtung 1 according to the invention between parts 21 and 22 of a forearm 23 of a rifle 6 is installed.

Fig. 13 shows a view of the rifle Fig. 12 from underneath. By the U-shaped recess 25, the fixing device 5 of the setting device 1 is easily accessible with a tool. When desired height adjustment by pivoting the lower part 22 of the forearm 23, the determination can be done easily by tightening the fixing device 5. Fig. 14 shows this by way of example.
