Description

[0001] Recoil-damping device for a firearm

[0002] The invention relates to a recoil-damping device for a firearm, in particular for fastening to or in a buttstock of the firearm, preferably a handgun, having a rear part and a front part which are movable relative to one another between a rest position and a damping position against the force of a damping device.

[0003] Devices for dampening the recoil acting on a shooter following the firing of a firearm are known from the prior art. These devices are designed, on the one hand, to dampen the recoil as effectively as possible in order to avoid or at least reduce injuries or discomfort for the shooter, and, on the other hand, to maintain, as far as possible, accurate target acquisition by the shooter before firing a shot and during the firing of a series of shots. For target acquisition, a rigid design of the recoil-dampening device before firing the shot is advantageous.

[0004] US 2002 / 0053156 A1 discloses a firearm with a recoil-damping device and a locking device. The recoil-damping device is arranged between a rear and a front stock part, which are displaceable relative to one another, and has a damping spring which is compressed during recoil. The locking device enables the compression of the recoil-damping device only after a pulse weight accelerated by a shot releases a lock. In this way, unintentional compression of the recoil-damping device before the trigger is pulled, while aiming at a target, is prevented.The disadvantage of this design is the use of the compressible damping spring, which increases the weight of the recoil-damping device, requires a receiving space for the spring, is generally difficult to replace and must be specially designed for suitable damping behavior.

[0005] US 2006 / 0096148 A1 concerns a recoil dampening system for hunting or sporting weapons, comprising a hydraulic dampening device and a locking device that prevents compression of the recoil dampening device before a shot is fired. The recoil dampening device is arranged between a rear stock section made of soft material and a front stock section that can be moved relative to it. The hydraulic dampening device is also disadvantageously heavy, bulky, expensive, prone to failure, and difficult to replace.

[0006] The object of the invention is to create a recoil-damping device as initially stated, which avoids or at least reduces the disadvantages of the prior art. In particular, the recoil-damping device should be lightweight, space-saving, and cost-effective. The device should also be easy to maintain. In particular, the damping effect should be easily adaptable to the shooter's needs.

[0007] This object is achieved by a recoil-damping device according to claim 1. Advantageous embodiments and further developments are specified in the dependent claims.

[0008] According to the invention, the damping device has at least one elastic linear element which is fastened to the rear part and to the front part and is tensioned in the direction of its longitudinal extent, the elastic linear element being more tense between the rear part and the front part in the damping position than in the rest position. The recoil-damping device therefore has a rear part, a front part which can be moved relative to the rear part, and a damping device, the rear part and the front part being connected to one another via the damping device. The rear part and the front part can be moved relative to one another between a rest position and a damping position against the force of the damping device.If the butt section is attached to a rear part of the weapon itself, in particular the stock, which is close to the shooter's shoulder when the firearm is in use, the front section is preferably integrated into a front part of the weapon, in particular the stock, which is further away from the shooter's shoulder when the firearm is in use. On the other hand, the recoil-damping device can also be attached with its front section to the rear part of the stock of the weapon, which is close to the shooter's shoulder when the firearm is in use, so that a firearm can be easily retrofitted with the recoil-damping device.

[0009] In order to achieve the damping effect, the damping device has at least one elastic linear element which is fastened to the rear part and to the front part and is tensioned in the direction of its longitudinal extent. The elastic linear element can already be tensioned in the rest position. The elastic linear element has a longitudinal extent which is considerably greater, for example at least 10 times, preferably at least 30 times, than a transverse extent or thickness measurable perpendicular to the longitudinal extent. In addition, the elastic linear element exhibits no plastic behavior or negligible plastic behavior during operation of the recoil-damping device. In the damping position, the elastic linear element is tensioned more strongly between the rear part and the front part than in the rest position.When the firearm is fired, the resulting recoil moves the front part from its rest position towards the rear part, whereby the elastic linear element is (further) tensioned, i.e. it is subjected to tensile stress, and absorbs recoil energy and in turn dampens the recoil acting on the shooter's shoulder. At the end of the recoil, the front part and the rear part are in the dampening position. Immediately after the end of the recoil, the elastic linear element strives to relax as much as possible and moves the front part away from the rear part into the rest position. If several, for example two, three or four elastic linear elements are provided, in the event of a defect, in particular if one of the elastic linear elements breaks, a correspondingly reduced recoil dampening can still be achieved.

[0010] The recoil-damping device therefore has, among other advantages, that the tensioned elastic linear element does not have to be accommodated in a guide channel due to the tensile stress, unlike pressure springs or compression springs which can deflect sideways under compressive stress. This means that the recoil-damping device can be manufactured more easily and cost-effectively. Since the longitudinal path of the elastic linear element is not tied to a guide channel, the elastic linear element can be laid more flexibly and the space required for the elastic linear element can be reduced. This also makes it easier to remove the elastic linear element from the recoil-damping device and replace it with a similar elastic linear element or with an elastic linear element with different elongation properties.Removal or replacement of the elastic linear element can also be simplified by providing multiple elastic linear elements, since in this case, each individual elastic linear element has a lower tensile stress in the rest position and can therefore be removed from the recoil-damping device with less effort, for example, without tools. In addition to the flexible guide, the recoil-damping device with the tensioned elastic linear element, for example made of rubber, has the advantage of being lighter than compressed steel springs.

[0011] If in the course of the description reference is made to location and direction specifications such as "top", "bottom", "front", "rear" or "side", these specifications relate to the intended use of the recoil dampening device or the firearm. The term "vertical" means in the direction of gravity, from "top" to "bottom", or vice versa. If the recoil dampening device or the firearm is to be used in a different position, the location and direction specifications must be transferred accordingly. The terms rear and rear describe a position on the recoil dampening device or on the firearm which is closer to the shoulder of a shooter firing the firearm than a position described by the terms front or front.

[0012] According to a preferred embodiment of the invention, the rear part and the front part are arranged so as to be displaceable relative to one another, in particular so as to be displaceable relative to one another in a recoil direction. In addition, the rear part and the front part can overlap one another in a side view, i.e. transversely to the recoil direction. The rear part and the front part are preferably sheathed. By displacing the front part with respect to the rear part, injury to the shooter from otherwise rotatable or deflecting components of the firearm is prevented. By displacing it in the recoil direction, the firearm remains aligned with the intended target during and immediately after the recoil movement. In addition, the shooter generally expects the recoil movement in the recoil direction so that the shooter can absorb the dampened recoil force acting on him with as little injury as possible.Preferably, the space between the front part and the rear part is covered with a cover so that the ingress of foreign matter, such as dirt, and injuries to the shooter are prevented during the movement of the front part to the rear part.

[0013] It is particularly advantageous if the damping device has at least one deflection device around which the elastic linear element is deflected, wherein in particular the elastic linear element runs from a first fastening position, at which the elastic linear element is fastened to the rear part, to the deflection device and from the deflection device to a second fastening position, at which the elastic linear element is fastened to the front part. The deflection device enables the first and second fastening positions to be defined more flexibly and allows the use of an elastic linear element with a greater longitudinal extent. Without the deflection device, for example, the first fastening position on the rear part would be arranged in front of the second fastening position on the front part when viewed in the firing direction, i.e. opposite to the recoil direction, in order to tension the elastic linear element during recoil.The deflection device, on the other hand, also enables the first fastening position to be arranged behind the second fastening position when viewed in the firing direction. The elastic linear element is thus preferably deflected from a path substantially in the firing direction to a path substantially in the recoil direction, or vice versa. For the positioning of the elastic linear element, it is particularly advantageous if a plurality of first and / or second fastening positions are provided. If the first and / or second fastening positions are spaced apart from one another in the longitudinal direction of the elastic linear element, elastic linear elements of different lengths can be used in the recoil-damping device.In addition, the tension of the elastic linear element in the rest position and thus the recoil-damping effect can be adapted to the needs of the shooter by attaching the elastic linear element at selected attachment positions.

[0014] A particularly simple embodiment can provide for the deflection device to be a pin with a round outer surface in cross-section or a roller. In this way, the elastic linear element can slide on the round outer surface, in particular also a round section of the outer surface, or roll on the roller without sustaining damage. The pin and / or the roller can have a groove in which the elastic linear element is guided. Preferably, a longitudinal axis of the pin or an axis of rotation of the roller runs essentially perpendicular to the longitudinal extent of the elastic linear element. The pin is generally understood to be a rigid longitudinal body, such as a bolt or a rod.

[0015] If the elastic linear element is designed with two ends, the elastic linear element can be fastened in a first end region, for example with a first end itself, to the rear part and in a second end region, for example with a second end itself, to the front part. For example, the two end regions or the two ends can be fixed to the rear part and to the front part by a clamp connection or a screw connection. The elastic linear element can have a through-opening at at least one end, for example in the form of a loop, through which a pin, a hook or a screw is inserted.

[0016] If, however, the elastic linear element is designed to be self-contained, essentially like an elastic ring, the elastic linear element can be fastened in the tensioned state in a first end region, for example with a first end itself, to the rear part and in a second end region, for example with a second end itself, to the front part. For example, in the tensioned state, the two end regions or the two ends can be fixed by a clamp connection or a screw connection or can be arranged around a pin, a hook or a screw.

[0017] Preferably, an elastic band is provided as the elastic linear element, which preferably has at least one flat surface in cross-section or is circular. The elastic band, for example a rubber band or plastic band, can be produced particularly cost-effectively, in a space-saving manner and with low weight. In addition, the elastic band can be produced with defined stretch properties. If the elastic band has at least one flat surface in cross-section, it can be designed, for example, as a flat band with a rectangular cross-section. In the case of a round, in particular circular, cross-section, the elastic band can be inserted into the recoil-damping device particularly easily, without having to take account of any twisting of the elastic band about a longitudinal axis thereof.

[0018] According to a further embodiment, it can be provided that a locking device acting between the rear part and the front part is provided, which in a locked position blocks a relative movement between the rear part and the front part and in a released position allows a relative movement between the rear part and the front part, wherein a trigger element which can be activated by means of a shock pulse is provided, which in a holding position holds the locking device in the locked position and in an active position releases the locking device into the release position, wherein the trigger element is designed to be pivotable about a trigger element pivot axis as a result of the shock pulse and at least part of the locking device is designed to be pivotable about a locking device pivot axis as a result of the shock pulse. The locking device can thus block or allow the relative movement between the rear part and the front part.Furthermore, the trigger element can hold the locking device in the locked position while a target is being aimed at and only allow the locking device to move into the release position after a shot has been fired. For this purpose, the trigger element can, triggered by a shock impulse, i.e. in particular by the recoil of the fired firearm, automatically pivot about the trigger element pivot axis and thus move from the holding position to the active position. Triggered by the transition of the trigger element to the active position and thus also as a result of the shock impulse, at least part of the locking device can pivot about the locking device pivot axis from the locked position to the release position. Designing the trigger element in this way as a pivoting element ensures a reliable and comparatively rapid transition from the holding position to the active position.Because the trigger element and at least part of the locking device are mounted so that they can pivot smoothly and overcome only minimal frictional resistance, a reliable blocking and release of the relative movement between the rear part and the front part is achieved.

[0019] In order for the trigger element to move automatically from the holding position to the active position as a result of the shock impulse, in particular as a result of the recoil caused by the shot, it is advantageous if the trigger element has different masses above and below the trigger element pivot axis. For example, the trigger element above / below the trigger element pivot axis can have a higher mass than the opposite one below / above the trigger element pivot axis. In particular, the trigger element above and below the trigger element pivot axis can have different moments of inertia. Due to the different masses of the parts of the trigger element arranged above and below the trigger element pivot axis, the more inert part carries out a delayed movement in the recoil direction as a result of the shock impulse, whereby the trigger element pivots about the trigger element pivot axis.In particular, the more inert portion tends to maintain its position relative to a fixed reference point external to the firearm immediately after firing, while the rest of the firearm moves abruptly toward the shooter as a result of the firing. The weight of the trigger element, or rather the portion located above and below the trigger element pivot axis, is advantageously selected to be sufficiently large to reliably overcome any frictional resistance, however slight, that counteracts the movement of the trigger element.

[0020] Furthermore, it can be provided that the locking device has a receiving element, in particular a recess in the front part / rear part, and a pivot arm which engages in the receiving element in the locked position and is mounted on the rear part / front part so as to be pivotable about the locking device pivot axis, and which is supported on the triggering element in the locked position. Preferably, the receiving element is displaceable in relation to the pivot arm in the active position of the triggering element, while the receiving element is held in a fixed position by the pivot arm in the holding position of the triggering element. The receiving element, which can be designed as a recess, depression, projection or similar, is shaped to achieve a release of the pivot arm from engagement with the receiving element when the triggering element moves from the holding position into the active position, in particular as a result of the shock pulse.Preferably, the receiving element has an inclined contact surface for engagement with the pivot arm, so that when the pivot arm is no longer held in the locked position by the trigger element, the latter moves into the release position due to the recoil and the resulting displacement of the inclined contact surface relative to the pivot arm. The locking device can also be constructed such that the pivot arm is released from engagement with the receiving element by gravity when it is no longer held in the locked position by the trigger element.

[0021] For a particularly low-friction transition from the locked position to the release position and back, it is advantageous if the pivot arm, preferably at its end facing the receiving element, has a pivot arm roller or a pivot arm ball, which engages with the receiving element in the locked position. By means of the pivot arm roller or pivot arm ball, the pivot arm can roll on those surfaces with which it comes into engagement during the relative movement between the rear part and front part, in particular on the receiving element. For a particularly low-friction transition from the locked position to the release position and back, it is also advantageous if the release element has a release element roller or a release element ball, on which the pivot arm, in particular the pivot arm roller or pivot arm ball, is supported in the locked position.

[0022] In order to avoid undesired relative movement between the front and rear parts before a shot is fired, in particular when aiming at a target, it is advantageous if the trigger element is pretensioned into the holding position by means of a biasing element. The locking device is thereby reliably held in the locked position even when the firearm is moved in accordance with normal use. The biasing element can be a spring element. As an alternative to a spring element, the trigger element could be pretensioned into the holding position by means of a magnetic device. For this purpose, a first magnetic element could be arranged on the trigger element and a second magnetic element with the same or opposite polarity could be arranged close to the first magnetic element and external to the trigger element.

[0023] To ensure that the swivel arm automatically pivots back from the release position to the locked position after recoil dampening, it can be provided that the swivel arm is preloaded into the locked position by means of an additional preload element. The additional preload element can be, for example, a spring element or a magnetic device. Alternatively or additionally, the swivel arm can be pivoted back into the locked position by the trigger element when the trigger element is preloaded into the holding position.

[0024] If, in the release element's holding position, the release element's pivot axis, a first rotational axis of the pivot arm roller or pivot arm ball, and a second rotational axis of the release element roller or ball are aligned, the pivot arm is reliably held in the locked position. Furthermore, the transition from the locked position to the release position can be achieved with minimal force, since the pivotally mounted rollers or balls roll against each other as a result of the impact impulse.

[0037] It should be noted that Figures 1 to 8 are not necessarily drawn to scale.

[0038] Fig. 1A shows a firearm 2, preferably a handgun 2a, with a free space 26 in a buttstock 3 or stock of the firearm 2, into which free space 26 a recoil-damping device 1, 1a, 1b can be inserted.

[0040] Fig. IC shows the firearm 2 from Fig. 1A in whose buttstock 3 or stock a differently designed recoil-damping device 1, 1b according to the invention is attached.

[0041] Fig. ID shows the recoil-damping device 1, 1b from Fig.

[0042] IC before insertion into the buttstock 3. The recoil-damping device 1, 1b has, in comparison to the recoil-damping device 1, 1a from Fig. 1B, an additional butt plate 27 and a cushion 28.

[0043] Fig. 2 shows a recoil-damping device 1, 1c for a firearm 2, preferably for a handgun 2a, which recoil-damping device 1, 1c is attached, for example, to a buttstock 3 or stock of the firearm 2. For this purpose, the buttstock 3 or stock can be designed with a constant length in the recoil direction RR of the firearm 2, ie, incompressible.

[0044] The recoil-damping device 1, 1a, 1b, 1c can thus be accommodated in a buttstock 3 or, with minor modifications, can be attached to the rear end of a buttstock 3 and is therefore generally referred to below as recoil-damping device 1.

[0045] Fig. 3 schematically shows an embodiment of the recoil-damping device 1 from the side. The recoil-damping device 1 is shown in Fig. 3 in a rest position RS.

[0046] The recoil-damping device 1 has a rear part 4, a front part 5 and a damping device 6. The front part 5 is that part of the recoil-damping device 1 which is further away from the shooter and is preferably non-positively and rigidly connected to the housing of the firearm 2 including the barrel. The rear part 4 is that part of the recoil-damping device 1 which is arranged closer to the shooter and is non-positively and rigidly connected, for example, to the butt plate 27. The rear part 4 and the front part 5 are movable against one another against a force of the damping device 6 between a rest position RS shown in Fig. 3 and a damping position DS shown in Fig. 4. The damping device 6 has at least one elastic linear element 7 which is fastened to the rear part 4 and the front part 5 and is tensioned in the direction of its longitudinal extent LL.In the dampening position DS, the elastic linear element 7 is more strongly tensioned between the rear part 4 and the front part 5 than in the rest position RS. The elastic linear element 7 can therefore absorb at least part of the energy of the recoil resulting from firing a shot by the elastic linear element 7 being (even more strongly) tensioned during the transition from the rest position RS to the dampening position DS. After the recoil has been dampened, the elastic linear element 7 relaxes again, at least partially, and returns the front part 5 to the rest position RS with respect to the rear part 4.

[0047] 3 and 4 also show that the rear part 4 and the front part 5 are arranged so as to be displaceable relative to one another and in particular so as to be displaceable relative to one another in a recoil direction RR. In addition, the rear part 4 and the front part 5 can overlap in a side view, as shown in Figs. 3 and 4. In particular, the rear part 4 and the front part 5 can be designed to slide towards one another during movement. For example, the rear part 4 can be guided in a guide (not shown) in the front part 5. The front part 5 can have bores 8 for fastening on or in the buttstock 3.

[0048] Fig. 3 further shows at least one deflection device 9 of the damping device 6. The deflection device 9 can be a pin 9a with a jacket surface that is round in cross-section or a roller 9b. In the example according to Fig. 3, the elastic linear element 7 is deflected around the deflection device 9. In particular, the elastic linear element 7 can run from a first fastening position 10, which is not visible in Fig. 3 and at which the elastic linear element 7 is fastened to the rear part 4, to the deflection device 9 and from the deflection device 9 to a second fastening position 11, at which the elastic linear element 7 is fastened to the front part 5.

[0049] The elastic linear element 7 shown in Figs. 3 and 4 can be designed with two individual ends 12a, 12b (see Fig. 7) or it can be designed to be self-contained, like an elastic ring (see Fig. 8). In an embodiment not shown, the elastic linear element 7 can be designed as a tension spring. In the embodiment according to Figs. 3 and 4, however, an elastic band 7a is provided as the elastic linear element 7, which in cross-section preferably has at least one flat surface or is circular.

[0050] The at least one elastic linear element 7 in Fig. 3 can be formed by a single elastic linear element 7, which is arranged multiple times, for example three times, in loops between the rear part 4 and the front part 5. For this purpose, the single elastic linear element 7 can be looped around a plurality of first fastening positions 10, around the deflection device 9 and around a plurality of second fastening positions 11. Alternatively, the at least one elastic linear element 7 can be formed by a plurality of individual elastic linear elements 7, which are each fastened to a first fastening position 10 and to a second fastening position 11.

[0051] The examples shown in Fig. 5 and 6 show a locking device 13 acting between the rear part 4 and the front part 5, which in a locking position SS shown in Fig. 5 blocks a relative movement between the rear part 4 and the front part 5 and in a release position FS shown in Fig. 6 allows a relative movement between the rear part 4 and the front part 5. For this purpose, a trigger element which can be activated by means of a shock pulse

[0052] 14 may be provided, which, in a holding position HS shown in Fig. 5, holds the locking device 13 in the locking position SS and, in an active position AS shown in Fig. 6, releases the locking device 13 into the release position FS. Preferably, the trigger element 14 is designed to be pivotable about a trigger element pivot axis 15 as a result of a shock impulse, i.e., the recoil of the firearm 2, and at least a portion of the locking device 13 is designed to be pivotable about a locking device pivot axis 16 as a result of the recoil. So that the trigger element 14 can pivot reliably as a result of the recoil, the trigger element 14 preferably has different masses above and below the trigger element pivot axis 15. In the example shown, the trigger element 14 has a greater mass above the trigger element pivot axis 15 than below the trigger element pivot axis

[0053] 15 . In the event of recoil, the trigger element 14 therefore pivots with a delay relative to the rest of the firearm 2 .

[0054] 5 and 6 further show that the locking device 13 has a receiving element 17, in particular a recess 17a, in the front part 5 and a pivot arm 18 which, in the locking position SS shown in Fig. 5, engages in the receiving element 17 and is mounted on the rear part 4 so as to be pivotable about the locking device pivot axis 16. The pivot arm 18 is supported in the locking position SS on the trigger element 14 and is thus prevented from pivoting out of engagement with the receiving element 17. In the example shown, the pivot arm 18 has, preferably at its end facing the receiving element 14 or at its end facing away from the locking device pivot axis 16, a pivot arm roller 19 or a pivot arm ball 20, which in the position shown in Fig. 5 engages in the receiving element 17 in the locking position SS shown.In addition, the trigger element 14 preferably has a trigger element roller 21 or a trigger element ball 22, on which the pivot arm 18, in particular the pivot arm roller 19 or pivot arm ball 20, is supported in the locked position SS. The trigger element 14 is preferably preloaded into the holding position HS by means of a preloading element 23. The example according to Fig.

[0055] 5 further shows that in the holding position HS of the trigger element 14, the trigger element pivot axis 15, a first rotation axis 24 of the pivot arm roller 19 or the pivot arm ball 20 and a second rotation axis 25 of the trigger element roller 21 or the trigger element ball 22 are arranged in a line.

[0056] Before a shot is fired, the rear part 4 and the front part 5 are spaced apart from one another because the elastic linear element 7 pulls the front part 5 forwards into the rest position RS, see Fig. 3. The trigger element 14 is in the holding position HS, in which the trigger element 14 holds the locking device 13 in the locked position SS. By supporting the pivot arm 18, the trigger element 14 prevents the pivot arm 18 from pivoting out of the locked position SS into the release position FS. In the locked position SS, the pivot arm 18 mounted on the rear part 4 engages the receiving element 17 provided in the front part 5 and thus prevents movement of the front part 5 in the direction of the rear part 4, see Fig. 5.

[0057] When the firearm 2 is fired, the resulting recoil of the firearm 2 against the shoulder of a shooter (not shown) pushes the firearm 2 backwards towards the shooter, however the trigger element 14 pivots with a slight delay due to its comparatively large mass above the trigger element pivot axis 15. Therefore the pivot arm 18 is no longer supported by the trigger element 14 and can emerge from the receiving element 17 due to the backward movement of the latter, in particular roll out, and pivot into the release position FS, see Fig. 6. This releases the backward movement of the front part 5 against the rear part 4 and the elastic linear element 7 is tensioned, or at least tensioned more strongly, whereby it absorbs at least part of the recoil energy and relieves the shooter's shoulder.The recoil-damping device 1 thus moves from the rest position RS into the damping position DS, see Fig. 4. In the damping position DS, the backward movement of the front part 5 against the rear part 4 is finished. The elastic linear element 7 now pulls the front part 5 away from the rear part 4 in the firing direction SR. Preferably, the pivot arm 18 is pre-tensioned into the locked position SS and / or the trigger element 14 resting thereon is pre-tensioned into the holding position HS, so that the pivot arm 18 pivots back into the receiving element 17 as soon as the front part 5 has been moved far enough forward by the elastic linear element 7. Thereupon, or essentially at the same time, the trigger element 14 also pivots back into the holding position HS, in which it once again holds the pivot arm 18 in the locked position SS, see Fig. 5.Thus, the recoil-damping device 1 has returned to the rest position RS, in which the shooter can again aim at his target without compressing the recoil-damping device 1 and thereby impairing the aiming.
