    专利说明:

    The present invention relates to a stock for a handgun, comprising a pistol grip and an adjoining stock piston, an essentially U-shaped recess for thumb engagement being formed between the pistol grip and the stock piston.
    So-called perforated shafts have been established on the hunting gun market for some time, which have a distinct pistol grip with a very steep grip angle and a particularly deep recess for the thumb or palm rest in order to be able to ergonomically encompass the pistol grip. However, the deep U-shaped recess weakens the shaft and leads to a significant bending moment in the shaft area below the recess during recoil, which is a problem especially with plastic shafts.
    It has therefore already been proposed to bridge the U-shaped recess for stiffening by means of a strut on the top. However, such a strut is extremely unfavorable for a weapon with a repeating breech, because the strut is an extremely obstacle to a smooth hand movement of the shooter during the repeating process.
    The aim of the invention is to create a stable, strut-free punch shaft.

    This aim is achieved with a stock of the type mentioned in the introduction, which is characterized according to the invention in that a carrier is inserted into the pistol grip, which at its upper end provides a support surface for a recoil-carrying assembly of the weapon, a tension rod on the carrier attacks which runs in the shaft under the U-shaped recess and is tensioned against a shoulder of the shaft piston.
    According to the invention, the recoil force of the firing system of the weapon is thus first transferred to the carrier in the pistol grip and from there passed over the pull rod under the recess and into the stock piston. As a result, the shaft is stiffened around the recess without the need for an interfering strut. The tensile stress via the tension rod ensures a gap-free contact of the wearer in the shaft, which compensates for manufacturing tolerances and offers dynamic stability.
    The construction according to the invention is particularly suitable for the construction of shafts made of wood or plastic, the carrier being made of a material which is more resistant to bending than the pistol grip and shaft piston, in particular of metal. The carrier can be made of high-strength and / or stainless steel, for example, or of aluminum.
    The pistol grip preferably has an inner run-up surface against which the carrier is pulled by means of the tension rod, which gives good force transmission from the carrier into the pistol grip er3 / 21. It is particularly advantageous if the ramp surface runs at an obtuse angle to the tension rod.
    To stiffen the pistol grip and at the same time save weight, the run-up surface can be formed, for example, by the end faces of a plurality of parallel inner longitudinal ribs of the pistol grip. The run-up surface or the inner rib sides thus offer an inner bevel, which derive the recoil forces absorbed by the carrier at its upper end both downwards and in the direction of the tension rod.
    The downward force component of the carrier may e.g. can be intercepted by the fact that it is supported downwards on an inner shoulder of the pistol grip, or simply by the fact that the tension rod connected to the carrier is supported downwards in the region below the U-shaped recess in the shaft. The latter variant has the advantage of simpler manufacture of the barrel without undercuts on the inside of the pistol grip.
    According to a further preferred feature of the invention, a force transmission plate is provided between the carrier and the lower rear inner peripheral region of the pistol grip. As a result, the recoil forces occurring there can be spread over a large area into a lower, e.g. thick-walled, area of the pistol grip can be derived.
    The support surface of the carrier for the recoil-guiding assembly can simply be a vertical front contact surface of the / 21
    Be wearer. However, the support surface is preferably designed as an L-shaped receptacle in the upper end of the carrier, so that it supports the recoil-guiding assembly both towards the rear and downwards.
    It is particularly favorable if the support surface can be screwed to the assembly. This results in a rigid coupling between assembly and carrier, which also fixes the carrier against a downward movement in the pistol grip.
    The tension rod can engage the carrier in any manner known in the art, for example in the manner of a hook. The tension rod is preferably screwed to the carrier, particularly preferably screwed into the latter. This results in a rigid coupling between the carrier and the tension rod, which stiffens the shaft even more.
    In a further preferred embodiment of the invention, the shoulder of the shaft piston can be formed by a partition wall of the shaft piston penetrated by the tension rod, against which the tension rod rests with a rear head. The bulkhead stiffens the shaft piston at the same time, especially if it is hollow and made of thin-walled plastic to save weight.
    It is particularly favorable if the bulkhead through the
    Bottom of a pot-shaped insert is formed, which is inserted into the rear end of the shaft piston. The pot-like insert, on the one hand, stiffens the shaft piston and, on the other hand, can be used as storage space that is accessible from the rear of the shaft piston, e.g. to hold a reserve magazine, an interchangeable trigger group, etc. At the same time the head of the tension rod is sunk and protected, but still accessible for operation, e.g. if it is designed as a screw head or nut for tensioning the tension rod.
    A spring assembly is preferably interposed between the head and the bulkhead. Any thermal or relaxation distortion of the shaft can thus be compensated for in order to always keep the tension rod under tension.
    According to a further preferred feature of the invention, the pistol grip can have an exchangeable front part, via which the carrier can be inserted into the pistol grip. On the one hand, this simplifies assembly and, on the other hand, enables individual configurations of the pistol grip with different front parts. For these purposes, the pistol grip can preferably also have an interchangeable grip cap which can be screwed to the lower end of the carrier.
    In order to save weight, the carrier preferably has openings in the manner of a truss.
    The invention is explained below with reference to an embodiment shown in the accompanying drawings. In the drawings:
    Figure 1 shows the shaft of the invention in a perspective view.
    / 21
    FIG. 2 shows the rear part of the shaft from FIG. 1 in a partially cut-away perspective view;
    Figure 3 shows the rear part of the shaft of Figure 1 in section.
    FIG. 4 shows the shaft of FIG. 1 in a sectional view along the section line I-I of FIG. 3; and
    5 shows the shaft of FIG. 1 in a sectional view along the section line II-II of FIG. 3.
    In Fig. 1, a barrel 1 for a handgun (not shown) is shown, for example a hunting rifle, a rifle, a shotgun or the like. The shaft 1 comprises a fore-end 2 and a butt-end 3, whereby the fore-end 2 can be divided into two parts 4, 5 for manufacturing reasons. The butt stock comprises 3 a pistol grip 6 and a shaft piston 7.
    The terms "top," bottom, "front and" rear ("backward) used here refer to the normal position of use of the shaft 1, as shown in FIGS. 1 to 3, in which the front of the shaft 1 on the right, the back of the shaft 1 is shown on the left, the top and the bottom.
    The shaft 1 is made entirely of wood, plastic or the like. manufactured, with the exception of customary cladding or add-on parts, such as a grip plate 8 on the underside of the fore-end 2, a cheek rest or cheek 9 on the top of the shaft piston 7, an exchangeable / 21
    Front part 10 of the pistol grip 6, a grip cap 11 on the underside of the pistol grip 6, a logo carrier 12 of the shaft piston 7, a shoulder cap (not shown) placed on the rear end of the shaft piston 7, etc., some or all of which parts are made from a different material can, e.g. Wood, leather and / or metal.
    The stock 1, more precisely the forearm 2 and the upper region of the pistol grip 6 of the butt stock 3, receives a system bed 13 made of metal, i.e. a kind of housing or base support in which all the components of the weapon that are involved in firing the shot and thus recoil are mounted. These recoil-guiding assemblies are, for example, the barrel with its breech and breech housing (not shown), a knock-off group 14 (FIG. 2) cooperating with the breech, a trigger group 15 interacting with this, a magazine 16 in a magazine shaft 17 of the system bed 13 or the like , The trigger group 15 with bracket 18 and tongue (not shown) can be removable from the discount group 14 or the system bed 13, for example for security purposes or for modular interchangeability. The system bed 13 can also be configured differently for other types of weapons, for example with an integrated breech housing (“upper receiver”) or the like.
    If the shaft 1 is made of several parts, as here consisting of a fore-end 2 with two parts 4, 5 and a buttstock 3, the system bed 13 can be used at the same time for connecting all of these parts 3, 4, 5. For example, the fore-end parts 4, 5 can be screwed to the system bed 13, and the system bed 13 interacts with components of the butt stock 3, which will be explained in more detail below, in order to connect the fore-end 2 and butt stock 3 to one another. Alternatively, it is also possible to form the fore-end 2 and buttstock 3 in one piece, or only part 5 of the fore-end 2 with the buttstock 3.
    The butt stock 3, and here in particular the pistol grip 6 (without front part 10 and without grip cap 11, if these are interchangeable) together with the butt piston 7 (without cheek 9, without logo carrier 12 and without shoulder cap, if these are interchangeable) is preferred - if also not necessarily made in one piece, ie to the rear part of the pistol grip 6, the shaft piston 7 (without cladding and attachment parts) preferably connects in one piece. 2 and 3 show this area in detail.
    As shown in FIGS. 2 and 3, a deep, approximately U-shaped recess 19 is formed between the pistol grip 6 and the shaft piston 7. The recess 19 is designed for the engagement of the thumb and as a support for the ball of the thumb and thus allows the pistol grip 6 to be largely fully encompassed by hand. Due to the deep incision made by the recess 19 between the pistol grip 6 and the barrel piston 7 in the butt stock 3, this area of the butt stock 3 is at / 21 by the recoil of the weapon
    Firing shot claimed on bend. The construction described below serves to increase the strength of this area.
    A carrier 20 is inserted into the pistol grip 6. The carrier 20 is made of a material which is more rigid than the material of the pistol grip 6 and the shaft piston 7, such as high-strength plastic or metal, for example steel or aluminum. The carrier 20 has approximately the shape of a flat, parallelogram-like bolt with openings 21 for saving weight, in the manner of a truss girder.
    A tension rod 22 engages on the carrier 20, which runs behind the recess 3 in the butt stock 3 and is tensioned against a shoulder 23 of the shaft piston 7. The pull rod 22 pulls the carrier 20 backwards and thus biases the pistol grip 6, inside the carrier 20 of which is received, towards the rear towards the shaft piston 7. For this purpose, the pull rod 22 could act as a simple hook on the carrier 20, also in an articulated manner. In the embodiment shown here, however, the pull rod 22 is rigidly coupled to the carrier 20, so that the unit comprising the carrier 20 and the pull rod 22 forms a type of L-shaped insert in the butt stock 3.
    The pull rod 22 is formed in the example shown by a long screw which is screwed into a rear threaded bore 24 of the carrier 20 and is supported with its head 25/21 on the inner shoulder 23, preferably with the interposition of a spring assembly 26, e.g. from disc springs. Such a screw could also be installed in the opposite direction, that is to say, its screw head 25 is supported on the front of the carrier 20, it penetrates the carrier 20 and it is screwed into a threaded bore in the shoulder 23. Alternatively, the pull rod 22 could be a threaded rod, on the rear end of which a nut is formed, which forms the head 25, and / or the pull rod 22 could be made in one piece with the carrier 20.
    For the introduction of force from the carrier 20 into the pistol grip 6, the pistol grip 6 has an inner run-up surface 27 which is specially adapted to the rear of the carrier 20 and against which the pull rod 22 pulls the carrier 20. The run-up surface 27 extends - like the back of the carrier 20 - at an obtuse angle α to the tension rod 22.
    The ramp surface 27 is formed, for example, by the end faces 28 of a plurality of parallel inner longitudinal ribs 29 (FIG. 4) which run from top to bottom in the pistol grip 6. In order to prevent the carrier 20 from sliding down along the run-up surface, the pull rod 22 can optionally be supported downward in the butt stock 3, for example below the U-shaped recess 19 on a shoulder or an inner rib of the butt stock 3.
    The recoil forces from the system bed 13 to the butt stock 3 are transmitted via / 21 via the carrier 20 in the pistol grip 6. For this purpose, the carrier 20 has at its upper end a support surface 30 against which at least one recoil-carrying assembly of the weapon, here the entire system bed 13, can be supported in the recoil direction (in FIGS. 1-5: to the left). If no system bed 13 is used, the recoil-guiding assembly which is supported on the support surface 30 can be, for example, a breech housing, the tee group 14, a fixed breech (e.g. in the case of a barrel rifle), the barrel itself, etc.
    The support surface 30 may be a substantially vertical surface on the front of the carrier 20. Alternatively, the support surface 30 can form an L-shaped receptacle at the upper end of the carrier 20, so that the recoil-carrying assembly, here the system bed 13, can also be supported on the carrier 20 downwards.
    The support surface 30 is optionally screwed to the recoil-guiding assembly, here the system bed 13, see screw 31. At the same time, the carrier 20 is fixed in the pistol grip 6.
    For uniform distribution of the recoil force absorbed by the carrier 20 onto the butt stock 3, a force transmission plate 32, for example made of metal or plastic, can be arranged in the pistol grip 6 in the lower region between the rear inner circumference of the pistol grip 6 and the rear lower end of the carrier 20. The force transmission plate 32 is adapted on the one hand to the shape of the rear inner circumference of the lower region of the pistol grip 6 and on the other hand to the shape of the rear lower end of the carrier 20 in order to dissipate the recoil forces over a large area into a thick-walled region 33 of the pistol grip 6, see Fig. 5.
    The carrier 20 can be used in the pistol grip 6 at the same time to mount the grip cap 11, for example by screwing or bolting it with holes 34 in the lower end of the carrier 20.
    Furthermore, the carrier 20 can also be used for mounting the interchangeable front part 10 of the pistol grip 6. As shown in FIG. 3, the front part 10 can engage with projections 35 in recesses 36 of the carrier 20 and can be locked by means of a spring-loaded pressure piece 37 mounted in the carrier 20, which engages in a corresponding locking recess 38 of the front part 10. The trigger group 15 can additionally lock the front part 10 with its rear edge 39 after it has been inserted into the system bed 13.
    The shoulder 23, on which the tension rod 22 is supported in the butt stock 3, is, for example, an inner shoulder, a cross strut or a partition wall in the interior of the shaft piston 7, against which the head 25 of the tension rod 22 rests via the spring assembly 26. In the example shown, the shoulder 23 or the bulkhead is formed by the bottom of a pot-like insert 40, which is inserted into the rear end of the shaft piston 7 and is supported with its pot edge 41 on the peripheral edge 42/21 of the shaft piston 7, which is open to the rear. The interior 44 of the insert 40 which is accessible from the rear of the shaft piston 7 via the pot opening 43 can be used as storage space, for example for a reserve magazine or the removed trigger group 15. By means of a (not shown) shaft or shoulder cap or one in the opening 43 sealing cap or the like used. the interior 44 can be closed.
    The jaw 9 is mounted interchangeably on the shaft piston 7, for example by engaging at its front end with a projection 45 in an undercut and at its rear end with a spring bolt 46 in a latching opening 47 of the shaft piston 7. The spring bolt 46 can e.g. can be released or unlocked by means of an actuating pin 48 resiliently mounted in the shaft piston 7.
    The invention is not limited to the illustrated embodiments, but encompasses all variants and modifications that fall within the scope of the attached claims.
