Description

The present invention relates to a barrel holder for a firearm, in particular a straight-action repeating rifle with a closure box whose end region directed towards a barrel of the firearm as a receiving region formed substantially parallel to each other, downwardly projecting, each having an aperture extensions comprising pipe clamp for releasably fixable barrel, is formed and a releasably secured to the closure box forearm.

In some firearms, especially hunting weapons, such as straight-action repeating rifles, the barrel is often interchangeable with the housing. In such determinations, it is essential that on the one hand the barrel is held securely and substantially immovable and on the other hand ensures that the holder is not subjected to uneven tension or stress by the holder, whereby not only the barrel is warped, but a shot accuracy can not be guaranteed.

Moreover, in modern hunting weapons, the aiming optics is usually fixed to the barrel, so that a strained or unevenly loaded barrel and especially a warped barrel with the associated target optics no longer match and thus the target and shooting accuracy is greatly impaired. Furthermore, in such a case after the replacement of the barrel and a new determination of a new run, the target optics must be recalibrated to the barrel, which is particularly time consuming. As holders for such runs on the one hand, a barrel holder-known, with which a hydraulically acting holding means for holding the barrel is provided on the housing. The disadvantage of such a solution is not only the provision of a hydraulic fluid in the region of the holder, but in particular that for a hydraulic barrel holder corresponding sealing means, such as O-rings and the like. Are required.

Furthermore, the various mechanical runners have become known, such as those from the DE 1 959 748 A1 known barrel holder, wherein the barrel of the rifle is fixed to at least two locations with screws or clamp-like enclosures. By defining the barrel in two places, on the one hand there is a risk that the barrel, as described above, warps, and on the other hand the use of screws is disadvantageous in that they must be tightened very tightly in order to ensure a firm hold of the barrel and in particular to withstand a vibration of the same, which greatly increases the risk of uneven tensions and, moreover, the opening the running bracket is very difficult and in particular without tools seems impossible.

The present invention therefore aims to provide a barrel holder for a firearm, with which both the disadvantages of the hydraulic determination as well as those of the known mechanical specifications should be avoided and with which it is possible in a simple manner, the run safely and reliably connect to the closure box without requiring calibration after the determination of the barrel and without the risk of causing the barrel to warp.

To solve this problem, the barrel holder according to the invention for a firearm is characterized essentially in that the barrel holder as a guided through the openings of the extensions mandrel on each outer side of the extensions a, mounted on the mandrel jaw and a pivotable about the mandrel clamping lever having a clamping device is formed and that on the side facing away from the clamping lever end portion of the mandrel interacting with a stopper clamping screw is provided. The fact that the barrel holder is designed as a guided through the openings of the extensions mandrel and on each outer side of the extensions a jaw mounted on the mandrel and a pivotally articulated around the mandrel on the clamping lever clamping device, it is possible to be determined or clamped barrel uniformly applied to all sides with pressure and thus set completely centric in the receiving area of the lock box. By using only a single such clamp in the manner of a clamp, any distortion of the run or any uneven, applied to the run voltage is avoided. By the holder device in the manner of a pipe clamp by means of a clamping lever can be closed or opened, on the one hand the use of tools such as screwdrivers avoided and on the other hand it is possible to provide a simple manually operable running bracket available, the run of a firearm with a always applied constant pressure, so that further a running mount can be provided, with which it is possible with a simple handle, the run safely and reliably in always the same Position and clamp with the same holding force, so that a firearm with such a clamped barrel after changing the barrel in any case does not need to be readjusted or calibrated. By further provided on the clamping lever facing away from the end portion of the mandrel interacting with a stopper clamping screw, it is further ensured that in a loosening of the clamping lever due to multiple actuation, in turn, a constant pressure or a uniform voltage can be applied to the run in the Clamping screw is tightened accordingly. For this purpose, all technically possible variants of a clamping screw are used, provided that it has a plurality of engagement points for the stopper to allow a fine adjustment of the holding pressure exerted by the barrel holder.

By, as this corresponds to a preferred embodiment of the invention, the barrel holder is formed so that the stopper has a meshing with an external toothing of the clamping screw teeth, it is possible if the pivoting movement of the clamping lever is no longer the sufficient voltage for a secure and reliable clamping or To be able to apply the holder of the barrel, by simple tightening, for example by a single catch of the clamping screw and a renewed meshing of the teeth of the stopper in the external toothing of the clamping screw, readjust the barrel holder so far that by the pivoting movement of the clamping lever always the same voltage or the same Pressure can be applied to the pipe held in the clamp.

By, as this corresponds to a preferred embodiment of the invention, the barrel holder is formed so that the jaws are each formed substantially as a half cylinder and that in each case the curved cylindrical surface on the corresponding extension of the pipe clamp in abutment, we trained by the both sides of the pipe clamp Clamping jaws in each case substantially only along a line exerted a pressure on the extensions of the clamping screw and thus also an uneven pressure distribution, especially in the direction of the depth of a run to be used in the barrel holder with security.

An even further equalization of the pressure and thus an increased accuracy of clamping the barrel is achieved according to the invention in that the curved cylindrical surfaces are formed contoured and in particular have two mutually different radii. With a cylinder surface configured in this way the jaws of the clamping device is particularly ensured that such a clamped barrel exercises no vibration even with a plurality of successively delivered shots and thus the repeatability of the shots can be maximized.

In order to withstand too much pivoting of the clamping lever and thus excessive clamping of the barrel with safety, the barrel holder is developed to the effect that the clamping lever adjacent jaw has a stop. In addition, by providing such a stopper, it is ensured that the fore-end lockable after a successful running lock with the lock box slips smoothly over the run mount and receives it inside the forend, so that inadvertent operation of the run mount during, for example, shooting is also safely arrested ,

Such unintentional actuation of the clamping lever of the barrel holder is in particular also refrained by the fact that, as this corresponds to a development of the invention, an actuating lever is in particular detachably fixed to the clamping lever. By an operating lever is fixed to the clamping lever, on the one hand, the required leverage is provided to manually open and close the barrel holder or to manually clamp or release the barrel, and on the other hand, by, as a preferred embodiment corresponds to such an actuating lever, it can be deducted by releasably fixing the same after actuation of the clamping device of the actuating lever and, for example, inserted into a recess provided for this purpose in the forend, so any unintentional actuation of the clamping lever, in particular because, by hand, the required pivoting force of an example only the same length as the entire run bracket having clamping lever can not be applied can be avoided.

In order to safely withhold any dodging or uneven tightening of a barrel in the barrel holder according to the invention and further to the slot in the capping box as small as possible in the closure box at the end portion of the box box formed of a kind of clip hold, the invention is further developed to the effect that on the mandrel a arranged between the extensions of the clamp with a counter-bearing, on which the free ends of the extensions in Appendix, provided shim is provided. By providing the shim, which is arranged on the mandrel between the extensions of the clamp, on the one hand, the gap in the pipe clamp, in which a running end is to be kept as low as possible and on the other hand, by providing an abutment, the necessary support of the extensions of Pipe clamp and thus the entire barrel mount made available, in particular any lateral deviation and thus warping and uneven holding a run, which would, for example, after an onset of a run a costly recalibration and in particular a reduced shooting accuracy by itself, withholding.

In order to continue to be able to additionally provide a mechanical hold of the forend in the region of the barrel holder, the invention is developed to the effect that two substantially parallel to the jaws and in particular the anvil at least partially comprehensive recordings are provided. By at least partially comprehensive recordings are provided substantially parallel to the jaws and in particular the anvil, on the one hand ensures that the structural design of the barrel holder is as compact as possible and also an outer contour of the barrel holder is provided, which is essentially a cuboid approaches, thereby avoiding unnecessary projections and protrusions, which, for example, could lead to undesirable vibrations or lack of accuracy in an operation, in particular in a repeated operation of the rifle.

If, as this corresponds to a development of the invention, the recordings are fixed to the shim and in particular by means of retaining pins, an exact centric fixing of the recordings is also ensured, so that even a one-sided load on the barrel holder is avoided and thus even after repeated Connecting or releasing the forearm from or with the closure box is an uneven loading of the barrel holder is held back.

In order to ensure a releasable, in particular a repeatedly releasable locking of the forearm with the barrel holder, the invention is so further developed, as in a further development of the invention that in a recess of each receptacle at least one, in particular resiliently mounted, at least one catch having clamping bar is used. By providing a particular resiliently mounted, at least one detent having clamping bar in each recording complementary elements on the forearm can engage in the notches and be released by the resilient storage of the same after a snap by simply manually pressing again from the locking or holding position, so that a secure and reliable and especially simple locking of the forearm with the closure box and In particular, the barrel holder is ensured, with a particularly simple locking of the forearm with the barrel holder can be achieved if, as corresponds to a development of the invention, the clamping bar used in the recording with a complementary trained Vorderschaftwelle is releasably locked. By locking the clamping strips used in the recording with complementary trained Vorderschaftwellen an easily detachable, in particular manually releasable locking of the forearm with the closure box and thus provided with the barrel holder, which can be solved by simply exerting pressure on the clamping strips used in the recording is and thus without any impairment of the barrel holder per se, the closure box can be repeatedly separated from the forend. It is needless to say in this regard that the fore-end, as in the prior art, is usually additionally secured by means of, for example, a screw against unintentional displacement with respect to the closure box and, as is also known, displaceable along the longitudinal direction of the barrel is stored.

For a further increase in shooting accuracy, and in particular to prevent any vibrations of the barrel in the closure box and thus inaccuracy of the aiming, the barrel holder according to the invention is further developed such that the closure box in the region of the tube formed as a receiving area for running with at least two, in particular, three longitudinal grooves is formed. By providing longitudinal grooves in the region of the receiving area formed as a pipe clamp, a full-surface contact of the barrel is kept in the interior of the receiving area, whereby vibrations of the barrel in the receiving area of the lock box are repressed and in particular small pressure fluctuations can be absorbed in the longitudinal grooves.

A particularly efficient recording of such possibly occurring vibrations is achieved in that the longitudinal grooves have the contour of a circle segment.

By providing such a running mount not only an easy-to-use, purely mechanical run holder is provided, but with respect to known barrel holders, which also have mechanical holding elements, the provision of screws, which are consuming mechanically operated, and in addition by providing the stopper-interacting clamping screw corrects each clamping force reduction of the barrel holder by adjusting the clamping screw, thereby providing always uniformly firm clamping of the barrel, and easily and reliably eliminates the reductions in tension usually caused by wear or repeated operation can be provided, so that a repeatedly operable, in practice tests several thousand times without any impairment operable running bracket can be provided.

In detail, a barrel holder for a firearm, generally designated 1, is formed in an end region of a closure box 2 of the firearm directed towards the mouth of a barrel. The barrel holder 1 in this case has directly in the closure box 2 formed a receiving area for a barrel of the firearm, which receiving area is formed substantially as a pipe clamp 3 with two mutually parallel, downwardly projecting, each having an opening projections. From this pipe clamp 3 is in Fig. 1 only the receiving area for the run recognizable, with the extending parallel to each other Extensions due to the arrangement of a schematically designated 4 clamping device for the barrel of the firearm are not visible. For a secure and reliable support or clamping of the barrel of the firearm is for clamping of the barrel in the barrel holder 1, a clamping lever 5, which in the Fig. 1 and Fig. 2 is shown in both the open and closed position, pivoted, whereby the jaws 6, which in turn Fig. 1 are not visible, are pulled towards each other to securely lock the barrel of the firearm in the pipe clamp 3. The jaws 6 are here, as in particular in Fig. 2 can be seen, as well as clamping lever 5 arranged on one and the same mandrel 7, which mandrel 7 further penetrates the extensions of the pipe clamp 3 and thereby compresses the formed in the pipe clamp 3 slot 8 at a pivoting of the clamping lever 5 in the closed position to a minimum, whereby the barrel is securely held in the pipe clamp 3 and the barrel holder 1.

In order to keep the gap 8 in the pipe clamp 3 as small as possible and in particular to hold back as far as possible to any vibration of the barrel in the barrel holder 1, this is an insert sheet 9 protruding into the slot 8 on the mandrel 7 as well as an abutment 10, which is accommodated in the closure box 2 and on which abutment 10, the free ends of the extensions of the pipe clamp 3 in abutment, thereby ensuring adequate support of the pipe clamp 3 and thus warping or vibration of the barrel in the pipe clamp 3 and in the closure box 2 to further reduce provided.

In the representations of Fig. 1 and Fig. 2 is further provided on the clamping lever 5, a releasably fixed actuating lever 11: In the formation of the barrel holder 1 according to Fig. 1 and Fig. 2 is this releasable operating lever 11 after locking the clamping lever 5 in its closed position, which in the Fig. 1 and 2 is shown with each deducted operating lever 11, removed from the clamping lever 5 and inserted, for example, in a designated, not shown receptacle in the forend to be available again for any further required operation at any time.

The jaw 6, on which the clamping lever 5 is hinged or which is adjacent to the clamping lever 5, this is to a horizontal pivoting position of the clamping lever 5 beyond with safety stop, provided with a stop 12, which stop directly to the annular part of Pipe Clamp 3 adjacent is arranged, as this in particular the representation of Fig. 2 is clearly removable.

Finally, the jaws 6, as this particular Fig. 2 can be clearly seen, designed substantially as a half-cylinder 13, wherein in each case the curved cylindrical surface on the corresponding extension of the pipe clamp 3 is in abutment, ie in each case the flat surface of the half-cylinder 13 is directed outwardly and the curved surface of the half-cylinder 13 of the jaw 6 are directed to the extensions of trained as a pipe clamp 3 barrel holder. With such a design, it is possible to exert a uniform pressure on the extensions, wherein the pressure is applied substantially along a line on each side of the extensions, and thus an uneven pressure distribution is repressed. For a further homogenization of the contact pressure of the half-cylinder 13 of the jaws 6 on the extensions of the barrel holder 1 in this case formed as a half-cylinder 13 surfaces are each contoured and in particular have two mutually different radii. With such a configuration, the area or the line in which the half-cylinders 13 are brought into abutment with the extensions of the barrel holder 1 is further reduced or shortened, so that the clamping area ideally approaches a point-like clamping, whereby a Warping or uneven pressurization on the extensions is further reduced.

Finally, in Fig. 1 14 denotes a receptacle in which receptacle 14, for example, complementary to the receptacle 14 formed Vorderschaftwellen are arranged. In a recess of each receptacle 14 is at least one in particular resiliently mounted, at least one detent 15 having clamping bar 16 is used. The clamping bar 16 used in the receptacle 14 is in this case formed with complementary front shafts 17, which are in Fig. 4 are shown, releasably lockable.

On the in Fig. 1 and 2 the clamping lever 5 side facing away from the lock box and in particular the clamping device 4 is in this case an on the clamping lever 5 remote from the end portion of the mandrel 7 is provided with a stopper 18 interacting clamping screw 19, as shown in an enlarged view in FIG Fig. 3 is shown. The clamping screw 19 is in this case formed with an outer toothing 20, which outer toothing 20 with a complementary toothing 21, which on the stopper 18 in particular on the clamping screw 19 side facing the stopper 18 is provided, formed. Through multiple pivoting of the clamping lever 5 between an open and closed position, it can happen over time that the clamping force, which is applied to the substantially the shape of a pipe clamp 3 having bearing bracket 1, decreases, creating a safe and vibration-free mounting of Run a firearm can no longer be guaranteed. In such a case, the clamping screw 19 is rotated by inserting, for example, a Allen key in the recess provided for it in the clockwise direction by one notch, whereby the clamping screw 19 correspondingly shortens the mandrel 7 and the clamping force is restored to the original level. With such a device, it is possible to provide a mechanical run holder available, which can be opened and closed almost any number of times without loss of clamping force.

For a connection of the closure box 2 with a forearm, not shown in the drawing, as has already been stated, on both sides of a support 10 each have a receptacle 14, in which Vorderschaftwellen 17 a example in Fig. 4 shown holding device 22 which is arranged in the forearm, can be used. The holding device 22 is in this case inserted into the forend, that only the fore shafts 17 are arranged projecting in the interior of the forend, so that when pushing the forearm on the closure box 2 of the forend can be brought into engagement with the closure box 2, that the in Fig. 1 shown bearing surfaces 23 can be brought exactly with complementary trained contact surfaces of the forend into abutment, whereby the weapon not only has a reliably clamped barrel, but also releasably locked to the forearm of the same. For a final determination of the forearm this is often set with a known screw.

In the presentation of Fig. 5 another perspective view of the clamping device 4 with the holding device 22 is shown engaged.

Like this in Fig. 5 can be seen, two clamping jaws 6 are arranged on the mandrel 7 so that their semi-cylindrical surfaces 13 are directed in the direction of to be clamped extensions of a substantially the shape of a pipe clamp 3 having clamping device 4 for a run. In a slot 8 between the extensions of the clamping device 4 in this case the shim 9 is inserted to the slot 8 in the clamp 3 as low as possible. Furthermore, in Fig. 5 It can be seen that the abutment 10 is held on the retaining plate 9 and further it is also apparent that for adjusting the clamping force on an actuating lever 11 opposite flat surface of the jaws 6, a clamping screw 19 and a stopper 18 are provided, which as in connection with Fig. 3 described, work. Finally, too Fig. 5 to take the contoured surface of the trained as a half-cylinder 13 jaws 6. Also in the presentation of Fig. 5 a stop 12 is provided to prevent inadvertent too far pivoting of the pivot lever 11 beyond a substantially horizontal position addition.

The locking of the holding device 22 with the clamping device 4 is in the in Fig. 5 variant shown exclusively by a resiliently mounted clamping bar 16, which has at least one provided in a front shaft 17 of the holding device 22 recess catch 15 meshing.

In summary, it should be noted that it is possible with a barrel holder 1 according to the present invention in a safe and reliable manner to clamp the barrel of a firearm purely mechanically, with such a clamping device 4 can not only ensure that the clamping force on the barrel on the Time and also after a variety of operations always the same size can be kept, but by the special geometry of the items and a vibration of the barrel as well as a potential recalibration after exchange of a run is not required.
