    The present invention relates to a housing for a
    Firearm with interchangeable barrel, comprising a socket into which the barrel root of the interchangeable barrel can be inserted in the axial direction, the socket having a slot in the axial direction and a tensioning device for moving the slot from an initial position into a narrowed position.
    Firearms, the housing of which is designed for one
    Interchangeable anchoring barrel are in the field of
    Hunting or sporting weapons and especially used as sniper rifles. Both the socket of the housing and the barrel root must be manufactured with high accuracy requirements. If there is too little play between the two
    Parts of the barrel root would no longer be insertable into the socket of the housing. A large game would have to compensate for the tensioning device by deforming the bushing more, which leads to undesirable tension in the housing and to an increased load on the tensioning device itself, which the entire
    Must have resilience, and overall the precision of
    Anchoring of the barrel root to the housing is impaired.
    The present invention aims to provide an improved housing for a firearm with a change barrel, which is easy to manufacture and despite uncomplicated & VOITH PATENTANWÄLTE PARTNERSHIP · FN 463913A · KOPFGASSE 7 · A-1130 VIENNA · WWW.PATENTE.NET TEL + 43 (1) 8791706FAX +43 (1) 8791707MAIL @ PATENTE ^ NWrIBAN AT102011100003856704BIC GIBAATWWATU71838648 adorned barrel change the barrel change a safe, precise
    Offers seat on the housing.
    This aim is achieved according to the invention with a housing of the type mentioned in the introduction, which is characterized in that the socket in the starting position of the slot, which is not influenced by the tensioning device, for receiving the
    Running root is formed with a press fit and has a spreading device for moving the slot from the initial position into an expanded position.
    The spreading device makes it easier to insert the
    Root of the replacement barrel in the axial direction into the socket essentially by expanding the socket by widening the slot. The accuracy requirement for the production of
    This can reduce the bushing and barrel root. Since in the uninfluenced starting position of the clamping device
    If the barrel root is already received with a press fit in the socket, a high-precision fit of the barrel root in the socket is ensured. In the narrowed position of the
    The barrel root, and thus the replacement barrel, is anchored particularly securely to the housing without the tensioning device having to exert the entire force required for this itself.
    The spreading device can be completely independent of the clamping device. In a preferred embodiment, this has
    Housing a common actuator for the tensioning device and the spreader. Form this way
    3.13
    Clamping device and spreading device are one unit, which facilitates operation and is particularly space and weight-saving. It is particularly preferred if the actuating element has two actuation directions, in one of which the
    Slot from its starting position to its narrowed position and in the other the slot can be moved from its starting position to its expanded position. Clamping device and spreading device can never work against each other: By actuating in one direction, the actuating device becomes a clamping device, by actuating in the other direction it becomes a spreading device and vice versa.
    It is advantageous if the socket has legs formed on both sides of the slot and the clamping device through the
    Leg and at least one clamping screw is formed, which is rotatably mounted with its screw head on one leg and engages with its thread in an internal thread of the other leg, the slot being displaceable from its initial position into its narrowed position by tightening the clamping screw. It is particularly favorable if the
    Spreading device is formed by the legs, the clamping screw and an axial bearing, which axially fixes the clamping screw in said one leg, the slot through
    Loosening the clamping screw from its initial position to its expanded position can be moved. That way they are
    The clamping device and the spreading device each save space and are robust in construction and easy to use. Furthermore, the clamping screw can optionally be the common actuating element mentioned, so that the clamping device and
    Spreading device form a unit, which facilitates operation and is particularly space and weight saving.
    The tensioning device and the spreading device can never work against each other: If the tensioning device is relaxed by loosening the tensioning screw, simply turning the tensioning screw further turns it into the spreading device and vice versa. Since the tensioning device does not have all of it necessary to anchor the barrel in the socket of the housing
    A single clamping screw can be sufficient to anchor the barrel securely to the housing.
    It is advantageous if the thrust bearing by a
    Counterbore is formed with a circumferential groove and a ring received in the circumferential groove, the screw head from
    Ring is axially fixed in the counterbore. In this way, the screw head and thrust bearing are largely protected from environmental influences and do not hinder the use of the firearm. At the same time, the actuation of the tensioning or spreading device is easily possible at any time. The is preferred
    Ring a circlip, a snap ring or a spiral circlip. The snap ring and snap ring are easy to insert and remove, the snap ring being more flexible, while the snap ring provides a more even groove load; on the other hand, the spiral snap ring makes an even smoother contact with the groove, but is
    5/13 more difficult to insert and remove. Depending on the requirements, the most suitable ring can be selected.
    In a particularly preferred embodiment, the
    Socket in one piece with the housing. In this way, a particularly stable fit of the replacement barrel is ensured directly on the housing.
    The invention is explained in more detail below with reference to an embodiment shown in the accompanying drawings. The drawings show:
    Figure 1 shows a portion of a housing according to the invention for a firearm for receiving a barrel root of a replacement barrel in a side view. and
    Fig. 2 shows the housing of Fig. 1 with an inserted root in a cross section along the section line A-A.
    The example of FIGS. 1 and 2 shows a section
    Housing 1 for a firearm. The housing 1 comprises one
    Socket 2, in which the barrel 3 of a replacement barrel for the firearm sits (Fig. 2). The root 3 is in
    Direction of the longitudinal axis 4 of the firearm, which is also the
    Longitudinal axis 4 of the barrel and the housing 1 is in the
    Inserted and anchored in socket 2.
    In the example of Fig. 2 the barrel 3 has a circular outer periphery 5 and the socket 2 has a corresponding, therefore also circular inner periphery 6. It is understood that the socket 2 and the barrel 3 can alternatively have different, mutually corresponding shapes, e.g. ei6 / 13 nen polygonal or oval cross-section, the root 3 could also be used for alignment, for example, a beard or a
    Guide nose or the like and the socket 3 a corresponding one
    Have groove or vice versa.
    The socket 2 also has a slot 7 running in the direction of the longitudinal axis 4 and a tensioning device 8. With the help of the tensioning device 8, the slot 7 is narrowed from its initial position shown in FIG. 2, in which it is unaffected by the tensioning device 8 Movable position in which the barrel root 3 is firmly anchored in the socket 2 and thus on or in the housing 1. The socket is designed such that it already receives the barrel root 3 with a press fit in the initial position of the slot 7, which is not influenced by the clamping device 8.
    In the example of FIGS. 1 and 2, the clamping device 8 is formed by two legs 9, 10, which are formed on both sides of the slot 7 on the socket 2, and one or more clamping screws (here: a clamping screw) 11. The clamping screw 11 is rotatably mounted with its screw head 12 on one leg 9 of the socket 2 and engages with its thread 13 in an internal thread 14 of the other leg 10 of the socket 2. The screw head 12 is mounted in a counterbore 15 of said one leg 9; the screw head 12 could alternatively e.g. just on the outside 16 of one
    Leg 9 or be supported in another way axially towards the other leg 10. In the exemplary
    7.13
    2 is the slot 7 by simple
    Tightening the clamping screw 11 from its initial position to its narrowed position.
    To be able to insert the barrel root 3 in the axial direction into the socket 2, although the socket 2 for receiving the
    Root 3 is formed with a press fit, the socket 2 also has a spreading device 17. With the spreading device 17, the slot 7 can be moved from its initial position into an expanded position in which the socket 2 is spread.
    In the example of FIGS. 1 and 2, the spreading device 17 is formed by the legs 9, 10, the tensioning screw 11 and an axial bearing 18, which axially fixes the tensioning screw 11 in said one leg 9 in its two axial directions. In this way, the slot 7 is closed by loosening the clamping screw 11, i.e. (at least partially) unscrewing the
    Clamping screw 11 from said other leg 10, from its starting position to its expanded position.
    In the example shown, the thrust bearing is through the
    Countersunk bore 15, a circumferential groove 19 formed in the countersunk bore 15 and a ring (here: a locking ring) 20 formed in the circumferential groove 19. This is the
    Screw head 12 axially fixed in its one axial direction in the counterbore 15 and in its other axial direction by the locking ring 20. The thrust bearing 18 could be on
    8/13 other way, e.g. in the one axial direction of the tensioning screw 11 by a pivot lever or slide bolt on the countersunk hole 15 partially covering the
    Outside 16 of one leg 9 or by a locking ring, which in the interior of the slot 7 in a groove
    Tensioning screw 11 is received, and in the other axial direction of the tensioning screw 11 continues through the leg 9 or the counterbore 15.
    It goes without saying that instead of the circlip 20 shown in the example in FIGS. 1 and 2, a snap ring or a
    Spiral circlip or the like. can be used.
    The socket 2 is in the example shown in one piece with the housing 1, i.e. formed as part of the housing 1. Alternatively, the socket 2 could also be separate from the housing 1 and anchored on or in the housing 1.
    Furthermore, the clamping device 8 and the spreading device 17 can be made in a different way than by the legs 9, 10
    Clamping screw 11 and the axial bearing 18 may be formed. The tensioning device 8 could e.g. a lever or cam mechanism, a link guide or a clamp spanning the socket 2. The spreading device 17 could also be a lever or cam mechanism or a link guide and thereby be designed and operated independently of the tensioning device 8 or have at least one common actuating element with the tensioning device 8, e.g. a scenery guide, a lever or
    Cam mechanism or the mentioned common clamping screw 11. Das
    The 9/13 common actuation element optionally has two actuation directions, in which one of the slots 7 is displaced from its initial position into its narrowed position and in the other, the slot 7 is displaced from its initial position into its expanded position.
    The invention is not limited to the illustrated embodiments, but encompasses all variants, combinations and modifications that are within the scope of the connected
    Claims fall.
