Description:
FIELD OF THE INVENTION 
       [0001]    The invention relates to a mounting device for the detachable attachment of an aiming device to a handgun. The invention further relates to a housing of a handgun, which comprises an attachment device for such a mount. 
       BACKGROUND 
       [0002]    Such a mounting device is known from U.S. Pat. No. 3,579,840 A. Therein, in each case a fixed clamping jaw as well as an adjustable clamping jaw on the opposite side are arranged on a ring-shaped holding device. On the bottom side of the ring-shaped holding device, between the two clamping jaws, a bar-shaped repelling roller is provided for the engagement in a corresponding continuous transverse groove on a base portion which can be attached to the handgun. By means of the repelling roller, the forces acting at the time of the firing are absorbed, and as a result an improved precision can be achieved. However, as a result of the continuous transverse grooves, the attachment device is also weakened, and thus the stiffness is affected. 
       SUMMARY OF THE INVENTION 
       [0003]    The invention relates to a mounting device and a housing of a handgun for such a mounting device, which enable a stable and accurately reproducible attachment of an aiming device. 
         [0004]    In the mounting device according to the invention, the repelling roller comprises two mutually facing and mutually separate engagement elements for the engagement in two mutually separate recesses on the handgun. The housing, which is part of the mounting device, contains an attachment device which comprises two mutually facing recesses that are separated from each other by a middle bar, for the engagement of the engagement elements on the repelling roller. By means of the middle bar, an additional stability on the housing is achieved, which allows an improved precision, and a high repetition accuracy during the mounting of an aiming device. The repelling forces acting at the time of the firing can be absorbed better, and an extremely precise positive locking connection is nevertheless achieved, between the mounting device and the housing or system casing, or the other portions of the handgun, making possible a high and consistent aiming precision, even after repeated removal and renewed mounting of the aiming device. 
         [0005]    It is preferable to form a slot for receiving a middle bar extending in the longitudinal direction on the handgun, between the two engagement elements of the repelling roller. As a result, an accurate and precise connection and additional lateral guidance between the mounting device and the handgun are achieved. 
         [0006]    In a further advantageous embodiment, the returning roller comprises a base body which is arranged in a bore of the holding device, and on which the engagement elements can be formed. By means of the, for example, circular, base body, the repelling roller can be arranged in a bore on the bottom side of the holding device. 
         [0007]    In a further advantageous embodiment, the engagement elements opposite the mutually facing clamping jaws, and also the recesses for the engagement elements opposite the recesses for the clamping jaws are offset toward the front or the rear in the longitudinal direction of the holding device or of the attachment device. As a result, the clamping area of the clamping jaws is not limited. 
         [0008]    In a particularly stable embodiment which is easy to mount, the holding device is configured in the shape of a mounting bridge having front and rear clamping jaws. However, the holding device can also be formed as a single mounting. It is also possible to attach an aiming telescope or another aiming device to a handgun by means of two, for example, ring-shaped, individual mountings. 
         [0009]    The attachment device is preferably integrated in the housing, and it can contain two mounting bases that are separated from each other in the longitudinal direction of the housing, on which in each case two facing recesses are provided for the clamping jaws and in each case two groove-shaped recesses for the repelling roller, which extend transversely to the longitudinal direction of the housing and which are separated by a middle bar from each other in each case.

     DETAILED DESCRIPTION 
       [0015]    In  FIG. 1 , a housing  1  of a repeater rifle is shown, which housing is configured as a system casing or a breech casing. The housing  1  comprises on its front end a sleeve-shaped barrel holder  2  for the detachable attachment of a barrel. Furthermore, on the housing  1 , a recess  3  for receiving a breech of the repeater rifle is provided. On the housing  1 , next to the barrel, in a manner which in itself is known, a fore end of the barrel, which is not shown, and a rear end of the barrel, which is also not represented, of the repeater rifle are attached. For the detachable attachment of an aiming telescope or of another aiming device, the housing  1  comprises additionally on its upper side an attachment device for a mounting device  4  shown in  FIG. 2 . 
         [0016]    In the embodiment example shown in  FIG. 1 , the attachment device comprises facing side recesses  6  for the engagement of the clamping jaws  17  and  19  shown in  FIG. 4 , as well as mutually separate recesses  9  formed as transverse grooves for the engagement of a repelling roller  10  represented in  FIG. 2 . The housing  1  comprises on its upper side two mounting bases  11  and  12  which are mutually separate in the longitudinal direction of the housing  1 , and on which in each case two facing recesses  6  are provided as well as two groove-shaped recesses  9  which extend transversely to the longitudinal axis of the housing  1  and which are separated from each other by a middle bar  13 . The middle bar  13  here extends in the longitudinal direction of the housing  1 . The recesses  6  are designed as side milled slots in the form of a circular arc. The recesses  9 , which are configured as transverse grooves, are offset toward the front or the rear opposite the recesses  6  in the longitudinal direction of the housing  1 . The recesses  9  can be produced in a simple manner, for example, using an end mill. 
         [0017]    The mounting device  4  shown in  FIGS. 2-4  in different views comprises a holding device  14  configured as a mounting bridge and having front and rear mounting portions  15  and  16  for setting on the mounting bases  11  or  12  of the housing  1 . On the front and rear mounting portions  15  and  16  of the bridge-shaped holding device  14 , a stationary clamping jaw  17  and a facing recess  18  for an adjustable clamping jaw  19  shown in  FIG. 4  are provided in each case. The two recesses  18  comprise beveled outer faces  20  for the application of the adjustable clamping jaws  19  and the bores  21 , as well as the grooves  22  for an attachment lever  23  shown in  FIG. 4 , or other elements for the actuation of the adjustable clamping jaws  19 . Both the fixed clamping jaws  17  and also the adjustable clamping jaws  19  comprise, on the free ends thereof, semicircular clamping jaws  24 , which are beveled on both sides, for engagement in the recesses  6 , which are in the shape of a circular arc, on the housing—[sic] 1. 
         [0018]    On the bottom side of the front and rear mounting portions  15  and  16 , two beveled application faces  25 , which are shown in  FIG. 2 , are provided for the application of the holding device  14  on the roof-shaped application faces  26  of the mounting bases  11  and  12 , faces which can be seen in  FIG. 1 . In the bridge-shaped holding device  14 , bores  27  are arranged for the attachment of ring holders or other holders for the attachment of the aiming telescope or of other aiming devices. Moreover, on the bottom side of the two mounting portions  15  and  16  of the holding device  14 , a repelling roller  10  with two mutually separate bar-shaped engagement elements  28  is provided in each case, for the positive-locking engagement in the two mutually separate groove-shaped recesses  9  on the housing  1 . 
         [0019]    As is apparent in particular from  FIG. 3 , the repelling roller  10  comprises a round base body  29  which is inserted in a corresponding bore  30  on the bottom side of the bridge-shaped holding device  14 . Between the two bar-shaped engagement elements  28 , a slot  31  for receiving the middle bar  13 , which is configured on the housing  1  of the handgun and which extends in the longitudinal direction of the housing  1 , is provided. Due to the orientation of the middle bar  13  in the longitudinal direction of the housing  1 , an accurate and precise connection and an additional lateral guidance between the mounting device  4  and the housing  1  occur, since the bar-shaped engagement elements  28  are led by the middle bar  13  extending in the longitudinal direction of the housing  1  for the positive locking engagement in the groove-shaped recesses  9 . 
         [0020]    The positive-locking engagement of the bar-shaped engagement elements  28  of the repelling roller  10  occurs in such a manner that the bar-shaped engagement elements  28  like a bridge overlap the middle bar  13  extending in the longitudinal direction of the housing  1 . An additional inner bore  26  for the attachment of, for example, ring-shaped, holders or other holding devices, can be covered by the round base body  29 . The bar-shaped engagement elements  28  are rounded off on their mutually facing sides, so that they fit with the best possible positive-locking connection in the groove-shaped recesses  9  produced, for example, by an end mill.
