Description

The invention relates to a mounting device for a telescopic sight of a firearm according to the preamble of claim 1.

Telescopic sights for mounting on firearms are known and are particularly widespread for use on rifles. With a telescopic sight, a target that is further away can also be precisely detected. Mounting devices are known for mounting telescopic sights, which have fixed retaining pins and movable retaining pins, which are introduced into correspondingly shaped recesses in the firearm and thereby clamp a mounting bridge with a telescopic sight attached thereto. Pivoting levers are usually provided for the movement of the movable retaining pins, which protrude vertically upwards when the mounting bridge is placed on the firearm and are located directly next to the telescopic sight. The mounting bridge can be clamped by pivoting the pivoting lever. Handling is cumbersome due to the close proximity to a mount for the telescopic sight. In addition, the swivel levers can collide with the telescopic sight. It is also common to pivot the pivoting levers in different directions, which also makes handling more difficult. Such a mounting device is, for example DE 42 29 089 C2 to be taken, which also forms the basis for the two-part form of present claim 1.

Other conventional scope mounts are in FR 2 778 237 A1 , DE 203 13 331 U1 , DE 10 2010 011389 A1 , DE 10 2006 055 997 A1 , DE 298 05 865 U1 , DE 79 02 049 U1 , DE 10 2009 011 905 A1 , DE 103 58 666 A1 , DE 20 2009 003210 U1 , U.S. 4,310,980A and U.S. 3,750,318 A disclosed. A disadvantage of the solutions described there, however, is the complicated coupling of the pivoting lever to the retaining pin, which can easily lead to tilting.

It is the object of the present invention to create an alternative mounting device for a telescopic sight that is mechanically reliable, simple and easy to handle and in which a collision between the pivoting levers and the telescopic sight is also avoided.

This object is solved by an assembly device having the features of independent claim 1 . Advantageous configurations are the subject matter of dependent claims 2 to 11.

A mounting device for a telescopic sight of a firearm is proposed, having a mounting base with a first longitudinal side, a second longitudinal side, a longitudinal axis enclosed between the first longitudinal side and the second longitudinal side and a receptacle for holding the telescopic sight, a front and a rear insertion pin, at least a movable clamping pin, and in each case an actuating device for the at least one movable clamping pin, wherein the insertion pins are arranged laterally on the first longitudinal side of the mounting base along the longitudinal axis for engaging in first recesses of a barrel of the firearm, the at least one movable clamping pin for selectively engaging in a corresponding second recess of the barrel is arranged on the second longitudinal side and is movable transversely to the longitudinal axis. The invention provides that the respective actuating device has an elongate adjustment element coupled to an actuating element, which extends through an opening arranged in the mounting base, has a first end arranged on the first longitudinal side and a second end arranged on the second longitudinal side, the second end is firmly connected to the at least one clamping pin, and wherein the actuating device is designed to pull the associated clamping pin in the direction of the first longitudinal side by a rotation exerted via the actuating element. Because the at least one clamping pin is firmly connected to the second end of the elongate adjustment member, any canting between a working surface of the adjustment member and the counter surface of the clamping pin when tightening the actuating element to clamp the mounting device can be ruled out. The at least one clamping pin is preferably formed on the second end of the elongate adjusting member or is produced in one piece with it.

The mounting base is to be regarded as a type of base body of the mounting device, which can provide or accommodate the elements mentioned above. The first longitudinal side and the second longitudinal side enclose the longitudinal axis of the mounting base, which runs parallel to the barrel when the mounting device is mounted on the firearm. A telescopic sight can be fastened in the receptacle of the mounting device using suitable fastening means. For example, the mounting base could have fastening means that correspond to this.

The insertion pins are preferably arranged on an underside of the mounting base facing away from the receptacle. They allow the mounting device to be inserted into corresponding first recesses in the barrel of the firearm. The distances and Dimensions of the first recesses can correspond to a standard or recommendation, so that the sizes of the insertion pins and their distances from one another result from this. The insertion pins are preferably designed or arranged rigidly and immovably on the mounting base. When placing the assembly device on the barrel, it is sufficient to roughly position the insertion pins. By small, corrective displacement movements on the assembly device, the insertion pins come into alignment with the first recesses and are guided into them. It may be advisable to provide the plug-in pins in an area of an outer end with a slight taper or the first recesses in the area of an opening contour with a slight widening. The insertion pins will then be guided more easily into the first recesses.

The at least one movable clamping pin on the second longitudinal side is intended to engage selectively in a second recess. Due to the first and second recesses arranged on opposite longitudinal sides, the mounting device can be clamped firmly when the insertion pin is inserted by the engagement of the at least one clamping pin. The at least one clamping pin can be moved by the actuating device. The clamping pin in question can be moved transversely to the longitudinal axis of the mounting base and consequently completes a movement, at least the majority of which runs perpendicular to the longitudinal axis.

According to the invention, an actuator is provided which includes an elongate adjustment member which extends through the aperture located in the mounting base. The opening can be designed as a bore, which extends through the mounting base transversely to the longitudinal axis and is open on both longitudinal sides. The actuating device is designed to move the adjusting member along its longitudinal axis when it is rotated. The adjusting member then exerts a tensile force on the clamping pin, which is firmly connected to the adjusting member and is preferably even formed in one piece with it. The axial movement of the adjusting member can take place through a mechanical interaction with means arranged in or on the opening, which are explained further below. Cam surfaces are provided to allow axial movement of the adjustment member by rotation initiated with the actuator.

A particular advantage of this configuration is that the actuating device provides a defined adjustment path of the adjustment member, with which the adjustment path of the relevant clamping pin correlates directly. The clamping effect of the clamping pin does not depend on the screwing depth of a bolt coupled to the clamping pin in a nut and therefore does not have to be adjusted in a complex manner. In addition, it is possible to assign the actuating element a precise, predefined starting and end position that enables clamping and loosening with a high level of repeat accuracy. Furthermore, the mobility of the adjusting member and the independent clamping of a nut make it possible to arrange the actuating element on any side of the assembly device. Accordingly, the actuating element could be arranged both on the right-hand side in the firing or running direction and on the left-hand side in the firing direction. As explained below, the right-hand side in particular can be an option. In combination with the precisely specified start and end position, particularly ergonomic handling is made possible. This is expressed, for example, in blind operability of the actuating element with high precision and little adjustment effort at the same time.

In an advantageous embodiment, the actuating element is arranged at the first end. As a result, the actuating element can be located on a different side than the associated clamping pin. This promotes a more ergonomic arrangement of the actuating element in question, which is independent of the position of the clamping pin on an underside. The actuating element in question could therefore be located above an insertion pin, for example. This allows a thumb or other finger to be supported on the telescopic sight when actuating the actuating element and at the same time the actuating element to be manipulated with the other fingers of the same hand.

It is preferred that the actuating device is designed to move the at least one clamping pin into a clamping position or a released position by rotating the actuating element through 90°. The actuating element can thus be designed, for example, in the form of an actuating lever whose movement can be guided blindly. As stated above, the adjustment path of the actuating element can be precisely predefined without requiring any special adjustment. The adjustment path can consequently be adapted to the design of the mount, so that a collision with the telescopic sight is avoided. In particular, it is possible to define the adjustment path of the actuating element in such a way that the actuating element is not in any position protrudes along the adjustment path over the recording. As further explained below, it can be advisable that the actuating element is in an initial position transverse to the longitudinal axis. The actuating element is then preferably completely turned away from the receptacle. In the other position, the actuating element could then be arranged essentially parallel to the longitudinal axis.

According to the invention, the actuating device has a base body with a first cam surface, which is directed towards the adjustment member and which at least partially touches a second cam surface formed on the mounting base, the first cam surface and the second cam surface being designed to rotate toward one another about an axis formed by the adjustment member slide and linearly move the base body and thus the adjusting member along its axis during rotating sliding. The body could be mechanically connected to the elongate adjustment member. Should the actuating element be arranged at the first end, this could be implemented on the base body by means of a lever, a lug, a wing or the like in order to introduce a torque into the base body. By using the cam surfaces mentioned, the actuating device is mechanically very simple. When the actuating element rotates, the cam surfaces rotate relative to one another with surface contact. By specifically forming a surface profile of the two curved surfaces, the base body changes its distance from the mounting base and can thereby pull the adjusting member in the direction of the first longitudinal side and thus lead the associated clamping pin into a clamping position. Conversely, a released position can be achieved by moving in the opposite direction. The curved surfaces can also be designed in such a way that the clamping pin is only clamped in the last section of an adjustment path. This can improve the repeatability as well as the haptic perception of a successful clamping.

The assembly device could also have a spring element which is coupled to the base body or the adjustment member and is designed to urge the base body in the direction of the second cam surface. The spring element forces the base body in the direction of the second curved surface, so that the clamping pin is always in the position specified by the actuating device. The spring element could be designed in the form of a tension spring that always pulls the base body to the curved surface. Alternatively, a compression spring, such as a helical spring, could also be used, which exerts a force that presses the clamping pin into an open position and thus pulls the base body onto the second cam surface.

Preferably, the operating element has a lever for moving the operating element, the lever extending outwards transversely from its axis of rotation. The user can easily and intuitively operate such an actuating element with one or more fingers of one hand. Due to the limitation of the adjustment path, the lever can always be aligned in such a way that it does not protrude beyond the receptacle.

More preferably, the actuating device is designed such that the lever runs essentially parallel to the longitudinal axis of the mounting base in the one clamping position of the associated clamping pin. This then preferably extends backwards, i.e. facing a user.

The actuating device could be designed such that the lever runs substantially perpendicularly to the longitudinal axis of the mounting base when the associated clamping pin is released. The lever then extends in a direction offset by 90° and does not collide with the scope. Pulling the lever is intuitive and convenient.

The lever could also be turned away from the receptacle when the associated clamping pin is released. Consequently, the lever is down in this position. When moving the lever, it is not possible for it to scrape a side surface of the scope.

It is preferred that the lever can be moved counter to a running direction of the firearm by pivoting in order to clamp the clamping pin. The user can act with one hand on the lever, which is aligned parallel to the running direction, and rotate it from a downward position to a horizontal position by pulling the end of the lever around the axis of rotation of the base body. As explained above, the user can support himself on the telescopic sight with his thumb, for example, and rotate the lever with his index finger, for example.

Additionally, the submount or actuator could have a first stop surface and a second stop surface for limiting movement of the actuator. This can improve the haptic feedback, because hitting the base body leads to a clear limitation of the movement and a noticeably spontaneous mechanical resistance. This further improves the ease of operation and the mounting device can be clamped blindly.

It is preferred that the first longitudinal side is on the right in a running direction of the firearm. Ergonomic handling can be carried out in particular when the actuating element is arranged at the first end of the adjusting element.

The invention also relates to a firearm according to claim 12, having a barrel with first recesses arranged on the circumference, at least one second recess arranged on the circumference and a mounting device according to the preceding description.

Figures 1a and 1b show an exemplary embodiment of a mounting device 2 for a telescopic sight of a firearm in a three-dimensional representation. Here is an example in the plane of the drawing, a front side of the mounting device 2 is visible and a back side is covered. The assembly device 2 has an assembly base 4 with a first longitudinal side 6 , a second longitudinal side 8 and a longitudinal axis 26 enclosed between the first longitudinal side 6 and the second longitudinal side 8 . The first long side 6 is on the right, for example when the mounting device 2 is mounted, as viewed by a user of the relevant firearm when using it. The second long side 8 is therefore in use, seen from the user's left. A mount 10 for holding a telescopic sight is formed on an upper side of the mounting base 4 . This can have a bottom surface 9 which is enclosed by two elongate webs 11 . A telescopic sight can be placed and attached to this.

Two insertion pins 12 and 14 are located on the first longitudinal side 6 facing away from the receptacle 10 and are each arranged on an inner side of a projection of the mounting base 4 . By way of example, they are oriented obliquely inwards and facing away from the receptacle 10 . The insertion pins 12 and 14 are intended to be inserted into first recesses in a barrel of a firearm. The insertion pins 12 and 14 are, for example, at least partially flat and cylindrical in shape and have a diameter that exceeds their axial extent.

The insertion pins 12 and 14 are spaced apart by a distance determined by the first recesses in the barrel. These can be subject to a specific standard, for example. This results in approximately one size of the assembly device 2 along the longitudinal axis 26. The insertion pin 14 is a front insertion pin, with the insertion pin 12 being a rear insertion pin and lying behind the front insertion pin 14 in the weft direction. When the mounting device 2 is placed on the firearm, the rear insertion pin 12 faces a user who is using the firearm.

In order to clamp the mounting device 2 to the barrel, two clamping pins 16 are provided, for example, which are arranged on the second longitudinal side 8 . For example, the clamping pins 16 each have an insertion pin 12 or 14 opposite. The clamping pins 16 can be moved axially along an axis 28 . The axis 28 runs transversely to the longitudinal axis 26 and through an actuating device 18. This is intended to move the clamping pins 16 along the axis 28 and thereby selectively clamp the mounting device 2 to or from the barrel of the firearm.

The actuating device 18 has an actuating element 20 which is designed here in the form of a lever on a base body 24 . The base body 24 is connected to an elongate adjusting member 22 which extends to the clamping pins 16 . The actuating device 18 is designed in such a way that the lever 20 is shown in Fig. 1a runs parallel to the longitudinal axis 26 and the clamping pins 16 are in a clamping position. In the exemplary embodiment shown, the two clamping pins 16 are each formed on the second end of the adjustment member 22, ie formed in one piece with it. However, they can also be manufactured as individual parts, which are then connected to the second end of the adjusting member 22 in a non-positive manner. As a result, tilting between the clamping pin 16 and the adjusting member 22 can be reliably avoided when the actuating element 20 is tightened.

In Fig. 1b the levers 20 are pivoted into a position running perpendicularly to the longitudinal axis 26 and protrude downwards. In doing so, they face away from the receptacle 10 . In this position, the clamping pins 16 are released and the mounting device 2 can be put on or off. During the movement of the actuating element 20 from the in Fig. 1b position shown in the in Fig. 1a Position shown, the actuator 20 can not scrape the telescopic sight.

In Figure 2a the adjusting member 22 is designed, for example, similar to a shank of a threaded bolt which is firmly connected to the clamping pin 16 or formed on it. In the example shown, the clamping pin 16 is designed as a flat, round disk with a chamfer pointing axially outwards. The rotational position of the clamping pin 16 is irrelevant if the clamping pin is circular. On a side facing away from the clamping pin 16 , the adjusting member 22 has a thread 23 which is screwed into a corresponding threaded bore 25 in the base body 24 . A counter element 36 in the form of a grub screw or a similar element is provided adjacent thereto. This can be pressed axially onto the adjustment member 22 from an outside by screwing it in, so that the adjustment member 22 is connected to the base body 24 in a torque-proof and tensile manner.

A first cam surface 40 is arranged on a side of the base body 24 that faces the mounting base 4 and is connected to a second cam surface 38 (see FIG Figure 5b ) is designed to be complementary. By turning the base body 24, the two cam surfaces 38, 40 slide on one another and thus lead to an axial movement of the adjusting member 22 and thus of the clamping pin 16 along the axis 28 of the adjusting member 22. This allows the clamping pin 16 to be selectively moved into or out of a second recess 34 of a barrel 30 of a firearm. The second recesses 34 can be crescent-shaped or crescent-shaped.

On an opposite side, however, the above-mentioned first recesses 32 are provided, which are intended to receive the insertion pins 12 and 14 . Accordingly, the mounting device 2 can clamp itself between the first recesses 32 and the second recesses 34 .

In Figure 2b this is shown again without run 30. A recess or indentation 42 can be seen in both illustrations, which is directed from the mounting base 4 to the clamping pin 16 . This could accommodate a compression spring, for example a helical spring, which urges the clamping pin 16 into a position facing away from the mounting base 4 . As a result, the base body 24 is simultaneously pulled in the direction of the mounting base 4 and surface contact between the cam surfaces 38 and 40 is caused.

In the Figures 2c and 2d the clamping pin 16 is shown in a released position, in which the actuating element 20 runs transversely to the longitudinal axis 26 and faces away from the receptacle 10 . In this state, as in Figure 2c clearly visible, the mounting device 2 can be placed on the barrel 30 or removed from it.

3 shows a 5-side view of the mounting device 2 with the clamping pin 16 in the clamping position. It is particularly clear here that the actuating elements 20 nestle flat against the mounting base 4 from below in the clamped position. The mounting base 4 could be used, for example, to limit the displacement of the actuating element 20 in this direction.

4 shows a 5-side view of the mounting device 2 with the clamping pin 16 loosened. It is clear that the actuating elements 20 are always clearly turned away from the receptacle 10 throughout their adjustment path, which preferably comprises 90°. Scraping or colliding with a telescopic sight placed on it is avoided.

The Figures 5a and 5b show the mounting base 4 without the actuating device 18. The cylindrical shape of the insertion pins 12 and 14 can be seen here. The second curve surfaces 38 have a certain profiling, which serves to move the base body 24 along the axis 28 . On the peripheral side, the second curved surfaces 28 are formed with different heights along a longitudinal axis of the opening 44 .

Finally shows 6 a sectional view of the mounting base 4 in the area of the insertion pin 14. As indicated, the second cam surface 38 can have a cam surface bottom 46 and a cam surface plateau 48 on part of its peripheral surface.

The invention is not limited to one of the embodiments described above, but can be modified in many ways.

In summary, the present invention relates to a mounting device 2 for a telescopic sight of a firearm, which has a mounting base 4 with a first longitudinal side 6, a second longitudinal side 8 and a receptacle 10 for holding the telescopic sight, a front and a rear insertion pin 12, 14, at least one movable Clamping pin 16, and an actuating device 18 for the clamping pin 16 has. The insertion pins 12, 14 are arranged on the first longitudinal side 6 for engaging in first recesses 32 of a barrel 30 of the firearm, with the clamping pin 16 being arranged on the second longitudinal side 8 for selectively engaging in a corresponding second recess 34 and being movable transversely to the longitudinal axis 26 is. The actuating device 18 has an elongate adjustment member 22 coupled to an actuating element 20, which extends through an opening 44 arranged in the mounting base 2, a first end arranged on the first longitudinal side 6 and a second end arranged on the second longitudinal side 8, with the second end is firmly connected to the clamping pin 16 and preferably formed thereon. The actuating device 18 is designed to rotate the clamping pin 16 in the direction of the first longitudinal side 6, thereby enabling the mounting device to be reliably clamped in the recesses 32, 34 of the barrel 30 of the firearm without damaging a working surface of the adjustment member 22 can tilt with a counter surface of the clamping pin 16

All of the features and advantages resulting from the claims, the description and the drawing, including structural details, spatial arrangements and method steps, can be essential to the invention both on their own and in a wide variety of combinations.
