EP2743631A2 - Rifle telescope mounting with adjustable predefined inclination - Google Patents

Abstract

The assembly (1) has a base body (2) and a cap (3) that exhibit a positive connection by arrangement of clamping screws at an angle of less than 90 degree. The base body and the cap comprise a conical joint, and a projection comprises a circular pin, where an adjusting wheel is rotatably supported on the pin. The base body and the cap are supported under tensile stress by a tension spring. A peripheral part of the adjusting wheel is provided with multiple planar faces. An outer surface of the adjusting wheel comprises a spiral shaped flank lead.

Description

The invention relates to a scope mount with adjustable pre-tilt to change the pre-tilt angle between scope and barrel when shooting at long distances so that the vertical displacement of the scope is sufficient to adjust it to the desired shooting distance can.

After firing from a firearm, the projectile follows a trajectory, the curvature of which depends on various influencing factors, such as projectile weight and projectile velocity. After shooting the weapon at, for example, 100 m, the telescopic sight can be adjusted to different shooting distances by adjusting the reticle. However, the adjustment path of each riflescope is mechanically limited, so that, for example, only a distance range of about 50 - 600 m can be covered. If the desired shooting distance is outside this range, for example at 800 m, this can no longer be achieved by adjusting the reticle.

Riflescopes are connected to the firearm using riflescope mountings. Normally, the optical axis of the telescopic sight and the barrel axis of the weapon are coaxial with each other. Due to the greatly decreasing at long distances to the target trajectory of the projectile in such cases, the riflescope is mounted with a vorgeneigten scope mount on the weapon. In this case, different pretilt angles are necessary for different combinations of ammunition, barrel, weapon system, scope mount, telescopic sight and desired shot distance, so that the available vertical displacement of the scope is sufficient to set the reticle to different firing ranges.

If the riflescope is mounted with a riflescope assembly which has a fixed pretilt of, for example, 20 MOA ( M inute O f A ngle, angular minutes), this combination may suit a particular application. However, another combination may require a different pretilt angle be able to set the sight of the riflescope to the desired shooting distance can.

This problem can be addressed by having multiple riflescope mountings with different fixed integrated ripples available. However, this requires a corresponding variety of parts and warehousing. In addition, by trial and error, so by multiple remounting, the scope mount with the appropriate pre-tilt would have to be found. A much simpler and more practical solution to this problem is a scope mount where the tilt is adjustable.

A rifle scope mount with adjustable forward tilt can be used in hunting or sport shooting. However, especially on military-used weapons with a particularly long range and correspondingly powerful calibers, such an assembly brings decisive advantages for the user.

An obvious construction of such a scope mount consists of a hinged section and a section with an adjustment mechanism. Known hinges, as in the in the US 8079172 B2 , of the US 8240075 B1 , of the US 7543405 B1 , of the US 7140143 B1 , of the US 6662486 B2 , of the US 5400539 , of the US 5086566 , of the US 4317304 , of the DE 20 2010 003 668 U1 , of the US 2004/0144013 A1 and the US 3340614 described, have two components which form the hinge in conjunction with a cylindrical shaft or a screw. In order to ensure the function of the hinge, the shaft or the screw in at least one of the two parts must have a slight radial play. Although this game is very small in precisely worked hinge joints, but can lead to precision losses during use, when the forces are large enough and the shaft is radially displaced within the bore in the context of this game. Also, the axial clamping together of the hinge by means of a screw is due to the necessary play the shaft in one of the components ultimately a frictional and no positive connection.

Absolute reliability and ruggedness in the harshest of conditions is crucial, especially for military-grade weapons. To achieve this, the scope mount from as few as possible Parts exist and the connection of the individual components should be positive and not frictionally. In addition, as little as possible parts to be lost should be installed, which means that the scope mount for adjusting the tilt should not be disassembled or removed from the weapon if possible. Of particular importance is the simplest possible handling of the adjustment so that operator error can be largely excluded.

The object of the invention is to overcome the described disadvantage of the prior art.

The object of the invention is achieved by a riflescope mounting with adjustable tilt, which is characterized in that a base body and an attachment by the arrangement of a clamping screw at an angle greater than the self-locking material pairing and less than 90 ° have a positive connection.

The object of the invention is further achieved by telescopic sight mounting with adjustable pre-tilt, which is characterized in that the base body and the attachment have a conical connection.

The scope mount according to the invention meets the requirements mentioned in an excellent manner.

A particularly advantageous embodiment is explained below with reference to the figures.

Fig. 1 and 2 show a riflescope mounting 1, the main body 2 by way of example with a in the utility model DE 20 2009 017 398.4 explained clamping system is provided, wherein the base body is fixed by means of the clamping system on a Picatinny rail 4. The Picatinny rail is in turn mounted on the gun case (not shown in the figures). As a connection to the weapon, other types of attachment are possible, for example, in hunting weapons very common swivel mounting or various types of Aufkippmontagen and fixed installations. The attachment 3 clamps together with the front half-shell 5 and the rear half-shell 6, the riflescope 7. Other types of connection between the target device and essay 3. Also possible, the top of the article 3 may be provided with a further Picatinny rail, on which the target device is mounted.

The main body 2 has a taper 8 with a bore 9 (see Fig. 3 ). The attachment 3 has a countersink 10 (see Fig. 4 ) and an internal thread 11 (see Fig. 3 ) on.

In the installed state (see Fig. 5 The first clamping screw 12 thus connects the main body 2 backlash with the attachment 3. The main body 2 forms with the attachment 3 a hinge about the hinge axis 13. In contrast to a compound with a cylindrical hinge pin guaranteed absolute freedom of play in a conical connection, which is a great advantage.

The main body 2 has an extension 14 and this in turn a circular pin 15 on which the thumbwheel 16 is rotatably mounted (see Fig. 6 ). As a captive for the setting wheel 16 of the threaded pin 17 which engages in the annular groove 18 of the circular pin 15 (see Fig. 7 ). The threaded pin 17 is secured with locking lacquer in the internal thread 19 against rotation (see Fig. 8 ).

The thumbwheel 16 has on its circumference, for example, eight flat surfaces with associated labels. To clarify the function, the surface 20 is picked out by way of example, to which the lettering "20" is assigned. Each surface is assigned a certain angle of the pre-tilt. The necessary distance "A" in Fig. 8 the surfaces to the axis of rotation of the adjusting wheel 16 can be calculated via angle functions. In the exemplary embodiment shown, there are eight possible angular positions from 0 to 70 MOA in ten MOA increments. Other numbers of areas with different pitches are possible. Likewise, the lateral surface of the adjusting wheel 16 may have a slope in the form of a spiral (not shown in the figures) to allow a continuous adjustment of the inclination angle. For tool-free handling the adjusting wheel 16 is provided with a corrugation 21.

Out Fig. 7 It can be seen that a slot 22 extends through the circular pin 15 and the extension 14. This slot 22 has an angle ß to the contact surface 23 on the attachment 3 (see Fig. 4 and 9 ).

The slot 22 is from a second clamping screw 24 (see Fig. 10 ), which rests in the clamped state with the base 25 of the head 26 on the surface 27 of the circular pin 15. The surface 27 is at right angles to the slot 22. The threaded shaft 28 of the second clamping screw 24 engages in the internal thread 29 in the attachment 3. The internal thread 29 has the same angle ß to the contact surface 23 as the slot 22 (see Fig. 4 . 7 and 9 ).

Due to manufacturing tolerances on the diameter of the taper 8 and the diameter of the countersink 10 results between the wall 30 on the extension 14 and the wall 31 on the top 3, a more or less large gap. This gap is compensated by shims 32. Depending on the size of the gap correspondingly many spacer plates 32 are inserted (see Fig. 7 ).

The extension 14 and the circular pin 15 have a first bore 33 and a second bore 34. In these bores sits a first clamping pin 35 and a second clamping pin 36. These two dowel pins pass through the holes 37 and 38 in the spacer plate 32 and serve for their positioning (see Fig. 3 and 7 ).

The cutouts 39 and 40 ensure freedom from collision with the clamping pins 35 and 36 (see Fig. 4 ).

A tension spring 41 extends through the vertical bore 50 in the attachment 3 and the vertical bore 51 in the base body 2 (see Fig. 11 ).

The first eyelet 42 of the tension spring 41 is penetrated by a third clamping pin 43, which sits in the bore 44 in the attachment 3.

The second eyelet 45 of the tension spring 41 is penetrated by a fourth clamping pin 46, which sits in the bore 47 in the base body 2.

The fifth clamping pin 52 in the bore 53 in the attachment 3 projects into the bore 54 in the extension 14 in the base body 2. The diameter of the bore 54 is slightly larger than the diameter of the clamping pin 52. This arrangement prevents the second clamping screw when loosening or tightening 24 too strong lateral pushing away of the essay 3 (see Fig. 12 ).

The manipulation of the pretilt adjustment is done in five steps:

1. Loosen the first clamping screw 12th

Here, one turn of the screw is sufficient.

2. Loosen the second clamping screw 24th

Depending on the pitch of the thread about two turns of the screw are sufficient. Since now both clamping screws are released, the compression spring 48 provides in the bore 49 (see Fig. 5 and 7 ) that the conical connection does not dissolve but still remains rotatable about the hinge axis 13.

3. Select the desired angle of inclination by manually turning the adjusting wheel 16.

In this case, the setting wheel 16 must be turned so far until the corresponding surface 20 rests against the contact surface 23. By the tension spring 41, the contact surface 23 is always against the surfaces on the circumference of the adjusting wheel 16th drawn. Since when turning from one surface to the next, the tension spring 41 is stretched and relaxed again, there is a tactile detent on each surface.

4. tighten the second clamping screw 24th

The angle β is chosen so that it is less than 90 ° and greater than the angle of self-locking of the material pairing of the wall 31 of the attachment 3 and the spacer plate 32.

The self-locking describes in mechanics the resistance caused by friction against the displacement of two adjoining bodies. In this case, the angle at the inclined plane is referred to as the angle of the self-locking, is present in the static friction. If the angle of self-locking is exceeded, sliding friction is present and the two bodies are thus no longer self-locking. The size of the angle of self-locking depends on the surface roughness of the material pairing.

The attachment 3 is thus pulled with its contact surface 23 against the surface 20 of the setting wheel 16 and at the same time with its wall 31 against the spacer plate 32 and this in turn against the wall 30 on the extension 14. Thus, there is a positive connection. Would the second clamping screw 24 transverse to the firing direction, ie at 90 ° angle to the surfaces 30 and 31, a merely frictional connection would be present, since in this case the attachment 3 is not pulled with its contact surface 23 against the surface 20 of the setting wheel 16 would. If the angle ß selected so that it is smaller than the angle of self-locking - thus within the self-locking - the material pairing of the wall 31 of the attachment 3 and the spacer plate 32, so would also be present only a frictional connection, as in this case the essay 3 is not pulled with its contact surface 23 against the surface 20 of the adjusting wheel 16.

5. tightening the first clamping screw 12th

Points 1 and 2 or points 4 and 5 when handling the adjustment can also be carried out in reverse order.

The scope mount can basically also be made in two parts (not shown in the figures). This means that the region of the hinge with the front half-shell 5 and the region of the adjusting wheel 16 with the rear half-shell 6 have no connection. Both areas then sit separately on the Picatinny rail 4 or are connected according to the mounting method with the weapon.

In other embodiments of the invention not shown in the figures, the extension 14 with the circular pin 15 and the setting wheel 16 are not seen in the weft direction rear end of the assembly, but at the front end. Accordingly, the conical connection is then at the rear end of the assembly.

The thumbwheel 16 and the taper 8 sit in the exemplary embodiment of the invention on the right in the firing direction right side of the scope mount. These elements can also be arranged on the left side.

In a further embodiment not shown in the figures, the taper 8 part of the attachment 3 and the countersink 10 in consequence of its part of the body 2 be.

In a further variant, the extension 14 with the circular pin 15 may be part of the attachment 3. The internal thread 29 for the second clamping screw 24 is in this embodiment in consequence of the main body. 2
