Rifle telescope mounting with adjustable predefined inclination

p0001The invention relates to a scope mount with adjustable forward tilt to change when shooting at long distances the pre-tilt angle between scope and running so can that of the vertical displacement of the sighting telescope is sufficient to adjust it to the desired shooting distance can.

p0002After firing of a gun the bullet of a trajectory whose curvature of various factors, such as bullet weight and muzzle velocity depends follows. After aligning the weapon, for example, 100 m can be adapted to different distances by adjusting the reticle riflescope. The displacement of each riflescope is however mechanically restricted so that, for example, only a distance range of approximately 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.

p0003Scopes are connected by means of scope mounts with the firearm. Normally, the lie to each other, the optical axis of the telescopic sight and line of the barrel of the gun coaxially. Due to the large distances in the target steeply sloping trajectory of the projectile, the sighting telescope is mounted with a forward-leaning scope mount on the gun in such cases. Here are needed at different combinations of unused ammunition, barrel, weapon system, scope mount, scope and desired shooting distance different pre-tilt angle, so that the available vertical adjustment of the scope for adjusting the reticle sufficient to different shooting distances.

p0004Is that scope with a scope mount that a fixed pretilt of for example 20 MOA (<u>M</u>inute <u>O</u>f <u>A</u>ngle, angle minutes) which is mounted, so this combination may be suitable for a particular application. In another combination, however, another pre-tilt angle may be necessary to adjust the reticle of the riflescope to the desired shooting distance can.

p0005This problem can be addressed by more scope mounts are different fix integrated pretilts available. However, this requires a corresponding number of parts and warehousing. Moreover, would have to be with the appropriate pretilt found through trial and error, ie by repeated remounting, the scope mount. A much simpler and more practical solution to this problem is a scope mount, in which the inclination is adjustable.

p0007A scope mount with adjustable forward tilt can be used in hunting or sport shooting. However, especially in military use weapons with very long range and correspondingly powerful calibres brings such an assembly decisive advantages for the user.

p0008One obvious design of such a scope mount consists of a hinge portion and a portion with an adjustment mechanism. Known hinges as in the<patcit id="pcit0016" dnum="US8079172B2"><text>US 8079172 B2</text></patcit>, of the <patcit id="pcit0017" dnum="US8240075B1"><text>US 8240075 B1</text></patcit>, of the <patcit id="pcit0018" dnum="US7543405B1"><text>US 7543405 B1</text></patcit>, of the <patcit id="pcit0019" dnum="US7140143B1"><text>US 7140143 B1</text></patcit>, of the <patcit id="pcit0020" dnum="US6662486B2"><text>US 6662486 B2</text></patcit>, of the <patcit id="pcit0021" dnum="US5400539A"><text>US 5400539</text></patcit>, of the <patcit id="pcit0022" dnum="US5086566A"><text>US 5086566</text></patcit>, of the <patcit id="pcit0023" dnum="US4317304A"><text>US 4317304</text></patcit>, of the <patcit id="pcit0024" dnum="DE202010003668U1"><text>DE 20 2010 003 668 U1</text></patcit>, of the <patcit id="pcit0025" dnum="US20040144013A1"><text>US 2004/0144013 A1</text></patcit> and the <patcit id="pcit0026" dnum="US3340614A"><text>US 3340614</text></patcit> described, comprise two components which form the hinge in connection with a cylindrical shaft or a screw. To ensure the function of the hinge, the shaft or the screw must have at least one of the two parts of a slight radial play. This game is in precisely machined hinge connections very small, but can during use result in precision loss when the forces are large enough and the shaft within the bore under this game is displaced radially. Also, the axial clamping together the hinge means of a screw, due to its necessary play of the shaft in one of the components ultimately a friction and no positive connection is.

p0009Absolute reliability and robustness in the harshest conditions, particularly in military use weapons crucial. to To achieve this, the scope mount consist of as few individual parts and the connection of the individual components to be fit and not friction. In addition to a minimum of loose parts to be installed, which means that the scope mount must not be disassembled to adjust the forward tilt, if possible, or removed from the weapon. Of particular importance is also the simplest possible handling of the adjustment so that operator error can be largely excluded.

p0010The object of the invention is to overcome the described drawback of the prior art.

p0011The object of the invention is achieved by a scope mount with adjustable forward tilt, which is characterized in that a base body and an essay by the arrangement of a clamping screw at an angle greater than 90 ° exhibit the self-locking of the material pairing and less a positive connection.

p0012The object of the invention is further achieved by scope mount with adjustable forward tilt, which is characterized in that the base body and the attachment have a conical connection.

p0013The scope mount invention meets the requirements set out in an excellent manner.

p0014A particularly advantageous embodiment is described in detail hereinafter with reference to FIGS.

p0016<figref idrefs="f0001">Fig. 1</figref> and <figref idrefs="f0002">2</figref> show a scope mount 1, the basic body 2 by way of example a in the utility model <patcit id="pcit0027" dnum="DE202009017398"><text>DE 20 2009 017 398.4</text></patcit> explained clamping system is provided, wherein the base body by means of the clamping system is mounted on a Picatinny rail. 4 The Picatinny rail is in turn mounted on the housing of the firearm (not shown in the figures). When connection to the weapon, other types of mounting are possible, for example, very common in Jagdwaffenbau pivot assembly or various types of Aufkippmontagen and fixed mounting. The top 3 clamped together with the front half-shell 5 and the rear half-shell 6 riflescope are 7 possible, other types of connection between the target device and attachment 3. The top of the tower 3 can for example be provided with a further Picatinny rail, on which is mounted the target device.

p0017The base body 2 has a taper 8 with a bore 9 (see <figref idrefs="f0003">Fig. 3</figref>). The top 3 has a conical recess 10 (see<figref idrefs="f0004">Fig. 4</figref>) And an internal thread 11 (see <figref idrefs="f0003">Fig. 3</figref>) on.

p0018In the assembled state (see <figref idrefs="f0005">Fig. 5</figref>) Is the taper 8 in the countersink 10. The first clamping screw 12 thus connects the body 2 without play with the top 3. The base body 2 forms with the top 3 a hinge about the hinge axis 13. In contrast to a connection with a cylindrical hinge pin ensures zero backlash at a cone connection, which is a great advantage.

p0019The base body 2 has an extension 14 and this in turn a circular spigot 15 on which the adjusting wheel 16 is rotatably mounted (see <figref idrefs="f0006">Fig. 6</figref>). As captive for the adjusting wheel 16 of the set screw 17, which serves in the annular groove 18 of the circular spigot 15 engages (see<figref idrefs="f0007">Fig. 7</figref>). The threaded pin 17 is locked with locking varnish in internal thread 19 against rotation (see<figref idrefs="f0008">Fig. 8</figref>).

p0020The adjusting wheel 16 has on its periphery, for example, eight plane surfaces with associated labels. To clarify the function is an example of the surface singled out 20, which is associated with the label "20". Each area is assigned a specific angle of forward inclination. The necessary distance "A" in<figref idrefs="f0008">Fig. 8</figref> the faces the axis of rotation of the adjusting wheel 16 can be calculated using trigonometric functions. In the embodiment example shown, eight possible angular positions of 0 to 70 result in ten MOA MOA increments. Other numbers of surfaces with different pitches are possible. Likewise, the lateral surface of the adjusting wheel 16 may be a slope in the form of a spiral having (not shown in the figures) to enable a stepless adjustment of the inclination angle. For toolless handling the setting wheel 16 is provided with a ribbing 21st

p0021Out <figref idrefs="f0007">Fig. 7</figref> it is evident that through the circular spigot 15 and the extension 14 a slot 22 runs. This slot 22 has an angle ß to the contact surface 23 on the attachment 3 (see<figref idrefs="f0004">Fig. 4</figref> and <figref idrefs="f0009">9</figref>).

p0022The slot 22 is of a second clamping screw 24 (see <figref idrefs="f0010">Fig. 10</figref>) Penetrated, which rests against the surface 27 of the loop pin 15 in the clamped condition with the base 25 of the head 26th The surface 27 is at right angles to the elongated hole 22. The threaded shank 28 of the second locking screw 24 engages in the internal thread 29 in the cap 3. The internal thread 29 has the same angle ß to the abutment surface 23 as the elongated hole 22 (see<figref idrefs="f0004">Fig. 4</figref>. <figref idrefs="f0007">7</figref> and <figref idrefs="f0009">9</figref>).

p0023By manufacturing tolerances on the diameter of the truncated pin 8 and the diameter of the countersink 10 is formed between the wall 30 on the extension 14 and the wall 31 at the top 3, a more or less large gap. This gap is compensated by shims 32nd Depending on the size of the gap, many spacer plates 32 are correspondingly inserted (see<figref idrefs="f0007">Fig. 7</figref>).

p0024The extension 14 and the circular spigot 15 have a first bore 33 and a second bore 34th In these holes, a first dowel pin sits 35 and a second spring pin 36. These two dowel pins extend through the holes 37 and 38 in the spacer plates 32 and serve to their positions (see<figref idrefs="f0003">Fig. 3</figref> and <figref idrefs="f0007">7</figref>).

p0025The cutouts 39 and 40 provide for collisions to the dowel pins 35 and 36 (see <figref idrefs="f0004">Fig. 4</figref>).

p0026A tension spring 41 extends through the vertical hole 50 in the top 3 and the vertical bore 51 in the main body 2 (see <figref idrefs="f0011">Fig. 11</figref>).

p0027The first loop 42 of tension spring 41 is penetrated by a third clamping pin 43, which is seated in the bore 44 in the article. 3

p0028The second loop 45 of tension spring 41 is penetrated by a fourth spring pin 46, which is seated in the bore 47 in the base body. 2

p0029The fifth clamping pin 52 in the bore 53 in the top 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 dowel pin 52. This arrangement prevents the loosening or tightening the second clamping screw 24 too strong a lateral pushing away of the cap 3 (see <figref idrefs="f0012">Fig. 12</figref>).

p0030The handling of the adjustment of the pre-tilt is done in five steps:

1. Loosen the first clamping screw 12th

p0031Here, one rotation of the screw is sufficient.

2. Disconnect the second clamping screw 24th

p0032Depending on the pitch of the thread is about two revolutions of the screw is sufficient. 48 Now that both clamping screws are loosened, makes the compression spring in the hole 49 (see<figref idrefs="f0005">Fig. 5</figref> and <figref idrefs="f0007">7</figref>) That the cone connection is not from each other but still solves rotatable about the hinge axis 13 remains.

3. By manually turning the adjusting wheel 16 to select the desired angle.

p0033Here, the setting wheel 16 must be rotated as far until the corresponding surface 20 abuts the abutment surface 23rd By spring 41, the contact surface 23 is always pulled against the surfaces on the periphery of the control wheel 16th Since the turning of one surface to the next, the tension spring 41 is stretched and relaxed again, is formed in each surface a tactile detent.

4. Tighten the second set screw 24th

p0034The angle ß chosen so that it is less than 90 ° and greater than the angle of self-locking the material pairing of the wall 31 of the essay 3 and the spacer plates 32nd

p0035The self-locking describes the mechanics caused by frictional resistance to the displacement of two adjoining body. Here, is referred to as self-locking angle of the angle of the inclined plane, is present in the static friction. If the angle of self-locking exceeded, there is friction and the two bodies are therefore no longer self-locking. The size of the angle of self-locking is dependent on the surface roughness of the material pairing.

p0036The paper 3 is thus again pulled with its contact surface 23 against the face 20 of the adjusting wheel 16 and simultaneously with its wall 31 against the spacer plates 32 and this against the wall 30 on the appendage 14th Thus, there is a positive connection. Would the second clamping screw 24 transverse to the weft direction, ie at 90 degrees to the surfaces 30 and 31, would include a purely frictional connection, because not drawn in this case, the top 3 with its contact surface 23 against the face 20 of the adjusting wheel 16 would. If the angle ß is chosen to be smaller than the angle of self-locking - so therefore within the self-locking - the material pairing of the wall 31 of the essay 3 and the spacer plates 32, so also only a frictional connection would be present, as in this case, the paper 3 is not drawn with its contact surface 23 against the face 20 of the adjusting wheel 16th

5. Tightening the first clamping screw 12th

p0037The points 1 and 2 and the points 4 and 5 in handling the adjustment can also be performed in reverse order.

p0038The scope mount can be performed basically in two parts (not shown in the figures). This means that the area of ​​the hinge with the front half-shell 5 and the area of ​​the actuating wheel 16 with the rear half-shell 6 have no connection. Both areas then sit separately on the Picatinny rail or 4 are connected to the weapon according to the mounting method.

p0039In another not shown in the Figures Embodiments of the invention are the extension 14 with the circular spigot 15 and the thumbwheel 16 not on seen in the weft direction rear end of the assembly, but at their front end. Accordingly, then the compound is tapered at the rear end of the assembly.

p0040The setting wheel 16 and the taper 8 sitting in the exemplary embodiment of the invention as seen in the weft direction right side of the scope mount. These elements can also be arranged on the left side.

p0041In another, not shown in the figures, the taper 8 part of the article 3 and the conical recess 10 in a row to be the part of the body. 2

p0042In another variant of the extension 14 with the circular spigot 15 may be part of the paper. 3 The internal thread 29 for the second clamping screw 24 is located in this embodiment in consequence of which in the base body second
