Mounting device for fitting a telescopic sight to a fire arm

The invention relates to a mounting device for mounting A target telescope, or the like, on a line connected to a Weakening weapon, Which on each side points outwards to the outside Or a longitudinally extending web Into which a removable mounting base is mounted Is longitudinally displaceably engaged with a web or a groove, Respectively, on one of the lateral edges Of the mounting base, as in claim 1 Outlined.

The prior art is described in US Pat. No. 3,877,166 and EP 0 444 300 A2.

For the adjusted holding of target telescopes or the like Weapons, there are quite different types of mounting devices. To all is the basic endeavor together, The mounted target telescope is as immovable as Only possible to attach to the weapon to allow it Its relative position to the weapon never changes.

In the case of elaborate hunting weapons, craftsmanship is usually used Assembly devices that are most accurate Produced, complicated surfaces. At the Sports guns and military guns, on the other hand, are usually drawn Simpler and more robust assembling devices which To the basic form of the so-called postponement assembly. The invention is such a mounting device.

In such a postponement installation, the weapon is a Dovetail longitudinal profile rail Or formed; And the target telescope or the like A removable foot or mounting base with a nut profile, Which is applied to the longitudinal profile rail of the weapon with a low profile Game is postponed.

The longitudinal profile rail can be on the top of the gun So that their surface is at normal stop With horizontal shooting direction horizontal. It can also be attached to the side of the gun , So that its surface at normal stop Approximately vertical; Or in any other place And coupled to the weapon, such as on a MG vehicle fender. The length of the longitudinal profile rail can be Only a few centimeters. But it can also be significant Be longer.

A clamping device, in the simplest case a clamping screw, Crosses the mounting base transversely, To clamp this on the dovetail. Of the Shank of the clamping screw is thus between the mounting base And the longitudinal profile rail, in that the longitudinal profile rail, Position of the target telescope in the longitudinal direction of the weapon always Reliably reproducible. Such a mounting device Can be seen, for example, in US-A-3,887,166 (Ward). This known mounting device is advantageous because It has a small size. Their disadvantage lies But in a cumbersome postponement and discovery The correct mounting position, as well as in the necessary Quite high manufacturing accuracy.

It is also possible to longitudinally divide the mounting base and The one part relative to the other from the engagement with Of the longitudinal profile rail. In this case The mounting base must not be extended in the longitudinal direction to the Longitudinal profile rail can be slipped, but can be fitted with Offset parts at any location will. When the parts return to their initial position, Then engage the longitudinal profile rail And clamp on it. Such a mounting device Can be seen in EP 0 444 300 A2 (Repa). In This print is a long-term stored Pivot lever pivoted near its one end Is mounted on a part of the mounting base. The Short end of the pivoting lever is connected to the other part of the Mounting base via a knee-jointing mechanism, Which makes it possible to carry this other part with great Force from the outside against the longitudinal profile rail, that is, in FIG Direction against the first part. Because the toggle mechanism In its resting position It applies a force in the direction of a backward movement of the movable Part out. It is therefore a powerful plate spring pack Provided that this backward movement Compensated at the same time the pivot lever in the Bent-over position of the toggle lever mechanism.

The last-mentioned mounting device is advantageous, Because it can be quickly set up and removed, and Because the plate spring package manufacturing inaccuracies Can compensate. Their disadvantage, however, lies in the Bulky design, because of the long lever is required.

The invention is based on this prior art The object on which the known assembly devices are based To improve their advantages effectively But their disadvantages are avoided as far as possible.

This object is achieved according to the invention by the object Of the claim 1, that is to say, in the case of a mounting device, Which is similar to that of EP 0 444 300 A2 (Repa) To eliminate any mechanism for clamping And instead the clamping force for clamping Of the two parts of the mounting base on the longitudinal profile rail From a spring arrangement, Whose spring force is used to remove and mount the mounting base From or to the longitudinal profile rail from the Fingers of the user, ie about 5 kg Is not significantly exceeded (claim 1).

Here, with a more than hundred years old tradition Broken, according to the one corresponding to the montageockel Support with the rifle in the transverse direction absolutely Must be connected positively to form relative displacements Of bracket and gun in the transverse direction Circumstances. The invention relates The mounting base with the longitudinal profile rail through one Engaging element which is provided only with a limited and through External forces Is maintained. The relative displacement in the transverse direction Is quite possible.

To date, it has been a prerequisite for each assembly device, Under all circumstances the stop of the target telescope On the weapon. When about the weapon from the high seat Fell, then for example the background But the target telescope must remain seated. According to the invention, it has now been found that, starting from a certain Impact force on the target telescope, Damage occurring at least requires repair And the immediate re-use is impossible Make: if a gun with an aftertime device out Two meters high on the street pavement. Then The Nachtzielgerät does not show an image more. It does not need to be mounted on the rifle to stay. Rather, it is possible that the mass inertia force Of the falling night sender The spring arrangement according to the invention is energy-consuming Is loaded so as to release the after-braking device in a decelerated manner. It is, therefore, quite conceivable that the invention- Assembly according to the invention when the rifle is dropped Mounted accessory this just by its freikommen From the weapon from damage that is caused by a conventional Assembly would have been unavoidable.

It is also advantageous that, according to the invention, all long, Clamping lever and also the great machining accuracy Since the spring arrangement is capable of detecting inaccuracies Without further adjustment. In any case, one Adjusting screw required to adjust the clamping force of the spring arrangement .

However, the mounting device according to the invention preferably prefers The form-locking connection between the longitudinal profile rail And the mounting base to its slipping Due to external forces (claim 2). In the two known mounting devices mentioned at the outset Is the mounting base with such a clamping force Is clamped on the longitudinal profile rail in such a way that the latter is fixed Without damaging the parts. Of course US Pat. No. 3,877,166 (Ward) also provides a positive-locking Connection by a transverse bolt, But this only serves to position the mounting bracket, Not its hold against slipping in the longitudinal direction The weapon. This slipping is carried out in the state of the Technique sufficiently prevented by the clamping, so That the additional, positive, Holding engagement is not required.

In the case of the invention, on the other hand, an embodiment is provided on the mounting base Which are positively engaged in a transverse groove of the Longitudinal profile rail, because the clamping effect due to the fact Of the spring force is not sufficient in every case The mounting base with the rifle carried by him To prevent slipping.

However, it is pointed out that the spring force of the According to the invention, as a rule, To a target telescope or the like in normal handling Of the weapon immovably on this. Of the Users will therefore generally not make a difference Between the assembly according to the invention and one of the initially described Mentioned assembly from the prior art, Except that the mounting base is clear Is smaller, and the clamping lever is missing and thus the clamping lever Handling is simplified.

It is possible in the longitudinal profile rail on either side To form a protruding edge into which the Both parts of the mounting base engage from the inside, By being pushed apart by the spring force. Extensions of these parts by the fingers of the Users can be taken for weight loss Of the mounting base can only be compressed. At least A chamfer on the two parts can be used for this purpose Ensure that the mounting base is placed only on the longitudinal profile rail To be pressed. The in the Edges of the longitudinal profile rails Press the two parts of the mounting base Overcoming the spring force. In such a trough-shaped Shaped longitudinal profile rail can extend But easily collect dirt, especially when they are at the Top of the gun horizontally.

The two lateral edges of the longitudinal profile rail are therefore preferred From outside, since then an insufficient Seat due to contamination of the longitudinal profile rail Is rather excluded. The spring force causes Then the two parts of the mounting base are aligned To be loaded. In addition, the one is Part in the other led and stands over this sideways With the formation of a handle. Comes with a finger Pressed on this handle, while another finger The other part, then are overcome Of the spring force the two engagement edges (each with one Groove or a web) from the lateral edges of the longitudinal profile rail (Each with a web or a groove).

Next, the part that is equipped with the handle Is referred to as a compressible part The other part is referred to as a non-compressible part becomes. The guide of the push-in part in the non-compressible Part ensures that the one from both parts Is sufficiently long-sta- ble.

A particularly simple training at the mounting base is A transverse pin, preferably a round transverse pin, which, On the mounting base parallel to a transverse groove And engages therewith. In this case, To arrange the transverse pin in the compressible part. It is But more convenient, the transverse pin in the non-compressible Part of the mounting base, since then not the danger That the movement of the push-in part By the scrubbing of the transverse pin at the transverse groove (Claim 3).

In this case, the transverse pin is preferably adjacent to the compressible Part, ie in the longitudinal direction of the longitudinal profile rail Seen, before or behind the crushable Part, so that the cross pin does not allow the crushable part (Claim 4).

At a hunting gun, only by a single shooter And is used with only a single aiming telescope Sufficient in the longitudinal profile rail to have only one As described in U.S. Patent No. 3,877,166 (Ward). In the assembly device according to the invention But are preferably several transverse grooves in the Longitudinal profile rail (claim 5).

Thus the mounting base with the cross pin can be inserted into the respective Most suitable cross-section. It It is thus possible to obtain a target telescope in the optimum range If the shooter has a Thick shards and waistcoats. It Can also be any other facilities for a The same rifle, for example, A light-point target, a visor for special ammunition, For example, a grenade head sight, or the like According to length and weight, one or more mounting bases And with the transverse pin of the or each mounting base Each inserted into a suitable transverse groove will.

Here, according to a further embodiment of the invention Of particular advantage, the longitudinal profile rail To the front, approximately to the end of the forehead Or even to the mouth. An optical or illuminated Grain (referred to as "eagle's eye" for sports rifles) Can be set up as well as a combination From optical sight tube and image intensifier or To-night converter Or a thermal imager is available have. These often long-developing devices can be used with Two or even with several mounting bases will. This is achieved by means of a chamfer At the lower edge of the push-in part, Which corresponds to the engagement edge of the longitudinal profile rail . The target device then only needs this Rail. However, for losing weight For each pedestal a hand is required, which is the crushable Part. However, it is also possible to use the A part which can be pressed in To keep it depressed. In In this case, said chamfer is not required.

For a few decades, we have also been building weapons Precision parts in a die-casting process. At the same time One uses either zinc (because of the low melting point With sufficient strength) or plastic. It At least the longitudinal profile rail is also suitable From such a material (Claim 6).

As a matter of fact, these materials have the disadvantage that they can be used under Too high a surface pressure: if For example into the bore of a workpiece made of zinc If the steel pin is press-fitted, this can be done The steel pin can be easily removed from the hole one day later, Because it is then only in a slight transitional fit In the bore. The material has become Are recrystallized to the extent that the stresses are strained Crystal structures have reoriented themselves. Known Assembly devices with a longitudinal profile rail Plastic or zinc can therefore hardly be used. With you It is practically inevitable that a very High clamping force acts on the material of the rail and This causes them to yield.

In the case of a rifle, a plastic rail would be particularly advantageous Then it is of advantage if the longitudinal profile rail itself At least over the length of the forefoot Front, for example around a device carrier for A universal use. A plastic rail Could be even lighter than one Light metal rail.

Only the mounting device according to the invention makes possible In a surprising manner the use of zinc or Plastic for the longitudinal profile rail. For the spring force, With which the parts of the mounting base engage With this rail is strictly defined. Also in case of unfavorable tolerances and unfavorable setting The spring force holding the clamping action remains Is of the same order of magnitude. A Thread clamping, on the other hand, can result in an unfavorable setting A very considerable increase in the clamping force, Even up to the tearing of the clamping screw can lead. A prerequisite is a spring facility which: Changes its spring force approximately linearly to the spring travel, and this To a small extent; Not a plate spring pack like In EP 444 300 A2 (Repa). A spring device out One or two preloaded compression coil springs Wire have proved their worth.

In order to avoid harmful surface pressures, the Dimensions of course will not be too low and will be in Can generally be larger than in previous assembly devices. The width of a longitudinal profile rail Plastic, measured transversely to the longitudinal direction of the gun, Ie as a distance between the two engagement edges, has become a measure From 20 to 25 mm. The operating length of the mounting base Is approximately the same. The material of the mounting base Is preferably light metal, such as an aluminum alloy, Since in the support of the spring device Higher surface pressures than they do For plastic or zinc.

The invention is described with reference to an exemplary embodiment and Of the accompanying schematic drawing. In the drawing: FIG.<dl tsize="6"><dt>FIG</dt><dd>A longitudinal section through a mounting device Of the invention, the bearing to be carried by the mounting base Target distance tube, or the like, for better clarity Is omitted,</dd><dt>FIG</dt><dd>5 shows a side view of the mounting device of FIG. 1, viewed from the direction Z (see FIG. 6),</dd><dt>FIG</dt><dd>12 is a plan view of the assembly device of FIG Figures 1,</dd><dt>FIG</dt><dd>The section AA in FIG. 2,</dd><dt>FIG</dt><dd>The section BB in FIG. 2,</dd><dt>FIG</dt><dd>The section CC in FIG. 2,</dd><dt>FIG</dt><dd>The section DD in FIG. 2, and FIG </dd><dt>FIG</dt><dd>The mounting device of FIG. 1, obliquely from above Seen.</dd></dl>

All the figures show the same assembly device, which is shown in FIG About 1.5 times magnification. All references Throughout the figures same parts.

Moreover, terms such as "top", "front" From the normal stroke position of a rifle, Wherein the weft direction is horizontal. "Front" In the weft direction.

The mounting device comprises a longitudinal profile rail 1 Made of plastic, which is preferably produced by injection molding, For example on a reinforcement of glass fibers or the like. injected , And comprising: a solid lower part (2) Has an approximately flat rectangular cross-section and, on the Top of a rifle mountable; two additional 4, which are arranged on the two sides of the lower part 2 And each have a square cross-section, In the form of an isosceles triangle Externally, in such a way that the free peaks Of these cross-section triangles each have engaging longitudinal edges 3, 5 which extend over the lower part 2 in each case To the outside. Between the two tops 4 An upwardly open longitudinal groove 7 is eliminated. These Is designed to reduce weight, A uniform uniform wall thickness in the longitudinal profile rail 1, so as to avoid casting defects will. Into the rail 1 are transverse to their longitudinal extension A plurality of transverse grooves 9 which extend Extend through the upper parts 4 of the rail profile and Do not extend completely down to the base of the longitudinal groove 7. The cross-section of these transverse grooves 9 takes the form of a cross-section Squat, lying rectangle.

The rail 1 extends from a position above that Front end of the piston neck to a point above The front end of the front shaft of a gun and Is only fixed in two places. On one of these The rail 1 is in all three coordinate directions , On the other only in two coordinate directions, Similar to a road bridge with a fixed And a loose support to reduce thermal elongations relative To the gun without rejecting it.

On the rail 1 is seated a mounting base 11, which consists of a Compressible part 15 and a non-compressible part Part 13 is formed. The non-depressible part 13 Has a claw 17, 19 on either side of each side, Which is complementary to the engaging edge 5 of the rail 1 And encompasses this edge 5. The A 17 of the claws 17, 19 in the longitudinal direction (direction of the Extension of the rail 1) is shorter than the other Claw 19. The area of ​​the claw 19 penetrates In cross-pin 21, which, when the mounting base is mounted 11 in a transverse groove 9 with little or none Game intervenes.

The pushable part 15 is movable in the transverse direction Non-compressible part 13. It stands out from one The long side of the non-compressible part 13-here On the side of the engagement edge 5 - and points there Handle 23 which extends laterally out of the mounting base 11 And can be pressed into the interior thereof by hand.

Within the mounting base 11 there are two surfaces Of the two parts 13, 15, between which two Pressure springs 25. A restriction pin 27, Which is inserted into the non-compressible part 13, Engages the compressible part 15 in its end position And limits its movement.

As can be seen, the push-in part 15 is inserted into one Rest position in which the handle 23 is released from the non-compressible Part 13 protrudes laterally. On the opposite Side is engaged with the push-in part 15 Downwardly projecting lateral longitudinal web, In its side facing the rail 1, an engagement groove 29, which is complementary to the engagement edge 3 and encompasses the latter. In the resting position Of the push-in part 15, the engagement groove 29 becomes Evident with the force of the compression springs 25 against the Engaging edge 3, so that the mounting base 11, Then held substantially immovably on the rail 1 becomes. By pressing the handle 23 with the Finger of a hand holding a finger on the other hand Non-compressible part 13 or the mounting part mounted thereon Target telescope or the like, the engagement groove 29 is moved out of engagement with the engaging edge 3 and Then the mounting base 11 can be removed from the rail. The same applies to the mounting of the mounting base 11 to the rail 1.

On the flat upper surface of the mounting base 11, The target telescope to be mounted is attached will.

The clamping of the mounting base 11 on the rail 1 takes place Only with the spring force of the compression springs The frictional force resulting from the clamping does not For holding the mounting base 11 in the longitudinal direction, The transverse pin 21 provides this stop, which is inserted into a Of the transverse grooves 9.

The length of the two claws 17, 19 is approximately equal to that Length of the engagement groove 29. From the shorter of these lengths, The spring force of the compression springs 25 and the geometry The engagement edges 3, 5 as well as the claws 17, 19 The maximum surface pressure on the rail 1 Is dimensioned in such a way that the plastic of the rail 1 passes through the guide rail The engagement of the claws 17, 19 and the engagement groove 29 No permanent deformation occurs.

In the mounting base 11 shown, Orientation is selected in such a way that the handle 23, A right - handed person as a shooter on the left and at one Left-hander as shooter right, so that this handle 23 with the thumb of the hand Can, if the other hand the gun under the forefront .
