Abstract

A mounting apparatus is disclosed for attaching a sighting device onto a weapon. The mounting apparatus has a rail disposed on part of the weapon in a longitudinal direction. The rail has a pair of longitudinally extending opposed sides and a longitudinally extending first attachment element on each of the opposed sides. A removable mounting base has a pair of longitudinally extending side edges and a longitudinally extending second attachment element on each side edge. Each second attachment element is complimentary to a corresponding one of the first attachment elements. The mounting base is slidingly and longitudinally engaged with the rail via the complimentary first and second attachment elements. The mounting base is formed of at least two parts which are slidable against one another in a transverse direction. A spring mechanism produces a spring force and is arranged to bias the two parts of the mounting base into engagement with the rail. The spring force is overcome by manually squeezing the two parts to release the mounting base from the rail.

Description

The invention relates to a mounting device for attachment a telescopic sight or the like on one on one Firearm attached or trained longitudinal profile rail, the one on each side pointing outwards longitudinal groove or a longitudinal web each has a removable mounting base engages longitudinally displaceably with a web or a groove, the or each on one of the side edges of the mounting base are formed, as in claim 1 outlined.

US 3 877 166 and EP become prior art 0 444 300 A2.

For the adjusted mounting of riflescopes or the like Weapons have quite different types of assembly facilities. Common to all is the fundamental endeavor the mounted riflescope as immovable as only possible to attach to the weapon so it never changes its position relative to the weapon.

In the case of elaborate hunting weapons, mostly handcrafted ones are used Assembly facilities used, the most accurate have manufactured, complicated surfaces. at Sporting weapons and military rifles, on the other hand, are usually drawn simpler and more robust assembly facilities that go back to the basic form of so-called slide-on installation. The invention is such an assembly device.

With such a slide-on installation, there is one on the weapon dovetail-like longitudinal profile rail attached or trained; and on the scope or the like a removable foot or mounting base with a nut profile, that on the longitudinal rail of the weapon with little Game is postponed.

The longitudinal profile rail can be on the top of the gun be attached so that their surface with normal stop with a horizontal direction of fire. But it can also be attached to the side of the weapon be so that their surface is normal stop runs approximately vertically; or elsewhere and coupled to the weapon, such as on a machine gun mount. The length of the longitudinal mounting rail can only be a few centimeters. But it can also be significant be longer.

A clamping device, in the simplest case a clamping screw, penetrates across the mounting base and serves to to clamp this on the dovetail. The The shaft of the clamping screw is between the mounting base and the longitudinal mounting rail arranged that the Position of the telescopic sight in the longitudinal direction of the weapon always is reliably reproducible. Such an assembly facility can be seen, for example, in US-A-3 887 166 (Ward). This known assembly device is advantageous because it has a small size. Your disadvantage lies however in the cumbersome postponing and finding out the correct mounting position, as well as in the necessarily quite high manufacturing accuracy.

It is also possible to split the mounting base lengthways and one part relative to the other from the engagement with the longitudinal profile rail to move out. In this case the mounting base does not have to be on the Longitudinal profile rail can be pushed on, but can with staggered parts placed anywhere on this become. When the parts return to their original position, then they engage in the longitudinal profile rail and get stuck on this Such an assembly facility can be seen in EP 0 444 300 A2 (Repa). In this publication is a long one off-center Shown pivot lever that swivels near one end is mounted on part of the mounting base. The short end of the swivel lever is with the other part of the Assembly base connected via a knee joint mechanism, which allows this other part with great External force against the longitudinal mounting rail, i.e. in Towards the first part. Because the toggle mechanism is kinked in its rest position he a force in the direction of a backward movement of the movable Part. It is therefore a powerful disc spring package provided that this backward movement compensated and at the same time the swivel lever in the holds the buckled position of the toggle mechanism.

The latter assembly device is advantageous because it can be put on and taken off quickly, and because the disc spring package manufacturing inaccuracies can compensate. However, their disadvantage lies in the bulky version because of the long swivel lever is required.

The invention is based on this prior art based on the task, the known assembly facilities to improve in that their benefits are effective remain, but their disadvantages are eliminated as far as possible.

This object is achieved by the subject of claim 1 solved, so that in an assembly device, which is similar to that of EP 0 444 300 A2 (Repa), dispense with any mechanism for tightening and instead the clamping force for clamping of the two parts of the mounting base on the longitudinal mounting rail is supplied by a spring arrangement, their spring force for removing and fitting the mounting base from or onto the longitudinal mounting rail from the Fingers of the user can be overcome, that is about 5 kg not significantly exceeds (claim 1).

Here comes with a tradition going back more than a hundred years broken, according to the one corresponding to the mounting base Mount with the rifle in the transverse direction must be positively connected to relative shifts of mount and weapon in the transverse direction below exclude all circumstances. The invention connects through the mounting base with the longitudinal profile rail Engaging element that only with a limited and by external forces completely releasable spring force engaged is held. The relative displacement in the transverse direction is quite possible.

So far it was a prerequisite for every assembly facility, the scope of the scope under all circumstances to keep on the gun. If the gun from the high seat fell down, then for example the buttstock cancel, but the riflescope had to stay put. According to the invention it has now been recognized that from a certain Impact balance on the riflescope, night aiming device o. Damage occur that requires at least one repair and immediate reuse impossible make: about when a rifle with night aiming device falls two meters on the pavement. Then the night target device then shows no picture more. It therefore does not need to be attached to the rifle to stay. Rather, it is possible that the inertia of the falling night target device the spring arrangement according to the invention consuming energy so loaded that it releases the night target device braked. It is therefore quite conceivable that the inventions. proper installation when the rifle falls mounted accessory this just by being released protected from the weapon from damage by a conventional Assembly would have been inevitable.

Another advantage is that according to the invention all long Clamping lever and also the great machining accuracy inaccuracies are eliminated since the spring arrangement is able to compensate easily. At most there is one Set screw required to the clamping force of the spring assembly adjust.

However, the assembly device according to the invention is preferred the positive connection between the longitudinal profile rail and the mounting base to prevent it from slipping to prevent due to external forces (claim 2). With the two known assembly devices mentioned at the beginning is the mounting base with such a clamping force clamped on the longitudinal profile rail that this cannot be overcome without damaging the parts. Though is also a positive fit in US-A-3 877 166 (Ward) Connection shown by a cross bolt, but this only serves to position the assembly base, not its hold against slipping in the longitudinal direction the weapon. This slipping is in the state of the Technology sufficiently prevented by the clamping, so that the present, additional, form-fitting Hold intervention is not required.

In contrast, in the invention there is training on the mounting base preferred, the form-fitting in a transverse groove Longitudinal rail engages because of the clamping effect the spring force is not always sufficient to the mounting base with the rifle he carried To prevent slipping.

However, it should be noted that the spring force of the Assembly device according to the invention is usually sufficient around a rifle scope or the like with normal handling to hold the gun firmly on it. The As a rule, user will not make a difference between the assembly according to the invention and one of the beginning determine the mentioned assembly from the state of the art, except that the mounting base is clear is smaller, and that the clamping lever is missing and thus the Handling is simplified.

It is possible on both sides in the longitudinal mounting rail form a protruding edge in which the engage both parts of the mounting base from the inside, by being pushed apart by the spring force. Extensions of these parts by the fingers of the Users can be taken to need to lose weight of the mounting base only to be compressed. At least a bevel on the two parts can do this ensure that the mounting base is only on the longitudinal profile rail needs to be pushed open. The in the Bevels engaging edges of the longitudinal profile rails press the two parts of the mounting base under Overcoming the spring force together. In such a trough-shaped trained longitudinal profile rail can but collect dirt easily, especially when on the Top of the gun is attached horizontally.

The two side edges of the longitudinal profile rail are therefore preferred encircled from the outside, because then an insufficient Seat due to the contamination of the longitudinal profile rail is rather excluded. The spring force causes then that the two parts of the mounting base on top of each other to be charged. In addition, there is one Part guided in the other and stands laterally above this forming a handle over. Will with one finger pressed on this handle while another finger supports the other part, then be overcome the two engagement edges (with one each Groove or a web) from the side edges of the longitudinal profile rail (each with a web or a groove) moved away.

Furthermore, the part that is equipped with the handle is referred to as an indentable part while the other part is called the non-indentable part becomes. The guidance of the pushable part in the non-pushable Part ensures that the two parts assembled mounting base is sufficiently longitudinally stable.

A particularly simple training on the mounting base is a cross pin, preferably a round cross pin, which at the mounting base is parallel to a transverse groove extends and engages in these. It is possible arrange the cross pin in the push-in part. It is but more appropriate, the cross pin in the non-depressible Arrange part of the mounting base, since then there is no danger there is movement of the depressible part hindered by the abrasion of the cross pin on the transverse groove will (claim 3).

The cross pin is preferably next to the push-in Partly arranged, i.e. in the longitudinal direction of the longitudinal profile rail seen, in front of or behind the impressible Part so that the cross pin is not the pushable part enforce needs (claim 4).

For a hunting rifle that was used by only one shooter and is used with a single scope it is sufficient, only one in the longitudinal profile rail Arrange the transverse groove, as in US-A-3 877 166 (Ward) is shown. In the assembly device according to the invention However, are preferably several transverse grooves in the Longitudinal profile rail formed (claim 5).

So the mounting base with the cross pin in each most suitable transverse groove are used. It It is possible to use a riflescope in the best possible way Arrange eye relief when the shooter has a thick shatterproof vest and winter clothing. It can also any other facilities for one and the same rifle is intended, such as a night target, a red dot sight, a sight for special ammunition, about a grenade launcher visor or the like. These can, depending according to length and weight, one or more mounting bases have and with the cross pin of or each mounting base each inserted in a suitable transverse groove become.

It is according to a further embodiment of the invention The longitudinal profile rail is particularly advantageous to extend forward, approximately to the end of the fore-end or even to the mouth. An optical or illuminated one Grain (marked with "eagle's eye" for marksmen) can be put on as well as a combination from optical riflescope and image intensifier or Image converter to make a high performance night target device at night or a thermal imaging night target to have. These often long devices can then be used two or even with several mounting bases become. It is put on by means of a bevel relieved at the lower edge of the push-in part, that of the engaging edge of the longitudinal profile rail is facing. The target device then only needs this Splint to be pushed open. However, losing weight a hand is required for each base, which is the push-in Part. But it is also possible that part of a catch device or locking device that can be pushed in assign to keep it depressed. In In this case the mentioned bevel is not necessary.

Weapons have also been used for a few decades Precision parts in a die casting process. there either zinc is used (because of the low melting point with sufficient strength) or plastic. It offers itself, at least the longitudinal profile rail also inexpensive to manufacture from such a material (Claim 6).

As such, these materials have the disadvantage that they are under give way to a too high surface pressure: if one for example, into the bore of a zinc workpiece Steel pin with a press fit, so you can Pull the steel pin out of the hole effortlessly a day later, because it is only in a slight transition fit sits in the hole. The material has recrystallized to the extent that those warped by tensions Crystal structures have reoriented themselves. Known Mounting 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 give way.

A plastic rail would be special for a rifle then an advantage if the longitudinal profile rail is at least about the length of the fore-end would have to extend at the front, for example around an equipment rack for to form a universal use. A plastic rail could be even easier than one Be light alloy rail.

Only the assembly device according to the invention enables surprisingly the use of zinc or Plastic for the longitudinal profile rail. Because the spring force, with which the parts of the mounting base engage pressing with this rail is strictly defined. Even in the case of unfavorable tolerances and unfavorable settings remains the spring force, which is the clamping effect causes about the same order of magnitude. A Thread clamping, on the other hand, can occur in the event of an unfavorable setting cause a very significant increase in the clamping force, that even until the clamping screw is torn off can lead. A spring device is required their spring force changes approximately linearly to the spring travel, and this to a small extent; not a disc spring package like in EP 444 300 A2 (Repa). A spring device one or two preloaded compression coil springs Wire has proven itself.

In order to avoid harmful surface pressures, the Dimensions are of course not too small and are in generally be larger than with previous assembly facilities. As the width of a longitudinal profile rail Plastic, measured transversely to the longitudinal direction of the rifle, So the distance between the two engagement edges has a measure proven from 20 to 25 mm. The engagement length of the mounting base is about the same measure. The material of the mounting base is preferably light metal, such as an aluminum alloy, since the support of the spring device can give higher surface pressures than they permissible for plastic or zinc.

All figures show the same assembly device that in about 1.5 times magnification is shown. All reference numbers denote throughout in all figures same parts.

Incidentally, terms such as "top", "front" u. like. assuming the normal position of a rifle, where the shot direction is horizontal. "Front" points in the direction of the shot.

The mounting device comprises a longitudinal profile rail 1 made of plastic, which is preferably made by injection molding, about a reinforcement made of glass fibers or the like. sprayed and has: a solid lower part 2, the has an approximately flat rectangular cross section and on the Top of a rifle is mountable; an additional two Upper parts 4 on the two sides of the lower part 2 sit and each have a square cross-section, that in the form of an isosceles triangle is extended on the outside, in such a way that the free tips these cross-sectional triangles each have longitudinal engagement edges 3, 5 form, each over the lower part 2 survive to the outside. Between the two tops 4 an upwardly open longitudinal groove 7 is recessed. This serves to save weight and also helps a reasonably uniform wall thickness in the longitudinal profile rail 1 maintain so that casting errors avoided become. In the rail 1 are transverse to their longitudinal extent introduced a plurality of transverse grooves 9, which are extend through the upper parts 4 of the rail profile and do not reach all the way down to the bottom of the longitudinal groove 7. The cross section of these transverse grooves 9 has the shape of a squat, lying rectangle.

The rail 1 extends from one point above the front end of the piston neck up to one point the front end of the forearm of a rifle and is only attached in two places. On one of these The rail 1 is set in all three coordinate directions fixed on the other only in two coordinate directions, similar to a road bridge with a fixed one and a loose support to relative thermal expansion to be able to carry on to the rifle without warping.

On the rail 1 is a mounting base 11, which consists of a pushable part 15 and a non-pushable Part 13 is formed. The non-crushable part 13 has a claw 17, 19 on each side, which are complementary to the engaging edge 5 of the rail 1 and encompasses this edge 5. Here is the a 17 of the claws 17, 19 in the longitudinal direction (direction of Extension of the rail 1) is shorter than the other Claw 19. The area of claw 19 penetrates Embossed cross pin 21, which is attached to the mounting base 11 in a transverse groove 9 with little or no Game intervenes.

The depressible part 15 is movable in the transverse direction guided part 13. It sticks out of one Long side of the non-crushable part 13 out - here on the side of the engaging edge 5 - and there has one Handle 23 on the side of the mounting base 11 protrudes and can be pressed inside by hand.

There are two surfaces within the mounting base 11 of the two parts 13, 15 opposite, between which two Compression springs 25 are arranged. A limit pin 27 which is hammered into the non-depressible part 13, engages in the push-in part 15 in its end position and limits its movement.

As can be seen, the push-in part 15 becomes one Pressed the rest position, in which the handle 23 from the non-depressible Part 13 protrudes sideways. On the opposite Side is on the push-in part 15 downward, lateral longitudinal web formed, in the side facing the rail 1, an engagement groove 29 is formed, which is complementary to the engaging edge 3 is formed and encompasses them. In the rest position of the pushable part 15 becomes the engagement groove 29 can be seen with the force of the compression springs 25 against the Engagement edge 3 pressed so that the mounting base 11th then held essentially immovable on the rail 1 becomes. By pressing the handle 23 with the Fingers of one hand with another finger on the non-depressible part 13 or the part mounted thereon Rifle scope or the like holds the engagement groove 29 moved out of engagement with the engagement edge 3 and then the mounting base 11 can be removed from the rail. The same applies to fitting the mounting base 11 on the rail 1.

On the flat, upper surface of the mounting base 11 can the scope or device to be mounted is attached become.

The mounting base 11 is clamped on the rail 1 only with the spring force of the compression springs 25. So far the frictional force resulting from the clamping is not sufficient to hold the mounting base 11 in the longitudinal direction, the cross pin 21 provides this hold, which in a the transverse grooves 9 engages.

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 engaging edges 3, 5 and the claws 17, 19 results the maximum surface pressure on the rail 1. This is dimensioned so that the plastic of the rail 1 through the engagement of the claws 17, 19 and the engagement groove 29 undergoes no permanent deformation.

In the mounting base 11 shown, its position or Alignment chosen so that the handle 23 at a right-handed shooter on the left and one Left-handed as a shooter is on the right, so that this handle 23 are pressed in with the thumb of the utility hand can if the other hand holds the rifle under the forearm holds.
