Description

The The invention relates to an adapter for mounting a device, in particular a Harris bipod, on a protruding splint or paternal splint, especially a Weaver or Picatinny rail, a rifle, a crossbow or the like, wherein the device at the top bearing surfaces and Means, in particular a tie rod for tightening the device to the Father rail has.

in the Following is from the normal position of a rifle and of it attached device in Form of a bipod gone out, d. h., with horizontal axis of the soul and horizontal transverse axis. In this context, "above" also means "to the rifle down "and" down "also" off the rifle ". There are but also other devices with similar mechanics such as B. this bipod conceivable and these devices do not need to to be attached to the rifle.

The Harris bipod has long been known for equipping benchrest rifles, military Sniper rifles and absolutely all rifles, providing a safe, quiet circulation to deliver a precision shot require. A variety of shooters has such a Harris bipod, and almost every rifle can equipped with such become.

A similar adapter for attaching a bipod for a rifle is in the US 2005/018 85 88 A1 and the US 2005/018 85 97 A1 disclosed.

This Harris bipod features two elongated, padded, to the horizontal center line slightly inclined contact surfaces. Between the bearing surfaces are two essentially vertical, strong fingers arranged lie side by side in the transverse direction and at the upper end depending a pin is attached. The pins are horizontal, are arranged in alignment and facing each other. The fingers can by means of a thumbscrew be driven up, where they are against the action of a spring can move apart, or down, where then the fingers run into a backdrop, the They and thus also the pins pressed together and their movement apart impossible power.

At the The fore-end of the rifle is on both sides and symmetrical to its longitudinal axis one counter surface each. Between the mating surfaces sits a block that has a transverse bore. The block can z. B. sitting on a slide in a central, horizontal, taken in dovetail longitudinal rail or mother rail is inserted and screwed there, or can z. B. be screwed directly onto the shaft.

At the Attaching the bipod, its fingers are driven upwards and pressed against the action of the spring until the pins on both sides the cross-hole of the block are located. Then the fingers are released, so that the pins come into the cross hole. Last is the thumbscrew attracted, causing the fingers down with the help of a lever be moved and in turn the block and the mating surfaces with pull down until bearing surfaces and counter surfaces get in full circulation.

Of the special advantage of this known bipod is that when not in use can be removed and needs to be attached only when needed, so that z. B. a shooter Several rifles can be used to attach a bipod are suitable, but this requires only a single bipod. One Disadvantage, however, is that a protruding pin on the guns must be firmly attached. For reasons the strength is the loosening of the block is not advisable, as the thread or the thread to its attachment otherwise could turn out; In any case, this tool and some skill is required. Thus, as a rule, the protruding block remains on the rifle, where he is obstructive, unless the bipod is attached.

Usually the bipod is as far as possible attached to the front of the rifle. But sometimes the terrain, in a sniper wants to post, another attachment site desirable make or it is about desired a laser rangefinder in front of the bipod into the mother rail insert. Such an arrangement is then but from structural establish not possible.

In younger Time is the attachment of additional equipment (sighting device, laser rangefinder, Night destination device, Headlight, additional handle etc.) has become increasingly important so that special, protruding, relatively wide rails or father rails (so-called Picatinny or Weaver rails) at the front of all kinds of weapons, even at the bottom of the shaft or hand guard. It's not just new rifles provided with such rails, but it can also be existing rifles equipped with father rails. Since these rails are relatively wide and quite long, hinder they rest on the body not and do not stay in bushes or the like hang.

About such a rail devices that are provided with a mother rail or a mother profile, simply postponed. If the Ba Moving the mother profile are movable, the devices are also hooked from above, from the side or from below and tightened. In the latter case, the devices can engage in a transverse groove of the parent rail, whereby slipping along the parent rail is impossible.

On the underside of such, mounted under the barrel rail could at any time a block be put on, as he is for attaching the above Bipod is provided. It would have to the above explained Disadvantages to be accepted, such a salient, salient Block has. In addition, on a rail, on the front of a such block sits, no other device will be deferred.

aim The invention is the above-mentioned disadvantages of a rifle o. Like. counteract with a particular down attached parent rail, to simply attach or detach a device to a Rifle o. The like. To enable.

• – ein auf die Vaterschiene passendes Mutterstück umfaßt, das imstande ist, die Flanken der Vaterschiene zu hintergreifen, das Mutterstück an beliebiger Stelle der Vaterschiene aufsetzbar oder abnehmbar ist, und das an seiner Unterseite Gegenflächen zur Auflage der Auflageflächen aufweist,
• – eine Einrichtung zum Festlegen des Mutterstücks auf der Vaterschiene aufweist, und
• – einen vom Mutterstück nach unten abstehenden Block umfaßt, der zwischen den Gegenflächen angeordnet ist, um einen Zuganker einzuhaken.

This object is achieved according to the invention in a known adapter in that he

• A mother piece which fits on the parent rail and which is capable of engaging behind the flanks of the parent rail, the mother piece can be placed or removed at any point on the parent rail, and has counter surfaces for supporting the bearing surfaces on its underside,
• - Has a device for fixing the nut piece on the parent rail, and
• - Includes a protruding from the nut piece down block, which is arranged between the mating surfaces to hook a tie rod.

According to the invention Block not attached to the parent rail, but to a mother piece. The nut piece not only after solving the Device for his fixing of the paternal rail easily be removed, but also be moved at will, if, for example, another mounting location is desirable or unavoidable is.

Now could One thinks that the attached mother piece with the block is all the more would be a hindrance if the device or bipod is removed (if the following from the bipod Speech is not just a Harris bipod, but any one as well Device with same attachment arrangement meant). However, that remains Bipod firmly attached to the block; at least the fingers will be, if the bipod knurled screw solved must become, not moved apart or pushed apart, so the bipod always remains at the block. The situation where the separate block is off the parent piece while the mother piece mounted on the rifle does not occur when used correctly, because with removal of the bipod from the rifle always the mother piece is removed with. The disturbing, protruding block, which is the biggest drawback of the Harris bipod, does not appear in the present invention.

Should the bipod is used on a weapon that does not have weave or Picatinny rail or the like (father rail) the free ends of the fingers of the bipod with the knurled screw loosened pressed together and the motherpiece removed with block. But this is done only after the decrease of the whole Arrangement of bipod and mother piece of the parent rail. A shooter who acquired a rifle with father rail or a father rail at one Rifle so can not only continue to use his Harris bipod, but he can still do this on his previous rifles do not use the paternal splint, but only a protruding one Block.

It is possible, for example with a particularly narrow forend, between nut piece and bearing surfaces of the bipod to insert an intermediate piece, that the counter surfaces wearing. However, it is preferred that the underside of the nut piece the Size and shape a section, preferably the front end of the fore-end or hand protection of a rifle or the like. The counter surfaces are thus formed directly on the underside of the nut piece. As a Weaver or Picatinny rail relatively wide is, that must nut piece not overly widened become. If the mother piece made of metal, such as an aluminum alloy, or of hard plastic it is also possible the mating surfaces make narrower than the bearing surfaces of the bipod. The result reached, high surface pressure is for a mother piece made of metal or hard plastic harmless. The length of the Mother piece, longitudinal of the rifle, however, should at least the preferred support surfaces correspond.

It would be possible in the mating surfaces transverse grooves or slots for weight reduction contribute. Preferred according to the invention, is each of the mating surfaces however, in one piece coherently educated. Because namely the bearing surfaces with an elastomeric pad, these would be on the edges of Slits pressed in and when shooting damaged in the long run become. However, it has been found that the continuous longitudinal edges of the mother piece, if it is surmounted laterally from the bearing surfaces, because of their lower Load no damage cause the elastomeric pad of the bipod.

If the mother piece one piece is formed, then it is, such as a conventional rifle scope, on the Rail (mostly) pushed from the front. If front on the rail about a headlight or a laser rangefinder sits, then he has to be removed first. This is followed by the bipod with adapter deferred and finally again the headlight or laser rangefinder attached. This is a bit awkward. To these circumstances to avoid is according to another preferred embodiment The invention proposes that the nut piece has two parts, the around a longitudinal, Central pivot axis are pivotable, so they swing up embrace the side edges of the parent rail firmly and so the device to set the adapter to the parent rail. Here is thus first the one-piece mother piece changed into a two-part what Although a certain effort means. It turns, however out that way not just the adapter and thus the bipod can put on and take off the parent rail at any point across this but that thereby the locking device through the two parts is replaced. In addition, the locking device by the bipod served. If indeed the thumbscrew of the bipod is put on after putting it on, press each of the support surfaces the corresponding counter surface after above, where she embraces the flank of the paternal rail and joined this clamped against the other part. When removing the two swing Parts apart when the knurled nut the bipod dissolved again becomes. The adapter remains on the bipod, as long as not the Both free ends of the fingers are pressed together in a dissolved state.

To the Placing and removing the bipod are thus the same and only the same handles required as without adapters, but it is no fixed block required as it is without adapter Case would be. Rather, the bipod with its adapter can fit on any one Paternal rail and put on any place where space is. After removing the adapter, the weapon is not changed, so there is no protruding, obstructing block, as before without adapter was the case.

there may according to the invention preferably a further training consist in that at least on the top one of the pivotable parts a projection or a rib for engagement is formed in a transverse groove of the parent rail. This embodiment is preferably applicable only where the rail has transverse grooves. It will be, for example when pulling the weapon, so if forces parallel be applied to the axis of the adapter, the surfaces of the Adapters, which laterally surround the paternal rail and the adapter clamp there, not loaded. Rather, the load gets through the rib transferred directly to the father rail.

It would be possible, the Block in one piece with the mother piece train, at least then, then this one piece is. According to one However, further embodiment of the invention, it is particularly advantageous that the block consists of metal, preferably of steel, and of the underside of the adapter protrudes. The mother piece or its parts can be out Light metal alloy or plastic. As long as the anchorage the block is reliably solved in this light metal or plastic, is such a particularly stable, but (because of the possibility of pressure or injection molding) also particularly cost-effective solution achieved. It is immaterial how high the surface pressures when hooking the pins the fingers of the bipod become, because if for the Block a suitable metal chosen is, are these surface pressures still far below the load limit of the material of the block.

For the two-part nut piece Preferably, a further embodiment is proposed, the therein is that the block at its top a Längsmuffe has, which is penetrated by the pivot axis. The pivot axis, which can be produced inexpensively from any metal as a simple turned part is, supports over a large area the two parts of the mother piece from. The pivot axis passes through the sleeve, allowing a safe support is found. Besides that is for it Carried that block to take a position to each of the two nut pieces with appropriate design can, that's half corresponds to the angle that take both mother pieces to each other.

Around to simplify the removal of the bipod with adapter is preferred that the two parts of the adapter from a spring into a position depressed in which they release the father rail. Also the touchdown the adapter is simplified because the spring ensures that both parts of the mother piece be spread apart if they are not compressed by the support surfaces. So is also a touch upside down possible, So a touchdown from above on the turned up rifle.

there it is particularly advantageous that the spring as a wire spring is formed, which is wound around the pivot axis and from the top with each of its legs on one of the parts of the adapter suppressed. The spring is thus a simple, particularly inexpensive Wire-bending part.

The adapter consists in a favorable training only from a total of five parts, of which only the block is a little more expensive to produce, such as precision casting. The other parts are simple die casting or bending parts for the parts of the nut piece, a simple machine-rotating part for the pivot axis and a bending part for the spring. Optionally, a spring ring for holding the pivot axis is still required. By far the most expensive of these parts, namely the block, was previously required. For this small, additional effort according to the invention but not only the attachment of the unmodified bipod is made possible on a paternal rail, but also the attachment at any point, without leaving a trace after acceptance.

It is further preferred that the block on the longitudinal sleeve an upstanding Has nose for the engagement in a transverse groove of the parent rail is determined. These Nose becomes when putting adapter and bipod on the paternal rail inserted in a transverse groove of the paternal rail and sinking when donning the thumbscrew slight down, but not so far that it gets out of the cross groove. Thus, the nose is in the same way the seat of the two parts of the Mother rail in the weft direction sure as well as the one mentioned above Head or rib, which is why the nose can be omitted.

Of the The invention will be explained in more detail in an embodiment, which in the drawing is shown, but in no way the invention restrict should. In the drawing shows:

1 a hand guard of a rapid-fire rifle in side view, with the attached adapter, the bipod is omitted for the sake of clarity,

2 the longitudinal section (section AA in 3 ) by the picture of the 1 .

3 the front view of the handguard of the 1 .

4 the cross section (section BB in 2 ) by hand protection and adapter, wherein the bipod is indicated, and

5 a plan view of the removed adapter in the oblique view.

In 1 to 4 is a one-piece hand protection 5 made of aluminum, which is pushed from the front over the barrel and the gas removal of a rapid-fire rifle. On the barrel is not sitting, as usual, a grain carrier, but the sight is on the hand guard 5 on a Picatinny rail 7 , Four Picatinny rails 7 are on the handguard 5 arranged, namely an upper, a lower and two lateral. An arrow C denotes in 1 and 2 the direction forward, ie in the weft direction.

On the lower Picatinny rail 7 is an adapter that comes with a total of 1 is labeled, clamped with Harris bipod. This Harris bipod is well known and therefore not shown for the sake of simplicity; only the upper part of the part 4 that the bearing surfaces 11 is in 4 shown in cross section.

The adapter 1 consists of two swivel parts 2 . 3 around a pivot axis 13 can swing. For this purpose, the swivel part 2 three laterally projecting hinge extensions 15 on, in the three lateral hinge extensions 17 of the swivel part 3 intervention. It is between the middle hinge extensions 15 of the swivel part 2 a recess 19 leave in the a sleeve 21 engages the top of a block 23 is integrally formed. Through the hinge extensions 15 . 17 and through the sleeve 21 runs a through hole 25 in which the axis 13 sitting with a light play.

The part of the hole 25 that through the sleeve 21 runs, may be slightly smaller than the hole 25 through the extensions 15 . 17 so that the sleeve 21 and thus the integrally connected block 23 with press fit on the axle 13 to sit. This allows an axle head on one side and a spring washer on the other end of the axle 13 unnecessary.

The block 23 protrudes down between the two pivoting parts 2 . 3 out, is approximately square in cross-section and has a transverse bore 27 , It is thus identical to the known mounting block for Harris two legs, but differs from this in that it instead of the known mounting device on the top of the sleeve 21 having. This sleeve 21 guaranteed in cooperation with the other parts of the adapter 1 that the transverse bore 27 of the block 23 always pointing transversely to the weft direction.

A nose 31 on the top of the block 23 and thus the sleeve 21 is formed, projects into a transverse groove 33 the Picatinny rail 7 (generally referred to as "father-rail" in the foregoing description). The nose 31 prevents loosening of the adapter 1 forward or backward, on the paternal rail 7 based.

In 5 a variant is shown in which between two hinge extensions 17 of the swivel part 3 a recess is left, and a helical spring 29 on the axis 13 is deferred. The two ends of the spring 29 are formed as legs projecting radially to opposite sides. The legs are in corresponding notches of the pivoting parts 2 . 3 on, so that the pivoting parts 2 . 3 be swung apart in one direction by the rail 7 points away.

When setting up the Harris bipod first the knurled screw is loosened and the pins are at the upper end of the fingers of the bipod (not shown in the drawing) from both sides in the transverse bore 27 hooked. Then the pivoting parts 2 . 3 swung apart, as long as this is not the case in the execution of the 5 shown and explained helical spring 29 happens. Then the adapter 1 with the bipod on the rail from below 7 set, with the upper, lateral flanks of the adapter 1 or the pivoting parts 2 . 3 straight from the bottom up over the side edges of the rail 7 let slide. Then the knurled screw of the Harris bipod is tightened, causing the block 23 a little down between the upper parts 4 The Harris rail is pulled so that the bearing surfaces 11 from below each on a counter surface 35 of the swivel part 2 . 3 seated. Here are the pivoting parts 2 . 3 so swung with its edge upwards that they are the respective side flank of the parent rail 7 overlap and attach firmly to this side flank. Elastomer pads on the bearing surfaces 11 can even improve the firm connection, as they compensate for fine misalignment.

When removing the harris leg, its knurled screw is loosened. Then swing the two pivoting parts 2 . 3 diverge or become affected by the action of gravity ( 5 ) by the helical spring 29 pushed apart, leaving the rail, father rail or picatinny rail 7 is released and the bipod can be easily removed down. The pins at the ends of the fingers remain engaged with the transverse bore 27 so that bipod and adapter 1 always stay together.

Removing and attaching the bipod with adapter 1 is thus much easier than it is without an adapter 1 the case would be.

Only when you have the adapter 1 If you want to lose weight, for example, if the bipod is to be used on another rifle with conventional support and no patina, you simply squeeze the lower ends of the fingers together with the bipod dissolved. Then you can get the adapter 1 lift out to the top. This is the same action as removing the bipod from a conventional mount rifle.

The adapter 1 thus does not limit the use of the bipod in any way, but extends it. In addition, a rifle with parent rail, which remains the adapter 1 needed, undamaged, even if the bipod is attached, while in the conventional holder is to install a block that affects the rifle not only in appearance, but by that it protrudes from the rifle. Its uses without bipod are significantly affected.

In the embodiment of the hand guard 5 with father rails 7 and the two pivoting parts 2 . 3 made of aluminum alloy while the pivot axis 13 made of steel. The block 23 with sleeve 21 can be made of aluminum or steel. But there are also all sorts of other materials possible, as far as they are up to the stresses, in particular hard plastic for the pivoting parts 2 . 3 ,
