Description

Front sight device and rear sight disc for sport rifles, in particular Front sight device for a match rifle.

The present invention relates to a sighting device and a sight disc for sport rifles in particular ring front sight device for a Mateh rifle, the muzzle side Is arranged above the barrel and provided with a grain jacket in which an adjustable Ring front sight arranged iet, front sight device # for sport rifles, in particular ring front sight devices for match shooting, there are known to be in different versions. In particular such grain devices are known in which a grain jacket over the mouth side the barrel of the wafer @ is mounted and serves as a holder for the grain. Preferably grain devices with exchangeable grain blades, especially ring grain blades, used for sight shooting, the diameter of which is generally 0.1 up to 0.2 mm. These front sight inserts generally have noob crossbars that on the one hand carry the front sight ring and on the other hand have the purpose of tilting or a different tilting of the weapon is obvious to the shooter when aiming do. Such steel leaf grain inserts are in production cheap and relatively easy to replace. In terms of shooting, however, it is a bar-less front sight to be preferred over a ring front sight with a support beam, as the shooter with a carrierless ring front sight inside and outside the ring front sight an unhindered one Blickfeld aui has the goal. In addition, the eye is spared and enables faster acquisition of the target. Such a beamless ring front sight device became known through the German utility model 1 947 432, in which the Ring grain in Porn of a ring engraved in a glass disk and then the ring is lined with an opaque material.

However, such an annular front sight device has a fixed eye hole size the disadvantage that with changing light conditions, with different mirror sizes targets, with eye strain, at different distances or with changing shooters, the front sight with the most suitable hole size is used would have to be selected and replaced accordingly in order to achieve a optimal shooting result reach su. In practice, however, changing the door inserts is too cumbersome, ao that the shooter prefers to forego the ultimate perfection of the aiming device.

By the German Auslegeschrift 1 302 789 as well as the German utility models G 69 49 429 and E 16 545 were also devices with adjustable front sights known, by means of which the most suitable viewing hole diameter can be found quickly and effortlessly when shooting can be adjusted. These known devices with visible hole diameters that can be produced however, invariably have the disadvantage that they are equipped with support beams are. The disadvantage of the ring beads equipped with a support beam compared to a Device iit a Bar-shaped ring grain, however, has already been mentioned above made clear The present invention is therefore the task 2ugruade, create a front sight device with a barless, adjustable front sight This task is carried out in the case of a grain device of the type mentioned at the beginning Art according to the invention solved in that the holder aue at least two transparent There are parts between which a deformable grain ring can be clamped, through Such an arrangement can be easily adjusted to a beamless, adjustable Realize ring front sight device in which the eye hole size can be easily controlled a wall tion of the clamping pressure can be realized.

The transparent material of the holder can at least partially made of glass and / or plexiglass or some other transparent plastic. A flexible O-ring, a hose ring or a cord ring can be used as a front sight ring serve with a soft core. Fine adjustable grain device can be obtained in that the deformable grain ring in the holder on its outer The scope is kept essentially free of play and changes in the size of the eye hole is compressed by the holder in the axial direction.

To avoid twisting and shear stress on the grain ring, the grain ring is preferably arranged in the axial direction between two co-axially arranged, clamped from a transparent material screw, each have a thread with different thread pitches and have a face tooth shnung can be coupled with each other. The threads each know from one Coarse win There is a tendency, as the size of the eye hole can be adjusted given solely by the difference in the thread pitches of the two threads will.

The object on which the invention is based can be divided into the same Way to solve the fact that the ring grain, which through the made of a transparent material Existing bracket is held by a lamellar basket or known per se Forms collet-like ring core arrangement. Here, the ring grain arrangement expediently of at least one transparent ring surrounding the grain arrangement Ring held, and the collet-shaped ring grain arrangement can ao formed sein1 that they have a tension-free diaphragm head provided with oblique slots having.

The holder for the ring front sight arrangement can be made of planar as well as lens-shaped transparent elements, e.g. made of plexiglass rings, which may be provided with impact-resistant edges or even inserts from Can be fuel part combinations. The mounting elements can be stationary, as well as axially displaceable and rotatable. It is also possible, in a manner known per se, the light transmission through täntes pane material after To reduce the need. It can also be useful on the axis of the shaft To provide a disc or lens that extends over the surface of the aperture, which can optionally consist of a colored, transparent material. Further can be used to adjust the size of the eyelet of the ring front sight, rotatably mounted sleeve a marking indicating the eye hole size and attached a peephole can be provided in the grain jacket, in which di. set sight size is readable. The den Individual eye hole sizes corresponding to positions are preferably marked with index grids.

In the event that the shooter from rear sight target shooting to rear sight / Ba @@ n, Want to transfer pearl or roof grain pouring, or vice versa, the arrangement can be taken as a precaution so that the barless Ringkorneinsats against effortlessly a grain sleeve or the like, which can be exchanged with any is equipped with a different grain shape. Such a sleeve also advantageously carries dimensions or reference numbers, e.g. the indication of the front sight width, which is preferably also is visible through the peephole in the grain jacket.

Around the shots when shooting, a tilting of the wax is obvious To do so, reinforcing ribs are expediently placed on the side of the grain device attached, which run parallel to each other and the grain jacket with the grain holder barrel Connect so that the reinforcement ribs in the correct shooting position of the Run rifle vertically.

In the event, however, that a shot does not hit an orientation bar the conventional way, so can before @@@ weise in the Ringk @@ nhalt @@ ng a notch running right across the cheek in the way that it is through the German usage @@ u @ ter 1 914 013 has become known.

In the following, the invention will be described in more detail with reference to in the drawing illustrated exemplary embodiments are explained. In the drawing demonstrate: Fig. 1 is a vertical longitudinal section with partial view of a Coning device, which is equipped with a flexible ring as a coning, Fig. 2 a vertical partial longitudinal section through a gate device, which is equipped with a visual hole tooth and pliers sleeve is equipped, Fig. 3 is a vertical longitudinal section through a Grain device and the muzzle, the grain device with a sleeveless eye hole pliers, Fig. 4 is a vertical longitudinal section by a tornsorrich ring, corresponding to FIG. 1, with the grain device, however is equipped with a bar grain sleeve, Fig. 5 a grain device, accordingly Fig. 3, seen in the SchuB-direction, Fig. 6 a grain device in accordance with Fig. 2, seen in the direction of the axis of the run, at the junction, and FIG. 7 shows a grain device, corresponding to Fig '6, which is, however, equipped with a beam front sight.

In Fig. T is an embodiment of one designed according to the invention Grain device shown in which the holder 1 of the grain device, from the Grain holder barrel 1a, the grain saddle 1b, the grain casing 1c and the ribs 1d, Muzzle side pushed onto the barrel 2 of a rifle not shown in detail ... d secured by means of a pin 3 is.

The grain jacket is each over part of its length with eei different Internal threads 25 and 26 provided, which have a different inner diameter -an4 have a different thread pitch. In the first internal thread 25 is a first inner screw 5 and in the second internal thread 26 is an adjusting screw 6 screwable. Both the screw 5 and the adjusting screw 6 are off an optically transparent material such as glass or plexiglass. The adjusting screw 6 eist a circular recess 27 into which a deformable Ring 4 is inserted so that there is preferably no play on its outer circumference has, and lies in the transverse direction to the longitudinal axis of the barrel 2. The ring 4 can consist of an O-ring or a hose ring or a cord ring, the inner Screw 5 has a stamp-shaped side on its side facing the adjusting screw 6 Approach 28, which preferably has the same cross section as the circular recess 27 and protrudes into this recess. The two screws 5 and 6 are on their mutually facing sides by a driver toothing 5a or 6a coupled. The different thread pitches of the internal thread 25 and the Internal thread 26 are preferably chosen so that the internal thread 26 has a larger Has thread pitch.

The front sight insert is actuated by first pressing the inner screw 5 and then the adjusting screw 6 with the ring arranged in the recess 27 4 is screwed in.

As soon as the drive screw 6 rotates, the drive teeth 5a and 6a come into mutual engagement, the two screws twist 5 and 6 together.

Due to the different thread pitches of the internal threads 25 and 26 guide the two screws in the same Drchung however an axial relative movement against each other. Such a training is It is possible to equip the glass bodies 5 and 6 with a material-related Orob thread and still achieve the effect of an integrated su or the press path large translate. At the same time, the advantage is still achieved that a uniform Drchung of the ring press surfaces is achieved, thereby ensuring that the ring 4 is not warped or crushed even if it is severely crushed.

Since the grain ring 4 already has no play on the outside in the uncompressed state is mounted in the recess 27, the rubber or the respective material escapes of the ring 4 depending on the degree of compression between the two screws 5 and 6 more or less inwards and thus creates a viewing hole 29, the size of which depends on the pressure exerted on the ring. The desired size of the ring aperture 29 can thus in a simple manner only by turning the adjusting screw 6 can be achieved. As the orientation and inertia bars, as they were with the previous known adjustable ring front sight designs were used in the invention Grain device to achieve a better unobstructed view are omitted the embodiments shown in FIGS. 1-7 lateral, long, parallels forming Ribs 1d are provided which connect the grain holder sleeve la and the grain jacket ic. The ribs id normally run when the rifle is in the correct shooting position is located vertically, so that the shooter when rotated this parallel Ripping against the vertical is shown in tilting the rifle when aiming. The ribs 1d also serve the purpose of reinforcing the holder 1 su and also a larger mating surface is created by the ribs for the locking pin 3.

In Fig. 2, a grain device is shown in which in the grain jacket 1c a glass ring 9 is held. The glass ring 9 sits in the bore le of the grain jacket and lies with its rear surface against a shoulder If, while it is also the opposite side is held by a bearing surface 10a, which is through the The end face of a threaded sleeve 50 screwed into the torn jacket is formed. The glass ring 9 holds in the middle a per se known Sehlochsange 7, which is also in known manner in a pliers sleeve 8 by means of a. Screw thread 8a axially is arranged movably. As a result of the glass ring 9, the ring grain appears to be carrierless. If, however, an orientation line should be required in special cases, so an orientation notch 9a (Fig. 5) can be provided.

The eye pliers 7 has an obliquely slotted diaphragm head 7a, the purpose of which is to cover the pliers slots parallel to the axis. So on the pincer members cannot twist, the diaphragm head 7a protrudes over the collet clamping bead 8e out of the collet 8.

The screw slot 7c is used to adjust the pliers by a Rotation of the eye-piercing forceps 7 this is shifted against the forceps sleeve 8. At a Displacement of the Sehlochsange 7 to the left in Fig. 2 with respect to the forceps sleeve 8 the diaphragm head 7a is further compressed by the collet clamping bead 8c, so that the viewing hole 31 is reduced. In the event of a displacement of the eye piercing forceps 7 in the opposite direction, the eye hole is enlarged by widening of the diaphragm head 7a.

There is 7c on the eye forceps 7 on the side of the screw slot a mark on the circumference of the eye-piercing forceps in the form of a pointer 11 attached. When the screw slot 7c is rotated, this causes a widening or a narrowing of the eye 31 is caused, a change takes place at the same time the radial position of the pointer 11, through which approximately the size of the set Eye hole can be estimated or noted.

Referring to Figure 3, another embodiment is one in accordance with the invention formed ring grain device shown, which also with a Sehlochsange 12 is equipped.

In this embodiment, however, the eye-piercing forceps is by a Glass pane 13 stored stationary while the widening and narrowing of the pliers head f2a takes place by an axial displacement of a pane of glass 14. The glass pane 13, which can also be thickened like a sleeve, is secured by a screw ring 16, which is screwed into a screw ring 15, taken. The screw ring 15 itself is provided over part of its length with an external thread 32 with which he screwed into a corresponding internal thread of the grain jacket 1c up to a stop 33 below is.

In a similar way, it is designed in the shape of a disk, ring or sleeve Glass body 14 taken in a threaded sleeve 17, which on one part of its length Has external thread 34 with which it is in a corresponding internal thread of an adjusting sleeve 18 is screwed, which is rotatably mounted in the grain jacket 1c. In the threaded sleeve 17, a slot 35 running in the axial direction is formed into which a slot 35 in the screw 19 protrudes from the Korniantel.

In this way, the threaded sleeve 17 is against radial rotation secured, so that when the adjusting sleeve 18 is rotated, it is only an axial one Can perform shift. When the adjusting sleeve 18 is rotated the glass sheet 14 held by the threaded sleeve 17 will, shifted in the axial direction, with the pliers head 12a either accordingly compresses or releases it accordingly, so that a Verongung or an expansion of the eye hole can be brought about The eye hole pliers 12, the glass pane 15 and the screw ring 15 can together also represent a one-piece injection-molded part combination. The same also applies to the glass body 14 and the threaded sleeve 17.

The mouth-side end of the eye-piercing forceps 12 has an external thread provided on which a threaded ring 20 is screwed through which a disc or Lens 21 is held against the end of the eye piercing forceps 12 The disc 21 is covered the whole eye hole and it can in particular be made of a tinted glass so that the eye hole stands out from the ring outside the front sight ring. For For special optical purposes, the disk 21 can also be replaced by a lens.

The adjusting sleeve 18 has index catches 18a on its circumference, in which engages a spring-loaded ball 18b. In this way certain Rotational positions of the adjustment sleeve that correspond to certain eye openings easy way tind way to be perverted. Furthermore are on the circumference of the adjustment sleeve 18 hole size numbers attached, which correspond to the I. index grid, so that the respective set eye hole size, about 4.0, in one in the grain jacket 1c trained inspection hole 1g appears.

The grain device shown in FIGS. 4 and 7 corresponds to in Fig. 2 and 5 shown ring grain device, but with a replaced one Ring insert. Thus, in the embodiment shown in FIG. 4, the one shown in FIG. 2 inclined glass ring 9 has been removed by unscrewing the threaded sleeve 10. Instead of the glass ring 9, the bar grain sleeve 22 is then in the grain jacket 1c been used. The beam grain sleeve 22 has a beam grain shape 22a, however the grain sleeve could also be made with a different grain shape, e.g. with a pearl, roof or stem-ring front sight.

On the bar grain sleeve 22 a nose 22b is provided, which in a The fitting groove 36 (see FIG. 2) is seated in the grain jacket 1c. This ensures that the grain adjusted in a certain position in relation to the grain jacket and in this Position is held. A number can be indicated on the outer circumference of the front sight sleeve Be provided over the 33 limestone grain width (3.0), which in the inserted state of the Bar grain sleeve can be read in the viewing hole 1g.

In the embodiment shown in Fig. 4 is between the 3alkenkornhülsc 22 and the screw ring 10 still a ge töate glass pane or glass lens 23 clamped, which is also intended for special optical purposes.
