Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sight and method for a weapon, and more particularly to a sight and method for a rifle or other sighted weapon.

A sighted weapon, until it zeros, i.e.
A weapon cannot be used effectively until it is aimed properly so that when it is fired, it hits a properly aimed target. Thus, a zeroed weapon can compensate for many factors that affect drop of shot. In general, a good marksman will manipulate his weapon in a particular way (but repeatable) in terms of behavior when firing a round of bullets. The archer's behavior causes the aiming deviation to be aimed at a position that will result in a hit on the target when the shooter's behavior is taken into account, rather than at a position where the weapon is aimed directly at the target. In order to ensure that the desired aiming deviation is given accurately and repeatedly,
It must be possible to adjust the sight of the weapon to a position that provides the desired aiming deviation when the target is sighted.

Conventionally, zeroing a weapon is performed by aiming the weapon at a target within a certain range and firing sporadically. At this time, the shooting drop at the target position was confirmed,
The aim is adjusted and readjusted until the weapon aimed at the target accurately hits the target.

Although the above method allows correct zeroing of the weapon, there are a number of problems. For example, a certain range and sporadic live ammunition are required. Since live ammunition is a valuable resource and is used for exercises and actual battles, the above method is inconvenient, costly, and wasteful. Weapon zeroing must be done every time the field of view changes (for example, when daylight field changes to night field) and is a regular practice in these operational situations. Once the battle has started and you are unable to get within range,
It is not possible to change the viewing zone or perform zero point adjustment.

Another drawback is that once a weapon is zeroed by a particular shooter, it cannot be used by another shooter until a new zeroing is performed.

According to one feature of the invention, a graticule is placed at a known visible position with respect to the weapon in front of the weapon's field of view, and the graticule is sighted with respect to the field of view to zero the weapon. A method for aiming a sighted weapon is provided, which is characterized by adjusting the field of view to a predetermined position.

Preferably, the predetermined position is for aiming the graticule with respect to the viewing zone, adjusting the viewing zone to a reference position of the graticule where the viewing zone is aimed at the weapon, and independently zeroing the weapon. , established by reaiming the graticule.

According to another feature of the invention, means are provided for placing the graticule in a known visible position with respect to the weapon, in front of the sight field of the weapon, so that the graticule can be aimed with respect to the sight field. Provided is a sighting device for a sight-type weapon, which is characterized in that the viewing area can be adjusted to a predetermined position for zeroing the weapon.

In this case, it is preferable to provide the graticule with a reference mark for aiming the sight into the weapon. It is also expedient to form the graticule as a lattice structure arranged symmetrically around this fiducial mark. In a preferred construction, the grating structure is constructed as coarse grating sections with identification symbols, within which fine grating sections are provided for more precise analysis. More preferably, the coarse grid portions are sufficiently finely defined that they are visible to the naked eye using an iron sight and the fine grid portions are visible using a telescopic or other magnifying sight.

Advantageously, the image of the graticule is arranged to be visibly projected and calibrated in such a way that the accuracy is independent of the fore-aft position of the graticule relative to the weapon.

Preferably, the position of the graticule is set by means cooperating with the barrel of the weapon, said means being formed as a spigot rod or insert having an outer diameter equal to the inner diameter of the weapon to be aimed. . It also includes clamping means for clamping the graticule at a known height with respect to the insert, said clamping means being configured in the form of an extension arm. The extension arm is adapted to extend vertically downwardly from the position of the graticule in use and is provided with a precisely positioned groove for engagement with the bayonet member to position the graticule in the known viewing direction. It can be clamped precisely in position. A further feature is that this extension arm is formed with a number of grooves, which allow the guide to be placed in a suitable position for zeroing different types of weapons. The insert is also held by an extension arm so that it can be slid from one groove to another before being clamped into position in the groove appropriate for the weapon to be zeroed.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

There is a projector 10 (FIG. 1) as part of the sight, and the projector 10 is for projecting a graticule 11 that can be seen from a viewpoint position 12. A graticule pattern (not shown) is formed on the surface 14 of the graticule 11 by, for example, printing on glass.

The graticule 11 is illuminated from the outside by ambient light incident on the frosted glass plate 15, and can be seen from the viewpoint position 12 as described above. The light rays from the graticule 11 are refracted in parallel by one lens pair 16 having a focal point at the position of the graticule pattern so that the image of the graticule is formed at infinity. The projector 10 has a body 17, which is preferably formed into a substantially cylindrical shape.

The graticule 11 is attached to the body 17 by adhesive, for example.
It is attached to a flanged support member 18 that is movable within the flange. During assembly, the position of the support member 18 is first fixed horizontally in front and behind the holding member 19.100,

02) in the vertical plane. These set screws are adjusted so that the reference position of the graticule image appears exactly on the centerline 103 and is then fixed in place. When this adjustment is completed, the camp 104 closes the assembly (cap 104
It also has the function of holding the frosted glass plate 15). The structure is sealed from the outside world by two O-ring seals 105,106.

A weapon sight 20 (FIG. 2) according to the invention comprises a projector 21 of the type described above. Projector 21
is for providing a reference image of the graticunil that can be seen from the viewpoint position 22. The position of this fiducial image relative to the weapon is determined by the extension arm 23. The extension arm 23 is attached to the projector 21 and is configured to extend vertically from the projector 21 in use. Also clamped to the extension arm 23 is a spigot or insert 24 adapted to extend into the barrel 25 of the weapon. The graticule 26 projected by the projector 21 is fixed in a known position by clamping the insert member 24 with the extension arm 23. The extension arm is provided with a groove 27 (for the insert 24 and therefore for the weapon barrel 25).
The extension arm 23 can be positioned accurately. The clamp 28 of the insert 24 is in the form of a yoke and carries an end stop 29 and a clamping screw 200 which serves as a grip for the insert 24.

The groove 201 is arranged so that the centerline 202 of the projector 21 is at a height h at a known position above the barrel 25 of the weapon (this height h is the height h at which the reference mark 203 at the boresight of the weapon is located). It serves to accurately position the height of the graticule 26 relative to the weapon so that it is located at the same height as the weapon. By providing a plurality of grooves along the extension arm 23, accurate positioning at a plurality of heights is possible. These heights are determined appropriately so that the reference mark 203 can be positioned at the boresight of a plurality of different types of weapons. The clamp 28 is inserted into the valley groove by engaging a spring-biased ball stop (not shown) with a guide groove formed on the side edge of the extension arm 23 like the guide groove 204 of 'a27. Can be easily positioned in adjacent locations. This allows a single extension arm to zero a number of different types of weapons.

In order to further increase the number of applicable weapon types, inserts with different diameters can be co-operated with barrels with bores of various diameters. Further, in order to facilitate use at night, the end cap 205 of the projector 21 may have a built-in light source, such as a β-ray torch. Accordingly, a typical kit capable of zeroing in accordance with the present invention includes a projector and extension arm assembly.
It may consist of a plug-in member with various bores and a light source for night use. Such kits are inherently versatile, so even if a group of shooters are carrying various types of weapons, each individual shooter does not need to carry a separate sight. , 1 group of archers is 1
It is sufficient to carry one kit with you.

Projected pattern 30 of graticules (Figure 3)
has a coarse lattice portion 31 formed as a square lattice and a fine lattice portion formed as a plurality of crosses such as a cross 32, with one cross in each square of the coarse lattice portion 31. It is formed. The square consisting of the coarse grid portion 31 is A-F in the east-west direction and 1 to 1 in the north-south direction.
6, the pattern 30 further comprises a centrally located marker 33. The sizes of the projected pattern 30 are A to F and 1 to 6.
etc., the coarse grid portion 31 and fiducial marker 33 are visible to the naked eye and are intended for use with iron sights, whereas the fine grid portions are visible with telescopic sights or other magnifying sights. It is large enough to be visible.

For example, each square formed by a coarse grid section extends by an angle of 1 milliradian, and each square formed by a cross extends by an angle of 172 milliradians. This allows 100 m at a typical range of 100 m.
Resolutions of iu+ and 50 mm can be obtained, which is applicable to iron sights and 4x telephoto sights.

In order to clarify the features and advantages of the weapon sight according to the invention, its operation will be explained in detail below.

Before zeroing a weapon using the apparatus of the present invention, corrections required by the particular shooter for the type of weapon involved must be made.

For this reason, the shooter does the following:

First, the zero point adjustment device, that is, the clamp 28 of the sight 20
into a position adjacent to the groove appropriate for the type of weapon involved until the pole stop is engaged. Next, select the insert member 24 that matches the bore of the weapon, and
8 to the position of the groove 201 and the body part 25 of the weapon.
The zero point adjustment device 20 is supported by being placed inside.

When the extension arm 23 is vertically aligned, the projector 21 and thus the graticule fiducial mark 203 are precisely positioned a distance H above the barrel 25 of the weapon. The zeroing system of the present invention is insensitive to small errors in vertical alignment, and therefore vertical alignment can be satisfactorily maintained with a simple lip (not shown). The clip attaches to the body part 2 of the weapon.
It is preferable to attach it to the fire shroud 26 rather than to the fire shroud 5. In any case, clamping on the barrel must be avoided, which would impose undesirable loads and cause twisting.

The spigot or bayonet 24 ensures that the projection of the graticule is parallel to the axis of the weapon's body, and the height h is such that the height h of the graticule is within the field of view of the weapon's sight (not shown). chosen to ensure that the projection can be seen. The shooter then aims the weapon by aiming at the reference mark 203.

The sight is then removed from the weapon and, for example, fired at a target within range, by any conventional method known in the art, taking into account the drop in the shot and adjusting and re-adjusting the sight, until the bullet hits where it was aimed. Zero-calibrate the weapon.

For the next zero point adjustment, return the zero point adjustment device to the weapon and look at the projected graticule. Generally, the viewing zone is at a distance from a reference mark that defines a predetermined position for zeroing the weapon. This position can be identified by means of a grid. The reference of the iron sight is represented by a coarse grid section 31, for example at the upper cloth corner at the "A6" position. The reference of the magnifying sight is resolved by a fine grid section 32, and at the position "rA6 upper left" there is a reference at the Shonin corner. By remembering this criterion, the shooter can zero all weapons of the same type using only the zeroing device.

To accomplish this, the zeroing device is inserted into the as-yet unzeroed weapon in the manner described above, and the graticule is placed in a known position relative to the weapon. The graticule is sighted and adjusted into position by remembering the reference established above. This made it possible to quickly and secretly zero the M vehicle without firing live bullets. It also avoids the need for a certain range.

Considering the above-mentioned keys for zeroing, the only component that is susceptible to danger in the operating state is the spigot or insert.

If the insert member is even slightly bent, the zero point adjustment operation will become invalid. When performing a device check, the device is attached to the weapon, aiming the graticule and monitoring the aiming position. The clamp is then loosened and the insert is rotated slightly (eg, 172 turns). Even if you aim again, the aiming position will not change. If the aiming position changes, the insert is damaged and must be discarded.

The sight or zeroing device 20 is preferably made of a lightweight, strong material, such as aluminum. The weight of the device can be reduced by providing cutouts and perforations, such as cutouts 207 (FIG. 2). This allows the load acting on the barrel of the weapon to be minimized.

Since the device is used under a wide range of operating temperature conditions, thermal expansion may occur in the body of the projector 21, for example, and errors may occur. According to known optical techniques, one of the lens pairs 16 (FIG. 1) can be made of a material with temperature/index characteristics that can compensate for such errors.
