Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims priority under 35 U.S.C. .sctn.119
to German Patent Application No. 10 2006 009 893.5 filed Mar. 3,
2006, the entire contents of which are incorporated herein by
reference.
FIELD OF THE INVENTION
[0002] The invention concerns an adjustable sighting device for a
small arm, in particular a shotgun. The invention also concerns a
small arm with such a sighting device.
BACKGROUND OF THE INVENTION
[0003] In sporting shotgun shooting, especially in American Trap,
there are different sports disciplines that make different demands
on a gun with regard to point of impact and/or the target image.
Thus, for example, in American Single Trap the distance between the
pigeon bunker and the marksman's stand changes depending on the
degree of difficulty. In order to adapt to this change, the
marksman needs an adjustment possibility on his sight rail. Known
sighting devices of this type are limited, however, in their
adjustment possibilities, and usually permit only one-dimensional
adjustment.
[0004] The objective of the invention is to create an adjustable
sighting device of the type mentioned at the beginning, and a small
arm with such a sighting device, which have improved adjusting
possibilities.
SUMMARY OF THE INVENTION
[0005] This objective is attained by an adjustable sighting device
as set forth in the claims and by a small arm as also set forth in
the claims. Appropriate developments and advantageous refinements
of the invention are the subject of the dependent claims.
[0006] With the sighting device according to the invention, the
sight rail can be adjusted in height at both ends, relative to the
rail body, by adjustment elements. In this way, there is the
possibility of vertically adjusting the sight rail in the muzzle
area and in the rear area. Thus, both a parallel and an angular
adjustment of the sight rail can be obtained without producing
bending stresses in the sight rail. Another advantage of the
sighting device according to the invention is found in the
feasibility of simple replacement of the sight rail. It can be
simply mounted and if necessary, it can be quickly and simply
replaced. With the sighting device according to the invention, the
barrel is to a large extent free and can expand, relative to the
rail body, in the event of temperature fluctuations.
[0007] In a particularly appropriate embodiment, the sight rail can
be continuously adjusted relative to the rail body. This enables a
particularly accurate adjustment.
[0008] In an embodiment which can be simply operated, the
adjustment elements are formed by adjusting bolts that are arranged
in an articulated manner on the sight rail, and by corresponding
adjusting nuts on the rail body. The adjusting nuts are preferably
constructed as knurled nuts, and can thus be adjusted manually in a
simple manner.
[0009] In another appropriate embodiment, the sight rail is
situated on a middle element, which can be adjusted in height, such
that it can pivot. In this way, an additional support of the sight
rail relative to the rail body is obtained. In spite of the
additional guide, both a parallel and angular adjustment of the
sight rail can be obtained without warping.
[0010] Pressure spring are appropriately clamped in between the
rail body and the sight rail. The sight rail is thus held free from
play.
[0011] The rail body can be preferably guided on the barrel such
that it is movable, and is firmly connected to the barrel only at
one end. In this way the barrel can expand from heating without
producing warping or deformation of the rail body.
BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Other distinctive features and advantages of the invention
can be deduced from the following description of a preferred
embodiment example, with the aid of the drawing. The figures show
the following:
[0013] FIG. 1, a barrel of a shotgun with a sighting device
according to the invention, in a partially cut side view;
[0014] FIG. 2, a sight rail of the sighting device shown in FIG. 1
in a partially cut side view;
[0015] FIG. 3, a rail body of the sighting device shown in FIG. 1

[0017] FIG. 5, a cross-section along the line A-A of FIG. 4;
and
[0018] FIG. 6, the rear part of the barrel with the barrel hook
element in an enlarged, partially cut side view.
DETAILED DESCRIPTION OF THE INVENTION
[0019] FIG. 1 shows a barrel 1 of a shotgun with a hook element 2
and a sighting device with a rail body 3 fastened to the barrel 1,
and a sight rail 4 situated on the rail body so that it can be
adjusted.
[0020] The sight rail 4, shown separately in FIG. 2, extends almost
over the entire length of the barrel 1 and has adjusting bolts 6 on
its two ends, supported such that each can rotate around a
transverse pin 5, with a threaded shaft 7 projecting downwards. The
two adjusting bolts 6 are flattened laterally in the head area,
wherein a better guidance is obtained within the sight rail 4. A
sight 8 is fixed at the front end of the sight rail 4 on its upper
side. A middle element 9, protruding downwards, is supported in the
middle of the sight rail 4 such that it can rotate around a
transverse pin 10.
[0021] FIG. 3 shows the rail body 3, which can be mounted on the
barrel 1 to hold the sight rail 4. The rail body 3 extends over the
entire length of the barrel 1 and the hook element 2, and has
boreholes 11 at its front end and in the rear area to hold
adjusting bolts 6, and interconnecting transverse elongated holes
12 for adjusting nuts 13, shown in FIG. 1. Between boreholes 11 is
provided an opening 14, constructed here as an elongated through
hole, to hold the middle element 9 adapted to the shape of the
opening 14. The middle element 9 has the cross-section of a
round-ended feather key. On one side of the track is shown an
elongated hole 15 in the vicinity of a through hole for a
not-depicted counterscrew that meshes into a lateral threaded
borehole 16 of the middle element, shown in FIG. 1. Two pegs 17,
protruding upwards, with blind holes 18 to hold pressure springs
19, are provided on the upper side of the rail body 3 next to the
boreholes 11. On its underside, the rail body 3 has two stops 20
and 21, at a distance from one another and protruding downwards,
with T-shaped grooves 22 and 23. Here the stop 20 is located on the
front end of the rail body 3 and the other stop 21 in the area of
the middle opening 14. An end threaded borehole 24 for fastening
the rail body 3 to the hook element 2 is provided on the right rear
end of the rail body 3, shown in FIG. 3
[0022] As can be seen from FIG. 1, the two adjusting bolts 6 engage
with their respective threaded shafts 7 in the two adjusting nuts
13 located within the elongated holes 12. The two adjusting nuts 13
are constructed as knurled nuts and protrude laterally outside the
rail body 3. Radial threaded boreholes 25 with locking screws 26,
which can be seen in FIG. 6, are located in the adjusting nuts 13,
by means of which an undesired adjustment of the sight rail 4 can
be avoided. Furthermore, nondepicted cup springs are also located
on the underside of the adjusting nuts 13, which bias the adjusting
nuts 13 axially within the elongated holes 12. FIG. 6 also shows
one of the pressure springs 19, located in the blind holes 18 of
the two pegs 17, by means of which the sight rail 4 is biased
upwards relative to the rail body 3, and in this way is held free
from play.
[0023] For adjustment of the sight rail 4, it is possible to first
loosen the counterscrew located in the threaded borehole 16 so that
the position of the sight rail 4 can be changed relative to the
rail body 3. By rotating the two adjusting nuts 13, the sight rail
4 can be adjusted vertically in the muzzle area or in the area of
the hook element 2, wherein both a continuous parallel and an
angular adjustment can be attained without thereby producing
bending stresses within the sight rail 4. Markings or scales 27 for
indicating the adjustment position are placed on the sight rail 4
and/or on the rail body 3. Front shaft covers 28, which can be seen
in FIG. 1, are fixed on the right and left side of the rail body
3.
[0024] For assembly of the sighting device, the barrel 1, shown in
detail in FIG. 4, has on its upper side two bases 29 and 30, at a
distance from one another, to hold the downwards-protruding stops
20 and 21 of the rail body 3. In this respect, the two bases 29 and
30 have a T-profile, which can be seen in FIG. 5, which fits the
T-shaped grooves 22 and 23 of the stops 20 and 21. In this way, the
rail body 3 can be shoved onto the barrel 1 from the front until
with its backside 31, and according to FIG. 6, it encounters an
upwards-protruding stop 32 of the hook element 2 and can be fixed
by means of a securing screw 33 on the hook element 2, screwed into
the threaded borehole 24. The two bases 29 and 30, for example, can
be welded onto the barrel 1 or fixed to it in some other way.
[0025] In the embodiment shown, the barrel 1 is constructed with
the barrel hook 2 as an alternate barrel for a receiver of an
over-and-under shotgun. Instead of the upper barrel, however, the
sighting device is provided here. The securing screw 33 for fixing
the rail body 3 on the hook element 2 is situated, according to
FIG. 6, at the height of the upper striking pin and has a middle
through hole 34 with a stop pin 36, which acts rearward by means of
a spring 35, for the nondepicted, upper striking pin of the
double-barrel shotgun. In this way, a striking pin damper is
created that cushions the upper striking pin when it strikes and
protects it.
