Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a firearm, in particular to
a self-loading small-caliber rifle.
[0002] A firearm of the type mentioned above is comparatively
complex. In particular, a firearm such as this is frequently
suitable only for right-handed gunners. The firearm can only be
converted only by means of expensive additional parts to make it
suitable for left-handed gunners.
[0003] One problem on which the invention is based is to provide a
firearm of the type mentioned initially which can be converted at
low cost and/or easily for left-handed gunners and right-handed
gunners.
SUMMARY OF THE INVENTION
[0004] The firearm according to the invention may be in the form of
a rifle, in particular a small-caliber rifle. However, the firearm
may also be in the form of a handheld firearm, in particular a
pistol or revolver.
[0005] The invention provides for the breech and/or the breech
housing to be designed such that the firearm can be changed from a
first assembled arrangement, which is suitable for right-handed
gunners, to a second assembled arrangement, which is suitable for
left-handed gunners, with the firearm preferably being in the form
of a rifle of the Bullpup type. Particularly in the case of a rifle
of the Bullpup type, it has been found to be extremely important to
adapt the firearm for left-handed or right-handed gunners since,
otherwise, powder vapors or the like emerge close to the gunner's
head.
[0006] In this case, the invention makes it possible to provide the
capability for the assembled arrangement which is suitable for
right-handed gunners, to use essentially the same parts, in
particular, the identical parts, as those used for the assembled
arrangement which is suitable for left-handed gunners.
[0007] A firearm according to the invention provides the
capability, by means of the arrangement of the individual parts
with respect to one another, to assemble the firearm either such
that it is suitable for a right-handed gunner, or else to assemble
it such that it is suitable for a left-handed gunner. This avoids
additional costly parts for conversion.
[0008] The invention makes it possible to provide for the breech
and/or the breech housing to be essentially left/right symmetrical
in the installed position. The symmetrical configuration of the
breech housing allows the low-cost conversion mentioned above to be
achieved using the same parts and in a very simple means.
[0009] The invention in this case makes it possible to provide for
the breech housing to have cutouts both on its left-hand side in
the installed position and on its right-hand side in the installed
position, whose size and position correspond to one another on the
left-hand side and on the right-hand side.
[0010] The invention in this case makes it possible to provide for
panels as well as an injection window to be incorporated in the
cutouts.
[0011] The invention in this case makes it possible to provide for
a slide retraction lever to project through one of the cutouts both
on the right-hand side and on the left-hand side of the breech
housing, depending on the assembled arrangement.
[0012] The symmetrical arrangement of the cutouts on the left-hand
side and on the right-hand side of the breech housing thus makes it
possible to interchange the panels and injection windows in a very
simple manner, so that the firearm can be converted from the first
assembled arrangement to the second assembled arrangement in little
time and at low cost.
[0013] The invention makes it possible to provide breech to in each
case have a longitudinal slot and/or a circular opening on its
left-hand side and right-hand side in the installed position.
[0014] The invention makes it possible to provide for the size and
position of the longitudinal slot which is arranged on the
left-hand side to correspond to the size and position of the
longitudinal slot which is arranged on the right-hand side, and/or
for the size and position of the opening which is arranged on the
left-hand side to correspond to the size and position of the
opening which is arranged on the right-hand side.
[0015] The invention in this case makes it possible to provide for
an extractor and/or a slide retraction lever to be fitted both on
the left-hand side of the breech and on the right-hand side of the
breech.
[0016] The symmetrical design of the breech can thus be used to
change the firearm from the first assembled arrangement to the
second assembled arrangement using very simple means and at low
cost.
[0017] The invention makes it possible to provide for the breech to
be in the form of an MIM (metal injection molding) part, in
particular in the form of an MIM part composed substantially of
steel. The use of an MIM part for the breech considerably reduces
the production costs for the breech. Nevertheless, a breech can be
produced from steel powder for the production of this MIM part,
which has approximately the same density and approximately the same
characteristics as a breech which is machined from steel.
[0018] The invention makes it possible to provide for the breech
housing to be manufactured at least partially from a zinc
dye-casting.
[0019] The invention makes it possible to provide for the system
housing to be manufactured at least partially from a zinc
dye-casting.
[0020] The production of the breech housing and system housing from
a zinc dye-casting reduces the production costs for these parts,
with their functionality not being adversely affected, or being
adversely affected only insignificantly, by the choice of a zinc
dye-casting as the material. Furthermore, the use of zinc dye-cast
parts reduces the weight of the firearm.
[0021] The invention makes it possible to provide for the stock to
be manufactured at least partially from plastic. Manufacturing the
stock from plastic reduces the production costs of the firearm, and
reduces its weight.
[0022] The invention makes it possible to provide for the sear to
be at least partially in the form of an MIM part, in particular, an
MIM part which is composed substantially of steel. Manufacturing
the sear as an MIM part also considerably reduces the production
costs of the firearm.
[0023] The production of individual parts of the firearm as an MIM
part, zinc dye-cast part, or plastic part offers the advantage that
parts, such as these, can be removed ready for use from the
corresponding mold that is used to produce them. There is no need
for labor-intensive subsequent machining, thus making it possible
to considerably reduce the production costs.
[0024] The invention makes it possible to provide for the barrel to
be connected to the breech housing via an eccentric screw
connection. The eccentric screw connection allows a very firm
connection, involving very little complexity, to be produced
between the barrel and the breech housing, in particular because a
single screw makes it possible to provide two different contact
options.
[0025] The invention makes it possible to provide for the firearm
to have a stock upper part which can be connected to the breech
housing via a latching connection. The use of a latching connection
for connection of the stock upper part to the breech housing makes
it easier to disassemble and assemble the firearm.
[0026] The invention in this case makes it possible to provide for
the firearm to have a rear stock, which covers the latching
connection between the stock upper part and the breech housing when
the firearm is in the assembled state. The use of the rear stock to
cover the area of the latching connection between the stock upper
part and the breech housing results in the latching connection
providing similar safety to a screw connection as is known from the
prior art.
[0027] The invention makes it possible to provide for the rifle to
have a magazine safety device which can block the push rod.
Magazine safety devices are admittedly known from the art for
handheld firearms, but not for long-barreled weapons. The present
invention thus for the first time provides a magazine safety device
for a long-barreled weapon.
[0028] The invention makes it possible to provide for the push rod
to be connected to the trigger via a spring element, in particular
via an angled spring steel rod. The connection of the push rod to
the trigger via a spring element makes it possible to prevent
pressure on the trigger causing damage to the firearm when the push
rod is blocked by the magazine safety device, because the spring
element can absorb the forces that are applied.
[0029] The invention makes it possible to provide for the firearm
to have two breech springs which are parallel to one another. The
use of two breech springs instead of one large breech spring, as is
known from the art, makes it possible to further reduce the
production costs of the firearm.
[0030] The invention makes it possible to provide for the stop
damper to be manufactured from plastic. The use of plastic for the
stop damper on the one hand reduces the recoil mode, while on the
other hand it allows the costs for production of the firearm to be
reduced.
[0031] The invention makes it possible to provide for the stop
damper to have at least one holder for guiding the spring guide
rod. The stop damper can thus carry out two functions, specifically
on the one hand the function of damping and on the other hand the
function of guiding the spring guide rod. This makes it possible to
further reduce the costs of the firearm.
[0032] The invention makes it possible to provide for the firearm
to have two magazine holders. Despite the rifle being of the
Bullpup type, the abovementioned measure according to the invention
for the first time makes it possible to also accommodate a spare
magazine in a rifle such as this.
[0033] The invention makes it possible to provide for an unlocking
element for removal of a magazine to be arranged in the recess, in
particular on the rear face of the recess. Positioning of the
unlocking element on the rear face of the recess, which is used as
a thumbhole, has been found to be highly ergonomic.
[0034] The invention makes it possible to provide for the stock to
have a mounting rail, and for a sight part of the sight (48) to be
integrated in the mounting rail. Integration of the sight part in
the mounting rail makes the firearm more compact, and can
contribute to reducing the production costs of the firearm.
[0035] The invention makes it possible to provide for the sight
part to be moved from a stow position to an in-use position, in
particular by moving it upwards to the in-use position of the
firearm. The capability to stow the sight part makes it possible to
protect it against damage.
[0036] The invention makes it possible to provide for the sight to
have a disk which can rotate and has grooves which are used for
aiming in it, in which case different grooves can be used to select
different elevation positions for aiming. The disk which can rotate
and has the various grooves allows different elevation aiming
positions in a very simple manner.
[0037] The invention makes it possible to provide for the safety
unit to have at least one operating slide with a safety vane which
is arranged on it at the end and has a colored marking, with a
safety vane which has a colored marking being visible during the
aiming process, in particular from above, when the firearm is in
the armed state. The visibility of the safety vane with the colored
marking during the aiming process improves the handling safety of
the firearm according to the invention.
[0038] The invention makes it possible to provide for the firearm
to have a childproof safety device which acts on the safety unit.
In the prior art, childproof safety devices generally act on the
trigger itself. A childproof safety device which acts on the safety
unit reduces the complexity for production of a childproof safety
device such as this.
[0039] The invention makes it possible to provide for the firearm
to have a cocking indication. A cocking indication such as this
provides the gunner at all times with information as to whether or
not the firearm is cocked.
[0040] In this case, The invention makes it possible to provide for
the cocking indication to be in the form of a colored marking on
the rear face of the or of one of the panels, which can be inserted
into one or more of the cutouts in the breech housing. The
arrangement of the colored markings for the cocking indication on
the rear face of one of the panels represents a very simple way to
produce a capability to provide such a cocking indication.
[0041] The invention makes it possible to provide for the system
housing to have the capability to be connected to the rear stock by
means of at least one screw, which can be held on the rear stock by
means of a flexible plastic part. The abovementioned flexible
plastic part which, by way of example, can also be injection molded
during the manufacture of the rear stock from plastic allows the
screw to be held by very simple means.

DETAILED DESCRIPTION OF THE INVENTION
[0071] The firearm according to the invention, which is in the form
of a rifle, and of which an exploded illustration can be seen in
FIG. 1 and a perspective view can be seen in FIG. 28 essentially
has a barrel 1, a breech 2 with a breech housing 3, a trigger 4, a
system housing with system housing halves 5, 6, as well as a front
stock 7, a rear stock 8 and a stock upper part 9.
[0072] The detailed view of the rear section of the rifle
illustrated in FIG. 2 and FIG. 3 shows that a grip 10 is integrally
formed on the rear stock 8. Two cutouts 11, 12 are arranged on each
of the longitudinal faces of the breech housing 3. The size and
position of the cutouts 11, 12 on the left-hand side of the breech
housing 3 correspond exactly to the size and position of the
cutouts 11, 12 on the right-hand side of the breech housing 3.
[0073] In the assembled arrangement of the rifle according to the
invention as illustrated in FIG. 2, the cutouts 11, 12 which are
located on the left-hand side of the breech housing 3 are closed by
panels 13, 14. An ejection window 15 is incorporated in the front
cutout 11 in the firing direction on the right-hand side of the
breech housing, through which an extractor 16 which is located in
the interior of the breech housing can eject the empty cartridge
cases. The empty cartridge cases are thus ejected on the right-hand
rear side of the rifle, so that the rifle is suitable for a
right-handed gunner. An extractor 17 is also arranged in a
corresponding manner on the right-hand side of the breech 2. The
breech is likewise symmetrical for this arrangement of the
extractor 17 and for the arrangement of a slide retraction lever
18, such that the abovementioned parts can be used both on the
left-hand side and on the right-hand side of the breech 2. In this
context, reference should be made to FIG. 11, which shows a
longitudinal slot 19 on the breech 2 for holding the extractor 17,
and an opening 20 with a circular cross section for holding the
slide retraction lever 18. In this case, longitudinal slots 19 and
openings 20 whose sizes and positions in each case correspond
exactly to one another are located both on the left-hand side and
on the right-hand side of the breech 2.
[0074] As can be seen from FIG. 2, the slide retraction lever 18
extends to the right from the breech 2, so that it can extend to
the right out of the breech housing 3 through the rear cutout 12 in
the firing direction. The assembled arrangement shown in FIG. 2 is
thus suitable for right-handed gunners.
[0075] In the assembled arrangement for left-handed gunners shown
in FIG. 3, the panels 13, 14 are inserted into the cutouts 11, 12
on the right-hand side of the breech housing 3. The ejection window
15 is inserted in a corresponding manner into the front cutout 11
on the left-hand side of the breech housing 3. Furthermore, the
extractor 17 and the slide retraction lever 18 are mounted on the
left-hand side of the breech 2, so that the slide retraction lever
18, in particular, can extend out of the breech housing 3 through
the rear left-hand cutout 12. The assembled arrangement shown in
FIG. 3 is thus suitable for left-handed gunners.
[0076] FIG. 2 and FIG. 3 in particular show that the process of
conversion from an assembled arrangement for right-handed gunners
to an assembled arrangement for left-handed gunners can be carried
out without the use of additional parts. All that is necessary is
to move parts from the left-hand side to the right-hand side, and
parts from the right-hand side to the left-hand side.
[0077] FIG. 11 once again illustrates the breech 2, in more detail.
According to the invention, the breech 2 is in the form of an MIM
part (Metal Injection Molding). In this case, the breech is, in
particular, formed so as to allow the breech to be produced using
the MIM method. Further materials which are used are plastic for
the stock, that is to say for the front stock 7, the rear stock 8
and the stock upper part 9. The system housing and the breech
housing 3 are manufactured from a zinc dye-casting. It is also
possible for the sear 21 which can be seen in FIG. 1 to be produced
from steel using the MIM method.
[0078] FIG. 11 also shows that two spring guide rods 22 can be
attached to the breech 2, with two breech springs 23 being guided
on them. FIG. 11 as well as FIG. 12 and FIG. 13 also show a stop
damper 24, through which the spring guide rods 22 extend. The stop
damper 24 may be composed of plastic while, in contrast, the spring
guide rods 22 and the breech springs 23 may be composed of steel.
FIG. 12 shows the breech in a front position while, in contrast,
FIG. 13 shows the breech in a rear stop position, in which the
breech springs 23 are in the cocked state In the embodiment which
can be seen from FIG. 11 to FIG. 13 it is worth noting that the
stop damper 24 is at the same time used to guide the spring guide
rods 22. Two holes which extend through the stop damper 24 in the
longitudinal direction of the rifle are provided in the stop damper
24 for this purpose, in which case end stops 25 for the spring
guide rods 22 can also rest, in the assembled state, on that side
of the stop damper 24 which faces away from the breech.
[0079] FIG. 6 and FIG. 7 show the connection of the breech housing
3 to the stock upper part 9. The stock upper part 9 has four
latching tongues 26 which project downward and can be introduced
into corresponding latching holders 27 which are provided on both
sides of the breech housing 3. In this case, FIG. 8 shows that the
latching tongues 26 have a thickened area on their lower face,
which can engage in a groove (which is used as a latching holder
27) in the breech housing 3.
[0080] As can be seen from FIG. 2 and FIG. 3, in this case, the
breech housing 3 and the stock upper part 9 are introduced into the
rear stock 8 in the assembled state, in which they are clipped to
one another, with the connecting areas between the latching tongues
26 and the latching holders 27 being covered in a fitting form at
the side by the rear stock 8 when the stock is in the assembled
state, so that the connection between the breech housing 3 and the
stock upper part 9 cannot be detached in this assembled state.
[0081] FIG. 4 and FIG. 5 show the connection between the breech
housing 3 and the barrel 1. The connection is made via a holding
plate 28, which is fitted to the breech housing 3 by means of a
screw 29. The detailed view in FIG. 5 in this case shows that a
threaded hole 30 is provided in the breech housing 3, and is used
to hold the screw 29. Furthermore, a hole 31 is provided in the
holding plate 28, and is used to allow the screw 29 to be passed
through the holding plate 28. Furthermore, a cutout which extends
conically into the holding plate 28 is provided on the front face
of the holding plate 28, in order to accommodate the head 33 of the
screw 29. In this case, the rotationally symmetrical cutout 32 is,
in particular, not formed to be coaxial with respect to the
rotationally symmetrical hole 31 so that the holding plate is moved
both to the right as shown in FIG. 5 and upwards as shown in FIG. 5
by screwing the screw into the threaded hole 30 and thus by pushing
the conical head 33 of the screw 29 into the cutout 32. This allows
the holding plate 28 to fix the barrel 1 on the breech housing 3
both in the longitudinal direction of the rifle and in the vertical
direction. Once the screw 29 has been screwed in, it is
mechanically protected against sliding out. For this purpose, a
bracket-like screw securing device is pushed from the side through
a slot over the thread of the screw 29, for example in the end area
of the arrow, which is provided with the reference symbol 30.
[0082] As can be seen from FIG. 14, the trigger 4 is connected to
the push rod 35 via a spring element 34. The push rod 35 is in this
case arranged on the system housing, the right-hand system housing
half 5 of which is illustrated in FIG. 14.
[0083] FIG. 14 also shows a locking element 36 for a magazine
safety device. This locking element 36 can engage in a
corresponding groove 37 in the push rod 35. The spring element 34
is in the form of an angled spring steel rod, which can absorb the
forces exerted by the user on the trigger when the push rod is
blocked by the magazine safety device.
[0084] The function of the magazine safety device can be seen in
detail from FIG. 24 to FIG. 27. In particular, these figures
indicate that the locking element 36 is in the form of a tab at the
end of a locking lever 54 which can pivot and can be pivoted upward
against the force of a spring 55. Pivoting the locking lever 54
upwards allows the magazine 56 to be inserted (in this context, see
FIG. 26). FIG. 25 and FIG. 27 show that the locking lever 54 pivots
downwards once the magazine 56 has been removed, so that the
locking element 36 can engage in the groove 37, thus preventing a
shot from being fired.
[0085] FIG. 2 and FIG. 3 also show that, despite the rifle
according to the invention being of the Bullpup type, it is
designed such that two holders 38, 39 for magazines, which are not
illustrated, are provided in the rear stock 8.
[0086] In this case, the front holder 38 is used for holding the
magazine that is being used at that time while, in contrast, the
rear holder 39 is used for holding a spare magazine.
[0087] FIG. 2, FIG. 3 and FIG. 20 also show that the rear stock 8
has a cutout 40, which is used as a thumb hole, behind the grip 10.
A longitudinal slot 41 which extends essentially vertically is
provided on the rear face of this cutout 40 in the rear stock 8 in
order to accommodate an unlocking element 53 (in this context, see
FIG. 20 and FIG. 21). This unlocking element 53 is used to unlock
the magazine, so that it can be removed from the cutout 38.
[0088] FIG. 9 and FIG. 10 show a detailed view of the breech
housing 3 with the breech 2 located in it. This shows the view from
the right-hand side, with the rifle being in an assembled
arrangement for right-handed gunners. The rear cutout 12 in the
breech housing 3 is thus closed by a panel 14 on the side which
cannot be seen but is at the rear in FIG. 9 and FIG. 10, although
the inner face of the panel 14 can be seen in FIG. 10. Red markings
42 which can be seen in FIG. 10 are arranged on this inner face of
the panel 14. These red markings 42 can be seen by the gunner when
the breech 2 is pushed forward, with the sear 21 thus being cocked.
The rear face of the panel 14 can thus be used as a cocking
indication.
[0089] FIG. 15 and FIG. 16 show a safety unit 43 in the central
part of the rifle. The safety unit 43 has an operating slide 44 on
each of the sides of the rifle, with the two operating slides 44
being connected to one another. The operating slides 44 have red
safety vanes 45 at their rear ends, which project upwards out of
the stock when the rifle is armed. FIG. 15 and FIG. 16 show the
armed position. The red safety vanes 45 can be seen by the gunner
from above while aiming, thus improving the safety of the rifle.
The safety unit 43 may also have a red dot 46 in a known manner on
the front face of the respective operating slide 44, which likewise
indicates the armed state of the rifle.
[0090] The rifle also has a childproof safety device 47, which can
likewise be seen in FIG. 15. This childproof safety device 47 may
in this case have, in a known manner, a rotating element with, by
way of example, a roof-like external profile which can be operated
only by using a suitable key. The childproof safety device does not
act directly on the trigger, but on the safety unit 43, which
cannot be moved from the safe position to the armed position when
the childproof safety device 47 is locked.
[0091] FIG. 17 to FIG. 19 show a sight 48, which essentially
comprises a sight part 50, which is arranged on a mounting rail 49
on the stock such that it can be moved. The sight 48 is, in
particular, integrated in the mounting rail 49 on the front stock
7. The sight part 50 is shown in FIG. 17 in a position in which it
has been pushed downwards and is thus stowed, while, in contrast,
FIG. 18 shows the sight part 50 pushed upwards, and thus ready for
use. FIG. 19 shows that the sight part 50 has a disk 51 which can
rotate and has grooves 52 arranged on the circumference. The
grooves 52 are in this case used for aiming at a target and are at
different radial distances from the center of rotation of the disk
51. This allows the elevation position of the sight to be adjusted.
FIG. 19 shows that a total of six different grooves are provided on
the disk 51.
[0092] FIG. 22 and FIG. 23 show the connection between the rear
stock 8 and the system housing. Parts of the two system housing
halves 5, 6 are shown for this purpose in FIG. 22. The connection
is made by means of a screw 57 which can be screwed into a
corresponding hole in the system housing halves 5, 6, through the
rear stock 8, from its lower face. The significant feature
according to the invention in this case is that a flexible plastic
part 58 holds the screw 57 in the area of the lower face of the
rear stock 8. The detailed view illustrated in FIG. 23 shows that
the flexible plastic part 58 has two arms 59 which are spaced apart
from one another, run parallel to one another, and can hold the
screw between them. The introduction of the screw results in the
arms 59 being bent away from one another to a certain extent, so
that the clamping force of the arms 59 holds the screw.
