Description
[0001] This application is a divisional of Ser. No. 10/066,566,
filed Feb. 6, 2002.
BACKGROUND OF THE INVENTION
[0002] This invention relates to a fire arm, especially a small
caliber pistol, having a grip, a frame connected to it, a barrel
unit fixed on the frame in the operating state of the fire arm,
with a barrel tube and a bolt which can move relative to the frame
and barrel unit, such that when a shot is fired it can move to the
rear against the direction of firing.
[0003] Fire arms of this type have been known for a long time. In
contrast to large-caliber fire arms, in which there is a locking
means which joins the barrel and the bolt to one another, in small
caliber pistols, generally, the barrel or barrel unit is fixed on
the frame. Large caliber firearms are therefore not encompassed by
the aforementioned generic concept, because in them, the barrel
sits loosely in the locking unit so that when a shot is fired,
first the barrel and bolt, driven by the recoil of the fired round,
traverse a common return path until the bolt separates from the
barrel and subsequently continues its further return path alone. In
a large-caliber firearm, which is generally made in this way with a
locking means, it is possible to replace the barrel tube or barrel
unit by another version of the barrel tube. Firearms with these
locking means for the barrel or barrel unit are, however, generally
very complex and therefore comparatively expensive to produce.
[0004] There is no possibility of changing the barrel in small
caliber pistols, which are generally equipped with a spring-mass
bolt. In these firearms, according to the generic concept, the
barrel unit is fixed on the frame and is permanently attached. It
is permanently attached by fixed injection, or by pinning the
barrel tube to the corresponding frame parts. It therefore is
desirable, in small caliber pistols, i.e. in firearms in which the
barrel tube, or barrel unit, is to be fixed or fixable on the
frame, to be provided with the possibility of changing without in
doing so, the need to choose a costly design, such as that of
choosing a locking mechanism.
[0005] The object of this invention is therefore to devise a
firearm, of the initially mentioned type, which can be economically
produced and which enables the barrel to be changed.
SUMMARY OF THE INVENTION
[0006] Provided is a barrel unit, and/or a frame, which includes
fastening means which allow detachable mounting of the barrel unit
on the frame. In contrast to the existing structures, the barrel
unit is not permanently and, at least for the user, undetachably
joined to the frame, but is detachably mounted on the frame via
fastening means.
[0007] According to one preferred embodiment of this invention, the
barrel unit has a barrel block, which is mounted permanently on the
end of the barrel tube which is the back end in the direction of
firing. The barrel block is mounted together with the barrel tube
on the frame, or can be detached together with the barrel tube from
the frame in order to change the barrel unit. In doing so, on the
barrel block there can be a rise for inserting a round into the
barrel tube and/or an extractor groove for pulling out an empty
shell casing. By providing a barrel block which is made in this
way, when changing and subsequently attaching the barrel unit to
the frame, problems with respect to accurate adjustment of the rise
and the extractor groove relative to the barrel tube are
prevented.
[0008] Advantageously, on the bottom of the barrel block a guide
rib is attached which fits into a guide groove which interacts with
it on the frame when the barrel unit is mounted on the frame. The
guide groove and the guide rib by their interaction ensures
reliable positioning of the barrel unit on the frame. Furthermore,
the interaction of the guide rib and the guide groove result in the
inability of the barrel tube to turn in the frame.
[0009] According to one preferred embodiment of this invention, the
fastening means can include a frame bridge which is attached to the
frame and which has a through hole through which the barrel tube
extends when the barrel unit is mounted on the frame.
[0010] Furthermore, the fastening means can include screw means,
which when joined to one another enable the barrel unit to be fixed
on the frame. Screw means represent a detachable attachment method
which is also easy to manage for the user.
[0011] Preferably the screw means has a barrel nut encompassed by
the barrel unit and an outside thread in the end area of the barrel
tube which is the front area in the direction of firing, and by
screwing the barrel nut onto the outside thread of the barrel tube
the barrel unit can be fixed on the frame bridge. To do this, the
barrel unit also has a barrel jacket which can be slipped from the
front onto the barrel tube such that with its front end it can
adjoin the barrel nut and that at the same time the barrel nut can
be screwed onto the outside thread of the barrel tube. Here, when
the barrel unit is mounted on the frame the barrel jacket from
forward fits on or in the frame bridge, conversely the barrel block
from the back fits on or in the frame bridge so that when the
barrel nut is tightened the barrel jacket, or the barrel block, is
pressed from the front or back against the corresponding contact
surfaces of the frame bridge so that in this way the barrel unit is
securely fixed against the frame. The barrel unit thus acts as a
counter bearing when the barrel tube or the barrel jacket is
screwed onto the frame bridge. Exact axial positioning of the
barrel tube on the frame is thus ensured.
[0012] The firearm includes a magazine safety which allows a shot
to be fired only when the magazine has been inserted into the
firearm. When the magazine is not inserted the magazine safety,
which is pivotally supported on the frame being pressed by a spring
against a connecting rod which can functionally connect the trigger
to a sear which is dynamically joined to the hammer, and the
connecting rod in the state pressed down, a round cannot be fired.
Conversely, when the magazine is inserted, the magazine safety is
pressed upward against the force of the spring so that the
connecting rod likewise moves up into a position such that by
actuating the trigger, a shot can be fired. One such magazine
safety means represents an economical alterative to the magazine
safety means known in the art.
[0013] The firearm includes a trigger lock that can be transferred
out of the position in which the trigger can be actuated, into the
position in which the trigger cannot be actuated. The trigger lock
has an engagement surface which is made as a roof-like surface, and
this engagement surface can be reached through an opening in the
grip from the outside, a wrench being provided which has an
opposing contour which corresponds to the engagement surface. One
such trigger lock, in contrast to the trigger locks known from the
art, can be more economically implemented.
[0014] The firearm has a rear sight which can be transversely
adjusted and which by means of a rear sight mounting is attached on
the rear top of the bolt. The rear sight mounting has an internal
thread which extends in the transverse direction and the rear sight
has a through hole which extends in the transverse direction, and
after placing the rear sight on the rear sight mounting such that
the hole of the rear sight is flush with the internal thread of the
rear sight mounting, a setscrew can be inserted through the hole of
the rear sight into the internal thread of the rear sight mounting
such that by turning the setscrew the rear sight can be adjusted
relative to the bolt in the transverse direction. In contrast to
the adjustable rear sights which are known from the art, the rear
sight as depicted in the invention is made very simple and
economical.
[0015] The firearm, in the rear area of the bolt, has a roller
safety with safety fins which are attached on the outer sides to it
and which can be transferred by catching from the safety-on into
the safety-off position of the roller safety. The safety fins being
produced from a flexible material, especially from plastic. The
locking in the two end positions being achieved by catch cams,
especially in the form of balls, which are mounted accordingly on
the safety fins or on the bolt in the area of the end positions. In
the existing art, the aforementioned balls must be held elaborately
by means of springs in order to reliably ensure locking in the end
positions. In the safety fins as described in the invention, due to
the flexibility of the plastic used, it is ensured that the two
safety fins can also catch in the end positions even without
complex spring holding of the balls.
[0016] The firearm has an breech block which is housed in the bolt
and which is made of steel. Conversely, the bolt is made from a
zinc diecasting, an aluminum, a plastic or a similar light and
economical material. By using the aforementioned economical
materials the production costs of the firearm can be reduced.
[0017] The bolt is made from a zinc casting, an aluminum, a plastic
or a similar light and economical material. Into the side wall of
the bolt, a steel cylinder pin is inserted and is used as wear
protection for a slide catch lever. Here, the production costs of
the firearm can be reduced by choosing economical materials.
[0018] The frame is made from a zinc diecasting, an aluminum, a
plastic or a similar light and economical material. The cylinder
pin which interacts with the connecting rod and which is located on
the frame is made of steel.
[0019] In the bolt, there is a breech block on which a swivelling
loaded state indicator is mounted. This can be viewed, or touched,
from the outside and it indicates to the user, when there is a
round in the barrel, that the firearm is loaded. The loaded state
indicator shows when the firearm is loaded, when one section
adjoining the rear edge of the cartridge. This loaded state
indicator, compared to the loaded state indicators known from the
past, can also be produced much more economically. Furthermore, the
loaded state indicator can be produced from plastic so that it is
possible for the loaded state indicator to safely adjoin the rear
edge of the cartridge.
[0020] The firearm includes a dismounting clip which is movably
held on the frame and in the upper position releases the bolt on
the frame to be able to move and in the lower position releases the
bolt for removal, the dismounting clip being made of an at least
partially elastic material, especially of plastic. The dismounting
clip is also used as an end stop for the corresponding contact
surface of the bolt when the bolt moves to the rear when a round is
fired. Based on the double function of the dismounting clip, a
buffer effect is achieved in firearms without the need for extra
parts.

DETAILED DESCRIPTION OF THE INVENTION
[0039] FIG. 1 shows that a firearm, which is made as a small
caliber pistol, and includes a grip 1, a frame 2, a barrel unit 3
and a bolt 4. The grip 1 on its top has a recess 5 opened to the
top for accommodating the frame 2. The frame 2 in the embodiment
shown, has two parts 2a, 2b which can be connected to one another.
The barrel unit 3 in the embodiment shown, has a barrel block 6, a
barrel tube 7, a barrel jacket 8 and a barrel nut 9. In the
embodiment shown, the barrel block 6 is securely joined to the
barrel tube 7.
[0040] On the frame part of the two frame parts 2b which is the
right-hand one in the direction of firing, the frame bridge 10 is
molded onto its upper side and has a hole 11 which is a through
hole in the direction of firing for accommodating the barrel tube
7, or the barrel jacket 8. The inside diameter of the hole 11, on
the side of the frame bridge, which is the front side in the
direction of firing, is chosen such that the barrel jacket can be
inserted to fit. At a distance within the hole 11, there is a
projection 12 which is used as a stop for the barrel jacket 8,
which is to be inserted from the front into the hole 11.
[0041] The barrel block 6 and the barrel tube 7 are detailed in
FIG. 5. The barrel block 6 includes an essentially cuboidal body 13
with a hole 14 which passes through it in the direction of firing
for accommodating the barrel tube 7. In the firing direction, a
connecting sleeve 15 is molded on the body 13 and its inside
diameter corresponds essentially to the outside diameter of the end
of the barrel tube 7 facing the barrel block 6 so that the barrel
tube 7 can be soldered securely to the connecting sleeve 15 of the
barrel block 6.
[0042] On the bottom of the barrel block, there is a guide rib 16
which extends in the direction of firing and which is used for
fitted installation of the barrel unit 3 in the frame 2, as is
detailed below. On the end of the guide rib 16, facing away from
the barrel tube 7, there is an ascent 17 for inserting a round into
the barrel tube 7. Furthermore, on one of the two sides of the
barrel 13, there is an extractor groove 18 for removing the empty
casing.
[0043] On the frame 2, after its assembly, there is a guide groove
19, of which in FIG. 1 the lateral boundary 20 formed by the
right-hand frame part 2b is apparent. The guide groove is used when
the barrel tube 7 is placed from the rear into the hole 11 of the
frame bridge 10 for lateral fixing of the barrel block 6 by
accommodating the guide rib 16 mounted on the bottom of the barrel
block 6. A detailed view of the guide groove is shown in FIG.
15.
[0044] FIG. 2 shows the barrel tube 7 with the barrel block 6 being
placed in the hole 11 of the frame bridge 10. In particular, the
end of the hole 11 facing the barrel block 6 in the frame bridge 10
has an inside diameter such that the connecting sleeve 15 of the
barrel block 6 can be inserted to fit into this section of the hole
11. After inserting the connecting sleeve 15 into the hole 11, as
far as the body 13 of the barrel block 6 on the back end of the
frame bridge 10, the barrel jacket 8 is slipped onto the barrel
tube 7 from the front until its back end adjoins the projection 12
of the hole 11. Then, the internally threaded barrel nut 9 is
screwed onto the front end of the barrel tube 7, which has an
outside thread (not shown) which matches the inside thread of the
barrel nut 9. By tightening the barrel nut 9, the front end of the
body 13 is pressed against the back end of the frame bridge 10 and,
at the same time, the back end of the barrel jacket 8 is pressed
against the projection 12. This yields a secure seat of the barrel
unit 3 on the frame 2.
[0045] The barrel unit 3 can be changed by loosening the barrel nut
9 and pulling the barrel jacket 8 or the barrel tube 7 out of the
frame bridge 10 and by corresponding insertion and fixation of
another, for example, longer barrel tube and a correspondingly,
likewise, longer barrel jacket.
[0046] FIGS. 6a and 6b show a magazine safety means. FIG. 6a shows
the magazine safety means in the safety-off position, this
safety-off position being achieved by inserting the magazine tube
21 into the firearm. The magazine tube 21, on its top end, on the
outside, has a projection 22 which can press below a magazine
safety 23 which can be swivelled around a horizontal axis. FIG. 6a
shows the magazine safety in its position pressed upward. In this
position, the connecting rod 25, which can be actuated by the
trigger 24, can be pushed to the left, in FIG. 6a, such that a
projection 26, located on the top of the connecting rod 25, can
engage a sear 27, at the top, such that by actuating the trigger 24
a round can be fired.
[0047] Between the top of the magazine safety 23, and a
corresponding projection on the left frame part 2a, or the right
frame part which is not shown, there is a spring 49 by which the
magazine safety 23 is pretensioned down. After removing the
magazine tube 21, the spring 49 presses the magazine safety 23
down, likewise, the connecting rod 25 being pushed down by the
magazine safety 23. This motion of the connecting rod 25 down,
which is apparent from FIG. 6b, ensures that when the trigger 24 is
actuated, the projection 26 of the connecting rod 25 cannot engage
the sear 27, so that by actuating the trigger 24, a round cannot be
fired.
[0048] FIG. 7 shows the attachment of the rear sight 28 on the bolt
4. A rear sight mounting 29 is attached to the rear top of the bolt
4 and corresponds essentially to a cylinder section, which, with
its cut surface, rests on the top of the rear sight 28.
Furthermore, the rear sight mounting 29 in the transverse direction
has an inside thread.
[0049] Accordingly, the rear sight 28 in the transverse direction,
has a through hole, and the rear sight 28 can be placed on the rear
sight mounting 29 such that the hole of the rear sight 28 is flush
with the inside thread of the rear sight mounting 29. Furthermore,
on the top of the rear sight 28, there is a recess for inserting
the rear sight mounting. Furthermore, there is a setscrew 30,
which, when the rear sight 28 has been slipped onto the rear sight
mounting 29, can be screwed through the hole in the rear sight 28
into the inside thread of the rear sight mounting This is indicated
in the exploded drawing in FIG. 7. A retaining disk 31 can be
slipped onto the end of the setscrew 30 which projects on the
opposite end out of the hole of the rear sight 28 and riveted.
[0050] By turning the setscrew 30, the rear sight 28 can be
adjusted in the transverse direction relative to the rear sight
mounting 29 and thus relative to the bolt 4, and the front sight 32
which is attached to the bolt 4. To do this, the recess, in the
rear sight 28 for holding the rear sight mounting 29 in the
transverse direction, is larger than the rear sight mounting 29. In
particular, in the hole in the rear sight 28, a catch projection is
mounted to ensure that the setscrew 30 can be turned with
catching.
[0051] FIG. 7 shows two safety fins 33, which together with a
cylinder-shaped roller safety 34, which can be pushed through the
bolt 4, form a safety unit. As in the existing art, the safety fins
33 can be transferred from a safety-on position, into a safety-off
position. Making the safety fins 33 out of plastic is novel. In the
recesses 36 on the safety fins 33, balls 35 are inserted which
interact with the corresponding recesses on the bolt 4 for catching
in the end positions of the safety fins 33. As a result of the
elasticity of the plastic safety fins 22, the balls 35 need not be
held by wire springs.
[0052] Furthermore, FIG. 7 shows a breech block 37 which is made of
steel. Conversely, the bolt 4 in which the breech block 37 is
installed, is produced from a zinc diecasting, an aluminum, a
plastic, or the like. Thus, an especially stressed part, such as
the breech block 37, is produced from a correspondingly wear-proof
material like steel. Conversely the bolt 4 is made from a
relatively light and economical material.
[0053] A similar consideration leads to the cylinder pin 38 shown
in FIG. 8 and FIG. 9 being made of steel. This cylinder pin 38 is
used as wear protection for the slide catch lever which is not
shown. In turn, an especially stressed part is made from a
resistant material. Conversely, the bolt 4 is made from a zinc
diecasting, an aluminum or a plastic.
[0054] Similarly, the cylinder pin 39 shown in FIG. 1 and FIG. 4 is
made of steel. Conversely, the frame part 2b and the frame part 2a,
are made from a zinc diecasting, an aluminum or a plastic. In turn,
one of the main wearing parts, specifically the cylinder pin 39,
which interacts with the connecting rod 25, is produced from a
wearproof material. Conversely, the other components, with a large
volume, are produced from a light, economical material, such as,
for example, a zinc diecasting.
[0055] In FIG. 10, the trigger lock unit can be removed with a
wrench 40 which can extend through the opening in the grip 1 to the
trigger lock 41 shown in FIG. 11 and FIG. 12. By means of the
wrench 40, the trigger lock 41 can be moved out of the position in
which the trigger can be actuated into the position in which it
cannot be actuated. In particular, FIG. 11 and FIG. 12 show that
the trigger lock 41 is made essentially as a half-cylinder, which,
in the blocked position, can fit into a corresponding
semicylindrical receiver 42 on the trigger 24. The trigger lock 41
is locked here by means of a spring 43 on the frame part 2b.
Furthermore, the trigger lock 41 on its side facing the opening, in
the grip part 1, has a roof-like surface 44 which cannot be gripped
and turned from the outside with tools like screwdrivers, or the
like. The wrench 40 on its end which can be inserted into the grip
part 1, has a correspondingly shaped opposing contour 45. The
trigger lock 41 can only be turned by the wrench 40, particularly
by the rooflike surface 44, and the corresponding opposing contour
45, when the wrench is pressed with a certain force into the
opening on the grip part 1. This offers additional safety.
[0056] FIG. 13a and FIG. 13b show that on the breech block 37, a
loaded state indicator 46 is pivotally mounted which when there is
a round in the barrel indicates to the user that the firearm is
loaded. The loaded state indicator 46 is made of plastic and when
the firearm is loaded adjoins the rear edge of the cartridge.
[0057] FIG. 3 and FIG. 14 show a dismounting clip 47 which in the
firearm, as in weapons from the existing art, is used to movably
hold the bolt on the frame part 2 in the upper position and to
release the bolt for removal in the lower position. In the
embodiment shown, the dismounting clip 47 is used at the same time
as an end stop for the corresponding contact surface 48 of the bolt
4 when the bolt 4 moves to the rear when a round is fired. In the
embodiment shown, the dismounting lever 47 is made from, at least
partially, an elastic plastic so that a buffer effect is achieved
by the contact surface 48 meeting the dismantling clip 47.
