Automatic Pistol
The invention relates generally to automatic pistols; particularly the
invention relates to an
automatic pistol comprising a hammer which is movable by a slide, a removable
magazine, a rod
which is movable together with the hammer, and an insert into which the free
end of the rod
enters during its movement. The insert has a lock which is set to prevent
movement from the
rod.
This type of pistol is known from US 5 081 779 (PACK). Automatic pistols of
this type are built
by the applicant, but have already been known with these features since the
beginning of the
century (for example, Colt model 1911). The insert in principle is already
known through the
Browning model 1903 and makes it possible to machine and assemble the
components that form
a blind shaft to accommodate the striker spring on the back side of the grip,
since the blind shaft,
like the shaft to accommodate the magazine, could not be produced by
broaching.
This problem no longer exists in many modem automatic pistols, since the
pistol stock is mass
produced from plastic in one piece in an injection molding process. However,
the insert has
generally been retained since it forms the stop for the striker spring: it is
possible with such an
insert to assemble the advance mechanism of the weapon without it being loaded
by the striker
spring during assembly. The insert is incorporated subsequently, on which the
striker spring is
supported, and this is placed under tension on this account.
A simple design is always sought in military weapons in the interest of
reliability. However,
civilian customers often desire more extensive safety features. It is,
therefore, generally
necessary to design a civilian version, independent of mass production of
military weapons,
which naturally makes their manufacture more expensive. However, additional
safeties are also
often required subsequently by customers for military weapons. An effort is,
therefore, made to
CA 02353811 2001-06-07
find safety devices that permit simple equipping, and especially retrofitting,
of a weapon that did
not previously have such a safety.
One such safety is the safety against unauthorized use.
Small arms, say, for game protection, self defense or the like, must, in
principle, be unloaded
when they are not carried and reliably protected from any unauthorized access.
However, years
of habit often lead to a certain casualness, so that the loaded weapon is
merely placed in a
weapons cabinet and this often only inadequately secured. Thus, it is common
in automatic
pistols to remove the magazine and place it next to the weapon. However, the
loaded weapon is
often merely put away safely, perhaps in a drawer or on a shelf.
It is, therefore, not ruled out that the weapon ready for use can fall into
the hands of unauthorized
persons. These can be children, who can threaten themselves and others with
the weapon; but
also burglars, who can then use the weapon during their burglary or even
later.
Other persons, say, household employees, once they have gained knowledge of
the location of
safekeeping of the weapon, can also steal it, perhaps to commit a crime.
Persons often make sure, merely by briefly removing the magazine, whether it
contains
cartridges. If this is the case, the weapon is then put away or carried for
actual use without
further examination. A thorough functional test is generally dispensed with.
A revolver is known (US 2 945 316 and Bock-Weigel, Handbook of Small Arms,
1989, page
139) that attempts to remedy the above problem. In this revolver a lock with
key is inserted in
the bottom stem of the pistol stock, with which a rod connected to the hammer
(the guide rod for
the striker spring) can be blocked when the hammer is uncocked, so that the
hammer can no
longer be cocked. It can then no longer be fired.
This known revolver is certainly not secure against theft, but is secure
against unauthorized use.
The (quite small) key for this lock can be worn by the owner of the weapon,
perhaps on a chain
around the neck, where it is inaccessible to unauthorized persons.
2
CA 02353811 2001-06-07
However, the lock can be opened or circumvented quite easily. Because of its
limited design
dimensions and the required robustness (the recoil during firing must not
adversely affect the
function of the lock), the key is not designed to open tumblers, but is not
much more than a
screwdriver for turning the lock. This lock can, therefore, be turned with an
appropriate tool,
even without a key, and, therefore, opened. Moreover, the handle escutcheons
can be removed
so that the lock is accessible from the side and can be lifted out or
otherwise made unusable.
Finally, the spring guide rod blocked by the lock can also be simply filed off
when the handle
escutcheons are removed. Because of this, during cocking of the revolver,
disorders can occur,
but when it is first cocked, it can be fired without difficulty.
Since the lock is applied on the bottom clearly visible in the pistol stock,
it is immediately
recognized, even on cursory examination, and, if necessary, disabled in one of
the above
mentioned ways, in order to make the weapon ready for use.
A closing cylinder is known from the generic DE 39 37 042, which sits in the
magazine
accessibly from the bottom and controls a slide that engages in the insert and
prevents movement
of the rod. The fact that the magazine capacity is reduced is a particular
drawback.
Another shortcoming of the known locks lies in the fact that the components to
be rotated by
means of the key have an axis of rotation that runs roughly across the
direction of shooting. The
inertial forces occurnng during firing, therefore, run roughly tangentially to
these components
and attempt to rotate them accordingly, if they are unbalanced. If such a
lock, through long use
or frequent fiddling, is slightly worn, there is thus the hazard that the lock
will automatically lock
after a shot is released. Because of this, further use of the weapon becomes
impossible
unexpectedly and in undesired fashion, until the lock has been unlocked again.
The closing cylinder of DE 39 37 042 for children and untrained persons
represents an obstacle
that can scarcely be overcome. Moreover, the mounting of such a lock in the
vicinity of the
hammer makes filing off of the spring guide rod impossible. Reliable
attachment of the lock in
the frame also poses at least no fundamental difficulties. However, the pistol
stock must then be
redesigned. The safety lock and the necessary modifications to the weapon are
also quite cost-
intensive.
3
CA 02353811 2004-12-06
The drawback just described is still not really eliminated, as long as a
person, who manages to
get his hands on the weapon secured by the lock, can recognize at a glance
that the weapon is
secured and how it is secured. He will then set about getting around this
safety, say, by
routinely drilling out the closing cylinder and releasing the lock.
The known proposal to arrange measurement sensors and electronics on a pistol
that only permit
use when a certain hand line pattern is recognized is not feasible. The
authorized user would
even be precluded from use if he were to wear a glove or wound bandage, or if
his hand were
badly soiled.
Another safety is the so-called magazine safety: this blocks the weapon when
the magazine is
removed. It is precisely civilians who remove the magazine when a pistol is
put away, but
then no longer pay attention to the cartridge in the barrel. A magazine safety
prevents an
accident from happening during handling of the presumably unloaded pistol.
Known magazine safeties are mostly connected to the trigger and advance
mechanism. They
have a feeler that extends into the magazine shaft, which activates the
interrupter when it is not
pressed back by the introduced magazine. These magazine safeties increase the
complexity of
the necessary devices and, in so doing, necessarily reduce their reliability.
The task of the invention is to modify the automatic pistol mentioned at the
outset, in order to
eliminate at least some of the aforementioned weaknesses of the prior art.
In particular, the invention is to offer a way to incorporate, in simple
fashion, even by
retrofitting, one of the above safety aspects in an already existing design of
an automatic pistol of
the type mentioned at the outset.
This method should be implementable preferably in a simple, robust and
reliable manner.
This task is solved according to the invention by the fact that the generic
pistol mentioned at
the outset has a projection that is set up to prevent movement of the rod, and
that this projection
is incorporated in the insert.
4
CA 02353811 2004-12-06
The revolver with lock mentioned at the outset also has a device to block the
rod. But this is
incorporated in its own reinforced frame, and at a location that is generally
reserved for the
magazine in an automatic pistol.
On the other hand, in the invention the projection for blocking the rod is
incorporated in an
insert, as was used previously in the known, generic automatic pistol. During
assembly of the
pistol, it is then only necessary to incorporate the insert according to the
invention instead of the
previous insert, in order to create a pistol, which, deviating from the
generic one, is capable of
preventing cocking of the hammer or, optionally, advance of the cocked hammer
(if the
projection engages, say, in a notch of the rod).
The insert can have a releasable detent. The detent, however, can also be
designed permanent
and nonreleasable, so that cocking or advance is prevented. Such a detent can
be mounted or
removed as required, preferably by means of a wrench-like tool. In the last
named case, the
automatic pistol according to the invention is equipped with a closable lock.
The detent, which is arranged in the insert or formed by it, however, can also
be unreleasable, so
that the automatic pistol can be made unusable by replacing an existing known
insert with the
detent insert according to the invention. This possibility is important, say,
for gun stores, which
keep weapons in display windows; likewise, for police and the military for
safekeeping of stored
weapons; also for transport of weapons and much more: should a store thief get
hold of a pistol
with a detent insert from the display window, or should he attempt to take a
weapon presented
for inspection and escape with it, there is no hazard that he will load the
weapon with carried
ammunition and use it to make good his escape. With the police or military,
the personnel
responsible for safekeeping of weapons cannot take a weapon in order to use it
privately.
Likewise, an employee of a transport company cannot misuse a weapon along the
way for
shooting practice. None of these things work, because the weapon is, indeed,
properly
assembled, but does not fire. The inserts that permit functioning of the
weapon must naturally be
kept far away from the secured pistols, under lock and key. Replacement of the
inserts and thus
arming of the pistols is a trivial matter, even for a layman, when he is shown
how.
CA 02353811 2004-12-06
The detent is preferably designed as a lock in the broader sense. For this
purpose, it has a lock
that engages in its end position behind the rod or engages in a projection of
the rod; moreover, a
wrench-like tool. A closing cylinder is generally not provided, since it is
too sensitive to the
high loads to which it is exposed.
However, to hamper abusive use, the invention takes a completely different
and, in weapons, a
thus far unusual path, concealing the lock from the view of unauthorized
persons so that it
cannot even be seen, so that the weapon is secured from unauthorized use. The
engagement
projection of the lock, in which the key must be inserted for activation, is
preferably arranged so
that the unknowing and unauthorized user does not recognize the presence of a
detent. Only on
the occasion of intended use is it found that the pistol does not function.
However, there can be
many reasons for this. In any event, he will not manipulate the lock, since he
is not even aware
of it. The aforementioned solution with the replaceable insert that prevents
firing also offers the
same advantage.
It must be noted here that the applicant is expressly reserving its claim for
separate protection
for the invisible, perhaps concealed, application of the detent and not only
on automatic pistols,
but also on hunting, sport and military weapons of all types. The detent need
not act merely on
the rod, but can also act on any other element, whose securing or moving is
suitable for
preventing use of the weapon.
A fairly simple and robust lock to secure an automatic pistol against
unauthorized use is known
from the already mentioned US 5 081 779 (PACK) (Figures 14 to 16), which sits
in a replaceable
insert so that this is optionally replaceable if no lock is desired. However,
the lock can be
opened with simple means and an unauthorized person can also establish, by
glancing at the
weapon, that is has a lock so that he can make the lock ineffective for
unauthorized use or open
it.
The subsequent modifications of this concealed application of the lock or
detent should also
acquire independent protection.
6
CA 02353811 2004-12-06
Thus, it is possible, for example, to provide a transversely running threaded
hole in a sport
weapon with a cylinder closure in the frame, in which an Allen screw 6, which
can be turned by
means of an Allen wrench, sits in a recess of the slightly opened closure. In
the tightened state,
the screw lies so deeply in the hole that it cannot be recognized from the
exterior without
difficulty. It then penetrates into a counter-projection, so that the closure
is secured. If the screw
is unscrewed again by means of the wrench, it is again visible from the
outside and the closure is
released, so that the weapon is ready for use.
A modification of the invention consists of providing a cover to render the
lock invisible. In
the case just described, the cover could be a screw with a short shaft, which
is screwed into
the hole in front of the stud screw.
An unauthorized user, who has gained access to an automatic pistol according
to the invention
and convinced himself, by checking the magazine, of its usability, will only
find that this use is
not possible when he intends to fire the weapon.
Even if an unauthorized user intends to test the weapon for use and then finds
that it does not
function, he will deem it defective and attempt to take it apart. However,
this generally will not
be possible, since, with the detent fixed with the uncocked hammer, this is
blocked and removal
of the slide is prevented. In no case will he be prompted to act on the lock,
since he cannot
assume that such a lock exists. The possible existence of such a lock is, at
best, familiar to the
technical personnel of a gun shop or one skilled in the art of small arms.
It is, therefore, ruled out that the weapon can be used by unauthorized
individuals immediately
or a short time after its theft. A simple, small and robust lock can be used,
which is much more
cost-effective than an expensive safety lock. If children or adolescents have
stolen the weapon,
after discovery of the defect of the weapon, the limited group of people
generally involved here
will decide that the weapon can be returned before an accident has happened.
It is perhaps possible, in the simplest case, to arrange the lock as in a
revolver mentioned at the
outset, but to recess it slightly so that it is accessible through a hole that
can be closed by a
7
CA 02353811 2004-12-06
plastic plug. This plastic plug can be adapted in color and design to the
parts surrounding it, so
that it is not recognized as a removable part. For unblocking or blocking, the
plug must be
removed, perhaps with a fingernail, in order to provide access to the key.
During purchase of the
weapon, several plugs can be provided from the outset, so that, in the event
of damage or loss, a
replacement is still available. However, the problem of a possible effect of
inertial forces on the
lock is still unsolved. These can act on a lock and displace it, when it is
unbalanced and its axis
runs across the direction of recoil.
The invention, therefore, proposes, in a preferred embodiment, to tilt the
lock by 90° and thus
arrange it so that it runs roughly parallel with its axis of rotation to the
direction of firing of the
weapon. Inertial forces that occur as a result of firing and are aligned
parallel to the direction of
firing, therefore, act on the rotatable parts of the lock in the axial
direction and are, therefore, not
capable of rotating these parts. Instead, they are pressed axially into their
mount and are thus
securely fixed during the action of the inertial forces.
The key in this case can be introduced from the back side of the pistol stock
after the cover
provided there has been removed.
However, the invention proposes, in a preferred embodiment, that the magazine
be designed as a
cover, i.e., that the engagement projections provided for use of the key be
arranged on the back
side of the magazine shaft. The bottom of the magazine is generally beveled so
that the front side
of the magazine shaft lies higher than its front side. If the lock is arranged
in the lowermost
section of the magazine shaft on its back side, a straight key can then
conveniently reach the lock
when it is passed along the lower front edge of the magazine shaft. It is even
advantageous to use
the mentioned front edge as a support, in order to introduce the key reliably
into the projection of
the lock.
These projections are then always protected from soiling and view, as in the
case of a different
cover.
It is pointed out that the magazine shaft in automatic pistols is generally
only limited rearward by
guides, but not by a closed wall. The insert forms on the lower end the guide
and walls form the
8
CA 02353811 2004-12-06
magazine shaft. The insert is, therefore, freely accessible from the magazine
shaft, but poorly
recognizable.
However, the insert can also form a magazine safety; a feeler, forced by a
spring into the empty
magazine shaft, activates the detent in the insert; if the magazine is
introduced, the feeler is
forced or pushed in by the magazine and it releases the detent. With this
expedient, the weapon
is simultaneously blocked from firing when the magazine is removed. It cannot
be fired.
The outside dimensions of the different inserts (previous insert without
additional function, insert
with permanent detent, insert with releasable detent or lock, insert with
magazine safety) are the
same. All other relevant features in conjunction with the invention (length of
the spring guide
rod, design and length of the striker spring, hole in the rear wall of the
magazine shaft) are also
preferably of the same design in all types of pistols (with or without lock,
permanent detent,
magazine safety), so that ultimately the insert with lock or the like can also
be furnished
afterward as a retrofitting component for already existing pistols, which
still do not have the
modification according to the invention.
A kit, consisting of pistol and at least two different inserts, is also an
object of the invention.
The rod is then preferably intended as a spring guide rod for the coiled
striker spring. However,
it is also possible, in other striker springs, to hinge the hammer to a
separate rod, whose only
purpose is to cooperate with the lock.
The pistol stock itself is preferably designed in one piece, together with the
handle escutcheons,
perhaps of reinforced or unreinforced plastic. Thus, it is not possible to
remove the handle
escutcheons and act on the then recognizable lock.
The object of the invention is further explained with reference to the
enclosed schematic
drawings. In the drawings:

The same reference numbers denote the same components in all figures.
Fig. 1 shows, in a longitudinal section, an automatic pistol 1 manufactured by
the applicant. This
pistol 1 has, in the usual manner, a magazine 3, which is introduced to a
magazine shaft formed
in a pistol stock 13.
A hammer 5 is mounted to pivot in pistol stock 13, on which a rod 7 acts from
below, which is
loaded by a striker spring 9, which is designed as a coiled spiral spring, on
which the rod is
pushed, supported with its upper end on an upper widening of the rod and
supported on an insert
11 with its lower end. The lower end of rod 7 is designed square and sits in a
square blind hole
19 (Figures 3, 4, 5, 7, 8), which extends downward in insert 11 and is open on
the top.
A lock 17 is formed in insert 11, which will be described in greater detail
later. The lock 17 can
assume two positions, namely, a blocking position, in which it blocks the
square hole 19, and a
release position, in which it releases the square hole 19.
The hammer 5 is shown in Fig. 1 in the uncocked position; the rod 7 is then
pushed upward by
the striker spring 9; the lower end of the rod only penetrates slightly into
the square hole 19 (see
CA 02353811 2001-06-07
also Fig. 2). If the hammer 5 is cocked, i.e., pivoted in the view of Fig. 1
by about 60°
clockwise, then it presses rod 7 against the force of striker spring 9
downward and the square end
of rod 7 penetrates farther down into square hole 19. If the lock 17 with the
uncocked hammer 5
is in the locking position, it blocks the square hole 19 so that the rod 7
cannot be moved
downward, since it is stopped with its square end against lock 17.
Consequently, hammer 5 is
blocked in the position shown in Fig. 1 and this, in turn, blocks the slide
(no reference number)
of pistol 1, so that the pistol 1 can neither be cocked nor disassembled.
If, on the other hand, the lock 17 is in the release position, it releases the
square hole 19 and the
square end of rod 7 can enter this square hole 19 unhampered, when the hammer
5 is cocked.
The pistol is then capable of use.
Beneath the end of square blind hole 19 the insert 11 has a transverse hole 29
that can be brought
into flush alignment with a transverse hole of the same diameter in pistol
stock 13. A pin 15
passes through both transverse holes, in which it sits with transition fit or
with slight press-fit in
the transverse hole of pistol stock 13. The part of pin 15 penetrating insert
11, however, is offset
relative to its ends and has a smaller diameter.
During assembly, the insert 11 is pressed into the pistol stock 13 against the
force of striker
spring 9, until the two mentioned transverse holes are precisely aligned. The
pin 15 is now
pushed in. If insert 11 is now released, the striker spring 9 acts on it and
forces it downward and
outward again, until the wall of its transverse hole 29 sits on the section of
the pin 15 with a
smaller diameter. During an attempt to push the pin 15 out again, this reaches
a stop position on
the side surface of the insert 11 on the edge of the transverse hole 29
belonging to this with the
recess between its larger and smaller diameter. The pin 15 can, therefore,
only be forced out
again if the insert 11 is forced against the force of the striker spring 9
into pistol stock 13, until
the transverse holes are precisely aligned.
Removal and incorporation of the insert 11 can thus be carried out
effortlessly and quickly, but
only when one knows how this is to be done; it is not possible to simply knock
out pin 15, at
least not without causing serious damage.
Insert 11 has guide pieces 21 on both sides (Figures 4 and 6), which are
pushed into
complementary grooves in pistol stock 13 and, together with pin 15, secure
insert 11. The front
11
CA 02353811 2001-06-07
surface 25 of insert 11 forms its back wall on the lower end of the magazine
shaft. The lower
end of insert 11 is designed as a stub or belt eyelet 23.
The pistol stock 13 is manufactured in one piece from a highly loadable,
impact-resistant plastic;
the insert also consists of this material.
Apart from lock 17, the above description of pistol 1 and insert 11
corresponds to the prior art.
The insert 11, in a first variant, is now described with reference to Figures
3 to 14.
The insert 11 has a receiving hole 27, which serves to accept the lock 17, is
displaced laterally
relative to the square hole 19 (Figures 6 and 8) and forms a narrowed neck 31
toward the front
surface 25; neck 31 and receiving hole 27 are coaxial and both are
cylindrical. A snap-in hole 33
runs parallel to transverse hole 29, has a distinctly smaller diameter than it
and intersects the
receiving hole 27 off center near neck 31 (Fig. 8).
The lock 17 is also formed by a cylindrical snap-in block 35, which has a
coaxial, cylindrical
neck piece 37 with smaller diameter. The snap-in block 35 fits rotatably in
receiving hole 27 and
the neck piece 37 in neck 31, in which the radial end surface of the end piece
37 with the front
surface 25 of insert 11 and the radial end surface of snap-in block 35 with
the rear surface of
insert 11 are closed flush.
The snap-in block 35 has a radial depression 41 adjacent to neck piece 37,
which is bounded by
the two rectangular surfaces of snap-in block 35 (see Fig. 10). These
rectangular surfaces lie
behind the square hole 19 after incorporation of snap-in block 35 and insert
11, the axis of which
runs perpendicular to the axis of snap-in block 35.
The snap-in hole 33 is penetrated by a spring pin 43, which lies under slight
pretension against
one of the rectangular surfaces. If the snap-in block 35 is rotated, the apex
between the two
rectangular surfaces runs above the spring pin 43 in its longitudinal
direction, in which this is
elastically bent, and the spring pin 43 then reenters one of the rectangular
surfaces, so that a
bistable locking is formed.
12
CA 02353811 2001-06-07
In one of the locking positions of snap-in block 35 the peripheral surface of
snap-in block 35
opposite depression 41 (position of Fig. 7) closes the square hole 19, so that
the rod 7 cannot
enter the square hole 19. In the other locking position (Fig. 8) the square
hole 19 is released.
Fig. 8 shows section VIII-VIII in Fig. 7, but the lock 17 is situated in Fig.
7 in the locking
position, but in the released position in Fig. 8.
The free radial surface of the neck piece 37 has two engagement-blind holes 45
opposite each
other with the same radial spacing, into which counterpieces on the end of a
tool (Fig. 14) can
engage.
If one removes the magazine 3 from the pistol 1 depicted in Fig. 1, the
extension of the axis of
rotation of snap-in block 35 and neck piece 37 then pass just beneath the
extension of the front
and lower end edge of the magazine shafts. If the tool depicted in Fig. 14 is
introduced with its
engagement pins into the engagement holes 45 of lock 17 and neck piece 37, the
center axis of
the tool runs coaxial to the snap-in block 35 and neck piece 37, in which the
tool lies against the
front lower edge of the pistol stock 13 and is guided. By rotating the tool,
the snap-in block is
switched between its two locking positions, i.e., lock 17 is switched between
its blocking
position and its release position. Spring pin 43 ensures proper holding of the
blocks, so that the
lock cannot leave the release position, for example, during a shot as a result
of shaking of the
weapon. Cooperation of the components of the lock can best be gleaned from the
exploded view
of Fig. 13.
Fig. 15 shows another variant of the insert, which is designated there with
reference number 47.
Insert 47 has an only very short blind hole 53 (instead of square hole 19). If
this insert 47 is
incorporated instead of the generic insert in the prior art, then rod 7 sits
with its lower end in the
short blind hole 53, which centers rod 7, but does not permit downward
movement. Insert 47,
therefore, prevents cocking of hammer S and thus use of weapon 1. This insert
is inserted during
storage, shipment or display of pistol 1. If the pistol is sold, issued to a
soldier or policeman or
received by another recipient, the insert 47 is removed in the aforementioned
manner and
replaced by an ordinary insert.
Fig. 16 shows another variant of the insert, which is designated there with
reference number 49.
This insert 49 has a feeler 51, which is forced into the magazine shaft with a
spring (not shown).
13
CA 02353811 2001-06-07
If the magazine 3 is introduced to the magazine shaft, it lies against the
front surface 25 and then
presses feeler 51 in the direction of the arrow into the insert 49.
The feeler 51 intersects, for example, the square hole 19, and has a notch; if
the feeler 51 is
forced in (magazine 3 in magazine shaft), the notch coincides with the hole 19
and the rod 7 can
enter this. If the feeler 51 is in the depicted (removed) position, then the
magazine is removed,
the shaft of feeler 51 intersects hole 19 and prevents movement of rod 7.
The rod 7, in turn, also has a notch, through which the shaft of the feeler 51
can pass in blocking
fashion when the hammer is cocked and the rod 7 is in its lowermost position.
It is, therefore,
possible to secure the pistol 1, even when it is cocked and the magazine 3 is
removed, since the
hammer 5 cannot strike, because the fixed rod 7 does not transfer the force of
striker spring 9.
However, it is possible that the catch holding hammer 5 cocked is released,
but then the hammer
will only fall into a safety catch when the magazine 3 is introduced.
