Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of priority under 35
U.S.C. .sctn.119 of German Patent Application DE 10 2013 003 906.1
filed Mar. 8, 2013, the entire contents of which are incorporated
herein by reference.
FIELD OF THE INVENTION
[0002] The invention relates to a butt plate for a gun, in
particular for a long gun, comprising a monopod.
BACKGROUND OF THE INVENTION
[0003] Long guns, in particular for precise shooting over long
distances, usually require a stable three-point support when
firing. This is often achieved in practice in that a so-called
bipod is attached to the fore-end of the gun, which can be folded
down when needed. The third support point is often formed by the
end of the butt stock which is placed on a solid base.
[0004] Further, a monopod is known which is integrated in the butt
stock of a gun and can be pulled out when needed so as to adjust
the height of the third support point. This does significantly
improve accuracy, but subsequent attachment to any type of gun is
not always possible or produces aesthetically unpleasant
results.
SUMMARY OF THE INVENTION
[0005] Starting from this state of the art, it is the object of the
present invention to provide a butt plate with an integrated
monopod which has a simple structure, provides high accuracy and
can be subsequently mounted to almost any gun with different butt
shapes in a simple and easy manner.
[0006] This object is attained by a butt plate according to the
present invention.
[0007] First of all, the butt plate of the present invention for a
gun, in particular for a long gun, comprises an intermediate piece
to be attached to the rear side of the butt of the gun facing
toward the shooter and a plate made of a recoil-damping material,
which can be attached to the side of the intermediate piece facing
toward the shooter. A monopod is accommodated in a recess of the
intermediate piece in a slidable manner such that the monopod can
be moved from a position in which it is substantially arranged
within the recess into at least a second position in which an end
of the monopod protrudes out of the intermediate piece in such a
manner that the butt can be supported on a solid base by means of
the monopod. According to the invention, the intermediate piece is
substantially made of a machinable material. In other words, this
means that it can be adapted to different butt geometries in an
easy manner by simply regrinding the intermediate piece so that, on
the one hand, an aesthetically pleasing unity of gun and butt plate
is produced and, on the other hand, almost any gun can be
retrofitted with a butt plate of this kind.
[0008] In this context, any material can be used as long as
sufficient machinability is ensured. Preferably, however, the
intermediate piece is made of a plastic material, in particular of
polyoxymethylene (POM). Also, it is advantageous if the plastic
material is through-colored because then an unchanged surface color
is maintained after machining as intended.
[0009] The monopod can basically be formed in any given manner and
can be embodied by a threaded bolt, for example, which can be
screwed into and out of the intermediate piece. According to a
preferred embodiment of the invention, however, the monopod
comprises a pod element and a pin element, the pod element being
provided with latching elements on its outer side and having a
forwardly open recess at least in sections, said recess being
provided with an inside thread into which a pin element can be
screwed. In other words, the monopod is formed in two parts with a
pod element and with a pin element that can be screwed into the pod
element. Thus, the adjusting range can be enlarged overall because,
for example, the pod element can initially be pulled out entirely
and when it has reached its end position the pin element can
additionally be screwed out.
[0010] According to a particularly preferred embodiment example of
the invention, the latching elements of the pod element are formed
by the turns of a trapezoidal thread arranged on the outer side of
the pod element, the inside thread being formed as a fine thread at
the same time. Thus, at first, a coarse or quick adjustment of the
monopod can be performed by pulling or screwing out the pod element
and a subsequent fine adjustment can be achieved by screwing the
pin element in or out of the fine inside thread of the pod
element.
[0011] To lock and adjust the butt plate, a locking element is
provided according to a particularly preferred embodiment of the
invention, said locking element being arranged in a second recess
running transversely to the longitudinal axis of the first recess
in such a manner that at least one latching tooth of the locking
element can be brought into engagement with the latching elements
of the pod element and can be released again from said engagement
by means of an actuating element. Thus, a coarse or quick
adjustment of the pod element can be performed in a particularly
easy and fast manner by a simple sliding motion.
[0012] According to a preferred embodiment example of the
invention, the locking element is provided with a recess running
transversely to its longitudinal axis, said recess being engaged by
the pod element, the latching tooth being arranged in the area of
the inner wall of the recess. The recess can have a closed
circumference in the manner of a through bore, the locking element
completely surrounding the pod element, or it can be formed as a
recess open to one side, said recess surrounding the pod element
only at one side.
[0013] To achieve a reliable and smooth coarse and fine adjustment,
in particular also when the locking element is not actuated,
according to another embodiment example of the invention, the
latching tooth is arranged angularly on the locking element in such
a manner that its inclination substantially corresponds to the
pitch of the trapezoidal thread. In other words, this means that
the latching tooth represents a very short section of a mating
thread of the trapezoidal thread, said section causing an axial
motion of the pod element when the pod element is rotated and thus
causing a rotation out of or into the intermediate piece.
[0014] In the simplest manner, the latching tooth can be integrally
molded to the locking element, in particular to the inner wall of
the recess. According to another embodiment example of the
invention, however, the locking element comprises a dowel pin which
is arranged in a bore that opens radially in sections to the recess
of the locking element, the dowel pin protruding into said recess
with its outer circumferential surface, thus forming the latching
tooth. On the one hand, this leads to an increased protection of
the latching tooth against mechanical damage and, on the other
hand, this facilitates production of the locking element.
[0015] To ensure a secure locking position of the locking element,
according to another embodiment example of the invention, at least
one spring element is provided in the second recess, said spring
element pressing the locking element against the latching elements
of the pod element when the actuating element is not actuated. The
locking engagement can be released in a simple manner by pressing
the locking element against the spring force of the spring
element.
[0016] According to another embodiment example, for actuating the
locking element, the actuating element is formed by an axial end of
the locking element which is formed as an actuating button. The
actuating button and the locking element can be formed as one piece
or instead the actuating button is arranged as a separate element
on the locking element and is attached thereto.
[0017] According to a particularly preferred exemplary embodiment
of the invention, at least the actuating button--preferably,
however, the entire locking element--is also made of a machinable
material, in particular of polyoxymethylene (POM). In this way, the
geometry of the actuating element, too, can be adapted to the shape
of the intermediate piece and thus to the shape of the butt,
wherein it can be achieved that the actuating element protrudes
slightly out of the intermediate piece so as to achieve improved
tactility or also that the actuating element is substantially flush
with the contour of the intermediate piece or even arranged in a
slightly recessed manner so as not to compromise the appearance of
the gun.
[0018] For attaching the intermediate piece to the butt of the gun,
the intermediate piece can have at least one through bore to be
engaged by at least one fixing screw for attaching the butt plate
to the butt of the gun. Preferably, several bores of this kind are
provided in various positions so as to permit attachment to
different guns and butts. Further, at least one threaded bore is
provided on the intermediate piece for attaching the plate made of
recoil-damping material.
[0019] The plate made of a recoil-damping material can basically be
made of any material as long as a sufficient damping of the recoil
forces occurring when firing is ensured. Preferably, however, the
plate is substantially made of natural rubber, synthetic rubber or
of a rubber mixture and is screwed or vulcanized to the
intermediate piece. In particular, it is another advantage of these
materials that they can be machined, in particular be grinded into
shape, so that an adaptation to the butt and to the gun can also
take place in the area of the plate.
[0020] The various features of novelty which characterize the
invention are pointed out with particularity in the claims annexed
to and forming a part of this disclosure. For a better
understanding of the invention, its operating advantages and
specific objects attained by its uses, reference is made to the
accompanying drawings and descriptive matter in which preferred
embodiments of the invention are illustrated.

[0028] FIG. 7 is a schematic view of the butt plate of FIG. 3 with

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0029] Referring to the drawings in particular, the butt plate
illustrated in FIG. 1 has an intermediate piece made of a
dimensionally stable material, e.g. of plastic or metal, in
particular of a light metal alloy. Said intermediate piece 1, which
is connected to the actual butt plate (not shown for the sake of a
clearer illustration) or integrally molded into it, serves to
attach the butt plate to the gun on the one hand and to accommodate
the pull-out monopod on the other hand For attachment to the butt
of the gun, the intermediate piece 1 is provided with fixing bores
2 and 3 to be engaged by fixing screws.
[0030] For accommodating the monopod, the intermediate piece 1 has
a recess 4 which extends through the entire length of the
intermediate piece 1 and is open to both sides. The recess has a
first section 6 and a second section 7 with different
diameters.
[0031] A first pod element 5 can be inserted into said recess 4
from the first side. The substantially cylindrical pod element 5
has an outer diameter substantially over its entire length which is
at least slightly smaller than the inner diameter of both sections
6 and 7 of the recess 4.
[0032] In the area of its end, the pod element 5 is provided with a
collar-like projection 8 whose diameter is larger than the inner
diameter of section 7, but at least slightly smaller than the
diameter of section 6. In other words, this means that, at maximum,
the pod element 5 can protrude into section 6 of the intermediate
piece only so far until the collar-like projection 8 comes to bear
against the upper annular area 9 of section 7. Thus, the pod
element 5 is in particular precluded from dropping out.
[0033] The pod element 5 is provided with latching elements on its
outer side. In the embodiment example illustrated in FIG. 1, said
latching elements are represented by a trapezoidal thread 10, which
substantially extends across the entire axial length of the pod
element and which is only indicated by a dashed line.
[0034] In the area of the lower section 7 of the recess 4, a
locking element 11 is arranged, which engages into the lower
section via a recess 12 running transversely to the longitudinal
axis of said recess 4 and penetrates said lower section entirely.
Said locking element 11, which is illustrated in more detail in
FIG. 2, has an arched recess 16 and a latching tooth 14 at the end
of said arched recess 16 facing away from the actuating end 13. The
latching tooth 14 is formed and sized in such a manner that it can
engage into the trapezoidal thread 10 of the pod element 5 with its
end.
[0035] A spring element 18 is arranged between the end 15 of the
locking element 11 and the bottom 17 of the recess 12, said spring
element 18 forcing the locking element 11 in the recess 12 to the
outside. If now, for mounting the device according to the
invention, the locking element 11 is first pressed toward the
inside into the recess 12 against the spring force, the pod element
5 inserted in the recess 4 can penetrate the locking element 11
within the recess 12 with its shaft. If the locking element 11 is
let go now, the latching tooth 14 of the locking element 11 engages
into the trapezoidal thread 10 of the pod element 5 because of the
reset force of the spring 18 so that the pod element 5 is locked in
its axial position and the locking element 11 is simultaneously
secured against dropping out. By actuating the locking element by
means of the button 18, the lock can be released and the pod
element 5 can be axially adjusted as needed.
[0036] The pod element 5 is provided with a forwardly open inside
thread 20. A second pin element 21, which is provided with a
corresponding outside thread, can be screwed into and out of said
inside thread 20. Thus, in a simple manner, first, a coarse
adjustment of the monopod can be performed by means of the locking
element and the trapezoidal thread of the pod element 5, to be
potentially supplemented by a fine adjustment by means of the
inside thread 20, which is preferably formed as a fine thread, and
by means of the pin element 21.
[0037] For the adaptation to different butt shapes, both the
intermediate piece 1 and the actuating button 19 can be made of a
material that can be brought into the appropriate shape by
machining and grinding, e.g. of an easily machinable plastic
material.
[0038] The embodiment example illustrated in FIGS. 3 to 7 basically
has the same structure as the embodiment example illustrated in
FIGS. 1 and 2. As can be taken in particular from FIG. 3, the butt
plate has an intermediate piece 22 which can be attached to the
butt of a gun (not illustrated) by means of through bores 23. As a
finish on the side facing toward the shooter, the butt plate
according to the invention further comprises a plate 24 made of a
recoil-damping material, in this case of rubber, which can be
screwed to the intermediate piece via two fixing screws 25. The
fixing screws 25 penetrate the rubber plate 24 in indicated through
holes 26 and engage into threaded bores 27 in the intermediate
piece 22.
[0039] The intermediate piece 22 has a recess 28 extending across
its entire length, said recess 28 having two sections with
different diameters in correspondence to the embodiment example of
FIG. 1. In the area of the section with the smaller diameter, a
second recess 29 in the shape of a blind hole is provided, said
recess 29 extending transversely to the longitudinal axis of the
first recess 28 and intersecting the same. In said recess, a
locking element 30 is arranged, which will be explained in more
detail in the following.
[0040] The locking element 30 has a substantially cylindrical base
body, which has a recess 31 that runs transversely to its
longitudinal axis and can be penetrated by the pod element 32. The
recess 31 is formed in the manner of a long hole with the longer
axis extending in the direction of the longitudinal axis of the
locking element 30. The front end of the locking element 30 facing
to the outside is formed as a button-type actuating element 33 by
means of which the locking element can be pressed into the recess
31 against the force of a spring device (illustrated only
schematically) formed by two spiral springs 34. The spiral springs
34 are supported with one end on the bottom of the recess 31 formed
like a blind hole and with their other end on the front end 34 of
the locking element 30 lying opposite of the actuating element 33.
For this purpose, the locking element comprises two recesses 35
into which the spiral springs 34 engage.
[0041] Further, the locking element 30 has a recess 36, which forms
a flange-like supporting surface 37 around the recess 31. Said
supporting surface serves as a stop for the collar-like projection
38 at the upper end of the pod element 32 so that the latter cannot
drop down out of the locking element and thus out of the butt plate
as a whole.
[0042] As can be seen in particular in FIG. 4, the locking element
30 has a bore 39 that extends transversely and in an offset manner
with respect to the longitudinal axis of the locking element 30.
The bore 39 is arranged angularly to a horizontal plane through the
center longitudinal axis of the locking element 30, the inclination
of the bore 39 substantially corresponding to the pitch of the
trapezoidal outside thread 40 of the pod element 32. In sections,
the bore 39 has an opening 44 which is oriented toward the recess.
A dowel pin (not illustrated) can be inserted into said bore 39 and
protrudes with its outer circumferential surface radially into the
recess 31 of the locking element 30, forming a latching element or
a latching tooth.
[0043] If now the locking element is introduced into the recess 29
of the intermediate piece 22 and is penetrated by the pod element
32, the locking element 30 is pressed to the outside by the reset
force of the spiral springs 34 so that the dowel pin and thus, in
the terms of the present application, the latching tooth is brought
into a latching engagement with the trapezoidal thread 40 of the
pod element 32 so that it is axially fixed in a defined position.
If the locking element 30 is now pressed toward the inside into the
recess 29 by means of the actuating element 33, the latching tooth
moves out of its engagement with the trapezoidal thread 40 so that
the pod element 32 as a whole can be moved in the direction of the
axis. Instead of sliding it axially, the pod element can also be
adjusted by rotating in its position relative to the intermediate
piece 22 because of the inclination of the latching tooth, the
latter taking on the function of a stationary thread nut.
[0044] As can be taken from FIG. 3, a pin element 41 is further
provided, which has an outside thread and which can be screwed into
an inside thread complementary in form and function within the pod
element 32. At its end, the pin element is provided with a
ball-shaped support element 42, which can be screwed onto the pin
element 41 in an exchangeable manner by means of a thread 43.
[0045] In the position shown in FIG. 5, the monopod composed of pod
element 32 and pin element 41 is shown highly schematically in the
retracted position. It is schematically indicated that the bottom
side of the intermediate piece 22 can be provided with an enlarged
opening of the recess 28 to allow a partially covered placement of
the support element in the intermediate piece, in particular for
aesthetic reasons. In the position shown in FIG. 6, the pod element
32 is completely extended into its final position, which is defined
by the pod element 32 abutting with its collar-like projection 38
against the flange-like support surface 37 of the locking element.
In FIG. 7, at last, the monopod is shown in an almost completely
extended position, in which the pin element 41, too, is screwed out
of the pod element.
[0046] For adaptation to different butt shapes on different guns,
the butt plate according to the illustrated embodiment example can
be machined, for example, by grinding the outer contours of the
intermediate piece 22, of the plate 24 and of the actuating element
33 so that a butt plate according to the invention can be mounted
to virtually any gun by replacing the existing butt plate.
[0047] While specific embodiments of the invention have been shown
and described in detail to illustrate the application of the
principles of the invention, it will be understood that the
invention may be embodied otherwise without departing from such
principles.
