Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a recoil dampening device,
and in particular to a recoil dampening device for reducing the
forces exerted onto a gun sight during the operation of an
associated firearm.
[0002] Recoil absorbing devices are used in a variety of
applications within firearms to reduce the forces as exerted on
various portions of the firearm as well as the operator. These
recoil dampening devices typically include at least two or more
parts movable with respect to one another and a recoil dampening
device positioned so as to absorb the forces as generated during
operation of the firearm.
[0003] Heretofore, recoil dampening devices have included multiple
components that are difficult to assemble and/or require special
tools for assembly and/or adjustment, thereby making assembly and
adjustment of the recoil dampening devices difficult in high
pressure situations typically associated with military operations.
In addition, these recoil dampening devices are not suitable for
mating with standardized military equipment. Specifically, these
recoil dampening devices are not compatible with the
"picatinny-style" mounting configuration. Further, previous recoil
dampening devices utilized for mounting a sight base or scope mount
onto a firearm do not sufficiently reduce the recoil associated
with high caliber firearms.
SUMMARY OF THE INVENTION
[0004] One aspect of the present invention is to provide a recoil
dampening sight base that includes a first rail member adapted to
fixedly mount to a firearm, wherein the first rail member has an
elongated body portion and a pair of mounting flanges extending
outwardly from and longitudinally along the body portion, and a
second rail member having an elongated, downwardly opening channel
that slidably receives the body portion of the mounting flanges of
the first rail member therein, and wherein the second rail member
is adapted to releasably support a gun sight thereon. The recoil
dampening sight base also includes at least one elastically
deformable recoil absorbing member disposed between the first rail
member and the second rail member, wherein the recoil absorbing
member is adapted to reduce the recoil transferred from the firearm
to the gun sight when the firearm is fired.
[0005] Another aspect of the present invention is to provide a
firearm for reducing the recoil as transferred to a gun sight
mounted thereon, including a body portion of a firearm having an
upper surface, a first rail member fixedly mounted to the upper
surface of the firearm, wherein the first rail member has an
elongated body portion and a pair of mounting flanges extending
outwardly from and longitudinally along the body portion, and a
second rail member having an elongated, downwardly opening channel
that slidably receives the body portion of the mounting flanges of
the first rail member therein. The firearm also includes at least
one elastically deformable recoil absorbing member disposed between
the first rail member and the second rail member, wherein the
recoil absorbing member is adapted to reduce the recoil transferred
from the firearm to the gun sight when the firearm is fired, and a
gun sight releasably mounted with the second rail member.
[0006] Yet another aspect of the present invention is to provide a
recoil dampening device for a gun sight that includes a first rail
member adapted to fixedly mount to a firearm, wherein the first
rail member has an elongated body portion and a pair of mounting
flanges extending outwardly from and longitudinally along the body
portion, and a second rail member having an elongated, downwardly
opening channel that slidably receives the body portion and
mounting flanges of the first rail member therein, wherein the
second rail member also has at least one receiving rail that
includes a substantially square shaped body portion and a pair of
substantially triangularly shaped mounting flanges extending
outwardly from the body portion, and wherein the second rail member
is adapted to slidably receive a gun sight thereon. The recoil
dampening device also includes a pair of recoil absorbing members
juxtaposed across a length of the first rail member and disposed
between the first rail member and the second rail member, wherein
the recoil absorbing members are adapted to reduce the recoil
transferred from the firearm to the gun sight when the firearm is
fired.
[0007] These and other advantages of the invention will be further
understood and appreciated by those skilled in the art by reference
to the following written specification, claims and appended
drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] For purposes of description herein, the terms "upper,"
"lower," "right," "left," "rear," "front," "vertical,"
"horizontal," and derivatives thereof shall relate to the invention
as oriented in FIG. 1. However, it is to be understood that the
invention may assume various alternative orientations and step
sequences, except where expressly specified to the contrary. It is
also to be understood that the specific devices and processes
illustrated in the attached drawings, and described in the
following specification are exemplary embodiments of the inventive
concepts defined in the appended claims. Hence, specific dimensions
and other physical characteristics relating to the embodiments
disclosed herein are not to be considered as limiting, unless the
claims expressly state otherwise.
[0013] The reference numeral 10 (FIG. 1) generally designates a
recoil dampening device for mounting a gun sight 12 onto a firearm
14. In the illustrated example, firearm 14 includes a firearm
typically associated with military use, however, recoil dampening
device 10 may be utilized with numerous firearms regardless of
configuration or use.
[0014] The recoil dampening device 10 (FIG. 2) includes a first
rail member 16 adapted to fixedly mount to firearm 14, and a second
rail member 18 slidably mountable upon first rail member 16. First
rail member 16 includes a first end 19 and a second end 21. First
rail member 16 also includes an elongated body portion 20 and a
pair of mounting flanges 22 extending outwardly from and
longitudinally along body portion 20. Body portion 20 of first rail
member 16 is defined by a flat bottom surface 24, substantially
flat sidewall surfaces 26 extending perpendicularly from bottom
surface 24 and a triangulated top surface 28. Flanges 22 extend
outwardly from sidewall surfaces 26 and are defined by a bottom
surface 30 and a sidewall surface 32. The top surface of each
flange is coplanar width and blends into top surface 28 of body
portion 20. First end 19 and second end 21 of first rail member 16
each include an aperture 34 (FIG. 3) extending into body portion
20.
[0015] The second rail member 18 includes a first end 36 and a
second end 38. Second rail member 18 is defined by a bottom surface
40, sidewall surfaces 42 and a top surface 44. Second rail member
18 also includes an elongated, longitudinally extending, downwardly
opening channel 46 that slidably receives first rail member 16
therein. Channel 46 includes a main channel section 48 configured
to slidably receive body portion 20 of first rail member 16
therein, and a pair of outwardly extending side channel sections 50
adapted to slidably receive flanges 22 of first rail member 16
therein. Second rail member 18 also includes a receiving rail 56
that includes a pair of substantially triangularly shaped mounting
flanges 58 extending outwardly from sidewall surface 42 and
juxtaposed across second rail member 18. Receiving rail 56 is
adapted to slidably receive a sight mount thereon as described
below. A plurality of gaps or notches 60 along receiving rail 46
and top surface 44 of second rail member 18 divides receiving rail
56 into a plurality of sections, thereby allowing for mid-length
mounting of gun sight 12 as described below.
[0016] The dampening device 10 also includes a first stop member 64
and a second stop member 66 located within channel 46 near first
end 36 of second rail member 18 and second end 38 of second rail
member 18, respectively. Each stop member 64 and 66 are provided
with cross-sectional geometries similar to that of first rail
member 16. Each stop member 64 and 66 are provided with a laterally
extending aperture adapted to threadably receive an associated
locking screw 70 therein, thereby fixing each stop member 64 and 66
from sliding within channel 46 when each locking screw 70 abuts a
sidewall thereof. In assembly, locking screws 70 may be accessed
within channel 46 of second rail member 18 via a pair of apertures
72 extending from sidewall surface 42 to channel 46 of second rail
member 18.
[0017] The dampening device 10 also includes a pair of recoil
dampening members 74 juxtaposed along the length of first rail
member 16 and located within apertures 34 located at the ends
thereof. In the illustrated example, dampening members 74 includes
a pair of coil springs, however, other elastically deformable
material capable of absorbing the recoil as generated by firearm 14
may be utilized.
[0018] In assembly, mounting hardware 76 are located within a
plurality of countersunk apertures 78 extending from top surface 28
to bottom surface 24 of first rail member 16 and affixed first rail
member 16 to firearm 14. Second rail member 18 is slidably
connected with first rail member 16 such that first rail member 16
is located within channel 46 of second rail member 18. Dampening
members 74 are located within apertures 34 of first rail members 16
and held in place when stop members 64 and 66 are located within
channel 46 of second rail member 18 and affixed thereto as
described above.
[0019] The sight mount 60 (FIG. 3 and 4) includes a pair of holding
mechanisms 80 adapted to securely hold a gun sight such as a scope
82 securely therein. It should be noted that holding mechanisms 80
may include any structure capable of fixedly holding a gun sight
such as scope 82 while mating with a "picatinny-style" rail. As
illustrated, sight mount 60 also includes a downwardly extending
attachment arm 84. Attachment arm 84 includes a longitudinally
extending channel 86 having a cross-sectional geometry that
slidably receives receiving rail 56 therein. The width of arm 84 is
provided such that arm 84 can be received within notches 62 between
each section of receiving rail 56, thereby allowing sight mount 60
and the associated gun sight such as scope 82 to be mounted upon
dampening device 10 by slidably attaching arms 84 of sight mount 60
with receiving rail 56 of second rail member 18 without requiring
sight mount 60 to be slid the entire length of second rail member
18. Each arm 84 includes an aperture 88 adapted to threadably
receive a locking screw (not shown) therein, to affix sight mount
60 to second rail member 18.
[0020] In operation, recoil generated by the operation of firearm
14 is lessened or eliminated as the dampening members 74 absorb the
recoil from between first rail members 16 and second rail member 18
in effect increasing the amount of dissipation time for the
acceleration/decelerati- on forces as exerted by the firearm (14
onto the gun sight 12, typically occurring during the first 1.5 to
2 milliseconds subsequent to discharge of the firearm 14.
Specifically, a recoil force in a direction indicated by arrow 90
is exerted on dampening device 10 when a charge within firearm 14
is detonated, thereby causing the compression of first dampening
member 74 between first stop member 64 and first rail member 16 as
first rail member 16 slides rearwardly within channel 46 of second
rail member 18. The recoil force 90 is absorbed by first dampening
member 74, thereby lessening the amount of recoil force 90 as
transmitted to second rail member 18 and thus the gun sight
supported thereby such as scope 82. A reactionary recoil force 92
is exerted onto dampening device 10 as firearm 14 recoils away from
the operator. Recoil force 92 causes a compression of second
dampening member 75 between second stop member 66 and first rail
member 16 as first rail member 16 slides forwardly within channel
46 of second rail member 18. The recoil force 92 as transmitted to
scope 82 is again reduced by the compression of second dampening
member 75.
[0021] The present inventive recoil dampening sight base provides a
more durable sight base having an uncomplicated design that can be
easily and quickly assembly without the use of specialized tools.
The recoil dampening device is further capable of a long operating
life, and is particularly well adapted for the proposed use as it
is compatible with geometrical configurations such as the
"picatinny-style" rail.
[0022] In the foregoing description, it will be readily appreciated
by those skilled in the art that modifications may be made to the
invention without departing from the concepts disclosed herein.
Such modifications are to be considered as included in the
following claims, unless these claims by their language expressly
state otherwise.
