Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is claiming the benefit, under 35 U.S. C.
119(e), of the provisional application which was granted Ser. No.
61/565,110 filed on Nov. 30, 2011 and the provisional application
which was granted Ser. No. 61/615,686 filed on Mar. 26, 2012, the
entire disclosures of which are hereby incorporated by
reference.
BACKGROUND OF THE INVENTION
[0002] A Weaver or Picatinny rail is utilized for attaching various
accessories onto a weapon such as a rifle, shotgun, handgun, or
crossbow. These types of rails typically extend in a generally
longitudinal direction for aligning an accessory parallel to the
weapon bore.
[0003] Typically, the accessory is mounted to the Weaver or
Picatinny rail. Mounts known in the art are clamped together and
may be clamped onto the rail. Thus, these mounts utilize
compressive force to be assembled and/or to be attached to the
rail. Unfortunately, these mounts do not provide the accessory in
exactly the same orientation each time the accessory is mounted. If
the accessory is an optical scope, it is very important that the
orientation of the scope, relative to the gun bore, be consistent
to avoid having to sight in the gun each time the scope is removed
and reattached. Also, known mounts are traditionally made of
materials that can scratch and/or dent the accessory when, for
example, the accessory is mounted to or when the accessory is
removed from the mount.
[0004] Thus, it would be desirable to provide an attachment
assembly, a member for attaching and a method for securing the
attachment assembly to a weapon that allows the accessory to be
consistently and precisely oriented each time the accessory is
mounted. Also, it would be desirable to provide an assembly which
can mount an accessory to the weapon without denting or scratching
the accessory.
BRIEF SUMMARY OF THE INVENTION
[0005] The present invention is directed to a firearm attachment
assembly, a member for the firearm attachment assembly, and a
method for securing an attachment assembly to a weapon.
[0006] In one embodiment, the firearm attachment assembly comprises
an upper mounting portion and a lower mounting portion. Each
portion has an inner surface. Also, the firearm attachment assembly
comprises a layer affixed to and covering at least a portion of the
inner surface of the upper mounting portion and at least a portion
of the inner surface of the lower mounting portion.
[0007] In one embodiment, the member for a firearm attachment
assembly comprises a portion which tapers from a first end to a
middle portion and a threaded portion attached to the middle
portion.
[0008] In one embodiment, the method for securing an attachment
assembly to a weapon comprises providing an attachment assembly.
The attachment assembly comprises a passage formed there through.
Also, the method comprises positioning the attachment assembly over
a slot in a rail such that the passage is aligned with the slot and
inserting a member into the passage and between opposite sides of
the slot to secure the attachment assembly to the rail.

and the lower layer 48 is affixed to the inner surface 42 via an
interlock between the lower overmolding 48 and the lower mounting
portion 36, 36A, 36B, 36C, 36D.
[0046] As shown, for example, in FIGS. 3 and 5, in an embodiment,
the upper overmolding 46 comprises one or more anchor portions 54.
Also, as shown in FIG. 5, in an embodiment, the lower overmolding
48 comprises one or more anchor portions 56, 57. In an embodiment,
the upper overmolding 46 comprises one anchor portion 54 and the
lower overmolding 48 comprises a plurality of anchor portions 56,
57. In these embodiments, the upper overmolding 46 is disposed on
the inner surface 38 and extends from the inner surface 38 to the
outer surface 40 of the upper mounting portion 34. Additionally,
the lower overmolding 48 is disposed on the inner surface 42 of the
lower mounting portion 36 and between the inner surface 42 and the
outer surface 44 of the lower mounting portion 36, 36A, 36B, 36C,
36D. The anchor portions 54, 56, 57 interlock the overmoldings 46,
48 with the upper mounting portion 34 and lower mounting portion
36, 36A, 36B, 36C, 36D, respectively.
[0047] The anchor portion(s) 54, 56, 57 can be of any suitable size
and shape for interlocking the upper overmolding 46 to the upper
mounting portion 34 and the lower overmolding 48 to the lower
mounting portion 36, 36A, 36B, 36C, 36D. In an embodiment, certain
anchor portions 56 may be of generally cylindrical in shape.
However, it should be appreciated that the assembly 30, 30A, 30B,
30C, 30D is not limited to anchor portion(s) 56 having a generally
cylindrical shape. For example, in certain embodiments, an anchor
portion 57 having a generally triangular or frusto-conical shape
may be utilized. Further, it should be appreciated that anchor
portions of different shapes and/or sizes can be utilized together
in certain embodiments.
[0048] In certain embodiments, a neck portion 58, 60 is attached to
an anchor portion 54, 56 on an end of the neck portion 58, 60. On
an opposite end, the neck portion 58, 60 is attached to one of the
layers 50, 52. Thus, the neck portion 58, 60 connects the anchor
portion 54, 56 to the layer 50, 52.
[0049] Preferably, the neck portions 58, 60 have a width 62, 63 and
a length 64, 65. As shown in FIG. 5, the neck portions 60 of the
lower overmolding 48 may be of a generally rectangular shape such
that the length 65 is greater than the width 63 of each neck
portion 60. In other embodiments, certain anchor portions 56 may
have a diameter 66. In these embodiments, the diameter 66 of
certain anchor portions 56 may be greater than the width 63 of the
neck portion 60 attached thereto.
[0050] Preferably, each anchor portion 54, 56, 57 and neck portion
58, 60 is formed in a groove 68, 70, 71 provided in the either of
the upper mounting portion 34 or the lower mounting portion 36,
36A, 36B, 36C, 36D. Each groove 68, 70, 71 comprises walls 72, 74,
75 which are immediately adjacent and may be in contact with an
anchor portion 54, 56 and/or a neck portion 58, 60. In certain
embodiments like the one shown in FIG. 5, an anchor portion 56 and
neck portion 60 may be surrounded by the walls 74 of a groove 70.
In other embodiments, an anchor portion 54 and neck portion 58 may
be at least partially surrounded by the walls 72 of a groove
68.
[0051] The overmoldings 46, 48 may be formed by any suitable
method. For example, the overmoldings 46, 48 may be formed by
machining. However, in certain embodiments, the overmoldings 46, 48
are formed by an injection process. As such, the overmoldings 46,
48 may be formed of materials suitable for being injected into the
grooves 68, 70.
[0052] Preferably, the upper and lower overmoldings 46, 48 are
comprised of materials such that the layers 50, 52 have a hardness
value which is less than that of the upper mounting portion 34 and
lower mounting portion 36,36A, 36B, 36C, 36D. In certain
embodiments, the layers 50, 52 have substantially the same hardness
value. In these embodiments, each layer 50, 52 may have a hardness
value of at least 80 durometers. In other embodiments, each layer
50, 52 has a hardness value of at least 90 durometers. It should be
appreciated that although the layers 50, 52 have a hardness value
which is less than that of the upper and lower mounting portions
34, 36, 36A, 36B, 36C, 36D, the layers 50, 52 are sufficiently
durable for use in mounting an accessory to a firearm and
supporting the accessory over multiple uses.
[0053] When mounted, the accessory is in contact with the layers
50, 52 and held in place by friction. Advantageously, the accessory
is not scratched or dented by the firearm attachment assembly 30,
30A, 30B, 30C, 30D. This is due at least in part to the elasticity,
durability and coefficient of fiction of the layers 50, 52 which is
similar to natural rubber compounds. The material for the layers
50, 52 may also be selected so that the layers 50, 52 can withstand
temperatures of both hot and cold environments.
[0054] Preferably, the upper layer 50 and lower layer 52 are
comprised of the same or substantially the same material(s). In an
embodiment, the upper layer 50 and lower layer 52 may comprise a
composite material. Preferable composite materials for forming the
layers 50, 52 are thermoplastic elastomers such as Santoprene.TM.
or the like.
[0055] As illustrated, for example, in FIGS. 1-5, each layer 50, 52
may be formed in a substantially uniform manner. As such, when the
inner surface 38 of the upper mounting portion 34 and the inner
surface 42 of the lower mounting portion 36, 36A, 36B, 36C, 36D
have a semi-circular shape, the upper layer 50 and lower layer 52
also each have a generally semi-circular shape.
[0056] The assembly 30, 30A, 30B, 30C, 30D comprises an opening 76
between the upper mounting portion 34 and lower mounting portion
36, 36A, 36B, 36C, 36D. The accessory is positioned within the
opening 76 when it is mounted. The opening 76 is defined by the
inner surfaces 38, 42 of the upper and lower mounting portions 34,
36, 36A, 36B, 36C, 36D. When the upper layer 50 and lower layer 52
are affixed to the inner surfaces 38, 42 of the upper and lower
mounting portions 34, 36, 36A, 36B, 36C, 36D, the opening 76 is
defined or at least partially defined by the layers 50, 52.
[0057] As-noted above, the inner surfaces 38, 42 of the upper and
lower mounting portions 34, 36, 36A, 36B, 36C, 36D and the upper
and lower layer 50, 52 of the overmoldings 46, 48 may each have a
semi-circular shape. In these embodiments, the inner surfaces 38,
42 and/or the layers 50, 52 align to provide the opening 76 with a
circular or generally circular shape. However, while the opening 76
preferably has a circular shape, the assembly 30, 30A, 30B, 30C,
30D is not limited to a circular opening. As such, the opening 76
may be of a generally rectangular, elliptical, triangular, or of
another shape. It should also be noted that the dimensions of the
opening 76 are not particularly limiting. Thus, the attachment

144C travels through the space 174C until the pin portion 144C
contacts the stop 176 located at the end of the receiving portion
170C, 172C. The stop 176 prevents the pin portion 144C from further
travel through the receiving portion 170C, 172C, respectively.
[0083] As shown in FIG. 18, when both legs 86C, 88C are attached to
the lower mounting portion 36C, the method of attachment may
comprise rotating at least one of the legs 86C, 88C vertically
about an axis of rotation 142C. In the embodiment shown in FIGS. 19
and 20, both legs 86C, 88C can be rotated vertically about an axis
142C. Rotation of the legs 86C, 88C can be limited in an upward
direction by providing a crest 178 adjacent each receiving portion
170C, 172C or by another portion of the lower mounting portion 36C.
The amount of rotation or limitation thereto can be selected. Thus,
the size and shape of each crest 178 can be selected to provide a
desired amount of rotation or limitation thereto. Similarly,
opposing end portions 180 of the sidewalls 108 or other portions of
the lower mounting portion 36C can be utilized to limit the
rotation of the legs 86C, 88C about their respective axis of
rotation 142C in the opposite direction.
[0084] The method of attachment may also comprise providing the
lower mounting portion 36C over the rail 500 as shown in FIGS.
19-21. Specifically, in an embodiment, the lower mounting portion
36C may be provided such that it is positioned over any one of the

opening 76 of the assembly 30C is axially aligned with the rail
500.
[0085] The method of attachment may also comprise rotating at least
one leg 86C, 88C to provide at least one leg 86C, 88C adjacent the
rail 500. If both legs are rotatable, then the method may comprise
rotating both legs 86C, 88C such that the legs 86C, 88C are
provided adjacent the rail 500. As shown in FIG. 20, after rotating
the at least one leg 86C, 88C, the first leg 86C is separated from
the second leg 88C by the rail 500. A gap 182 may be provided on
both sides of the rail 500 between the first leg 86C and the rail
500 and the second leg 88C and the rail 500 as shown.
[0086] As depicted in FIG. 20 and above-discussed, the legs 86C,
88C are aligned with the lower mounting portion 36C and the rail to
provide a pathway which extends from one side 96 to an opposite
side 98 of the lower mounting portion 36C and through the rail 500.
In the illustrated embodiment, the pathway comprises the passage
94C. The passage 94C is positioned such that it is aligned with a
slot in the top of the rail 500. The method of attachment may
comprise positioning the threaded portion 138 of the member 122
adjacent one end of the passage 94C as shown.
[0087] To secure the firearm attachment assembly 30C to the rail
500, the member 122 is inserted into the pathway. As shown in FIG.
21, after the member 122 is inserted into the passage 94C, the
member 122 is transversely disposed through the firearm attachment
assembly 30C. Insertion of the member 122 into the pathway also
positions a portion of the member 122 between opposite sides of the
slot. Positioning a portion of the member 122 between opposite
sides of the slot provides an interference fit between the member
122 and the slot such that the assembly 30C cannot move along the
longitudinal direction along the rail 500. When the wedge member
122 is utilized and inserted through the passage 94C, the top
surface of the tapered portion contacts a top surface 184 (shown in
FIG. 18) of the passage 94C and the flat bottom surface of the
tapered portion contacts a bottom surface 186 (shown in FIG. 17) of
the passage 94C. Contact by the wedge member 122 acts on the
passage 94C such that a force is exerted on at least a portion of
the top and bottom surfaces 184, 186 of the passage 94C to secure
the elements of the firearm attachment assembly 30C together and
the assembly 30C to the rail 500.
[0088] The method may also comprise rotating the nut 126 onto the
threaded portion 138 of the member 122. In certain embodiments, a
washer (not depicted) may be provided between the nut 126 and the
outer surface of the first leg 86C.
[0089] After securing the lower mounting portion 36C to the rail
500, the screws 82 may be removed from the assembly 30C. Removing
the screws 82, allows the upper mounting portion 34C to be detached
from the lower mounting portion 36C. As above-noted, when mounting
an accessory to the rail 500, two or more firearm attachment
assemblies 30C may be secured to the rail 500. Thus, two or more
lower mounting portions 36C may be first secured to the rail 500.
After detaching the upper mounting portions 34C from the lower
mounting portions 36C, the accessory may be positioned on the lower
overmoldings 48. Next, the upper mounting portions 34C are
positioned over the accessory such that the upper overmoldings 46C
contact the accessory. Subsequently, the upper mounting portions 24
are attached to the lower mounting portions 26 by reinserting the
screws 82.
[0090] By way of any of the above-described embodiments, the
firearm attachment assembly 30, 30A, 30B, 30C, 30D consistently and
precisely orients an accessory each time the accessory is mounted
without scratching or denting the accessory.
[0091] In accordance with the provisions of the patent statutes,
the principles and modes of operation of this invention have been
described and illustrated in its preferred embodiments. However, it
must be understood that the invention may be practiced otherwise
