DESCRIPTION
[0020] Various embodiments will be described in detail with
reference to the drawings, wherein like reference numerals
represent like parts and assemblies throughout the several views.
Reference to various embodiments does not limit the scope of the
claims attached hereto. Additionally, any examples set forth in
this specification are not intended to be limiting and merely set
forth some of the many possible embodiments for the appended
claims.
[0021] FIG. 1 is a side view of an example firearm system 90. In
this example, the firearm system 90 includes a firearm 100, a scope
102 and an accessory mount 104. The illustrated scope 102 is
secured to the firearm 100 with the accessory mount 104. The
illustrated firearm 100 can be any firearm that fires projectiles,
such as bullets or shot, and can support a scope with a mount. For
example, the illustrated firearm 100 can be a rifle, a shotgun or a
pistol. The illustrated firearm 100 is defined by an upper receiver
and a lower receiver, and includes a barrel, a trigger and a
stock.
[0022] The illustrated scope 102 can be any scope that functions to
enhance the accuracy of a user's aim while using the firearm 100.
The illustrated scope 102 can have a central narrow mounting
section extending between front and rear expanded magnification
sections containing lenses.
[0023] The illustrated accessory mount 104 functions to secure the
scope 102 to the firearm 100. The accessory mount 104 can be
secured to the upper receiver of the firearm 100, for example to a
mounting rail. The illustrated accessory mount 104 can have a pair
of rings, front and rear, that support the scope 102. The rings of
the illustrated accessory mount 104 receive the narrow section of
the scope 102. The illustrated accessory mount 104 can
alternatively support a variety of different accessories used with
firearms, for example cylindrical accessories such as laser
sights.
[0024] Another example firearm system 90 includes the firearm 100
and the mount 104, but does not include the scope 102. In this
example, the firearm system 90 is configured to receive a scope
102, or other accessories, but the scope is not included.
[0025] FIG. 2 is a perspective view of a mount 120 which can
function similarly to the mount 104 illustrated in FIG. 1. The
illustrated mount 120 can have a mounting base 108, a rear mounting
ring 106a and a front mounting ring 106b.
[0026] The illustrated mounting base 108 has a front end and a rear
end. The illustrated mounting base 108 can have a fastener 116, or
plurality of fasteners, that receives and secures to a firearm. The
fastener of the illustrated mounting base 108 can secure to an
upper receiver of a firearm, for example through a mounting rail
mounted to the firearm.
[0027] The illustrated rear mounting ring 106a is secured to and
extends upwardly from the rear end of the mounting base 108. The
illustrated front mounting ring 106b is secured to and extends
upwardly from the front end of the mounting base 108.
[0028] The illustrated rear mounting ring 106a can have an internal
passageway 114a defined by a lower receiver 112a and an upper cap
110a. The lower receiver 112a and the upper cap 110a are separable
from each other and can be secured to each other with a fastener
118a or plurality of fasteners, for example a tightening screw and
nut, or clip. The illustrated internal passageway 114a can have a
shape resembling a circle to snugly engage an accessory, such as a
scope, that is secured therein. The illustrated lower receiver 112a
can define a lower section of the internal passageway 114a and the
upper cap 110a can define the upper section of the internal
passageway. In use, the upper cap 110a is disengaged from the lower
receiver 112a so that a section of an accessory can be set within
the lower section of the internal passageway 114a within the lower
receiver. The upper section of the internal passageway 114a, as
defined by the upper cap 110a, is then set around the accessory, so
that the upper cap engages the lower receiver 112a on either side
of the accessory. A fastener 118a, or fasteners, is then tightened
between the upper cap 110a and the lower receiver 112a to ensure
that the accessory is secured within the internal passageway
114a.
[0029] The illustrated front mounting ring 106b can be
geometrically and functionally similar to the rear mounting ring
106a described above. The rear mounting ring 106a and the front
mounting ring 106b function together to receive and support the
scope described with respect to the rear mounting ring.
[0030] The illustrated front mounting ring 106b can have an
internal passageway 114b defined by a lower receiver 112b and an
upper cap 110b. The lower receiver 112b and the upper cap 110b are
separable from each other and can be secured to each other with a
fastener 118b or fasteners, for example a tightener screw and nut,
or clip. The illustrated internal passageway 114b can have a shape
resembling a circle to snugly engage an accessory, such as a scope,
that is secured therein. The illustrated lower receiver 112b can
define a lower section of the internal passageway 114b and the
upper cap 110b can define the upper section of the internal
passageway. In use, the upper cap 110b is disengaged from the lower
receiver 112b so a section of the accessory can be set within the
lower section of the internal passageway 114b within the lower
receiver. The upper section of the internal passageway 114b, as
defined by the upper cap 110b, is then set around the accessory, so
that the upper cap engages the lower receiver 112b. A fastener 118b
or fasteners is then tightened between the upper cap 110b and the
lower receiver 112b to ensure that the accessory is secured within
the internal passageway 114b.
[0031] In order to maintain accuracy of aiming an accessory, such
as a scope or laser sight, that would be mounted to a firearm by
the illustrated mount 120, it is important that the rear internal
passageway 114a and the front internal passageway 114b are
concentrically aligned and oriented with respect to a common axis.
Such concentric orientation and alignment reduces any errors
between the direction of an accessory and the direction of a
firearm.
[0032] A raw piece of aluminum can have internal stresses which are
imparted when an extrusion is created. By machining a large amount
of material, such as the gap between two scope rings for use on a
firearm, small springing or distortions can occur. Example methods
for manufacturing firearm accessory mounts can cause inaccuracies
when using the mount on a precision weapon. An example inaccuracy
includes how the accessory clamps interact with bases. In one
example, the accessory clamps (the small pieces which retain the
accessory from the top) are machined separately from the cradle. By
doing so the surfaces which clamp and secure the accessory are not
concentric to each other, causing uneven clamping force on the
accessory, for example the scope tube. Additionally, another error
occurs in that the bore of one accessory ring is not concentric to
the bore of the other ring on the same mount. Accordingly,
additional improvements are desired which reduce the stresses
during manufacturing to ensure a high level of accuracy during
operation.
[0033] FIG. 3 illustrates an example method 140 for making a
firearm accessory mount. In this example, the method includes
operations 150, 152, 154, 156, 158, and 160. In some embodiments
the operations 150, 152, 154, and 156 are performed by a
manufacturer, while the operations 158 and 160 are performed by
another, such as by an installer or an end user, for example. In
another embodiment, the method 140 may be entirely perfumed by the
manufacturer. In yet other embodiments, the operations may be
divided among several people or companies.
[0034] In this example the method 140 begins with an operation 150
in which a material is secured. In some embodiments the material
can be rigid and durable, yet able to be extruded and cut into, for
example plastic or metal. More specifically, the example material
can be aluminum or steel. The material can be secured 150 with a
machining clamp, for example a fixing device with a pair of
opposing jaws that tighten toward each other, or a vice. In another
possible embodiment, the material is held in an alternative manner
that achieves positional stability, such as during the subsequent
forming operation 154. Securing 150 the material allows a user to
maintain an exact orientation or the material during the remaining
steps of the method 140. An example of operation 150 is illustrated
and described in further detail with reference to FIGS. 4 and
5.
[0035] The operation 152 is performed to shape the material. In
some embodiments the shaping includes generating accessory rings
and a mounting rail. In an example illustrated in further detail
herein, two accessory rings are formed that are aligned along a
common axis. The accessory rings are left connected at bottom ends
to a mounting rail that extends between the two accessory rings.
The shaping operation 152 is performed with the material secured in
the securing operation 150. The shaping operation 152 can be
performed with a shaper that forms and shapes the metal from the
raw extrusion form into a predetermined geometry. An example shaper
can be a lathe and a CNC machine. The shaping operation 152
transforms the raw extrusion of material into the general geometry
of an accessory mount. An example of the shaping operation 152 is
illustrated and described in further detail with reference to FIGS.
6 and 7.
[0036] The operation 154 is performed to form apertures through the
accessory rings. In some embodiments the aperture is formed along a
single axis and from one direction. In some embodiments the
accessory rings are concentric with each other along the single
axis. The forming operation 154 can be completed with a forming
tool that forms apertures in the accessory rings. An example
forming tool can be a lathe, a boring machine or a drill bit. The
forming operation 154 is performed with the material secured in the
securing operation 150. An example of the operation 154 is
illustrated and described in further detail with reference to FIGS.
8 and 9.
[0037] The forming operation 154 is completed after the shaping
operation 152 in at least some embodiments to reduce springing or
distortion between the accessory rings. If the apertures were
formed before the accessory ring shaping process, springing or
distortion can result in misalignment of the aperture from one
accessory ring to the other.
[0038] The operation 156 is performed to substantially divide the
formed accessory rings into bases and caps. The dividing operation
156 can be performed with a dividing tool which divides metal, for
example a saw or a laser. The dividing tool can divide the pair of
accessory rings along a common plane so that the bases are
identical and the caps are identical. The caps are retained onto
the bases with a thin sliver section of undivided material that is
not divided by the dividing tool. The dividing operation 156 is
performed with the material secured in the securing operation 150.
The dividing operation 156 is completed after the forming operation
154 to ensure alignment and consistency of geometry between the
accessory rings. By completing the forming operation 154 of the
accessory rings with the bases and caps still connected, the
aperture concentricity is maintained allowing for a tighter fit to
the accessory. Also, any stresses or movement which occurs during
the shaping operation 152 of the material does not adversely affect
the final product, such as misalignment of the caps and the
bases.
[0039] The operation 158 is performed to snap the caps apart from
the bases. The snapping operation 158 can be completed by breaking
the section of undivided material between the bases and caps. A
user can perform the snapping operation 158 manually by hand. The
snapping operation 158 can be performed separately from operations
150, 152, 154 and 156, for example by an end user to which the
shaped, formed and divided scope mount has been removed from the
securing device and delivered.
[0040] The operation 160 is performed to buff or sand the
snapped-apart bases and caps to remove any residue of the undivided
material. The buffing operation 160 can be performed with a buffing
tool, for example with a buffing wheel or sanding wheel. The
buffing operation 160 is performed after the snapping operation
158. The buffing operation 160 can be performed separately from
operations 150, 152, 154 and 156, for example by an end user to
which the shaped, formed and divided accessory mount has been
removed from the securing device and delivered.
[0041] FIG. 4 illustrates an example of the securing operation 150
described in FIG. 3. FIG. 4 illustrates a securing device 210, a
machine 212, a shaping tool 214 and a raw extrusion of material
216. As illustrated, a raw extrusion of material 216 secured in a
securing device 210, for example a clamp. The illustrated raw
extrusion of material 216 can have an elongated block-like geometry
that extends along an axis X. A machine 212 that powers alternative
interchangeable tools, such as drill bits, is illustrated to secure
and operate a shaping tool 214 for shaping the raw extrusion of
material 216. An example shaping tool 214 can be a machining bit
operable within the machine 212.
[0042] FIG. 5 illustrates an example of the securing operation 150
described in FIG. 3, and illustrated in FIG. 4, as viewed along a
different orientation. FIG. 5 illustrates a securing device 210, a
machine 212, a shaping tool 214 and a raw extrusion of material
216. As illustrated, the raw extrusion of material 216 is secured
in the securing device 210 so that the machine 212 can use the
shaping tool 214 to shape the raw extrusion of material into a
different geometry.
[0043] FIG. 6 illustrates an example of the shaping operation 152
described in FIG. 3. FIG. 6 illustrates a securing device 210, a
machine 212, a shaping tool 214, a raw extrusion of material 216, a
mounting base 217 and a pair of accessory rings 218. The raw
extrusion of material 216 remains secured in the securing device
210. The shaping tool 214 powered by the machine 212 is shown to
have shaped a section of the raw extrusion of material 216 into a
pair of accessory rings 218 separated along, and supported by a
mounting base 217. The pair of accessory rings 218 and mounting
base 217 can have geometries resembling the pair of accessory rings
and mounting base illustrated in FIG. 2. As depicted, the pair of
accessory rings 218 are aligned concentrically along the axis X. An
unshaped portion of the raw extrusion of material 216 is not
removed from the securing device 210 during shaping by the shaping
tool 214. The shaping tool 214 shapes the raw extrusion of material
216 into the pair of accessory rings 218 and mounting base 217 from
a variety of angles with respect to the axis X.
[0044] FIG. 7 illustrates an example of the shaping operation 152
described in FIG. 3, and illustrated in FIG. 6, as viewed along a
different orientation. FIG. 7 illustrates a securing device 210, a
machine 212, a shaping tool 214, a raw extrusion of material 216, a
mounting base 217 and a pair of accessory rings 218. As
illustrated, the unshaped portion of the raw extrusion of material
216 is secured in the securing device 210 so that the machine 212
can use the shaping tool 214 to form the raw extrusion of material
into a different geometry that includes the pair of accessory rings
218 and the mounting base 217.
[0045] FIG. 8 illustrates an example of the forming operation 154
described in FIG. 3. FIG. 8 illustrates a securing device 210, a
machine 212, a forming tool 220, a raw extrusion of material 216, a
mounting base 217, a pair of accessory rings 218 and apertures 222
therein. The portion of unshaped raw extrusion of material 216,
illustrated in FIGS. 6 and 7, is secured in the securing device 210
along the axis X. The shaped accessory rings 218 are supported
along the mounting base 217. A forming tool 220 is secured to the
machine 212 after the shaping tool 214 was removed. The forming
tool 220 forms apertures 222 within the accessory rings 218. An
example forming tool 220 can be a boring bit operable within the
machine 212. As illustrated, the formed apertures 222 can be
concentric with each other along the axis X. The illustrated
accessory rings, 218 and apertures 222 can have geometries
resembling the accessory rings and apertures described in the
example illustrated in FIG. 3. The forming tool 220 forms the
apertures 222 along the axis X from a single direction, for example
from the distal ring 218 toward the proximal ring, as the distal
ring is distal from the unshaped portion of the raw extrusion of
material 216.
[0046] FIG. 9 illustrates an example of the forming operation 154
described in FIG. 3, and illustrated in FIG. 8, as viewed along a
different orientation. FIG. 9 illustrates a securing device 210, a
machine 212, a forming tool 220, a raw extrusion of material 216, a
mounting base 217, a pair of accessory rings 218 and apertures 222
therein. As illustrated, the unshaped portion of the raw extrusion
of material 216 is secured in the securing device 210 so that the
machine 212 can use the forming tool 220 to form the apertures 222
through the pair of accessory rings 218 secured to the mounting
base 217.
[0047] The forming operation 154 can cause springing (or elastic
springback) or distortion of the material 216 due to the friction
caused by the mechanical motion of the forming tool 220. If the
forming operation 154 is performed before the shaping operation
152, such springing or distortion of the material 216 can cause
over-stress of the material and thus misalignment of the apertures
from one accessory ring to the other. However, by performing the
forming operation 154 after the shaping operation 152, such
springing or distortion of the material 216 is reduced due to the
reduced material in the accessory rings 218, and alignment and
concentricity of the accessory rings is greatly improved.
Performing the shaping operation 152 before the forming operation
154 allows the accessory rings 218 to return to a natural free
state without stresses which would otherwise move the accessory
rings when being formed.
[0048] FIG. 10 illustrates an example of the dividing operation 156
described in FIG. 3. FIG. 10 illustrates the securing device 210,
the machine 212, the unshaped portion of the raw extrusion of
material 216, the mounting base 217, the accessory rings 218 and
formed apertures 222 defining internal passageways, a dividing tool
232, an upper cap 234 and a dividing channel 236. A dividing tool
230 can be secured to the machine 212 after the forming tool 220
(shown in FIG. 9) is removed. The dividing tool 230 generates a
dividing channel 236 into the accessory rings 218. An example
dividing tool 232 can be a cutting saw, for example with a 0.016 in
thickness, operable within the machine 212. The dividing channel
236 substantially (i.e., nearly entirely) divides each accessory
ring 218 into a lower receiver extending from the mounting base 217
and an upper cap 234. The dividing channel 236 extends
substantially through each accessory ring 218, leaving a sliver of
material undivided (or uncut) to maintain the connection between
the lower receivers and the upper caps 234. This sliver of uncut
material is further described in FIGS. 12 and 13 below. The
illustrated accessory rings, 218, lower receivers and upper caps
234 can have geometries resembling the accessory rings, lower
receivers and upper caps described in the example illustrated in
FIG. 3. In an example, the lower receiver of the accessory rings
218 and the upper caps 234 each have an equal portion of the
circumference of the formed apertures 222, such that the lower
receiver is half and the upper cap is half. The dividing tool 232
forms the dividing channel 236 that substantially divides the pair
of accessory rings 218 into lower receivers and upper caps 234
through engagement with the accessory rings along an axis that is
parallel with the axis X.
[0049] FIG. 11 illustrates an example of the dividing operation 156
described in FIG. 3 and illustrated in FIG. 10, as viewed along a
different orientation. FIG. 10 illustrates the securing device 210,
the machine 212, the unshaped portion of the raw extrusion of
material 216, the mounting base 217, the accessory rings 218 and
formed apertures 222 defining internal passageways, a dividing tool
232, an upper cap 234 and a dividing channel 236. As illustrated,
FIG. 11 shows the securing device 210, the machine 212, the
unshaped portion of the raw extrusion of material 216, the
accessory rings 218, the apertures 222, the mounting base 217, the
dividing tool 232, the upper caps 234 and the dividing channel
236.
[0050] The unshaped portion of the raw extrusion of material 216,
accessory rings 218 and mounting base 217 (FIGS. 4-11) can
thereafter be removed from securing device 210.
[0051] FIG. 12 illustrates one of the pair of accessory rings 218
on the mounting base 217, as illustrated in FIGS. 10 and 11. The
following description is also applied to the other accessory ring
218 in the pair illustrated in FIGS. 10 and 11. The illustrated
accessory ring 218 shows the aperture 222 defining the internal
passageway between an upper cap 234 and a lower receiver 237. The
dividing channel 236 substantially divides the lower receiver 237
and the upper cap 234, leaving a sliver 239 of material undivided
(or uncut) between the lower receivers and the upper caps. As
illustrated, the sliver 239 of undivided material remains
connecting the lower receiver 237 and the upper cap 234. In some
embodiments the sliver 239 has a thickness and a height in a range
from about 0.003 inch to about 0.005 inch. As contemplated, the
upper cap 234 and the lower receiver 237 remain attached to each
other by this sliver of material 239 until a user is ready to
install an accessory, for example a scope or laser sight, onto a
firearm.
[0052] FIG. 13 illustrates the accessory ring on the mounting base
217 that is shown in FIG. 12. The following description is also
applied to the other accessory ring 218 in the pair illustrated in
FIGS. 10 and 11. As illustrated, when the dividing tool 232
described in FIGS. 10 and 11 has completed the dividing process,
the upper cap 234 can be bent or folded away from the lower
receiver 237. As illustrated, the sliver 239 of material connects
the divided upper cap 234 and the lower receiver 237.
[0053] FIG. 14 illustrates the snapping operation 158 and the
buffing operation 160 described in FIG. 3. FIG. 14 illustrates the
accessory ring on the mounting base 217 that is shown in FIGS. 12
and 13. The following description is also applied to the other
accessory ring 218 in the pair illustrated in FIGS. 10 and 11. As
illustrated, the upper cap 234 can be snapped off of the lower
receiver 237, which remains secured to the mounting base 217. The
upper cap 234 can be snapped off of the lower receiver 237 manually
with a user's hands, for example through a toggling or pivoting
motion, or with a blunt object such as a piece of wood, because the
sliver 239 of the remaining undivided material is minimal and in at
least some embodiments does not require tools to be broken.
[0054] When the upper cap 234 is snapped off of the lower receiver
237, residue from the undivided sliver 239 of material remains on
the upper cap and/or the lower receiver. This remaining residue of
undivided material 239 can then be buffed out by a buffing tool,
for example a buffing tool that would be familiar to a person of
ordinary skill in the art, to render the surface smooth and free of
residue, for example as illustrated on the surface of the upper cap
234. In use, as illustrated in the examples described in FIGS. 1
and 2, the upper cap 234 and lower receiver 237 can be secured on
opposing sides of a firearm accessory, for example a scope or laser
sight, and the mounting base 217 can be secured to a firearm.
[0055] Although specific embodiments of the disclosure have been
described, numerous other modifications and alternative embodiments
are within the scope of the disclosure. For example, any of the
functionality described with respect to a particular device or
component may be performed by another device or component. Further,
while specific device characteristics have been described,
embodiments of the disclosure may relate to numerous other device
characteristics. Further, although embodiments have been described
in language specific to structural features and/or methodological
acts, it is to be understood that the disclosure is not necessarily
limited to the specific features or acts described. Rather, the
specific features and acts are disclosed as illustrative forms of
implementing the embodiments. Conditional language, such as, among
others, "can," "could," "might," or "may," unless specifically
stated otherwise, or otherwise understood within the context as
used, is generally intended to convey that certain embodiments
could include, while other embodiments may not include, certain
features, elements, and/or operations. Thus, such conditional
language is not generally intended to imply that features,
elements, and/or operations are in any way required for one or more
embodiments.
