DETAILED DESCRIPTION OF THE INVENTION
[0016] The following detailed description is of the best currently
contemplated modes of carrying out exemplary embodiments of the
invention. The description is not to be taken in a limiting sense,
but is made merely for the purpose of illustrating the general
principles of the invention, since the scope of the invention is
best defined by the appended claims.
[0017] The present invention may include a Picatinny rail mount
fixture having a crosscut sliding dovetail joint to accept pistol
sights. The fixture when attached to a Picatinny rail system
facilitates the fitting of commonly available dovetail pistol
sights to the firearm. These pistol sights are commonly sold in
pairs and the fixtures may likewise be sold in pairs. This provides
for an enhanced close quarter battle sighting on long guns. In
certain embodiments, the present invention may facilitate the
fitting or mounting of sliding dovetail pistol sights on a
MIL-STD-1913 Picatinny rail system.
[0018] The rear sight mount fixture may facilitate the attachment
or installation of a common production rear sliding dovetail pistol
sight into a fixture providing attachment to a MIL-STD-1913
Picatinny rail system and provides for left or right adjustment of
the rear sight. The front sight mount fixture may facilitate the
attachment or installation of an accompanying common production
front sliding dovetail pistol sight into a fixture providing
attachment to a MIL-STD-1913 Picatinny rail system and provides for
elevation adjustment of the front sight. The rear and front sight
mount fixtures for MIL-STD-1913 Picatinny rail systems combine to
provide for a clear, accurate, and fully adjustable sighting
system.
[0019] Referring now to FIGS. 1 through 7, the present invention
includes a sight mounting adapter 10. The sight mounting adapter 10
may include a rear sight block 14 and a front sight block 12. Each
of the rear sight block 14 and the front sight block 12 include a
top end 42, a bottom end 44 a first side 46, a second side 48, a
front end 50, and a back end 52. The top ends 42 include an upper
dovetail channel 26 and the bottom ends 44 include a lower tactical
rail 27, such as a 90 degree combined angle channel. The upper
dovetail channel 26 of the rear sight block 14 is formed to receive
a rear dovetail sight 14a. The upper dovetail channel 26 of the
front sight block 12 is formed to receive a front dovetail sight
12a. The lower tactical rail channels 27 of the rear sight block 14
and the front sight block 12 are formed to releasably secure to a
tactical rail 20, such as a Picatinny rail.
[0020] In certain embodiments, the lower tactical rail channels 27
of the rear sight block 14 and the front sight block 12 each
include a cross bore 28 running perpendicular to the lower tactical
rail channel 27. A rail mount tension screw 16 may fit through the
cross bore 28. The lower tactical rail channel 27 may be attached
to a tactical rail 20 by fitting the lower tactical rail channels
27 over the tactical rail 20, and then running the rail mount
tension screw 16 through the cross bore 28 on a first side 46 of
the lower tactical rail channel 27. The threaded end of the rail
mount tension screw 16 may screw into a threaded nut 32 within a
hexagonal countersink 30 located within the cross bore on the
second side 48 of the lower tactical rail channel 27. Tightening
the rail mount tension screw 16 into the threaded nut 32 tightens
the lower tactical rail channel 27 onto the tactical rail 20.
[0021] In certain embodiments, the upper dovetail channel 26 may
run substantially perpendicular to the lower tactical rail channel
27 for each of the rear sight block 14 and the front sight block
12. In such embodiments, the upper dovetail channel 26 may run from
the first side 46 to second side 48 of the sight blocks 12, 14, and
the lower tactical rail channel 27 may run from the front end 50 to
the back end 52 of the sight blocks 12, 14. Therefore, the dovetail
sights 12a, 14a may be adjusted from the first side 46 to the
second side 48 within the upper dovetail channels 26. The user can
mount the sights via the "Drifting Method" using a brass punch and
hammer or the "Press fit" method using a dovetail pistol sight
mounting tool. Further, at least one of the rear sight block 14 and
the front sight block 12 may be adjustable in height. As
illustrated in FIG. 1, both sight blocks 14 may be adjustable in
height. Therefore, the sight blocks 12, 14 and the dovetail sights
12a, 14a may easily be adjusted for accuracy.
[0022] In certain embodiments, when at least one of the sight
blocks 12, 14 are adjustable in height, at least one of the sight
blocks 12, 14 may have a detachable base 34 at the bottom end 44.
The lower tactical rail channel 27 may be part of the detachable
base 34. The detachable base 34 may include at least one clearance
hole 38. The sight blocks 12, 14 may include at least one threaded
hole 40 aligned with the at least one clearance hole 38. At least
one screw 36 is formed to fit through the at least one clearance
hole 38 and thread into the at least one threaded hole 40, thereby
securing the detachable base 34 to the at least one of the rear
sight block 14 and the front sight block 12.
[0023] To adjust the height of the sight blocks 12, 14, at least
one spacer plate 17 may be placed in between the detachable base 34
and the sight block 12, 14. For example, a plurality of spacer
plates 17 may be placed in between the detachable base 34 and the
sight block 12, 14. The spacer plates 17 may each include at least
one clearance hole 38 aligned with the at least one clearance hole
38 of the detachable base 34 and the at least one threaded hole 40.
Therefore, the screw 36 may fit through the clearance hole 38 of
the base 34 and at least one spacer plates 17 and screw into the
sight block 12, 14.
[0024] As illustrated in the FIGS. 2 through 7, one of the sight
blocks 12, 14 may be adjustable in height, such as the rear sight
block 14. In certain embodiments, the detachable base 34 and the
plurality of spacer plates 17 may each include two clearance holes
38. The rear sight block 14 may also include two threaded holes 40.
Two screws 36 may fit through the two clearances holes 38 of the
detachable base 34 and the plates 17 and screw into the threaded
holes 40 of the rear sight block 14. The height of the sight blocks
12, 14 may be adjusted based on how many spacer plates 17 are in
disposed in between the detachable base 34 and the front sight
block 12.
[0025] As illustrated in FIG. 1, the sight mounting adapter 10 may
be used with a rifle 22 having a scope 24. The sight blocks 12, 14
of the sight mounting adapter 10 may be mounted to a side mounted
tactical rail 20. The rear sight block 14 may be attached to the
rearward section of the side mounted tactical rail 20, and the
front sight block 12 is attached to the forward section of the side
mounted tactical rail 20. The side mounted tactical rail 20 may be
mounted to the rifle 22 by clamping attachments 18. The clamping
attachments 18 may attach to the tactical rail 20 or the handle of
the rifle 22. The sight blocks 12, 14 including the sights 12a, 14a
may be attached to the rifle 22 via the side mounting tactical rail
20 and thereby may be oriented to the side of the scope 24.
Therefore, a user may use the sights 12a, 14a during short range
combat, and may use the scope 24 during longer range combat.
[0026] A method of making the present invention may include the
following. The sight blocks may be manufactured from aluminum alloy
blocks 2.0'' high.times.1.2'' wide.times.0.81'' thick and are
milled on a CNC Boring Milling Machine or on a manual horizontal
milling machine. The MIL-STD-1913 slot may be cut with a custom
Double Chamfer Cutting tool sized to fit the 0.835 inch width
MIL-STD-1913 slot profile and provides for the 90 degree combined
angle for the slot. The dovetail slot profile is cut with a
standard dovetail mill cutting tool perpendicular to the bore of
the firearm on the top area of the fixtures and are sized to fit
the standard dovetail slot widths of 0.300 inch and 0.330 inch, and
