Claims
I claim:
1. The multiple rail adapter as recited in claim 1, requires no
modification to rifle or carbine upon which it will be
installed.
2. The multiple rail adapter as recited in claim 1, comprises a
body and clamping bar made of lightweight aluminum alloy extrusion,
clamping bolts and clamping nuts made of steel.
3. The mounting rail adapter provides two "Picatinny" type mounting
rails for the installation of multiple sighting devices. The
primary accessory rail is located above the rifle or carbine
receiver rail and has a centerline plane that runs parallel with a
longitudinal plane of the rifle or carbine that said adapter would
be installed upon. A secondary accessory rail is positioned with a
centerline plane pivoted in a 45-degree counterclockwise direction
when viewing the weapon with the muzzle pointing away from the
weapon holder and with same said centerline plane running

BACKGROUND OF THE INVENTION
[0002] 1. Field of Invention
[0003] The present invention relates to mounting adapters for
rifles. More specifically, the present invention relates to an
adapter mount for supporting multiple sighting devices
simultaneously on the "Flat Top" versions of the M-16 and AR-15
family of rifle and carbines.
[0004] 2. Discussion of Background
[0005] The increasing need for sophisticated and multifunctional
firearms, in particular the M-16 and AR-15 family of firearms, has
created a requirement that the firearms be able to accommodate
various sighting accessories such as infrared and night vision
scopes, laser spotters and similar devices. In the past, the Art
has developed systems that required changes and modification to the
firearms upon which they are to be installed. The following
summarizes the state of the current art.
[0006] U.S. Pat. No. 5,590,484 requires the removal of the original
handguards, barrel nut, gas block and the carrying handle is
machined off to provide mounting of a multiple rail adapter.
[0007] U.S. Pat. No. 5,826,363 requires the removal of the original
handguards to provide mounting of a rail adapter system.
[0008] U.S. Pat. No. 6,295,754 relates to a telescopic sight with a
single integral mounting feature to mount auxiliary equipment on
the telescopic sight.
[0009] U.S. Pat. No. 5,941,489 is a T-rail that can be mounted to a
standard mounting rail on a weapon. The T-rail has a single upper
Picatinny rail that extends along the top of the T-rail and an
extension that extends perpendicularly therefrom.
SUMMARY OF THE INVENTION
[0010] The present invention is a multiple rail adapter utilizing
the "Picatinny" rail system for attaching to the M16 and AR15 type
rifle or carbine receiver. The multiple rail adapter provides two
"Picatinny" type-mounting rails for support of accessory devices
that enhance the operational capabilities of the weapon. The
multiple rail adapter consists of a primary accessory rail and a
secondary accessory rail.
[0011] The primary accessory rail is located above the rifle or
carbine receiver rail and has a centerline plane that runs parallel
with a longitudinal plane of the rifle or carbine that said adapter
would be installed upon.
[0012] A secondary accessory rail with a centerline plane pivoted
in a 45-degree counterclockwise direction when viewing the weapon
with the muzzle pointing away from the weapon holder and with same
said centerline plane running longitudinally along centerline plane
of rifle or carbine.
[0013] Installation of the multiple rail adapter is accomplished by
aligning the positioning groove of the multiple rail adapter with
the right side protrusion of the "Picatinny" rail of the weapon.
The multiple rail adapter is then pivoted in the direction of the
weapon receiver until the bottom of the multiple rail adapter
contacts the top of the "Pictanny" rail of the weapon.
[0014] The mounting rail adapter is positioned fore or aft to a
point that best suits the accessory sighting device and weapon
holder and the clamping bolts are positioned directly above the
recoil grooves on the weapon provided by the "Pictanny rail".
[0015] Locking the multiple rail adapter to the weapon is
accomplished by rotating the clamping nuts clockwise, when viewed
from right side, forcing the clamping bar inward until the surfaces
on the clamping bar contact the surface on the "Pictanny" rail of
the weapon and contact surface of the adapter. This creates a
clamping action thus providing a stable and solid assembly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0029] With reference to FIG. 1 of the drawings, the present
invention illustrates a multiple rail adapter 1 mounted to a "flat
top" carbine 6 of the M16 & AR-15 family of weapons utilizing
the "Picatinny" rail system.
[0030] As shown in FIG. 12, the multiple rail adapter 1 provides a
positioning groove 7 and a clamping groove 8 shown in FIG. 10.
[0031] As shown in FIGS. 8, 10 & 12, the two "Picatinny" type
mounting rails 13 & 14 support accessory devices that enhance
the operational capabilities of the weapon. The mounting rail 13 is
the primary accessory rail and the mounting rail 14 is the
secondary accessory rail.
[0032] With particular reference to FIG. 12, installation of the
multiple rail adapter 1 is accomplished by aligning the positioning
groove 7 with the left side protrusion of the "Picatinny" rail 9 of
the weapon 6.
[0033] The mounting rail adapter 1 is positioned fore or aft to a
point that best suits the accessory sighting device and weapon
holder and the locking bolts 5 are positioned directly above the
recoil grooves 11 on the weapon 6 provided by the "Pictanny" rail
9.
[0034] Per FIG. 10, locking the multiple rail adapter 1 to the
weapon 6 is accomplished by rotating the locking nuts 4 clockwise,
when viewed from right side, causing the clamping bar 3 to travel
inward creating a interference fit with the "Pictanny" rail 9 of
the weapon. This interference fit provides a stable and solid
assembly.
[0035] It will be apparent to those skilled in the art that changes
and modifications can be made to the preferred embodiment herein
described without departing from the spirit and scope of the
present invention as defined by the appended claims.
