Description
BACKGROUND OF THE INVENTION
[0001] The present disclosure relates generally to firearm
accessories and more particularly, pertains to a heatshield
mounting arrangement provided for a barrel of a firearm or
weapon.
[0002] It is well known to those skilled in the art that rapid-fire
weapons, such as semi-automatic or automatic rifles and shotguns
are characterized by the heating of their metal barrels to
relatively high temperatures, often in excess of 600 degrees
Fahrenheit. At such intense temperatures, the barrels cannot be
comfortably or safely handled by the shooter of the weapon. Various
expedients, typically in the form of heatshield assemblies, have
been resorted to in the past in an attempt to protect the hands of
the person firing the weapon from harmful contact with the
excessively hot barrel.
[0003] Certain known heatshield assemblies typically include a
curved, perforated metallic body having, front and rear tabs,
clamps, flanges or other retaining structures which are integrally
formed on the body. These integral retaining structures are bent,
clamped and secured with additional fasteners to the metal barrel
to mount the heatshield assembly along substantially the entire
length of the barrel. Such known heatshield assemblies have been
designed to allow dissipation of heat to protect the shooter's
hands during the rapid discharging of the firearm. Unfortunately,
installation and use of these currently available heatshield
assemblies results in sliding metal-to-metal contact between the
heatshield body and the barrel causing possible damage to the
barrel which is undesirable.
[0004] Accordingly, there is a need to provide a heatshield
mounting arrangement in which a heatshield body is secured to the
firearm in a suspended, floating relationship over the barrel so as
to prevent any direct metal-to-metal contact between the heatshield
body and the barrel and eliminate any scratching or damage to the
barrel. There is an additional need to provide a firearm heatshield
having a forend mounting arrangement which prevents movement of the
heatshield body relative to the barrel dining use.
SUMMARY OF THE INVENTION
[0005] The present disclosure relates to a heatshield mounting
arrangement adapted to be used on a firearm having a receiver, a
barrel extending forwardly of the receiver and a magazine rube

includes a set of spaced apart U-shaped brackets. Each of the
U-shaped brackets has a bottom wall joined to a lower wall of the
forend body, and a pair of spaced apart sidewalls extending from
the bottom wall. A first set of fasteners is provided to secure the
bottom walls of the U-shaped brackets to the lower wall of the
forend body. The sidewalls of the U-shaped brackets have upper ends
provided with throughholes in communication with the recesses
formed in the upper ends of the forend body. A second set of
fasteners is provided to secure the upper ends of the U-shaped
brackets with the mounting feet of the heatshield body. Outer
surfaces of the U-shaped brackets are engaged against an inner
surface of the forend body.
[0007] The present disclosure also relates to a forend assembly
adapted to be used in a heatshield mounting arrangement for
mounting a heatshield over a barrel of a firearm. The forend
assembly includes an elongated U-shaped forend body having a lower
wall and a pair of spaced apart sidewalls rising from the lower
wall, and provided with upper ends adapted to be secured to the
heatshield. A U-shaped bracket arrangement is received and retained
within the forend body. The U-shaped bracket arrangement has a
lower attachment area secured to the lower wall of the forend body,
and an upper attachment area aligned with the upper ends of the
forend body and adapted to be connected to the heatshield.
[0008] Upper ends of the forend body extend inwardly of the
sidewalls. A first set of fasteners is provided to secure the lower
attachment area of the U-shaped bracket arrangement to the lower
wall of the forend body. A second set of fasteners is received in
the upper attachment area of the U-shaped bracket arrangement and
is adapted to secure the heatshield thereto. The U-shaped bracket
arrangement is formed by a set of spaced apart U-shaped brackets
having outer surfaces which are engaged against an inner surface of
the forend body.
[0009] The present disclosure further relates to a mounting
arrangement for a firearm having a receiver, a barrel extending
forwardly from the receiver and a magazine tube extending forwardly
from the receiver beneath the barrel. The mounting arrangement
includes an elongated heatshield body having a set of mounting feet
provided thereon. A forend assembly includes a U-shaped forend body
and a U-shaped bracket assembly received and retained within the
forend body for receiving the magazine tube and connecting the
mounting feet to the forend assembly such that an entire length of
the heatshield body is mounted in a continuous spaced floating
relationship over the barrel to prevent any contact between the

front end of the barrel 16.
[0022] Referring now to FIGS. 2, 6 and 7, the heatshield 18 has a
heatshield body 54 which is constructed of an elongated, perforated
and inverted shell which is preferably comprised of anodized
aluminum or another suitable metal material. The heatshield body 54
is configured with a front end 56 and a rear end 58, and is
integrally formed with an arcuate upper wall 60 and a pair of
opposed sidewalls 62, 64 depending from the upper wall 60. The
sidewalls 62, 64 are formed along the length of the heatshield body
54 with a series of spaced vent openings 66 which extend laterally
outwardly and downwardly from the upper wall 60 to permit airflow
through the heatshield 18. Bottom edges of the sidewalls 62, 64 are
provided with a retaining structure embodied in a first pair of
outwardly projecting mounting feet 68 located adjacent the rear end
58, and a second pair of outwardly projecting mounting feet 70
located in the central portion of the heatshield body 54.
[0023] As best seen in FIGS. 3 and 7, forend assembly 28 includes
an elongated U-shaped forend body 72, and a bracket arrangement
formed by a pair of spaced apart U-shaped brackets 74, 76 designed
to be received and retained within the forend body 72. The thread
body 72 is typically constructed of a polymer material, and has a
length which is shorter than a length of the heatshield body 54.
The forend body 72 is integrally formed with an arcuate lower wall
78 and a pair of spaced apart sidewalls 80, 82 having respective
spaced upper ends 84. 86 which extend inwardly of the sidewalls 80,
82 and define an open top. As best seen in FIG. 2, the upper ends
84, 86 are formed with a first pair of recesses 88 located near a
rear end 90 of the forend body 72, and a second pair of recesses 92
spaced towards a front end 94. The recesses 88, 92 are configured
to receive the mounting feet 68, 70 on the heatshield body 54, and
to be supported on lower apertured walls 87 of the recesses 88, 92.
A portion of the lower wall 78 is preferably provided with a
non-slip textured coating 96 for improving the gripping ability of
the forend body 72. The lower wall 78 and coating 96 are formed
therethrough with a first pair of apertures 98 adjacent the rear
end 90 of forend body 72, and a second pair of apertures 100 spaced
forwardly near a front end 94 of the forend body 72.
[0024] Each of the U-shaped brackets 74, 76 has an identical
construction, and includes a bottom wall 102 joining a pair of
opposed sidewalls 104, 106. Outer surfaces of the brackets 74, 76
are sized and shaped to engage the inner surface of the forend body
72. Each bottom wall 102 is formed with a pair of spaced apart
holes 108 which are designed to be aligned with the apertures 98,
100 provided in the forend body 72. Each of the sidewalls 104, 106
has upper ends 110, 112 formed with respective throughholes 114,
116 (FIG. 6) which are alignable with suitable apertures provided
in the mounting feet 68, 70 on the heatshield body 54 as well as
with the recesses 88, 92 of the forend body 72.
[0025] A first set of threaded fasteners 118 is designed to be
passed through the holes 108 in the bottom walls 102 of the
U-shaped brackets 74, 76 and to be screwthreaded into the apertures
98, 100 formed through the lower wall 78 and coating 96 of the
forend body 72. A second set of threaded fasteners 120 is designed
to be passed through apertures in the mounting feet 68, 70 on the
heatshield body 54 when the mounting feet 68, 70 are received in
the recesses 88, 92 of the forend body 72, and to be screwthreaded
into the throughholes 114. 116 of the brackets 74, 76 once the
brackets 74, 76 are secured to the lower wall 78 of the forend body
72.
[0026] When it is desired to mount the heatshield body 54 on the
shotgun 10, the U-shaped brackets 74, 76 are slidably received
within the forend body 72 such that the bracket holes 108 are
aligned with the forend body apertures 98, 100. The brackets 74, 76
are retained within the forend body 72 by turning the fasteners 118
into the apertures 98, 100 formed through the lower wall 78. The
forend assembly 28 is then moved upwardly and positioned around the
barrel collar 22 and the rear portion of the magazine tube 24, and
the heatshield body 54 is positioned over the rear portion of the
barrel 16 so that the mounting feet 68, 70 are received in the
recesses 88, 92 at the upper end of the forend body 72. Thereafter,
the fasteners 120 are passed through apertures in the mounting feet
68, 70 and threaded into the throughholes 114, 116 at the upper
ends 110, 112 of the brackets 74, 76 secured to the lower wall 78
of the forend body 72.
[0027] With this assembly, the lower portion of the magazine tube
24 is engaged by the bottom walls 102 of the U-shaped brackets 74,
76. The sidewalls 104, 106 of the brackets 74, 76 extend upwardly
spaced from the magazine tube 24, and are engaged with the inner
surface of the sidewalls 80, 82 of the forend body 72. Upper ends
84, 86 of the forend body 72 lie adjacent lower portions of the
barrel 16. The forend body 72 is designed to cover or shield the
rear portion of the magazine tube 24, and to shield a lower rear
portion of the barrel 16 as seen in FIG. 2. The entire length of
the heatshield body 54 is held continuously spaced from and
suspended in floating relationship over the barrel 16. The
heatshield body 54 is secured to the top of the forend body 72 so
as to prevent any movement of the heatshield body 54 relative to
the barrel 16 during use of the shotgun 10. As seen in FIG. 5, the
rear end 90 of the forend body 72 lies adjacent a front edge of the
receiver 14, and the front end 94 of the forend body 72 lies
adjacent a rear end of the mounting rail device 30.
[0028] In accordance with the present disclosure, the heatshield
mounting arrangement 12 is defined by the heatshield body 54 having
a retaining structure 68, 70 and the forend assembly 28 including
the forend body 72 and the bracket arrangement 74, 76 which
connects the retaining structure 68, 70 of the heatshield body 54
to the top end of the forend body 72. The heatshield mounting
arrangement functions to mount the heatshield body 54 along an
entire length thereof in a continuous spaced apart, floating
relationship over the barrel 16. That is, the mounting arrangement
12 creates a continuous unobstructed space 122 between the outer
surface of the barrel 16 and the inner surface of the heatshield
body 54 over the entire length of the heatshield body 54 so that
contact between the barrel 16 and the heatshield 18 is prevented.
Such a design ensures that the metal barrel 16 will not be
scratched or damaged, and that there is no direct transfer of heat
from the barrel 16 to the heatshield 18 so that heat is dissipated
and cooler ambient air is communicated through the vent openings 66
of the floating heatshield 18.
[0029] Various alternatives are contemplated as being within the
scope of the following claims particularly pointing out and
distinctly claiming the subject matter regarded as the
invention.
