Description

BACKGROUND OF THE INVENTION

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.
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.
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.
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.

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.
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.
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.
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.
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.
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.
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.
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.
