Description

WEAPON SILENCER HEAT INSULATING SHELL AND

TRANSPORTATION SOLUTION

FIELD OF THE INVENTION

The subject of the invention is soldiers, authorities and other users who use a handgun that needs to be fired several times with a silencer attached. The silencer referred to in this application is mainly for serial fire and one-shot automatic weapons in military use.

BACKGROUND OF THE INVENTION

A gun silencer silences the sound of a gun shot. It slows down the speed of the hot, overpressured gunpowder gases released from the barrel of the gun after the bullet and reduces the resulting noise. Hot gunpowder gases cause the muffler to heat up. The most common materials used are aluminum, titanium and steel. When firing several shots, the silencer gets very hot and at some point the heat approaches the melting point so much that the structure of the silencer is damaged. This warming also causes other problems, such as the intensification of the heat trace exposed to the enemy's thermal camera, and the thermal flickering of the air over the muffler. Thermal flickering hinders aiming the weapon because the sights are usually located on top of the handgun. Firing multiple shots quickly makes the silencer dangerously hot for the user and their equipment.

The solution to this problem has been various covers made of heat-resistant fabric, which insulate the outside of the damper and thus slow down

N of heat conduction from the damper's outer shell to the environment. Another solution is to do

N 20 hard shell that leaves an air space between the silencer and the shell. In this case, the air gets = to cool the silencer and does not cause much more warming. This type of protection z also does not heat up as quickly as a fabric one with a solid connection. a

N The problem with handling a hot muffler is that the muffler may be = several hundreds of degrees Celsius hot. In this case, even the fabric cover may be flammable

N 25 for hand. Removing and transporting the damper can be challenging.

Silencer vibration shields and heat shields are produced by several manufacturers, and one well-known product in the field is Magpull Industries Corp's Suppressor Cover, which has a patent

USD833565S1. In this style of cover, air can circulate freely between the silencer and the shell. However, such a cover does not consider quick and easy removal of the cover from the muffler or thermal insulation in terms of handling and transporting the muffler. It also doesn't have any designed feature for carrying the muffler in gear.

The insulation built into the mufflers is handled by the Gladius Suppressor

Company, LLC in patent US10480886(B2). The patent also mentions a loose muffler protective cover, but does not mention quick removal of the protective cover or transporting the muffler using the protective cover. There are plenty of muffler covers on the market made of different fabrics and different ways of wear, for example made of silicone. Some of them are intended only for single-shot weapons to prevent air ripple and not much attention has been paid to the silencer's abundant heating. A very common fabric structure on the market is represented by Dale

Avery Poling Patent US20120167435A1. Advanced solutions are represented by Advanced

Innovation and Manufacturing, Inc. US20140059913A1.

The difference between the removable heat and transport cover and other muffler protection and heat covers is that it enables the hot muffler to be removed, attached or tightened without special arrangements such as changing gloves or rags. In addition to this, it allows the muffler to be carried in combat gear while hot.

PURPOSE OF THE INVENTION

O Insulated quick-release muffler shell solves the problem in a way that it does

N muffler can be removed with a quick release or screws. At the same time it

N allows a hot silencer to be carried in battle gear without z 25 damaging other gear or causing burns to the user. a

= DESCRIPTION OF THE INVENTION

OF

The purpose of the invention is to reduce the thermal excitation of the muffler and make the muffler safe to handle and transport even when hot without separate handling equipment. The problem has been solved with a mechanical holder, which enables the muffler and the muffler's protective shell to be handled separately. There is an attachment point in the shell, to which various of the most common quick-attachment solutions for combat equipment can be attached with screws or otherwise. As an example, a spring steel belt loop.

Thermal insulation has been solved by using as few heat-conducting and heat-resistant materials as possible, such as silicone, ceramics and carbon fiber. There is a space between the muffler and the protective cover that prevents heat from being conducted from the muffler to the protective cover. In addition to this, space has been reserved inside the protective shell for heat-resistant thermal insulation such as airgel. The insulation may need to be replaced. Such a high-performance thermal insulation such as airgel insulates heat better than other existing insulation materials and makes a clear difference in the heat generation of this shell compared to other thermal shields. The structure allows that the muffler can still cool down when the air circulates and the thermal insulation material can be changed.

The muffler rests on a cone-shaped front piece, which has grooves that also allow air to flow through the hole in front of the protective cover. The shape of the front piece allows — the same = piece — to be used in mufflers with different — diameters. The back part consists of flexible claws, which can be three or more. Four of them are presented in this application. The claws hold the protective shell in place with the cone of the front piece. When squeezing the back of the protective cover, the claws press against the muffler or its possible locking ring at the back and enable rotation. In an alternative method of attachment, the muffler has threads on which the protective cover wraps. Unintentional opening due to gun vibration

The twisting of N is prevented by the spring of the shell, which presses into the muffler for this purpose

N 25 in a groove or with two oppositely placed magnets that attract each other. Such a structure leaves room for handling the locking piece 9 of the silencers on the locking piece.

DETAILED DESCRIPTION OF THE INVENTION

The invention is characterized by the fact that the weapon's silencer (3) fits inside it (1) and rests on the front end of the cone-shaped grooved body (5). The claw (10) of the back piece (8) of the protective cover (1) can move outwards from the silencer (3) when the protective cover (l) is put on or taken off the muffler (3) due to its structure and the cuts between the claws (10), so that when the user pulls or pushes the protective cover (l) ) on the muffler (3), the claw (10) gives way to the front edge of the muffler (3) or falls over the rear edge, preventing the muffler from moving forward without external force. From the cuts (4) between the nails (10), air can move between the protective cover and the muffler, also from the back of the protective cover (1). When pressing, from the back of the protective cover (1) at the rear part (8), the fixing nails bend inwards and catch the back of the muffler (3) or its = possible back part — the fixing ring (7). In this case, the muffler(3) or — retaining ring(7) = it is = possible to — rotate the muffler(3) to detach it from the weapon(9).

OF

N A special characteristic feature is the cone-shaped grooved front piece (5) whose front

S in the grooves in the back direction, the air of the intermediate space (4) can move through the front end of the protective shell and out

S between the protective cover (1) and the muffler (3). The cone-shaped front piece (5) centers

E 25 with its symmetrical wedge-like shape around the front end 0 of the tubular muffler (3) and prevents the protective shell from moving backwards along the muffler.

S The front part (2,5) and the back part (8) of the protective cover are attached to the frame tube (14).

The body tube is a heat-resistant rigid material such as steel, and it can have lightening and cooling holes. The other parts of the protective cover (1) are attached to the frame tube (14)

about. There is heat insulation around the body tube (14) and the body tube (14) prevents the heat insulation (13) from directly touching the muffler (3) shell. The thermal insulation (13) slows down the heat of the muffler (3) caused by the firing of the air (4) heated by the heat through the body tube by radiating and conducting the transfer of the transferred heat to the outer shell of the protective shell 5 (6). In this way, the heating of the protective shell (1) due to the firing of the outer shell to a dangerous level for the user slows down. There can also be thermal insulation (16) on the front side of the front piece (5), which is held in place by a cover plate (17) embedded in the front piece (5).

An alternative locking solution (2) between the muffler (3) and the protective cover (1) is the threads (22) made in the front of the muffler (3) into which the threads (21) of the protective cover (1) can be threaded when it is threaded over the muffler (3). At the end of the rotation, the spring (19) of the front part (17) presses into the cut (20) made for this purpose in the muffler and causes friction that prevents the protective cover (1) from rotating in the threads (22) of the muffler (3) without the user's force. Another option is to ensure the durability of the screw fastening (21, 22) is that at the end of the winding, the magnets (23, 24) that attract each other meet and attract each other with a force that prevents the protective cover (1) from winding in the threads of the muffler (3) (22) without the user's force.

In the frame tube (14) or front piece (5) or rear piece (8) of the protective cover (1), there is a solid straight-surfaced piece (11) that protrudes only slightly from the profile of the protective cover (1) and has holes for screwing in a suitable fastening piece.
