Curved Anti-Ballistic Glass Armor with Argon Chamber for Car Windows and Manufacturing Method

Abstract

The present invention belongs to the field of shielding mechanics for personal protective equipment and more specifically relates to the external shielding of a transparent glass or armor curved and laminated on its periphery, which has an argon chamber for automobile windows that does not requires modification of door or window frames; since it proposes a new solution with a reinforced flange that is established in the armor and not in the frame of the vehicle, made up of a perimeter steel flange, glass of different sizes, reinforcing polycarbonates and an argon chamber that makes it light, thin, which does not fog up due to temperature changes and blocks external bullet impacts but is permissive to the passage of bullets towards the outside of the vehicle due to internal impact.

DETAILED DESCRIPTION OF THE INVENTION

[0017] The antiballistic curved glass armor (10) comprises an external section (30) with two glass sheets (16), (17) of equal size, laminated with a ionoplast layer (28) on its external perimeter section (18) and joined to a smaller internal section (31) that has two polycarbonate sheets (20), (21) of equal size, laminated with a polyurethane layer (32) in its internal perimeter section (33). The union between the external section (30) and the internal section (31) forms an argon chamber (11) and at the top there is a flange (12) formed by the difference in size between the glass sheets (16), (17) of the external section (30) and the polycarbonate sheets (20), (21) of the internal section (31).

[0018] The flange (12) compensates for the weak edge of traditional 8 mm armored glass and withstands the impacts of projectiles fired from firearms from the outside of the vehicle and is a lightweight solution for attachment to a traditional vehicle window. For the perimeter reinforcement, the entire perimeter section (34) including the flange (12) is laminated with a steel metal strip (13) from 1.5 mm to 2 mm thick; so that the flange (12) laminated with steel metal strip (13) enters the cavity (15) of the original frames (14) of the vehicle without the need to make extensions to the original frame (14).

[0019] The antiballistic curved glass armor (10) is composed of a perimeter section (34) formed by the external perimeter section (18) and the internal perimeter section (33) where the lamination of the sheets is carried out together: lamination of the external glass sheet (16), lamination of the internal glass sheet (17), lamination of the external polycarbonate sheet (20) and lamination of the smaller internal polycarbonate sheet (21), without laminating the entire surface of the layers, but only in said perimeter section (34). This perimeter section (34) is painted with the traditional black color and has adhesive (25) to give an external appearance that simulates a common vehicle window glass.

[0020] The first external glass sheet (16) is joined to the internal glass sheet (17) with a ionoplast layer (28) in between them and makes up the largest area of the antiballistic curved glass armor (10); where the internal face (26) of the first external glass sheet (16) is laminated with the external face of the ionoplast layer (28) on the external perimeter section (18), and in turn, the external face (27) The internal glass sheet (17) is laminated to the inner face of the ionoplast layer (28) on the external perimeter section (18).

[0021] The first external polycarbonate sheet (20) is joined to the internal polycarbonate sheet (21) with a polyurethane layer (32) in the middle of them and makes up the smaller area of the curved anti-ballistic glass armor (10); where the internal face (35) of the external polycarbonate sheet (20) is laminated with the external face of the polyurethane layer (32) in the internal perimeter section (33), and in turn, the external face (36) of the internal polycarbonate sheet (21) is laminated to the inner face of the polyurethane layer layer (32) in the inner perimeter section (33).

[0022] The first external glass sheet (16) joined to the internal glass sheet (17) has the same curved path and the same size as an original frame (14). The flange (12) laminated with metal strip (13) that enters the cavity (15) of the original frames (14) of a vehicle is formed by a projection (24), whose projection (24) protrudes a defined distance from the edge of the facing glass sheets (16) and (17) and the edge of smaller facing sheets (20) and (21) made of thermoplastic material; where the facing glass sheets (16) and (17) are distanced with double-sided tape (38) from the facing polycarbonate sheets (20) and (21), but joined with urethane (23) in their internal perimeter section (33).

[0023] Said internal perimeter section (33) has a perforation region (37) through which the argon gas is introduced into the argon chamber (11) at the time of its manufacture and a perforation region (39) through which the air is expelled. the argon chamber (11); where said perforation regions (37), (39) are sealed when the argon chamber (11) only houses argon gas.

[0024] So that the antiballistic curved glass armor (10) on its external part has the flange (12) laminated with a metal strip (13), on the periphery there is the laminate of the layers and the chamber seal with urethane (27), and in the internal part is the argon chamber (11).

[0025] The first external polycarbonate sheet (20) and the second internal polycarbonate sheet (21) are laminated in their internal perimeter section (33) under vacuum; where the polycarbonate sheets (20) and (21) that form the internal wall of the argon chamber have a smaller perimeter between 1 and 3 cm than the perimeter of the glass sheets (16) and (1) that form the wall external of the argon chamber, forming the projection (24) of the flange (12) laminated with steel metal strip (13).

[0026] The manufacturing process of the antiballistic curved glass armor (10) with flange allows the following stages: [0027] Cut glass sheet into a first external glass sheet (16) and a second internal glass sheet (17) or into more sections of external glass sheet (16) traced with the vehicle template to form an external section (30) of larger size of an anti-ballistic curved glass armor (10). [0028] Polish and powder the external glass sheets (16) and internal glass sheets (17). [0029] Bake at 630 degrees Celsius for curving. [0030] Paint the external perimeter section (18). [0031] Laminate these two or more glass sheets (16), (17) according to the level of protection required with ionoplast layer (28) in its external perimeter section (18). [0032] Cover with a vacuum bag and insert into autoclave for lamination at 135 degrees Celsius. [0033] Cool to room temperature between 8 degrees Celsius to 35 degrees Celsius and polish [0034] Cut polycarbonate into a first external polycarbonate sheet (20) and a second internal polycarbonate sheet (21) to form a smaller internal section (31) with a smaller perimeter between 1 and 3 cm than the perimeter of the glass sheets (16), (17), forming the projection (24). [0035] Laminate between the first external polycarbonate sheet (20) and the second internal polycarbonate sheet (21) with a polyurethane layer (32) in between them, laminating the internal perimeter section (33), [0036] Cover with a vacuum bag and insert into autoclave for lamination at 125 degrees Celsius. [0037] Join the laminated curved glass of the external glass sheet (16) and the internal glass sheet (17) with the external polycarbonate sheet (20) and the internal polycarbonate sheet (21) using double-sided tape (38) as a separator to form the argon chamber (11) leaving an upper flange (12) as an offset. [0038] Seal the internal perimeter section (33) with urethane (23). [0039] Drill a hole in the drilling region (37) and introduce argon. [0040] Drill a hole in the perforation region (39) and expel air by suction from the argon chamber (11). [0041] Protect the edge of the glass perimeter with metal strip (13) and adhesive (25). [0042] Seal the entire internal perimeter section (33) and the external perimeter section (18) with urethane (23).

[0043] An invention is presented with a new way to solve the problem of known curves that protects from external impacts to prevent bullets from entering the interior of the vehicle, but at the same time allows internal impacts for 9 mm bullets to exit the vehicle to defend against external aggressor. In addition, the solution prevents the laminated layers from losing transparency and delamination because the lamination is carried out on the periphery and not on the entire surface. Finally, visibility in the windows is preserved despite changes in ambient temperature due to freezing, since the melting point of argon is 189.4 C. and this solution was not known to be incorporated in a steel armor. Anti-ballistic curved glass.
