INVENTOR.
HENRY RITTER ATTORNEYS.
Patented Jan. 11, 1966 3,228,361 LIGHTWEIGHT SANDWICH ARMOR PLATING Henry Ritter, Nashville, Tenn, assignor to Avco Corporation, Nashville, Tenn, a corporation of Delaware Filed June 1, 1964, Ser. No. 371,686 8 Claims. (Cl. 109-84) This invention relates to lightweight armor plating, and more particularly to a collapsible honeycombed or corrugated armor plate construction in which the honeycomb or corrugated cells may be filled with sand or other granular material prior to use.
The prior art has provided many armor plating arrangements for preventing the passage of a projectile. These constructions range from sandbags, which have proved relatively efifective for limited applications, to sophisticated laminated constructions. By and large, the object of each of the constructions is to decrease the penetrative power of a projectile striking the armor plate by deflecting the course of the projectile. The major defect in sandbags is that even a small tear results in a loss of sand, while the major defect of the more elaborate schemes is excessive weight, primarily during transportation.
The primary object of this invention is to provide an armor plating construction having even greater effectiveness in preventing projectile penetration than the sandbag, and having the advantage over other arrangements of light weight and minimum volume when not in use or when being transported prior to use.
Another object of this invention is to provide armor plating comprised of a sandwich of sheet metal plates or reinforced plastic skins with a flexible honeycomb or corrugated core fillable with a granular material, such as sand.
Another object of this invention is to provide armor plating of a cellular construction in which the cells are filled with sand, the edge members of the sandwich construction being closable to retain the sand within the cells during use in an upright position.
Still another object of this invention is to provide armor plating consisting of two spaced sheet metal or reinforced plastic panels having a collapsible cellulor core, the cells of the core being fillable with projectile-resisting material.
For a better understanding and for further objects of this invention, reference should now be made to the following detailed specification in which:
FIGURE 1 is a plan view of the armor plating construction provided by this invention;
FIGURE 2 is a section taken through the line 22 of FIGURE 1;
FIGURE 3 is a section taken through the line 3-3 in FIGURE 1; and
FIGURE 4 is a perspective view showing the armor plating construction in a semi-collapsed position.
The collapsible armor plate of this invention comprises a rigid vertical rear panel 10, a vertical front panel 12, and vertical side panels 14 and 16 hinged together at the vertical edges by means of hinges 18, 20, 22, and 24. The top and bottom of the assembled vertical panels are closable by means of a top panel 26 having a vertical flange 26a and pivoted to the top horizontal edge of front panel 12 by means of a hinge 28, and a bottom panel 30 having a vertical flange 30a and pivoted to the bottom horizontal edge of front panel 12 by means of a hinge 32. When the top and bottom panels 26 and 30 are in the closed position; i.e., when the flanges 26a and 30a abut the rear wall 10, a rigid box-like structure is formed. However, when the top and bottom panels 26 and 30 are pivoted outwardly, as shown in FIGURE 4, the structure then becomes collapsible.
The inner side of the front panel 12 is lined with a self-sealing liner 34 comprised of any of the suitable wellknown rubber or plastic compounds used, for example, for lining fuel tanks of military aircraft. Flexible material 36, such as reinforced canvas or other fabric, to provide additional resistance to projectile travel, is secured by cementing, or by any other suitable means, at various vertical positions spaced along the rear panel 10 and at various intermediate vertical positions along the liner 34 of the front wall 12. The material 36 is thus corrugated, or formed into a cellular honeycomb or corrugated configuration, the cells of which are vertically oriented and fillable with sand 38 or other granular material.
For the purpose of mounting the armor plate on the apparatus to be protected; for example, on a tank, truck, or other military-type vehicle, or on a shelter, or to form a shelter, holes 40 are provided in each of the four corners of the rear plate 10 and in the corresponding locations of the flanges 26a and 30a when in the closed position.
For transporting the armor plate, the apparatus is emptied of sand by simply removing the bolts securing the bottom flange 30a to the rear panel ll), thereby permitting the opening of the bottom panel 3|) and draining the sand from the cells of the honeycombed or corrugated flexible material 36. To reduce the volume of the thenemptied armor plate, the upper panel 26 may be pivoted from its horizontal position to a vertical position, and the entire structure may be collapsed, the material 36 compressing into folds. In this condition, the armor plate has minimum Weight and minimum volume.
For actual use on a military vehicle, the armor plate may be installed while empty and then filled with sand or other granular material prior to actual need. In the event that a projectile pierces the front Wall 12, only the sand in a cell adjacent the rupture of the front wall is permitted to escape to the extent not otherwise prevented by the self-sealing action of the liner 34. This is highly advantgeous as compared with a sandbag which is generally rendered entirely ineffective once it has been ruptured and the sand is permitted to flow from it.
Thus, the armor plate of this invention has the advantages of a construction in which the granular material 38 is not removable, and yet retains most of the advantages of the ordinary sandbag which may be filled in the field prior to use.
Although the armor plate is shown as a complete assembly mountable on apparatus to be protected, it is within the purview of this invention that the structure illustrated may comprise a permanent part of the apparatus, e.g., the panel 10 may constitute the inner wall of a vehicle to which the remaining panels are hinged. Moreover, while canvas or fabric is illustrated as the material for forming the corrugation, many other materials are also available; for example, the material may be comprised of hinged sheet metal or it may be comprised of other bulletproof-type flexible materials which may be secured in a manner similar to canvas.
Many other modifications and adaptations will at once become apparent to persons skilled in the art, and it is intended therefore that this invention be limited only by the scope of the appended claims as interpreted in the light of the prior art.
What is claimed is:
1. A laminated armor plate comprising:
first, second, third, and fourth rectangular side panels hinged at adjacent parallel edges to form a collapsible rectangular box-like structure with two opposing open ends;

2. The invention as defined in claim 1 wherein one of said first, second, third, and fourth side panels is a front side panel, and wherein the interior of said front side panel is lined with a self-sealing liner.
3. The invention as defined in claim 2 wherein said open ends are closed by means of fifth and sixth rectangular panels hinged to opposite edges of said front panel.
The invention as'defined'in' claim S'Whereinsaid front panel is in a vertical plane, and wherein said fifth and sixth panels are top and bottom panels, respectively.
