Armored cab for vehicles

Abstract

An armored cab having at least an upper wall, two side walls, a front wall, a back wall, and a bottom wall. The armored cab and its respective walls include a longitudinal axis extending from the back wall to the front wall. The bottom wall includes at least one concave surface. The at least one concave surface faces downwardly and away from the armored cab, and is disposed in a direction substantially parallel with the longitudinal axis of the armored cab.

I claim:

         2 . The armored cab of  claim 1 , wherein the at least one upper wall, the at least two side walls, the at least one front wall, the at least one back wall, and the at least one bottom wall are formed from an armor plate material selected from the group consisting of high hard steel, armor steel, and the like. 
     
     
         3 . The armored cab of  claim 1 , wherein the at least one upper wall includes an opening for a gun turret. 
     
     
         4 . The armored cab of  claim 1 , wherein the at least one front wall surface further includes at least one window. 
     
     
         5 . The armored cab of  claim 4 , wherein the at least one window is bullet proof and transparent. 
     
     
         6 . The armored cab of  claim 1 , wherein the at least one concave surface is integral with the at least one bottom wall. 
     
     
         7 . The armored cab of  claim 1 , wherein the at least one concave surface includes at least one concave wall disposed in alignment with a forward portion of a floor of the cab. 
     
     
         8 . The armored cab of  claim 1 , wherein the at least one concave surface includes at least one concave wall disposed in alignment with a rearward portion of a floor of the cab. 
     
     
         9 . The armored cab of  claim 1 , wherein the at least one concave surface includes a first concave wall disposed in alignment with a forward portion of a floor of the cab and a second concave wall disposed in alignment with a rearward portion of the floor of the cab. 
     
     
         10 . The armored cab of  claim 1 , wherein the concave surface further includes stiffening ribs. 
     
     
         11 . The armored cab of  claim 1 , wherein the at least one bottom wall includes at least one convex surface. 
     
     
         12 . The armored cab of  claim 11 , wherein the at least one convex surface is integral with a lowest portion of the at least one bottom wall. 
     
     
         13 . The armored cab of  claim 11 , wherein the at least one convex surface is disposed in the direction substantially parallel with the longitudinal axis of the armored cab. 
     
     
         14 . The armored cab of  claim 11 , wherein a first convex surface and a second convex surface are disposed in the direction substantially parallel with the longitudinal axis of the armored cab, and the first convex surface and the second convex surface extend along a first lower-most portion and a second lower-most portion of the bottom wall. 
     
     
         15 . The armored cab of  claim 14 , wherein the first convex surface and the second convex surface are integral with the first and second lower-most portions of the bottom wall. 
     
     
         16 . The armored cab of  claim 15 , wherein the first and second concave wall surfaces are disposed between the first and second convex surfaces. 
     
     
         17 . The armored cab of  claim 11 , wherein the at least one convex surface includes at least one convex shaped wall. 
     
     
         18 . The armored cab of  claim 11 , wherein the at least one convex surface further includes stiffening ribs. 
     
     
         19 . An armored cab comprising:
 at least one upper wall, at least two side walls, at least one front wall, at least one back wall, and at least one bottom wall including a longitudinal axis extending from the at least one back wall to the at least one front wall;   the at least one bottom wall including:
 a first concave surface facing downwardly and away from the armored cab, and disposed in a direction substantially parallel with the longitudinal axis of the armored cab, and the first concave surface disposed in alignment with a forward portion of a floor of the cab; 
 a second concave surface facing downwardly and away from the armored cab, and disposed in a direction substantially parallel with the longitudinal axis of the armored cab, and the second concave surface disposed in alignment with a rearward portion of the floor of the cab, wherein the first and second concave surfaces are centrally disposed between the at least two side walls, and the first and second concave surfaces are integral with the bottom wall; 
 a first convex surface disposed in the direction substantially parallel with the longitudinal axis of the armored cab, and the first convex surface extending along a first lower-most portion of the bottom wall; and 
 a second convex surface disposed in the direction substantially parallel with the longitudinal axis of the armored cab, and the second convex surface extending along a second lower-most portion of the bottom wall, wherein the first convex surface and the second convex surface are integral with the first and second lower-most portions of the bottom wall, and the first and second concave wall surfaces are disposed between the first and second convex surfaces.
