Description

ARMORED CAB FOR VEHICLES
BACKGROUND OF THE INVENTION
1. Related Applications
[0001] This application claims the benefit of U.S. Provisional Patent Application Serial No. 61/003,365, filed November 16, 2007, and entitled Armored Cab for Vehicles.
2. Field of the Invention
[0002] Various types of vehicles, such as joint light tactical vehicles (JLTV), tactical vehicles, or tactical trucks, and similar vehicles used in a battlefield, or other armed conflict situations, may sustain land mine strikes, or attacks from improvised explosive devices (IED), such as roadside bombs. It would be desirable for these vehicles to be able to withstand the forces of the foregoing types of attacks and explosions to enhance the survivability of the occupants of such vehicles. By armoring the cab, or passenger cabin, of a vehicle, the survivability of the occupants of the vehicle may be enhanced.
3. Description of the Related Art
[0003] It is often desirable to transport soldiers, non-military personnel, and equipment across hostile territory via motorized land vehicles such as tactical vehicles, tactical trucks, and similar vehicles. During transport, however, people occupying the cab of the vehicle are susceptible to injury from IEDs, land mines, and other bombs and explosives. To reduce injury from these encounters armor plating has been added to the cabs of such vehicles.
[0004] Without wishing to be bound by the theory, typically prior vehicle cabs were armored by increasing blast resistance through increased material strength and thickness, as well as increasing blast deflection through the use of angular and "V" shaped structures. Accordingly, the armoring of the foregoing vehicles has been achieved by using thick flat panels, or flat surfaces, of armor plate material for, or upon, the walls of the cabin, or passenger cabin.
SUMMARY OF THE INVENTION
[0005] In accordance with one embodiment of the present invention, an armored cab is provided. The cab preferably includes 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.
[0006] In accordance with another embodiment of the present invention, the bottom wall of the cab further includes at least one convex surface having a convex shape. In a preferable embodiment, the concave surface and the convex surface are disposed in a direction substantially parallel with a longitudinal axis of the armored cab.
[0007] In accordance with another embodiment of the present invention, an armored cab is provided. The cab preferably includes 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 a first and second concave surface, which face downwardly and away from the armored cab, and are disposed in a direction substantially parallel with the longitudinal axis of the armored cab. The first concave surface is disposed in alignment with a forward, or front, portion of a floor of the cab, and the second concave surface is disposed in alignment with a rearward, or rear portion of the floor of the cab. Preferably, the first and second concave surfaces are integral with the bottom wall, and centrally disposed between the at least two side walls. Continuing with the embodiment, the bottom wall further includes a first and second convex surface disposed in the direction substantially parallel with the longitudinal axis of the armored cab. The first convex surface extends along a first lower-most portion of the bottom wall, and the second convex surface extends along a second lower-most portion of the bottom wall. 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.
[0008] For the purpose of this disclosure, geometric terms such as "circle", "sphere", "oval," and the like are used as references and for clarity of understanding, as would be understood by one of ordinary skill in the art. Accordingly, these terms should not be limited to strict Euclidean standards.

DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS
[00017] With reference to FIGS. 1-4, a portion of a cab, or armored cab, 70 for use with a vehicle, such as a JLTV, tactical vehicle, truck (not completely shown), combat vehicle, cargo truck, or troop transport vehicle is shown. The cab, or armored cab, 70 generally includes: at least one upper wall, or upper wall surface, 72; preferably at least two side walls, or side wall surfaces, 73; at least one front wall, or front wall surfaces, 74; at least one back wall, or back wall surfaces, 75; and at least one floor, or bottom wall, or bottom wall surface, 76. The upper wall 72 may be provided with an opening 77 for a gun turret (not shown). At least one, and preferably two, doors 78 (shown in FIG. 4) may be provided in openings 78' in the side walls 73. The front wall surfaces 74 may be provided with at least one, and preferably two, windows 80. Preferably, the windows 80 are made from any suitable bulletproof material which is transparent and affords the desired visibility for the occupants (not shown) of the armored cab 70, while at the same time affording protection against the explosive forces previously described.
[00018] Still with reference to FIGS. 1-4, the armored cab 70 is manufactured from materials having the requisite strength characteristics to withstand the explosive forces previously described. At least some, and preferably all, of the walls 72, 73, 74, 75, and 76 of armored cab 70, and doors 78 are made from an armor plate material, which is known as high hard steel, or armor steel, or other similar material having the requisite strength characteristics to withstand the forces encountered in a battlefield, or other type of conflict situation. Alternatively, the armor plate material may be affixed to, or riveted (using rivets 79) to, at least some, and preferably all, of the walls 72, 73, 74, 75, and 76 of armored cab 70, and doors 78. Preferably, to provide protection to the occupants of armored cab 70 against IEDs, land mine strikes, and similar explosions from beneath armored cab 70, or bottom wall surface 76 of armored cab 70 may include at least one concave surface 90.
[00019] Preferably, the at least one concave surface 90 is of a smooth concave shape, and thus forms an inwardly hollow rounded arch. In an embodiment, the concave surface 90 includes at least one concave wall surface 91, and is generally disposed, along a length of the cab 70, in a direction substantially parallel with the longitudinal axis 92 of cab 70. Alternatively, as shown in FIG. 3, the concave surface 90 includes a forward concave wall surface 91', and a reward concave wall surface 91. Preferably, the concave surface 90 extends substantially the entire length of the cab 70. Preferably the forward concave wall surface 91 ', and the reward concave wall surface 91 extend, or face, downwardly toward the ground, or roadway (not shown), and away from the cab 70. The at least one concave surface 90, the forward concave wall surface 91 ', and the reward concave wall surface 91, may take any arched concave shape, including spherical, oval, egg, conical, cylindrical, and the like shapes. Accordingly, the at least one concave surface 90, the forward concave wall surface 91', and the reward concave wall surface 91, may have a curvature equal to the curvature of the surface of a sphere having one particular radius. Alternatively, the surface of at least one concave surface 90, the forward concave wall surface 91', and the reward concave wall surface 91, may have a curvature equal to the curvature of the surface of a oval having two different radii. [00020] The at least one concave surface 90 is preferably disposed substantially parallel to the longitudinal axis 92 of cab 70, and disposed substantially intermediate the side walls 73 of cab 70. In an embodiment, the at least one concave surface 90 is disposed centrally between the side walls 73, and substantially parallel to the longitudinal axis 92 of the cab 70. The at least one concave surface 90 may be disposed beneath a portion of the floor 100 of the cab 70. Alternatively, as shown in FIG. 3, a first concave wall surface 91 ', is disposed beneath a forward, or front portion of the floor 100 of the cab 70, and a second concave wall surface 91, is disposed beneath a rearward, or rear, portion of the floor 100 of the cab 70. The first concave wall surface 91' and the second concave wall surface 91 are preferably disposed substantially parallel with respect to each other, substantially parallel to the longitudinal axis 92 of cab 70, and substantially intermediate the side walls 73 of cab 70. In an embodiment, the at least one concave surface 90 forms the transmission tunnel of a vehicle such as a JLTV, and the like tactical vehicles.
[00021] In the event of a mine blast or explosion of an IED beneath cab 70, the concave surface 90 contains and manages, or mitigates, the blast effects from the explosion. The concave surface 90 affords cab 70, and in particular the bottom wall surface 76, with increased structural strength which reduces dynamic and permanent deformation of the bottom wall surface 76 of the cab 70. Blast resistance is further enhanced from the strength of the armor plate material utilized for concave surface 90. If desired, the at least one concave surface 90, and/or concave wall surface 91 may be provided with locally applied stiffening ribs (not shown). Blast resistance may be further improved with generally known and specialized welding, as well as joint re-enforcement techniques.
[00022] With reference to FIGS. 1-4, armored cab 70 may include flat panels, 105 which are angularly disposed with respect to each other which also form a portion of the bottom wall surfaces 76 of cab 70. These panels assist to deflect the previously described explosive blasts.
[00023] Turning now to FIGS. 5 and 6, another embodiment of a portion of an armored cab 70' is illustrated. In this embodiment, armored cab 70' not only includes at least one concave surface 90, as previously described, but also includes at least one convex surface 110. The at least one convex surface 110 preferably forms a portion of the bottom wall surface 76. The at least one convex surface 110 may take any arched convex shape, including spherical, oval, egg, conical, cylindrical, elliptical, and the like shapes. Accordingly, the surface of the at least one convex surface 110 and the at least one convex wall surface 111 may have a curvature equal to the curvature of the surface of a sphere having one particular radius. Alternatively, the surface of the at least one convex surface 110 and the at least one convex wall surface 1 11 may have a curvature equal to the curvature of the surface of a oval having two different radii. In an embodiment, the convex surface 110 and the at least one convex wall surface 111 have a smooth shape. In an embodiment, the at least one convex surface 1 10 includes at least one convex wall surface 11 1, which extends, along a length of the cab 70, in a direction substantially parallel to the longitudinal axis 92 of cab 70', along the lower-most portion of bottom wall surfaces 76. The convex wall surface 111 may face toward the cab 70'.
[00024] In a preferred embodiment, there are two convex wall surfaces 111, each extending substantially parallel to the longitudinal axis 92 of cab 70', along the lower-most portion of bottom wall surfaces 76. Preferably, each of the convex wall surfaces 111 extend substantially the entire length of the cab 70'. Each of the two convex wall surfaces 11 1 are preferably tangent with its respective flat panel 105, which is tangent with its respective side wall 73. In this embodiment, the first convex wall surface 1 11 is disposed beneath and exterior to the at least one concave surface 90 on a first side of the at least one concave surface 90, and the second convex wall surface 111 is disposed beneath and exterior to the at least one concave surface 90 on a second side of the concave surface 90. Preferably, the first and second sides of the at least one concave surface 90 oppose one another. In this manner, the at least one concave surface 90 is disposed between the first and second convex wall surfaces 1 1 1. These convex surfaces 110, or convex wall surfaces 111, provide blast resistance against explosive forces resulting from mine blasts and IED explosions. The structural strength from the convex surfaces 110, or convex wall surfaces 11 1, help reduce dynamic and permanent deformation of the bottom wall surfaces 76 of cab 70 upon encountering explosive forces. The convex surfaces 110, or convex wall surfaces 1 1 1, may be provided, if desired, with locally applied stiffening ribs (not shown). Blast resistance may be further improved with generally known and specialized welding, as well as joint re- enforcement techniques.
[00025] Specific embodiments of the present invention have been described and illustrated. It will be understood to those skilled in the art that changes and modifications may be made without departing from the spirit and scope of the inventions to be defined by the appended claims.
