Referring now specifically to the drawings, FIGS. 1-3 illustrate an exemplary embodiment of a tactical self-propelled motor vehicle “V” incorporating a vehicle-mounted personnel access platform assembly with ballistic protection. The platform assembly is indicated generally at reference numeral 10. The ballistic protection may comprise, for example, a hard or soft armor ballistic wall 12. In addition to the assembly 10, the tactical vehicle “V” may comprise wheels 14 and a vehicle body 15 including side doors and windows, and other generally conventional parts and assemblies (not shown) including, for example, a heavy duty chassis, suspension, engine, clutch, gears, differential, drive shaft, driveline, drive train, transmission, and axles.
In the exemplary embodiment shown, the tactical vehicle “V” further comprises an elevated personnel deck 16 (or ramp) carried by a vehicle-mount frame assembly 18, and defining a substantially flat and continuous deck surface for supporting personnel. The elevated deck 16 extends from the front to the rear of the vehicle “V”, and may comprise safety rails 19 and one or more adjustable or pivoted deck sections. For example, the front ramp may be designed to pivot and elevate via one or more hydraulic actuators (not shown). One example of an adjustable front end ramp system applicable for use in the present vehicle is described in Applicant's prior issued patent, U.S. Pat. No. 6,832,667. The complete disclosure of this prior patent is incorporated herein by reference.
Referring to FIGS. 3-8, the present platform assembly 10 comprises a selected arrangement of elevated horizontal access platforms 21, 22. Each access platform 21, 22 may include a generally rectangular foot tread having opposing longitudinal front and back ends, and opposing side ends. The access platforms 21, 22 are carried by respective pairs of vertical mounting braces 24, 25, 26, and 27 attached at one side of the vehicle “V”; each mounting brace 24-27 comprising a generally C-shaped elongated support 30 (or “stringer”). In one embodiment, the top end of each support 30 is bolted to a horizontal I-beam 31 (FIG. 3) fixed to the roof of the vehicle “V” adjacent the personnel deck 16, while the bottom end is bolted to the vehicle chassis. Each mounting brace 24-27 defines a series of vertically-spaced holes 32, and a bracket assembly comprising cooperating horizontal and angled support brackets 34 and 35. The horizontal and angled brackets 34, 35 attach directly to the vertical support 30 using, for example, removable bolts or pins (not shown) passed through the brackets 34, 35 and into, or through, selected mounting holes 32. The angled bracket 35 extends from a distal end of the horizontal bracket 34 to the vertical support 30. Once located on the vertical support 30, a second identical bracket assembly may be attached at an identical elevation to a second mounting brace 24-27 secured to the vehicle “V”. One or more platforms 21, 22 extend between the spaced mounting braces 24-27, and are vertically supported (at least in part) by the bracket assemblies. The load capacity at any point along a platform 21, 22 may be in the range of 250-1000 pounds. The elevations of the platforms 21, 22 may be readily modified in the field by adjusting the location of each horizontal bracket 34 along respective lengths of the vertical supports 30. The platforms 21, 22 may rest freely on the horizontal brackets 34, or may be more securely attached using appropriate hardware, ties, straps, welding, or other means.
As best shown in FIGS. 3 and 8, the ballistic wall 12 may be located adjacent an area of the platforms 21, 22, and spaced-apart from the body 15 of the tactical vehicle “V” to form a protected personnel access (or staging) location. In the present embodiment, the ballistic wall 12 is carried by a pair of vertical wall standards 41, 42 attached to opposite ends of a single platform 21 using, for example, mounting plates and angled brackets 43A and 43B (See FIG. 8). Each standard 41, 42 may comprise a substantially vertical lower section 44, an outwardly angled upper section 45, and a perforated reinforcing web 46. The upper section 45 is formed at an angle (“α”) of approximately 30 degrees, and comprises a wall-hanging end edge 48 designed to engage a generally horizontal reinforcing bar 49 affixed to a personnel-side surface of the ballistic wall 12. The reinforcing bar 49 is located proximate a top of the wall 12, and may extend substantially from one end of the wall to the other. By this exemplary construction, the ballistic wall 12 hangs vertically from the cooperating wall standards 41, 42, and is substantially spaced from the access platform 21 to form a sizeable zone of safety sufficient to accommodate one or more individuals, gear, and equipment. As best shown in FIGS. 3, 7, and 8, the unobstructed space between a bottom end of the ballistic wall 12 and a front edge of the access platform 21 defines a deployment passageway 50 for conveniently transferring personnel, gear and equipment to and from the elevated platforms 21, 22. Additionally, the ballistic wall 12 may be freely pivotable at the reinforcing bar 49, and readily lifted and removed from the wall standards 41, 42 to facilitate more rapid deployment. Alternatively, the ballistic wall 12 may be more securely mounted using brackets, braces, and other hardware.
The ballistic wall 12 may be constructed of any suitable hard and/or soft armor material including, for example, ceramics, Kevlar®, Twaron®, aramid fibers, HDPE, or other high performance fiber having a tensile strength greater than 7 grams/denier. The platform assembly 10 can be removed and/or installed on either side or end of the tactical vehicle “V”. In various exemplary implementations, the platform assembly 10 may provide a protected staging location for military personnel at heights of 6-12 feet, and is applicable in law enforcement for police access to bus and perimeter security.
Exemplary embodiments of the present invention are described above. No element, act, or instruction used in this description should be construed as important, necessary, critical, or essential to the invention unless explicitly described as such. Although only a view of the exemplary embodiments have been described in detail herein, those skilled in the art will readily appreciate that many modifications are possible in these exemplary embodiments without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention as defined in the appended claims.
In the claims, any means-plus-function clauses are intended to cover the structures described herein as performing the recited function and not only structural equivalents, but also equivalent structures. Thus, although a nail and a screw may not be structural equivalents in that a nail employs a cylindrical surface to secure wooden parts together, whereas a screw employs a helical surface, in the environment of fastening wooden parts, a nail and a screw may be equivalent structures. Unless the exact language “means for” (performing a particular function or step) is recited in the claims, a construction under §112, 6th paragraph is not intended. Additionally, it is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.
