BACKGROUND OF INVENTION —FIELD OF INVENTION
This invention protects the exterior of a vehicle from projectiles and is affixed by electromagnets.
BACKGROUND OF INVENTION—PRIOR ART
The retrofitting of vehicles with armor to protect the exterior of the vehicle or passengers has been described in the prior art. U.S. Pat. No. 1,913,554 to Luker (1933) is one such example, in which armor plating is affixed to the front of a vehicle. U.S. Pat. No. 2,363,573 to Costa (1944) discloses an armored shell, albeit to install the armored shell entails that all parts not essential to the operation of the vehicle need to be removed. U.S. Pat. No. 4,352,316 to Medlin (1982) discloses a lightweight armored vehicle and method of making same using woven polyester glass protective sheets. In Medlin (1982), the interior furnishings must be stripped, doors, and windows rebuilt in order to mount a bullet-proof, transparent window. U.S. Pat. No. 6,327,954 to Medlin (2001) discloses prefabricated, lightweight composite armor that protects the interior cab of a vehicle, but not the rest of the vehicle, e.g. hood, side panels, and trunk. U.S. Pat. No. 5,370,035 to Madden, Jr. (1994) discloses a bullet-proof apparatus for the back side of a front seat. Another bullet-proof assembly, this time for the interior side of a door panel, is disclosed by U.S. Pat. No. 6,027,158 to Yang (2000). Another example of retrofitting of the interior with armor is U.S. Pat. No. 6,041,689 to Lair et al (2000).
U.S. Pat. No. 3,855,898 to McDonald (1974) discloses a transparent, bullet-proof plastic panel fastened by metal clips or fabric straps to the windshield and windows. McDonald (1974) also discusses a protective panel that can be attached to the inside of a side door or other parts of the vehicle.
In the prior art, examples of removable armor include U.S. Pat. No. 5,811,719 to Madden, Jr. (1998). Madden, Jr. (1998) discloses a flexible, bullet-proof curtain that secures to the interior side of a door. U.S. Pat. No. 5,531,500 to Podvin (1996) discloses a bullet-proof panel affixed to the exterior surface of a door, in which the shape conforms to the contour of the sheet metal. To fasten a protective layer to the vehicle, magnets have been employed in several instances in the prior art. For example, U.S. Pat. No. 3,147,176 to Haslam (1964) is a magnetic protector strip for a car door. U.S. Pat. No. 4,810,015 to McNeil (1989) and U.S. Pat. No. 5,312,145 to McNeil (1994) disclose a motor vehicle body protection apparatus which covers part of the exterior of door, and is affixed by magnets. However, McNeil's disclosure is only meant to cover a strip of the door, enough to protect the door from another vehicle's door, as commonly encountered in the context of a parking lot. U.S. Pat. No. 6,161,462 to Michaelson (2000) discloses a bullet-proof blanket, affixed by magnets, for use with law enforcement vehicles such as police vehicles. Conceived to be first installed when the officer happens upon a shootout, Michaelson's (2000) disclosure is therefore intended for stationary use only, that is, for the duration of the shootout.
U.S. Pat. No. 6,481,782 B2 to Bond (2002) discloses a small, light-weight, bullet-proof shield affixed on the side of a vehicle door, including a magnetic backing covered by a bullet-proof mesh material. U.S. Pat. No. 4,953,442 to Bartuski (1990) discloses a magnetized ferrous ceramic material encapsulated in a fiberglass layer.
A great deal of income is spent on the purchase of vehicles. While many of the vehicles produced have the capability to be used off-road, most are only used in an urban context. Excessive body damage such as scratches or dents from off-road use entail high repair costs. Not only are the repair costs expensive but the re-sale value of the vehicle decreases. The present invention, therefore, is primarily intended to protect the side panels of a vehicle when used both on-road or off-road. By use of a lightweight yet bullet-proof strength, protective polymeric material, potential damage to the exterior of a vehicle by sunlight, branches, projected rocks or other obstacles may be reduced.
With minor modifications, the present invention may be used in civilian, police, or military use. In police or military use, the cost of the protective cover is intended to be well below the cost entailed in the process of retrofitting armor to a vehicle. According to the shape of the vehicle, the electromagnetic protective cover may be tailored for an exact fit. Or, the protective cover may also be tailored to fit over a frame (e.g. a soft top) to cover passengers sitting in the back of a truck, or completely cover a vehicle such as a sport utility vehicle. The present invention, moreover, may be removed after the life span of a vehicle has expired and affixed to another vehicle.
A main novelty of the device is the use of electromagnetism. Electromagnetism ensures a close fit of the protective cover to the exterior of a vehicle. As long as current runs to the electromagnets, they are strongly affixed to the exterior of the vehicle.
BACKGROUND OF INVENTION—OBJECTS AND ADVANTAGES
A main object of the protective cover is to decrease or eliminate vehicular body damage as a consequence of regular on-road or off-road use regardless of road conditions and weather.
It is an object to tightly affix the protective cover to the body of the vehicle by way of electromagnetism. By sending current through insulated wire, which is wound around temporary magnets, a magnetic field is created around each soft iron bar.
It is an object to use the protective cover in either civilian, police, or military applications with modification according to the purpose. In the case of passengers occupying the back of the military truck, the protective cover may be expanded to fit over a roll-cage.
Another object is that the protective cover can be folded when not in use, placed in a suitcase, and stored in the trunk. Prior to off-road use, the protective cover can be quickly placed over the body of the vehicle.
It is an object that the external layer is made of a protective, water-proof material such as polypropylene in order to protect the electromagnets and insulated wires. After off-road use, the protective cover may be cleaned with water.
Another object is that an inner layer of the protective cover includes a bullet-proof material.
In order to deter theft when current does not flow to the temporary magnets, an object is to include a main strap and main strap lock. As deemed necessary, more straps and locks may be added to the design.
To ensure quick entry and exit from the vehicle, even when the protective cover is in place, an object is to include quick releasing latches located at the top of the doors. Once the latches are closed, a covering made of Velcro.RTM is pulled over the perforation and latches. The latches can be locked.
Another object is that a rounded pad, potentially made of rubber or plastic, protects the corners of the vehicle from contact with obstacles. Attached to the bottom of the rounded pad, an upper frame houses the insulated wire between a panel to an adjacent panel.
Another object is that an electrical plug on a panel and socket on an adjacent panel are located at the ends of the upper frame. When the plug and socket are connected, electrical current flows to each electromagnet.
A final object is to include permanent magnets to hold the protective cover in place during mounting or when current does not flow to the electromagnets.
SUMMARY
Affixed by electromagnets to the body of a vehicle, the cover affords bullet-proof protection to the vehicle during on-road and off-road use.
