Bulletproof Backpack
A bulletproof backpack includes a skin that forms a pocket, a pair of shoulder straps coupled to the skin, a water-resistant bulletproof-panel pocket located on an interior surface of the skin, the bulletproof-panel pocket being suitable for holding a bulletproof panel of sufficient size and in a position to protect a wearer of the backpack from a bullet, and a removable bulletproof panel within the pocket.
The present invention relates generally to backpacks, and more particularly relates to a backpack that is capable of stopping bullets.
BACKGROUND OF THE INVENTIONBackpacks are well-known to the general public and are most commonly used by students for carrying academic materials to, from, and during school. They are also used for a wide variety of other purposes, including transporting clothing and other personal effects during travel.
Most backpacks are made of a durable fabric outer material that forms a hollow pocket for holding items, such as books and other personal belongings. An opening for gaining access to the chamber is often sealed with a zipper mechanism.
In recent years there has been a series of tragic and well-publicized shootings that have taken place inside a number of learning institutions. Media coverage of these events has frequently shown students running away from school buildings in an attempt to avoid gunfire. Such coverage also tells unfortunate stories of students trapped inside buildings where they hid under desks, inside closets, behind doors, and in any other place they could find. Sadly, many of these innocent young students were hit by bullets and were seriously injured or died.
This is due, at least in part, to the fact that the students did not have bullet-stopping material available to them and positioned between them and the gunman.
In addition, there are many instances where children's lives are at risk in situations other than in schools. For instance, many people earn a living guarding children of wealthy parents or children that grow up in dangerous areas, such as countries at war.
One of the few items that most students have available to them at all times is their backpacks. U.S. Pat. No. 4,830,245 teaches a military backpack with a large rectangular frame. The entire frame is then wrapped with KEVLAR material. KEVLAR is the DuPont Company's registered trademark for a particularly light but very strong synthetic fiber that is particularly well suited bulletproof applications. Fibers of KEVALR consist of long molecular chains produced from poly-paraphenylene terephthalamide, which do not rust or corrode. There are many inter-chain bonds making the material extremely strong. KEVLAR derives a portion of its improved strength from inter-molecular hydrogen bonds formed between the carbonyl groups and protons on neighboring polymer chains and the partial pi stacking of the benzenoid aromatic stacking interactions between stacked strands. When KEVLAR is spun in the same way that a spider spins a web, the resulting fiber has tremendous strength.
The '245 backpack, however, is disadvantageous in that the frame is large and heavy, is one solid piece that can not easily be stored, and is very expensive due to the fact that the entire frame is wrapped in KEVLAR material. In addition, KEVLAR becomes significantly less effective once it is exposed to water. Also, the bullet resistant properties of KEVLAR also diminish upon exposure to ultraviolet light, including sunlight. Therefore, once the '245 backpack is subjected to rain or sunlight, its effectiveness at stopping bullets is in compromised.
Therefore a need exists to overcome the problems with the prior art as discussed above.
SUMMARY OF THE INVENTIONBriefly, in accordance with the present invention, disclosed is an apparatus for mitigating the consequences of school violence by providing students with a simple device for protection against ballistic and other impacts. Embodiments of the present invention improve upon the prior art by providing a backpack which allows for better functionality with regards to intended use by students or other users.
The present invention provides a backpack with at least one protective plate contained within the interior of the backpack. In one embodiment, the protective plate is made of a bullet-stopping material, such as KEVLAR. Because the panel is housed on an interior of the backpack, the KEVLAR plate is thereby itself protected against moisture and exposure to direct sunlight. The backpack, in one embodiment, is generally rounded in shape, with a flat bottom, back, and front. The sides of the backpack need not be rigid and may be constructed of known durable but non-rigid fibers such as nylon or other blends, similar to known student backpacks. Two adjustable carrying straps are attached to the back exterior of the backpack in order allow easy transporting over the carrier's shoulders, especially when the backpack is used for carrying a heavy load; as such, the straps may contain extra padding. However, the backpack need not be in any one particular configurations so long as it is configured to be carried over the user's two shoulders and can accommodate the dimensions and weight of at least one KEVLAR plate.
In one embodiment, the interior of the back panel of the backpack provides a pouch or otherwise separate envelope-like holder to keep the Kevlar plate separate from the remainder of the interior.
The panel itself may either be a single panel, or a combination of two or more panels removably connected to each other by a strap mechanism that allows for one of the panels to be removed from the backpack, moved over the carrier's head, and placed against the carrier's chest. In this dual-panel embodiment, it may be necessary to secure the rear panel to the interior of the backpack; in a single-panel embodiment, this securing may be preferred, but is not necessary.
In accordance with a particular embodiment, the present invention includes an outer skin forming a pocket and a bulletproof panel coupled to an interior of the pocket.
In accordance with another feature, the bulletproof panel is removable.
In accordance with a further feature of the present invention, an inner pocket is located within the interior of the pocket and adapted to at least partially contain the bulletproof panel.
In accordance with a further feature of the present invention, the inner pocket is water-resistant.
In accordance with another feature, a second bulletproof panel is coupled to an exterior of the backpack.
In accordance with yet another feature, at least one strap couples the second bulletproof panel to the exterior of the skin and at least one strap is adapted to secure the second panel on a first side of a user and the pocket on a second side of the user.
With objects of the invention in view, there is also provided a skin forming a pocket, a pair of shoulder straps coupled to the skin, a water-resistant bulletproof-panel pocket located on an interior surface of the skin, the bulletproof-panel pocket adapted for holding a bulletproof panel of sufficient size and in a position to protect a wearer of the backpack from a bullet.
The accompanying figures where lice reference numerals refer to identical or functionally similar elements throughout the separate views and which, together with the detailed description below, are incorporated in and form part of the specification, serve to further illustrate various embodiments and to explain various principles and advantages all in accordance with the present invention.
While the specification concludes with claims defining the features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the drawing figures, in which like reference numerals are carried forward. It is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure. Further, the terms and phrases used herein are not intended to be limiting; but rather, to provide an understandable description of the invention.
The present invention, according to an embodiment, overcomes problems with the prior art by providing a backpack with bullet impeding or stopping ability. The inventive backpack, when placed between a person and a gunman, will protect a covered portion of the person by preventing a bullet from making unimpeded contact with the person's body.
Described now are exemplary embodiments of the present invention. With reference to the drawings,
Furthermore,
The back surface 204 of the backpack 100 is a substantially flat surface that rests comfortably against the carrier's back. The interior panel 202, in one embodiment rests against the interior side of the back surface 204. In another embodiment, the panel 202 rests against the exterior side of the back surface 204.
Straps 102 allow for easy carrying and distribution of weight. The straps 102 ideally include padding along their lengths so as to reduce the stress from the weight of carrying the backpack, but this padding is not required of the invention.
The pocket 304 has a securing mechanism 306, which, in this embodiment, is a zipper. However, the securing mechanism 306 is not limited to a zipper, but can also include snaps, buttons, hooks, or any other fastener. Because KEVLAR is known to lose its bullet-stopping ability once it is exposed to moisture, in one embodiment, the pocket 304 is waterproof or water-resistant and the securing mechanism 306 is a waterproof-type sealer.
Therefore, the embodiment of the invention, as shown in
