STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
Not applicable.
BACKGROUND OF THE INVENTION
Field of Invention
There are many millions of police officers in the United States and worldwide. These officers frequently encounter dangers that entail ballistic attacks. So that officers are protected in these situations, standard bullet-resistant vests (e.g., Kevlar® vests) are made available to every police officer.
Although readily available, police officers do not always wear ballistic-resistant vests in dangerous situations. One reason that the vests are not worn is that the standard ballistic-resistant vest can trap heat, which frequently results in life-threatening heat buildup within the vest. Life-threatening overheating due to heat-buildup by a ballistic-resistant vest is so frequent that an estimated one-half of the nearly one-million police officers in the United States do not wear their vests out of overheating fears. Even when the heat trapped by the vest is not life-threatening, it is uncomfortable for the wearer. Forgoing a vest to avoid overheating and discomfort is so common that police officers with no vest colloquially jest, “I'd rather die comfortably [from a ballistic attack than wear a vest and die from overheating].”
In view of the foregoing, a need exists for ventilation systems for ballistic resistant vest and related methods of creating a cooling barrier between a body and a ballistic vest. Some have attempted to meet this need with an undergarment or shirt that has sewn-in foam spacers which create ventilation spaces between the vest and wearer's torso. See, e.g., U.S. Pat. No. 8,756,718 (issued Jun. 24, 2014) and U.S. Pat. No. 4,451,934 (issued Jun. 5, 1984). However, sewn-in foam spacers are readily compressible and subject to failure so that heat venting spaces between the vest and wearer are often non-existent or kinked. Also, the foam can act as heat-trapping insulation that exacerbates the overheating problem. Furthermore, sewn in spacers have a tendency to bunch together and can, as a result, lead to discomfort or encumber the wearer's movement. Finally, foam spacers cannot contribute to the efficacy of a vest's ballistic-resistance. Thus, a need still exists for a ventilation system for a ballistic-resistant vest and related methods of creating a cooling barrier between a body and a ballistic-resistant vest.
SUMMARY OF THE INVENTION
Based on the foregoing, it is an object of this disclosure to describe ventilation systems for a ballistic resistant vest and related methods of creating a cooling barrier between a wearer's body and a ballistic-resistant vest. It is a further objective to describe vest cooling systems and related methods that do not readily fail or cause discomfort to a user. Finally, it is a primary objective of this disclosure to allow police officers to wear ballistic resistant vests without the fear of life-threatening or uncomfortable overheating.
In a preferred embodiment, the ventilation system may be defined by at least one panel of a flexible and semi-rigid plastic comprised of vented grooves. In one embodiment, the panel is roughly the size and shape of a panel of Kevlar® commonly used in under-uniform bullet-resistant vests. In one embodiment, the grooves of the panels features holes to permit the transmission of sweat therethrough. In one mode of use, the vented panels may be placed between the vest and undershirt of a wearer so that the grooves create a slight, but highly effective, separation of the vest and body. Suitably, the tension of the vest against the body is sufficient to hold the panel in place between the body and the vest. In a preferred embodiment, the separation of the vest from the wearer's body is approximately one-half inch. In one embodiment, the separation of the vest and wearer keeps the user dry and cool by allowing constant airflow. In another mode of use, the vented panel may be wiped-down with a cleaning device (e.g., a cloth) after use.
Other objectives and desires may become apparent to one of skill in the art after reading the below disclosure and viewing the associated figures. Also, these and other embodiments will become apparent from the drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
In general, disclosed are ventilation systems for a ballistic resistant vest and related methods of creating a cooling barrier between a wearer's body and a ballistic resistant vest. In a preferred embodiment, the ventilation system may be defined by a panel that features vented grooves. In a preferred mode of use, the panel is preferably positioned between a vest and the torso of a wearer of the vest whereby a space is created therebetween the vest and wearer. When the space is created, air may freely flow through the space to cool the wearer. Suitably, the tension of the vest against the body is sufficient to hold the panel in place between the body and the vest. The more specific details of the disclosed system are described in connection with the figures.
FIG. 1 is a perspective view of a ballistic resistant vest 2000. Generally, the vest 2000 features a front 2100, back 2200, arm holes 2300, and a neck hole 2400. As shown, the vest 2000 is preferably constructed in any manner or by any style known to those of skill in the art. Suitably, the vest 2000 may be worn over the torso (not shown) of a wearer in the manner known to those of skill in the art. As shown in broken lines, a panel 1000 may be preferably disposed behind the front 2100 of the vest 2000, between the vest 2000 and a wearer (not shown) when worn. Suitably, the tension of the vest 2000 against the body is sufficient to hold the panel 1000 in place between the wearer's body (not shown) and the vest 2000.
FIG. 2 is a perspective view of the ballistic resistant vest 2000 with the front 2100 partially upturned to expose the vented panel 1000. The figure is an environmental view that shows (a) the positioning of the panel 1000 when worn and (b) the features of the panel 1000. As shown, the panel 1000 may suitably be positioned between the front 2100 of the vest 2000 and a wearer (not shown). Still referring to FIG. 2, the panel 1000 is defined by an array of “valleys” 1100 and “peaks” 1200 with sidewalls 1300. In the figures, the valleys 1100 are positioned toward the wearer (not shown) while the peaks 1200 are positioned toward the vest 2000. When in use, the valleys 1100 abut the wearer (not shown) while the peaks 1200 abut the inside of the vest 2000 so that the sidewalls 1300 create a plurality of vent spaces between (a) the vest 2000 and panel 1000 and (b) the wearer (not shown) and panel 1000. In the depicted embodiment, the valleys 1100 features holes 1110 for allowing perspiration to pass therethrough when the same are abutted to a wearer's body (not shown).
FIG. 3 is a perspective view of a vented panel 1000 shown in FIG. 2. FIG. 4 is a front view of the vented panel 1000 of FIG. 3. FIG. 5 is top view of the vented panel 1000 of FIGS. 3 and 4. FIG. 6 is a right-side view of the vented panel 1000 of FIGS. 3 through 5. Referring first to FIGS. 3 and 4, the panel 1000 is a hexagon sheet that is roughly the dimensions of a Kevlar® insert of known ballistic-resistant vests. As shown, the peaks 1200 and valleys 1100 run parallel to one another and alternate across the panel 1000. As discussed above, the valleys 1100 and peaks 1200 are separated by side walls 1300. This separation can be seen in FIG. 5. Suitably, the sidewalls separate the peaks 1200 and valleys 1100 by approximately a half inch, although greater or lesser separation may be provided without departing from the spirit and intent of this application. Finally, the panel may suitably be constructed of a flexible, semi-rigid plastic that may conform to the shape of a human torso when abutted thereto.
As alluded to above in connection with FIG. 2, the panel 1000 is configured to vent heat through the spaces between (a) the vest 2000 and panel 1000 and (b) the panel 100 and a wearer's body (not shown). Comparisons between an ordinary vest (not shown) and a vest 2000 worn in connection with a panel 1000 have been conducted. When the panel 1000 is worn with a vest 2000 on a treadmill for ten minutes with a four percent grade and operating at four miles an hour, the wearer's body temperature was six to eight degrees Fahrenheit lower than when an ordinary vest (not shown) is worn by itself. The average body temperature difference for users with and without a panel 1000 was seven degrees Fahrenheit.
In addition to venting heat, the panel 1000 also contributes to the efficacy of the vest's 2000 ballistic resistance. Suitably, the contribution to ballistic resistance is provided by the semi-rigidity of the panel 1000 and the spaces created between the vest and body of the wearer by the panel 1000. In a ballistic clay test, Winchester two hundred and thirty grain (full metal jacket) ammunition was fired from ten feet away at a muzzle velocity of eight hundred and thirty five feet per second at “Second Chance Level II” body armor positioned with and without the panel 1000 between the vest and potters clay (shaped into a fourteen inch by fourteen inch by two inch torso-like form around a fifty pound punching bag). Cratering damage from the ammunition in the clay was observed to be thirty percent less when a panel 1000 was used in connection with the vest 2000.
