The field of the present disclosure relates generally to body armor and ballistic carriers, and more specifically to a heat dispersion system for use with ballistic carriers for carrying ballistic panels and/or plates and ballistic carriers having the heat dispersion system integrated therein.
Ballistic carriers are tactical protective garments designed to carry ballistic panels such that the ballistic carrier and panels protect a wearer from bodily injury from attacks and other hazards. One of the most common ballistic carriers is a vest, commonly referred to as a “bullet proof vest.” The ballistic carriers typically have pockets for inserting body armor to protect the wearer from ballistics, such as bullets and explosive fragments. There are two main types of body armor: hard-plate body armor (often referred to as “armored plates”) which can protect a wearer from very high energy ballistics such as rifle rounds; and soft (non-plated) body armor (often referred to as “armored panels”) which can protect a wearer from handgun rounds and small explosive fragments.
In view of their functions as protective gear and to ensure durability, ballistic carriers are made of heavy duty, strong materials capable of supporting the body armor and surviving harsh conditions and rigorous duty cycles. As a result, the weight, profile and materials used of ballistic carriers and body armor carried therein, these tactical garments are high thermal insulators which trap body heat. Combined with the environments and physical activity often associated with their use, the person wearing such tactical armor often experiences excess heat, sweat, and associated discomfort, or even heat exhaustion and dehydration.
Some devices for alleviating the heat and perspiration caused by wearing ballistic carriers have been previously disclosed. For example, air circulation devices that blow a pressurized volume of air using electric fans through the ballistic carrier have been described. However, such devices are bulky and inefficient, and require a source of electric power. Passive garments worn under the ballistic carrier have also been disclosed, but such garments are relatively ineffective, and provide at most a small amount of relief from perspiration via wicking wetness from the wearer's skin and no cooling effect. Accordingly, there is a need for an improved design for providing cooling effects for tactical garments such as ballistic carriers like bullet proof vests and other tactical and protective garments.
Disclosed herein is a ballistic carrier for carrying ballistic armor and having a heat dispersion system which utilizes an innovative multi-layer thermal panel having a high thermal conductivity to transfer heat away from between the ballistic carrier and the wearer's body to the exterior side of the ballistic armor. The ballistic carrier may be worn and used with, or without, ballistic panels inserted into the carrier.
Accordingly, in one disclosed embodiment, a ballistic carrier comprises a carrier configured to be worn on a body of a person or other animal, such as a dog, horse, especially animals used in law enforcement and. The carrier has a first body panel for covering a part of a wearer's body. As used herein, the term “wearer” refers to any animal, such as a person, or other animal such as a dog, horse, etc. For example, the first body panel may be a front portion configured to cover a front of the wearer, such as the front portion of a ballistic vest. The first body panel has an inner panel configured to rest against the body and an outer panel opposing the inner panel and being external to the inner panel. The inner panel and outer panel are configured to form a pocket or housing for holding a ballistic panel. For example, the ballistic panel may be body armor such as an armored plate or armored panel. The inner panel has an inside surface which faces the body of the wearer and an outside surface which faces away from the body and forms an inner side of the pocket. The outer panel has an outside surface which faces away from the body, and an inside surface which faces toward the body and forms an outer side of the pocket opposing the inner side of the pocket. The pocket has an opening for inserting the ballistic panel and a closure for closing the opening. For instance, the closure may be a length of mating hook and loop fasteners, snaps, buttons, or the like. In another aspect, the opening is on a lateral side of the ballistic carrier (i.e., not on the bottom or top of the carrier) such that a ballistic panel is inserted into the pocket from the side.
A thermal panel is attached to the first body panel within the pocket. The thermal panel comprises a first layer of heat absorbing textile comprising phase change molecules (PCMs), and a second layer applied to, and covering, the first layer. The second layer comprises a heat transfer film comprising oriented graphite with a high thermal conductivity. The thermal panel has a first thermal panel portion attached to the outside surface of the inner panel with the heat absorbing textile side of the thermal panel against the outside surface of the inner panel. The first thermal panel portion is positioned such that it is on an inside of a ballistic panel inserted into the pocket. The first thermal panel portion covers a substantial part of the outside surface of the inner panel. As used herein, the term “substantial part” means at least 75% or more.
The thermal panel also bends around proximate to an edge of the pocket and has a second thermal panel portion which extends along a portion of the inside surface of the outer panel such that the second thermal panel portion is on an outside of a ballistic panel inserted into the pocket. In one aspect, the second thermal panel portion extends along at least 10%, or at least 20%, or at least 25%, or at least 30%, or at least 40%, or at least 50% of the full length of the pocket or of the inside surface of the outer panel, or of the full length of a ballistic panel to be inserted into the pocket. In this way, the thermal panel absorbs heat expelled by the body, dissipates the heat, and transports the heat from the first thermal panel portion close to the body to the second thermal panel portion positioned proximate the outer panel of the pocket, i.e., on an outside of a ballistic panel inserted into the pocket.
Accordingly, the ballistic carrier, when worn on a body, provides a cooling effect and relief from building up body heat within the carrier by transferring heat away from the interior of the ballistic carrier and dissipating the heat on the outside on the outside of the carrier and into the ambient environment.
In another aspect, the thermal panel may further include a backing layer applied to, and covering, the other side of the heat transfer film opposite the heat absorbing textile. The backing layer may comprise a fabric which provides a good surface for bonding the thermal panel to other materials.
In still another aspect, the inner panel may comprise a mesh fabric. In yet another aspect, the inner panel may further comprise a heat spreading layer disposed on an inside surface of the mesh fabric facing the body side of the carrier. The heat spreading layer comprises a fabric having a mesh of PCMs applied onto the fabric to absorb heat from expelled from the body and spread the heat over the area of the fabric. The heat dissipated over the heat spreading layer then migrates to the thermal panel, and is transported through the thermal panel as described above. Alternatively, the inner panel may comprise the heat spreading layer without a mesh fabric.
In yet another aspect, the outer panel may comprise a mesh fabric. The mesh fabric may be the same or similar to the mesh fabric of the inner panel. For example, the mesh fabric forming the outer panel may form at least a portion of the outer-most surface of the ballistic carrier. In yet another aspect, the outer panel may further comprise a heat spreading layer disposed on an inside surface of the mesh fabric facing the body side of the carrier. The heat spreading layer may be the same or similar material as the heat spreading layer on the inner panel. In other aspects, additional materials, layers and/or devices may be attached to an outer surface of the mesh fabric outer panel, such as hook and/or loop fasteners, “PALS” or “MOLLE” carrying systems, straps, etc.
In another aspect, the ballistic carrier is a torso worn garment, such as a vest, jacket, or the like, and the first body panel is a front portion of the garment configured to cover the front torso of the wearer. In yet another aspect, the ballistic carrier further comprises a second body panel which is a back portion of the garment configured to cover the back torso of the wearer. The second body panel is attached to the first body panel by a pair of shoulder straps. The carrier may also have side straps for attaching a lower portion of the first body panel to a lower portion of the second body panel. The side straps may be detachably fastenable using hook and loop fasteners, snaps, buttons, etc.
In still another aspect, the second body panel may also be configured to carry a back ballistic panel and also to have the heat dispersion system like the first body panel. The heat dispersion system for the second body panel may be the same or different from the first body panel, and may include any one or more of the aspects and features of the heat dispersion system described herein.
The opening for inserting the front ballistic panel may be on the side of the first body panel ballistic carrier and is oriented vertically with the opening. Similarly, the opening for inserting the back ballistic panel is on the side of the first body panel ballistic carrier and is oriented vertically with the opening. In another aspect, the opening for inserting the front ballistic panel may be on the bottom side of the first body panel ballistic carrier such that the panel is inserted by sliding the panel upward into the respective pocket of the carrier. Similarly, the opening for inserting the back ballistic panel may be on the bottom side of the first body panel ballistic carrier such that the panel is inserted by sliding the panel upward into the respective pocket of the carrier.
In still another aspect, the ballistic carrier may include a front ballistic panel inserted into the pocket of the first body panel, and/or a back ballistic panel inserted into the second body panel, if one. The ballistic panel(s) may be any suitable ballistic panel, such as an armored plate, an armored panel, or the like.
In still another aspect, the ballistic carrier may further include an undergarment configured to be worn by a wearer such that an outer surface of the undergarment contacts the interior section of the first body panel and/or the interior section of the second body panel. The undergarment may comprise phase change material molecules to absorb and spread body heat. For example, the undergarment may function as the heat spreading layer described above. In such case, the outer surface of the undergarment contacts the inside surface of the interior section, which may be an interior mesh layer of the carrier.

The present specification is directed to a ballistic carrier for carrying ballistic armor having a heat dispersion system. The heat dispersion system includes multi-layer thermal panel having a high thermal conductivity to conduct heat away from between the ballistic carrier and the wearer's body to the exterior side of the ballistic armor and away from the wearer into the ambient environment. Accordingly, the ballistic carrier delivers a cooling effect, preventing the build-up of body heat and sweat. It achieves this result by transferring heat away from between the wearer's body and the ballistic carrier and transmitting the heat to the outside, effectively releasing the heat into the surrounding environment.

The front body panel comprises an inner panel 114a and an outer panel 116a which are attached to each other around their respective periphery edges such that a pocket 110a for holding a front ballistic panel 112a is formed between the inner panel 114a and the outer panel 116a, as best shown in
The pocket 110a has an opening 144a for inserting the front ballistic panel 112a into the pocket 110a. The opening 144a is on the side edge of the front body panel 102 and is oriented vertically along the edge of the front body panel (the opening 144a can be on either side of the front body panel 102). The opening 144a is formed by a portion of the opposing side edges of the inner panel 114a and the outer panel 116a which are detachably fastened together by a closure 146a. The closure 146a comprises mating hook and loop fasteners extending along a length of the side edges of the inner panel 114 and outer panel 116a. The closure 146a may comprise any other suitable fasteners such as buttons, snaps, ties, clips, or the like.
A thermal panel 126a is attached to the first body panel 102 within the pocket 110a adjacent to, and on the outside of, the inner panel 114a. As one example, the thermal panel 126a may be attached to the inner panel 114a such as by being sewn, bonded, or otherwise suitably attached. The thermal panel 126a has a first thermal panel portion 128a which extends from proximate the top of the pocket 110a and inner panel 114a, downward to proximate the bottom edge of the pocket 110a and inner panel 114a, such that the first thermal panel portion 128a is configured to be positioned on the inside of the ballistic panel 112a. The first thermal panel portion 128a covers a substantial part (i.e., at least 75% or more) of the outside surface 120a of the inner panel 114a. Alternatively, the first thermal panel portion 128a may cover at least 70% or more, or 65% or more, or 55% or more of the outside surface 120a of the inner panel 114a.
The thermal panel 126a then bends around the bottom of the pocket 110a to towards the front of the pocket 110a, and then a second thermal panel portion 130a of the thermal panel 126a, extends upward along the inside surface 112a of the outer panel 116a such that the second thermal panel portion 130a is configured to be positioned on the outside of the ballistic panel 112a. There is a space between the first thermal panel portion 128a and the second thermal panel portion 130a for inserting the ballistic panel 112a. The second thermal panel portion 130a extends along a length of the inside surface 112a of the outer panel 116 and a length of the ballistic panel 126a. For example, the second thermal panel portion 130a extends along at least 10%, or at least 20%, or at least 25%, or at least 30%, or at least 40%, or at least 50%: of the full length of the inside surface 122a of the outer panel 116a; or of the full length of the pocket 110a; or of the full length of the ballistic panel 112a. The second thermal panel portion 130a expels heat absorbed by the first thermal panel portion 128a and conducted by and along the thermal panel to the second thermal panel portion 130a. In other words, the first thermal panel portion 128a absorbs heat expelled by the body, dissipates the heat, and conducts the heat from the first thermal panel portion 128a close to the body and to the inside of the ballistic panel 112a to the second thermal panel portion 130a adjacent the outer panel 116a and to the outside of the ballistic panel 112a. As a result, the thermal panel 126a effectively transfers body heat around the high thermal insulating ballistic panel 112a and expels the heat into the ambient environment. The transfer of body heat by the thermal panel 126a provides a cooling effect to the body 152 and prevents body heat from building up within the carrier 100 by conducting heat away for the interior of the ballistic carrier proximate the body, dissipating the heat to the outside of the carrier 100 and into surrounding air. The second thermal panel portion 130a may be unattached or loose such that the thermal panel 126a can be wrapped around the bottom end of the front ballistic panel 112a. Alternatively, the second thermal panel portion 130a can be attached to the outer panel 116a by being sewn, bonded, or otherwise suitably attached.

The use and functionality of the ballistic carrier system 100 will now be described. Typically, the front and back ballistic panels 112a, 112b are first inserted into the front body panel 102 and rear body panel 104, respectively. For example, the front ballistic panel 112a is inserted into the pocket 110a through the opening 144a by unfastening the closure 146a, and sliding the front ballistic panel 112a into the pocket 110a such ballistic panel 112a is between the first and second thermal panel portions 128a, 130a, with the first thermal panel portion 128a directly to the inside of the front ballistic panel 112a and the second thermal panel portion 130a is directly to the outside of the front ballistic panel 112a. The closure 146a is then fastened to close the opening 144a. Similarly, the back ballistic panel 112b is inserted into the pocket 110b through the opening 144b by unfastening the closure 146b, and sliding the back ballistic panel 112b into the pocket 110b such that back ballistic panel 112b is between the first and second thermal panel portions 128b, 130b, with the first thermal panel portion 128b directly to the inside of the back ballistic panel 112b and the second thermal panel portion 130b is directly to the outside of the back ballistic panel 112b. The ballistic carrier 100 is now ready to be donned by the person 150.
The person 150 may first put on the undergarment 160 to provide additional thermal dissipation. Then, with the shoulder straps 106 attached to both the front body panel 102 and the back body panel 104, and the side straps 107 unfastened, the carrier 100 is put on over the person's head with such that the shoulder straps 106 are positioned on the shoulders of the person's body 152 with the front body panel 102 resting on and covering the front torso and the back body panel 102 resting on and covering the back torso. The side straps 107 are then fastened.
The heat dispersion system functions to absorb and transfer body heat away from the body 152. Heat expelled by the body is first absorbed and spread over the area by the undergarment 160, if worn by the person 150. For the front body panel 102, The heat is then absorbed by the inner heat spreading layer 138a and dispersed over the area of the inner heat spreading layer 138. The heat then migrates outward and is absorbed by the first thermal panel portion 128a of the thermal panel 126a. The thermal panel 126a disperses the heat in the thermal panel 126a and transfers the heat along the length of the thermal panel, around the front ballistic panel 112a to the second thermal penal portion 130a in front of the front ballistic panel 112a. The heat then transfers from the second thermal panel portion through the outer panel 116a (which may be a mesh fabric) and into the air in the surrounding environment. The dissipation of body heat by the back body panel 104 is the same. Accordingly, the ballistic carrier 100 provides a cooling effect and relief from building up body heat within the carrier 100 by transferring heat away from the interior of the ballistic carrier 100 and dissipating the heat on the outside on the outside of the carrier 100 and into the ambient environment.
