Definitions

• the invention relates to a shoe which simultaneously authorizes the protection of the human lower limbs against the explosion of explosive devices of the antipersonnel mine type and the walking or running of a person on any type of terrain.
• the current state of the art presents two types of protection of the lower limbs against the explosion of explosive devices: -i Rigid armorings (armored soles mounted on a walking shoe) which allow walking and provide protection against splinters but which are ineffective against the energy conveyed by the breath wave and the shock wave, which generate most of the destructive effects causing irreparable damage in humans and often cause amputation.
• B devices for dispersing the blast wave The dispersion is ensured by the geometric shape of the sole below called a dihedron, most often a triangular prism or a corner whose top edge formed by the two faces of the dispersion dihedral is directed towards the ground.
• dihedrons are fixed on the lower part of a shoe and have the following characteristics: • either they are incorporated in a rigid mass to allow walking, but in which case the dispersion effect is considerably reduced. Indeed, the flat surface thus created transmits almost entirely the effects of the breath wave.
• the mass coating the dihedral will be broken into pieces which may constitute (depending on the material made) piercing projectiles, a source of injury.
• the invention ⁇ aims to overcome this incompatibility between the shape of the dispersing device and the requirements for making a shoe usable in any type of circumstance and on any type of terrain.
• a dihedral type geometric shape has been integrated into a shoe, the top edge of which formed by the two faces of the dispersion dihedral is directed towards the ground and is left in the open air. This dihedral disperses most of the blast wave and the heat of the explosion.
• Stabilization elements are incorporated into the assembly to allow stabilization of the assembly relative to the ground as well as natural walking and running on all types of terrain.
• the shoe is produced in the form of a homogeneous set usable without the addition of detachable elements.
• the device according to the present invention is a shoe of the boot type, the walking sole of which is constituted by a dihedral assembly and support pins and a fire barrier.
• the set allows both an optimum dispersing effect, effective protection against heat and satisfactory use for walking and running on any type of terrain. It is also resistant to explosion and does not create piercing projectiles because it constitutes a homogeneous whole.
• the device according to the present invention preferably has the following characteristics:
• the first characteristic is intended to stabilize the shoe relative to the ground, by adding supports to the dihedral.
• These “pins”, “bers”, “pads” for support are assembled on the two faces of the dihedron so that its lower edge is perpendicular to the ground. The orientation of the pins is perpendicular to the general axis of the top edge of the dihedral.
• the second characteristic is intended to offer good support to the walker, through the particular arrangement of the support pins. These are arranged according to the anatomical supports of the foot, at the front and at the back of the shoe. The front pins will be located directly above the kick and the big toe; the rear spikes directly above the talus.
• the third characteristic is intended to allow the dihedral to fully play its role in the deviation of the breath wave. It is ensured by the small thickness of the support pins. According to the invention, the total surface of the pins represents from 15 to 35% of the surface of the sole. Thus the dihedral remains visible on at least three quarters of its lower surfaces.
• the fourth characteristic is intended to allow the dihedral to fully play its role in the deviation of the breath wave. It is ensured by the receding shape of the support pins according to FIG. 3.
• the pins are perpendicular to the top edge of the dihedral and distributed along it (characteristics 1 and 2). Therefore, when the explosion, the first obstacle encountered by the deflected blast wave will be the support pins. These will slow down the breath wave. To limit this effect, the pins must have a shape offering the least obstacle to the blast wave. A profiled shape is used for this as given in FIG. 3.
• “The fifth characteristic is intended to reinforce the deflection effect of the dihedral / spike assembly. It is ensured by the choice of composite materials of different rigidities used in their manufacture. The dihedral must be rigid to resist the breath of the explosion and therefore deflect it. The pins must be destroyed immediately.
• a sixth characteristic has the object of not creating piercing projectiles during the destruction of the pins by the breath of the explosion. It is ensured by the use of non-rigid materials in their manufacture. These materials must have a shore hardness of between 40 and 80. They can be composed of polyurethane resins or any other material having these characteristics.
• a seventh characteristic is intended to protect from the flame of the explosion. It is provided by the combination of the dispersing effect of the dihedral (characteristics 3 to 5) and a fire barrier included in the dihedral and the upper of the shoe.
• the preferred location of the fire barrier is inside the dihedral (preferably under the arch) and in the material of the upper of the shoe.
• An eighth characteristic relates to obtaining a homogeneous protective shoe. It is ensured by the integration of the upper part of the shoe, the comfort sole, the dihedral and the pins in a global assembly by means of a preferred embodiment. The result is a homogeneous structure which has excellent resistance to the blast of the explosion while allowing the dihedral to play its role because it is visible and rigid (characteristics 3 to 5) and because it remains integral with the shoe. during the explosion.
• the pins are produced one by one by cutting elastomer plates
• FIG. 1 shows in section the invention and illustrates the components of the shoe:
• a fire barrier (7) located in the dihedron of dispersion under the arch of the foot and in the upper of the shoe.
• FIG. 2 represents the invention seen in profile and illustrates its ergonomic aspects:
• the foot (4) is held in the upper of the shoe (6) and is located above the dihedral dispersion assembly (1) and support pins (5).
• the pins (5) are distributed along the dihedral and have front and rear supports.
• the rear pins are located under the talus and the front pins under the toes and the kick. This provision allows good support for the user.
• FIG. 3 represents the invention seen from below and illustrates its characteristics of dispersion of the blast wave:
• the blast wave is deflected ((2) and (3)) along the undersides of the dihedral (1).
• the receding shape of the pins (5) must offer the least resistance possible to the blast of the explosion. •
• the leading edge of the leaking volume of these pins is positioned perpendicular to the general axis of the top edge of the dihedral (8).
