Definitions

  • the invention involves special protective boots against the effects of land mines with optimized design components, while the optimization helps the human body protective function to be of maximum efficiency, especially with respect to the lower limbs.
  • the currently manufactured anti-infantry land mine prototypes are classified as weapons of mass of destruction and with their effectivity these are not much behind nuclear, chemical or biological weapons. It is known that due to their character mines affect mainly civilians frequently long after the conclusion of an armed conflict. It is estimated that today there are over a hundred million land mines buried underground, i.e. approx one mine for every fifty people on Earth. In addition these mines are often developed in a way that they do not directly kill, but only to cause painful injuries with permanent consequences. With respect to the above stated facts the effort to keep developing and optimizing special protective boots to protect a person exposed to the dangerous effects of landmines as much as possible is understandable.
  • the next solution present the same difficulty, although not to such an extent, and this being the protective platform, which is formed by a special impact deflector - deflecting prism, stored under a groovy sole from sponge-like polyurethane.
  • the walking platform surface is fitted with slip proof surface.
  • the binding is mounted on the platform - a shell that reaches above the ankle, provides support while you walk and protects from shrapnel. This binding is then used to mount an ordinary boot via belts.
  • the impact deflector is placed along the entire length and width of the foot. It has a conical shape with a top angle of less than 90° and is placed in such a way that its peak is pointing to the stepping side of the platform.
  • the deflector can either be full or hollow, manufactured from metal or plastic composites.
  • the recommended design offers a pipe-like plastic composite wrapped in a cloth.
  • the above stated design (protective platform) is categorized as special protective equipment, which well protects the human body from the effects of landmines, but at the same time it also quite significantly restricts the natural striding motion, especially during running, jumping and so on.
  • a protective boot type to date according to CZ patent No. 291156 and the PCT application WO 03037125 is formed by an upper with an insole and at least two middle soles connect the sole here.
  • the essence of the invention is that the insole and/or at least one of the middle soles are made from a composite material based on a at least three layers of para-aramid textile fixed in a polymer matrix, the upper has at least one layer of para-aramid fiber based reinforcing textile placed between the lining and the top material, while the lining between these middle layers in the stepping part of the boot is covered with at least three layers of para-aramid textiles, which have their perimeter border segments split and folded upward and are oriented in a way that the perimeter bonds in the folded border segments on the individual layers are mutually shifted and overlapped.
  • Composite based protective segments formed by at least one layer of para-aramid textile fixed in a polymer matrix are built into the area of the tip, heel and/or the insole boot structure.
  • the bottom segment of the boot contains a system of middle soles and a sole connected to these. While at least one of the middle soles of the upper part of the system is made of composite material, at least one of the middle soles of the bottom section of the system is then made from a sponge- like polymer material.
  • the invention for the structure of the sole includes at least a single fixed layer of para-aramid textile.
  • the protective boots can furthermore be fitted with an insole insert, where its benefit is the composite material based on at least a single layer of para-aramid textile fixed in a polymer matrix with air fillings.
  • the benefit of this protective boot lies it the effort to balance the requirements on the boot's protective effect, weight and flexibility of the boot during walking, running, possibly jumping and the life span of the boot while worn.
  • the entire protective segment of the boot is designed as a compact unit based on an overall composite material, which has layers of para-aramid fiber based textiles fixed and mutually connected in a polymer matrix without any foreign element — the boot does not contain any metal components.
  • the blast protective boots contribute to the solution of this issue with their optimized design elements according to the invention, formed by a shoe upper with an insole and connected to this we have the system in the bottom segment of the boot based on at least two middle soles and a sole.
  • the essence of the invention lies in the fact that the shoe upper has at least a single layer of para-aramid fiber based reinforcing textile inserted and/or cemented in between the lining and the top material, the tension insole and/or at least one of the middle soles is based on composite of sandwich structures made of at least three layers of para-aramid fiber textile fixed in the middle layers of polymer matrix and the entire bottom segment of the boot is formed by a sandwich system.
  • Material hardness of the individual parts of the system of middle soles and sole in the bottom segment of the boot differ in a way where the difference in hardness of the composite materials in the adjacent middle soles, or more precisely the sole, and the difference in hardness of the adjacent layers in the sandwich multilayer structure of the said middle sole must be at least 1 ShA. Thickness of each individual middle sole and the sole of the sandwich system must be at least 10 mm and the total thickness of the middle soles and sole system in the bottom segment of the boot must be at least 30 mm.

It is furthermore of benefit that at least one of the middle soles is fitted with carved or pressed grooves.
  • the structure of the tension insole contains a composite based protective insole segment built in or fixed on it and this is formed by at least three layers of para-aramid textile fixed in a polymer matrix.
  • Para-aramid textile in the structure of the above stated boot component can generally be Kevlar, Twaron or ballistic textile.
  • the polymer matrix is then an elastomer mixture based matrix, especially of rubber or pol yurethane.
  • this polymer matrix can also be thermoplastic based, this especially of an Ethylene vinyl acetate copolymer.
  • the middle sole of the upper part of the middle soles system can also be made directly from a composite material with para-aramid textile content.
  • the middle sole of the bottom part of the sandwich system is made of a sponge-like based elastomer material, possibly from material based on sponge-like polyolefin, especially of copolymer of Ethylene vinyl acetate.
  • the sole of the protective boot can also be fitted with an air chamber in the area of the heel.
  • the main benefit of the blast protective boots according to the invention is given by the unique properties of the sole's sandwich structure, which consists of 2 layers of materials with various densities in combination with a reinforcing para-aramid fiber (ballistic) based material.
  • the primary pressure wave caused by the explosion of the mine is broken up and deflected upon its passing through the transitional plane between the two materials having various density and hardness. This therefore forms secondary counter waves, which generate force against the primary pressure wave.
  • the layered sandwich material is at the same time being separated by gradual peeling of the individual layers and therefore absorbs the energy of the primary wave.
  • the ballistic material in the sandwich dampens the primary wave and at the same time it works as an anti perforation protection, meaning it prevents shrapnel penetration.
