Dosavadni stav technikyCurrent state of the art
Znâmâ ochrannâ obuv proti ùcinkùm nâslapnÿch min podle patentu CZ 291156 B6 a zverejnené prihlâsky WO 03037125 A1 je tvorena svrskem s napinaci stélkou a k nemu prostrednictvim soustavy alespon dvou mezipodesvi pripojenou podrâzkou. Napinaci stélka, pnpadne alespon jedna z mezipodesvi jsou tvoreny kompozitem na bâzi alespon tri vrstev textilie z paraaramidového vlâkna fixovanÿch v polymerni matrici. Svrsek mâ mezi podsivkou a vrchovÿm materiâlem ulozenou alespon jednu vrstvu vÿztuzné textilie na bâzi paraaramidového vlâkna, pricemz podsivka s temito mezivrstvami je v nâslapné câsti obuvi prekryta alespon tremi vrstvami paraaramidové tkaniny, které maji své po obvodu delené okrajové câsti prehnuty smerem vzhùru a jsou orientovâny tak, ze obvodové spoje prehnutÿch okrajovÿch câsti jsou u jednotlivÿch vrstev navzâjem posunuty a preplâtovâny. v oblasti spice, paty a/nebo stélky jsou ve strukture obuvi zabudovâny ochranné segmenty na bâzi kompozitu tvoreného alespon jednou vrstvou paraaramidové textilie fixovanou v polymerni matrici. Spodkovâ câst obuvi obsahuje soustavu mezipodesvi a k nim pripojenou podrâzku. Pri tom je alespon jedna z mezipodesvi horni câsti soustavy zhotovena z kompozitniho materiâlu a alespon jedna v mezipodesvi spodni câsti soustavy z lehceného polymerniho materiâlu. Tato skladba spodkové câsti se ale v praxi ukâzala jako ne zcela optimâlni z hlediska ùtlumu energie vÿbuchu.The well-known protective footwear against the effects of landmines according to patent CZ 291156 B6 and published application WO 03037125 A1 consists of an upper with a tensioning insole and a brace connected to it through a system of at least two midsoles. The tension insoles, or at least one of the midsoles, are made of a composite based on at least three layers of para-aramid fiber fabric fixed in a polymer matrix. The upper has at least one layer of reinforced fabric based on para-aramid fiber placed between the lining and the upper material, while the lining with these interlayers is covered in the non-footed part of the shoe with at least three layers of para-aramid fabric, which have their circumferentially divided edge parts folded upwards and oriented as follows , from the circumferential joint of the folded edge parts are shifted and overlapped with each other in the individual layers. in the area of the spike, heel and/or insole, protective segments are built into the structure of the shoe based on a composite consisting of at least one layer of para-aramid fabric fixed in a polymer matrix. The lower part of the shoe contains the midsole system and the insole connected to them. At the same time, at least one of the midsoles of the upper part of the system is made of composite material, and at least one of the midsoles of the lower part of the system is made of lightweight polymer material. However, in practice, this composition of the lower part turned out to be not quite optimal from the point of view of reducing the energy of the explosion.
Obdobnÿ problém je i u dalsiho reseni podle zverejnené prihlâsky vynâlezu CZ 2009-297 A3 a zverejnené prihlâsky WO 2010/130231 A1, kde svrsek mâ mezi podsivkou a vrchovÿm materiâlem ulozenu a/nebo vlepenu alespon jednu vrstvu vÿztuzné textilie na bâzi paraaramidového vlâkna a napinaci stélka a/nebo alespon jedna z mezipodesvi jsou na bâzi kompozitu alespon tri vrstev textilie z paraaramidového vlâkna fixovanÿch v mezivrstvâch polymemi matrice. Hustota materiâlù jednotlivÿch dilcù v této soustave mezipodesvi a podesve spodkové câsti obuvi se navzâjem lisi tak, ze rozdil v hustote pouzitÿch kompozitnich materiâlù sousedicich mezipodesvi, resp. podesve, i rozdil v hustote sousedicich vrstev ve vicevrstvé strukture prislusné mezipodesve musi bÿt minimâlne 0,1 g/cm3. Tvrdost materiâlù jednotlivÿch dilcù v soustave mezipodesvi a podesve spodkové câsti obuvi se navzâjem lisi tak, ze rozdil v tvrdosti kompozitnich materiâlù sousedicich mezipodesvi, resp. podesve, i rozdil v tvrdosti sousedicich vrstev ve vicevrstvé strukture prislusné mezipodesve musi bÿt minimâlne 1 ShA. Tlousfka kazdé jednotlivé mezipodesve i podesve musi bÿt minimâlne 10 mm a celkovâ tlousfka soustavy mezipodesvi a podesve spodkové câsti obuvi musi bÿt minimâlne 30 mm. Je zrejmé, ze cilem této vicevrstvé konstrukce spodkové câsti mela bÿt zlepsenâ odolnost spodku obuvi proti ùcinkùm vÿbuchu nâslapné miny. Ani tato skladba spodkové câsti se ale v praxi neukâzala jako optimâlni z hlediska ùtlumu energie vÿbuchu.A similar problem exists in another solution according to the published invention application CZ 2009-297 A3 and the published application WO 2010/130231 A1, where the upper has at least one layer of reinforced fabric based on para-aramid fiber and a tension insole placed and/or glued between the lining and the upper material and /or at least one of the midsoles is based on a composite of at least three layers of para-aramid fiber fabric fixed in the interlayers of a polymer matrix. The density of the materials of the individual parts in this system of the midsole and the sole of the lower part of the shoe differ from each other in such a way that the density of the composite materials used in the neighboring midsoles, or sole, as well as the difference in density of adjacent layers in the multi-layer structure of the respective midsole must be at least 0.1 g/cm 3 . The hardness of the materials of the individual parts in the system of the midsole and the sole of the lower part of the shoe differ from each other in such a way that the hardness of the composite materials of the neighboring midsoles, or sole, and the difference in hardness of adjacent layers in the multi-layer structure of the respective midsole must be at least 1 ShA. The thickness of each individual midsole and sole must be at least 10 mm, and the total thickness of the system of the midsole and the sole of the lower part of the shoe must be at least 30 mm. It is obvious that the aim of this multi-layer construction of the lower part was to improve the resistance of the bottom of the shoe against the effects of a landmine explosion. Even this composition of the lower part, however, did not prove to be optimal in terms of detonation of the explosion energy.
