Abstract
Description
Obutev zaščitena z mikroperforirano vodo odbojno prevlekoFootwear protected by micro perforated water repellent coating
Predmet izuma je obutev, ki je zaščitena pred vdorom vode v notranjost z vodo odbojno plastjo, ki je mehansko ali kako drugače obdelana tako, da je vodo odbojna plast preluknjana z vrsto zelo majhnih luknjic. Izum spada v razred A43B23/06 mednarodne patentne klasifikacije.The object of the invention is footwear, which is protected from the penetration of water into the interior by a water-repellent layer, which is mechanically or otherwise treated in such a way that the water-repellent layer is punctured by a series of very small holes. The invention belongs to Class A43B23 / 06 of the International Patent Classification.
Tehnični problem, ki ga predložena konstrukcija obutve rešuje, je zaščita pred vdorom vode v obutev in hkrati prenos vodne pare iz notranjosti obutve v prostor.A technical problem to be solved by the proposed footwear construction is protection against the ingress of water into the footwear and at the same time the transfer of water vapor from the inside of the footwear to the room.
Znano je, da človeško telo moramo zaščititi pred prenizkimi 15 temperaturami, posebej še pred vplivom atmosferilij kot sta dež in sneg. Zato zaščitimo stopalo z obutvijo, ki je nepropustna za vodo. Taka poznana rešitev ima slabo lastnost, da ne omogoča dihanja stopala in zato povzroča neugoden občutek in prekomerno potenje. Obstajajo različne rešitve opisanega problema z različnimi polprepustnimi membranami, ki preprečujejo vdor vode v obutev in obenem omogočajo omejen pretok zraka in vodne pare. Slabost teh rešitev je v dejstvu, da za zaščito pred mehanskimi poškodbami potrebujejo zunanjo zaščitno plast, ki pa ni nepropustna in je običajno v obliki tkanine ali usnja. Tako tkanina kot usnje absorbirata vodo in s tem povečata svojo maso, kar pomeni večji napor pri uporabi obutve in tudi zmanjšano toplotno izolacijo. Prav tako je količnik trenja med tkanino in snegom, zaradi hrapavosti površine tkanine, večji kot med snegom in povsem gladko površino, kot jo ima na primer vodo odbojni material. Med gibanjem v naravi v kateremkoli letnem času smo večkrat izpostavljeni vplivu vode ali snega tako, da prekrije večjo površino čevlja. Gladka površina omogoča hitrejši zdrs snega ali vode s čevlja in s tem krajšo izpostavljenost materiala čevlja vodi. Zmanjšanje časa, ko je obutev prekrit z vodo ali snegom pa pomeni zmanjšanje možnosti prodora vode v obutev in povečanje časa, ko obutev lahko diha.It is well known that the human body must be protected from too low a temperature of 15, especially against the effects of atmospheres such as rain and snow. This is why we protect the foot with waterproof footwear. Such a well-known solution has the bad property of not allowing the foot to breathe and therefore causes an unpleasant sensation and excessive sweating. There are various solutions to the problem described with different semi-permeable membranes that prevent water from entering the footwear while allowing limited air and water vapor flow. The disadvantage of these solutions is that they require an external protective layer to protect against mechanical damage, which is not impermeable and usually in the form of fabric or leather. Both the fabric and the leather absorb water, thereby increasing its mass, which means more effort in the use of footwear and also reduced thermal insulation. Also, due to the roughness of the fabric surface, the coefficient of friction between the fabric and the snow is greater than that between the snow and a completely smoother surface than, for example, the water-repellent material. During movement in the wild at any time of the year, we are repeatedly exposed to the effects of water or snow by covering a larger surface of the shoe. Smooth surface allows faster removal of snow or water from the shoe and thus shorter exposure of the shoe material to water. Reducing the time when footwear is covered with water or snow means reducing the possibility of water penetrating the footwear and increasing the time when footwear can breathe.
Izum bomo podrobneje obrazložili na osnovi izvedbenega primera in slik od katerih kaže:The invention will be explained in more detail on the basis of an embodiment and illustrations of which:
Slika 1 obutev, sestvljena iz zgornjega dela 1 in podplata 2, katerega celoten zgornji del 1 je izdelan iz mikroperforiranega materiala 3Figure 1 Footwear, consisting of the upper part 1 and the sole 2, the entire upper part of which is made of micro-perforated material 3
Slika 2 obutev, katerega zgornji del 1 je samo delno izdelan iz mikroperforiranega materiala 3, del pa iz vodo odbojnega materiala 7Figure 2 footwear, the upper part of which is only partly made of micro-perforated material 3 and the part is made of water-repellent material 7

Slika 4 shematski prikaz mikroperforiranega materiala 3 in razporeditev luknjic mikroperforacije 4.Figure 4 is a schematic view of the micro perforated material 3 and the arrangement of the holes of the microperforated 4.
Konstrukcijska rešitev izdelave obutve iz mikroperforiranega materiala v obliki majhnih luknjic, razporejenih po površini materiala, ki so po premeru bistveno manjše od skupne debeline materiala. Mikroperforiran material je najmanj dvoslojni, sestavljen iz zunanjega gladkega in vodo odbojnega sloja 5 in notranjega ojačitvenega sloja 6, ki je bodisi tkan ali netkan, pri tem, da sta sloja spojena tako, da ostane zunanji sloj na zunanji strani gladek. Sama mikroperforacija je izvedena s majhnimi luknjicami, ki v premeru niso večje od debeline materiala zunanjega gladkega sloja, prednostno manj kot 0.1 mm premera in so izdelane dovolj na gosto, da omogočijo zadostno dihanje materiala, prednostno več kot 10 luknjic na cm2.Design solution for the production of footwear made of micro-perforated material in the form of small holes arranged over the surface of the material, which are substantially smaller in diameter than the total thickness of the material. The micro-perforated material is at least two-layer, consisting of an outer smooth and water-repellent layer 5 and an inner reinforcement layer 6, either woven or non-woven, with the two layers joined together so that the outer layer remains smooth on the outside. The micro perforation itself is made with small holes no larger than the thickness of the outer smooth layer material, preferably less than 0.1 mm in diameter, and made sufficiently dense to allow sufficient material to breathe, preferably more than 10 holes per cm 2 .
