Description

       

      Schneezaun       Bekannt     sindSchneezäune    aus     Holz    und aus weit  maschigen, mit     Blechstreifen    versehenen Metalldraht  geweben, wobei die Drähte mit Kunststoff ummantelt  sein können.  



  Ebenso wurden     Naturfasergewebe    bzw.     -.matten,     netzförmig ausgebildete     Folzenstreifen    und Folien,       die        mit    Aussparungen versehen sind, zur Herstellung  von Schneezäunen verwendet.  



       Alle        diese        genannten        Schneezäune    weisen noch  erhebliche Mängel auf und     erfüllen        nicht    alle an sie  gestellten Anforderungen.  



       ,So    :zeigen     Holzschneezäune        geringe    Widerstands  fähigkeit gegen Witterungseinflüsse,     besitzen    ein  hohes Gewicht und sind     unhandlich    und schwer       transportierbar.     



  Gewebe .und Matten .aus natürlichen     Fasern    un  terliegen     ebenfalls    einem starken     Verschleiss        durch          Witterungseinflüsse.    Schneezäune aus     Metalldrähten     sind schwer ,und .sperrig und bedürfen     umfangreicher     Pflege, da sie ohnehin zum Rosten neigen. Werden  Folien für diesen     'Zweck        iverwendet,    so werden sie  infolge mangelhafter     Einreissfestigkeit        bei    mechani  scher Beanspruchung leicht zerstört.  



  Zweck der vorliegenden Erfindung ist es, obige  Nachteile eines Schneezaunes zu beseitigen. Dies  wird erfindungsgemäss dadurch erreicht, dass der  Schneezaun .aus Wirkbahnen aus     vollsynthetischen     Garnen oder Fäden besteht.  



       Als    besonders geeignet haben sich Fäden oder  Garne, die aus     ,Polyestern,        Polyacrylnitril,        Polyolefi-          nen,        Polyvinylalkohol    oder     Polyvinylchlorid    herge  stellt     sind,    erwiesen.  



  Die     gewirkten    Bahnen können in der     jeweils    vor  teilhaftesten Weise, z. B. an     Pfählen,        befestigt    oder in  Rahmen .gespannt     sein.    Der     erfindungsgemässe       Schneezaun zeichnet sich durch hervorragende Be  ständigkeit gegen     Witterungseinflüsse    aus; er besitzt  ein ,geringes Gewicht, ist dadurch sehr handlich und  leicht transportierbar .und beansprucht     bei    der Lage  rung nur einen geringen     ,Raum.     



  Die     Wirkbahnen    können mit verschiedenen  Maschen- oder     Lochgrössen        netzartig        .gearbeitet        sein,     wobei     -gegebenenfalls    einzelne durchbrochene .Stellen  dem Verwendungszweck     entsprechend        durch    Einar  beiten von Fäden ausgefüllt .sind. Dadurch     lässt    sich  die Dichte der Wirkbahnen vielseitig und aerodyna  misch günstig gestalten.     .Einige    beispielhafte Ausfüh  rungen des Schneezauns werden durch beiliegende       Zeichnung    dargestellt.  



  Zur weiteren     Verbesserung    der     Wetterfestigkeit     können die     Bahnen    .des     neuerungsgemässen    Schnee  zaunes     zusätzlich        imprägniert        .sein.  



      Snow fences Known are snow fences made of wood and woven from wide-meshed metal wire provided with sheet metal strips, the wires being coated with plastic.



  Likewise, natural fiber fabrics or mats, net-shaped foiled strips and foils, which are provided with cutouts, were used for the production of snow fences.



       All of these snow fences mentioned still have significant deficiencies and do not meet all of the requirements placed on them.



       , So: Wooden snow fences show little resistance to the weather, are heavy and unwieldy and difficult to transport.



  Fabrics .and mats. Made of natural fibers are also subject to severe wear and tear from the effects of the weather. Snow fences made of metal wires are heavy and bulky and require extensive maintenance as they tend to rust anyway. If foils are used for this purpose, they are easily destroyed due to poor tear resistance when subjected to mechanical stress.



  The purpose of the present invention is to eliminate the above disadvantages of a snow fence. This is achieved according to the invention in that the snow fence consists of active webs made from fully synthetic yarns or threads.



       Threads or yarns made from polyesters, polyacrylonitrile, polyolefins, polyvinyl alcohol or polyvinyl chloride have proven to be particularly suitable.



  The knitted webs can in each case before some kind of way, for. B. on posts, attached or .spannt in frame. The snow fence according to the invention is characterized by excellent resistance to weathering; It has a low weight, is therefore very handy and easy to transport. and only takes up a small amount of space when it comes to storage.



  The active webs can be worked like a net with different mesh or hole sizes, with individual perforated areas being filled with threads according to the intended use. This allows the density of the active webs to be designed in a versatile and aerodynamically favorable manner. Some exemplary designs of the snow fence are shown in the accompanying drawing.



  To further improve the weather resistance, the strips of the new snow fence can also be impregnated.
