Definitions

  • the invention relates to a ventilation belt according to the preamble of patent claim 1.
  • Ventilation belts are often used to seal a gap between a ridge roof or ridge batten. They are usually designed as rolls, which are rolled out on a ridge or burr board.
  • Ventilators are used on the one hand to prevent the ingress of water, snow or vermin into the roof interior, on the other hand also to ventilate the space under the roof, so z. B. no condensation or fouling or mold fungus occurs.
  • Known ventilation belts do not meet all these requirements. Keeping away water, snow and vermin, they are often not sufficiently permeable to air.
  • a ventilation band which has a median strip and two side strips, wherein the side parts have openings (US 5 094 041).
  • the side parts may consist of accordion-like pieces arranged one above the other.
  • a ventilation band with a central strip and two side strips is known, the central strip has openings (GB 2 155 516 A). On the side strips are substantially perpendicular to these standing ventilation strips, which are provided with openings.
  • a ridge or burr sealing strip with ventilation function is known, which consists of a corrugated at the edges and in the middle air-permeable strips (EP 1 260 650 A2). This strip has recesses provided in its center and extending transversely to the strip, by closing the transversely extending edges.
  • a ventilation element for a roof space having a plurality of ventilation walls, which are arranged between an upper and a lower plate JP 2001 323618 A).
  • the invention has for its object to provide a ventilation belt that ensures a high exchange of air without water, snow or vermin pass through this ventilation belt.
  • the invention thus relates to a ventilation belt with at least two parallel side strips and a median strip. Ventilation belts run in parallel to the side strip, which are formed by peripherally connected walls or webs.
  • the ventilation straps can have a variety of shapes.
  • At least one ventilation duct is provided; but it is also possible to provide several ventilation ducts. By using certain materials for the ventilation belt, the restoring forces, the at least one ventilation duct when unrolling the ventilation belt can open independently. But it is also possible to effect an opening of the at least one ventilation duct by pulling on the side strips.
  • a rollable ventilation belt has ventilation openings with good ventilation properties of the plane lying below a roof skin, these ventilation openings being secured against driving rain, flying snow and the like.
  • the ingress of driving rain or snow is prevented by one or more channels made of breathable or dense materials with openings.
  • the ventilation area can be either permanently open geometrically or later, d. H. after unrolling the ventilation band, form the channel or channels.
  • different levels of ventilation can be formed, which are arranged either side by side or in the installed position offset one above the other. Each additional ventilation level is another obstacle against the ingress of driving rain. Drainage channels in all levels, except the innermost, ensure the outflow of water in the possibly existing intermediate levels to the outside.

Abstract

L'invention concerne un dispositif de ventilation comportant au moins deux bandes latérales parallèles et une bande médiane. Parallèlement aux bandes latérales s'étendent des bandes de ventilation formées par des parois ou des éléments de liaison reliés ensemble sur leur périphérie, ces bandes de ventilation pouvant présenter les formes les plus variées. Ce dispositif comprend au moins un canal de ventilation, mais il peut aussi en avoir plusieurs. L'utilisation de matériaux spécifiques dotés de force de rappel pour le dispositif de ventilation permet au canal ou aux canaux de ventilation de s'ouvrir automatiquement lorsque le dispositif de ventilation est déroulé. Mais il est également possible d'ouvrir le ou les canaux de ventilation par traction sur les bandes latérales.
