Definitions

  • the invention relates to a ventilation element for the eaves-side closure of roof coverings, consisting of a stiff but flexible plastic strip, which is provided on a longitudinal wheel with teeth protruding like a comb.
  • Such a ventilation element is known from DEA-2517 458. It is intended to be attached with its plastic strip to the lowermost roof panel in such a way that the ends of the teeth lie against the underside of the roof covering panels, so that the teeth, which protrude like a comb, form a lattice structure that defines the space between the lowest roof battens and the roof covering panels completes. This lattice structure prevents animals and large foreign objects from entering the roof space without impeding ventilation of the roof space.
  • the roof covering plates have a spacing that changes from one to the other along the roof batten.
  • the ventilation element must be attached in such a way that the greatest distance from the teeth is bridged, so that the teeth are very strongly deflected in the area of the smaller distances.
  • the plastic used allows the teeth to deflect, but there is a risk that with very strong deflection, such as occurs with strongly profiled roof covering plates, the teeth will be kinked or broken off because the entire bending force occurs at the root of the teeth, i.e. on the place where the teeth merge into the edge of the continuous plastic strip. This risk exists particularly when the ventilation elements are laid at low temperatures at which the plastic necessarily loses its elasticity. Even at these temperatures, teeth can be broken later.
  • the risk is greater the thicker and therefore the more rigid the teeth.
  • the teeth must not be too thin so that they offer the desired protection against the penetration of animals and the like. In particular, it also makes little sense to make the teeth thinner than the plastic strips, because a weak point then arises precisely at the transition from the plastic strip to the teeth, at which the risk of the teeth breaking or breaking off is particularly great.
  • the invention has for its object to improve a ventilation element of the type mentioned so that the risk of kinking or breaking of the teeth is practically excluded and a high resistance to intruding animals and the like is still guaranteed.
  • the flexibility of the teeth increases towards their ends, so that they are sufficiently flexible to be able to adapt even very strongly corrugated roof covering plates.
  • the curvature of the deflected teeth runs progressively towards their ends, as a result of which both a favorable distribution of forces and high stability are achieved.
  • the stresses that arise in the material due to the bending of the teeth are distributed in such a way that no excessive forces occur precisely at the root of the teeth. Since the material is thickest here, these forces can easily be absorbed, so that there is no risk of breakage even under the most unfavorable circumstances.
  • the teeth have the same thickness at their roots as the adjacent plastic strip. As a result of the favorable distribution of forces, this plastic strip can be made thinner than previously customary.
  • the plastic strip has a thickness of approximately 1.5 mm and the teeth have a thickness of approximately 0.8 mm at their ends.
  • previously known ventilation elements generally had a thickness of approximately 2 mm. The reduced thickness in connection with the decreasing thickness of the teeth results in a not inconsiderable material saving, which is of considerable importance in today's raw material shortage, apart from the price.
  • the teeth can be in a known manner in their rest position in a common plane which forms an obtuse angle with the plane of the plastic strip. In certain cases, however, completely flat ventilation elements and ventilation elements can also be used, in which the teeth in their rest position form a right or even acute angle with the plane of the plastic strip.
  • the ventilation element shown in the drawing consists of a cross-sectionally angular plastic profile 1, which can be produced for example by extrusion.
  • One leg of the profile forms a plastic strip 2 of uniform thickness d, while the other leg forms a comb structure, the teeth 3 of which adjoin a longitudinal edge of the plastic strip 1.
  • the teeth 3 have at the transition to the plastic strip 2 the same thickness d as this plastic strip, but take in the direction of its end in it Thickness steadily decreases, so that there is only a thickness e there, which is approximately half the thickness d at its root 4.
  • the ventilation element according to the invention is attached to the eaves-side closure of roof coverings with the plastic strip 2 on the top of the lowermost roof batten facing the roof covering panels such that the teeth 3 are directed obliquely against the underside of the roof covering panels.
  • the plastic strip 2 can be provided with nail holes 5 arranged at intervals. Additional holes can allow fastening screws for roofing panels made of asbestos cement or the like to pass through without damaging the ventilation element.
  • the ventilation element can be produced in any lengths. Sections of 1 m in length have proven to be suitable in practice. It goes without saying, however, that ventilation elements of other lengths can also be used and that the ventilation element can even be assembled in the form of rolled-up strips.
  • the invention is not restricted to the exemplary embodiment shown.
  • variations in the width of the plastic strip and the length of the teeth, the width of the teeth and the distance between the teeth and the material thickness and the thickness variation of the teeth are possible. These sizes can be adapted to certain application purposes, for example to meet the requirement for an optical adjustment for certain types of roof covering or for the greatest possible universality.
