Definitions

  • the invention relates to a protective cover against hailstorm, which is particularly intended for motor vehicles.
  • the protective cover is composed of several layers and is for single use.
  • One group includes air mattresses, one of which is described in the specification AT 802997. These mattresses can accomplish their task successfully, but disadvantageous is the rather complicated handling in their attachment to the vehicle, as well as their ventilation and wrinkles after use.
  • multi-layer ceilings can be classified, which have a shock-absorbing layer between two waterproof films, for example of foam rubber - see, for example, WO 9215467 or of free plastic bodies - s. AT 410428.
  • US Patent Application No. 2008174144 describes a blanket consisting of a polymer layer and an adjacent metal layer.
  • a layered protection against hailstorm is designed, wherein one of the layers is made of a relatively hard material, one of an impact-absorbing material and one of a material which adheres to the bodywork. Also in this solution, the volume of the folded ceiling is perceived as a disadvantage.
  • Superabsorbents are polymers which are capable of absorbing a multiple of their own weight of liquids, usually water or distilled water. Chemically, a superabsorbent is a copolymer of acrylic acid and sodium acrylate. Superabsorbents of this group are known by the name "FAVOR.”
  • the claimed property of the SAPs is that they attach water in enormous quantities to it at high speed, for example, WO 91/02552 states that 1 g of "FAVOR” can absorb a quantity of 6 g water within 5 s and up to 37 g water within 120 s.
  • the expanded "FAVOR" superabsorbent has an even faster absorption rate and absorbs water up to 13 times its own mass within 5 seconds, a characteristic commonly used in baby diapers and sanitary napkins the fact that the volume of the superabsorbent in contact with water also grows analogously and correspondingly rapidly remains secondary.
  • the invention has for its object to design a protective cover intended for single use, which should serve to protect the vehicles against hailstorm and which can be easily ridden as car accessories.
  • a multi-layered protective cover against the action of hail in particular for vehicles, which is formed by two outer layers, of which at least one layer is permeable to water, and between which there is a layer of superabsorber, wherein the ceiling with means provided for attachment to the vehicle.
  • a copolymer of acrylic acid and sodium acrylate can be used as an advantageous superabsorbent.
  • both outer layers are covered by a suction material, e.g. formed by a textile.
  • Adhesive tapes which are attached at least in the region of the circumference of one side of the ceiling, may serve as means for attachment to the vehicle.
  • the ceiling was spread on the roof of a car Mazda 626 and watered. After soaking, their thickness grew rapidly: after 5 seconds, the thickness was 3.3 mm, the outer layers included, after 30 s already 4.8 mm and after 120 s 7.8 mm. At the end of 5 s, ice balls of 25 to 30 g were dropped from a height of 35 m onto the covered roof. It turned out that these ice balls had not damaged the shape and surface treatment of the roof in the least after 5 seconds from soaking the ceiling.
  • the ceiling was provided with self-adhesive strips applied around the circumference of one side of the ceiling and in its axis.
  • the adhesive strips were covered with a protective film.
  • the blanket may also be provided with other means for attachment to the object to be protected, e.g. with resilient strands provided with hooks at the ends.
  • the protective cover is advantageously produced in various sizes and thicknesses and vacuum-packed in a film.
  • the ceiling according to the invention can be used in addition to cars for the protection of other movable and immovable objects, such as construction and agricultural machinery or glasshouses and others
  • the development in the field of superabsorbents is progressing very rapidly and new substances with even better properties are being developed.
  • the scope of the present invention is not limited only to the superabsorbent FAVOR and the pulp sheet recited in the specification and claims.
  • the ceiling according to the invention was designed primarily as part of the car equipment.
  • the operator removes the blanket from the vacuum package, partially widening it, exposing the adhesive tabs on one of the shorter sides and thereby securing the blanket to the front or rear bumper. Then he pulls the blanket over the car and tucks it to the other bumper. Then the ceiling is glued with its longer sides to the thresholds or wheels. Before the hailstorm comes, the blanket absorbs the rainwater, increasing in volume and mass, ready to withstand the hailstorm. It is also possible to water the ceiling in advance, preferably on the horizontal and sloping surfaces. After no more danger, the ceiling is removed and disposed of environmentally friendly.
