Definitions

  • the present invention relates to a cellular plastic material, more precisely such a material that can be used, for example, as a flotation material in flotation devices, such as flotation jackets, boating jackets and similar personal safety devices, or as an impact-absorbent material in sportswear and similar. Naturally, its use is not limited to only these applications.
  • life jackets are known and used when moving on water.
  • life jackets the two most common basic types being life jackets and the somewhat lighter boating jackets.
  • the general principle of the aforesaid rescue devices is that they have a basic form of a jacket secured around the upper body, which supports a person who falls into the water.
  • life jackets proper there is often also a section that turns an unconscious person onto his back in the water and holds his head above water, preventing drowning.
  • a general feature of all jackets is that contained within various kinds of supporting fabrics there is a flotation material, intended to provide the actual support, as it is essentially impermeable to water and lighter than water.
  • the conventional material is a sheet of closed-cell plastic, located within a compartment in the structure of the jacket.
  • Material of the flotation type described above is used in a great deal of sportswear as an impact-absorbing material.
  • cellular plastic sheets are used in ice-hockey players' trousers and other equipment, to soften the impact of the puck or blows, collisions and similar caused by other players.
  • Such equipment is often extremely sweaty, because the impact protection material does not breathe, nor can it be made from a material with a basic structure permitting the passage of air, as then it would also absorb sweat, making its use difficult in that respect.
  • This invention is intended to alleviate the non-breathing construction of rescue devices, sportswear and similar, making them more comfortable to use, and, especially in the case of rescue devices, also making their use on the water more likely.
  • a further purpose is to create solutions that save material compared to the state of the art.
  • Figure 1 shows the invention in the normal position
  • Figure 2 shows the invention in the opened position.
  • figures 1 and 2 show a material according to the invention, made for flotation, impact-absorption, thermal insulation or other similar purposes, which is here in the form of a sheet-like piece 1.
  • the thickness of the material is always selected according to the use, the raw material being mainly closed-cell plastic, so that it does not essentially absorb moisture, but which has excellent flotation properties, the hardness of the material being selected to also meet the criteria required for impact resistance.
  • Thermal insulation properties can also be selected by the choice of material for individual cases.
  • the material sheet 1 shown in figure 1 has cuts 2 in it, made, for example, as in figure 1 , i.e., as essentially parallel cuts, arranged to lie partly between each other in adjacent rows.
  • the cuts can be arranged differently, as in figure 2, allowing the material to be made to breathe and ventilate.
  • the cuts are made through the material, so that at each cut there is always also a through hole. Even after the cuts are made, the material retains its external character.
  • Figure 2 shows how the material described in figure 1 above is made into precisely a breathing substance, in a way that saves material. If the material in figure 1 is pulled in a transverse direction to the cuts, the material opens at the cuts, forming the cuts 2 into elongated holes.
  • Figure 2 shows a stretched material of this kind. If the material can be secured in this kind of stretched state for its final application, for example, by sewing the material at its edges into a form that will provide flotation or impact absorption, the openings 2 will remain open and the material will permit the passage of air to ventilate the skin beneath it.
  • the material according to the invention is placed loosely as a sheet-like piece in the desired space, such as a reserved pocket within the trousers of an ice-hockey player, which requires some other way to keep the openings open to ensure ventilation.
  • the openings can be kept open particularly by laminating, to one side of the material, a fabric of a sufficiently open weave that air can pass through it freely, but which, when attached to the entire backing, gives the material a shape in which the openings are open.
  • This kind of lamination also creates another big advantage of the material according to the invention, i.e., flexibility. This is because, if a sheet-like material is used, which has not been processed in any way, the material will be stiff. Now, instead, the material will be made flexible by opening its structure.
  • the raw substance of the material according to the invention can be any mainly plastic-based material at all that is suitable for the purpose and which has the desired characteristics.
  • the closed-cell foamed plastics made for many purposes from polyethene and polyvinyl chloride are also suitable for this invention.
  • the cellular plastic material does not have to be closed-cell.
  • the invention can be adapted in many ways, without deviating from the inventive idea or the scope of the protection defined by the accompanying Claims.
  • the above-described applications lie relatively tightly against a person's skin, as a costume of some kind, this need not be so in every case.
  • the applications may also be such, in which the material according to the invention is used as an external structure, with which a person's skin only comes into contact now and then.
  • Possible examples include seat covers, shoe insoles and similar applications.
  • seat cushions are used with garden furniture in summer, and should preferably be of a material that does not absorb water, because then the seats need not be protected as carefully from showers of rain and similar occurrences. Closed-cell plastic does not absorb water, but in the heat of summer it is a sweaty material to sit on.
  • the solution is to use a material according to the invention in the seat cushions.
  • horse blankets are often made from a felt-based material, The felt becomes wet both from the animal's sweat and from rain, etc, after which it undoubtedly becomes unpleasant and retains heat poorly.
  • a material according to the invention which does not absorb water and is flexible and breathes, can be used to make a much warmer and more comfortable horse blanket.
  • One area of use is as a material with excellent thermal insulation. Such applications include various thermal jackets and so-called survival suits.
