Definitions

  • the innovation relates to a self-inflating cushion, especially a lying mat, with a foam sheet made of open-celled flexible polyurethane foam, which is glued on both sides and at the edge with airtight cover sheets, and with an air valve on one side edge.
  • Such cushions which are mostly used in the form of lying mats, have a size of about 190x60 cm and a thickness of 20-50 mm, for example. Since they can be rolled up very closely when not in use, they are particularly suitable for hikers and mountaineers due to their small transport volume.
  • the valve which is usually attached to the side, is simply opened, which causes the foam to roll out and the air to be sucked into the mat due to the expansion efforts of the enclosed foam, so that it automatically smoothes and assumes a shape and volume as it des expanded foam corresponds.
  • the valve is closed - if necessary after further blowing in air. This means that the air can no longer escape and the upholstery or hat can be used and, in particular, offers good thermal insulation and padding against the floor on which they are laid out.
  • the innovation is based on the task of designing a cushion and, in particular, a lying mat of the type described at the outset in such a way that a reduction in weight is possible at least while maintaining the existing comfort, so that the handling is thereby further improved.
  • the invention provides that the foam sheet has at least partially penetrating openings, which are covered by continuous cover sheets.
  • the weight of the cushion or mat can be significantly reduced without the performance properties in any way suffering.
  • These openings can penetrate the foam sheet vertically.
  • the openings are expediently arranged in rows which are offset from one another and have a diameter of 10-50 mm and a mutual edge distance of 10-120 mm.
  • openings can run transversely to the longitudinal extent or in the direction of the longitudinal extent of the cushion or also at an angle to the longitudinal extent.
  • the openings extend in the longitudinal and transverse directions of the cushion and thereby cross over.
  • openings expediently run approximately in the middle height of the thickness of the cushion.
  • foam sheet is divided in the middle into two layers lying one above the other, the at least one contact surface of which has a continuous perforation profile.
  • each of the two contact surfaces lying on top of one another can also have a profiling.
  • This profiling is expediently approximately wavy with waves extending over the entire length and / or width of the contact surfaces.
  • the profiling of the upper and lower layers can run parallel to one another such that the wave crests of both profiles lie on top of each other.
  • the profiles of the upper and lower layers run at an angle to one another and form intersecting openings.
  • the profiles of the upper and lower layers can each have different shapes and / or sizes.
  • top and bottom layers may consist of a material of different hardness.
  • such a mat has an internal rectangular foam sheet 1 made of open-cell, highly elastic flexible polyurethane foam, which is glued on the top and bottom with airtight rubberized cover sheets 2 and 3.
  • the laterally projecting edge 4 of these cover sheets 2 and 3 is also glued airtight together.
  • a valve 5 penetrating the two cover sheets 2 and 3 is inserted in order to fill the lying mat with air or to push the air out of the mat.
  • the foam sheet 1 is now provided at regular intervals with the foam layer 1 fully penetrating punched 6 and 7, which are covered on the top and bottom, however, by the two cover sheets 2 and 3.
  • FIG. 1 and 2 are shown in A partial mat punched out 6 and 7 of different diameters and different distances is shown in order to show the possible variations more clearly.
  • These punchings 6 and 7 expediently have a diameter of about 10-50mm and can be arranged at intervals of 10-120mm from each other.
  • the punched holes 6 and 7 are arranged in several rows next to each other, the punched holes of one row being offset by half the distance from the punched holes of the other row. This results in a very even distribution of the punched holes 6 and 7 over the entire area.
  • these punchings 6 and 7 can reduce the weight of the lying mat by up to 20 percent in total.
  • the cover sheet regions 9 of the cover sheets 2 and 3 bulge outwards above and below the openings 6 and 7, respectively, since they do not come from below are held by foam.
  • These bulges 9 bring two additional advantages, namely, on the one hand, the slip resistance of the mat is increased and, on the other hand, the nub profile practically achieved thereby has a massaging effect on the body of the person lying on it.
  • the lying mat can also be rolled up thinner after use, since it is no longer necessary to compress as much foam material.
  • the foam sheet is shown fully penetrating punchings. However, it is also possible that these punched-out sections do not penetrate the foam sheet fully, but only over a certain height, so that the bulges 9 shown then form only on one side.
  • FIG. 3 A further possibility of reducing the material of such a foam sheet is shown in FIG. 3, according to which the foam sheet 10 is provided with horizontal openings in the form of continuous channels 11 or. These openings can extend in the form of the channels 11 shown in dashed lines transversely to the longitudinal extent of the foam sheet or, as shown by the channels 12, in the longitudinal direction of the foam sheet 10.
  • channels 11 and 12 are provided in both directions and crossing each other, a further reduction in material and thus weight is possible.
  • these channels 11 and 12 are provided approximately at the middle height of the foam sheet 10. Their diameter should not be more than about a third of the foam sheet.
  • a course at an angle to the longitudinal extent is also possible either only in one direction or in intersecting directions.
  • the foam sheet 20 is divided in the middle and thus consists of the two layers 21 and 22 lying on top of one another, each having approximately the same thickness.
  • the contact surfaces of the two foam surfaces 21 and 22 are provided with a profile 23 and 24 according to the illustrated embodiment.
  • these profiles 23 and 24 are wave-shaped, approximately corresponding to a sine line, the profiles 23 and 24 being at right angles to one another, so that each intersecting wave crests and wave troughs result.
  • the proposed profiling results in a material saving of approximately 25%, ie the mat is approximately the same thickness as an unprofiled mat 25% lighter.
  • the profiling width i.e. the distance between two wave crests from each other must not be less than 5 mm.
  • Decisive for size and type of profiling is essentially the desired comfort of this mat, i.e. the profiles must not be so large that there is a drop in comfort or the mat is pushed through.
  • any other wave-shaped or wedge-shaped design is also conceivable.
  • the profiles can be at any angle to each other, i.e. For example, they can also be arranged at an angle to each other up to the extreme case of a parallel course. If the profiling of the two layers 21 and 22 runs in the same direction, it should then also have the same size and configuration, so that the wave crests of the upper and lower layers lie one on top of the other.
  • top layer 21 and bottom layer 22 can also each be made of a material of different properties, i.e. in particular, differ in hardness, so that - depending on which layer is on top - there is softer or harder cushioning behavior.
