Definitions

  • the innovation relates to a hammock with a mat and a loop-shaped design at the head and foot end for receiving fastening rods.
  • Hammocks for example made of knotted nets, are known and, in addition to the strength requirements for absorbing the weight of a person, must also be weatherproof, since they are mainly used outdoors.
  • the innovation is based on the task of creating a new type of hammock with the greatest possible comfort, easy handling and low weight.
  • a hammock is proposed according to the innovation, in which the mat or the like from a with a textile fabric made of organic and / or inorganic fibers, threads, tapes.
  • Reinforced elastic cross-linked foam sheet with a tensile strength of at least 0.20 N / mm 2 and a tear resistance of at least 1.0 N / mm and an elongation at break of at least 80 to 120% at a bulk density of about 30 to 130, preferably 30 to 80 kg / m 3 is built up.
  • Suitable elastic cross-linked foams are, for example, the closed-cell, chemically cross-linked polyolefin foams, which are water-repellent and have good light stability, and at the same time are still cushioning and insulating.
  • the textile reinforcement can preferably be a coarse reinforcing fabric or knitted fabric, which is either applied on one side or is laminated as an intermediate layer between two foam webs.
  • a non-bulky textile fabric that can be used advantageously consists of a fabric, in particular a ribbon fabric based on plastics such as polyolefins, such as polyethylene tapes.
  • the head and foot ends of the foam sheet are preferably turned over to form loops and the envelope is in particular welded, glued or sewn to the mat.
  • a fastening rod can then be inserted into the loop thus formed, to which the ropes for hanging the hammock are then attached.
  • sew, weld or glue on the head and foot ends of the mat in particular a woven or knitted or laid textile fabric made of plastic to form a loop on the top and / or bottom of the mat.
  • the loop can be attached to the head and foot ends throughout the entire width of the mat, but it is also possible to attach only loop sections in sections.
  • the material for the loops can also consist of a plastic film, for example, a material selection is advantageous which enables a homogeneous connection, for example by welding with the material of the mat.
  • the surface of the foam web forming the mat can be laminated with a film made of plastic, for example a polyolefin film if the foam consists of polyolefins.
  • a film made of plastic for example a polyolefin film if the foam consists of polyolefins.
  • Such a thin film of approximately 30 to 50 ⁇ m can also be colored or printed in a colorful manner, and it is also possible to emboss it in a simple manner in order to improve the surface grip of the mat.
  • the foam sheets of selected raw densities provided in accordance with the innovation are used, which do not allow the weight of the mat to become too large and yet have sufficient strength properties, hammocks with a lying surface of approximately 2 m length to 1 m width can be produced, the mat having a thickness between Can have 5 to 20 mm.
  • the mat can consist of a foam sheet or two foam sheets laminated together. It is also possible to combine two foam sheets with different densities, for example that the foam sheet with the lower density is set softer and forms the top of the mat, while a foam sheet with a higher density and thus stiffer forms the underside of the mat and in combination with the textile reinforcement ensures a sufficient absorption of the loading forces.
  • a particular advantage of the hammock according to the innovation can be seen in the fact that it is very durable and long-lasting due to the rot-resistant materials used and, moreover, it ensures a high level of comfort due to the elastic foam sheets used. If the mat stays outdoors for a long time, it is also conceivable to perforate it in the middle area, to ensure easy water drainage. The hat can also be perforated at intervals for reasons of higher air circulation.
  • Figure 1 the principle of a hammock is shown, which essentially serves to accommodate a person from the mat 1, the mat 1 being connected at its head and foot ends to the rod 2, on which the tether 3 for hanging the mat attack.
  • the rods 2 are preferably inserted through a loop-like design of the head and foot ends of the mat and held therein.
  • the design of the mat 1 is shown schematically.
  • the mat 1 consists, for example, of a foam sheet made of chemically crosslinked polyethylene foam, a thickness of 10 mm and a length of the mat of 1.70 to 2.50 m, preferably about 2 m and a width of about 0.6 to 1.0 m .
  • the foam has, for example, a bulk density of 50 kg / m 3 , a tensile strength measured according to DIN 53571 of 0.4 N / mm 2 , elongation at break measured according to DIN 53571 of 90%, tear propagation resistance measured according to DIN 53577 of 1.9 N / mm , a compressive stress at 25% deformation measured according to DIN 53577 of 70 KN / m 2 , an impact elasticity measured according to DIN 53512 of 45% and a water absorption after 28 days measured according to DIN 53428 less than 3.0% by volume and a water vapor diffusion - Resistance factor f measured according to DIN 53429 of 3000.
  • the top 10 of the foam sheet forming the mat 1, which forms the lying side, can be embossed, for example, or, if necessary, laminated and embossed with a plastic film, for example a 30 to 50 ⁇ m thick polyethylene film.
  • the underside 11 of the foam web forming the mat is reinforced with a fabric 7, not shown, which is laminated in, for example made of polyester threads or polyamide threads or polypropylene threads or a fabric made of polyethylene ribbon fabric.
  • the foam sheet for the mat 1 is folded over at the front ends, ie at the ends forming the head and foot ends, and the folded over edge 12 is glued or welded to the mat in the region 6, for example, or sewn along one or more seams 5.
  • the mat according to the innovation is flexible and can be easily folded up and transported by rolling it up. It is very easy to clean and gives a comfortable feeling of comfort due to the cushioning effect of the foam sheet used.
  • FIG. 3 shows a further possibility of designing the hammock according to the invention.
  • the mat 1 is formed by two foam webs 1a, 1b, between which the textile reinforcement layer 7 is laminated.
  • the two foam sheets 1a, 1b directly to one another and to attach the textile reinforcement layer 7 on the underside, as shown in FIG. 2.
  • the two outer sides of the foam sheets 1a, 1b, namely the top 10 and the bottom 11 are either embossed or laminated with a cover layer, for example a plastic film, which may can be embossed or also provided with a fabric-like cover, for example based on plastic and / or natural fibers.
  • loops 4 are formed, for example, on the end faces of the mat by welding or gluing or sewing, if necessary in addition to an adhesive connection of tapes 8, which can also consist, for example, of a textile woven fabric made of plastic fibers, such as, for example, polyethylene tape fabric .
  • tapes 8 can also consist, for example, of a textile woven fabric made of plastic fibers, such as, for example, polyethylene tape fabric .
  • a riveting of the straps 8 forming the loops to the mat 1 is also conceivable.
  • Polyester fabric or polyamide fabric or fabrics additionally coated with PVC or polyethylene can also be used, for example, as reinforcing textile fabrics.
