Definitions

  • the back cushion of the present backpack advantageously has the shape of a three-dimensional structure which consists of a multiplicity of plastic threads which intersect in places and which are connected to one another at the crossing points or at crossing points, preferably welded.
  • the back cushion thus created creates a wide air channel between the back wall of the backpack and formed on the back of the rucksack carrier, through which a very good air circulation is ensured and the body's sweat is largely dissipated.
  • the back cushion thus obtained cannot absorb or store moisture due to the relatively large loop widths and the nature of the plastic threads. It is therefore a permanently ventilated zone in which sweat can evaporate immediately.
  • the knitted fabric of the back cushion consists of a multiplicity of threads which intersect in places and which are connected to one another, in particular welded, at the intersection points or a part thereof.
  • the threads of the knitted fabric are advantageously made from a thermoplastic, that is to say from a plastic which is not self-flowing at room temperature and can be deformed repeatedly at elevated temperature, such as, for example, polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyamides (PA) etc., i.e. from plastics that are built up from uncrosslinked macromolecules.
  • the mat-shaped back cushion is particularly preferably detachably attached to the backpack. It can therefore be detached from the backpack during a break and used as a seat cushion. This is particularly advantageous in damp or cold places, since there is no capillary action which absorbs the moisture and passes it on to the seated wearer.
  • the shoulder straps are usually infinitely adjustable via a correspondingly shaped buckle and are therefore detachably attached to the lower ends of the rucksack or to short straps, the shoulder straps can be separated. Therefore, the hat can easily have an elongated opening in its upper edge region through which shoulder straps of the backpack are passed. Furthermore, for better attachment, the hat can also be provided in its lower region with openings for the passage of lower belts. Mats made in this way are suitable for retrofitting backpacks.
  • a flat edge area can be provided with a fabric which is provided on the side facing the backpack with an adhesive layer which hooks with a corresponding counterpart in the manner of a burdock.
  • a rolling device can press down the edges of the mat and these edges can be melted so that the edges are formed flat.
  • FIG. 1 shows a backpack 1 with two shoulder straps 2 and 3, a waist belt 4, a holder 5, a cushion mat 6 and a body 7, hereinafter also called a container or bag, with an upper part 8.
  • the holder 5 holds the shoulder straps 2 and 3 and is part of a frame to which the bag 7 is attached with its upper part 8.
  • the bracket 5 overlaps with a collar 9 an upper V-shaped flat edge 10 of the cushion mat 6.
  • the cushion mat 6 has a second lower flat edge 11 at its lower end 12, which is between the waist belt 4 and the bag 7 or the frame is releasably clamped.
  • FIG. 2 shows the cushion mat 6, which consists of threads which intersect in places and which are connected or welded to one another at the crossing points or at crossing points.
  • the threads used for mat production are melt-spun from a large number of possible thermoplastic polymers or made from thermosets in another suitable manner. The production of such mats is described for example in DE-PS 25 30 499.
  • the hat 6 is a three-dimensional knitted fabric made of 1-40 mm high, 0.5-30 mm wide, in particular 2-30 mm high, 1-20 mm wide, preferably 5-20 mm high, 3-10 mm wide loops of a thermoplastic Plastic.
  • the weight of this had 6 is 200-900 g / m2, in particular 400-675 g / m2, preferably 500 g / m2.
  • the hat 6 has an upper v-shaped recess 13 through which a lateral displacement of the hat 6 can be prevented.
  • a V-shaped upper flat edge 10 of the hat 6 delimits the recess 13.
  • Fig. 3 shows the holder 5 with the collar 9.
  • the holder 5 has essentially the size of the recess 13 and is shaped so that the collar 9 engages over the flat edge 10 of the mat 6.
  • FIG. 7 and 8 show a method for producing the mat 20, also referred to below as knitted fabric, with a table 40, a rolling device 41, three lasers 42, 43 and 44, two deflectors 45 and 46 and two hot air blowers 47.
  • the knitted fabric 20 is driven by the polygonal rolling device 41 and slides in the direction 48 over the table 40.
  • Two lasers 42 and 43 are arranged in front of the rolling device, which separate irregular edge strips 24a and 25a and straighten the mat 20.
  • Two deflectors 45 and 46 lead the edge strips 24a and 25a for recycling.
  • the edges 24 and 25 remaining in the knitted fabric are pressed down by plates 49 of the rolling device 41 and coated with a hot air stream from the hot air blowers 47.
  • FIG. 10 shows a second roller 61 which has two beads 62 which replace the deflectors 59 and 60.
  • the edges of the back cushion 1' are preferably heated in the manner shown in FIG. 14 with a hot air blower (not shown) and away from the smooth side 2 'by a predetermined angle , which is preferably in a range of 90 ° to 180 °, bent.
  • the resulting back cushion 1 ' has rounded edges without sharp corners or the like.
  • the degree of the bending depends on the respective requirements for the back cushion 1 '.
  • FIG. 14 shows a bend through 180 °, with which a double thickness of the side edges can be achieved. According to FIG. 15, it is also conceivable to achieve an even greater thickness of the side edges will roll the edge areas beyond 180 °. Depending on requirements, it is also conceivable to reinforce only a certain part of the side edges more or less in the manner described. The greater the thickness of a side edge, the greater its rigidity.
  • the one wall 5' of the cover 10 'against which the humps 4' rest has Velcro fastener parts 7 'on the outside can be locked to corresponding Velcro fasteners 12 'which are attached to the back wall 11' of the backpack.
  • two Velcro strips 12 'spaced apart in the transverse direction run vertically on the back wall 11' of the backpack.
  • the side 6 'and the cover parts covering the side edges of the back cushion 1' are made of an air-permeable material, the side 5 'of the cover 10' can also be air-impermeable.
  • FIG. 17 shows an embodiment in which a preferably upwardly open and preferably closable pocket is formed on the back wall of the backpack 11 'by sewing or by another attachment of a power supply 13', into which the cushion layer 1 'can optionally be inserted .
  • a pipe 22, in particular made of plastic, can be introduced into the center of the rolled-up edge area, which is preferably perforated for the purpose of ventilation.
  • the vertically extending tubes 22 can advantageously serve to receive telescopic walking sticks, which can simply be inserted into them from above and thus transported.
  • the edge region is preferably bent through an angle of approximately 270 °.
  • the hip belts 23 can also be formed by the described cushion layer 1 in the area of their rear and lateral bearing surfaces.
  • This cushion layer is preferably covered by a network structure.
  • the back cushion 1 ′′ also has two opposite ones can have smooth or flat surfaces 2 'and 2''which are spaced apart from one another, loop surfaces running in the surfaces 2', 2 '' and between the same plastic threads.
  • the plastic threads are firmly connected to one another at the respective crossing points.
  • this connection takes place in that the viscous and heated plastic threads emerging from the nozzle arrangements lie against one another and cross-link during the loop-like laying on a base at the crossover points.
  • the firm connections at the crossing points ensure that a compression of the back cushion 1 ′′ is opposed because, because of the many connecting points of the plastic threads, a relatively stable structure is created in the space enclosed by the back cushion 1 ′.
  • connections in the flat surfaces ensure that the back cushion 1 'is also very stable with regard to tensile and compressive forces in or parallel to its flat surfaces 2', 2 '' and therefore maintains its shape.
  • the advantages described above also apply if the back cushion 1 'described in connection with FIGS. 11 to 13 is formed with plastic bumps (4') which are firmly connected to one another at the crossing points.
