Definitions

  • the invention relates to a backpack with a back pad and method for manufacturing the back cushion and the use of this back cushion as a seat cushion.
  • Backpacks are straps that are essentially bags use when hiking and there for recording of small items such as handkerchiefs and purses as well as food supplies. Larger backpacks are designed in such a way that they also have utensils for the stay can record outdoors. Such backpacks serve then to accommodate tents and sleeping bags as well as clothing to change. Hence these backpacks very large and often heavy, so that this Strain uncomfortably on the back of the wearer. Because the carrier itself in addition to being physically stressed, he quickly becomes too favorable climatic conditions start to sweat. A particularly critical point is the back area of the carrier on which the backpack rests.
  • DE-GM 86 22 768 is a backpack with a back pad in the form of a coarse-mesh elastic grid made of plastic, leather or the like known that on the outside of the pack sack essentially on the support area Back of the backpack carrier is attached covering.
  • This grille is between the back of the backpack carrier and maintain a space between the stuff sack, the one Ventilation between the stuff sack and the back of the Backpack carrier allows.
  • This ventilation is, however not effective because of the space between the grid and the actual backpack back wall closed to the sides is.
  • Other problems are that this is relative coarse-meshed lattice itself, complicated from bars and built up interwoven plastic fabric tapes is and therefore not easy and inexpensive to manufacture and that the grille is firmly attached to the backpack is, the attachment with strips of cloth relatively expensive is.
  • US-A-4 324 012 discloses a backpack with a back pad out, which is formed as a knitted fabric, the a variety of intersecting and in places Crossing points interconnected plastic threads exist. Because the knitted fabric in a side closed pocket is arranged, there is only the possibility of a limited Ventilation of the space between the back of the backpack carrier and the backpack.
  • the object of the present invention is a To create a backpack with a back pad, which is Back cushion e.g. compared to the backpack after the US-A-4 324 012 very good ventilation of the space between the backpack and the back of the backpack carrier.
  • the back cushion of the present advantageously has Backpack in the form of a three-dimensional structure on that from a variety of intersecting in places Plastic threads exist at the crossing points or connected at intersections, are preferably welded.
  • Back cushion becomes a wide air channel between the Backpack back wall and the back of the backpack carrier formed, which ensures very good air circulation and the body's sweat is largely removed becomes.
  • this can be done Back cushion, which is inexpensive to manufacture, because of the relatively large loop widths and the nature the plastic threads do not absorb moisture or to save. It therefore provides a permanently ventilated Zone in which the sweat can evaporate immediately.
  • the back cushion is advantageously in the form of a hump Mat trained.
  • This is a knitted fabric Plastic threads hump-shaped on one side of the mat Form increases and on the other hand one smooth surface with large mesh size, the cross connections formed by one or more of the threads are.
  • the bumps of the back cushion are particularly advantageous formed in that the taken from a nozzle assembly hot plastic threads on a roller with hump-shaped Surveys are applied or flow from above, the roller reciprocating in the axial direction is moved.
  • the flow rate is the Threads larger than the take-off speed of the roller, so that the thread loops accumulate on the roller surface.
  • the smooth side of the mat so produced is preferred by a counter pressure roller, or a belt, in particular made a teflon tape.
  • the knitted fabric of the back cushion is simple from a large number of intersecting parts and at the intersection or part of it interconnected, especially welded threads.
  • the threads of the knitted fabric are advantageous from one thermoplastic made, that is one that is not self-flowing at room temperature and Repeatable plastic deformable at elevated temperature, such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyamides (PA) etc., so from plastics that are made up of uncrosslinked macromolecules build up.
  • the knitted fabric however also from cross-linked plastics, the is called from thermosets, e.g. made of acrylic glass, polytetrafluoroethylene (PTFE) and the like be.
  • thermosets e.g. made of acrylic glass, polytetrafluoroethylene (PTFE) and the like be.
  • the mat-shaped back cushion is particularly preferred detachably attached to the backpack. It can therefore be during a Break from backpack and used as a seat cushion become. This is particularly true on damp or cold Make advantageous because there is no capillary action is, which absorbs the moisture and this on the seated Carrier passes on.
  • the shoulder straps usually have a corresponding shaped buckle infinitely adjustable and therefore detachable at the lower tip ends of the backpack or on short ones Straps are attached, the shoulder straps can be separated. Therefore, the mat can be easily in have an elongated opening in their upper edge region, carried through the shoulder straps of the backpack are. Furthermore, the mat can be attached better also in its lower area with openings for Pass through lower belts. Executed in this way Mats are suitable for retrofitting backpacks.
  • edges of the mat are flat and therefore hardly resilient and are quasi rigid, they are suitable Devices on the backpack in an advantageous manner clampable. Suitable as devices for clamping grooved strips or plastics with a U-profile on the frame of the backpack. These edges are also more advantageous Way overlapped by a collar device, so that the mat is held on the backpack. This Edges can also be clamped between the frame and waist belt be.
  • a flat edge area can also be provided with a fabric be on the side facing the backpack is provided with an adhesive layer, which with a corresponding Counterpart hooked like a burdock.
  • the edges of the mat openings have, through which a cord is drawn, the Cord can be detachably attached to the backpack. Can too these openings serve as buttonholes.
  • a rolling device can advantageously the edges press down on the mat and these edges can melt so that the edges are formed flat.
  • edges are advantageously made by means of a simple hot air blower melted and deformed.
  • the bent edge areas on the back cushion sliding friction is preferably between the Edge area and the back cushion and / or in front of the humps the cushion layer a damping layer, in particular a foam or foam rubber layer is arranged.
  • the back cushion in a cover is particularly preferred arranged, which consists of an air-permeable material, taking one side of this envelope with the help of Velcro fasteners on the back of the backpack detachable is attachable.
  • knitted fabric Protection is also sought for the knitted fabric as an upholstered mat for backpacks per se.
  • This knitted fabric can be in advantageously provided as a retrofit part for backpacks be.
  • back baskets with a rigid container like a basket or tub on a rack e.g. e.g. Scabies used in the harvest such a knitted fabric can be used.
