Definitions

  • the invention relates to a backpack that has a storage space enclosed by walls and two shoulder straps.
  • Backpacks are used in a variety of training courses whenever items of personal use have to be transported over long distances on foot. There is often a desire to listen to music during such walks.
  • Conventional backpacks are, however, poorly suited for the transportation of the entertainment electronics devices required for this purpose. When the devices are transported in the interior of the backpack, the music emitted by them is strongly dampened and is not audible in satisfactory quality. If the device is installed outside the backpack, it is exposed to heat and dust, which is damaging, and on the other hand, the music is usually emitted against the direction of movement of the hiker and is therefore difficult to perceive.
  • the object of the present invention is therefore to improve a backpack of the type mentioned in the introduction in such a way that a radiation of acoustic signals of sufficient quality is ensured even during intended use.
  • At least one loudspeaker is arranged in the region of the walls delimiting the backpack.
  • the arrangement of the loudspeaker in the area of the backpack makes it possible to operate the entertainment electronic device shielded from external influences in the interior of the backpack.
  • the acoustic signals are emitted using the loudspeakers installed in the area of the backpack wall. No additional containers are required for the hiker to carry. Rather, he also keeps his hands free for any purpose when the entertainment electronic device is in operation.
  • a loudspeaker is arranged in the area of one of the side walls of the backpack.
  • this arrangement ensures that the acoustic signals are emitted in a direction which is favorable for their perceptibility, and on the other hand, this arrangement of the loudspeakers makes it possible to play stereophonic music.
  • the wall of the backpack is at least partially heat-insulating.
  • This heat-insulating training enables the operation of electronic entertainment devices even under unfavorable weather conditions. Even in the event of strong solar radiation, the temperature level in the interior of the container is maintained for a long time to ensure that the devices operate smoothly.
  • a backpack essentially consists of walls (1) which enclose a storage space (2).
  • the walls (1) are formed from a front wall (3), a rear wall (4), a roof (5), a floor (6) and side walls (7, 8).
  • a flap (9) is arranged in the area of the rear wall (4) and is detachably connected to the rear wall (4) by a reversible closure (10).
  • the reversible closure (10) is designed as a zipper (11).
  • Loudspeakers (12, 13) are arranged in the area of the side walls (7, 8) and are connected to a headphone switch (16) via cables (14, 15).
  • the headphone switch (16) has a headphone jack (17) that enables the connection of headphones.
  • a connecting cable (18) also opens into the headphone switch (16) and has a connector plug (20) in the area of its end facing away from the headphone switch (16), which enables it to be connected to an entertainment electronic device (19).
  • the entertainment electronic device (19) can be arranged in the storage space (2). However, it is also possible to arrange the entertainment electronic device (19) in the interior (21) of an additional pocket (22) which is provided in the region of the rear wall (4).
  • the additional pocket (22) has a zipper (23) which closes it releasably.
  • An additional pocket (24) can also be arranged in the area of the additional pocket (22), which is also detachably closed by a zipper (25).
  • the shoulder belt (27, 28) has shoulder padding (29) in the area of its upper extent in the vertical direction. In the unpadded area of its expansion, the shoulder strap (27, 28) has an adjustment (30) that adjusts its width.
  • the backpack is essentially made of waterproof nylon. But it is also possible to use other weatherproof and tearproof materials.
  • the backpack can be made of heat-insulating materials at least in some areas. It is possible to provide back upholstery (31) in the area of the front wall (3) boundary facing away from the storage space (2).
  • the entertainment electronic device (19) When the backpack is used, the essential part of the goods to be transported is stowed in the storage space (2).
  • the entertainment electronic device (19) is arranged in the area of the additional pocket (22) and is connected to the headphone switch (16) via the connecting cable (18).
  • the signals emitted by the entertainment electronic device (19) can be converted into acoustic signals via headphones or via the loudspeakers (12, 13).
  • the energy supply to the loudspeakers (12, 13) is switched off with the aid of the headphone switch (16) and the acoustic signals are generated only in the area of the headphones.
  • an optimal operating temperature for the entertainment electronic device (19) can be guaranteed over a long operating period.
  • the backpack can also be easily gripped manually and, for example, easily stowed in the area of a luggage rack when stowed in a bus or a railway compartment.
  • the shoulder padding (29) and the back padding (31) allow the backpack to be carried comfortably even during long hikes.
