  • the hand grip is located on the connecting web, which connects the two pockets to one another.
  • the horizontal division into the two pockets in conjunction with the carrying handle arrangement according to the invention, allows simple use as a double carrying bag, which, with the carrying volume remaining the same as in the backpack shape, has a substantially increased stability, since the center of gravity height is roughly halved compared to the backpack shape.
  • the connecting elements which can be provided in addition to the connecting web enable the two pockets to be quickly connected into a backpack shape in their position when they are unfolded around the connecting web.
  • Carrying in the form of a rucksack is also possible by hanging a rucksack carrying strap over the shoulder, so that this results in the use as a shoulder bag.
  • the connecting section is perpendicular between the arm and the body of the user, and the two pockets hang laterally in front of and behind his body. This way of carrying is very comfortable, especially because of the favorable distribution of the center of gravity towards the middle of the body and the pleasant freedom of movement in the area between the arm and the body.

  • a horizontal and a vertical central axis h and v are drawn in FIG. These axes define the symmetry with respect to which the guide grooves 26 are inclined.
  • the free displacement of the coupling toggles 27 in the guide grooves 26 allows the backpack to be rotated by 180 in its backpack position, whereby e.g. the previously lower pocket is accessible from above. If you now want to carry the backpack on your back in this rotated position, this can be done immediately since the riser anchorages 25 move automatically in their guide grooves and thus automatically adapt to the carrying position. The weight of the backpack alone makes such an adjustment.
  • pocket reinforcement in the form of a plate 29 is provided.
  • this plate 29 has a rotationally symmetrical rotary bearing 28, on which a further plate 30 is rotatably mounted.
  • This double-plate stiffening serves, in the case of a square design of plates and pockets, for variable accessibility of the pockets on all side or zipper sections.
  • the rotary bearing 28 can also be designed to snap into 90 ° segments. This allows the preferred access position to be fixed.
