Definitions

  • the invention relates to a carrying device according to the preamble of claim 1.
  • a carrying device of this type designed as a backpack, elongated bodies made of rigid material, e.g. Moldings made of wood, inserted. These bodies caused pressure points on the user while wearing, which caused pain during a long march. The body also increased the weight of the backpack, which was undesirable.
  • the object of the invention is to eliminate the shortcomings of the known designs and to create a carrying device which, on the one hand, is lighter than the previously known and, on the other hand, does not cause pressure points on the back of the user even when worn for a long time.
  • this object is achieved according to the invention by the features of the characterizing part of this claim. Because air chambers are used to stiffen the front wall, the weight of the carrying device is reduced and, moreover, the shape of the carrying device is also well adapted to the body brought about by the user.
  • a safety valve is additionally used to close the nozzle, which prevents the air from escaping when the plug is inadvertently removed from the inlet nozzle.
  • the measure of claim 5 allows a sensitive change in the inflation pressure. However, the use of an air pump or a bellows is necessary.
  • the subject of claim 6 simplifies the manufacture of the carrying device, and the fastening of the two carrying straps is improved, since the fastening seams extend over a large part of the front wall.
  • the measure of claim 7 enables a good support of the front wall of the carrying device on the back of the user.
  • Fig. 1 is a side view of the carrying device in the form of a backpack in the direction of arrow A in Fig. 2, partly. cut along the line I - I in Fig. 2, and Fig. 2 is a view in the direction of arrow B in Fig. 1, wherein in the left half of the stiffening bead is not yet inflated, in the right half, however, is already inflated.
  • the backpack 1 shown in the drawing has a front wall 2 and a rear wall 3. Both walls 2 and 3 are connected to one another by a narrow side wall 4 which extends over the entire circumference of the backpack 1. In the upper area of the narrow side wall 4, a zipper 5 is sewn in, which in the open state enables the backpack 1 to be filled and emptied in a known manner.
  • two stiffening beads 6, 7 are sewn from a material. These stiffening beads 6, 7 sit up in the top ren sections 8.9 of shoulder straps. In the area of its lower ends, two rings 10, 11 are fastened to the backpack 1 and are used in a known manner for hanging a waist belt, not shown. Furthermore, in the region of the lower ends of the stiffening beads 6, 7, the lower sections 12, 13 of the carrying straps are fastened to the front wall 2. These are inserted in buckles which are fastened to the free end of the upper sections 8, 9. A relative movement of the backpack 1 with respect to the body of the user when wearing is prevented by the abdominal belt or a chest belt, also not shown.
  • a tubular body 14 made of air-impermeable material is accommodated inside each stiffening bead 6 or 7, which is provided with an inlet nozzle 15 for inflation.
  • Each inlet spout 15 extends through a hole in the stiffening bead 6 and 7, respectively.
  • the inlet spout 15 is closed by a stopper 16 which is connected to the spout 15 by a band 17 or the like. The plug 16 can therefore not be lost.
  • a safety valve 18 in the form of a flap, which prevents the air from escaping when the plug 16 is inadvertently removed from the inlet spout 15.
  • the air from the tubular body 14 is expediently let out, the stiffening beads 6 and 7 taking on a wide-squeezed shape, as they do is shown in Fig. 2 in the left half.
  • each of the plugs 16 is removed from the associated inlet spout 15 and each tubular body 14 is inflated by mouth.
  • the gtopfen 16 are reinserted into the inlet spouts 15, and the backpack 1 can then be used (see FIG. 2 right half.
  • a check valve can be inserted into each inlet nozzle, the valve body of which is lifted from its seat by hand when the tubular body is emptied. Since the valve body only lifts off the valve seat against the force of a spring when the tubular body is filled, the use of an air pump or a bellows is recommended in this case.
  • the pressure in the tubular body can be adjusted more sensitively by means of a non-return valve, especially since part of the air blown into the body escapes when the tubular body is inflated with the mouth before the stopper has closed the inlet nozzle. This sensitive adjustment of the air pressure is particularly important when large loads have to be carried and the air pressure is to be so great that the front wall is stiffened accordingly, but so small that the wearer has no pressure points on his back.
  • Another modification is to provide the two stiffening beads with zippers extending in their longitudinal direction, which make it easy to replace the tubular bodies.

Abstract

Ce dispositif à porter se porte sur l'épaule avec au moins une bretelle et est adjacent au corps de l'utilisateur par au moins un bourrelet de renforcement. En vue, d'une part, de réduire le poids du dispositif à porter (1) se présentant par exemple sous la forme d'un sac à dos, et d'autre part, d'empêcher même en cas de port prolongé la formation de marques de pression sur le dos de l'utilisateur, chaque bourrelet de renforcement (6 et 7) se présente sous forme de chambre à air gonflable par l'intermédiaire d'un bec d'admission (15) obturable.
