Description

backpack

The innovation concerns a backpack, consisting of at least one pack sack with a top that can be closed hose-like cover, which is closed at the bottom by a bottom part, shell and bottom part from one durable fabric, the cover on their The upper edge has a finishing seam and the shell and the bottom part are connected to one another at the bottom by a bottom seam are.

The hard-wearing fabric used for this consists of either a coarse twill or drill fabric or a fine fabric made of synthetic fibers. These fabrics have the disadvantage that they are more or less are permeable to water. In order to reduce the water permeability, it is known to use such fabrics impregnate, for example by using silicone-based impregnating agents. This leads to the ingress of water into the pack sack can be reduced, but not prevented. It is therefore with the known rucksacks, the contents of the pack sack that is to be protected from moisture, wrapped in a plastic film.

The task is to design the backpack in such a way that
that it is waterproof.

This task is solved by the characteristic
Features of claim 1. Advantageous embodiments and the sub-claims withdrawable.

Since the outer shell and the outer bottom part from one
consist of hard-wearing fabric, results in a
Known durability backpack. The sack arranged inside the pack sack consists of an art-to-ff coated fabric, which is waterproof for
Leg selection is decisive. The coating side
of the sack faces the cover and the bottom part, which ensures that the coating is not chafed through and also largely not damaged by objects transported in the pack sack
can. If the waterproof bag is damaged anyway, this damage is for example
using a sweat tape on easy
Way repairable. Such a welding adhesive tape is preferably welded onto the coating side, which is made possible if the end seam is cut if the damage occurs to the hose part of the bag Sack not only over the top seam but also over the bottom seam with the
actual packsack is connected.

Embodiments are described below with reference to
Drawings explained in more detail. Show it:
