That in the FIGS. 1 to 5 shown set 10 of a school backpack 12 and three reinforcing elements 14, 16 and 18 results in inserted reinforcing elements 14 to 18 a satchel. If, on the other hand, the reinforcing elements 14 to 18 are omitted or removed, the result is or remains a school backpack.

The in the FIGS. 1 to 5 School backpack 12 shown comprises a bottom 20, two in principle flexible lateral outer walls 22 and 24, a back wall 26, attached to the back wall 26 back straps 28 and 30 and a basically flexible front outer wall 32. On both lateral outer walls 22 and 24 is one each Side pocket 34 or 36 attached. In addition, each of the lateral outer walls 22 and 24 each have an insertion pocket 38 or 40 for receiving the reinforcing element 14 and 16, respectively. The two insertion pockets 38 and 40 are the same size. The same applies to the reinforcing elements 14 and 16. The insertion pockets and the reinforcing elements can also be designed differently.

The reinforcing elements 14 and 16 are designed plate-shaped. In the present example, they are made of solid or rigid plastic.

Furthermore, a front pocket 42 is placed on the front outer wall 32. The front outer wall 32 also has an insertion pocket 44 for receiving the reinforcing element 18. In the present example, the reinforcing element 18 is designed plate-shaped and made of hard or rigid plastic. The reinforcing elements 14 and 16 are designed for the side walls, while the reinforcing element 18 is designed specifically for the front area.

The insertion pocket 44 is located inside the school backpack 12. It is mounted on the back of the front outer wall 32 and can be closed, for example, with a hook-and-loop fastener (not shown). It is a double-walled Compartment, which according to a particular embodiment of the invention of the dimensions of the dimensions can be adapted exactly to the size of the reinforcing element 18.

The insertion pockets 38 and 40 for the reinforcing elements 14 and 16 are placed directly behind the side pockets 34 and 36. For example, it may be opened and closed with a zipper (not shown), for example mounted perpendicularly to the edge of the side and back areas. It is according to a particular embodiment of the invention to double-walled compartments, which are placed between the outer side pocket 34 and 36 and a large inner compartment.

Furthermore, a lid 46 should be mentioned, which covers the interior of the school backpack 12 if necessary.

The FIGS. 1 and 2 show how can be converted by inserting or inserting the reinforcing elements 14 and 16 in the insertion pockets 38 and 40 in a satchel with relatively stiff side walls by means of belonging to the set 10 reinforcing elements 14 and 16 of the school backpack. If necessary, the resulting satchel can be converted back into the school backpack 12 by removing the reinforcing elements.
