Description

The present invention relates to a set and a satchel. A satchel is also known as a knapsack. School bags usually have a relatively stiff or rigid outer contour, while school backpacks have a relatively soft and flexible or flexible outer contour. In general, the invention relates to a container that can be carried on the back, in particular a school bag.

US 2009/145711 A1 discloses a set of plate-shaped reinforcing elements with a carrier bag which comprises a bottom, two flexible lateral outer walls, a back wall and a flexible front outer wall, at least one of the lateral outer walls and the front outer wall being an insertion pocket for receiving the reinforcing element for conversion into a more rigid pocket having.

E.g. from the US 2003/057239 A1 the result is to equip a carrying bag, which is equipped with handles for carrying the bag, with a back strap so that it can also be carried on the back, or to design the existing handles for a back strap, depending on the current needs of the user.

JP S49 78302 U discloses a school backpack with a plate-like reinforcing element.

When children come to primary school, they often use a school bag in the form of a satchel at the beginning. Later, they often prefer a school backpack.

The present invention is therefore based on the object of providing a school bag which can be converted from a school bag into a school backpack and vice versa.

According to the invention, this object is achieved by a set according to claim 1. The insertion pocket can also be referred to or designed as a, in particular double-walled, compartment. The reinforcing element is preferably made of, in particular hard / solid, plastic.

In addition, the school backpack normally has a lid flap or a corresponding lid, in particular a flexible or rigid one.

Furthermore, this object is achieved by a school bag according to claim 4.

In particular, it can be provided in the set that the insert pocket has a closable open side. For example, the insert pocket can be closed by means of a Velcro fastener or a zip, in particular an internal zip.

The school backpack advantageously has at least one front pocket accessible from the outside. For example, the front pocket can be a patch pocket.

With regard to the design of the satchel, the same explanations apply as for the school backpack. Normally, the satchel has a lid, in particular a flexible or rigid one, or a corresponding lid flap.

In addition, the pocket of the satchel can have a closable open side.

The front outer wall expediently has an insertion pocket with at least one inserted plate-shaped reinforcing element, which can be removed from the insertion pocket for the purpose of conversion into a school backpack.

Finally, it can be provided that the satchel has at least one front pocket accessible from the outside.

The present invention is based on the surprising finding that the provision of removable reinforcement elements enables the user of the school bag to decide for himself whether he prefers a (reinforced) school bag or a soft school backpack as a school bag.

That in the Figures 1 to 5 shown set 10 of a school backpack 12 and three reinforcing elements 14, 16 and 18 results in a school bag when inserted reinforcing elements 14 to 18. On the other hand, if the reinforcement elements 14 to 18 are omitted or removed, a school backpack results or remains.

The one in the Figures 1 to 5 The school backpack 12 shown comprises a base 20, two basically flexible lateral outer walls 22 and 24, a back wall 26, back straps 28 and 30 attached to the back wall 26 and a basically flexible front outer wall 32. There is one on each of the two lateral outer walls 22 and 24 Side pocket 34 or 36 placed. In addition, each of the lateral outer walls 22 and 24 each has an insertion pocket 38 or 40 for receiving the reinforcing element 14 or 16. The two insertion pockets 38 and 40 are the same size. The same applies to the reinforcing elements 14 and 16. However, the insertion pockets and the reinforcing elements can also be designed differently, but this then does not form part of the present invention.

The reinforcing elements 14 and 16 are plate-shaped. In the present example, they are made of rigid 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 reinforcement element 18 is plate-shaped and made of hard or rigid plastic. The reinforcement elements 14 and 16 are designed for the side walls, while the reinforcement element 18 is specially developed for the front area.

The insertion pocket 44 is located inside the school backpack 12. It is attached to the back of the front outer wall 32 and can be closed, for example, with a Velcro fastener (not shown). It is a double wall Compartment which, according to a particular embodiment of the invention, can be adapted in size 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, they can be opened and closed with a zipper (not shown), which is attached, for example, vertically to the edge of the side and back area. According to a particular embodiment of the invention, these are double-walled compartments which are placed between the outer side pocket 34 or 36 and a large inner compartment.

Also to be mentioned is a cover 46, which covers the interior of the school backpack 12 if necessary.

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

Figure 3 shows the same for the reinforcing element 18.

The Figures 4 and 5 then show by transparent representation the arrangement of the reinforcing elements 14 or 16 and 18 to form a school bag with rigid side and front walls.

A possible procedure for converting a (reinforced) satchel into a (soft) school backpack 12 is described below as an example:
In order to be able to remove the reinforcing elements 14 and 16 on the sides, z. B. a zipper, which is attached to the edge of the side and back area, for example opened from the bottom up. Then the respective reinforcing element 14 or 16 is pulled out to the rear (see, for example. Figures 1 and 2nd ). After the reinforcement elements 14 and 16 have been removed, there is a "crumple effect".

In order to remove the reinforcement element 18 in the front area of the satchel, in this example the lid 46 of the satchel must first be opened. In this example, a Velcro fastener is opened on the inside of the front outer wall 32 and the reinforcing element 18 is then pulled straight up (see, for example, Figure 3 ).

Alternative design options and procedures for inserting / inserting and removing the reinforcing elements are conceivable. These should also be included. This includes, for example, attaching the insertion pockets with the respective openings. It doesn't matter where they are. Closure should also be included, for example with a Velcro fastener, snap fasteners or the like. The material of the reinforcement elements plays no role in the simplest form. Any material that serves as reinforcement for the body and is removable should be included.

The reinforcing elements can be designed, for example, as templates, for example for repainting.

That in the Figure 6 The set 10 shown, comprising a school backpack 12 and three reinforcement elements 14, 16 and 18, differs from the set shown in the previous figures in that the school backpack 12 has no insertion pockets for the reinforcement elements. Instead, the reinforcement elements 14, 16 and 18 can be fastened in the interior of the school backpack 12 by means of, for example, a Velcro fastener connection to the two lateral outer walls 22 and 24 and the front outer wall 32.

For this purpose, the reinforcing elements 14, 16 and 18 each have a Velcro fastener element 48 or 50 or 52 on the side facing outwards, and the corresponding Velcro fastener elements 54 or 56 or 58 on the inside of the school backpack 12. For example, the respective Velcro fastener connection can have a hook and fleece band, mushroom head and velor band, mushroom head and fleece band or mushroom head and mushroom head band. Extruded hooks / mushrooms on knitted fabrics are also conceivable. To make the Velcro fastener elements 48, 50 and 52 easier to see, the respective reinforcing elements 14, 16 and 18 are shown transparently.

The features of the invention disclosed in the present description, in the drawings and in the claims can be essential both individually and in any combination for realizing the invention in its various embodiments, provided that this falls within the scope of the claims.
