BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a knapsack or back pack with at lest one reinforcing element which is curved concavely, as seen from the outside, at least region-by-region in the longitudinal direction and/or in the transverse direction. Such element is received in pockets provided in a rear wall of the knapsack, and enables the rear wall to be deformed concavely in the longitudinal direction and/or in the transverse direction. A support net is stretched between a bottom region of the reinforcing element, e.g. by an elastic supporting strip extending transversely in the bottom region of the reinforcing element, and an upper region of the reinforcing element.
Such a back pack is known from EP-B-0 158 154 wherein there are disclosed two individual, essentially vertical reinforcing members which merge at the top and whose undersides are connected by another horizontal reinforcing member. The upper ends of the vertical reinforcing members are connected together by an additional horizontal connecting piece which projects sideways beyond the ends of the vertical reinforcing members. An elastic support, over which a support net extends, is arranged above the upper horizontal connecting piece. In this manner air ventilation in the back region is presumably achieved during use of the back pack. From the point of view of production and assembly, however, such arrangement is very expensive. In addition, the framework comprising vertical and horizontal reinforcing members and connecting pieces must be almost completely accommodated in a rear side pocket.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a knapsack or back pack of the aforementioned type in such a manner that, while maintaining air ventilation in the back region of the back pack user, not only are the production, assembly and disassembly of the means provided in essence to maintain such air ventilation in the back region and intended to lower the manufacturing costs simplified, but also carrying the back pack becomes more comfortable.
This object is achieved in accordance with the invention in that a reinforcing element is designed as a one-piece plate-shaped structural member, which may or may not be provided with perforations and whose upper and bottom ends alone are clamped detachably in the longitudinal and transverse directions, while bending, between upper and lower pockets of a rear wall of the knapsack.
Therefore, only a single element that is easy to fabricate is necessary to reinforce the back. Such element can be totally assembled and disassembled with a support net with few manipulations. It is merely necessary that the upper end of the reinforcing element according to the invention be received in a short pocket that is open toward the bottom, because the plate-shaped design ensures that the rear wall, concavely deformed, is held everywhere at an adequate distance from the support net. Owing to the short upper pocket, not only is it possible to save material but also assembly and disassembly of the reinforcing element is facilitated. Perforations can be provided in the reinforcing element, on the one hand to also save material, but on the other hand to facilitate the necessary bending and clamping of the reinforcing element during assembly. In the case of the reinforcing element according to the invention, an upper horizontal connecting piece that protrudes sideways and results in the pocket quickly rubbing through due to its shape is avoided.
The upper end of the reinforcing element can have preferably slotted perforations or depressions, which are arranged side by side and through which straps or loops provided on the upper end of the support net are led in the longitudinal direction for the purpose of stretching the support net. The loops can be fixed by sliding a cross rod through all of the loops after the loops have been slid through the perforations on the rear side of the reinforcing element. The many perforations or depressions arranged side by side provide that the support net rest
