Shoe having a single-piece sole contruction and active air ventilation

Abstract

A shoe, and production methods for such a shoe, having a single-piece sole construction, in which efficient air circulation in the shoe and thereby directly on the foot of the user of the shoe is made possible with every step of the walking movement of the user.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS[0001]This present application is a national phase application under 35. U.S.C. § 371 of International Application No. PCT / EP2016 / 057079, filed Mar. 31, 2016, and claims the benefit of priority to European Patent Application No. 15 163 208.0 filed on Apr. 10, 2015, the entire contents of each of which are hereby incorporated by reference.FIELD OF THE INVENTION[0002]The present invention relates to a shoe having a single-piece sole construction, in which efficient air circulation in the shoe and thereby directly on the foot of the user of the shoe is made possible with every step of the walking movement of the user and, in particular, to a production method for such a shoe.BACKGROUND OF THE INVENTION[0003]A shoe consists of two main parts, namely the upper part, called the upper, and the lower part, the sole. The upper can comprise an inner upper (lining), intermediate upper (intermediate lining), and outer upper (upper leather). An upper conne...

AI Technical Summary

Benefits of technology

The invention is a shoe with an air pump device that simplifies the production process, reduces costs, and improves ventilation and walking comfort. The air pump device can be a cavity within the shoe or a separate lung that can be set into the cavity. The lung increases air circulation and reduces impact on the sole construction during walking. The air pump device is connected to the sole construction and can regulate air pressure to prevent impact and ensure constant damping. The sole construction can be made of different materials, and an elevated region on the outer surface can reinforce the pumping effect and increase running comfort. The invention allows for healthier and more comfortable running.

Problems solved by technology

However, it has been shown that efficient supply of fresh air is not possible in this way.

The disadvantage of this type of shoe consists in the lack of efficiency of the air circulation in the shoe, due to inefficient drawing in of air by means of the air pump device, in other words due to lack of a pumping effect.

However, it has been shown that the pump mechanism works so inefficiently, simply due to the stress on the air pump device caused in the shoe by the heel of a user during the walking movement, that no significant ventilation of the shoe interior is possible.

However, the ventilation device with the movable pump device is very complicated, in terms of design, and is very susceptible to failure from a mechanical aspect.

However, the production of this sole construction, in which the air pump device is integrated into an upper and lower sole part, is relatively complicated and complex.
