Embodiment approach

[0039] Now refer to Figures 1 to 4B A first embodiment of the method according to the invention for producing a shoe with an air pumping device arranged in the heel region is described.

[0040] figure 1 A schematic side view is shown of the three basic components used to manufacture the shoe 1 , namely the upper 2 , the midsole 3 and the outsole 4 .

[0041] The upper 2 includes an upper material portion 21 and a sole portion 22 . In this context, sole portion 22 shall refer to the ground-facing portion of the upper and to which the sole structure described below is attached. The upper material portion 21 is the rest of the upper 2 . Sole portion 22 generally includes an insole and may also include additional layers of the shoe, such as an inset sole. In some embodiments, a separate insole can also be dispensed with, eg the leather of the upper can surround the foot starting from the upper material part, eg in the case of eg moccasins.

[0042] The midsole 3 is preferab...

Abstract

The invention relates to a method for producing a shoe with an air pump device bellows which is arranged in the heel region, wherein an upper (2), a midsole (3), and an outsole (4) are first provided.The lower face (32) of the midsole (3) has a recess (36) for forming a cavity for the bellows and a surface which surrounds the recess on all sides and which comprises a surface profile, and the upper face (41) of the outsole (4) has a surface with a surface profile which complements the surface profile of the lower face of the midsole. The horizontal extension of the upper face (41) of the outsole (4) and of a sole section (22) of the upper (2) is greater than the horizontal extension of the midsole (3) such that the outsole (4) and the upper (2) protrude beyond the centered midsole (3) on all sides. In order to connect the upper (2), the midsole (3), and the outsole (4), the midsole (3) is first adhered onto the sole section (22) in a centered manner, and the upper (2) together with themidsole (3) are pressed onto the outsole (4) which is provided in the base element (6) of an injection mold. In the process, the complementary surfaces are adhered such that the cavity of the recess(36) is completely enclosed. The upper (2), the midsole (3), and the outsole (4) are then enclosed by an injection mold, and the outsole (4) upper face (41) surface regions which are not covered by the midsole (3), the outer surfaces of the midsole (3), and the lower face and adjacent lateral surface regions of the upper (2) are overmolded with an edge sole region plastic.

Description

technical field [0001] The invention relates to a method for producing a shoe comprising an air pumping device arranged in the heel area and having at least one bellows, into which at least one air intake channel opens and into the interior of the shoe At least one air guiding channel is connected to at least one bellows, wherein an upper having an upper material portion and a sole portion with a lower side, a midsole having an upper side and a lower side and an outsole having an upper side are provided, wherein the midsole Recess with at least one cavity for constituting at least one bellows of air pumping means, wherein upper, midsole and outsole are connected to each other by first connecting the underside of the sole part of the upper to the midsole The upper side, and then connect the composite structure consisting of the upper and midsole to the outsole, or first connect the lower side of the midsole to the upper side of the outsole, and then connect the composite struct...
