Embodiment approach

[0038] 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.

[0039] 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 .

[0040] 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.

[0041] The midsole 3 is preferab...

Abstract

Method for producing a shoe with an air-pumping device configured with a bellows in the midsole, the shoe comprising an air-pumping device with a bellows arranged in the heel area, providing an upper, having a recess on the underside and surrounding the recess on each side with The contoured surface midsole and upper side have an outsole with a surface contoured surface complementary to the surface contour of the underside of the midsole. The upper side of the outsole and the sole portion of the upper have a greater horizontal extent than the midsole so that the outsole and upper extend beyond the central midsole. To connect the upper, midsole and outsole, the midsole is bonded centrally to the sole part and the upper and midsole are bonded to the outsole provided in the base element of the injection mould. The complementary surfaces are then bonded to close the cavity of the recess. The injection mold encloses the upper, midsole and outsole, and the upper surface area of ​​the outsole not covered by the midsole, the outer surface of the midsole, and the lower side and adjacent side surface areas of the upper are made of plastic for the sole edge area plastic wrap.

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...
