    摘要: The subject of the patent application is a self-closing ventilation insert for ventilating textiles, shoes or articles made up of at least two air-permeable layers, an absorber layer arranged between the air-permeable layers, coverings above the air-permeable layers and at least one protective element. The absorber arranged in the chambers of the ventilation insert swells when it absorbs moisture and thereby closes the chambers of the ventilation insert to make them impermeable to water and air. When the ventilation insert is dried, the chambers open and become permeable to air again. Furthermore, a method of producing the ventilation insert by injection moulding is described. The ventilation insert according to the invention may be used in a wide variety of areas, both in the clothing sector and in technical areas.

    摘要: The present invention relates to a shoe having an improved dual hardness dowel-lift with superior wear and non-slip characteristics. The dual hardness dowel-lift includes a hard polyurethane top piece (19) and a soft polyurethane bottom piece (21). The bottom piece is cast onto the top piece. The bottom piece is a softer material which possesses a hardness lower than the top piece as measured by the Shore A hardness test, and preferably is a thermoset polyurethane elastomer.
