Definitions

  • the invention relates to a shoe, in particular sport shoe, having a sole and a shoe upper part connected to the sole.
  • a shoe of the generic type is known from DE 10 2011 108 744 B4.
  • expanded (foamed) thermoplastic polyurethane (E-TPU) is used as the material for the sole of the shoe.
  • WO 2007/082838 A1 also describes that expanded thermoplastic polyurethane (E-TPU) can be advantageously used for shoe soles.
  • DE 203 20 091 U1 shows another shoe of the generic kind; GB 2 016 259 A1 shows a similar solution.
  • Urethane-based thermoplastic elastomer in particular in expanded form, is also described, for example, in WO 2010/010010 A1, to which reference is made in this respect.
  • EP 2 452 969 A1 discloses a process for the production of expandable thermoplastic particles by post-impregnation.
  • EP 2 565 225 A1 describes coated expandable polymer particles.
  • the solution of this object by the invention is characterized in that the sole is made, at least in sections, from an expanded thermoplastic polyolefin (E-TPO), wherein the section of the sole consisting of expanded thermoplastic polyolefin (E-TPO) consists of a plurality of (at first, i.e.
  • E-TPO expanded thermoplastic polyolefin
  • thermoplastic polyolefin forms an insert of the sole
  • further sections of the sole consisting of a material which is not expanded thermoplastic polyolefin
  • the further section of the sole which does not consist of expanded thermoplastic polyolefln, consists at least in sections of an ethylene-vinyl acetate copolymer (EVA), of expanded thermoplastic polyurethane (E-TPU), of thermoplastic polyurethane (TPU), of thermoplastic elastomer (TPE), of polyamide (PA), of foamed polyurethane and/or of rubber material.
  • EVA ethylene-vinyl acetate copolymer
  • EVA expanded thermoplastic polyurethane
  • TPU thermoplastic polyurethane
  • TPE thermoplastic elastomer
  • PA polyamide
  • the aforementioned shape of the plastic body refers to the initial product, i.e. before the plastic bodies are joined together (welded or glued under pressure); the bond causes the individual bodies to deform so that the spherical or ellipsoidal shape is no longer completely retained.
  • the substance-locking bond between the plastic bodies can be achieved by a welding process.
  • the welding process can be carried out in particular by introducing steam into a mould at a pressure of between 1.0 and 4.0 bar, preferably between 1.0 and 2.0 bar. This enables a precise geometric formation of the sole and a simple manufacturing possibility.
  • the substance-locking bond between the plastic bodies can also be achieved by an adhesive process with the addition of an adhesive.
  • the plastic bodies preferably have a weight between 5 mg and 10 mg.
  • the section of the sole consisting of expanded thermoplastic polyolefin has preferably have a density between 100 and 250 g/I (grams per litre).
  • plastic bodies consisting of expanded thermoplastic polyolefin have a density between 70 and 140 g/I before they are joined together.
  • the section consisting of expanded thermoplastic polyolefin can form a midsole of the shoe. An outsole can then be placed under this.
  • the section consisting of expanded thermoplastic polyolefin can, according to a special embodiment of the invention, not extend over the entire height of the sole or midsole.
  • the section consisting of expanded thermoplastic polyolefin is preferably arranged in the heel region of the sole.
  • E-TPO is an expanded thermoplastic elastomer based on olefins, wherein here mainly polypropylene (PP) or ethylene-propylene-diene rubber (EPDM) is used.
  • Thermoplastic polyolefin is therefore a mixture of a polyolefin-based plastic (usually PP) and an elastomer such as EPDM.
  • TPOs are polymer blends that can be produced hard or soft depending on their composition. Hard TPOs, where PP and talc can make up around 75% of the composition, are often used as impact-reinforced plastics. However, soft TPOs have a significantly higher elastomer content, in some cases up to 70%. The advantage over other thermoplastic elastomers is that TPO is on average much cheaper.
  • the invention provides for at least one section of the sole made of E-TPO, i.e. expanded thermoplastic polyolefin (i.e. an elastomer-based olefin).
  • E-TPO expanded thermoplastic polyolefin
  • this material lies roughly between EVA and E-TPU and is therefore used advantageously in the sense of the above task.
  • the proposed material used is up to 30% lighter than E-TPU, which provides respective benefits.
  • the springback property is comparable to that of E-TPU.
  • the pressure is advantageous lower than that required one for processing E-TPU for the same purpose.
  • the manufacturing process is more effective than E-TPU processing.
  • Another advantage is a lower degree of yellowing compared to the E-TPU used up to now.
  • the sole can be connected to the upper part of the shoe (shoe upper) by sewing or gluing, which is known as such.
  • FIG. 1 shows the side view of a sports shoe
  • FIG. 2 shows the section A-B according to FIG. 1 through the sports shoe
  • FIG. 3 shows schematically the detail “X” according to FIG. 2 .
  • FIG. 1 shows a shoe 1 having a sole 2 and a shoe upper part upper 3 .
  • Shoe 1 has a midsole located between shoe upper part 3 and an outer sole 6 which forms the footprint of the shoe on the ground.
  • FIG. 1 shows a section 4 of sole 2 that is designed as an insert that forms a part of the midsole. This section 4 consists of E-TPO.
  • the remaining sole 2 and in particular the midsole between the shoe upper 2 and the outer sole 6 , consists of a section 7 which does not consist of E-TPO.
  • the section 4 made of E-TPO does not extend over the entire height H of sole 2 , but only part of it.
  • the section 4 made of E-TPO is formed from a plurality of plastic bodies 5 which are substance-locked together.
  • individual plastic bodies 5 as advantageously specified above in terms of size and weight or density, are placed in a mould and joined together using steam with a pressure between 1.0 and 2.0 bar, in which the individual plastic bodies 5 melt on their surface and join with other plastic bodies 5 .
  • the result is a compact material that can be used to form the described section or insert 4 .
  • the complete midsole which is arranged between the shoe upper part 3 and the outer sole 6 , consists of E-TPO, which is not shown in the example.
