Definitions

  • the invention relates to a sole for shoes, consisting of at least two essentially rigid parts, which at least partially consist of wood or wooden materials and which are flexibly connected to one another in the ball area, wherein in the gap extending across the entire sole width between the opposite end faces of adjacent, essentially rigid parts, an intermediate piece made of flexible material and an outsole made of flexible material are provided on the underside of the essentially rigid parts.
  • the outsole does not necessarily have to run continuously along the entire underside of the essentially rigid parts.
  • Wooden soles are already known. These soles have numerous advantages because they support the foot in an orthopedically favorable manner and are cold-insulating, temperature-regulating and moisture-absorbent, so that wooden soles are hygienic and comfortable to wear. In the case of soles made entirely of wood, however, their rigidity is disadvantageous, since it hinders the rolling movement of the foot when walking.
  • Soles have therefore already been proposed which consist of two wooden parts which are connected to one another in the ball area by a flexible connecting part. This makes the sole flexible and elastic in the ball area and can adapt to the rolling movement of the foot when walking.
  • the flexible connecting part from polyurethane directly foamed onto the wooden parts, as a result of which a secure and firm connection between the wooden parts and the flexible intermediate part is achieved in a simple manner.
  • soles which consist of two parts made of wood, which are connected to each other in the ball area by a flexible intermediate part made of rubber, it is also known to provide the underside in the area of the sole front part with a thin rubber outsole covering.
  • soles which consist of a plurality of layers connected to one another, for example a plurality of layers of wood connected to one another by gluing.
  • the object of the present invention is to achieve a sole on the one hand so that it has all the advantages of a wooden sole, and furthermore it has the desired flexibility in the ball area, but an excellent elastic support of the foot is ensured and annoying rattling noises, such as it does otherwise occur with wooden soles, even if they are provided with a thin outsole on their underside, can be avoided with certainty.
  • the invention solves this problem in that the essentially rigid parts constructed in a manner known per se from layers which run essentially parallel to the tread and / or to the surface facing the sole of the foot form an insole in which at least that immediately adjacent to the sole of the foot Layer of wood or wood-based materials, and on the underside of which an outsole is attached, which is made of a foamed plastic, preferably polyurethane, the thickness of the outsole - measured perpendicular to the tread - in the ball area being greater than the thickness of the essentially rigid parts .
  • Characterized in that the immediately adjacent layer of wood or wood materials, such as cork, is ensured that the sole of the foot rests on the wood, whereby the advantages of the wooden soles described above also occur in the sole according to the invention.
  • the flexibility in the bale area is guaranteed by the intermediate piece made of flexible material.
  • the essentially rigid parts only form the insole in the sole according to the invention, to the underside of which an outsole is attached, which is thicker than the insole at least in the ball area and which consists of a foamed plastic, that is to say of a resilient, elastic material, so that despite the orthopedic support of the individual parts of the foot by the essentially rigid parts, there is a soft, resilient support of the foot in its entirety over the outsole.
  • the outsole can also only extend over the area of the front part of the sole, in which case it is also arranged in the ball area.
  • the essentially rigid parts can consist of plywood.
  • the layers can at least partially consist of pressed wood or at least partially consist of cork.
  • Press cork can also be used.
  • Cork is also a wood-based material, since it is made from tree bark, so it has the advantages of wood, although it also ensures a certain elasticity perpendicular to the tread.
  • the advantages of cork are also given, however, as with pressed wood, practically complete utilization of the existing raw material is made possible, so that no waste is generated.
  • the layers according to the invention can at least partially consist of leather or leather fiber materials, but also of plastic, for example of hard polyurethane or polyvinyl chloride.
  • plastic for example of hard polyurethane or polyvinyl chloride.
  • Foamed plastic This is because it has a cell structure, the cells of which can be at least partially opened at the connecting surfaces by mechanical or chemical treatment, so that the non-hardened material of the connecting part or the outsole or the non-hardened adhesive penetrate into these cells during molding can and solidifies there, so that a very good mechanical connection between the essentially rigid parts and the flexible connecting parts and the outsole is made, which can withstand even heavy loads.
  • the materials forming the individual layers can also be combined with one another. If plastics are used, it is advantageous to provide natural and / or synthetic fillers in the plastic, as a result of which the properties of the plastic can be improved in relation to the wearing comfort of the user of the shoes and the sole is given an elegant appearance.
  • the smallest bubbles can also be provided as fillers, the thin shell of which consists of elastic vinylidene chloride copolymer and the hollow core of which contains a gas, preferably air.
  • the use of such fillers gives the plastic a cell structure, so that the advantages mentioned above also occur when the essentially rigid parts are connected to the flexible connecting part and the outsole.
  • the gap can be filled with a flexible filler, which suitably consists of foamed plastic, preferably polyurethane.
  • outsole and / or the intermediate piece can be foamed or glued to the essentially rigid parts.
  • the drawing shows an embodiment of the shoe sole according to the invention.
  • the shoe sole has an insole, which is formed from two essentially rigid parts 1, 2, on the underside 5 of which an outsole 3 is attached.
  • the gap between the essentially rigid parts 1, 2 is filled by an intermediate piece 4 made of flexible material.
  • the upper side 6 of the essentially rigid parts 1, 2 facing the sole of the foot can have an orthopedic shape.
  • the essentially rigid parts 1, 2 consist of individual layers 7 which run approximately parallel to the bottom 5 or top 6.
  • the layers can all consist of the same material, but it is also possible to form the individual layers 7 from different materials.
  • the top layer consists of wood or wood-based materials, such as cork, since wood has the excellent hygienic properties mentioned at the beginning.
  • the outsole 3 is, at least in the ball area, much thicker than the insole formed by the essentially rigid parts 1, 2. This ensures good elastic support for the foot as a whole.
  • the arrangement can also be such that the width of the gap - measured in the longitudinal direction of the sole - in the edge area adjacent to the sole of the foot, i.e. in the area of the upper side 6, and / or in the edge area adjacent to the tread, i.e. in the area of the underside 5, is larger than the smallest width in the middle region in between.
  • Such a design has the advantage that even with a strong bend in the sole in the ball area, the connecting part 4 does not tear and does not become detached from the essentially rigid parts 1, 2, since in the edge areas, where when the sole is bent, the expansion or compression of the intermediate piece is greatest, more material is available for absorbing the stresses that occur, and as a result the specific elongation or compression is less.
  • this design also increases the connecting area between the intermediate piece 4 and the essentially rigid parts 1, 2.
  • the two edge areas of the gap merge rounded into the central area, so that sharp edges are avoided, in which large tensile and compressive stresses occur during bending, which could lead to destruction of the intermediate piece 4.
  • the edge regions of the gap expediently merge tangentially into the upper side 6, as a result of which there are no steps at the transition point which are perceived as disturbing.
  • the gap is formed symmetrically with respect to a central axis 8 which runs essentially perpendicular to the tread 5 and preferably also to an axis 9 which is perpendicular to this central axis 8 and runs essentially in the longitudinal direction of the sole.
  • This symmetrical design is expediently also provided if the width of the gap in the area of the underside 5 and in the area of the top 6 is greater than in the middle area lying in between.
  • the intermediate piece 4 can consist of different flexible materials. It can be formed, for example, by a flexible filler, which is arranged in the gap after the outsole 3 has been fastened. Of course, however, the intermediate piece 4 can be formed from the same foamed plastic material as the outsole 3, that is to say, for example, consist of foamed polyurethane, and if appropriate can also be formed in one piece with the outsole 3.
  • the attachment of the outsole 3 and the intermediate piece 4 to the essentially rigid parts 1, 2 can be carried out both by gluing and by foaming, with the Variants are possible that one part, for example the outsole 3 or the intermediate piece 4, is glued on, the other part, for example the intermediate piece 4 or the outsole 3, is foamed.
  • the outsole 3 not only provides elastic support for the sole of the foot in its entirety, but the outsole 3 also brings about a connection of the two essentially rigid parts 1, 2, so that it is not absolutely necessary that the intermediate piece 4 with the the gap-defining end faces of the essentially rigid parts 1, 2 is firmly connected.
