Definitions

  • the invention relates to a shoe sole with a sole front part which merges into a sole rear part via a sole middle part, wherein the sole of the sole facing, preferably orthopedically shaped, sole upper side is at least partially formed by the upper side of an upper sole part made of wood or wood-like materials, the underside of which is at least in Area of the sole front part and in the area of the sole rear part is connected to the upper side of a lower sole part made of elastic material.
  • the middle part of the sole has the joint support on the upper side of the sole, the rear part of the sole contains the heel.
  • Soles which consist of an upper sole part made of wood and a lower sole part made of an elastic material and fastened to the underside thereof.
  • this lower sole part which forms the outsole, is arranged only in the area of the sole front part and in the area of the heel and consists of a part made of rubber or polyvinyl chloride which is thin in relation to the upper sole part.
  • soles which consist of two parts made of wood and which are connected to one another by a flexible intermediate part made of foamed polyurethane, it is also already known to also form the lower sole part which forms the outsole from polyurethane and integrally with the intermediate part from the parts Foam wood.
  • the sole rear part also consists practically entirely of wood, only the underside of the heel is covered with a thin tread made of elastic material.
  • Soles with an upper sole part made of wood have the advantage that they have a temperature and moisture regulating effect and support the foot in an orthopedically correct manner, especially when this is known per se, the upper side of the sole has an orthopedic shape, for example with an inner joint support, an outer joint support, a toe barrier and the like. is provided.
  • Soles are also already known which consist entirely of an elastic plastic material which has a shock-absorbing and shock-absorbing effect.
  • these soles do not have any hygienic properties because, for example, they do not have a moisture-regulating effect, but rather promote the production of foot sweat, and also do not guarantee orthopedically correct support for the foot.
  • the present invention has for its object to provide a shoe sole that has good hygienic properties and ensures optimal support of the foot while protecting the entire joint apparatus.
  • the invention is based on a shoe sole of the type described at the outset and essentially consists in the fact that the thickness of the lower sole part, measured perpendicularly to the upper side of the sole, in the area of the rear sole part is at least one and a half times, preferably at least twice the thickness of the lower sole part in the area of the sole front part and that the lower part of the sole has outsole properties at least in the area of the rear sole part and - as is known per se - is molded or foamed onto the upper sole part.
  • a shoe sole designed in this way has an optimal shock-absorbing and shock-absorbing effect in the area of the heel, where this is particularly important, and ensures a soft appearance. Because the lower sole part has outsole properties at least in the area of the heel, it is not necessary to attach a separate outsole or a separate heel mark.
  • the shoe sole according to the invention is also to a large extent sound-absorbing, and annoying rattling noises, such as occur when walking with known wooden soles, are thus practically completely avoided in the shoe sole according to the invention.
  • the thickness of the lower sole part - measured perpendicular to the upper side of the sole - in the area of the sole rear part is at least one third of the thickness of the upper sole part in the area of the sole rear part, preferably at least as large as the thickness of the upper sole part in the area of the sole rear part . It is expedient if the thickness of the lower sole part - measured perpendicular to the upper side of the sole - in the area of the sole rear part is greater than the thickness of the upper sole part in the area of the sole rear part or a multiple of this thickness.
  • both the lower sole part arranged in the region of the sole front part and the lower sole part arranged in the region of the sole rear part are molded or foamed onto the upper sole part.
  • the arrangement is expediently such that the rear sole part predominantly consists of one piece with the lower sole part trained and molded together with this lower sole part on the upper sole part or foamed heel.
  • This heel can be made entirely of the material forming the lower sole part.
  • the material of the lower sole part since the underside of this heel forms the tread of the sole, the material of the lower sole part must have running properties. But the paragraph must also have the necessary stability.
  • a core made of a different material than the material of the heel can be arranged in the heel according to a further feature of the invention.
  • This core can consist of a material whose elasticity is less than that of the material of the heel and thus also of the lower part of the sole, for example of wood.
  • the core can be formed in one piece with the upper part of the sole.
  • Such a core of hardness Rem material is advantageous, for example, if the material of the lower sole part is too soft and therefore, if the entire heel consisted of this material, the heel would not be sufficiently stable.
  • the core consists of a material whose density is less than that of the material of the heel.
  • the lower sole part can be divided into two, one part being arranged in the area of the sole front part and the other part in the area of the sole rear part. However, it is useful if the lower sole part consists of a single piece, which extends over the entire underside of the upper sole part.
  • the inventive design of the shoe sole should not only achieve an optimal shock-absorbing, shock-absorbing and sound-absorbing effect in the area of the heel, but in the area of the entire sole. This is achieved in that, according to a further feature of the invention, the thickness of the lower sole part, measured perpendicular to the upper side of the sole, is greater in the front part of the sole, preferably in the area of the ball of the foot, than in the area of the middle part of the sole.
  • a flexible, shock-absorbing support of the foot is achieved in the front part of the sole, especially in the ball area.
  • Such a flexible shock-absorbing support is particularly important in the heel area and in the ball area, since these are the areas where the foot appears when walking.
  • An expedient embodiment of the shoe sole according to the invention is given when the thickness of the lower sole part, measured perpendicular to the upper side of the sole, increases in a wedge shape at least in the area of the sole rear part against the rear end of the shoe sole. This not only has an optimal shock-absorbing and shock-absorbing effect, but also achieved an elegant appearance of the shoe sole according to the invention.
  • the thickness of the lower sole part is at least more than a third, preferably at least more than half, of the total sole thickness in the front part of the sole, preferably in the ball area thereof.
  • the upper sole part of the shoe sole according to the invention can consist of solid wood. Such an upper sole part can be produced in a simple manner by milling, it not being necessary to give the underside a specific shape, since the lower sole part is molded or foamed on the underside. Furthermore, the upper part of the sole can consist of wood veneer or of small wood particles which are connected to one another by a binder. In this embodiment, which is usually referred to as pressed wood or homogeneous wood, a corresponding shaping of this upper part can be achieved in a simple manner.
  • the upper part of the sole consists of plywood with at least three, preferably five to seven, layers of wood.
  • Such a plywood part can easily be brought into a desired, for example orthopedic, shape by pressing, the fact that the pressing process can be found with relatively few layers, the pressing process is simplified, the pressing pressure and the dwell time in the press being reduced can.
  • the upper part of the sole can be made of cork, both natural cork and pressed cork consisting of small cork particles connected by a binder, for example latex, can be used.
  • Such an upper sole part can be provided on its underside with a base which is not made of wood or wood-like materials.
  • the underside of the upper sole part can have a continuous course, that is to say it does not have any discontinuities such as corners, edges or the like, which means that they are produced is simplified. Since the lower sole part is molded or foamed on this underside in any case, this underside need not have any special shape.
  • the underside of the upper sole part preferably runs continuously upwards towards the rear end of the shoe sole, which also results in an optimal shaping of the lower sole part which is molded or foamed onto this underside of the upper sole part.
  • the lower sole part molded or foamed onto the upper sole part expediently consists, at least in the area of the sole rear part, of an elastic plastic material, preferably with a cell structure, whereby the desired elastic, shock-absorbing and shock-absorbing properties are optimally guaranteed.
  • an elastic plastic material preferably with a cell structure
  • these properties are further improved.
  • the lower sole part molded or foamed onto the upper sole part at least in the area of the rear sole part, consists of polyurethane.
  • polyurethane When foaming, polyurethane combines in an excellent way with the upper sole part made of wood or wood-like materials, whereby on the one hand a mechanical connection is achieved in that the polyurethane penetrates into the pores of the wood during the foaming process and thereby firmly anchors it to the wood is achieved, on the other hand, a chemical connection comes about in that the isocyanate groups of the polyurethane-forming material react chemically with the OH groups of the wood during the foaming process.
  • the cell structure can be achieved, for example, by using a foamed plastic, but also in that, according to the invention, hollow microspheres are contained in the plastic material, the thin shell of which consists of vinylidene chloride copolymer and the core of which is a gas holds.
  • the hollow microspheres mentioned can also be embedded in a foamed plastic to increase the number of cells.
  • the plastic material can, for example, be formed from foamed, from a polyester-based polyol component with 0.1 to 0.5% water content and optionally from up to a maximum of 5% propellant additive, for example halogenated hydrocarbon or another volatile compound, and from an isocyanate-containing polyurethane, the The ratio of polyol component: isocyanate is between 100: 65 and 100: 155. According to the invention, the density of such a plastic material is then between 0.35 and 0.6, in particular between 0.43 and 0.53, preferably 0.48.
  • the plastic material can also be formed from foamed, from a polyol component based on polyether, with 0.01 to 0.5% water content and from a maximum of 10% propellant additive, for example halogenated hydrocarbon or another volatile compound, and from an isocyanate-containing polyurethane, where the ratio of polyol component: isocyanate is between 100:40 and 100:70.

  • the plastic material can consist of a polybutadiene crosslinked with isocyanate, for example by admixing the hollow microspheres with a cell structure.
  • a material has the particular advantage that it is hydrolysis-resistant and not water-absorbent.
  • the plastic material can consist of a polyol component based on polyester and / or polyether, of polybutadiene, of isocyanate and optionally of water and a blowing agent, that is to say of a mixture of polyurethane based on polyester or polyether and polybutadiene.
  • the lower sole part in the unprocessed state i.e. before grinding or milling, has a hardness of 40 to 60 Shore A, preferably 45 to 55 Shore A, and in the processed state, i.e. after grinding or milling Hardness from 20 to 40 Shore A, preferably from 25 to 35 Shore A.
  • the lower part of the sole can be pulled up at least at the sole tip and / or at the heel edge in the area of the heel up to the upper side of the sole.
  • Such training forms a protection of the upper sole part made of wood in the area of the sole tip and / or the heel by the raised lower sole part made of elastic material.
  • a shock-absorbing effect also occurs when an obstacle is struck with the tip of the sole or with the heel.
  • such an embodiment results in a reduced need for wood, since no wood is required in those places where the lower sole part is raised.
  • the human skin is protected, particularly in the area of the heel, where, when the upper side of the sole is designed as an inwardly arched heel bed, the upper edge of the side surface of the sole can sometimes produce a callus causes.
  • the arrangement can be made in such a way that the upper sole part is delimited in the area of the sole tip and the heel edge by a straight line, which is followed by the raised part.
  • this raised part is arched in a top view of the upper side of the sole and merges into the side surface of the upper sole part or the edge of the sole.
  • the lower sole part can be pulled up at least partially beyond the upper side of the sole. This results in an increased lateral boundary surface of the sole at the raised locations, which is advantageous for permanent fastening of the shoe upper, especially by gluing.
  • the raised part is expediently arranged in recesses on the side surface of the upper sole part, so that the outer surface of this raised part is flush with the sole side surface and does not protrude.
  • an intermediate part made of an isocyanate-crosslinked, plasticized polybutadiene which is attached to the upper sole part, preferably by gluing, can be arranged in the ball area between the underside of the upper sole part and the molded or foamed lower sole part. is attached.
  • This intermediate part preferably contains hollow microspheres, the thin shell of which consists of vinylidene chloride copolymer and which contain a gas on the inside.
  • the upper sole part can consist of at least two parts which are connected to one another by intermediate parts, which are preferably formed in one piece with the heel and the lower sole part.
  • This design enables the upper sole part made of rigid wood to be bent in the area of the intermediate parts, thereby the sole can adapt to the walking movements.
