Definitions

  • the invention relates to a sole for shoes, consisting of at least one essentially rigid rear part and of a flexible front part connected to this rear part approximately in the ball area, at least one of the two parts consisting of plastic.
  • the term "sole” is used to refer to shoe soles with or without an outsole that also form the footbed, but also insoles, insoles and insoles that are only loosely inserted into a shoe.
  • rigid soles have the advantage that they support the foot in an orthopedic manner.
  • Wood is primarily used as the material for rigid soles, here also plywood or pressed wood, but cork, leather fiber materials and plastics can also be used, provided they have the required strength.
  • the object of the present invention is to avoid this disadvantage and to create a sole in which a permanent connection between the essentially rigid rear part and the flexible front part is ensured.
  • the invention is based on a sole of the type described in the introduction and essentially consists in the fact that one of the two parts, preferably the rear part, consists of a material having a cell structure, the cells of this part mostly being partially open at the connecting surface, and that the other of the two parts, preferably the flexible front part, is formed from a plastic connected to the first-mentioned part by foaming.
  • one of the two parts has a cell structure with cells that are at least partially open on the connecting surface with the other part ensures that when this other part is foamed during the foaming process, the not yet cured foam material penetrates into the open cells on the connecting surface and solidifies there in such a way that a mechanical connection is established between the two parts, which can withstand even the heaviest loads.
  • the part having the cell structure can consist of a polymer having a cell structure, of wood, optionally of wood arranged in layers, of cork, optionally of cork arranged in layers and / or of combinations of these materials arranged in layers. If this part having the cell structure is formed from polymers and if the foamed part also consists of such polymers, a chemical connection takes place in addition to the mechanical connection between the two parts by the chemical reaction between the polymers.
  • the front part can protrude over the rear part on its underside and can be provided with an extension which at least partially extends along the rear part and is foamed on the underside thereof and which is integrally formed with the front part.
  • the connection between the front part and the rear part takes place not only along the connecting surface where the front part and the rear part touch each other, but also via the projection which is formed in one piece with the front part and which is foamed on the underside of the rear part, so that the strength this connection is thereby further enlarged.
  • such an embodiment has the advantage that, according to a further feature of the invention, the protruding area of the front part and the attachment foamed on the rear part can form the outsole, so that the fastening of a separate outsole is not necessary.
  • the essentially rigid rear part can be provided with fillers, in particular if it consists of a polymer.
  • these fillers can be wooden parts, cork parts and / or leather parts, in particular leather fiber materials, that is, substances that also have a cell structure.
  • the use of such fillers not only saves on polymeric material, but these fillers also stiffen and reinforce the essentially rigid rear part and it is possible to achieve a special appearance of the surface of this rear part with these fillers.
  • the fillers from very small bubbles, the thin shell of which consists of elastic vinylidene chloride copolymer and / or vinyl chloride copolymer and whose hollow core contains a gas, preferably air.
  • a gas preferably air.
  • the essentially rigid rear part consists of rigid polyurethane foamed in a mold.
  • a predominantly open-cell structure is created, i.e. the cells formed are connected to one another so that the material forming the flexible front part can penetrate deeply into the cells of the essentially rigid rear part and therefore a very firm mechanical connection is achieved.
  • the essentially rigid rear part made of foamable and optionally filled with homopolymers, copolymers and copolymers with a hardness of more than 60 Shore D, such as e.g. Polyvinyl chloride or polystyrene exist.
  • Such materials have a predominantly closed-cell structure, i.e. the cells formed are largely not connected to one another, but due to the large number of cells, a good mechanical connection to the flexible front part can also be produced here.
  • the flexible front part consists of foamed polymers with a hardness of 26 to 98 Shore A, preferably from 45 to 78 Shore A, and with a density of 0.3 to 0.95, preferably from 0.45 to 0 , 78.
  • polymers can be used for both the substantially rigid rear part and for the flexible front part, in addition to the mechanical connection which is brought about by the material penetrating into the open cells of one part when the other part is foamed achieve a chemical bond by chemical reaction between the polymers.
  • the top of at least the front part can be provided with a cover, for example made of plywood, cork or leather.
  • this connecting surface of the front part has an indentation according to a further feature of the invention and is preferably concave. This not only increases the connection area compared to a plane connection surface, but also ensures a smooth transition between the essentially rigid rear part and the flexible front part, in particular if, according to a further feature of the invention, the edge areas of the connection surface of the front part are tangential merge into the top and / or bottom of the rear part. At the top of the sole in particular, such a stepless transition is very important for a comfortable fit.
  • a further improvement in the connection between the essentially rigid rear part and the flexible front part can be achieved by projecting at least one projection in the central region of the connecting surface of the front part, which protrudes into a correspondingly shaped recess in the rear part.
  • Such an embodiment, in which an even firmer connection is achieved, is particularly advantageous in the case of soles which are subject to high stress and which simultaneously form the insole and / or the footbed.
  • the recess expands expediently towards the inside of the rear part and is, for example, dovetail-shaped.
  • At least one anchoring body, fastening part or the like which runs transversely to the longitudinal direction of the sole and serves to connect the front part to the upper part of the shoe. arranged, which extends at least to the lateral boundary of the front part.
  • an anchoring body, fastening part or the like can consist, for example, of a metallic spring pin, but can also be formed from another material, for example from plastic or from wood.
  • anchoring body, fastening part or the like is, on the one hand, well anchored in the flexible front part and, on the other hand, a firm connection of the shoe upper part to the anchoring body, fastening part or the like is made possible, so that a secure connection the upper of the shoe is also guaranteed with the front of the shoe sole.
  • a separate anchoring body, fastening part or the like can be arranged in the region of each of the two lateral boundaries of the front part, which extends only over a certain region into the interior of the front part.
  • an anchoring body, fastening part or the like extending over the entire width of the front part is provided, so that the upper part can be fastened to the two ends of the same anchoring body, fastening part or the like.
  • a lateral pulling out of the anchoring body, fastening part or the like from the front part is prevented with certainty.
  • this anchoring body, fastening part or the like can be provided according to the invention with its ends extending to the lateral limitation of the front part with openings which receive pins, nails, clamps penetrating the upper part of the shoe , Bolts or the like.
  • Bolts or the like are determined.
  • screw bolts possibly those with a self-tapping thread, can be screwed into these openings, thereby ensuring a secure connection of the upper part to the anchoring body, fastening part or the like.
  • the anchoring body, fastening part or the like is provided with projections which protrude from the lateral boundaries of the front part and which penetrate the upper part.
  • projections which protrude from the lateral boundaries of the front part and which penetrate the upper part.
  • FIG. 1 shows a sole designed according to the invention in a section in the longitudinal direction of the sole for a women's shoe and FIG. 2 for a clog.
  • the soles shown in the drawing consist of a substantially rigid rear part 1 and a flexible front part 2 connected to it.
  • the substantially rigid rear part 1 is made of a polymer having a cell structure, e.g. made of foamed hard polyurethane or foamed polyvinyl chloride or polystyrene.
  • the flexible front part 2 is preferably made of polyurethane, which is foamed onto the essentially rigid rear part 1. Fillers can be embedded in the essentially rigid rear part 1, namely either wooden parts, cork parts and / or leather parts, in particular leather fiber materials, which reinforce the essentially rigid rear part 1 and give the surface of this rear part a special appearance.
  • tiny bubbles can be embedded in the essentially rigid rear part 1, the thin shell of which consists of elastic finylidene cholide copolymer and / or vinyl chloride copolymer and whose hollow core contains a gas, preferably air. These bubbles also form a cell structure in the rear part 1, which is required for a good mechanical connection of the rear part to the foamed flexible front part 2.
  • connection surface of the front part 2 is concave and merges tangentially into both the upper side 4 and the lower side 5 of the rear part 1.
  • the essentially rigid rear part 1 is made of wood, to which the flexible front part 2, which is made of polyurethane, for example, is foamed.
  • the front part 2 protrudes on its underside over the rear part 1 and is formed in one piece with an extension 2 ′ which extends along the rear part 1 and is foamed on the underside 5 of the rear part 1. This not only improves the connection between the front part 2 and rear part 1, but also the outsole is formed at the same time.
  • the connecting surface of the front part 2 is concave again and merges tangentially into the upper side 4 and the lower side 5 of the essentially rigid rear part 1.
  • a protrusion 6 protrudes in the central region of the connecting surface 3 and engages in a dovetail-shaped recess 7 in the rear part 1, as a result of which the connection between the front part and the rear part is further improved.
  • the flexible front part 2 made of foamed polyurethane has a cover 8 made of plywood, cork or leather in order to improve the wearing comfort. If this cover consists of leather, it can extend to the essentially rigid rear part 1, since the leather can follow the bending processes in the ball area at the junction between the essentially rigid rear part 1 and the flexible front part 2.
  • cover 8 does not extend to the essentially rigid rear part 1, so that the bending process in the bale area is not hindered. In such a case, an elastic intermediate piece can be inserted between the essentially rigid rear part and the cover.
  • anchoring bodies, fastening parts or the like 9 are also provided in the flexible front part 2, which extend to the lateral boundary of the front part 2.
  • These anchoring bodies, fastening parts or the like. 9, which serve to firmly connect the upper part of the shoe in the area of the front part 2 to the sole, can be formed, for example, by tension pins which consist of a longitudinally slit metallic tube in which the upper part pins, nails, clamps, screws, especially those with self-tapping threads, etc. that can penetrate the shoe.
  • the anchoring body, fastening elements or the like 9 can be formed from a wooden pin in which nails can be driven in or screws can be screwed in, or from a plastic cylinder provided with openings, wherein pins, bolts or the like can also be inserted into the openings are.
  • the anchoring bodies, fastening elements or the like. 9 can be provided with projections which project beyond the lateral boundaries of the front part 2 and penetrate the upper part of the shoe and are then deformed to form a rivet head.
  • the approaches can also be provided with a screw thread onto which a screw nut is screwed.
  • the essentially rigid rear part 1 is first preformed and the preformed part is inserted into a mold. If this essentially rigid rear part 1 is made of wood or cork, pretreatment of the connecting surface is generally not necessary, since these materials have open cells anyway. If, on the other hand, the essentially rigid rear part 1 consists of a polymer having a cell structure, that is to say, for example, of polyvinyl chloride or polystyrene, the cells must be opened on the connecting surface 3 and, if appropriate, also on the underside 5. For this purpose, these surfaces are either roughened mechanically or chemically pretreated with a solvent.
  • a suitable solvent is, for example, when using foamed polyurethane-dimethylformamide and when using foamed polystyrene-toluene.
  • At least the surface facing the sole of the foot, preferably also the side surfaces of the sole, is processed, for example by grinding or milling.
