Definitions

  • the invention relates to a shoe sole with an upper sole part made of wood, the upper, preferably orthopedically shaped, of which forms the support for the sole of the foot, and an outsole made of elastic and flexible material arranged below the upper sole part, the upper sole part being divided into several at least in the ball area is divided transversely to the longitudinal direction of the sole strip, which are connected to each other by flexible intermediate pieces, preferably made of polyurethane foamed onto the wood.
  • the invention further relates to a method for producing such a shoe sole.
  • Shoe soles with an upper sole part made of wood and with an outer sole of elastic and flexible material attached to the underside of this upper sole part have been known for a long time.
  • Such shoe soles have the advantage that they have excellent hygienic properties because they are sweat-wicking and moisture-regulating, and that they support the foot in an orthopedically correct manner, especially when the upper surface of the upper sole part is orthopedically shaped.
  • the rigidity of the shoe soles, whose upper sole part consists entirely of wood is disadvantageous. Bending in the ball area, as is necessary for walking comfortably, is therefore not possible with such shoe soles.
  • the strips located between the flexible intermediate pieces must be narrow, as seen in the longitudinal direction of the sole, in order to be able to accommodate all the elastic intermediate pieces in the ball area.
  • the longitudinal direction of the wood of the wood usually runs in the longitudinal direction of the sole, and the upper part of the sole is divided into strips transversely to it.
  • the strips are loaded unevenly, the strips will break along the longitudinal direction of the wood of the wood, thus transverse to the longitudinal direction of the strips.
  • Such an uneven load occurs, for example, when uneven surfaces are walked on with the sole. Stones that you step on with the sole of your shoe can cause one or more stripes to break.
  • the object of the present invention is to avoid this disadvantage and to form a shoe sole in which the risk of breakage of the narrow strips is avoided.
  • the achievement of the object is, starting from a shoe sole of the type described above, that the strips are formed from at least two parts, the adjacent end faces of which extend essentially in the longitudinal direction of the sole and are likewise connected to one another by flexible intermediate pieces. This creates a shoe sole in which the strips can be bent transversely to the longitudinal direction, that is to say generally in the longitudinal direction of the fiber of the upper sole part made of wood, so that the risk of breakage of these strips when the load is uneven is also eliminated.
  • the method according to the invention for the production of the shoe sole described essentially consists in that several incisions, for example by milling, are made in the ball area on the underside of a piece of wood forming the upper sole part, by means of which this piece of wood forming the upper sole part is at least partially severed so that thereon this piece of wood is inserted into a mold that a liquid plastic material is then introduced into the mold and allowed to solidify, the intermediate pieces and the outsole formed therewith being formed in one piece in the region of the incisions, and that the sole part thus produced is finally removed from the mold.
  • the piece of wood forming the upper sole part does not have to have the exact shape of the upper sole part, but can also be larger, in particular a greater thickness, measured perpendicular to the upper side of the sole, exhibit. In this case, it is in fact possible not to completely cut through the piece of wood forming the upper sole part, but a connection can still be maintained on the upper side thereof, which considerably simplifies insertion into the mold.
  • At least the upper side of the wooden piece forming the upper sole part is processed in a material-lifting manner, preferably by milling or grinding, whereby not only the orthopedic shape of this upper side can be achieved, but also that area is removed in which is still a connection of the wooden piece forming the upper sole part, and thereby the intermediate pieces extend to the top of the upper sole part.
  • FIG. 1 shows a plan view of the shoe sole according to the invention and FIG. 2 shows a section in the longitudinal direction of the sole.
  • the shoe sole according to the invention has an upper sole part 1 made of wood, the orthopedically shaped upper side 2 of which forms the support for the sole of the foot.
  • the upper sole part 1 is divided into a plurality of strips 3 running transversely to the longitudinal direction of the sole, which strips are connected to one another and to the adjacent sections 4, 5 by flexible intermediate pieces 6.
  • the flexible intermediate pieces 6 are preferably made of polyurethane, which is foamed onto the wooden parts 3, 4, 5, which creates a permanent connection between the wooden parts and the flexible intermediate pieces 6.
  • an outsole 7 made of elastic and flexible material, which is formed in one piece with the intermediate pieces 6 and preferably also consists of polyurethane foamed onto the wood.
  • the strips 3 Since the bendability of the sole must be given in the ball area, the strips 3 must be arranged at least in the ball area.
  • the strips 3 are therefore, as can also be seen from the drawing, narrow in the longitudinal direction of the sole. Since with wooden soles the longitudinal fiber usually also runs in the longitudinal direction of the sole, there is a risk of the strips breaking along a longitudinal fiber if the sole is subjected to uneven loading, such as occurs, for example, when walking on an uneven surface. To avoid this risk of breakage of the strips 3 eliminate, the strips 3 consist of at least two parts 3 ', 3'', the subdivision extending essentially in the longitudinal direction of the sole.
  • the mutually adjacent end faces 10 of the individual parts 3 ′, 3 ′′ are likewise connected to one another by flexible intermediate pieces 11, which cause the strips to bend transversely to their longitudinal direction, so that the strips 3 are prevented from breaking.
  • the flexible intermediate pieces 11 can be arranged only in the area of the strips 3, but can also extend beyond the strips, for example up to the sole tip, as is indicated by the broken line in FIG. 1. In this case, the production of the shoe sole is simplified.
  • All intermediate pieces 6, 11 are preferably formed in one piece, so that good cohesion is ensured and production is simplified.
