Definitions

  • the present invention is related to custom shoes, such as orthopedic shoes, and methods for making the same.
  • the individual production of a custom shoe by a craftsman usually takes place by establishing relevant dimensions of the foot for which the shoe is being made, in order to take into account the length of the foot and—at least in terms of quality—the shape of the foot.
  • the desired outer material of the shoe generally leather, is used to form an upper, which substantially forms the side walls with a slip-on opening and the upper side of the shoe.
  • the open underside of the upper is closed with an insole, which is connected to the upper by means of a Strobel seam.
  • the shoe arrangement formed in this way is drawn over a last, a form that is adapted at least in some parameters to the shape of the foot for which the shoe is being made and over which the shoe is shaped.
  • the invention relates to custom shoes, in particular orthopedic shoes, and a method for producing the same.
  • the custom formed shoe includes an upper or shaped upper with a clearance or opening for an insole. Once produced, it is then drawn with a sewn-in insole over a last and is completed to form the shoe by joining the upper to a sole or outsole.
  • the invention is based on the object of simplifying the production of a custom shoe, in particular an orthopedic shoe, and therefore of making it possible to create less expensive shoes.
  • the method as described above is characterized in that an insert of an elastic textile material is provided in the opening and/or at a lower border of the upper adjacent to a sole region.
  • the upper with the elastic material is then drawn over a last, and the elastic insert is fixed in the stretched state in which it has been drawn onto the last by applied, non-elastic material.
  • a shoe which is simple and inexpensive to produce of the type mentioned above is characterized in that an insert of an elastic textile material is arranged in the region of the opening and/or at the lower border of the upper adjacent to the sole region.
  • This insert of elastic material is fixed in a stretched state by an applied, non-elastic material.
  • the present invention is based on the realization that, during formation of a shoe, the processing step that causes a great amount of time to be expended is the drawing of the upper, provided with the insole, onto the last. Before it is drawn onto the last, the upper can only be roughly adapted to the shape of the foot—and any special features it may have. The final adaptation to the shape of the foot takes place on the last.
  • the last is produced by taking an impression from the foot concerned or has last parts that can be adjusted in relation to one another and by which the shape of the foot can be replicated. For this latter type, it is possible for any irregularities, such as deformations of the ball, to be taken into account by suitable attachments.
  • the upper can be used as a standard upper, because the upper or the insole that is inserted into the lower opening and is joined to the upper is provided with an insert of an elastic textile material.
  • the adaptation to the shape of the last therefore does not take place primarily by stretching the material of the upper, which can of course still be additionally performed in individual cases, but by stretching the elastic textile material.
  • the elastic material is fixed in the assumed state, in the state in which it has been drawn onto the last, i.e., generally in a stretched state, by an applied non-elastic material.
  • This fixing with the non-elastic material is preferably and appropriately performed by adhesive bonding, which may be surface-area adhesive bonding.
  • the insert of the elastic material is provided in the region of the insole, it preferably forms a peripheral border strip of the insole.
  • this does not rule out the possibility of the complete insole being formed from an elastic textile material.
  • the upper itself with an insert of a textile elastic material, the insert in this case preferably being formed as a strip-shaped insert in the lower border of the upper and running parallel to the sole.
  • This strip-shaped insert may be provided peripherally around the shoe, or else be only provided in the front region of the upper, depending on the shape and/or abnormality of the foot that is to be taken into account in the individual case.
  • the fixing of the insert of the elastic textile material forming the insole or part thereof may take place by applying the outsole.
  • the sole, or outsole is usually adhesively bonded to a folded-around border of the material of the upper and covers over the seam between the material of the upper and the insole. Layers of leather, cork, non-elastic textiles, etc., may be used for fixing the elastic material.
  • the upper to by provided with interstitial strips, by which the fitting of the upper on the last can be corrected.
  • the interstitial strips are preferably subsequently covered by the non-elastic material.
  • the method according to the invention also allows the formation of a shoe with a waterproof and water-vapor-permeable lining membrane. If this lining membrane is formed as a closed membrane, it must be formed at least with an elastic base, in order that the stretching of the elastic material performed on the last can also be performed by the lining material.
  • the lining membrane without a base and to introduce a waterproof layer into the sole construction. It is possible, for example, for the non-elastic material, which serves for fixing the elastic material, to be formed such that it is waterproof.
  • FIG. 1 a shows a first exemplary embodiment of a shoe in an intermediate stage of its production process with an elastic strip-shaped insert in the front region of the shoe.
  • FIG. 1 b shows the shoe of FIG. 1 a fitted onto a last.
  • FIG. 2 a shows a modified exemplary embodiment in which the strip-shaped insert is formed peripherally around the shoe.
  • FIG. 2 b shows the shoe of FIG. 1 a fitted onto a last.
  • FIG. 3 a shows a plan view of an underside of an upper with an inserted insole, which has a peripheral insert of an elastic textile.
  • FIG. 3 b shows a plan view of the upper of FIG. 3 a fitted onto a last.
  • FIG. 4 shows a vertical section through a front part of the shoe with an elastic insert in the region of an insole.
  • FIG. 5 shows a representation according to FIG. 4 for an embodiment in which an elastic insert is also provided at the lower border of the material of the upper.
  • FIG. 6 shows a vertical section through an embodiment with a waterproof and water-vapor-permeable lining membrane.
  • FIG. 7 shows an alternative embodiment for a waterproof formation of the shoe.
  • FIGS. 1 a and 1 b show in a side view an upper 1 of a shoe, which forms a peripheral sidewall 2 and an upper side 3 of the shoe with a slip-on opening 4 .
  • a separating line 5 Represented at the lower border of the sidewall 2 is a separating line 5 , which separates a visually detached sole region from a sidewall region.
  • the border of the upper 1 is formed underneath the separating line 5 by a strip-shaped insert 6 of a textile elastic material.
  • the strip-shaped insert 6 is bridged on each side by an interstitial strip 7 that is joined to the material of the upper above the separating line 5 .
  • FIG. 1 a shows the upper 1 in an initial state.
  • FIG. 1 b shows the same upper 1 that has been drawn onto a last 8 . It can be seen that, by drawing the upper 1 onto the last 8 , the insert 6 has been stretched out and now has a greater width than in the initial state of FIG. 1 a . In this stretched-out state, the insert 6 is fixed in the stretched state by a strip 9 of a non-elastic material. For example, the strip 9 is adhesively attached onto the insert 6 and on the underside is sewn to the material of the upper 1 . The strip 9 then also covers the interstitial strips 7 .
  • FIG. 1 does not reveal that the upper 1 has on its underside an opening that is closed by a sewn-in insole before the upper 1 is drawn onto the last 8 .
  • the stretching of the insert 6 of an elastic material and the fixing of the insert 6 in its stretched position with the aid of the strip 9 allows the upper 1 to adapt or adjust to the shape of the foot represented by the last 8 .
  • This adaptation is achieved quickly and unproblematically, without special skills and experience being required for stretching the material of the upper 1 outside of the insert 6 .
  • FIGS. 2 a and 2 b show a comparable exemplary embodiment in which the insert 6 ′ is formed peripherally around the entire shoe, so that an adaptation of the upper 1 to the last 8 is possible over the entire periphery of the upper.
  • a number of bridging interstitial strips 7 are provided.
  • a strip 9 ′ is provided for the fixing of the insert 6 ′ in its stretched state. Strip 9 ′ is therefore formed with such a length and width that it can reach around the entire upper 1 .
  • FIGS. 3 a and 3 b show a plan view of an underside of the upper 1 , which, with a border 10 folded around in the sole region, delimits a clearance or opening 11 of the upper 1 which is closed by a sewn-in insert 12 .
  • the insert 12 consists of an elastic textile material and is represented in FIG. 3 a in an initial position.
  • the insert 12 can be stretched for adaptation to the shape of the last, as is represented in FIG. 3 b .
  • the insert 12 is likewise fixed in its stretched state by applying a non-elastic material, the non-elastic material is preferably attached by adhesion or bonding or other suitable attachment process.
  • FIG. 4 shows that the upper 1 is usually formed by an outer material 13 and a lining material 14 , which are usually adhesively bonded to each other.
  • a Strobel seam 15 is used to join the two layers, 13 , 14 to the border 10 , which together with the insert 12 of elastic material forms the insole.
  • the elastic insert 12 is fixed in its stretched state on the last 8 by an adhesively attached layer 16 of non-elastic material.
  • This non-elastic material 16 is likewise adhesively bonded to the border 10 , whereby the sole region is fixed in the state in which it is stretched on the last 8 .
  • the layer 16 is finished off by an outsole 17 .
  • the outsole 17 is applied in the usual way, as is known in the art, by adhesive bonding, sewing or the like.
  • a strip-shaped insert 6 is also arranged at the transition between the outer material 13 and the border 10 in the sole region. Since the insert 6 of the elastic material must be able to stretch on the last 8 , the lining 14 joined to the outer material 13 is not joined to the insert 6 in the region of the latter but loosely reaches over the insert 6 with an end portion 14 ′. In this way, the lining 14 ′ does not hinder the stretching of the elastic material of insert 6 .
  • the insert 6 is fixed in its stretched state by an adhesively attached strip 18 of a non-elastic material. The strip 18 is able to mark the visual separation that is identified in FIGS. 1 a , 1 b and 2 a , 2 b by the depicted separating line 5 .
  • the lining 14 which is joined continuously to the outer material 13 , is constructed with a waterproof, but water-vapor-permeable membrane.
  • the lining 14 is supplemented by a base 19 of an elastic material, which is likewise waterproof.
  • the base 19 makes it possible for the insert 12 to stretch on the last 8 , in that the base 19 also performs corresponding stretching.
  • the insert 12 is formed in such a way that, when the stretched state of the insert 12 is fixed by the layer 16 of non-elastic material, adhesive passes through the insert 12 stretched on the last. This adhesive reaches the likewise stretched base 19 of the lining 14 , and consequently also fixes the stretching state of the base 19 .
  • the lining 14 is waterproof, but water-vapor-permeable.
  • a projecting border strip 14 ′ which overlaps the stretching zone present here on account of an insert 6 .
  • the lining 14 is firmly joined to the stretched insert 6 , the insert 6 having a non-elastic region 20 .
  • This region 20 is formed by a gauze strip through which adhesive 21 , or a plastic liquefied by heat, can pass to the border of the lining 14 , in order, when it fully reacts, to bond the lining 14 to the insert 6 .
  • This bonding takes place only after the stretching of the insert 6 on the last 8 .
  • the bonding may take place for example by use of a hot-melt polyurethane strip 21 , which liquefies under heat, passes through the gauze strip and, when it cools down, crosslinks to form an elastomer.
  • the strip 18 of non-elastic material can be adhesively attached to fix the stretching state of the insert 6 .
  • the lining 14 may be formed such that it is elastically stretchable.
  • the fixing layer 16 is formed from a waterproof material.
