Definitions

  • the invention relates to a method by which for a Orthopedic shoe upper required individual cut pieces can be produced.
  • the shoe uppers are composed of several individual shaft parts.
  • the number and shape of the individual parts depends on the respective shoe model and also depending on whether the shoe held together by eyelets, elastic or Velcro and should be held on the respective foot.
  • eyelets elastic or Velcro and should be held on the respective foot.
  • shoe uppers can cut the same individual parts in large quantities be used. It is different with orthopedic products Shoes. These shoes are individual for each foot customized. The shoes are unique in their form. The Item cuts must therefore be made for each individual shoe be newly manufactured.
  • GB 2 135 170 A describes a method for the standardization of Last, soles and heels known. With this procedure the effort to manufacture shoes is to be standardized the lasts, soles and heels are simplified, so that these parts are better matched. Orthopedic shoes have an individual shape, so that Standardization of lasts or shoe parts not possible are.
  • the ball point marks the widest part of the Forefoot and also determines the slip area for one Shoe.
  • the end of the shaft marks the rear height of the shaft in low shoe models.
  • the break point poses the actual rear end point of the low shoe model
  • the middle of the heel finally shows the highest Point in the heel area.
  • the shoe size is another point of reference.
  • the size of the shoe influences the proportion, for example the shaft parts, such as. B. the eyelet parts in the area of Back of the foot. Additional reference points can also arise depending on whether the orthopedic shoe is for you Hollow foot or flat foot is intended, or whether a wide Areas of normal foot. Because of these markers and other reference points then become the cutting characteristics entered in the groin copy. It is in the Last copy the necessary for sewing the individual parts together Lasting allowance and the other from orthopedic Added allowances required. These offers can be due to padding, the z. B. shortened Feet or missing foot areas may be required.
  • the cutting characteristics are intended for a specific model always look approximately the same, regardless of the respective orthopedic shoe shape.
  • the construction that of the individual cuts is very time consuming.
  • the invention is based on this prior art based on the task of an economically favorable process for the manufacture of an orthopedic shoe upper specify the required individual cuts.
  • the shaft-dependent cutting characteristics are shown by between different marking and / or reference points mathematical functions created and in an electronic Data processing system (EDP) saved. At different shoe models are then correspondingly many Functional cutting characteristics recorded in the EDP, saved and available according to model type.
  • EDP electronic Data processing system
  • the math Functions also depend on the position of the marking and other reference points.
  • the individual cuts can be output in terms of data.
  • the blanks can be graphically displayed on a screen and above also shown or output in the form of drawings become. Graphic representations can show the course of the Visualize construction steps carried out by the computer.
  • the cuts can not only be represented graphically but also also with the help of a cutting plotter made of a flat material such as B. a paper material can be cut out. Cuts can then be placed directly on upper leather skins and cut out the individual parts of a shoe upper become.
  • the new bar copy in particular is advantageous available by entering personal data in the EDP saved. In this way it is possible to have several Models or another one at a later date To produce the shoe upper in a simple manner in that the individual cuts without any further design effort immediately retrieved from the EDP and, for example, by a Cutting plotters can be cut out of a paper web can.
  • the individual lining parts to be used in the shoe upper determine mathematically, if necessary graphically on a screen shown and from a cutter from a Cut out flat material such as paper material become.
  • the lining parts are based on the circumference and in numbers on the upper material blanks and like the upper material blanks described above processed and called up in the same way by computer become.
  • the bar copy 10 shown in dash-dotted lines in FIG. 1 represents the outline of a surface, that in the longitudinal direction seen half modeled lasts of a foot corresponds. This last copy 10 is made by hand. In The last copy 10 shows five marking points: Viewpoint 12, ball point 14, shaft end point 16, Break point 18 and heel center 20. These points are as above already mentioned and represent known construction points in a last copy 10.
  • This bar copy 10 is in an electronic data processing system (EDP) read.
  • EDP electronic data processing system
  • the strip copy 10 i.e. the film
  • a digitizing tablet placed and scanned circumferentially.
  • the above five points are entered into the EDP.
  • the outline and thus the last copy 10 is then digitized Form available in the EDP.
  • the shape of the last copy 10 is then checked and possibly replaced by a new last copy 22.
  • the latter occurs in cases where the inguinal copy 10 is not the corresponds to the exact surface of the last.
  • correction of the inguinal copy 10 and Making a new last copy 22 is on the last the actual distance between the heel center 20 and the lower front edge 24 determined.
  • This distance E1 is on the extension of the viewpoint 12 and Ball point 14 straight lines 25 starting from heel point 20 measured removed. One arrives at one if necessary new edge 26.
  • Viewpoint 12 is also corrected accordingly. It will the distance between the center of the heel 20 and the point of view 12 - directly on the last, along the surface or the outside of the last removed and this distance E2 removed on straight line 25. The viewpoint 12 moves then, if necessary, to the new viewpoint 28.
  • the ball point 14 is now shifted on the straight line 25 so that the distance between viewpoint 12 and ball point 14 the Distance between the new viewpoint 28 and the new bale point 30 corresponds.
  • the distance between the point of view and Bale point represents the so-called leaf length 32
  • Leaf length is clearly visible on a shoe from diagonally above and should therefore with the appropriate orthopedic Shoe must also be available in the correct length and position.
  • the rear area of the inguinal copy 10 is with the new one Last copy 22 congruent, since there with material-related Distortion of the last copy made of foil material is not to be expected.
  • the new last copy 22 is shown in solid lines in FIG. 2.
  • the above five marker points, namely Viewpoint 28, ball point 30, shaft end point 16, Abort point 18 and heel center 20 are entered is the edge 26 and the existing below the heel center 20 Footpoint 40 can be seen. Also the lower construction point 36 is shown.
  • the lower area 34 of the bar copy 22 is now one Stripe area 42 enlarged.
  • This area 42 results from a lasting allowance and possibly from, for example Cork midsole to be made later. In the present In this case, no cork midsole is required and therefore also no corresponding offer is provided.
  • the pince-nez is for sewing together the later cut-out shaft material such as leather material.
  • the Curve 44 is the outline delimiting area 42 below adapted to the curve of the lower region 34 and equalizes the curve curvature 46 there by a less curve curvature 48.
  • curve 44 ends at one point 50. This point lies once on the down extending, tangential extension of the heel curve 52 at foot point 40. The distance from point 40 corresponds to Lasting allowance at this point.
  • From the derby point 58 is entered into the EDP by one Distance value of point 60 determined. Owing to The known construction auxiliary lines then become the model-dependent ones upper construction point 62 (front shaft end) EDP-like in the upper curve area 64 of the last copy 22 determined. Then the upper computer can then Derby sheet 70 calculated and in the last copy 22 can be entered graphically.
