Definitions

  • CH-A-179 427 describes a method for producing orthopedic shoes.
  • a support is attached to a last intended for series production, the dimensions of which at least approximately correspond to a support insert for a sick foot.
  • the shoe made over such a raised last is higher than usual and therefore immediately recognizable as an orthopedic shoe. Feet with a deformed outline cannot be treated with such shoes either.
  • a method is known from US-A-17 89 518, with the aid of which the conformity of a shoe manufacturing last with the human foot used as a model is to be checked.
  • parts made of elastic, transparent film material such as celluloid are molded over the last to be tested and used to manufacture a trial shoe with a sole and heel.
  • US-A-1 789 518 comprises claim 1 through features 1,2,3,4,5,6,7 and 8 of claim 1.
  • GB-A-906 436 describes a method for the production of shoes, in which several layers of fabrics, reinforcements and compensating layers impregnated with hardening plastics are applied in succession on a last corresponding to the shape of the foot in such a way that the finished structure is like a shoe looks. Since the wall of this shoe consists of up to three layers of plastic on top of each other, which are neither permeable to air nor moisture, this shoe cannot possibly be worn for a long time. In the absence of relief from sick and painful areas of the foot, such a shoe should not be regarded as an orthopedic shoe.
  • the present invention has for its object to provide a method of the type mentioned, which relieves the orthopedic shoemaker as much as possible from the side work and fashionable design work and enables him to concentrate entirely on the work on the patient, which in particular the precise manufacture of the Lasts and bespoke shoes made easier and faster and which allows the use of standard and assembled parts.
  • the method according to the invention also begins with the production of a plaster cast, in particular with the aid of plaster bandages.
  • a plaster cast With the aid of this plaster cast, however, only the patient's rear foot shape is transferred exactly to the last, either by removing material there or, according to a further development of the invention, by adding hardening plastic materials.
  • the plaster cast is coated with a release agent. This transfer is limited to the rearfoot area, i. H. on the area from the heel to the ball of the foot; the entire foot shape was always transferred in the prior art.
  • the orthopedic shoemaker can make this model true to the image and get all of the shoe parts required for it partially or completely pre-made from stock. He knows from the outset the prices of the necessary shoe parts, which, thanks to their standard prefabrication, are considerably cheaper than for a one-off production. The orthopedic shoemaker can therefore calculate precisely and supply the patients at a competitive price.
  • Standard strips for example hinged or sliding strips, are preferably used as strips, corresponding to the industrial strips. This is based on the knowledge that 80% of foot deformities only occur in the forefoot area and that, despite different foot shapes in the rear foot area, all production parts can be standardized, e.g. B. the insoles, the heels, the soles, the toe and heel caps and the shafts.
  • a plastic film can preferably be drawn over the sole and side surfaces of the last using the deep-drawing technique and then cut so that a type of insole with an integrally molded rear cap remains.
  • a trial shaft is drawn over the last and pinched and glued onto the cut plastic film. After a heel has been attached, this trial shoe can be put on by the patient for a test run and to check the fit. Any corrections can be marked directly on the trial shoe; the trial shoe can also be cut open in order to check the exact position of the tread and any necessary upholstery, rolling aids and the like.
  • the displayed corrections can be transferred directly to the last, so that errors are practically impossible.
  • the patient can use the catalog to select and select his desired model from a large number of complete shoe models. All about it Required shoe parts such as insoles, toe caps, toe caps, bedding parts, etc. can be completely or partially prefabricated by the master orthopedic shoemaker and then assembled according to the catalog using the dimension strips he has created.
  • plastic instead of leather there are only minimal additional costs, which are, however, already outweighed by the possibility of being able to check both the fit and the appearance of the final custom shoe before it is manufactured.
  • trial shoes are already made from cheap leather lining.
  • the fit size of the final leather shaft could not be determined.
  • these trial shoes could in no way allow the appearance of the finished custom-made shoe to be guessed with sufficient accuracy, since they had no similarity in model to the final shoe.
  • the deep-drawn plastic films mentioned above can be used not only on the sole surface, but also on the top of the last. If, in addition to low shoes, boots, trainers or the like were to be produced for a patient, previously separate lasts had to be made. This is eliminated thanks to the plastic film molded onto the top of the last, which can be cut as a forefoot and / or rearfoot cap depending on the application. The appropriate reinforcement is applied to these cones with the help of cork and / or hardening plastic masses.
  • the orthopedic shoemaker can transform the patient lasts with one handle, in order to manufacture light, open summer shoes, sturdy loafers, sneakers or boots, depending on the patient's wishes, and in doing so, according to the current fashion, the shoe with a drawn, narrow Form a point, with a round point, etc.
  • the form of the last is always the same as an essential advantage; the patient will find the optimal fit for each foot in these shoes.
  • FIG. 1 shows in the left hand of the orthopedic shoemaker a plaster cast 2 cut from the patient's foot in the manner of an insert. The forefoot area 2.1 of the plaster cast is removed.
  • the last 1 is a standardized raw last, provision is made in the event that the patient's foot is wider than the raw last. This is shown in Fig. 2.
  • a hardening plastic mass 12 is applied to the strips 1.
  • the plaster cast 2, which was previously coated with a suitable release agent, is placed on this. In this way, the sole surface of the last 1 receives an exact image of the rear foot shape of the patient without any effort.
  • a footbed or insert is applied.
  • This can be designed as a half-long foot bed 13, as can be seen clearly in FIG. 7; but it can also extend over the entire length of the sole.
  • the rear foot area 3.1 of a standardized insole 3 is then marked on the free upper side of the footbed. This process is shown in Fig. 3.
  • Any lateral protrusions of the foot bed are appropriately maneuvered, i.e. H. progressively aligned.
  • the rear foot area 3.1 of the insole 3 is standardized.
  • the border to the forefoot area 3.2 is roughly marked by the dividing line 3.4.
  • the insole 3 is kept wider than the last 1 in order to have sufficient insole material for over-legs, ball extensions, etc.
  • the protrusions 3.3 of the insole 3 in the forefoot area 3.2 are trimmed according to the shape bar shape.
  • the trial shaft 5 consists of an inexpensive plastic material on a textile basis.
  • the stamped shaft size is used to order the final leather shaft and other matching shoe parts from the manufacturer.
  • the individual production of shoe parts as in conventional orthopedic shoe technology can largely be dispensed with, without the individual adjustment of the made-to-measure shoe, which is important for the patient, suffering as a result.
  • the orthopedic shoemaker can check the exact fit on the patient's foot in advance and correct it if necessary. Markings can be made directly on the trial shaft 5. With the help of these markings, the last 1 is then corrected if this should be necessary.
  • the strip 1 can also be covered on its upper side with a plastic film 14 in the deep-drawing process.
  • This film acts, for example, as a separating film, as will be described with reference to FIG. 7.
  • the release film 14 is cut, either as a forefoot cap 14.1 or as a rearfoot cap 14.2.
  • FIG. 7 shows a number of applications of the separating film 14 cut as forefoot cap 14.1.
  • a reinforcement 11.1 increases the shaft width, as is necessary for the production of boots.
  • a reinforcement 11.2 serves to adapt to a strong expansion of the patient's balls.
  • a reinforcement 11.3 is used to adapt to the patient's hammer toes.
  • the separating film 14 separates the reinforcements 11 from the last 1, the last 1 can be separated from the shoe Forefoot hats 14.1 are made with reinforcements 11. These are then removed from the shoe. As a result, there is no danger in the conventional technique of executing a last with strong ball or hammer toe extensions 11.2, 11.3 that the leather is overstretched and damaged.
  • the separating film 14 with the reinforcements 11 applied on the outside offers the possibility of using a single pair of lasts to manufacture both loafers and - after the application of a separating film 14 with the reinforcements 11.1 - boots for the patient. In this way, the creation of a second pair of lasts with the necessary work to adapt to the patient's foot shape is avoided.
  • the method according to the invention enables an improvement of the fit and a multiplication of the fashionable design options of the last and thus of the shoes and, as a result, a relief for the patient, an increase in the range of models and colors from which the patient can choose, in advance knows the final appearance of the shoe, a rationalization both in the production of the last and in particular the made-to-measure shoes as well as in the stock keeping and finally a cheapening of the shoe production through the possibility of prefabricating certain parts of the made-to-measure shoe in series.
