Abstract

To produce custom-made orthopaedic shoes, a plaster cast (2) is first taken in the correction or bedding mould of the rear foot of the foot sole of the patient. Then the bedding mould (1.1) required is shaped to a rough last (1). Subsequently, a plastic film (4) is drawn over the sole and side surfaces of the last (1) and a foot bed (13) and cut in the manner of a sole with a rear cap (4'). A trial shaft (5) is pulled over the last (1) and lasted and glued to the plastic film (4), so that a trial shoe is produced. Under this, a heel (6) is fastened. After trial by the patient, the last (1) is if necessary corrected. Finally, on the corrected last (1), with the aid of a prefabricated leather shaft, the size and shape of which are determined using the trial shaft (5), the custom-made shoe is finished. The time-consuming transfer of the last shape to the leather with the aid of paper templates etc. is eliminated completely. Use can be made of shoe parts, in particular insoles (3), front and rear caps, leather shafts, outsoles, heels (6), eyelets, shoelaces etc., which are prefabricated in series production and matched to one another. As a result, high rationalisation, excellent fit and modern fashionable appearance are ensured. <IMAGE>

Description

The invention relates to a method for producing orthopedic bespoke shoes according to the preamble of Claim 1.

The care of feet suffering from tread and stress orthopedic bespoke shoes, e.g. B. in rheumatism, hallux valgus, open ulcer, calluses, scarring, spreading, Claw, hollow feet, etc. requires a lot of time because all components, including the strips, single or Custom-made products are high and therefore high for manufacturing Require time.

It is important first of all that the last is as exact as possible The patient's foot shape is adjusted. This task is currently difficult to solve because of the known Copy-milling processes used in mold and mechanical engineering are used in the manufacture of bespoke shoes the orthopedic shoemaker must leave. Come in addition, that the shape of the foot changes depending on whether the Patient is sitting, standing or walking.

The next problem then arises when transferring the Last shape on the pattern for making the Leather shaft, not only the size, but also one elegant or at least pleasing model form considered shall be. This work is done in the footwear industry by trained modelers done. The employment of Modelers in the production of custom-made orthopedic shoes is out of the question for cost reasons.

The last problem then is the manufacture of the Bespoke shoe itself Necessary insoles, upholstery and bedding received mostly in the past  shapeless and therefore inelegant appearance. This However, the problem point was largely satisfactory solved by that described in DE-PS 32 01 488 Process for the production of insole-free shoes.

The present invention is based on the object Specify the method of the type mentioned, which the Orthopedic shoemaker from those with shoe manufacture relieves associated ancillary work and enables him to concentrate entirely on the work on the patient, which in particular the precise manufacture of the last and the custom shoe eased and accelerated and which the use of factory-made finished parts allowed.

This problem is solved by a method with the characterizing features of claim 1.

The method according to the invention begins with the production of a plaster cast, especially under Using plaster bandages, what is in orthopedics to others Has been known for a long time. With the help of this negative plaster cast, the patient's foot shape becomes exact transferred to the last by using either material there removed or with the help of hardening plastic masses is added.

Standard strips are preferably used as strips, For example, a folding bar use that in the Technology is copied from the industrial moldings. Allows However, this was only realized by the knowledge that the 80% of actual foot deformities in the forefoot area occur so that standards of the rearfoot area on all Production parts are possible, as is standardization of the Insoles in the heel area to the ball of the foot, a standardization of the Heels, a standardization of the soles, a standardization of the Heel caps and the resulting standardization of the  Shafts.

As soon as the customized Patient strips is completed, preferably with Using the thermoforming technique a plastic film over the Sole and side surfaces of the last pulled and then cut out so that a kind of sole with The rear cap remains.

The most important intermediate step is above the last Test shaft drawn and on the cut Plastic film tweaked and glued. After another paragraph has been glued on, the resulting test shoe can be dated Patients are attracted. The fit can be control, namely while sitting, standing and especially Go. Any corrections can be made directly on the trial shoe be marked; the trial shoe can also be used cut open to make the exact position possibly necessary Check upholstery, rolling aids and the like. After re-listing the trial stem, the Transfer the displayed corrections directly to the last, see above that errors are practically impossible.

If the trial stem is already the one the patient wants Shoe model is quilted accordingly, the patient can already differ from the final appearance of his Make a custom shoe. Nevertheless arise from the Manufacture of the trial shoe using Plastic instead of leather only minimal costs, but through the ability to customize both the fit and the look of the final made-to-measure shoe before it is manufactured to be able to control by far.

Even now, even in particularly problematic ones Cases trial shoes made from cheap leather lining. However, these could change the appearance of the finished custom shoe  under no circumstances give a sufficient guess as they could not be modeledly similar to this.

Even in the final production of the actual one Custom shoe on the controlled and if necessary revised lasts the use of Trial shops that, as already mentioned, from inexpensive Plastic material, especially fabric-based, modelically the final bespoke shoe in all others Details correspond, good help. The Master orthopedic shoemaker only takes that long To keep trial shafts on the lasts as a fit check, until everything "fits". Only then does he take the real one Shoe manufacturing using the appropriate Leather shaft in attack. The time-consuming and often inaccurate Transfer the last shape to the leather with the help of Paper stencils etc. are completely eliminated, as is that Stitching together the different leather parts etc.

The trial stocks and also the final leather stocks can even be factory-made in larger quantities be, which has another rationalization effect with corresponding cost savings results. The price for Modeling, cutting, sharpening, bending, stepping, etc. spread over a larger number.

It is therefore possible to create a modular system in all for the production of the custom-made orthopedic shoe required components are included prefabricated.

The deep-drawn plastic films already mentioned above can not only on the sole surface, but also on the Use the top of the last. This is for example, advantageous if for a patient not only made low shoes, but also boots etc. should be known to be a larger clamping and  Heel width need as low shoes. On the plastic film is hardened with the help of the already mentioned Plastic mass made the appropriate padding. Thanks to the plastic film as a separating layer, they can Refills can be easily removed as soon as again a low shoe is to be manufactured. This makes it unnecessary the production of several strips for one patient.

Finally, there is still the possibility of attaching before of fillings the standard lasts with the To wrap plastic film as a separating layer. That’s it possible, first only the last and only then the To remove padding from the shoe. This is for example, advantageous if for a patient very strong padding, for example for hammer toes, Bale extensions and the like are required. In Until now, orthopedic shoemakers have had to deal with such problems As a precaution, cut the shaft seams to avoid tearing the To prevent the shaft from sticking out.

Based on the drawing, the invention in the form of Embodiments are explained in more detail. Show it each in a schematic representation

Fig. 1 shows a listed test shoe and

Fig. 2 shows a listed boot shaft.

A strip 1 in the form of a folding strip with parting surface 2 and fastening bore 3 can be seen in a semi-transparent representation in FIG. 1.

This factory last 1 is adapted to the individual foot shape of the patient by removing and / or adding material, for example a hardening plastic mass, for which purpose a previously made plaster cast is used.

On the sole and side surfaces 1 'of the last 1 , a thermoforming film 4 is formed and cut out so that a kind of insole with a rear cap 4 ' is formed. On this plastic film 4 , 4 ', a trial shaft 5 is tweaked and glued. The standard test shaft 5 corresponds to the model of the desired custom shoe, but consists of an inexpensive plastic film material, in particular on a textile basis. A trial heel 6 completes the trial shoe thus produced, which is tried on by the patient after being carried out.

After the result of the try-on, the last 1 is then possibly revised and the actual custom shoe is then produced. Trial shops are used to select the leather shaft. These are held on the last 1 until the suitable size is determined, on the basis of which the leather shaft which has been prepared accordingly is then determined.

Fig. 2 shows the production of a boot using a last 1 , as it was created for the production of low shoes. As is well known, boots need a larger shaft width than low shoes.

For this purpose, a plastic film 14 is first deep-drawn as a separating layer over the strips 1 . Then padding 11 made of hardening plastic is applied. After the already described precursors of preparing leather shaft 15 on the last 1 or stitched to the sole surface 1 'of the last 1 is then insole (not shown in the drawing) tweaked and glued.

Thanks to the plastic film 14 as a separating layer, these fillings 11 can be removed again as soon as a shoe is to be produced. In this way, the creation of a second set of last with the necessary work of adapting the sole and side surface 1 'to the foot shape of the patient is avoided.

Overall, the method according to the invention enables one Increase in fit and a related one Relief for the patient, an enlargement of the Offer of models and colors under which the patient can choose, with the final appearance in advance of the shoe, a rationalization of both Manufacture of lasts and especially bespoke shoes also when it comes to stockpiling and finally a reduction in price of shoe making through the possibility of certain parts prefabricate the custom shoe in the factory.
