The invention relates to a blank for the production of an orthopedic shoe insert. On the sub-orthopedic shoe insole with a shaped side of the blank, a reinforcement 7 is embedded in a corresponding recess pressed body made of flexible base material and with a ring a resilient one supporting the longitudinal arch of the foot is not only used for support in a conventional manner Reinforcement made of deformable material, which is embedded in that of the longitudinal arch of the foot, but rather on the basis of a verrei base material. 35 at the front end of the blank also as a support

In another known shoe insert (DE-PS 45 being more or less flat or already in 8 54 692) a reinforcement of two leaf springs, which are held together longitudinally and / or transversely by a screw, is provided in an exercise. For this purpose, the reinforcements 6 sheath made of leather together with further support bodies and / or 7 are appropriately deformed, arranged pern. Here, too, the reinforcement extends only in the area of the longitudinal arch of the foot, depending on the orthopedic situation at hand. 50 units is made from the blank z. For example, by tapping an adaptation of the resilient reinforcement at a loading desired height of the reinforcement 7 and / or 6 nachstimmte foot shape must characterized träglich worked out In this way, a take place in that the two leaf springs interchanges bridge-like structure in complicated manner, which in moves essentially only or within the leather case, with its front area and the rear heel but not part of the shape of the individual leaf springs resting on the inner sole of the shoe and being slightly altered. see different shoes being exchanged

The basic material for the body of the blank is a material that can be shaped by pressing or casting, preferably press kneading cork mixed with nylon, rubber or latex, elastic plastics, Light rubber or the like. These materials can be shaped in conventional presses with two Mold halves take place with the application of pressure and, if necessary, heat.

The reinforcements 6, 7 can be made of Meiall, in particular steel or duralumin, plastic, in particular Nylon, or synthetic wood. In addition to leather, the cover 8 can also be made of plastic or cork.

The blank according to FIG. 1 to 3 can (in itself be is known and therefore not specifically shown) a coating on the top and / or bottom, in particular made of leather, plastic, lacquer or textile material a fen or bending adapted blank are applied, if this is desired in the individual case.

With the in F i g. 4 and 5 illustrated embodiments of blanks for the production of orthopedic Shoe inserts are one-piece longitudinal and transverse reinforcements 21 on the upper or lower side of the insert or 22 embedded in a flexible base material 23 of the type described above. The reinforcements 21, 22 are each covered by a cover 24 or 25. Furthermore, a conventional transverse arch support 26, e.g. B. glued on from elastic plastic, rubber or the like. Also from the blanks according to FIG. 4 and 5 can be laterally knocked or bent longitudinally and Work out transverse arch supports of any height adapted to the respective foot.

The reinforcements 6, 7, 21 and 22 described can also consist of a grid-like material, in particular perforated sheet metal, which is uncovered on the top or bottom of the blank. can be embedded and merges smoothly at its edge into the rest of the body of the blank

With all shoe insoles produced according to the invention, it is possible to do so afterwards and at any time to make further deformations due to the embedded reinforcement, so that foot anomalies through corresponding change in the shoe insert can be gradually healed. As shown in FIG. 1, the cover 8 is usually larger than that Reinforcements 6, 7 are formed and overlap them on all sides. As a result, the cover forms a resilient one Transition from the reinforcement to the base material of the blank.

The blanks according to the invention are pressed into the desired shape during their production so that they get a smooth surface and underside. Regrinding on the grinding machine is no longer necessary. All you need is the embedded, resilient ones Reinforcements can be brought into the desired shape by hammering or bending.

The blanks can be supplied with flat or curved reinforcement.
