    Description

    [0079] The invention and the technical field are explained in more detail below on the basis of the figures. The figures depict particular embodiment variants, although the invention is not restricted to them. In particular, it should be noted that the figures and the relative sizes illustrated therein are only schematic. In the figures:

    [0080] FIG. 1: shows a first sectional view through a casting mold for producing an orthopedic support element,

    [0081] FIG. 2: shows a second sectional view through a casting mold for producing an orthopedic support element,

    [0082] FIG. 3: shows a sectional view through a further casting mold for producing an orthopedic support element,

    [0083] FIG. 4: shows a sectional view through yet another casting mold for producing an orthopedic support element,

    [0084] FIG. 5: shows a sectional view through a further casting mold for producing an orthopedic support element,

    [0085] FIG. 6: shows an orthopedic support element in the production shaping, and

    [0086] FIG. 7: shows the orthopedic support element from FIG. 6 in the therapy shaping.

    [0087] FIG. 1 shows a sectional view through a casting mold 5 for the production of a described orthopedic support element, this casting mold being formed from an inner mold 3 and outer mold 4. In this case, the outer mold also has runners 15, which assist the casting process for producing the orthopedic support element. Illustrated in the casting mold 5 according to FIG. 1 is the casting material 6, from which the orthopedic support element is produced. Through these runners 15, for the one part the casting material 6 for producing the orthopedic support element can enter the casting mold 5. For the other part, through such channels gas can leave the casting mold 5 when the casting material 6 enters the casting mold 5.

    [0088] FIGS. 2, 3 and 4 show a schematic cross section of casting molds 5 according to FIG. 1. Also illustrated here is the overlapping portion 2. The overlapping portion 2 is formed by a mold portion 27 predefined by the outer mold 4. Adjoining the overlapping portion 2 is the transitional region 8, in which a transition from the inner mold 3 to the outer mold 4 is formed. In the transitional region 8, the mold portion 27 rests against the inner mold 3. The mold portion 27 predefines a first open end 22 and a second open end 23 of the orthopedic support element, or of the casting mold 5, at a distance 24 from one another. The casting mold illustrated in FIG. 2 has three parts, with an inner mold 3 and an outer mold 4 which in turn consists of a first part 9 and a second part 10. The casting mold 5 predefines a first (inner) side 11 and a second (outer) side 12 of the orthopedic support element. These two sides are opposite one another in the region of the overlapping portion 2. The mold portion 27 is between these two sides.

    [0089] FIG. 3 and FIG. 4 show sectional views through two further, different casting molds for the described method. Also visible here in each case are the inner mold 3 and the outer mold 4. Each outer mold here consists of multiple parts, specifically a first part 9, a second part 10 and a third part 13. The outer mold 4 and the inner mold 3 together form a cylindrical (helical) hollow region, which is filled with the casting material 6 in order to produce the orthopedic support element. An overlapping portion 2 of the orthopedic support element is formed by the outer mold 4. The orthopedic support element overlaps itself in this overlapping portion. A first part 9 of the outer mold 4 in this case determines the shape of a first side 11 of the overlapping region 2. A second part 10 of the outer mold 4 determines the shape of a second side 12 of the overlapping region 2. The third part 13 is arranged on that side of the inner mold 3 that is opposite the first part 9 and the second part 10. The first part 9 and the second part 10 together form a half shell of the casting mold 5, while the third part 13 forms the other side of the casting mold 5.

    [0090] FIG. 4 shows, as a special feature and by way of example, that inlays 14 are inserted in the casting mold 5, which are encased by the casting material 6 during the casting process in step c).

    [0091] FIG. 5 shows an adjustment means with the inner mold 3 and outer mold 4 being arrested relative to one another. Shown here, for example, is a recess 21 in the outer mold 4 and a stud 20 on the inner mold 3.

    [0092] FIG. 6 shows a finished orthopedic support element 1, which was produced according to the described method, in a manufacturing shaping 25, which in particular corresponds to the form predefined by the casting mold. As a result of the production method, ventilation means 16, decorations 16, closure elements 18 or other fixtures, and individualizations and identifiers 19 can be provided on the orthopedic support element without problems. In FIG. 6 it is possible to see, in three dimensions, the overlapping portion 2 in which a first open end 22 and a second open end 23 of the orthopedic support element 1 overlap. In the manufacturing shaping, there is a distance 24 between the first open end 22 and the second open end 23.

    [0093] FIG. 7 shows the orthopedic support element 1 according to FIG. 6 in a therapy shaping 26, although the body part to be treated is not illustrated here. The therapy shaping 26 and the manufacturing shaping 25 differ in that the first open end 22 and the second open end 23 rest against one another, and accordingly without a distance 24 between them, in the therapy shaping 26.
