Device for the manufacture of orthopedic
Insoles, e.g. footrests

The innovation "relates to a device for producing clay orthopedic insoles, eg footrests and the like. With which the foot is also molded, the device consisting of a box divided into two contiguous chambers", the upper chamber of which contains loose particles of small dimensions , for example balls, is filled and covered at the top by an elastic plate, and its lower chamber to a one
Vacuum generating device is connected. For the production of orthopedic insoles, e.g. footrests and the like, one ends standard forms made of aluminum, wood and the like,
between which the blank of the orthopedic insert is inserted. Then the upper and lower parts of the mold are put under pressure and in this way a standard setting

location shaped. For the individual adaptation of this standard form "considerable reworking is required, which is the finished Naturally increase the price of the product. In this way, it is also hardly possible to find an orthopedic orthopedic that complies with the standards in every detail Manufacture insert.

The innovation is based on the task of a device to show with which orthopedic insoles that are absolutely true to shape in a relatively simple and cost-saving manner can be produced. The innovation is characterized by the fact that the box has a frame and an elastic Plate of the existing cover is releasably connected, the elastic plate of which is "under pressure" between the the box and the lid "located cavity against a presses the kneadable mass introduced into the impression of the device.

Appropriately, the load takes place according to the shape of the impression by the pressure of the foot itself. It is in the frame The innovation, however, is also possible to apply the load according to the shape of the impression by means of a pressurized plate.

The device according to the innovation is based on the following the drawing explained in more detail. In this show in a purely schematic way:

Pig. 1 shows a vertical section through a filling device with introduced kneadable mass,

Pig. 2 shows a vertical section through an impression device with introduced, kneadable mass loaded by the pressure of the foot,

Mg. 3 shows a vertical section through a further embodiment of the impression device with introduced, kneadable mass loaded by the pressure of the foot according to the innovation,

Mg. 4 a vertical section through the device according to the innovation out of order,

Pig. 5 shows a vertical section through the innovation according to the invention Device in operation,

1 (Pig. 1) denotes a box which is filled in a known manner with a moldable material 2, for example plaster of paris and the like. The puss or pus part to be molded is pressed into this material, the material 2 solidifying after shaping.

According to the innovation, a kneadable mass 3, which is chemically or thermally deformable, is introduced into the impression of the device. Connections hlie ßend it is this

Material 5 ″, for example, loaded by the pressure of the foot 4 and thereby after. Shaped according to the imprint of the "device (Fig. 2). A material that solidifies within about five minutes is expediently used as the kneadable material. on in this way the desired orthopedic insert such as a footrest and the like is obtained.

3 to 5 is a somewhat modified device shown. The box i is closed in this case with an elastic plate 5 made of rubber and the like and divided into two contiguous chambers by an air-permeable layer 6.

The upper chamber is made of plastic with loose balls 7 or the like. Filled, while the lower chamber receives a negative pressure generating device 8, which with the help of a Foot switch 9 can be put into operation. Is expedient one of the two chambers is connected to the atmosphere via a ventilation valve not shown in any further detail in the drawing.

If an orthopedic insert is to be made, then the stripped foot is on the elastic plate 5 of the Device set. Subsequently, the foot switch and thus the device 8 generating a negative pressure are put into operation set. As a result, the chamber filled with the balls 7 is placed under negative pressure and thus a lifelike impression of the foot 4 or foot part reached (Fig. 3).

Then it will be renewed according to the imprint the device introduced a kneadable mass 3 (Mg. 4). Then the box Ί is hermetically sealed with a lid, which consists of a frame 10 and an elastic plate 11. The box 1 is connected to the lid expedient with the help of a quick lock. In connection then the cavity located between the box 1 and the lid is placed under negative pressure, which has the consequence that the elastic plate 11 under the influence of atmospheric pressure presses against the introduced mass 3 in accordance with the imprint of the device and thus the orthopedic insert forms. After curing has taken place, this insert can be removed from the device according to the innovation and without any reworking be used.
