[0001] DESCRIPTION

[0002] Insoles with functional geometry

[0003] The present invention relates to a functional component of an insole, an insole, a method for manufacturing such a functional component and a method for manufacturing such an insole and a shoe or an orthopedic aid comprising such a functional component and a shoe or an orthopedic aid comprising such an insole.

[0004] Insoles are used for comfort, in sports, or for medical reasons, particularly orthopedic ones. The most common type of insole is the shoe insole, which is mass-produced industrially for various shoe sizes. Orthopedic insoles, on the other hand, are often custom-made to fit the specific area being treated, such as a patient's foot, according to the medical indication. Their purpose is to support the affected area or correct postural problems.

[0005] Common insoles, especially shoe insoles, have various components, such as a raised metatarsal pad for transverse arch support, longitudinal arch support, particularly for the medial edge of the sole, pressure-absorbing pads, pressure modulators, pressure bodies, or inserts. The individual components are usually bonded together, for example, by welding, fusing, or gluing.

[0006] Insoles, particularly shoe insoles, are also known to consist of various components made from materials of differing hardness. The production of such insoles, made from at least two materials, often employs a complex injection molding technique in which the softer material is injected into molds of the harder material. Following this injection molding process, the two materials are usually bonded together.

[0007] A material-bonded connection has the disadvantage that, after the production of such insoles, components can only be replaced or omitted with considerable effort, if at all. Furthermore, when manufacturing insoles with components made of two different materials, it is necessary to equalize the thickness of the materials by removing material from the surface.

[0008] Difficulties arise with this established procedure when, for the production of an insole, such as an orthopedically appropriate cushioning or support element, zones of higher or lower mechanical strength must be individually incorporated in specific areas of the insole to selectively enhance the cushioning or support function. This may be necessary, for example, in the area of ​​joint protrusions of the body part or joint to be supported, such as the heel or toe ball, ankle, wrist, patella, or tibial plateau at the knee joint, or similar structures. This necessitates additional manufacturing steps. For instance, it may be required that a core material be bonded to specific areas of its surface with a different cushioning material exhibiting different mechanical properties and / or with other components to enable the zoned or compartmentalized cushioning or support function of the insole.The production of well-known insoles made from multiple components is complex and expensive.

[0009] The invention is therefore based on the technical problem of at least reducing, and preferably overcoming, the disadvantages of the prior art, in particular providing a functional component of an insole or an insole that allows for individual customization, especially the quick and easy exchange of various components, particularly without complex process steps, as needed. The present invention is also specifically based on the technical problem of manufacturing the aforementioned insole simply and cost-effectively.

[0065] The inventive method makes it possible to produce a functional component of an insert or an insert according to the invention simply and cost-effectively, in particular more simply and cost-effectively than known inserts, especially those having a material-bonded connection.

[0066] In a preferred embodiment, step a) is carried out by means of thermoplastic deformation. Preferably, the base body and / or the shaped body is produced by means of thermoplastic deformation.

[0067] In a preferred embodiment, step a) is carried out in a temperature range of 80 to 200 °C, in particular 80 to 150 °C, in particular 120 to 140 °C.

[0068] In a preferred embodiment, step a) is carried out at a pressure of 0.15 to 0.9 bar or 4.0 to 7.0 bar, based on the absolute pressure, in particular where atmospheric pressure corresponds to 1 bar.

[0069] In a preferred embodiment, step a) is carried out at a pressure of -0.5 to -0.9, in particular -0.6 to -0.8 bar, relative to the relative pressure, in particular where atmospheric pressure corresponds to 0 bar.

[0070] In a preferred embodiment, step b) is performed using a water jet cutter, an oscillating knife, a milling cutter or a drill.

[0071] In a preferred embodiment, the waterjet cutter has an angle adjustment capability. In a preferred embodiment, the slope produced in step b) of the at least partially inclined first boundary surface of the at least one recess or at least one hole of the at least one layer of the base body has an angle of 1 to 179° to a perpendicular line located on the central longitudinal axis of the recess or hole, in particular on the surface enclosed by the boundary surface.

[0072] Preferably, the first boundary surface of the at least one recess or hole of the at least one layer of the base body and the second boundary surface of the at least one shaped body are in contact with each other and form a positive-locking connection. It is particularly preferable that a material-bonded connection, for example, gluing the edges, can be dispensed with.

[0073] Without being bound by theory, it can happen that the molded part and / or the recess or hole is deformed so significantly during thermoplastic forming, especially during deep drawing, that the actual position and function are not completely correct.
