Definitions

• the invention relates to an orthopedic shoe
• Shoes which are difficult to adapt to the corresponding foot size due to their design, are to a certain extent adjustable. This procedure is in particular especially widespread in ski boots, in which the outer shell cannot be manufactured in any size range and thus the inner boot must be suitably sized, for example by raising the sole, as is known from US Pat. No. 4,765,070. However, such adjustable size shoes are not suitable for orthopedic purposes.
• the invention is based on the problem that, especially due to the strong sporting activities of the wider population, many athletes have discomfort when walking or running, which in most cases has not yet reached a level of damage that makes orthopedic treatment seem appropriate. It turned out that many of these complaints are not due to orthopedic reasons, but to athletic overloading of the patient. A typical example of such complaints is inflammation of the Achilles tendon, which is similar to that known from the prior art. Gowns are not yet satisfactorily curable.
• the invention has for its object to provide an orthopedic shoe which, with a simple structure and easy, universal applicability, enables the complaints to be reduced or cured when walking or running.
• a tread plate is arranged at least in a footprint, which is adjustable relative to the sole of the shoe.
• the invention is based on the basic idea that the complaints which occur, for example, in Achilles tendon inflammation are caused by the fact that the patient places an incorrect load on his foot or, particularly in the case of some special types of movement, in an unfavorable manner on one usual shoe supports. It can happen that the patient loads his foot correctly during normal walking, or at least an incorrect load does not occur to such an extent that an orthopedist could immediately determine this during an examination. With a higher level of physical exertion, for example with a high running load or with frequently changing loads when playing ball or the like, it is possible that the incorrect load on the foot reaches a level that causes considerable discomfort, be it because of incorrect strain on the tendons, especially the Achilles tendon, and incorrect loading of the joints causes inflammation. Incorrect strain in the musculoskeletal system is known to cause pain in the range of
• the principle on which the present invention is based is based on arranging a step plate on at least one contact area of a foot which is adjustable relative to the sole of the shoe.
• the adjustability of the step plate has the advantage that the usual sole of the shoe, for example a profiled sole of a sneaker, does not need to be changed. It is therefore possible to use shoes that are customary in the sole area, in particular sports shoes. Since the step plate, on which at least part of the patient's weight rests, is adjustable relative to the sole of the shoe, it is possible to balance it in such a way that even under athletic stresses of the patient there are no incorrect loads on the
• Another advantage of the shoe according to the invention is that the adjustment of the tread plate can be done in any way, so that the patient can determine a position that is favorable for him by simply trying it out or by brief instructions. Since experience has shown that even the smallest adjustment paths are sufficient to adjust the To alleviate or completely heal any complaints that arise, the adjustable shoe according to the invention represents a considerable advantage over orthopedic shoes which were manufactured according to the information of a doctor. If it turns out with such a known shoe that the adjustment has not been carried out in an optimal manner, the patient will continue to have considerable complaints, which can only be remedied by expensive modifications to the shoe or new production of orthopedic shoes. In contrast, the shoe according to the invention is easy to adjust and can be changed at any time.
• the shoe according to the invention thus makes it possible to alleviate or cure a large number of complaints, and adaptation and adjustment can in particular be made even when minor complaints occur, without having to wait until the complaints reach a certain level and an examination is carried out by an orthopedic surgeon. On the contrary, the shoe according to the invention enables an adjustment which has a prophylactic effect on possible complaints.
• the tread plate can be tilted about two axes which are arranged essentially in the plane of the tread plate and which are essentially perpendicular to one another.
• the tread plate can be adjusted around two axes.
• this embodiment is particularly well suited to compensating for most complaints, for example inflammation of the Achilles tendon.
• Another advantage of this adjustability is that the shoe continues to fit the wearer, that is to say that the shoe cannot be pressed by an incorrect adjustment of the sole area.
• the adjustability of the tread plate can be fixed in a favorable way in order to avoid an automatic adjustment even under heavy loads.
• the tread plate can be adjusted either via a screw mechanism or via a hydraulic mechanism, but it is also possible to provide pneumatic devices, for example air cushions, which support individual areas of the tread plate. Since it is only important according to the invention to adjust the tread plate relative to the sole, the adjustment mechanism and in particular the arrangement of the tilt axes play a subordinate role. The adjustment can be carried out by the average specialist taking into account the design of the respective shoe based on his specialist knowledge.
• the tread plate in the heel area, in the heel area or in both the heel and ball area of the shoe in order to provide support for the foot in such a way that it optimally corresponds to the anatomical conditions of the wearer.
• the tread plate both in the heel area and in
• the tread plate can also be adjusted in the vertical direction.
• this adjustability opens up the possibility of compensating for slight differences in length between the two legs of a patient.
• the tread plate is profiled to adapt to the shape of the foot and / or is provided with a footbed and / or is correspondingly coated with an upper sole.
• a further, particularly advantageous further development of the shoe according to the invention consists in that at least one edge region of the sole of the shoe is provided with a recess, preferably in the form of a rounding of the edge of the sole.
• This recess prevents, among other things, that the patient's foot is placed on edge areas of the sole which are not part of the anatomically correct footprint and therefore lead to incorrect loading when the foot is placed in the event of an unfavorable movement sequence when it is placed on the floor would.
• the foot or shoe can be placed on the floor in such a way that it optimally interacts with the correctly set up footprint.
• the tread plate it is possible to design the tread plate either in the form of a rigid plate, which can additionally be provided, for example, with a footbed.
• the tread plate in several parts or in multiple members, so that individual areas of the tread plate can be adjusted, ie tilted or raised, independently of the other areas.
• the tread plate elastic and to provide devices for lifting or lowering these areas under the individual areas of the tread plate.
• the shoe according to the invention can be used both for the healing of already existing complaints and as a prophylactic.
• the adjustment of the tread plate can either be carried out by the wearer himself, but it is also possible to make the adjustment on the basis of special measurements and / or in cooperation with a doctor.
• the shoe according to the invention is suitable for a wide variety of applications. Since neither the outer shape of the shoe nor its sole design has to be changed significantly compared to conventional shoes, the shoe according to the invention can be designed as a gymnastic or sports shoe and as a special shoe for certain sporting disciplines. Furthermore, it is possible to the invention appropriate shoes to be used in normal everyday life or when working.
• the positive results can be determined both heuristically and iteratively in a simple manner.
• Another important field of application of the shoe according to the invention is to increase the performance of the human body by precisely adjusting the forces and loads that occur. For example, it is possible to increase walking or jumping ability through such an optimal distribution of force and load.
• the shoe according to the invention thus opens up the possibility, either on the basis of a customarily sized one
• Shoe that can be worn in the usual way make an adjustment when complaints occur or provide the adjustability according to the invention for a shoe that is already designed in an orthopedic manner.
• the user for example a high-performance athlete, can use a shoe dimensioned in the usual way until complaints appear or indicate.
• the adjustability provided according to the invention makes it possible, without any particular effort, to balance the footprint of the foot in order to avoid peak loads and to alleviate or cure the symptoms.
• it is possible for a person who needs an orthopedic shoe for example because of deformities of the bone structure or because of injuries, to have it adjusted in the usual way by a medical professional, for example by improving the bone structure. Because a shoe made in this way is only rough Approximation can fit, it is possible according to the invention to adjust this shoe in an optimal way to the needs of the wearer by fine adjustment of the tread plate or the footprint of the foot.
