DETAILED DESCRIPTION

(5) FIG. 1A shows a top view of a right shoe with an orthopedic shoe sole 1 according to the present invention, for persons with hallux valgus. The orthopedic shoe sole 1 according to the first embodiment of FIG. 1A supports the entire foot from Digitis Pedis I to V to the heel when walking or in a static state. The shoe of FIG. 1A comprises the orthopedic insole 1 according to the invention and an upper part 2, which preferably consists of an elastic material. Furthermore, the shoe is expediently open at the front to allow relative movement between the Digitis Pedis I and the Digitis Pedis II to V as described below. Alternatively, the shoe could have a corresponding free space for the relative movement.

(6) The foot of the wearer of the shoe is represented by a dashed line in FIG. 1A.

(7) The orthopedic shoe sole 1 of the shoe of FIG. 1A comprises a main part 14 and an element 3 movably connected thereto. The movable element 3 is located under and supports the Digitis Pedis I, while the main part 14 is located at least under and supports the Digitis Pedis II to V and the ball of the foot. According to the first embodiment example of FIG. 1A, the main part 14 supports the foot in the area of the Digitis Pedis II to V up to the heel.

(8) The movable element 3 is movably connected to the main part 14 via the connection 5. The relative movement between the movable element 3 and the main part 14 is ensured, for example, by the elasticity of the material used and can be supported by the indentations in the form of roundings 6. In particular, the roundings 6 prevent cracking due to stretching processes caused by the relative movement between the movable element 3 and the main part 14. The connection 5 between the movable element 5 and the main part 14 may be formed in one piece, so that both are made from the same basic piece, or a subsequently manufactured connection 5, so that both are manufactured separately and subsequently connected.

(9) The connection 5 between the movable element 3 and the main part 14 is designed in such a way that the movable element 3 can rotate about an axis 5 in a horizontal plane within the limits of the joint of the Digitis Pedis I and the ball of the foot. The axis of rotation 5 is preferably located in the area of the joint of the Digitis Pedis I (big toe joint).

(10) FIGS. 1B and 1C show sectional views along lines A-A and B-B, respectively, of FIG. 1A. As can be seen in particular from FIGS. 1B and 1C, a cavity 7 is located in the front area of the main part 14 of the shoe sole 1, in particular under the Digitis Pedis II to V. According to the first embodiment example of FIG. 1B, a hydraulic device is installed in this cavity, which is connected to the movable element 3 and causes the rotational movement in the horizontal plane laterally away from the main part 14 during a walking movement, in particular caused by the compressive force caused by the patient's own weight on the orthopedic shoe sole 1.

(11) The hydraulic device comprises, for example, an elastic sheath 8 in the cavity 7. This sheath 8 is filled with a gel or other fluid 9. On the side adjacent to the end face of the movable element 3, the sheath 8 comprises a plunger 10. This plunger 10 is designed, for example, as a corrugated tube, the tube profile being in particular in the form of a thread. In this case, the plunger 10, in particular the corrugated tube, is made of a material which has a higher strength than the elastic sheath 8. The closed end piece 11 of the plunger 10 is connected to the movable element 3. The hydraulic device thus formed is periodically actuated by the pressure exerted by the foot at the beginning of each step, in particular a pressure is exerted on the elastic sheath 8, causing the plunger 10 to move the movable element 3 relative to the main part 14 and causing the rotary movement in the horizontal plane laterally away from the main part 14.

(12) A compression spring can be inserted into the plunger 10, in particular the corrugated tube, in order to adapt the mechanical properties of the hydraulic device, in particular to generate a preload. This allows the pressure required to generate the relative movement between the movable element 3 and the main part 14 to be adapted to the individual needs of a patient.

(13) It is expedient to have an elevation 12 on the side of the movable element 3 facing the Digitis Pedis II, which ensures that the Digitis Pedis I can be moved with the movable element 3. Accordingly, the main part 14 can have an elevation 13 on the side towards the Digitis Pedis I, which fixes the Digitis Pedis II and thereby also the Digitis Pedis III to V on the main part 14. The elevation 12 of the movable element 3 and the elevation 13 of the main part 14 are shown in detail in FIG. 1C. Instead of the elevation 12 and/or the elevation 13, a bracket, a loop or the like can also be used to fix the Digitis Pedis I on the movable element 3 or at least the Digitis Pedis II on the main part 14.

(14) When walking, the heel of the foot lifts and the toe of the foot comes into a horizontal position and the entire weight of the person presses on the elastic sheath 8. The plunger 10 expands and spreads the movable element 3 to the side. The elevation 12 on the movable element 3 ensures that the Digitis Pedis I moves together with the movable element 3. During each step, the Digitis Pedis I thus simultaneously performs a movement in two planes, namely in the vertical plane together with the other Digitis Pedis II to V and a sideways splaying/pendulum movement in the horizontal plane together with the movable element 3 away from the Digitis Pedis II to V. When the compressive force is no longer applied, the movable element 3 and the Digitis Pedis I return to their initial position.

(15) If the person remains standing on the tips of the feet, the pressure is permanently applied to the hydraulic device and the movable element 3 spreads the Digitis Pedis I correspondingly from the Digitis Pedis II to V during this time, which also corresponds to a remedial gymnastic exercise for hallux valgus patients.

(16) The specific method of use, the frequency and amplitude of relative movement of the movable element 3 are specified by physician, especially orthopedists.

(17) FIG. 2A shows various views of a shoe according to a second embodiment of an orthopedic shoe sole 1 according to the invention. The second embodiment of FIG. 2A differs from the first embodiment of FIG. 1A in that there is no hydraulic device installed in the cavity 7, which is connected to the movable element 3 and causes the rotational movement in the horizontal plane laterally away from the main part 14 during a walking movement, but a mechanical device which is connected to the movable element 3 and causes the rotational movement in the horizontal plane laterally away from the main part 14 during a walking movement.

(18) The mechanical device according to the second embodiment of FIG. 2A comprises a leaf spring 15 having end portions 16. The leaf spring 15 is connected with the right end section 16 to the main part 14 of the shoe sole 1 via the connecting element 17. At the joint between the main part 14 and the movable element 3, the leaf spring 15 is inserted in a groove 18 of the movable element 3 and is connected to the movable element 3 by the axis 19. The leaf spring 15 has an elongated hole 20 for the axis 19 in the end portion 16 which is connected to the movable element 3, so that the offset of the axis 19 which occurs during the swinging/pendulum movement of the movable member 3 can be compensated. Details of this can be seen in particular in FIGS. 2D and 2E, which show sectional views along the lines C-C and D-D, respectively, of FIG. 2A.

(19) The leaf spring 15 has an upwardly curved region 21, as can be seen in particular from the sectional view of FIG. 2B, where FIG. 2B shows a sectional view along the line A-A of FIG. 2A. The upwardly curved region 21 of the leaf spring 15 presses from below against the upper plane of the cavity 7, as shown in FIG. 2B.

(20) On the movable element 3 there is an elevation 12 and on the main part 14 there is an elevation 13, corresponding to the first embodiment example of FIG. 1A, which fix the Digitis Pedis I or the Digitis Pedis II to V during the relative movement between the movable element 3 and the main part 14.

(21) FIG. 3A shows various views of a shoe with a third embodiment of a shoe sole 1 according to the invention. FIG. 3A shows a top view of a right shoe with the orthopedic shoe sole 1 according to the present invention, for persons with hallux valgus. The orthopedic shoe sole 1 according to the third embodiment of FIG. 3A supports the entire foot from Digitis Pedis I to V to the heel when walking or in a static state. The shoe of FIG. 3A comprises the orthopedic insole 1 according to the invention and a top 2, which is preferably made of an elastic material. Furthermore, the shoe is expediently designed to be open at the front in order to flexibly adjust the distance between the Digitis Pedis I and the Digitis Pedis II to V as described below. Alternatively, the shoe could have a corresponding free space for the adjustment.

(22) The foot of the wearer of the shoe is represented by a dashed line in FIG. 3A.

(23) The orthopedic shoe sole 1 of the shoe of FIG. 3A comprises a main part 14 and an element 3 movably connected thereto. The movable element 3 is located under and supports the Digitis Pedis I, while the main part 14 is located at least under and supports the Digitis Pedis II to V and the ball of the foot. According to the third embodiment example of FIG. 3A, the main part 14 supports the foot in the area of the Digitis Pedis II to V up to the heel.

(24) The movable element 3 is movably connected to the main part 14 via the connection 5. The relative movement between the movable element 3 and the main part 14 is ensured, for example, by the elasticity of the material used and can be supported by the indentations in the form of roundings 6. In particular, the roundings 6 prevent cracking due to stretching processes caused by the relative movement between the movable element 3 and the main part 14. The connection 5 between the movable element 3 and the main part 14 may be formed in one piece, so that both are made from the same basic piece, or a subsequently manufactured connection 5, so that both are manufactured separately and subsequently connected.

(25) The connection 5 between the movable element 3 and the main part 14 is designed in such a way that the movable element 3 can rotate about an axis 4 in a horizontal plane within the limits of the joint of the Digitis Pedis I and the ball of the foot. The axis of rotation 4 is preferably located in the area of the joint of the Digitis Pedis I (big toe joint).

(26) In contrast to the first embodiment of FIG. 1A and the second embodiment of FIG. 2A, in the third embodiment of FIG. 3A, the movable element 3 is connected to the main part 14 of the sole 1 of the shoe via a plate 22, which allows the movable element 3 to be locked away to the side with respect to the main part 14 of the sole 1 at different spreading angles, as shown for example in detail in FIG. 3B.

(27) The plate 22 is connected to the main part 14 at one end via a first pin 23. The first pin 23 is locked, for example screwed, from below through an opening in the main part 14 of the soleplate 1 into a first bulge 25 of the plate 22. At the other end, in the region of the movable element 3, the plate 22 has a second bulge 26 for a second pin 27. The movable member 3 of the sole 1 has a plurality of openings 24 for the second pin 27, so that the second pin 27 can be passed through one of the openings 24 and locked in the second bulge 26. The distance between the main part 14 and the movable element 3 is thereby adjusted by the choice of the opening 24 through which the second pin 27 is locked in the second bulge 26.

(28) The Digitis Pedis I is thus fixed by the fixed movable element 3 at a certain distance from the Digitis Pedis II supported on the main part 14, whereby a vertical movement is generated by the walking movement (bending of the foot), which also generates a remedial gymnastic movement that can be regularly adjusted by a physiotherapist, for example, due to the different adjustable positions. This is particularly advantageous if a simultaneous horizontal and vertical movement is too painful for the patient.
