pcmr: "Shape for a shoe and in particular for sports shoes".

The present invention relates to a form for a | shoe and in particular for sports shoes like | * tennis shoes, jogging or jogging shoes, shoes for excursions on foot 5 or mountain climbing shoes, gymnastic or indoor sports shoes, sports shoes | football or the like with an edge of the sole passing around it in the form of a closed ring, and defining the transition between the part of the sole and the part of | 10 the vamp, and where any two points, oriented i '1 perpendicular to the longitudinal axis of the shape, of the straight line connecting opposite zones of the edge of the sole, define a plane of the sole in space! the direction of which deviates from the direction in space 15 of the area of the outer sole of the form.

To help, with a shoe, to control the foot in a natural walking position at a distribution! optimal loads and resulting forces, with comfort.

satisfactory, it is known to manufacture a shape in which the sole area is adapted to the shape of the sole, which determines the shape of the insole so that the sole area is curved asymmetrically (refer to German Patent No. 1,953,656). By representing this known shape on polar diagrams by means of several sections which are placed vertically; at the longitudinal axes of the foot or of the shape, it can be seen that the shape, or the plane of its sole * and the area of the sole are sloping supine in practically all the planes of the sections. The term "supine" means, in the present context, a slope or twist of the straight line or plane relating to a right foot or shape looking from the heel, relative to a horizontal plane in the direction of the needles. 'a watch. Consequently, the term "pronation" indicates a slope or twist of the straight or flat line with respect to the horizontal plane in a counter-clockwise direction.

In the case of another known form (refer to the publication of Germanic patent No. 1 VIO 534), the parts of the forefoot and the hind foot are twisted 2 relative to each other. In the metatarsal area of the foot, the plane of the sole is horizontal while in the heel portion there is a slope in pronation and, in the area of the forefoot, a slope in supination.

5 In the case of a load pressing on the foot resting on the ground, the parts of the front foot and rear foot are restored in directions of rotation contrary to the respective load of corresponding quantities®, The area of the plant s' deviating from the plane of the plant or sole 10 'in its course in continuous space, in the area' of the forefoot, flat transversely to the longitudinal axis of the foot, while it is curved convexly in the direction of the pitch development line.

Even if the forms known in the joratic already impart better running support to the foot as a result of the anatomically correct reproduction of the shoe, it has nevertheless been found, in particular with sports shoes, that the control of the foot was frequently still inappropriate.

It is therefore an object of the invention to study a shape so that, in sporting activities, the risk of an outward sprain of the foot is prevented at a significant angle, while the foot must at the same time be supported particularly securely in the zone 25 of the point of pressure of the load pressing on the foot.

According to the invention, this object is solved because the straight lines defining the plane of the sole are oriented horizontally in the area of the heel and forefoot and are sloping supine in the metatarsal area and because in the area of the forefoot, in particular in the region of the great metatarsal eminence of the foot and the big toe, the plane tangential to the region of the sole is sloping in pronation relative to the relevant plane of the sole, 35 In the case of a shoe made on this new shape, the plane of the sole is oriented horizontally in the heel area. There is therefore no risk, even with sports activities, of a sprain of the foot outwards. The slope of the plane of the i • 3 supine sole in the metatarsal area produces a particularly reliable support for the longitudinal arch of the foot. From this point of view, the shape is preferably studied so that the transition from the horizontal direction of the (5 plane of the sole in the heel area to the slope in supination in the metatarsal area is offset far in the area of the heel and that the maximum slope pc in supination 1 of the metatarsal zone is arranged at the point of thrust of the load bearing on the foot. Consequently, the sup] _:> rt 10 for the longitudinal arch of the foot is located very far 'in the direction towards the heel. The support for the longitudinal arch is developed to its maximum in the zone of: point of pressure of the load bearing on the foot, and thus appreciably in the extension of the tibia. ; 15 of the pressure point, located approximately near the Coparth joint, a collapse of the longitudinal arch due to the load on the foot can thus be particularly effectively prevented.

In this area impact the structure of the bones, 20 the tendons to move the toes, which normally travel, like a rope, the longitudinal arch of the foot without any direct contact with the metatarsal bone. Because of this new type of support, the tendons however remain devoid of uransversal load, thus the foot will tire 25 monk quickly. Based on the new design, it produces a substantially spherical configuration of the heel envelope, which allows a gentle support of the ’heel, accompanied by a simultaneous widening of the support surface. The particularly good support of the i: ne; 30 metatarsal at the point of push of the che: -girt flirting on: * the foot has the additional advantage that 1? foot meets reliable resistance, in other lands, it 'practically cannot slide forward, so the toe area remains essentially away from one. : intact: '35 with the reinforcement piece.

In order to support the closed cross vault! foot, a metal support is preferably provided: .-. roien of corresponding shape having regular contours. The regular contours prevent pain when wearing the 4 shoe without affecting the support effect. On the form, the metatarsal support can be noticed by a recess of corresponding shape and clearly visible in the metatarsal area of the surface of the sole.

• 5 Preferably, the shape is studied so that, in the area of the forefoot, the surface of the sole is sloping in pronation relative to the plane of the sole. This becomes evident by a corresponding slope of a tangent applied jointly to the areas of the big toe 10 and the inner eminence as well as the outer eminence, which is sloping counterclockwise, in d In other words, in pronation, the big toe and the two eminences of the foot being located below the plane of the sole. The slope of the tangent advantageously lies at an angle of between about 2 ° and about 10 ° and which is preferably 5 ° - This shape corresponds to the natural twist of the foot. As a result, the support for the longitudinal and transverse arch already begins in the area of the eminence. Furthermore, the pronation slope of the anterior foot 2o aids in the natural rolling movement of the foot during its movement. As a result, the risk of a sprained foot can be further reduced. As a result of the setting in pif: that of the great eminence of the foot at a lower level, the sesamoid bones located below the metatarsal-25 phalangeal joint undergo an additional relief which one finds particularly pleasant in the port of the shoe.

Thus, the foot inside the shoe made on the new shape has more effective protection against sprain. Control inside the shoe is decisively improved by enlarging and adapting the support area of the sole of the foot. One important point to avoid is spacing between the insole and the sole. As a result, an upper is obtained at the same time which is also applied very precisely and uniformly on the foot, thus the foot cannot twist inside the shoe and it cannot likewise slip out of its correct position. . As a result of the shoe applying very precisely but nevertheless very comfortably, all the forces of the foot can be transmitted to the self; 5 practically without any loss, which is particularly important especially for sports shoes.

The present invention also relates to a shoe made on the new shape, in particular a sports shoe having, in comparison with known sports shoes, all the advantages described above in detail with reference to the shape.

The invention will be better understood, and other aims, 1.0 characteristics, details and advantages thereof will appear I 'more clearly during the explanatory description which î j will follow made with reference to the schematic drawings appended j. given only as an example illustrating a mode of! . embodiment of the invention and in which: FIG. 1 is a perspective view of the shape: according to the invention for a straight shoe, the view being directed towards the side of the shape corresponding to the inner side of the foot; "Figure 2 shows, in top view, the contour 20 of the shape at the plane of the sole; and; - Figures 3, 4, 5 and 6 respectively show cross-sectional views made through the shape of FIG. 1 and oriented perpendicular to the longitudinal axis of the form, the sections being placed along the planes 10, 11 of FIGS. 1 and 2.

The shape 1 illustrated in perspective in Figure 1 is intended for the manufacture of a shoe for the right foot „The tip of the shape is designated by the reference 2 and the end of the shape is designated by the reference 3 · 30 The shape has an upper zone 4 for the upper of the shoe and a lower zone defined by the surface 5 of the sole. The two zones abut along a separate edge 6 of the shape which corresponds to the edge of the sole of the shoe. The edge 6 of the shape or of the sole passing all around in the form of a closed ring defines the outline of the plane 9 of the sole illustrated in space. It is also defined by straight lines 10 oriented perpendicular to the longitudinal axis 13 of the shape and each connecting two opposite points of the edge 6 6 of the sole. In FIGS. 1 and 2, four of these straight lines 10 have been drawn connecting the pairs of points 10a, 10b from front to rear; 10c, 10d; 10th, 10f; and * 10g, 10h from the "edge 6 of the sole.

5 It can already be seen in FIG. 1 that the plane 9 of the sole oriented in space deviates markedly from the path in space of zone 5 of the sole. With the shape 1 illustrated in FIG. 1, which reproduces the shape of the foot, the area 5 of the sole of the shape is 10. identical to the area of the sole or the sole of the corresponding foot.

For the cooperation of the shoe and the foot, in particular in the case of sports activities, are essential the respective slopes of the straight lines 10 15 defining the plane 9 of the sole with respect to a horizontal plane, as well as the relative slope of zone 5 of the sole in relation to aro: zones in relation to plane 9. To make these relationships clear to the decisive zones of the form, the cross sections of the resulting form in the zone of straight lines 10 drawn in FIGS. 1 and 2, are shown in Figures 3 to 6, the perpendicular medians 11 on the related straight lines, which are shown in Figure 1, being intended to indicate the respective vertical position of the plane of the section or section c

Considering Figure 1 and Figure 5> can see that the plane 9 of the sole curved in space at its highest level substantially in the region of the plane in cross section according to Figure 5, that is to say - say in 30 the metatarsal zone 16. The straight line 10 connecting the v points 10e, 10f has, with respect to the horizontal plane 25, suggested by a dotted line in Figures 3 to 6, a slope in the direction of supination. The magnitude 24 of this slope with respect to the horizontal plane 25 is approximately '35' between 15 ° and approximately 45 ° and reaches this preference approximately 25 ° "In the heel zone 8, as well as in the zc -3 of the front foot, in particular in the area of the large ortet, and of the great eminence 7 of the foot, the straight lines 10 defining the plane 9 of the sole are, as in FIGS. 3, 7 4 and 6, on the contrary oriented parallel to the plane horizontal 25.

From the highest point 10e of the metatarsal zone 16 of the straight line 10 sloping in supination, 5 the "edge of the sole 6" drops along the foot inwards j to the heel zone 8 , up to the transition point of the metatarsal zone of plane 9 of the sloping sole in supination to the horizontally oriented zone of the plane of the sole at the level of the heel part 8. The zone Ί-0 of the sole between the straight line 10 passing through point 10e of FIG. 1 and the straight line passing through point 12 on the "edge 6 of the sole, passes close to the Coparth joint of the foot. In this zone corresponding substantially to the extension extension of the tibia, is placed the point of thrust of j. Ί5 the load bearing on the foot. Following the course in] the space of the zone between the points of the edges 10th and 12 j 'of the plane of the sole , the metatarsal area between these points! is supported reliably and thus the foot is also effectively maintained, lo rs of braking, against a] 20 sliding forward} towards the tip of the shoe.

3 \ j Due to the horizontal path of the straight line 10 j between the edges 10g and 1Ch of the sole according to the figure; 6, a substantially vertical support is obtained in the heel zone I 8.

! 25 It is true that the straight lines read from the pim of sole 9 pass horizontally mime in the area of 4; . forefoot as can be seen in Figures 3 and 4.

j It can however be seen in these figures that the great eminence î 7 of the foot, as well as the small eminence 21 of the foot and the area of the big toe which is not shown, are located; · * Clearly on the horizontal plane 9 of the sole.

: In this case, the big toe and the great eminence 7 of the foot are clearly located lower than the small eminence î · 21. A tangent 20 applied against the surface 5 of lasarnDe: '755 in this zone is sloping in pronation relative to the horizontal plane 9 of the sole. This is true for practically the entire surface area of the forefoot sole. The resulting pronation angle 20a with respect to the horizontal plane 9 is between about 2 ° and about 10 ° 8 and preferably reaches about 5 °.

In the transition zone between the forefoot. and the metatarsus is provided, in the shoe, a metatarsal support which is noted in the surface of the sole 5 of form 1, by a pronounced depression 14.

The sectional plane, according to FIG. 4, passes through the point 22 of maximum depth of the recess 14 in the area of the sole 5. It can be seen in FIG. 4 that the lowest point 22 of the recess 14 is located above the horizontal plane 10 * of the sole reproduced by the straight and horizontal line between points 10c and 10d of the "edges of the sole in FIG. 4. The level of the lowest point 22 above the plane horizontal of the sole reaches approximately 1 to 2 mm.

15 Of course, the invention is in no way limited to the embodiment described and shown, which has been given only by way of example, bn in particular, it includes all the means constituting technical equivalents of the means described, as well as their combinations, if these are executed according to his spirit and implemented in the
