MXPA06007774A - Diagonally twisted sole - Google Patents

Abstract

The invention relates to a diagonally twisted sole (3) consisting of a lower sole (12) and a median sole bottom (11) connected to the lower sole (12). Various hard inserts (15) can be introduced into the lower sole (12). Together, said lower sole (12) and a twisted, flexible, rigid or elastic plate (16) can form an intermediate sole (12, 16) which can consist of a plurality of parts. The twisted plate (16) is a flat plate or a plate of various thicknesses.

Description

TORCIDA SOLE DIAGONALLY The present invention relates to a sole bent diagonally in accordance with the preamble of claim 1. In Patent No. WO 01/15560 Al cited: "The human being, with its highly complicated apparatus of ligaments-muscles-tendons and The sensitive erect spine is designed to move in the wild on uneven grounds.For several thousand years the human being used and maintained his body in accordance with this natural condition. " In that patent application, the shape and conformation of the midsole and the sole of the shoe are described in detail. Studies were carried out with the inclusions in the sole described. Their knowledge and conclusions lead to the present patent application. The tests and observations show that a natural movement has approximately the following evolution: when stepping on the heel, the foot rests on the outer edge of the heel. Subsequently, the foot rolls at an angle to the inward direction until it hits the tenor oriented against the middle between the two feet and the big toe. The load on the sole of the feet moves along its diagonal. From the heel that receives the load outside, the line of load extends diagonally on the sole of the foot until the tenar and the big toe inwards. The footprint of a healthy human being also shows that the above is correct. In many cases, with the children it is still good that the heel, the outer edge of the foot and all the tenar with fingers are reproduced in a footprint, but not the place under the instep. In the case of elderly people there are other traces that result from poor posture and inadequate movement of the feet. In a civilized population that for generations has been accustomed from childhood to shoes, there is a deformation of the feet in the following characteristic: the big toe is oriented outward from the middle starting from between both feet. On the other hand it is known that in natural populations the big toe is always in the center between both feet. The reason must be that, in this position, the big toe can better support the tenar in the impulse. This torsion of the load on the foot is needed in the population of civilized society, accustomed to shoes and hard and flat floors. When walking on flat floors, the flat sole forces the foot to perform a straight rolling motion. The lateral load is modified and, with time, the rolling movement in the lateral direction is stopped. This incorrect rolling motion must be compensated by the knee and hip joints as well as the spine, and this has the consequence, in turn, that due to incomplete rolling of the feet the load is distributed incorrectly throughout the motor apparatus. As a result of the above, our society suffers from all types of postural damage with painful osteoarthritis and spinal problems. The present invention now proposes the objective of correcting incorrect treading and rolling when walking in the aforementioned manner, so that the natural rolling movement with diagonal loading curve of the soles of the feet is gently forced and gently forced to the walk the movements and the natural and dynamic loads of the joints of the knee and the hip and of the spine. This objective is achieved with a diagonally twisted sole with the features of claim 1.

Other features according to the invention are apparent from the dependent claims and their advantages are illustrated in the following description. In the drawing shows: Figure 1, the configuration of the shoe. Figure 2, the side view in theory of a diagonally twisted sole.

The figures reproduce preferred embodiments, which are illustrated with the following description. In the patent specification WO 01/15560 Al is described (Figure 1) how different loads of the foot can be achieved by hard inclusions 15 in the lower sole 12. In the above, we had already thought about the directed therapeutic measures that could be achieved with this type of sole 3 and shoe 1. Now it has been observed that for the generality it applies what was described in the previous introduction: in people who complain of knee, hip or back pain, the load line of the foot when walking no longer extends diagonally on the foot. It is "groped" so to speak forward and a load line is loaded on the foot that extends in the direction of the advance. Thus, with the rotation, the joints of the knee and the hip receive the load always in the same place. The complete dynamic movement when walking is missing. This results in painful wear and often osteoarthritis. The shoe 1, respectively its sole 3, already allows the desired load line to be adjusted by placing the various inclusions 15 and of different hardness at the bottom of the midsole 11. The bottom sole 12, totally elastic, sand type allows This possibility. That is to say, already with this measure a shape of the diagonal load line and of free definition can be adjusted. It has now been observed that it is advantageous to shape the bottom sole 12 against the bottom of the sole 13 so that it assumes the diagonally twisted shape shown theoretically in FIGS. 1 and 3. In these reproductions, the torsion is very marked in order to illustrate the idea of invention In practice, the torsion indicated by the angle a in the area of the fingers Z and with the angle ß in the area of the heel A, will be of few degrees with respect to the horizontal H. Likewise, the torsion of the bottom of the sole 13 it will always adjust and conform freely to the needs of the patient. In special cases it is conceivable not to twist it systematically, but to adjust it to a malformation, incorrect posture or impediment of a foot. For aesthetic reasons, the shoe will look as normal as possible. The type described above does not allow this, since the shoe rests on a very labile surface and is markedly different from a normal shoe. Figures 12 to 19 show how the same can be achieved if a twisted plate 16 is placed in the soft bottom sole 12 instead of individual hard inclusions. Subsequently, the bottom of the sole 13 will be parallel to the horizontal H, as shown in Figures 13 to 18. This twisted plate 16 is hard and, either, completely rigid or elastically flexible, and joins the bottom of the midsole 11. The gap between the bottom of the midsole 11 and the bottom of the sole 13 is filled in together by the twisted plate 16 and the lower elastic sole 12 of the sand type. The twisted plate 16 and the lower sole 12 together form an elastic midsole 12, 16. The twisted plate can be shaped in different ways. If the planes of the bottom of the midsole 11 and the bottom of the sole 13 are parallel in the direction transverse to the direction of advancement, the bent plate has on its surface different thicknesses, as shown in Figures 13, 15, 16 and 18. Then, the elastic midsole 12, 16 is harder in the places of greater thickness of the twisted plate 16 (for example, Figure 16 to the right), and softer in the thin places thereof (for example , Figure 16 on the left). The flat twisted plate 16, as shown in Figures 2 and 3, joins the bottom of the sole 13, which is shown, for example, in Figures 5, 6, 7, 8, 9 and 10, or is joined with the bottom of the midsole 11, this then assuming the shape of the twisted plate. With the present invention it is possible to help patients with postural damage of different types, by providing them with shoes adjusted in this way, according to their condition, for daily use. In the above, the great advantage is that patients do not have to follow exercises or a predetermined gymnastics, but follow their therapy with daily use.
