Description

[Detailed description of the invention] Hikari name General purpose shoe technique with deformable subtalar section Younno FIELD OF THE INVENTION The present invention relates generally to the technical field of footwear, and more particularly to foot, heel, and relating to the technical field of footwear covering at least a part of the division.

More specifically, the invention can be used as a sports shoe or even as a simple walking shoe. , as well as general-purpose shoes that can be used as rehabilitation shoes. However, it is not limited to this.

The above-mentioned applications are - by way of example only and may vary depending on the type of movement and type of movement involved. capable of supporting the human foot and joints, regardless of the type of activity. shall be considered as limiting the field of application for the purposes of the present invention, which applies to any shoe that Must not be.

Regardless of the field of use considered, shoes have various functions and characteristics. Provides mechanical protection, insulation, comfort in use and maintenance or support of the foot and heel joints. Must-have. Depending on the specific use for which the shoe is intended, the nature of the materials used may vary. You can adjust the quality and properties or provide specific reinforcement zones and thickness. or even change the shape of the shoe itself to create a singular or plural functions will be given priority over other functions.

Until now, the need to protect and support the division and the joints of the foot, on the other hand, and at the same time During the need to avoid excessively restricting and even disrupting the joints of the legs and divisions The contradictions that exist have not been completely resolved.

The technical constraints involved are such that in fact all attempts to stiffen shoe coverings are In principle, it improves joint support at the expense of user comfort. This is contradictory. Conversely, improving the user's sense of comfort is due to the flexibility of the shoe covering structure. This can be achieved through an increase in joint function, or alternatively at the expense of the supporting function of the joint. just , in both cases, the natural conditions of movement of the joints of the foot and joints are significantly different from the optimal conditions. We will be far apart.

Therefore, joints are highly dynamically stressed due to lack of or excessive fixation. This is the cause of very frequent twisting accidents of the foot and joints in sports activities. This is the cause of the vines.

Conventional technology The first type of sports shoes currently known is based on foot movement and heel movement. consists of shoes that cover the In other words, this shoe shortens the flexibility of a part of the calcaneus-miscellaneous block. It is merely a fixation. The use of such shoes is for tennis, football, track and field It has been generalized to many sporting activities of the type competitive or jogging. , the improvement is basically the issue of dynamic shock buffering, plantar arch support, and even adhesion. This is related to the issue of.

Due to its very design, this type of shoe does not allow for immobilization of the foot joints, let alone the heel. This is not the purpose of this research, and no particular research has been conducted in this field. Ta.

The second type of sports shoes is sports shoes called short boots. It consists of In other words, this type of sportswear is a foot shell. In addition, it also includes an upper that fixes the entire joint of the foot and section, that is, a flexible covering. I'm reading.

Shoes made according to this traditional principle are suitable for basketball, football, and tennis. Flexible support and fixation are used in most sports such as Because of this, such shoes are prone to twisting when performing sports activities. In case, the section joints are not effectively protected. Due to the flexibility of the fixation, In reality, the section joints are not well supported in case of unexpected torsion, and therefore This can lead to sprains of the subtalar ligament and, in some cases, the tibia and tarsal ligaments. Ru.

In the case of walking shoes, especially climbing shoes, the fixation of the joints of the section is ensured in an almost rigid form. It can be assumed that twisting accidents, such as sprains, can be avoided in the vast majority of cases. Even if the ligament is damaged, the feeling of comfort during use will be reduced, and the ligament damage You have to think that it will happen suddenly at the knee level, not at the bell.

Details of main story SUMMARY OF THE INVENTION It is therefore an object of the present invention to avoid the disadvantages of conventional shoes and to provide foot and ankle joints with a self-supporting shoe. Allows the foot and heel to move freely without sacrificing comfort while respecting natural physiological movements. Our objective is to propose general-purpose shoes that can support natural joints.

Another object of the invention is that it is simple in design and can be applied in a variety of ways, yet can Our goal is to propose general-purpose shoes that can be used in sports.

Another object of the present invention is to simultaneously protect the talocaneal joint and the tibia-tarsal joint. Our goal is to propose general-purpose shoes that can be used for various purposes.

The object of the present invention is to provide a support for supporting all or part of the calcaneus/miscellaneous block. e.g. sports shoes 1 walking shoes or is a rehabilitation shoe type general-purpose shoe that is suitable for valgus and varus movements. The foot at the level of the talocalcaleal joint to fit the small (and partially) A relatively movable calcaneal shell and heel shaft through a deformable subtalar section that covers This is achieved by a general-purpose shoe characterized by including a retaining upper.

Various other features may be included in the scope of the invention by way of example and without a limiting meaning. It will be made clear by the description given below with reference to the accompanying drawings illustrating embodiments of the It becomes something.

FIG. 6 shows a side view of another variant embodiment of the object of the invention.

FIG. 7 is a top view of a shoe according to the invention.

medical treatment Figure 1 shows that the outer covering 2 as well as the sole 3 are included in one shoe, which is indicated by dashed lines. The arrangement of bones constituting the talocaneal joint of human section 1 is schematically shown. shown here The overall view is almost perpendicular to the shoe support and extension plane embodied by plane P. , and the right side of the person as seen from the outside according to a plane extending in the direction of the main longitudinal axis of the shoe. The position of the heel 1 on the instep can be considered as an example. This plane P is the shoe It can be considered as the support and extension plane of the base 3.

The talocaneal joint of the heel is the calcaneus4. Talus 5 and cuboid 6. Scaphoid 7, then part shown in Figure 1 an assembly consisting of a series of bones including the cuneiform, metatarsal, and phalanx It consists of a block called the calcaneus/miscellaneous block, which includes the li.

The talus 5 is connected to the calcaneus 4 via two ligaments 8 and 9 that intersect with each other. Ru. The movement of the talocaneal joint in space is determined by the movement of the calcaneus and miscellaneous block in relation to the talus 5. It can be thought of as a result of relative position within the overall space of positions. even more strict In detail, these movements are performed in an anatomically conventional manner to accommodate heel varus and valgus movements. It is made up of movements called motions.

The varus of the section combines the following combinations of movements in three planes of space: It is a sudden movement: According to Figure 1, in a horizontal plane that is one with plane P, towards the inner surface of the opposite foot. This rotation is called adduction; this type of adduction rotates the longitudinal axis of the foot a maximum of about 30 degrees in relation to the normal vertical position, where the plane is approximately parallel to the human symmetry plane. exhibits amplitude.

The so-called internal roll at the front surface corresponds to a plane perpendicular to the plane P. Its amplitude is , and the relationship between the two extreme positions called the upper and lower limits of the magnitude of the rolling motion. It is defined as approximately 25 degrees in the angle.

This is called plantar flexion in the sagittal plane, which is not shown and is embodied in the plane of the cross-sectional view in Figure 1. Bend exposed. Its amplitude is related to the human's normal vertical position with respect to the horizontal plane. is defined as 10 degrees oriented along arrow f.

As a reference, the amplitudes listed above correspond to average values derived from practice, each Of course, the amplitude of For example, it may vary by about 5 to 10 degrees.

Similarly, valgus refers to the human valgus in three planes and directions of space. It is a movement that connects the entire movement of the section away from the vertical plane of symmetry. these The valgus movement is the most extreme movement in the knee horizontal plane that can be realized by: Great 30 degrees of abduction.

- External roll of approximately 20 degrees at front F.

- dorsal in the sagittal plane oriented along arrow f2 in figure 1 with an amplitude of approximately 10 degrees; A bend called a plane bend.

The research conducted by the applicant on the movement and displacement of the talocaneal joint of the foot and section is as described above. The entirety of these varus and valgus movements according to the spatial plane and direction of the instantaneous displacement axis Furthermore, a geometrical shape that can be identified with the rotating cone 11, hereinafter referred to as the subtalar cone, is also included. It has an instantaneous axis of movement such that displacement is circumscribed and limited to a covering of geometric shape. It showed that there is.

The apex S of the cone 11 is approximately one third of the height H representing the height of the rear edge of the calcaneus 4. Consider that it is at a distance d of approximately several centimeters behind the calcaneus 4 at approximately the same height H8. be able to. The apex S is likewise located approximately at the center of the geometrical projection of the calcaneus 4 on the anterior surface E. To position. The cone 11 likewise has a constant inclination in relation to the plane P; is formed by ligaments 8 and 9 that intersect at the central axis 12 of the cone 11. The vine is defined through two beams that are connected to each other. Actually, the intersection between the reference plane P and the central axis 12 is The angle α formed by the difference has a value between 20 degrees and 50 degrees, more generally It can be seen that the value preferably ranges from 30 degrees to 45 degrees.

The cone 11 is further defined by its opening angle β (Fig. 2), and the average of this angle Values vary from 15 degrees to 30 degrees depending on the age of the individual and his anatomical characteristics . Figure 2 shows the top of the right foot placed inside a shoe 2 whose shape is projected onto a horizontal plane such as a plane P. It shows a top view. Here, the main longitudinal axis x-x' of the shoe 2 is the center of the cone 11. Together with the axis 12, it forms an angle g of approximately 10 degrees to 30 degrees. Therefore, to people Therefore, the subtalar cone 11 indicates the person's axis of symmetry, that is, the direction toward the inside of the foot. present.

Therefore, the entire geometric and angular definition of the subtalar cone 11 provides a Defining the placement and directionality in space of the cone within which the instantaneous axis of motion of the node moves. becomes possible. (Thus, the subtalar cone 11 has an anatomical and physiological basis. Based on this, a geometric and mechanical model representing the joint motion of the section is constructed.

to 50 degrees, preferably from 30 degrees to 45 degrees. , if the subtalar section 21 covers the front part of the foot, the subtalar section 21 covers the front part of the foot. This includes the opening angle β of the horn 11.

In order for the subtalar section 21 to ensure flexible fixation of the talocalcaneal joint, , a material in which this joint is deformable and which constitutes the intermediate upper 22 and the calcaneus shell 17. The intermediate upper 22 and this shell 17 are relatively movable. It is necessary to become in a state. For this reason, the intermediate upper 22 and the calcaneus shell 17 are a rigid material, or at least a carbon-based or carbon-Kev exhibiting a degree of rigidity; Composite material bases of the LAR (Kevlar) type and even types of high-density plastics It can be manufactured from block material-based materials. The subtalar section is an application type Variants of polymeric or synthetic fiber types that can change their elasticity depending on It can be made from any possible material.

FIG. 5 shows details of the implementation and assembly of the subtalar section 22 in the form of a cross-sectional view. There is. The subtalar section 22, in the illustrated example, is connected to the subtalar cone 11. Correspondingly, it has the deformation ability to adapt to the valgus and varus movements of the heel joint, and the talocaneal joint. Consisting of 11 approximately circular concentric pleats 26 forming an enveloping accordion structure. It consists of a subtalar bellows 25. Here, the subtalar cone 11 is at least Inside the orthosis partially constituted by bellows 25, parallel to the extension plane P of the sole According to the plane, the talocalcaleal joint of the section is projected geometrically along the dashed line in Figure 5. Note that the bellows are arranged so as to envelop the Bellows 25 is an example by any suitable means known to those skilled in the art, including machine sewing or gluing. and is integrated with the intermediate upper 22 and the calcaneus shell 17, as shown in FIG. It is placed on the outside and even inside of the sea urchin shoe. Flexible protective loop on bellows 25 It is also possible to add and fix it. Advantageously, the cone 11 is a subtalar bellows. 25, this bellows has a cover with a wider front part than the rear part. Constitutes a cover.

For example, during forced joint movement in valgus, the rigid calcaneal shell 17 Due to the deformation of the talar bellows 25, it can abut against the intermediate upper 22, and this At this time, the upper surface 17a of the calcaneus shell is pressed against the lower surface 22a of the intermediate upper 22. It will be.

Naturally, instead of the subtalar bellows 25, other machines with radial deformation and It is also possible to use mechanical means, in which case the deformability and stiffness of the calcaneal shell 17 and the intermediate upper 22 are provided with relative mobility.

- As for the deformity, the above-mentioned supratalar bellows 25 is the type of subtalar bellows. Instead of a calcaneal shell 17, a calcaneal shell 17 is connected directly between the intermediate upper 22 and the calcaneal shell 17. It is also possible to use a subbony section 21. For this purpose, for example, carbon-K Subtalar section 21. with the same composite material such as evler type. Calcaneal shell 1 7 and intermediate upper 22, at this time the subtalar section It is necessary to gradually change the composition of the material at the level of the coating representing the write By increasing the Kevlar density relative to the carbon density, the subtalar The stiffness of the section 21 is reduced and a change equal to that obtained by the supratal bellows 25 It becomes possible to give it shape ability.

Performing deformations of the subtalar section depending on the intended use of the shoe, in particular the required dynamic lateral forces One of the aspects is selected.

FIG. 4 shows a deformable tibia-tarsal bone section attached to the intermediate upper 22. According to the invention, the variant shown in FIG. 2 represents a second variant embodiment of the shoe; The tibia/tarsal bone section 31 is Intermediate upper at tibial-fibula clip 33 level using uniaxial hinge fastening device 34 22 in combination with an upwardly facing leg upper 32 hinged on top 22.

The tibia/fibula clip 33 has a rotation axis inclined from the human symmetry plane toward the horizontal plane P. The single-axis hinge device 34 has a rotation axis that is integrated with this tilted axis. are doing. The lower leg upper 33 may be rigid, or alternatively only partially rigid. The rigid part may have a flexible part at its upper part, and this rigid part is connected to the hinge clasp. limited to the vicinity of the device 34.

At least one tibial-tarsal section 31 for surrounding the upper part of the section. Preferably it is complemented by two deformable bellows. Preferably tarsal deformity Possible bellows are called front bellows 35 and rear bellows 36, each with a specific opening angle. It consists of bellows.

The anterior bellows 35 and the posterior bellows 36 are used to realize the subtalar section 25. It can be made of flexible, deformable plastic material similar to - May consist of a series of approximately radial folds giving each bellows a dion structure. stomach. Advantageously, the lower leg upper 33 extends from the front to the back of the shoe, preferably towards the front of the shoe. towards the back of the shoe with an amplitude of about 30 to 90 degrees, preferably about 45 degrees. lateral to the tibia-fibula clip 33 with an amplitude of approximately 30 degrees to 90 degrees, preferably 60 degrees. It can rotate around the directional axis. The angle value determined in this way is Due to the deformation in the angular range, the lower leg upper 33 hits the intermediate upper 22. The respective opening angles of the front bellows 35 and the rear bellows 36 that can be touched It almost matches the degree.

Shoes with a tibial-tarsal section are therefore suitable for immobilization with mobility of the talocaneal joint. In addition, it allows fixation of the joint at the tibial and fibular clip level, which When applied to sports activities, it does not have a negative effect on the user's sense of comfort. Improves foot and leg joint support.

In the two examples above, the opening of the shoe is either a lace-up or a lace-up in the front part of the shoe. or by successive fitting of the various components of the shoe on the subtalar section. This can be done in a conventional manner depending on the situation.

Variants placed on the shoe according to the subtalar cone 11 representing valgus and varus movements of the heel. Achieving a versatile shoe with a shapeable subtalar section improves the physiology of the talocalcaleal joint. Perfect fixation and user comfort due to its respect for anatomy and At the same time, it is possible to obtain such shoes in a simple and effective manner.

In fact, the alignment is such that all of the natural movements of the talocaneal joint are allowed, and the Valgus or varus motion can produce an instantaneous axis of displacement outside the subtalar cone The deformity of the subtalar section is caused by the user's - It's not a hindrance. In this case, these limit values are then The projection of the calcaneal shell 17 against the intermediate upper 22 ensures effective fixation of the heel joint. Corresponds to joint pressure.

Naturally, if fixation must be improved, the calcaneal shell 17 and the medial The abutment of the upper 22 is such that the instantaneous displacement axis of the covering is determined by the subtalar cone. It is possible to intervene before the limit is reached, thus limiting the amplitude of the displacement of the talocaneal joint. It will be limited. Such restrictions are of course designed for use in motor rehabilitation. Advantageous in the case of measured shoes.

The present invention is not limited to the illustrated example described above, but can be modified in various ways. It is possible to Therefore, the rear covering tongue integrated with the intermediate upper 22 41 and a uniaxial hinging device 4 placed near the apex S of the taloglossal cone 11 It is also possible to attach the intermediate upper 22 directly to the calcaneus shell 17 via the calcaneus shell 17. (Figure 6). The axle system advantageously has a main axis 12 of the subtalar cone (11) and It may consist of a pivot with approximately one axis.

It is possible to meet Risato on 1 presentation. The object of the present invention is to be used for realizing sports shoes or rehabilitation shoes. It is particularly advantageous to use
