Description

Functional shoe soles

This patent relates to a sole attached to an insole of a shoe, specifically, the sole of the shoe is based on the center surface formed by extending vertically to the ground at a predetermined position of the sole where the metatarsal head of the foot is located, the front sole of the toe side By realizing a functional shoe outsole, which is separated by a separating surface into a rear sole on the side of the heel and attached to the insole, the sole of the shoe is variable according to the bending of the foot and the change of the shape of the foot during walking as described above. The present invention relates to an outsole attached to an insole of a shoe to enable manufacturing of a shoe that is easy to walk.

In general, a person's foot repeats bending and twisting around a connection node of a scapula and a metatarsal bone while walking to form a bevel angle. Most conventional shoe soles are integrally formed so that they do not effectively cope with changes in the shape of the foot generated when walking. I can not feel much inconvenience in walking. Conventional known techniques for solving this are as follows.

First of all, Korean Utility Model No. 1992-0000449 is a shoe sole technology, which consists of the first layer, the thick second layer, the third layer and the fourth layer in contact with the ground and is connected to the upper to form the shoe sole. In the present invention, the shoe sole has a cushioning effect by presenting a shoe sole formed by forming a plurality of upward protrusions having a height higher than the thickness of the third layer and extending to the fourth layer through an opening formed in the third layer. Efforts have been made to improve flexibility by forming a requirement (groove) with a massage effect. However, the present technology provides the effect of increasing the cushioning effect and the massage effect through protrusions provided on each layer of the sole. Therefore, the effect on the flexibility (variability) of the sole of the shoe according to the shape of the foot when walking is insufficient.

In addition, the Korean Utility Model Registration No. 20-0374035 proposes a shoe sole in which the soft sole is coupled between the rigid sole in the agglutination zone of the shoe which is curved according to the joint movement of the foot during walking. The joint surface is formed in the warp direction corresponding to the shear force applied when walking on the joint of the soft sole and the rigid sole, and the joint surface is joined to each other, and the joint surface is extended to the joint area of the soft sole and the rigid sole. It characterized in that the expansion surface, between the joint surface further extends the coupling expansion surface and the engaging jaw portion is formed to engage with each other as a reinforcement structure for the tensile force to propose a bonded shoe sole.

This known technology has the advantage of pursuing ease of walking by configuring the shoe sole to have a variable according to the shape of the foot when walking, but since the joint portion of the rigid sole and soft sole is a lot of bending part of the hard sole and soft sole There is a problem that the joints can easily be damaged, and due to the soft tension of the soft sole, it is difficult to effectively cope with the large bending (shape change) of the foot caused by walking due to the soft sole configuration.

As described above, the shoe sole according to the prior art is composed of an integral or grooved sole, which does not preferably reflect the change in the foot shape caused by walking, and thus is difficult to walk. Required.

This patent is designed to improve the problems associated with the technology related to the outsole attached to the insole of the conventional shoes, the foot of the person repeats the bending angle and repeating the bending angle and 으로 around the connection node of the femur and metatarsal bone when walking Since the shoe sole according to the prior art is formed in one piece or a sole provided with a groove, it does not preferably reflect the change in the shape of the foot that occurs when walking, and thus the patent is difficult to walk. It aims to provide a solution.

This patent is intended to realize the intended purpose as described above,

The sole of the shoe is attached to the insole by separating it into a front sole on the toe and a rear sole on the heel based on a center plane formed by extending vertically to the ground at a certain position of the sole where the metatarsal head of the foot is located. By providing a functional shoe sole characterized in that the present suggests a functional shoe outsole that can be changed according to the shape of the foot and the bending of the foot when walking as described above.

The shoe sole according to the present invention realizes a shoe sole that facilitates bending and stiffening around the connection node between the stunned bone and the metatarsal bone as the above means, so that the shoe sole according to the prior art is formed in one piece, There is an effect to solve the problem that the change is not easily reflected walking is not easy.

The present patent relates to a shoe sole attached to the shoe insole 50 to facilitate walking by forming a shoe sole that can be changed in shape according to the change in the bending form of the foot when walking, the sole of the foot is the foot metatarsal head 71 Based on the center surface 30 formed by extending vertically to the ground at a predetermined position 80 of the sole where the) is located, the separated surface into a front sole 10 on the toe side and a rear sole 20 on the heel side ( 40) relates to a functional shoe sole characterized in that it is separated and attached to the insole 50.

Hereinafter, the present patent will be described in detail with reference to the accompanying drawings 1 to 10 showing an embodiment to which the present patent is applied.

First, as shown in FIG. 3, the foot of a person lying on the flat ground has a small angle between the proximal phalanx corresponding to the toe part (proximal phalanx, 60) and the metatarsal bone 70 corresponding to the instep of the foot, and the proximal bone (60). And the sole surface where the metatarsal bone 70 is located all form a contact surface parallel to the ground, but the shape of the brace in the step of walking the foot when walking is as shown in Fig. The sole of the foot is a force parallel to the ground, and the sole of the foot where the metatarsal bone 70 and the metatarsal bone 70 are located is the metatarsal head 71 (haeta, body, limbs). (hae) is a part adjacent to the joint connected with the basal bone (60). Because it is inclined to form a large angle with the ground, the groove is formed integrally or in part. Conventional shoe sole consisting of has a dullness when walking There was a difficult problem of walking.

Thus, the present patent is the sole of the foot attached to the insole 50 of the shoe as shown in Fig. 1 sole foot foot (71) (in this patent, the connection node between the basal bone and metatarsal bone is called 'foot metatarsal head') Based on the center surface 30 formed by extending vertically to the ground at a predetermined position (80) of, separated by the separating surface 40 into the front sole 10 and the rear sole 20 of the heel side By the construction, the sole of the shoe is easy to walk.

In other words, the macroscopic configuration of the shoe sole according to the present patent is a two-part centering around the metatarsal head 71 which becomes the center of bending when the foot is set to be variable according to the change in the bending form of the foot when walking the shoe sole composed of an integral By separating and configuring the foot to bend and stretch when walking, the macroscopic configuration is as follows.

The shape and size of the foot varies depending on the individual, but the shape of the brace in the step of walking when walking is the sole of the foot on which the stunned bone (60) corresponding to the toe part is placed in parallel with the ground and exerts force on the ground. , Sole foot in which the metatarsal bone 70 is located is inclined to form a large angle of inclination with the ground around the metatarsal head 71. At this time, the present patent is based on the center surface 30 formed by extending vertically to the ground at a certain position 80 of the shoe sole corresponding to the position of the metatarsal head 70 of the metatarsal bone 70, which is the center of the angle of the toe, the toe side When the foot is stepped for walking by separating the front sole 10 and the rear sole 20 of the heel side as the separating surface 40 and attaching to the insole 50 of the shoe, respectively, in a form parallel to the ground Anterior outsole 10 on the side of the toe located (shoe sole where the bone 60 corresponding to the toe part is located) and the rear outsole on the heel side forming a certain angle of inclination with the ground ( 20) (the sole portion of the shoe where the metatarsal bone 70 is located) is easily bent, so the sole is made of a hard material, the sole is thin, and the sole is not easily bent, such as thick work safety shoes or tall shoes.The effect can be obtained that is easy walking shoes.

In addition, the present patent has a separate foot surface for separating the front sole 10 and the rear sole 20 of the shoe sole for better walking ease of the shoe sole having the above configuration, the foot metatarsal head 71 of the foot 5 to 45 ° in the rear sole 20 direction with respect to the center surface 30 formed by extending vertically to the ground at a predetermined position 80 of the outsole, the center of which is located 80 It is configurable to be inclined to have the separation surface forming angle (95). This is because the sole has a predetermined thickness as shown in Figure 6 centered on a certain position 80 of the sole where the metatarsal head 71 of the foot is located, and the center surface 30 formed by extending vertically to the ground at a predetermined position 80 of the sole Since the portion adjacent to the ground of the separation surface 40 of the rear sole 20 which is inclined with the separation surface forming angle 95 relative to the ground occurs, the separation surface 40 is separated. By configuring to be inclined as the center and reference as described above, it is possible to minimize the interference between the portion of the separation surface 40 of the rear sole 20 and the surface adjacent to the ground. In addition, the separation surface formation angle 95 can be configured according to the judgment of those skilled in the art according to the thickness of the shoe sole, but less than 5 ° even if the thin shoe sole is less effective and exceeds 45 ° too large separation surface formation angle (95) Due to the problem that it is difficult to walk due to the difficulty of effectively transmitting the propulsive force of the foot to the ground when walking, it is preferable to have a separation surface forming angle 95 in the range of 5 ~ 45 °, the rear sole 20 for the configuration By using the insole of the shoe in conjunction with the front sole 10, there is an effect that can realize a shoe sole easier walking.

In addition, the patent separates the anterior sole 10 and the rear sole 20 in consideration of the stericity of the femur in separating the shoe sole into the anterior sole 10 and the rear sole 20 as described above. 7 to 8 is formed to form a position toward the heel by a length 90 in the range of 2 ~ 5cm than a predetermined position 80 of the sole where the metatarsal head 71 of the foot is located as shown in Figure 7 to 8 It is preferable. This strictly analyzes the bending of the brace when walking, but the theoretical bending of the brace when walking is formed around the metatarsal head 71, but since the metatarsal bone 70 is formed in a three-dimensional form having a predetermined volume as shown in FIG. 4. When walking, part of the metatarsal bone 70 including the metatarsal head 71 along with the sole of the foot where the basal bone 60 is located is applied to the ground in a form parallel to the ground so that the sole of the shoe is the front sole 10. Separation surface 40 separating the rear sole 20 and the foot 90 in the range of 2-5 cm than the predetermined position 80 of the shoe sole where the metatarsal head 71 of the foot is located (preferably the metatarsal bone 70 Thickness of the foot—generally, the thickness of the metatarsal bone 70 of the human foot has a thickness within the above range. Thus, the shoe sole may be more easily walked.

In addition, the present patent has a rear surface of the separation surface 40 formed on the basis of the center surface 30 formed by extending vertically to the ground at a certain position 80 of the sole where the metatarsal head 71 of the foot is located as shown in FIG. 20 are configurable in number. Preferably, based on the separation surface 40 formed on the basis of the center surface 30 formed by extending vertically to the ground at a certain position 80 of the sole where the metatarsal head 71 of the foot is located in the rear sole 20 By constructing one or two separate surfaces within the range of 2 to 5 cm in the heel direction, the angle of inclination of the rear sole 20 is more flexible, and the position at which the separate surface 40 separating the sole is formed as described above. Foot easier to walk in consideration of the thickness of the foot bone 70 of the foot by forming a length 90 toward the heel than the predetermined position 80 of the sole where the metatarsal head 71 of the foot is located.
