Description

Hybrid Insole with multi-shock absorbing pad and Method for fabricating thereof

This patent relates to a functional insole, and more specifically, a hybrid equipped with a multi-impact absorbing pad that distributes and absorbs the weight of the human body by arranging an absorbent pad corresponding to the bone structure for each part of the human foot. It relates to an insole and a manufacturing method thereof.

In general, an insole is provided inside shoes, sports shoes, etc., not the sole of the shoe, and it can function to absorb shock transmitted from the ground and gently handle terrain changes while in direct contact with the entire sole of the foot.

If the sole is an element constituting the shoe and is non-replaceable and is fixed to the lower part of the upper, the insole or insole is an element that is replaceably located inside the upper and can add a cushioning function to the shoe, and can be in direct contact with the sole. It is different in that it can perform various functions such as balance control in addition to shock absorption.

When walking or jogging, a weight load of 1.2 to 8 times of body weight is continuously applied to the waist, knees, and ankles. The cartilage between each joint and the arch of the sole act as a buffer to absorb this weight and prevent damage to the joint and bone.

The cartilage and arch of the sole absorb and disperse the shock transmitted to the human body when the foot lands on the ground, and immediately form a repulsive elastic state when the foot falls from the ground. In this way, the cartilage and arch of the sole repeat the action of absorbing or distributing the shock applied to the human body innumerable during daily life.

Therefore, cartilage and arch of the sole, which play a more important role than any other organ in the human body, require continuous management so that they can be used well for a long time. The protection of the cartilage and the arch of the sole is largely dependent on how well the foot that receives the weight of the human body directly distributes and absorbs the shock caused by the weight load.

The foot is made up of 26 large and small bones, which are supported by ligaments and muscles. In addition, the bones constituting the foot form several domed arch structures to properly distribute and absorb the weight of the human body.

However, humans living in the modern world are continuously impacting their feet due to weight gain due to obesity, living on hard concrete floors or asphalt, and incorrect posture. Due to this, the dome-shaped arches of the foot that support the weight load and distribute the weight load are deformed over time. Deformation of the dome-shaped arches causes the human body to lose the balance of articular cartilage, preventing the foot from absorbing or distributing weight properly.

As such, when the foot cannot properly support the weight of the human body, not only a direct disease of the foot such as plantar fasciitis occurs, but also fatigue is continuously accumulated in the cartilage of the knee joint, thereby causing knee arthritis due to cartilage wear.

In particular, in Patent Registration No. 10-0675816, an invention of attaching an air band with a built-in air bag that can be corrected through tightening the height of the arch at the point where the inner and outer arches of the foot are connected has been proposed, but the protective effect on the entire sole is not. Couldn't expect much.

In addition, the above invention does not take into account that the weight load applied to each part of the foot that comes into contact with the ground is different over time when a human is walking or jogging, so the fundamental solution to the deformation of the dome arch of the foot is not There is an impossible problem.

Each of the plurality of sheet layers constituting the insole body 110 may be made of a stretchable material having absorbency, thermal barrier properties, lightness, anti-inflammatory, antiviral, antimicrobial, and antibacterial properties.

For example, it may be formed of a sheet layer of kenaf or a mixture of kenaf and rubber. In addition, any one of a resin-based material such as nylon (nylon), PP (polypropylene: polypropylene), PE (polyethylene: polyethylene), EVA (ethylene-vinyl acetate) at least one of the layers constituting the insole body 110 can be formed into one.

When the seat layer constituting the insole body 110 is made of a resin-based material, strength, durability, adhesion, and cushioning for supporting the weight load required for the insole in the process of manufacturing the seat layer can be imparted.

The first and second absorbent pad means 180 and 190 disposed in the hybrid insole 100 of the present invention may be disposed on the upper surface or the rear surface, that is, on one surface of the sheet layer, when the insole body 110 is a single sheet layer. .

In addition, when the insole body 110 of the hybrid insole 100 of the present invention is formed of a plurality of sheet layers, the first and second absorbent pad means 180 and 190 are disposed between the sheet layers or a plurality of sheet layers. It may be disposed on the top surface of the uppermost sheet layer of

Therefore, in the specification of the present invention, for convenience of explanation, the insole body 110 will be mainly described with a single sheet layer, and a case composed of a plurality of sheet layers will be described as an auxiliary. In addition, it will not be distinguished whether the region in which the first and second absorbent pad means 180 and 190 are disposed is the upper surface or the lower surface of the insole body 110 .

As described above, the first and second absorbent pad means 180 and 190 disposed in the hybrid insole 100 of the present invention may be disposed on the upper surface or the lower surface of a single sheet layer constituting the insole body 110 . .

In addition, when the first and second absorbent pad means 180 and 190 are disposed between the sheet layers when disposed (attached) to the insole body 110, the first and second absorbent pad means 180 and 190 ) may be covered by the sheet layer disposed on the upper side, but in some cases, the upper sheet layer may be compressed while the area corresponding to the suction pad means is opened.

First, the structure of the foot of the human body will be described as follows.

The human foot is largely divided into tarsal bones, metatarsals group, and phalanges.

More specifically, the tarsal bone includes the calcaneus region (F5), the talus, the cuneiform, the navicula, and the cuboid region (F4), and the metatarsal bone is the medial metatarsal bone. region (Medial Metatarsal, F2) and lateral metatarsal region (F3).

Here, each area is divided for convenience of description of the specification.

For example, in the tarsal bone, not only the calcaneus region (F5), but also the navicula located in the anterior part of the anterior talus, the cuboid located on the lateral side of the foot, and three cuneiform bones located in the arch form in front of the nasolabial bone. (Cuneiform) can be distinguished.

Accordingly, in the drawings, the medial metatarsal region F2 and the lateral metatarsal region F3 are divided, but some may be included in the calcaneal region F5.

In addition, in the specification of the present invention, as shown in Figure 2, the phalanx (toe bone) region (F1) direction is the anterior direction (F) with respect to the sole of the human body, and the calcaneal region (F5) direction is the posterior direction ( R), and the inner direction is defined as the medial direction (M) and the outer direction as the outer direction (L) based on the metatarsals of the sole of the foot.

The first absorbent pad means 180 disposed on the hybrid insole 100 of the present invention may be disposed on the insole body 110 corresponding to the metatarsal regions F2 and F3 and the calcaneal regions F5 of the human foot. .

In addition, the second absorbent pad means 190 may be disposed on the insole body 110 corresponding to between the metatarsal regions F2 and F3 and the phalanx region (toe bone. F1) of the human foot.

In addition, the first absorbent pad means 180 includes a first absorbent pad portion 180a disposed at a position corresponding to the metatarsal regions F2 and F3 of the human foot 300; second and third absorbent pad portions 180b and 180c disposed at positions corresponding to between the metatarsal regions F2 and F3 and the calcaneal region F5 of the human foot 300; a fourth absorption pad portion 180d disposed at a position corresponding to the calcaneal region F5 of the human foot 300; and first to third connecting portions 181a, 181b, and 181c selectively connecting the first to fourth absorption pad portions 180a, 180b, 180c, and 180d to each other.

Here, the second absorption pad portion 180b corresponds to the medial metatarsal region F2 and the third absorbent pad portion 180c corresponds to the lateral metatarsal region F3. As mentioned above, each region does not strictly correspond to the parts indicating each component of the human foot 300 .

Accordingly, the second absorbent pad portion 180b may overlap a portion of the talus region F4 of the tarsal bone, the navicular bone, the cuboid bone, and the cuneiform bone. In addition, the third absorbent pad unit 180c may also partially overlap the metatarsal region F2, the cubic bone of the tarsal bone, the calcaneal region F5, and the like.

The first to third connecting portions 181a, 181b, and 181c may selectively connect absorbent pad portions constituting the first absorbent pad means 180a, respectively. More specifically, the first connection part 181a connects the first absorption pad part 180a and the second absorption pad part 180b, and the second connection part 181b connects the third absorption pad part 180c and the fourth absorption pad part 180c. The pad part 180d is connected, and the third connection part 181c may connect the second absorption pad part 180b and the fourth absorption pad part 180d. Although not shown in the drawings, in some cases, a connection part connecting the first absorbent pad part 180a and the third absorbent pad part 180c may be additionally disposed.

The first to fourth absorption pad portions 180a, 180b, 180c, and 180d and the first to third connection portions 181a, 181b, and 181c are each formed to have a space therein. In addition, liquid gel (LG: Liquid Gel) having fluidity may be filled in these internal spaces. In particular, in order to secure the fluidity of the liquid gel, the internal space of the absorbent pad may be filled with the liquid gel to have a certain space. As the liquid gel, a silicone-based gel with excellent elasticity can be used. The viscosity of the liquid gel used may be variously selected according to the degree to which a weight load is applied to the human foot.

As described above, the first to fourth absorption pad portions 180a, 180b, 180c, and 180d and the first to third connection portions 181a, 181b, and 181c disposed on the hybrid insole 100 of the present invention provide a space therein. Since it is formed to have, it can be in the form of an absorption tube (Tube Type). 15 and 16 in this regard, the absorption tube may be formed of carbon fiber or synthetic resin. In some cases, it may be formed of a silicon-based material.

In addition, since the second absorbent pad means 190 is also formed in a structure similar to that of the first to fourth absorbent pad parts 180a, 180b, 180c, and 180d, it may be referred to as a fifth absorbent pad part. The absorption tube constituting the second absorption pad means 190 referred to as the fifth absorption pad part may also be formed of carbon fiber or synthetic resin. That is, the materials and structures described with reference to FIGS. 15 to 17 below may be equally applied to FIGS. 1 to 14 .

Also, the first to third connecting portions 181a, 181b, and 181c may have a tube structure in which both sides are open, unlike the first to fifth absorption pad portions 180a, 180b, 180c, 180d, and 190 . However, the first to fifth absorption pad portions 180a, 180b, 180c, 180d, and 190 may be formed of the same material as the material of the absorption tubes respectively disposed on the portion.

In addition, the first to third connecting portions 181a, 181b, and 181c may include injection holes for injecting liquid gel. Here, the liquid gel (LG) is a liquid gel in which the first buffer particles (BP1, BP2) described in FIGS. 15 and 16 are not mixed, but as shown in FIGS. 15 and 16, the first and second buffer particles ( By mixing BP1 and BP2), it is possible to improve the dispersive power and absorption power of the human body weight.

The second absorbent pad means 190 composed of the fifth absorbent pad part is to be disposed on the insole body 110 corresponding to between the metatarsal regions F2 and F3 and the phalanx regions F1 of the human foot 300 . can Unlike the first absorbent pad means 180 , the second absorbent pad means 190 may be formed in a pad shape without an internal space. The absorption tube of the second absorption pad means 190 may be formed of a silicon-based material.

As shown in FIG. 2 , when the insole body 110 constituting the hybrid insole 100 of the present invention is composed of a plurality of sheet layers, the first and second absorption pad means 180 and 190 are connected to the insole body. (110) should be attached. In particular, if the first and second absorbent pad means 180 and 190 are not firmly attached to the insole body 110 , the first and second absorbent pad means 180 and 190 are separated and separated from the insole body 110 . problem arises.

Accordingly, the region of the insole body 110 in which the first and second absorbent pad means 180 and 190 are located should be attached with a stronger compression force than other regions. The first compression region X shown in FIG. 2 is a region having a stronger compression force than other regions (the second compression region Y).

That is, in the insole body 110 , the first compression region X is formed along the periphery of the region where the first and second absorbent pad means 180 and 190 are disposed.

In addition, the first and second absorbent pad means 180 and 190 disposed in the hybrid insole 100 of the present invention serve to absorb and distribute the weight of the human body, so that the sole surface of the human foot 300 is the standard. Therefore, the weight of the human body needs to be evenly distributed across the pads.

In consideration of this point, the first and second absorbent pad means 180 and 190 disposed in the hybrid insole 100 of the present invention are formed in different shapes and structures according to respective regions of the human foot 300 .

The first absorbent pad portion 180a of the first absorbent pad means 180 is disposed in a region corresponding to the dome-shaped arch formed by the second, third, and fourth metatarsal bones in the center of the human foot 300 .

The arch region of the metatarsal plays a role in reducing the impact with the ground applied to the front part of the sole, especially when the human body is walking or jogging.

Although the arch region of the metatarsal bone is small, it serves to reduce the weight load generated in the phalanx direction of the sole (anterior direction (F)) by 60%.

Referring to the cross-section taken along line II-II' in FIG. 4 , since the first absorbent pad unit 180a is for supporting the dome-shaped arch of the metatarsal regions F2 and F3, the central region is convex and the inner side (M) ) direction and has a cross-sectional structure in which the thickness becomes smaller toward the outer (L) direction. Accordingly, the first absorbent pad unit 180a may be formed in a heart-shaped, gastrointestinal, and elongate-shaped structure.

The central thickness D1 of the first absorbent pad unit 180a may be set to 5-6 times the thickness D of the insole body 110 . For example, when the thickness of the insole body 110 is 0.5 mm, the thickest central region of the first absorbent pad unit 180a may be formed to be 2.5-3 mm.

In addition, the first absorbent pad portion 180a may be formed in a structure in which the thickness decreases toward the outer (M, L) or front and rear (F, R) edges with respect to the center.

The longest region (vertical side) of the first absorbent pad 180a may be 45 mm, and the lateral side may be 35 mm.

However, this is a description of one embodiment, and the design values may be changed in various forms according to the shape of the human foot, the use environment and conditions, and the like.

In addition, the second absorbent pad unit 180b is disposed at a position corresponding to the medial tarsal region F4 and supports the longitudinal direction of the human foot 300 , that is, the medial longitudinal arch. Since it is a hollow area in the structure of the sole of the human body, if the balance is broken, the center of gravity moves in the inner (M) direction. This causes joint displacement and cartilage deformation, such as internal rotation of the leg bones and distortion of the pelvis.

Therefore, it is preferable that the second absorbent pad portion 180b has a structure in which the edge in the inner (M) direction is highest (thickest) and the height is lowered toward the outer (L) direction.

Looking at the cross-sectional view taken along the line III-III' of FIG. 5A , the right direction is the inner (M) direction and the left direction is the outer (L) direction based on the left foot insole of FIG. 2 . The second absorbent pad portion 180b has an inclined surface (a structure in which the thickness is sequentially decreased) whose height is sequentially lowered from the inner (M) direction to the outer (L) direction.

In addition, when looking at the cross section taken along line A-A' of FIG. 5B cut in the front direction (F) and the rear direction (R), the inner (M) direction area has a high structure as a whole, and the thickness is small in both edge areas It can be seen that the structure is falling.

Accordingly, while the surface is formed in a round shape, it has a three-dimensional long streamlined triangular pyramid shape as a whole (the cross-section is a long triangular shape).

The inner thickest region D2 of the second absorption pad portion 180b may be set to be 11 to 12 times the thickness of the insole body 110 . For example, when the thickness of the insole body 110 is 0.5 mm, the thickest inner region of the second absorption pad unit 180b may have a thickness of 5.5-6 mm. As for the length, the longest area on the longitudinal side can be 85mm and the lateral side can be 30mm.

However, this is a description of one embodiment, and the design values may be changed in various forms according to the shape of the human foot, the use environment and conditions, and the like.

In addition, the third absorbent pad unit 180c is disposed at a position corresponding to the lateral tarsal bone and metatarsal region F2 and supports the longitudinal direction of the human foot 300 , that is, the Lateral Longitudinal arch. Since it is an area adjacent to the second absorbent pad unit 180b and is an area outside the sole of the foot, it has an arch shape opposite to that of the inner longitudinal arch.

In particular, since the outer region of the bottom of the human foot is a part in contact with the ground, the dome has a low height and is formed in an elongated shape.

When looking at the cross-section taken along line IV-IV' of FIG. 6A, the left side is the outward direction (L) and the right side is the inside direction (M). The third absorbent pad portion 180c has an inclined surface whose height is sequentially lowered from the outer (L) direction to the inner (M) direction. In addition, looking at the drawing taken along the line B-B' of FIG. 6B, it can be seen that the outer region has a thick overall thickness because the outer region is cut.

As described above, the third absorbent pad portion 180c has a structure in which the thickness decreases from the outer (L) direction to the inner (M) direction. The thickness D3 of the thickest outer region of the third absorbent pad unit 180c may be 5 to 6 times the thickness D of the insole body 110 . For example, when the thickness of the insole body 110 is 0.5 mm, the thickest outer region of the third absorbent pad unit 180c may have a thickness of 2.5-3 mm.

9A to 9C are diagrams for explaining a mechanism in which the absorbent pad means disposed in the hybrid insole of the present invention absorbs or distributes shock according to the weight of the human body.

Referring to FIGS. 9A to 9C together with FIGS. 1 and 2 , the hybrid insole 100 of the present invention absorbs and distributes a weight load applied to a human foot when a person walks or jogs.

In particular, in the present invention, the insole is manufactured by combining the absorbent pad in the solid form and the absorbent pad in the liquid gel form in response to the change in the amount of impact (force) applied to the sole of the foot during each step of walking due to the weight of the human body.

In addition, the absorbent pads disposed on the hybrid insole 100 of the present invention are formed in different shapes to distribute and absorb the weight load according to the structure and function of the human foot.
