Insole sheet and footwear provided therewith

Technical field

TECHNICAL FIELD [0001] The present invention relates to an insole sheet used by being incorporated in footwear such as sandals, slippers, shoes, and the like, and in particular, a plurality of grooves provided in the insole sheet and a pressure movable groove as a squeeze member provided therein. The lid (hereinafter referred to as the pressure groove lid) moves back and forth in a reciprocating motion when the pressure groove lid warps and restores only when the ground contact pressure increases or decreases due to the movement of the center of gravity. The present invention relates to an insole sheet having a function of giving continuous and complex stimulation to an entire area of an insole sheet by tapping and vibration accompanying reciprocating motion and biting of a groove on a surface layer of a sole, and footwear including the insole sheet.

Background art

[0002] A crucible pushing tool that provides a plurality of pushing projections and gives a cue pushing stimulus to a sole is known (Patent Document 1). A technique relating to a sole stimulating member for pressing or rubbing the sole is disclosed (Patent Document 2). These are intended for the health benefits of improving the blood flow of the soles. The present inventor has also invented various points pushing effects (Patent Documents 3, 4, 5). As described above, various techniques relating to health sandals and health slippers have been known. The conventional sole stimulation method has a problem that the sole becomes painful if it is used for a long time because there are many that stimulate the local area in the vertical direction.

[0003] In particular, as disclosed in Patent Document 2, conventionally, many inventions have been proposed in which stimulation is generated by generating a stimulus using a reaction force of a coil panel or a pressing rod. For example, in Cited Document 2, due to the change in body weight, a pressure is generated due to a difference in air pressure to generate a stimulus.

Disclosure of the invention

Problems to be solved by the invention

[0004] Patent Document 2 has a mechanism for generating a stimulus by moving a strainer by a difference in pressure due to air by increasing or decreasing weight. However, in order to move the shoe by the difference in air pressure, a large drop is necessary to generate pressure, and if the ankle is fixed with the top of the footwear, etc., the increase or decrease in sufficient load is reflected. In addition, no stimulation can be generated in the entire footwear area. In addition, because stimulants protrude from the insole sheet at all times, the soles are paralyzed and may be harmful if used for a long time. Also, those using a coil panel cannot generate an instant tapping stimulus.

[0005] In view of the above, in the present invention, in the movement of the center of gravity, the pressure groove cover moves up and down only by increasing or decreasing the contact pressure of the sole without causing the stimulation mechanism to protrude almost from the surface of the insole sheet. The reciprocating motion of warping and restoration accompanied by speed change generates tapping and vibration and the stimulation of biting on the sole surface layer, and the complex stimulus makes the brain recognize the increase / decrease point of the sole coordinates. It can be used for footwear for various purposes.

[0006] Another object of the present invention is to provide an insole sheet provided with an uneven inversion mechanism (for example, a pressure groove cover) capable of giving an appropriate stimulus to the sole and footwear using the insole sheet. By transmitting vibrations, striking, and shocking sounds that spread laterally across the surface due to local stimulation that pushes up and down, especially in the local area where the soles are pushed up and down, The problem is to provide an insole sheet equipped with an uneven inversion mechanism that can comfortably recognize the increase / decrease point of footwear and footwear using it.

Means for solving the problem

[0007] In the configuration of the footwear in the present invention for achieving the above object, the insole sheet is provided with a plurality of circular grooves, the groove is provided with a pressure groove cover, and the pressure groove cover includes a concentric rim. It has an independent and continuous movable area composed of a plurality of three-dimensional arc shapes (dome shape) installed, and the pressure groove lid is located at almost the same height as the upper part of the insole sheet, and in an upright state The arc shape of the pressure groove cover maintains the shape against the foot contact pressure of the foot, and when the contact pressure of the sole increases or decreases due to weight shift, the pressure groove cover warps and restores independently only at the increase and decrease points. Repetitively, repeatedly struck by rebound and restoration, vibrations accompanied by rapid repulsion speed, and stimuli that bite into the grooves on the surface of the sole of the foot generate a continuous composite stimulus that is sensed by the brain.

[0008] When a load is applied as a member for stimulating the sole, a convex shape force is deformed into a concave shape, and when the load is reduced or released, it has a shape that restores the original convex shape. This can be achieved by using parts. In addition, in order to efficiently convert the unevenness to the entire sole area, a plurality of squeezing members are attached to the rigid elastic plate that constitutes the upper layer of the insole sheet equipped with the unevenness inversion mechanism. The elastic compression plate, which forms the lower part of the elastic plate, compresses and deforms when a load is applied, and the hard elastic plate also deforms into a similar shape. Can be.

The invention's effect

[0009] In the present invention, the pressure groove lid is moved by increasing / decreasing the contact pressure of the vertical load acting on the insole sheet accompanying weight shift, and the movable member is given a shape that can be restored in the vertical direction to the squeezing member. This makes it possible to realize versatility that can be applied to a wide variety of footwear in a thin shape, and to give the stimulus to the pressure groove lid as an independent and correlative movement of the bending and restoring movement of the kneading member. As a result, the effects of tapping, vibration, and biting on the surface of the sole of the foot due to the combined rebound and restoration rebound speeds have a significant effect that can be used for various purposes as medical, sports learning, or healthy footwear. is there.

[0010] Unlike the conventional case, the stimulation received on the sole of the foot is the stimulation of the vertical and horizontal spread of the tapping, vibration, impact sound, and auditory stimulation. In addition, comfortable stimuli can be applied mentally, and the force level of the load can be ascertained, so it can be used as a tool for whether the athlete is performing an appropriate action. For example, if a skier inserts this insole sheet into ski shoes and skis, he / she can grasp where he / she currently puts his weight. Is possible.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiment does not limit the technical scope of the present invention.

FIG. 1 is a top view according to the first embodiment of the present invention. The insole sheet is composed of a hard elastic plate (101) and a pressure groove cover (102). The insole sheet is incorporated in a footwear main body or an insole, and an ankle part such as a member covering the ankle part is provided around the insole sheet. A member for wearing is attached.

[0015] In addition, the number of attachments for arranging a mechanism for generating a stimulus on an insole sheet and the shape and location for generating the stimulus are allocated according to the intended use of the footwear. [0016] For example, when providing a massage function, if the massage function is provided, it is arranged and distributed so that it touches the point, and the center of gravity position is recognized by the stimulus when it is spoken. It is desirable to place it at a point.

[0017] The pressure that is moved by the force in the vertical direction of the pressure groove lid (102) is obtained by, for example, applying pressure that is movable by increasing the ground pressure generated at the time of stepping on the sole when used for sports learning. The brain can recognize the crossing timing.

[0018] FIG. 2 is a side sectional view of the first embodiment of the present invention, in which a pressure groove lid (102) and a pressure groove lid (102) for reflecting a change in ground pressure due to increase / decrease in foot load. 102) is constituted by a groove (103) having a space for warping.

[0019] The pressure groove cover (102) is made of a material made of a squeezing member, and a three-dimensional arc shape (dome shape) is concentrically convexly convex and warped into a concave shape and concavely shaped into a convex shape. It is constructed in an independent shape so that it can be restored, and reciprocally moves back and forth independently and in a correlated manner.

[0020] The arc shape and the joint portion rim (130) configured in concentric and independent shapes are limited to shapes for avoiding damage due to material fatigue by the movement of the squeezing member.

[0021] The movable region that enables the recoil recovery concentrically provides at least one movable region that can be warped.

[0022] Fig. 3 is a top view of the main part in the first embodiment. The convex pressure groove lid (102) is formed by concentric rim (130) by increasing or decreasing the contact pressure on the sole. The first warpable region (110) and the second warpable movable region (120) that allow warping in a concave shape at the boundary are shown.

[0023] The first warpable region (110) and the second warp movable region (120) are capable of independently returning to a concave shape and restoring to a convex shape. In the process of warping up and down !, the joint rims in both areas become continuous movement with up and down movement.

[0024] The pressure groove cover (102) is made of a material that can be warped and restored, and has a rebounding repulsive force. On the other hand, it is made of durable material.

[0025] The distance in the reciprocating motion of the warping restoration is less than 2 mm, and it can generate vibration and vibration. The pressure groove cover (102) can be configured by a combination of materials desired for the material.

[0026] In the concentric region that allows the pressure groove lid (102) to be warped, the first warp movable region (110) and the second warp movable region (120) are assembled in the member. The combination may be the same material or a combination of different materials. In addition, the thickness of the pressure groove lid (102) in the pressure resistance against the vertical load is not necessarily constant. For example, the first warpable region (110) is thickened and the second warpable movable region (120) is thinned. As a result, various warping motions can be realized.

[0027] The pressure groove lid (102) is composed of a kneading member whose upper surface has a circular shape with a diameter of about 6 mm to 15 mm. However, when the area of the upper surface increases, The area of the upper surface of the pressure groove cover (102) is determined according to the intended use of the footwear. In addition, since the stagnation member constituting the pressure groove lid (102) has a difference in stagnation resistance depending on the material used, the pressure groove lid (102) depends on the material attribute and material combination of the stagnation member and the thickness of the material. The area of 102) is limited.

[0028] In particular, if the pressure groove lid (102) is large in the bent portion of the footwear, the kneading member independently disposed on the footwear is damaged due to the difference in hardness of the material resistance due to the deformation of the footwear accompanying the bending. In this case, it is desirable that the circular area on the upper surface of the squeeze member constituting the pressure groove lid (102) is made small so that it can be bent back and restored and attached to the insole sheet.

[0029] The circular shape on the upper surface of the pressure groove lid (102) is not necessarily circular. For example, an oval shape may be used as long as the stagnation member constituting the pressure groove lid (102) can be bent back and restored.

[0030] Fig. 4 is a side sectional view of the main part in the first embodiment. The first warp movable region (110) and the second warp movable region (120) are stepped in an arc shape. It is formed on the heel and repeats warping and restoration while correlating with changes in the contact pressure on the sole.

However, the shapes of the first movable area and the second movable area are not necessarily different.

The steps can be eliminated by the shape of the rim connecting the two regions.

[0032] FIG. 5 is a side sectional view of the main part at the time of operation in the first embodiment, and shows the first warp movable region (110) and the second in the course of increase / decrease in the contact pressure of the sole. Of movable area (120) The state in the relative deformation is shown, and the first warp movable region (110) is greatly warped, and the second warp movable region (120) is shown to be in a state where the force is warped.

[0033] The order in which the first warp movable region and the second warp movable region are warped with respect to the vertical load is the shape, area, thickness, and material of the squeeze member constituting the pressure groove lid (102). In combination, the order in which the warping occurs is reflected, and the warping continues while maintaining a combined and complex relationship.

[0034] At least one region that can be bent back is provided in a concentric shape, and at least three regions that can be turned back are preferably provided. Hope to give you.

[0035] FIG. 6 is a side sectional view of the main part at the time of operation in the first embodiment, showing a state when the ground contact pressure of the sole is maximized, and shows the first movable region and the second movable region. This shows that the movable region of the first and second movable regions is grounded at the bottom of the groove (103), and the central portion of the first and second movable region is grounded.

FIG. 7 shows a configuration in which a plurality of pressure groove lids (SW1 dome to SW6 dome in FIG. 7) having different surface areas are arranged on an insole sheet (101) having a hard elastic plate force. Since the pressure groove lid is a plate panel having a dome shape, it is also called a dome spring.

[0037] SW2 dome, SW3 dome, and SW6 dome are large portions of the sole load, and the dome area

By reducing the (surface area of the pressure groove lid), the amount of sagging of the sole surface layer can be reduced, the biting pressure reflected on the dome can be controlled, and the power contact circuit can be easily opened and closed.

[0038] Further, it is not always necessary to control the support pressure against the vertical load depending on the dome area, and the dome shape and the dome thickness may be controlled to be different even in the same dome area.

[0039] Figs. 8 and 9 show the difference in the amount of foot erosion, the amount of foot erosion and the foot foot erosion and the foot erosion pressure at the horizontal level of the insole sheet (101) according to the first embodiment. Indicates a difference.

FIG. 8 shows a state in which the amount of sagging of the sole surface layer where the groove area is larger than that in FIG. 9 and the pressure at the seat horizontal level are larger than those in FIG. In this case, the amount of biting X is greater than Y. [0041] FIG. 10 is a side sectional view of the main part at the time of operation in the first embodiment, and a dome-shaped pressure groove lid (SW dome) (102) bites into the surface layer portion (190) of the sole. The power connections (170) and (180) are turned off.

[0042] In this case, the amount of biting into the dome portion of the pressure groove lid (102) on the sole is a slight amount of about lmm, and does not give an uncomfortable feeling even when used for a long time. However, the dome height is preferably about 0.4 mm.

[0043] Fig. 11 is a side sectional view of the main part at the time of operation in the first embodiment. The soft part of the sole surface layer part is caused by the increase or decrease in the ground pressure of the sole surface layer part due to weight movement. The thickness of the skin) is deformed and thinned, and the relatively hard soles such as muscles and tendons inside the skin push down the top of the dome, and the balance of the support pressure that maintains the dome shape of the pressure groove lid is broken. This shows the state where the power is turned on (conduction state) when the carbon (160) attached to the ceiling of the dome is connected to the power connection parts (170) and (180). That is, the carbon (160) and the power supply connection parts (170) and (180) constitute a switch circuit.

[0044] By using the ON / OFF of the switch circuit where the physical stimulus of vibration and tapping is generated, electricity is converted into sound or light, for example, playing a melody on the sole of the foot, or Attach the same number of signal lights as the connection switch to the upper part of the footwear to make the direction of center of gravity movement self-recognizable, and it can be applied for various purposes such as sports training shoes or nursing care and medicine.

Next, a second embodiment of the present invention will be described. 12 to 18 show a second embodiment of the present invention!

[0046] As shown in Figs. 12 to 18, the insole sheet having the kneading member disposed on the surface is applied to the insole, shoes, sandals, slippers, socks, or the like worn by the foot, and the kneading member (2) And a rigid elastic plate (1), an inversion groove (10), a deformation prevention plate (20), an elastic compression plate (3), a pressure adjusting space (7), and a bottom material (4). The stagnation member (2) squeezes so that it can bend when pressure (sole load) is applied, such as a pressure groove lid or plate panel. It consists of a member that repels and restores.

FIG. 12 is a top view of the first embodiment of the present invention. Rubbing member (pressure groove lid ( The insole sheet with a dome spring)) is provided with a hard elastic plate (1) and a plurality of squeezing members (2) that generate stimuli depending on the purpose of use. It can be used as an insole, or can be sanded and integrated into footwear, and used for all types of footwear such as sandals and slippers.

FIG. 13 is a side sectional view of the second embodiment of the present invention. In order to prevent the load from concentrating locally due to the increase or decrease of the sole load, the stagnation member is prevented. (2) Elasticity to adjust the height of the non-contact surface such as arches by lifting and sinking with the increase and decrease of the foot load and the layer made of rigid elastic plate (1) for smooth warping and restoration It consists of a layer consisting of a compression plate (3), and the bottom (4) is attached to the lower part. By providing a layer of elastic compression plate (3), the sole can be brought into close contact with the rigid elastic plate (1) according to the shape of the sole, and it is arranged on the rigid elastic plate (1). The sole load can be efficiently applied to the kneading member (2).

[0049] Fig. 14 is a sectional side view of the main part of the second embodiment of the present invention, in which the hard elastic plate (1) is a material having the characteristics of stagnation and restoration, and is localized in the vertical direction. Distributes the load with respect to the load, prevents the elastic compression plate (3) from being extremely compressed, and provides walking safety.

The optimal thickness of the rigid elastic plate (1) is about 0.3 to 0.75 mm. For example, a material that does not break during punching, such as polypropylene, is desirable, and it can exhibit performance in response to changes in temperature. Composed of materials.

[0050] The material of the stagnation member (2) is a material that is corrosion resistant, has a repulsive force, and can be restored repeatedly.

For example, it is made of stainless steel or a resin such as Lumirror T60.

[0051] The shape of the stagnation member (2) is optimally set to a deformation height of about 0.4 mm to 0.8 mm in the vertical direction where a circular dome shape is desired. But it is not a requirement.

[0052] When the stagnation member (2) is formed into a circular dome shape, the ceiling of the dome is flat as much as possible to avoid excessive stimulation on the sole, and stagnation and restoration near the outer circle. It is desirable to provide a shape that can

[0053] The size of the kneading member (2) is optimally, for example, in the case of a circle, a diameter of about 8 mm to 15 mm. However, if it is placed on a bent part of footwear during walking, it will be damaged. Do n’t be afraid, It is necessary to select a smaller dimension.

[0054] The thickness of the squeeze member (2) is preferably about 0.1 mm for the 0.08 mm force from the viewpoint of warping and impact when restored, for example, when stainless steel is used.

[0055] The yield point where the stagnation member (2) is warped and restored by the stress change accompanying the center of gravity movement of the sole of the foot is a correlation between the pressure change accompanying the expansion and contraction of the elastic compression plate (3) and the warp strength. That is, for example, when the repulsive pressure of the elastic compression plate (3) becomes substantially larger than the rebound strength of the stagnation member (2), the stagnation member (2) is warped, and vice versa.

[0056] In this case, the compression of the elastic compression plate (3) that the deformation prevention plate (20) does not come into contact with the bottom material (4) by the pressure adjustment space (7) is saturated, and the deformation prevention plate (20 ) And the squeezing member (2) are relatively pushed up, and there is no sense of incongruity.

[0057] The pressure adjustment space (7) is not necessarily a space. For example, materials with low elastic volume ratios and low resistance can be substituted with materials or fluids! /.

[0058] The reversing groove (10) is a region having a height that allows the stagnation member (2) to warp. Depending on the shape of the squeezing member (2), the reversing groove (10) is not necessarily provided. May not need

. In other words, the dome-shaped stagnation member (2) may be arranged on the plane of the insole sheet.

[0059] However, in this case, the stagnation member (2) is disposed at a position higher than the horizontal height of the insole sheet, which may cause a sense of incongruity and is immediately provided with a reverse groove (10) as much as possible. It is desirable to arrange them smoothly.

[0060] FIG. 15 is a side sectional view of the main part at the time of operation in the first embodiment of the present invention, in which the vertical load increases, the elastic compression plate is compressed, and the expansion / contraction pressure in the elastic volume ratio is stagnant. When the buckling strength of the member (2) is greater, the stagnation member (2) buckles and warps. Also, it is desirable that the strength range of the squeezing member (2) at the yield point of buckling strength is weaker than the repulsive pressure at the time of maximum compression of the elastic compression plate (3).

FIG. 16 shows a region in which the sole area increases or decreases due to the pressure of the vertical load in the second embodiment of the present invention. Region A is the ground contact area when the ground contact pressure of the load on the sole is weak, and the ground contact area increases as the load increases with regions B and C. Indicates.

[0062] In this case, the stagnation member (2) arranged in the B and C regions causes an increase or decrease in pressure on the stagnation member (2) due to the increase or decrease in the contact area of the sole and the elastic compression plate sinking. Then, warping and restoration begins.

[0063] Fig. 17 is a side sectional view of the second embodiment of the present invention at the time of operation, and in the initial stage of load operation, the X region of the elastic compression plate (3) is compressed in a state where it is stepped forward, The bending member (2b) is warped, and the bending members (2c) and (2d) and the elastic compression plate (3) in the ridge and Z region are restored.

FIG. 18 is a side cross-sectional view of the second embodiment of the present invention during operation, showing a state when a load force is applied to the entire sole, and includes a hard elastic plate (1) and an elastic compression plate. (3) shows a state in which the shape of the foot is deformed and the stagnation members (2b), (2c) and (2d) are warped.

Next, a third embodiment of the present invention will be described.

FIG. 19 to FIG. 21 show a third embodiment of the present invention. As shown in FIG. 19 to FIG. 21, the insole sheet equipped with the concave / convex reversing mechanism (pressure groove cover (also called dome spring)) has the ability to be worn with feet such as insole, shoes, sandals, slippers or socks.

FIG. 19 is a sectional side view in the third embodiment of the present invention. Since the pressure adjustment space (7a) is located up to the lower part of the hard elastic plate (la) and the deformation preventing plate (20a), With the increase or decrease of the load, the warpage is due to the correlation between the amount of stagnation with respect to the horizontal distance of the rigid elastic plate (la), the value of the bulk modulus of the elastic compression plate (3a), and the warping strength of the stagnation member (2a). Restore.

[0068] In this case, the bending strength of the squeezing member (2a) is weak! Even with a material such as silicon, the elastic elastic plate (la) squeezes so that the elastic compression plate (3a) functions as a cushion. And delaying the timing of warping can cover the weakness of warping.

FIG. 20 is a side sectional view of the third embodiment of the present invention, in which the pressure adjustment space (7a) is narrowed by the compression of the elastic compression plate (3a) and the stagnation of the stagnation member (2). The rubbing member (2a) is warped.

FIG. 21 is a cross-sectional side view of a main part in an example of production according to the third embodiment of the present invention, in which the sand cover (80) is composed of a rigid elastic plate (la) and a stagnation member (2a). And a state where the deformation prevention plate (20a) is sanded. In the lower part, the elastic pressure is the same as in the above embodiment. Manufactured with shrunk plate and bottom material. For example, the material of the sand cover is preferably a soft material such as silicon.

[0071] In this case, for the transmission of the stimulus accompanying the warping and restoration of the kneading member, for example, in the case of silicon, if the thickness is around 2 mm, the tapping, vibration, and impact sound are caused by a small amount of transmission loss. I can tell you. Moreover, the impact sound can be eliminated by replacing the material of the rubbing member with silicon or a soft material.

[0072] When the stagnation member is covered with a hard material, the transmission of stimulation is extremely reduced. Therefore, it is desirable to cover only the stagnation member part with a material that does not hinder movement or a shape similar to that of the stagnation member. Good.

[0073] FIG. 22 is a top view of the fourth embodiment of the present invention, comprising a hard elastic plate (lb), a through hole (40), and an impact transmission body (30)! Speak.

FIG. 23 is a side sectional view of the fourth embodiment of the present invention. A soft elastic plate (60) is provided between an upper hard elastic plate (lb) and a lower elastic compression plate (3b). ), And built-in kneading members (50a) and (50b) in a room with multiple movable reversal spaces (70). When the squeezing member (60) expands and contracts, the built-in squeezing members (50, (50b) are warped and restored, and the impact transmitting body (30) is moved up and down to give a stimulus.

[0075] The soft elastic plate (60) is made of a soft material such as silicon or soft plastic, and the inversion space (70) and the built-in squeeze member (50, (50b)) A material that can be molded is desirable, and when it is integrally molded, it is desirable to make a split mold with the sand deformation prevention plate (5) as the boundary.

[0076] FIG. 24 is a sectional side view of a main part in the fourth embodiment of the present invention, and shows a structure of a soft elastic plate (60) sandwiched between a hard elastic plate (lb) and an elastic compression plate (3b). Built-in squeeze member (50a), (50b), shock transmission body (30), sand deformation prevention plate (5), (5, 5b), through hole (40) and elastic compression plate (3b), a bottom material (4b), and a pressure adjusting space (7b).

[0077] The elastic compression plate (3b) is not necessarily like a sponge. For example, an infinite number of gap holes may be provided in the soft material and expanded or contracted. [0078] Further, the material of the impact transmission body (30) can make the sole more desirable to fit the material having the same characteristics as the material of the hard elastic plate (lb) as much as possible.

[0079] FIG. 25 is a side sectional view of an essential part at the time of operation in the fourth embodiment of the present invention, and the hard elastic plate (lb) is deformed downward due to a change in the ground contact pressure due to weight shift. When the soft elastic plate (60) is compressed, the width is reduced, and at the same time, the elastic compression plate (3b) is also compressed. (50, (50b) is pressed by the sole of the foot, so that the built-in rubbing members (50a), (50b) are bent and warped.

[0080] In this case, the order in which the built-in stagnation members (50a) and (50b) warp is the shape of the stagnation member, or! , Is determined by the strength of warping due to thickness, and it doesn't matter if it warps in any direction.

[0081] The number of built-in squeeze members (50, 50b) arranged vertically in a multistage manner for striking the impact transmission body (30) is preferably two or more, but may be one.

[0082] Further, in order to repeatedly strike the impact transmission body (30), the flexible elastic plate (60) needs to be expanded and contracted to a certain extent, for example, to increase the space volume of the inversion space (70). Therefore, expansion and contraction can be increased.

[0083] The sand deformation prevention plate (5) prevents deformation so that the built-in squeeze members (50, 50b) can be uniformly squeezed and reversed, and is resistant to impact and torsion, for example, high strength, plastic It is composed of.

FIG. 26 is a diagram showing a fifth embodiment of the present invention. In the fifth embodiment, the fifth embodiment uses the stagnation of the hard elastic plate (1) itself. In other words, in the rigid elastic plate (1) of the insole sheet, the part where the sole load exceeding the predetermined pressure in the vertically downward direction is rubbed is stiffened, and when the sole load disappears from the force, the original shape is restored. By restoring, the stimulus is transmitted to the sole. As shown in FIG. 26, in the insole sheet having a three-layer structural force of the hard elastic plate (1), the elastic compression plate (3), and the bottom material (4), a hole (90) is formed in the layer of the elastic compression plate (3). ) And provide a space where the space below the rigid elastic plate (1) is. While the space is compressed like the elastic compression plate (3), it cannot support the pressure from the hard elastic plate (1), so a vertical downward pressure is applied to the hard elastic plate (1). When , That part will be larger.

[0085] When the sole load increases or decreases based on the change in the center of gravity, the support force of the rigid elastic plate (1) against the vertical downward stress due to the sole load changes, so that the space of the elastic compression plate (3) Depending on the top surface area and depth, the rigid elastic plate will stagnate (Fig. 26 (b)) and restore (Fig. 26 (a)) in the space, and the deformation of the rigid elastic plate (1) Is transmitted as a stimulus to the sole. Specifically, in the hard elastic plate (1), the depth of the portion on the elastic compression plate (3) and the portion on the hole (90) when the sole load is strong Is different, and the part on the hole (90) falls more quickly into the hole (90). Following the fall of the hard elastic plate (1), the surface layer of the sole is also deformed so as to eat into the fall, and the deformation is transmitted to the sole as a stimulus. The cross-sectional area and depth of the hole (90) can be adjusted as appropriate.

FIG. 27 is a diagram showing a sixth embodiment of the present invention. The sixth embodiment is an example in which a dome-shaped pressure groove lid is provided in the hole (90) (in the space) of the elastic compression plate in the fifth embodiment shown in FIG. The bottom surface of the rigid elastic plate (1) is in contact with the protrusion (91) provided on the dome ceiling of the stagnation member (2) (Fig. 27 (a)), and the rigid elastic plate (1) According to the stagnation, the stagnation member (2) also warps (Fig. 27 (b)), and when it is restored, the stagnation member (2) is restored together with the hard elastic plate (1). At this time, the striking member (2) is struck by the rebounding and restoring motion, and vibration is transmitted to the sole as a stimulus.

[0087] When the rigid elastic plate (1) is squeezed, the mounting base (92) of the rubbing member (2) hits the rigid elastic plate (1) and the mounting base (92) is rigid. Various parameters such as the cross-sectional area and height of the hole (90) in the elastic compression plate (3) and the hardness of the rigid elastic plate (1) are set so as not to disturb the stagnation of the elastic plate (1). It is necessary to decide. The mounting base (92) is formed of the same material as the elastic compression plate, for example.

FIG. 28 is a diagram showing a seventh embodiment of the present invention. The seventh embodiment is an example in which the dome-shaped squeezing member (2) is provided in a multistage manner in the sixth embodiment shown in FIG. The number of stagnation members (2) according to the amount of settlement due to the sag of the rigid elastic plate (1) is configured to warp. The number of stagnation members (2) that warp changes depending on the magnitude of the sole load, and the number of hits on the sole varies. It becomes possible to feel. Fig. 28 (a) shows a configuration in which the stagnation member (2) is provided in two stages in the vertical direction, and Fig. 28 (b) shows a two-stage sag due to the stagnation of the rigid elastic plate (1). This shows the state in which both the two members (2) are warped. The rubbing member (2) and the mounting base (92) are integrally formed in a capsule shape, for example, and can be embedded as a capsule in the hole (90) and can be easily replaced.

FIG. 29 is a diagram showing an eighth embodiment of the present invention. The eighth embodiment is the same as the sixth embodiment shown in FIG. 27 except that a protruding portion (91) is provided at the dome portion of the stagnation member (2) on the dome, and the tip of the protruding portion (91) is provided. In the horizontal state where the hard elastic plate (1) is not stiff, the portion has a height that does not protrude the surface force of the hard elastic plate (1), and the opening (93) provided in the hard elastic plate (1) ) Power Exposed. When the rigid elastic plate (1) is squeezed by the sole load, the squeezing member (2) is warped by pushing down the protrusion (91) of the squeezing member (2). In the eighth embodiment, the striking stimulus due to the warping and restoration of the kneading member (2) is transmitted directly to the sole of the foot via the protrusion (91) that does not go through the rigid elastic plate (1). Is done. In addition, the protrusion (91) does not protrude from the surface of the hard elastic plate (1) when it does not fold, so it does not give any irritation and the foot load is strong only. Gives the soles a beating stimulus by warping and restoration.

FIG. 30 is a diagram showing a ninth embodiment of the present invention. In the ninth embodiment, a plurality of dome-shaped (convex-shaped) squeezing members (pressure groove lids) (2) are arranged on the surface of the rigid elastic plate (1). When a sole load exceeding a predetermined pressure is applied, the convex shape is warped to a concave shape. The deformation of the sole when the kneading member (2) is deformed into a convex force will be described with reference to FIG.

FIG. 31 is a diagram for explaining the relationship between deformation of the kneading member (2) into a convex shape and a concave shape and deformation of the sole. In FIG. 31 (a), the convex kneading member (2) bites into the sole in a state where the sole load not exceeding the predetermined pressure is not applied. Specifically, it bites into the dermis mesh layer (94), the surface layer of the sole. The reticulated layer (94) is a relatively soft layer on the surface layer of the sole that contains a lot of blood and lymph, and when pressure is applied, blood and lymph fluid escapes to a lower pressure area. Compressed easily. In Fig. 31 (a), the portion of the mesh layer on the sole that is in contact with the rigid elastic plate (1) is also Although it becomes thinner (becomes high pressure) due to the back load, the portion of the mesh layer (94) in contact with the stagnation member (2) is more compressed and thinned by the height of the convex stagnation member (2). Has become higher (higher pressure). However, as long as the foot load increases, the mesh layer (94) on the surface layer of the sole does not increase the sole load unless the vertical downward foot load applied to the kneading member (2) exceeds the specified pressure. By absorbing and becoming thin while becoming high pressure, the stagnation member (2) is not applied with pressure sufficient to reverse the unevenness, and the stagnation member (2) does not warp into a concave shape. Although the pressure in the mesh layer is high, there is still a place for lymph and blood to escape, and pressure is absorbed by deformation of the mesh layer. That is, as long as the mesh layer can be deformed to absorb pressure, the stagnation member (2) does not warp into a concave shape.

[0092] When the vertical downward foot load applied to the stagnation member (2) exceeds a predetermined pressure, the mesh layer (94) is in the thinnest state where it cannot absorb the foot load any more. At this time, the kneading member (2) is pushed down by the muscles and tendons (95) of the soles inside from the mesh layer (94) (see FIG. 31 (b)). The muscles and tendons (95) of the sole are harder than the mesh layer (94), and are less deformed and absorb pressure than the mesh layer (94). Therefore, when a predetermined pressure exceeding the pressure at which the mesh layer (94) reaches its thinnest state is applied, the muscles and tendons of the sole (95) push down the itching member (2), and the itching member (2) Warps into a concave shape.

[0093] When the stagnation member (2) warps into a concave shape, the portion of the mesh layer (94) in contact with the stagnation member (2) that has been compressed to the limit is the convex shape of the stagnation member (2). Since the internal pressure decreases due to the deformation from the concave shape to the concave shape, the lymph fluid and blood flow into the portion of the mesh layer following the deformation of the stagnation member (2) from the convex shape to the concave shape. Thicker than the thinnest state!

[0094] The convex force of the stagnation member (2) also follows the deformation to the concave shape, and the mesh layer, which is the surface layer portion of the sole that contacts the stagnation member (2), is deformed into irregularities. , Stimulation is given to the soles. In the reticulated layer, there is a nipple with a tactile receptor in addition to lymph fluid and blood, and the tactile material (2) is inverted to stimulate the tactile receptor and the muscles and tendons to move the center of gravity. The point is transmitted to the brain.

FIG. 32 is a view for explaining the relationship between the conventional foot heel pressing health sandals having protrusions that do not invert unevenness and the deformation of the soles. Fig. 32 (a) shows the projection (96) provided on the hard elastic plate (1) when the vertical downward foot load is below a predetermined pressure. The protrusion (96) provided on the elastic elastic plate (1) bites into the mesh layer (94), but lymph fluid or blood in the mesh layer of the sole contacting the protrusion (96) escapes to other parts. In addition, the foot load in the vertically downward direction is absorbed by the compression of the mesh layer (94).

[0096] FIG. 32 (b) shows a case where the vertical downward foot load exceeds a predetermined pressure, exceeds the pressure that can be absorbed by the mesh layer (94), and the thickness of the mesh layer is the thinnest. Then, since the mesh layer cannot absorb any more downward pressure, the muscles and tendons on the inside of the foot press the projection (96) from the mesh layer (94). However, since the protrusion (96) is not reversed and is fixed to the rigid elastic plate (1) and does not deform, the protrusion (96) substantially compresses the internal muscles and tendons, thereby It is obvious that the acupressure effect is applied to the tendon, which is applied to the sole as a stimulus, and is different from the present invention in terms of structure, action and effect.

[0097] The height of the kneading member (2) is required to be lower than the thickness of the mesh layer (94) of the sole when the kneading member (2) is convex, preferably lmm or less (optimum Is about 0.4 mm to 0.7 mm). With this height, the muscles and tendons inside the mesh layer are not compressed and the thickness of the mesh layer is increased or decreased to absorb the height of the kneading member (2), making the sole feel uncomfortable. Don't give. Then, when the sole load is applied to the stagnation member (2), the mesh layer is initially compressed and thinned to absorb the load, but the limit thickness is such that the mesh layer cannot be further thinned. When reaching the thinnest state, the stagnation member (2) is warped by pushing down the dome part of the stagnation member (2) with a relatively hard sole layer such as muscles and tendons inside the mesh layer. Dent. Since the dent is made within the range of the height of the dome portion of the stagnation member (2), it is not necessary to provide a groove below the stagnation member (2). As described above, it is not necessary to provide a groove under the rubbing member.

[0098] As described above, the insole sheet of the present invention and the footwear provided with the insole sheet include the kneading members provided at a plurality of locations on the surface of the hard elastic plate that is in close contact with the sole, and the soft layer of the sole (Reticulated layer) is compressed to absorb the vertical downward foot load, but when the foot load exceeds the specified pressure, it is relatively hard! Bending the bending member, and when the sole load becomes less than the predetermined pressure, the bending member is restored to its original shape, and the surface shape of the sole is also deformed following the warping and restoring deformation. To do. The deformation of the surface shape of the sole is given to the sole as a tapping stimulus, so that the change in the sole load, that is, Changes in the movement of the center of gravity are transmitted to the brain as a stimulus.

[0099] In the present invention, the stagnation member (2) has a dome-like convex shape in a normal state where it does not warp, and is thinner and thicker than the mesh layer (94). 94) bites into the itching member (2), so the distance between the itching member (2) and the muscles and tendons (95) of the soles becomes close, and the slight pressure change causes the itching member ( 2) can be turned back and forth. Therefore, it is possible to make the brain recognize the position of the maximum load on the foot instantaneously with a powerful movement of the body.

[0100] The insole sheet of the present invention may be configured to be detachably attached to the footwear, or may be configured integrally with the footwear as an insole of the footwear.

[0101] The insole sheet of the present invention and footwear using the same are footwear used in daily life such as health sandals, and footwear that requires analysis of center of gravity movement in sports such as skiing and athletics (ski shoes) ) And can be used in a wide range of fields. It is also effective for lymph pine surge.
