Description

  The present invention relates to a walking aid to be worn on a walking shoe in walking performed as an exercise for maintaining and improving physical strength, and more particularly to a walking aid to be worn on the arch portion of the sole of the walking shoe.

  Walking as exercise for health is called walking, and a method of walking on various roads at an appropriate speed and time is performed, and various shoes have been developed for walking. . Furthermore, in these walking shoes, the movement of the legs during walking is captured by the shape of the legs from the hip joint and the shape from the toes to the buttocks of the shoe sole. Ideally, the movement should be an arc shape from the ideal hip joint. However, in order to walk with this body shape, it is possible to devise a support device that makes walking more comfortable and more useful for health, and to put this support device on the sole of walking shoes is a conventional walking It hasn't been done for shoes.

  In contrast to conventional shoes for walking exercise, there has been proposed one in which a structure having a hardness different from that of a shoe sole is sheathed on an arch of the shoe sole (see, for example, Patent Document 1). Although this thing gives the pressurization effect to the whole arch, it does not become the movement of the circular body shape from the crotch joint at the time of the above-mentioned walking.

  In addition, there is a type in which a semi-cylindrical hard material is attached to or detached from a shoe arch (see, for example, Patent Document 2). This thing enables the acupressure effect and rhythmic walking, but this thing is not intended to be an arc-shaped body movement from the groin during walking as described above.

  Further, there has been proposed footwear in which the arch portion of the shoe sole is in a flat state and bulges along the arch on the insole sheet in the shoe (see, for example, cited document 3). However, this one has a flat bottom surface of the arch on the shoe itself, and is not a retrofitted exterior, and if the bottom surface of the arch is flat, it is It cannot be an arc-shaped body movement.

  Furthermore, there is proposed an auxiliary tool for walking on a hill that is attached to a shoe sole, and an auxiliary tool provided with a convex portion under the center of the gantry can be attached to the shoe with a band (for example, cited reference). 4). However, this is used for climbing up and down hills such as mountain climbing, so that the hill during climbing can be walked with the same body shape as when walking on a flat road, not a biased load, but a balanced It is designed to apply a heavy load to the feet. However, this does not facilitate the rolling of the shoe sole to the road surface even when used on a flat road, and it is attached to the shoe sole of the shoe for walking on a flat road for health and walking. Sometimes it is not intended to make the arcuate body shape move smoothly from the hip joint.

  It is defined as follows about what kind of desirable walking is (for example, refer nonpatent literature 1). According to it, (1) 癖: A posture without distortion, that is, even when walking with a distortion that is a heel that has permeated the body for a long time without knowing it, it causes fatigue and pain. Raise the palms of your hands over your head, lift your entire body up and stretch it out, then lower your hands and heels. The neck and back are stretched, the chest is stretched, and the abdomen is tightened. Walk with this posture. Keep your eyes on the front and keep the scenery high enough to enjoy the scenery. (2) Extending the knee: Stretch the knee well when you swing out your forefoot, and land straight from the heel when you are fully extended. If the knee is still bent, the stride will be narrowed, and it will land on the entire sole of the foot, making it a sticky walk. Make sure that the back of your hind legs are extended to the back of your knees. Finally, if you step on your 5 toes and step on them while kicking with your thumb, the rebound will return to your hips and your hips will be pushed forward. , Hip joints are expanded, stride is further increased, and posture is also beautiful. (3) Moving the center of gravity so that the sole of the foot rolls: When the heel of the forefoot has landed, the weight is moved toward the thumb so that it rolls smoothly using the muscles of the shin. Try to follow the movement of the outer arch, foot core, base, and center of gravity from the heel with consciousness, and finally use the toes to grab the ground with five toes. (4) Stride length is 1/3 to 1/2 of the height: In other words, the expected stride length is 1/3 of normal height and 1/2 of speed. The stride of a person with a height of 170 cm is 56 centimeters from the heel to the heel and 84 centimeters when two feet are included. However, walking shoes suitable for walking that realize these ideals have not yet been realized.

  In general, when walking while supporting the body load, the walking movement of the shoe sole draws an arc centering on the crotch joint, so that the weight shift of the shoe sole during walking is smooth from the heel to the toes. It is ideal to do. By attaching the aid set to follow this ideal to the sole of the walking shoe, the inventor can smooth the weight shift of the sole part during walking from the heel to the toe. Heading.

  Therefore, the problem to be solved by the present invention is to enable comfortable walking in which the foot is moved from the hip joint to the large crotch, and by applying appropriate pressure to the arch portion of the sole. It is intended to provide a support device for attaching to a shoe sole made of a support that can activate the circulation of venous blood flow in a part and can directly contribute to health.

The means of the present invention for solving the above problems will be described below. According to the first aspect of the present invention, there is provided a walking aid having a support attached to the sole of a walking shoe, and the support is formed of an elastic rubber material whose front and rear ends are thin and whose center is thick. The shoe sole has a size that covers the arch portion of the shoe sole, and is made of a material that deforms into a shape that follows an arc drawn with a radius from the hip joint to the shoe bottom when walking. In walking grant instrument to have a ring lifting in the widthwise end portion of the support, the ground powder of walnut shells and chaff to the elastic rubber material support made of an elastic rubber material for the slip prevention of the compacted snow road surface or frozen road in winter This walking aid is attached to the sole of a walking shoe made of a kneaded and molded article .

In the invention of claim 2, the support made of an elastic rubber material compensates for the depth when the arch portion of the shoe sole is deep, and a plurality of sheets whose length in the shoe length direction is shortened stepwise. It is made of an elastic spacer having a constant thickness, and is formed from a support body in which these spacers are laminated and integrated on top. 2. The walking shoe shoe according to claim 1, wherein the spacer laminated integrally with the support body deforms the support body into a shape following an arc drawn by a radius from the hip joint to the shoe bottom surface during walking. It is a walking aid attached to the bottom.

According to a third aspect of the present invention, the elastic rubber material forming the support is a material having a flexible elasticity that follows the movement of each part of the shoe sole together with the hardness that reliably transmits the load reaction force received from the road surface during walking to the shoe sole. It is made up of. Further, the support made of this elastic rubber material has a width of 2 to 4 times the thickness of the support and a depth of ½ of the thickness of the support in the width direction and the length direction from the center to the upper surface of the support. A cross-shaped groove is formed to divide the upper surface of the support into four parts. The walking aid according to claim 2, wherein the support divided into four parts is easily curved in accordance with the movement of the shoe sole.

According to a fourth aspect of the present invention, the cross-shaped groove has a plurality of narrow grooves having a large groove width in the groove longitudinal direction of the groove bottom surface with appropriate intervals in an interdigital manner. The support divided into four by the interdigital narrow groove is more easily curved. By dividing into 4 parts, the reaction force of the load from the road surface that tends to concentrate on the center of the arch of the shoe sole is distributed throughout the arch, and the hardness and elasticity of the support body that does not hinder the free movement of the shoe sole during walking can be obtained. It is a walking aid attached to the sole of the walking shoes in the means of Claim 3 .

  Since the present invention is the above-mentioned means, by attaching the support of the walking aid to the arch portion of the walking shoe, along the arc drawn by the radius from the hip joint to the shoe sole, The support that has the hardness and elasticity that can be easily walked by shaping it into the ideal arc shape above that moves the shoe sole with large crotch, and that can give an appropriate compression force to the arch of the sole In addition, the support body can be bent freely by providing a cross-shaped groove in the support body and a narrow groove in the bottom of the groove, and wear walking shoes having this support body on the shoe sole. The foot can move freely, and as a result, the circulation of the venous blood flow in the foot can be activated, which can be useful for health. Even so, because the spacer with the size matched to the concave part of the arch was laminated and integrated on the support body, the venous blood flow in the foot part was made by contacting the road surface with the arch part of the shoe sole at an appropriate contact surface. The present invention has an excellent effect such that the circulation of the water can be activated.

  Embodiments of the present invention will be sequentially described with reference to the drawings. First, in the means of the invention according to claim 1, the walking aid 3 attached to the sole 2 of the walking shoe 1 has a support body 5 attached to the arch 4 portion of the sole 2 of the walking shoe 1. . As shown in FIG. 1, the aid 3 has a support 5, and the front end 5 a and the rear end 5 b of the support 5 are thin elastic rubber materials having a thickness of about 2 mm. The center 5c is made of an elastic rubber material having a thickness of about 6 mm. The size of the support 5 is a size that covers the arch 4 of the shoe sole 2 and is rectangular. The elastic rubber material of the support 5 can be deformed and bent into a shape that follows an arc 10 drawn by a radius 9 from the hip joint 8 to the shoe bottom 2a when walking with the walking shoe 1 with the support 5 attached to the shoe sole 2. It is a material. Furthermore, a lifting ring 11 is provided at each of the left and right width direction ends 5 e of the support 5. The left and right lifting rings 11 are hung through a locking band 12 that locks the shoe main body 1a including the upper, lower back, and hips.

  In this case, the size of the support 5 that covers the part of the arch 4 of the shoe sole 2 has a width equal to or greater than the width of the arch 4 of the shoe sole 2 and, as shown in FIG. A locking band 12 is hung on the upper part 1b of the shoe body 1 and the heel part 1c of the rear part of the shoe so that the support 5 is in close contact with the surface of the arch 4 of the shoe sole 2. In this case, as shown in FIG. 5, the ends of the instep band 12a of the locking band 12 and the ends of the hook band 12b are fixed by means of easy attachment / detachment such as a flat fastener 12c. .

  As shown in FIG. 1, the support 5 made of an elastic rubber material having an appropriate hardness has a thickness for supporting the arch 4 higher than the surface connecting the shoe tip sole surface 2b and the heel sole surface 2c. In this case, as shown in FIG. 2, the upper surface of the support body 5 is connected to the shoe sole 2 from the middle-high surface of the center 5c of the support body 5 so as to smoothly connect the shoe sole surface 2b and the heel sole surface 2c. The surface of the front end 5a and the rear end 5b of the support body 5 that is in contact with the lower surface of the support body 5 is lowered with a gentle inclined surface 5d, and is stably positioned on the arch 4 of the shoe sole 2 that forms a concave surface. . A ring rising piece 5f having a ring fitting groove 5h corresponding to the ring diameter of the lifting ring 11 is integrated with the width direction end portion 5e of the support body 5. This ring rising piece 5f has a notch of the ring fitting groove hole 5h into which the lifting ring 11 is fitted, and this cutting does not restrict the small movement of the support 5, but the ring fitting groove hole of the ring rising piece 5f It is firmly fixed so that the lifting ring 11 does not come off from 5h.

  The lifting ring 11 of the support 5 is made of, for example, a stainless steel rod, and has a ring diameter (for example, φ4.0 mm) that can withstand the load during walking and that protrudes downward from the grounding surface of the support 5 and does not contact the road surface 13. The ring rising piece 5f is fitted in the notch in the ring fitting groove 5h. The lifting ring 11 can be made of a functional plastic such as ABS or polyacetal in addition to the above stainless steel. By engaging with the ring fitting groove 5h of the ring rising piece 5f, the engaging portion of the lifting ring 11 has a degree of freedom to move freely. Hold to withstand wear and tear.

  On the other hand, as shown in FIG. 6, the same elasticity as that of the support body 5 from the front portion and the rear portion of the support body 5 across the groove 6 extending in the shoe width direction among the cross-shaped grooves 6 on the upper surface of the support material 5. It is also possible to form a lifting ring 11 that is integrally formed from a material and raised in a ring shape. In the case of the lifting ring 11 made of this elastic material, the ring rising piece 5f for fitting the lifting ring 11 is unnecessary because it is integrally formed with the support. The thickness of the lifting ring 11 integrally formed of the elastic material is ½ times the thickness of the center 5c of the support 5 so that the width of the lifting ring 11 can withstand the locking and fixing of the locking band 12 described below. The lifting ring 11 has a thickness that is twice or more the thickness of the lifting ring 11 and has a structure in which a corrugation 11 a is formed from the end of the support member 5 toward the upper end of the lifting ring 11. By doing in this way, the thickness of the lifting ring 11 in the portion of the support 5 where the locking band hole 11b is formed is thinner than the thickness of the center 5c of the support 5, and the thickness is corrugated 11a. The portion of the locking band hole 11b easily extends along the width of the shoe sole due to expansion and contraction, and the impact applied to the support 5 is reduced to enhance durability.

  The locking band 12 that locks to the lifting ring 11 is formed of a material such as leather, woven fabric, plastic sheet, or rubber sheet. The locking band 12 is locked to the lifting ring 11 by a method in which the locking band 12 is engaged with a flat fastener 12c provided at the end of the band 12. In this case, the upper band 12a that forms the locking band 12 is engaged with the upper part 1b of the shoe, while the upper band 12b that forms the locking band 12 is engaged with the upper part 1c of the shoe, The support 5 is detachably locked to the shoe sole 2, and the tightening of the shoe upper part 1b and the shoe rear part heel part 1c can be adjusted by the upper band 12a and the heel band 12b. The sole of the shoe sole 2 is in close contact with the lower center of the arch 4. Further, the upper band 12a and the heel band 12b of the locking band 12 are integrated into one at each end, and the lifting ring 11 is fixed to the lifting ring 11 in addition to the above-described method using the flat fastener 12c. Use a fixing method that does not give resistance. Further, instead of the engagement by the flat fastener 12c, a fixing buckle or engagement by a D-ring can be used. The function of the locking band 12 is not only to fix the support body 5 to the shoe sole, but also to place the support body 5 at an appropriate position on the arch 4 of the shoe sole 2 according to the specific shape of the foot of the user. It is to install. For this purpose, the locking band 12 is separated into an instep band 12a and a heel band 12b, and is engaged by a flat fastener 12c with adjustable band length, a fixing buckle or a D-ring.

In the means of the invention according to claim 1, the support 5 made of an elastic rubber material is used for kneading crushed powder of walnut shells or rice husks into an elastic rubber material for preventing slippage of a snow-capped road surface 13 or a frozen road surface 13 in winter. This is a walking aid 3 attached to the sole 2 of the walking shoe 1 made of a molded body. The grounding surface which is the lower surface of the support 5 is located in the middle of the shoe tip sole surface 2b and the heel sole surface 2c. Therefore, when walking, the shoe sole 2 of the forefoot that has been stepped down lands, the heel sole surface 2c, which is the rear end of the shoe sole 2 of the foot, is grounded first, and the shoe sole 2 of the rear foot that has started kicking is When leaving from 13, the shoe sole surface 2b of the foot finally leaves the road surface 13. Thus, when landing on the road surface 13 or leaving the road surface 13, the portion of the support body 5 disposed at the position of the arch 4 is. No force is applied to the ground contact with the road surface 13. Therefore, on the normal road surface 13, it is not necessary to give the support body 5 a large anti-slip performance. However, since the entire shoe sole is slippery on the road surface 13 in which snow is pressed or frozen in winter, it has excellent water absorption performance with high frictional resistance, and crushed powder of walnut shell or rice husk known as an anti-slip material on the snow surface is used. It is assumed that the support body 5 kneaded and molded into a raw rubber material is used. By providing this support body 5, the anti-slip performance at the center of the shoe sole with respect to the ground contact surface is imparted, and even if the surface of the support body 5 is worn, a new anti-slip performance surface is always exposed. The anti-slip performance against frozen surfaces is always demonstrated. The crushed powder of walnut shell or rice husk kneaded into the raw rubber material as the above-mentioned anti-slip material is kneaded and molded at a blending amount of 3 to 20 parts by mass per 100 parts by mass of the rubber polymer component.

In the means of the invention according to claim 2 , the support body 5 is made of a constant thickness made of a plurality of elastic materials, and is formed by laminating a spacer 7 whose length is shortened stepwise on the top. ing. By attaching this support body 5 to the shoe sole 2, the shoe sole 2 including the support body 5 has a shape that follows an arc 10 drawn with a radius 9 to the surface of the shoe sole 2 centered on the hip joint 8 during walking. The shape of the surface can be deformed.

  That is, the spacer 7 of the support 5 is placed and supported on the support 5 in order to keep the height position of the support 5 at a constant height in accordance with various and multi-size walking shoes 1. It is integrated with the body 5. For this purpose, the height of the spacer 7 is shorter than the length of the support 5 in the front-rear direction so that the height can be adjusted according to the shape of the dent recessed above the arch 4 of the shoe sole 2. A plurality of sheets having a short length are overlapped as appropriate, and the thickness of one spacer 7 is set to be 1/3 of the maximum thickness of the support 5, and the support 5 as described above. It is assumed to have been inserted between the top of the shoe and the arch of the sole. In this case, fixing to the support 5 is performed by providing notch grooves 7b that fit into the inner diameter of the lifting ring 11 of the support 5 at both ends of the end portions 7a of the spacers 7 in the width direction. The lifting ring 11 is detachably inserted and fixed to be integrated.

  As shown in FIG. 1, the support 5 is in close contact with the arch 4 of the shoe sole 2 by the load of the body during walking and the tightening force of the locking band 12. Therefore, the upper surface of the support body 5, which is the surface opposite to the ground contact surface, is formed on the arch 4 as shown in FIG. 2 so as to easily follow the shape of the arch 4 of the shoe sole 2 that forms a recess with respect to the road surface 13. The groove shoulder portion of the groove 6 having a width of 20 mm extending in the direction of the left and right lifting rings 11 is formed at the apex portion of the inside and outside thickness of 6 mm, and the shoe tip sole surface 2b side of the shoe bottom surface 2a is formed. A gentle inclined surface 5d is formed on the heel sole surface 2c side, and the thickness is gradually reduced so that the front end 5a and rear end 5b portions of the support 5 are reduced to a thickness of 2 mm inside or outside. By using the inclined surface 5 as described above, the support 5 and the spacer 7 follow the shape of the arch 4 of the shoe sole 2 by the reaction force of the load from the ground during the exercise, and from the shoe tip sole surface 2b of the shoe bottom 2a. A predetermined continuous arc 10 is formed between the heel sole surface 2c.

  As shown in FIG. 6, the thickness of one spacer 7 is set to be 1/3 of the thickness of the support 5 that is normally required from the shoe bottom surface 2 a, and the width of the spacer 7 is the same as the width of the support 5. And However, the length of the spacer 7 in the longitudinal direction of the shoe is shorter than the support 5 in a stepwise manner, and the spacer is composed of a plurality of necessary numbers according to the concave shape formed on the arch 4 of the shoe sole 2 during walking. 7 is laminated on the upper layer so that it gradually shortens, and the centers of the front and rear of each spacer 7 are matched to form a pyramid shape, thereby matching the concave shape formed on the arch 4 of the shoe sole 2 during walking. The thickness.

In the means of the invention according to claim 3 , the support body 5 is formed of an elastic material having a hardness capable of reliably transmitting the load reaction force received from the road surface 13 during walking to the sole. However, the sole of the foot when walking is called “tilting walking”, where the load on the body is called from the rear edge of the heel sole surface 2c to the outer edge on the little finger side of the arch 4 and from the little finger base of the shoe tip sole surface 2c to the base of the thumb. It moves with a lot of changes that move continuously to the front part of the shoe sole. For this reason, the support body 5 must also have flexibility by elasticity that can bend following the movement of each part of the shoe bottom surface 2a while maintaining the hardness. Therefore, the inscribed surface with the shoe bottom surface 2a which is the upper surface of the support body 5 has a width corresponding to 2 to 4 times the thickness of the support body 5 as shown in FIG. A cross-shaped groove 6 having a depth that is ½ of the thickness of the body 5 is formed by carving in the width direction and the length direction from the center 5 c of the support body 5. The support 5 can be bent by the cross-shaped groove 6 to make the upper surface of the support 5 concave. A bending groove 5g is formed at the center of the upper surface of the ring rising piece 5f so that the ring rising piece 5f integrated with the supporting body 5 can be bent in the same direction according to the bending of the support 5. Yes.

In the means of the invention according to claim 4, as shown in FIG. 4, a plurality of small grooves 6 a in the groove width direction are formed on the groove bottom surfaces of the grooves 6 in the width direction and the length direction forming the cross-shaped grooves 6. Are formed in an interdigital shape at an appropriate interval in the longitudinal direction of each cross-shaped groove 6. When the support 5 divided into four by the cross-shaped groove 6 is bent by the movement of the shoe sole 2, the support 5 is further bent and moved more freely by a plurality of small groove holes 6a that open in an interdigital manner. By the plurality of small grooves 6a formed in the shape of the interdigital, the load reaction force from the road surface 13 that tends to concentrate on the center 5c of the arch 4 of the shoe sole 2 is distributed over the entire area of the arch 4 so that the shoe sole 2a can be freely used during walking. It is assumed that the hardness and elasticity of the support 5 that do not hinder proper movement are realized.

  In the present invention, the thickness shape in which the center 5c of the support body 5 is thickened, the front end 5a and the rear end 5b are thinned, and the upper surface of the support body is the inclined surface 5d facilitates weight movement during walking by the shape, It achieves the two purposes of realizing comfortable walking and increasing the pressure effect of the arch 4 of the shoe sole 2 and activating the circulation of the venous flow of the foot. As described above, the support body 5 having a middle height of about 6 mm at the center 5c applies only the support body 5 without the spacer 7 to the shoe sole 2 without the arch 4 on the shoe bottom surface 2a. . On the other hand, for the shoe bottom surface 2 a provided with the arch 4, a spacer is provided on the upper surface of the support 5 in order to increase the thickness of the support 5 so as to compensate for the gap 4 a generated between the shoe bottom 2 a and the support 5. It is assumed that an appropriate number of sheets 7 are stacked to create a certain medium-high shape on the arch 4 of the shoe bottom surface 2a. Thus, by creating a middle-high shape on the arch 4, it is possible to realize an ideal walking body shape in various walking shoes 1 for walking. The ideal walking body shape in this walking indicates the locus of the shoe bottom surface 2a having the shape of the arc 10 described above.

  The ideal walking figure for this walking is the posture with no distortion, walking with the knee 8a stretched, moving the center of gravity like rolling to roll the sole, walking with speed, etc. Of 1/2 of this. However, the middle-high shape of the center 5c of the support 5 is an ideal walking body shape. Two points of walking where the knee 8a is extended and walking where the center of gravity moves like rolling which rolls the sole are shown in FIG. Furthermore, it supplements the necessary movement of each body part that occurs during walking. That is, walking with the knee 8a extended means that the locus of the shoe sole 2 of the body inevitably draws a circular arc 10 having a radius 9 from the heel sole surface 2c, which is the landing point, to the hip joint 8. It will be. For example, in the upright leg at the center shown in FIG. 7, the sole 2 is on a circle indicated by a solid line, and in this case, the position of the hip joint 8 that is the center of the arc drawn by the locus of the sole 2 is the uppermost position. In the position. In this manner, the arc 10 having a radius 9 from the hip joint 8 to the heel sole surface 2c while reaching the shoe sole surface 2b in front of the arch 4 which is the separation point from the heel sole surface 2c which is the landing point. By creating the shape on the shoe bottom surface 2a by the support body 5, the hip joint 8 is moved up and down by the vertical movement width 8b. That is, in a state where the front foot is forward and the rear foot is backward, the position of the hip joint 8 is in a position lowered by the vertical movement width 8b, and the circle centering on the hip joint 8 in this lowered position is shown in FIG. This is indicated by a dotted line. In this way, while the hip joint 8 is moved up and down, the shoe bottom surface 2a follows an arc shape that effectively moves up and down during walking. Furthermore, the shape of the shoe bottom 2a is formed from the bottom surface of the support 5 and the smooth continuous arc 10 because the center of gravity is moved so as to roll the shoe sole 2 by creating the above-mentioned middle-high shape on the support 5. Become a shape. By forming the support body 5 in this way, the movement of the center of gravity of the body during walking follows the shape of the arc 10 formed by the shoe bottom surface 2a, and the walking point with the knee 8a extended and the shoe sole 2 In addition to the two points of the point of contact with the road surface 13 so as to roll and move the center of gravity, the other points of walking, that is, the point of undistorted posture and the point of walking with a large stride can be realized. A more comfortable walking can be realized by applying the support body 5 having an appropriately set shape having a medium-high thickness to the arch 4 of the shoe sole 2.

  By the way, in the walking shoe 1 shown in FIG. 8 (a) in which the arch 4 is not formed on the shoe sole 2, the support 5 constituted by a flat slope in the front-rear direction is joined to the shoe bottom 2a. When it is arranged on the lower surface of the arch position of the foot of the bottom surface 2a, as to whether the grounding surface side of the support 5 draws the above ideal arc 10 or not, the grounding surface side of the support 5 is exceptionally circular. As shown in FIG. 8 (b), as a result of walking with the walking shoes 1 even if the walking shoes 1 are not placed in the shape, the heels behind the rear end 5c of the support body 5 are formed into a shape suitable for natural walking. The shoe bottom surface 2a extending from the sole surface 2c to the shoe tip sole surface 2b in front of the front end 5a of the support 5 is deformed so as to draw a gentle arc 10 shown in FIG. And the cross-sectional shape of the groove | channel 6 extended in the shoe width direction is expanded-contracted so that the groove width may match | combine with a circular arc, as shown to (a) to (b) of FIG. At this time, the upper surface of the support body 5 forms the shape of the arch 4 on the shoe bottom surface 2a by material elasticity, and the thickness 5i of the support body 5 is formed on the arch portion of the shoe bottom surface 2a. As a result, the shoe bottom surface 2a can easily realize the gentle arc 10 shown in FIG.

  On the other hand, as shown in FIG. 9 (a), in the walking shoe 1 in which the arch 4 is formed on the shoe sole 2, as described above, in order to adjust the height of the arch 4 portion, A plurality of spacers 7 having different lengths that are shorter as they become higher are placed on top of each other. However, in this case, as shown in FIG. 9 (b), by inserting the spacer 7 onto the support 5, the portions of the front end 5a and rear end 5b of the support 5 at the arch 4 portion of the shoe sole 2 are obtained. It is not necessary to eliminate all the gaps 4a between the road surface 13 and the road surface 13. The front edge 7c and the rear edge 7d of the spacer 7 abut against the shoe sole 2 between the front end 5a and the rear end 5b of the support body 5, so that the support body 5 is the front and rear portions of the arch 4 and Bending upward with a gap between the bottom surface 2a and the gap 4a, a bridge 5 is formed, and a thickness 5i is formed between the road surface 13 and the arch 4 portion of the shoe sole on the upper surface of the support 5 including the spacer 7. As a result, the shoe bottom surface 2 a having the arch 4 forms a gentle arc 10 shown in FIG. 7, and the cross-sectional shape of the groove 6 extending in the shoe width direction is also expanded and deformed. If this action is utilized, the length of the spacer 7 in the front-rear direction is gradually shortened from the length of the support 5 in the front-rear direction, and a plurality of spacers 7 having the same thickness are aligned and held. By selecting the length of the spacer 7 in the front-rear direction and the number of stacked sheets for all target shoe types, the walking shoe 1 having various heights of the arches 4 can be handled.

  The support 5 has a front end 5a and a rear end 5b covering the arch 4 having an inner and outer length of 70 millimeters, and a slope from a flat middle and high thickness portion of the center 5c of the support 5 which is the center of the cross-shaped groove 6. Thus, it is shaped so as to follow the arch 5 of the shoe sole 2 by lowering to the front end 5a and the rear end 5b. Therefore, the support body 5 applies a pressing force to the arch 4 of the shoe sole 2 with a deformation amount corresponding to the thickness of the support body 5 at every walking. In the case of a normal shoe sole 2, the pressing force to the arch 4 is painful because it has a strength exceeding the weight due to the road surface reaction force against the load caused by walking. However, in the present invention, the inclined surface of the support 5 is provided not on the grounding side of the support 5 but on the upper surface, which is a joint surface with the shoe bottom 2a, so that it easily comes into contact with the deformable shoe bottom 2a. And the load is distributed. Further, since the support body 5 is vertically and horizontally divided into four by the cross-shaped grooves 6 in the width direction and the length direction of the center 5c of the support body 5, the support body 5 flexibly contacts the shoe bottom surface 2a by bending. Thus, the load reaction force on the shoe bottom surface 2a is not concentrated and transmitted, and acts as a moderately dispersed compression force on the support body 5. The effect of applying pressure distributed to the arch 4 while continuously moving from the rear end 5b of the support 5 to the front end 5a for each step of walking gathers on the arch of the foot of the human body as shown in FIG. The pressure applied to the venous plexus 14a is changed. This venous blood flow in the foot is called the second heart, and the pressure on the venous plexus and the great saphenous vein 14 is generated by stretching and contracting the foot muscles and compressing the foot arteries, and the blood flows into the heart. It is already known that one of the reasons why refluxing is performed and walking is recommended for maintaining health is this return of venous blood flow. However, it is also known that since the foot is farthest from the heart, it is difficult for blood flow to circulate and easily cause swelling. Exercise by the walking shoe 1 equipped with the support 5 having the shape of the present invention can continue to send moderate pressure with movement accompanying weight shift to the arch venous plexus 14a without causing pain. By the way, from the viewpoint of physiology, the phenomenon of activation of blood flow to the distal end of the whole body by stimulation of the large saphenous vein 14 of the lower limb and the arch venous plexus 14a in walking is known.

  The support body 5 is made of an elastic material such as natural rubber, synthetic rubber, urethane rubber, and is filled with an inorganic or organic filler according to the application, but reliably transmits the weight reaction force from the road surface 13 to the shoe bottom surface 2a. Therefore, it is made of a highly elastic material having hardness while following the unevenness of the road surface 13. However, when such a highly elastic material is used as a plate member for the support member 5 to be attached to the sole, the support member 5 functions as a single rigid body because of the high elasticity of the plate member. It restrains the free movement of the sole of the time, resulting in pain during walking on the knees, ankles, insteps, and groin. In order to avoid such drawbacks and use a highly elastic material for the support 5, a means for making the entire material flexible while taking advantage of the partial hardness of the material is adopted. Therefore, in order to remove pain from the arch, the above-described cross-shaped groove in the center 5c of the joint surface of the support 5 with the shoe sole 2 has a depth of ½ of the maximum thickness of the support 5. 6 is formed as described above to form a cross-shaped groove 6 that divides the plate surface of the support 5 into four. Further, as shown in FIG. 4, a plurality of small groove holes 6a in the groove width direction are opened at an equal interval at the bottom of the cross-shaped groove 6 as appropriate. While the plate material that is the support 5 is divided into four blocks having hardness by the mechanism of the cross-shaped groove 6, the support 5 as a whole is affected by changes in the road surface 13 and changes in load movement of the shoe sole 2. It is a material that can bend flexibly and flexibly. The most natural walking is the “tilting walking” as described above, and the tilting walking motion is smooth using all of the front, back, left and right of the sole while moving up and down the hip joint 8 as shown in FIG. Because it is an exercise, if there is a movement that restrains the smooth weight transfer movement during one step, each part of the foot will feel defective, and the hip joint, knee, ankle, instep, foot, and toe Pain at the base. The support body 5 must have a hardness that supports weight, and at the same time, must be flexible so as not to interfere with the movement of the soles. Therefore, the support body 5 has a shape that can be flexibly deformed while forming a support body with a highly elastic material. take.

  Next, the above-described anti-slip property of the support 5 will be further described. The height, which is the thickness of the support 5 for adults, is 6 mm inside and outside at the maximum thickness portion of the center 5 c, but the thickness of the front end and the rear end of the support 5 is 2 mm inside and outside, so this support 5 When walking with the aid 3 having the walking foot 1 attached to the walking shoe 1, the shoe sole 2 is easily deformed at the arch 4, and when standing upright, the shoe 5 is worn by the load of the body with the support 5 attached. The heel and sole of the bottom 2 have a level of hardness and step back that can be landed simultaneously. In this landing state, the support body 5 placed in the center of the sole is stable and there is no possibility of causing slippage alone. The slipping of the shoe sole 2 during walking often depends on the frictional force on the road surface 13 of the heel corner and the sole when landing and kicking. Therefore, in this respect, the support 5 is not directly related to the landing and kicking of the foot, which tends to lose balance. The support body 5 acting as a fulcrum at the center of the body does not need strong anti-slip properties on the normal road surface 13. However, on the slippery road surface 13 or the frozen road surface 13 due to snow pressure in winter, anti-slip properties are required for the support that shares weight at the center of the body. That is, as described in paragraph 0023, applying a frictional force to the support body 5 acting at the center of the shoe sole 2 has an anti-slip performance that makes it easy to balance the weight on the slippery road surface 13.
