Description

  The present invention relates to an insole that can stably transmit the force of a toe to a shoe sole, and a shoe equipped with the insole.

  As an insole for stably transmitting the force of the toes to the shoe sole, an insole main body and a crotch bridge that is detachably attached to the insole main body have been proposed (for example, patent document) 1). This crotch bridge includes a sole base portion, a back cover portion, a crotch bridge portion connecting the sole base portion and the back cover portion, and a slit portion at the front end portion of the insole body. The crotch bridge portion of the crotch bridge is inserted into the slit portion of the insole body.

  In this insole, the crotch bridge portion of the crotch bridge is located between the first and second heels of the toes, and the crotch bridge portion is sandwiched between the first and second heels. Therefore, the instantaneous force of the toe can be transmitted to the toe bottom of the shoe without loss, and the athletic ability can be improved.

Japanese Patent No. 5806427

  However, in the conventional insole, since the toe bridge is a configuration that is detachably inserted into the slit part of the insole body, when a large force is applied to the toe bridge when walking downhill or on a bumpy road, The crotch bridge is easy to move relative to the insole body, and the force of the toes cannot be reliably transmitted to the bottom of the toe of the shoe through the crotch bridge and the insole body. In particular, when the insole is housed in the inner sole of the shoe, the sole base portion of the toe bridge is held in contact with the inner bottom of the shoe, and the upper cover portion is held in contact with the inner surface of the upper portion of the shoe. Therefore, there is a problem that it is difficult to reliably hold the crotch bridge by the crotch.

  Moreover, in this groin bridge, the groin bridge portion is located at the groin between the first heel and the second heel. Since the groin bridge portion is provided in a wall shape, There is a problem that it is difficult to grasp the groin bridge portion by the second heel, and accordingly, it is difficult to apply force to the toes of the foot including the first heel.

  In addition, when wearing a conventional insole in a state of being accommodated in shoes, the position of the crotch bridge is unstable and difficult to wear, and it is difficult to securely hold the crotch bridge on the crotch while walking. There is a problem.

  The present invention solves the above-mentioned problems, can stably transmit the force of the toes to the sole, can increase the muscle strength of the toes, and is easy to wear in the state of being accommodated in the shoes. And it aims at providing the shoes provided with this.

In order to solve the above problems, the present invention provides an insole body that can be accommodated in the inner bottom of a shoe,
One end portion is detachably attached to the toe side front portion of the insole body, and the front grammage is provided with an instep support member on the other end portion, and
The upper side support member extends to the toe side starting from the front tsubo and extends long to the heel side starting from the front tsubo, and extends from the center of the portion in contact with the front tsubo to the toe side tip. When SL is SL and the length from the center of the portion in contact with the front tsubo to the heel side end is KL, SL ≦ KL and the inner surface of the upper end of the shoe tip can be contacted. A toe side tip,
The toe-side end portion of the back side supporting member is to provide a insole which is characterized not to contact with the toe side front portion of the insole body.

  With this configuration, the force of the toes can be stably transmitted to the shoe sole, and the muscle strength of the toes can be increased, so that the toes can be easily worn while being accommodated in the shoes.

  That is, when the upper side support member extends in the front-rear direction from the toe side to the heel side with respect to the front tsubo, it comes into contact with the inner surface of the upper part of the upper part of the shoe, particularly at the heel side from the front tsubo and rubs. It is possible to prevent the tip of the toe side from coming into contact with the inner surface in the tip direction of the shoe by extending it to the toe side of the instep support member. The integrity of the can be improved.

Further, the upper side support member has SL as the length from the center of the portion in contact with the front tsubo to the toe side tip, and the length from the center of the portion in contact with the front tsubo to the heel side end. When it was set as the relationship that SL ≦ KL, it will take a large area from the portion in contact with the front tsubo to the heel side end, and securely contact the inner surface of the upper part of the shoe It is possible to prevent movement due to friction. Further, since the front tsubo is detachably attached to the insole body, the position of the front tsubo can be adjusted according to the length of the individual foot, and the upper support member can be easily replaced. Moreover, it is more preferable that the front tsubo and the upper support member are detachably attached. Thereby, while being able to adjust the length to the toe side or the heel side starting from the front tsubo , the upper side support member, the front tsubo, and the insole body can be easily replaced.
In addition, the toe side tip of the instep support member is not in contact with the toe side tip of the insole body, so that a gap is provided between the toe and the shoe inner surface so that the toe The contact with the inner surface of the support member can be prevented to avoid toe damage and fatigue.

  And if you put on your shoes with the insole on the inner bottom of the shoe, the front tsubo is located on the crotch between the first and second heels of the toes. As a result, the weight shift when walking is linearly moved from the heel to the first heel, and as a result, the force of the toes is stably transmitted to the sole and walking, running, etc. Can be stabilized. Further, in this walking and running state, the front tsubo acts on the crotch between the first heel and the second heel, and when the force is applied to the toes, the first tsubo and the second heel are grasped. As a result, force is applied to the toes of the toes and the tension becomes stronger. This also stabilizes walking, running, etc., and can increase the strength of the toes, providing an insole and shoes excellent for the toes. Further, walking and running with force applied to the toes of the toes can stabilize the posture and prevent back pain and knee pain.

The front grab has a columnar member, and one end of the columnar member may be detachably attached to the insole body, and the other end may be detachably attached to the upper support member. .

Thereby, it can be set as the firm front square. Preferably, the insole body may be attached to the columnar member with a screw or a press-fitting member. Thereby, since attachment and detachment of the front tsubo becomes easy , the front tsubo, the insole body, and the upper side support member can be easily replaced.

  The front floor may be configured to include an elastic sleeve that covers the columnar member.

  With this configuration, the elastic sleeve comes into contact with the first and second heels of the toes and the groin between them while securing sufficient rigidity and strength by the columnar member at the center of the front tsubo. Even if configured in this manner, it can be an insole that is gentle on the legs but strong on the crotch.

A front tsubo position adjustment unit is provided at a toe side front portion of the insole body, and the front tsubo is detachably attached to the insole body through the front tsubo position adjustment unit, thereby adjusting an attachment position of the front tsubo. It may be configured to be adjustable.

  With this configuration, the front tsubo can be attached by the front tsubo position adjustment unit so that the position can be freely adjusted, and the insole body is adjusted by adjusting the position of the front tsubo according to the length from the heel to the base of the first and second ridges. Can be attached to. In short, if the length from the base of the toes to the bases of the first and second toes of the toes is adjusted according to the individual's feet, the shoes from the bases of the first and second toes of the toes Even if the length up to the tip is slightly longer, the foot can be firmly held, so even shoes that are slightly longer in the front-rear direction can be selected with emphasis on shape. In addition, since there is a margin between the toes and the tip of the shoe, it is possible to move the toes and prevent blood circulation problems. The front tsubo position adjustment unit can be configured by an insertion slit or an insertion opening (hole).

The mounting position of the front tsubo by the front tsubo position adjustment unit is such that the length ML from the rear end portion of the front tsubo to the heel side end portion at the toe side front portion of the insole body is the heel rear end portion of the foot. Position for right foot and left foot based on the length of right foot and left foot of each person so that it is almost the same as the length AL from the first to the base of the toes to the base of the first toe It is good also as a structure which can adjust each .

  With this configuration, it is possible to create an insole that fits the individual's feet. Even if you walk in the downhill with the shoe stored in the shoe, the crotch is fixed to the front floor of the insole, and the toes are at the tip of the shoe. It can be an insole that is gentle on the feet without touching the inner surface and causing pain.

  It is good also as a structure which has the holding part which can be hold | gripped with a finger | toe when putting on the shoes which accommodated the said insole in the heel side edge part of the said back side support member.

  With this configuration, when a shoe containing the insole is worn, the gripping portion can be easily worn without bending the waist even if there is no shoe spatula by gripping and pulling the gripping portion with fingers. The position of can be prevented from shifting to the shoe tip side. Moreover, even if the position of the front tsubo shifts during walking, the position of the front tsubo can be returned to the crotch between the first welfare and the second welfare by gripping and pulling the grip portion with fingers.

  It is good also as a structure which has the exposed part exposed outside from the wearer's shoe mouth in the heel side edge part among the said holding parts in the state accommodated in the said inner bottom of the said shoes.

  With this configuration, when wearing a shoe containing the insole, the exposed portion can be easily grasped with fingers and pulled easily, and even without a shoe vera, it can be easily worn without bending the waist. It is also possible to avoid shifting the position toward the shoe tip side.

  It is good also as a structure by which coloring, a character, or a brand name is drawn on the outer surface or inner surface of the said exposed part.

  With this configuration, it is possible to provide an exposed portion with excellent design, and it is possible to provide pleasure to wear shoes that accommodate the insole.

  In the region from the portion in contact with the front tsubo of the upper side support member to the heel side end portion, at least an outer surface of the upper side support member is provided with a holding reinforcement portion that reinforces the holding on the upper portion of the shoe. In the state accommodated in the inner bottom of the shoe, the outer surface of the holding reinforcement portion may be configured to contact the upper portion of the shoe.

  With this configuration, in the state in which the insole is accommodated in the inner bottom of the shoe, the holding reinforcement portion in the heel side region of the upper side support member and the inner surface of the upper portion of the upper portion of the shoe are contacted and held, so that the upper side support member The movement of the shoe toward the tip side of the shoe can be reliably suppressed, and the front tsubo can be reliably held at a predetermined site between the insole and the upper side support member. The holding strengthening part can be constituted by a hook-and-loop fastener or the like.

  It is good also as a structure which provided the thin part which makes thickness of the said insole main body thin in the area | region of the front-end | tip direction rather than the part which supports the toes in the toe side front part of the said insole main body.

  With this structure, the part where the toes touch the insole when climbing a mountain path or stairs becomes thin, making it easier to step on the toes, reducing the burden on the heel side and preventing back pain and knee pain Can increase toe strength.

  In the insole body, a region corresponding to the thin portion may be cut.

  With this configuration, the toes can be easily stepped on with a simple configuration, the burden on the heel side can be reduced, lower back pain and knee pain can be prevented, and the strength of the toes can be increased.

  It is good also as a structure which attached the adjustment part between the said insole main body and the said back side support member separately from the said front tsubo.

  With this configuration, even when the body is pushed from the left and right, a force can be applied to the toe and the sole of the foot to be stretched. Further, by adjusting the position, the hallux valgus for each person can be corrected.

  It is good also as a structure which accommodated one of said insoles in the inner bottom of a shoe main body.

  With this configuration, the force of the toes can be stably transmitted to the shoe sole, and the muscle strength of the toes can be increased.

When the shoe with the insole provided with the front tsubos position adjustment part is accommodated in the inner bottom of the shoe, the toes do not come into contact with the inner surface of the toe side tip portion of the shoe due to a gap. In addition, the front tsubo may be attached to the insole body at a position adjusted by the front tsubo position adjustment unit.

  With this configuration, when the shoe is worn, the tip of the toe is adjusted so that the toes do not come into contact with the inner surface of the tip of the toe side of the shoe. This eliminates the damage and fatigue of the toes. In addition, this can improve the toe strength.

  The insole of the present invention and a shoe equipped with the insole can stably transmit the force of the toes to the sole, increase the strength of the toes, and are easy to wear in the state of being accommodated in the shoes. And a shoe equipped with the same.

It is a figure explaining the length measurement of the foot in Example 1 of this invention, (a) shows the sole of a right foot, (b) shows the sole of a right foot.

  A first embodiment of an insole according to the present invention will be described with reference to FIGS.

  1 to 5, the illustrated insole 2 includes an insole body 4 corresponding to the shape of the inner surface (that is, the inner bottom 106) (see FIG. 7) of the bottom 104 of the shoe 102, and the toes of the insole body 4 The side front part 6 is formed flat, the center part 10 in the width direction at the heel side rear part 8 is formed flat, the both side parts 12 in the width direction are curved upward and the inner side surfaces of the both side parts 12 are outside. Inclined upward toward the direction. Therefore, in the insole body 4, the back surface of the foot 108 is positioned in a flat portion of the insole body 4 (that is, the center part 10 in the width direction of the toe side front part 6 and the heel side rear part 8). The side portions 12 in the width direction wrap the heel side of the foot 108 from both sides, so that the shoe can be accommodated in the shoe 102 and has a shape corresponding to the foot.

  In addition, in Example 1, although it was set as the structure provided with the heel side rear part 8, it is not necessarily limited to this but can change suitably. For example, it is good also as the insole body 4 which shortened the length from the toe side front end which has only the toe side front part 6. FIG.

  The insole body 4 can be formed of, for example, a synthetic resin material having flexibility, and the surface thereof may be covered with a woven fabric or the like. Further, the insole body 4 may be a substantially flat one as a whole.

  In the insole 2, a front grab 14 is attached to the toe side front portion 6 of the insole body 4, and an instep support member 16 is attached to the upper end of the front grab 14. The length of the front tsubo 14 is arbitrary, but it is desirable that the height of the front sill 14 is such that the toes can be brought into contact with the inner surface of the upper part 112 of the shoe without pressing the toes when the insole is accommodated in the shoe. . Referring also to FIG. 6, the front grammage 14 includes a cylindrical hollow sleeve 18 as a flexible hollow sleeve, and a pair of core cords 20, 22 disposed through the cylindrical hollow sleeve 18. The cylindrical hollow sleeve 18 can be made of, for example, a synthetic resin material, and the pair of core cords 20 and 22 can be made of, for example, a cloth-like string. In addition, you may make it use what put together a pair of core ropes 20 and 22, and may make this cylindrical hollow sleeve 18 abbreviate | omit.

  1 and 2, the front tsubo 14 is described so as to stand upright on the insole body 4. However, the front tsubo 4 does not necessarily stand upright, and the front tsubo 4 is inclined toward the heel side or the toe side. It may be attached to the insole body 4.

  In the first embodiment, one end (the lower end, that is, the end portion on the insole main body 4 side) of the cylindrical hollow sleeve 18 is disposed so as to contact the surface of the toe side front portion 6 of the insole main body 4 and the other end ( The upper end, that is, the end portion on the upper support member 16 side) is disposed so as to contact the inner surface of the upper support member 16, and one end side of the pair of core cords 20 and 22 is one end side of the cylindrical hollow sleeve 18. Are attached to the insole body 4 and the other end thereof is attached to the upper support member 16 through the other end side of the cylindrical hollow sleeve 18, thereby being supported between the insole body 4 and the upper support member 16. .

  In the first embodiment, for example, one end side of the pair of core cords 20 and 22 is protruded to the back side through an insertion slit 24 as a front grammage position adjusting portion formed in the insole body 4 and is shown by a broken line in FIG. In addition, the one end portion thereof is expanded and fixed to the outer surface of the insole main body 4 with an adhesive or the like, thereby being attached to the insole main body 4. Although the other end sides of the pair of core cords 20 and 22 are not shown, for example, by expanding the other end portions and fixing them to the inner surface of the upper side support member 16 with an adhesive or the like. It is attached to the side support member 16. The insertion slit 24 extends in a direction connecting the toe side and the heel side of the insole body 4, and therefore, the position of the front grammage 14 can be adjusted in this direction.

  In the first embodiment, since the pair of core cords 20 and 22 are attached through the insertion slit 24 as the front grammage position adjusting portion provided in the insole body 4, in a state before the pair of core cords 20 and 22 are fixed. These core cords 20 and 22 can be moved along the insertion slit 24 in the front-rear direction of the insole body 4 (left-right direction in FIG. 7). The mounting position can be adjusted.

  For example, when going down stairs or down a mountain path, the toes are usually pressed against the inner surface of the tip side of the toe side of the shoe and may be stressed. As a result, the toes may be damaged or the entire body may become tired. Therefore, when the shoe is worn, the position of the front grammage 14 can be set using the insertion slit 24 at a position where the toe does not contact the inner surface of the toe side tip portion of the shoe.

  A specific method for setting the position of the front square 14 will be described. A person has different lengths on the left and right legs. Accordingly, the position of the front square 14 is set by measuring the length of each person's left and right. FIG. 11A shows the sole of the right foot, and FIG. 11B shows the sole of the left foot. Measure the length AL from the rear edge of the heel to the base of the first and second limbs of the toes. This length AL is RAL for the right foot and LAL for the left foot.

  Then, the insertion slit 24 is set so that the length ML from the heel side end portion of the insole body 4 shown in FIG. 3 to the rear end portion of the front floor 14 at the toe side front portion 6 of the insole body 4 becomes ML = RAL. Is used to set the position of the front foot 14 for the right foot, and the position of the front foot 14 for the left foot is set using the insertion slit 24 so that ML = LAL.

  It should be noted that either the right foot length RAL or the left foot length LAL or the average value is used as a common length AL so that both the right foot and the left foot ML = AL. The position of the tsubo 14 may be set. In this case, the length ML of the insole body 4 from the rear end portion of the front tsubo 14 to the heel side end portion at the toe side front portion 6 is the first heel and second heel of the toe from the heel rear end portion of the foot. It is almost the same as the length AL to the root.

  In the first embodiment, the position of the front grammage 14 is set using the insertion slit 24 as the front grammage position adjustment unit, but the present invention is not necessarily limited to this and can be changed as appropriate. For example, instead of providing the insertion slit 24 in the insole main body 4, the front gravel 14 may be attached by providing an insertion opening as a front grammage position adjusting portion at the position of the length RAL, LAL, or AL described above.

  In other words, in the first embodiment, one end (lower end) of the cylindrical hollow sleeve 18 having the front square 14 is brought into contact with the surface of the insole body 4, but instead of such a configuration, the toe side of the insole body 4 is used. An insertion opening is provided in the front portion 6 (in this case, the slit 24 is omitted). One end of the cylindrical hollow sleeve 18 is positioned in the insertion opening and attached with an adhesive or the like, and the cylindrical shape in the insertion opening is provided. One end side of the pair of core cords 20 and 22 may be protruded from the back side of the insole body 4 through one end side of the hollow sleeve 18 and attached as described above.

  Moreover, in Example 1, although the other end (upper end) of the cylindrical hollow sleeve 18 of the front grammage 14 is made to contact | abut to the inner surface of the upper side support member 16, it replaces with such a structure and the front gravel 14 of Similar to the lower end side, an opening is provided in the upper support member 16, the other end of the cylindrical hollow sleeve 18 is positioned in the insertion opening and attached with an adhesive or the like, and the cylindrical hollow in the insertion opening is provided. The other end side of the pair of core cables 20 and 22 may be projected to the outer surface side of the upper support member 16 through the other end side of the sleeve 18 and attached as described above.

  In addition, a plurality of insertion openings may be provided in the insole body 4 as the front tsubos position adjustment unit so that the attachment position of the front tsubos 14 can be adjusted.

  Furthermore, you may attach another member which has the structure similar to a front tsubos other than the front tsubos 14 with the insertion slit 24 or several insertion opening. Thereby, the force which grasps several front tsubo 14 with the 1st welfare of a toe and the 2nd welfare increases, and the tension force improves. Moreover, the said another member may be plural.

  In the first embodiment, the cylindrical hollow sleeve 18 has a cylindrical shape, but is not necessarily limited thereto, and can be changed as appropriate. For example, it may be a polygonal prism such as a triangular prism. As a result, the hollow sleeve can be more securely held on the crotch. Further, the hollow sleeve is not necessarily required, and a configuration without the hollow sleeve may be employed.

  Further, the upper side support member 16 can be made of, for example, a synthetic resin material, and the front grammage 14 is provided on the center line in the width direction perpendicular to the front-rear direction from the toe side to the heel side with respect to the front grammage 14. It is symmetrical in the width direction with respect to the center line, and the width W (see FIG. 3) of the toe side tip is configured to be larger than the width of the first and second toes of the toes. The width becomes narrower toward the heel side end, and the width W ′ at the heel side end is narrower than W (that is, W> W ′). This is because consideration is given to convenience when wearing or after wearing, such as ease of pulling when gripping portion H described later is pulled with fingers, adjustment after wearing, and the like.

  However, the width of the upper support member 16 can be changed without being limited to this embodiment. For example, W = W ′ and the same width may be the same from the toe side to the heel side, or W <W ′ and the width may be increased toward the heel side end. Moreover, it does not need to be symmetrical in the width direction with respect to the center line in the width direction orthogonal to the front-rear direction from the toe side to the heel side, and may be shaped to spread to one side.

  Further, the upper support member 16 extends long in the front-rear direction from the toe side to the heel side with respect to the front tsubo 14, and in the front-rear direction, from the center of the portion in contact with the front tsubo 14 to the tip side on the toe side When the length is SL and the length from the center of the portion in contact with the front floor 14 to the heel side end portion is KL, the relationship is SL ≦ KL. By extending to the heel side for a long time, the area from the part in contact with the front tsubo to the heel side edge will be enlarged, and it will surely prevent contact with the inner surface of the upper part of the shoe and moving by friction. be able to. In addition, as will be described later, the gripping portion H and the exposed portion R can be provided, and convenience can be provided when wearing shoes containing the insole 2. In addition, preferably, the distal end portion of the upper side support member 16 is extended to the distal end portion 110 of the shoe 102 as shown in FIG. It becomes easy to contact | abut to the inner surface of this, and the movement to the front end side of the shoe 102 of the instep side supporting member 16 can be suppressed reliably.

  Here, the instep side support member 16 extends long in the front-rear direction from the toe side to the heel side, and the instep side support member 16 simply has a length for supporting the front grammage 14. Instead, it means that it extends long from at least the front tsubo 14 toward the heel side and extends to a length sufficient to contact the inner surface of the upper portion of the shoe 102 and prevent the front tsubo 14 from falling down. Moreover, it is preferably extended from the front tsubo to the toe side. As a result, the toe side tip of the upper support member 16 can abut against the inner surface of the shoe 102 to prevent the front floor 14 from falling.

  In Example 1, the heel side end of the upper support member 16 is provided with a gripping portion H (shaded portion in FIGS. 1 and 3) as shown in FIGS. The gripping portion H refers to an outer surface (a surface opposite to a surface that abuts on the foot), an inner surface (a surface that abuts on the foot), and a side surface of the heel side end of the upper support member 16. Furthermore, the exposed part R is provided in the more edge side part of the holding parts H. The exposed portion R refers to portions of the outer surface, the inner surface, and the side surface that are exposed to the outside from the mouth of the shoe 102 when the shoe 102 is worn among the outer surface, the inner surface, and the side surface of the grip portion H. When the shoe 102 containing the insole 2 is put on, the insole 2 is not displaced forward by grasping and pulling the gripping portion H, preferably the exposed portion R, with a finger. Can be worn easily without bending your waist. As a result, the convenience of wearing can be improved, and the design of the shoe 102 can be improved by drawing red or blue coloring, a character, or a brand name on the outer surface of the exposed portion R. In addition, the inner surface of the exposed portion R may be colored, decorated with characters, brand name, or the like, and may be worn with the exposed portion R facing outward by folding the exposed portion R on the upper portion of the shoe 102. Good.

  As shown in FIGS. 2 and 3, the upper support member 16 has a flexible substantially flat plate shape. The thickness is configured such that the tip portion on the toe side is thicker and the thickness is reduced toward the heel side end portion. That is, the toe side tip of the upper side support member 16 is made relatively thick, so that the front tsubo 14 is prevented from falling forward when the portion abuts against the inner surface of the tip of the shoe 102. Can do. Further, since the thickness of the upper side support member 16 is reduced toward the heel side end portion, the grip portion H can be easily gripped with fingers when worn softly. In order to reduce the thickness of the upper side support member 16 from the toe side toward the heel side, the upper side support member 16 may be configured by connecting two or more members. That is, a thick member may be arranged on the toe side, and a thin member may be arranged on the heel side for joining.

  In Example 1, the thickness of the instep support member 16 is configured such that the toe side tip portion is thicker and becomes thinner toward the heel side end portion, but is not necessarily limited thereto, and can be changed as appropriate. It is. For example, the instep support member 16 having a constant thickness may be used, or the toe side tip may be thin, and the thickness may be increased toward the heel end.

  Preferably, the front side support member 16 may be configured such that the front end portion of the upper support member 16 substantially overlaps with the front end portion of the insole body 4 with a space in the front erect direction. Thereby, the front-end | tip part of the upper side support member 16 can be reliably contact | abutted to the inner surface of the front-end | tip part 110 of the shoe 102.

  In the housed state in which the insole 2 is housed in the shoe 102, the outer surface of the upper side support member 16 contacts the upper portion 112 of the shoe 102, friction between the upper portion 112 due to this contact, and the upper side support member The deformation of 16 can also prevent the instep support member 16 from moving toward the tip of the shoe 102. As a result, the front floor 14 is placed between the insole body 4 and the instep support member 16, that is, the shoe 102. It can hold | maintain reliably in the predetermined site | part of an inner front part.

  Preferably, the shoe 102 is provided on at least the outer surface of the upper support member 16 at least in the portion that does not overlap the outer surface of the gripping portion H in the region from the portion that contacts the front side surface 14 of the upper support member 16 to the heel side end. You may provide the holding | maintenance reinforcement | strengthening part F (the part which attached | subjected the oblique line in FIG. 1, FIG. 3) which reinforces the holding | maintenance to the upper cover part. As a result, the insole 2 and the shoe 102 can be more securely held at a predetermined site.

  In the present embodiment, the holding reinforcement portion F is provided with a male surface fastener or a female surface fastener on the outer surface of the upper support member 16. More preferably, a corresponding female surface fastener or a male surface fastener may be provided in a corresponding portion of the shoe 102.

  In the first embodiment, the male surface fastener or the female surface fastener is provided on the outer surface of the upper support member 16 as the holding reinforcement portion F as described above. However, the present invention is not necessarily limited to this and can be appropriately changed. For example, both may be stuck using the adhesive as the holding reinforcement part F, or may be sewn with a thread. That is, it is only necessary that the holding state can be strengthened so that the positional relationship between the insole 2 and the shoe 102 does not shift.

  In the first embodiment, a non-slip member 32 is disposed on the back surface of the toe side front portion 6 of the insole body 4. An appropriate anti-slip shape is applied to the surface of the anti-slip member 32. The anti-slip member 32 is made of a material such as rubber or synthetic rubber, and is fixed to the insole body 4 with an adhesive or the like, for example. By providing the anti-slip member 32, the force from the toe is reliably transmitted to the inner bottom 106 of the shoe 102 via the insole body 4 and the anti-slip member 32, so that walking and running can be stabilized. Moreover, by comprising in this way, the one end part (end part exposed to the back surface of the insole main body 4) of a pair of core ropes 20 and 22 is covered with the non-slip | skid member 32, and one end part of these core ropes 20 and 22 Can be more securely fixed, and the front bottom surface of the insole 2 can be flattened. The anti-slip member 32 can achieve a desired effect by being provided on at least the back surface of the toe-side front portion 6 of the insole body 4, but may be provided on the back surface of the entire insole body.

  Furthermore, in Example 1, a pair of cover member 34 is provided in the inner surface of the back side support member 16 (refer FIG.2, FIG5 and FIG.6). The cover member 34 is formed of, for example, woven fabric, non-woven fabric, leather, rubber, synthetic resin, or the like, and as is understood from the above description, the other end portions of the pair of core cords 20 and 22 (back support member 16). And the other ends of the core cords 20 and 22 can be more reliably fixed.

  As shown in FIG. 7, the insole 2 is accommodated in a shoe 102 such as a walking shoe, an athletic shoe, or a sports shoe, and is placed on the surface of the inner bottom 106 thereof. In this accommodated state, as shown in FIG. 7, the front end portion of the insole body 4 abuts the inner surface of the lower end portion of the front end portion 110 of the shoe 102 and the toe side front end portion of the upper side support member 16 is the front end of the shoe 102. The upper end portion of the portion 110 comes into contact with the inner surface of the upper portion, and the holding reinforcement portion F comes into contact with the inner surface of the upper portion of the shoe 102. Thereby, the movement of the insole body 4 and the instep side support member 16, in other words, the front side 14 to the tip side of the shoe 102 is surely suppressed, and the front side 14 is securely held at the front part in the shoe 102. Can do. Further, on the lower end portion side of the front floor 14, when the shoe 102 is worn, the foot 108 rests on the insole body 4, so that the weight acts on the insole body 4 via the foot 108, which also causes the front The movement of the lower end side of the tsubo 14 is suppressed.

  In the first embodiment, the toe side tip of the upper support member 16 is configured to contact the inner surface of the upper end portion of the tip 110 of the shoe 102. However, the present invention is not limited to this and can be changed as appropriate. is there. For example, the toe side tip of the upper side support member 16 may abut against the inner surface of the upper part of the shoe 102 to suppress the movement of the front grammage 14.

  In order to suppress the movement of the upper end side of the front floor 14 more reliably, it is preferable to provide the holding reinforcing portion F as described above, and thereby, the movement of the upper side support member 16 on the insole 2 side is more reliably performed. And the front floor 14 can always be kept in its original state (upright state or inclined state), and as a result, the ease of wearing of the shoe 102 containing the insole 2 is improved. The Preferably, a male surface fastener or a female surface fastener is provided as the holding strengthening portion F, and a female surface fastener or a male surface fastener that is detachably mounted in accordance with the male surface fastener or the female surface fastener is attached to the inner surface of the shoe 102 main body side. May be provided. As a result, the front floor 14 can be reliably held at a predetermined site in the shoe 102 body. These male surface fasteners or female surface fasteners can be attached with an adhesive or sewed with a thread (or string).

  In the shoe 102 in which the insole 4 is accommodated, the shoe 102 is put on so that the front floor 14 is located in the groin between the first and second heels of the foot 108. When walking (running) with this shoe 102, the front gravel 14 acts on the crotch between the first and second heels, so that the weight shift when walking is straight from the heel toward the first heel. As a result, it is possible to stably walk (run) by transmitting the force of the toes to the shoe sole. In this walking (running) state, the front square 14 acts on the crotch between the first heel and the second heel, so that when the ground is kicked, the tension is applied and force is applied to the toes of the toes, This also makes it possible to stabilize walking (running) and to increase the strength of the toes and soles because of the struts when kicking. As a result, the walking posture is improved, and back pain, knee pain and the like can be prevented. In addition, since the outer shape of the front square 14 is cylindrical (or a polygonal column such as a triangular prism), it is easier to grasp by the first and second heels, thereby making it easier to step on when kicking with a force applied to the toes of the toes, The strength of the toes and soles can be increased.

  As described above, Example 1 of the insole according to the present invention and the shoe equipped with the insole has been described, but the present invention is not limited to such an embodiment, and various modifications or corrections can be made without departing from the scope of the present invention.

  As yet another modification, the front basin 14A and the upper support member 16A may be integrally formed of a synthetic resin or the like. In that case, what is necessary is just to make it attach to the insole body 4 with the lower end side of 14 A of front basins. The upper side support member 16A should just be provided in the end of 14 A of front basins at least.

  As still another modification, the cylindrical elastic sleeve 54 may be omitted. Thereby, a member can be reduced and cost can be reduced. Alternatively, the columnar member 52 may be omitted, and the front grammure may be configured with only the cylindrical elastic sleeve 54.

  As still another modification, the insole main body 4A or the instep side support member 16A and the columnar member 52 are pressed by press-fitting a press-fitting member having a disk whose opposite side is larger than the cylindrical diameter at both ends or one end of the columnar member 52. It is good also as a structure which attaches.

  As still another embodiment, the exposed portion R of the upper support member 16 may not be provided. As a result, the upper side support member 16 is not exposed to the outside from the mouth of the shoe 102, and thus design is ensured in the case of the shoe 102 that does not have a tongue-like member called tongue in the upper part. Can do. Moreover, it is good also as a structure which does not provide the holding part H itself. In this case, when the shoe 102 is worn, the upper support member 16 cannot be gripped and pulled with fingers, but the insole 2 is firmly held by the shoe 102 by the holding reinforcement portion F, so that the shoe 102 is easily worn. Is possible.

  Further, for example, in the above-described embodiment, the description is applied to the shoes 102 such as walking shoes, athletic shoes, and sports shoes. However, the present invention is not limited to these types of shoes, and boots, snow shoes, and boots.
