  JP 2005-296604 A   JP 2001-258610 A   JP 2001-190302 A   JP 2001-238703 A   JP-A-9-191904   JP 2004-283500 A.

  By the way, when purchasing shoes, shoes of a size that matches the size of one's feet are usually selected. In this case, if there is a small size margin between the shoes, for example, wearing shoes In particular, since there is a concern that the fingertip or the heel may be damaged due to contact with the inner surface of the shoe, it is common to select a shoe having a size slightly larger than the size of the foot. Therefore, when the shoe is worn, a gap inevitably exists between the inner surface of the toe portion of the shoe and the fingertip.

  On the other hand, the presence of a gap in the length direction between the inner surface of the toe portion of the shoe and the fingertip means that the foot can slip in the front-rear direction in the shoe when the shoe is worn. For this reason, when designing the shape and dimensions of a shoe in consideration of such points, both sides of the instep of the foot are held from the outside by both sides of the inner surface of the shoe and restrained in the longitudinal direction of the foot. To prevent slipping.

  However, the restraint of the foot due to this hugging action has the useful effect of suppressing the slipping of the foot in the shoe, but if this is excessive, the instep of the foot is damaged by contact with the inner side of the shoe. Therefore, the actual situation is that the degree of restraint of the foot due to the hugging action is kept relatively low by comparing these advantages and disadvantages.

  As a result, slipping of the foot is likely to occur particularly in sports shoes, etc., where there is a great opportunity to apply a relatively large load in the front and back or left and right directions to the toe portion during the activity of wearing the shoes. For example, the tension on the fingertip part does not work, agile movement, stable movement cannot be taken, the fit with the shoes or the sense of unity with the shoes is impaired and good comfort is not obtained, etc. In addition to bodily sensation problems, physical problems such as injuries to the fingertips or induction of hallux valgus due to continuous excessive load on the feet may be considered.

  In addition, safety during walking while wearing shoes is realized for the first time with a sense of unity between the foot and the shoe, and slipping of the foot due to the presence of the gap as described above is Safety of walking is impaired because it impairs the sense of unity with shoes and, for example, can be an obstacle to walking for elderly people or persons with reduced physical activity such as physically handicapped. This is a problem that cannot be overlooked in view of the arrival of an aging society.

  Therefore, in view of the above problems, the present invention has an object to provide an insole for a shoe that sufficiently exhibits the original functions of a shoe and has a protective effect on a fingertip portion.

  The present invention employs the following configuration in order to solve the above problems.

  In the first invention of the present application, in the insole 2 laid on the inner bottom surface 1f of the shoe 1, the insole 2 has a substantially flat plate-like body portion 21 having a planar shape substantially matching the shape of the inner bottom surface 1f. And an outer surface shape that is located at the distal end portion 21 a of the main body portion 21 and substantially matches the inner surface shape of the toe portion 1 a of the shoe 1, and the rear side end portion of the foot 50 of the user who wears the shoe 1. It is characterized in that the fingertip position and the tip structure portion 22 formed as a fingertip contact portion 22a that overlaps by a predetermined amount are integrally formed by foam molding of a low resilience resin material.

  In the second invention of the present application, in the insole for shoes according to the first invention, the main body portion 21 has a planar shape and a size substantially matching the shape of at least the front half portion of the inner bottom surface 1f. It is characterized by that.

  According to a third invention of the present application, in the insole for shoes according to the first or second invention, the fingertip contact portion 22a is substantially in the shape of a fingertip continuous line connecting the fingertip positions of the fingers of the user. It is characterized in that it is set to a matching plan view shape.

  In the fourth invention of the present application, in the insole for shoes according to the first or second invention, the fingertip abutting portion 22a has a planar view shape that substantially matches the fingertip shape of each finger of the user. It is characterized by setting.

  In the fifth invention of the present application, in the insole for shoes according to the first, second, third, or fourth invention, the main body portion 21 is more than the planar shape of the inner bottom surface 1f of the shoe 1 by a predetermined amount. The feature is that it is set to a large planar shape.

  In a sixth invention of the present application, in the first, second, third, fourth, or fifth invention, a portion of the main body portion 21 corresponding to the arch portion 55 of the user's foot 50 is It is characterized by providing an intermediate raised portion 23 that is raised upward from the surface of the main body portion 21.

  In the seventh invention of the present application, in the first, second, third, fourth, or fifth invention, an outer peripheral bulge that protrudes upward from the surface of the main body 21 to the outer peripheral edge portion of the main body 21. A feature is that the portion 24 is provided.

  (A) In the insole for shoes according to the first invention of the present application, a substantially flat main body portion 21 having a planar shape substantially matching the shape of the inner bottom surface 1f of the shoe 1 and the distal end portion 21a of the main body portion 21 A fingertip abutting portion that has an outer surface shape that is positioned and substantially matches the inner surface shape of the toe portion 1a of the shoe 1 and whose rear side end portion overlaps with the fingertip position of the user's foot 50 wearing the shoe 1 by a predetermined amount. The tip constituting portion 22 which is 22a is integrally formed by foam molding of a low resilience resin material. Therefore, the shoe insole according to the present invention has the following specific effects.

(A-1) When the shoe 1 is worn while the insole 2 is laid on the inner bottom surface 1f of the shoe 1, the fingertip of the foot 50 comes into contact with the fingertip contact portion 22a of the tip constituting portion 22 and this is appropriately pressed and deformed. Since the elastic repulsion force accompanying the deformation of the tip component 22 acts on the fingertip, the tip component 22 fills a gap existing between the fingertip of the foot 50 and the toe inner surface of the shoe 1. Thus, the foot 50 has an appropriate restraining action due to the elastic repulsive force, and the integrity of the shoe 1 and the foot 50 is promoted. Therefore, for example, even when a relatively large load in the front / rear direction or the left / right direction is applied to the toe portion during the activity of wearing shoes, the foot 50 slips due to the elastic repulsion of the tip component 22. As a result, struts at the fingertips are effective, agile movements and stable movements can be realized, and the original function of the shoe 1 is fully exhibited. Become.

(A-2) In addition, such suppression of foot slip has an effect of enhancing the sense of unity between his / her foot and the shoe 1 for the person who wears the shoe 1, and therefore, By obtaining a sense of unity with shoes, for example, when an elderly person or a person with reduced foot activity such as a disabled person walks wearing shoes, the safety of walking is ensured and the effect Is secured by simple and inexpensive means of laying the insole 2, it has extremely high utility in an aged society.

(A-3) Furthermore, even if the foot 50 receives a sudden load in the front-rear or left-right direction and causes a temporary slip, the load is reduced or eliminated and the foot 50 is in a slipping state. Accordingly, the tip constituting portion 22 slowly returns to its initial state, and the elastic restraining action on the fingertip portion of the foot 50 is recovered. Therefore, the function of protecting the foot 50 by the tip constituting portion 22 is restored. Is maintained for a long time.

(A-4) Since the tip constituent part 22 is formed by foam molding of a low-resilience resin material, the elastic repulsive force accompanying the deformation of the tip constituent part 22 is not excessive and is moderately suppressed. Even if the shoe 1 is worn for a long time, it does not place an excessive burden on the fingertip. For example, problems such as damage to the fingertip portion or induction of hallux valgus are prevented, and safety in wearing the shoe 1 And reliability is increased.

(A-5) Since the main body portion 21 and the tip component portion 22 are integrally formed by foam molding of a low-resilience resin material, the main body portion 21 follows the shape of the corresponding sole portion, and Since the tip constituting portion 22 is elastically deformed along the shape of the corresponding fingertip portion, a high fit between the foot 50 and the shoe 1 is ensured, and the load applied to the sole portion and the fingertip portion is medium. The protective performance of the shoe 1 with respect to the foot 50 is further improved through the support 2.

  (B) According to the insole for shoes according to the second invention of the present application, in addition to the effect described in (a) above, the following specific effect is obtained. That is, in the present invention, the main body portion 21 has a planar shape and size substantially matching the shape of at least the front half portion of the inner bottom surface 1f, so that the heel height is high and the forward tilt angle is large. When applied to shoes having wear characteristics such as a large force applied to the fingertip portion of the foot 50 during use, for example, high heels for women, protection of the fingertip portion is ensured.

  (C) According to the insole for shoes according to the third invention of the present application, in addition to the effect described in the above (a) or (b), the following specific effect is obtained. That is, in the present invention, the fingertip contact portion 22a is set in a planar view shape that substantially matches the shape of the fingertip continuous line connecting the fingertip positions of each finger of the user. However, it is set to the minimum necessary to achieve the protection function of the fingertip portion of the foot 50, the effective use of the low-resilience resin material that is the material of the insole 2 is realized, and the function of the insole 2 is secured. And cost reduction are promoted.

  (D) According to the insole for shoes according to the fourth invention of the present application, in addition to the effect described in the above (a) or (b), the following specific effect is obtained. That is, in the present invention, the fingertip abutting portion 22a is set in a plan view shape that substantially matches the fingertip shape of each finger of the user. The amount of deformation of the tip component 22 that is deformed by contact with each other, and consequently, the elastic repulsion force accompanying the deformation is made as uniform as possible between the fingers, A feeling of fitting to shoes 1 becomes good.

  (E) According to the insole for shoes according to the fifth invention of the present application, in addition to the effects described in the above (a) or (b), the following specific effects can be obtained. In other words, in the present invention, the main body portion 21 is set to a planar shape that is larger than the planar shape of the inner bottom surface 1f of the shoe 1 by a predetermined amount. Since not only the sole part but also the arcuate surface part from the sole periphery to the foot surface side, the peripheral part of the main body portion 21 is deformed along the arcuate surface and fits therewith. Further improvement in protection performance against this can be expected.

  (F) According to the insole for shoes according to the sixth invention of the present application, in addition to the effects described in (a), (b), (c), (d) or (e), A unique effect is obtained. In other words, in the present invention, the intermediate raised portion 23 that protrudes upward from the surface of the main body portion 21 is provided in a portion of the main body portion 21 corresponding to the arch portion 55 of the user's foot 50. 1, the intermediate raised portion 23 is deformed by receiving a pressing force from the arch portion 55 of the foot 50, and a repulsive force accompanying the deformation is constantly applied to the arch portion 55. The forming action is promoted, and the improvement effect of flat feet can be expected.

  (G) According to the insole for shoes according to the seventh invention of the present application, in addition to the effects described in (a), (b), (c), (d) or (e), A unique effect is obtained. In other words, according to the present invention, the outer peripheral bulge portion 24 that protrudes upward from the surface of the main body portion 21 is provided at the outer peripheral edge portion of the main body portion 21. In this case, the arcuate surface portion from the sole periphery to the front surface side of the foot 50 corresponds to a corner portion between the side portion and the inner bottom surface of the shoe 1, and a gap extending in the peripheral direction is formed between the portion. Where the outer peripheral bulge 24 is provided at the outer peripheral edge of the main body 21, the outer peripheral bulge 24 is elastically deformed between the foot 50 side surface and the shoe 1 side surface. Thus, the gap is filled, the fit of the arcuate surface portion from the sole periphery to the front side of the foot is secured, the comfort of the shoe 1 is improved, and the protection of the entire foot 50 can be promoted.

  Hereinafter, the present invention will be specifically described based on preferred embodiments.

A: First Embodiment FIG. 1 shows a shoe insole 2 according to a first embodiment of the present invention and a shoe 1 to which this is applied. FIG. 2 shows a state in which the insole 2 is laid in the shoe 1.
A-1: Shoes 1

  The shoe 1 is a well-known male leather shoe, 1a is a toe part, 1b is a heel part, 1c and 1d are a pair of left and right side parts, 1e is an arch support part, 1f is an inner bottom face 1f, 1g is An instep portion, 1h indicates a cuff portion, and 1j indicates a rear side portion. By laying the insole 2 described below on the inner bottom surface 1f of the shoe 1, it is possible to reliably exhibit the effective functions inherently possessed by the shoe 1, and the commercial value and use value thereof are improved.

  In addition, although the men's leather shoes are shown here as the said shoes 1, this is mentioned as an example of the shoes to which the said insole 2 is applied, and "the shoes" to which the present invention can be applied are The present invention is not limited to men's leather shoes, and can be applied to a wide variety of shoes such as competition shoes such as golf shoes and tennis shoes, cloth shoes such as sneakers and athletic shoes, and high heels for women.

A-2: Insole 2
The insole 2 constitutes the gist of the present invention, and is characterized by its material characteristics and unique shape, and has a substantially flat body portion 21 and a tip of the body portion 21. The tip structure part 22 located in the part 21a is provided.

  As shown in FIGS. 1 to 3, the main body portion 21 is a flat plate body having a predetermined thickness having a planar shape along the shape of the inner bottom surface 1 f of the shoe 1 so as to cover the entire area of the inner bottom surface 1 f. In this embodiment, in particular, the outer dimension in plan view is set to be larger than the outer dimension of the inner bottom surface 1f of the shoe 1 by a predetermined dimension, and the peripheral edge in the laid state on the inner bottom surface 1f. The portion can also correspond to a corner portion of the inner bottom surface 1f and a side surface portion continuous therewith (see FIGS. 2, 8, and 9).

  And the said main-body part 21 has the front-end | tip part 21a corresponding to the fingertip part 52 of the leg 50, the rear-end part 21b corresponding to the heel part 54, the side parts 21c and 21d corresponding to the both sides of the upper part 51, Although each part of the arch corresponding | compatible part 21e corresponding to the arch part 55 is provided, in this embodiment, the thickness is set substantially equal to these each part. In this case, the thickness of the main body 21 is preferably in the range of 5 mm to 15 mm. When the thickness is 5 mm or less, it is difficult to ensure elasticity after deformation, and when the thickness is 15 mm or more, the load supporting form after deformation is not stable.

  In other embodiments, as shown in FIG. 1 and FIG. 3, the arch corresponding portion 21e may be locally raised to provide an intermediate raised portion 23. In such a configuration, when the shoe 1 is worn, the intermediate raised portion 23 is deformed by receiving the pressing force from the upper step portion 55 of the foot 50, and the repulsive force accompanying the deformation is always the arch portion. 55, the formation of the arch portion 55 is promoted, and as a result, the improvement effect of flat feet can be expected.

  The tip component 22 is integrally formed with the tip 21a of the main body 21 so as to protrude upward from the tip 21a, as shown in FIGS. The outer peripheral portion 22b has a curved surface that conforms to the inner shape of the toe portion 1a of the shoe 1, and the rear end surface of the outer peripheral portion 22b constitutes a fingertip abutting portion 22a. It is set to a planar view shape that substantially matches the shape of the fingertip continuous line that connects the fingertip positions of the fingers.

  In this case, as shown in FIGS. 5 and 6, the formation position of the insole 2 of the fingertip abutting portion 22 a is such that the foot 50 is in a worn state with the foot 50 inserted into the shoe 1. The fingertip portion 52 corresponds to the fingertip contact portion 22a, and the tip portions of the fingers 52a to 52e are set to positions where the fingertip contact portion 22a can be pressed and appropriately deformed forward. .

  Since the insole 2 has a wide range of types and shapes of shoes to which the insole 2 is applied as described above, a plurality of insole 2 shapes and dimensions are prepared corresponding to the application target. . In particular, the tip constituting portion 22 of the insole 2 needs to have a function of filling a gap between the inner surface of the toe portion 1a of the shoe 1 and the fingertip portion 52 of the foot 50 that occurs when the shoe 1 is worn. Therefore, when setting the shape, it is necessary to correspond to the inner surface shape of the toe portion 1a of the shoe 1.

  Here, the insole 2 is an open-cell foamed molded article obtained by foaming molding a low-resilience resin material mainly composed of polyol and polyisocyanate, and having the characteristics as Due to various performances based on low resilience (that is, having both elasticity and viscosity, and high shock absorption, stress dispersibility, and resilience), characteristics suitable as an insole are imparted. And from the viewpoint of obtaining such characteristics, the low-resilience resin material is slightly different depending on the use conditions of the shoe (how to apply force, the magnitude of the force, etc.), A material having a rebound resilience (based on JIS K 6400) of 15% or less and a hardness (25% hardness based on JIS K 6400) of about 50 to 150 N is preferable.

A-3: Effect of Insole 2 FIG. 2 shows a state in which the insole 2 is inserted into the shoe 1 and laid on the inner bottom surface 1f. In this state, the body portion 21 of the insole 2 abuts against the inner bottom surface 1 f of the shoe 1, and the outer peripheral portion 22 b of the tip component portion 22 contacts the inner surface of the toe portion 1 a of the shoe 1. Negotiated.

  4 to 9 show a wearing state in which a person inserts a foot 50 into the shoe 1 in the laying state of the insole 2 shown in FIG. In the side view in the worn state, as shown in FIG. 4, the main body portion 21 of the insole 2 is elastically deformed by the pressing force applied to the sole portion 53, but in this case, the low resilience resin material Due to the characteristic, it deforms flexibly along the surface shape of the sole 53 and adheres to the entire area of the sole 53, and the force applied to the sole 53 is dispersed and supported throughout the sole 53.

  Such adhesion and dispersive support of force can be achieved in the heel part 54 of the foot 50 (see FIGS. 4 and 9), both sides of the upper 51 (see FIG. 7), and the arch 55 (see FIG. 8). It is realized similarly. As a result, an excessive load is not applied to the sole portion 53 portion, and the sole portion 53 portion is protected.

  Further, also in the corner portion of the shoe 1, as shown in FIGS. 7 to 10, the peripheral portion of the main body portion 21 of the insole 2 is in close contact with the corner shape, and The slipping of the 50 in the front-rear and left-right directions is suppressed as much as possible, thereby ensuring a stable comfort.

  On the other hand, at the tip constituting portion 22 portion of the insole 2, the outer peripheral portion 22b of the tip constituting portion 22 abuts against the inner surface of the toe portion 1a of the shoe 1 as shown in FIGS. It is deformed along each inner shape. Further, on the fingertip contact portion 22a side of the distal end configuration portion 22, the fingertip contact portion 22a portion receives a pressing force from each finger 52a to 52e of the foot 50, so that the tip shape of each finger 52a to 52e is obtained. Appropriately deformed forward in conformity.

  Therefore, a moderate repulsive force is generated in the front-rear direction portion 22 in the front-rear direction due to the synergistic action of the deformation on the outer peripheral portion 22b side and the deformation on the fingertip contact portion 22a side. Since the tip constituting portion 22 exists in a compressed deformation state in the gap between the inner surface of the portion 1a and the fingertip of the foot 50 and fills the gap, the synergistic action of the shoe 1 and the foot 50 A bodily sensation and fit are obtained, and a good comfort is obtained. Further, even if a load in the front-rear direction is applied to the foot 50, this load is dispersed and absorbed by the distal end component 22, and a restraining action due to elastic deformation of the distal end component 22 acts on the foot 50. Therefore, there is no great slippage on the foot 50, and a stable and reliable comfort can be obtained.

  Protective action and restraining action on the sole part 53 of the foot 50 and its peripheral part on the body part 21 side of the insole 2 as described above, and protective action on the fingertip part 52 of the foot 50 in the tip constituting part 22 When the restraining action cooperates with each other, for example, even if a relatively large front-to-back or left-right load is applied to the fingertip portion of the foot 50 during the activity of wearing shoes, As a result, it is possible to prevent the foot 50 from slipping due to the elastic repulsion of the tip component 22, and as a result, the struts at the fingertips are effective, and an agile movement or a stable movement can be realized. The original function of the shoe 1 is fully exhibited.

  In addition, by suppressing the slipping of the foot in this way, a sense of unity between the foot and the shoe 1 is enhanced for the person wearing the shoe 1, and as a result, for example, an elderly person or a disabled person When a person with a reduced activity function of his / her foot wears shoes and walks, the safety of walking is ensured and the effect is secured by a simple and inexpensive means of laying the insole 2, so that It has extremely high usefulness in the society.

  Further, even if the foot 50 receives a sudden load in the front-rear or left-right direction and causes a temporary slip, if the load is reduced or eliminated and the foot 50 returns from the slip state, Accordingly, the shape of the distal end component 22 is also slowly restored to the initial state, and the elastic restraining action on the fingertip portion of the foot 50 is recovered. Therefore, the protection function of the foot 50 by the distal end component 22 is maintained for a long period of time. Is done.

  Further, since the tip constituent portion 22 is formed by foam molding of a low resilience resin material, the elastic repulsive force accompanying the deformation of the tip constituent portion 22 is not excessive and can be moderately suppressed. Even if it is worn for a long time, it does not place an excessive burden on the fingertip. For example, problems such as damage to the fingertip portion or induction of hallux valgus are prevented, and safety and reliability in wearing the shoe 1 are prevented. Is increased.

  Further, since the main body portion 21 and the tip component portion 22 are integrally formed by foam molding of a low resilience resin material, the main body portion 21 follows the surface shape of the corresponding foot portion 53, and the tip portion Since the component part 22 is elastically deformed along the shape of the corresponding fingertip part 52, a high fit between the foot 50 and the shoe 1 is ensured, and the load applied to the sole part 53 and the fingertip part 52 Is distributed and supported through the insole 2, and the protection performance of the shoe 1 against the foot 50 is further improved.

  Furthermore, in this embodiment, the fingertip contact portion 22a is set to have a planar view shape that substantially matches the shape of the fingertip continuous line that connects the fingertip positions of each finger of the user. The size is set to the minimum necessary for achieving the protection function of the fingertip portion 52 of the foot 50, and the low-resilience resin material that is the material of the insole 2 is effectively used. Both the securing of the function 2 and cost reduction are promoted.

  In the insole 2, as described above, the main body 21 is set to a planar shape larger than the planar shape of the inner bottom surface 1 f of the shoe 1 by a predetermined amount. In the state, not only the fingertip and sole portion of the foot 50 but also the arc-shaped surface portion from the foot periphery to the foot surface side, the peripheral portion of the main body portion 21 is deformed along the arc-shaped surface. Therefore, further improvement in the protection performance for the foot 50 can be expected.

  As shown in FIG. 1, the intermediate bulge that protrudes upward from the surface of the main body portion 21 at a portion corresponding to the arch portion 55 of the user's foot 50 in the main body portion 21 of the insole 2. If the portion 23 is provided, the intermediate raised portion 23 is deformed by receiving a pressing force from the arch portion 55 of the foot 50 in the wearing state of the shoe 1, and the repulsive force accompanying the deformation is always the upper step portion. 55, the formation of the arch portion 55 is promoted, and as a result, the improvement effect of flat feet can be expected.

The insole 2 of this embodiment has the same basic configuration as that of the first embodiment, and the difference is that the tip insole part 2 of the insole 2 of the first embodiment is different. The 22 fingertip contact portions 22a are set to have a planar view shape that substantially matches the shape of the fingertip continuous line that connects the fingertip positions of each finger of the user. The fingertip contact portion 22a is set to a planar view shape that substantially matches the fingertip shape of each finger of the user.

  By setting the shape of the fingertip abutting portion 22a of the tip component 22 in this way, the deformation of the tip component 22 deformed by contact with the fingertip of the foot 50 when the shoe 1 is worn. As a result, the elastic repulsive force due to deformation is made as uniform as possible between the fingers, and the sense of restraint of the foot 50 by the tip component 22 and the fit to the shoe 1 become even better. .

  In addition, since a structure and effect other than this are the same as the case of the said 1st Embodiment, it respond | corresponds to each member shown in each figure which concerns on each member of FIG.10 and FIG.11 according to 1st Embodiment. Therefore, the same reference numerals are used, and the corresponding description in the first embodiment is used to omit the description here.
