Description

本発明は、中敷および履物に関する。   The present invention relates to insoles and footwear.

靴、スリッパ、サンダル等の履物には、足の痛みや負担の軽減などを目的として、履物底の上面に中敷を配置することが従来から行われている。従来の中敷として、特許文献1には、シート部の裏面側である底部に複数の凸部が配置された構成が開示されており、これらの凸部による足裏への刺激がシート部を介して行われるように履物の中に敷設することで、凸部が足裏に直接接触する場合の不快感が解消され、適度な刺激によるマッサージ効果が得られるとされている。   For footwear such as shoes, slippers, and sandals, an insole has been conventionally disposed on the upper surface of the footwear bottom for the purpose of reducing foot pain and burden. As a conventional insole, Patent Document 1 discloses a configuration in which a plurality of convex portions are disposed on the bottom portion on the back side of the seat portion, and stimulation of the soles by these convex portions causes the seat portion to be stimulated. By laying in the footwear so as to be carried out, discomfort when the convex part directly contacts the sole of the foot is eliminated, and a massage effect by moderate stimulation is obtained.

ところが、上記従来の中敷は、足裏の全体に刺激を与えることができるように、シート部の底部に多数の凸部が均一に配置されていることから、足裏の全体が凸部により支持される。このため、凸部を備えない一般的な中敷と同様に履物内で中敷の上面に沿った足裏の滑りが生じ易く、踵の内反・外反や足部の外転等を矯正するものとしては十分な効果が得られなかった。   However, the above-mentioned conventional insole has a large number of convex portions arranged uniformly on the bottom of the seat portion so that the entire sole can be stimulated. Supported. For this reason, slipping of the sole along the upper surface of the insole is likely to occur in the footwear in the same way as a general insole that does not have a convex part, and corrects varus / valgus of the heel and abduction of the foot As a result, a sufficient effect was not obtained.

そこで、本発明は、足の骨格の矯正を良好に行うことができ、関節の動きを向上させることができる中敷および履物の提供を目的とする。   Therefore, an object of the present invention is to provide an insole and footwear that can satisfactorily correct the skeleton of the foot and improve the movement of the joint.

本発明の前記目的は、履物底の上面に配置される中敷であって、可撓性を有する中敷本体と、前記中敷本体の裏面側に設けられた中足骨支持突起および踵骨支持突起とを備え、前記中足骨支持突起および踵骨支持突起は、先端を履物底の上面に当接させた状態で前記中敷本体の表面側に足裏を載置することにより、前記中敷本体を介してそれぞれ第5中足骨の外側および踵骨の外側を支持するように配置されており、前記中敷本体と履物底との間には、前記中敷本体の外側縁部に沿って、前記中足骨支持突起から前記踵骨支持突起までの全体にわたって空間部が形成される中敷により達成される。   The object of the present invention is an insole disposed on the upper surface of a footwear bottom, and has a flexible insole body, a metatarsal support protrusion and a rib provided on the back side of the insole body The metatarsal bone support protrusion and the rib support protrusion are mounted on the surface side of the insole body with the tip in contact with the upper surface of the footwear base, It arrange | positions so that the outer side of a 5th metatarsal bone and the outer side of a rib may each be supported through an insole body, Between the said insole body and footwear bottom, the outer edge part of the said insole body And the insole in which a space portion is formed from the metatarsal support protrusion to the radius support protrusion.

この中敷において、前記中足骨支持突起および踵骨支持突起は、突出方向先端側が小径となる段部をそれぞれ有していることが好ましい。   In this insole, the metatarsal bone support protrusion and the rib support protrusion preferably each have a stepped portion having a small diameter on the distal end side in the protruding direction.

また、本発明の前記目的は、上述した中敷を、前記中足骨支持突起および踵骨支持突起の先端が履物底の上面に当接するように配置した履物により達成される。   In addition, the object of the present invention is achieved by footwear in which the insole described above is disposed such that the tips of the metatarsal support protrusion and the rib support protrusion are in contact with the upper surface of the footwear bottom.

以下、本発明の実施の形態について、添付図面を参照して説明する。図1は、本発明の一実施形態に係る中敷の背面図である。図1に示すように、中敷1は、足裏形状に合わせて形成された中敷本体10と、中敷本体10の裏面側に設けられた中足骨支持突起20および踵骨支持突起30とを備えている。この中敷1は、履物に対して、中足骨支持突起20および踵骨支持突起30の先端が履物底に当接するように収容され、使用者の足裏が中敷本体10の表面側に載置される。   Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a rear view of an insole according to an embodiment of the present invention. As shown in FIG. 1, the insole 1 includes an insole body 10 formed in accordance with the sole shape, and a metatarsal support protrusion 20 and a rib support protrusion 30 provided on the back side of the insole body 10. And. The insole 1 is accommodated with respect to the footwear such that the tips of the metatarsal support protrusions 20 and the rib support protrusions 30 are in contact with the footwear bottom, and the user's sole is on the surface side of the insole body 10. Placed.

中敷本体10は、例えばポリエチレンやポリプロピレン等の合成樹脂からなり、単層であってもよく、あるいは、ウレタン層およびスポンジ層などの2層以上の積層構造であってもよい。中敷本体10の材質や厚みは、可撓性を有する限り特に限定されるものではなく、従来公知の中敷を使用することができる。   The insole body 10 is made of, for example, a synthetic resin such as polyethylene or polypropylene, and may be a single layer or may be a laminated structure of two or more layers such as a urethane layer and a sponge layer. The material and thickness of the insole body 10 are not particularly limited as long as they have flexibility, and conventionally known insole can be used.

中足骨支持突起20および踵骨支持突起30は、中敷本体10の裏面側に突出するように円柱状に形成されている。図2の平面図において破線で示すように、中敷本体10の表面側に足裏を載置した状態で、この中敷本体10を介して、中足骨支持突起20は第5中足骨Mを支持し、踵骨支持突起30は踵骨Caの外側を支持するように、それぞれ配置されている。足裏のサイズや形状は個人差があるため、中敷本体10における中足骨支持突起20および踵骨支持突起30の位置を正確に特定することは困難であるが、中足骨支持突起20および踵骨支持突起30の少なくとも一部は、平面視において第5中足骨Mおよび踵骨Ca外側と重なり合うように配置されることが好ましい。特に、図2に示すように、中足骨支持突起20の中心が、第5中足骨Mの指節関節近傍の直下に配置され、踵骨支持突起30の中心が、踵骨Caの外側における立法骨Cu近傍の直下に配置されることが好ましく、これによって、踵骨の外反や、距骨骨頭の内反、足部の外転を矯正する効果を最大限に発揮して、硬くなった関節の動きを向上させることができる。中敷本体10を足裏のサイズに合わせて切断する場合には、中足骨支持突起20および踵骨支持突起30の配置が上述した最適な配置になるべく近づくように、サイズ毎の切断線が予め設定された型紙を用いることが好ましい。中足骨支持突起20および踵骨支持突起30の材質は特に限定されず、例えば金属材料等であってもよいが、ゴム、ウレタン、フェルト、スポンジ等のように適度な強度と弾性を備えるものが好ましい。   The metatarsal bone support protrusion 20 and the rib support protrusion 30 are formed in a columnar shape so as to protrude to the back surface side of the insole body 10. As shown by a broken line in the plan view of FIG. 2, the metatarsal support protrusion 20 is connected to the fifth metatarsal via the insole body 10 with the sole placed on the surface side of the insole body 10. M is supported, and the rib support protrusions 30 are arranged so as to support the outside of the rib Ca. Since the size and shape of the sole varies among individuals, it is difficult to accurately specify the positions of the metatarsal support protrusions 20 and the rib support protrusions 30 in the insole body 10, but the metatarsal support protrusion 20 It is preferable that at least a part of the rib supporting protrusion 30 is disposed so as to overlap the outer side of the fifth metatarsal bone M and the rib Ca in plan view. In particular, as shown in FIG. 2, the center of the metatarsal support projection 20 is disposed immediately below the phalangeal joint of the fifth metatarsal M, and the center of the radius support projection 30 is located outside the radius Ca. It is preferable to be placed directly under the vicinity of the leg bone Cu in order to maximize the effects of correcting the valgus of the radius, the varus of the talus, and the abduction of the foot. Can improve joint movement. When cutting the insole body 10 according to the size of the sole, the cutting line for each size is set so that the arrangement of the metatarsal support protrusions 20 and the rib support protrusions 30 is as close as possible to the optimal arrangement described above. It is preferable to use a preset paper pattern. The material of the metatarsal bone support protrusion 20 and the rib support protrusion 30 is not particularly limited, and may be, for example, a metal material or the like, but has moderate strength and elasticity such as rubber, urethane, felt, sponge, etc. Is preferred.

図3は、図1に示す中敷1を矢示A方向にみた側面図である。中足骨支持突起20および踵骨支持突起30は、突出方向先端側が小径となるようにそれぞれ段部22,32が形成されており、この小径部分の先端部24,34が履物底(図示せず)に当接する。段部22,32を備える中足骨支持突起20および踵骨支持突起30の形状は、必ずしも円柱状に限定されるものではなく、例えば、大ブロックの先端にこれよりも断面が小さい小ブロックを備える構成であってもよい。また、段部22,32は必須のものではなく、例えば、中足骨支持突起20および踵骨支持突起30を、突出方向の全体にわたって断面一定に形成してもよく、あるいは、先細の円錐台状あるいは角錐台状等に形成することもできる。   FIG. 3 is a side view of the insole 1 shown in FIG. The metatarsal bone support protrusion 20 and the rib support protrusion 30 are respectively formed with step portions 22 and 32 so that the front end side in the protruding direction has a small diameter, and the front end portions 24 and 34 of the small diameter portion are footwear bottoms (not shown). A). The shapes of the metatarsal bone support protrusions 20 and the rib support protrusions 30 provided with the step portions 22 and 32 are not necessarily limited to a columnar shape. For example, a small block having a smaller cross section than the large block is provided at the tip of the large block. The structure provided may be sufficient. Further, the step portions 22 and 32 are not essential. For example, the metatarsal bone support protrusion 20 and the rib support protrusion 30 may be formed to have a constant cross-section throughout the protrusion direction, or a tapered truncated cone. It can also be formed into a shape or a truncated pyramid shape.

上記の構成を備える中敷1は、図4に示すように、中足骨支持突起20および踵骨支持突起30の先端が、靴などの履物40の履物底42の上面に当接するように配置される。これにより、中敷本体10と履物底42との間には、中敷本体10の外側縁部に沿って、中足骨支持突起20から踵骨支持突起30までの全体にわたって空間部Sが形成される。中敷1が収容される履物40は、履物底42の上面に中敷1を保持可能であればよく、靴以外にスリッパやサンダル、ブーツ等であってもよい。中敷1は履物40に対して着脱可能であってもよく、あるいは、中敷1を履物底42の上面に接着する等して一体化してもよい。   As shown in FIG. 4, the insole 1 having the above-described configuration is disposed such that the tips of the metatarsal bone support protrusion 20 and the rib support protrusion 30 are in contact with the upper surface of the footwear bottom 42 of the footwear 40 such as shoes. Is done. Thus, a space S is formed between the insole body 10 and the footwear bottom 42 along the outer edge of the insole body 10 from the metatarsal support protrusion 20 to the rib support protrusion 30. Is done. The footwear 40 in which the insole 1 is accommodated only needs to be able to hold the insole 1 on the upper surface of the footwear bottom 42, and may be slippers, sandals, boots or the like in addition to shoes. The insole 1 may be detachable from the footwear 40 or may be integrated by bonding the insole 1 to the upper surface of the footwear bottom 42.

本実施形態の中敷1によれば、中敷本体10の表面側に足裏を載置することにより、中足骨支持突起20および踵骨支持突起30が、中敷本体10を介して第5中足骨Mおよび踵骨Ca外側を支持することにより、踵の内反・外反や足部の外転等の状態を矯正することができ、足首・膝・股関節等の違和感や不具合を軽減することができる。   According to the insole 1 of the present embodiment, the metatarsal support protrusions 20 and the rib support protrusions 30 are provided via the insole body 10 by placing the soles on the surface side of the insole body 10. 5 By supporting the metatarsal bone M and the outer side of the rib Ca, it is possible to correct the varus and valgus of the heel, the abduction of the foot, and so on. Can be reduced.

更に、中敷本体10と履物底42との間には、中敷本体10の外側縁部に沿って、中足骨支持突起20から踵骨支持突起30までの全体にわたって空間部Sが形成されるので、中敷10は、足裏の載置により、中足骨支持突起20と踵骨支持突起30との間で、体重により凹状のたわみ変形が生じる。したがって、中敷10のこの凹状部分で足裏の外側を確実に保持することができるので、中足骨支持突起20および踵骨支持突起30による上記効果をより確実に得ることができ、第5中足骨基部骨折(いわゆるJones骨折)の予防も図ることができる。中足骨支持突起20および踵骨支持突起30の高さは、空間部Sにより足裏を保持できる最小限の高さを確保することが好ましく、例えば、5mm程度である。   Further, a space S is formed between the insole body 10 and the footwear bottom 42 along the outer edge of the insole body 10 from the metatarsal support protrusion 20 to the rib support protrusion 30. Therefore, in the insole 10, a concave bending deformation occurs due to the weight between the metatarsal support protrusions 20 and the rib support protrusions 30 due to the placement of the soles. Therefore, since the outside of the sole can be reliably held by this concave portion of the insole 10, the above-mentioned effect by the metatarsal bone support protrusion 20 and the rib support protrusion 30 can be obtained more reliably, and the fifth Metatarsal base fracture (so-called Jones fracture) can also be prevented. The heights of the metatarsal support protrusions 20 and the rib support protrusions 30 are preferably secured to a minimum height at which the sole can be held by the space S, for example, about 5 mm.

中敷1は、中足骨支持突起20および踵骨支持突起30以外には突起を備えない構成であることが好ましく、特に中足骨支持突起20と踵骨支持突起30との間には、突起などの異物を備えないようにして空間部Sを確実に形成し、中敷本体10の変形を妨げないようにする必要がある。但し、本発明の上記効果を奏する限り、空間部S以外の部分で中敷本体10の表面または裏面に付加的な構成要素を備えることは可能である。   The insole 1 is preferably configured to have no protrusions other than the metatarsal support protrusions 20 and the rib support protrusions 30, and in particular, between the metatarsal support protrusions 20 and the rib support protrusions 30, It is necessary to reliably form the space S so as not to include foreign matters such as protrusions and to prevent the deformation of the insole body 10. However, as long as the above-described effect of the present invention is exhibited, it is possible to provide additional components on the front surface or the back surface of the insole body 10 in portions other than the space portion S.

また、本実施形態の中足骨支持突起20および踵骨支持突起30は、突出方向先端側が小径となる段部32,42を備えるため、中足骨支持突起20および踵骨支持突起30の必要な強度および高さを確保しつつ、中足骨支持突起20と踵骨支持突起30との間における中敷本体10のたわみ変形を容易にすることができる。   Further, since the metatarsal support protrusion 20 and the rib support protrusion 30 of the present embodiment include the step portions 32 and 42 having a small diameter on the distal end side in the protruding direction, the metatarsal support protrusion 20 and the rib support protrusion 30 are necessary. It is possible to easily deform the insole body 10 between the metatarsal bone support protrusion 20 and the rib support protrusion 30 while ensuring a sufficient strength and height.
