Embodiment of the Invention

以下、図面を参照しながら本発明の各種態様に係る筋肉トレーニング器に関して説明する。以下の説明は本発明の技術思想を具現化する幾つかの具体例を説明するものであり、本発明は以下の説明に限定されるものではない。 Hereinafter, the muscle training device according to various aspects of the present invention will be described with reference to the drawings. The following description will explain some specific examples that embody the technical idea of the present invention, and the present invention is not limited to the following description.

図１は本発明の一態様に係る筋肉トレーニング器の全体の形態を示す斜視図（ａ）と一部分の形態を示す平面図（ｂ）と斜視図（ｃ）と（ｄ）である。図１（ａ）の筋肉トレーニング器は上面に足を乗せる足置き部２を有する足置き部材１と足置き部材１の伸縮部材取り付け部１３に取り付けられた紐状の伸縮部材３とを有し、伸縮部材３の他片側の先方には足先を掛ける帯状の足掛け部４が形成されている。これを使用するには足置き部２に片足を乗せて立ち、他方の足先を足掛け部４に掛けて動かし、伸縮部材３を任意の方向に引き伸ばす。こうすると伸縮部材３が伸縮機能を有しているので、引き伸ばすことにより張力が生じ、足腰の筋肉に負荷を与えることができる。左右の足を交換することにより、他片側にも同様に負荷を与えることができ、左右の足腰の筋肉を鍛えることができる。 FIG. 1 is a perspective view (a) showing an overall configuration of a muscle training device according to an aspect of the present invention, a plan view (b) showing a partial configuration, and perspective views (c) and (d). The muscle training device of FIG. 1A has a footrest member 1 having a footrest portion 2 for placing a foot on the upper surface, and a string-like elastic member 3 attached to an elastic member attachment portion 13 of the footrest member 1. A belt-like footrest portion 4 is formed on the other side of the elastic member 3 to hang the foot. In order to use this, the user puts one foot on the footrest 2 and moves the other foot on the footrest 4 to stretch the telescopic member 3 in an arbitrary direction. In this way, since the elastic member 3 has an expansion / contraction function, tension is generated by stretching, and a load can be applied to the muscles of the legs. By exchanging the left and right legs, the other side can be similarly loaded, and the muscles of the left and right legs can be trained.

次ぎに各部分の詳細に就いて説明する。足置き部材１は足を乗せるための台座である。図１（ａ）では板状の部材で示されているが、形状は任意であり、足を乗せられる大きさを有していれば良い。実施上、縦横の寸法が其々１０ｃｍ以上で、高さは１０ｃｍ以下が好ましい。材質も任意である。実施上はプラスチック材又はアルミニウム材又は硬質のゴム材などが挙げられる。次ぎに足置き部材１の上面に形成されている足置き部２であるが、ここは足を乗せる箇所であり、足を乗せられる広さを有していれば良い。上面とは上側を向いた面と言うことを示し、階段状又は梯子状の下側であっても足を乗せることができる面を有していれば良い。形状は任意である。又、足置き部２は足置き部材１の一部分であるので、足置き部２を足置き部材１と云うことができる。次ぎに足置き部材１の伸縮部材取り付け部１３に取り付けられている伸縮部材３であるが、この伸縮部材３は或る長さを有した、紐状又は帯状又は鎖状の柔軟性と伸縮機能を有する部材で形成される。図１では伸縮部材取り付け部１３を棒状の部材で形成し、其処に紐状の伸縮部材３の端部を掛けた形態になっているが、伸縮部材取り付け部１３の形状は任意である。伸縮部材３は図１では上記条件を満たす部材として紐状の柔軟なゴム材を使用した形態を示している。取り付け位置及び取り付け方法は任意である。実施上、足を乗せるのに邪魔にならない箇所が好ましい。又、取り付け方法は他部材を介在させて足置き部材１に取り付けても構わない。又、柔軟性は構造で有していても材質で有していても構わない。更に伸縮機能は部材自体の材質により有していても、外部から付加されたものでも良い。付加されたものとは、例えば足置き部材１側に硬質の金属バネを取り付け、そこに或る長さと柔軟性を有する紐状又は帯状又は鎖状の部材を取り付けたような場合である。このような場合も柔軟性を有する、紐状、又は帯状又は鎖状の部材は伸縮機能を有するものと云える。実施上、伸縮部材３の寸法は太さが断面積で１ｃｍ^２程度、長さは３０ｃｍ以上を有することが好ましい。次ぎに伸縮部材３の片側先方に形成された足掛け部４であるが、これは伸縮部材３を引き伸ばす際に足先を掛けるための箇所であり、伸縮部材３の片側先方に形成された、足先を掛ける箇所を云う。図１において足掛け部４は柔軟性を有する帯状部材で形成されており、其の左右が共に直接又は間接に伸縮部材３に繋属している。それにより先端部分１４に足を掛け引いた際に伸縮部材３の張力を左右均等に受けられる構造と成っている。先端部分１４とは、足を掛けて伸縮部材３引き伸ばした際の足掛け部４の最も先方に位置する部分を云い、特にこの先端部分１４が足先を掛けて引く際に最も力の掛かる箇所となる。この部分に就いてはここを展開して平面図（ｂ）で示しているが、この幅（図面上では足掛け部４の左右端部の伸縮部材２を結ぶ線と直交する方向）が狭いと、力を加えた際に、足の先から足首に至る範囲で局所的に力が掛かる為ズレや滑りを起し易く、力を足先全体に亘り平均して掛けることができないと云う不具合が生じるのである。本発明はこの不具合を解決する為に、足掛け部４の先端部分を、長さ６ｃｍ以上に亘って、少なくとも５ｃｍ以上の幅の面を有するものとし、且つ柔軟性を有する部材を使用することで、面と柔軟性によって力を広く分散させ、ズレや滑りを防止できる様にするものである。実施上、足掛け部４の幅は１０ｃｍ程度、長さは１５ｃｍ以上で厚みは５ｍｍ以内が好ましい。孔を有していても構わない。孔を有する場合、幅は孔を含んだ寸法となる。形状は任意であり、図１では帯状の形状で示しているが、縦横がほぼ同じ寸法のシート状の部材でも良く、又其の他の形状でも良い。アニメのキャラクターの形や動物の形なども選択できる。材質も任意であり柔軟性を有していれば硬質部材と軟質部材を複合させたものでも良い。実施上は、皮材又は布材又は柔らかいプラスチック材又ビニール材又は薄いゴム板材などが好ましい。又、足掛け部４は伸縮部材３と同一部材で形成しても良く、又異なる部材で形成して伸縮部材３に繋属させた構造でも良い。図（ｃ）で示す様に板状の部材を伸縮部材３と足掛け部４の間に介在させても良く、又、図（ｄ）で示す様に伸縮部材３に紐状の部材を取り付け、そこに足掛け部４配置し環状に形成しても良い。これらの伸縮部材３と足掛け部４との間に介在し、且つ足を掛けない部材を繋ぎ部材５と云う。伸縮性を有しない繋ぎ部材５を足掛け部４の左右に取り付けた場合、足掛け部４の左右は繋ぎ部材５を介して伸縮部材３に間接に繋属していると云う。この様に間接に繋属しても図（ｃ）と（ｄ）から判る様に、伸縮部材３の張力を足掛け部４の左右に均等に掛けることができる。実施上、繋ぎ部材５を足掛け部４と伸縮部材３の間に複数介在させても構わない。又、繋ぎ部材５を、伸縮部材３と同一部材で形成した場合には繋ぎ部材５は伸縮部材３の一部となる。本発明では上記に規定した寸法以上を有し、且つ柔軟性を有する部材で形成され、且つその左右が直接又は間接に伸縮部材に繋属し、且つ足を掛けて使用できる部材は全て足掛け部４とすることができる。因って、伸縮部材３及び繋ぎ部材５も上記条件を満たせば足掛け部４とすることができる。Next, the details of each part will be described. The footrest member 1 is a pedestal for placing a foot. In FIG. 1 (a), a plate-like member is shown, but the shape is arbitrary, and it is sufficient if it has a size on which a foot can be placed. In practice, the vertical and horizontal dimensions are each preferably 10 cm or more, and the height is preferably 10 cm or less. The material is also arbitrary. In practice, a plastic material, an aluminum material, a hard rubber material, or the like is used. Next, although it is the footrest part 2 currently formed in the upper surface of the footrest member 1, this is a location on which a foot is put, and it should just have the area which can put a foot. The upper surface means a surface facing upward, and it is only necessary to have a surface on which a foot can be placed even if it is a stepped or ladder-like lower side. The shape is arbitrary. Further, since the footrest portion 2 is a part of the footrest member 1, the footrest portion 2 can be referred to as the footrest member 1. Next, it is the elastic member 3 attached to the elastic member attaching part 13 of the footrest member 1, and this elastic member 3 has a certain length, a string-like or belt-like or chain-like flexibility and an elastic function. It is formed with the member which has. In FIG. 1, the expansion / contraction member attachment portion 13 is formed of a rod-shaped member and the end of the string-like expansion / contraction member 3 is hung there, but the shape of the expansion / contraction member attachment portion 13 is arbitrary. In FIG. 1, the stretchable member 3 shows a form using a string-like flexible rubber material as a member satisfying the above conditions. The attachment position and the attachment method are arbitrary. In practice, a place that does not get in the way of putting a foot on is preferable. Moreover, you may attach to the footrest member 1 by interposing another member. Further, the flexibility may be a structure or a material. Further, the expansion / contraction function may be provided by the material of the member itself or may be added from the outside. What is added is, for example, a case where a hard metal spring is attached to the footrest member 1 side, and a string-like, belt-like or chain-like member having a certain length and flexibility is attached thereto. In such a case, it can be said that a string-like member or a band-like or chain-like member having flexibility has a stretching function. In practice, the elastic member 3 preferably has a thickness of about 1 cm ^{2 in} cross-sectional area and a length of 30 cm or more. Next, there is a footrest portion 4 formed on one side of the elastic member 3, which is a portion for hanging the foot when the elastic member 3 is stretched, and a foot formed on one side of the elastic member 3. This is the point where you hang. In FIG. 1, the footrest 4 is formed of a flexible belt-like member, and both the left and right sides thereof are directly or indirectly connected to the elastic member 3. Thus, the structure is such that the tension of the expansion / contraction member 3 can be evenly received on the left and right when the tip portion 14 is pulled. The tip portion 14 refers to a portion located at the foremost portion of the footrest portion 4 when the extensible member 3 is stretched by putting a foot on it, and in particular, a portion on which the most force is applied when the tip portion 14 is pulled on the tip of the foot. Become. This portion is expanded and shown in a plan view (b), but this width (in the drawing, the direction perpendicular to the line connecting the elastic members 2 at the left and right ends of the footrest 4) is narrow. When applying force, the force is applied locally in the range from the tip of the foot to the ankle, so there is a problem that it is easy to cause slippage and slipping, and the force cannot be applied on the entire toe on average. It happens. In the present invention, in order to solve this problem, the tip part of the footrest part 4 has a surface with a width of at least 5 cm over a length of 6 cm or more, and uses a flexible member. The surface and flexibility make it possible to widely disperse the force and prevent slippage and slippage. In practice, the footrest 4 preferably has a width of about 10 cm, a length of 15 cm or more, and a thickness of 5 mm or less. You may have a hole. When it has a hole, the width is a dimension including the hole. The shape is arbitrary, and in FIG. 1, it is shown as a band shape, but it may be a sheet-like member having substantially the same vertical and horizontal dimensions, or other shapes. You can also select the shape of an anime character or animal. The material is arbitrary, and may be a composite of a hard member and a soft member as long as it has flexibility. In practice, a skin material, a cloth material, a soft plastic material, a vinyl material, or a thin rubber plate material is preferable. The footrest 4 may be formed of the same member as the elastic member 3 or may be formed of a different member and connected to the elastic member 3. As shown in FIG. (C), a plate-like member may be interposed between the expansion / contraction member 3 and the footrest 4, and a string-like member is attached to the expansion / contraction member 3 as shown in FIG. The footrest 4 may be arranged there and formed into an annular shape. A member that is interposed between the elastic member 3 and the footrest portion 4 and that does not rest on the foot is referred to as a connecting member 5. When the connecting member 5 that does not have elasticity is attached to the left and right of the footrest 4, the left and right of the footrest 4 are said to be indirectly connected to the elastic member 3 via the connecting member 5. Even if indirectly connected in this way, the tension of the elastic member 3 can be evenly applied to the left and right of the footrest 4 as can be seen from FIGS. In practice, a plurality of connecting members 5 may be interposed between the footrest 4 and the elastic member 3. When the connecting member 5 is formed of the same member as the elastic member 3, the connecting member 5 becomes a part of the elastic member 3. In the present invention, all the members that have the dimensions defined above and are formed of a flexible member and that are directly or indirectly connected to the expansion / contraction member and that can be used by putting the foot on the footrest portion 4 are used. It can be. Therefore, if the expansion member 3 and the connecting member 5 also satisfy the above conditions, the footrest 4 can be formed.

図２は本発明の一態様に係る筋肉トレーニング器の形態の一部分を示す斜視図（ａ）と平面図（ｂ）である。図２は足掛け部４の表面に突起６を対向させて、それを左右に振り分けて形成し、板状の繋ぎ部材５を該突起６間に嵌合させて、取り付け又は取り外しができる様にした図である。この様にすると使用する際、足の大きさに対応して足掛け部４を交換することができる。実施上、足掛け部４と伸縮部材３又は繋ぎ部材５との接続方法は任意であり、多種の方法が有るが、方法は経験的に決定されて良い。 FIG. 2 is a perspective view (a) and a plan view (b) showing a part of the form of the muscle training device according to one embodiment of the present invention. In FIG. 2, the protrusion 6 is made to face the surface of the footrest portion 4 and is formed by dividing it left and right, and a plate-like connecting member 5 is fitted between the protrusions 6 so that it can be attached or removed. FIG. In this way, when used, the footrest 4 can be exchanged according to the size of the foot. In practice, the connection method between the leg rest 4 and the expansion / contraction member 3 or the connecting member 5 is arbitrary, and there are various methods, but the method may be determined empirically.

図３は本発明の一態様に係る筋肉トレーニング器の形態の一部分を示す平面図（ａ）と断面図（ｂ）である。図（ａ）は足掛け部４の内側の面、即ち足先が接触する面の中央部辺りと其の上下部分の面とを摩擦係数の異なる材質の部材で形成した図である。本態様では中央部７が其の上下部分に比べ摩擦係数の小さな部材で形成されている。は図（ｂ）はその断面図であり中央部が上下に比べ少し内側に突出している。この様にすることで使用する際、通常最も力の掛かる中央部に接触する足の皮膚を摩擦から守ることができ、足掛け部の中で足を回転させる際にもスムーズに行うことができる。中央に比して上下に摩擦係数の大きな部材を配置しているのは滑りを止めたい際に、足を上又は下の面に圧着させることにより過度の滑りを防ぐことができるからである。又、本態様において摩擦係数の大小の選択は材質面及び構造面から選択できる。材質面ではゴム材とフッ素樹脂などの対比、構造面では平面と孔と突起などの対比である。寸法を含めこれらの選択は経験的に決定されて良い。 3A and 3B are a plan view and a cross-sectional view illustrating a part of the form of the muscle training device according to the embodiment of the present invention. FIG. 4A is a diagram in which the inner surface of the footrest portion 4, that is, the central portion of the surface with which the tip of the foot contacts, and the upper and lower surfaces thereof are formed of members having different friction coefficients. In this embodiment, the central portion 7 is formed of a member having a smaller friction coefficient than the upper and lower portions thereof. Fig. (B) is a cross-sectional view thereof, with the central portion protruding slightly inward compared to the top and bottom. When used in such a manner, the skin of the foot that normally contacts the central portion where the most force is applied can be protected from friction, and when the foot is rotated in the footrest portion, it can be performed smoothly. The reason why the members having a large coefficient of friction are arranged above and below the center is that, when it is desired to stop the slipping, excessive slipping can be prevented by pressing the foot against the upper or lower surface. In this embodiment, the size of the friction coefficient can be selected from the material surface and the structure surface. In terms of material, it is a contrast between rubber material and fluororesin, and in terms of structure, it is a contrast between plane, hole and protrusion. These choices, including dimensions, can be determined empirically.

図４は本発明の一態様に係る筋肉トレーニング器の形態の一部分を示す斜視図である。図４は足掛け部４の左右両側に紐状の繋ぎ部材５を取り付けて環状を形成し、それに伸縮部材３の先端を湾曲させて接続した図である。更に繋ぎ部材５は伸縮部材３と交叉した左右を纏め合わされ、其の外側に伸縮性を有するリング状のゴム材８が取り付けられている。この構造において、リング状のゴム材８を動かすことで周長を５０ｃｍ以下とすることができ、更に其の範囲で自在に変化させることができる。周長を変化させることで、使う人が変っても、即、足の大きさに対応して周長を変更できるので、足の大きさに拘わらず、使う人に適する環を作ることができ、足掛け部４の締まり過ぎや過度の弛みに因る足からの外れを防ぐことができるのである。図４では環の形成を足掛け部４と繋ぎ部材５で成しているが、リング状の環状部材で纏め合わせて形成する環は、足掛け部４を形成する部材だけで成しても良いし、又は足掛け部４と伸縮部材３とで形成しても良い。請求項４には足掛け部の両側の部材と記しているが、これは足掛け部４を形成する部材又は繋ぎ部材５又は伸縮部材３を示すものである。 FIG. 4 is a perspective view showing a part of the form of the muscle training device according to one embodiment of the present invention. FIG. 4 is a diagram in which a string-like connecting member 5 is attached to both the left and right sides of the footrest portion 4 to form an annular shape, and the tip of the elastic member 3 is bent and connected thereto. Further, the connecting member 5 is combined with the left and right crossing with the elastic member 3, and a ring-shaped rubber material 8 having elasticity is attached to the outside thereof. In this structure, the circumference can be reduced to 50 cm or less by moving the ring-shaped rubber member 8, and can be freely changed within the range. By changing the circumference, even if the user changes, the circumference can be changed according to the size of the foot immediately, so it is possible to create a ring suitable for the user regardless of the size of the foot. Therefore, it is possible to prevent the footrest 4 from coming off from the foot due to excessive tightening or excessive slack. In FIG. 4, the ring is formed by the footrest 4 and the connecting member 5, but the ring formed by combining the ring-shaped annular members may be formed by only the member that forms the footrest 4. Alternatively, it may be formed by the footrest 4 and the elastic member 3. In claim 4, the members on both sides of the footrest portion are described, but this indicates the member that forms the footrest portion 4, the connecting member 5, or the elastic member 3.

図５は本発明の一態様に係る筋肉トレーニング器の形態を示す平面図（ａ）と側面図（ｂ）と断面図（ｃ）である。図５に示す筋肉トレーニング器は足置き部２が床面９から或る高さを有して形成されている。そして其の脇の足置き部２より低い位置に、或る広さの面を有する足擦り面１０が形成されている。伸縮部材３は足置き部材１の裏側に取り付けられており、足置き部材１の中央に形成された孔１１から外側に引き出されている。其の先方に足掛け部４が形成されている。又、足置き部材１の裏側には、取り付けられた伸縮部材３の方向を変換するための方向変換部１２が形成されている。本態様での要件は足置き部２が足擦り面１０よりも高い位置に形成されていることである。この構造により、足置き部２に片足を乗せ、もう一方の足を足掛け部４に掛けて足を動かす際、この足摺り面１０の伸長する方向に沿って足を動かすと足先を直に床に触れさせること無く動かせるので、足先で床面を擦って床面を痛めること無く使用することができる。又、足擦り面１０の表面を滑り易い部材で形成すれば足先がスムーズに滑り、足先を痛めることも防げる。本態様において足置き部材２を高い位置に形成するのは、片足を置き、もう一方の足に足掛け部材４を掛けて動かす際に動かす足の爪先を下に伸ばしても、爪先が床に触れるのを防ぐためである。実施上、足置き部４は足擦り面１０よりも５ｃｍ以上、上側に形成されていることが好ましい。足擦り］面１０の形状は任意である。実施上、幅が１０ｃｍ程度、長さは３０ｃｍ以上で平らな面を有しており、高さ床面から２ｃｍ以内程度が好ましい。材質も任意であるが、実施上、足置き部材１と同じ材質で良いが、其の他の材質、例えばシート状の薄い部材などでも構わない。又、取り外しが可能な構造にしても良い。形状及び材質は経験的に決定されて良い。又、本態様において足置き部材１の裏側に棒状の方向変換部１２を形成しているが、この方向変換部１２は伸縮部材３をこの側面に宛がい伸縮部材３の引き張る方向を変換するものである。この方向変換部１２に宛がった伸縮部材３の摩擦を減らす為に方向変換部１２に回転ローラーを取り付けても良い。又、孔１１に回転ローラーを取り付けても良い。又、本態様の筋肉トレーニング器を折り畳みができる構造にしても良い。 FIG. 5 is a plan view (a), a side view (b), and a cross-sectional view (c) showing the form of the muscle training device according to one aspect of the present invention. In the muscle training device shown in FIG. 5, the footrest 2 is formed with a certain height from the floor surface 9. And the foot-rubbed surface 10 which has a surface of a certain width is formed in the position lower than the footrest part 2 of the side. The telescopic member 3 is attached to the back side of the footrest member 1 and is drawn out from a hole 11 formed in the center of the footrest member 1. A footrest 4 is formed at the tip. Further, on the back side of the footrest member 1, a direction changing portion 12 for changing the direction of the attached elastic member 3 is formed. The requirement in this aspect is that the footrest portion 2 is formed at a position higher than the foot-rubbed surface 10. With this structure, when one foot is placed on the footrest portion 2 and the other foot is placed on the footrest portion 4 to move the foot, if the foot is moved along the direction in which the footrest surface 10 extends, Since it can be moved without touching the floor, it can be used without rubbing the floor by rubbing the floor with the tip of a foot. Moreover, if the surface of the foot rubbing surface 10 is formed of a slippery member, it is possible to prevent the toes from slipping smoothly and hurting the toes. In this embodiment, the footrest member 2 is formed at a high position because the toes touch the floor even if one foot is placed and the toe of the foot to be moved is extended downward when the footrest member 4 is hung on the other foot and moved.
