尚、本実施形態では各足掛止部４ａ，４ｂに架け渡す帯体１６の本数を３本としているが、これは様々な使用者Ｕの体格の差を考慮したものであり、従って、帯体１６を架け渡す本数については設計者側で適宜変更される。 First, the foot-holding portions 4a and 4b are formed by bridging the longitudinal and three strips 16, 16, and 16 on the edge of a frame having a through hole 21 in the center. The ankle is hooked on one of the bands 16, 16, and 16 that matches the body shape of the user U, and the feet Fa and Fb do not escape due to the entanglement of the band 16. Hold on. Further, on the left and right edges of the through holes 21 of the foot-holding portions 4a and 4b, rod-shaped handles 5a and 5b extending forward are pivotally supported in a state where they can be rotated forward and backward. In addition, at the distal ends of the handles 5a and 5b, a vast rubber grip 24 is provided so that the user U can easily grip it with the hands Ka and Kb. Although not shown in the drawings, coil springs connected to the support plate 6 are provided on the rear side of the foot latching portions 4a and 4b, respectively, and pulled when the user U extends his / her foot tips Fa and Fb. An urging force of the coil spring is applied in the direction to perform an auxiliary function when the handles 5a and 5b are pushed out.
In the present embodiment, the number of the belt bodies 16 to be bridged between the leg latching portions 4a and 4b is three. However, this is because the difference in the physique of various users U is taken into account. The number over which the body 16 is bridged is appropriately changed on the designer side.

次に、支持板６において各足掛止部４ａ，４ｂを前後動させる機能部分について説明する。
まず各足掛止部４ａ，４ｂと支持板６の間には図２（ａ）（ｂ）及び図３（ａ）（ｂ）のように、各足掛止部４ａ，４ｂ底面側の前後に延長したブロック状をなす上支持体７を備える一方、支持板６の天面側における前記上支持体７との対応箇所には、同じくブロック状をなす下支持体８を備えている。そして上支持体７の下面側と下支持体８の上面側には、断面凹溝状の上下各ガイド穴１０ａ，１０ｂをそれぞれ設けており、さらに上下各ガイド穴１０ａ，１０ｂ間には球体９が介在し、この球体９の転がりによって支持板６からの各足掛止部４ａ，４ｂの前後方向へのスライドを可能としている。 Next, the function part which moves each leg latch part 4a, 4b back and forth in the support plate 6 is demonstrated.
First, as shown in FIGS. 2 (a), 2 (b) and 3 (a), (b), the front and rear sides of the foot retaining portions 4a, 4b are arranged between the foot retaining portions 4a, 4b and the support plate 6, respectively. On the other hand, a block-like lower support 8 is provided at a position corresponding to the upper support 7 on the top surface side of the support plate 6. Further, upper and lower guide holes 10a and 10b each having a concave groove shape are provided on the lower surface side of the upper support 7 and the upper surface side of the lower support 8, and a sphere 9 is provided between the upper and lower guide holes 10a and 10b. With the ball 9 rolling, the leg latching portions 4a and 4b can be slid in the front-rear direction from the support plate 6.

そして前述した上下各支持体７，８の左右側には図３（ｂ）のように、支持板６天面側の前後（図中では左右に）に間隔をあけた２箇所において起立部材１１，１１をそれぞれ設けてあり、さらに各起立部材１１，１１間には、規制部材１２が架け渡してある。一方、各足掛止部４ａ，４ｂの各々の底面側には図２（ｂ）のように、前記規制部材１２を挟むように２枚の垂下部材１３，１３が各々配設してあり、さらに前記各垂下部材１３，１３の下端部間には縦に回転するローラー１４を軸支し、各足掛止部４ａ，４ｂの下面側も含めて規制部材１２を囲む状態となっている。
尚、上下各支持体７，８と規制部材１２との間隔は、前記ローラー１４及び垂下部材１３，１３が互いに干渉することのない位置関係にあり、これにより各足掛止部４ａ，４ｂは、支持板６上において前後方向へのスムーズなスライドが可能となる。 Further, on the left and right sides of the above-described upper and lower supports 7 and 8, as shown in FIG. 11 are provided, and a regulating member 12 is bridged between the standing members 11 and 11. On the other hand, as shown in FIG. 2 (b), two hanging members 13 and 13 are disposed on the bottom side of each of the foot-holding portions 4a and 4b so as to sandwich the regulating member 12, respectively. Further, a vertically rotating roller 14 is pivotally supported between the lower end portions of the hanging members 13 and 13 so as to surround the regulating member 12 including the lower surface sides of the leg latching portions 4a and 4b.
Note that the distance between the upper and lower supports 7 and 8 and the regulating member 12 is such that the roller 14 and the hanging members 13 and 13 do not interfere with each other. Smooth sliding in the front-rear direction on the support plate 6 is possible.

次に各ハンドル５ａ，５ｂは、長手の金属棒の先端部にゴム製の握り２４を備えたものである。そして前記ハンドル５ａ，５ｂの基端側は、対応する各足掛止部４ａ，４ｂの外側面に各々ピン３１ａ，３１ｂ止めされており、このピン３１ａ，３１ｂを軸として各ハンドル５ａ，５ｂが縦回転させられるようになっており、使用時において使用者Ｕの手Ｋａ，Ｋｂの動きに対応するしくみになっている。また各ハンドル５ａ，５ｂは、背板１の両側縁にそれぞれ備えた各ストッパー２８ａ，２８ｂに係止でき、これにより本身体伸張器具の未使用時において、各ハンドル５ａ，５ｂが不用意に回転することがなくなる（図１参照）。 Next, each handle 5a, 5b is provided with a rubber grip 24 at the tip of a long metal rod. And the base end side of the said handles 5a and 5b is each pin 31a, 31b fixed to the outer surface of each corresponding leg latching part 4a, 4b, and each handle 5a, 5b is centered on this pin 31a, 31b. It is designed to be rotated in the vertical direction, and corresponds to the movement of the user Ka's hands Ka and Kb during use. The handles 5a and 5b can be locked to the stoppers 28a and 28b provided on both side edges of the back plate 1, so that the handles 5a and 5b rotate carelessly when the body stretching device is not used. (See FIG. 1).

図４（ａ）（ｂ）は、頭側固定部２と背板１との連結部分を拡大したものである。背板１側にはフック状の金具１９ａが備えてあり、また頭側固定部２と足側固定部３には、前述したフック状金具１９ａと係合可能な受金具１９ｂが備わっており、本身体伸張器具を構成する各部１，２，３間の使用時における不意な離脱が防がれているとともに、未使用時には容易に脱着でき、本身体伸張器具の持ち運びや設置時の省スペース化に考慮してある。
尚、背板１と足側固定部３との連結も、上記した頭側固定部２と背板１との連結状態と同一のものであるから、ここでは説明を省略した。 4A and 4B are enlarged views of the connecting portion between the head side fixing portion 2 and the back plate 1. A hook-shaped metal fitting 19a is provided on the back plate 1 side, and the head-side fixing portion 2 and the foot-side fixing portion 3 are provided with a receiving metal fitting 19b that can be engaged with the hook-shaped metal fitting 19a. Unintentional detachment between the parts 1, 2, and 3 constituting the body stretching device is prevented, and it can be easily detached when not in use, saving space when carrying and installing the body stretching device. Is taken into account.
Since the connection between the back plate 1 and the foot side fixing portion 3 is the same as the connection state between the head side fixing portion 2 and the back plate 1 described above, the description is omitted here.

以上のように形成した本身体伸張器具を実際に使用する際には図５に示すように、まず使用者Ｕが頭側固定部２、背板１、そして足側固定部３に跨って横たわり、顎Ｈにマスク２３をかけた状態で頭部固定部２のバンド２２により頭を保持する一方、両足先Ｆａ，Ｆｂを対応する各足掛止部４ａ，４ｂの帯体１６にそれぞれ引っ掛け、当該各足掛止部４ａ，４ｂから各々延長するハンドル５ａ，５ｂを握って使用前の初期位置につく。次に、各足掛止部４ａ，４ｂ間の連結金具１５の可動片２６を突起２５から外し、当該各足掛止部４ａ，４ｂが個々に前後動可能な状態にあることを確認した後、任意のハンドル５ａ，５ｂを押し出すような操作を行う。これにより使用者Ｕの一方の足先Ｆａ，Ｆｂが伸ばされると共に、例えば両足先Ｆａ，Ｆｂを保持する位置を左右相違する状態で設定できる等、様々な体型の使用者Ｕに対応した使用が可能となる。また両足先Ｆａ，Ｆｂを同時に伸ばしたい場合には図６（ａ）（ｂ）のように、前記連結金具１５の可動片２６の通し孔２７に、足掛止部４ｂから上方に突出する突起２５を差し込んでロック状態とすることで、各足掛止部４ａ，４ｂが一体化する。これにより両側の各ハンドル５ａ，５ｂ、又は片側のハンドル５ａ，５ｂのみを押し出すことで、各足掛止部４ａ，４ｂが同時に支持板６から前後にスライドし、従来ある身体伸張器具のような使い方も可能となる。 When actually using the body stretching device formed as described above, as shown in FIG. 5, first, the user U lies across the head side fixing portion 2, the back plate 1, and the foot side fixing portion 3. , While holding the head with the band 22 of the head fixing portion 2 with the mask 23 on the jaw H, the feet Fa and Fb are respectively hooked on the band bodies 16 of the corresponding foot latch portions 4a and 4b, The handles 5a and 5b extending from the respective foot-holding portions 4a and 4b are gripped to reach an initial position before use. Next, after removing the movable piece 26 of the connecting bracket 15 between the respective leg latching portions 4a and 4b from the projection 25, it is confirmed that the respective leg latching portions 4a and 4b are individually movable back and forth. Then, an operation for pushing out the arbitrary handles 5a and 5b is performed. As a result, one of the user's U's toes Fa and Fb is extended, and for example, the positions for holding both the toes Fa and Fb can be set in different states. It becomes possible. When it is desired to extend both foot tips Fa and Fb at the same time, as shown in FIGS. By inserting 25 into the locked state, the leg latching portions 4a and 4b are integrated. As a result, by pushing out only the handles 5a and 5b on both sides or only the handles 5a and 5b on one side, the foot-holding portions 4a and 4b are simultaneously slid forward and backward from the support plate 6, and like a conventional body stretching device. Usage is also possible.

図７と図８（ａ）（ｂ）に示すものは、本身体伸張器具に腰揺動部を備えたものである。
この腰揺動部は図に示すように、使用者Ｕの腰掛ける座板３３と中板３４と底板３５を上下に三段に重ねており、さらに座板３３の中央には、臀部の大きさに対応した受孔３７が空き、その受孔３７には無端状をなす腰掛用の帯体３９が架け渡してある。
