PROBLEM TO BE SOLVED: To select an optimal position and an optimal force transmission state by changing a pulling position in improving the lower limb for bending and stretching the knee.SOLUTION: A slide base 4 is reciprocated along slide grooves 2 of a base 1, and a tilting plate 6 is turnably erected at the center of the slide base 4 by hinges 7. A footrest part 12 is mounted in a laterally turnable and vertically reciprocating manner to the surface of the tilting plate 6 through an elongated hole 11, a bolt 14 and a nut 15. One end of each of traction strings 22 are connected to right and left connection holes 21 of the tilting plate 6, and grip parts 24 at the other end of each of the traction strings 22 are pulled or loosened to reciprocate the footrest part 12 together with the tilting plate 6. The knee is thereby bent and stretched to improve the lower limb. An optimal part for bending and stretching the lower limb is selected by switching the connection holes 21 to which the one end of each of the traction strings 22 are connected, and a part for making improvement preponderantly is switched between the heel, arch and toes of the foot.COPYRIGHT: (C)2012,JPO&INPIT【課題】膝の屈伸及び伸長を行う下肢の改善で、牽引位置を変えて、最適な位置、最適な力の伝達状態を選択する。【解決手段】基台1のスライド溝2に沿ってスライド台4が往復動され、このスライド台4の中央に傾動板6が蝶番7で回動可能に起立され、この傾動板6の表面に長穴11、ボルト14及びナット15で足当部12が左右に回動可能及び上下に往復動可能に取り付けられる。傾動板6の左右の連結穴21…に牽引紐22…の一端が結ばれ、この牽引紐22…の他端の握り部24を引いたり緩めたりし、傾動板6とともに足当部12が往復動し、膝が屈伸及び伸長され下肢が改善される。牽引紐22…の一端が連結される連結穴21…を切り換えると、下肢の屈伸及び伸長を行うのに、最適な個所が選ばれ、改善を重点的に行う部分をかかと、土踏まず、つま先とで切り換えられる。【選択図】図1
