PROBLEM TO BE SOLVED: To provide a leg device to be worn on a leg of a user to support the motion of the leg, while reducing time and effort for wearing.SOLUTION: The thigh link 20 of the leg device 10 includes a thigh front frame 22 and a curved supporting plate 28. The thigh front frame 22 extends from one side of the knee to the other side of the knee through the thigh front side, and both ends of the thigh front frame 22 are rockably connected with a crus link 50 at the side of each knee. One end of the curved supporting plate 28 is rotatably connected with the thigh front frame 22 on one side of the thigh. At the same time, the curved supporting plate 28 includes a fastener 26 which is engaged with/disengaged from the thigh front frame 22 at the other side of the thigh on the other end, and is placed along the approximately half circumference of the thigh on the rear side of the thigh. On the curved supporting plate 28, a cam lever 25 which extends from one end to the rear side of the thigh front frame 22 is installed. When the thigh link 20 is fitted, the cam lever 25 is pressed to the thigh front surface as the thigh front frame 22 approaches the thigh front surface of the user. As a result, the curved supporting plate 28 passively turns in a direction to approach the thigh rear surface.COPYRIGHT: (C)2012,JPO&INPIT【課題】装着する手間を低減した脚装具を提供する。【解決手段】脚装具10の大腿リンク20は、大腿前フレーム22、湾曲支持板28を備える。大腿前フレーム22は、膝の一方の側方から大腿前側を通って膝の他方の側方へと伸びており、両端が夫々膝の側方で下腿リンク50と揺動可能に連結している。湾曲支持板28は、一端が大腿の一方の側方で大腿前フレーム22と回転可能に連結しているとともに、他端に大腿の他方の側方で大腿前フレーム22と係合離脱する留具26を有しており、大腿の裏側略半周に亘ってあてがわれる。湾曲支持板28、その一端から大腿前フレーム22の裏側に向かって伸びるカムレバー25が設けられている。大腿リンク20を装着する際、大腿前フレーム22をユーザの大腿前面に接近させるにつれてカムレバー25が大腿前面に押圧される。その結果、湾曲支持板28が大腿裏面へ近づく方向に受動的に回動する。【選択図】図4
