<p><P>PROBLEM TO BE SOLVED: To solve the problem that a conventional supporting mechanism which can set the supporting position for the foot bottom end section at high and low positions under a state wherein the knee bottom is raised enables the setting from the high position to the low position, not to be performed unless the knee bottom is raised, and also that the setting is released when the knee bottom is lowered, next to keep the setting changed to the high position. <P>SOLUTION: One end side of the knee bottom 2 is turnably and elevatably supported by a bed frame 1, and one end side of the foot bottom 6 is turnably connected with the other end side of the knee bottom 2. A supporting stay 7 is turnably connected with the lower side of the other end side of the foot bottom, and the supporting means 11 of a supporting section 9 which is constituted on the distal end side of the supporting stay 7 is constituted on the bed frame. The supporting means is constituted of a guide section 12 which movably supports the supporting section of the supporting stay, and an engaging section 13. The guide section is constituted in a manner to be supportable the supporting section which moves accompanying the turning while covering the turning range of the knee bottom. While, the engaging section is constituted on the top or the bottom of the end section side of the guide section where the supporting section is located when the knee bottom is lowered. The problem is solved in this manner. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
