のである。(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention connects the back body, the lumbar floor, and the first and second legs to each other by hinges,
The back bed is supported on the bed frame via a back stop mechanism, and the back bed has one end pivoted to the back body, and a back support that abuts and holds the back body forms a part. , the other end of which is supported on the bed frame via a frame provided with a rotating member that abuts the waist floor; The second leg floor is pivoted and supported by the other end.
The l end is hingedly supported on the first leg floor of No. 111, and a rotating member is provided on the other end, and the back body and the waist floor are raised and lowered by the back stop mechanism, and the link rod is used to raise and lower the back body and the lumbar floor. 11. The first leg bed and the second leg bed are bent under the bed frame.
また、本発明は、腰床に、前記フレームの他端部の回動
部材を介して前記フレームを支持案内する案内枠を設け
るものである。Further, in the present invention, a guide frame is provided on the waist floor to support and guide the frame via a rotating member at the other end of the frame.
また、本発明は、第２脚床に設けられた回動部材は前記
背体および腰床の起伏動作に連動して、床に接触し転動
するものである。Further, in the present invention, the rotating member provided on the second leg floor comes into contact with the floor and rolls in conjunction with the up-and-down motion of the back body and the lumbar floor.
（作用） 本発明によれば、先ず、背止げ機構を駆動する。(effect) According to the present invention, first, the back stop mechanism is driven.
背体は起伏し、これに伴って前記背体に軸着される連動
杆はへラドボード側に引き込まれ、これによって前記連
動杆は第１脚床をベッド枠体下方向に屈曲させる。The back body rises and falls, and as a result, the interlocking rod pivoted to the back body is retracted toward the helad board, whereby the interlocking rod bends the first leg floor downwardly of the bed frame.

。The first leg bed is bent toward the floor together with the second leg bed, and the rotating member of the second leg bed is in contact with the floor. Further, when the first leg floor is bent, since the second leg floor is hinged to the first leg floor, the first leg floor and the second leg floor are bent, and the rotating member rolls on the floor. As you do so, you will be drawn towards the headboard.

。Next, when the back stop mechanism continues to be driven, the interlocking rod is further displaced as the back body rises and falls. In addition, with the undulation of the back,
The frame rotates clockwise, thereby raising the waist floor and slightly displacing it in the direction of the floor making. For this reason, although the waist floor is raised and lowered, the contact position between the waist floor in 1111 and the frame shifts due to the fact that the rotating member provided on the frame in 11j rolls on the guide frame of the waist floor. , Ii'
1. While the floor and frame are in contact with each other, the back body and lumbar floor can be smoothly raised and lowered without interfering with each other's movements.

When the start-up continues, the interlocking rod 28 is further displaced as the back pressure 4 rises and falls. Further, the frame 23, which is pivoted to the fulcrum 22 of the support rod II of the side frame 2 by 1'15 to the ups and downs of the back pressure 4, rotates clockwise around the fulcrum 22, and thereby the leg floor S is It rises and is displaced towards the Wakasensoku floor. Therefore, as the leg floor 5 is raised and lowered, the contact position between the leg floor 5 and the frame 23 shifts. Since the frame 27 is rolled, the leg floor 5 and the frame 23 are in contact with each other and do not interfere with each other's movement, so that the back pressure 4 and the leg floor 5 can be smoothly raised and lowered.

能となる効果も奏する。(Effects of the Invention) According to the present invention, first, the first leg bed is bent in the downward direction of the bed frame body by the interlocking rod pivoted on the back bed while increasing the back pressure, and then the back pressure is raised and lowered. If you continue to drive the lifter (14), the interlocking rod will further displace as the back pressure rises and falls.In addition, as the back pressure rises and falls, the leg floor also rises, so the patient can easily get into a standing position. Therefore, the effort of changing the patient's body position and moving it becomes unnecessary, and it becomes possible to eliminate the heavy burden and burden placed on the caregiver and the patient. However, since the target can be achieved only with the back raising mechanism 7, it is possible to simplify I>i +yy, simplify the production of T and ■, and reduce costs.
