The picture of the state). Further, Fig. 5 is a view showing a state in which the leg plate 9 is most located on the foot side (L side) (that is, a state in which the distance between the head plate 8 and the leg plate 9 is the longest in the bed device 1). Further, Fig. 6 is a view showing the intermediate state in the fourth and fifth figures.

Here, the leg receiving portion 90 provided with the leg plate 9 is movably configured by the bed device 1 (foot frame portion 28b), the slide mechanism 400, and the link mechanism. The link mechanism in the present embodiment is mainly composed of the link 102 and the link 104, and includes a rotating shaft or the like.

The lower end of the link 102 is pivoted to the lower end of the electric actuator 36 (the end of the piston rod 36a) around the fulcrum 202, and the upper end thereof is fixed by the fulcrum 204. Further, the link 102 is connected to the link 104 with the rotation shaft 300 interposed around the fulcrum 204.

The rotating shaft 300, at the fulcrum 204, is spanned between a pair of links 104 and coupled to the connecting rod 104. And fixed to the connecting rod 102 in the middle of the rotating shaft 300.

The link 104 is formed in a pair on the left and right sides in the width direction of the leg plate 9 (the leg receiving portion 90), and the lower end thereof is rotatably coupled to the rotating shaft 300 around the fulcrum 204 to be coupled to the link 102. Further, the support member 408 provided at a lower portion of the foot frame portion 28b is rotatably coupled to the foot frame portion 28b.

Further, the link 104 has a long hole 206 formed on the upper side. In the long hole 206, the protruding portion 410 provided to the leg receiving portion 90 is movably inserted therein.

The slide mechanism 400 is a mechanism for moving the leg plate 9 to the front and rear. Specifically, the support member 402 is coupled to the leg receiving portion 90, and the support member 402 is provided with a roller portion 404.

Here, since the electric actuator 36 is a well-known object, the detailed description thereof will be omitted. In outline, the motor is incorporated therein, and the piston rod 36a is advanced from the cylinder by the forward and reverse rotation of the motor. Or back. Further, the electric actuator 36 is controlled by the control box 40. The operation signal is input to the control box 40 by the user inputting an operation signal via the operation unit. Then, it is input as a control signal to the electric actuator 36, and the piston rod is moved forward (stretched) or retracted (retracted) by the motor action. Thereby, the movement operation of the leg plate 9 is performed.

In this way, a motor for advancing or retracting the piston rod 36a is integrally formed on the driving side, and an operation hole is formed at the end portion on the driving side, and the operation hole is used for the operation of the power failure. The end of the operating shaft of the crank is fitted, and the piston rod can be rotated.

[1.3 Action of the foot plate drive mechanism]

Next, the operation of the leg drive mechanism will be described. For example, in the state shown in FIG. 4, the user inputs an operation of moving the foot plate via the operation unit or the like. When this is done, the electric actuator 36 is driven to retract the piston rod 36a.

When the piston rod 36a is retracted, the link 102 is rotated in the clockwise direction as the piston rod 36a moves backward. Further, the link 104 coupled to the link 102 is also rotated in the clockwise direction.

When the link 104 is rotated, the leg receiving portion 90, the protruding portion 410 receives the force acting in the clockwise direction by the link 104, and moves the leg receiving portion 90 toward the foot side (L side). Here, since the distance between the fulcrum 204 and the protruding portion 410 is shortened due to the movement of the leg receiving portion 90 toward the foot side, the protruding portion 410 moves downward in the long hole 206.

Then, in the state of Fig. 6 (the link 102 and the link 104 are in a vertical state), since the distance between the fulcrum 204 and the protruding portion 410 becomes the shortest, the protruding portion 410 becomes positioned on the lower side of the long hole 206. .

Further, by the piston rod 36a being further retracted, the distance between the fulcrum 204 and the protruding portion 410 is again expanded, and the protruding portion 410 is moved upward in the elongated hole 206. Further, in the state of FIG. 5, the protruding portion 410 is positioned on the upper side of the long hole 206.

Further, the leg plate 9 (the leg receiving portion 90) is horizontally slidably moved on the sole plate 28 (foot frame portion 28b) by the slide mechanism 400. Thereby, for example, even if the sole plate 28 is tilted, the sole plate 28 and the leg plate 9 can be moved at a predetermined angle (for example, in a vertical state in the case of the present embodiment).

As described above, according to the present embodiment, regardless of the position where the footrest 28 is located, the user can move the foot plate 9 in response to the user. Thereby, for example, regardless of the tilting operation state of the footrest 28, the sole of the user can be brought into contact with the sole.

The connecting member 504 is a pair of right and left sides in the width direction of the leg receiving portion 90, and is a member for connecting the leg receiving portion 90 (foot plate 9) and the toe frame portion 28b.

The connecting member 504 is formed with a long hole 506 in the vertical direction so that the protruding portion 508 inserted along the long hole 506 can move up and down. With the connection member 504, the leg plate 9 can be moved while the play of the foot plate 9 is loosened (swaying in the vertical direction), and the leg plate 9 can be moved.

Further, as shown in Fig. 9, when the leg plate 9 is most located on the head side (H side), the protruding portion 508 is positioned below the long hole 506. When the foot plate 9 moves toward the foot side (L side), the protruding portion 508 moves over the long hole 506, and then is in the state of FIG. 11 (the link 502 is perpendicular to the foot bottom plate 28). The top position. Then, when the foot plate 9 moves further toward the foot side, the protruding portion 508 moves downward again in the long hole 506, and when the foot plate 9 moves to the most foot side (L side), the protruding portion 508 is positioned in the long hole. Below 506.

Fig. 13 is a view showing a state in which the leg plate 9 is most located on the head side (H side) (that is, a state in which the distance between the head plate 8 and the leg plate 9 is the shortest in the bed device 1). Further, Fig. 14 is a view showing a state in which the leg plate 9 is most located on the foot side (L side) (that is, a state in which the distance between the head plate 8 and the leg plate 9 is the longest in the bed device 1).

In the present embodiment, the leg plate 9 (the leg receiving portion 90) is configured to be movable by the slide mechanism 600. Here, the roller portion 604 provided on the support member 602 is a roller provided with a lock mechanism.

Specifically, the roller portion 604 is provided to be movable to the guide member 606, and is movable in the front-rear direction (the direction of the arrow P10 in FIG. 13), and can be locked (fixed) at an arbitrary position. Therefore, the user or the care receiver can move the foot board 9 to an arbitrary position, whereby the foot board 9 can be fixed at the position conforming to the user's body type.

Further, the slide mechanism 600 of the present embodiment may be configured such that the leg plate 9 can be fixed at any position. For example, a plurality of holes (recesses) or a leg receiving portion 90 may be provided in the foot frame portion 28b. The lower portion is provided with a configuration of a convex portion and the like.

In this case, the position of the leg plate 9 can be fixed at any position by fitting the convex portion provided at the lower portion of the leg receiving portion 90 to the hole portion at any position of the foot frame portion 28b.
