2. Description of the Related Art Recent beds are often provided with a floor raising / lowering mechanism, and a user can lie in a desired posture by raising their back and legs.

[0003]

However, in order to raise the back and legs, the floor 1 is divided into a plurality of parts so that the floor 1 can be bent. If it does not fit the user's waist and joints, the body parts other than the waist and joints will be supported at the bent parts 2 and 3, and in extreme cases, the bent part 3 of the floor 1 will hit the calf, The lower limbs are raised, and the comfort is impaired (see FIG. 10). The present invention has been proposed in order to improve the above-described disadvantages, and the bent position of the floor can be adjusted so that the bent portion of the floor can be applied to the user's body regardless of the user's physique. It is an object of the present invention to provide a mechanism for adjusting a bent position of a floor in a bed provided with a floor undulating mechanism, which can be adapted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a description will be given of an embodiment of a floor bending position adjusting mechanism in a bed provided with a floor undulating mechanism according to the present invention with reference to the accompanying drawings. FIG.
2 shows a floor 10 in a bed provided with a floor undulating mechanism. The floor 10 is divided into a knee bed 11 corresponding to a knee and a leg floor 12 corresponding to a leg, and near both end faces in the width direction of the floor 10. , A leg-raising mechanism (not shown) is provided so as to be flexibly connected by a first hinge 13 so that the knee bed 11 and the leg floor 12 are interlockedly raised and lowered. The knee bed 11 includes first and second knee beds 11a,
The floor 10 is divided by a second hinge 14 so as to be bendable in the vicinity of both end faces in the width direction.

[0007] Of the first and second knee beds 11a and 11b, a second hinge bed 11b adjacent to the leg bed 12 is selectively connected to a first hinge 13 and a second hinge 14 which are connection points. A slide shaft 15 is provided as a selective restraint mechanism for restraining the second knee bed 11b with one of the adjacent first knee bed 11a or one of the leg floors 12.

[0010] As shown in FIG. 3, the slide shaft body 15 includes first and second knee floors 11 a and 11 b and a foot floor 12 near the first hinge 13 and the second hinge 14 in the second knee floor 11 b. A movable shaft 17 movably inserted into a bearing 16 provided inside a notch (described later) formed on the opposite end face of the movable shaft 17;
A pair of support shafts 18a, 1
8b. The movable shaft 17 is at least
When penetrating the first knee bed 11a and the second knee bed 11b, the ends must be separated from the cutouts of the leg bed 12 while the second knee bed 11b and the leg bed 12 are penetrated. The end is set to a size separated from the notch of the first knee bed 11a. One of the movable shafts 17 is rotatably mounted on a pair of support shafts 18a and 18b via connecting pipes 19a and 19b, and is used to prevent the movable shaft 17 from coming off in a radial direction. (See FIG. 4). Further, an operation lever 21 for rotating the movable shaft 17 around the axis with respect to the connecting pipes 19a and 19b is implanted at the center of the movable shaft 17. The operation lever 21 is connected to the second knee bed 11b.
The projection 10 protrudes from the substantially U-shaped guide groove 22 formed on the end face in the width direction of the floor portion 10 and is movable along the guide groove 22 (see FIG. 2).

As shown in FIG. 5, a bearing 16 for inserting the movable shaft 17 of the slide shaft body 15 is
1b, the first knee bed 11a and the first
The hinge 13 and the second hinge 14 are provided inside a notch 23 formed near the end face where the hinge 13 and the second hinge 14 are provided. The notch 23 has a mounting edge 2 of the bearing 16 formed by being folded inward.
4a and 24b are provided. The bearing 16 is made of PO
M is made of a self-lubricating, high-strength engineering plastic such as M. An insertion hole 16a having a size corresponding to the outer diameter of the movable shaft 17 is formed at the center, and is screwed to a mounting edge 24 in the cutout portion 23 on both sides. And a fixing frame 16b. In addition, at positions where both ends of the movable shaft 17 are provided on the first knee bed 11a and the leg floor 12, the bearing 16 is mounted upside down on the back side of the upper surface of the first knee floor 11a and the leg floor 12 (FIG. 6). reference).

In the floor unit 10 having the above-structured floor undulating mechanism, the first and second knee beds 11a and 11b and the legs are provided at the joints behind the user's knees according to the user's physique. The position of the first hinge 13 or the second hinge 14 connecting the floor 12 is adjusted to be provided. That is, the operation lever 21 of the slide shaft 15 moves the slide shaft 15 along the guide groove 22 to the guide groove 22.
To reach both ends. Then, the end of the movable shaft 17 reaches the first knee floor 11a or the bearing 16 on the leg floor 12.

When the end of the movable shaft 17 reaches the bearing 16 on the side of the first knee bed 11a, the second hinge 14 for connecting the first knee bed 11a and the second knee bed 11b is restrained. The other end of the movable shaft 17 is detached from the cutout portion 23 on the end surface of the leg floor 12 where the first hinge 13 is provided, so that the first hinge 13 is in a free state, and when the leg raising mechanism is moved, The first knee bed 11a, the second knee floor 11b, and the leg floor 12 move up and down in an interlocking manner with the first hinge 13 connecting the second knee floor 11b and the leg floor 12 being bent points (FIGS. 7, 9).
reference).

On the other hand, when the end of the movable shaft 17 reaches the bearing 16 on the footbed 12, the first hinge 13 connecting the second knee floor 11b and the footbed 12 is restrained while the movable shaft 17 is held. Is separated from the notch 23 in the end face of the first knee bed 11a, so that the second hinge 14 is in a free state. When the leg raising mechanism is moved, the first knee bed 11a and the second knee bed 11b are moved. Knee joint 11a, second knee bed 11b, and footbed 1 with the second hinge 14 connecting the
2 are linked up and down (see FIG. 8). As described above, the bent portion can be switched and adjusted according to the user's physique, and the operation method is simple, so that a bed excellent in usability can be provided.

[0013]

As described above, according to the present invention, the bent position of the floor can be adjusted with a simple structure and good operability regardless of the physique of the user. Can be adapted to the body of the user, and it can be said that the bed is excellent in usability.
