DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the care bed of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a floor frame, which is composed of a back frame 11, a seat frame 12, a lower leg frame 13, and a foot frame 14, and these frames 11
Are arranged in order from the head side to the foot side.

The ends of the back frame 11 and the seat frame 12, the ends of the seat frame 12 and the lower leg frame 13, and the ends of the lower leg frame 13 and the foot frame 14 are hinge portions. The floor frames 1 are connected by hinges 15A, 15B, and 15C so that the floor frame 1 can be bent by four.

FIG. 7 is a sectional view of the hinge portions 15A to 15C. That is, a connecting portion 15b having a bolt insertion hole 15a is formed at an end of each of the frames 11 to 14, and the connecting portion 15b of each of the frames 11, 12 is formed.
The bolts 15 are inserted into each bolt insertion hole 15a.
c is inserted, and a nut 15e is screwed into a screw portion 15d of the bolt 15c.

Mats 111 to 114 are attached to the frames 11 to 14 of the floor frame body 1, respectively.

Reference numeral 2 denotes a support for the floor frame 1, from which legs 2A extend.

Reference numeral 3 denotes a rotation mechanism which uses the motor M1 as a drive source, and rotates the lower leg frame 13 and the foot frame 14 by the rod 31 and the links 32 and 33.

The motor M1 is pivotally attached to a bearing 2B formed on the support 2 by a horizontal pin 2C, and a drive shaft 34 of the motor M1 is formed with an external thread 34a. A screw hole 31a opening on the base end side of the rod 31 is formed in the rod 31 so as to be coaxial with the rod 31, and this screw hole 31a is screwed into a male screw portion 33a of the drive shaft 34, and is connected to the drive shaft 34. The rod 31 is connected so as to be coaxial.

Link portions 32a and 32b are protruded from an intermediate portion and a lower end portion of the link 32, and an upper end of the link 32 has a connecting piece 2 formed on a lower surface of a head end of the support 2 at a lower end portion of the support end.
D is pivotally connected to the horizontal pin P1, and the distal end of the rod 31 is pivotally connected to the connecting portion 32a by the horizontal pin P2. Bolt insertion holes 32c and 33c are formed in the connecting portions 32a and 32b of the links 32 and 33, respectively.

As shown in FIG. 3, the link 32 (33) and the foot frame 14 are hinged (connecting means) H1 (H2).
At the pivot. That is, the connecting piece 14c having the bolt insertion hole 14b is formed in the cross member 14a of the foot frame 14.
(FIG. 2), and the connecting piece 14c and the link 32 are provided.
(33), the bolts 22 are inserted into the bolt insertion holes 14b, 32c (33c), and the nuts 24 are screwed into the threaded portions 23 of the bolts 22 to form the hinge H1 ( H2) is configured (FIG. 9).

Reference numeral 4 denotes a rotation mechanism which uses the motor M2 as a drive source, and rotates the back frame 11 and the seat frame 12 by the rod 41 and the pair of links 42.

The motor M2 is pivotally mounted on a bearing 2E formed on the support 2 by a horizontal pin 2F, and a drive shaft 44 of the motor M2 is formed with a male screw portion 44a. A screw hole 31a opening on the base end side of the rod 41 is formed in the rod 31 so as to be coaxial with the rod 31, and this screw hole 41a is screwed into a male screw portion 43a of the drive shaft 44 to form a drive shaft. 44 and the rod 41 are connected so as to be coaxial.

A pair of links 42 are connected by a cross member 41A, from which a connecting piece 41B protrudes, and the connecting piece 41B and the tip of the rod 31 are connected to a horizontal pin P.
It is pivoted at 4.

A pair of rollers R supported by a support member R1 is attached to the back of the back frame 11 on the rear side of the cross member 11a. This roller R is in rolling contact with the link 42 (FIG. 1).
0). C is a cover that covers the roller R and the link 41.

The seat frame 12 of the floor frame 1 is pivotally connected to the support 2 by a hinge (connecting means) H4 (FIG. 4). That is, a connecting portion 12c having a bolt insertion hole 12b protrudes from the cross member 11a of the seat frame 12, while a bolt insertion hole 21 is formed from the end of the head of the support 2.
a connecting portion 21 having a
c, 21 are overlapped with each other, and the bolt insertion holes 21a, 12b
The hinge H3 is formed by inserting a bolt 22 through the nut 22 and screwing a nut 24 into a screw portion 23 of the bolt 22 (FIG. 8).

FIG. 2 shows a state in which the floor frame 1 is separated from the support 2. That is, the hinge (connection means) H
The nuts 24 of H1, H2 and H4 are removed from the bolt 22, and the bolt 22 is removed from the bolt insertion holes 21a.
The link 41 is removed from the cover C. Floor frame 1
When attaching to the support 2, the reverse operation may be performed. Thus, the floor frame 1 and the support 2 can be separated during transportation or storage.

The floor frame 1 can be attached to and detached from the support 2 whether it is flat or folded as shown in FIG.

A flush toilet B is provided below the seat frame 12, and a valve seat B is provided on the seat frame 12.
1 and a seat mat 11 corresponding to the valve seat
2 is configured to be removable.

The operation of the care bed constructed as described above will be described. First, by rotating the motor M2 of the rotation drive mechanism unit 4 forward and pulling the rod 41 to raise the link 41, the head of the seat frame 12 is centered on the hinge H4 as shown by a two-dot chain line in FIG. The rear frame 11 pivots upward about the hinge 15 while the roll R rolls on the link 41 while the rib end pivots downward.

On the other hand, when the motor M1 of the rotation drive mechanism unit 3 is rotated forward to pull the rod 43 and rotate the links 32, 33, the hinges H1, H2, H2,
15A and 15B rotate, and the lower leg frame 13 rotates in the hanging direction. Then, with the crus frame 13 hanging down, the foot frame 14 is bent at substantially 90 degrees with respect to the crus frame 13.

As described above, the floor frame 1 is deformed into a four-folded state, so that the patient can sit down. That is, while the buttocks and thighs of the patient are positioned on the seat frame 12, the patient's head and trunk are
The patient's lower leg can be bent by the lower leg frame 13 and the patient's foot can be brought into contact with the mat of the foot frame. As a result, the patient can easily stand up on the foot frame.

Further, since the seat frame 12 is slightly inclined, the buttocks of the patient are less likely to move forward. As a result, a stable sitting posture can be ensured even if the back frame stands upright. it can.

Further, when the back frame 11 is raised up to the vertical direction, the center of gravity of the patient can be moved forward, and the movement of the standing posture can be reduced. On the other hand, if the lower leg frame 13 is hung vertically, it becomes easier to step on when shifting from the sitting posture to the standing posture, and the center of gravity can be moved smoothly.

When the motors M 1 and M 2 of the rotation drive mechanism units 3 and 4 are reversed to project the rod 41, as shown by the solid lines in FIG. 4, the back frame 11, the seat frame, the lower leg frame 13, and the foot The section frames 14 are horizontally positioned at the same level, and the lying down is possible.

[0030]

As is clear from the above description, according to the nursing bed of the present invention, the folding frame body can be separated from the support, so that it can be easily transported and stored.
