[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Nursing care bed B shown in FIGS.
Has a bed body 1 and a movable bed body 2. The bed body 1 will be described. Bed body 1
Is composed of a first side floor section 3, a second side floor section 4, a head section 5, a foot section 6, and a storage section space section 7. As shown in FIG. 2, the first side floor portion 3 is formed to be bent inward in a plane L-shape, and the inside is a storage space 7 (see FIG. 7). Both end portions of the first side floor portion 3 are stepped portions 5 a of the head portion 5.
And are mounted on and fixed to the step 6a of the foot portion 6, respectively. According to the illustrated example, the head section 5 and the foot section 6 each include boards 5b and 6b and storage box sections 5c and 6c below the boards. Each storage box part 5
c, 6c can be opened and closed by doors 5c1, 6c1. The second side floor portion 4 is arranged on the opening side of the storage space portion 7 with the movable bed body 2 interposed therebetween. The second side floor portion 4 is formed in a flat plate shape as shown in FIGS. 2 and 3. Both end portions of the second side floor portion 4 are detachably held from the step portions 5a, 6a of the head portion 5 and the foot portion 6, respectively. In the example shown in the figure, the positioning projections 4 projecting from the back surfaces at both ends of the second side floor 4 serve as position holding means.
a, 4b and positioning recesses 5c2, 6c2 formed in the step portions 5a, 6a and fitted with the above-mentioned convex portions.
Therefore, if the second side floor is lifted upward from the state of attachment of the second side floor 4 in FIGS. 2 and 3, the second side floor 4 can easily be detached from the head 5 and the foot 6. The upper surface of the second side floor 4 is flush with that of the first side floor 3. The movable bed 2 will be described with reference to FIGS. 1, 2, 5 and 6. Floor 8, carriage 9, drive 10 and support 11
And has the function of a wheelchair. The floor 8 is supported on the carriage 9 at the center of the lower surface. The upper surface of the floor 8 is flush with the upper surfaces of the first side floor 3 and the second side floor 4, and the floor together with the first side floor and the second side floor is the floor of the nursing bed. Is formed. The floor 8 has a backrest 8b on the left side in FIG. 1 and a leg support 8c on the right side of the seat 8a. Both the backrest 8b and the leg support 8c can be raised and lowered (rotatable) with the end on the side of the seat 8a as a base point (FIG. 5). Armrests 12 can be attached to both ends of the seat 8a. 8a1 is a mounting hole for the armrest 12 provided on the seat 8a. A support leg 11, which is a support, is attached to the lower surface of the backrest 8b. The support leg 11 is rotatable about a pin 11a at one end. When rotated from the horizontal storage state shown in FIG. 2 by 90 °, its tip comes into contact with the floor on which the nursing bed is installed, and has a function of keeping the floor 8 horizontal. The caster unit 9 has a caster 13 attached to the bottom thereof. A push handle 14 is provided at the rear of the carriage 9.
Is provided. This hand push handle serves as an operation handle of the bogie unit 9 and is pulled upward during use. The drive unit 10 is attached to the bogie unit 9. The drive unit 10 has an operation mechanism for raising and lowering the backrest 8b and the leg support 8c. In the example of FIG. 1, the operation mechanism is mainly composed of a first cylinder 15 and a second cylinder 16. The first cylinder 15 and the second cylinder 16 are both supported rotatably about shafts 17 and 18 provided in the bogie unit 9, and are operated by an operation panel 19. The first cylinder 15 is connected at its tip to the lower surface of the backrest 8b. The second cylinder 16 is connected to the lower surface of the leg support 8c. The rod 1 is driven by the driving of the first cylinder 15.
5a expands and contracts, and the backrest portion 8b rotates about the base point and is raised and lowered. Similarly, the rod 16a expands and contracts by the driving of the second cylinder 16, and the leg support 8c rotates about the base point to be undulated. The movable bed 2 is disposed in a storage space 7 facing the inside of the first side floor 3, and can be moved out of the bed main body 1 from the storage space 7 as needed. . Next, a method of using the nursing bed B will be described. The case where the entire nursing care bed is used will be described. In this case, as shown in FIGS. 2 and 3,
The movable bed body 2 is arranged in the storage space 7 of the bed body 1 to form a nursing bed B. In this state, the care receiver can be laid on the nursing bed B, and the bed functions as expected. At this time, nursing bed B
Although not shown on both sides of FIG. 2, a fall prevention fence is attached. A case in which a care receiver prone on the nursing bed B is moved will be described. In this case, the movable bed 2 is used as a wheelchair. For this purpose, the caregiver first lifts the second side floor 4 off the nursing bed B as shown by the chain line in FIG. Then, the seat 8a
Attach armrests 12 on both sides. Then, movable bed 2
Is moved downward by the cart 9 in FIG.
Pull out outside. Thereafter, the first cylinder 15 is driven to raise the backrest portion 8b, and the second cylinder 16 is driven to tilt the leg support portion 8c to the state shown in FIG. In this state, the care receiver on the floor 8 is raised up while sitting on the seat 8a. As described above, not only can the user eat and change clothes while the upper body is raised on the floor portion 8, but also the family can enjoy conversation with the family and watching TV. At this time, if the care receiver is tired or wants to lie down, the first and second cylinders 15 and 16 are driven to bring the backrest 8b and the leg support 8c to a horizontal state as shown in FIG. Then, the support 11 is rotated to stand on the installation floor. In this way, the care receiver can sleep on the floor 8 on the spot. In order to return the movable bed body 2 to the original position, the movable bed body 2 is moved to the storage space section 7 using the carriage section 9, and the second side floor section 4 may be placed on the steps 5a, 6a. First and second floors 3,
It is not always necessary to provide a step portion in the head portion 5 and the foot portion 6 of FIG. In this case, the first side floor part 3, the head part 5 and the foot part 6 are mutually connected, and the second side floor part 4 is temporarily fixed to the head part 5 and the foot part 6 instead of the step part. Position holding means is provided. The operation mechanism of the drive unit 10 is not limited to the cylinder mechanism as shown in the figure, but may be constituted by, for example, a link mechanism in which a nut is combined with a threaded rod and a link is connected to the nut. Providing the support portion 11 has an advantage that the load on the drive portion 10 can be reduced when the floor portion 8 of the movable bed body 2 is set in a horizontal state when used as a wheelchair. It is not essential.

[0007]

According to the present invention, since the movable bed body having the function of a wheelchair forms a part of the nursing bed, the care receiver can move while lying down or with the upper body up. The caregiver can be laid on the spot at the destination, reducing the caregiver's burden of caregiving, and the caregiver can be cared for without being isolated from their family members. You can ask.
