Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is suitable for use by a bed, particularly a person who cannot freely get on and off the floor like a healthy person, such as a sick person and an elderly person. It is related to a sleeper.

(Problems to be Solved by Conventional Techniques and Inventions) When a person, such as a sick person or an elderly person, who does not have the physical freedom as he / she intends to get on / off the floor, not only the person himself / herself but also the caregiver It takes a great deal of effort. For example, when dropping a person lying on the floor in a conventional ordinary bed, the caregiver first lifts the back of the person who is lying down and stands up, and then turns the body. Must be changed and the foot should be directed to the side of the floor. The back can be lifted automatically even with a conventional bed in which the back bed can be rotated and raised and lowered, but care is required to change the direction of the body, which imposes a heavy burden on the caregiver.

It is an object of the present invention to solve the above problems and enable a sick person, an elderly person, etc. to get on and off a floor by himself or by only simple care.

(Means for Solving the Problems) The means for solving the above problems will be described with reference to the drawings corresponding to the embodiments. A bed according to the present invention includes a first bed that supports a back bed 1 and a waist bed 2. Floor support frame 3
And the second floor support frame 5 for supporting the foot floor 4 is detachably configured, and the waist floor 2 side portion f of the back floor 1 and the foot floor 4 side portion f'of the waist floor 2 are rotatably supported. As a part, the first floor support frame 3 is independently rotatably supported, and the back floor 1 and the leg floor 2 are independently rotated with the rotation support portions f and f'as fulcrums. Elevating drive mechanisms A and B are provided on the first floor support frame 3.

(Operation) In the bed of the present invention configured as described above, in the state in which the first floor support frame 3 and the second floor support frame 5 are attached and integrated, a normal floor board raising type bed is provided. Can be used as well. That is, by operating the lifting drive mechanism A in the state shown in FIGS. 3 (a) and 4 (a), the back floor 1 is fulcrumed on the rotation support portion f of the first floor support frame 3. As shown in FIG.
As shown in (b), when the waist floor 2 is slightly rotated and lowered with the rotation support portion f ′ as a fulcrum, the waist floor 2 is inclined with the back floor 1 side downward, so that the user moves in the direction of the foot floor 4 direction. It can be prevented from being displaced.

Next, when the user gets off the bed, the second floor support frame 5 is moved to the first floor as shown in FIG. 4 (c) while the back bed 1 is appropriately rotated and raised. Floor support frame 3
When it is removed from and moved to a position away from the user, the user can put his / her foot on the floor 6 such as a patient's room, and is in a posture of sitting on a chair.

In this state, the lift drive mechanisms A and B are operated to operate the back bed 1
Is further rotated and raised, and the waist floor 2 is also rotated and raised so that the back floor 1 side is inclined upward. In this operation, the user lifts the buttocks upward and pushes his back forward as shown in FIG. 3 (c) and FIG. 4 (d), which assists the user in standing up. You can easily stand up by yourself by holding it on the side rail 7 of the bed, or just by the caregiver's simple care.
You can walk away from the bed.

(Example) Next, the Example of this invention is described.

In the embodiment, the attachment / detachment mechanism for the first floor support frame 3 and the second floor support frame 5 includes fitting holes 8 and 8 ′ formed in adjacent portions of the respective frames 3 and 5, and Fitting portions 9 and 9'that can be fitted into the fitting holes 8 and 8'are provided at both ends, and a mounting member 11 provided with an operating knob portion 10 is provided.
In such a mechanism, the respective frames 3 and 5 can be integrated with the fitting portions 9 and 9'fitted into the fitting holes 8 and 8 ', and by removing these, Each frame 3,
5 can be separated. In addition to this configuration, the attachment / detachment mechanism is appropriate. Also, the second floor support frame 5 is a leg wheel.
12 is provided to facilitate movement, and the first floor support frame 3 is fixed. Of course, the first floor support frame 3 can also be provided with leg wheels so that it can be moved as necessary.

Next, the lifting drive mechanisms A and B are connected to the first floor support frame 3
And support shafts 13 and 13 'corresponding to the back 1 and waist 2 respectively.
Support arms 14 and 14 'which can be rotatably fixed and can push up the back floor 1 and the waist floor 2 on the support shafts 13 and 13', respectively.
And driving arms 15 and 15 'are provided in a protruding manner, and the respective driving arms 15 and 15' are configured by connecting advancing and retracting driving rods 16 and 16 'between the first floor supporting frames 3. Further, support rollers 17, 17 'are provided at the portions of the back floor 1 and the waist floor 2 that are pushed up and supported by the support arms 14, 14' to enable smooth operation. On the other hand, the advancing / retreating drive rods 16 and 16 'have a screw shaft type structure, and rotatably support the movable cylinders 18 and 18' having internal threads inside the drive arms 15 and 15 ', and one end side thereof is Motors 20 and 20 'are mounted on the other ends of screw shafts 19 and 19' which are screwed into female threads. Such forward / backward drive rod 16,16 ′
Can also be composed of a hydraulic cylinder device or the like. Also,
In addition to the above configuration, although not shown in the drawings, the lifting drive mechanisms A and B have push-up arms projecting below the back floor 1 and the waist floor 2, respectively, and the push-up arms and the first It is also possible to connect the advancing and retracting drive rods 16 and 16 'as described above between the floor supporting frames 3.

The lifting drive mechanisms A and B described above may be configured to operate independently, but may also be configured to be automatically associated and operable.

(Effects of the Invention) As described above, the present invention is configured such that the first floor support frame that supports the back floor and the lumbar floor and the second floor support frame that supports the foot floor are detachably configured, and Since each of the waist floor side portion of the floor and the foot floor side portion of the waist floor is independently and rotatably supported on the first floor supporting frame as a rotation supporting portion, the structure is configured so that they can be respectively rotated and raised and lowered. , With the first and second floor support frames attached to each other and being used in the same manner as a normal floor board upright bed, a supine user can be placed in a back-up posture. It is possible to prevent the user from shifting in the footbed direction by lowering the waist floor slightly and inclining the back floor side downward at this time. Further, in the present invention, in the above-described back-raising posture, the second floor support frame is removed and released, and then the back floor is further rotated and raised, and the waist floor is also rotated and raised, and the back floor is raised. By tilting the side upwards, it is possible to assist the user in standing up, so that the user can easily stand up by himself / herself by the side rails of the bed or by the caregiver's simple care. There is an effect that can be.
