Abstract

PURPOSE:To constitute the bed so that a sick person and an old man, etc., can get on and off a floor part by himself or by only a simple help by supporting each of a waist floor side of a back floor and a foot floor side of the floor bottom so as to be turnable by a floor part supporting frame of the back floor and the waist floor, and constituting them so that they can turn, ascend and descend, respectively. CONSTITUTION:A first floor part supporting frame 3 for supporting a back floor 1 and a waist floor 2, and a second floor part supporting frame 5 for supporting a foot floor 4 are constituted so as to be attachable and detachable. In this state, the waist floor 2 side of the back floor 1 and the foot floor 4 side of the waist floor 2 are supported so as to be freely turnable, and also, ascent/descent driving mechanisms A, B of the back floor 1 and the waist floor 2 are provided on the frame 3. In such a way, this bed can be used as a usual floor plate undulation type bed, as well, and in an attitude of raising the back of a user, by detaching the frame 5, and thereafter, ringing the back floor to further turning ascent, and also, bringing the waist floor 2 to turning ascent, a raise of the use can be helped. In such a way, the user can rise to his feet easily by himself or by only a simple help of a helper by grasping a side rail, etc., of the bed.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is suitable for use in beds, especially by people who cannot get on and off the floor as freely as healthy people, such as sick or elderly people. It concerns a bed.

(Problems to be solved by conventional techniques and inventions) When a person who cannot use his/her body freely, such as a sick or elderly person, gets on and off the floor, it is difficult not only for the person but also for the caregiver. It requires a lot of effort. For example, when lowering a person who is lying on the floor on a conventional bed,
The caregiver must first lift the supine person's back into an upright cane position, then turn the patient's body so that the patient's feet are on the floor. Lifting up a sagging back can be done automatically using a conventional bed with a back floor that can be rotated and raised and lowered, but changing the orientation of the body requires care, which places a heavy burden on the caregiver.

It is an object of the present invention to solve the above-mentioned problems and to enable sick people, elderly people, etc. to get on and off the floor by themselves or with simple care.

(Means for Solving the Problems) Means for solving the above-mentioned problems will be explained with reference to drawings corresponding to embodiments. The bed of the present invention has the following features: The floor support frame 3 and the second floor support frame 5 that supports the footbed 4 are configured to be detachable, and each of the waist floor 2 side of the floor 1 and the foot seat 4 side of the waist floor 2 is attached to the first floor support frame 5. A lifting mechanism A that is rotatably supported on the floor support frame 3 and that drives the floor 1 and the waist floor 2;
B is provided on the first floor support frame 3.

(Function) The bed of the present invention constructed as described above can be used as a normal bed with a raised floor plate when the first floor support frame 3 and the second floor support frame 5 are attached and integrated. Can be used similarly. That is, Fig. 3(a), Fig. 4(
In the state shown in a), by operating the lifting drive mechanism A, the floor 1 is raised and rotated about the rotational support part f of the first floor support frame 3, and the user is placed in a back-up position. At this time, the user can lower his/her feet by operating the lifting drive mechanism B and slightly rotating and lowering the lumbar bed 2 using the rotational support part f' as a fulcrum, as shown in FIG. 3(b). It is possible to prevent the floor from being shifted in four directions.

Next, when the user gets off the bed, the second floor support frame 5 is moved to the first floor as shown in FIG. When removed from the support frame 3 and moved to a remote position, the user can put his or her feet on the floor 6 of a hospital room or the like, taking the position of sitting on a chair.

In this state, the elevating and lowering drive mechanisms A and B are operated to further rotate and raise the placing bed 1, and also to rotate and raise the waist bed 2. In this movement, the user's buttocks are lifted upward and the back is pushed forward to assist the user in standing up, as shown in Figures 3(C) and 4(d). The patient can easily stand up by himself or with simple care from a caregiver by holding on to the side rails of the bed, and can walk away from the bed.

(Example) Next, the present invention will be explained in detail.

In the embodiment, the attachment/detachment mechanism for the first floor support frame 3 and the second floor support frame 5 is provided by the respective frames 3.5.
A fitting hole 8゜8' formed adjacent to the fitting hole 8,
The mounting member 11 is provided with fitting portions 9 and 9' at both ends that can be fitted into the holder 8', respectively, and an operating knob lO.

In such a mechanism, the fitting portion 9.9' is connected to the fitting hole 8.8.
The respective frames 3.5 can be integrated in the state in which they are fitted with each other, and by removing them, the respective frames 3.5 can be separated. In addition to this configuration, any attachment/detachment mechanism may be used. Further, the second floor support frame 5 is provided with leg wheels 12 to facilitate movement, and the first floor support frame 3 is of a fixed type. Of course, the first floor support frame 3 can also be provided with leg wheels so as to be movable as required.

Next, the elevating drive mechanisms A and B attach support shafts 1 to the first floor support frame 3 corresponding to the back floor 1 and the lumbar floor 2, respectively.
3.13' is rotatably fixed, and the support shaft 13
．． A supporting arm 14, 14' and a driving arm 15, 15', which can push up the blue floor 1 and the waist floor 2, respectively, are protrudingly provided at 13'. It is constructed by connecting forward and backward drive rods 16 and 16' between the three. In addition, the support arm 14°1 on the floor 1 and the waist floor 2
A support roller 1 is provided at the location where the support is pushed up by 4'.
7.17' is provided to enable smooth operation. On the other hand, the advancing/retracting drive rod 16.16' has a screw shaft type structure, and has a movable cylinder body 18, 18' having a built-in female thread rotatably supported on the drive arm 15.15', and has one end attached to the drive arm 15.15'. A motor 20, 20' is installed on the other end side of the screw shaft 19, 19' which is screwed into the female thread. Such advance/retreat drive rods 16, 16' may also be constituted by a hydraulic cylinder device or the like. In addition to the above configuration, there is also an elevating drive mechanism A,
Although not shown in the drawings, B has a push-up arm protruding from the lower side of each of the back floor 1 and the lumbar floor 2, and has the above-described structure between each push-up arm and the first floor support frame 3. It is also possible to connect the forward and backward drive rods 16 and 16'.

Incidentally, the above-mentioned elevating and lowering drive mechanisms A and B may be constructed so as to be operated independently, respectively, but they may also be constructed so that they can be automatically associated and operated.

(Effects of the Invention) As described above, the present invention includes a first floor support frame that supports the back floor and the lumbar floor, and a second floor support frame that supports the foot floor, which are removably configured. Since each of the base end side of the floor and the footbed example of the waist floor is rotatably supported by the first floor support frame and can be rotated up and down, the first and second floor parts When the support frame is attached and the bed is integrated, it can be used in the same way as a normal bed with a raised bed, allowing the user who is lying on his/her back to sit in a raised position, with the lumbar floor being slightly lowered. This can prevent the user from shifting in the fixed depth direction.

In addition, the present invention provides the second
By removing and releasing the floor support frame, and then further rotating and lifting the back floor and rotating and lifting the lumbar floor, it is possible to assist the user in standing up. The effect is that the patient can easily stand up on his or her own or with simple care from a caregiver.
