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.

(Conventional technology and issues) When people who are unable to use their bodies, such as the sick or elderly, get on and off the floor, it requires a lot of effort not only for the person but also for the caregiver. Force. For example, when lowering a person who is lying down on the floor, the caregiver must first lift the person's back to get them up, then turn their body around and place their feet on the floor. It must be done towards the side of the section. Such lifting of the back can be performed automatically on a conventional bed with a back floor that can be rotated up and down, but changing the orientation of the body requires care, which places a heavy burden on the caregiver. Conventionally, no bed has been proposed that allows the user to easily change the orientation of the body.

The present invention aims to solve the above problems.

(Means for Solving the Problems) To explain the configuration of the present invention with reference to drawings corresponding to embodiments, the bed of the present invention first includes a floor part 2 supported above a base frame 1, a back part 2a and a bed part 2 supported above a base frame 1. The back part 2a and the waist part 2b integrally support the back part 2a so that the back part 2a can be rotated up and down, and the waist part 2b is positioned above the base frame 1. It is supported so as to be pivotable, and the foot portion 2c is supported above the base frame 1 so as to be movable up and down.

Further, the present invention provides the above-mentioned bed with a lower back portion 2b.
A swing support shaft 3 is provided projecting from the lower side of the base frame 1, and the swing support shaft 3 is rotatably supported by a swing bearing 4 projecting above the base frame 1, and the support member of the back portion 2a is attached to the swing support shaft 3. 5 to fix the back part 2a so that it can rotate up and down, and the leg parts 2c are supported above the base frame 1 via a pantograph mechanism 6 so that they can go up and down.

Further, in the present invention, in the above-described bed, the base frame 1 is provided with a support portion 7 for supporting the head side end H of the back portion 2a in a horizontal state.

(Actions and Examples) The operation of the present invention will be explained with reference to examples.

When lowering an elderly person 8 lying down on the floor 2 of the bed of the present invention from the floor 2, first lower the foot 2c as shown in FIG. Simultaneously with or in conjunction with the lowering of the back part 2a, the back part 2a is rotated and raised as shown in FIG. 1b. This action causes the elderly person 8 to lift his or her back and stand up, and assumes a posture in which the legs are supported at a lower position.

As the foot portion 2c descends, it is removed from the rotation area of the waist portion 2b, and as the back portion 2a rotates upward, the movement area of the head end H is removed from the headboard 12, so the waist portion 2b is in a state where it can rotate together with the back portion 2a without any inconvenience. becomes. Therefore, by releasing a suitable stopper (not shown) and rotating the waist part 2b together with the back part 2a, the elderly person 8 can be turned to the side of the bed in the above-mentioned position, and in this way, from above the floor part 2 You can take it down. When turning the waist portion 2b,
The caregiver only needs to help the elderly person 8 move their feet, which are supported at a lower position by lowering the foot portion 2c mentioned above, and can be lowered from there to the floor 9 of the hospital room, etc. Compared to the case where the foot 2c is suddenly lowered from the height of the foot 2c when lying on its back, the burden on both the caregiver and the elderly 8 is very light.

Next, when placing the elderly person 8 on the floor 2,
It is sufficient to perform the opposite operation to that described above, and in this case as well, the lifting of the legs necessary to change the orientation of the elderly person 8 by turning the waist portion 2b is done when the legs are supported at a low position from the floor 9 of the hospital room, etc. The burden is very light because it only extends to the foot 2c.

In the present invention, the back part 2a is integrally supported with respect to the waist part 2b so that it can rotate up and down, so it is supported by a cantilever, but the head side end H of the back part 2a in a horizontal state is supported. If the support part 7 is provided on the base frame 1, the load of the back part 2a in such a horizontal state can be supported at both ends, and the load of the back part 2a in the horizontal state can be supported.
If it is in a tilted state, the load of the elderly person 8 will move toward the waist 2a side, so even cantilever support will not work.

Next, the rotation of the waist portion 2b position is achieved by, for example, providing a rotation support shaft 3 protruding from the lower side of the waist portion 2b, and supporting the rotation support shaft 3 so as to be able to rotate on a rotation bearing 4 protruding from above the base frame 1. In addition, the back part 2a is provided with a support member 5 for the back part 2a on the pivot support shaft 3, and is supported by the support member 5 so as to be rotatable up and down.
b, and can rotate. In the illustrated example, the mechanism for rotating and raising and lowering the back part 2a is constructed by connecting a connecting arm 10 protruding from the support member 5 and an elastic rod 11 such as a gas spring between a suitable position on the head side of the back part 2a. ing. In addition to the above-mentioned configuration, a pivoting mechanism at the waist 2b position, an operating mechanism for enabling or disabling pivoting, and a support mechanism for the back 2a are appropriate. Further, the foot portion 2c can be raised and lowered by, for example, supporting the foot portion 2c above the front and rear base frame 1 via the pantograph mechanism 6, but any other appropriate raising and lowering mechanism may be applied. be able to. In addition to the parallel elevation using the pantograph mechanism 6 or the like, the ascending and descending mode may be arbitrary, such as a mode in which only the waist portion 2b side is elevated. Further, in such an elevating mechanism, a mechanism that supports the foot portion 2c at an upper position and a lower position is also suitable.

(Effects of the Invention) As described above, the bed of the present invention is constructed by dividing the floor part supported above the base frame into a back part, a waist part, and a foot part, and the back part and the waist part are
The back part is integrally supported so that it can be rotated up and down, the waist position is supported so as to be pivotable above the base frame, and the legs are supported so that it can be raised and lowered above the base frame. This has the effect that people who are unable to use their bodies as they wish, such as the elderly, can change the orientation of their bodies, which is necessary when getting on and off the floor, with a very light burden.
