Description

[Detailed Description of the Invention] The present invention relates to a support mechanism for a floorboard in a bed.

Today, as the population ages and the number of nuclear families progresses, when a sick person becomes bedridden, a designated small number of family members must provide care, and toilets are often done using toilets. However, when using a toilet on a regular bed or futon, the caregiver lifts the patient's waist and inserts the toilet under the patient's buttocks, and then lifts the patient's waist again and pulls out the toilet. They are forced to perform extremely hard labor. It is also painful for sick people to relieve themselves with a hard, thick toilet bowl pushed under their buttocks and their hips lifted.

The present invention has a structure in which the floorboard is divided into a back floorboard, a lumbar back floorboard, and a foot floorboard, and these are rationally linked, and the lumbar floorboard is configured to be able to be raised and lowered, thereby reducing the labor of the caregiver when using the toilet. This reduces the burden and allows sick people to relieve themselves without pain. The present invention will be described in detail below based on examples.

Reference numeral 1 denotes a back floor plate, and the back floor plate 1 is rotatably supported by a floor plate support frame 3 at a location 2 appropriately away from the waist side end toward the head side. Reference numeral 4 is an example of such support, and is a support arm. Reference numeral 5 denotes a lumbar floor plate, and the lumbar floor plate 5 is supported on a lumbar support frame 6 so as to be movable up and down. The elevating mechanism may be any appropriate one, such as a cross-linked parallel movement mechanism as shown in the drawings, and the drive mechanism thereof may be an electric motor, manual, or other appropriate mechanism. The foot side of the waist support frame 6 is rotatably supported by the floorboard support frame 3. In the embodiment shown in FIGS. 1 and 2, a support arm 7 is provided protruding from the leg side of the lumbar support frame 6, and the upper part of the support arm 7 is
It is rotatably fixed to the end of the foot floor plate 8 fixed to the floor plate support frame 3, and the foot side of the waist support frame 6 is rotatably supported above the floor plate support frame 3. In the other embodiment shown in FIG. 3, the foot floor plate 8 is rotatably supported on the floor plate support frame 3 at a lower position than in the previous example without intervening. As described above, the position and method of fixing the leg side of the lumbar support frame 6 is appropriate as long as it is rotatably supported. Therefore, the head side of the lumbar support frame 6 and the back floor plate 1
A support link 9 is connected between the rotation fulcrum, that is, the waist side of the point 2. Then, a foot floor plate 8 is fixed to the floor plate support frame 3 on the side adjacent to the waist floor plate 5. Reference numerals 10, 11, and 12 designate cushion members such as pinerests that are fixed to the back floor plate 1, waist floor plate 5, and foot floor plate 8 by appropriate methods.

In this configuration, when a sick person lying supine on a bed has an urge to defecate, the lumbar floor plate 5 is first lowered. In this way, a gap is created between the patient's buttocks and the corresponding pinerest 11, so the toilet bowl can be easily installed in the specified position with little effort, and it is also less painful for the patient because the toilet bowl is not forced into it. . When the back floor plate 1 is rotated upward and the back is appropriately lifted, the sick person is kept in a sitting position on the toilet rather than in a high posture as in the past, making it easier to defecate. After defecating, lower the back floor plate 1 and lower the lumbar floor plate 5,
In this way, the toilet bowl can be easily taken out. After taking out the toilet bowl, the lumbar floor plate 5 can be raised again to return to the normal supine position. In the above explanation, the back floor plate 1 is raised after the toilet is inserted and lowered before the toilet is taken out, but conversely, even if the toilet is inserted and taken out when the back floor plate 1 is raised. Of course it's a good thing.

Next, the mechanism of the present invention for raising and lowering the back floor plate 1 will be explained as follows. That is, the back floorboard 1
by an appropriate drive mechanism (including an electric motor, gas spring 13, etc., as well as a human-powered mechanism).
When the lumbar support frame is rotated upward using the fulcrum as a rotational fulcrum, the lumbar side end moves downward, and the support link 9 is pushed down, so that the lumbar support frame moves upward at the foot side point 14.
The lumbar floor plate 5 rotates downward using the lumbar floor plate 5 as a rotation fulcrum.
It also rotates and descends. At this time, the lumbar side end of the back floor plate 1 and the back side end of the lumbar floor plate 5 descend using the respective dorsal points 2 and 14 as pivot points.
Each moves away from the other by descending. In this way, when the back floorboard 1 is rotated and raised, the pinerests 10 and 11 are separated from each other, so it is possible to effectively prevent them from interfering with each other and being displaced or deformed.
Another feature is that the back floor plate 1 can be rotated up and down and the waist floor plate 5 can be raised and lowered smoothly. In particular, the support of the leg side of the lumbar support frame 6 is shown in FIGS. 1 and 2.
In the case of the upper position as in the embodiment shown in the figure, the lumbar floor plate 5 is separated from the back floor plate 1 by a longer distance, so even if thick pine braces 10, 11, and 12 are used, there will be no interference as described above. It has characteristics. Furthermore, in the present invention, as the back floor plate 1 rises, the lumbar support frame 6, and hence the lumbar floor plate 5, tilts upward toward the feet. It has the characteristics of being able to prevent damage and being comfortable to sit on.

As described above, the present invention includes rotatably supporting the foot side of the lumbar support frame that supports the lumbar floor plate upwardly and movably up and down on the floor plate support frame, and the back side and the lumbar part of the lumbar support frame that Since the sides are connected by support links and interlocked, the rotational elevation of the back floor plate and the elevation of the lumbar floor plate can be done rationally without interference, thereby reducing the labor burden on caregivers when using the toilet. The major feature of this method is that it can significantly reduce the amount of stress experienced by patients, and also allows sick people to relieve themselves without pain. Furthermore, the present invention has the feature that it can be used as a bed with a raised floor plate that is comfortable to sit on even in normal use.
