JPS5816742Y2 - Toilet opening formation mechanism in bed with toilet bowl - Google Patents

Description

[Detailed description of the invention] This invention is a bed with a toilet bowl that allows bedridden elderly people, critically ill patients, etc. to defecate while lying supine on the bed.
The present invention relates to an opening forming mechanism that allows a very rational opening for a toilet bowl to be formed.

As a method to allow the patient to defecate while lying on a bed (or supine or sitting up) without moving the patient as much as possible,
There is a method in which the toilet bowl is normally stored below the floorboard and raised when in use, but with this method, an opening that communicates with the toilet bowl must be formed in the part of the mattress corresponding to the patient's lower back, that is, the urination area.

Methods of forming an opening in the pinerest part include a method in which the opening is formed by horizontally sliding the waist pinerest, which has conventionally been divided into sections, and a method in which the opening is formed in a pinetress with an opening formed in advance. There is a method in which a pine tress paradra is loaded and the pine tress pad is moved downward during defecation to form an opening, but in the former method, the patient's lower back is moved by the sliding of the pine tress, causing discomfort. Moreover, the latter method has the disadvantage that it takes too much time to set the toilet bowl in a predetermined position.

The present invention consists of a lumbar manodress that is divided into left and right parts of the pinerest corresponding to the patient's floor, and each lumbar pinerest is folded downward from the split end side, thereby creating an opening for the toilet bowl. By forming
The opening can be formed quickly and without causing any discomfort to the patient.In particular, the proposed new method supports each of the lumbar pinerests in an extremely rational manner. The opening has a sufficient width, and when the opening is not formed, the lumbar mattress can be well supported, so the sleeping comfort is not deteriorated.

Hereinafter, the present invention will be explained in detail based on examples.

Reference numeral 1 denotes a pinerest, which is composed of lumbar pinerests 2.2', which are divided into left and right parts of the lumbar region of the pinerest 1.

Each of the lumbar pinerests 2, 2' is attached to the floor support frame 3 of the bed.
a support 4 configured to be movable and expandable in the lateral direction of the
Support at 4'.

The supports 4, 4' may have a structure as described later, as long as they can be moved in the lateral direction of the floor support frame 3 and can be expanded and contracted.

Below the supports 4, 4' are actuating bodies 5, 5' which are movable in the lateral direction of the floor support frame 3.

Split ends a, a of the husband's waist pinerests 2, 2'
/ side (while fixing the strips 6, 6', support rollers 7, 7' are lined up at the split ends a'N of the respective supports 4, 4'G). Said operating body 5
, 5'G are provided with actuating rollers 8, 8', and the strips 6, 6' are wound around the actuating rollers 8, 8' through the lower part of the support roller 7, 7', respectively, and their edges are b and b' are fixed in place on the floor support frame 3.

The actuating bodies 5, 5' are configured to move the supporting bodies 4, 4' by engaging the divided ends a, a' in the force direction.

Here, the concrete example shown in the figure of the supports 4, 4' is such that a base frame is constructed by connecting a plurality of frame bars 10 to which guide wheels 9 are attached at both ends, and the support roller 7 is attached to one side of the base frame. When the extension frame rod 11 is attached, the extension frame rod 11 with the guide ring 9 on the other side is attached telescopically, and a compression spring 12 is interposed between the extension frame rod 11 and the base frame, and the extension frame rod 10 and the extension frame rod 10 are attached. Although the guide wheels 9 provided at both ends of the frame rod 11 are attached to the guide frame 13, the example shown in FIG. In addition to the frame-like configuration, it may also be plate-shaped, and its moving mechanism and expansion/contraction mechanism may be configured as appropriate.

In this configuration, when the actuating body 5 on the right side in the figure is moved to the right by any appropriate drive mechanism, the actuating roller 8
pulls the strip 6 to the right, but since its end edge is fixed to the floor support frame 3, the first operating roller 8 is rotated by the strip 6 and pulls the split end a side of the strip 6. to move.

At this time, the actuating roller 8 acts like a moving pulley on the strip 6, so that the strip 6 moves twice as far as the moving distance of the actuating roller 8.

Accordingly, the split end a side of the waist mattress 2 is pulled by the band-like body 6 and folded downward.

At this time, the support body 4 of the main part pinerest 2 receives a force in the right direction in the figure by the part of the waist part pinerest 2 that is folded in, but since the support body 4 engages with the actuating body 5 in this direction, The moving distance is equal to that of the actuating roller 8, and therefore, the folded portion of the waist mattress 2 is supported by the support roller 7 provided on the split end a side of the support body 4 while the folded portion of the waist mattress 2 is moved by the actuating roller 8. (Gradually move to the right.

When the support body 4 moves in this way, its right end comes into contact with the floor support frame 3, but since the support body 4 is configured to be expandable and contractible in the width direction of the floor support body 3, the right end thereof comes into contact with the floor support frame 3. The split end a side can be moved rightward to the shortening limit, that is, the folded portion of the waist pinerest 2 can also be moved rightward to the shortening limit.

By performing the above operation for the lumbar pinerest 2' on the left side of the figure, an opening O is formed at the divided end a y a''fUU of the lumbar pinerest 2, 2' corresponding to the patient's excretion area.
Thereafter, the toilet bowl 14 is raised from below the floor support 3 by an appropriate mechanism and protruded from the opening O, allowing the patient to defecate.

In such a case, the present invention provides support 4 for the lumbar pinerests 2, 2'.
, 4' are movable in the lateral direction of the floor support frame 3, and are also extendable and contractible in the same direction. The degree of freedom of the structure can be adjusted to that of a dog, and it is possible to prevent defecation from adhering to the lumbar pinerests 2, 2'.

Next, after defecation, when the actuating bodies 5, 5' are moved in the opposite direction, the supports 4, 4' engage with the actuating bodies 5, 5', and the divided ends a p a' (1! Because it can be moved to I.

The lumbar pinerests 2, 2' return to their original state due to the pressing force of the support rollers 7, 7' and their own restoring force.
The patient will be in a normal supine position without any problems.

The supports 4, 4' move as described above (tangle and then stretch again), and support the lumbar pinerests 2, 2' as a whole, so they are comfortable to sleep on. The lumbar mattresses 2, 2' can be well supported as a whole, and no large gaps are formed on the edge side of the floor support frame 3, so there is no fear of feet falling when getting on or off the bed.

It is desirable, but not necessary, that the supports 5, 5' be biased in the direction of extension by a spring such as the compression spring 12 of the embodiment.

The mechanism for moving the actuating bodies 5, 5' as described above, as shown in the figure, uses a common endless annular transmission link 15 provided over the movement range of each of the actuating bodies 5, 5'. In addition to a mechanism that moves the actuating bodies 5, 5' in conjunction with each other in the opposite direction or backward direction, any mechanism may be used to interlock the actuating bodies 5, 5'. ′ may be moved individually.

As described above, the present invention consists of a lumbar pinerest that corresponds to the patient's lower back, which is divided into left and right parts, and each lumbar pinerest is folded downward from the divided end side to form an opening for a toilet bowl. Therefore, the opening can be formed quickly (and without causing any discomfort to the patient).

In particular, in the present invention, the support body of the lumbar pinerest is configured to be movable in the lateral direction of the floor support frame and extendable, so that the width of the opening can be made sufficient. A major feature is that the lumbar pinerest can be well supported even when no opening is formed.
