Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a toilet bowl used in a patient's bed.

<Prior Art> Conventionally, various structures have been used as toilet bowls in beds for patients with this type of illness. For example, there is a patient's bed B' as shown in FIG. 10, which employs a well-known Japanese-style toilet bowl A' used by healthy people.
However, in this patient's bed B', the toilet bowl A' can be set in the excretion port 1' opened in the laying mat b1' after lowering the waist mat 2' that opens and closes the excretion port 1'. must be moved to a position directly below the excretion port 1' and raised to prevent excrement from scattering outside. In other words, once the waist pine 2'
A step of lowering the toilet A' to below the excretion port 1' via the pantograph mechanism 40, a step of moving the horizontally moving frame 42 via the drive device 41 so that the toilet bowl A' is located directly below the excretion port 1', The three steps of raising the toilet bowl A' and positioning it in the excretion port 1' have to be carried out continuously but separately, so it takes a considerable amount of time to set up the toilet bowl A', making it difficult to defecate. The company had a problem that could not be quickly addressed.

Therefore, as shown in FIG. 9, the applicant pivoted the upper end of the link c1 back and forth at a predetermined interval on both left and right sides of the lower surface of the waist mat 2 that opens and closes the excretion port 1, and the lower ends of the links c1 are connected to each other. The connecting rod 14 is connected to the laying mat b1, and the connecting rod 14 is slidably fitted to a guide rail c2 provided across the front and back direction of the laying mat b1, and the connecting rod 14 is connected to the laying mat b1.
1. A reciprocating belt body c provided in the lower front-rear direction.
3, and a guide hole c4 is installed to slidably guide the pivot point at the upper end of the link c1 in order to change the link c1 from an upright state to a laid down state as the belt body c3 reciprocates.
1, and the guide hole c4 is formed under the arc-shaped hole portion 24.
and a horizontal hole 25 continuous to the lower end of the arc-shaped hole 24, and a toilet A' is fixedly provided below the excretion port 1, and the ball part a1' of the toilet A' and the laying mat An excretion cover 3 having a vertical opening between the excretion cover 3 and the guide rail c2 is slidably fitted and disposed between the excretion cover 3 and the guide rail c2. By rotating the belt body c3 of the opening/closing device C provided on the belt body c3 in one direction, the waist mat 2 opens the excretion port 1 by lowering the link c1 using the guide hole c4 as a guide. At the same time as the opening operation is performed, the excretion cover 3 is horizontally moved directly below the excretion port 1 by the pusher part c5 fixed to the belt body c3 in succession to the opening operation (double-dotted chain line), thereby preventing excrement from scattering to the outside. Similarly, between the excretion port 1 and the bowl part a of the toilet bowl A'
1', and was developed to be able to quickly respond to the act of defecating.

However, as the belt body c3 moves in the opposite direction after defecating, the link c1 rises using the guide hole c4 as a guide, and the waist mat 2 closes the excretion port 1. During the movement of the toilet cover 3, especially the toilet bowl.
During the movement of A' from the top of the ball part a1' and during the waiting period after returning to the original position, excrement adhering to the inner surface falls (drops) onto the floor D. I realized that there is a risk of contamination.

<Problems to be solved by the invention> The problems to be solved by the invention are not only to be able to quickly deal with defecation, but also to be able to handle the excretion cover horizontally after defecating. To provide a toilet bowl which can surely receive excrement adhering to its inner surface during waiting after returning to its original position at a bowl part without dropping (dripping) onto the floor surface.

<Means for Solving the Problems> The technical means taken by the present invention to solve the above problems is to move the waist mat directly below the excretion opening in succession to the opening operation of the waist mat that opens and closes the excretion opening, An excretion cover that connects the excretion opening and the bowl part of the toilet bowl and is moved back to its original position continuously with the closing operation of the waist mat, is operated in a series of continuous operations through the opening/closing operation of the waist mat and the opening/closing device. The patient's bed is constructed by being connected and installed at the lower part of the bed, and the ball part of the toilet main body is extended in the opposite direction to the opening direction of the defecation port, so that the opening shape of the ball part is horizontally elongated in plan. This is because it is formed into a rectangular shape.

<Function> In this invention, the bowl part of the toilet bowl is formed into a horizontally long rectangular shape in a plane that spans the entire movement range of the excretion cover that moves parallel to the opening/closing operation of the waist mat that opens and closes the excretion opening. The bowl portion of the toilet bowl is positioned under the excretion cover not only inside, but also during the horizontal movement of the excretion cover after defecating, and while waiting after returning to its original position.

<Example> An example of the present invention will be described based on the drawings.
The toilet main body A has a defecation port A2 and a water supply port A3 opening in the same direction on one side of the ball portion A1, and a flow path A4 through which cleaning water flows inside the opening edge of the ball portion A1, A rim part a6 with a large number of blow-off holes a5... is formed at an arbitrary location on the bottom wall of the flow path a4, and the ball part a1 extends in the opposite direction to the opening direction of the defecation port a2. At least the opening shape of the ball portion a1 is formed into a horizontally long rectangular shape in plan view.

The opening length in the longitudinal direction of the ball part a1 is arranged under the laying mat b1 so that it operates continuously with the opening and closing operation of the waist mat 2 which opens and closes the excretion port 1 opened in the laying mat b1 of the patient's bed B. It is formed to extend slightly longer than the length (distance) of the reciprocating horizontal movement range of the excretion cover 3, and the above-mentioned rim part a6 is integrally extended on the inner surface of the opening edge of the extended ball part a1. establish.

Further, on one side in the longitudinal direction of the ball part a1, that is, on the side where the defecation port a2 and the water supply port a3 are opened, and on the other side, there is a mounting flange a7 for mounting the toilet main body A in a suspended manner on the lower part of the back surface of the patient's bed B. , a8 are provided in the same body, and mounting flanges a7, a8 on both sides are provided.
Bolt insertion holes 4 and 4 are respectively opened in a8, and suspension brackets 6 and 7 are installed in advance through bolts and nuts 5, respectively, and the suspension brackets 6 and 7 are used to connect both sides of the toilet bowl body A to the patient's bed B. In the drawing, both ends of the suspension bracket 6 on one side are fastened and fixed to a support frame 8 that supports a guide rail c2 over its entire length, which will be described later, with bolts and nuts 9, and the suspension bracket 6 on the other side is fastened and fixed at a desired location. Both ends of the excretion bracket 7 are fastened and fixed with bolts and nuts 9 to the center frame 10 that constitutes the base frame b2 of the bed B, and the excretion cover 3 is attached from the bottom of the excretion opening 1 toward the foot part b3 of the bed B. The toilet main body A is mounted and deployed within the reciprocating horizontal movement range.

Then, the drain pipe 11 is connected to the defecation port a2 of the toilet main body A.
At the same time, connect the water supply pipe 13 from the low tank 12 for flushing the toilet built in the head part b4 of the bed B or the foot part b3 to the water supply port a3 of the toilet main body A to connect both 12 and a3. .

Next, to briefly explain the opening/closing device C of the excretion port 1 in the embodiment of the present invention, a link c1 pivoted on the lower surface of the waist mat 2, a guide rail c2 guiding the lower end of the link c1, and a reciprocating motion of the link c1. It consists of a belt body c3 and a guide hole c4 for the upper end of the link c1 that changes the link c1 into a laid down state as the belt body c3 reciprocates.

The links c1 are pivoted back and forth at a predetermined interval on both left and right sides of the lower surface of the waist mat 2, which is separated from the adjacent mat, in order to close the excretion port 1 opened in the laying mat b1 on the base frame b2.

Further, this link c1 has a connecting rod 14 installed across the lower ends of the pair of front and rear links c1 and c1 existing on the right or left side.
By protruding the fixing piece 15 that connects to the belt body c3, it is indirectly connected to the belt body c3 via the fixing piece 15.

The guide rail c2 is an elongated member with a cross-sectional shape having a guide groove 16 inside, and supports a pair of support arms 17 on the front and rear sides of the support arms 17, which are vertically installed at four locations (two at the front and two at the rear) of the base frame b2. Support arm 17
The roller 19 provided on the pivot shaft 18 with the connecting rod 14 at the lower end of the link c1 is rotatably guided and reciprocated via the belt body c3. Moving waist mats 2
to receive pressure.

The belt body c3 is wound around a driven pulley 20 provided on the support arm 17 and a drive pulley 22 provided in conjunction with a motor 21 capable of forward and reverse rotation, and is inserted and fixed into the fixed piece 15. The reciprocating movement of the belt body c3 causes the waist mat 2 to move via the link c1.

When the belt body c3 is reciprocated, that is, moved in the front-back direction via the motor 21, the guide hole c4 moves the link c1 from an upright state to a laid down state.
Alternatively, it is for guiding from a collapsed state to an upright state, and is drilled into a guide plate 23 which is fixed to the outside of the pair of left and right links c1, c1 and vertically fixed to the guide rail c2.

In addition, the guide hole c4 is located on the guide plate 2 directly below the excretion port 1.
It consists of an arcuate hole 24 formed in three parts and a horizontal hole 25 continuous from the lower end of the arcuate hole 24, and the pivot pin 26 at the upper end of the front or rear link c1 is inserted into this guide hole c4. By being slidably supported, the belt body c3 moves following the forward and reverse rotational movement of the motor 21, and the link c1 is guided to stand up or fall down.
The waist mat 2 can be changed to either a closed state of the excretion port 1 or an open state of the excretion port 1 moved below the laying mat b1.

The excretion cover 3 is composed of a cover body 3a having an opening approximately the same size as the excretion port 1 on the top and bottom, and a support frame body 3b that fits and supports the cover body 3a. and its supporting frame 3
A supporting leg 27 is vertically installed before and after the left and right frames 26, 26 of b, and a connecting rod 14 is installed across the lower ends of a pair of front and rear links c1, c1 existing on the right or left side of the supporting legs 27, and this connecting rod 14 by the pusher portion c5, and as a result, the belt body c3
A pressed piece 28 is provided which moves the cover body 3a to the excretion port 1 by the movement of the pressure piece 28. Note that this pressed piece 28
is provided with a through hole 29 through which the belt body c3 passes.

Further, the support frame 3b is supported by the guide rail c2 by slidably fitting the roller 19 provided on the pivot shaft 18 of the connecting rod 14 to the guide rail c2, similar to the waist mat 2. .

The pusher portion c5 is a pressing piece that moves the cover body 3a below the excretion port 1 that is opened as the waist mat 2 moves, and the waist mat 2 is horizontal with the arc-shaped hole portion 24 of the guide hole c4. The belt body c3 is provided at a position such that it comes into contact with the pressed piece 28 only when it reaches the boundary with the hole 25.

In addition, the upper end of the excretion cover 3 is connected to the recessed part 2 formed in the lower half of the laying mat b1 adjacent to the waist mat 2.
9 and moved below the excretion port 1,
The upper end of the cover body 3a is positioned as close to the mouth edge as possible.

The operating sequence of such switchgear C will be explained step by step.
First, the user operates the operation panel 30 provided at the head part b4 or any other desired position so that the excretor can move the waist mat 2 in one direction and lower the link c1. In the middle of this, that is, when the pivot pin 26 at the upper end of the link c1
4 and the horizontal hole part 25, the excretion cover 3 is pushed by the pusher part c5 (FIG. 7). The action continues,
The excretion cover 3 moves horizontally under the excretion opening 1 so as to connect the excretion opening 1 with one side in the longitudinal direction of the ball part a1 located directly below the excretion opening 1, and the excrement during defecation is carried out to the outside. This is to prevent the particles from scattering and ensure that they fall onto the ball part a1. After using the toilet,
When the belt body c3 is advanced in the opposite direction using the operation panel 30, the link c1 gradually changes from the collapsed state to the upright state, and the excretion port 1 is closed by the waist mat 2.
Then, the excretion cover 3 also moves in the opposite direction by the pusher part c5 and returns to its original state (third
figure). At this time, the excrement attached to the inner surface of the cover body 3a of the excretion cover 3 falls onto the floor D (without dripping), and extends over the entire length of the reciprocating horizontal movement range of the excretion cover 3. It falls onto the ball part a1 of A and is reliably received by the ball part a1.

The pusher part c5 has both a reciprocating part, and the returning pusher part c5 is constructed by fixing a pressing piece to the belt c3 immediately behind the pressed piece 28, and has a circular hole part 24 and a horizontal part. When reaching the boundary area with the hole 25, the pressed piece 28 is pushed to return the excretion cover 3 to its original position without colliding with the waist mat 2.

<Effects of the invention> As described above, the present invention moves the lumbar mat to open and close the excretion opening directly below the excretion opening in succession to the opening operation of the lumbar mat, which connects the excretion opening and the bowl of the toilet bowl, and A sick person who is provided with an excretion cover that is attached to the lower part of the bed and moved to its original position in succession with the closing action of the mat, which is linked in a series of continuous actions with the opening and closing action of the lumbar mat via an opening/closing device. In the bed, the ball part of the toilet main body extends in the opposite direction to the opening direction of the excretion port, and the opening shape of the ball part is formed into a horizontally long rectangular shape in plan, so that the waist part for opening and closing the excretion port The ball portion can be positioned under the excretion cover that spans the entire length of the reciprocating horizontal movement range of the excretion cover that operates continuously with the opening and closing operations of the mat. Therefore, the excrement that adheres to the inner surface of the excretion cover during defecation may fall (drip) onto the floor while the excretion cover is moving horizontally after defecating and while it is waiting to return to its original position. You can reliably receive everything at the ball section without any problems,
Does not stain the floor surface.

Thus, the intended purpose can be achieved.
