Description

[Detailed description of the invention] This invention relates to an improvement of a bed device with a toilet bowl.

For example, ``There are a large number of people, such as the sick and elderly, who are unable to wash themselves while lying on the floor,'' and ``bed devices with toilet bowls have been developed for such people.''
Conventionally, as such a bed device with a toilet bowl, there was a
There is one as shown in No. 6-181888.

That is, a sealing part is formed in the cushion body layered on the top surface of the bed frame, a lid body is provided in this opening part so that it can be opened and closed freely, and a toilet that slides horizontally along a rail on the bottom surface side of the bed frame is provided. The rotation of the lid body and the slide of the toilet bowl are linked by a link, and when the lid body is rotated downward and the opening □ is opened during use, the toilet bowl is positioned below the opening □. However, according to such conventional devices, the toilet bowl is configured to slide horizontally on the lower surface side of the bed frame, so the toilet bowl cannot be inserted into the opening □. Not only is there a level difference between the top open surface of the toilet and the top surface of the cushion body, but also a gap is created between the top closed surface of the toilet and the bottom surface of the bed frame, so that filth is deposited on the inner peripheral surface of the opening. This invention was made based on the above-mentioned circumstances, and its purpose is to protect the toilet bowl from the cushion body when in use. To provide a bed device with a toilet bowl that can be inserted into the opening of a toilet bowl and prevent filth from adhering to the inner circumferential surface of the entrance part or scattering around it.

An embodiment of the present invention will be described below with reference to the drawings.

1 in the figure is a bed frame. A net 2 is stretched over the surface of this bed frame, and a cushion body 3 is placed on this net 2.A cushion body 3 is placed approximately in the center of the cushion body 3 along the longitudinal direction of the bed frame. A long rectangular entrance portion 4 is formed.This closing portion 4
The inner circumferential surface of the cushion body 3 is inclined outwardly from the upper surface side to the lower surface side, and a frame body 5 is iron-inserted into this inner circumferential surface from the lower surface side. The bed frame is provided with a support frame 6 that surrounds the closing portion 4, and supports 7, 7 are fixed to the upper ends of the support frame 6 at positions corresponding to the widthwise center of the entrance portion 4. It's being talked about.

A drive shaft 8 is horizontally supported between the lower ends of the supports 7, 7. A first sprocket 9 is lacquered to one end of the drive shaft 8. At the upper end of one of the supports 7 on the side of the first sprocket 9, there is a motor 0 and a reducer 11.
A driving device 12 is provided which is integrated with the following. A second sprocket 14 is attached to the output shaft 13 of this drive device 12.
A chain 15 is stretched between the second sprocket 14 and the first sprocket 9. Therefore, the drive shaft 8 is adapted to be rotated by the drive device 12. A first actuator 16 and a second actuator 17 are provided at both ends of the drive shaft 8, with their ends connected at an angle of approximately 90 degrees in the circumferential direction of the drive shaft 8. A roller 8a is rotatably provided at the other end of each of the operating punches 16, 17. Further, mounting members 18 are provided on the support frame 6 symmetrically along the width direction of the bed frame around the supports 7, 7.
...is provided. One mounting member 18 in the width direction,
18, first parallel links 20, 20 each consisting of a pair of straight punches 19a, 19b are connected to each of the straight punches 19a, 19.
one end of b is pivotally connected, and the other mounting member 18
, 181 are provided with second parallel links 22, 22, which similarly consist of a pair of straight punches 21a, 21b, and are arranged at the negative end of each straight punch 21a, 21b. One of the straight punches 19a, 21a of the first and second parallel links 20, 22 has a substantially U-shaped cross section, and an O-ring 18 provided at the other end of the operating shafts 16, 17... is engaged. Moreover, each straight punch 19a, 19 of the first and second parallel links 20, 22
The other ends of b, 21a, and 21b are respectively connected by a first connecting plate 23 and a second connecting plate 24 which are pivotally connected to the pins. Therefore, as the working villages 16 and 17 rotate, the first and second parallel links 20 and 22 swing about the mounting members 8 through the rollers 18. In the first connecting plate 23, a cushion body 25 is provided on a base plate 24a, and closing bodies 26 formed to have approximately the same size as the closing part 4 are attached to both longitudinal ends of the base plate 24a. They are connected and fixed via angle portions 27, 27.

Further, each of the second connecting plates 24 has a pair of engagement pins 2.
8 and 28 are stepped, and a toilet bowl 29 is detachably attached to these engaging pins 28 and 28. That is, toilet bowl 2
9 is formed in the shape of a rectangular box with an open top surface and approximately the same size as the above-mentioned entrance portion 4, and a cover plate 30 made of an elastic material such as rubber is attached to the edge of the opening. Attachment pieces 32, 32 each having a pair of notches 31, 31 are fixed to both longitudinal ends of the toilet bowl 29, and the toilet bowl 29 is installed by engaging the notches 31, 31 with the engaging pins 28, 28. It is detachably connected to the second connecting plate 24. Further, at the upper part of one longitudinal end of the toilet bowl 29, as shown in FIGS. 8 and 9, there is a support 34 having both ends bent into an L shape and a U-shaped bent part 33 in the center. It is installed rotatably along the width direction of the toilet bowl 29.

Tightly wound coils 35, 35 as movable members are attached to both ends of the branch 34 protruding from the side surface of the toilet bowl 29, and a shield is attached to the bent portion 33 located at the widthwise center of the toilet bowl 29. 36 is installed. The above densely wound coil 3
5 and 35 support the twill piece 37a provided near the closing portion 4 when the toilet bowl 29 is raised as shown in FIG. 9 as the second parallel link 20 rotates. As the supporting member 34 is spread out by this assistance, the shielding body 36, which had been lying horizontally within the toilet bowl 29, stands up and projects from the opening 4 to the upper surface side of the cushion body 3. Further, when the toilet bowl 29 is lowered and the support between the twill piece 37 and the closely wound coils 35, 35 is removed, the shield 36 rotates in the direction of falling down due to its own weight. Furthermore, the support frame 6
, support plates 37, 37 are vertically provided near the mounting members 8, 8 that support the second parallel links 22, 22.

A support shaft 38 is installed between the lower ends of these support plates 37, 37. This support shaft 38 has an L-shaped cross section, is formed to have approximately the same length as the toilet bowl 29, and has an inverted U-shaped engaging portion 39 on the upper surface of one side thereof. The toilet cover 4 is supported in a swingable and removable manner by engaging the parts 39.The toilet cover 4 is normally balanced with one side tilted upward, and the second parallel link 22 When the toilet bowl 29 descends due to the rotation and enters the bottom side of the toilet bowl cover 40, it is pushed by the toilet bowl 29 and rotates to close the top surface of the toilet bowl 29.Next, The operation of the above configuration will be explained.

First, normally, as shown in FIG. 2, the first working village 16 is rotated to a substantially vertical position, thereby holding the first parallel link 20 substantially horizontally. therefore,
The shielding body 26 attached to the end of the first parallel link 20 via the first connecting plate 23 is connected to the opening 4 of the cushion body 3.
is blocked. In order to use the toilet bowl 29 from this state, the agitator 12 is activated and the drive shaft 8 is rotated clockwise as indicated by arrow a in FIG. When the drive shaft 8 rotates clockwise, the first and second working villages 16 and 17 are interlocked. FIG. 3 shows the drive shaft 8 rotated approximately 45 degrees; The first working punch 16, which was previously vertical, and the second working punch 17, which was previously horizontal, both form an angle of about 45 degrees.Therefore, the first parallel link 20 rotates downward, Since the second parallel link 22 rotates upward, the shield 26 comes out of the entrance 4 and the toilet bowl 29 rises.Then, the drive shaft 8 further rotates approximately 45 degrees clockwise, and the second parallel link 22 rotates upward. When the first working village 16 is horizontal and the second working village 17 is vertical, the second parallel link 22 is moved from the second working punch 17 to the bottom side of the bed frame as shown in FIG. Since the toilet bowl 29 is attached to the end of the second parallel link 22 via the second connecting plate 24, it protrudes into the opening 4 of the cushion body 3. Also, at this time, the shield 36 stands up and protrudes from the closing portion 4 as shown by the chain line in FIG.
If the drive unit 1 is used with the drive unit protruding into the open part 4,
2 to rotate the drive shaft 8 in the opposite direction.

Then, the first working village 16 and the second working village 17 rotate as shown in FIG. 2 through the state shown in FIG. 3. In other words, the first working village 16 becomes almost vertical; The second working punch 17 becomes almost horizontal.The first working punch 16 becomes vertical, so that the first parallel link 20 rotates upward and almost engages with the bottom side of the bed frame. Since it becomes horizontal, the shielding body 26 attached to this end enters into the entrance part 4. Also, since the second working village 17 becomes almost horizontal, the second parallel link 22 rotates downward. As a result, the toilet bowl 29 slips out of the opening □ 4 and is displaced downward.Then, the toilet bowl 29 enters the bottom side of the toilet bowl cover 4Q, so that the top surface opening □ is opened by this toilet cover 401 as shown in FIG. Therefore, the toilet bowl 29
This prevents the smell of filth stored inside the tank from wafting around. That is, according to the bed device with toilet bowl of Yokinari, the toilet bowl 2
When the toilet bowl 9 is used, the toilet bowl 29 can be made to protrude into the closed part 4, so that the level difference between the open top surface of the toilet bowl 29 and the top surface of the cushion body 3 becomes small.

Therefore, it is difficult for dirt to adhere to the inner circumferential surface of the opening 4, so that it can be used hygienically. Further, since the toilet bowl 29 is detachably attached to the second parallel link 22 via the second connecting plate 32, the toilet bowl 29 is attached to the second parallel link 22 via the second connecting plate 32.
It can be removed and cleaned easily. In the present invention, the means for driving the drive shaft may include a handle provided on the drive shaft instead of the drive device, and the drive shaft may be manually rotated by the handle.

As described above, this invention is based on the above-mentioned toilet by alternately rocking the toilet bowl and the closing body.
Since the toilet can be inserted into the interior, the toilet can be used with a smaller level difference between the upper surface of the toilet bowl and the upper surface of the cushion body.

Therefore, it prevents dirt from adhering to the inner circumferential surface of the toilet, making it possible to use the toilet hygienically over a long period of time, as well as allowing waste to be easily and reliably drained into the toilet bowl. It has the following advantages.
