[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a portable toilet with a curtain.

[0002]

[Prior art]

 Conventionally, various types of simple toilets of this type have been provided, and a simple type has a container with a toilet seat attached with a lid, but when this lid is removed, an odor will drift. There was a drawback.

[0006] Although there is a method of sprinkling a chemical on the excrement collected in a container to prevent an odor, it has not been possible to completely eliminate the odor with this chemical.

Further, when the excrement is stored in a container, there is a disadvantage that the disposal of the excrement in the container is troublesome.

By the way, in hospitals, nursing homes and the like, there are patients who spend most of their time sleeping in their hospital rooms and even having difficulty walking. Such patients cannot move from the hospital room to the toilet, so they have no choice but to use it indoors. However, as mentioned above, there was no suitable simple toilet, which often caused the patient to feel inconvenienced.

[0006]

[Problems to be solved by the device]

 As described above, conventionally, various simple toilets have been provided, but there have been inconveniences such that the odor cannot be sufficiently prevented or the post-treatment is troublesome. Therefore, it is not always preferable to use the conventional simple toilet in a hospital room such as a hospital or a nursing home, and a simple toilet suitable for indoor use has been strongly desired.

Therefore, an object of the present invention is to obtain a simple toilet with a curtain that can prevent odors, can be easily processed afterward, and is suitable for indoor use.

[0008]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, it is formed by a tubular body protruding below the toilet bowl and a tube of a synthetic resin sheet that is pulled up in the longitudinal direction and folded into an annular shape. The excrement storage member, which is arranged so as to surround the cylindrical body by arranging the cylindrical body in the center and guides the tube from the upper side to the lower side inside the cylindrical body, and the lower side of the cylindrical body. The opening and closing means for sandwiching and welding the tube when closed and the opening and closing means arranged below the opening and closing means for opening and closing the opening and closing means. A tube transport unit having at least the tube transport unit disposed below the tube transport unit and pulled down by a pulling means of the tube transport unit; And Mel hollow base, a frame projecting from the said hollow base so as to surround the bowl, is attached to the frame, constituted by a curtain obscuring the interior of the frame.

[0009]

[Action]

 According to this invention, the opening / closing means of the tube transport unit sandwiches and welds the tube of the excrement storage member to close the tube. In this state, when the excrement is dropped from the toilet bowl, the excrement falls to the closed portion of the tube passing through the inside of the cylinder below the toilet bowl and stays there. Subsequently, when the opening / closing means is opened, the pulling-down means pulls down the tube. After this, when the tube is closed again by the opening / closing means, the tube will be closed at two locations. That is, the tube is occluded at the lower part and the upper part of the excrement. Therefore, excrement is sealed and stored in the tube.

Further, the curtain is attached to a frame surrounding the toilet bowl and covers the inside of the frame. Therefore, the person doing the work inside is not seen by others.

【Example】

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

FIG. 1 schematically shows an embodiment of a simple toilet with a curtain according to the present invention. In the figure, a simple toilet 2 is placed on a hollow base 1. Further, four pillar frames 3 and a handrail frame 4 are projectingly provided on the hollow base 1, and the handrail frame 4 is connected to substantially the center of each pillar frame 3. Further, a frame frame 5 is connected to the upper end of each support frame 3. On this frame 5, three opaque curtains 6, 7, 8 hang down. The single curtain 6 is directly attached to the frame 5, and covers the left and right sides and the rear side of the simple toilet 2. The other two curtains 7 and 8 are movably supported by being hung from a curtain rail attached to the frame 5, and cover or open the front of the simple toilet 2.

Further, since the hollow base 1 has a sufficient height, the step 9 is formed on the front side thereof, which facilitates the ascent. Further, four casters 11 are attached to the bottom of the hollow base 1 so that the toilet can be moved.

Since the front, rear, left and right sides of the simple toilet 2 are covered with the curtains 6, 7, 8 in this manner, a person who uses this toilet does not have to be seen by other people. Further, since each of the support frame 3, the handrail frame 4 and the frame 5 is a pipe frame, and the wall of the toilet is formed by these pipe frames and three curtains, the weight of the toilet is reduced. ing. The weight of the toilet and the casters 11 under the empty space 1 allow the toilet to be easily moved. Therefore, for example, it is easy to move within a patient room or move from a patient room to another patient room, and can be shared by a plurality of people. Also, if this toilet is installed in a mobile facility that is a remodeled car, it can be used inside the car.

The toilet can be easily assembled and disassembled. That is, each carten 6, 7, 8 can be attached to or removed from the frame 5, and each frame 3, 4, 5 can be attached to or removed from the hollow base 1. Therefore, this toilet can be easily disassembled, transported, and installed in an arbitrary place.

2 and 3 show the structure of the simple toilet 2, FIG. 2 is a perspective view showing the simple toilet 2, and FIG. It is a sectional view.

As shown in these figures, in this simple toilet 2, a housing 12 forming the outer wall of the toilet 2 is fixedly arranged in the hollow base 1, and inside the housing 12, A shelf 13 is provided. A hole is formed at approximately the center of the shelf 13, and the open end of the bosh-shaped cylinder 14 is connected to the peripheral edge of the hole, and the cylinder 14 is projectingly provided there. Further, inside the housing 12, the tube transfer unit 15 is arranged on the hollow base 1, and the transfer section 16 of the tube transfer unit 15 is located below the hole of the shelf 13. Further, a hole is provided in the hollow base 1 at a position below the transport unit 16. The drive unit 17 of the tube transport unit 15 is arranged in parallel with the transport unit 16, and its operation panel is attached to the side wall of the housing 12.

On the other hand, a western-style toilet seat 18 is fixed to the upper open end of the tubular body 14, and the western-style toilet seat 18 is surrounded by a toilet seat frame 19. A lid 20 is attached to the toilet seat frame 19, and by opening and closing the lid 20, the Western style toilet seat 18 can be opened and the Western style seat 18 can be covered. Further, the toilet seat frame 19 is removable from the housing 12, and when the toilet seat frame 19 is removed from the housing 12, the excrement storage member 22 can be stored on the upper side of the shelf 13.

The excrement storage member 22 is obtained by pulling a tube 23 of a relatively thin synthetic resin sheet in the longitudinal direction and folding it into an annular shape. The excrement storage member 22 is arranged on the shelf 13 so as to surround the cylindrical body 14. The tube 23 of the excrement collection member 22 is led out from the gap between the toilet seat frame 19 and the Western-style toilet seat 18, slides on the upper side surface of the Western-style toilet seat 18, passes through the inside of the tubular body 14, and then the tube. It reaches the inside of the hollow stand 1 via the carrying section 16 of the carrying unit 15.

The transport unit 16 of the tube transport unit 15 sandwiches and closes the tube 23, and pulls down the tube 23 when the tube 23 is not sandwiched. Every time the tube 23 is pulled down by the carrying section 16, the tube 23 is accumulated in the hollow stand 1. A tube storage box 24 for storing the tubes 23 is arranged in the hollow base 1.

A door 25 is attached to the rear side of the hollow base 1 as shown in FIG. 4, and by opening the door 25, the tube reservoir box 24 is taken out and the tubes in the tube reservoir box 24 are removed. 23 can be discarded.

In addition, on the hollow base 1, there are provided a hole 26 located below the transfer section 16 of the tube transfer unit 15, a hole 27 for projecting each support frame 3, and a handrail frame 4. A hole 28 for projecting is formed.

The transfer section 16 of the tube transfer unit 15 is configured as shown in FIGS. 5, 6 and 7. 5 is a perspective view, FIG. 6 is a plan view when viewed from above, and FIG. 7 is a side view.

As is apparent from these figures, the transport section 16 has a support frame 31, and this support frame 31 rotatably supports two shafts 32, 33. The one shaft 32 pivotally supports a pair of gears 35a and 35b and a pair of cams 36a and 36b outside the support frame 31, and pivotally supports a pair of rollers 37a and 37b inside the support frame 31. . The other shaft 33 pivotally supports a pair of gears 38a and 38b and a pair of cams 39a and 39b outside the support frame 31, and pivotally supports a pair of rollers 40a and 40b inside the support frame 31. There is. Here, since the gears of the one shaft 32 mesh with the gears of the other shaft 33, when the one shaft 32 is rotated, the other shaft 33 rotates in the opposite direction.

The support frame 31 supports a pair of U-shaped holding frames 41a and 41b, and flat plates 42a and 42b are attached to the upper sides of the holding frames 41a and 41b. . A pair of seat heaters 43a and 43b are fixed to the edges of the flat plates 42a and 42b.

The one end of the holding frame 41a is rotatably attached directly to the support frame 31 as shown in FIG. Further, the other holding frame 41 b is connected to the support frame 31 via the swing column 44. That is, the lower end of the swing column 44 is rotatably directly attached to the support frame 31, and the upper side of the holding frame 41b is rotatably attached to the swing column 44. Further, the lower end of the holding frame 41b is rotatably attached to the link rod 45.

The one holding frame 41a and the swing column 44 are urged by the coil springs 46 and 47 in the mutually opening direction, and are always in contact with the cam 36a and the cam 39a.

Further, the link rod 45 has one end connected to the support frame 31 via a spring 48, and is constantly pulled by the spring 48. The other end of the link rod 45 is rotatably attached to the undulating arm 49. The undulating arm 49 is pivotally supported by a pedal support rod 51, and the pedal support rod 51 penetrates the support frame 31 and is rotatably attached. Further, the pedal support rod 51 is bent in an L shape, and is bent again at its tip to form a hook-shaped tip 51a. The hook-shaped tip 51a is fitted in the groove 52 formed in the gear 35a.

Further, the pedal support rod 51 penetrates the drive unit 17, is led out to the outside of the housing 12, and the pedal 53 is attached to the end led out to the outside. When the pedal 53 is depressed, the pedal support rod 51 is rotated, the hook-shaped tip 51a of the pedal support rod 51 moves along the groove 52 of the gear 35a, and the hook-shaped tip 51a is disengaged from the groove 52.

Here, as shown in FIG. 7, when the cam 36 a and the holding frame 41 a are raised by the cam 39 a and the swinging column 44 is raised, the holding frame 41 b connected to this swinging column 44 is also Since it is raised, the pair of holding frames 41a and 41b face each other. At this time, the hook-shaped tip 51a of the pedal support rod 51 is fitted in the groove 52 of the gear 35a, and the spring 48 urges the undulating arm 49 via the link rod 45 in the direction to lie down. As a result, the hook-shaped tip 51a of the pedal support rod 51 reaches the end point of the groove 52 of the gear 35a, and the undulating arm 49 falls. Along with this, the lower end of the holding frame 41b connected to the link rod 45 is pulled leftward, whereby the holding frame 41b is urged rightward at the upper end with the connecting position with the swing column 44 as a fulcrum. To be done. As a result, not only the pair of holding frames 41a and 41b face each other, but also the edges of the flat plates 42a and 42b above them, that is, the seat heaters 43a and 43b are pressed against each other.

A mechanism including a swing column 44, a link rod 45, coil springs 46 and 47, a spring 48, and an undulating arm 49 is provided on each gear 35b and 38b side as well as each gear 35a and 38a side. It is provided.

As shown in FIG. 2, the panel surface of the drive unit 17 forms a part of the side wall of the housing 1. Not only the pedal 53 is arranged on the panel surface, but also a main switch 54, a pilot lamp 55, and a dial type counter 56 are arranged.

FIG. 9 shows an internal configuration of the drive unit 17. In the figure, the carrying motor 61 is connected to the shaft 32 of the carrying unit 16 and rotates the shaft 32 in the direction of arrow A (shown in FIG. 7).

The pedal limit switch 62 is a normally open contact, and when the pedal 53 is depressed and the pedal support rod 51 rotates sufficiently, a cam (not shown) provided on the pedal support rod 51 causes the pedal limit switch 62 to rotate. Turned on.

The dial-type counter 56 is preliminarily operated before the use of the toilet, and is rotated clockwise by an appropriate angle. After that, the dial type counter 56 is rotated counterclockwise little by little each time the toilet is used as described later, and when it returns to the original position, it notifies the control unit 63 of this fact.

When the pulse generator 64 is activated, it generates a pulsed electric current and causes this electric current to flow through the seat heaters 43a and 43b to heat the seat heaters 43a and 43b.

The main switch 54 is for turning on and off the power supply of the drive unit 17.

The control unit 63 centrally controls the drive unit 17, drives the transport motor 61, activates the pulse generation unit 64, and turns off the main switch 54 that is turned on. To do.

In the state shown in FIG. 7 described above, the tube 23 of the excrement storage member 22 is led out from the gap between the toilet seat frame 21 and the Western-style toilet seat 18, and slides on the upper surface of the Western-style toilet seat 18. Is guided to the inside of the tubular body 14 and further reaches the tube storage box 23 via the transport section 16. In the transport unit 16, the tube 23 is sandwiched between the flat plates 42a and 42b and closed, and both edges of the tube 23 made flat by this are sandwiched between the rollers 37a and 40a and between the rollers 37b and 40b. There is.

In this state, the control unit 63 has already started the pulse generation unit 64 only once. When activated, the pulse generator 64 causes a pulsed current to flow through each of the sheet heaters 43a and 43b, causing the seat heaters 43a and 43b to generate heat. As a result, the tube 23 is welded and closed at the position sandwiched between the flat plates 42a and 42b.

Here, when the excrement is dropped from the western-style toilet seat 18, the excrement reaches the closed part of the tube 23, that is, the part sandwiched between the flat plates 42a and 42b, and these flat plates are placed. Stay on 42a, 42b.

After that, when the pedal 53 of the pedal support rod 51 is depressed, the pedal support rod 51 is rotated and the pedal limit switch 62 is turned on. The control unit 63 detects that the switch 62 is turned on and rotates the transport motor 61. As a result, the shaft 32 of the transport unit 16 is rotated in the direction of arrow A (shown in FIG. 7), and the other shaft 33 is rotated in the opposite direction.

At this time, since the pedal support rod 51 is rotating, the hook-shaped tip 51a of the pedal support rod 51 rises as shown in FIG. 10 and is disengaged from the groove 52 of the gear 35a. When the hook-shaped tip 51a is disengaged from the groove 52 of the gear 35a, the gear 35a rotates, so that the hook-shaped tip 51a slides on the smooth peripheral edge of the gear 35a.

As the shafts 32 and 33 rotate, the cam 36a and the cam 39a also rotate in their respective directions, and the shorter diameter side of these cams contacts the one holding frame 41a and the swing column 44. At this time, the one holding frame 41a and the swing column 44 are opened mutually by the elastic force of the coil springs 46 and 47. Further, the other holding frame 41b is biased to the left on the upper side with the connection position with the link rod 45 as a fulcrum, and falls down together with the swing column 44. As a result, the pair of holding frames 41a and 41b are in a state of being opened to each other.

The state in which the holding frames 41a and 41b are opened from each other is maintained while the shafts 32 and 33 rotate once.

On the other hand, as described above, both edges of the tube 23 are sandwiched between the rollers 37a and 40a and between the rollers 37b and 40b. Therefore, when the holding frames 41a and 41b are opened, the tube 23 is pulled downward as the rollers 37a and 40a and the rollers 37b and 40b rotate, and excrement is collected. The occluded site is also lowered.

As the gears 35a and 38a further rotate, the long diameter side of each of the cams 36a and 39a contacts the one holding frame 41a and the swing column 44, so that the pair of holding frames 41a and 41b are re-engaged. Close.

Here, since the undulating arm 49 is constantly urged in the direction in which the undulating arm 49 is laid down by the tension of the spring 48, the gears 35a and 38a rotate once, and the hook-shaped tip 51a of the pedal support rod 51 is rotated by the gear. When reaching the groove 52 of 35a, the hook-shaped tip 51a is fitted into the groove 52, and thereby returns to the state shown in FIG. 7 again.

At this time, since the pedal support rod 51 rotates in the opposite direction to that when the pedal 53 of the pedal support rod 51 is depressed, the pedal limit switch 62 is turned off. The control unit 63 detects that the switch 62 is turned off and stops the transport motor 61.

When each of the gears 35 a and 38 a makes one rotation in this way and the pedal limit switch 62 is switched from on to off, the control unit 63 activates the pulse generation unit 64. When activated, the pulse generator 64 causes the seat heaters 43a and 43b to generate heat, thereby welding and closing the tube 23.

Therefore, the tube 23 is closed at the lower part where the excrement is retained, is pulled down by the transport unit 16, and then is closed again. That is, the tube 23 is closed at the lower part where the excrement is retained and the upper part thereof to seal the excrement.

If the excrement is sealed in the tube 23 in this manner, the odor of the excrement does not drift and the excrement does not leak out. The tube 23 in which the excrement is sealed is stored in the tube storage box 24.

On the other hand, as described above, the dial counter 56 is previously rotated clockwise by an appropriate angle, and the control unit 63 activates the pulse generator 64 when the dial counter 56 is activated. Rotate counterclockwise by a predetermined minute angle.

Here, the series of operations from the depression of the pedal 53 to the pulling down and closing of the tube 23 described above are repeated every time the toilet is used, and each time the controller 63 is operated. Rotates the dial counter 56 counterclockwise by a predetermined minute angle. Therefore, each time the tube 23 is pulled down, the dial type counter 56 is repeatedly rotated counterclockwise by a small angle and finally returns to its original position. When the dial type counter 56 is repeatedly rotated counterclockwise and returns to the original position, the dial type counter 56 notifies the control unit 63 of this fact. The control unit 63 turns off the main switch 54 when the dial type counter 56 returns to the original position. When the main switch 54 is turned off, even if the pedal 53 is depressed and the pedal limit switch 62 is turned on, the carrying motor 61 does not operate. This stops pulling down the tube 23.

Further, since the tube 23 of the excrement storage member 22 is pulled down by the rotation of the rollers 37a, 40a and the rollers 37b, 40b, the length that can be lowered at one time is the length of these rollers. Equivalent to the length of the circumference. Therefore, if the total length of the tube 23 is known, the number of times the tube 23 can be pulled down, that is, the number of times the series of operations from the depression of the pedal 53 to the pulling down and closing of the tube 23 can be repeated is clear. Become.

Therefore, when the excrement storage member 22 is initially deployed, the number of times that the tube 23 can be pulled down is determined according to the length of the tube 23, and the dial counter 56 is set to the time by the rotation angle corresponding to the number of times. If the tube 23 is rotated in advance, the dial counter 56 is rotated counterclockwise little by little each time the tube 23 is pulled down, and when the tube 23 is almost used up, the dial counter 56 returns to its original position. Returning to the position, the lowering of the tube 23 is stopped.

When the tube 23 is almost used up as described above, if the main switch 54 is turned off and the pulling down of the tube 23 is stopped, the toilet cannot be used from that time onward. It becomes clear when to replace. At this time, the tube reservoir box 24 may be pulled out from the hollow stand 1 and the used tube 23 may be removed from the tube reservoir box 24.

As described above, in the toilet of the above-mentioned embodiment, the tube 23 is welded and closed at various places, so that the excrement in the tube 23 can be sealed. Therefore, the odor of excrement does not drift and the excrement does not leak out. Furthermore, the subsequent processing can be simply completed because the used tube 23 accumulated in the tube reservoir box 24 is simply discarded.

In addition, since the tube 23 is pulled down each time the toilet is used, the tube 23 slides on the upper side surface of the western-style toilet seat 18 each time the tube 23 on the upper side surface is newly added. To be done. Therefore, the upper side of the Western-style toilet seat 18 on which a person sits can be always kept clean.

The step 9 shown in FIG. 1 is formed on the hollow base 1 in the above-described embodiment. Instead of step 9, as shown in FIG. 11, a step frame 71 and a frame 71 are used. And each step 72 supported by.

Further, in the above embodiment, the Western-style simple toilet 2 is shown, but a Japanese-style simple toilet may be placed on the hollow stand 1. 12 and 13 show an example of a Japanese-style simplified toilet, FIG. 12 is a perspective view of this Japanese-style simplified toilet, and FIG. 13 is a cross section of this Japanese-style simplified toilet. It is a figure.

As shown in these figures, this simple toilet 81 is placed on the hollow base 1, and a Japanese-style toilet 83 is arranged on the housing 82 of this toilet. Two treads 84 are fixedly arranged on both sides of the Japanese style toilet 83. A shelf 85 is disposed inside the housing 82, and a bosh-shaped cylindrical body 87 is projectingly provided on the shelf 85. There is a slight gap between the upper open end of the tubular body 87 and the Japanese style toilet 83.

An annular excrement storage member 88 is arranged on the shelf 85 so as to surround the tubular body 87. The excrement storage member 88 is formed by pulling a relatively thin synthetic resin sheet tube in the longitudinal direction and folding it into an annular shape. The tube 89 of the excrement storage member 88 is led out through the gap between the Japanese style toilet 83 and the tubular body 87, and is guided downward through the inside of the tubular body 87.

Further, inside the housing 82, the tube transport unit 91 is arranged on the hollow stand 1. The tube transfer unit 91 has the same structure as the tube transfer unit 15 in the Western-style simple toilet 2, and includes a transfer section 92 and a drive section 93.

Here, every time the Japanese-style simple toilet is used, the pedal 94 of the drive unit 93 is depressed, and the transport unit 92 pulls down the tube 89 to close it. As a result, the tube 89 is stored inside the hollow stand 1.
