Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a non-flush type toilet with a lid that opens and closes and can be easily fitted into an existing Japanese-style or Japanese-Western style toilet. The tip of the opening (indicates the opening at the bottom of the toilet bowl; the same applies hereinafter) is formed to have double openings on the inside and outside, so that dirt such as feces can get stuck between the tip of the toilet opening and the toilet lid. Concerning a toilet that prevents opening/closing failure.

[Prior Art] Japanese-style non-flushing toilets are unpleasant and unhygienic, such as the waste in the toilet tank being visible through the defecation opening, flies flying in, maggots rising, and a foul odor. Improvements are being made. A toilet lid attached to the defecation opening was opened and closed by connecting it to a pedal installed on the floor of the toilet (Utility Model Publication No. 38-17681), and a similar device with a conical cap-shaped toilet lid (Utility Model Publication No. 17681, 1973).
-334878). All of these are existing stationary non-flush toilets with a toilet lid opening/closing device attached.

[Problems that the invention aims to solve] In the case of conventional toilets with opening and closing toilet lids, a toilet lid opening and closing device is attached to an existing stationary Japanese-style non-flushing toilet. It was not easy to replace or clean. Moreover, maggots that crawled up from the toilet tank or the defecation pipe during defecation could enter the toilet bowl through the defecation opening and ascend the inner wall of the toilet bowl, making it filthy and unpleasant. In addition, when defecating, feces and other filth that scatters and adheres to the inner wall of the toilet drips down and solidifies into the defecation opening, causing incomplete shielding of the defecation opening by the toilet lid, or contact between the defecation opening and the toilet lid. There were many cases where feces etc. adhered to the toilet lid and solidified, making it difficult to open and close the toilet lid smoothly.

[Means for Solving the Problems] The present invention has been made to solve the problems of conventional toilet bowls with opening/closing lids. That is, the present invention is a toilet that is used by fitting into an existing Japanese-style or Japanese-Western-style toilet, in which the toilet lid is pressed against the tip of the opening to shield the opening of the toilet during normal use, and when defecating, In toilets in which the toilet lid is opened by operating a pedal or other operating part connected to the toilet lid, a groove extending all the way around the tip of the toilet opening is bored to form an inner opening (hereinafter referred to as
This invention forms a defecation opening having a double opening: an inner opening (hereinafter abbreviated as the inner opening) and an outer opening (hereinafter referred to as the outer opening), and the inner opening is shorter than the outer opening. It is a flush sanitary toilet.

This invention is an easy-to-install or portable toilet with a lid that can be inserted into an existing Japanese-style toilet, so it can be easily installed without any special construction, and the toilet and toilet lid can be cleaned, replaced, and repaired. This can be done extremely easily, and the toilet bowl can always be kept clean. In addition, a groove that runs all the way around the tip of the defecation opening is made to create a defecation opening that consists of a double opening, an inner opening and an outer opening, and the inner opening is made shorter than the outer opening, so the opening and lid of the defecation opening are made It can prevent dirt such as feces from sticking to the contact area. Furthermore, the groove between the inner and outer openings can prevent pests such as maggots that have ascended from the lower toilet tank from entering the toilet bowl of the present invention.

[Example] Hereinafter, the present invention will be explained in more detail by way of example using FIGS. 1 to 5.

The toilet bowl body 2 has a step stool 3 almost flush with its upper edge.
are provided on the left and right. The step stool 3 is made of vinyl chloride resin, polystyrene resin, glass-reinforced epoxy resin, or the like, and is formed integrally with the main body 2 or by adhesion or other means. The defecation port 7 at the bottom opening of the main body 2 is
A groove is bored at the tip to form a double opening having an inner opening 7b and an outer opening 7a hanging slightly longer. This is to prevent filth from adhering to the outer wall of the toilet opening 7, and to prevent maggots from rising along the inner wall of the toilet bowl. An upper pedal 4a is screwed onto either the left or right side of the step stool 3, and a spring 5a is attached to the back surface of the pedal 4a to give upward restorability to the pedal 4a.
Furthermore, mounting ears 8 are provided on the left and right outer walls of the toilet main body 2 in the vicinity of the defecation opening 7 to which the mounting pieces 15 of the base 14 that support the opening/closing mechanism of the toilet lid 9 are fixed.

A weight 10 is attached to the toilet lid 9 that is in contact with the external opening 7a of the defecation port 7 of the main body 2, and is slightly unevenly distributed at the upper part of the extended rear part 9b, and a weight 10 is attached to the toilet lid 9 slightly in front of the weight 10 and protrudes from both sides. The shaft 11 is fixed to the toilet lid 9. The toilet lid front part 9a is formed in a slightly large size so as to completely cover the outer opening 7a. The upper surface of the toilet lid front portion 9a is preferably made of a smooth material and kept smooth to prevent dirt from adhering to it. The rear portion 9b of the toilet lid is normally formed to be slightly narrower than the front portion 9a of the toilet lid so as not to come into contact with the existing toilet bowl 22 when the present sanitary toilet bowl 1 is fitted into the toilet bowl 22.

The lid body 14 that supports the toilet lid 9 is formed, for example, in a substantially U-shape in plan, and the outer wall of the defecation opening 7 portion is sandwiched between the U-shaped portions, and the mounting piece 15 provided on the base body 14 and the above-mentioned main body 2 are connected to each other. Mounting ear 8 and bolt nut 16
It is fixed to the main body 2 by screwing or the like.

The toilet lid 9 is swingably supported on the base 14 with a shaft 11, and then an arm 12 is fixed to the shaft 11, and the arm 12 is further connected to the connecting rod 1 with a pin 13.
7 is connected. The connecting rod 17 extends to the top of the toilet main body 2 and is pivotally supported by a push rod 41 attached to the upper pedal 4a. Further, when the present toilet bowl 1 is used as a Japanese-style dual-purpose toilet bowl, a lower pedal 4b is attached to the outside of the toilet bowl main body 2, for example, on the front side, so that it can be operated in a standing position. That is, the connecting rod 17 includes a horizontal rod 18 connected to the lower pedal 4b by, for example, a vertical rod 19.
are concatenated. The horizontal rod 18 and the vertical rod 19 are provided with length adjustment parts 20 and 21 as desired. A spring 5b is also attached to the lower part of the lower pedal 4b, if necessary, to provide upward restorability when the pedal is depressed.
If the restoring force of the spring 5a attached to the upper pedal 4a is sufficiently strong, the spring 5b may be omitted.

When the toilet lid 9 is opened, the position of the weight 10 is adjusted such that the tip of the toilet lid 9 opens outward from the defecation opening and remains stationary, for example, by attaching the weight 10 to the upper part of the rear part 9b of the toilet lid 9 as described above. , the pivot position of the toilet lid 9, the angle of the arm 12, etc., as appropriate.

The sanitary toilet bowl 1 of the present invention can be used by being fitted into existing non-flushing dual-use toilet bowls and sinking toilet bowls of various sizes.

Reference numeral 23 indicates the floor of the toilet.

[Function] The existing toilet bowl 23 (first,
This is shown by the dashed-dotted line in Figure 3. ) and install it.
At this time, in order to block the bad odor from the toilet tank, it is desirable to fill the gap between the existing toilet bowl 22 and the main toilet bowl 1, for example, between the two toilet bowls, with a gasket made of foam material or the like.

After the main body 1 is installed, when the user steps on the step stool 2 and depresses the upper pedal 4a when using the toilet, the pedal 4a naturally descends due to the user's weight. At this time, the spring 5a disposed below the pedal 4a is pressed and contracted. At the same time, the push rod 41 connected to the pedal 4a, and further the connecting rod 17
pushes arm 12 downward via pin 13. Since the arm 12 is fixed to the shaft 11 and the shaft 11 is fixed to the toilet lid 9, the toilet lid 9 is fanned downward about the shaft 11 and opened. At this time, when the toilet lid 9 comes close to the lead, due to the action of the weight 10 attached at the rear of the toilet lid 9 and slightly unevenly distributed above, the toilet lid 9 is moved slightly from the vertical line of the toilet main body 2. It opens to the open angle and waits at that position (indicated by the dashed line in Figure 1) to prevent the adhesion of filth during defecation.

Dirt such as feces that scatters and adheres to the inner wall of the toilet main body 2 when using the toilet gradually drips down and collects near the defecation opening 7 even after the toilet is used. In the case of conventional defecation ports, feces and other filth can get around and adhere to the outer wall from the tip of the defecation port, or it can adhere and stick between the toilet lid 9 and the defecation port 7, making it difficult for the toilet lid to move smoothly. This may cause interference or malfunction. However, since the defecation port 7 of the present invention has a groove formed at its tip over the entire circumference, and is formed to have a double opening consisting of an inner port 7b and an outer port 7a that is slightly longer than the inner port 7b, Although feces and other filth may hang down and solidify directly below the inner opening 7b, it is blocked by the groove formed between the inner and outer openings, and the feces and other substances do not get around to the outer opening 7a. It will not hang down and solidify at the tip of the external opening 7a, and of course will not adhere to the external wall of the defecation opening 7. Therefore,
The smooth movement of the toilet lid 9 is not hindered by the adhesion of feces and other filth, and the feces, etc. hangs down and solidifies at the tip of the defecation opening 7, creating a gap between the defecation opening and the toilet lid 9. The shielding between the two is not hindered. Furthermore, it ascends the inner wall of the existing toilet bowl 22 and passes along the outer wall of the toilet bowl body 2 of the present invention to open the outer opening 7 of the defecation opening 7.
Even if the pests such as maggots that have reached the toilet lid 9 try to reach the inner wall of the toilet main body 2 of the present invention from the outer opening 7a through the inner opening 7b when using the toilet with the toilet lid 9 open, It is blocked by the groove formed between the openings 7b, and cannot reach the inner wall of the toilet main body 2.

Next, after defecating, when you take your foot off the upper pedal 4a,
The restoring force of the contracted spring 5a pushes up the upper pedal 4a, and the arm 12 is pulled upward via the push rod 41 and the connecting rod 17. Since the arm 12 is fixed to the toilet lid 9 via the shaft 11, the toilet lid 9 rotates upward and returns to its original position, covering the defecation opening 7 again and connecting the upper part of the toilet body 2 and the lower part of the opening. cut off.

When using the lower pedal 4b, the connecting rod 17 and the lower pedal 4b are connected via the vertical rod 19 and the horizontal rod 18, so the lower pedal 4b is operated in the same way.
The toilet lid 9 can be opened and closed in conjunction with the depression and release of the button.

[Effects of the invention] Since the toilet bowl of the present invention is a built-in type, there is no need for large-scale installation work like a stationary toilet bowl, and it is only necessary to fit it into an existing Japanese-style non-flushing toilet, making it extremely easy to use. And it can be installed at low cost. Also,
It is easy to remove, and the toilet bowl and opening/closing device are extremely easy to clean, repair, replace, etc., and can be used hygienically at all times.

Since the tip of the defecation port is formed to have a double opening, an inner opening and an outer opening, pests such as maggots are blocked by the groove between the inner opening and the outer opening, and do not reach the inner wall of the toilet bowl body of the present invention. There will be no intrusion. Furthermore, since the inner opening is shorter than the outer opening, even if feces or other filth attached to the inner wall of the toilet bowl hangs down to the tip of the inner opening and hardens, it will not reach the outer opening, making it easier to defecate. There is no need to worry about feces or the like sticking to the contact area between the outer opening of the mouth and the toilet lid and preventing the opening and closing of the toilet lid. In addition, there is no gap between the contact area between the toilet lid and the external opening due to feces, etc. hanging down and solidifying at the tip of the external opening, so the odor of the toilet tank leaks from the contact area, and pests such as flies can enter and exit. Effortlessly clean and hygienic. Furthermore, since the urinal opening is smaller in diameter than the existing toilet bowl, it is possible to prevent accidents involving children from falling.

Since a foot-operated pedal is provided as an operation part for opening and closing the toilet lid on both the step and the front side of the toilet, it can be used like a normal Japanese-style toilet or a Japanese-style dual-purpose toilet.

In this way, it is the perfect sanitary toilet for people who prefer conventional Japanese-style toilets, such as Japanese-style non-flushing dual-use toilets with aprons and sink-type toilets.
