Description

[Detailed explanation of the invention] This invention is particularly useful for temporary toilets at construction sites, general household toilets, and other toilets that use Japanese-style non-flushing toilets or simple flushing Japanese-style toilets. The present invention relates to a shielding device that is attached to a waste dropping port.

In general, the non-flush type or simple flush type Japanese-style toilets mentioned above are often half-bottomed, and are installed with a relatively large diameter filth drop opening or opening directly above the filth reservoir under the floor. . In such toilets, the top of the toilet bowl is usually covered with a lid to prevent odor leakage, etc. However, since the toilet user removes the lid to defecate, there is no possibility that there will be any leakage during the toilet. There is no shielding, so users are exposed to the bad smell that rises from inside the filth basin through the drop opening, and they can also see the inside of the filth basin below through the drop opening, and they can also see the filth in their feces from below. There was a problem with the bounce, which caused extreme discomfort and was not very aesthetically pleasing for a toilet.

This idea was created in view of the above circumstances, and its purpose is to easily install it in the waste drainage opening of a toilet such as a non-flushing type or a simple flushing type toilet by closing it. In addition to suppressing the bad odor rising from below, the filth reservoir on the bottom can be hidden from view, and even if you use the toilet with it closed inside the filth drop hole, you can ensure that the filth falls into the bottom of the filth hole. At the same time, it prevents splashing from the bottom, allowing people to use the toilet without feeling uncomfortable, and it can be easily removed from the waste droplet as needed, making cleaning etc. extremely easy. Our aim is to provide something with great practicality.

In other words, the shielding device of this invention has a flat plate shape with a diameter slightly larger than the inside diameter of the filth drop opening of a Japanese-style toilet bowl, and has a small hole in the center, and the shielding device is evenly spaced radially from the small hole. A shielding sheet with excellent heat resistance, non-adhesiveness, chemical resistance, and elasticity, such as glass fiber-filled Teflon resin, having a plurality of curved cuts extending close to the periphery is placed around this periphery in a circular shape. The apparatus main body is constructed by fixing and stretching the upper surface of the support frame disposed over the entire area, and the lower ends are connected to the peripheral support frames of the apparatus main body, and the upper end is connected to the upper opening edge of the Japanese-style toilet. A pair of left and right hangings having hooks that can be removably locked are provided, and the left and right hangings are used to suspend the main body of the device from the lower surface of the waste dropping port of the Japanese-style toilet, thereby closing the waste dropping port. With this configuration, the existing non-flush type or simple flush type Japanese-style toilet can be installed without making any changes.
The main body of the device can be easily and securely hung and installed inside the toilet's filth drop opening via a pair of hanging tools on the left and right, and only the small hole in the center of the shielding sheet of the main body of the device and the plurality of cut portions are required. The filth fall port can be closed without any gaps except for a slight opening. This prevents users who are using the toilet from looking into the toilet bowl's filth drain opening from above to see into the filth reservoir below, and it also greatly reduces the chance of the foul odor of filth rising up from below. . In addition, the dirt that falls onto the shielding sheet of the main body of the device due to urination is elastically pushed open by the plurality of tongues formed by each cut of the shielding sheet due to its own weight, and remains on the shielding sheet. It can smoothly fall to the bottom without leaving any residue on top, and as soon as the dirt falls to the bottom, each tongue of the shielding sheet instantly and automatically returns to its original closed state. This makes it possible to prevent dirt from bouncing back from below due to falling dirt. Therefore, the user can relieve himself or herself without experiencing any discomfort caused by non-flush type or simple flush type Japanese-style toilets, which has been a problem in the past. In addition, it can be easily removed and cleaned after long-term use, making it extremely easy to handle and extremely practical for toilets in rural homes and construction sites where sewage systems are not available. .

An embodiment of this invention will be described below with reference to the drawings. Here, an example of application to a general household toilet will be described. First, in FIGS. 1 to 3, reference numeral 1 in the figures is a Japanese-style non-flushing type half-bottom dual-use toilet bowl, which is fitted into a stepped floor 2. Note that, although not shown, a filth reservoir is constructed below the stepped floor 2.

Here, the toilet bowl 1 has a so-called half-bottom shape, with approximately half of the bottom portion 1a on the near side being largely opened and protruding downward in a long cylindrical shape to serve as a waste dropping port 1b. The device of this invention is provided to shield the interior of the waste dropping port 1b of the toilet bowl 1.

As shown in FIG. 4, this filth fall port shielding device includes a device body 3 having an oval shape with a diameter slightly larger than the inner diameter of the filth fall port 1b, and a device body 3 that is connected to the filth fall port of the toilet bowl 1. It is comprised of a pair of left and right hanging tools 4, 4 which are hung from above on the inner lower surface portion of 1b.

More specifically, the device main body 3 has a synthetic resin support frame 5 having an oval ring shape as shown in FIG.
and a shielding sheet 7 stretched over the upper surface of the support frame 5 with a reinforcing sheet 6 interposed therebetween.
The annular support frame 5 is formed by integrally molding a thin flange portion 5b of about 0.3 mm on the outer periphery of the upper surface of a thick band plate main body 5a having a rectangular cross-section. In addition, a plurality of small positioning dowels 5c are formed protrudingly.
Stopper insertion holes 8, 8, which will be described later, are provided at symmetrical locations.
is formed. The reinforcing sheet 6 is formed by cutting out a thin sheet made of elastic synthetic resin such as Enbi, and has an oval shape with the same size and diameter as each circumferential dimension of the flange portion 5b of the support frame 5. In addition, a plurality of curved elastic reinforcing pieces 6a are formed whose widths gradually taper from the periphery toward the center, and are fitted into the dowels 5c of the support frame 5 at the portions closer to the periphery. Matching small positioning holes 6b are formed, and holes 9, 9 that match and communicate with the stopper insertion holes 8, 8 of the support frame 5 are formed at symmetrical locations near the periphery. Furthermore, the above-mentioned shielding sheet 7 is made of a single piece of glass cloth made entirely of woven glass fibers, sufficiently impregnated with Teflon resin and baked at high temperature, which has excellent heat resistance, non-adhesiveness, chemical resistance, and elasticity. It is made by cutting out a thin sheet, and its outer periphery is the same size as the reinforcing sheet 6, and small holes 7a are formed in the center, and holes 7a are spaced radially evenly from the small holes 7a to the respective peripheral edges. A plurality of cuts 7b are formed, each curved in an arc shape or a parabolic shape in the same direction of rotation with the small hole 7a as the center, and are partitioned by the cuts 7b and each has a central small hole 7a. A tongue piece portion 7c is formed which tapers toward the end. In addition, each of the above-mentioned cuts 7b...
By forming the tongues 7c by punching them with a width of about 1.5 mm, each of the tongues 7c can be elastically deformed and moved up and down individually without getting caught and interfering with each other. The tongue portions 7c have the same number of elastic reinforcing pieces 6a of the reinforcing sheet 6, and the central elastic reinforcing pieces 6a on the lower surface of each tongue portion 7c are overlapped one by one. I'm starting to be able to do it. This shielding sheet 7 also has small positioning holes 7d... and left and right stopper insertion holes 10, 10 formed near the periphery in the same manner as described above. Then, a reinforcing sheet 6 is placed on the support frame 5, and a shielding sheet 7 is placed on top of the reinforcing sheet 6, so that each small hole 6b is overlapped.
..., 7d... are aligned by fitting them into the dowels 5c, and in this state, the flange portion 5b of the support frame 5 and the outer peripheral edges of the reinforcing sheet 6 and the shielding sheet 7 are sewn together 11 using a sewing machine or the like. The main body 3 of the device is constructed by combining the components in a polymerized state.

On the other hand, as shown in FIG. 7, the pair of left and right hanging devices 4, 4 have hanging strings 12 made of synthetic resin or the like having a diameter of about 2 to 3 mm and having flexibility and moderate elasticity, and attached to the upper and lower ends of the strings 12, respectively. They are each made of hooks 13 and 14 with holes that are connected by caulking, a stopper 15 that can hang the hook 13 at the lower end thereof, and a hook 16 that can hook the hook 14 at the upper end. The stopper 15 has an L-shaped plate shape and has a downward cut-and-raise claw part 15d on the rising piece 15a, and has a cross section formed on the support frame 5, reinforcing sheet 6, and shielding sheet 7. The rising piece 15a is inserted into the convex-shaped stopper insertion holes 8, 9, and 10 from below so as to penetrate upward, and the horizontal piece 15c is adjacent to the hole 8 on the lower surface of the support frame 5. The hook 16 at the upper end is formed by stamping and press-molding a thin plate of stainless steel or the like, and is attached by elastically riding over the small protrusions 8b on both sides of the recessed step 8a. It can be removably engaged with the left and right edges of the upper end opening from the inside to the outside, and has a holding part 16b with a cut-up claw part 16a on the lower part to which the above-mentioned latching fitting 14 can be fastened. There is.

Therefore, in the filth fall port shielding device of this invention,
A pair of left and right hanging tools 4, 4 are attached to the device main body 3, which is constructed by stretching a shielding sheet 7 in a superimposed state with a reinforcing sheet 6 interposed between the support frame 5.
In this state, for example, drop the device main body 3 vertically into the filth drop port 1b of the toilet bowl 1 of an existing toilet from above while holding the hanging devices 4, 4 in your hands,
When the device main body 3 has come out below the lower end of the filth drop port 1b, both the hanging tools 4, 4 are pulled upward to bring the device main body 3 into a horizontal state, and the peripheral edge opens at the bottom of the filth drop port 1b. The hanging tool 4 is brought into contact with the periphery from below, and in that state, the hanging tool 4,
4, and hook the upper end hooks 16, 16 on the left and right upper edges of the opening of the toilet bowl 1.

This completes the work of installing the shielding device of the present invention on the toilet bowl 1, and the entire surface of the filth drop port 1b of the toilet bowl 1 is closed at its lower end by the shielding sheet 7 of the device main body 3, and the center of the sheet 7 is closed. Only a small gap between the minute hole 7a and the narrow cut 7b remains unclosed. This seals out the bad odor from the filth storage below and almost eliminates the possibility of it coming up. Furthermore, even if the user looks down while using the toilet, the user will not be able to see the waste collection underneath due to the shielding sheet 7, and will not feel uncomfortable. In addition, the filth that falls while using the toilet hits the shielding sheet 7 of the main body 3 of the device from inside the filth falling port 1b, and the tongues 7c of the shielding sheet 7 are thin and elastic, and the lower side of the tongues 7c... Each of the elastic reinforcing pieces 6a of the reinforcing sheet 6 to be polymerized is also thin and has elasticity, so that these tongue pieces 7c, together with the elastic reinforcing pieces 6a, are elastically deformed and curved downward by the weight of the filth, thereby removing the filth. drop to the bottom. At this time, the tongue portions 7c have excellent non-adhesive properties, so that the dirt does not fall down and remain attached to it, and falls smoothly. After the dirt has fallen, each tongue piece 7c quickly and reliably returns upward due to its own elasticity and the elasticity of the lower elastic reinforcing piece 6a, and becomes a flat closed state. Prevents filth from splashing out from the sewage sump.

In addition, after using the toilet mentioned above, if you spray water from above into the dirt drop opening 1b using a device such as a shower that can supply water from the tap or a sprayer prepared separately, the entire upper surface of the shielding sheet 7 of the main body 3 of the device will be covered. It can be easily cleaned and kept in a beautiful state for a long time. Furthermore, when cleaning the toilet bowl, the hooks 16, 16 of the hanging devices 4, 4 are removed from the upper edge of the toilet bowl, and the main body 3 of the device is removed. Lower it, then turn it vertically and pull it up to open the dirt drop port 1b.
Remove the device from the inside upwards, clean the device main body 3 and the entire hangers 4, 4 in a washing area, etc., also clean the toilet bowl 1, and then reinstall the device body into the waste drop port 1b of the toilet bowl 1 as described above. By attaching the device 3 using the hanging tools 4, 4, it becomes possible to clean it even better and to continue using it in a good manner for a long period of time.

Note that this invention is not limited to the above-mentioned embodiments; for example, the materials of each part of the support frame 5, reinforcing sheet 6, shielding sheet 7, and hanging tools 4, 4 of the device main body 3 can be changed as appropriate. Also, the reinforcing sheet 6 does not need to be particularly provided.

Since this invention has been developed as described in detail above, it can be easily installed in a toilet such as a non-flushing type or an easy flushing type toilet to close it off, thereby eliminating the bad smell rising from below. At the same time, the waste collection on the lower side can be hidden from view, and even if you use the toilet with the waste collection hole closed inside the waste collection port, the waste can be reliably dropped to the bottom of the drop port, and at the same time, the waste can be dropped from the bottom. It is highly practical because splashing can be prevented, the toilet can be finished without feeling uncomfortable, and the waste can be easily removed from the inside of the waste dropping port when necessary, making cleaning etc. very easy.
