Description

[Technical field]

[0001] The present invention relates to improving the convenience of preventing wastewater from leaking from the gap between the toilet body and the toilet seat when using a seated toilet. [Background technology]

[0002] Generally, a seated toilet consists of a toilet body and a toilet seat, and there is a gap between the toilet body and the toilet seat due to the legs attached to the underside of the toilet seat. This gap can allow urine to leak when a person urinates while sitting, or cleaning water for the body part cleansing function to leak. Hereinafter, urine and water used for washing human private parts leaking from the gaps in a seated toilet will be referred to simply as wastewater.

[0003] As a method for solving the above-mentioned problem of sewage leakage, Patent Document 1 describes a method for attaching a belt-shaped sewage receiving part to the toilet bowl, forming a gap between the part and the toilet bowl, so that sewage that exceeds the upper end of the sewage receiving part can flow down through the gap, preventing leakage along the toilet bowl and preventing accumulation of sewage in the sewage leakage prevention device itself. Furthermore, by using a linear metal member as part of the attachment part, it can be adapted to various shapes of toilet bowls and sizes of gaps. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2011-234767 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in Patent Document 1, in order to achieve the effect of preventing sewage leakage, the position and height of the sewage receiving part must be appropriately installed, and there was a problem that it was difficult to balance the high degree of freedom to accommodate the variety of seated toilets with maintaining an appropriate state in actual use. For example, when a linear metal member is used for the mounting part, the degree of freedom of adjustment is high, but the gap between the toilet bowl and the toilet seat is also a part that is difficult to see with the naked eye, and it may be difficult for users to adjust and install it to fit the various seated toilets. In addition, even if it is properly installed, there have been complaints that the mounting part may shift or the height of the sewage receiving part may change as the seated toilet is used, causing sewage leakage. Furthermore, when the sewage leakage prevention device is removed for cleaning the inside of the toilet, the adjusted shape may be lost, and readjustment may be required, which was also unpopular.

[0006] Regarding the wastewater collection section, there has been a demand for a product that extends to the rear of the toilet, not just the front of the bowl; however, if the rear of the toilet is included, the variety of shapes will increase, making it more difficult to respond to requests. In addition, manufacturing a large product separately would be too costly, and even for sales, the storage space and shipping costs would increase, making the product priced so that it cannot be purchased casually. Furthermore, depending on the usage situation, it may be desirable to set the sewage collection area to be somewhat more noticeable so as to effectively prevent leakage only when used by people who require care and who tend to leak frequently, while in other cases it may be desirable to prioritize easier cleaning and have the sewage collection area be less noticeable. Another issue was that it was not possible to meet the different needs of different people and situations when using the same sit-down toilet.

[0007] Unfortunately, most of the products available on the market to prevent sewage leakage are limited to use while sitting due to issues with the installation location and appearance, and tend to be used only in environments where the parties involved can accept, such as at home. In fact, very few public toilets have been designed to prevent sewage leakage, making them prone to leaks. This not only prevents users from using the toilet comfortably, but also increases the burden on cleaning staff, and the situation in which people are forced to spend time cleaning toilets while putting pressure on their original work amid a labor shortage is considered a great loss for society. In addition, although the number of people using the toilet while sitting has been increasing in recent years, there are still opportunities to use the toilet with the seat raised. For example, it is necessary to consider that there are uses other than urination while standing, such as flushing feces from diapers or use when vomiting. It is desirable to have a sewage leakage prevention device that does not impair convenience in public places and is psychologically acceptable.

[0008] The present invention aims to provide a sewage leakage prevention device that prevents sewage from leaking from the gap between the toilet body and the toilet seat when a seated toilet is used, which is compatible with a variety of seated toilets, can be easily adjusted to the desired level of leakage prevention, can maintain an appropriate installation state, and improves convenience even in public toilets. [Means for solving the problem]

[0009] In order to solve the above problems, the following sewage leakage prevention device was invented. The sewage leakage prevention device of claim 1 is a sewage leakage prevention device that prevents leakage of sewage from a gap between a toilet body and a toilet seat of a seated toilet, the sewage leakage prevention device having a substantially band-shaped sewage receiving part for receiving sewage, an attachment part for removably attaching the sewage receiving part to the toilet body, and a retention part for retaining the attachment position of the attachment part, the sewage receiving part having at least one or more gap retention parts that can form a gap for draining sewage between the sewage receiving part and an inner peripheral edge of the toilet, and the upper end of the sewage receiving part is arranged so as to be flat. the lower end of the sewage receiving portion can be located inside the inner periphery of the toilet body in a plan view and can be located below the height of the upper end of the toilet body in a side view, the sewage receiving portion can be located inside the inner periphery of the toilet body in a plan view and can be located below the height of the upper end of the toilet body in a side view, and the sewage received in the sewage receiving portion can be caused to flow down to the inner surface of the sewage receiving portion, and the sewage that exceeds the sewage receiving portion can be caused to flow down to the gap portion for draining sewage, A sewage leakage prevention device characterized in that part or all of the mounting part is placed on the upper surface of the toilet bowl, the position of the mounting part is changeable on the upper surface of the toilet bowl, the approximately horizontal position of the sewage receiving part is changeable, and the holding part holds the position of the mounting part or can hold the mounting part at a position within a certain range on the upper surface of the toilet bowl.

[0010] In the sewage leakage prevention device of claim 2, the attachment part has an arm part connected to the sewage receiving part and an adjustment part provided on part or all of the arm part, the adjustment part is made of a flexible or elastic material, and is capable of pressing the upper end of the sewage receiving part or the upper ends of the arm part and the adjustment part against the bottom surface of the lowered toilet seat, and is capable of pressing the lower surfaces of the arm part and the adjustment part against the top surface of the toilet bowl, and the height position of the sewage receiving part can be changed depending on the distance between the bottom surface of the lowered toilet seat and the top surface of the toilet bowl.

[0011] In the sewage leakage prevention device of claim 3, a connecting portion is provided that enables multiple sewage receiving portions to be connected, making it possible to adjust the length of the connected sewage receiving portions, and the connecting portion makes it possible to adjust the opening angle of the sewage receiving portions on both sides of the connecting portion according to the shape of the inner edge of the toilet body. Effect of the Invention

[0012] The sewage leakage prevention device of claim 1 is a sewage leakage prevention device that prevents leakage of sewage from a gap between a toilet body and a toilet seat of a seated toilet, the sewage leakage prevention device has a substantially band-shaped sewage receiving part that receives sewage, an attachment part that detachably attaches the sewage receiving part to the toilet body, and an attachment holding part that holds the attachment position of the attachment part, the sewage receiving part has at least one or more gap holding parts that can form a gap for draining sewage between the sewage receiving part and the inner periphery of the toilet, and the upper end of the sewage receiving part is flat the sewage receiving portion can be installed inside the outer peripheral edge of the toilet body when viewed from the top, and above the height of the upper end of the toilet body when viewed from the side, the lower end of the sewage receiving portion can be installed inside the inner peripheral edge of the toilet body when viewed from the top, and below the height of the upper end of the toilet body when viewed from the side, and the sewage received in the sewage receiving portion can be caused to flow down the inner surface of the sewage receiving portion, and the sewage that exceeds the sewage receiving portion can be caused to flow down the gap portion for draining sewage, The present invention is characterized in that a part or all of the mounting part is placed on the upper surface of the toilet bowl, the position of the mounting part is changeable on the upper surface of the toilet bowl, the substantially horizontal position of the wastewater receiving part is changeable, and the mounting holding part holds the position of the mounting part or holds the mounting part at a position within a certain range on the upper surface of the toilet bowl, The sewage leakage prevention device prevents sewage from spilling out through the gap and leaking, and prevents leakage from the sewage leakage prevention device onto the top surface and outer surface of the toilet bowl, and sewage does not accumulate in the sewage leakage prevention device itself.Furthermore, the position of the sewage receiving part can be adjusted approximately horizontally, making it easier to adjust the front-to-back position of the sewage receiving part relative to the toilet seat, and it can be held in place to prevent it from shifting or falling after installation, making it compatible with a wider variety of seat-type toilets and effectively preventing sewage leakage.

[0013] Similarly, because the sewage leakage prevention device allows for easy adjustment of the front-to-back position of the sewage receiving section relative to the toilet seat, it is possible to provide measures against sewage leakage that suit the different needs of people using the same seated toilet and in different situations, such as dealing with severe leakage or dealing with minor leakage while maintaining a balance with appearance.

[0014] In the sewage leakage prevention device of claim 2, when a user sits on the toilet seat during sitting-down urination, the adjustment part bends or compresses in accordance with the gap between the toilet body of the seat-mounted toilet and the toilet seat, allowing the heightwise position of the sewage receiving part to be easily and appropriately adjusted, making it possible to accommodate a variety of gaps in a wider variety of seat-mounted toilets and thereby preventing sewage leakage even more effectively.

[0015] Similarly, since the height position of the sewage receiving portion of the sewage leakage prevention device can be easily and appropriately adjusted, even if a situation continues in which the sewage leakage prevention device is left in place and cleaning is not possible, sewage is efficiently flushed into the toilet bowl and sewage does not accumulate in the sewage leakage prevention device, which further effectively prevents sewage leakage, making it highly convenient in public toilets, etc.

[0016] Similarly, the sewage leakage prevention device allows the position of the sewage receiving section to be easily adjusted, and can continue to effectively prevent sewage leakage, eliminating the need for users to set up and dispose of the device before and after defecation, and there is no need to worry about the device becoming unusable due to a lack of consumables, allowing users to use the toilet steadily and comfortably, making it highly likely that the device can be used in public toilets, etc.

[0017] Similarly, the sewage leakage prevention device has a structure that does not accumulate sewage and can be easily adapted to fit the gaps of a variety of seated toilets, making it possible to clean it by simply washing it away with the sewage leakage prevention device left in place, and significantly reducing the time and effort required for cleaning, thereby reducing the costs incurred in keeping the toilet clean and allowing time to be spent on more valuable things, thereby making a broader contribution to society.

[0018] Similarly, the sewage leakage prevention device is designed not to accumulate sewage and can significantly reduce the time required for cleaning, thereby reducing the time that people who want to use the toilet have to wait while it is being cleaned, which may encourage its introduction in public toilets and contribute to a society where people can use the toilet comfortably even when they are out and about.

[0019] Similarly, the sewage leakage prevention device is structured so as not to accumulate sewage, and since it is attached to the toilet bowl, it does not prevent the toilet seat from being raised when used, and is therefore highly likely to be usable in public toilets, etc.

[0020] In the sewage leakage prevention device of claim 3, a connecting portion is provided that enables multiple sewage receiving portions to be connected together, and the length of the connected sewage receiving portions can be adjusted.This makes it possible to meet the desired length of the sewage receiving portion without having to manufacture products of multiple lengths individually, and the product size can be made compact, making it possible to provide a sewage leakage prevention device at low cost, thereby promoting measures to prevent sewage leakage.

[0021] Similarly, in the sewage leakage prevention device of claim 3, a connecting portion is provided that enables multiple sewage receiving portions to be connected together, and the connecting portion makes it possible to adjust the opening angle of the sewage receiving portions on both sides of the connecting portion according to the shape of the inner edge of the toilet body, making it easy to accommodate a variety of shapes of seated toilets and enabling the sewage leakage prevention device to be provided at low cost, thereby promoting measures against sewage leakage.

[0022] Similarly, a connecting portion is provided that enables multiple sewage receiving portions to be connected together, and the connecting portion makes it possible to adjust the opening angle of the sewage receiving portions on both sides of the connecting portion according to the shape of the inner edge of the toilet body. This means that consumers no longer need to worry about product selection due to differences in shape and size of seated toilets, and can easily introduce sewage leakage prevention devices.

[0023] In the sewage leakage prevention device of claim 3, the connecting part is configured so that the sewage receiving part is connected as a single unit and has a foldable folding part, which makes it possible to manufacture the device from a thin sheet-like material, making the product size very compact and providing a sewage leakage prevention device at low cost.

[0024] Similarly, in the sewage leakage prevention device of claim 3, the joint structure provided at both ends of each of the multiple sewage receiving sections is characterized by having a detachable connecting means, so that consumers can easily introduce sewage leakage prevention starting from the smallest size, and additional sewage receiving sections can be connected depending on the sewage leakage situation, making it highly convenient.

[0026] An embodiment of the present invention will be described with reference to the drawings. EXAMPLES

[0027] A first embodiment of the present invention will be described with reference to Fig. 1 to Fig. 4. Fig. 1 is a perspective view showing the embodiment of the present invention, Fig. 2 is a plan view of Fig. 1, Fig. 3 is a cross-sectional view taken along line A-A in Fig. 1, and Fig. 4 is a cross-sectional view taken along line B-B in Fig. 1.

[0028] The seat-type toilet 500 comprises a toilet body 30 and a toilet seat 40, and the toilet seat 40 has a generally O-shaped opening 41. The toilet seat back surface 44 forms a flat surface between an inner peripheral edge 42 and an outer peripheral edge 43, and an appropriate number of legs 45 are fixed to the toilet seat back surface 44. A gap 50 exists between the toilet body 30 and the toilet seat 40.

[0029] It should be noted that the illustrated seat-type toilet 5 is merely an example, and the shape of the toilet body 30 may be different, the shape of the toilet seat 40 may be different, such as U-shaped, and it may be a seat-type toilet with a function for washing human private parts, or it may be a portable toilet for nursing care.

[0030] The sewage leakage prevention device 1 comprises a belt-shaped sewage receiving portion 10 for receiving sewage, and an attachment portion 20. Note that the number of attachment portions 20 shown in the figure is an example, and is not limited to this number.

[0031] The sewage receiving portion 10 is formed by forming a band-shaped member into an arc, and is provided with a gap retaining portion 22 that enables a gap portion 6 for sewage drainage to be formed between the inner peripheral edge 32 of the toilet 30, and the upper end 11 of the sewage receiving portion 10 is formed so as to have a semicircular cross section, and can be installed inside the outer peripheral edge 33 of the toilet body 30 in a plan view, and can be installed above the height of the upper end 34 of the toilet body 30 in a side view, and the lower end 12 of the sewage receiving portion 10 can be installed inside the inner peripheral edge 32 of the toilet body 30, and can be installed below the height of the upper end 34 of the toilet body 30 in a side view.

[0032] The mounting part 20 consists of an arm part 24 which connects to the front 51 of the toilet body 30, an arm part 21 which connects to the side 52 of the toilet body 30, and a gap retaining part 22 which connects the arm part 24 and the arm part 21 to a part of the lower end 12 of the wastewater receiving part 10.

[0033] The arm portion 24 is a thin rod-like member formed into a roughly rectangular shape and placed in contact with the toilet upper surface 35, so that its position can be changed along the upper surface 35 of the toilet body 30. Both ends 25 of the arm portion 24 are respectively connected to the gap retaining portion 22 and connected to a part of the lower end 12 of the wastewater receiving portion 10 at a distance, and a gap portion 90 for draining wastewater is formed between the wastewater receiving portion 10 and the inner surface 37 of the toilet body 30. Further, a non-slip member 27 having a tubular shape with a slit in the longitudinal direction is fitted to the tip end 26 of the arm portion 24 as an attachment holding portion 80 .

[0034] The arm portion 21 consists of a wide member roughly U-shaped and is in contact with the upper surface 35 and outer surface 36 of the toilet body 30, and the gap retaining portion 22 consists of two narrow members and is respectively connected to the corners 23 of the inner surface of the arm portion 21, and connects to and holds a portion of the lower end 12 of the sewage receiving portion 10, forming a gap portion 90 for draining sewage between the sewage receiving portion 10 and the inner surface 37 of the toilet body 30.

[0035] The shape of the wastewater receiving portion 10 is not limited to that described above. For example, the wastewater receiving portion 10 may be circular and extend around the entire inner peripheral edge 32 of the toilet body, and the cross section of the upper end 11 of the wastewater receiving portion 10 does not have to be semicircular.

[0036] Regarding the shape and structure of the mounting part 20, due to the shape of the arm parts 24 and 22, the position of the wastewater receiving part 10 can be adjusted in the front-to-rear direction of the toilet seat 40 on a substantially horizontal plane. Although not limited to this example, in order to make it possible to change the position of the mounting part 20 on the top surface 35 of the toilet 30, at least the arm part attached to the center of the front 51 of the toilet body 30 is limited to the surface that comes into contact with the toilet body 30 on the top surface 35 of the toilet body 30 as in this embodiment, and does not come into contact with the outer surface 36 of the toilet body 30, which is advantageous for toilet assistance, etc. Other than that, the shape of the part that is placed on top surface 35 of toilet body 30, and for arm parts that are attached other than to the center of front 51 of toilet body 30, the shape and number, including the part that comes into contact with toilet body 30, may be different, and the method of attaching sewage leakage prevention device 1 to toilet body 30 may be different; for example, the part that is placed on top surface 35 of toilet body 30 may be a wide sheet-shaped arm part, and the back surface of arm part 24 may be made of a material that has mild adhesiveness.

[0037] The shape and specifications of the non-slip feature 27 are not limited to this embodiment, and the arm portion 24 and the arm portion 22 may have a non-slip feature in all or part, or a different non-slip feature may be provided on each of the multiple arm portions. In the case where no non-slip feature is provided, as shown in Figure 5 described below, a separate attachment holder 80 may be provided, and for example, the attachment holder 80 may be attached to the upper surface 35 of the toilet body 30 rather than to the arm portion, and may be provided as a stopper to prevent the arm portion from shifting in position on the upper surface 35 of the toilet body 30.

[0038] In addition, the position of the mounting portion 21 is near the center in the front-to-rear direction of the toilet top surface 35 in a plan view so as to minimize interference with the legs 45 of the bottom surface 44 of the toilet seat 40, but this is not limited to this example, and for example, the mounting portion 21 may be positioned toward the rear or front of the toilet top surface so that the arm portion 21 is located below the legs 45 of the toilet seat bottom surface 44. Furthermore, the sewage leakage prevention device 1 may be subjected to other treatments such as water repellent treatment, antibacterial treatment, and stain resistant treatment, without any particular limitation.

[0039] Regarding the material, the slip stopper 27 is made of silicone resin having flexibility and slip-stopping function, but other materials such as elastomer resin are not particularly limited. The entire sewage leakage prevention device 1 except for the slip stopper is made of polypropylene resin having flexibility, but the material is not limited to this example, and may be, for example, a resin material such as silicone resin or elastomer resin having flexibility and flexibility, or a fiber material such as paper or cloth that has been waterproofed. The materials of the sewage receiving part 10 and the mounting part 20 may be different, and for example, a metal material such as stainless steel may be used for a part of the mounting part 20, but the sewage receiving part 10 is preferably made of a resin having flexibility or elasticity, which is easy to adapt to various types of seated toilets and takes into consideration the safety of the user when the sewage receiving part 10 touches the body.

[0040] The size of the wastewater receiving part 10 is about 3.5 cm to 5 cm in height, about 30 cm to 50 cm in length, and about 1 mm to 2 mm in thickness, but is not limited to this example. The holding part 22 of the mounting part 20 is about 5 mm to 1 cm in width, about 5 mm to 2 cm in length, and the mounting part 21 is about 4 cm to 5 cm in width, about 1 cm to 2 cm in length of the part that contacts the inner surface 32 of the toilet body, and about 2 cm to 4 cm in length of the part that contacts the outer surface 36 of the toilet body, but is not limited to this example.

[0041] The arm portion 24 of the mounting portion 20 is a rod-shaped member with a diameter of about 3 mm to 6 mm, and the rectangular portion that contacts the upper surface 35 of the toilet body is about 2 cm to 4 cm wide and 3 cm to 4 cm long, but this is not limited to this example. The non-slip surface 27 is about 0.5 mm to 1 mm thick, and about 1 to 3 cm long in accordance with the width of the arm portion 24, but this is not limited to this example, and for example, most of the arm portion 24 may be covered with a material that has a non-slip function.

[0042] The sewage leakage prevention device 1 having the above configuration is provided with a gap retaining portion 22 that enables the formation of a gap portion 6 for draining sewage, and therefore prevents sewage from spurting out and leaking from the gap 50 between the sewage receiving portion 10 and the toilet bowl 40, prevents sewage from leaking along from the sewage leakage prevention device 1 to the upper surface 35 of the toilet bowl 40 and the outer surface of the toilet bowl 40, and prevents sewage from accumulating in the sewage leakage prevention device itself. Furthermore, since the position of the sewage receiving part can be adjusted approximately horizontally, it becomes easier to adjust the front-to-back position of the sewage receiving part relative to the toilet seat, and it can be held in place to prevent it from shifting or falling off after installation, making it compatible with a wider variety of seated toilets and effectively preventing sewage leakage.

[0043] Similarly, the sewage leakage prevention device 1 allows easy adjustment of the front-to-rear position of the sewage receiving portion 10 relative to the toilet seat 40, making it possible to provide sewage leakage countermeasures that meet the different needs of people using the same seated toilet and in different situations, such as dealing with severe leakage or dealing with minor leakage while maintaining a balance with the appearance.

[0044] Since the arm portion 24 is placed on the upper surface 35 of the toilet body 30 and the position of the arm portion 24 can be adjusted on the upper surface 35 of the toilet 40, the approximately horizontal position of the sewage receiving portion 10 can be changed, making it possible to accommodate a wider variety of seat-type toilets.It also makes it possible to easily accommodate a variety of positional relationships between the toilet seat and the toilet, such as when the inner periphery of the toilet bowl is located more inward than the inner periphery of the toilet seat, which was previously difficult to address, and effectively prevents sewage leakage.

[0045] Similarly, by providing the arm portion 24 in the center of the front 51 of the toilet bowl 30, it does not interfere with the legs 45 of the toilet seat bottom 44, and since the arm portion 24 does not protrude from the outer surface 36 of the toilet body 30, the arm portion 24 does not get caught when assisting the user with using the toilet, etc., and it is easy to accommodate a variety of seat-type toilets.

[0046] Similarly, since the sewage receiving portion 10 of the sewage leakage prevention device 1 is formed from a flexible material, the degree of opening of the arc of the sewage receiving portion 10 can be adjusted to a certain extent, and since the arm portion 21 of the mounting portion 20 which is attached to the side 52 of the toilet body 30 is U-shaped, it can be easily fitted and fixed onto the upper surface 35 of the toilet body 30, and can be adapted to a variety of toilet shapes and sizes.

[0047] Similarly, since the sewage leakage prevention device 1 has the above-mentioned effects and is designed to be installed on a toilet bowl, even when installed in a public toilet, it can be used by lifting the toilet seat, making it possible to prevent sewage leakage without compromising convenience.

[0048] Similarly, the sewage leakage prevention device 1 allows the position of the sewage receiving section to be easily adjusted, and can continue to effectively prevent sewage leakage, eliminating the need for the user to perform tasks such as installation and disposal before and after defecation, eliminating the need to worry about the device becoming unusable due to a lack of consumables, and allowing the toilet to be kept clean at all times, allowing users to use the toilet safely and comfortably, and therefore making it highly likely that the device can be used in public toilets, etc.

[0049] Similarly, the sewage leakage prevention device 1 has a structure that does not accumulate sewage and can be easily adapted to fit the gaps of a variety of seated toilets, making it possible to clean by simply washing away the sewage leakage prevention device while it is installed. This significantly reduces the time and effort required for cleaning, allowing time to be spent on more valuable tasks, and also significantly reduces the costs of maintaining and managing toilets, thereby making a broad contribution to society.

[0050] Similarly, the sewage leakage prevention device is designed not to accumulate sewage and can significantly reduce the time required for cleaning, thereby reducing the time that people who want to use the toilet have to wait while it is being cleaned, which may promote the introduction of measures to prevent sewage leakage in public toilets and contribute to a society where people can use the toilet comfortably even when they are out and about. EXAMPLES

[0051] An embodiment of the present invention will be described with reference to Fig. 5. Components common to the first embodiment are given the same reference numerals and their description will be omitted. Fig. 5 is a plan view showing a second embodiment of the present invention.

[0052] FIG. 5 shows an example in which the mounting and holding portion 80 in the first embodiment is a rectangular parallelepiped stopper 81, which is fixed to the top surface 35 of the toilet body 30 with adhesive tape. The position of the stopper 81 is within the range from the outer peripheral edge 43 to the inner peripheral edge 32 at the front 38 of the upper surface 35 of the toilet body 30, and after confirming the position of the stopper 81 corresponding to the position where the arm portion 24 can be stably placed, the stopper 81 is affixed and fixed with adhesive tape.

[0053] The shape and structure of the stopper 81 and the method of attaching it to the top surface 35 of the toilet body 30 are not limited to this example; for example, the stopper 31 may be hook-shaped and fixed to the top surface 35 of the toilet body with a suction cup so as to be hooked onto the mounting part 20, or it may be combined with elastic rubber or the like; there are no particular limitations.

[0054] The body of stopper 81 is made of polypropylene resin, which is resistant to chemicals and dirt, and the adhesive tape is made of acrylic resin, but this is not limited to this example. In addition to a suction cup, one side of a foldable member may be fixed and used upright only when necessary, and there is no particular limitation to this. EXAMPLES

[0055] An embodiment of the present invention will be described with reference to Figs. 6 and 7. Components common to the first and second embodiments are given the same reference numerals and their description will be omitted. Fig. 6 is a plan view showing a form of a third embodiment of the present invention, and Fig. 7 is a perspective view of the same embodiment.

[0056] In the sewage leakage prevention device 3, the gap retaining portion 22 in the sewage leakage prevention device 1 is made of a flexible material in the shape of a gently curved rod so that it also serves as the adjustment portion 80, forming a curved adjustment portion 83. The curved adjustment portion 83 is connected to a part 15 slightly outside the left-right center of the lower end 12 of the sewage receiving portion 10, and the curved adjustment portion 83 forms a slightly obtuse angle with the sewage receiving portion 10 in a plan view, dispersing the load on the curved adjustment portion 83 and allowing for an adjustment range.

[0057] The material for the anti-slip member 27 is silicone resin which has flexibility and anti-slip properties, while the rest of the sewage leakage prevention device 3 is made of flexible polypropylene resin; while this is not limited to this example, since the curved adjustment section 83 allows the position of the sewage receiving section 10 in the height direction to be adjusted and also allows the position in the approximately horizontal direction to be adjusted, a material which is not only flexible but also lightweight is desirable so that the sewage leakage prevention device 3 does not fall into the opening 41 of the toilet body 40 under its own weight; and other than resin, materials such as bamboo, wood, and waterproofed paper are also usable, without any particular limitation.

[0058] In addition, regarding the shape of the curved adjustment portion 83, in this embodiment it is a shape that includes a gentle curve, but this is not limited to this, and the cross section of the rod-shaped member of the curved adjustment portion 83 may be a circle or a polygon, or it may be a spiral shape or a shape with unevenness so that it has flexibility and elasticity, and is not particularly limited to this.

[0059] Furthermore, the curved adjustment portion 83 may be made of a different material that is more elastic and flexible than the wastewater receiving portion and the arm portion, such as resin, metal, rubber, etc., and the functions of the gap retaining portion 22 and the adjustment portion 80 may be formed by separate components, and there are no particular limitations. The size of the rod-shaped member of curved adjustment portion 83 is about 3 mm to 6 mm in diameter and about 2 cm to 6 cm in length, but is not limited to this example.

[0060] The sewage leakage prevention device 3 configured as described above has a curved adjustment portion that bends in accordance with the gap 90 between the toilet body 30 of the seat-type toilet and the toilet seat 40 when the user sits on the toilet seat 40 during sitting-down urination, and the heightwise position of the sewage receiving portion 10 can be easily and appropriately adjusted, making it possible to accommodate the various gaps of a wider variety of seat-type toilets and effectively preventing sewage leakage.

[0061] Similarly, since the sewage leakage prevention device 3 can effectively prevent sewage leakage, even if a situation continues in which the sewage leakage prevention device 3 is installed and cannot be cleaned, sewage can be efficiently flushed into the toilet bowl, and sewage does not accumulate in the sewage leakage prevention device, making it highly convenient in public toilets, etc. This embodiment is preferable because it has a simple structure, is easy to clean, and does not impair the appearance.

[0062] Similarly, the sewage leakage prevention device 3 allows the position of the sewage receiving section to be easily adjusted, and can continue to effectively prevent sewage leakage. Therefore, unlike disposable products, users do not need to set up or dispose of the device before and after defecation, and there is no need to worry about the device becoming unusable due to a shortage of consumables. As a result, users can use the toilet stably and comfortably, and it is highly likely that the device can be used in public toilets, etc.

[0063] Similarly, the sewage leakage prevention device has a structure that does not accumulate sewage and can be easily adapted to fit the gaps of a variety of seated toilets, making it possible to clean it by simply washing it away with the sewage leakage prevention device left in place, and significantly reducing the time and effort required for cleaning, thereby reducing the costs incurred in keeping the toilet clean and allowing time to be spent on more valuable things, thereby making a broader contribution to society.

[0064] Similarly, the sewage leakage prevention device 3 has a structure that does not allow sewage to accumulate, and the time required for cleaning can be significantly reduced, thereby reducing the time that people who want to use the toilet have to wait while the toilet is being cleaned. This may encourage its introduction in public toilets, and contribute to a society where people can use the toilet comfortably even when they are out and about.

[0065] Similarly, the sewage leakage prevention device 3 has a structure that does not allow sewage to accumulate, and since it is attached to the toilet, it does not prevent the toilet seat from being raised when used, and is therefore highly likely to be usable in public toilets, etc. EXAMPLES

[0066] An embodiment of the present invention will be described with reference to Fig. 8 and Fig. 9. Components common to Examples 1, 2, and 3 are given the same reference numerals and their description will be omitted. Fig. 8 is a plan view showing an embodiment 4 of the present invention, and Fig. 9 is a cross-sectional view taken along line C-C in Fig. 8.

[0067] The sewage leakage prevention device 4 is an example in which an adjustment part 60 is connected to the arm part 24 in the sewage leakage prevention device 1. The adjustment part 60 is composed of an elastic spring part 61 and a substantially sector-shaped bottom surface 62 and top surface 63, one end 65 of the spring part 61 is inserted into a part of the top surface 63, and the other end 64 is inserted into a part of the bottom surface 63 to connect them, and the bottom surface 63 is placed on the upper surface 35 of the toilet body 30. The illustrated arm section and adjustment section are merely examples, and the number and shape are not limited to these examples. There may be a plurality of arm sections and adjustment sections, and for example, the shape of the arm section 24 may be a wide sheet-like shape, may have an uneven upper portion, or may be formed of a frame, net, or the like instead of a flat surface.

[0068] The method of adjusting the height position of the sewage receiving portion 10 by the adjustment portion 60 is such that when the toilet seat 40 is lowered onto the toilet bowl 30 or when a user sits on the toilet seat 40 to urinate in a seated position, the upper end portion 11 of the sewage receiving portion 10 or the top surface 62, which is the upper end portion 67 of the arm portion 24 and the adjustment portion 60, is pressed against the bottom surface 44 of the lowered toilet seat 40, and / or the arm portion 24 and the bottom surface 63 of the adjustment portion 60 are pressed against the top surface 35 of the toilet bowl 30, thereby adjusting the sewage receiving portion 10 to a height that corresponds to the distance between the bottom surface 44 of the toilet seat 40 and the top surface 35 of the toilet bowl 30.

[0069] Regarding the material, the spring 61 of the adjustment part 60 is a spiral spring made of polycarbonate resin which has a biasing force in the extension direction, but this is not limited to this example, and a material or shape which has elasticity or flexibility is desirable, and for example, other resins, metals such as stainless steel or iron, coil springs, leaf springs, and other springs may be used, or sponge rubber such as silicone or chloroprene rubber which has elasticity and waterproofness may be used, and further, the range of height adjustment may be increased by combining this with other shape innovations such as inserting a wedge-shaped sponge rubber, and there is no particular limitation.

[0070] The bottom surface 63 is made of silicone resin, but other materials such as elastomer resin, ABS resin, etc., fiber materials such as wood and bamboo, and metal materials such as stainless steel, etc., are not particularly limited, but it is desirable that it can be stably installed on the top surface 35 of the toilet body 40, and if it does not have an anti-slip function or adhesiveness, it is desirable to provide an attachment holding portion 80, such as providing a stopper as in Example 2 described above.

[0071] The size of the top surface 62 and bottom surface 63 of the adjustment part 60 is about 4 to 8 cm wide, 3 to 4 cm long, and 1 mm thick, while the spring part 61 has an outer diameter of about 8 to 15 mm and a length of about 1 to 3 cm, but is not limited to this example. The top surface 62 and bottom surface 63 may be shaped to be placed widely on the top surface 35 of the toilet body 40, for example, or may be provided in multiple places.

[0072] In the sewage leakage prevention device 4 configured as described above, when the user sits on the toilet seat 40 during seated excretion, the spring portion 61 expands and contracts to a height corresponding to the gap 90 between the toilet body 30 of the seat-mounted toilet and the toilet seat 40, so that the heightwise position of the sewage receiving portion 10 can be easily and appropriately adjusted, making it possible to accommodate the various gaps of various seat-mounted toilets and effectively preventing sewage leakage in the same way as the sewage leakage prevention device 3. Compared to the sewage leakage prevention device 3, the sewage leakage prevention device 4 has more components and may not be as easy to clean, but depending on the materials and components, it may be possible to provide a similar sewage leakage prevention effect with a cheaper manufacturing method. EXAMPLES

[0073] An embodiment of the present invention will be described with reference to Figs. 10 and 11. Components common to Examples 1 to 4 are given the same reference numerals and their description will be omitted. Fig. 10 is a plan view showing a form of Example 5 according to the present invention. Fig. 11 is a perspective view showing a sewage leakage prevention device of the same example.

[0074] The sewage leakage prevention device 5 is a sewage leakage prevention device 1 in which connecting portions 200 are provided near both ends of the sewage receiving portion 10 in the longitudinal direction, and the connecting portions 200 are formed to have a joint structure that enables multiple sewage receiving portions 210 to be detachably connected. The connecting portion 200 provided on the sewage receiving portion 10 has a hole portion 201 that forms a long, narrow hole in the vertical direction, and the hole portion 201 is formed so that an insertion portion 211 of the connecting portion 200 provided at one end of the connecting sewage receiving portion 210 can be inserted into the hole portion 201 to enable detachable connection.

[0075] In addition, the connecting portion 210 provided at the other end of the sewage receiving portion 210 has a hole portion 201 that forms a vertically elongated hole, similar to the hole portion 201 of the sewage receiving portion 10 described above, and the length of the sewage receiving portion 210 when multiple pieces are connected together can be adjusted. Furthermore, the connecting portion 200 is formed so that the opening angle of the wastewater receiving portions 210 on both sides of the connecting portion 200 can be adjusted according to the shape of the inner peripheral edge 32 of the toilet body 40 .

[0076] The numbers and shapes of the wastewater receiving parts 10 and 210 shown in the figures are merely illustrative and are not limited to these examples. The lengths and shapes of the wastewater receiving parts may be different, and multiple wastewater receiving parts of different shapes may be combined. Although an example is shown in which the wastewater receiving portion 210 does not have an attachment portion, there may be wastewater receiving portions with attachment portions and wastewater receiving portions without attachment portions, and combinations may be made according to the situation, such as the state of the connected wastewater receiving portions, the position of the legs of the toilet seat of the seat-type toilet to be installed, and the shape of the toilet.

[0077] The direction of insertion into the connecting part is also shown as an example; for example, the upper ends of the sewage receiving parts may be connected so as to form a peak and a valley when viewed in a plane, and the opening angle of the sewage receiving parts 210 on both sides of the connecting part 200 can be adjusted according to the shape of the toilet and the usage conditions, and is not particularly limited.

[0078] The size of the wastewater receiving portion 210 is about 3.5 cm to 5 cm in height, about 10 cm to 30 cm in length, and about 1 mm to 2 mm in thickness, but is not limited to this example. The hole 201 of the connecting portion 200 is about 1 mm to 2 mm in size, and about 1.5 to 2 cm in length, but is not limited to this example. The material of the wastewater receiving portion 210 is polypropylene, but this is not limited to this example and may be resin such as silicone or elastomer, metal such as stainless steel, wood or bamboo, or cloth or paper that has been waterproofed. Although an example of the connecting part 200 being inserted into a hole is illustrated, the present invention is not limited to this example. For example, a pin may be inserted through each end to connect them, increasing the freedom of the opening angle of the wastewater receiving parts on both sides of the connecting part, or a protrusion may be provided and fitted into the connecting part, or the connecting part may be attached, and the present invention is not particularly limited to this example.

[0079] The sewage leakage prevention device 5 consisting of the above-mentioned has a connecting portion 200 that enables multiple sewage receiving portions to be connected, and makes it possible to adjust the length of the connected sewage receiving portions 210. Therefore, it is possible to meet the demand for products with long sewage receiving portions without having to manufacture products of multiple lengths individually, and since the product size can be made compact, it is possible to provide a sewage leakage prevention device at low cost, thereby promoting measures against sewage leakage.

[0080] Similarly, the sewage leakage prevention device 5 is provided with a connecting portion 200 that enables multiple sewage receiving portions 210 to be connected together, and the connecting portion 200 makes it possible to adjust the opening angle of the sewage receiving portions 210 on both sides of the connecting portion 200 according to the shape of the inner edge of the toilet body 30. This makes it easy to accommodate a variety of shapes of seated toilets, and enables the sewage leakage prevention device to be provided at low cost, thereby promoting measures against sewage leakage.

[0081] Similarly, a connecting portion is provided that enables multiple sewage receiving portions 210 to be connected together, and the connecting portion makes it possible to adjust the opening angle of the sewage receiving portions on both sides of the connecting portion according to the shape of the inner edge of the toilet body. As a result, consumers no longer need to worry about product selection due to differences in shape and size of seated toilets, and can easily introduce sewage leakage prevention devices and begin taking measures against sewage leakage.

[0082] Similarly, the sewage leakage prevention device 5 has a connecting part that allows multiple units to be connected together and is made to be adjustable in length, so that consumers can easily introduce sewage leakage prevention starting from the smallest size, and it is highly convenient because additional sewage receiving parts can be connected depending on the sewage leakage situation. EXAMPLES

[0085] The sewage receiving portion 110 has a connecting portion 115 that is folded in the short axis direction of the sewage receiving portion 110, forming a foldable folding portion. The connecting portion 115 is folded alternately in a mountain fold and a valley fold, and by adjusting the opening angle of the sewage receiving portions 210 on both sides of the connecting portion 115, the sewage receiving portion 110 can be installed according to the shape of the inner peripheral edge 37 of the toilet body. In addition, by adjusting the opening angle of the wastewater receiving portion 110 on both sides of the connecting portion 115, the length of the wastewater receiving portion can also be adjusted.

[0086] The shape of the wastewater receiving portion 110 is not limited to the above. For example, the entire wastewater receiving portion 110 may be circular and extend around the entire inner peripheral edge 35 of the toilet body 30, and the number of connecting portions 115 of the wastewater receiving portion 10 may be increased or decreased, and the shape does not have to be an alternating mountain fold and valley fold.

[0087] The shape and structure of the mounting portion 120 are not limited to those described above, and the shape of the protrusion 121 and the structure and shape of the mounting and holding portion 180 may be different. Furthermore, the sewage leakage prevention device 6 may be subjected to other treatments such as water repellent treatment, antibacterial treatment, and stain resistant treatment, without any particular limitation.
