Description

[Technical Field]

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

[0002] Generally, a seat-type 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 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's private parts cleansing function. Hereinafter, the urine and cleaning water leaking from the gap in a seat-type toilet will be referred to simply as wastewater.

[0003] As a method for solving the problem of sewage leakage, Patent Document 1 describes a method for attaching a strip-shaped sewage receiving part to the toilet bowl, forming a gap between the part and the toilet bowl, so that sewage that exceeds the top of the sewage receiving part can flow down through the gap, preventing leakage along the toilet and preventing sewage from accumulating 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 toilet bowls of various shapes and gap sizes. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-234767 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in Patent Document 1, the sewage catcher must be properly positioned and at the right height to effectively prevent sewage leakage. This poses a challenge: it is difficult to balance the flexibility required to accommodate a variety of seated toilets with maintaining the proper position during actual use. For example, while using a linear metal member for the attachment allows for a high degree of adjustment, the gap between the toilet bowl and the seat is difficult to see, making it difficult for users to adjust and install the device to fit a variety of seated toilets. Furthermore, even when the attachment is properly installed, complaints have been received that the attachment may shift or the height of the sewage catcher may change as the seated toilet is used, resulting in sewage leakage. Furthermore, when the sewage catcher is removed for cleaning the toilet, the adjusted shape may be distorted, requiring readjustment, which has also been unpopular.

[0006] Furthermore, there has been a demand for a product with a wastewater collection area that extends to the rear of the toilet bowl, not just the front, but also the rear of the bowl, but including the rear of the bowl increases the variety of shapes, making it even more difficult to accommodate, and there are issues with the cost of manufacturing a large product separately, and with the increased storage space and shipping costs involved for sales, making it an unaffordable price. Furthermore, depending on the usage situation, there is the issue of wanting a setting that effectively prevents leaks even if the wastewater collection area is somewhat noticeable only when used by people who require care and who leak frequently, and in other cases wanting a less noticeable wastewater collection area to prioritize easier cleaning, and so on, and there is also the issue of not being able to meet the different needs of different people and situations when using the same seated toilet.

[0007] Unfortunately, most commercially available sewage leak prevention products are limited to seated use due to installation location and appearance issues, limiting their use to homes and other environments where the parties involved can understand the situation. In fact, very few public restrooms are designed to prevent sewage leaks, making them prone to leaks. This not only hinders user comfort, but also increases the burden on cleaning staff, who are forced to spend time cleaning toilets while reducing their essential duties amidst labor shortages, which is considered a significant social loss. Furthermore, while seated toilet use has been increasing in recent years, opportunities for lifting the toilet seat will remain. It is necessary to consider the fact that there are other uses besides standing, such as flushing diapers or vomiting. It is desirable to have sewage leak prevention devices that are both convenient and psychologically acceptable in public spaces.

[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.

[0032] The mounting portion 20 includes an arm portion 24 connected to the front 51 of the toilet body 30, and an arm portion 21 connected to the side 52 of the toilet body 30. The gap retaining portion 22 is made up of: The arm portion 24 and the arm portion 21 are connected to a part of the lower end 12 of the wastewater receiving portion 10. do become.

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

[0034] The arm portion 21 consists of a wide member that is approximately 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 that are respectively connected to the corners 23 on the inner surface of the arm portion 21 and hold and connect to a portion of the lower end 12 of the sewage receiving portion 10, forming a gap portion 90 for discharging 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 the above, and for example, the wastewater receiving portion 10 may be circular and extend around the entire inner peripheral edge 32 of the toilet body, or the cross section of the upper end 11 of the wastewater receiving portion 10 may not be semicircular.

[0036] The shape and structure of the mounting part 20 are as follows: Arm part 21 Due to the shape of the toilet seat 40, the position of the wastewater receiving portion 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 the position of the mounting portion 20 changeable on the upper surface 35 of the toilet 30, at least the arm portion attached to the center of the front 51 of the toilet body 30 is required. 24Regarding this, as in this embodiment, the surface that comes into contact with the toilet body 30 is limited to the top surface 35 of the toilet body 30, and does not come into contact with the outer surface 36 of the toilet body 30, which is considered desirable from a practical standpoint as it does not cause any problems when assisting with using the toilet, and the shape and number of the part that is placed on the top surface 35 of the toilet body 30, and the part that comes into contact with the toilet body 30 for arm parts 21 that are attached other than the center of the front 51 of the toilet body 30, may be different, and the method of attaching the sewage leakage prevention device 1 to the toilet body 30 may be different; for example, the part that is placed on the top surface 35 of the toilet body 30 may be a wide sheet-shaped arm part, or a material with mild adhesiveness may be used on the back surface of the arm parts 24.

Furthermore, there is no particular limitation to applying other treatments to sewage leakage prevention device 1, such as water-repellent, antibacterial, and stain-resistant treatments.

[0039] Regarding the material, the non-slip stopper 27 is made of silicone resin, which has flexibility and non-slip properties, but other materials such as elastomer resin are also not particularly limited. The entire sewage leak prevention device 1, excluding the non-slip stopper, is made of flexible polypropylene resin, but this is not limited to this example and may be made of, for example, a flexible and pliable resin material such as silicone resin or elastomer resin, or a fiber material such as waterproofed paper or cloth. The sewage receiving portion 10 and the attachment portion 20 may also be made of different materials. For example, a metal material such as stainless steel may be used for part of the attachment portion 20, but a flexible or elastic resin is desirable for the sewage receiving portion 10, as it can be easily adapted to a variety of seated toilets and is a consideration for safety when it comes into contact with the body.

[0040] The size of the wastewater receiving portion 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. Wastewater receiving section 10 of gap The holding portion 22 has a width of about 5 mm to 1 cm and a length of about 5 mm to 2 cm. Arm 21 is about 4cm to 5cm wide, inside the toilet bowl 37 The length of the portion in contact with the outer surface 36 of the toilet body is about 1 cm to 2 cm, and the length of the portion in contact with the outer surface 36 of the toilet body is about 2 cm to 4 cm, but the present invention is not limited to these examples.
