  However, since the above-mentioned conventional raised toilet seat has a flange of a specific size formed integrally with the main body portion, the toilet seat with an opening of a size that can contact the flange of the raised toilet seat is formed. Only when it is mounted, it is positioned and fixed with respect to the toilet seat. On the other hand, there are generally large, standard, and common toilet seats depending on the physique of the user, and these have large and small openings.

  For this reason, a person who wants to purchase an elevated toilet seat must purchase an elevated toilet seat having a flange adapted to the toilet seat being used. If you purchase a raised toilet seat with a flange that does not fit the toilet seat, the size of the toilet seat opening and the height of the raised toilet seat do not match, and the gap between the flange and the inner edge of the opening In many cases, there was a problem of looseness. In this case, a weak person such as an elderly person is not stable in sitting posture and is dangerous. This problem is also affected by the fact that the toilet seat used for nursing care is rarely purchased as an accessory of a Western-style toilet together with the Western-style toilet.

  In addition, the manufacturer must prepare a raised toilet seat according to the type of toilet seat, resulting in an increase in manufacturing cost.

  The present invention has been made in view of the above-described conventional circumstances, and can be stably seated even if a user uses a toilet seat having an opening of various sizes, and the manufacturing cost is also increased for the manufacturer. It is an issue to be solved to provide a raised toilet seat that does not cause any changes.

The elevated toilet seat according to the present invention is provided on a western style toilet and is placed on a toilet seat in which an O-shaped or U-shaped opening is formed in the center, and the seated surface is higher than the toilet seat. ,
A main body that can abut on the toilet seat; a side wall extending from the inner edge or outer edge of the main body toward the toilet seat; and a biasing unit that applies a biasing force to the main body or the side wall.
Each of the main body portions is formed in a semicircular shape and includes a pair of arcuate bodies each having one end swingably coupled to each other, and the energizing means that energizes the arcuate bodies in a direction away from or approaching each other. The urging force of the toilet seat is pressed and fixed to the inner edge or the outer edge of the toilet seat.

  The elevated toilet seat of the present invention having such a configuration is placed on the toilet seat so that the seating surface is higher than the toilet seat. For this reason, this elevated toilet seat is used, for example, for nursing care when a weak person such as an elderly person, a sick person, or a disabled person uses a Western-style toilet, and the user can easily operate when sitting on the Western-style toilet or standing up from the Western-style toilet. It is possible to improve comfort when using a Western-style toilet by improving the comfort of sitting or sitting.
