便座
Document Type and Number:
Japanese Patent JP7342633
Kind Code:
B2
Abstract:
The utility model provides a toilet seat which well disperses body pressure from ischial tuberosity and buttocks and further improves sitting feeling. The inner diameter side corner part and the outer diameter side corner part of the seating surface have convex arc-shaped outlines in a radial cross section when the toilet seat is sectioned by a plumb plane extending from the center of the inner hole to the radial direction. When the sectioning angle when the toilet seat is sectioned in a plumb plane extending forward from the center of the inner hole is set to be 0 degree, the radius of curvature of the inner diameter side corner portion in the radial cross section reaches the maximum value in the radial cross section when the sectioning angle is a specified angle larger than 130 degrees and smaller than 180 degrees, and the radius of curvature becomes smaller along with the distance from the specified angle. In addition, the seat surface angle, which is an angle formed by a straight line connecting arc ends close to an inner diameter side corner part and an outer diameter side corner part in a radial cross section, with respect to a horizontal line, is formed so as to increase as the cross section angle increases in a range of 90-180 degrees.
