Description

  The present invention relates to a toilet device having a waist rest.

  Conventionally, a toilet device as shown in FIG. In the conventional example shown in Patent Document 1, a bulge that serves as a waistrest 5 ′ protrudes from the back surface of a toilet lid 3 that is rotatably attached to the toilet 1, and the toilet lid 3 is raised and opened. When a person sits on the toilet seat 2, the hip rest 5 ′ protruding from the back of the toilet lid 3 hits the person's waist and keeps the posture of sitting straight with the back straight during defecation and stimulates the waist to promote defecation. Can be done.

  However, in the conventional example shown in FIG. 7 described above, when the toilet lid 3 is closed, the toilet lid 3 cannot be closed if the waist rest 5 ′ protruding from the back surface of the toilet lid 3 hits the toilet seat 2. Therefore, when closing the toilet lid 3, it is necessary to prevent the waist rest 5 'protruding from the back surface of the toilet lid 3 from hitting the toilet seat 2. For this reason, in the conventional example, the toilet seat on the back surface of the toilet lid 3 is required. 2 The waist rest 5 'is projected at a position not facing the upper surface, that is, a position facing the opening of the toilet seat 2 on the back surface of the toilet lid 3, and the waist rest 5' projected from the back surface of the toilet lid 3 is placed on the toilet seat 2. It is necessary to insert it into the opening of the door and let it escape.

  Conventionally, as described above, the protruding position of the waistrest 5 ′ is limited only to the central portion in the left-right direction at the bottom of the back surface of the toilet lid 3, so that the waist of the user sitting on the toilet seat 2 can be effectively used. There is a problem that it cannot be pushed stably.

  Moreover, when both the toilet lid 3 and the toilet seat 2 are stood up and opened for a boy's use, the bulge that is the waistrest 5 'is projected forward from the opening of the toilet seat 2 and is unsightly, There was a possibility that urine splashed on the waistrest 5 ′ protruding forward from the opening of the toilet seat 2, which was not hygienic.

In addition, Patent Document 2 discloses that a backrest is provided on the upper back of the toilet seat. However, the conventional example shown in Patent Document 2 is for a person sitting on the toilet seat to bend his back. The posture in which the back is drowned is not sufficient as a posture to promote defecation, unlike the posture of a straight seat in which the back of the person sitting on the toilet seat is pushed and the back is stretched during defecation.
