Abstract

PROBLEM TO BE SOLVED: To provide a toilet seat of a stool in which the weight of a construction member of the toilet seat is lightened and in which material costs and the load when driven by an electric motor, are reduced. SOLUTION: A toilet seat is to receive the load of a user for stool seating on the toilet seat and is structured that, adjacent to or at the center of a leg part 17 installed on the bottom of a toilet seat back member 2 for a stool to be put fixedly, the load of an upper rib 8 installed on a toilet seat surface member 1 is received by a lower rib 9 installed on the toilet seat back member 2. The toilet seat can be lightened in its weight as the load can be distributed not only to the peripheral connecting part but also to the upper and lower ribs, compared with the structure of conventional models and the toilet seat surface and back members 1, 2 can be made thinner in thickness. As for a toilet seat driven by an electric motor, motorization in light weight is possible as the load on motor can be reduced with the reduction of the weight of the toilet seat.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat for a stool.

[0002]

2. Description of the Related Art As shown in a sectional view of FIG. 3, a conventional toilet seat structure used in a conventional stool type toilet seat has a plate-shaped toilet seat having a convex toilet seat surface member 1 forming the surface and side surfaces of the toilet seat. The back member 2 was bonded by the bonding surface 3, and a space 20 was formed inside the toilet seat. However, in this structure, although the leg portion 17 for supporting the toilet seat is provided at an appropriate position of the toilet seat back member 2, the load when the user sits on the toilet seat is applied to the toilet seat front member 1 and the toilet seat back member 2. Therefore, the toilet seat front member 1 and the toilet seat back member 2 constituting the toilet seat need to be thick in order to withstand the load.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems of the toilet seat used in the conventional stool type toilet. Another object of the present invention is to provide a toilet seat of a stool that can reduce the weight of a motor by reducing material costs while reducing the load on an electric toilet seat.

[0004]

A toilet seat according to the present invention is a toilet seat for a stool which is formed by bonding a peripheral portion of a toilet seat surface member forming a surface portion of a toilet seat and a peripheral edge portion of a toilet seat back member forming a back portion of the toilet seat. In the vicinity of a leg provided on the bottom of the toilet seat back member to be placed on the toilet, a lower rib is erected inside the toilet seat back member, and the upper rib abuts the lower rib inside the toilet seat front member. It is the gist that it was installed vertically.

[0005]

According to the present invention, an upper rib is provided on a toilet seat front member in the vicinity of a leg provided on the bottom of a toilet seat back member to be placed on a toilet in order to receive a load of a user sitting on the toilet seat. The load is received by the lower rib provided on the toilet seat back member, and the load can be distributed not only to the peripheral edge bonding portion but also to the upper rib and the lower rib as compared with the conventional structure, and the toilet seat front member and the toilet seat back member The wall thickness can be reduced and the weight of the toilet seat can be reduced. Further, in the electric toilet seat, the load on the motor can be reduced as the weight of the toilet seat is reduced, so that the weight of the motor can be reduced.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is an external perspective view of a toilet seat to which the present invention is applied, and FIG. 1 is a partial sectional view of a main part of the toilet seat of the present invention. In FIG. 1, the toilet seat front member 1 is a member that curves downward so as to form part of the surface and side surfaces of the toilet seat, and the toilet seat back member 2 is upward so as to form part of the rear surface and side surfaces of the toilet seat. The toilet seat having a space 20 inside is formed by fitting the adhesive surfaces of the peripheral portions of both members together.

[0007] A concave groove 1 is formed on the bonding surface of the peripheral portion of the toilet seat member 1.
0 is provided, and a locking portion 13 protrudes from the inner surface of the concave groove 10. A groove 1 is provided on the bonding surface of the two peripheral portions of the toilet seat back member.
0 is provided, and a concave portion 14 in which the locking portion 13 of the concave groove 10 is fitted and a claw portion 7 which is engaged with the corner 13a of the locking portion 13 are provided adjacent to the convex ridge 11. Locking piece 15 having
Is provided. Note that the claw portion 7 has an inclined surface 16 that becomes thinner toward the tip, and when the ridge 11 is fitted into the concave groove 10, the locking portion 13 of the concave groove 10 is inclined by the locking piece 15. Because it contacts the surface 16 and deflects the locking piece 15 inward,
The locking portion 13 can be easily fitted into the concave portion 14.

[0008] Further, the toilet seat back member 2 for placing on the toilet bowl.
A lower rib 9 is erected inside the toilet seat back member 2 in the vicinity of the leg 17 provided at the bottom of the toilet seat, and the upper rib 8 is attached to the toilet seat front member 1 so that the lower rib 9 receives a load. 9, the load is applied to the toilet seat when the user sits down.

When assembling the toilet seat of the present embodiment, the ridge 11 of the toilet seat back member 2 is positioned in the concave groove 10 of the toilet seat front member 1 and pressed. Since the locking piece 15 comes into contact with the inclined surface 16 and bends inward, the locking portion 13 easily fits into the concave portion 14. When the locking portion 13 is fitted into the concave portion 14, the locking piece 15 is restored to the original position, so that the corner 13 a of the locking portion 13 is fixed by the claw 7 of the locking piece 15. Also, when the toilet seat front member 1 and the toilet seat back member are assembled, the upper rib 8 comes into contact with the lower rib 9 and the load applied to the toilet seat when the user sits on the toilet seat is supported.

[0010]

According to the present invention, in order to receive the load of the user sitting on the toilet seat, an upper rib is provided on the toilet seat front member in the vicinity of a leg provided on the bottom of the toilet seat back member for mounting on the toilet. And the load is received by the lower rib provided on the toilet seat back member. Compared with the conventional structure, the load can be distributed not only to the peripheral edge bonding portion but also to the upper rib and the lower rib. The thickness of the back member can be reduced, and the weight of the toilet seat can be reduced. Further, in the electric toilet seat, the load on the motor can be reduced as the weight of the toilet seat is reduced, so that the weight of the motor can be reduced.
