Description

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 sitting toilet, and in particular, it is made up of two members, a hard part and a soft part, to improve the usability when seated, and a design using two colors. Is related to the toilet seat that has been improved.

[0002]

2. Description of the Related Art Conventionally, the toilet seat of a seat-type toilet bowl is generally formed in a ring shape using wood or a synthetic resin material such as ABS. However, the toilet seat using these materials is hard and uncomfortable to sit on, and if sitting for a long time, the buttocks or legs are hurt or numb.
Also, in winter, the heat insulation was not good, so I felt a cold sensation and sometimes felt cold when I was sitting.

Therefore, in order to impart elasticity and heat insulation, for example, Japanese Utility Model Laid-Open No. 56-111892 and Japanese Utility Model Laid-Open No. 56-111893 disclose a technique for molding a toilet seat with urethane foam. . In addition, the actual development Sho 60-2
As disclosed in Japanese Patent No. 7799 and Japanese Utility Model Laid-Open No. 63-166100, there is disclosed a technique in which a toilet seat cover for covering the toilet seat is formed of foam resin.

However, if the toilet seat is made of only foam as described above, it cannot maintain a predetermined shape against the load of the human body when it is seated due to its low rigidity strength, and deformation such as wrinkles occurs. There is a possibility that it may warp and become uncomfortable to sit on.

As a solution to these problems, the base portion which is the supporting portion is made of a hard resin material to increase the overall rigidity and the contact portions such as the buttocks and legs are covered with foam. Further, there is one in which after coating the outside with a vinyl chloride sheet, this end is fixed by sewing or heat welding. However, in this case, in addition to the high cost,
It was not very good in appearance.

[0006] On the other hand, Japanese Utility Model Laid-Open No. 62-53091 discloses a technique in which a cushion body having a shape corresponding to the seat is detachably mounted on a toilet seat base to give a good feeling to the user. It is posted. According to this, it becomes easy to remove the cushion body that is easily soiled and to wash it, and it is possible to always keep it clean.

[0007]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
Since the external appearance of the toilet seat disclosed in Japanese Patent Laid-Open No. 53091, in which the cushion body is detachable, is integrally covered with the cushion body, the appearance color is monochromatic and the design is monotonous. In addition, although it is possible to use multiple colors by printing or the like, it does not have a three-dimensional effect and makes the user feel cheesy. It is also possible to cover the cushion body with a synthetic resin sheet, and mix or stick natural materials such as wood and grass to this sheet, but this not only complicates the material composition, but also allows it to be removed. It wasn't the only eye-catching, voluminous design.

By the way, when the toilet seat is made up of two members, a base portion and a skin contact portion, and the skin contact portion is detachable, the skin contact is caused by an impact when the toilet seat is opened or closed, or by rough handling. It is required that the part does not come off and that the part is stably held without being displaced when the user sits down.

Therefore, according to the present invention, by making the skin contact portion detachable while ensuring the required strength, it is possible to give the user a good feeling of use and to easily perform cleaning and replacement. It is an object of the present invention to provide a toilet seat that can improve the designability by dual-coloring the appearance portion by a member and that can stably hold the skin contact portion on the base portion during use and the like.

[0010]

The toilet seat according to the present invention comprises:
The inner peripheral side of the toilet seat is formed as a base portion and the outer peripheral side as a part of the design portion, and a rigid portion having a through hole formed in the base portion, and a detachable attachment to the rigid portion, a skin contact portion of the toilet seat. And a core member having a mounting portion corresponding to the through hole of the base portion of the hard portion, and a soft portion forming a soft portion forming the core portion, and inserted into the mounting portion of the core member. And a mounting tool for holding the rigid portion.

[0011]

In the present invention, since the base portion of the toilet seat is formed of the hard portion, the required strength as a whole is secured. Further, since the skin contact portion is formed by the soft portion, the user does not feel uncomfortable, numbness, and pain, and in the winter, the heat insulating action of the soft portion does not give a cold feeling. Furthermore, since the hard part can be held by inserting the locking part of the fixture from the through hole of the hard part into the mount part of the core member joined to the soft part, the soft part can be easily attached. In addition, it can be prevented from coming off due to impact at the time of opening and closing, rough handling, etc. On the other hand, the soft portion can be removed by removing the attachment. As a result, the skin adhesive portion can be replaced with a suitable one for the user, or a soiled or damaged product, and the skin contact portion, which is easily soiled, can be removed and easily cleaned. Then, since the hard part forming a part of the design part and the skin contact part and the soft part also serving as the design part can be formed in different colors, the degree of freedom in design design is increased and the designability is improved. .

Has been done. The plane shape of the skin contact surface 3c forming the taper surface is formed into a shape suitable when the user sits down.

That is, the soft part 3 constitutes a skin contact part where the buttocks and legs of the human body come into contact, and is foamed using a material such as urethane, soft vinyl chloride, TPR (thermoplastic rubber) or the like. Molded using the body, rubber hardness is 30
It is adjusted to be about 45 degrees.

Further, a metal plate such as an iron plate or an aluminum plate, or a core material 4 made of a hard resin or the like is joined to the bottom surface 3a and the outer peripheral surface 3b of the soft portion 3. The core member 4 is composed of a core member main body 5 having a substantially L-shaped cross section and a disc-shaped support plate 6, and the core member main body 5 is provided with a press or the like at the center of the horizontal plane, That is, the soft part 3
A cylindrical recess having two steps is formed on the side, and the support plate 6 is joined to the lower recess by spot welding at a position indicated by a mark X in FIG. . The upper side (bottom side) recess of the core body 5 forms a holding space 4a, which is an attachment portion for locking one end of the attachment 7 with the support plate 6. Further, an elongated rectangular hole 6a having substantially the same shape and size as the through hole 2d of the hard portion 2 is formed in the central portion of the support plate 6, and the rectangular hole 6a is formed.
A dowel 6b is formed in the peripheral portion of "a" for preventing displacement of the attachment 7. The core material 4 is joined to the soft part 3 by using a known means such as an adhesive, a double-sided tape or a screw, and the support plate 6 is joined to the core material body 5. When the support plate 6 is formed of a hard resin, it can be performed by adhesion with an adhesive or by welding such as ultrasonic welding or heat welding.

The fixture 7 has a rectangular plate-shaped engaging portion 7a, a pillar 7b, and a substantially hemispherical buffer which are substantially the same in shape as the through hole 2d of the hard portion 2 and the square hole 6a of the support plate 6. 7c and is formed using TPR, a synthetic resin material, or the like.

The hard portion 2 and the soft portion 3 can be formed in different color tones by arbitrarily selecting a colorant added to the material.

Next, the use of the toilet seat of this embodiment constructed as described above will be explained.

In order to mount the soft portion 3 on the hard portion 2, the soft portion 3 is placed at a predetermined position on the hard portion 2. Then, the square hole 6a of the support plate of the core material 4 joined to the bottom surface 3a of the soft portion 3 and the outer peripheral surface 3b is overlapped with the through hole 2d of substantially the same shape formed in the horizontal surface 2b of the hard portion 2. opposite. Therefore, the locking portion 7a of the fixture 7 is inserted from below in conformity with the shapes of the through hole 2d of the hard portion 2 and the square hole 6a of the core material 4. The locking portion 7a of the fixture 7 is the core body 5
When it is housed in the holding space 4a formed by the concave portion of the support plate 6 and the support plate 6, the fixture 7 is rotated 90 degrees in the direction of the double-dashed line arrow in the drawing to be positioned between the dowels 6b of the support plate 6. .
As a result, as shown in FIG.
The support plate 6 and the horizontal surface 2a of the hard portion 2 are held by the cushioning member 7c, and the soft portion 3 is attached to a predetermined position on the hard portion 2 so that the toilet seat 1 can be used.

In the toilet seat 1 to which the soft portion 3 is attached as described above, since the vertical surface 2b of the hard portion 2 is formed in an annular shape, its horizontal movement is restricted, and the soft portion 3
Since the skin contact surface 3c is a taper surface that is inclined downward from the outer peripheral side toward the inner peripheral side, when the buttocks and legs of the human body press the soft portion 3 downward, the soft portion 3 is elastically compressed in the outer peripheral direction, and the vertical surface 2 of the hard portion 2

Has a required rigidity, maintains a predetermined shape without being deformed by the pressing force even when the user sits down, and stably holds the soft portion 3 placed on the upper portion. .

On the other hand, since the soft part 3 which comes into contact with the buttocks and legs of the human body is formed of a foam such as urethane foam, the skin contact part is entirely contacted by its elastic force, and the local part The user does not feel uncomfortable because it is not pressed, and the user does not feel numbness or pain even after sitting for a long time. When the soft part 3 is molded with a foam such as urethane foam, a skin layer is formed on the surface thereof, and in particular, there is no discomfort to the touch, and
Water does not penetrate.

Further, due to the heat insulating effect of the foam, the cold feeling in the winter is eliminated and the foam can be used comfortably.

Various types of foam can be used for these purposes. Among them, urethane foam has a large strength, despite its light weight.
Further, since it has high elasticity, it is suitable as a material forming the soft portion 3. As the cell structure, either an open cell structure or a closed cell structure can be molded. However, since the physical properties such as elasticity and heat insulation are different, the desired physical properties may be selected with priority.

Further, since the hard portion 2 and the soft portion 3 are formed of different members, the outer appearance of the toilet seat 1 is made into two colors by molding with different color tones, and a colorful image is created in the toilet. It is possible to give Good luck,
