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 composed of two members, a hard part and a soft part, to improve the usability when seated, and a design with two colors. It is related to the toilet seat that has been improved.

[0002]

2. Description of the Related Art Conventionally, a 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 cool 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 Nos. 56-111892 and 56-111893 disclose a technique for molding a toilet seat with urethane foam. .. In addition, the actual exploitation 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 foamed 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 because of 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 wasn't 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 in which the cushion body is detachable, which is disclosed in Japanese Patent No. 53091, 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, there is no stereoscopic effect and the image becomes 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 configuration, but also leaves it out. 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. An object of the present invention is to provide a toilet seat that can improve the designability by using two-color external parts with a member and can stably hold the skin contact part on the base part during use.

[0010]

The toilet seat according to the present invention comprises:
The inner peripheral side of the toilet seat and the outer peripheral side of the base portion of the hard portion formed as a part of the design portion, while forming the mounting hole and the uneven surface, the soft portion forming the skin contact portion of the toilet seat, It is detachably attached to the hard portion by engaging with the concave-convex surface of the hard portion via a locking projection that is elastically locked in the mounting hole of the hard 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. Moreover, since the skin contact portion is formed of the soft portion, the user does not feel uncomfortable, numb, or pain, and the soft portion does not have a cold sensation during the winter season. Furthermore, by elastically inserting and locking the locking projection provided on the soft part into the mounting hole of the hard part, the soft part can be easily mounted, and the impact at the time of opening and closing, rough handling It is possible to prevent it from coming off due to such reasons as well as to surely prevent the soft portion from being displaced when it is seated by engaging with the uneven surface of the hard portion. On the other hand, by lifting the soft portion, the locking projection is elastically deformed and pulled out from the mounting hole of the hard portion, and the soft portion can be removed. 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 that 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. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a perspective view of a toilet bowl to which a toilet seat according to an embodiment of the present invention is attached, FIG. 2 is a perspective view showing a state in which a soft portion is removed from the toilet seat of an embodiment of the present invention, and FIG. A-
It is sectional drawing by the A cutting line.

In the figure, a toilet seat 1 of a stool-type toilet is composed of a hard portion 2 and a soft portion 3. The toilet seat 1 is pivoted about one end of the rigid portion 2 and is attached to an opening of a toilet body 4 so as to be freely opened and closed. ing.

The hard portion 2 of the toilet seat 1 is formed in an annular shape in a portion corresponding to the bottom surface and the outer peripheral portion of the toilet seat 1, as shown in FIG.
As shown in FIG. 2, a horizontal surface 2 that reaches almost the entire circumference and comes into contact with the upper surface portion of the toilet body 4 via a cushion material described later.
a, a vertical surface 2b standing vertically from the outer peripheral side end portion of the horizontal surface 2a, and a design surface 2 forming an outer peripheral side design portion by hanging downward in an arc shape from the upper end portion of the vertical surface 2b to an outer oblique downward direction.
and c. The horizontal surface 2a and the vertical surface 2b of the hard portion 2 constitute a base portion of the toilet seat 1.

Further, the horizontal surface 2a is provided with a plurality of mounting holes 2d at appropriate intervals in the circumferential direction.

Further, on the horizontal surface 2a, a rib 2e for preventing the positional deviation is formed almost all around and parallel to the peripheral edge.

The hard portion 2 is integrally formed by injection molding or the like using a synthetic resin material such as PP, ABS or nylon.

On the other hand, on the upper part of the hard portion 2 of the toilet seat 1,
The soft portion 3 is placed, and the bottom surface 3a and the outer peripheral surface 3b of the soft portion 3 are in contact with the horizontal surface 2a and the vertical surface 2b of the hard portion 2, respectively. Further, a taper surface is formed on the upper surface of the soft portion 3 so as to incline downward from the outer peripheral side toward the inner peripheral side, and a skin contact surface 3c with which the buttocks and legs of the human body come into contact is formed almost all around. Has been done. The plane shape of the skin contact surface 3c forming the taper surface is formed in 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 by 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, the bottom surface 3a of the soft portion 3 is integrally provided with an umbrella-shaped locking projection 3d projecting downward at a position corresponding to the mounting hole 2d of the hard portion 2. The locking protrusion 3d has a pillar having substantially the same height as the plate thickness of the horizontal surface 2a of the hard portion 2, and an external dimension of the bottom portion formed on the upper portion (lower portion in FIG. 3) of the mounting hole of the hard portion 2. It is composed of a frustoconical locking part having a larger inner diameter than 2d. That is,
When the locking projection 3d of the soft portion 3 is placed in the mounting hole 2d of the hard portion 2 and pressed, the outer peripheral portion is elastically deformed and the mounting hole 2d.
It can be inserted into the inside, and after the insertion, the locking protrusion 3
The outer peripheral portion of the bottom surface of d contacts and engages with the horizontal surface 2a of the hard portion 2.

Further, the bottom surface 3a of the soft portion 3 is formed with an engaging groove 3e which is engaged with the rib 2e of the hard portion 2 almost all around and parallel to the peripheral edge.

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 locking protrusion 3d provided on the bottom surface 3a of the soft portion 3 is
It faces the mounting hole 2d formed in the horizontal surface 2a of the hard portion 2. Therefore, when the soft portion 3 is pressed from above, the outer peripheral portion of the locking projection 3d is inserted into the mounting hole 2d of the hard portion 2 while being compressed by the elastic deformation of the soft material, and the locking projection 3d is locked. When the portion penetrates, the outer periphery of the portion is elastically restored and locked in the mounting hole 2d. As a result, the horizontal surface 2a of the hard portion 2 is held between the main body portion of the soft portion 3 and the locking projection 3d, the hard portion 2 and the soft portion 3 are integrated, and 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, the horizontal movement is restricted, and the soft portion 3
Since the skin contact surface 3c is a taper surface 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
Since b is strongly pressed, it does not come off from the hard portion 2 during use.

Further, the soft portion 3 and the hard portion 2 are firmly joined by the plurality of locking projections 3d provided at predetermined intervals in the circumferential direction of the soft portion 3, so that the soft portion 3 is joined.
However, the toilet seat 1 does not come off due to impact when opening or closing the toilet seat 1, or rough handling. In addition, the rib 2 of the hard portion 2
Since e and the engaging groove 3e of the soft portion 3 are engaged with each other, it is possible to prevent horizontal displacement when seated, particularly between the mounting portions of the locking projections 3d of the soft portion 3.

By the way, the locking projection 3d of the soft portion 3 holds the horizontal surface 2a of the hard portion 2 together with the main body of the soft portion 3, and the elasticity of the soft material causes it to engage with the toilet body 4 when the toilet seat 1 is opened and closed. It also acts as a cushioning material that absorbs shocks.

On the other hand, when the soft portion 3 is removed, if the soft portion 3 is lifted, the locking projection 3d of the soft portion 3 is elastically compressed at its outer peripheral portion, and the inner diameter of the mounting hole 2d of the hard portion 2 is larger than the inner diameter. Becomes smaller and is removed, and the soft part 3 can be removed upward.

Next, the operation of the toilet seat of this embodiment will be described.

The hard portion 2 is formed of a hard material made of a synthetic resin material such as PP, ABS, nylon and the like, and moreover the rigidity is improved by the convex sectional shape formed by the vertical surface 2b and the design surface 2c. Thus, it has a required rigidity and maintains a predetermined shape without being deformed by the pressing force when the user sits down.

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 function of the foam, the cold feeling in the winter is eliminated and the foam can be used comfortably.

Various foams 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 by 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 Goodbye,
It is possible to express a sense of the season, and it is possible to decorate a color or a pattern suitable for a user for adults or children.

As described above, the toilet seat of the above embodiment is the toilet seat 1
A mounting hole 2d and a rib 2e serving as an uneven surface are formed on the horizontal surface 2a of the hard portion 2 whose inner peripheral side is formed as the base portion and outer peripheral side is formed as a part of the design portion, and the skin contact portion of the toilet seat 1 is formed. The soft portion 3 is engaged with the rib 2e of the hard portion 2 through the engaging projection 3d that is elastically engaged with the mounting hole 2d of the hard portion 2, thereby engaging the hard portion 2 with the engaging groove 3e. It is detachably attached to. Therefore, according to the above-described embodiment, the rigid portion 2 has a required strength as the toilet seat 1 and can sufficiently withstand the pressing force even when the user sits down.

Further, the soft portion 3 has the locking projection 3d and the hard portion 2
Since the rib 2e and the engagement groove 3e engage with each other by being inserted into the attachment hole 2d of the above, and the rib 2e and the engagement groove 3e engage with each other, the soft portion 3 can be stably and inexpensively provided with a simple structure. It can be held, prevents it from coming off due to shock when opening and closing, rough use, etc., and prevents the shift when sitting, giving the user a sense of stability, and by raising the soft part 3 when necessary. The stop projection 3d is unlocked and can be easily removed.
Therefore, depending on the body shape of the user, for example, for a dwarf, an adult, an obese person, or for a special purpose, it can be appropriately exchanged for a disabled person, and can be used at any time. It can be replaced with a feeling one, and can be easily replaced when it becomes dirty or damaged. In addition, since the soft portion 3 forming the skin contact portion that is easily soiled can be removed and cleaned, the work becomes easy and sanitary.

Furthermore, since the locking projection 3d is formed of the same soft material as the main body of the soft portion 3, it also functions as a cushioning material having a high elasticity for cushioning the impact when the toilet seat 1 is opened and closed. The cost is reduced as compared with the case where a cushion material is separately provided.

Since the skin contact portion is formed by the soft portion 3 made of a soft material, the user feels uncomfortable, numb,
It does not cause pain, and does not give the user a cold sensation due to the heat insulating function of the soft portion 3 in winter.

In addition, since the toilet seat 1 is made up of two members, the hard portion 2 which constitutes a part of the base portion and the design portion, and the soft portion 3 which is the skin contact portion and also serves as the design portion, they are different from each other. By molding with a different color tone, you can enjoy high-quality coloring and improve the design. Moreover, since this two-colorization can be achieved only by adding a colorant to the molding material, it is possible to easily and inexpensively provide a high-class design without using any special means such as printing. Furthermore, by appropriately changing the combination of designs of the hard portion 2 and the soft portion 3, the degree of freedom in design design can be increased, and diversifying needs can be met.

By the way, the locking portion of the locking projection 3d provided on the soft portion 3 of the above-mentioned embodiment has a truncated cone shape.
When carrying out the present invention, the present invention is not limited to this, and any shape that can be locked in the mounting hole 2d of the hard portion 2 can be set.

Further, the rib 2e and the engaging groove 3e for preventing the positional deviation of the above-mentioned embodiment are formed almost all around and parallel to the peripheral edge, but when the present invention is carried out, it is limited to this. However, it may be partially provided, or may be provided in the direction perpendicular to the peripheral edge or the like. Furthermore, the hard part 2
The concave-convex surface for preventing the positional deviation formed in (1) is not limited to the rib 2e, and can be formed in various shapes such as a plurality of columnar projections.

In addition, in the embodiment of the present invention, in addition to the locking structure by the mounting hole 2d of the hard part 2 and the locking projection 3d of the soft part 3, a double-sided tape, a surface fastener, etc. can be easily attached and detached. It does not prevent the provision of such known means.

Further, although the hard portion 2 of the above embodiment has a shape in which the vertical surface 2b is provided upright on the outer peripheral side, the present invention is not limited to this, and the inner peripheral side is not limited to this. The vertical surface 2b may be provided upright, or may be provided on both sides. However, in consideration of the directionality of the pressing force applied when the user is seated, the contact condition when the user is seated, etc., FIG.
The shape shown in is preferable.

Further, in the soft portion 3 of the above-mentioned embodiment, the skin contact surface 3c is a taper surface which hangs from the outer peripheral side toward the inner peripheral side. However, when the present invention is carried out, it is limited to this. The shape is not limited to this, and may be any shape that provides a comfortable feeling when seated. The soft part 3 may have a hollow part inside. Thereby, the elasticity of the soft part 3 can be further enhanced.

In addition, the hard portion 2 of the above embodiment is made of PP,
It is made of synthetic resin material such as ABS and nylon.
