DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure for a toilet member such as a toilet seat.

[0002]

2. Description of the Related Art Conventionally, in the toilet seat of a toilet bowl, water has entered the interior of the toilet seat by welding the joint surface between the front and back of the seat by vibration welding or by coating the joint surface. It does not have a structure. However, the conventional joining structure requires a welding machine and equipment for performing a coating process, and has a problem that the assembly productivity is low.In addition, since it is welded, it cannot be disassembled. There is a problem that it is difficult to remove and separate each material, and it cannot be recycled.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and does not require a welding machine or a coating facility, and does not require a coating process.
The object of the present invention is to provide a joint structure of a toilet bowl member that has good assembly productivity and can be easily disassembled.
The first gist is that in a joint structure of a toilet bowl member in which a joining surface of a front member and a back member is brought into contact with each other and joined, a joining surface of the front member or the back member or both joining surfaces are made of a soft material. It is a resin. A second gist is that the soft resin is fixedly integrated with the front member or the back member or both by two-color molding.

[0004]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective configuration diagram of a seat back portion 1 constituting a back side member of a toilet seat arranged on the upper surface of a toilet, and FIG.
FIG. 3 is a perspective configuration diagram in which a seat surface portion 3 constituting a front member of the toilet seat is turned upside down. In the seat back portion 1 of FIG. 1, an outer peripheral joint piece 1a is integrally formed on the outer periphery so as to rise integrally therewith, and an inner peripheral joint piece 1b is also integrally formed on the outer periphery of the toilet seat hole H in the central portion. The inner peripheral joint piece 1b and the outer peripheral joint piece 1a
In between, four boss portions 1c are formed upright, and claw pieces 1d, 1d, 1d, 1d are erected at predetermined intervals inside the outer peripheral joining piece 1a and outside the inner peripheral joining piece 1b. It has become.

In this embodiment, as shown in an enlarged perspective view of FIG. 3, flexible soft resins 2a and 2b are integrated on the inner side of the outer peripheral joint piece 1a and the outer side of the inner peripheral joint piece 1b. Has become. That is, the seat back 1 and the seat front 3 are P
The soft resin 2a, 2b
Is made of, for example, an elastomer resin, and is integrated by two-color molding at the time of manufacturing the seat back portion 1 made of PP resin. Note that the soft resins 2a and 2b protrude above the outer peripheral joint piece 1a and the inner peripheral joint piece 1b, and the upper surface thereof is a joint surface P.

On the other hand, as shown in FIG. 2, the seat surface portion 3 is integrally raised on the outer periphery to form an outer peripheral joint piece 3a, and the upper surface of the outer peripheral joint piece 3a forms a joint surface P. ing. An inner peripheral joint piece 3b is also integrally formed on the outer periphery of the toilet seat hole H in a rising shape, and the upper surface thereof constitutes a joint surface P. Further, four reinforcing projections 3d, 3d, 3d, 3d are integrally formed between the inner peripheral joint piece 3b and the outer peripheral joint piece 3a in a protruding manner.

As shown in the enlarged sectional view of FIG.
On the other hand, when the seat surface portion 3 is joined at the joining surface P, the soft resin 2a comes into contact with the joining surface P of the outer peripheral joining piece 3a of the seat surface portion 3, and since the soft resin 2a is soft, the soft resin 2a It will be joined in a close contact state, even if it does not perform coating treatment, it will have a joint structure that water etc. does not enter inside,
Watertightness can be reliably ensured. Note that the soft resin 2b is joined to the joining surface P of the inner peripheral joining piece 3b of the seat surface portion 3 in a close contact state, and watertightness is ensured.

In this state, the seat back portion 1 and the seat surface portion 3 can be connected and fixed with four screws by passing screws through the boss portions 1c, 1c. In this embodiment, the claw pieces 1d, 1d, 1d, 1
d is engaged with the locking portions 3c, 3c, 3c, 3c of the seat surface portion 3 and assists the connection between the seat back portion 1 and the seat surface portion 3, and bending may occur with only four screws. Therefore, the plurality of claw pieces 1d, 1d are configured to fix both.

Therefore, there is no need for a conventional welding machine or mechanical equipment for performing a coating process, and the seat surface portion 3 can be pressed against the seat back portion 1 to assemble and secure watertightness. Moreover, by removing the four screws, the seat back 1 and the seat front 3 can be easily disassembled, and the heater disposed inside can be removed to easily separate the resin material. , Making it easy to recycle.

In this embodiment, as shown in FIG. 4, a structure is shown in which a soft resin 2a is integrated by two-color molding inside the outer peripheral joining piece 1a. It may be configured to be fixedly integrated with the outside of the joining piece 1a.

Further, as shown in FIG. 5 and FIG. 6, a joining convex portion 1e is formed to protrude upward on the outer periphery of the seat back portion 1,
The softening resin 2 is fixed and integrated with the upper end of the joining protrusion 1e by two-color molding, and the width of the softening resin 2 is set to be smaller than the width of the soft resin 2 on the outer periphery of the one seat portion 3 to form a dent. The joining groove 3e is formed, and at the time of assembling, as shown in FIG. 6, the soft resin 2a is pushed into the joining groove 3e to bring the soft resin 2 into close contact with the joining groove 3e. 1 for 1
Can be assembled so as to ensure the watertightness, and the watertightness can be ensured without performing the coating process, so that the assembling operation can be easily performed. Further, the disassembly can be easily performed later.

Further, as shown in FIG. 7, a soft resin 2 is fixed and integrated by two-color molding in the joint groove 3e on the seat surface portion 3 side. It is also possible to adopt a structure in which the joining convex portion 1e is pressed and joined.
The joining convex portion 1e is pressed into the soft resin 2 so that good watertightness can be secured.

The structure in which the soft resin 2 is fixed and integrated by two-color molding and joined is applicable not only to the toilet seat but also to the toilet seat box 4 as shown in FIG. The soft resin 2 is fixed and integrated into the toilet seat box 4 in which the functional parts of the apparatus are built, for example, inside the outer peripheral joint piece 5a of the back side member 5 by two-color molding. The back side member 5 and the front side member 6 can be assembled with good contact with the joint surface P of the outer peripheral joint piece 6a of the front side member 6 without any need for coating. Thus, the assembling work is easy and the disassembling is easy. Others
Even for a toilet member that needs to secure water tightness by assembling the front side member to the back side member, it is possible to use a soft resin 2 on the bonding surface to form a bonding structure free of water or the like. .

[0014]

According to the present invention, there is provided a joint structure for a toilet member which is joined by bringing the joint surfaces of a front member and a back member into contact with each other.
By using a flexible soft resin for the joint surface of the front member or the back member or both joint surfaces, the front member and the back member can be securely assembled without coating treatment and can be assembled with water tightness. The attachment work is easy, and the equipment of the conventional welding machine is not required, and it can be disassembled and can be recycled well.

Further, since the soft resin is fixed and integrated to the front member or the back member or both by two-color molding, the soft resin is preferably fixed and integrated by two-color molding when manufacturing a toilet member. And the productivity is good.
