[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to toilets and similar sanitary fixtures, and more particularly to toilets and similar sanitary fixtures which suppress the solid-borne noise of noise generated during and after use of toilets and other appliances.

[0002]

2. Description of the Related Art Conventionally, in order to reduce noise such as noise generated during use of a sanitary fixture, for example, a toilet bowl and washing noise after use, a space between a bottom surface of the toilet bowl and a top floor of a building where the toilet bowl is installed. In some cases, an elastic plate such as a rubber sheet is interposed to make it difficult to transmit the vibration of the toilet to the floor. (Real opening 64-5984
No.)

[0003]

[Problems to be Solved by the Invention] However, since the conventional one is such that an elastic plate is sandwiched between a toilet and a floor or wall of a building at a construction site, the construction is troublesome, and the rubber sheet or the like is used. The elastic body is, for example, in the case of a floor fixed toilet,
It is necessary to lay on the floor according to the bottom shape of the toilet, but since the bottom shape of the toilet is completely different depending on the manufacturer, type, etc., various types of rubber sheets are prepared to match the elastic body and the bottom shape of the toilet in advance It is necessary to prepare a rubber sheet according to the bottom shape of the toilet in advance and bring it to the site,
Matching is not always possible when relatively large dimensional deviations occur due to toilet tolerances in pottery manufacturing technology. It is conceivable to cut out the rubber sheet according to the bottom shape of the toilet when constructing the toilet, but the work is enormous. Further, as described above, it is necessary to prepare various types of rubber sheets in order to correspond to various toilets, so that the cost increases. The present invention has been made in view of the above-mentioned problems of the prior art, and the object thereof is to sufficiently suppress the solid-borne noise of noise generated during and after use, and has excellent workability. Toilet and similar sanitary equipment.

[0004]

In order to achieve the above object, in the toilet and sanitary equipment of the present invention, an elastic body is integrally attached to a grounding surface of a main body of the appliance with respect to a building floor or a wall. In a toilet and similar sanitary fittings, the elastic body is formed of a rubber or thermoplastic elastomer into a belt-like shape that bends in accordance with the shape of an end face of an annular fixed edge of the body of the appliance, and is laid up at an appropriate position in a width direction of an upper surface thereof. Part is provided, the built-up portion is locked to the inner edge of the fixed edge of the instrument body, and is fixed to the end surface of the annular fixed edge portion by an adhesive means over the entire circumference thereof , and the elastic body is The width dimension from the outer peripheral edge to the build-up portion is made smaller than the width dimension of the annular fixed edge end face of the instrument body . Further, in the toilet and similar sanitary equipment of the present invention, in a toilet and similar sanitary equipment having an elastic body integrally attached to a grounding surface of the appliance main body with respect to the building floor or wall, the elastic body is connected to the appliance main body. It is also characterized in that the melted elastic material applied to the end face of the annular fixed edge is hardened. It is desirable to attach a slippery sheet material to the bottom surface of the elastic body or apply a coating material having an excellent slip property.

[0005]

In the toilet constructed as described above and the sanitary equipment similar thereto, for example, a toilet, a special work process for vibration isolation is not required at the construction site, and the conventional solid-borne noise of noise is suppressed. Just like installing a common toilet without considering the toilet, simply installing the toilet achieves the vibration isolation support of the toilet, and the noise generated during use of the toilet and the noise such as washing noise after use are greatly reduced To be reduced.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a floor-standing toilet A as a sanitary equipment. The structure and form of the appliance main body a are the same as those of a conventionally known general floor-standing toilet, and the bottom shape of the appliance main body a is a manufacturer. Although the shape is completely different for each type, the fixed edge 1 has a width of about 10 mm and has an annular structure following the outer periphery of the bottom for the sake of pottery manufacture. The inside of this annular fixed edge 1 is concave. Has become.

In the present invention, in order to reduce noise such as noise generated during use of the toilet A and washing noise after use in the toilet A, as shown in FIG.
The elastic body 2 for suppressing the propagation of toilet bowl vibration to the floor is integrally provided on the ground plane 11 to the building floor.

The elastic body 2 is made of rubber, thermoplastic elastomer, or the like, and has a hardness of 40 degrees and a thickness of 5 mm. In addition, the elastic body 2 is placed on the floor along the lower surface of the annular fixed edge 1 of the toilet so that the elastic body 2 is sandwiched only in a portion where the appliance body a and the floor abut on the floor when the toilet A is installed on the floor. The portion is provided in an annular shape.

The reason why the elastic body 2 is formed to have a thickness of 5 mm and a hardness of 40 degrees as described above, and to be formed in an annular shape along the lower surface of the annular fixed edge 1 of the appliance body a, that is, the ground surface 11 to the floor, is as follows. For reasons. That is, the results of actual measurement of noise due to differences in the thickness, hardness, shape, building structure, and slab thickness of the elastic body 2 are shown in Table 1. In this measurement, the noise measurement is a value in the lower floor room, and the target sound is a simulated urine sound assuming a male urine act sound. In Table 1, the shape of the elastic body 2 refers to the shape covering the entire bottom surface of the appliance body a of the toilet A, the shape partially covering the bottom surface of the appliance body a of the toilet A at a plurality of locations, and the annular fixing of the toilet A. It has an annular shape along the lower surface of the edge 1.

[0010]

[Table 1]

As is clear from the results shown in Table 1, for any building structure and slab thickness, a sufficient effect can be obtained if the elastic body has a thickness of 5 mm and a hardness of 40 degrees. The shape of the elastic body also greatly affects the effect, and the most effective shape is an annular shape along the lower surface of the annular fixed edge of the toilet. The sufficient effect here is a level at which the urination sound cannot be heard in the downstairs room, and specifically, within "background noise +3 dB", that is, the urination sound is measured in the downstairs room, and the sound pressure level is measured. , Measured sound pressure level when urination is stopped +
This is the case when it is within 3 dB.

In the illustrated example of the present invention, the toilet A
The elastic body 2 integrally attached to the ground plane 11 on the floor of the appliance main body a of the instrument body a in order to maximize the effect of suppressing the solid-borne sound of noise,
It has a thickness of 5 mm and a hardness of 40 degrees, and is formed and attached in an annular shape along the lower surface of the annular fixed edge 1.

On the other hand, porcelain sanitary fixtures such as the toilet A are likely to have dimensional errors due to problems in the porcelain manufacturing technology.
In the case of a floor-standing toilet, the gap between the appliance body a and the floor surface is 2.26 mm on average, and 92.5% is within 3 mm. Needless to say, this gap is desirably as small as possible, and the gap is controlled to 1.5 mm or less by polishing the lower surface of the annular fixed edge 1 of the instrument body a. Accordingly, the actual average polishing amount of the lower surface of the annular fixed edge 1 of the instrument body a is 0.76 mm,
In this polishing step, polishing within 1.5 mm accounts for 92.5%.

On the other hand, the displacement of the elastic body 2 having a thickness of 5 mm and a hardness of 40 degrees due to the fixing of the toilet (assuming the fixing bolt tightening torque at the time of fixing the toilet as 294 Ncm) is about 2.0 mm in part. 92.5% or more of the polishing step for polishing the lower surface of the annular fixed edge 1 of the instrument body a, that is, almost all polishing steps can be omitted.

The elastic body 2 is formed in a band shape and is bent in an annular shape in accordance with the shape of the lower surface of the annular fixed edge 1 of the instrument main body a. Are fixed by an adhesive means 3 such as a double-sided adhesive tape or an adhesive, and an overlaid portion 21 is provided at an appropriate position in the width direction of the upper surface thereof, and the overlaid portion 21 is fixed to the apparatus main body a. Locked to the inner edge of the edge 1.

The built-up portion 21 of the elastic body 2 is engaged with the inner edge of the fixed edge 1 of the instrument body a, thereby bending the elastic body 2 so as to follow the shape of the ground plane 11 of the instrument body a. Thus, the elastic member 2 can perform a positioning function when the elastic body 2 is bonded to the grounding surface 11 of the appliance body a.

As shown in FIG.
May be provided intermittently in the longitudinal direction or may be provided continuously as shown in FIG. 6, but in any case, the width dimension from the outer peripheral edge of the elastic body 2 to the build-up portion 21 is determined by the tool. It is formed slightly smaller than the bottom width of the fixed edge 1 of the main body a. If the width from the outer peripheral edge of the elastic body 2 to the overlay 21 is slightly smaller than the bottom width of the fixed edge 1 of the appliance body a, the elastic body 2 is pressed by the urging force when the toilet A is fixed. Even if it is compressed and its width is widened, it can be prevented that it protrudes from the outer periphery of the fixed edge 1 of the device main body a and impairs the appearance.

As shown in FIG. 4, the elastic body 2 is provided with a number of cuts 22 extending from the inner edge to the outer edge, so that the elastic body 2 can be mounted in the width direction when it is mounted on the bottom surface of the fixed edge 1 of the instrument body a. Can be freely bent, so that it is easy to match the shape of the bottom surface of the fixed edge portion 1,
It is desirable that the notch 22 extends from the overlay 21 to the outer peripheral side.

It is to be noted that this elastic body may have no cutout 22 as shown in FIG. 6 but may be set in the apparatus main body a. Since there is no need for molding, the cost is reduced. Further, a sheet material 4 with good slip is provided on the bottom surface of the elastic body 2
There either attached, with a coating material <br/> excellent in slipping property, for example, silicon or graphite, is coated such as Teflon is applied.

FIG. 7 shows another embodiment of the state of formation of the elastic body 2. As described above, the elastic body 2 integrally adheres the molded article to the ground plane 11 of the instrument body a via the adhesive means 3 as described above. Unlike the fixing device, a melted elastic material 2 'such as a melted rubber is applied on the grounding surface 11 so as to have a uniform thickness of 5 mm, and is dried to be integrally provided on the grounding surface 11. In this case, there is no repulsive force of the elastic body 2, so that the built-up portion 21 is not required for the elastic body 2. Thus, the toilet A is installed on the floor in the same manner as a normal toilet apparatus main body a 'which is not provided with the elastic body 2 and does not support vibration isolation. Is different from the toilet A only in that the elastic body 2 is not provided, and in the case where the apparatus main body a 'having the same other shape and structure as the conventional one exists, the elastic body 2 is simply integrated with the ground plane 11 thereof. If the device main body a ′ equipped with the elastic body 2 only has a height h ″ of the entire toilet A higher than the height h ′ of the existing device main body a ′ as shown in FIG. The height of the elastic body 2 is also increased by 2h, and the height position 5 of the drain port 5 of the toilet A in the installed state.
The height h ”is also higher than the height of the elastic body 2 by 2h, and the connection with the drainage pipe 6 may be out of order, and connection may not be possible, or even if the connection is forcibly performed, water may leak from the drainage connection portion. Therefore, in this embodiment, as shown in Fig. 8 (c), the height h of the appliance body a is formed to be smaller than the height dimension h 'of the existing appliance body a' by the thickness of the elastic body 2 by 2h. do it,
In the installation state, the height is the same as the height h 'of the existing appliance body a'.

In this way, the height 5h of the drain port 5 is 5h 'in the case of the existing appliance body a' in the installed state, although the elastic body 2 is provided integrally with the appliance body a of the toilet A. Therefore, it is possible to eliminate the fluctuation of the connection dimension of the drainage connection part, and to eliminate the risk of water leakage from the drainage connection part even when replacing the existing appliance body a ′.

When the toilet A is installed and constructed, when the toilet A is a wall-drained toilet, the appliance main body a is slid onto the floor surface to join the toilet drain port and the drainage pipe.
By the sheet material 4 or the coating on the bottom surface of the elastic body 2, the sliding of the appliance body a with respect to the floor is good and the construction can be performed easily.

Although the present invention has been described with reference to the case where the present invention is applied to a floor-standing toilet, the present invention can be applied not only to wall-mounted toilets but also to other sanitary equipment similar to toilets. It is possible without changing the gist. When the present invention is applied to a wall-hung toilet, the place where the elastic body 2 is integrally provided is the grounding surface 11 of the appliance body a to the building wall, and the fixed edge portion is annularly formed on the back of the appliance body a. Since the elastic body 2 is formed, the shape of the elastic body 2 also follows the shape of the rear end face of the annular fixed edge.

Further, when the present invention is applied to such a wall-hung toilet, it differs from the toilet A of the present invention in which the elastic body 2 is integrally provided only in that the elastic body 2 is not provided. In the case where there is an existing appliance body a 'having the same shape and structure, if the elastic body 2 is simply provided integrally with the ground plane 11, the appliance body a' equipped with the elastic body 2 is shown in FIG. (B), the front-rear length dimension d ″ of the entire toilet A is longer than the front-rear length dimension d ′ of the existing appliance body a ′ by the thickness 2h of the elastic body 2, and in the installed state, The water supply port 7 of A, that is, the above-mentioned dimension 7d ″ of the mounting position of the water supply fitting is also located forward by an amount equivalent to the thickness of the elastic body 2 for 2h, and the connection with the water supply pipe 8 may be out of order and connection may not be possible. There is.

Therefore, in such a case, FIG.
As shown in the figure, the front-to-rear length dimension d of the instrument body a is formed to be smaller than the length d 'of the existing instrument body a' by the thickness of the elastic body 2 corresponding to 2h, and the existing instrument body a 'in the installed state. So that they have the same length d '.

Thus, despite the fact that the elastic body 2 is provided integrally with the appliance main body a of the toilet A, the front dimension 7d of the water supply port 7 in the installed state is the same as the existing appliance main body a 'front dimension 7d'. In the same manner, it is possible to eliminate the disorder of the connection of the water supply connection part, to make a good connection with the water supply pipe even in the case of replacement with the existing appliance body a ′, and to eliminate the risk of water leakage from the water supply connection part.

As apparent from Table 1 above, depending on the structure of the building and the thickness of the slab, an elastic body having a thickness of 2 mm and a hardness of 70 degrees has the same effect as an elastic body having a thickness of 5 mm and a hardness of 40 degrees. Depending on the structure of the building and the thickness of the slab, the instrument body a may be integrally provided with the elastic body 2 having a thickness of 2 mm and a hardness of 70 degrees on the ground contact surface 11 with the floor or wall of the building. It is also possible.

[0028]

[Effect] Since the present invention is configured as described above, the following effects can be obtained. (1). In toilets and similar sanitary fixtures, an elastic body is integrally attached to the ground surface of the fixture body against the building floor or wall, so various types of anti-vibration sheets molded in advance to the fixtures are prepared, and during construction, It is not necessary to cut off the anti-vibration sheet according to the shape of the grounding surface of the equipment. Of course, at the construction site, special anti-vibration sheets such as inserting the anti-vibration sheet between the equipment and the floor or wall on which it is installed are bothersome. Just as a general toilet installation that does not require a work process and does not take into account conventional solid-borne noise suppression, simply installing the toilet achieves the anti-vibration support of the toilet, allowing it to be used while the toilet is in use. Noise such as generated noise and cleaning noise after use can be significantly reduced. Therefore, the workability is greatly improved and the cost is reduced. (2). The elastic body is formed in the shape of a band, bent according to the shape of the annular fixed edge of the instrument body, and is fixed to the annular fixed edge of the instrument body by adhesive bonding over the entire circumference. Because it has an annular shape along the edge end surface, the noise prevention effect is higher than when the entire surface facing the floor or wall of the appliance body is covered with a vibration isolating sheet or partially covers multiple places, Since only a small amount of elastic material is required, the cost can be reduced. (3). The elastic body has a built-up portion at an appropriate position in the width direction of the upper surface, and the built-up portion is locked to the inner edge of the fixed edge of the appliance main body, so that the elastic body has a shape of a grounding surface portion of the appliance main body. The repulsive force due to the bending in accordance with the shape is suppressed, and the positioning when the elastic body is bonded to the grounding surface of the instrument body is easy, and the manufacturing and assembling properties are good. (4). Since the width dimension from the outer peripheral edge of the elastic body to the build-up portion is smaller than the width dimension of the annular fixed edge end face of the appliance body,
Even when the elastic body is compressed by fastening to the mounting surface of the appliance main body when fixing the toilet and the width is expanded, the elastic body protrudes from the outer periphery of the fixing edge of the appliance main body, and the disadvantage that the appearance is impaired. Absent. (5). Since the elastic body is provided integrally with the instrument body by curing the melted elastic material applied to the end face of the annular fixed edge of the instrument body, a built-up portion such as a case where the elastic body formed in a band shape is adhered to the instrument body. Does not require the equivalent of
The elastic material can be reduced by that much, and the cost is reduced. (6). Either a slippery sheet material is stuck on the bottom surface of the elastic body, or a coating material with excellent slip properties is applied, so the backside of the elastic body is slippery, and the instrument body is attached to the installation surface when installing the equipment. In the case where the position may be shifted by sliding, it is not only possible to easily slide the instrument body, but also there is no possibility of damaging the mounting surface by sliding the instrument, so that the workability is good.
