[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for providing a base for supporting a leg of a bath tub.

[0002]

2. Description of the Related Art When a bathtub is installed, generally, a bundle of concrete blocks is used for each leg in order to provide a base for a plurality of legs. Then, in order to eliminate the unevenness of the floor surface on which it is placed and obtain an appropriate water gradient in the bathtub, when installing the bathtub at the site, mortar is raised on each slab, and the legs of the tub are The raised mortar on the slab is cured in a crushed state, so that all the legs can be stably placed and supported on the slab.

[0003]

However, when a gantry is provided by the above-described conventional method, it is indispensable to properly apply mortar in order to stably mount and support the legs of the bathtub on the slab. . However, since mortar is usually made by hand kneading on site, it is difficult to maintain its hardness constantly at each site. If the mortar is too soft, it will hang down due to its own weight before the bathtub is installed, and the legs of the bathtub will not be placed. There may be a gap between the bathtubs, and there is a risk that the bathtub may tilt when hot water is poured into the bathtub or when a person enters the bathtub. On the other hand, even if the mortar is too hard, when installing the bathtub, the mortar must not be crushed by the weight of the bathtub alone, and excess mortar must be scraped off. In the case described above,
Since the work of adding the mortar that is insufficient or removing the excess mortar is a work in an extremely narrow space below the bathtub, not only does it require a great deal of labor, but it is difficult to perform a reliable work, and as a result, as a whole However, there is a problem that it is difficult to stably install the bathtub in spite of labor. In view of the above circumstances,
An object of the present invention is to provide a bathtub mount member that enables stable installation of a bathtub with a simple operation.

[0004]

Means for Solving the Problems As a first means taken to solve the above-mentioned problems, a characteristic structure of the member for a bathtub stand of the first invention is to provide a hardening material accommodating space capable of accommodating a curable material. The frame to be formed has an opening for receiving the leg of the bathtub in the hardening material storage space, and a tube for injecting the hardening material into the hardening material storage space is provided. It is in.

[0005] The second aspect of the present invention, which is a measure taken to solve the above-mentioned problem, is a characteristic feature of the bathtub mount member according to the second invention, which is a curable material capable of vertically expanding and contracting and capable of containing a curable material therein. In a sealed container having a housing space, a mounting portion for mounting and supporting the legs of the bathtub and a grounding portion for installation are formed, and a tube material for injecting a hardening material into the hardening material housing space, and And a discharge hole for discharging the residual gas in the hardening material storage space.

[0006]

When the bathtub mounting member of the first invention is used, when installing the bathtub, first, a frame is set on the floor surface, and the legs of the bathtub temporarily suspended and supported at a predetermined height are formed on the frame. When the curable material such as mortar or resin is injected into the hard material accommodating space through the tube while being received in the hard material accommodating space in the frame via the opened opening, the injected curable material is cured. By filling the storage space, the lower end of the bathtub leg can be buried in the hardening material, so that the hardening material hardens, so that the bathtub leg can be securely supported. become. The determination of whether or not the curable material has filled the curable material accommodating space is made by injecting the curable material in a slightly larger amount than the volume of the space, so that the curable material from the opening portion of the frame body is injected. You can easily see the overflow. The curable material is prevented from dripping by the frame, and does not flow backward if the inlet of the tube is closed, so even if the curable material is somewhat soft, the lower end portion of the bathtub is once set to the curable material. Once buried, there is no gap below the bathtub legs.
In addition, since a work mode in which the legs of the bathtub positioned in advance are received and the curable material is later filled into the space into which the legs enter, the legs of the bathtub can be supported at an appropriate height. In addition, since the curable material is injected through the pipe, if the pipe is of the required length according to the conditions at the construction site, it will also be possible to confirm the overflow of the curable material as described above. Coupled with the fact that it can be performed simply by visual recognition, the installation work of the bath tub can be performed without entering the bath tub which is difficult to work at all.

On the other hand, when the bathtub mounting member of the second invention is used, when the bathtub is installed, first, the grounding portion of the sealed container is installed on the floor surface, and the bathtub is temporarily suspended and supported at a predetermined height. When a curable material such as mortar or resin is injected into the hardening material storage space through the through hole, the injected hardening material fills the hardening material storage space while discharging the residual gas from the discharge hole, thereby forming a sealed container. Can be extended in the vertical direction so that the mounting portion can be brought into contact with the lower portion of the leg of the bathtub, so that the curable material is hardened, so that the leg of the bathtub can be securely supported. It is easy to determine whether or not the curable material has filled the curable material storage space by visually checking that the curable material overflows from the discharge hole after the residual gas in the curable material storage space is discharged from the discharge hole. After that, the closed container can be extended by closing the discharge hole and injecting the curable material further, and whether or not the mounting portion has contacted the lower end of the leg of the bathtub is determined at the time of further injection. Can be easily known from the rapid increase in the injection pressure. And since the curable material is prevented from dripping by the sealed container, it does not flow backward if the injection port of the tube is closed,
Even if the curable material is somewhat soft, once the mounting portion of the sealed container abuts the lower ends of the legs of the bathtub, no gap is formed below the bathtub thereafter. In addition, since an operation mode in which the hermetically sealed container filled with the curable material is brought into contact with the leg of the bathtub which is positioned in advance from below, the leg of the bathtub can be supported at an appropriate height. In addition, since the curable material is injected through the pipe, if the pipe is of the required length according to the conditions at the construction site, it will also be possible to confirm the overflow of the curable material as described above. Coupled with the fact that it can be performed simply by visual recognition, the installation work of the bath tub can be performed without entering the bath tub which is difficult to work at all.

[0008]

[Effects of the Invention] Therefore, regardless of whether the member for the bathtub stand of the first invention is used or the member for the bathtub stand of the second invention is used, the structure of the bathtub can be reduced. It is possible to securely support all the legs of the bathtub without the risk of forming a gap below the legs, to avoid a situation in which the bathtub is tilted after installation, and to use any one of the bathtubs. It is also possible to install the bath tub without performing the difficult work of entering the lower part of the tub, and as a whole, it has become possible to provide an excellent member for a bath tub stand that can be reliably executed and has good workability. .

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

First, the member for a bathtub stand of the first invention will be described.

As shown in FIG. 1, the bathtub base member of the first invention is connected to a cylindrical frame 1 and a peripheral wall of the frame 1, and the interior communicates with an internal space 2 of the frame 1. And a vinyl tube 3 which is an example of a tube material. The frame 1 is formed, for example, by cutting a hard vinyl chloride pipe. Then, a pair of openings 1A to be formed in the cut portion, with the frame body 1 installed on the floor surface, one of which is closed by the floor surface, the other is opened upward, The legs B of the bathtub T are connected to the inner space 2 of the frame 1.
It has become accepted. In addition, this frame 1
Can be used in the same manner even if it is turned upside down.

Bathtub T using the above-mentioned bathtub mount member
To describe the installation work, first, the four frame bodies 1 are positioned at the locations where the bathtub T is to be installed, corresponding to the four legs B of the bathtub T. Next, the bath tub T is temporarily fixed at a set height while the legs B of the bath tub T are inserted into the internal space 2 of the frame 1 from the opening 1A above each frame 1. Thereafter, mortar, which is an example of a curable material, is injected into the internal space 2 of the frame 1 via the vinyl tube 3. If the mortar M fills the internal space, that is, the hardening material accommodating space 2, the leg B of the bathtub T located below the opening 1A at the upper part of the frame 1 is buried in the mortar M. Becomes In this state, if the injection port of the vinyl tube 3 is closed and the mortar M is hardened, the leg B of the bathtub T is securely placed on the hardened mortar M and is securely supported. This state is shown in FIG.

The fact that the leg B of the bathtub T is buried in the mortar is confirmed by visually confirming that the injected mortar M overflows from the upper part after filling the hardened material accommodating space 2 of the frame 1. , You can check.

As described above, the legs B of the bathtub T can be reliably mounted and supported on the mortar, and the mortar can be injected from a place remote from the bathtub T via the vinyl tube 3. Work in a narrow space below can be eliminated, and stable support of the bathtub T can be performed with good workability.

The frame 1 is not limited to the above-mentioned vinyl chloride tube, but may be made of any material, may be a square tube, or have a bottom. Is also good. Further, as the pipe material 3, rigid pipes may be used instead of a flexible one such as a vinyl tube, and any material may be used. Curable material M
May be a resin or the like in addition to mortar, and may be an air-hardening material or a material which is cured by ultraviolet irradiation or heating. In the case of an ultraviolet curing type, the frame 1 is made of a transparent material. It is preferable to form the frame 1 from a heat-resistant material in the case of a thermosetting type.

The size of the opening 1A may be such that only one leg B of the bathtub T can be accommodated, or some of the plurality of legs B can be accommodated. Further, a plurality of openings 1A may be formed in one frame 1. In an extreme case, all the legs B may be received in the same hardening material storage space 2.

Next, the member for the bathtub stand of the second invention will be described.

As shown in FIG. 3, the bathtub mount member according to the second invention has a sealed container 4 having flat portions 4A and 4B at the top and bottom and a bellows-shaped peripheral portion, and a peripheral wall of the sealed container 4. And a first vinyl tube 6 which is an example of a tube material which is connected to an inner space 5 of the sealed container 4 and which is connected to an upper end of a peripheral wall of the sealed container 4. Second vinyl tube 7 whose interior communicates with space 5
It is composed of

The work of installing the bathtub T using the bathtub mount member will be described. First, four sealed containers 4 are located at the locations where the bathtub T is to be installed, corresponding to the four legs B of the bathtub T. . Next, the bathtub T is temporarily fixed to the set height,
Mortar M, which is an example of a curable material, is injected into the internal space 5 of the sealed container 4 through the vinyl tube 6 described above.
The mortar is placed in its internal space, that is,
As the air is filled into the inside, the air, which is the residual gas in the hardening material accommodating space 5, is discharged from the discharge hole 7a through the second vinyl tube 7. And mortar M
Is filled in the hardening material accommodating space 5, the mortar M overflows from the second vinyl tube 7. At that time, the discharge hole 7a of the second vinyl tube 7 is closed and the first vinyl tube 7 is further closed. If the injection of the mortar M through the vinyl tube 6 is continued, the sealed container 4 extends upward so that the bellows-like peripheral portion of the sealed container 4 is expanded, and the sealed container 4 is expanded.
The flat portion 4A on the upper surface contacts the leg B of the bathtub T from below. In this state, the injection port of the first vinyl tube 6 is also closed, and if the mortar M is hardened, the bathtub T
The leg B is securely placed on the hardened mortar M via the flat portion on the upper surface of the sealed container 4, that is, the mounting portion 4A, and is firmly supported. This state is shown in FIG.

The fact that the mounting portion 4A of the sealed container 4 has reliably contacted the leg B of the bathtub T means that the injection pressure suddenly increases when the mortar is injected to extend the sealed container 4,
Alternatively, it can be confirmed that injection is no longer possible. Further, if the mortar is continuously pressed from this state, fine adjustment of the supporting height of the leg B can be performed.

As described above, the leg B of the bathtub T can be reliably placed and supported on the mortar M, and the mortar can be injected from a place away from the bathtub T via the first vinyl tube 6. Therefore, work in a narrow space below the bathtub T can be eliminated, and stable support of the bathtub T can be performed with good workability.

The sealed container 4 is not limited to the shape and form of the above-described embodiment. For example, the outer cylinder and the inner cylinder may be slidably tightly fitted, and may be configured to be vertically expandable and contractible. In addition, the material is not important. Further, as the pipe member 6, rigid pipes may be used instead of the flexible one such as the above-mentioned first vinyl tube, and any material may be used. further,
Regarding the discharge hole 7a formed in the second vinyl tube 7 in the above-described embodiment, the force required to expand and contract the sealed container 4 is considerably smaller than the flow resistance of the curable material at the discharge hole 7a. If there is, it may always be kept open, in which case the discharge hole 7a may be provided at the upper end of the sealed container 4 itself. The curable material M may be a resin or the like in addition to the mortar, and may be an air-hardening material or a material that is cured by ultraviolet irradiation or heating. Is preferably formed from a transparent material, and in the case of a thermosetting type, the sealed container 4 is preferably formed from a heat-resistant material.

The size of the mounting portion 4A may be such that only one leg B of the bathtub T is mounted or some of the plurality of legs B are mounted together. . In extreme cases, all the legs B may be mounted at once.
