Description

The present invention relates to a pedestal used for obtaining a predetermined height and level in a bathtub installed by a method of embedding in a pit.

If the bathtub is classified according to the installation method, it can be divided into one that is built integrally with the building frame and one that is built separately from the building frame and installed in the building. There are two types of bathtubs that are built separately from the building frame: a “stationary” type that is simply installed on a flat floor, and a “semi-embedded” type that embeds a part of the bathtub in a recess called a so-called pit. (FIG. 7) and “embedded type” (FIG. 6) in which the bathtub is entirely embedded in the pit. The present invention is directed to a bathtub installed in a “semi-embedded” or “embedded” method.

There are two problems in embedding the bathtub in the pit: installing the bathtub at a height that is easy to enter when the user enters, and installing the bathtub horizontally. The height of the bathtub is determined by the depth of the pit and the degree of embedding the bathtub. As for the horizontal installation of the bathtub, the floor on which the bathtub is installed usually has a water gradient due to concrete finishing by hand, and therefore it has always been necessary to devise. In the prior art, protrusion-like legs 41 are attached to the four corners of the bottom of the bathtub 40 to adjust the height of the legs 41 (FIGS. 8 and 9), or two rail-like legs attached to the bottom of the bathtub 40. Horizontal was obtained by laying the auxiliary plate 45 between 43 and the floor 5 (FIGS. 10 and 11).

However, it is not easy to adjust the height by the conventional method. The space between the pit and the bathtub is minimized in order to reduce space, and after the bathtub is installed in the pit, the installation worker cannot put his hands on the bottom of the bathtub. Therefore, the horizontal level was finally obtained by repeating the work of installing the bathtub once in the pit, checking the level of the level, pulling out the bathtub from the pit, adjusting the leg height, and returning it to the pit again. . Since the bathtub is heavy, its work is very hard work and wastes time and labor.

Also, the bathtub usually weighs more than about 500 kilograms when the user bathes in a full bath. Therefore, it is necessary to firmly support the bottom of the bathtub, but the conventional method of supporting with the protruding legs provided at the four corners of the bottom and the two rail-shaped legs on the bottom is not sufficient to support firmly. there were. That is, as a result of long-term use, the bathtub was deformed, the bathtub was deformed, and the sealing provided between the bathroom wall and the washing place was peeled off to cause water leakage. Therefore, the area where the bathtub and the installation floor are in contact with each other has to be increased, and the weight of the bathtub must be dispersed and supported. However, the part where the bathtub and the installation floor are in contact with each other needs to ensure that the weight of the bathtub is evenly distributed between the parts. I couldn't increase the part.

As a method for installing a unit bath or floor pan, a method of providing a support frame separate from the unit bath or floor pan is known (Patent Document 1, Patent Document 2, Patent Document 3). However, in the installation of a bathtub, there is a characteristic that unit baths and floor pans do not have that they need to be sealed in the pit after being embedded in the pit. That is, in the bathtub, as shown in FIGS. 6 and 7, the upper edge 2 of the bathtub is in close contact with the wall of the pit 3, and one side wall of the bathtub is in close contact with the bath washing area extending from one side wall of the pit. Thus, after the bathtub is embedded in the pit and embedded, it is necessary to seal each of the close contact portions with a sealing 37 to obtain a sealing property. For this reason, it is required that the gap between the pit and the side wall of the bathtub is extremely small, and that the distance between the pit and the bathtub is accurately maintained when embedding. Due to such unique features of the bathtub installation method, the installation method of the unit bath and the floor pan could not be directly applied to the bathtub installation method.

There is also a conventional technology for a bathtub base that can be adjusted in height (Patent Document 4). However, it is not assumed to be embedded in a pit, and this conventional technique cannot be applied as it is to a bathtub embedded in a pit.
Japanese Patent No. 3541536 JP 2001-107411 A 5-32597 JP-A-10-33403

Let it be a subject to solve the problem of the above-mentioned conventional bathtub installation method. That is, in a bathtub of a method of installing a bathtub by an embedded or semi-embedded method, a mechanism that can easily obtain a predetermined height and level of the bathtub, a mechanism that can firmly support the bottom of the bathtub, and the result The purpose is to provide a mechanism that can withstand long-term use.

In the bathtub installed in the pit, it is a stand separate from the bathtub placed between the pit floor and the bathtub, and is a rod-like leg screwed to the stand, and has a screw hole extending in the axial direction inside. When the pedestal is placed in the pit, one end of the leg directed downward is in contact with the pit floor, and the other end of the leg directed upward is arranged so that the screw hole is opened, The problem is solved by a gantry equipped with a vertical position adjusting means that changes the distance between the gantry and the one end of the leg by operating a screw hole and a wrench to determine the vertical position of the gantry.

After installing a pit and a stand, and adjusting the height of the stand and obtaining the level, the bathtub is placed on the stand. Thereby, the operation | work which takes in / out a heavy bathtub from a pit becomes unnecessary.

The rod-like leg screwed to the gantry is, for example, a bolt. After mounting the mount on the pit, it can be operated with a wrench from the screw hole that opens at the end of the screw section by attaching it to the mount so that the head of the bolt faces downward and the tip of the screw section faces upward It becomes possible. With such a structure, the height of the gantry can be adjusted. Adjust the height of each part of the gantry and place the level ruler on the gantry to obtain the level of the gantry.

The leg has a seat part in contact with the pit floor at one end, and the leg is rotatable with respect to the seat part.

The seat portion is, for example, a bolt head. Since the screw part is rotatable with respect to the bolt head, when the screw part of the bolt rotates after the screw part head comes into contact with the floor surface of the pit, the screw part head does not follow the screw part. Does not rotate. Thereby, frictional resistance between the screw head and the pit floor does not occur.

The problem is solved by a gantry comprising four or more vertical position adjusting means. In addition, the frame solves the problem by having a horizontal position fixing means for determining a horizontal position of the frame by an operation performed after the frame is installed in the pit.

The mount is a quadrilateral, and the horizontal position fixing means is by fixing the distance between the mount and the pit wall with bolts provided on each side of the quadrilateral. Resolve. The gantry consists of quadrilateral leg frames. The leg frame may be made of wood, metal or plastic.

The mount is a quadrilateral, and the horizontal position fixing means is based on fixing the distance between the mount and the pit wall with a bolt screwed to each side of the quadrilateral. To solve.

The problem is solved by a frame characterized in that the frame has a reinforcing leg frame. When the gantry has the reinforcing frame, the bottom surface of the bathtub is strongly supported, and the bathtub can withstand long-term use.

With no bathtub in the pit, the height and level of the bathtub can be adjusted easily.

Since the height of the bathtub is easy to adjust, the height can be carefully adjusted, and a high level of accuracy can be obtained.

Since the height can be easily adjusted, the force can be evenly distributed to the portion receiving the weight of the bathtub. As a result, the part which receives the weight of a bathtub can be enlarged, and the bottom face of a bathtub can be supported firmly. As a result, it can withstand long-term use.

With reference to FIG. 1, the bathtub 1 and the separate leg stand 10 are used. The pedestal 10 includes leg frames 11 and 12, a height adjustment bolt 13, and a horizontal position adjustment bolt 30. A total of five height adjusting bolts 13 are provided at the four corners of the leg frame 11 and near the center of the reinforcing leg frame 12 (13a, 13b, 13c, 13d, 13e). A total of four horizontal position adjusting bolts 30 are provided for each frame of the leg frame 11 (30a, 30b, 30c, 30d).

In the present invention, the bathtub is installed by placing the footrest 10 in the pit so as to be horizontal, then placing the bathtub 1 on the footrest 10, and finally, between the wall and the bathtub. Sealing is performed (reference numeral 37 in FIGS. 6 and 7).

When installing the pedestal 10 in the pit, first, the level is obtained using a height adjusting bolt and a level ruler, and then the pedestal is fixed in the horizontal direction by the horizontal position adjusting bolt. If the footrest is moved horizontally after the footrest height adjustment bolt is obtained by the height adjustment bolt of the footrest, the footrest is not level due to the inclination of the floor surface. Therefore, it is important to determine the horizontal position of the pedestal before placing the bathtub.

Referring to FIG. 2, the height adjustment is performed as follows. The height adjusting bolt 13 includes a support plate 18, a nut 23, and a bolt 14. The material of the height adjusting bolt 13 is preferably made of stainless steel in order to prevent rust and corrosion due to contact with water and to demand strength. The support plate 18 is provided with a bolt receiver 19 having a screw hole 20 at the center and a mounting hole 21. A nut 23 is fitted into the screw portion 15 of the bolt 14, and then a screw hole 20 of the support plate 18 is fitted. Referring to FIG. 3, the leg frame is provided with a mounting hole 26 for mounting the height adjusting bolt. The screw portion 15 of the height adjusting bolt 13 is fitted into the mounting hole 26 of the leg frame, and the height adjusting bolt 13 is screwed to the leg frame 11 with the mounting hole 21. A screw hole 16 is provided inside the screw portion 15. Since the attachment hole 26 of the leg frame 11 opens upward, the screwing position of the support plate 18 and the bolt 14 is changed from above using the wrench 25 that fits the screw hole 16 to adjust the height of the leg base. (FIG. 3). The screw portion 15 is rotatable with respect to the bolt head 17. For this reason, even if the screw portion 15 rotates for such position adjustment after the bolt head 17 has landed on the floor 5, the screw head 17 does not rotate and frictional resistance hardly occurs. After the height is determined, the nut 23 is tightened so that the bolt does not loosen.

Referring to FIGS. 4 and 5, the horizontal position adjustment method is as follows. The horizontal position adjustment bolt 30a is adjusted so that the distance from the pit wall 6 can be maintained while keeping the height-adjusted pedestal so as not to move in the horizontal direction. Next, the bolt 30b is adjusted so that the distance from the pit wall 7 can be maintained. Finally, positioning is performed so that the distance between the bolt 30c and the pit wall 8 and the distance between the bolt 30d and the pit wall 9 can be maintained, and the screw is firmly screwed. When the bolt 30 is stopped on the pit wall, the surface pressure at the lower end of the bolt with respect to the pitch wall is reduced by attaching a nut 31 to a portion in contact with the wall.
