DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved apron fixing device in a bathing facility comprising a combination of a waterproof pan, a bathtub, and an apron.

[0002]

2. Description of the Related Art As is well known in the art of bathing equipment, a waterproof pan is used when installing a bathtub. The waterproof pan used at this time generally has a bathtub installation part and a washing place adjacent to each other, and a partition part protruding from a boundary between the bathtub installation part and the washing place. In the above, the bathtub is installed on the bathtub installation part of the waterproof pan, and the apron for covering one side of the bathtub is:
It is arranged and fixed over the edge of the bathtub and the compartment of the waterproof pan.

FIGS. 5 to 7 show several examples of a bathtub apron fixing device found in the prior art. In the waterproof pan 1 shown in FIG. 5, the bathtub 5 is installed in the bathtub installation section 2 adjacent to the washing place 3 across the partition section 4, and extends over the edge 6 of the bathtub 5 and the partition section 4 of the waterproof pan 1. The upper end of the apron 7 is locked below the edge 6, and the lower end is fixed to the partition 4 via an angle-type fixing tool 8 and a screw 9.

[0006] In FIG. 6 (waterproof pan is not shown), a fixed tree 10 is attached to one side surface of a bathtub 5, and an apron 7 whose upper end is locked below the edge 6 in the same manner as described above. Is fixed at a predetermined position via a decorative screw 11 which is screwed into the fixing wood 10 through the plate surface.

[0005] In FIG. 7, a sandwiching piece 12 is attached below the edge 6 of the bathtub 5 via a fixed tree 11, and a horizontal locking piece (spring piece) 13 and an apron 7 are attached to the upper end of the apron 7. Angle-type mounting pieces 14 are fixed to the lower end portions of each of them. In the case of this illustrated example, the locking piece 13 is inserted between the fixed tree 11 and the sandwiching piece 12, the mounting piece 14 is screwed to the fixing tool 8 in the same manner as described above, and the apron 7 is set at a predetermined position. Fixed.

[0006]

The bathtub apron preferably satisfies the following conditions. One of them is that, as in the case of the general example, the appearance can be maintained. Another is that the apron can be easily attached and detached, which is required when the apron is removed and the inside area is cleaned. By the way, if the inside area covered with the apron is left for a long time, it emits odor.
Yet another is that the apron can accommodate dimensional variations between the tub edge and the waterproof pan compartment. Although this dimensional variation is not so large, it often occurs with the height adjustment when the bathtub is installed on the bathtub installation portion (waterproof pan).

From this point of view, each of the fixing devices for the bathtub apron shown in FIGS. 5 to 7 has advantages and disadvantages. In the case of the fixing device shown in FIG.
The screw 9 is located at the lower end side of the apron 7 and does not fall within the normal visual range, so that the appearance can be kept. However, when the apron 7 is attached or detached, the insertion, removal, tightening, and relaxation of the screw 9 under the apron 7 are blind. This is not easy because it must be done by touch, and if the above-mentioned dimensional fluctuation occurs due to the height adjustment of the bathtub during installation, the screw insertion hole at the lower end of the apron and the screw hole of the fixture 8 match. Without having to do it again, the height must be adjusted again. In the case of the fixing device shown in FIG. 6, the decorative screw 11 can be easily tightened and loosened, and is not affected by the dimensional variation described above. Since it becomes more prominent and apparent, it cannot maintain its appearance. The fixing device shown in FIG. 7 has the same problem as that shown in FIG.

[0008] In view of these technical problems, the present invention can maintain the appearance in a good appearance, can easily attach and detach an apron, and can cope with dimensional fluctuation between apron fixing portions. It is an object of the present invention to provide a bathtub apron fixing device which can be used.

[0009]

According to the present invention, a bathtub apron fixing device according to the present invention includes a bathtub installation section and a washing place adjacent to each other, a bathtub installation section,
There is a waterproof pan having a section raised from the boundary between the washing areas, a bathtub having an edge on the upper outer periphery, and a planar apron, wherein the bathtub is installed on the bathtub installation part of the waterproof pan.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the apron fixing device for a bathtub according to the present invention will be described with reference to the drawings. The waterproof pan 21 illustrated in FIGS. 1 and 2 is a known or well-known one. That is, the waterproof pan 21 has a bathtub setting part 22 and a washing place 23 adjacent to each other, and a partition part 24 raised from a boundary portion between the bathtub setting part 22 and the washing place 23,
The bathtub installation part 22, the washing place 23, and the partition part 24 are integrally formed.

The apron 25 shown in FIG. 3 in addition to FIGS. 1 and 2 is a plate 25a having a long rectangular shape.
And bent pieces 25b, 25c, 25d, and 25e formed by bending the four sides of the plate body 25a inward, respectively, and the bent piece 25b on the upper side of the apron has an edge. A protruding piece 25f that protrudes upward is formed, and a plurality of slits 25g whose front ends are opened are formed at intervals in the bent piece 25c on the lower side of the apron. Further, a reinforcing piece 25h is attached to the lower surface of the bent piece 25c on the lower side of the apron, along both side edges of the slit 25g.

The fixture 26 illustrated in FIGS. 1, 2 and 4
Are horizontal lower fixed seat 26a and horizontal upper mounting seat 2
6b and a connecting piece 26 extending over both seats 26a and 26b.
c are integrally formed, a plurality of through holes 26d are formed in the lower fixing seat 26a, and a screw hole 26e is formed in the upper mounting seat 26b. Each through hole 26d of the lower fixing seat 26a is for passing a screw 27, and the screw hole 26e of the upper mounting seat 26b has a head 2
The bolt 29 with 8 is screwed.

The bathtub 31 illustrated in FIGS. 1 and 2 is a well-known or well-known one similar to the waterproof pan 21, and has an edge portion 32 on the upper outer periphery thereof.

The above-mentioned waterproof pan 21, apron 2
5. The bathtub 31 and the like are made of a known or well-known material used for them, for example, a synthetic resin, a metal, or the like.

In FIG. 1 and FIG. 2, a bathtub 31 is installed on a bathtub installation section 22 of a waterproof pan 21 by a known means, and an apron 25 is provided as an example as described below.
Are arranged and fixed over the edge 32 of the waterproof pan 21 and the partition 24 of the waterproof pan 21. First, two fixing tools 2 corresponding to the interval between the two slits 25g on the lower side of the apron 25 are provided.
6 are arranged on the partition 24 of the waterproof pan 21, and these lower fixing seats 26 a are fixed to the partition 24 via screws 27. The two fixing tools 26 fixed on the partition 24 of the waterproof pan 21 in this manner are attached to the upper mounting seats 26b.
The bolts 29 with heads 28 are screwed into the screw holes 26e of the upper mounting seats 26b from the lower surface side of the upper mounting seats 26b, respectively. Next, the apron 25 is held in an inclined state as shown by an imaginary line in FIG. 2 between the edge 32 of the bathtub 31 and the partition 24 of the waterproof pan 21. In this state, the protruding piece 25f of the upper part of the apron is set in the bathtub 31. Edge 3 of
2 and the lower part of the apron 25 is moved in the direction of arrow X in FIG. In this manner, the bent piece 25c at the lower portion of the apron is displaced toward the two fixtures 26 while the edge portion 32 of the bathtub 31 and the protruding piece 25f at the upper portion of the apron are relatively engaged with each other, forming the bent piece 25c. The shaft portions of both bolts 29 are fitted into both slits 25g. In the following, the bent piece 25c of the apron 25 and the upper mounting seat 26b of both fixtures 26 are tightened by each bolt 29, and the assembling and fixing of the apron 25 on the waterproof pan 21 are completed.

In the above, the bathtub 31 on the waterproof pan 21
Is high, the tub edge 32
Is higher, the gap G (see FIG. 2) between the bent piece 25c and the upper mounting seat 26b becomes smaller, and conversely, when the bathtub 31 on the waterproof pan 21 is at a lower position, Since the bathtub edge 32 is lowered, the gap G is increased. Therefore, even if the distance (dimension) between the bathtub rim 31 and the waterproof pan section 24 fluctuates when the apron is fixed, such dimensional fluctuation can be absorbed between the bent piece 25c and the upper mounting seat 26b.

When the apron 25 fixed as described above is to be removed, first, each bolt 29 is turned to the arrow Z in FIG.
Then, the lower part of the apron 25 is moved in the direction of arrow Y in FIG. 2 (the direction in which the slit 25g and the shaft part of the bolt 29 are disengaged). 25f is pulled off from under the edge 32 of the bathtub 31.

Projection piece 25 of apron 25 in the present invention
As long as f can be engaged in the edge 32 of the bathtub 31, it may project upward and straight like the illustrated example, or may be bent along the inner surface of the edge. Regarding the fixture 26 and the slit 25g in the present invention, the number of the fixtures 26 and the number of the slits 25g formed in the bent piece 25c of the apron 25 match each other. Therefore, when there is one fixture 26, there is one slit 25g, and when there are three or more fixtures 26, there are three or more slits 25g. The nut 30 corresponding to the bolt 29
Is fixed to the upper mounting seat 26b as shown in FIG.
The female screw of the nut 30 becomes the screw hole 26e described above. In such a case, the screw hole 26e of the upper mounting seat 26b may be a simple through hole for bolt insertion. It is desirable that the bolt 29 with the head 28 in the present invention has a large head 28 like a thumb screw. In the case of such a bolt 29, the screw can be tightened or loosened with bare hands. In addition, although the reinforcing piece 25h in the present invention is desirable for reinforcing the portion of the slit 25g, this is not inevitable.

[0020]

The bathtub apron fixing device according to the present invention has the following effects. One of them is that the headed bolt is on the bent piece (lower) side of the apron and does not fall within the normal visual range, so that the appearance of the apron from the washroom side can be kept in a good appearance.

The other one is the engagement and disengagement of the upper portion of the apron and the lower surface of the edge of the bathtub, the engagement and disengagement of the slit (lower portion of the apron) and the bolt shaft (fixer side), and the tightening of a bolt with a head. -The apron can be easily attached and detached by these operations such as relaxation. Further, even when the tightening / relaxing of the bolt becomes a blind touch, only turning the bolt at a fixed position does not cause any particular difficulty.

Still another is that, when the distance (dimension) between the edge of the bathtub and the waterproof pan section varies, the dimensional variation can be absorbed between the bent piece and the upper mounting seat. Therefore, it is possible to cope with a dimensional variation between the apron fixing portions.
