Description

[Detailed explanation of the idea] The present invention relates to an improvement of a bathtub.

When transporting a bathtub into a bathroom, if the entrance is narrow, it is common practice to remove the bathtub apron outside the bathroom before transporting it. You can easily remove the apron to make it easier to clean the bathroom floor later, or to be able to remove the apron and pick it up if you drop it under the bathtub. It is important to make it removable.

There is a structure that allows the apron to be attached and removed freely, with the apron being screwed to a support fixed to the bottom of the bathtub body, etc. However, in the case of a structure where the apron is screwed from the front side, the screw head is It doesn't look good because it's exposed, and even if the screws are screwed from the underside of the apron, it's hard to see the screws directly, making it difficult to tighten the screws, and the gap between the bathtub and the bathroom floor is narrow. In some cases, tools and hands are not available for screwing, resulting in inconveniences such as having to move the bathtub to work, and furthermore, since screws are used, it is easy to lose the screws.

In order to solve these inconveniences, a conventional structure in which the support is provided with a groove and the lower part of the apron is fitted into the groove to fix the apron, instead of being screwed, is as shown in Fig. 1. There is a structure in which a key-shaped part 4 is screwed onto the lower part of the apron 3, and this key-shaped part 4 is locked in the groove 2a of the support 2 attached to the lower part of the bathtub body 1. This has the disadvantage that it takes a lot of man-hours to attach the key-shaped part 4 to the apron 3, and as shown in FIG. There were many problems, such as the work being difficult to perform and the strength remaining unsatisfactory.

In view of the above-mentioned disadvantages, the present invention provides a downward protrusion on the lower surface of the apron, integrally with the apron, a sloped side of the protrusion on the side of the washing area, and an edge in the depth direction of the groove of the support. By devising the length and shape of
The purpose is to provide a bathtub in which the apron fits snugly into the support, is easy to mold and assemble, and is easy to attach and detach the apron at the installation site. This will be explained with reference to the drawings and FIG.

As shown in FIG. 3, a downward protrusion 11a is provided at the tip of the lower surface of the apron 11, integrally with the apron 11.The shape of the protrusion 11a is such that when the apron 11 is attached to the bathtub body 1, the edge on the washing area side 11a' has a slope α.

The support 10 has one end fixed to the bathtub body 1 by means such as screwing, and the other end supports the apron 11, and the protrusion 11a of the apron 11 fits into the support 10.
fR10a is provided.

Here, the protrusion 11a of the apron 11 and the groove 1 of the support 10
The dimensions and shape of 0a are set as follows.

That is, the height of the side 10a' on the bathtub side in the depth direction of the groove 10a of the support 10 is a, the height of the side 102'' on the washing area side is C, and the apron 11 in FIG. The dimension from the bottom of 1 lOa of the support 10 to the top of the protrusion 11a of the apron 11 when the apron 11 is lifted upward to the maximum when attached to When the dimension to the upper end surface of the apron 11 is b, c < b <
The dimensions and shape shall be such that the formula a holds true.

With such dimensions and shapes, even if the apron 11 is pressed against the bathtub body 1 side with the apron 11 lifted to the maximum, the 1 loa side 10a' of the support 10 acts as a stopper to define the position. Therefore, if you lower the apron 11 as it is, it will serve as a guide to keep it in place.

Furthermore, the washing place side side 10a of the groove 10a of the support 10"
, the washing area side side 11a of the protrusion 11a of the apron 11
By providing a slope α having the same angle as ′, the two will fit snugly together, and a reliable fit that will not cause looseness or the like can be achieved.

As mentioned above, the present invention has a protrusion that extends downward integrally with the apron on the lower surface of the apron, making it easy to mold and eliminating the need for man-hours for attaching key-shaped parts, etc., as in the past. In addition, since the dimensions and shapes of the groove of the support and the protrusion of the apron are set as described above, <c<b<a, it is easy to insert the apron, and it is possible to insert the apron easily when the apron is lifted up to the maximum. Even if the apron is pushed toward the bathtub body, the side of the groove on the support tool on the bathtub side acts as a stopper and defines the position, so the apron can be easily placed in the correct position by simply lowering the apron.

Furthermore, by forming the slope of the same angle on the side of the protrusion of the apron on the side of the washing area and the side of the groove of the support on the side of the washing area, the two will fit snugly, ensuring a secure fit without wobbling. It will be possible to do so.

Claims (1)

[Claims for Utility Model Registration] In a bathtub in which the upper part of the apron is fitted onto the bent edge of the upper part of the bathtub body, and the apron is supported by a support attached to the lower part of the bathtub body, the apron is integrated with the lower surface of the apron. The dimension and shape of the downward facing protrusion provided on the support and the groove provided on the support to fit the protrusion are c > b > a. However, in the formula a: height of the side of the groove on the support on the bathtub side Dimension B: Dimension from the bottom of the support groove to the top of the apron protrusion when the apron is attached to the bathtub and lifted upward to the maximum C: Height of the side of the support groove on the washing area side A bathtub characterized in that it is formed so that the dimensions of the bathtub are carefully determined, and that the sides of the protrusions on the side of the washing area and the sides of the grooves on the side of the washing area are sloped.
