Description

  The present invention relates to a bathtub apron that covers a side surface of a bathtub, and more particularly, to a bathtub apron with a watertight function that is formed so that a gap formed between a side wall panel and the like can be closed in a watertight manner when the bathtub apron is attached.

Conventionally, as this type of invention, for example, there is one described in Patent Document 1.
In this conventional example, the water return member is fixed to the wall, the side end portion of the apron is pressed into the soft portion of the water return member, and the water that penetrates into the back from the pressure contact portion is a claw piece formed on the water return member. It is formed so as to prevent.

Thus, in the invention described in Patent Document 1, the water return member is screwed to the wall, so that a screw hole is made in the wall, and the water return member is positioned on the wall when the bathtub apron is installed. The work involved screwing.
Therefore, according to this, it was unavoidable that the wall was damaged and that it took time and effort to install the bathtub apron.

Conventionally, a joint material used by being inserted into a gap between a bathtub and a wall is also known (for example, see Patent Document 2).
However, in this case, since the head of the joint material is exposed at the entrance of the gap, there is a problem that the design of the gap portion is easily impaired and the appearance is deteriorated.
Also in this case, as in the conventional example of Patent Document 1, it is necessary to perform the water-tightening work by inserting the joint material separately from the installation work of the bathtub apron. It was.

Conventionally, as this kind of bathtub apron, for example, a packing is adhered to a side end face, and it is generally performed to prevent water from entering from the washing area side with this packing.
Thus, in this case, it is possible to close the gap by attaching the bathtub apron, which can be done only once.For example, while the bathtub apron is being attached and detached several times during the inspection of the bathtub, the packing is separated from the wall. It sometimes peeled off due to frictional resistance.
Therefore, according to this, it is difficult to reattach and reuse the packing, and it takes time and effort to install the packing.

Japanese Patent No. 3900130 JP 2002-291642 A

The present invention has been proposed in view of such problems of conventional products.
Therefore, the technical problem to be solved by the present invention is that the gap can be closed watertight at the same time by installing the bathtub apron, and the watertightness can be prevented without damaging the wall or deteriorating the design when viewed from the washing place side. It is an object of the present invention to provide a bath apron with a watertight function formed so that it can be easily and quickly mounted even if a member is peeled.

The present invention employs the following technical means in order to solve the above problems.
That is, as shown in FIG. 1 and the like, the present invention has a watertight function including a watertight member 3 that closes a gap S between the bathtub 1a and other bathroom constituent units 1 and the end 2a of the apron body 2. It is a bathtub apron, and the above-described watertight member 3 is fitted to the back surface 2b or the end surface of the apron main body 2, and a portion 3a of the watertight member 3 that closes the gap S is formed in a flexible fin shape. The surface contact portion 3b with the back surface 2b or the end surface of the apron body 2 connected to the portion 3a of the water-tight member 3 is formed in a hard shape, and the back surface 2b of the apron body 2 or the surface contact portion 3b of the water-tight member 3 A male part 3c for fitting into the female part 4 for fitting on the end face is formed in a protruding shape (claim 1).

  Here, the bathroom component unit 1 includes a side wall panel 1b and a floor pan 1c (see FIG. 14) in addition to the bathtub 1a. Moreover, as the edge part 2a of the apron main body 2, there are an upper end part and a lower end part in addition to the left and right side end parts. In the case of the present invention, the watertight member 3 is usually fitted to the back surface 2b of the apron main body 2, but is not limited to the back surface 2b, and is not limited to the back surface 2b. (Thickness surface) may be fitted.

In this case, in the present invention, it is preferable that the male portion 3c is formed to include a hard shaft portion 3c1 and a drop-off preventing portion 3c2 provided around the shaft portion 3c1. 2 ).
This is because in this case, the drop-off prevention part 3c2 can prevent the water-tight member 3 from dropping out.

In the present invention, it is preferable that the fitting female portion 4 is formed in a groove shape, and the male portion 3c is formed continuously in the longitudinal direction of the watertight member 3 (Claim 3 ).
Because, according to this, compared with the case where the female part 4 is formed, for example, in a hole shape, and the pin-shaped male part 3c is fitted into the female part 4, the fitting strength between the male part 3c and the female part 4 is increased, This is because it can be securely and securely fitted.
The female part 4 is formed in, for example, a dovetail shape or engaged with the tip of the drop-off preventing part 3c2 so that the fitting state of the watertight member 3 with the male part 3c can be made more surely and firmly. Concavities and convexities may be formed in a bowl shape on the inner surface.

Because, according to this, the flexible part 3a of the watertight member 3 disperses the force when the bathtub apron is attached and detached. As a result, it is difficult for the force to be transmitted to the male part 3c, and the watertight member 3 is difficult to come off. This is because damage to the member 3 can be suppressed.

Further, in the present invention, as shown in FIG. 16, the watertight member 3 may be provided continuously around the apron body 2 (Claim 5 ).
In the present invention, the watertight member 3 may be individually provided for each side of the apron main body 2, but in this case, the gap S around the apron main body 2 is reduced at one time and at the corner seam. This is because it can be closed without any problems.

In the present invention, since the watertight member is fitted to the back surface or the end surface of the apron main body as described above, when the bathtub apron is attached or detached for inspection work or the like, it can be easily fitted even if the watertight member is peeled off. .
Therefore, according to this, the watertight member can be reused, and remounting can be simplified and speeded up.
Further, according to the present invention, since the gap can be closed simultaneously by the bathtub apron mounting operation, it is possible to eliminate the trouble of separately performing the watertight operation, and the bathtub installation operation can be performed quickly and efficiently.
In addition, the present invention prevents the head from being exposed in the bathroom unlike a joint material, so that it is possible to prevent impairing the design when viewed from the washroom side, and no screw hole is formed in the side wall panel. Therefore, the side wall panel is not damaged.

In the present invention, the portion of the watertight member that closes the gap is formed in a flexible fin shape.
Therefore, according to this, since the part of the watertight member is in close contact with the wall surface or the like while being bent in accordance with the movement of the apron body, the watertightness is improved. Moreover, according to this, even if there is variation in the width of the gap due to molding distortion of the bathroom constituent unit, etc., it can be absorbed and can be flexibly dealt with.

Further, in this case, the present invention is such that the surface contact portion with the back surface or the end surface of the apron body that is connected to the fin-shaped water-tight member portion is formed in a hard shape, and the surface contact portion of the water-tight member is the back surface of the apron body or A male part for fitting into the female part for fitting on the end face is formed in a protruding shape.
Therefore, in the case of the present invention, since the watertight member has a hard portion, the fitting operation and handling become easy .
