Description

[Detailed Description of the Invention] The present invention relates to a bathtub or an apron body for a bathtub.

With the recent trend toward higher quality and more functional bathtubs, a door 4 is attached to the opening 3 cut out in the apron surface 2 of the bathtub 1 from the outside for self-sealing, etc., as shown in Fig. 1. The pipes related to the bathtub can be inspected through the opening 3, or the box 5 separately formed is attached to the opening 3 in FIG. 1, as shown in FIG. Items that can store and store bath products such as soap and shampoo have become popular.

However, in the case of FIG. 1, the opening 3 is simply a notch in the apron surface 2, so when the door 4 is opened, the cut 3a is visible, and even when the door 4 is closed, the door 4 itself is However, since the thickness of the door 4 protrudes beyond the apron surface 2 from above, the side end surface 4a of the door 4 protrudes outward, which is not only unsightly, but also cuts out the flat apron surface 2. As a result, its strength is weakened, and some kind of reinforcement is required around the opening 3.

In addition, a box body 5 separately formed in the opening 3 shown in FIG.
In the configuration in which the apron is attached, it is necessary to attach the box body 5 to the opening 3 which is a troublesome work, and the strength of the apron itself is weakened by notching the apron surface 2 as in the case of FIG. In addition, when bath supplies are stored and placed in the box 5, the load is applied to the apron itself, which requires further reinforcement.

In order to visually hide the cut 3a of the opening 3 and the side end surface 4a of the door 4, to make them invisible and to eliminate the need for reinforcement around the opening 3, simply cut out the flat plate surface as shown in FIG. If a recessed part 6 having a peripheral wall surface 2a continuous to the apron surface 2 is formed instead of a simple opening 3, as shown in FIG. 3, the peripheral wall surface 2a will have a reinforcing effect, and the piping Even if an opening 7 is provided by cutting out the bottom surface 2b of the recessed portion 6 to provide an inspection port, the lower cut a is located further back than the apron surface 2, making it difficult to see, so the above problem is solved. It is.

However, when forming the concave portion 6 having the peripheral wall surface 2a continuously on the apron surface 2, in the case of hand lay-up molding or spray-up molding of FRP, the apron body is molded separately from the bathtub body. If you change the shape of the apron body to ■ shape, L shape, [1 shape, etc., it can be removed from the mold.
Although it is possible to easily form the recessed part 6 having the peripheral wall surface 2a continuous to the apron surface 2, when the apron body is molded integrally with the bathtub body, i.e., the bathtub side wall as shown in FIG. 8. In the case where the upper edge surface 9 and the apron surface 2 are continuous, the peripheral wall surface 2a of the recessed portion 6 becomes an undercut, and the molded product is demolded from the mold 10 in the direction of the arrow. I can't.

Therefore, in a conventional bathtub, if the bathtub side wall 8, upper edge surface 9, and apron surface 2 are continuous as one body, a separately formed box body 5 is attached as shown in FIG.
An apron body in which a recessed portion 6 having a peripheral wall surface 2a continuous to the apron surface 2 is formed is molded separately from the bathtub body, and this apron body is attached to the bathtub body.

Furthermore, even in the case where the bathtub side wall 8, the upper edge surface 9, and the apron surface 2 are molded continuously and integrally, if the purpose is simply to facilitate demolding, an opening in the apron surface 2 as shown in FIG. Steps 11 are provided on both sides and the bottom of 3, and the top is provided with step 1.
There is also a method of not having the step 11a, but in this method there is a design restriction in that the step 11a must be provided in the horizontal direction of the part excluding the upper side of the opening 3. Since the stepped portion 11a is not provided, there is a problem in which strength remains unreliable.

The present invention has been made in view of the above points, and is a bathtub or bathtub in which the bathtub side wall 8, the upper edge surface 9, and the apron surface 2 are continuously and integrally formed as shown in FIGS. 1 to 5. In an apron body 13 of a bathtub in which an inner wall surface 12, an upper edge surface 9, and an apron surface 2 are continuously and integrally formed as shown in FIG. A bathtub or bathtub apron body is formed integrally with the bathtub or bathtub apron body, which eliminates the need for reinforcement and maintains a good design. will be explained using drawings.

FIGS. 7 to 12 show the state of molding and demolding when the bathtub or bathtub apron body of the present invention is molded by hand lay-up molding or spray-up molding.

First, FIGS. 7 to 11 show the molding and demolding state of a bathtub or bathtub apron body in the case where an opening is provided on the apron surface and this opening is intended to be used as an inspection port for piping.
A large piece 15a and a small piece 15b are attached to the frame with bolts 16 and the like.

``The large piece 15a is attached to form a recessed portion, and the small piece 15b is attached to provide an opening and a flange 2c at the bottom of the recessed portion.

First, the dimensions will be explained with reference to FIG. 10. The difference in length between the large piece 15a and the small piece 15b is the length of the flange 2c.

In other words, the length of the large piece 15a...a1 the length of the small piece 15b...b, the length of one flange...c1 the length of the other flange...C', then a-b= It becomes c10'.

Further, it is preferable that the mating part A between the main mold 15 and the large piece 15a be provided inside the apron surface 2 to the extent that it does not interfere with demolding.

That is, when the height of the peripheral wall surface 2a is d1 and the thickness of the large piece 15a is a', the size of the piece is such that d>a' is satisfied.

This is to prevent the split line formed by the joining part A of the main mold 15 and the large piece 15a from appearing on the surface side of the apron as much as possible.

To attach the large piece 15a1 and the small piece 15b to the main mold 15,
Machining female screws etc. on the main mold 15, large piece 15a, small piece 1
The bolt 16 is tightened and fixed through the through hole drilled in the hole 5b.

Further, the large piece 15a1 and the small piece 15b may be attached from the outside of the main mold 15 with bolts, nuts, etc.

After molding a bathtub or an apron body of a bathtub with the mold consisting of the main mold 15, large piece 15a, and small piece 15b, when removing the molded product, use the bolt 16 as shown in FIG.
After loosening and removing the small piece 15b inward, the mold is removed with the large piece 15a still attached to the molded product, as shown in Fig. 9.
Finally, all you have to do is remove the large piece 15a to the outside.

Incidentally, the flange can also be a flange 2C/ as shown in FIG.

Next, the formation of a bathtub or an apron body for a bathtub when a recessed portion 6 having a peripheral wall surface 2a is formed continuously on the apron surface 2 and this recessed portion is used as a storage area for bath supplies will be explained with reference to FIG. 12. , instead of the large piece 15a shown in FIGS. 7 to 11, a thick piece 15c is placed in the main mold 15.
The bolts 16 are tightened from the outside of the molded product, and molding is performed. After molding, the bolts 16 are removed as shown in Figures 8 and 9, and the mold is removed with the piece 15c attached to the molded product. Finally, By removing the top 15c to the outside, a bathtub or bathtub apron body can be obtained in which a recessed portion 6 having a peripheral wall surface 2a continuous with the apron surface 2 is formed.

If molded as described above, a bathtub in which the bathtub side wall, top edge surface, and apron surface are continuously molded as in the present invention, or an apron body in which the inner wall surface, top edge surface, and apron surface are molded continuously. In this case, since a recessed part having a peripheral wall surface continuously formed on the apron surface is formed, by using such a bathtub or bathtub apron body, the bottom of the recessed part can be opened and used as a pipe inspection port. In either case, if the recessed part is used as a storage area for bath supplies, the peripheral wall surface of the recessed part formed continuously on the apron surface serves as reinforcement, so no other reinforcement is required. .

In addition, when the opening at the bottom of the recess is used as an inspection port for piping, the cut of the opening is recessed from the apron surface, so the appearance is not spoiled, and the recess has a peripheral wall surface. Therefore, installing a hinge or the like to allow the door to open and close freely on this surrounding wall surface will make it easier to install the door, and the door can also be fitted into the recess so that the apron surface and the door surface are flush with each other. Since the door can be mounted on the apron, the side end surface of the door does not protrude beyond the apron surface, making it possible to improve the design.

In addition, the flange of the opening shown in the embodiment serves as a holder or stopper for the door when the door is attached to the recess, and also serves as a drainer to prevent water from entering the back of the apron. .

Furthermore, since the split line is located on the peripheral wall surface, if a door is attached to the recessed part, the split line will be hidden by the door, and the appearance will not be spoiled.

Incidentally, the inner surface in the scope of the utility model registration claims of the present invention includes both the bathtub side wall 8 and the inner wall surface 12 in the detailed description of the invention.

That is, the bathtub side wall 8 and the inner wall surface 12 are both located inside the apron surface 2, so they become the inner surface.
