[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement in a bathtub lid.

[0002]

[Prior art]

 In addition to traditional wooden boards, the lids for bath tubs are now made by applying synthetic resin to the surface of compression plywood, or as shown in the partial cross-sectional view of FIG. The mainstream is a lid 1 with a thickness of about 4.5 mm in which the peripheral edge of the main body part made of a composite by heat-bonding an aluminum plate 3 with a thickness of about 0.2 mm on both sides of the lid is about 4.5 mm thick. .

[0003]

[Problems to be solved by the device]

 However, in such a conventional bathtub lid, for example, the lid with aluminum on the surface is heavy and inconvenient to handle, and because it has good heat conduction, is cold, and has poor heat retention, it is easy to cool the hot water in the bathtub. There are drawbacks. In addition, not only those made of compressed plywood are heavy, but when scratched, water penetrates from the area and corrosion occurs. Further, these conventional lids have drawbacks such as difficulty in patterning and lack of design.

In addition, since the lid 1 has a large degree of expansion and contraction when a thermoplastic resin is used as the base material, warpage occurs in the entire lid, and if ordinary foam polystyrene is used for weight reduction, the lid 1 shrinks depending on the temperature in the bath. Leading to. There is also the problem of moisture absorption from the wound.

Therefore, the present invention uses a thermosetting resin to solve these problems, is light and easy to handle, is highly heat-retaining, does not warp or shrink due to temperature, does not absorb moisture, and has high pressure resistance. The purpose is to provide a bathtub lid at a low cost.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention fixes a rim material made of soft synthetic resin to the peripheral edge of a lid body having a thermosetting foam synthetic resin substrate and a pair of decorative plates sandwiching the substrate. This is a bathtub lid characterized in that

Further, according to the present invention, an edge member made of a soft synthetic resin is fixed to a peripheral edge portion of a lid body having a substrate made of a thermosetting foam synthetic resin and a pair of aluminum plates sandwiching the substrate. And a lid for a bathtub.

The substrate of the bath lid is characterized in that it is a foam made of closed cells.

【Example】

 1 is a perspective view of a lid 10 showing an embodiment of the present invention, FIG. 2 is a perspective view showing its usage, and FIG. 3 is a vertical sectional view taken along the section line III-III of FIG. is there .

As shown in these figures, the lid 10 of the present invention is formed by arranging a plurality of the lids (two pieces in the embodiment) in abutment with each other so as to cover the upper opening surface of the bath 8 and heat curing. A synthetic resin edge member 14 is fixed to a peripheral edge portion of a lid main body 13 having a substrate 11 made of a synthetic foaming synthetic resin and a decorative plate 12 mounted vertically with the substrate 11 interposed therebetween. In a preferred embodiment, the substrate 11 is a foamed styrene having a thickness of 8 mm to 10 mm, and a decorative plate 12, which is a melamine resin plate having a standard thickness of 1 mm, is integrally fixed to both surfaces thereof with a binder 15. The lid main body 13 having a thickness of 11 to 13 mm is configured.

The substrate 11 is a heat-resistant foamed resin plate that has been heat-treated so as not to shrink even at high temperatures of 80 ° C. to 100 ° C., has a low thermal conductivity, is light, and is resistant to oil and chemicals. Rich. The substrate 11 can be formed by using, for example, a heat pole (trade name) manufactured by Mitsubishi Yuka Verdish Co., Ltd. as a material. The foamed styrene plate is a foam made of closed cells. Therefore, there is no risk of moisture penetrating into the bubbles. In addition, the board 11 clears the accreditation criteria specified by the SG mark (Safety Goods mark established by the Product Safety Center) and the bending deflection amount is 1/10 or less (where 1 is the span in the width direction of the lid). Moreover, it is much lighter than the compression plywood. By the way, the confirmation method of the above certification criteria is that the test specimen is placed on a metal rod placed on the side of the bath, and the deflection of the test specimen when the hot water temperature in the bath is heated to 75 ° C for 1 hour or more. The difference between the amount of bending and the maximum amount of bending after 3 minutes when the load of 30 kg is applied to the test piece through the wooden mounting plate is defined as the bending amount of bending. In order to manufacture such a styrofoam plate 22, as shown in FIG. 4, the material of the styrofoam block body 21 having a thickness T of, for example, about 400 mm is formed in the same manner as described above according to the cutting line 23 shown. It is easily achieved by cutting with a hot wire to a thickness of -10 mm.

FIG. 5 is a vertical sectional view of the decorative plate 12. As shown in this figure, the decorative plate 12 has a pattern formed between, for example, a transparent melamine resin plate 18 and a laminated body 19 made up of about 10 plate-shaped bodies obtained by impregnating kraft paper with a phenol resin. The melamine resin-impregnated paper 20 is hot pressed with the transparent melamine resin plate 18 facing the front. Melamine resin is a thermosetting resin obtained by addition condensation reaction of melamine and formaldehyde, and has excellent water resistance and heat resistance.

An epoxy-based adhesive is preferably used as the binder 15, and the lid main body 13 is made rigid by applying a curing adhesive by mixing two liquids to a thickness of about 0.2 mm and curing it. Deformation is prevented.

The edge member 14 fixed to the peripheral edge of the lid main body 13 is made of soft vinyl chloride and is preliminarily formed to be about 10% smaller than the shape of the peripheral edge of the lid main body 13. After heating and softening, a hardening type one-component type or two-component mixing type adhesive is externally fitted to the peripheral edge portion and is cured at room temperature. By this curing, the edge member 14 contracts and is tightly fitted and fixed to the peripheral edge of the lid body 13.

In the bathtub lid 10 of the present invention having the above-described structure, the foamed polystyrene plate 22 serving as the substrate 11 is light and easy to manufacture and is a foamed body composed of closed cells. Even when the surface decorative plate 12 is flawed, it does not absorb water and is not thermally deformed.

Further, the decorative board 12 has excellent water resistance and heat resistance, and the internal melamine resin-impregnated paper 20 is arbitrarily patterned so that it can be seen through from the surface of the melamine resin board 18, so that the pattern disappears. It is beautiful and rich in design.

Since the edge member 14 has water resistance and is watertight to the lid body 13, the permeation of water into the gap between them is prevented.

Therefore, the lid 10 of the present invention has the features that it has rigidity, is not dented or deformed even when pressed, has excellent heat retention, is lightweight, and is easy to handle.

Other than the above embodiment, the lid body 13 may be an aluminum plate material having a thickness of 0.2 mm fixed to the substrate 11 using an epoxy adhesive instead of the decorative plate.

As the material of the substrate 11, a thermosetting foam synthetic resin plate other than styrene is also used. The edge member 14 may also be a soft synthetic resin other than vinyl chloride.

[0023]

[Effect of device]

 As described above, the bathtub lid of the present invention has the closed-celled and heat-treated thermosetting synthetic resin plate as the substrate, and the decorative plate having excellent design is fixed on both sides of the substrate. Since the main body is formed and the edge material made of soft synthetic resin is tightly fitted and fixed to the peripheral edge portion of the lid main body, the entire lid is light and has excellent water resistance, it is difficult to keep hot water in the bathtub, and warpage due to heat In addition to shrinkage, even if it is damaged, water will not penetrate from its location and corrosion will not occur, resulting in high durability and many other effects. Moreover, according to the present invention, the product can be beautifully finished by patterning and can be provided at low cost as a high quality product. On the other hand, when an aluminum plate is used instead of the decorative plate, the surface strength is high and cost reduction can be expected.
