Description

[0001]
The present invention relates to a top plate with a curtain plate .
[0002]
[Prior art]
Conventionally, the functional purpose of protecting the base material of the top board from splashed water under the wash counter with the wash bowl attached to the top board, and the design purpose of hiding the lower part of the wash bowl and improving the appearance In recent years, the curtains are often attached to the curved top plate with the front end protruding so that the toilet bowl can be washed without any problem even in a wheelchair. Attempts have been made to bend and attach to a curved surface along a curved portion.
[0003]
[Problems to be solved by the invention]
However, since a conventional curtain board is generally made by bonding a decorative material to a plywood, it is not easily bent even if it is curved in an arc shape because of the high rigidity of the plywood.
[0004]
[Means for Solving the Problems]
The present invention has been studied in view of such circumstances, and is characterized by the following. That is, a groove is cut along the curved portion on the back surface of the top plate that is composed of a decorative material and a wooden base material, and has a curved portion on the front side. 10 to 30 times, with a curtain plate , wherein the end portion of the curtain plate to which a polystyrene foam having a thickness of more than 4 mm and less than 25 mm is bonded is inserted and the curtain plate is suspended in a curved shape It is a top plate. Hereinafter, the present invention will be described in detail with reference to the drawings.
[0005]
FIG. 1 is a sectional view showing the construction of a curtain board 20 according to an embodiment of the present invention. A synthetic resin foam 1 and a decorative board 4 which are rich in elasticity are known adhesives such as a water-based urethane-based adhesive and a urethane type Adhesives, vinyl acetate adhesives, urea adhesives, epoxy adhesives, and synthetic rubber adhesives are used.
[0006]
Examples of the synthetic resin foam 1 include polyurethane foam, polyisocyanurate foam, phenol foam, vinyl chloride foam, polyethylene foam, polystyrene foam, polypropylene foam, urea foam, and the like, which are appropriately selected in consideration of compressive strength and elasticity. Is done.
The thickness of the synthetic resin foam 1 is preferably about 5 to 20 mm. If the thickness is less than the lower limit, the synthetic resin foam 1 is likely to be damaged.
[0007]
Among the synthetic resin foams 1, among others, urethane foam having a foaming ratio of 5 to 25 times, polystyrene foam having a foaming ratio of 10 to 30 times, polypropylene foam having a foaming ratio of 5 to 30 times, etc. are excellent in compressive strength, It is preferable because it has elasticity and is easily bent. In any case, if the expansion ratio is less than the lower limit, the elasticity is poor and bending is difficult, and if the upper limit is exceeded, the compressive strength becomes weak.
[0008]
The decorative board 4 adhered to the synthetic resin foam 1 is a polyester resin decorative board obtained by film forming using an unsaturated polyester resin, or a vinyl chloride resin decorative article using a vinyl chloride resin sheet. Natural wood decorative board using wood, thin wood board, melamine resin decorative board using thermosetting resin such as melamine resin and diallyl phthalate resin, diallyl phthalate resin decorative board, etc. can be applied. A melamine resin decorative board that is excellent in properties, abrasion resistance, impact resistance, water resistance, strength, and hardly scratches is desirable, and a so-called melamine resin decorative board for post-form having flexibility is particularly preferable.
[0009]
FIG. 2 is a perspective plan view in which the curtain plate 20 is attached to the back surface of the top plate 7 of the curved wash counter, and FIG. 3 is a partially enlarged sectional view taken along the line AA in FIG.
[0010]
As the top plate 7, a material obtained by bonding the decorative material 5 and the woody base material 6 is used. As the decorative material 5, in addition to those exemplified for the above-described decorative plate 4, cast products in which a resin such as methacrylic resin or unsaturated polyester resin is cast-molded are used. In particular, cast products that are excellent in stain resistance and abrasion resistance and are not easily scratched, and thermosetting resin decorative boards such as melamine resin decorative boards and diallyl phthalate resin decorative boards are preferable.
[0011]
As the woody base material 6, those in which grooves can be easily formed, such as plywood, particle board, MDF (medium density fiberboard), laminated material, or a composite of these, can be applied. Also known ones can be used. In FIG. 2, the wood base material 6 is used as the base material. However, the wood base material is not particularly limited as long as the groove into which the curtain plate 20 can be inserted is cut. There is no problem even with cast products. The above-mentioned known adhesive may be used for adhesion to the decorative material 5.
[0012]
Although not shown in the drawings, the top plate may be a base plate itself that does not require a bonding process of a decorative material, for example, a plastic casting product such as artificial marble or a laminated material.
[0013]
The top plate 21 with the curtain plate 20 is formed by cutting a groove 8 having a width slightly larger than the thickness of the curtain plate 20 on the back side of the top plate 7 with an NC processing machine along the curved portion of the top plate, and bonding the groove 8 to the groove 8. It is obtained by applying the agent and inserting the side end of the curtain 20 in the longitudinal direction.
[0014]
Hereinafter, the embodiment will be described in detail.
[Example 1]
A curtain foam of the present invention was obtained by bonding a polystyrene foam having a curtain plate thickness of 15 mm and an expansion ratio of 15 to a melamine decorative board for post foam having a thickness of 0.8 mm using a rubber adhesive.
A wash counter with a melamine resin decorative board with a curtain plate of 1.0 mm thick and glued to a 18 mm thick plywood with a synthetic rubber adhesive, and an acrylic wash ball attached to the curved top board protruding from the front end A groove having a width of 18 mm and a depth of 10 mm along the curved portion of the top plate was cut with an NC processing machine on the back surface of the top plate.
Next, a vinyl acetate adhesive was applied to the groove, and the end of the curtain plate was inserted to obtain a top plate with a curtain plate.
[0015]
Comparative Example 1
In Example 1, an attempt was made in the same manner except that a plywood having a thickness of 15 mm was used in place of the polystyrene foam having a foaming ratio of 15, and the curtain was not bent.
[0016]
Comparative Example 2
In Example 1, the same procedure was carried out except that the thickness of the polystyrene foam having an expansion ratio of 15 was changed to 4 mm. However, when attached to the top plate, the strength was weak and the curtain plate was damaged.
[0017]
Comparative Example 3
In Example 1, the same procedure was carried out except that the thickness of the polystyrene foam having a foaming ratio of 15 was 25 mm. However, when attached to the top plate, the strength was strong and the curtain was not bent.
[0018]
【The invention's effect】
The curtain board of the present invention is made of a synthetic resin foam having excellent elasticity and excellent compressive strength as a substrate, and a decorative board is bonded to the surface, so that it has flexibility and strength, and is below the curved wash counter. Can be attached in a curved shape.
[0019]
Further, in the embodiment, the curtain plate is attached to the curved wash counter, but not limited to the wash counter, the one requiring a curved curtain plate, for example, a deformed or curved one with a counter, a table, etc. It can also be applied to. Of course, it is not necessary to attach it to a curved surface, and it can be used when it is attached to a flat surface.
