Abstract

PURPOSE: To enhance the productivity of a top panel for a sink cabinet, a wash stand or the like and to reduce the production cost by simplifying the structure of the top panel made of a synthetic resin such as artificial marble, and to eliminate the necessity of manual work under a worse environment such as machining dust floating condition, by enabling machining with the use of an automatic machine tool. CONSTITUTION: Thin wall parts 5, 6 formed along the front and rear end faces of a thermoplastic synthetic resin plate 1 is bent so as to form a front guard 2 and a rear guard 4 of the top panel, and a water deflecting part 5a is formed being projected from the upper surface of the top panel by the use of the thin wall part 5 in a part continuous to the front guard 2, and a round part 6a is formed in the rear of the top panel body 3 by the use of the thin wall part 6 in a part continuous to the rear guard 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling plate such as a sink and a wash basin formed of a thermoplastic synthetic resin such as artificial marble.

[0002]

2. Description of the Related Art Conventionally, as a top plate of this type, a top plate body 30 made of a synthetic resin and formed in a flat plate shape as shown in FIG.
At the front end of the same, a plastic-made water-repellent member 20 made of a flat plate
In some cases, the upper end of the top plate is joined and the back guard member 40 is joined to the upper surface of the rear part of the top plate body 30.

However, this is not only bad in appearance due to the formation of a right angled corner at the joint between the top plate body 30, the water repellent member 20 and the back guard member 40, but there is a liquid detergent or a liquid seasoning here. Dirt due to liquid food (soup, sauce, etc.) easily accumulates, or mold may be generated due to this, and in that case, it is difficult to clean and tends to be unsanitary. It was

Therefore, as shown in FIG.
Of the top plate body 31 in which an inclined portion 21a is provided on the upper end of the back guard member 41, a rounded portion 41a is provided on the front surface of the lower end of the back guard member 41, and engaging step portions 31a and 31b are provided at the joining points.
In some cases, the corners were not formed at the joint by joining to.

[0005]

In the above-mentioned conventional top plate, first, as described above, since the corners are formed at the joint portion as described above, not only the appearance is bad, but also dirt is likely to be accumulated and mold may be generated. As a result, there was a fatal problem as a sink and a wash basin that were unsanitary.

The latter is easy to clean because the joint is smoothly continuous with the top surface of the top plate due to the sloped portion and the rounded portion, but the shape of the member is complicated but the joint is assembled. It also requires a certain degree of dimensional accuracy,
There is a problem that the cost of forming the member increases. In addition, a step 41b may be generated at the joint portion as shown in FIG. 6 or the adhesive 9 may be squeezed out as shown in FIG. 7, so that there is a problem that it takes time to correct or remove these. Moreover, since these corrections and removals must be individually performed manually, not only the work efficiency is poor, but also dust during cutting work may affect the health of workers.

Further, since both the top plates must be formed by joining three members, it is necessary to apply an adhesive and position the members when joining, and a jig is used. There is also a problem in that workability is extremely poor in this respect as well, because it takes time to fix and hold each member using the above, and to dry and solidify the adhesive.

An object of the present invention is to solve the problems that these conventional resin top plates have.

[0009]

In the present invention, the back surface of a thermoplastic synthetic resin plate formed in a flat plate shape is cut to form grooves in the lateral direction near its front end and its rear end. By heating and bending the thin part on the upper side of the groove, a water return part and a front guard continuous with this water return part are formed on the front side, and a rounded part and a back guard continuous with this rounded part are formed on the rear side. By forming it, the said subject was solved.

[0010]

The thin portion formed along the back and front end faces of the thermoplastic synthetic resin plate is heated so that the thermoplastic synthetic resin plate can be bent.
Further, the thin wall portion functions to connect the front guard and the back guard to the main body of the top plate and to form a water return portion and a rounded portion in the continuous portion.

[0011]

1 is a simplified perspective view of a sink top plate according to an embodiment. As shown in the figure, the top plate of the present invention is formed by bending a single flat plate material.

Here, the plate material used for the top plate of the present invention is made of a thermoplastic synthetic resin such as artificial marble (for example, Corian (trade name) manufactured by MRC DuPont).

In the fabrication, first, the thermoplastic synthetic resin plate 1 formed in a flat plate shape is laterally cut into a groove shape in the lower surface near the front end and the lower surface near the rear end, and as shown in FIG. 5 and 6 are formed. Next, the thermoplastic synthetic resin plate 1 is placed at a predetermined temperature (about 135% in the case of the above corian).
To 165 ° C.), and using a guide member such as a backing plate (not shown), the front and rear of the thin portions 5, 6 are bent up and down as shown in FIG. 3 to form the front guard 2 and the back guard 4. . At this time, the curved portion formed by the thin portion 5 continuous with the front guard 2 is slightly projected upward to form the water return portion 5a, and the thin portion 6 between the back guard 4 and the top plate body 3 is formed. The rounded portion 6a having a predetermined curvature is formed. The curvature of the curved portion and the rounded portion 6a is arbitrary, but if it is made too small, whitening or cracks will occur in the curved portion, so the curvature is within the range where these do not occur.

In FIG. 1, reference numeral 7 is a sink, and 8 is a water supply pipe mounting hole provided in the vicinity of the sink 7.

In this way, the top plate of the present invention is formed by cutting and bending one thermoplastic synthetic resin plate, and is mounted on a cabinet such as a sink or a wash basin (not shown).

When the back surface of the front guard or the back guard of the top plate is not held when the cabinet is attached to the cabinet, and the strength of the curved portion is insufficient, a back plate or a metal fitting is appropriately attached to the back surface. Just attach and reinforce it.

As described above, in the top plate of the present invention, the back side of the flat plate material made of thermoplastic synthetic resin is cut along the front and rear end faces thereof, and the thin portion thus formed is heated and curved. Since it is formed only by itself, the work is easy and continuous work by an automatic machine is also possible.

[0018]

As described above, since the top plate of the sink, wash basin, etc. of the present invention is formed by processing one plate material, it does not require a plurality of members as in the prior art and is different. The labor for manufacturing the shaped members is reduced, and the labor for joining and assembling the members is also unnecessary. Therefore, the productivity is improved and the manufacturing cost is reduced.

Further, since the processing is performed only by cutting the back side of the plate material along the front and rear end faces and heating and bending the formed thin portion, the work is extremely easy and efficient.
In addition, it is easy to handle with an automatic machine, and if continuous work is performed with an automatic machine, work efficiency improves and work in cutting dust becomes unnecessary, which may affect the health of workers. Disappear.

Further, since the top plate of the present invention has no joints, the quality of the finished product is improved, and the work of correcting gaps and steps is not necessary. It has many excellent effects that have not been heretofore found to be improved.
