2. Description of the Related Art In manufacturing a sink, which is one of the kitchen facilities, a stainless steel plate or other material that is highly resistant to corrosion is cut into a required size, and a top plate base material is provided with an opening or a sink for the range part. The openings for welding are formed using a punch press, etc., and then the so-called back guard part to prevent the outflow of water, etc. to the rear of the sink and the uneven parts such as the front front drop part are bent by pressing. After making a top plate, we weld the sink and attach various equipment.

The top plate base material is generally rectangular, and is embossed by chemical means or mechanical means, leaving a background portion of approximately the same width on both sides. At that time, there is no particular restriction on the vertical direction of the top plate base material. Necessary drilling and bending are performed on such a top plate base material at a work site. When making a top plate for an ordinary sink, take a bent part of the same width on each side along the upper and lower long sides of a rectangular base material, and in the central area part between the bent parts. The range opening and the opening for mounting the sink by means of welding or the like are formed by machining. Many of the openings have a symmetrical shape in the vertical and horizontal directions, and in many cases, the axis of the opening is slightly deviated from the major axis of the top plate base material. Therefore, after the opening is formed in the top plate base material, the vertical direction of the top plate base material is naturally restricted.

[0004] While paying sufficient attention to the vertical direction of the top plate base material that has completed the opening operation, an operator attaches the top plate base to a processing machine such as a press in order to perform a bending process which is the next work process. The material is set, and as described above, the back guard portion or the front hanging portion is bent. After finishing the press work, required members are attached to the top plate, and thereafter, a sink as a kitchen product is created through several steps.

[0005]

In the manufacturing of the sink top plate manufactured by the above-described working process, the worker, especially the worker who bends the back guard part, the front hanging part, etc., at the time of manufacturing Since the vertical direction of the top plate base material has already been determined by engraving the opening for sink attachment in the previous working process, it is necessary to pay sufficient attention to setting the base material on the press. However, the end plate base material is rectangular, and the opening to be carved has a symmetrical shape in the vertical direction, as described above, provided with a slight deviation from the long axis of the top plate base material. Since it is not present, it is not easy to visually ascertain the vertical direction with certainty, and the base material is sometimes set upside down with respect to the press. As a result, the back guard and the front drooping part are formed at positions reversed from the sink position,
Either it could not be used as the top plate of the sink, or even if it could be used, the design of the sink as a product had to be unfit for its purpose.

The object of the present invention is to solve the above-mentioned inconvenience, and the operator can easily determine the vertical direction of the top plate without the need of paying special attention.
The aim is to obtain a sink top plate that can perform a work process without mistakes and at the same time give the sink top plate as a product a beautiful appearance.

[0007]

In order to solve the above-mentioned problems and to achieve the object, the present invention has a background portion having substantially the same width on both sides, and an embossing is applied between the background portions. One of the boundary portions between the background portion and the embossed portion is provided with a boundary line that is visually distinguishable from the other portion, and a sink portion or the like is attached to the embossed portion. Disclosed is a top plate for a sink, which is provided with holes.

The base material of the top plate is most preferably a stainless steel plate, and any one such as one having a glossy surface, matte one, or hairline finish may be used. There is no particular limitation on the embossing applied between the background portions on both sides, and the embossing can be performed by a conventionally known means. The embossed pattern is also optional. The visually distinguishable boundary line provided on one of the boundary parts between the background part and the embossed part may be a linear body having a structure capable of visually distinguishing the background part and the embossed part, and other Various lines such as a mirror line having different light reflection conditions from a part, a line having embosses of different shapes, a convex line, a concave line, and the like can be applied. This boundary line may be processed at the same time when the surface of the substrate is embossed, or only the boundary line may be provided as a separate step. In addition, the width of the boundary line is arbitrary, but 1
mm is preferable.

When making a sink top plate using this base material for a top plate, an operator engraves an opening for a sink and press-molds a back guard and the like. At that time, since one of the boundary portions between the upper and lower background portions and the central embossed portion is provided with a boundary line of a visually distinguishable structure,
By visually perceiving this boundary line, the operator can identify the vertical direction very easily, and reliably prevent the substrate from being set in the wrong posture for each machine tool. Is possible.

The boundary line of this visually distinguishable structure is
Not only does the operator have the ability to discriminate between upper and lower sides, but it also has other practical effects. Normally, when a stainless steel plate is embossed, the boundary between the background part and the embossed part tends to be unclear.However, by applying the boundary line as in the present invention, the boundary between them can be made clear. It also has the effect of being able to obtain a top plate for a sink with a clear contrast and a superior design.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in more detail based on the description of embodiments with reference to the accompanying drawings. Reference numeral 1 is a stainless steel plate which is a base material for manufacturing a top plate for a sink, and leaves bare portions (mirror surfaces) 2 and 2 ′ of the same width along the long side in the vertical direction, and an embossing 3 in the portion between them. It has been subjected.
On one of the two boundary portions of the embossed portion 3 and the upper and lower background portions 2 and 2 ′ (the upper boundary portion in the figure), a demarcated boundary line 4 is formed.

An opening having central axis L ', L''at a position displaced a little below the position of the central axis L in the longitudinal direction with respect to the top plate base material, in this case, a range opening 5
The opening 6 for the sink is formed by a machine tool such as a punch press. For the top plate base material 1 that has completed the necessary opening work,
Bending is performed by pressing using the boundary line 4 as a guide in the vertical direction. In this embodiment, as shown in FIG. 3, the upper ground portion 2 has a back guard A bent upward in a substantially L-shape, and the lower ground portion 2'has a substantially L downward.
The front sloping portion B bent in a letter shape is bent. Thereby, the top plate for the sink is created. A main body portion of the sink is prepared by welding a separately formed sink body 10 to the sink opening 6 on the sink top plate.

The above example is only one embodiment of the present invention, and there are many other variations. For example, the opening may be only a sink opening, and the boundary line 4 does not necessarily have to be a line obtained by matting. The boundary line 4 can achieve the object of the present invention as long as it is a line body having a configuration capable of visually distinctly distinguishing the background portion and the embossed portion. Further, the boundary line 4 may be provided at the time of performing the opening work or the pressing work, may be performed at the same time as the embossing molding, and may be performed before and after the embossing process by a unique process. Further, a concave line or a convex line may be formed by pressing.

[0014]

The top plate for a sink according to the present invention has a visually recognizable boundary line at one of the upper and lower ground portions and the embossed surface, so that it can be formed as a top plate. In addition to preventing an erroneous operation during processing, the boundary between the background portion and the embossed surface can be made clear, and the contrast can be emphasized. Therefore, the sink as a product has an effect of giving an aesthetic appearance.
