Description

[Detailed Description of the Invention] This invention is for attaching a sink of a sink, a tub of a bathtub, a sink of a washstand, etc. to a support member such as a top plate of a sink, a flange of a bathtub, a top plate of a washbasin, etc. Regarding the mounting structure, it is particularly characterized in that the tank body and the support member can be reliably connected, and furthermore, the two can be easily separated if necessary.

Conventionally, the tank body and supporting member were fixedly connected by welding or interlocking, but when the tank body is made of enamel, there is a risk of damage or peeling of the enamel layer during connection. There is a risk that
Another disadvantage was that when the enamel layer was damaged or peeled off, only the tank body could not be replaced. Therefore, a structure has been proposed in which the tank body and the supporting member can be attached and detached using tightening means such as bolts, but since it is necessary to prevent the tightening means such as bolts from being exposed on the surface of the product, The mounting structure became extremely complicated and required a large amount of space on the back of the product.

The present invention eliminates the above-mentioned drawbacks found in the conventional attachment structure between the tank body and the support member, has a simple structure, easily and reliably connects the tank body and the support member, and also connects the tank body and the support member. The support member can also be easily separated, and will be described in detail below with reference to the drawings. Although the following description will be made regarding the connection between the top plate of the sink and the sink, the present invention is not limited to this, and the present invention is not limited to this, and the present invention is also applicable to the connection between the tub part of the bathtub and the flange part, and the connection between the sink and the top plate of the washstand. It is applicable to any product as long as it is a connection between a tank and a support member that supports the tank, such as connection with a tank.

Referring to the drawing, 1 is the top plate of the sink,
It is made of a metal plate material such as stainless steel, and has an opening 3 in the center for mounting a sink 2 at a proper location.

The sink 2 is a rectangular tank with an open top surface formed by press-forming a metal plate such as a stainless steel plate or a common steel plate, and is preferably enamel-drawn and has an enamel layer on the surface.

At the periphery of the opening 3 of the upper plate 1, there is an engaging piece 4 that slopes outward and downward, as shown in FIGS. 2 and 3.
are formed continuously and integrally. Furthermore, a connecting piece 5 is integrally formed at the upper end of the peripheral wall of the sink 2, which is folded back outward in an inverted U-shape and further extends outward horizontally. The upper surface of the connecting piece 5 has a groove 6 for receiving a water sealing member 7 such as a water sealing packing or caulking material.
is formed.

When the upper plate 1 and the sink 2 are combined, the engaging piece 4
and the connecting piece 5 are in contact with each other, and a space having a substantially triangular cross section formed by the groove 6 is defined between the lower surface of the engaging piece 4 and the upper surface of the connecting piece 5. The water sealing member 7 deforms and comes into close contact with the engaging piece 4 and the connecting piece 5, thereby ensuring watertightness between the two pieces 4 and 5.

The upper surface of the engaging piece 4 and the lower surface of the connecting piece 5 are
When the two pieces 5 come into contact, they have a wedge shape, and when they receive the tightening force of the tightening band 8 that fits on the outer surfaces of the wedge-shaped engaging piece 4 and the connecting piece 5, the pieces 4 and 5 approach each other. This compresses the water-sealing gasket 7 located between the two pieces 4 and 5, thereby achieving the joining of the two pieces 4 and 5 and the water-sealing.

As shown in the figure, the tightening band 8 is made of a metal strip made of stainless steel or the like and has a cross-section shaped like this, and extends along the outer periphery of the joint between the upper plate 1 and the sink 2.

The tightening band 8 is made up of a plurality of members obtained by cutting the outer circumferential surface of the joint portion of the upper plate 1 and the sink 2 into a plurality of parts, and when assembled, it takes on a ring shape. When assembled into a ring shape, the tightening band 8 has a circumferential length that is slightly shorter than the outer circumference of the connecting portion, and therefore, when attached to the connecting portion, each member constituting the tightening band 8 A slight gap occurs between 8a and 8b. Then, by tightening with a suitable tightening means 9 so as to reduce this gap, a force is applied to the engaging piece 4 and the connecting piece 5 in a direction in which both pieces approach each other. 5. A strong bond and water sealing effect are achieved.

As shown in FIG. 4, various aspects were considered for the cutting shapes of the plurality of members constituting the tightening band 8.
It may have any shape.

In FIG. 4, A is a shape that is divided into two parts, left and right, on a line passing through the center of the tank body, and B is a shape that is further divided into four parts on two lines that are perpendicular to each other. Further, C indicates a shape in which the tank body is divided into two parts on a diagonal line, and D indicates a shape in which the tank body is divided into four parts.

The reason why the tightening band 8 is configured to have a plurality of divided shapes is that the tightening band 8 is made of a metal plate and cannot be bent or curved when attached to a joint part. This is due to the fact that it becomes difficult. Therefore, if the tightening band 8 is made of a bendable material, can apply a sufficient tightening force to the joint part, and has sufficiently high rigidity, it is possible to Of course, it is also possible to construct a single ring-shaped member by cutting only one part.

One side of the tightening means 9 which brings the members 8a, 8b of the tightening band 8 closer together is shown in FIGS.
This consists of a metal fitting that fixes a hook 10 to the opposing ends of each member 8a, 8b, and fits between the hooks 10, 10 to bring the two pieces closer to each other. However, it is needless to say that the present invention is not limited to this, and the members 8a and 8b may be brought close to each other using bolts and nuts. In short, any fastening means may be used as long as both members 8a and 8b can be brought close to each other and can be easily attached and detached.

7 to 10 show modifications of the mounting structure of the sink and the upper plate according to the present invention.
In the figure, the engagement piece 40 at the opening periphery of the upper plate 1 is inclined inward and downward, and its end extends outward horizontally, and the connecting piece 50 at the upper end of the sink 2 extends horizontally outward, with its outer end slightly raised vertically, and both pieces 40, 5
A ring-shaped intervening piece 60 is interposed between the two pieces 40 and 50, and between the upper surface of the water sealing member 70 inserted on the upper surface of the engaging piece 40 and the lower surface of the connecting piece 50. A tightening band 80 having a square cross section is fitted into the hole. When the tightening band 80 is tightened, a force is generated between the tightening band 80 and the slope of the water sealing member 70 that causes the pieces 40 and 50 to approach each other.
0.50 are firmly joined.

FIG. 8 shows that the horizontal side of the connecting piece 51 of the sink 2 is bent downward and formed into a shape that rises obliquely, and a water sealing member 71 is inserted on the upper surface of the connecting piece 51, so that the cross-sectional shape is The engagement piece 41 and the connection piece 51 interpose the water sealing member 71 by the wedge action of the slope between the tightening band 81 and the connection piece 51. They approach and are joined.

In Figure 9, the upper end of the sink 2 can be positioned at approximately the same height as the upper plate 1. Therefore, the upper end of the sink 2 is terminated at approximately the same height as the upper plate 1, and the upper end of the sink 2 is terminated at approximately the same height as the upper plate 1. It is folded back into a U-shape, and its end extends horizontally to form a connecting piece 52, and the opening periphery of the upper plate 1 is formed into an engaging piece 42 that is inclined outwardly and downwardly as shown in FIG. A water sealing member 72 is interposed in the triangular space created between the two pieces 42 and 52, and is tightened and fixed with a tightening band 82 having a <-shaped cross section. In this modification as well, a wedge action occurs on the slopes of the tightening band 82 and the engagement piece 42, as described above, and the two pieces 42, 52 are firmly joined to each other.

FIG. 10 shows a modification of FIG. 9 in which the upper end of the sink 2 is formed into an arc shape so that it is flush with the upper plate 1, and other points are the same as in FIG. 8. .

It goes without saying that the structures of the engaging piece 4 of the upper plate 1, the connecting piece 5 of the sink 2, and the tightening band 8 are not limited to those described above;
Any structure may be used as long as the pieces 4 and 5 come close to each other and the water sealing member 7 achieves a water sealing effect when a tightening force is applied.

As explained above, according to the tank mounting structure of the present invention, the tank and the supporting member that supports the tank can be tightened by reducing the circumferential length at the joint portion, thereby exerting a tightening force. The connecting parts of the tank body and the supporting member are brought close to each other by the tightening force of the tightening band, and the water sealing member is compressed by the approach of both joint parts, and the water sealing effect is performed. Therefore, the connection between the tank body and the support member and the water sealing between the connection parts can be achieved only by the tightening force of the tightening band, and the structure is simple and the installation is reliable. In addition to being able to provide a structure, the space required for the mounting structure is small because it is connected only by tightening with a tightening band. Further, since the tank body and the support member can be easily separated by removing the tightening band, there is an advantage that the tank body can be easily replaced. As a result, even if, for example, the tank is an enameled product and the enamel layer is damaged during installation or use of the tank, the tank can be easily replaced. Furthermore, since the tank body can be easily attached and removed, there is no need to assemble the tank body and the support member in advance during the factory manufacturing process, and they can be attached at the time of installation, making transportation and storage convenient. In addition, the upper end of the tank body is the joint part with the support member, and when it is joined, the tip of the tank body enters into the joint part, so if the tank body is an enamel product and the enamel coating on the tip part is unsightly. Even so, it has the advantage of being able to hide it. Furthermore, since the support member and tank body are easily removable, they can be combined freely while considering changes in design, material, etc., and can meet the diverse needs of users. .
