[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention is used for a sink, a wash basin, etc. using a post-form top plate with a decorative plate or an artificial marble top plate, and relates to a mounting structure of a think tank and a top plate of different materials. .

[0002]

[Prior art]

 Generally, in a sink or washbasin, a top plate with a decorative plate or a top plate made of artificial marble is used because of design requirements, and the think tank mounting hole formed in the top plate is different from the top plate. In many cases, a material think tank is attached and fixed.

Conventionally, as a structure for attaching the think tank and the top plate, for example, the structure shown in FIG. 5 or the structure shown in FIG. 6 is known (Japanese Utility Model Publication No. 63-29027). That is, in the former case, the think tank 22 having the flange 22a is inserted into the think tank mounting hole 21 formed in the top plate 20 from above, the flange 22a is locked to the upper surface of the inner peripheral edge of the think tank mounting hole 21, and the bolt etc. The think tank 22 is fixed to the top plate 20 via the fixing tool (not shown). In the latter case, the flange 22a of the think tank 22 is applied from below to the lower surface of the inner peripheral edge of the think tank mounting hole 21 formed in the top plate 20, and the sealing material 23 is provided between the flange 22a and the top plate 20. The sink tank 22 is waterproofed and fixed to the top plate 20 by filling a fixture 24 composed of bolts, screws and a presser foot and a resin 25.

However, in the conventional mounting structure of the think tank 22 and the top plate 20, since the step G is formed between the flange 22a of the think tank 22 and the top surface of the top plate 20, the step difference is generated. It is extremely unsanitary because dust and water may collect in the G area. In particular, the former (shown in FIG. 5) mounting structure has a problem that when water is collected in the step G portion, water may permeate from the space between the flange 22a and the top surface of the top plate 20 to the back surface side. Further, when the step G is generated, the aesthetic appearance is deteriorated, and there is a problem in terms of design.

[0005]

[Problems to be solved by the device]

 The present invention has the above-mentioned problem in the conventional structure of attaching the think tank and the top plate, that is, since a step is formed between the flange of the think tank and the top surface of the top plate, dust, water, etc. may collect in the step part. It is intended to solve problems such as deterioration of aesthetics due to steps and steps, and prevent dust and water from accumulating between the flange of the think tank and the top plate, and improve the aesthetics. It provides a mounting structure for the think tank and the top plate.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the installation structure of the think tank and the top plate of the present invention has a think tank having a flange; a think tank mounting hole, and a flange of the think tank is fitted on the upper surface of the inner peripheral edge of the think tank mounting hole. And a circular waterproofing agent injecting groove is formed in the notch, and bolt through holes are formed at a constant pitch, and a waterproofing agent injecting into the waterproofing agent injecting groove. ; Fixed on the back surface of the flange of the think tank at a fixed pitch, inserted through the bolt through holes and tightened with the nut so that the upper surface of the flange and the upper surface of the top plate are continuous and the same surface. The stud bolt is composed of resin that fills the gap between the think tank and the inner peripheral surface of the think tank mounting hole. Further, it is preferable that the flange of the think tank is inclined so as to be gradually lowered inward.

[0007]

[Action]

 Insert the think tank into the think tank mounting hole of the top plate and the stud bolt into the bolt through hole, and inject the waterproof agent into the waterproof agent injection groove, and then put the nut on the tip of the stud bolt that protrudes to the back side of the top plate. The flange and the top plate are tightened and fixed so that the upper surface of the flange and the upper surface of the top plate are continuous and flush with each other by the nut and stud bolt. In the mounting structure of the present invention, since the upper surface of the flange of the think tank and the upper surface of the top plate are continuous and flush with each other, dust and water do not collect at the abutting portion of the outer peripheral edge of the flange and the top plate. , Very hygienic. In addition, since the waterproof agent and resin are filled between the think tank and the top plate, it has excellent sealing performance. In addition, the upper surface of the flange and the upper surface of the top plate are continuous and in the same plane, which improves aesthetics. However, when the flange is slightly inclined inward, the drainage becomes extremely good.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 to 4 show a case where the mounting structure of the present invention is applied to a sink, 1 is a sink tank, 2 is a top plate, 3 is a stud bolt, 4 is a nut, 5 is a washer, and 6 is a waterproofing agent. , 7 are resins.

The think tank 1 is made of a stainless steel material like a conventionally known one, and a flat plate-shaped flange 1a is formed on an outer peripheral edge portion of the think tank 1 so as to be gradually lowered inward. ing. The inclination angle of the flange 1a is set so that the water on the upper surface of the flange 1a smoothly flows into the think tank 1.

The top plate 2 is formed by adhering a decorative plate 9 made of melamine, aluminum, stainless steel or the like on the outer surface of a base plate 8 made of plywood or particle plate having an appropriate thickness, and has a rectangular shape. It is finished. A sink tank mounting hole 10 into which the think tank 1 is inserted is formed in the center of the top plate 2, and a notch into which the flange 1a of the sink tank 1 is fitted is formed on the upper surface of the inner peripheral edge of the think tank mounting hole 10. 11 is formed in a ring shape. The width W of the notch 11 is set to be substantially the same as the width of the flange 1a of the think tank 1, and the depth H of the notch 11 is set to be slightly larger than the thickness of the flange 1a. That is, the width W and the depth H of the notch 11 are such that when the flange 1a is fitted in the notch 11 and the flange 1a and the top plate 2 are fastened with the stud bolts 3 and the nuts 4, the back surface of the flange 1a is The outer peripheral edge of the flange 1a is abutted against the end surface of the decorative plate 9 while being in contact with the notch 11, so that the upper surface of the flange 1a and the upper surface of the decorative plate 9 are continuous and substantially flush with each other. Further, a waterproof agent injecting groove 12 having an appropriate depth is formed in an annular shape on the upper surface of the notch 11, and a bolt through hole 13 is formed at a constant pitch inside the waterproof agent injecting groove 12. Has been drilled. Further, on the back side of the notch 11, nut housing holes 14 communicating with the bolt through holes 13 are formed at the same pitch as the bolt through holes 13.

The stud bolt 3 is made of stainless steel or the like, and one end of the stud bolt 3 is fixed to the back surface of the flange 1 a of the sink tank 1 by welding or the like at the same pitch as the bolt through hole 13. It can be inserted. The nut 4 and the like screwed to the stud bolt 3 are also made of stainless steel or the like.

The waterproofing agent 6 is made of a silicone sealing material that can maintain elasticity without being completely cured, and the resin 7 is made of urethane resin, epoxy resin, polyester resin or the like. ing.

Next, a case where the think tank 1 is attached to the top plate 2 will be described. First, the stud bolts 3 are fixed to the back surface of the flange 1a of the think tank 1 by welding at the same pitch as the bolt through holes 13 to correct the distortion of the think tank 1 due to welding or the like. Next, the think tank 1 is inserted into the think tank mounting hole 10 of the top plate 2, and the stud bolt 3 is inserted into the bolt through hole 13 to fit the flange 1a into the notch 11, and the waterproof agent injection groove 12 is waterproofed. An appropriate amount of the agent 6 is injected. At this time, the outer peripheral edge of the flange 1a is projected slightly above the upper surface of the decorative plate 9 due to the inclination of the flange 1a itself and the injection of the waterproofing agent 6. After that, the nut 4 is screwed onto the tip of the stud bolt 3 which is projected into the nut housing hole 14, and the nut 4 is tightened to appropriately tighten and adjust the flange 1a and the top plate 2. That is, as shown in FIG. 3, the tightening amounts of the stud bolt 3 and the nut 4 are adjusted so that the upper surface of the flange 1a and the upper surface of the top plate 2 are continuous and substantially flush with each other. Finally, the gap between the inner peripheral surface of the sink mounting hole 10 and the sink tank 1 and the nut storage hole 14 are filled with an appropriate amount of resin 7.

In this sink, since the upper surface of the flange 1a of the think tank 1 and the upper surface of the top plate 2 are continuous on substantially the same plane, there is no possibility that dust, water, etc. will accumulate in this portion, and it is extremely hygienic. is there. Also, since the flange 1a is slightly inclined inward, drainage is also very good. Further, since the waterproof agent 6 and the resin 7 are filled between the think tank 1 and the top plate 2, the sealing property is excellent. Of course, since the upper surface of the flange 1a and the upper surface of the top plate 2 are substantially continuous with each other, the appearance is improved. In addition, since the nut storage hole 14 is also filled with the resin 7, the nut 4 does not loosen and rattling occurs between the think tank 1 and the top plate 2.

In the above embodiment, the think tank 1 made of stainless steel is attached to the top plate 2 attached to the decorative plate 9. However, the materials of the top plate 2 and the think tank 1 are the same as those in the above embodiments. The material is not limited, and any material may be used as long as the materials of the top plate 2 and the think tank 1 are different. For example, the think tank 1 may be made of a steel plate, and the top plate 2 may be a so-called artificial marble top plate 2 made of acrylic or polyester.

Further, although the flange 1a of the think tank 1 is slightly inclined in the above embodiment, in another embodiment, when the flange 1a is formed horizontally and is attached to the top plate 2, The upper surface of the flange 1a and the upper surface of the top plate 2 may be completely flush with each other.

Further, in the above-described embodiment, the mounting structure of the think tank 1 and the top plate 2 is applied to the sink, but in other embodiments, the mounting structure of the think tank 1 and the top plate 2 is used as a washbasin. Etc. may be applied.

[Effect of device]

 As described above, the installation structure of the think tank and the top plate of the present invention has a notch into which the flange of the think tank is fitted in the inner peripheral edge of the think tank mounting hole of the top plate and a waterproof agent injection groove into which the waterproof agent is injected. Bolt through holes are formed respectively, and stud bolts that are inserted into the bolt through holes are fixed to the back surface of the flange of the think tank, and the flange of the think tank and the top plate are fastened with stud bolts and nuts with a waterproof agent. Since the upper surface of the flange and the upper surface of the top plate can be formed on the same continuous surface, the upper surface of the flange can be formed on the same surface. As a result, dust and water do not accumulate between the flange and the top plate as in the conventional think tank and top plate mounting structure, which is extremely hygienic. In addition, since the waterproof agent is injected into the waterproof agent injection groove and the gap between the sink tank and the inner peripheral surface of the sink tank mounting hole is filled with resin, the sealing property is extremely excellent. Furthermore, since the upper surface of the flange and the upper surface of the top plate are continuous and in the same plane, the appearance is improved and the design is excellent. However, when the flange of the think tank is inclined so as to be gradually lowered inward, the drainage becomes extremely good.
