5-7 shows the top plate structure 14 of the sink 1A by 2nd embodiment of this invention.
In the top plate structure 14 according to the second embodiment, a frame 16 having a substantially L-shaped cross section is installed at the rear end of the top surface of the top plate 3 in the laminate of the top plate 3 and the backing portion 5. The frame 16 includes a projecting portion 17 having a length of about 1/2 of the thickness of the back guard 4 installed on the top plate 3 and a back surface portion 18 rising upward. The protruding portion 17 may be fixed on the top plate 3 with an adhesive or the like, or may be placed and fixed to the top plate 3 with a sealing material 12 described later.

Then, the back guard 4 is placed on the projecting portion 17, and the double-sided tape 10 a is attached to the back surface of the back guard 4 to be fixed to the back surface portion 18. Since the protrusion 17 is inserted between the top plate 3 and the back guard 4, a gap 11 is formed between the top plate 3 and the back guard 4. The front side of the gap 11 is filled with the sealing material 12 and solidified. ing.
In the sink 1A according to the second embodiment, the same effect as that of the first embodiment can be obtained.

Next, a sink 1B according to a modification of the embodiment of the present invention will be described with reference to FIGS.
In the sink 1 according to this modification shown in FIGS. 8 and 9, a notch portion 20 is formed in which the rear end portion of the back guard 4 side is cut off at a substantially right angle with respect to the backing portion 5 fixed to the lower surface of the top plate 3. For example, a rectangular tube member 21 having a substantially rectangular tube shape is mounted and fixed to the notch 20. The square tube member 21 is fixed to the top plate 3 and the backing portion 5 on two sides with an adhesive such as an elastic epoxy resin or a screw.
As shown in FIG. 9, the square tube member 21 is attached to a position retracted forward from the rear end portion of the top plate 3 in a state where the square tube member 21 is attached to the backing portion 5.

  A frame 22 having a stepped cross section is attached to the back of the top plate 3 and the back guard 4. In the area of the square tube member 21, the frame 22 has a lower back surface portion 23 having a substantially L-shaped cross section along the side surface of the square tube member 21 and the lower surface of the top plate 3, and a flat upper back surface portion 24 formed on the upper portion. And. Further, a protrusion 25 is formed at a position slightly higher than the top plate 3 on the upper back surface 24, and the back guard 4 is placed on the upper surface of the protrusion 25. The protrusion 25 is formed to have a length that is about half the thickness of the back guard 4.

In the lower back surface portion 23, the surface in contact with the square tube member 21 is fixed to the square tube member 21 with a screw 27. Further, a gap 28 is formed between the top plate 3 and the projecting portion 25 and the back guard 4, and the gap 28 is filled with the sealing material 12, thereby sealing the gap 28 in a liquid-tight manner. Unlike the above-described embodiment, the gap 28 is formed not only in front of the protrusion 25 but also between the protrusion 25 and the top plate 3. Further, a sub-gap 29 is also formed between the rear end surface of the top plate 3 and the lower portion of the upper back surface portion 24.
Therefore, in this modified example, the sealing material 12 includes not only the gap 28 between the top plate 3 and the protruding portion 25 and the back guard 4, but also a small sub-gap between the top plate 3 and the lower end portion of the upper back portion 24. 29 is also filled. The back guard 4 is fixed to the upper back portion 24 of the frame 22 by a double-sided tape 10a.

Therefore, according to the sink 1 </ b> B according to the present modification, the holding strength of the frame 22 is high because the lower back surface portion 23 of the frame 22 is fixed to the square tube member 21 provided on the backing portion 5 with the screw 27. Moreover, since the back guard 4 is not directly fixed to the top plate 3 but is fixed to the square tube member 21 via the frame 22, it can be fixed without being affected by deformation of the top plate 3.
Further, when the rectangular tube member 21 is set flush with the rear end surface of the top plate 3 and the frame 22 is formed in a flat plate shape, if the screw is fixed, the head of the screw 27 protrudes, which requires processing. However, in this modification, the rectangular tube member 21 retracted to the front side is fixed with the screw 27 by the lower back surface portion 23 having a substantially L-shaped cross section of the frame 22, so that the upper back surface portion can be obtained without processing the head portion of the screw 27. 24 does not protrude.
In addition, since the sealing material 12 is filled in the gap 28 between the top plate 3 and the projecting portion 25 and the lower surface of the back guard 4 and the sub-gap 29 between the top plate 3 and the upper back surface portion 24, the watertight effect is further increased and Leakage can be reliably prevented.

In the top plate structure 14 of the sinks 1, 1 </ b> A, 1 </ b> B shown in the above-described embodiments and modifications, the sealing material 12 seals between the upper end of the back guard 4 and the upper ends of the frames 7, 16, 22. You may stop. Similarly, the gap between the upper end of the back guard 4 and a wall surface (not shown) may be sealed with a sealing material 12. With these configurations, water leakage from the upper part to the cabinet 2 and the wall surface can be prevented.
Moreover, this invention is not limited to the top plate structure 14 of the sink 1, It can employ | adopt also as various counters, a cooking stand, etc.
