Description

  The present invention relates to a kitchen counter formed by fixing a sink to an opening formed in a counter.

  The applicant of the present invention has attempted to manufacture a kitchen counter in which a sink is joined flat to an opening formed in a counter made of artificial marble or the like. This type of kitchen counter is formed by facing the inner peripheral edge of the opening and the folded piece formed on the flange portion of the sink through a gap and injecting an adhesive from the back side to fix them together. A part of the bonded portion where the adhesive is cured is exposed as a joint on the counter surface.

  In this way, if the flange pieces except the folded piece of the flange portion are joined with the surface exposed, and the counter and the flange portion (the flange piece) are joined to have almost the same height across the joint, The dirt on the surface is easy to see and clean, and the flat joint surface can be expected to improve drainage and aesthetics. Further, since the flange portion of the sink is provided with the folded piece so as to face the inner peripheral edge of the opening portion, the flange portion is strengthened and the bonding strength with the opening portion is improved.

By the way, the sink used for the kitchen counter is not limited to this type of flat junction, and when the bent piece such as the hook piece or the folded piece is formed, the bent portion (outer corner portion) In general, it is formed into a round shape from the viewpoint of aesthetics or damage prevention (see, for example, Patent Document 1). As for the opening of the counter, it is common to chamfer the upper end corner of the opening in a tapered shape to prevent deformation and damage (see, for example, Patent Document 2).
JP 2002-340403 A JP 2001-241080 A

  When using a sink having such a rounded part or a counter with a chamfered upper end corner of the opening for the above flat joint type, when trying to make the surface of the joint peripheral part completely flush, The joint width becomes wide by adding the width of the space between the inner peripheral edge of the opening and the folded piece to the rounded portion and the chamfered surface, and depending on the color and pattern of the joint, it may be too conspicuous and affect the beauty. is there.

  The present invention has been proposed in view of such circumstances. The purpose of the present invention is to prevent the joint exposed on the surface from becoming too wide in a kitchen counter in which the sink is fixed to the counter opening through the joint. The goal is to provide something with an aesthetic appeal.

  In order to achieve the above object, the kitchen counter according to claim 1 is a kitchen counter in which a flange portion of a sink is joined and fixed to an opening formed in the counter via a joint portion. , Provided with a flange piece arranged outside the opening of the sink and a folded piece extending substantially perpendicularly to the floor surface from the collar piece, the outer peripheral corner of the folded portion of the folded piece is formed in a round shape The joint is held in a state where the surface side of the counter and the flange is aligned at substantially the same height via a gap with the folded piece facing the inner peripheral edge of the opening. In the state, formed by injecting hard adhesive from the back side, the joint height formed by the hard adhesive injected into the gap was made substantially the same height as the lower end of the outer peripheral corner It is characterized by.

  The kitchen counter according to claim 2 is characterized in that a tapered chamfered surface is formed at the upper end corner of the opening, and the height of the joint is substantially the same as the lower end of the chamfered surface.

  The kitchen counter according to claim 3 is characterized in that the counter is made of artificial marble.

  In the kitchen counter of the present invention, the height of the joint formed between the counter and the hook piece is substantially the same as the lower end of the rounded part formed at the outer peripheral corner of the folded part of the folded piece, thereby Although there is a slight level difference, the joint width is almost the same as the gap width between the inner peripheral surface of the opening and the folded piece, and the width of the joint should be as narrow as possible as compared with matching the height of the joint to the upper end of the rounded portion. Therefore, the surface of the kitchen counter can be made more beautiful.

  In addition, in the kitchen counter with a chamfered surface at the upper corner of the counter opening, the joint height is also adjusted to the lower end of the chamfered surface, so the joint width is folded back to the inner peripheral surface of the opening. It can be made to substantially coincide with the gap width with the piece.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 2 is an external perspective view of a kitchen counter which is an example of the present invention.

  The kitchen counter 1 is formed of a counter (top plate) 2 made of artificial marble and a metal sink 3 fixed in alignment with an opening 21 formed in the counter 2.

  The counter 2 may be made of non-metal such as resin or metal, but it is desirable that the counter 2 is made of man-made or natural marble for the sake of beauty. In addition, the front edge of the counter 2 on the front side hangs down, a front sag part 2b is formed, the rear end rises, and an upright part 2a is formed.

  The sink 3 is formed by drawing, and a flange 31 for joining with the opening 21 of the counter 2 is provided around the entire periphery. A drain port 3a is provided in the recess, and a mounting table 3b such as a detergent is provided at the rear end. I have.

  On the counter surface, a part of the joint 3 (see FIG. 1) between the sink 3 attached to the opening 21 and the counter 2 appears as a joint 6 on the entire circumference of the sink 3. The joint 6 formed by the joint portion 5 is a hard, which will be described later, in which an inner peripheral edge 23 (see FIG. 1) of the opening portion 21 and a flange portion 31 extending outwardly around the entire periphery of the sink 3 are fixed. It forms a part of the joint 5 formed by curing the adhesive.

  3A is a plan view of the sink 3 including a joint portion with the counter 2, and FIG. 3B is a vertical sectional view taken along the line XX.

  The flange portion 31 of the sink 3 is formed over the entire circumference of the sink 3 and is attached and joined to the opening 21 of the counter 2 through the joint 6 over the entire circumference. As shown in FIG. 3 (b), the flange piece 31 and the joint 6 are exposed on the surface of the joint portion between the counter 2 and the sink 3.

  FIG. 1 is an enlarged longitudinal sectional view of the joining peripheral portion A of FIG. 3B, and shows the structure of the main part of the present invention.

  As shown in FIG. 1, the flange portion 31 has an inclined portion 34 and has an inclined shape that descends inward. From the horizontal portion 33 formed outward from the inclined portion 34, the flange portion 31 is formed on the floor surface. On the other hand, a folded piece 32 extending substantially vertically extends over the entire circumference. Further, the folded piece 32 is provided with through holes 35 at appropriate positions over the entire circumference.

  Since the flange portion 31 includes the inclined portion 34, the flange portion 31 has a structure that is strong against external force. Further, by providing the folded piece 32, the strength is further improved, and the flange portion 31 is wavy or distorted. And can maintain a stable shape. In particular, when handling the sink 3 such as during installation work, the flange portion 31 protruding in the horizontal direction is likely to come into contact with other objects. Can be reduced.

  Also, if the flange portion 31 is formed horizontally, the appearance and the flow of water will be very poor when the inner side of the flange portion is deformed so that it rises upward, but it will drop toward the inside of the sink 3. Since it has the inclined part 34 of a gradient, even if it deform | transforms a little, there is almost no such fear.

  Further, the outer peripheral corner portion 36 (hereinafter referred to as a rounded portion R) of the folded portion of the folded piece 32 is formed in a rounded shape, and the upper end of the rounded portion R (the height position of the horizontal portion 33) and the upper surface of the counter are substantially the same. The folded piece 32 of the flange 31 and the inner peripheral edge 23 of the counter opening 21 are opposed to each other so that the counter 2 and the sink 3 are fixed to each other with a hard adhesive filled from the back side. A part of the joint 5 where the adhesive is cured becomes the joint 6.

  The joint 6 has substantially the same height as the lower end RL of the rounded portion R and the lower end TL of the chamfered surface T formed at the upper end corner 24 of the counter opening 21. That is, as shown in the drawing, only the surface of the joint 6 has a slightly recessed shape. The degree of indentation is preferably about 0.1 to 1 mm in consideration of easy cleaning.

  The sink 3 is attached to the counter 2 by turning them over and aligning the surface side of the joint 5 so that they are flush with each other, and then injecting a hard adhesive from the back side.

  A hard adhesive is used that is produced in a liquid state by mixing a curing agent with a main agent composed of an epoxy resin, a urethane-based resin, etc., and is cured at room temperature after a predetermined time. Although one type of adhesive may be used, it is desirable to use two types as the surface side layer (first bonding layer) and the back side layer (second bonding layer). The first bonding layer agent that is injected first and appears as the joint 6 on the surface is excellent in aesthetics, does not change color, has high adhesive strength, and has a low viscosity that can be injected into the gap. The second bonding layer agent is preferably one having high adhesiveness, but may be a conventionally used low-cost one. In addition, the first and second bonding layer agents are components that solidify integrally during curing. In addition, although the state after hardening is typically shown in FIG. 1, the uniform interface as shown in figure is not formed by both bonding agents.

  The first bonding layer agent may be blended with a colorant (pigment, dye), a pattern material, or the like according to any color or pattern of the artificial marble or the stainless steel sink 3 used for the counter 2. By doing so, the joints 6 appearing on the surface are hardly conspicuous, and there is almost no possibility that the aesthetic appearance is impaired by the joints 6. As the pattern material, for example, a granular material having an average particle size of about 5 to 50 μm such as bengara color and black color used for artificial marble can be used.

  The filling of the first bonding layer agent is performed from the back side with a silicon rubber jig applied to the surface side of the counter 2 and the flange piece F with a gap therebetween. The shape of the silicon rubber jig will be described later with reference to FIG.

  The injected first bonding layer agent is also injected and filled into the gap formed between the inner peripheral edge 23 of the opening 21 and the folded piece 32, and is also filled into the through hole 35. One joint layer 51 is formed, and the joint 6 is formed so that the surface of the joint 6 is positioned at the lower end RL of the rounded portion R.

  The second bonding layer agent is injected without waiting for the curing of the first bonding layer agent, and is filled up to the position of the pier 4 firmly fixed to the lower surface of the opening edge portion 22 of the counter 2. 52 is formed.

  The crosspiece 4 is provided over substantially the entire circumference on the back side of the opening edge 22 and is firmly bonded to the hard adhesive. Moreover, the crosspiece 4 also has a function of a weir at the time of injecting the adhesive, and prevents the injected liquid adhesive from flowing out.

  In this way, the first and second hard adhesives are sequentially injected, filled, and cured to form the joint portion 5 including the two joint layers 51 and 52 that firmly connect the counter 2 and the sink 3. Then, on the surface of the joint portion 5, the upper end corner portion 24 of the opening portion 21, the joint 6 formed by the hard adhesive, and the flange portion 31 flange F are exposed on the surface.

  As described above, the joint peripheral portion of the counter surface is formed in a stepped state in which only the joint 6 is slightly depressed, but the joint width substantially coincides with the gap width between the opening inner peripheral surface 23 and the folded piece 32, Since the width can be reduced as much as possible, the joints 6 do not stand out, and the surface of the kitchen counter can be made to have a better aesthetic appearance.

  If the thickness of the sink 3 is 1 mm, the diameter of the rounded portion R depends on the thickness of the sink 3 and is about 1 mm at a minimum. When the gap width between the opening inner peripheral surface 23 and the folded piece 32 is 1 mm By adjusting the height of the joint 6 to the upper end of the rounded portion R, the joint width becomes 2 mm. On the other hand, if the height of the joint 6 is matched with the rounded portion R lower end RL, the joint width becomes 1 mm, and the difference is large. In particular, when the gap is further reduced, for example, when the gap is 0.5 mm, the radius of the rounded portion R is about 1 mm (because it depends only on the thickness of the sink 3). When adjusted to the upper end, it becomes 1.5 mm, and when adjusted to the lower end RL, it becomes 0.5 mm, and the effect of the configuration of the present invention is extremely great. In addition, the numerical value in this example does not consider the width of the chamfered surface T formed at the upper end corner 24 of the opening 21.

  Further, if the height of the joint 6 is set to the upper end of the rounded portion R and the upper end of the counter 2, a part of the surface of the joint 6 becomes a thin skin, so that the part is easily peeled off, and the thinned part is The aesthetics may be lost due to see-through, but according to the configuration of the present invention, there is no such fear.

  Of course, since the joint 6 which is a part of the joint portion 5 appears on the surface, it is easy to visually recognize dirt and accumulated water, and it can be wiped off immediately. Moreover, since the joint 6 is made of a hard adhesive, it does not penetrate to the inside even if mold occurs and can be easily removed.

  Moreover, since the flange part 31 is equipped with the folding | turning piece 32, an adhesive agent can get entangled with the folding | turning piece 32 and can implement | achieve joining with high adherability. Furthermore, it also enters into the through-hole 35 provided in the folded piece 32 and solidifies, thereby providing an anchor effect and strengthening the fixation.

  As described above, since the shape of the sink 3 is stabilized by the folded piece 32, the joint 6 formed between the opening 2 of the counter 2 can be formed at a uniform interval, and the joint 6 can be narrowed. In combination with this, the kitchen counter 1 can be made into a shape that is aesthetically pleasing.

  Note that the folded piece 32 provided in the flange portion 31 may be bent in a horizontal or tapered manner with its lower end outward. By doing so, the lower end part can be squeezed into the lower surface side of the counter 2, and a hard adhesive can fully be entangled and adhesiveness can be improved.

  Moreover, you may use a melamine decorative board as a material of the counter 2. FIG. Since the inner peripheral edge 23 of the opening 21 and the folded piece 32 are bonded to face each other, it is possible to conceal the mouth of the melamine decorative board. In addition, the adhesive strength can be enhanced by the mouth of the decorative board.

  FIG. 4 is a longitudinal sectional view of a main part of a kitchen counter which is another example of the present invention.

  In this example, a chamfered surface is not formed at the upper end corner 24 of the opening 21 of the counter 2, the height of the counter 2 is matched with the rounded portion R lower end RL of the flange 31, and the joint 6 has a similar height. It is trying to become the position. That is, in this example as well as the example of FIG. 1, the joint width is almost the same as the gap width between the inner peripheral surface 23 of the opening and the folded piece 32, and an excellent aesthetic appearance can be formed.

  In addition, since each part other than the counter 2 in FIG. 4 is the same as that of FIG. 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  FIG. 5 is a longitudinal sectional view showing an example of a silicon rubber jig for forming the joint 6 with a hard adhesive, and (a) and (b) show those corresponding to FIGS. 1 and 4, respectively. Yes.

  The silicon rubber jigs 10A and 10B have a frame shape that can be used by being applied to the joining peripheral part over the entire circumference of the opening 21, and can be used by being fitted into a fitting groove of a base (not shown) such as a plastic. desirable. The joining operation is performed by turning over the counter 2 and the sink 3 and placing them on the pedestal so that the peripheral portions of the joining are applied to the silicon rubber jigs 10A and 10B.

  A silicon rubber jig 10A shown in FIG. 5A includes a sink mounting portion 11 corresponding to the sink 3, a counter mounting portion 12 corresponding to the counter 2, and a height of the ground surface M to be formed between them. The joint forming portion 13 is formed to be higher by about 0.1 to 1 mm in accordance with the height, and the joint forming portion 13 includes the round corresponding portion 13 a corresponding to the round portion R of the flange portion 31 and the opening of the counter 2. The upper end corner portion 24 of the portion 21 is provided with a taper corresponding portion 13b corresponding to the chamfered surface T formed in a tapered shape.
