Description

  The present invention relates to a kitchen counter, and more particularly to a kitchen counter in which a sink is bonded and fixed to an opening formed in the counter via a joint.

A conventional kitchen counter is known in which a flange formed on the outer peripheral edge of the sink is polymerized from below on the back surface near the opening formed in the counter and attached using a jig such as an adhesive or a bolt. It has been.
In such a mounting structure, a gap or a step is formed at the joint between the lower end of the inner peripheral edge of the opening of the counter and the upper end of the inner peripheral edge of the sink flange, or the sealant is exposed. In addition, dirt easily adheres to the step and the sealing agent, and since they are formed on the side peripheral surface, cleaning is not easy.

For example, in Patent Document 1, such a mounting structure is not used, and a sink mounting hole is opened in the core material of the top plate in which a melamine decorative plate is attached and integrated on the surface of a wooden core material, and the decorative plate is provided. The through hole having a smaller diameter than the mounting hole is formed to project the engaging piece portion, and on the other hand, the engaging piece portion of the decorative plate is formed on the upper surface of the upper flange of the synthetic resin thick molding sink. A step portion having the same diameter as the through hole and a depth corresponding to the plate thickness of the decorative plate is formed, and the engaging piece portion of the decorative plate is fitted and bonded to the step portion of the sink so as to be flush with each other. A structure has been proposed in which the core member and the sink are joined with a foam to attach the top plate and the sink.
In this case, since the engagement piece of the decorative plate is placed on the upper surface of the flange of the sink and is flush with the surface of the sink, matching the color of the sink with the color of the surface of the decorative plate makes it possible to achieve a sense of unity between the top plate and the sink. It is said that.

Moreover, in patent document 2, while forming a flange part toward the outer side at the upper-end periphery of a sink and forming a protrusion part 1-2 mm in height toward the downward direction from the outer periphery of this flange part, the upper end of a sink is formed. In the vicinity of the portion, a taper portion is formed so as to incline toward the center of the sink as it goes downward. On the upper surface around the opening edge of the counter made of artificial marble, the flange is more than the other portion of the counter. Forming a flange mounting portion on which the flange portion divided by the thickness of the portion is mounted, and further forming an escape portion on the outer peripheral edge of the flange mounting portion for allowing the protrusion to escape ing. In addition, the pedestal fixed to the lower peripheral surface of the opening edge of the counter is inclined such that the inclination angle is slightly larger than the taper portion, and the inclination is inclined toward the inner side of the opening toward the side of the opening side. A surface portion is formed.
The counter having the above-described configuration is attached to the sink by bringing the lower surface of the flange portion into contact with the flange mounting portion, the projecting portion is disposed in the escape portion, and the inclined surface portion of the crosspiece. The splint is fixed to the lower surface of the counter so as to be pressed along the taper portion of the sink, and the protrusion is filled with a caulking material so that the upper surface of the flange portion and the upper surface of the counter adjacent thereto are surfaces. It is done to be one.
In this case, since the counter and the sink are joined by the small amount of the caulking material to the escape portion and the protrusion being hooked on the escape portion, the sink can be easily detached from the counter, Since the tapered portion is in pressure contact with the inclined surface portion of the pier, the weight of the sink is distributed and received, and the sink can be attached to the counter with good stability.
JP-A-3-5779 (see FIG. 1) JP 2002-348932 A (see FIG. 1)

In the mounting structure of the counter (top plate) and the sink as in Patent Documents 1 and 2, the flange formed on the outer peripheral edge of the sink on the back surface in the vicinity of the opening formed in the conventional counter as described above. Unlike the case where the part is polymerized from below and attached using an adhesive or a jig such as a bolt, the flange part formed on the outer periphery of the sink is exposed on the surface side, so the exposed flange part is formed smoothly Thus, it is preferable to have excellent design properties.
In this regard, in the mounting structure of the top plate and the sink described in Patent Document 1, it is said that a sense of unity between the top plate and the sink can be achieved, but the step portion of the flange portion of the sink and the engagement piece of the decorative plate It is necessary to form the part with the same diameter and the same thickness over the entire circumference. Especially, it is made of stainless steel, and the surface side of the flange part of the sink that is prone to undulation, deformation, etc. is smoothed to enhance the design. For this purpose, the joining process takes much time.

Even the one described in Patent Document 2 requires that the thickness of the flange mounting portion and the flange portion be substantially the same, and the joining process takes much time as described above.
Also, since the counter and the sink are joined by minute protrusions and relief parts, and a caulking material that joins them, the bonding area of the caulking material is small, and the flange portion of the sink due to aging deterioration of the caulking material and the sink, etc. There was a risk of floating in the vicinity and loss of the smoothness of the flange portion.
Further, since the escape portion, that is, the joint portion between the counter and the flange portion of the sink is formed on the surface side, it can be easily cleaned. However, it has been frequently used for the joint portion between the counter and the sink. The caulking materials used are soft agents such as silicon sealant and butyl rubber, and when mold occurs at the joint, mold may penetrate into the inner layer, not just the surface layer, due to the roughness of its molecular structure. There was a risk that it would be difficult to remove mold.

A substantially rectangular shape with rounded corners is formed, and an opening 13 in which the sink 20 is disposed is opened. The opening 13 is formed to have a slightly larger diameter than the outer peripheral edge of the flange portion 22 of the sink 20, and a minimum gap is required due to molding errors and expansion / contraction and deformation of the counter 10 and the sink 20 after molding. It is formed between the inner peripheral edge 15 of the portion 13 and the folded piece 25.

A pressing member 50 is interposed on the back surface of the flange portion 22 described later between the folded piece 25 and the side wall 26 of the sink 20. In this embodiment, as shown in the drawing, the folded piece 25 and the sink 20 From the side wall 26, gaps G <b> 1 and G <b> 2 into which a hard adhesive described later is injected are interposed.
The pressing member 50 is formed of a synthetic resin, metal, wood, or the like into a substantially prismatic or cylindrical shape, with one end 51 in contact with the back surface of the flange portion 22 and the other end 52 injected with a hard adhesive. In this way, the height is such that it is exposed from the joint 30 formed.
In the present embodiment, a plurality of the pressing members 50 are interposed at intervals along the circumferential direction of the horizontal portion back surface 24b of the flange portion 22, and three front side pressures are provided on the front side of the horizontal portion back surface 24b. The clamping member 50a is provided with three rear pressure members 50b on the rear side, two left pressure members 50c on the left side, and two right pressure members 50d on the right side.

A drain port 21a is formed at the center rear side of the bottom surface 21 of the sink 20, and an upper portion is opened. A flange portion 22 extending outward is formed at the upper peripheral edge of the opening. .
The flange portion 22 has a taper portion 23, a horizontal portion 24, and a folded piece 25. The taper portion 23 is slightly inclined inward, and the horizontal portion 24 has an outer periphery than the taper portion 23. Around the outer periphery of the horizontal portion 24, a folded piece 25 that extends substantially perpendicularly to the floor is provided. In the folded piece 25, holding holes 25b are opened at a plurality of positions at intervals over the entire circumference.
Further, a crosspiece 40 is provided around the back surface 16 near the opening 13 of the counter 10. The crosspiece 40 is formed in a cross-sectional rectangular shape with wood or synthetic resin such as plywood, particle board, square wood, etc., and is fixed to the back surface 16 over the entire circumference at a certain distance from the inner peripheral edge 15 of the opening 13. Yes.

The counter 10 and the sink 20 are bonded and fixed via a bonding portion 30. The bonding portion 30 is attached to the surface side 14 of the counter 10 and the surface side 24 a of the horizontal portion 24 of the flange portion 22 serving as the upper end portion of the sink 20. It consists of a first bonding layer 31 positioned and a second bonding layer 32 positioned on the back side thereof.
Further, the joining portion 30 holds the inner peripheral edge 15 of the opening 13 and the folded piece 25 facing each other, and holds the surface sides 14 and 24a of the counter 10 and the sink 20 in a state of being aligned through a gap. In this state, the back surface of the counter 10 and the sink 20 is interposed on the back surface of the flange portion 22 between the folded piece 25 and the side wall 26 of the sink 20 with a pressing member 50 for pressing the flange portion 22 from the back side to the front side. It is formed by injecting a first hard adhesive forming the first bonding layer 31 and a second hard adhesive forming the second bonding layer 32 from the side, and a part of the first bonding layer 31 is a joint J It is set as the structure exposed to the surface side of the said clearance gap so that it may form.
Furthermore, in this embodiment, the surface sides 14 and 24a of the counter 10 and the sink 20 are formed so as to be substantially flush with the joint J interposed therebetween.

Specifically, as shown in FIG. 4, the counter 10 is placed upside down on the upper surface 60 a of the base 60 on which the silicon rubber jig 61 formed in an annular shape corresponding to the joint J is disposed. The sink 20 is turned upside down in the opening 13 and placed on the upper surface 60 a of the pedestal 60 so that the silicon rubber jig 61 is elastically contacted or brought into contact with the joint corresponding to the joint J.
At this time, the gap between the inner peripheral edge 15 of the opening 13 of the counter 10 and the outer peripheral surface 25a of the folded piece 25 of the flange portion 22 of the sink 20 is made substantially uniform over the entire circumference, and the surface of the counter 10 Positioning is performed so that the side 14 and the surface side 24a of the horizontal portion 24 of the sink 20 are substantially flush with each other, with respect to the base 60 and the silicon rubber jig 61 (see FIG. 4). The counter 10 and the sink 20 are pressed and pressed from each other.
The gap is preferably about 0.5 mm to 5.0 mm from the viewpoint of design and absorption of molding errors and the like, and more preferably around 2.0 mm. The design strength is excellent without impairing the bonding strength between the sink 20 and the sink 20.

Further, at this time, one end 51 of each pressing member 50 is brought into contact with the predetermined portion of the horizontal portion back surface 24b of the flange portion 22, and the other end 52 of each pressing member 50 is moved downward from above (FIG. 4). The horizontal portion 24 of the flange portion 22 is pressed against the pedestal 60 by pressing uniformly toward the white arrow Z direction in FIG.
As a result, when the sink 20 is placed on the pedestal 60, height difference or distortion occurs on the surface side 24 a of the horizontal portion 24 of the flange portion 22, or the surface side of the horizontal portion 24 of the pedestal 60 and the flange portion 22. Even when a gap or the like is generated between the front surface 24a and the front surface 24a, the front surface 24a can be held in a flat shape. In particular, as in the present embodiment, a plurality of pressing members 50 are disposed on the horizontal portion back surface 24b at intervals along the circumferential direction, and the other end 52 is uniformly pressed to form the flange portion 22. Since the horizontal portion 24 is pressed against the pedestal 60, for example, compared to the case where the horizontal portion 24 is provided over the entire circumference or substantially the entire circumference of the horizontal portion back surface 24b, the bonding strength between the counter and the sink is increased. It can be easily made into a flat shape without hindering.

As described above, the counter 10 and the sink 20 are positioned on the upper surface 60a of the pedestal 60, and a hard adhesive is injected from the back side of each pressing member 50 while being pressed (see FIG. 1 below). .
As the hard adhesive, for example, an adhesive composed of a two-component room temperature curable resin composition composed of a mixture of a main agent and a curing agent is suitable. As the main agent, an epoxy resin type or a urethane resin type, Examples of the curing agent include polyamide and isocyanate based on the main agent.
Such a two-component room temperature curable adhesive becomes hard when the curing reaction proceeds and is completely cured. Thereby, the surface side 24a of the flange part 22 hold | maintained in the flat shape by each pressing member 50 as mentioned above can be made into a flat shape.

At this time, in this embodiment, two types of hard adhesives are used.
That is, as the hard adhesive, the first hard adhesive that forms the first bonding layer 31 and the second hard adhesive that forms the second bonding layer 32 are used, and the first hard adhesive is the second hard adhesive. It has a lower viscosity than the adhesive.
In the present embodiment, a low-viscosity epoxy resin two-component room temperature curing adhesive is used as the first hard adhesive, and the second hard adhesive has a viscosity higher than that of the first hard adhesive. A high-viscosity urethane resin-based two-component room temperature curable adhesive is applied, but is not limited to this, the first hard adhesive is a urethane resin system, the second hard adhesive is an epoxy resin system, or Any of them may be epoxy resin-based, or all may be urethane resin-based.
As the epoxy resin, a bisphenol A-type epoxy resin, an epoxy resin modified like a urethane-modified epoxy resin, or the like may be used.
Further, as the urethane resin, urethane resin such as non-yellowing or non-yellowing type may be used. According to this, the weather resistance and light resistance are excellent.

In the state where the counter 10 and the sink 20 are aligned as described above, the first hard adhesive is injected first. Since the first hard adhesive has a low viscosity as described above, the first hard adhesive is folded between the inner peripheral edge 15 of the opening 13 of the counter 10 and the outer peripheral surface 25a of the folded piece 25 of the sink 20, or the folded of the sink 20. The gap formed between the inner peripheral surface 25c of the piece 25 and the side wall outer peripheral surface 26a of the sink 20, the holding hole 25b provided in the folded piece 25, the inner peripheral surface 25c of the folded piece 25, and the outer peripheral surface of the side wall of the sink 20 The gaps G1 and G2 formed between 26a and each pressing member 50 are also filled without gaps and without generating bubbles or the like due to their low viscosity. In addition, on the surface side, the above-described silicon rubber jig 61 does not form “overhang”, “overhang” or the like of the first hard adhesive, and the joints J are formed substantially uniformly.
In addition, it is preferable to inject | pour the said 1st hard adhesive to the quantity which the one part contacts the side surface 41 by the side of the sink of the crosspiece 40 like the example of a figure. Thereby, as described later, the bonding strength between the counter 10 and the sink 20 can be increased.

Next, before the first hard adhesive is cured, the second hard adhesive is injected from the top of the first hard adhesive to the vicinity of the upper end of the crosspiece 40 (pointing to the upper end in the state shown in FIG. 4). To do.
According to this, even when the first hard adhesive is injected into the gaps and voids as described above and the curing time is long due to the low viscosity, the heat generated by the second hard adhesive is hardened. 1 Hardening reaction of hard adhesive can be helped and cured faster.
Further, the second hard adhesive is made cheaper than the first hard adhesive, and the second hard adhesive is injected more than the first hard adhesive, as shown in the figure, so that the counter 10 and the sink 20 can be manufactured at low cost without impeding the bonding strength.

When each hard adhesive is sufficiently cured in the above-described state, the first bonding layer 31 and the second bonding layer 32 are formed, and then the bonded counter 10 and the sink 20 are detached from the upper surface 60a of the base 60. Then, the surface sides 14 and 24a of the counter 10 and the sink 20 are formed to be substantially flush with the joint J, that is, a part of the first bonding layer 31 exposed on the surface side.
In FIG. 1 and FIGS. 5 and 6 to be described later, a boundary surface between the first bonding layers 31, 31A, 31B and the second bonding layer 32 is formed. In fact, as the curing reaction proceeds, it goes without saying that the first hard adhesive and the second hard adhesive are cured in the vicinity of the boundary surface in a mixed state.
Moreover, in this embodiment, although two types of 1st hard adhesives and 2nd hard adhesives are used as a hard adhesive which forms the junction part 30, 1 type of hard adhesives are used. Alternatively, the bonding portion 30 may be formed.

Furthermore, the shape of the pressing member 50 and the location and number of arrangement on the back surface 24b of the horizontal portion are not limited to those in the illustrated example, and can be appropriately selected according to the shape of the flange portion 22, etc. It is formed in an annular shape so that it can be pressed over the entire circumference along the circumferential direction of the horizontal portion back surface 24b, or according to the length of the straight line along the circumferential direction of each of the horizontal portion back surface 24b. It may be formed long. According to this, the smoothness of the surface side 24a of the horizontal portion 24 can be further enhanced.
Furthermore, after the counter 10 is placed on the upper surface 60a of the pedestal 60, as described above, the counter 10 is not pressed from above, but an air suction port (not shown) that opens to the pedestal 60 toward the counter 10 side. The counter 10 may be brought into close contact with the pedestal 60 by providing an air suction path (not shown) having the above and sucking by an air suction means (not shown). In this case, an annular groove is provided on the upper surface 60a of the pedestal 60 so as to surround the air suction port, and a sealing member (not shown) for sealing the groove such as rubber formed in an annular shape. ) Is preferably provided.

As described above, according to the kitchen counter A according to the present embodiment, the joint J that forms a part of the joint portion 30 between the counter 10 and the sink 20 is exposed on the surface sides 14 and 24 a of the counter 10 and the sink 20. As a result, dirt is easily visible and cleaning can be performed easily.
Further, since the counter 10 and the sink 20 are joined and fixed by injecting the hard adhesive, dirt is difficult to adhere to the joint J exposed on the surface side, the cleaning property is good, and mold is generated. However, since it becomes hard when cured as described above, it hardly penetrates into the inner layer and is easy to remove.
Further, since the folded piece 25 extending substantially perpendicular to the floor surface is provided around the flange portion 22 of the sink 20, the strength of the flange portion 22 is improved when the sink 20 is formed by drawing, Since deformation is less likely to occur and deformation after molding of the sink 20 can be reduced, the surface of the flange portion 22 (particularly the horizontal portion 24) can be made flat, and the width of the joint J can be made stable and substantially uniform. It can be. Further, the bonding strength between the counter 10 and the sink 20 is increased.

Furthermore, the joining part 30 makes the inner peripheral edge 15 of the opening part 13 and the folded piece 25 face each other, and in this state, the horizontal part 24 of the flange part 22 faces the horizontal part back surface 24b from the back side to the front side. Since it is formed by injecting the hard adhesive from the back side of the pressing member 50 for pressing, when the flange portion 22 is deformed after the sink 20 is molded, Also, the surface side 24a of the horizontal portion 24 can be flattened and joined to the counter 10.
In particular, as in the present embodiment, if two to three pressing members 50 are disposed on the front, rear, left, and right of the horizontal portion back surface 24b, the surface side 24a of the horizontal portion 24 extends along the circumferential direction. Can be easily held in a flat shape.
Further, in the present embodiment, the pressing member 50 is disposed with the gaps G1 and G2 into which the hard adhesive is injected from the folded piece 25 and the side wall 26 of the sink 20, so that the hard adhesive is provided. Can be sufficiently spread over the entire circumference without obstructing the flow path through which the liquid is injected.

Furthermore, by fixing the crosspiece 40 to the back surface 16 of the counter 10, when the first hard adhesive and the second hard adhesive are injected, the crosspiece 40 fixed to the back surface 16 of the counter 10 is dammed. The hard adhesive can be prevented from flowing out to other portions of the back surface 16 of the counter 10.
Furthermore, by fixing the crosspiece 40 to the back surface 16 of the counter 10, the counter 10 made of artificial marble as in the present embodiment can be joined with a hard adhesive without making the artificial marble thick. Therefore, a sufficient bonding strength can be obtained without impeding the bonding strength between the counter 10 and the sink 20. In this case, if the crosspiece 40 is made of wood as described above, each hard adhesive is bonded so as to be impregnated into the crosspiece 40, and the bonding strength between the counter 10 and the sink 20 can be further increased. .

In the present embodiment, the surface sides 14 and 24a of the counter 10 and the sink 20 are formed so as to be substantially flush with the joint J therebetween, so that there is almost no step between the counter 10 and the sink 20. It is not formed, and it becomes difficult for dirt to adhere to it, and the appearance is flat and has excellent design.
Furthermore, in the present embodiment, since the folding pieces 25 are provided with holding holes 25b at a plurality of locations at intervals over the entire circumference, the holding holes 25b are also filled with the hard adhesive, An anchor effect is exerted by the hard adhesive filled in 25b, and the bonding strength between the counter 10 and the sink 20 is further increased.
Furthermore, since the flange part 22 has the taper part 23 and the taper part 23 is made into the shape which inclined slightly inward, the water etc. which scattered around the sink 20 collect in the joint J vicinity. Therefore, it can be easily guided inward of the sink 20 and is easy to use. In addition, the formation of the tapered portion 23 improves the strength of the flange portion 22 as in the case of the folded piece 25 described above, so that the waviness and deformation are less likely to occur, and the deformation after molding of the sink 20 can be reduced. The surface can be made flat.

The mixing ratio of the resin agents for making the first hard adhesive have a low viscosity depends on the external environment such as temperature. The agent should have lower viscosity and higher quality than the second hard adhesive, that is, weather resistance, light resistance, heat resistance, water resistance, wear resistance, impact resistance, chemical resistance, etc. Is preferred.
Thereby, as compared with the conventional one in which the joint portion is not exposed to the surface side, the cleaning property is improved and the design property is also excellent.
Further, since the second hard adhesive is not exposed on the surface side, the second hard adhesive may be inexpensive in consideration of the adhesive strength and shrinkage rate with the first hard adhesive, the pier 40, and the sink 20.
As a result, it is possible to reduce the overall cost without disturbing the fixing force between the counter 10 and the sink 20.

Further, at least one of an antibacterial agent and an antifungal agent may be mixed in the first hard adhesive. As a result, the joint J exposed on the surface side is excellent in antibacterial and antifungal properties, and the second hard adhesive that is not exposed on the surface side does not need to be mixed, so the cost is low. Become.
Furthermore, a coloring agent (pigment, dye, etc.), a pattern material, or the like may be mixed with the first hard adhesive according to the color or pattern of either the counter 10 or the sink 20. Thereby, the joint J exposed on the surface side is not conspicuous, and the design is more excellent. Also in this case, as in this embodiment, in the configuration in which the joint portion is formed by two types of hard adhesives, the above-described colorant (pigment, dye, etc.), pattern material, etc. are exposed on the surface side. Since it only needs to be mixed with the first hard adhesive, the cost is reduced.

  In the present embodiment, artificial marble is applied as the counter 10 because of its high-quality appearance. However, the counter 10 is also applicable to a wooden counter in which a melamine decorative board is attached to a wooden board such as plywood or particle board. In this case, as described above, the counter and the sink are formed substantially flush with the joint between them, so that the end face (inner peripheral edge) of the opening of the wooden counter is not visible, and the end face is processed. In addition to being unnecessary, since the entire face of the mouth is covered with a hard adhesive, the face of the mouth is not exposed to water or moisture, and the counter is not expanded and deformed.

Further, in the present embodiment, the pressing member 50B has a width in the direction perpendicular to the circumferential direction of the horizontal portion back surface 24b of the flange portion 22 as in the second embodiment, as shown in the first embodiment. Unlike the voids of the second embodiment, a notch 54 is formed that forms a recess through which the hard adhesive can circulate.
The notch 54 is formed by notching the one end 51 side so that the circumferential side surface has a concave shape, and the recess side, that is, the one end 51 side is disposed in contact with the horizontal portion back surface 24b. ing.
According to this, the same effect as the second embodiment can be obtained, and since the concave portion is formed on the one end 51 side in contact with the horizontal portion back surface 24b, without obstructing the flow path of the hard adhesive, It becomes possible to spread the hard adhesive all over the circumference more smoothly.

Note that the notch 54 cuts off the one end 51 side that contacts the back surface 24b of the horizontal portion as in the present embodiment from the viewpoint of the strength of the pressing member 50B, the viewpoint of enabling smooth injection of each hard adhesive, and the like. However, the width of the pressing member 50B, the shape of the notch 54, and the like can be appropriately selected as in the second embodiment.
Further, in the second embodiment and the third embodiment, when the first hard adhesive forming the first bonding layers 31A and 31B is injected, the base 60 and silicon described with reference to FIG. 4 are used. Naturally, the rubber jig 61 is formed and arranged according to the height difference between the joints JA and JB, the counter 10 and the flange portion 22 of the sink 20.
Furthermore, the above-described height difference between the counter 10 and the flange portion 22 is preferably about 1 mm in both embodiments. According to this, in terms of appearance, it becomes substantially flat and has a flat shape, and is excellent in design.
