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 can provide 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 with a height of 1-2 mm from the outer periphery of the flange part downward, On the peripheral upper surface of the opening edge of the molded counter, a flange mounting portion on which the flange portion is mounted is formed by being separated from the other portion of the counter by the thickness of the flange portion, An escape portion is formed on the outer peripheral edge of the flange placement portion to allow the protrusion to escape. The escape portion is filled with a caulking material, and the upper surface of the flange portion and the upper surface of the counter adjacent thereto are flush with each other. A structure for mounting the sink to the counter has been proposed.
In this case, since the counter and the sink are joined by a small amount of the caulking material to the escape portion and the protrusion being hooked on the escape portion, the removal of the sink from the counter is facilitated. ing.
JP-A-3-5779 (see FIG. 1) JP 2002-348932 A (see FIG. 1)

In the case where a part of the joint part between the counter (top plate) and the sink is exposed to the surface side as in Patent Documents 1 and 2, although the cleaning property is excellent, a part of the joint part is the surface. Since it is formed on the side, the exposed joint is preferably excellent in design.
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 sink and the engaging piece portion of the decorative plate are provided. It is necessary to form substantially the same diameter over the entire circumference and lose the gap between them, and considering the molding error and the expansion / contraction of each member after molding, the joining process is very laborious.

Moreover, in the thing of the said patent document 2, since the junction part of the flange part of a counter and a sink is formed in the surface side, although it can clean easily, in the junction part of a counter and a sink, Conventionally used caulking materials are soft agents such as silicon sealant and butyl rubber. When mold occurs at the joint, mold penetrates not only into the surface layer but also into the inner layer due to the roughness of its molecular structure. As a result, mold removal may be difficult.
In addition, it is necessary to form a flange mounting portion on the upper surface of the counter made of artificial marble, which may increase the processing cost.
Furthermore, since the counter and the sink are joined by minute protrusions and escape 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.
Furthermore, because of the structure, it is difficult to fill the caulking material from the back surface side, so the caulking material is filled from the front surface side, and advanced technology is required to improve the design of the front surface side.

According to the kitchen counter of claims 1 to 7, since the joint that forms a part of the joint between the counter and the sink is exposed on the surface side of the counter and the sink, dirt is easily visible, Easy cleaning.
In addition, since the counter and the sink are joined and fixed by injecting a hard adhesive, dirt is not easily attached to the joint exposed on the surface side, the cleaning property is good, and even if mold occurs. Since it is hard, it does not easily penetrate into the inner layer and is easy to remove.
Further, since the folded portion extending substantially perpendicular to the floor surface is provided around the flange portion of the sink, when the sink is formed, the strength of the flange portion is improved and undulation and deformation are less likely to occur. Thus, since the deformation of the sink after molding can be reduced, the surface of the flange portion can be made flat, and the width of the joint can be made stable and substantially uniform. Further, the bonding strength between the counter and the sink is increased.
Furthermore, the joint is formed by injecting a hard adhesive with the inner peripheral edge of the opening and the folded piece facing each other, with a positioning member interposed therebetween, and the counter and The width of the joint formed on the surface side with the sink can be easily adjusted, and the joining process can be facilitated.

Moreover, the front-rear direction indicated in the following embodiments will be described as a front side in the state where the user faces the kitchen counter as a front side, a rear side as a rear side, and a direction orthogonal to the front-rear direction as a left-right direction.

As shown in FIGS. 1 to 3, the kitchen counter A of the illustrated example includes an artificial marble counter 10 molded from a heat-resistant resin and a stainless steel sink 20 formed by drawing.
The counter 10 constitutes a top plate of the housing part (not shown), the front side edge of the counter 10 hangs down, the front sag part 11 is formed, the rear side edge rises, the back guard 12 is formed, and a flat surface is formed at the substantially center. 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, and the gap is formed so as to be larger in the front-rear direction than in the left-right direction.
That is, the difference between the width W1 in the front-rear direction of the outer peripheral edge of the sink 20 (the outer peripheral surface 25a of the folded piece 25) and the width W2 in the front-rear direction of the inner peripheral edge 15 of the opening 13 is 25 is larger than the difference between the lateral width W3 of the outer peripheral surface 25a) and the lateral width W4 of the inner peripheral edge of the opening 13, that is, (W2-W1)> (W4-W3). It is formed to become.

A positioning rib 17 constituting a positioning member protrudes from the inner peripheral edge 15 of the opening 13.
In this embodiment, the positioning rib 17 includes two front positioning ribs 17a provided on the inner peripheral edge 15 on the front side of the opening 13, two left positioning ribs 17b provided on the left side, and 2 provided on the right side. And right positioning ribs 17c.
A crosspiece 40 is provided around the back surface 16 in the vicinity of the opening 13. 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.

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 tapered portion 23 and is inclined slightly inward. A horizontal portion 24 is formed on the outer peripheral side of the tapered portion 23, and the floor surface is formed from the outer peripheral edge of the horizontal portion 24. On the other hand, a folded piece 25 extending substantially perpendicularly is provided. In the folded piece 25, holding holes 25b are opened at a plurality of positions at intervals over the entire circumference.

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 joint portion 30 makes the inner peripheral edge 15 of the opening portion 13 and the folded piece 25 face each other, and the positioning ribs 17 are interposed therebetween so that the surface sides 14 and 24a of the counter 10 and the sink 20 are separated from each other by a gap. In this state, the first hard adhesive forming the first bonding layer 31 and the second hard adhesive forming the second bonding layer 32 are injected from the back surface side. Thus, a part of the first bonding layer 31 is exposed to the surface side of the gap so as to form the joint J.
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, the counter 10 is placed upside down on a pedestal (not shown) provided with a silicon rubber jig (not shown) formed in an annular shape corresponding to the joint J, and an opening of the counter 10 is placed. 13, the sink 20 is turned upside down and placed on the pedestal so that the silicon rubber jig is elastically contacted with a portion corresponding to the joint J.
At this time, the clearance 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 provided on the inner peripheral edge 15 so as to be substantially uniform over the entire periphery. The positioning is performed by bringing the outer peripheral surface 25a of the folded piece 25 into contact with each positioning rib 17.

In this case, in the present embodiment, as described above, the gap is formed so as to be larger in the front-rear direction than in the left-right direction, so that the sink 20 is aligned with the front side edge of the inner peripheral edge 15 of the opening 13. Positioning is performed, and then positioning in the left-right direction is performed.
According to this, the sink 20 is positioned on the front side and bonded and fixed to the counter 10 without obstructing the action of the gap necessary for absorption of molding error, deformation after molding, etc. It is possible to make the joints J formed less conspicuous, that is, by making the width of the front joints J that are easily noticeable narrower than the width of the rear joints J that are difficult to stand out, it has excellent design characteristics And can.
Further, since two front positioning ribs 17a are provided on the front edge of the inner peripheral edge 15 at positions separated from each other as shown in the drawing, the front joint J can be easily made substantially the same width, It will be more excellent in design.

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.
In the left-right direction, the positioning ribs 17b and 17c are preferably in contact with the left and right edges of the inner peripheral edge 15 of the opening 13, respectively. If not, it is preferable to perform positioning so that the formed gap has the same width on both the left and right sides.

As described above, positioning is performed through the gap, and positioning is performed by aligning the surface side 14 of the counter 10 and the surface side 24a of the horizontal portion 24 of the sink 20 so as to be substantially flush with each other. Then, the counter 10 and the sink 20 are pressed and pressed against the pedestal and the silicon rubber jig from above (pointing to the top in an upside down state).
In this state, hard adhesive is injected between the counter 10 and the sink 20 from the back side thereof.
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.

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 clearance formed between the inner peripheral surface 25c of the piece 25 and the outer peripheral surface 26 of the side wall of the sink 20 and the holding hole 25b formed in the folded piece 25 also have no gaps due to its low viscosity, and bubbles or the like are generated. With the above-described silicon rubber jig, the first hard adhesive is not “over” or “extruded” on the surface side, 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 hardened, it is near the upper end portion of the crosspiece 40 from above the first hard adhesive (refers to the upper end in a vertically inverted state, and is different from the counter 10 on the sink side surface 41. The second hard adhesive is injected up to the vicinity of the side end).
According to this, even when the first hard adhesive is injected into the gap as described above and the curing time is long because of the low viscosity, the heat generated by the curing of the second hard adhesive is the first hard adhesive. Helps the curing reaction of the adhesive and can be 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 state described above, the first bonding layer 31 and the second bonding layer 32 are formed, and then the bonded and countered counter 10 and sink 20 are detached from the pedestal. 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 FIG. 4 to be described later, the boundary surfaces between the first bonding layers 31, 31A, 31B and the second bonding layer 32 are 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.
Further, the shape of each positioning rib 17 and the location and number of openings 13 formed on the inner peripheral edge 15 of the opening 13 are not limited to those shown in the figure, and may be provided on the rear side or provided only on the front side. .

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, since the joining portion 30 is formed by making the inner peripheral edge 15 of the opening portion 13 and the folded piece 25 face each other and interposing the positioning rib 17 therebetween, and injecting a hard adhesive, 10 and the sink 20 can be easily adjusted in the width of the joint J formed on the surface sides 14 and 24a of the sink 20 and the joining process can be facilitated. In particular, in this embodiment, the positioning rib 17 is opened as a positioning member. Since it forms in the inner periphery 15 of the part 13, a number of parts can be reduced and a joining process can be made easier.

Further, since the crosspiece 40 is fixed 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 parts of the back surface 16 of the counter 10.
Furthermore, by fixing the crosspiece 40 to the back surface 16 of the counter 10, even the counter 10 made of artificial marble as in the present embodiment is joined with a hard adhesive without making the artificial marble thick. Adhesive area increases, and 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. .

Furthermore, 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 a step between the counter 10 and the sink 20. Almost no dirt is formed, and dirt hardly adheres, and the appearance is flat and excellent in design.
Further, 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.
Further, since the flange portion 22 has a tapered portion 23 and has a slightly inclined shape inwardly, water or the like scattered around the sink 20 does not collect in the vicinity of the joint J, and the inside of the sink 20 Easy to navigate to and 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.

Next, another embodiment according to the present invention will be described with reference to the drawings.
4 (a) and 4 (b) are views similar to FIG. 1, showing a kitchen counter according to the second embodiment and the third embodiment, respectively.
The difference from the first embodiment is the configuration of the joint portion and the positioning member, and the other configurations are the same as those of the first embodiment, so the same reference numerals are given and the description is omitted.

In the second embodiment shown in FIG. 4A, the sink 20 is positioned slightly below the counter 10 and bonded and fixed thereto.
In other words, the counter 10 is arranged so that a slight difference in height is formed between the surface side 14 of the counter 10 and the surface side 24 a of the horizontal portion 24 of the flange portion 22 of the sink 20 so that the joint JA is slightly inclined toward the sink 20. Forming.
According to this, moisture adhering to the surface side 14 near the opening 13 of the counter 10 can be more easily guided to the inside of the sink 20, and the usability is improved.
In this embodiment, the positioning member is provided not on the counter 10 but on the sink 20 side.
That is, the positioning ribs 27 are projected from the outer peripheral surface 25a of the folded piece 25 at the same positions as the positioning ribs 17 described in the first embodiment.
According to this, like the first embodiment, the number of parts can be reduced, and the joining process can be further facilitated.
The positioning of the counter 10 and the sink 20 in the present embodiment before the hard adhesive is injected is the same as in the first embodiment, and a description thereof will be omitted.

On the other hand, in the third embodiment shown in FIG. 4B, the sink 20 is positioned and slightly above the counter 10, and they are bonded and fixed.
That is, the counter 10 is arranged so that there is a slight difference in height between the surface side 14 of the counter 10 and the surface side 24 a of the horizontal portion 24 of the flange portion 22 of the sink 20, and the joint JB is the inner peripheral edge 15 of the opening portion 13 of the counter 10. It forms so that it may become horizontal toward the R end of the corner | angular R of the folding piece 25 of the sink 20 from an upper end.
According to this, the width of the joint JB can be formed slightly narrower than the joint J described in the first embodiment, the joint JB is not conspicuous, and the design is more excellent.
In the present embodiment, the positioning member is not provided in either the counter 10 or the sink 20, but is configured to be embedded in the joint 30B as a spacer 37 configured as a separate member.

In this way, by configuring the positioning member as a separate member, the width of the front and rear, left and right gaps formed between the plurality of types of spacers 37, that is, the inner peripheral edge 15 of the opening 13 and the folded piece 25, is increased. Accordingly, a plurality of types of spacers 37 can be prepared, the width of the joints JB formed on the surface sides 14 and 24a of the counter 10 and the sink 20 can be easily adjusted, and the joining process can be facilitated.
In this case, after the counter 10 and the sink 20 described above in the first embodiment are arranged on the pedestal, a spacer 37 is inserted into the gap formed on the front side in the same place as in the first embodiment. In addition, positioning may be performed by inserting the spacers 37 into the gaps formed on the left and right sides so that the widths of the gaps formed on the left and right sides are substantially the same.
According to this, even if a molding error or deformation after molding occurs in the counter 10 or the sink 20 as described above, the width of the joint JB can be easily made substantially the same in the front, rear, left and right. The counter 10 and the sink 20 can be bonded and fixed to each other, and the design is excellent.

In the second embodiment and the third embodiment, when the first hard adhesive forming the first bonding layers 31A and 31B is injected, the pedestal and the silicon rubber jig are bonded to the joints JA and JB. Of course, it is formed and arranged in accordance with the height difference of the flange portion 22 of the counter 10 and the sink 20.
Further, the 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.
Further, in the third embodiment, when the spacer 37 is inserted into the gap, an adhesive is applied to the spacer 37 so that the spacer 37 is not exposed on the surface side of the counter 10 and the sink 20. It is preferable to perform positioning as described above by adhering to either the inner peripheral edge 15 or the outer peripheral surface 25a of the folded piece 25.
