Description

  The present invention relates to a joining structure and joining method for a counter and a sink, and more particularly to a structure for integrally joining a counter and a sink installed in, for example, a kitchen or a washroom.

  Conventionally, there has been known a sink in which a stainless steel kitchen sink is integrally assembled with an opening of a counter made of artificial marble (see, for example, Patent Document 1).

  By the way, conventionally, as a method of integrally joining the counter and the sink, for example, as shown in FIGS. 5A and 5B, the counter 1 and the sink 2 are turned upside down so that the counter 1 and the sink 2 are turned upside down. The joining member 3 is thrown into the gap from above and joined. 8 in the figure is a reinforcing bar.

  In this conventional example, as shown in FIGS. 5A and 5B, there is an advantage that the joining member 3 does not appear on the product surface 6 side, but there is a step d at the joining portion between the counter 1 and the sink 2. Therefore, there is a problem that not only dirt is easily attached to the step d, but also cleaning is difficult to the depth of the step d.

  Therefore, in the course of reaching the present invention, the inventors have made the counter surface such that the outermost surface of the joining member 3 that joins the counter 1 and the sink 2 appears on the product surface 6 side as shown in FIGS. A joining method has been devised to improve the cleanability by joining 1 and the sink 2 with no step.

  That is, as shown in FIG. 6, the counter 1 and the sink 2 are turned upside down, and the lower surface of the gap between the counter 1 and the sink 2 is closed with the silicon rubber jig 10 to form the groove-like portion 7 opened upward, The joining member 3 is inserted from above the groove-like portion 7 to form the first adhesive layer 3A, and subsequently, the reinforcing second adhesive layer 3B is laminated. In this new bonding method, as shown in FIG. 7, the outermost surface of the first adhesive layer 3A appears on the product surface 6 side.

However, the joint part between the counter 1 and the sink 2 formed by the first adhesive layer 3A appearing on the product surface 6 side is one of the most noticeable parts by the user, and is important for determining the appearance of the counter 1 One of the elements. In other words, the new joining method that joins the counter 1 and the sink 2 without a step improves the cleanability, but deteriorates the good appearance due to the first adhesive layer 3A exposed to the outside. Has occurred.
JP 2006-291610 A

  The present invention has been made in view of the above-described conventional problems, and the object of the present invention is to make the joining member appearing on the product surface side inconspicuous and to maintain good appearance. It is possible to provide a counter-sink joint structure that can provide a sense of nature and luxury.

  In order to solve the above-described problem, in the invention according to claim 1, the sink 2 is assembled to the opening of the counter 1, and the opening end face 1a of the counter 1 and the flange 2a of the sink 2 are on the product surface 6 side. In the joining structure of the counter and the sink joined via the joining member 3 formed from the back side to the back side, the joining member 3 includes the first adhesive layer 3A located on the product surface 6 side and the first adhesive layer 3A. The first adhesive layer 3 </ b> A is formed in substantially the same color as the color of the counter 1.

  With this configuration, the joint portion between the counter 1 and the sink 2 can be made inconspicuous, and an appearance that eliminates the joint portion can be exhibited. It can be prevented from being damaged. In addition, only the first adhesive layer 3A needs to be colored.

  In the invention according to claim 2, in the invention according to claim 1, the joining member 3 is mainly composed of synthetic resin, and the first adhesive layer 3A is a handle for forming a handle or a pattern. The material 5 is blended with a synthetic resin, and the specific gravity of the pattern material 5 is slightly heavier than the specific gravity of the synthetic resin, so that the pattern material 5 is formed on the product surface 6 side of the joining member 3. It is characterized by this.

  With this configuration, in addition to the invention according to claim 1, when the counter 1 and the sink 2 are turned upside down and the synthetic resin is poured into the gap between the counter 1 and the sink 2 from above, The pattern material 5 blended with the synthetic resin is allowed to settle, and a pattern or pattern made of the pattern material 5 can be formed on the product surface side. That is, when the product is completed, not only can the same color as the counter 1 be formed, but also the pattern made of the pattern material 5 can be given to the joint portion between the counter 1 and the sink 2, so that the appearance of the joint portion can be further improved. 1 can be brought close to the appearance of 1, and a natural feeling and luxury can be obtained.

  Moreover, it is only necessary to blend the pattern material 5 only in the first adhesive layer 3A, and it is not necessary to blend the pattern material 5 in the second adhesive layer 3B, so the amount of the pattern material 5 can be saved.

  In addition, since the specific gravity of the pattern material 5 is only slightly heavier than the specific gravity of the synthetic resin forming the main body of the joining member 3, when the counter 1 and the sink 2 are joined, the pattern material 5 and the synthetic resin In the material tank used when mixing the handle material, the handle material 5 and the synthetic resin can be easily mixed together, and the handle material does not settle in a short time because it does not settle in a short time. . For this reason, workability is also improved.

  According to the present invention, it is possible to prevent the appearance from being damaged at the joint portion between the counter and the sink while reducing the amount of additives such as pattern materials and coloring agents, so that the counter and the cost can be reduced. The appearance of the sink can be kept good, and the product as a whole can have a natural feeling and luxury. That is, the product value of the product can be increased while saving costs.

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

  In FIG. 1, a stainless steel kitchen sink 2 (hereinafter abbreviated as “sink 2”) is assembled to an opening of a counter 1 made of artificial marble according to the present embodiment, and an opening end face 1 a of the counter 1 and a flange 2 a of the sink 2. And FIG. 2 shows an example of the joining process.

  The tip of the flange portion 2a of the sink 2 is a folded piece 2b that is folded inward in an approximately L shape. A gap between the folded piece 2b of the sink 2 and the opening end face 1a of the counter 1 is joined by a joining member, and the outermost surface of the joining member 3 appears on the product surface 6 side. Reference numeral 8 in FIG. 1 denotes a reinforcing bar that also serves as a part of the groove-like portion 7.

  As shown in FIG. 1, the bonding member includes adhesive layers 3 </ b> A and 3 </ b> B composed of a general-purpose bonding member 4 formed from the product surface 6 side toward the back surface side, and a general-purpose bonding member 4 for forming a handle or a pattern. It is comprised with the pattern material 5 mix | blended with.

  Here, the supply of the general-purpose joining member 4 is performed through a nozzle. As an example, an application device (not shown) including a syringe filled with the bonding member 3, a pressurizing unit that pressurizes the inside of the syringe, and a nozzle that discharges the bonding member 3 by pressurization is used.

  As the general-purpose joining member 4, an adhesive made of a low-cost synthetic resin that is not high-performance is selected. The general-purpose joining member 4 of this embodiment is colored in substantially the same color as the color of the counter 1 made of artificial marble. Furthermore, the general-purpose joining member 4 has a low viscosity. The type, color, etc. of the general-purpose joining member 4 can be selected and changed as appropriate.

  The pattern material 5 forms a pattern or a pattern, and the pattern material 5 for artificial marble is used as the pattern material 5. The specific gravity of the pattern material 5 is slightly higher than the specific gravity of the general-purpose joining member 4 (adhesive made of synthetic resin) (that is, substantially the same specific gravity) (in this embodiment, the general-purpose joining is used). The pattern material 5 having a specific gravity of 1.1 times or more and less than 1.2 times the specific gravity of the member 4 is used), and the particle diameter for forming the pattern material 5 is 0.6 mm or less. Are using things. The type, pattern, pattern, etc. of the pattern material 5 can be selected and changed as appropriate.

  Next, an example of a joining process will be described.

  First, as shown in FIG. 2, the counter 1 and the sink 2 are turned upside down, and the lower surface of the gap provided between the opening end surface 1a of the counter 1 and the folded piece 2b of the flange portion 2a of the sink 2 is elongated. The groove-like portion 7 opened to one side (upper side in FIG. 2) is formed by closing with a silicon rubber jig 10 having a shape and an inclined surface forming portion 10A. The general-purpose joining member 4 in which the pattern material 5 is blended is introduced from one side (the upper side in FIG. 2) of the groove-like portion 7 opened.

  The general-purpose joining member 4 first fills the material tank with the general-purpose joining member 4 and the handle material 5 and mixes the general-purpose joining member 4 and the handle material 5 in the material tank using a stirrer. At this time, since the specific gravity of the general-purpose joining member 4 and the pattern material 5 is substantially the same (specifically, the specific gravity of the pattern material 5 is slightly heavier), the general-purpose joining member 4 and the pattern material 5 are easily mixed. ing.

  Next, as shown in FIG. 3B, the general-purpose joining member 4 in which the pattern material 5 is blended is introduced from a nozzle to form a first adhesive layer 3A (for example, 8 mm), and the first adhesive layer. Before the 3A is cured, as shown in FIG. 3C, the general-purpose joining member 4 not mixed with the pattern material 5 is introduced from the nozzle from above the first adhesive layer 3A to reinforce the second adhesive layer. 3B (for example, 15 mm) is laminated and formed. Further, when the first adhesive layer 3A is formed, the general-purpose joining member 4 also enters the flange portion 2a through a communication hole (not shown) opened at an appropriate location of the flange portion 2a of the sink 2. The first adhesive layer 3A is formed from the groove-like portion 7 to the inside of the flange portion 2a.

  Here, the specific gravity of the pattern material 5 is slightly heavier than the specific gravity of the general-purpose joining member 4, and the general-purpose joining member 4 is a low-viscosity material, so it is blended in the first adhesive layer. The pattern material 5 tends to settle downward. In short, the pattern material 5 moves to the product surface side (the lower side when the counter 1 and the sink 2 are turned upside down) by its own weight, and thereby the product surface 6 side of the first adhesive layer that appears on the product surface 6. Then, an artificial marble pattern made of the pattern material 5 is formed.

  Then, after the general-purpose joining member 4 is cured, the product surface 6 is formed as shown in FIGS. 1 and 3A by removing the silicon rubber jig 10. Since the silicon rubber jig 10 is provided with the inclined surface forming portion 10A, the product surface 6 has a slight inclination with respect to the surface of the counter 1, and is in the same plane as the surface of the counter 1. It is not formed (that is, the surface of the counter 1 and the product surface 6 side of the first adhesive layer 3A are not flush with each other).

  In this way, the joint part between the counter 1 and the sink 2 can be the same color as the counter 1 made of artificial marble, and the pattern material 5 can have the same pattern and pattern as the artificial marble. Can be made inconspicuous, and an appearance as if the joint portion has been eliminated can be exhibited. That is, it is possible to suppress the deterioration of the appearance due to the joint portion between the counter 1 and the sink 2.

  By the way, as shown in FIG. 4, when the surface of the counter 1 and the product surface 6 side of the first adhesive layer 3A are flush with each other, the difference in color tone and pattern between the counter 1 and the first adhesive layer 3A is as follows. Even subtle differences will stand out. Therefore, in the present embodiment, the product surface 6 side of the first adhesive layer 3A is slightly inclined with respect to the surface of the counter 1, so that the appearance at the junction between the sink 2 and the counter 1 is as follows. Above, it can look like it is chamfered. By doing so, even if there is a slight difference in the color and pattern between the counter 1 and the general-purpose joining member 4, the angle formed by the surface of the counter 1 and the surface of the first adhesive layer 3A are formed. By making a difference in the angle, we dare to make the color sense of each surface different for the viewer of the product, and by making this part appear to be chamfered, It is difficult to give a sense of incongruity due to differences in patterns.

  Further, when the general-purpose joining member 4 in which the pattern material 5 is blended is introduced from the nozzle, the particle diameter of the pattern material 5 of this embodiment is 0.6 mm or less, so that it easily passes through the nozzle. And has the advantage that clogging is less likely to occur. Furthermore, when supplying the general-purpose joining member 4 (joining member 3) mixed with the pattern material 5 filled in the syringe constituting the coating apparatus to the groove-like portion 7, the specific gravity between the general-purpose joining member 4 and the pattern material 5 Since they are substantially the same, there is also an advantage that the pattern material 5 does not settle in the syringe for a short time of supply work.

  Furthermore, the effect of the present invention can be obtained only by coloring only the first adhesive layer 3A having an appearance and blending the pattern material 5. That is, in the second adhesive layer 3B, it does not appear on the product surface, so it is not necessary to have appearance and high quality. For this reason, the pattern material 5 is not blended in the second adhesive layer 3B in this embodiment. The quantity which uses the pattern material 5 as the whole product can be reduced. In addition, since the same inexpensive general-purpose joining member 4 as the conventional one can be used for the first adhesive layer 3A and the second adhesive layer 3B, an increase in cost can be suppressed.

  Moreover, it is preferable to add an antibacterial agent, a fungicide, etc. inside the 1st contact bonding layer 3A. In this case, an antibacterial agent or the like is added into the general-purpose joining member 4 forming the first adhesive layer 3A and introduced by a nozzle. This anti-bacterial agent or the like is used for the general-purpose joining member forming the first adhesive layer 3A. Since it is sufficient to add only in No. 4, there is an advantage that the amount of antibacterial agent, antifungal material and the like added thereto can also be reduced.

  Furthermore, by placing a heater inside the silicon rubber jig 10, the resin of the first adhesive layer 3A can be hardened quickly. That is, it is easy to be cured by the heat of the heater, the curing time is short, and the mold can be released quickly. As a result, the advantage that the mold release time of the silicon rubber jig 10 can be greatly shortened can be obtained.

  In the present embodiment, the first adhesive layer 3A and the second adhesive layer 3B are provided. However, the first adhesive layer 3A may be thick and the second adhesive layer 3B may not be provided.

It is a sectional side view of one embodiment of the present invention. It is a sectional side view which shows the state after joining of a counter and a sink same as the above. It is the schematic explaining the joining process same as the above, (a) shows the state after hardening of a joining member, (b) shows the state when the general purpose joining member and pattern material of a 1st contact bonding layer are thrown in (c) ) Shows a state when the general-purpose joining member of the second adhesive layer is introduced.
