Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a counter for kitchens, such as a sink, which has a sink integrated into its lower surface, or a counter, such as a bathroom vanity, which incorporates a washbasin.

[Conventional technology]

2. Description of the Related Art Conventionally, for example, in system kitchens, counters used for cooking and working, including sinks, have been integrated into a cabinet. This counter is fixed to the upper surface of a cabinet placed on the floor using metal fittings or the like, and post-form counters made of wood are generally popular.

In recent years, instead of this post-form counter, stone has been used to give a sense of luxury, especially in system kitchens where the kitchen is designed to include the entire kitchen. As this stone material, natural stones such as granite, artificial marble, etc. that can be manufactured at relatively low cost are used.

[Problem that the invention attempts to solve]

By the way, a kitchen sink needs to be equipped with a sink for washing dishes, and for a stone counter, this sink is placed on the underside of the counter. One purpose of this is to prevent dissimilar materials from being exposed on the counter surface.

FIG. 4 shows a sink 51 for a counter 50.
It is a schematic diagram showing the arrangement of. A sink hole 52 having an opening area slightly smaller than the outer peripheral surface of the upper end of the sink 51 is formed in the counter 50, and the sink 51 is connected and fixed to the lower surface of the counter 50 along this sink hole 52.

However, in order to provide the sink hole 52, the front side portion 53 of the counter 50 has an extremely small depth compared to other portions. Further, as shown in the figure, when the sink hole 52 is provided at the end of the counter 50, the dimension of the end portion 54 in the frontage direction is also shortened.

On the other hand, when stone is used as the material for the counter 50, its mechanical strength against compression, tension, and especially bending is low. Furthermore, natural stones such as granite or stone materials such as artificial marble are much more brittle and break easily than wood.

In this way, when stone is chosen as the material,
The front side portion 53 and end portion 54, which have smaller depth and width dimensions than other portions, are more likely to break or crack. For this reason, if it is subjected to unexpected shocks during packaging or transportation at the factory, it may break and cannot be supplied as a product. In addition, during installation work on site, it is necessary to handle the product carefully so as not to cause any impact, so careful work is required, which also has the disadvantage of poor workability. Furthermore, even when the sink is used after installation, shocks are frequently applied to the front side portion 53 in particular, and cracks similarly occur, making it necessary to replace the entire sink. Also, a similar problem is
This problem also occurred on the counter of a bathroom vanity with a washbasin.

To solve this problem, cracking can be prevented by lining the underside of the counter with a reinforcing material to add strength. As this structure, for example, as described in Japanese Patent Application Laid-Open No. 58-58012,
One example is one that has a reinforcing bar integrated into the bottom of the counter. If such reinforcing bars are incorporated, the strength will be compensated even if the counter is made of stone.

However, the sink needs to be assembled so as not to interfere with these reinforcing bars, and the installation work becomes quite complicated. Furthermore, since the sink is directly fixed to the underside of the counter with screws passed through the batten, positioning the sink with respect to the sink hole becomes complicated, and there is a limit to the improvement in mounting accuracy.

As described above, the strength can be compensated by providing the reinforcing bars on the underside of the counter, but it is necessary to fix the reinforcing bars and the sink, and there are also problems with the accuracy of sink installation.

The problem to be solved with this invention is not only to reinforce the counter but also to enable the sink to be installed easily and with high precision.

[Means to solve the problem]

The present invention is a counter in which a counter is formed of natural stone such as granite or stone such as artificial marble, a sink hole is formed in the counter, and the sink is fixed to the underside of the counter in alignment with the sink hole. A reinforcing member with a rectangular cross section is arranged on the underside of the counter including the part along the sink hole, and anchor pins into which mounting bolts passed from under the reinforcing member are screwed are arranged so as to protrude downward from the underside of the counter, The anchor pin is fitted into a mounting hole provided on the surface of the reinforcing material that contacts the counter, and a sink mounting fitting for pressing the edge of the sink against the lower surface of the counter is connected to the reinforcing material.

〔Example〕

Hereinafter, the features of the present invention will be specifically explained with reference to embodiments shown in the drawings.

FIG. 1 is a bottom view of the counter 1 of this embodiment.

The counter 1 is made of natural stone such as granite or artificial marble, and is formed into a panel shape so that its upper and lower surfaces have high flatness. In a position biased to the left side, a sink hole 2 is formed in a rectangular shape with circular arc corners at its four corners.

Further, a reinforcing member 3 is fixed to the lower surface of the counter 1. The reinforcing material 3 includes one that runs in the frontage direction through the front and back edges of the sink hole 2, and one that runs in the depth direction along the left and right edges and right end of the sink hole 2. In other words, the arrangement is such that it surrounds the outer edge of the counter 1 and the entire periphery of the sink hole 2.

Figures 2 and 3 are - of Figure 1, respectively.
It is a longitudinal cross-sectional view when the sink 3 is fixed, being a line and a line arrow position.

The reinforcing member 3 is a hollow rectangular member with a square cross section made of steel, stainless steel, or the like. As shown in FIG. 1, the mounting holes 4 for the counter 1 and the sink mounting holes 5 are arranged alternately as appropriate.

As shown in FIG. 2, mounting holes 4 for fixing the reinforcing member 3 to the counter 1 are provided on both the upper and lower surfaces so as to pass through the reinforcing member 3 in the vertical direction. on the other hand,
The lower end of an anchor pin 6, which has a female thread formed in accordance with the pitch of the mounting hole 4, is embedded in the lower surface of the counter 1 so as to protrude from the lower surface of the counter 1. Then, by fitting the mounting hole 4 of the reinforcing member 3 into the protrusion 6a of the anchor pin 6 and positioning it, and screwing the mounting bolt 7 inserted into the mounting hole 4 into the anchor pin 6, the reinforcing member 3 is attached to the counter 1. Can be fixed integrally to the bottom surface.

The sink attachment hole 5 is provided in a portion of the reinforcing material 3 surrounding the sink hole 2. As shown in FIG. 3, this sink attachment hole 5 is opened only on the lower surface of the reinforcing member 3 having a rectangular cross section, and a spacer 8 is integrated with the lower surface by welding. A female thread 9 is formed in this spacer 8 so as to match with the sink attachment hole 5, and a sink attachment fitting 10 is fixed to this spacer 8 in place of the thin reinforcing member 3. The mounting bracket 10 is a combination of a flat support piece 11 and a support bolt 12, and the support piece 11 is fixed to the reinforcing member 3 by screwing the screw 13 into the female thread 9 of the spacer 8. In addition, a support bolt 1 is attached to the tip of the support piece 11.
2 vertically from below, and then tighten the support bolt 12.
The upper end of the sink 14 is brought into contact with the edge 15 portion of the sink 14.

With the mounting bracket 10 described above, the upper end of the support bolt 12 presses the edge 15 of the sink 14 against the lower surface of the counter 1, and this pressing force causes the sink to
4 is fixed to the bottom surface of the counter 1. Note that the edge 1 of the sink 14 is sealed against water.
A silicone sealant or the like is filled between the upper surface of 5 and the lower surface of counter 1.

In the above configuration, the counter 1 is supported by the reinforcing member 3 integrated with the lower surface of the counter 1.
Cracks and breakage are prevented when stone is used as the material for the counter 1. In other words, since the reinforcing material 3 is mainly placed close to the edge of the counter 1 and the opening edge of the sink hole 2, it is possible to reduce the load of external forces on stone, which is vulnerable to external forces such as compression, tension, bending, and impact forces. The reinforcing material 3 will receive it. Therefore, the load on the counter 1 is reduced, and as a result, it is possible to obtain a structure of the counter 1 that resists external forces, and cracks and breakage can be avoided.

Further, since the reinforcing member 3 is hollow, it is strong against tension and compression in the axial direction, and has sufficient resistance against bending in the vertical direction. Therefore, the counter 1 can be supported reliably, and at the same time, the counter 1 can be protected against external impacts.

Further, since the reinforcing material 3 has a rectangular cross section, one entire outer surface of the reinforcing material 3 comes into contact with the counter 1. Therefore, the pressure receiving area for the counter 1, which is given by the product of the arrangement length of the reinforcing material 3 and the width of one side in the cross-sectional direction, becomes large. For example, when a circular pipe is used as the reinforcing material 3, the contact with the counter 1 is a line contact in the axial direction, and the pressure receiving area is extremely small.

In this way, by increasing the pressure receiving area, even if a downward load is applied to the counter 1 on the right side centering on the anchor pin 6 in FIG. The degree of stress concentration is small. Therefore, when an external force is applied, the reinforcing material 3 effectively absorbs the load applied to the counter 1, and the counter 1 is prevented from breaking.

Furthermore, since the sink 14 is fixed to the counter 1 by the mounting bracket 10 using the reinforcing material 3, no separate structure for mounting the sink 14 is required. Therefore, not only the counter 1 can be reinforced, but the sink 14 can also be fixed at the same time, and the number of assembly steps is not increased. In addition, since the reinforcing member 3 is positioned by fitting the attachment hole 4 into the protrusion 6a of the anchor pin 6, if the anchor pin 6 is placed correctly, the reinforcing member 3 can be integrated into the counter 1 with precision. Ru. Since the sink 14 is held by the sink mounting bracket 10 connected to the reinforcing member 3, the mounting accuracy of the sink 14 itself is also improved.

In addition, in the embodiment, the reinforcing material 3 is arranged along the edge of the counter 1 and the opening edge of the sink hole 2, but it goes without saying that the reinforcing material 3 can be provided as appropriate in the parts where the load is applied. . Furthermore, the present invention can be applied not only to kitchen counters, but also to counters such as bathroom vanities.

[Effect of idea]

In the present invention, a reinforcing material is placed on the underside of the counter, so the counter can be reinforced against external forces such as compression, tension, and bending, thereby preventing cracking and breakage. In addition to increasing the strength of the counter, the reinforcing material is also used to attach the sink, making it easy to assemble the reinforcing material and sink. Since the reinforcing material is fixed by being fitted into the anchor pin provided on the counter, positioning can be performed at the same time, and the mounting accuracy of the sink, which is fixed not only by the reinforcing material but also by the mounting fittings connected to this reinforcing material, is improved.
