Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sink in which the sink is disposed below the counter.

[Conventional technology]

Conventionally, sinks for kitchen equipment include under-counter type sinks that are fixed to the underside of an artificial marble counter, and sinks that are formed integrally with the counter using a stainless steel plate.

Under-counter type sinks are manufactured in a factory and have a sink integrated into the counter, and those with large counters are generally able to be assembled on-site. In addition, after assembling this sink, it is normal to fix a front plate to the front of the cabinet to hide the sink, and even if the stainless steel plate counter and sink are integrated, the front plate is placed in the same way. ing.

[Problem that the invention attempts to solve]

The under-counter type was made in the 1980s.
As described in Publication No. 20706, the sink is fixed to the underside of the counter using a hanger. This hanger is fixed to the lower surface of the counter, supports opposite sides of the sink in the depth direction at multiple positions, and has a structure in which the flange surface of the sink is clamped and fixed to the lower surface of the counter.

By the way, if artificial marble or the like is used as the counter material, the strength of the front edge portion corresponding to the front side of the sink will be considerably reduced. This is because the depth dimension of the front edge portion is short and the wall thickness is thin due to the need to shorten the distance from the front side of the cabinet to the sink.

As described above, the strength of the front edge of the counter is low, so when the sink is supported by a hanger, the load is too large, which may cause the front edge to bend or deform. When this deflection occurs, not only does the fixation of the sink become unstable, but it also causes problems such as poor sealing between the sink and the counter, and water infiltration into the cabinet.

The present invention was devised in view of these problems, and aims to facilitate the attachment of a sink to a counter and prevent deformation of the front edge of the counter.

[Means for solving problems]

In order to achieve the above object, the present invention provides a sink in which an opening is provided in the counter attached to the upper end of the cabinet and a sink is placed directly below the opening, and a "shaped longitudinal section is formed on the inner wall of the left and right side panels of the cabinet. A pair of supporting metal fittings having a planar shape are fixed by running in the depth direction, and a reinforcing bar is attached between the upper surface of the supporting metal fittings and the lower surface of the counter, and the reinforcing bar is glued to the counter and fixed to the supporting metal fittings. The present invention is characterized in that a bolt is attached which is screwed into the supporting metal fitting and presses the lower surface of the flange of the sink in the counter direction, and an auxiliary metal fitting is further provided to draw the front edge of the counter to the flange of the sink.

〔Example〕

Hereinafter, the present invention will be specifically described based on embodiments shown in the drawings.

FIG. 1 is a front vertical sectional view of the sink according to the present invention;
FIG. 2 is a sectional view of essential parts showing the reinforcement structure of the front edge of the counter, and FIG. 3 is an exploded perspective view.

In the figure, the left and right side plates 2 of the cabinet 1,
A supporting metal fitting 4 using an angle having an L-shaped cross section is fixed to the inner wall of 3 with screws 5. The upper end of the bolt 6, which is inserted through and screwed into the horizontal part 4a of the support fitting 4, presses against the flange 9 of the sink 8 located at the lower part of the counter 7.

A reinforcing beam 11 is interposed between the horizontal portion 4a of the support fitting 4 and the counter 7. The reinforcing beam 11 has its upper surface fixed to the lower surface of the counter 7 with adhesive, and its lower portion is supported and fixed by the horizontal portion 4a of the support fitting 4 with screws 5a. These support fittings 4
And the reinforcing crosspiece 11 is connected to the side plate 2, as shown in FIG.
It has a long dimension in the depth direction of 3. Therefore, the horizontal portion 4a of the support fitting 4 is supported by the reinforcing crosspiece 11 over a wide area, and deformation of the horizontal portion 4a from bending up and down when tightening the bolt 6 is suppressed. Furthermore, if the reinforcing bar 11 is fixed to the lower surface of the counter 7 in advance, the positioning can be performed simply by touching the upper surface of the horizontal portion 4a to the lower surface of the reinforcing bar 11, so that the mounting of the support fitting 4 can be done easily and with high precision. I can do it.

The counter 7 forms an opening 10 that is slightly smaller than the upper end shape of the sink 8, and the sink 8 is set to match this opening 10. Then, by moving the bolt 6 upward from below the support fitting 4, the upper end of the bolt 6 pushes up and presses the flange 9 of the sink 8, thereby clamping and fixing the flange 9 to the lower surface of the counter 7. Note that a silicone seal (not shown) for waterproofing is provided between the upper surface of the flange 9 and the lower surface of the counter 7 that abuts the flange 9.

When fixing the sink 8 to the counter 7, the bolt 6 is screwed into the support metal fitting 4 to clamp the sink 8, but since the reinforcing bar 11 is attached, deformation of the horizontal portion 4a can be restricted. Therefore, the horizontal portion 4a of the support fitting 4 can always be maintained parallel to the flange 9 of the sink 8, and the pressing force in the axial direction of the bolt 6 can be reliably applied and firmly fixed.

By the way, as described above, the front edge 7a of the counter 7 has a reduced length in the depth direction in order to shorten the distance from the front side of the cabinet 1 to the sink 8, so that the front edge 7a of the counter 7 becomes weak in strength and easily deformed. To reinforce this, as shown in Figure 2, the counter 7
An auxiliary metal fitting 15 is arranged to attract the front edge 7a of the sink 8 to the flange 9 of the sink 8. This auxiliary metal fitting 15
is arranged approximately in the center of the front edge 7a, one end of which is engaged with the lower surface of the flange 9 of the sink 8, and the other end is connected to the front edge 7a with a screw 16.

Since the front edge 7a is drawn to the sink 8 by the auxiliary fitting 15 in this way, the lower surface of the front edge 7a is supported by the sink 8, and bending deformation can be prevented. That is, since the auxiliary fitting 15 restrains the front edge 7a to the flange 9 of the sink 8, this restraining force applies an acting force that integrates substantially the entire front edge 7a with the flange 9. Therefore, the front edge 7a is supported by the flange 9, and bending deformation etc. can be reliably prevented.

Further, by providing the reinforcing bar 11, deformation of the horizontal portion 4a of the support fitting 4 and the counter 7 is prevented, so that the flange 9 is reliably pressed by the bolt 6, and the counter 7 of the entire sink 8 is prevented from deforming. The fixation is also stable. Therefore, the drawing of the front edge 7a of the counter 7 toward the sink 8 side by the auxiliary metal fitting 15 is stabilized, and the flange 9 of the sink 8 is pulled toward the front edge 7a.
It can be applied firmly to the bottom surface of the Therefore, the reinforcing bar 11 not only prevents the support fitting 4 and the counter 7 from deforming, but also prevents the auxiliary fitting 1 from deforming.
5 to reliably attract the counter 7 to the sink 8 side, and it becomes possible to more effectively prevent deformation of the front edge 7a.

In addition, in the sink of the present invention, the sink 8 can be attached and detached from the front side of the cabinet 1. That is, insert the sink 8 from the front side of the cabinet 1,
It can be fixed by tightening the bolt 6, and when replacing it, the sink 8 can be easily replaced by loosening the bolt 6 and pulling out the sink 8 to the front. In this case, the front plate 20 that hides the sink 8 must also be attached to the cabinet 1 in a detachable manner.

[Effect of idea]

In the present invention, the deformation of the supporting metal fittings is suppressed by the reinforcing bars placed between the sink and the underside of the counter, and the sink can be reliably fixed to the counter by pressing the bolts. Furthermore, since the counter and the reinforcing agent are fixed with adhesive, the counter is prevented from lifting even if the bolts are strongly screwed in, and the counter is not deformed. In addition, when the counter is fixed in this way, the auxiliary metal fittings attract the front edge of the counter to the sink flange, improving the integrity between the counter and the sink, and the lining by the sink flange improves the integrity of the counter. Flexural deformation of the leading edge is prevented. Therefore, no gap is created between the bottom surface of the counter and the flange of the sink, and water intrusion into the cabinet due to poor sealing is prevented.
