Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a washbasin mounting structure for fixing a washbasin to a washstand counter.

[Prior Art] Conventionally, as a structure for arranging a washbasin on a counter, the flange around the upper end of the washbasin is placed on the circumference of the mounting opening of the counter, and is further supported by a metal fitting provided on the underside of the counter. There is a frame type fixed structure.

As shown in FIG. 5, the washbasin 1 is inserted from above into the mounting opening 21 of the counter 20, and the lower surface of the flange 2 provided around the washbasin 1 is inserted into the mounting opening 21.
The washbasin 1 is placed on the opening edge surface of the counter 20, and the washbasin 1 is fixed to the counter 20 using the support metal fittings 3 and fixing bolts 22.

The upper end of the support fitting 3 is fixed to the lower surface of the counter 20 with screws 4, and the hole 5 at the lower end is fixed as shown in FIG.
A fixing bolt 22 is inserted through the fixing bolt 22, and a wing nut 23 is screwed onto the fixing bolt 22.

The fixing bolt 22 has a T shape with a flat head 24 at the upper end.
An elongated engagement hole 25 into which the head 24 can be inserted is provided in the lower surface of the washbasin 1 using a bolt.

The procedure for fixing the washbasin 1 using the support fitting 3, the fixing bolt 22, and the engagement hole 25 is as follows: First, the head 24 of the fixing bolt 22 is placed in a position that can be inserted into the engagement hole 25, and this head 24 is attached to the washbasin 1. Insert it from below. Next, by rotating the fixing bolt 22 approximately 90 degrees, the head 24 is engaged with the upper edge of the engagement hole 25, and the wing nut 23 is tightened.

As described above, the fixing bolt 22 applies an acting force in the direction of pulling down the washbasin 1, presses the flange 2 onto the counter 20 surface, and fixes the washbasin 1 in a fixed position.

[Problem that the invention attempts to solve]

Here, when inserting the fixing bolt 22 into the washbasin 1, since the head 24 of the fixing bolt 22 and the engagement hole 25 have directionality, it is necessary to align them.

In this case, since the fixing bolt 22 is installed by an operator in a narrow cabinet, such positioning of the fixing bolt 22 is extremely troublesome, which is not preferable in terms of workability.

Furthermore, from the perspective of the structure of the washbasin 1 itself, depending on the shape of the product, the opening area of the engagement hole 25 may not be large, and the head 24 of the fixing bolt 22 may not be able to be inserted, which poses a problem in terms of versatility. There is.

The present invention was devised in view of the above-mentioned problems, and its purpose is to prevent the fixing bolt from attaching when installing the washbasin using the fixing bolt that is inserted and engaged with the engagement hole made in the support fitting and the bottom of the washbasin. To enable easy work without the need for positioning of the engagement hole and the engagement hole.

[Means and actions for solving problems]

In this invention, the flange of the washbasin is placed on the periphery of the mounting opening of the counter, and the upper end is engaged with the engagement hole provided on the bottom of the washbasin by inserting the support fitting fixed to the underside of the counter. In the mounting structure for a washbasin, which includes a bolt and a nut that is threaded onto the fixing bolt and engages with the lower surface of the support fitting, the upper end of the fixing bolt is an engagement part bent into a substantially J-shape. At the same time, the opening cross section of the engagement hole is formed to be larger than the locus circle drawn by the tip of the engagement part around the fixing bolt axis,
Further, the opening edge of the engagement hole is provided with a rib for locking the engagement portion of the fixing bolt, so that the fixing bolt can be freely inserted into the engagement hole regardless of the orientation thereof.

〔Example〕

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

Fig. 1 is a partially cutaway front view of the washbasin 1 fixed to the counter 20, Fig. 2 is a partially cutaway side view of the same, Fig. 3 is a sectional view taken along the - line arrow in Fig. The figure is a perspective view of the washbasin 1, the support fittings 3, and the fixing bolts 6 viewed from below.

A pair of support fittings 3 are arranged on the left and right sides of the washbasin 1, as in the conventional example, and are attached to the counter 20 by screws 4.
It is fixed to a crosspiece 7 provided on the lower surface, and the lower end is bent into an L shape to form an insertion hole 5 for a fixing bolt 6. Incidentally, this insertion hole 5 is formed into a long hole shape so that the fixing bolt 6 can be moved in the left and right direction.

As shown in FIG. 3, the fixing bolt 6 has a thread 8 cut on the lower side and an engaging part 9 bent in a J-shape at the upper end.
are screwed together, and are also provided with a washer 11.

Furthermore, the washbasin 1 is provided with a flange 2 at a portion that comes into contact with the edge of the mounting opening 21 of the counter 20, and a recessed notch 13 is provided on the left and right sides of the bottom, and an engagement hole 14 is opened in this portion. There is. This engagement hole 14 has an inner diameter that allows the engagement part 9 of the fixing bolt 6 to be inserted therein,
Furthermore, as shown in FIG. 3, an annular rib 15 is provided on the edge of the opening that projects upward and is capable of locking the bent portion of the engaging portion 9.

In the above configuration, the procedure for installing the washbasin 1 on the counter 20 is the same as in the conventional example, and is carried out by first placing the flange 2 on the edge of the mounting opening 21, positioning it, and fixing it with the fixing bolts 6. .

The fixing bolt 6 and the washer 11 are inserted into the elongated insertion hole 5 of the support fitting 3 from below, and the engagement portion 9 at the upper end is inserted into the engagement hole 14. In this work of inserting the fixing bolt 6, by making the diameter of the engagement hole 14 larger than the engagement portion 9, the operator does not need to align the fixation bolt 6 and the engagement hole 14. . Therefore, even when working in a narrow cabinet, the fixing bolt 6 can be easily installed, and work efficiency can be improved.

After inserting the fixing bolt 6, when the wing nut 10 is screwed onto the screw 8 and tightened against the support fitting 3, the washbasin 1 is tilted downward due to the engagement between the engaging portion 9 and the rib 15. is pulled, and the flange 2 is placed on the counter 20.
Can be fixed by crimping it to the surface.

By providing such a rib 15 in the engagement hole 14, the strength can be sufficiently compensated for the acting force applied from the fixing bolt 6, so that the wing nut 10
The fastening force can be increased, and the washbasin 1 can be firmly fixed.

Here, it is clear that the shape of the opening of the engagement hole 14 is circular, which has an inner diameter that allows the engagement portion 9 of the fixing bolt 6 to be inserted therein, and has a minimum opening area. Therefore, if the engagement hole 14 is made circular, the restrictions on its placement position with respect to the bottom of the washbasin 1 will be relaxed, and the engagement hole 14 can be provided at the optimal position for each product. , the degree of freedom in design is also improved.

[Effect of idea]

This invention allows the washbasin to be easily installed without requiring alignment between the fixing bolt and the engagement hole, and also uses the increased strength provided by the ribs to firmly attach the washbasin to the counter. This has the effect of being able to be fixed in place.
