Description

[Detailed Description of the Invention] The present invention relates to a temporary fixing structure used when attaching a washbasin to a top plate.

When attaching a ceramic washbasin to a top plate of a washstand or the like via a metal frame, use a frame 3 as shown in FIG. 1 to temporarily attach the frame 3 and washbasin 2. This is well known.

The frame 3 used for this temporary attachment has the annular standing wall 3c at several places around the entire circumference of the frame 3.
A notch 5 is provided in a U-shaped outline formed by two long sides along the circumferential direction and one short side. The method of temporarily attaching the washbasin 2 using this frame 3 is to place the washbasin 2 on the inner surface 3a' of the inner flange 3a of the frame 3, and then move it toward the outer peripheral surface 2a of the washbasin 2.
The cutout portion 5 provided in the annular standing wall portion 3c is bent from the connecting short side 5a, and the upper peripheral edge portion 2b of the washbasin 2 is coupled and supported by the bent portion 6 and the inner flange portion 3a in a sandwich-like manner. It is something.

However, the washbasin 2, which is a ceramic product, generally does not have accurate external dimensions due to its nature, so the circumferential surface does not have a uniform curvature, and the thickness of the upper circumferential edge 2b also varies slightly. Therefore, the height from the inner flange inner surface 3a' of the frame 3 to the folding part 6 is:
Usually, it is set to the maximum value of the allowable wall thickness dimension width of the upper peripheral edge portion 2b. For this reason, in the temporary connection of most washbasins 2, the upper peripheral edge 2
A gap is created between b and the bent portion 6, and the washbasin 2 and frame 3 are left unfixed.

If you try to attach it to the top plate in this state, the washbasin 2 and the frame 3 may rub against each other during the work and cause damage, or when the washbasin 2 is turned over, the folding part 6 will strongly press against the upper peripheral edge 2b. There were cases where the upper peripheral edge portion 2b was damaged due to contact. Furthermore, the upper peripheral edge 2b
The rubbing between the inner flange portion 3a and the inner flange portion 3a also destroys the sealing material forming layer applied in advance between them.
This had drawbacks such as weakening the sealing effect.

The present invention was developed in view of the above-mentioned circumstances.
It is an object of the present invention to provide a novel temporary fixing structure for a washbasin that will not be damaged and will not destroy a sealing material forming layer.

The present invention will be described below based on drawings showing embodiments thereof.

In FIG. 2, a spacer 7 with a concave cross-section and a groove 8 into which the tip can be inserted is attached to several folded parts 6 provided around the entire circumference of the frame 3. There is. The spacer 7 has pressing surfaces 7a and 7b that are in close contact with the outer peripheral surface 2a of the washbasin 2 and the inner surface 3c' of the vertical wall portion of the frame 3, respectively. The spacer 7 is made of hard rubber, resin, wood,
In addition, it is made of a repulsive deformable material that deforms with an inherent repulsive force when strong pressure is applied.
Its external dimensions are such that the separation between the pressing surfaces 7a and 7b is slightly larger than the circumferential distance between the washbasin 2 and the frame 3.

Therefore, when the spacer 7 as described above is inserted into the space between the washbasin 2 and the frame 3, the pressing surface 7
a and 7b are compressed and brought into close contact with each other. As mentioned above, since the spacer 7 is made of a resilient deformable material, a regenerative reaction force acts within the elastic limit,
The washbasin 2 and the frame 3 are pressed and fixed.

The spacer 7 is attached so that the cutout part 6 provided on the frame body 3 is fitted in the groove part 8, and is pushed into the space between the washbasin 2 and the frame body 3. The washbasin 2, which has been appropriately pressed and biased around its entire circumference in this manner, is fixed to the frame 3 due to the reaction force of the back side of the washbasin against the pressing force. The number of spacers 7 to be installed is
Even if the number is not equivalent to , it is possible to fix the washbasin 2 and the frame 3 as long as there is one pair facing each other with the washbasin 2 in between.

FIG. 3 shows a different embodiment, in which the tip 6a of the folded portion 6 is bent again so as to follow the outer circumferential surface 2a of the washbasin 2. A conical ladder-shaped spacer 7 is screwed onto the tip 6a with a mounting screw 9, and the other side of the screwed portion is a pressing surface 7a that presses the outer peripheral surface 2a of the washbasin 2.
It is becoming. In this way, the shape and number of spacers can be changed as appropriate depending on the embodiment. Further, after the combination of the washbasin and the frame is stretched and fixed on the top plate, the spacer may be removed or left attached.

As is clear from the above explanation, according to the temporary fixing structure of the washbasin according to the present invention, since the washbasin and the frame are securely fixed, there is no possibility that the two may slip or wobble relative to each other. Never. Therefore, the upper peripheral edge of the washbasin will not be damaged or damaged during transportation and attachment to the top plate. Moreover, it goes without saying that the sealing material forming layer is not destroyed. Furthermore, in the past, when handling the combined washbasin and frame, it was necessary for two or more people to carefully work to prevent them from spinning or rattling. It has many advantages, such as being able to work easily even by one person and improving work efficiency since it does not spin idly.
