[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching a callan to a sink or a sink.

[0002]

2. Description of the Related Art Heretofore, the applicant of the present application has previously filed Japanese Patent Application No. 4-54083 as a mounting structure of a callan for mounting a callan 1 while preventing rotation of a mounting surface 4 such as a counter. As shown in FIG. 3, the protrusion 3 serves as a detent engaging portion 3 on a part of the inner peripheral wall of a cylindrical mounting member 5 attached to a mounting hole 12 provided in the mounting surface 4.
The projection 3a and the cutout 2a as the engaging portion 2 formed by cutting out a part of the outer peripheral wall of the callan 1 are positioned on the mounting member 5 so as to be aligned. 1 is attached, and the curan 1 is attached so as to prevent rotation. Reference numeral 13 denotes a nut for mounting the mounting member 5 to the mounting surface 4.

[0003]

However, in the above-described conventional example, the mounting hole 12 provided in the mounting surface 4 is not provided.
The direction of the projection 3a is determined by the mounting direction of the mounting member 5 to the mounting member 5, and the direction of the callan 1 mounted on the mounting member 5 is determined in one direction. On the other hand, there is a problem that the direction of the curan 1 does not turn in the correct direction unless it is properly aligned and mounted.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problem, and a curan which can be mounted in any direction without depending on the mounting direction of a mounting member on a mounting surface. It is intended to provide a mounting structure.

[0005]

According to the present invention, in order to achieve the above-mentioned object, the present invention has a cylindrical shape into which the engaging portion 2 of the callan 1 is inserted. A cylindrical mounting member 5 having a detent engaging portion 3 for performing a detent and fixed to the mounting surface 4, and is detachably attached to the mounting member 5 and inserted into the mounting member 5. An engaging member 8 that elastically engages with a concave groove 7 provided in the insertion portion 6 of the callan 1 to prevent the callan 1 from coming off;
The engaging portion 2 provided on the callan 1 is formed by serrations 9 provided along the outer peripheral wall of the insertion portion 6 of the callan 1, and the detent engaging portion 3 provided on the mounting member 5 is formed inside the mounting member 5. It is formed by serrations 10 provided along the peripheral wall.

[0006]

The insertion portion 6 of the callan 1 is inserted into the mounting member 5 mounted on the mounting surface 4 in advance, and the engaging portion 2 and the detent engaging portion 3 are engaged with each other. The rotation stop of the mounting member 5 and the retaining by elastic engagement with the engaging member 8 are performed, and the callan 1 is mounted.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on illustrated embodiments. As shown in FIG. 1, the currant 1 is formed to have an insertion portion 6 at its lower end. The insertion portion 6 here is formed so as to be thinner than the outer diameter of the callan 1, and a serration 9 is provided in the upper part along the circumferential direction, and the engaging portion 2 is formed by the serration 9. A groove 7 is formed in the lower part of the insertion part 6 along the circumferential direction.

The mounting member 5 is a cylindrical member having a flange 5a at the upper end, a male screw 5b formed on the outer peripheral surface, a detent engaging portion 3 formed on the inner peripheral surface, and a lower part on the outer peripheral surface. Has a mounting groove 11 formed therein. The mounting groove 11 extends to the inner peripheral surface of the mounting member 5 so that the elastic engaging member 8 formed by bending a metal bar into a U-shape can be fitted. The detent engaging part 3 is the curan 1
The serrations 9 that can be engaged with the serrations 9 that form the engaging portions 2 provided on the base member are prevented from rotating with respect to the mounting member 5 by engaging the serrations 9 and the serrations 10 with each other. In this state, the callan 1 can be connected.

When the callan 1 is mounted on the top plate 4a such as a counter as the surface 4 to be mounted, first, the mounting member 5 is fixed to the top plate 4a. This is performed by fitting the mounting member 5 into the mounting hole 12 provided in the top plate 4a from above, and screwing the nut 13 to the male screw 5b of the mounting member 5 below the top plate 4a. Here, the engaging member 8 is fitted into the mounting groove 11 of the mounting member 5. In the figure, reference numeral 14 denotes a washer positioned between the lower surface of the top plate 4a and the nut 13.

Thereafter, the insertion portion 6 of the curan 1 may be inserted into the mounting member 5. At the time of this insertion, the serrations 9 as the engaging portions 2 provided on the insertion portion 6 are engaged with the serrations 10 as the detent engaging portions 3 provided on the mounting member 5, so that the rotation is stopped and the callan 1 is prevented. Is attached to the mounting member 5. The direction of the callan 1 can be freely changed by changing the engagement position of the serration 9 with the serration 10, and the mounting member 5 can be attached to the mounting surface without considering the mounting direction. 4, by adjusting the engagement position between the serrations 9 and the serrations 10 when the curran 1 is mounted on the mounting member 5, the curran 1 can be moved in any direction without being affected by the mounting direction of the mounting member 5. To the mounting member 5. Further, by inserting the insertion portion 6 of the callan 1 into the mounting member 5, the engaging member 8 is elastically engaged with the concave groove 7 provided in the insertion portion 6 as shown in FIG.
Is stopped.

[0011]

According to the present invention, as described above, the engaging portion provided on the callan is formed by the serration provided along the outer peripheral wall of the insertion portion of the callan, and the detent engaging portion provided on the mounting member. Is formed by serrations provided along the inner peripheral wall of the mounting member, so that the insertion portion of the callan is inserted into the mounting member mounted on the mounting surface, and the engaging portion and the detent engaging portion are formed. Are engaged with each other to prevent rotation of the mounting member, and are prevented from coming off by elastic engagement with the engaging member, and the callan is mounted,
By changing the engagement position between the serration as the engaging portion and the serration as the detent engaging portion, the callan is mounted in any direction without being affected by the mounting direction of the mounting member on the mounting surface. Is what you can do.
