Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a chain attachment structure attached to a bathtub or washbasin.

[0002]

[Prior art]

 Generally, in a bathtub or washbasin, it is necessary to provide a drainage hole for draining water or hot water and cover the hole with a plug.

Then, the stopper is connected to a bathtub or a wash basin by a chain. That is, in the case of a bathtub, a fitting was attached to the side wall of the bathtub, one end (base end) of the chain was connected to this attachment, and the other end (tip) of the chain was connected to the stopper.

Further, each of the mounting bracket and the plug has a boss portion provided with a through hole, and the through hole of each boss portion is provided with a single portion between end portions of a ring body composed of a double winding ring. It was inserted and the chain was linked to this ring.

[0005]

[Problems to be solved by the device]

 However, as shown in FIG. 6, on the side of the mounting bracket c, the dimension between the ends b and b is large, and the ring body a slides in the through hole d of the mounting bracket c. It rotates about its axis by a specified angle (range). Therefore, a finger or the like may enter between the one end b and the boss e during cleaning or handling, and the finger may be damaged at the end b. In addition, in FIG. 6, f is a chain.

Similarly, on the plug side as well, there is a risk that the finger may be damaged at the end of the ring body. Therefore, it is an object of the present invention to provide a chain attachment structure that is safe without being injured even during washing.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, one chain mounting structure according to the present invention has a boss portion provided with a through hole and connects the base end of the chain to a mounting bracket which is mounted on a bathtub or washbasin. A chain attachment structure for connecting a chain, the end of which is separated by a predetermined dimension along the circumferential direction and which is composed of a double-wound ring to which the chains are connected, and the end of the ring body The single portion between the portions is inserted into the through hole of the boss portion, and the dimension of the gap between the end portion exposed from the boss portion and the boss portion is set to a dimension that prevents finger entry. At this time, it is preferable that the gap size is 0 mm to 3 mm.

Another chain attachment structure is a chain attachment structure for connecting a tip of a chain to a stopper having a boss portion provided with a through hole and for covering a drainage hole, the end of which is attached. A ring body made of a double-wound ring in which the chains are connected to each other at a predetermined size along the circumferential direction, and the chains are connected to each other; The size of the gap between the boss and the end exposed from the boss is inserted into the through hole of the boss. At this time, it is preferable that the gap size is 0 mm to 3 mm.

[0009]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 and 2 show a chain mounting structure according to the present invention. For example, as shown in FIG. 3, this structure includes a mounting bracket 3 mounted on a side wall 2 of a bath 1 and a chain 4 base. It is for connecting the ends.

Therefore, the mounting member 3 includes a disk-shaped base portion 5, a short cylindrical boss portion 6 protruding from the front surface center portion of the base portion 5, and a back surface of the base portion 5. The screw shaft portion 7 is provided so as to project from the central portion, and the boss portion 6 thereof has a through hole 8. Then, a nut member (not shown) is screwed onto the screw shaft portion 7, and the fitting 3 is attached to the side wall 2 of the bath 1.

In addition, a ring body 9 made of a double winding ring is inserted into the through hole 8 of the boss portion 6. Here, the double-wound ring is a double spirally wound metal wire (for example, stainless steel wire) having a predetermined length, and as shown in FIG. Will be located on the front and back of the page.

This is because the ring body 9 can be inserted into and removed from the through hole 8 of the boss portion 6. That is, as shown in FIG. 4A, if one end 10 is inserted into the through hole 8 of the boss portion 6 and the ring body 9 is rotated about its axis from this state, A single portion 11 between the portions 10 and 10 is inserted into the through hole 8 and the ring body 9 is held by the boss portion 6 as shown in FIGS. 1 and 2. Further, as shown in (b) of FIG. 4, the other end portion 10 is brought out of the boss portion 6, and from this state, the ring body 9 is rotated around its axis in the opposite direction to the above case. This ring body 9 can be removed by moving it.

Thus, as shown in FIGS. 1 and 2, when the single-piece portion 11 of the ring body 9 is inserted into the through hole 8, a gap provided between the end portion 10 and the boss portion 6 is formed. The dimension G is set so that the finger cannot enter, specifically, 0 mm to 3 mm. Therefore, a finger or the like does not enter the gap and the finger or the like is not damaged.

The chain 4 has a connecting tool 12 for connecting the chain attached to one end (base end) of the chain 4, and the base end of the chain is connected to the ring body 9 via the connecting tool 12. The connector 12 includes a ring portion 13 into which the ring body 9 is inserted, and a short tubular portion 15 into which the ball 14 on the proximal end side of the chain 4 is fitted.

Although the chain 4 is attached to the bathtub in the above description, the chain 4 can be attached to the washbasin with this structure. That is, if the mounting bracket 3 shown in FIGS. 1 and 2 is mounted on the washbasin, the ring body 9 to which the chain 4 is connected can be mounted on the mounting bracket 3.

Next, FIG. 5 shows, for example, as shown in FIG. 3, a mounting structure for connecting the tip of the chain 4 to the plug 19 for covering the drainage hole 18 of the bottom wall 17 of the bathtub 1. Also in this case, the plug 22 is provided with a ring body 22 formed of a double ring which is inserted into the through hole 21 of the boss portion 20.

That is, like the ring body 9, the ring body 22 has its end portions 23, 23 separated from each other by a predetermined size along the circumferential direction, and the single portion 24 thereof is inserted into the through hole 21. As shown in FIG. 5, the gap dimension G between the end portion 23 and the boss portion 20 is such that the finger cannot enter, for example, 0 mm to 3 mm. Incidentally, also in this mounting structure, the plug 19 for covering the drainage hole of the washbasin may be held.

Therefore, even in this mounting structure, a finger or the like is not damaged when opening / closing the hole 18 by the plug 19. The tip of the chain 4 is connected to the ring body 22 by the above-mentioned connecting tool 12.

The outer diameter and the wire diameter of the ring bodies 9 and 22 can be freely changed. The outer diameter is, for example, about 15 mm to 30 mm, and the wire diameter is, for example, , 1.2 mm to 2.5 mm is preferable. That is, this degree does not hinder the user during bathing and is easy to insert into the through holes 8 and 21 of the boss portions 6 and 20.

[0021]

[Effect of the invention]

 Since the present invention is configured as described above, it has the following effects. According to the chain attachment structure of the first aspect, the chain 4 can be safely and reliably held without damaging a finger or the like during washing or handling. According to the chain attachment structure of the second aspect, cleaning and the like can be performed more safely. According to the chain attachment structure of the third aspect, it is safe without damaging a finger or the like in the operation of covering the drainage hole with the plug, and the chain 4 can be reliably held. According to the chain attachment structure of the fourth aspect, it is possible to more safely perform the lid-covering operation of the holes.
