Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bathtub overflow cover.

[Prior art and its problems]

Conventionally, a bathtub overflow cover has a structure as shown in FIG.

In this prior art, a cover body A is formed by integrally molding a cover part _a1 and a leg part _a2 protruding from the upper half of the periphery of the cover part _a1 using a metal material such as stainless steel. The space between the leg parts _A2 is used as an overflow guide part 4, and a heaton 200 is attached and fixed to the surface of the cover part _A1 for hooking a chain 6 connected to a bathtub drain plug. ing. However, this prior art has the following problems.

Since the overflow water guide part 4 is formed only in the lower half behind the cover part _a1 , it cannot cope with a sudden increase in the amount of bath water (for example, during bathing), and there is a risk of water overflowing from the upper edge of the bathtub. There is.

Since Heaton 200 is required, not only the necessary cost and processing cost are forced to rise, but also installation work is required separately.

[Technical issues]

The technical problem of this invention is to form a guide section for overflow water to the overflow hole not only in the lower half behind the cover but also in the upper half, and to connect it to the bathtub drain plug without using a heaton. The purpose is to make the chain hookable.

[Technical means]

The technical means of the present invention are as follows.

A cover body is formed by integrally molding a cover part and legs protruding from the circumference of the cover part at equal intervals and abutting against the bathtub wall using synthetic resin, and a gap between each leg of the cover body is formed. In addition to serving as a guide to the overflow hole, the lowermost leg is used as a hook for a chain connected to a bathtub drain plug.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

This cover body A is a cover portion that has a disk shape from the front.
It has a cap shape in which a slight folded part a1 _' is bent around the periphery of the cover part _a1 , and the legs abut against the bathtub wall B at equal intervals from the periphery of the cover part _a1 , that _is , the folded part a1'. It is constructed by integrally forming the part _a2 in a protruding manner.

In addition, this cover body A is integrally molded from ABS or other synthetic resin, and the cover part
_a1 Has a connection hole 100 to the connection fitting C in the center.

The folded portion a ₁ ′ has different folding amounts in the upper half 1 and the lower half 2, with the lower half 2 having a slight fold and the upper half 1 having a slightly wider fold than the lower half. There is.

The leg portions _A2 have four folded portions A2 spaced apart by 90° as shown in the figure to guide overflow water equally from the entire area behind the cover portion _A1 to the connecting fitting C attached to the overflow hole 3. ₁ ′ Formed protruding from the periphery.

Furthermore, among the legs a ₂ , the three legs protruding from the upper half 1 of the folded part a ₁ ′ have a protrusion amount of about 4 mm, and the lowermost leg a 2 protruding from the lower half ₂ When the leg portions a 2 and a 2 are brought into contact with the bathtub wall B by protruding by approximately 14 mm, a guide portion 4 (guide space) to the overflow hole 3 is formed between each leg portion a ₂ , a ₂ .

As shown in the figure, the lowermost leg part _a2 has a semicircular cross section that is thicker than the folded part _a1 ', and is connected to the hook ring 6' at the upper end of the chain 6 connected to the bathtub drain plug. It has a shape that can sufficiently withstand tensile strength when used as the hook part 5 by hooking it.

The actual dimensions of the cover main body A in this embodiment are as follows: cover part a ₁ diameter 83 mm, each leg part a ₂ length 15 mm, folding amount of upper half 1 at fold part a ₁ ′ 15 mm,
The folded back portion of the lower half 2 was 5 mm.

By the way, the folded part _a1 ' of the cover body A,
The boundary edge with the leg part _a2 is curved to prevent injury even if a hand is carelessly inserted into the guide part 4 (guide space).

FIGS. 3 and 4 show an attached state in which the cover body A is indirectly connected to the overflow pipe 101 via a connecting fitting C attached to the overflow hole 3. FIG.

[Function and effect of the idea]

As described above, the present invention forms a cover main body by integrally molding a cover part and legs protruding from the periphery of the cover part at equal intervals and abutting against the bathtub wall using synthetic resin. The space between each leg of the main body is used as a guide to the overflow hole, and the lowermost leg is used as a hook for a chain connected to a bathtub drain plug, so that the following effects can be achieved.

Because the legs are formed protruding from the periphery of the cover at equal intervals, the guide space (guide space) is smaller than in the prior art in which the guide to the overflow hole is formed only in the lower half behind the cover. The two functions of expanding the surface area and inevitably forming a guide space in the upper half behind the cover allow for quick drainage even if there is a sudden increase in the amount of bath water. This makes it possible to improve drainage efficiency and prevent water from overflowing from the upper edge of the bathtub as much as possible.

Since the lowermost leg is used as a hook for the chain connected to the bathtub drain plug, no heaton is required.

Therefore, not only can raw material and processing costs be lowered, but there is no need for heaton installation work.
Easy to manufacture.

Since it is integrally molded with synthetic resin, the cover part,
The legs and edges that protrude from the periphery of the cover are not as sharp as conventional metals such as stainless steel, so there is a risk of injury if you accidentally insert your hand or fingers while bathing. It is safe and has no leakage.

Since the legs protrude from the periphery of the cover part at equal intervals, although the ground contact area with the bathtub wall is small, the installation stability on the bathtub wall is very high and there is no wobbling.

As shown in the embodiment, the boundary edge between the cover part and the leg part may be curved, and in that case, safety when inserting a hand or finger can be further improved.

Thus, the intended purpose can be achieved.
