Description

[Detailed explanation of the idea] The present invention relates to a lid for covering a bathtub.

BACKGROUND ART Bathtub lids have traditionally been used to ensure safety by preventing children from falling into the bathtub and drowning, or from falling into high-temperature water and getting burned.

A stopper that protrudes downward is fixed to the bottom of the lid to prevent the lid from sliding off the top of the bathtub.This stopper comes into contact with the inner wall of the top of the bathtub and prevents it from slipping. Ru.

Bathtubs come in a wide variety of shapes, and therefore the lids that can be placed over these bathtubs also come in a variety of shapes.

Accordingly, the mutual spacing of the stoppers fixed to the lid is predetermined and fixed.

Therefore, lids of various sizes have stoppers attached at different intervals, and there are many types of bathtub lids, which makes inventory management and sales troublesome.

In addition, even if the lid is pre-fabricated to fit the bathtub, if the tile wall extends to the periphery of the bathtub, the lid must be shifted over the bathtub and placed over the bathtub. Therefore, it is not possible to cover the lid tightly.

Therefore, the bathtub is repositioned or the lid is turned over and the stopper is used without any use.

The main purpose of the present invention is to provide a bathtub lid that is commonly used for various bathtubs.

FIG. 1 is a perspective view of bathtub lids 1 and 2 according to the present invention,
The bathtub 3 is also shown.

This bathtub 3 is covered with two sheets of Ml, 2 facing each other, and upper inner walls 4a to 4 of the bathtub covered by the lids 1 and 2.
d is indicated by a phantom line 5.

Stoppers 6 to 13 are provided on the lower surfaces of the lids 1 and 2.

FIG. 2 shows a cross section of the vicinity of the stopper 6 along the section line ``---'' in FIG.

A mounting hole 14 is bored in the lid 1.

A threaded portion 16 of a mounting screw 15 passes through the mounting hole 14 gently.

The threaded portion 17 of the mounting screw 15 is provided with a groove for receiving a screwdriver.

A threaded portion 16 of the mounting screw 15 is screwed into a threaded hole 18 of the stopper 6 on the lower surface of the lid 1.

FIG. 3 is a perspective view of the stopper 6 and the mounting screw 15.

The stopper 6 has a truncated conical shape and projects downward from the lower surface of the lid 1.

The screw hole 18 is eccentric from the axis of the stopper 6, so that the stopper 6 is asymmetrical with respect to the axis of the screw hole 18.

The other stoppers 7 to 9 also have the same structure as described above.

Spacing between stops 6 and 8 and stops 7 and 9
The spacing is approximately equal to the pair of opposing upper inner walls 4a, 4b of the bathtub, and the upper inner walls 4a, 4b can be contacted.

Therefore, Ml,2 is prevented from sliding between the pair of inner walls 4a, 4b.

If the shape of the bathtub 3 is different, it is sufficient to tighten the mounting screw 15, rotate the stopper 6 to an appropriate angular position, and fix it by turning and tightening the mounting screw 15 at that position.

In this way, the lid 1 can be used in common even when the spacing between the upper inner walls 4a and 4b of the bathtub is different.

Stoppers 10 to 13 according to the present invention are also attached to the other lid 2, and these stoppers 10 to 13 can also be rotated in the same way, and can be commonly used for bathtubs 3 of various sizes. .

The stoppers 6.8; 11, 13 also stop the upper inner wall 4c of the bathtub.
.

4d, thereby causing the lids 1 and 2 to contact the inner walls 4c and 4a.
sliding along the gap is prevented.

Between the tops of the stoppers 6-13 (indicated by reference numeral 19 in FIGS. 2 and 3) and the bottom surfaces of the lids 1, 2,
A packing made of a material such as rubber and having the same shape as the tops 19 may be interposed.

By doing so, the threaded part 16 and the threaded hole 18 can be sealed by the waterproof effect.
The firmly tightened condition is maintained, and loosening of the mounting screw 15 is prevented.

The stoppers 6 to 13 may have a shape other than a truncated cone, such as a triangular prism or an oblong cylinder.

A bolt may be implanted in each of the stoppers 6 to 13, passed through a mounting hole drilled in the lid, and tightened with a nut on the top surface of the lid.

As described above, according to the present invention, the stoppers having an asymmetrical shape with respect to the axis of the mounting part are bored in spots so that they can be fixed at appropriate angular positions, so that the stoppers can be rotated. The stopper can be adjusted so that it does not come into contact with the opposing upper inner wall of the bathtub and slide off.

Therefore, the lid can be commonly used for bathtubs of various shapes.

Therefore, inventory and sales management of bathtub lids becomes much easier than in the past.

Furthermore, the lid can be used by adjusting the stopper according to the construction situation of the bathtub, eliminating the need for consideration regarding the lid during construction.
