Description

[Detailed explanation of the idea] This invention relates to a bathtub lid.

The bathtub lid has hollow members made of hard synthetic resin connected in parallel by connecting members made of soft synthetic resin.
It is known that blind caps can be attached to both end faces of a hollow member in order to prevent the end faces of the hollow member from being damaged due to impact when the hollow member falls onto a bathroom floor or the like. However, when a blind cap is attached, when the air in the sealed hollow is heated and expanded by hot water steam, the hollow member, which is easily deformed by heat, deforms and the lid of the bathtub is sealed. There were drawbacks that not only deteriorated the effect but also significantly impaired the external appearance.

In order to eliminate this drawback, a bathtub lid is disclosed in Japanese Utility Model Publication No. 56-9461, in which synthetic resin caps having holes communicating with the interior of the hollow member are fixed to both ends of the hollow member by welding or gluing. proposed by. However, when using a bathtub lid with this configuration, it is possible to prevent the hollow member from deforming and improve the sealing effect and appearance of the bathtub lid, but the bottom of the hole in the cap is connected to the inner surface of the bottom wall of the hollow member. It is difficult to match, and in addition, if the strength of the cap is not weakened, the size of the hole that can be made in the cap will be smaller.
Another disadvantage is that it takes time to drain the hot water that has entered the hollow member or the steam of the hot water that has condensed, and that it is inconvenient to handle the bathtub lid that has become heavy with condensed liquid.

Furthermore, since the cap is welded or glued to the end face of the hollow member and cannot be separated from the hollow member, even if the inner surface of the hollow member becomes dirty with water scale, etc., the dirty part cannot be easily cleaned and the bathtub lid cannot be separated. It becomes impossible to maintain good sanitary conditions.

The object of this invention is to provide a bathtub lid that can eliminate the above-mentioned drawbacks and is also suitable for saving material costs.

To describe an embodiment, in a bathtub lid 1 in which hollow members 2 made of hard synthetic resin are connected in parallel by connecting members 3 made of soft synthetic resin, openings 5 at both ends of the hollow members 2 are provided in a proportion close to the opening area of the hollow members 2. It is characterized in that an edge reinforcing ring 4 made of synthetic resin and having reinforcing ribs 6 and 7 formed thereon is removably attached. Adjacent hollow members 2, 2
are slightly different in size in this embodiment, but they may be of the same size, and the connecting member 3 of the hollow members 2, 2 has an engaging portion formed in the length direction of both ends of the hollow member. 2 may be fitted into connecting grooves provided on both sides in the length direction.

The edge reinforcing ring 4 made of synthetic resin is provided with a protrusion 4a having a shape that can fit into the hollow part on the end face facing the opening of the hollow member 2. Ribs 6 and 7 that protrude in the vertical direction are formed on the upper and lower inner surfaces of the opening 5 whose area is close to the opening area of the hollow member 2. In this embodiment, the ribs 6 and 7 are provided separately at upper and lower opposing positions, but they may be connected as one rib as shown by the two-dot chain line, and the edge reinforcing ring 4 The length provided on the inner surface can also be freely changed.

The strength of the hollow member 2 is reinforced by vertical ribs 8 provided therein, so that deformation can be suppressed to a minimum, and a non-slip member 10 made of soft synthetic resin is provided on each back surface that comes into contact with the top surface of the bathtub 9. There is.

Since this invention has the above configuration, if the bathtub lid 1 is placed on the bathtub 9 with the non-slip 10 facing down,
When the bathtub lid 1 is heated by the heat of hot water or steam and the air inside the hollow member 2 expands, the expanded air is passed through the large opening 5 of the edge reinforcing ring 4 at a slow speed that is not felt by the bather. It is possible to prevent the bathtub lid 1 from deforming due to heat by letting the heat escape into the bathroom as shown by arrow P in FIG. Therefore, not only the sealing effect of the bathtub 9 by the bathtub lid 1 is improved, but also the external shape can be maintained well.

Furthermore, even if the opening 5 is made sufficiently large, the edge reinforcing ring 4 can maintain appropriate strength by the reinforcing ribs 6 and 7, so that the hollow member 2 can be
By simply tilting the bathtub lid 1 in the length direction of the hollow member 2, the water vapor droplets condensed inside the hollow member 2 can be prevented from being damaged. Since it can be discharged very easily through the large opening 5 of the ring 4, the bathtub lid 1 has the advantage of being convenient to handle.

Furthermore, even if the inner surface of the hollow member 2 becomes dirty with water scale or the like, the dirt on the inner surface can be easily removed by removing the edge reinforcing ring 4 that can be attached to and detached from the end surface of the hollow member 2.
