Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a bathtub lid in which a plurality of independent lids are used side by side in a bathtub.

[Prior Art] Conventionally, as a bathtub lid of this kind, a hollow bath lid with a rectangular plane and made by molding hard synthetic resin, which is called a combination two-panel lid, is well known. Also, in 1977-
Publication No. 136532 describes cutting out several vertically long rectangular holes with the same width on both sides inside a sponge board, inserting plywood boards into the vertically long rectangular holes, gluing sponge boards to the top and bottom surfaces of each, and then A bathtub lid is disclosed in which longitudinal cut holes are formed alternately in the lower surface.

[Problems to be solved by the invention] In the conventional technology, the lid had a hollow structure, so its strength was weak. For example, if a child, such as a child, climbed on the lid placed in the bathtub, the lid would bend and fall into the bathtub. There was a risk of getting burned. In addition, the heat retention properties were poor because the radiant heat rising from the bathtub was absorbed by the lid. Furthermore, in the above-mentioned Japanese Utility Model Application Publication No. 49-136532, a plywood board is inserted into a vertically long rectangular hole cut out with the same width on the left and right sides, and a plurality of plywood boards are installed in parallel, so that the size of the bathtub opening is When cutting the lid to fit the size of the lid, there is a problem that the cut surface is sharp on the plywood, making it difficult to cut, and that the plywood is exposed, causing early corrosion of the plywood.

Therefore, this invention not only improves the strength and safety of the lid that is used in a bathtub with multiple independent lids, but also significantly improves the heat retention of the lid, and can be easily adjusted to fit the size of the bathtub opening. The purpose is to provide a bath lid that can be cut.

[Means for Solving the Problems] The present invention provides a bath lid in which a plurality of independent rectangular lids are arranged side by side with their long sides abutting each other. An opening was provided on one long side of the frame, a flat reinforcing plate was fitted into the opening, and a thin aluminum film was formed on the bottom of the frame and the reinforcing plate. A lower sheet made of foamed synthetic resin is provided, and an upper sheet made of foamed synthetic resin is provided to form a colored layer on the upper surfaces of the frame and the reinforcing plate.

Furthermore, the present invention provides a bathtub lid in which a plurality of independent rectangular lids are arranged side by side with their long sides abutting each other. A reinforcing plate smaller than the foamed synthetic resin sheet is provided offset to one long side of the lower foamed synthetic resin sheet, and an upper foamed synthetic resin sheet larger than the reinforcing plate is provided on the upper surface of the reinforcing plate. The peripheral edge of the resin sheet covers the peripheral surface of the reinforcing plate and is fixed to the lower foamed synthetic resin sheet.

[Function] The reinforcing plate increases the strength of the bath lid and allows the thin aluminum film to reflect the radiant heat rising from the bathtub. Cut the long side.

[Embodiment] An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
