Description

[Detailed Description of the Invention] The present invention relates to the improvement of a foldable bath lid, and in particular, the adjacent lid constituent units are arranged such that one longitudinal end is at a top angle and the other longitudinal end is at a top angle. The lid structural units having a rectangular cross section can be folded together by being alternately connected via connecting members at the bottom corners, and both the front and back sides can be used by contacting the top surface of the bathtub. This article relates to a folding bath lid.

Bath lids can be broadly divided into combination lids that use two or more plate-shaped items side by side, shutter lids that are rolled up by connecting a number of long and thin members, and original type lids that are called folding lids. There are three types.

Among these, folding lids have the advantage of being lightweight, easy to use, and do not take up much space, but the ones currently on the market are made of rectangular plywood cores lined up at slight intervals, and are made from vinyl chloride on both sides. Most are wrapped in a sheet and sealed with high-frequency welder.

Although this conventional folding lid is relatively inexpensive, it has a serious drawback in that the vinyl chloride sheet on the outer circumferential surface is torn during use, making it unusable and having a short service life.

The present invention eliminates the drawbacks of the conventional folding lid mentioned above, and is highly durable and heat-retaining.The lid structural units, each having a nearly rectangular cross section, can be stacked and folded together. The purpose of the present invention is to provide a folding bath lid which can be used by placing the surface on the upper surface of the bath tub, and will be explained in detail below with reference to the drawings.

Figures 1 to 3 show one embodiment of the present invention, and 1 in the figure shows a lid structure made of a hollow body with a roughly rectangular cross section, extruded from synthetic resin such as polyvinyl chloride or styrene. The unit 1 consists of a slightly wide elongated member with flat front and back surfaces, and the internal space is reinforced by appropriately providing reinforcing ribs 2.

At both ends of the lid structural unit 1 in the width direction, one has a top corner,
On the other hand, grooves 3 for connection are formed in the lower corners, that is, the diagonal portions (Fig. 2), and the lid structural units 1 are arranged so that the grooves 3 are adjacent to each other, and a soft synthetic resin is used. Made of a material with good bending properties such as resin or olefin resin,
Engaging enlarged portions 5 are provided at both ends of the thin strip-shaped linking member 4, and the engaging enlarged portions 5 are fitted into the coupling groove 3 of the lid component unit 1 and bonded or welded to form a unit. It is constructed so that one comrade can be folded.

Although not shown in the drawings, by fitting a cap to the end face of the lid structural unit 1 to close the hollow portion, a bath lid that is aesthetically pleasing and has extremely good heat retention properties can be obtained.

In this case, if the end cap also closes the connecting portion, the unit body 1 and the connecting member 4 will be prevented from coming out, and therefore there will be no need for gluing or welding only by engaging them.

In this way, in the present invention, adjacent lid structural units 1 are alternately connected via the connecting member 4 with one longitudinal end at the top corner and the other longitudinal end at the bottom corner. Therefore, even if the cross section of the lid structural unit 1 is rectangular as in the present invention, it can be folded one on top of the other.

In other words, if adjacent lid structural units 1 are connected at the same position, it would be impossible to fold them one on top of the other, but in this proposal, they are connected alternately on the top and bottom surfaces. As shown in FIG. 2, each unit 1 can be stacked neatly and folded.

4 and 5 show other embodiments with different connection structures, and in the case of FIG. 4, connection members are attached to opposite sides of the lid structural unit by adhesive or the like, Figure 5 shows a lid structural unit made of hard vinyl chloride and a connecting member made of soft vinyl chloride, which are integrally molded together by twin-screw extrusion, and formed into connecting grooves at the other ends of adjacent lid structural units. The connection is made by fitting the enlarged part of the connecting member.

In this case as well, it goes without saying that the connection positions are alternately connected, such as the upper surface and the lower surface.

Conventional folding lids are made by wrapping a plywood core in a vinyl chloride sheet, and the sheet itself is as thin as 0.3 to 0.5 mm thick. When welding this with a high-frequency welder, the welded part becomes particularly thin and can easily tear. easy.

In this regard, the connecting member of this proposal is made of a material with good bending characteristics and the wall thickness can be ideally designed, so even if this part is bent every time it is folded, it will have a very long service life, and the main body will also be quite long. It has a sturdy structure due to its wide width and reinforced ribs, so it can withstand long-term use, can be used cleanly for a long time, is easy to handle, and provides an ideal bath lid that does not take up much space at a low price. It can be done.

Furthermore, as described above, according to the present invention, the lid structural unit having a rectangular cross section can be neatly folded, and there is no vertical directionality, so any surface can be placed on the top surface of the bath. This has the effect that it can be used by placing it in the same place.
