Description

[Detailed Description of the Invention] The present invention relates to improvements in bathroom panels used for ceilings and interior wall materials in bathrooms and the like.

In recent years, bathroom panels in which synthetic resin foam such as vinyl chloride can be continuously stretched while maintaining watertightness have become widely used.
This bathroom panel, for example, as shown in Figure 1,
A bent protrusion 12 extending outward is provided slightly inwardly at one side end of the panel body 11 to form a connecting groove 13, and a supporting strip is provided at the other side end of the panel body 11. 14 in the longitudinal direction and is inserted into the groove 13. When the panel is stretched, the connecting protrusion 15 is inserted into the groove 13 as shown in FIG. By inserting the connecting protrusion 15 into the connecting groove 13, the supporting strip 14 acts like a fulcrum of a lever within the connecting groove 13, so that the connecting portion 10 between each panel is watertight. I am now able to retain my sexuality.

However, in the bathroom panel having such a structure, when the connecting protrusion 15 is inserted into the groove 13, the supporting legs 16
As shown in Fig. 2, the panel body 11 side will lift up, so when installing it on a ceiling, hold the panel body 11 with one hand until the bent protrusion 12 of the panel is nailed. Particularly in the case of a wide panel, the central part of the panel body 11 curves upward even after insertion, making it difficult to stretch it flush.

Therefore, in view of the above, the present invention not only simultaneously prevents the lifting of the bathroom panel when it is inserted and the lifting of the central part due to warpage after insertion, but also improves the watertightness of the connecting part. The object is to provide an even better bathroom panel, and in particular, the gist is that the connecting protrusions of the panel are curved to bulge upward in the width direction of the panel.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

The bathroom panel A is integrally molded from a heat-insulating synthetic resin foam such as vinyl chloride.

A bent protrusion 2 is provided slightly inward from one side end of the panel body 1, extending approximately at a right angle toward the back surface of the panel body 1, and then bent at a right angle from the extended end to extend approximately parallel to the back surface of the panel body 1. A connecting groove 3 is formed by the gap generated between the bent portion of this protrusion 2 and the side end face of the panel body 1.

On the other hand, the panel body 1 is attached to the other side edge of the panel body 1 with an appropriate inclination from that side edge.
A connecting protrusion 5 is provided which extends approximately the thickness of the panel main body 1 in the direction of the back surface, bends parallel to the back surface of the panel main body 1, and further extends outward as it is. This connecting protrusion 5 is formed in a curved shape that bulges upward in the width direction of the panel, and when this protrusion 5 is inserted into the above-mentioned groove 3, as shown in FIG. The protruding piece 5 is elastically deformed to be supported by the two contact surfaces 5a and 5b on the lower surface of the protruding piece 5.

Therefore, the force that the protrusion 5 receives within the groove 3 is:
Since it is firmly and stably received by the two contact surfaces 5a and 5b and the upper surface of the protruding piece 5, the panel body 1 is prevented from lifting up during insertion, and the upper surface of the protruding piece 5 is elastically deformed to form a groove. Since it is in close contact with the upper surface of the strip 3, the watertightness of the connecting portion 10 is also improved.

In order to further improve the watertightness of the connecting portion 10, as shown in FIG. It is also possible to adopt a structure in which the engaging parts 6 and 7 formed in the two parts are integrally engaged with each other.
Engagement grooves 6, 6 and engagement protrusions 7, 7 as shown in FIGS. 5b and 5c may be formed.

As can be understood from the above description, the bathroom panel of the present invention provides the following unique effects due to its structural features.

That is, by inserting the connecting protrusion 5 into the connecting groove 3, it can be easily temporarily fastened, and after temporary fastening, the bent protruding piece 2 can be fixed flush with the nail 8, etc., without any lifting due to warping of the central part. Can be stretched in a shape.

Further, when the connecting protrusion 5 is inserted into the connecting groove 3, the force received from inside the groove 3 is supported by the two contact surfaces 5a and 5b on the lower surface of the connecting protrusion 5 and the upper surface of the protruding piece 5. Therefore, it is possible to effectively prevent the panel body 1 from lifting up when it is inserted, and therefore, even when the panel is installed on a ceiling surface etc., the panel body 1 can be fixed with nails 8 or the like. There is no need for the troublesome effort of holding it in place by hand.

Furthermore, since the connecting protrusion 5 is formed into a curved shape that bulges upward in the width direction of the panel, when the connecting protrusion 5 is inserted into the connecting groove 3, it deforms due to its own elastic deformation. It completely closes the gap that occurs on the upper surface of the groove 3 and has extremely good watertightness. Therefore, it is extremely suitable as a wall material for places with high heat vapor pressure, such as sauna rooms.
