Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a unit bath that can be easily constructed indoors.

(Prior art) In conventional general unit baths, a plurality of wall panels are erected on the upper edge of the synthetic resin bath body that connects the bathtub and the washing area, leaving the entrance/exit area. As shown in the figure, the mortises m provided at the side ends of each wall panel 2j, 2k are connected in an H shape with a tenon n, and a ceiling panel is attached to form a bathroom, and a door can be opened and closed at the entrance. It is said that the structure is attached to the

(Problems to be Solved by the Invention) However, such a unit bath has the problem that a space is required above the wall panel in order to insert the tenon from above, and the assembly work thereof is also time-consuming.

(Means for Solving Problems) In order to solve these problems, the present invention connects multiple wall panels and attaches them to the upper edge of the bus body to form four walls, and then attaches a ceiling panel on top of the four walls. In the unit bath, a mushroom-shaped engaging part consisting of a shaft part and a head is provided on one side of the wall panels to be joined to each other, and a wide opening that allows insertion and removal of the head of the engaging part on the other side. and a narrow opening that allows only the sliding of the shaft portion of the engaging portion, and a stepped mounting piece is provided at each end of the engaged portion. In addition, a peripheral edge portion is provided around the engaged portion and is sloped so that the narrow opening side is lower than the wide opening side, and the engaging portion is located in the middle of the narrow opening portion. The gist of this invention is to provide a clip formed with a constricted portion whose width is narrower than the width of the shaft portion.

(Function) With such a configuration, the wall panels to be joined to each other can attach the head of the mushroom-shaped engaging part consisting of the shaft part and the head part to the stepped mounting piece in which the clip is formed. When inserted into the wide opening of the raised engaged part and then slid to the lowered narrow opening of the sloping peripheral edge, the engaging part will slide along the slope of the engaged part. Only the shaft portion slides through the narrow opening, without the head being drawn into the narrow opening or coming out, allowing the engaging portion to be pulled toward the clip. Accordingly, the shaft portion of the engaging portion crosses over the constricted portion at the intermediate portion of the narrow opening portion, and
The constriction part, which is narrower than the width of the shaft part, prevents it from coming out to the wide opening side, making it easy to fit and join, so there is no need for space above the wall panel, making it easier to assemble four walls. It becomes much easier.

Hereinafter, the unit bus of the present invention will be described in detail with reference to embodiments.
