透明板が開示されている。(b) Prior art JP-A-56-92140 (hereinafter referred to as the first conventional example), JP-A-56-120548 (hereinafter referred to as the second conventional example), JP-A-56-120549 (hereinafter referred to as the second conventional example) 3), etc., include a plurality of transparent plates facing each other with a space in between, a transparent film that is stretched to divide the space between the transparent plates into two, and a space between the transparent plates that is maintained at a predetermined interval. A multilayer transparent plate is disclosed, which includes a spacer having a rectangular frame and supporting the transparent film in a stretched state.

し、そのしわや波をなくすようにしている。 In each of the above conventional examples, the peripheral edge of the transparent film is sandwiched between two spacers to maintain the transparent film in a stretched state, but in the first conventional example, heat shrinkage is applied between both spacers. After sandwiching the transparent film, the multilayer transparent plate is placed in a forced draft oven and heated to the extent necessary to remove substantially all wrinkles and waves on the transparent film. do. The transparent film, which has become easier to stretch due to this heating, is stretched, its peripheral edges are fixed with a spacer and a sealing member made of elastic adhesive, and the transparent film is cooled until the temperature of the transparent film falls below its softening point or transparent plate temperature. The transparent film is thereby contracted and its expanded state is improved. In addition, in both the second and third conventional examples, a transparent film that is flexible at room temperature is sandwiched between both spacers, and its four sides are fixed, and an elastic tensioner is provided within the spacer or close to the spacer. The elasticity of the member presses the peripheral edge of the transparent film to stretch the transparent film and eliminate wrinkles and waves.

透明板の生産性が悪くなくなつていた。 The transparent film used for such multilayer transparent plates has a square or rectangular shape, and when it is stretched, it is pulled outward by holding the center of the four edges. The accompanying wrinkles and waves appear on the diagonal lines of the transparent film, and the stretching operation is forced again to eliminate these wrinkles and waves, especially on the diagonal lines of the transparent film near the corners of the spacer. The work of rolling out wrinkles and waves was difficult, and the productivity of multilayer transparent plates was becoming poor.

ならなかつた。 Further, in the first prior art, in order to maintain the same pressure in both spaces divided into two by a transparent film, a hot needle is passed through a portion adjacent to the edge of the transparent film to melt that portion and form a small hole. However, there are some issues with manufacturing, such as the need to perform perforation work during the assembly process of multilayer transparent plates, and the risk of the transparent film tearing at the small holes during the stretching process performed after forming the small holes. Not only did it require more work steps, but it also required careful attention to the rolling process.
