<P>PROBLEM TO BE SOLVED: To solve the problem that a transparent plastic plate is deformed or separated by thermal expansion in the reception of direct sunlight, because the coefficient of linear expansion of transparent plastics is 10 times or more higher than that of linear expansion of glass, when the transparent plastic plate is fixed to the glass via a spacer. <P>SOLUTION: Tongue-and-groove plastics are bonded to the glass and the transparent plastics in such a manner that grooves of them are directed in directions opposite to each other, so that the glass and the transparent plastic plate cannot be bonded and fixed together; and a one-side tongue is inserted into the other-side groove. Thus, the transparent plastic plate can be freely expanded and contracted without coming off. The expansion and contraction of the transparent plastics can be absorbed by an elastic adhesive tape, and airtightness of a hollow layer between the glass and the transparent plastics can also be maintained. <P>COPYRIGHT: (C)2008,JPO&INPIT |
