<p><P>PROBLEM TO BE SOLVED: To configure an inner window for heat insulation so that it can be easily assembled, simply matched with a dimension of a building opening, and mounted in the inside of an outside window of the building opening. <P>SOLUTION: An inner window mounted in a frame of a building opening is configured by joining outer frame materials 11, 12 positioned on four peripheral sides of an outer window side and inner frame materials 21, 22 disposed in the inside of the outer frame materials so as to sandwich a translucent plate 7 together. Shape retentivity is given to a peripheral frame of the inner window by connecting the longitudinal and transverse metal outer frame materials 11, 12, each having a receiving surface 15 for the translucent plate on the inner peripheral side of a hollow tubular body part 14, at four corners, and the translucent plate is mounted in such a manner that four peripheral sides thereof are attached to the four receiving surface 15 via loop fasteners 8, respectively. The inner frame material is made of a synthetic resin and has a form of a cover encapsulating an indoor side of the outer frame material of each of the four peripheral sides, and is provided with locking hooks 24, 25 and is provided with a flexible tongue piece 26, which presses the translucent plate toward the receiving surface side, in a part facing the receiving surface. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
