Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem that since a conventional cloth curtain cannot insulate radiation heat, in summer, radiation heat entering from windows heats a building and, in winter, emission of the room temperature to the outside through the windows cools the building. <P>SOLUTION: This heat-insulating aluminum foil curtain can be freely extended/contracted in the vertical direction or horizontal direction by bending the aluminum foil into a bellows shape or winding it into a roll, is disposed inside the daylighting part such as windows, hinged doors, and doors of a building, and is opened/closed by vertically or horizontally extended/contracted. This heat insulating structure of the daylighting part is disposed inside the window of the building so as to be spaced therefrom to form a heat-insulating space between the heat-insulating aluminum foil curtain and the window. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention reflects solar heat, surface heat, radiant heat from heat sources such as room temperature, etc., intrusion of heat into the building from daylighting parts such as building windows, hinged doors, doors, etc., and heat from the daylighting part to outside the building. The present invention relates to an aluminum foil heat insulating curtain that prevents discharge and a daylighting portion heat insulating structure in which the curtain is disposed inside the daylighting portion.

  Cloth curtains are slidably suspended on curtain rails, guide bars, etc. inside the daylighting parts such as windows, hinged doors, and doors of buildings, so that sunlight does not enter the room during the day by closing the curtains. In the nighttime, indoor light is prevented from leaking outside.

  Although conventional cloth curtains can block sunlight and indoor light to some extent, most of the radiant heat generated by each heat source such as solar heat, surface heat, and room temperature is absorbed by or passes through the curtain. In the summer, radiant heat from the outside enters the building from the daylighting section and the room gets hot. In winter, the room heat gets out from the daylighting section and the room gets cold.

  The present invention can be detachably installed inside the daylighting part, has high heat insulation performance, and is provided inside the daylighting part to reflect the radiant heat from the outside and prevent the radiant heat from entering the room from the daylighting part. It is possible to provide an aluminum foil heat insulating curtain that can reflect indoor radiant heat and prevent emission of radiant heat from the daylighting section to the outside, and a daylighting section heat insulating structure using the aluminum foil heat insulating curtain.

  The aluminum foil heat insulation curtain of the present invention is the aluminum foil heat insulation curtain according to claim 4, wherein the lower support part is provided at the lower part of the curtain body, and the left and right ends of the lower support part are the daylighting parts. It is possible to move up and down by being guided by left and right guides arranged vertically on the inner left and right.

  The aluminum foil heat-insulating curtain of the present invention has a winding shaft at one end in the winding direction of a curtain body in which aluminum foil is wound in a roll shape, and a support portion at the other end, as described in claim 6, It can be supported vertically so that it can rotate inside the daylighting part such as windows, hinged doors, doors, etc. of the building, and the support part is an upper and lower guide arranged horizontally on the upper and lower sides of the daylighting part. The curtain body is supported so that it can be guided and slid. When the winding shaft is rotated, the curtain body is wound around the winding shaft and closed sideways, and when the winding shaft is rotated in the reverse direction or the support portion is slid away from the winding shaft. It is unrolled and spreads horizontally.

  As described in claim 7, the aluminum foil heat insulating curtain of the present invention is provided with winding shafts at both left and right ends in the winding direction of the curtain body in which the aluminum foil is wound in a roll shape, and the two winding shafts have upper and lower ends. Can be supported vertically so that it can be guided to slide and rotate by the upper and lower guides arranged horizontally above and below the lighting part of the building window, hinged door, door, etc., and the curtain body rotates each winding shaft It is wound around it and closed sideways, and each winding shaft is reversely rotated to unwind and spread sideways.
