Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical and horizontal frame in which an indoor side member and an outdoor side member are connected by a heat insulating bridge member, and a plurality of panels can be freely rotated in the frame. The present invention relates to a louver window that is vertically arranged.

[0002]

2. Description of the Related Art In a louver window, vertical and horizontal frames are constructed by connecting inner and outer frame members made of aluminum alloy with a heat insulating material to reduce heat flow through the frame, thereby improving heat insulating properties. There is a plan. In the conventional louver window, when the louver is fully closed, the upper side of the uppermost panel or the lower side of the lowermost panel is in contact with the outdoor member, and the indoor portion of the outdoor member is defined by the panel. It is exposed in the indoor space.

[0003]

According to such a conventional structure, when the indoor / outdoor temperature difference is large, the indoor side of the outdoor member of the frame is exposed to the indoor space defined by the panel. However, there is a problem in that heat flow occurs through the exposed portion, which causes deterioration of the heat insulating property.

In view of the above problems, it is an object of the present invention to provide a louver window using a bridge material as a frame material, in which heat conduction through the frame material is reduced and heat insulation is improved. .

[0005]

In order to achieve the above object, the invention of claim 1 is a portion of the outdoor member exposed to the indoor space in the fully closed state of the louver, or an outdoor side of the indoor member. It is characterized in that a portion exposed to the space is covered with a coating material having low thermal conductivity.

According to a second aspect of the invention, the covering material is integrally formed with a portion for covering the panel mounting side surface of the bridge material.

According to a third aspect of the present invention, the interior side member and the exterior side member are connected by a heat insulating bridge member to form a vertical and horizontal frame, and a plurality of sets of multi-layer panels are rotated in the vertical frame part. The panel receiving parts of the upper and lower frame outdoor side members and the indoor side members are respectively provided with the panel receiving parts of the upper frame and the lower frame. While receiving the upper side of the upper outdoor side panel, the panel receiving portion of the lower frame outdoor side member receives the lower side of the lowermost outdoor side panel, and the panel receiving section of the upper frame indoor side member is the uppermost indoor side panel The panel receiving portion of the lower frame inner side member receives the lower side of the lowermost indoor side panel.

[0008]

According to the first aspect of the invention, in the louver window having a structure in which the panel is applied to the outdoor side member to close it, the portion of the outdoor side member exposed to the indoor side space is covered with the low thermal conductivity coating material. The temperature gradient on the surface of the outdoor side member on the indoor side is reduced, the heat transmission through the outdoor side member is reduced, and the heat insulating property is improved. Further, even in the structure in which the panel is closed against the indoor side member, the portion of the indoor side member exposed to the outdoor space is covered with the coating material having low thermal conductivity, so that the heat transmission is similarly reduced and the heat insulating property is improved. To do.

According to the second aspect of the present invention, the number of parts is reduced because the covering material not only covers the outside or the inside of the frame but also the bridge material.

According to the third aspect of the present invention, since the air layer between the inner and outer panels of the multi-layer panel is lined up with the bridge material, both the outdoor side member and the indoor side member are respectively indoor side and room side without a covering material. Without being exposed to the outside,
Heat insulation is improved.
