The present invention relates to a frame-unexposed heat-insulating folding window, and more particularly, to a window-type heat-insulating folding window in which exposure of a frame is suppressed when seen from the outside, Folding window.

A window is a window and a door which isolates the room from the outside and blocks the wind. The window is used for indoor lighting or ventilation of the room. The structure is basically a window frame (or door frame) (Or door) that is mounted on the door.

The window can be distinguished by the opening type or the non-opening type or the fixed type according to the opening manner.

On the other hand, a folding window for maximizing the open feeling is also a form of window window which is installed recently, unlike a fixed window or a door window window.

The structure of the folding window comprises a plurality of window frames connected by hinges and is configured to be opened and closed by a folding type. A free rotation roller is installed on the upper or lower part of the window pane or the upper window of the window frame to be separated from the window frame when folded or unfolded. And guided along the rails of the window frame.

When the folding window is completely folded as described above, most of the folding windows are opened based on the entire window area, so that the indoor space is connected to the outdoor space, so that the folding window is installed in a coffee shop, a restaurant, or a bar.

In addition, recently, folding windows have been installed in general houses or apartments that extend from the living room to the veranda, in order to distinguish between the veranda and the interior space for the purpose of insulation or selectively.

However, since the conventional folding window as described above requires a minimum rotation space used when folding or unfolding the window, it is configured to fold or unfold using a plurality of window frames having a narrow width in order to maximize space utilization. And minimizes the space. For this reason, when the window is opened for cooling in summer or for winter heating, the area of the metal window frame is exposed when compared with a general fixed window or a sliding window, so that the area of the window is relatively small and the window is vulnerable to insulation and mining. There is a structural drawback.

In addition, in the conventional folding window, when a plurality of window frames are formed with a smooth opening / closing action, the exposed area of the metal frame is wide and the thickness is relatively thin, There is a structural disadvantage that it is difficult to block the heat conduction between indoor and outdoor, and thus it is difficult to receive a high thermal efficiency rating because it is vulnerable to heat insulation.

In addition, the conventional folding window has a structure disadvantage that the connection between the hinge portion connecting the plurality of window panels and the metal window frame does not interrupt the heat conduction through the hinge portion by maintaining the contact between the metal and the metal.

In addition, in the conventional folding window, a method of joining a frame constituting a window and a glass is a method of fixing a frame portion by using a sealing material such as a general silicone, so that a fixed time between individual glasses and a frame takes much time, There is a structural disadvantage in that it can not provide sufficient support for wind pressure or vibration when strong winds or earthquakes occur.
