Description

[Detailed Description of the Invention] The present invention relates to a heat insulating window whose heat insulation effect is enhanced by a screen.

In general, glass in windows of buildings, etc., easily allows sunlight and thermal energy to pass through, which causes a significant decrease in the efficiency of air conditioning and heating in summer and winter. In order to prevent this kind of decrease in heating and cooling efficiency, it is best to install an insulating screen to form an air layer between the windows and the window glass, and use this air layer to block heat. However, when installing the above screen, supporting members for attaching the winding shaft and guide members for opening and closing the screen must be separately installed along the window frame, so it is difficult to install the screen. There were disadvantages such as the work was very troublesome and installation errors were likely to occur.

The present invention aims to provide a heat insulating window that allows a screen to be stretched easily and accurately.In particular, the invention aims to provide a heat insulating window that allows the screen to be stretched easily and accurately.In particular, the winding shaft mounting part for attaching the screen winding shaft and the stile at the tip of the screen are guided. The window frame is characterized by a guide rail that is integrally formed with the window frame.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. In FIGS. 1 and 2, 1 is a window frame, which is made up of left and right vertical frames 1a, 1b, an upper frame 1c, and a lower frame 1d. A shoji 2 having a sliding structure with glass 3 is attached to the window frame 1, and a heat insulating screen device 4 is attached to the outside of the shoji 2.

The heat insulating screen device 4 comprises a heat insulating net 5 constituting the screen, and a winding section 6 in which the net 5 is wound around a winding shaft 8 which is rotatably supported in a cylindrical cover 7. and a frame 9 attached to the other end of the net 5,
The winding shaft 8 is configured to automatically wind up the net 5 using the elastic restoring force accompanying the torsion of a built-in spring as a driving source, but it is also configured to wind up the net 5 manually. Also, net 5
It is preferable to use a woven fabric made of a strong heat insulating material, such as a net made by weaving filaments with synthetic resin coating on the surface of glass fiber bundles.In this case, the shielding rate of the mesh should be relatively low. Make it bigger;
It is necessary to allow some air circulation to alleviate the temperature gradient near the front and back sides of the net.

When attaching the heat insulating screen device to the window frame 1, on the outdoor side surface of the upper frame 1c of the window frame 1, the winding part 6 is placed at a position that does not overlap with the surface including the glass shojis 2, 2. A box-shaped mounting portion 10 having an opening 10a wide enough to allow insertion and removal of the cylindrical cover 7 from the outside on the lower surface.
On the other hand, guide rails 11 having guide grooves 12 are integrally formed on the left and right vertical frames 1a and 1b, respectively, and the cylindrical cover 7 of the heat insulating screen device 4 is attached to the mounting portion 10. In addition to being fitted and fixed, engaging members 13, 13 protruding from both ends of the frame 9 are fitted and engaged in the guide groove 12 of the guide rail 11. In this case, at the lower end of the guide rail 11,
In order to maintain the net 5 in a closed state, it is desirable to provide a notch in the groove edge of the guide groove 12 for locking the frame 9.

In the illustrated embodiment, the opening/closing direction of the net 5 is the vertical direction, but it may also be the horizontal direction.

In the above-mentioned heat insulating window, as shown in FIG.
When the net 5 is closed, the heat conduction between the indoor and outdoor areas is interrupted, and it is possible to prevent the efficiency of air conditioning from decreasing due to this heat conduction. In particular, when the above-mentioned insulating screen device is used for heating in winter, since the insulating net has some air permeability, the temperature gradient near the front and back of the net is alleviated due to the ventilation, thereby preventing dew condensation on the net surface. can be prevented. Of course, the heat insulating net can be used to prevent sunlight from entering the room during the summer season.

Note that the heat insulating screen device 4 can also be attached to the indoor side.

As is clear from the detailed description above, according to the present invention, when attaching a heat insulating screen device to a window, a heat insulating net is placed on the outside surface of the window frame at a position that does not overlap with the surface containing the glass shoji. A box-shaped mounting part with an opening wide enough to allow insertion and removal of the cylindrical cover with a built-in winding shaft from the outside and a guide rail with a guide groove are integrally formed. (a) There is no need to separately install a special member along the window frame for attaching the screen device, and the configuration of the window frame becomes extremely simple.

(b) Since the cylindrical cover can be easily attached to and removed from the mounting part from the outside through a wide opening in the mounting part,
When attaching and detaching the cylindrical cover, there is no need to remove or disassemble the window frame, and the attachment and detachment work is very easy.

(c) Since the mounting part is formed at a position that does not overlap with the side surface of the window frame that includes the glass shoji, this mounting part limits the size of the shoji and reduces the opening area of the window. Therefore, the opening area of the window can be formed to the same size as that without the insulating screen device.

It is possible to expect significant effects unique to the present application, such as:
