Description

[Detailed Description of the Invention] The present invention relates to an airtight device for a vertical rotating window.

This type of vertical rotating window provides good airtightness,
The structure is constructed with airtight material wrapped around the inside and outside, but due to the relationship between the cross-sectional structure of the window frame and the airtight material,
There was a drawback that it was difficult to open and close.

To explain this based on Figures 1 to 3,
As shown in FIG. 1, a rotating shaft is provided in the center of the window frame A so that the shoji B can be rotated.

The window frame A is composed of upper and lower frames 1 and 2 and both vertical frames 3 (one of which is not shown). As shown in FIG. 2, the upper frame 1 has a bearing portion 5 in the center of which a rotating shaft 4 is fitted, which is recessed upward, and horizontally provided inner and outer top plates 6 and 7 are provided inside and outside of the bearing portion 5, respectively. Further, as shown in FIG. 2, the lower frame 2 has a bearing part 9 in the center in which the rotating shaft 8 is fitted, which is recessed downward, and inner and outer bottom plates 10 and 11 are provided horizontally on the inside and outside of the bearing part 9, respectively. ing. Further, as shown in FIG. 3, both vertical frames 3 have a vertical groove 12 in the center, and vertical side plates 13,
There are 14.

On the other hand, shoji B has upper and lower frames 15 and 16 and both vertical frames 1
7 (one not shown). As shown in FIG. 2, the upper stile 15 is provided with a bearing fitting groove 19 in the center of the upper surface into which the bearing 18 that fits and supports the rotating shaft 4 is fitted, and an inner and outer airtight material mounting groove 2 is provided inside and outside of the bearing fitting groove 19.
