DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 is a sectional view of a window apparatus having a structure of a gear engagement system according to the present invention, and FIG. 2 is a sectional view of the window apparatus viewed from above.

The window frame 20 is fixed to the lattice structure 10 of the curtain wall unit. Sealants 23 and 24 are respectively attached to the portions where the window frame 20 and the lattice structure 10 start and end contact with each other So as to block the inflow of outside air.

The gaskets 21 and 22 may be made of ethylene propylene rubber (EPDM) to maintain airtightness by providing gaskets 21 and 22 at contact portions between the sealants 23 and 24. [

A hook 120 having a horizontal cross-section is integrally formed on one side of the window frame 20 and is elastically coupled with the escape prevention cap 110 as described later.

Here, the bar designates a shape extending in the plane of the drawing, and is used in the following.

Layer glass 40 is bonded to the window 30 rotatably by the window frame 20 by means of sealants 41 and 42. A window 30 is provided on one side of the window 30 corresponding to one side of the window frame 20, The stopper bar 130 having an annular horizontal section like the stopper 120 is integrally formed and is elastically coupled with the escape prevention cap 110 as well.

The separation preventing cap 110 has a horizontal cross section having a substantially rectangular shape and both ends separated from each other can be reliably joined to the hook 120, 130 having a circular horizontal section in a circular cross section.

The separated both ends of the departure prevention cap 110 can be forcibly opened and resiliently coupled by the resilient restoring force in a state of being engaged with the catch bars 120 and 130.

A thin sheet-shaped gasket made of a heat insulating material such as polyamide is interposed between the both ends of the departure prevention cap 110 and the engagement bars 120 and 130 so that the escape prevention cap 110 and the engagement bar 120, and 130, respectively.
