Sash supporting structure of hinged swinging window

摘要

A sash supporting structure of a hinged swinging window includes a sash bar hinge secured to a horizontal rail of a sash and having a pivot shaft, and a support groove formed in a horizontal frame member of a window frame and pivotally receiving therein the pivot shaft of the sash bar hinge. The support groove has a width dimensioned such that the sash bar hinge can be inserted in the support groove from the inner periphery side of the window frame. With this arrangement, the sash can be readily installed in the window frame without requiring prior connection between the horizontal rail or the sash and the horizontal frame member. The sash supporting structure further has a dislocation stop member secured to the horizontal frame member of the window frame and extending through a cutout opening in the sash bar hinge to prevent horizontal in-plane displacement of the sash bar hinge. The dislocation stop member is engageable with a portion of the sash bar hinge to prevent dislocation of the sash bar hinge from the horizontal frame member of the window frame.
