STAY FOR HOPPER WINDOW, AND HOPPER WINDOW

摘要

PROBLEM TO BE SOLVED: To adjust the opening angle of a sash by a simple structure without requiring a lateral space in a hopper window and improve the aesthetic appearance of the window. SOLUTION: A right side stay 30 for a hopper window comprises a projecting part 33c of a sash side arm 33, side parts of a window frame side arm 31, a locking projection 36c of a movable stopper 36c, and a projection 33e of the sash side arm 33 which are so formed as to prevent the sash 20 in an open state from further changing its attitude in the opening direction. This is also applicable to a left side stay 30 bilaterally symmetric with respect to the stay 30 for the right side stay 30. COPYRIGHT: (C)2008,JPO&INPIT
