Description

Technical Field

[0001] The utility model relates to the technical field of thermal-break aluminum, in particular to the field of thermal-break aluminum windows, specifically to a variable middle stile. Background Art

[0002] The stile is a horizontal or vertical division of the window splicing frame. It is mainly used in building doors and windows to connect the window sash and window frame, fix the window sash, and seal the gap. If the door and window are not strong enough, the stile is needed for splicing. In the production of doors and windows, the presence or absence of the stile depends on the strength and design of the doors and windows.

[0003] After the two existing window sashes and the middle mullion are assembled, the window sashes on both sides are higher than the middle mullion, causing the two inner opening sashes to protrude from the plane while the middle mullion is recessed inwards. Alternatively, after the window sash on one side is fixed with the glass box middle mullion on one side, the window sash is higher than the glass, causing the inner opening sash to protrude from the plane, forming a convex ridge at the middle mullion, and there is a problem that the window sash and the middle mullion cannot be flush, which affects the appearance. Dust is easy to accumulate on the top edge of the inner opening sash. When the lower corner of the inner opening sash is slightly deformed, it will affect the sealing degree. Moreover, the protrusion at the lower corner of the window frame in the middle is easy to scratch the curtain, causing the curtain to be hooked and damaged. In addition, because the height of the inner opening window is close to the height of a child and is located in the middle, when moving at the window sash, the protruding lower corner of the inner opening window is easy to bump against people moving nearby.
