One Two Stop / window handle

One Two Stop
One Two Stop

When opening windows, people must touch the frame or glass, which is inconvenient and smudges the window.
This design modifies the handle of the window, limiting the handle to turn only 90° when pulled from up to down. The handle can be easily held to open the window, and serves as the locking and opening mechanism with the braking function. The window can be locked freely in any position.
