Tilt & Turn windows can be opened in multiple directions by operating a single handle. The sash can be opened from the top for ventilation (tilt position), from the side for airing and cleaning (turn position), or locked in place (lock position). The user can sometimes trigger what we call ‘fall position’. This usually takes place when the user tries to get the window to tilt position. The user will see the window askew in its frame and will have the feeling that one of the hinges came loose.
To prevent this accidental triggering of ‘fall position’, TGP has designed a product. Called ‘Wrong Action Safety Device’, or WASP in short, it prevents the user from positioning the handle in tilt and turn mode at the same time.
WASP also acts as a sash positioner, or lifter. If fall position is somehow triggered, the window is raised easily back in place. WASP ensures that the sash stays in the desired position. Moving the sash position may prevent WASP from engaging properly with the keep or locking plate. The plate that the WASP will engage may need fine adjustment so the window stays in the correct position when the sash is closed. The maximum height the user should be able to lift the window has to be 0,5 mm.
