Tilting mechanism for window, door, etc. - has gearbox with worm and sector connecting motorised or hand-turned drive shaft and tilting window arm

摘要

The tilting device has a gearbox (10) with a worm drive, the drive shaft being motorised (40) or hand-operated (12) and the output gear carrying the lever for the window, etc. The drive shaft is threaded within the housing, therefore moving axially as it rotates. Inside the gearbox, the shaft has a gear rack, engaging with the teeth of the output gear, this being a sector gear. The peripheral span of the sector corresponds to the required angular movement of the lever. The gearbox housing is in two parts, one for the drive shaft and one carrying the output gear. ADVANTAGE - Angle of window tilt is pre-defined in gearbox.
