Cheek plate component for mounting roller shutters on window frames

摘要

The component forms part of a cheek plate (11), on which the casing of a roller shutter can be mounted. The casing has transverse grooves (314,317) on its upper and lower walls, and the inside of the cheek plate has stems (111,112) at the same levels.The stems project over the grooves, and are shaped to correspond with them. The grooves may be located near the corners of the casing, or near the middle of each side wall. They stems may be spring loaded, and may have lugs to engage in corresponding recesses in the grooves, in order to fix the position of the cheek plate relative to the casing.
