<p>#CMT# #/CMT# The curved guide channels (18) on each side of the door leaf (2) slope inward at a slight angle behind the vertical guide rails (20). They curve further away from the vertical at the top. Rollers (16) on the door leaf engage with the curved guide rails. #CMT# : #/CMT# Rollers (4) at the top of the door run in horizontal guide rails (6). There are guide rollers (10) on the top rail for pull cords (8) connected to a spring drive (15). #CMT#USE : #/CMT# Up-and-over tilting and sliding door for lockup garage. #CMT#ADVANTAGE : #/CMT# Spring drive or energy storage mechanism compensates for weight of door leaf, making it easy to raise and lower the door. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic side view of the door lifting mechanism. 2 : Door leaf 4 : Rollers at top of door 6 : Horizontal guide rails 8 : Pull cords 10 : Guide rollers for pull cords 15 : Spring drive 16 : Rollers on door leaf 18 : Curved guide channels 20 : Vertical guide rails.</p> |
