part 16 secured to the end bar of the screen and is provided with a locking element

space below a locking surface 42 holds the screen in the desired position. Further
downward and rearward movement of the locking element 32 enables it to pass behind
a stop 46 through a gap 54 therebelow and then into a return passage which allows
the blind to retract. The upper part of the ramp 38 can be arranged to flex or move
out of the way to allow passage of the locking element 32. An alternative structure
mounts a locking element on the lateral guide and a catch member is provided on the
end bar to cooperate therewith. |
