(57) The invention relates to a sunblind mainly composed of a framework or a system of
tubes, respectively, which can be mounted before a window, whereof the top of the
framework is formed by a casing in which a heat-resistant material, such as a prepared
cloth or screen, is wrapped into a roll of which its free end is secured in a bottom
lath, as a so-called, cloth string on which a relatively heavy tube is attached and
whereof said bottom lath at its ends is provided with elements which stick into lateral
guides of the framework and wherein they can move as such being part of the system
for locking or unlocking the heat-resistant cloth which can be lowered or raised manually
or otherwise from resp. into said casing.
According to the invention the locking/unlocking system (8a,8b) comprises at each
end of the bottom lath (5) a pen-like element (10) which can be moved in the lateral
guide (7) and whereby each element (10) inside said lateral guide is connected to
a movable plate (11) which for functioning of the system will co-operate with a cam-like
element (16) as arranged in said lateral guides.
