(54) | Aluminium box for frames rolling shutter with cast thermo block of sides and heat insulation |
(57) The invention concerns aluminium boxes for frames' rolling shutter in which: a) the
cast sides (rolling shutter's box caps) consist of two cast parts (1 and 2) between
them is created an injection of polyamide (3), b) at the upper (8 & 9) and the lower
(10 & 11) aluminium profile of the box there is a double thermo block with polyamides
(14 & 15) stapled by a special press and as a result the polyamides of the profiles
(upper-lower) and the polyamide (3) of the two cast sides are placed next to each
other and the thermo block is continuous, c) in the internal of the rolling shutter
(inside part) an insulating material (17) is placed, formed by a pantograph. The boxes
are easy in usage; they have a complete thermo block in the same position and in a
same distance from the space's internal as well as the thermo blocked frames are simple
in assembling and in their manufacturing and heat insulated.
