[0001] This utility product is a thermal insulation device which is destined to insulate
the inbuilt box where the rolling shutter is originally installed.
[0002] The rolling shutter's boxes, used in the upper part of the window openings of a building,
are usually prefabricated U shape, concrete or PVC boxes, which may be simple or with
insulation within the walls of this box. After being installed, the rolling shutters
are accessible from the inside of the building through a cover placed at the top part
of the opening of the window. This cover is normally in wood and made to measure due
to the great range of types of windows in terms of window openings of and sizes of
walls.
[0003] The open part of the U shape boxes means that the outside air gets directly in through
the covers, which usually are connected to fittings, damaged parts or deficient structures
and therefore permit an exchange of heat and cold between the inside and the outside
of the buildings.
[0004] The insulation sheet used in the walls, floors and roofs are between 4 and 10 mm
thick, and are very flexible and easy to use; they are usually laminated, and combine
the properties of the materials to offer a high level of insulation against convection,
rays, and conduction.
[0005] The combination between a thermal insulation sheet with an easy, removable securing
system allows this device to form a efficient barrier between the inside and the outside
of a building at a place where, due to the characteristics of the rolling shutter's
boxes described above, the insulation is normally deficient. Moreover, this device
still keeps the possibility of having access to the rolling shutter for maintenance
through the cover and the same insulating material may be inserted again afterwards.
[0006] The insulation sheet, which length is the same as the inside of the rolling shutter's
box, has two Velcro strips allowing the device to be removed and put back as necessary;
One strip will fix the sheet along the inside wall of the box and the other will be
placed along the opening of the window or, if it is the case, on the brim of the cover
of the rolling shutters' box. The Velcro strip has two distinct parts which adhere
to each other by means of small filaments, and therefore it is necessary to place
it all along the areas mentioned, that is, of the window opening, and the rolling
shutters' boxes, so that the device may be installed.
[0007] This utility product will now be presented in more detail with the support of the
following figures where:
- fig. 1 represents a standard window opening in a building with inbuilt rolling shutters
seen from a main façade perspective;
- fig. 2 is a perspective seen from a cut line A to B as shown in fig.1;
- fig. 3 presents the device from a top perspective where the fitting system has been
applied and is seen from a cut line perspective C to D;
- fig. 4 presents a cut line perspective A to B as shown in fig.1 with the device already
installed.
[0008] In reference to the figures, we have in fig.1 the representation of a standard window
opening with rolling shutters.
[0009] The cut line perspective in fig.2 illustrates the exchanges of temperatures between
the inside and the outside of the building represented here by the arrows and this
due to the rolling shutters. Frame 1 where the shutter 2 goes down when used has normally
a play of 5 to 10 millimetres, so that the mechanism may work without any problems,
and this allows the air from the outside to circulate freely in the shutters' box
3. The fittings of the cover 4, and its thickness - normally of only a few millimetres
-, permit the exchange of temperatures from the outside and the inside passing through
the shutter's box.
[0010] Fig.3 represents the insulation device, which length is equal to the length of the
inside of the shutter's box and the width similar to the width of the box (In a great
majority of cases the boxes available on the market are 30 centimetres wide).This
allows it to adapt to the various positions of the window openings in relation to
the outside of the shutters' boxes. The device has a removable fitting system, constituted
by two Velcro strips 5, on the two longer sides of the insulation sheet.
[0011] Fig.4 presents the utility product applied to a standard window opening through a
cut line perspective. The insulation device 6 is fixed to the inside wall of the shutter's
box by Velcro strips in 7 and directly to the window opening or, if there is one,
to the brim of the cover of the shutter's box in 8. To secure the device, the corresponding
part of the strips has previously been placed along these areas.
1. Insulation device for rolling shutter's boxes, constituted by a thermal insulation
sheet with the same length as the inside of the shutter's box and approximately the
same width (the majority of the boxes on the market are of 30 centimetres wide), so
that it adapts to the various windows openings available on the market.
2. Device regarding claim 1, includes a removable securing system constituted by two
Velcro strips placed on the two longer sides of the insulation sheet which stick the
device along the inside wall of the rolling shutter's box (7) and along the brim of
the box's cover, if there is one, or directly to the window opening (8), allowing
it to be easily removed and reinstalled and also guarantees access to the rolling
shutters' box for maintenance.
