Abstract

The sealing system is based on different techniques carried out on the roller shutter system with view to limiting the passage of air. To this end profiled parts are created for or added to the extremities of roller shutters inserted in guides in order to obtain a continuous and not undulating abutment throughout the whole span of the window when the roller shutters are fully lowered. On the plane thus created the sealing gasket abuts, profiled in such a way as to adhere to the surface created. These guides can be equipped with a mobile system that makes the roller shutter adhere to the profiled gasket or gaskets. In abutment with the sill a gasket with a lip projecting externally is employed. In the upper part of entry into the shutter-box a special lip gasket is added with a profile designed to adapt itself to the roller shutter and is coupled with guide rollers. A gasket is interposed between the roller shutter slats.

DESCRIPTION OF THE INDUSTRIAL INVENTION ENTITLED:

"SEALING SYSTEM PROVIDING AIR. SOUND AND WIND INSULATION, BURGLAR RESISTANCE AND IMPROVED HEAT AND SOUND INSULATION IN ROLLING SHUTTER SYSTEMS AND THEIR SLIDING GUIDES AND FULL-PERIMETER RABBETS ON WINDOWS AND FRENCH WINDOWS"

DESCRIPTION

Reference to state of the art technique is related to seals created with brush gaskets both in the lateral guides and the full perimeter rabbets. These gaskets have the main function of protecting the rollers against wear due to sliding, especially those in aluminium, as well as reducing roller noise and battering caused by the wind. The air seal contribution is however limited. Often guides are used whose sizes are much greater than the roller shutter, especially when old ones are replaced, with the result that there is considerable passage of air through the guides, thus greatly reducing the roller's screening of air and noise when lowered. In the upper part, where it enters the roller-shutter box, there are no efficacious air sealing devices. This lack means that the insulation and soundproofing of the box must be rendered increasingly effective. These lacunae significantly worsen the value of the Uws heat transmission of the window, to the detriment of the building's energy costs, and result in mediocre soundproofing.

The system in question consists of the use of special devices and techniques with the aim of reducing air passage when the roller is in the closed position.

The most significant technique consists of creating a smooth surface in the final part of the profile, a modification obtainable in two ways: the first by deforming the profile, the second by adding a side cap.

With the profile deformation technique we create, at a certain distance from the end of the profile, a flat surface of variable width. In this way, at the end of the profile, a flat band is formed which interrupts the curved form of the profile towards the exterior of the window.

With the second technique the aim is to interlock, at the end of the roller, a profiled cap with the form of the body of the profile, created with a flat band of variable width which is matched to the curved form of the profile body.

Once the shutter is assembled with the various slats, a continuous band is obtained at the sides of the shutter, created at a margin established by the end of the shutter and suitable for being contained within the guides.

This technical detail is then integrated with special guides profiled in such a way as to adhere to the flat surface created on the shutter.

These guides are created with gaskets supported by structures positioned in correspondence to the plane in such a way as to best adhere. In this way the passage of air is considerably limited, since in a normal closed shutter it is difficult to obtain adherence of the guides with the shutter since the latter has a surface that is not linear but curved with view to improved rolling. With this new system the gaskets abut directly on a flat surface, limiting the passage of air while leaving the shutter's rolling capacity unaltered.

A mobile system may be added to these guides, manual or motorised, which when the shutter is in the closed position creates pressure on the part of the shutter opposite the gasket in such a way as to make it abut against the said gasket. The system can be enhanced by means of recesses created on the end part of the profiles comprising the shutter, in correspondence to the guides. The mobile system that brings the shutter to abutment is formed in such a way as to have projections which, while they thrust the shutter towards the external gaskets, interlock with the recesses created on the profiles. In this way the system also carries out an anti-burglary function since by locking the shutter in the guides it is harder to unhinge or remove it.

These guides can be created for both new installations and replacements. The difference between the two applications lies in the fact that the replacement guides are inserted in the already existing ones and can therefore project slightly to allow housing of the gaskets and any mobile locking systems.

Lastly, a gasket may be added to these guides, shaped according to the curved surface of the shutter. This profile can be brought to abutment with the shutter by a manual or motorised system in such a way as to reduce the passage of air from the guides.

The above techniques of course can be used for both sides of the profile with variable measurements and forms.

This technique is integrated with a profile inserted into the last slat of the shutter in such a way as to limit the passage of air where the shutter abuts with the sill. This terminal is created with a lip shape, projecting towards the exterior of the frame, in elastic material that can adapt to irregularities in the sill.

To limit the passage of air in the shutter-box a system is fixed external to the shutter, close to the box entry. This system is based on the use of an overhanging gasket which adapts to the undulations of the shutter during opening and closing. The gasket is created in material which allows it to slide on the shutter. Obviously a similar gasket may also be fitted between the roller and the frame. To keep the roller shutter at the right distance from the wall when deformed, small rollers can be used to lead the deformed slats to their original position. Characteristics and further advantages of this system will me made clearer by the detailed description below of forms of embodiment, illustrated by way of example and not limitedly in the following drawings.

Figure 1 in plate 1 shows the first contribution to the air insulation system: the deformation is carried out on the slat in such a way as to form a smooth surface (1) in which a special guide (4) can adhere more completely. The figure shows only the final part of the slat, i.e. the part inserted into the guide. Deformation implements a hollow surface (1) on the profile, carried out at an established distance from the end of the slat in such a way as to maintain the natural curve of the profile at the sides of the deformation (2) (3). The guide is created in such a way as to have a protruding longitudinal structure (5) which adheres to the hollowed surface of the roller shutter. The figure also shows the internal gasket (6) and a gasket (7) positioned directly on the profile in the abutting section.

Figure 2 in plate 1 shows a schematised section of a slat within the guides. The slat (8) can be seen interlocked in the guide. On the side of the deformation of the roller the guide has a structure (9) bearing a gasket (10) which adheres to the flat surface of the slat, considerably reducing the passage of air. A further gasket (11) can be seen on the opposite side with the function of reducing noise caused by friction and further reducing the passage of air.

Figure 3 in plate 1 shows, in a more detailed manner, the detail of deformation on the roller slat. Note the deformation (12) which creates a flat surface with the natural curve of the profile at the sides (13) (14). Figure 4 in plate 2 describes the terminal of the roller shutter. This new type of terminal (1) is fixed to the last slat (2), i.e. the one that abuts with the sill (3).

Figure 5 in plate 2 represents a variant of the roller shutter terminal. In this variant the terminal is equipped for the addition of a bolt. This variant also envisages a lip gasket (4) in the final part but differs from the variants shown previously in that there is bolt housing (5). Figure 6 in plate 2 describes in greater detail the form of the roller shutter terminal. Note the section (6) which is inserted into the last slat of the roller shutter and the two lips (7) (8) that adhere to the sill. Figure 7 in plate 2 represents a variant of the roller shutter terminal. This terminal is formed by two divided structures which are then assembled. The first structure (9) is inserted into the last slat of the roller shutter with the function of giving structure to the terminal, and gasket (10) is fixed beneath it.

Figure 8 in plate 2 shows a variant of the terminal. In this case a projection (11) is created which follows the curve of the roller shutter, creating a terminal best adapted to the profile and more pleasing to the eye.

Figure 9 in plate 3 represents a new guide to adapt to the system with deformation of the slat or addition of a side cap which simulates the deformation carried out on the slat. This new guide is useful in the replacement system, i.e. when the new guides are added over the existing ones. In these situations the problem is due to limited space. This new guide is additional to the existing one (1) but saves space since it has an L-shape, i.e. with one wall only (2). Of course this guide too envisages the system using a vertical structure with attached gasket (3) which abuts with the flat surface created or added to the roller. This type of guide is fixed to the existing ones by screws (4) or similar systems.

Figure 10 in plate 3 shows a system for insulating the box against the passage of air. This system is based on the use of an eyelash-shaped gasket (5) that adheres to the rolling shutter (10) in such a way that air does not filter through. This gasket is positioned on a support (6) which is fixed with screws or similar systems (7) to the external masonry (8). A supplementary structure (9) is then fixed to the support (6), the former carrying out the function of abutment for the cap (15) which is fixed to the last slat (16) to block rolling of the shutter. To make the drawing clearer, the guide (11) is also shown together with the lead-in to the guide (12). A profile (13) is shown, whose task is to lead the roller shutter in movement and reduce the passage of air. A solar panel (14) may be added to the external surface of this upper sealing system (14).

Figure 11 in plate 4 represents the section of the roller shutter (1) within the guide (2). In this figure the shutter is free to move within the guide. The shutter locking system is inserted into the guide and consists of two parts: one mobile (3) and one fixed (4). The mobile part in sliding brings the fixed part into contact with the roller shutter, taking it to abut with the external gasket (J). On the fixed part (4) there is a projection (5) which, in the closed position, rests in the special housing (6) created in the roller shutter.

Figure 12 in plate 4 shows the system illustrated in figure 11 of plate 4 in the closed position. Note the roller shutter (11) abutting with the gasket (12) in guide (13). Further note the fixed part (8) of the closure system which abuts with the shutter (11) with projection (10) in its special housing. The mobile part (9) by sliding causes the fixed part (8) to abut with the shutter.

Figure 13 in plate 5 represents the section of the roller shutter within the guide equipped with locking system. Note the roller shutter (1) set in the guide (3) with the related gaskets (2) (5). The guide (3) houses the locking system (4) which brings the shutter to abut with the external gasket (2). Figure 14 in plate 5 represents the profile of the roller shutter (6) on which a housing (7) is created for the projection created on the locking system with view to keeping the shutter fixed within the guides. Figure 15 in plate 6 represents a variant of the deformation created on the roller shutter profile. This variant is represented by the side cap (2) created with special interlocks (6) in such a way as to be assembled at the extremity of the roller profile (1). The cap is formed in such a way as to have a plane (4) created between two curved surfaces (3) (5) which follow the curve of the profile. On the profile (1), also note the co-extruded gasket (7) which improves air seal at the sill. Figure 16 in plate 6 represents the side cap (9) described in figure 15, plate 6, assembled with the roller profile (8). The figure also shows the co-extruded gasket (10) which improves air seal at the sill. La figure 17 in plate 7 represents the insulation system also illustrated in figure 10 of plate 3, with a variation. The figure shows the possibility of inserting a mobile gasket (3) also in the zone between the roller shutter and the window (1). Thanks to movement system (4) the gasket can be shifted from open position (2) to closed (3)
