Abstract

This new system allows for at least 12 different technical installation schemes and is based on 13 profiles: eight aluminium profiles manufactured with thermal breaks and double colour, a single aluminium profile acting as the latch cover for the movable wings, and four profiles made entirely of polyamide, which are two structural security and thermal break profiles (20 fig. No. 1) and (19 fig. No. 2), a trim profile for sliding wings (21 fig. No. 3), and a run limiter profile for the sliding wings (22 fig. no. 1). These thirteen profiles include configurations and a specific structure for the system, specifically conceived for large embrasures, which can include adjacent windows, intercalated, or not, with fixed upper, lower or side panels, with door and window frameworks, which can be movable or fixed and simultaneously tiltable. The structural profiles are equipped with a track and space for installing an exterior solar blind and space for installing a mosquito blind between the solar blind and the windowpane.

INDOW SYSTEM ITH THERMAL BREAK PROFILES

DESCRIPTION

The present Invention Patent application involves a system of aluminium frameworks specifically conceived for installation in embrasures with drop portals and windows in buildings.

The known frameworks systems for drop window embrasures are mounted with whole profiles, that is, internally and externally the same aluminium profile is visible, thus there is always the possibility of interior humidity condensation when there are significant thermal differences between the internal and external temperatures. The exterior colour of the aluminium framework is obligatorily the same as that of the interior because the anodization or coating is the same for the entire profile.

The aluminium framework system for drop windows presented herein was technically studied to be applied to embrasures with broader than usual spans and to simultaneously resolve condensation and single colour problems. Accordingly, various structural solutions were studied and tried with new profiles for installing drop windows (fig. 1) with various conditions and options, including: single or double with two movable panes or with only one, with or without tilting and with or without with fixed side panels or fold panels.

This new profile system resolves the above-mentioned problems via specifically studied applications which translate into a series of technical solutions, the assembly details for which are included figures number 1, 2, and 3 and (fig. no. 4 to 12 ); however, the versatility of the profiles that compose this new system also allows installation of any other traditional structure, it provides architects with the necessary creative freedom to resolve short-term decorative problems, based on new types of aluminium structures. By making use of the structural connection profile, these new profiles also permit intermediate installations with slight variations in terms of the presented assembly details, always maintaining quality in terms of the technical characteristics of acoustic and thermal insulation with added decorative innovation via use of double colour for the structural profiles.

This new system mainly consists of thirteen profiles, eight of which aluminium profiles manufactured with thermal breaks (fig. no. 14 to 21 ), a single aluminium profile which is a latch cover for the movable portal and window panes (fig. no. 13), and four more profiles entirely made of polyamide (fig. no. 22, 23, 24, and 25 ): two structural security profiles and thermal breaks (fig. no. 22 and 23), a trim profile for the upper/lower movable parts (fig no. 24), and a damper profile for the movable panes of the drop windows (fig. no. 25). The eight thermal break profiles (fig. no. 14 to 21 ) are single profiles the contours of which and structure were specially studied and designed for this system. Each is manufactured with two aluminium profiles, joined with two trapezoidal-shaped polyamide profiles, symmetrically positioned, attached to the aluminium profiles via special machine during manufacture. The profiles manufactured using this process are able to disperse thermal differences between the two aluminium profiles, internal and external and are also high resistance profiles capable of supporting expansion and contraction caused by the thermal differences. When applied in embrasures of high rise buildings or in large embrasures of normal buildings, allow the flexibility necessary to resist strong winds without breaking or damaging the attachment structure.

This new drop system, as I have mentioned, allows installation of adjacent fixed window-panes in any of the window or portal sides and the movable panes are also tiltable, allowing complete cleaning of glass from inside the building, and when horizontally semi-tiltable, they allow for complete airing out of the interior space.

The profiles of this new system have the specific technical advantage of being larger than normal; they are longer and have larger volumetry than the traditionally used profiles. This is why they allow for construction of larger embrasures for drop portals or windows that can be installed in continuous facing of adjacent windows or intercalated with fixed window-panes, therefore constituting a framework system structurally appropriate for the facades of high rise buildings or any type of building located in areas subject to cyclones, humidity or tornados.

This profile system also includes a technical innovation consisting of the use of two colours, making the profiles suitable for modern construction requirements in residential zones, which generally must comply with an obligatory colour or tone for the exterior of the buildings within the residential area. With traditional frameworks, the interior colour of the portals and windows must be the same as the exterior colour; however, in terms of the profiles of this new framework system, because they are thermal break structural profiles, the interior colour may be different from the exterior colour. All that is required for this is that during manufacture the profiles be anodised or coated with a different colour, the exterior colour being that of the obligatory project colour and the interior with a warmer or cooler colour in accordance with the use or decoration of the interior space.

The profiles specially suited for the installation of movable or fixed window- pane frames were designed to permit installation of double glass of up to 24 mm. They are equipped with exterior tracks and spaces for installation of solar blinds. Between the solar blinds and the windowpane a space was incorporated for installing a mosquito net type blind.
