Description of the invention

This invention relates to an aluminium framework intended for the manufacturing of doors or windows, which is applied to an opening of a building's door or window, preferably comprising one door with two sliding panels (A) (B).
This invention is comprised of, at least, one fixed rim (1) and only one or several stationary or movable panels (5), which are inserted into the fixed rim (1) and laterally moved in parallel or perpendicular plans. The panels (5) can be provided with manual or motorized movement and be comprised of panels made from single-, double- or triple-glass or other type of material. The panels (5) include a central stud (6) and/or a reinforcing central stud (7), as illustrated in Figure 9, which can have profiles with a visible thickness of 18 mm in one of the edges. In the other edge, it can be provided with either a puller with flap (9) or a flapless puller (10).
The fixed rim (1) is perimetrical and usually comprised of a rectangular or square-shaped aluminium hard frame. All sides of the fixed rim (1) are formed by the same profile and they are attached to each other by any means known in the art. It is provided with rim covers (3,11) in one edge, as illustrated in Figure 9, and sealants (4) in the central area.
In all of the aforementioned cases, the fixed rim (1) profile to be used is always the same. These panels can have a thickness ranging from 36 to 100 mm of total width. The fact that this invention is modular will allow the panels (5) to be manufactured with a nominal thickness within a size interval as mentioned above. The variation of thickness is made possible by changing only the polyamide profiles (13) which create the thermal break and join the different profiles forming the fixed rim (1). This invention also allows the panels (5) to be manufactured and used with weights up to 2000 kg per linear metre.
The panels (5) may be manually or automatically operated. The profiles forming the fixed rim (1) were developed so as to enable the automated sliding of the panels (5), without the need to add any other profiles to the system.
In order to cause the panels (5) to be moved without a huge effort, an aluminium profile was specially developed to this system, in which bearings were incorporated. This profile is known as sliding rule (12) and is accommodated in the lower section of the fixed rim (1), in slots which are specifically arranged for that purpose. The number of bearings to be used in each sliding rule is directly dependent from the weight of the panels (5).
The locking system (2) of the movable panels is incorporated into the aluminium profiles of the fixed rim (1) and allows the number of locking points to be arranged according to the size of the movable panels. The locking system (2) is a multipoint one, so the number of locking points is adjusted to the height and weight of the panels (5). Once assembled, the locking system has no visible fixing elements, which is a distinguishing characteristic as regards the current state of the art.
This invention further comprises a pneumatic sealing system between the panels (5) and the fixed rim (1), when the window/door is closed, with which the protection against wind and water is substantially improved, as well as the acoustic performance. Inside the fixed rim (1) there is an air chamber (14) which was specially developed for this purpose, since it expands in order to adapt itself to the inner surface of the fixed rim profiles and to the panel profiles, being filled with air (15) by means of a mini compressor, when the window/door is closed. When filled with air, the chamber expands until contacting with the panels (5), thus making the sealing between the fixed rim (1) and the panels (5) to be greater than the one that was previously possible. The panels (5) have an active acoustic absorption integrated system, which allows the noise pollution coming from the outside of the building to be reduced, and which can be adjusted according to the location and the type of noise to be mitigated or eliminated. In effect, there is a receiver (16) placed in the outer section of the panel (5), turning it into a big 'microphone' which is connected to a wave generator, processing the information received and generating counter-phase sound waves (19) which are then sent to a sound wave emitter (17) which is attached to the inner section of the panel, causing the latter to act as a large sound column. The result of the addition of the entering sound waves to the counter-phase generated waves is zero, which can be translated into a nullification of the sound coming from the outside environment.
The framework system which is the object of this invention allows the movement of the stationary/movable panels (5) to be motorized, with no need to replace any of the profiles from the fixed rim (1). In the fixed rim (1) profile, a track was created in order to hold and guide a "traction carriage" which fits in the panel (5). The said "traction carriage" (20) is fastened to a belt (21) which is inserted into the upper profile of the fixed rim (1) and runs over two pulleys (22). In order to insert the pulleys (22) into the profile of the fixed rim (1), a machining is performed thereof. One of the said pulleys (22) is connected to an electric motor which, when actuated, causes the carriage (20) to move, and consequently, the panel (5) also moves.
Rainwater's elimination on windy days is a problem affecting the frameworks in general. For this particular framework, a water extractor (23) was designed which solves that problem. This innovation consists of a component which is fastened to the holes performed in the fixed rim (1) in order to eliminate rainwater. These components are provided with blades which freely rotate around a shaft. When in the presence of wind, the blades will rotate and the water will be extracted from the inside of the fixed rim (1) in a more efficient way than with the prior state of the art. The sliders (24,25), which are fitted into the lower and upper sections of the panels (5), remaining fastened to the four corners thereof, will promote the movement of the panels (5) and neutralize the resulting noise, thus providing for an effortless, smooth and silent sliding.
The other purpose of this component is to eliminate the noise when the movable panel is being moved. The noise is similar to the one heard when travelling in a train and it passes over the rail joints. The same happens in the case of the sliding frames. The problem occurs while the movable panels are being moved and whenever the lower section of the panel initially touches the bearings, a slight stroke is heard. The noise is eliminated thanks to a ramp track (26) which was arranged in the sliders (24,25), promoting a smooth contact between the bearings of the sliding rule (12) and the lower section of the movable panels. In addition to the use of sliders, a brass bar (27) is also used, which is fastened to the lower section of the panel. The brass bar (26) is aimed at avoiding wear of the aluminium profiles forming the panels (5).
