Definitions
- the present invention relates to a double glazing with built-in sunshade for building openings.
- the building openings in particular windows and doors, are today preferably provided with double glazings, which in their interior have an evacuated chamber which is intended to improve the thermal insulation of the building opening.
- double glazings which in their interior have an evacuated chamber which is intended to improve the thermal insulation of the building opening.
- the law also requires that such solutions be used in construction, and the economic benefits are obvious.
- the problem addressed by the present invention concerns the more or less strong shielding of the total solar radiation, which also includes the infrared and the ultraviolet radiation beyond the visible spectrum. It is therefore not only about the infrared radiation whose shielding the conventional double glazing for windows mainly aim, but to the whole spectrum of solar radiation, which concerns both the problems of thermal insulation (ie energy savings in winter and summer thanks to less heat transfer or lower heat transfer) as well as the harmful ultraviolet rays and the radiation in the visible spectral range, which bring problems of glare and visual screening with it.
- a so-called sun blind (slat blinds) made of pivoting individual slats is attached to the outside of the double glazing, or in the interior of the double glazing to regulate the degree of darkening.
- the operation of the sun blind can be done from the outside by means of an electric motor or by hand.
- the arrangement of the electric motor in the interior of the double glazing is already known, which has the purpose to create better conditions for the tightness of the interior of the double glazing.
- the second mentioned system which is also known, is applied in practice for many years, is the application of a sunscreen on one of the outer panes of double glazing, which is capable, in addition to the radiation in the visible spectral range, the infrared radiation and possibly also to retain the ultraviolet radiation.
- a sunscreen on one of the outer panes of double glazing, which is capable, in addition to the radiation in the visible spectral range, the infrared radiation and possibly also to retain the ultraviolet radiation.
- Such films are commercially available today in a variety of types with specific shielding properties; such are referred to as CP film and are manufactured by various companies, such as the well-known company 3M.
- the different types of film are characterized, for example, by their permeability to the different types of radiation, the reflection of the types of radiation, the absorption of the radiation, the transparency, the light reflection, the transmission of ultraviolet radiation and the measure of the total solar energy retention, all data in percent.
- Such films are preferably used to darken car windows, and the wide variety of types with a variety of properties allows adaptation to very specific needs.
- the present invention aims to eliminate the disadvantages of said known solutions and proposes an evacuated double glazing in which the transparency properties of the window can be adapted to the environment and the current weather conditions by using sunscreen films, but which are protected from external influences are protected against mechanical stresses.
- the proposed solution should be less burdensome in terms of cost of the sunscreen of any type.
- the inventive novelty is that a roll-up blind is installed in the interior of the double glazing, which can be moved from the outside, and by means of which the whole window area of the double glazing can be darkened, the permeability for the types of solar radiation between 0% and 100%.
- the roll-up shade can cause virtually all solar radiation to pass through, or be retained, reflected, and / or absorbed due to its solar absorption characteristics, depending on the specific properties of the material from which the shade is made.
- the shade provided in the present invention which is made of a thin woven fabric or preferably a thin sheet of plastic material having specific properties for transmitting different wavelengths of solar radiation, can be wound on a small-diameter roll so as to be inside the double glazing can be accommodated, even if the whole blind is wound up on the roll (ie with the blind raised).
- the blind is housed inside the evacuated double glazing, it is protected from all mechanical stresses (influences of wind and weather, blows, etc.) that would otherwise ruin it within a short time.
- a considerable further economic Achieve advantage namely because the films do not need to be glued to the glass and therefore no longer need to be provided with an adhesive layer during their production (with an adhesive that is activated when applying the film).
- the films can therefore be thinner and thus less expensive to choose, and eliminates the delicate process of sticking the films to the glass sheets (the formation of air bubbles is known to any person skilled in the art).
- the main advantage of the inventive solution is that the blind can be wholly or partially wound up on a roll, whereby the shielding effect can be fine adjusted according to the requirements.
- a double glazing traditional type is shown, formed by a rectangular frame 1 on which a glass sheet 2 and 3 is mounted absolutely sealed on both sides (better seen in Fig. 2, in which a section perpendicular to discs 2 and 3).
- a sufficiently strong vacuum prevails in order to ensure the values of the thermal insulation expected from double glazing.
- the frame 1 is in turn incorporated into a support structure and fastened in the usual way.
- the present invention provides that a blind which can be wound up on an externally operable roller 5 is provided in the interior 4 of the double glazing.
- a basic feature of the present invention is that the blind allows the entire aperture to be darkened with a transmittance of 0% (corresponding to a fully darkened window) to 100% (totally uncovered window) of solar radiation.
- the shutter 6 must be very thin (of the order of a tenth of a millimeter) to be wound on the roll 5 without enlarging its diameter, and must also have precisely certain transmittance characteristics for the different wavelengths of the Have solar radiation.
- the Selection of solar panel transmittance 6 depends on the intended application, depending on whether the emphasis is on thermal insulation, privacy, eliminating the harmful effects of ultraviolet radiation, etc. The appropriate choice is left to those skilled in the art, a large number of plastic film types available to achieve the desired insulation effects. On such types of film is to come back in the following.
- the blind 6 according to a first preferred embodiment of the present invention can be formed from a thin fabric with low light transmission ( whereas ordinary or suitably material treated tissue can be used).
- the venetian blind is made of a plastic material having certain transmittance properties for solar radiation of different wavelengths.
- Such films commercially referred to as CP films, are made of polyester (PET), which are very thin and extremely transparent, and are treated in such a way that they are through-dyed and / or impregnated against ultraviolet radiation. These are treatments in which noble metal layers are vapor-deposited or sprayed onto the substrate (according to a so-called cathodic powder coating method).
- the products thus obtained are suitable as protective films against solar radiation and heat, and their physicochemical properties can be taken from the data sheets known to the person skilled in the art, in which also the information about permeability to the visible light is given (which is the radiations the wavelengths from 380 to 780 nm) as well as the transmittance for the entire solar radiation (from 280 to 2500 nm wavelength, including the infrared radiation), and the ultraviolet radiations (from 190 nm to 380 nm wavelength), the absorption of the types of radiation and the transmittance of ultraviolet radiations. All of this information is available to those skilled in the art.
- the novelty of the present invention is that thin blinds of this kind, in particular the various types of suitably treated polyester films, are used as blinds which can be wound up in the interior 4 of the double glazing on a roll 5, these foils being protected against all external influences without having to be glued to a glass surface. This allows at any time a raising or closing of the blind to adjust the protective effect of the building opening to the outside currently prevailing conditions.
- the blind 6 may be formed of a polyester film, which certain properties with respect to general reflection of solar radiation or in particular the reflection of the radiation in the visible spectrum - to achieve the privacy - or restraint of the ultraviolet radiation, or the reflection of at least 32% of the incident solar energy, or preferably even at least 90% thereof.
- the shutter 6 need not be glued to the glass surface in all their forms of training, which also neither a layer of adhesive - which would increase the cost of production - nor a very delicate and costly gluing operation is needed.
- the movement of the winding roller 5 can be accomplished manually by means of a crank, as already known from practice and therefore not shown in the figures, or can be done by means of an electric drive motor 7, which is housed in the interior 4 of the double glazing.
- the electric drive motor becomes in the take-up roll 5 self-installed.
- Such motors may be formed with an internal stator, wherein the external rotor is formed by the roller itself.
- the solutions with a arranged in the interior 4 of the double glazing engine compared to solutions with drive from outside the said double glazing fewer problems of the seal with it and are therefore preferable.
- a magnetized rod 8 which acts on a ferromagnetic rod, which is attached to the lower edge 10 of the blind 6.
- the winding roller 5 must of course be subjected to a torsional moment, which is exerted by a torsion spring 11, for example, and which attempts to wind the blind 6 on the roller 5.
