Abstract
A thermally and acoustically insulating double glazed vehicle window, particularly an automobile side window, is formed from two sheets of glass (1, 2) united by a sealing bead (3) and having different thicknesses. The thicker sheet (1) is on the outside, the thinner sheet (2) on the inside. <IMAGE>
Description
WINDOW FOR A VEHICLE
The present invention refers to a thermally insulating window for a vehicle, in particular to an opening side window for an automobile. formed as double glazing from two sheets of glass united by means of a spacing bead which follows the entire periphery of each sheet.
Said spacing bead is made having various configurations and can also be used to contain materials capable of absorbing humidity within the interstice. so as to avoid undesired phenomena of glass fogging.
Thermal by and acoustically insulating double glazing is widely used in the building construction field, as it permits considerable advantages in the thermal and acoustic insulation of the internal environment.
Said type of glazing can also be used on vehicles with the same objects of thermal and acoustic insulation, thus allowing greater comfort internally.
For evident safety reasons, said type of glazing is preferably used in opening side windows of automobiles.
Use in an automobile is known from the state of the art.
German Patent application No. 3.517.581 describes glazing for automobiles comprising two sheets of glass in which the inner sheet has a surface greater than that of the outer sheet, in particular along its short sides and along the upper edge, in order to favour the sealing of the glass itself and its running along the guides.
French Patent application No. 2.609.946 describes glazing particularly suited to be used on an automobile, due to its aesthetic aspect and the ease with which it can be cleaned.
One of the problems which has up to now slowed down the use of such glazing on a large scale consists in the fact that; in Order to obtain adequate insulating characteristics, both thermal and acoustic, the thickness and therefore the weight of the glass were not compatible with the necessity of reducing the overall weight of the vehicles.
A further problem consisted in the fact that, as said glazing was required to correspond to the safety regulations in force, it was necessary to use thicknesses of glass which, after having been tempered, presented a fragmentation pattern corresponding to said safety regulations
The latter problem was overcome by using a glass having a sodium/aluminum composition in the place of the normal and usual glass having a sodium/calcium composition.
Said glass has the characteristic that, in spite of being extremely thin, it shOws, thanks to a chemical tempering process, a fragmentation pattern which corresponds to safety regulations, so that it is possible to produce sufficiently lightweight glass for automobiles.
However, the reduction of thickness, consequent on the necessity to reduce weight, caused a reduction in thermal and acoustic insulation.
The object of the present invention is therefore to overcome the above-mentioned problem.
This object is obtained by means of a special placing of the sheets of glass, and more specifically using two sheets of glass having different thicknesses.
In particular it has been found that, by placing the sheet of glass having a greater thickness towards the external environment and the sheet of glass having a lesser thickness towards the internal environment, the acoustic insulation is considerably improved, thus giving an improved comfort to the inside of the vehicle.
The ' capacity for thermal insulation is advantageously obtained by depositing, on one or both sheets of glass, thin reflective and antisolar layers containing an oxide or metal, in such a way as to control the flow of energy and therefore to obtain good insulation conditions both in summer and winter.
The thin layers themselves are furthermore electrically conductive and are capable of increasing the already consistent effect due to the reduction of the energy exchange coefficient, permitting the de-misting of the glass if a voltage differencial is applied.
Object of the present invention is therefore an insulating glass for vehicles, in particular an opening side window for an automobile comprising two sheets of glass joined one to the other and at the same time spaced one from the other by a bead which extends along the whole periphery of the glass, characterized by the fact that the two sheets of glass have different thicknesses and by the fact that the outer sheet of glass has a greater thickness than the inner one.
Further characteristics and advantages of the invention will be clear from the following description, given in a purely exemplificative and not limitative manner and with reference to the single figure attached, which shows a section view of a side window for automobile.
In the figure an external sheet of glass 1 is connected to an internal sheet of glass 2 by means of a spacing bead 3 which also has the function of sealing an interstice 4 between the two sheets.
Suitable locking and sliding systems, not shown in the figure, serve to allow the movement, which is generally from up to down and vice versa.
According to the present invention, the external sheet 1 has a thickness greater than the internal sheet 2.
Naturally the effects of the present invention also extend to models which permit the performance of similar uses using the same inventive concept.
Claims (6)
1. A window for a vehicle, formed as double glazing comprising two single sheets of glass united one to the other and spaced one from the other by a bead which extends along the whole periphery of the glass, characterized by the fact that said sheets of glass are of different thickness.
2. A window for a vehicle according to claim 1, characterized by the fact that the external sheet of glass has a thickness greater than the internal sheet of glass.
3. A window for a vehicle according to claim 1 or 2, characterized by the fact that the sheets of glass have a sodium/aluminum composition.
4. A window for a vehicle according to any one of the preceding claims, characterized by the fact that the sheets of glass are chemically tempered.
5. A window for a vehicle according to any one of the preceding claims, characterized by the fact that on one or both of said sheets of glass are deposited thin layers to increase the degree of summer and winter thermic insulation of the glass.
6. A window for a vehicle, in particular an opening side window for an automobile. substantially as described above with reference to the drawing.
