Definitions

• the present invention relates to double-glazed windows or insulation glasses provided with an inner blind or plisse curtain, where the insulation glass is provided with a spacer element or spacer where the spacer may comprise a protruding part with the shape of a rail or wing .
• An insulation glass is an arrangement with two or more par- allel or mainly parallel layers of glass which are kept in a mutual distance from each other by means of a spacer element or spacer .
• the distance between the glass layers in an insulation glass is normally from about 6 mm to about 30 mm.
• the insulation glass operates in such a way that the gap between the glass layers has an isolating function . Therefore, it is important that the distance between the glass layers is of such extent that no convectional currents are formed in the gas between the glass layers .
• the insulation glass also must have a certain strength to withstand physical challenges such as impacts , shock, thermal variation and others , the glass in an insulation glass can not exceed a certain thickness .
• the weight of several glass layers will increase the total weight of the window . It is unusual with more than three glass layers (even if it is possible) , which enables two insulating cavities to be created between the glass layers .
• the glass layers in an insulation glass are kept in position by a spacer, where the glass is fixed to the spacer by means of a sealing means such as a filler .
• a sealing means such as a filler
• Such filler can be silicone, rubber, plastic or generally a polymeric material .
• the sealing means in addition to fixing the glasses to the spacer, functions as a barrier between the atmos- phere and the gas in the gap between the glass layers of the insulation glass .
• the inner of the gap or interspace in connection with the sealing means or as a separate arrangement, with a moisture removing desiccant .
• the gap between the glass layers in an insulation glass may be provided with a particular gas or gas mixture which is different from air, for example a gas mixture with an increased content of carbon dioxide .
• the ther- mal insulation may to some extent be controlled be regulation of the composition of such gas mixture, as different gases have different thermal conductivity .
• the insulation glass it is possible to provide it with a glass layer which automatically changes colour depending on how much light that reaches the glass layers . It is also possible to provide the glass layers with a metallic alloy which for example can contain precious metals such as gold. Such alloys are normally supple or soft and will normally be very vulnerable to mechanical wear . It is normal to arrange such layers in the interspace between the glass layers in an insulation glass . Optical adjusting or regulating layers can also be provided as separate layers such as foils or plastic sheets .
• an insulation glass which has one or more of the characteristics mentioned above .
• a blind or plisse curtain Normally there will be such blind or plisse curtain in an insulation glass .
• blind or plisse curtain may come in contact with or scrape against the inner glass plate on the glass layers of the insulation glass, which over time can lead to scratches on the window, or the added metal or plastic layer for adjustment or the light characteristics of the glass can be scratched or scored by the movements of the blind or plisse curtain .
• the obj ect of the present invention is to provide an improved insulation glass where this problem is minimised or eliminated.
• This obj ect is obtained by provi- sion of an insulation glass where the insulation glass is provided with a spacer, where the spacer may comprise a protruding part designed as a rail or wing provided with a sliding and/or noise absorbing element and/or where at least one or all of the inner inwards parts of the insula- tion glass are provided with such sliding and/or noise ab- sorbing element .
• Such sliding and/or sound absorbing elements preferably made in a polymer composition such as a plastic material (for example polyethylene, polyvinyl, polyurethane) , silicone or a silicone based material or rubber .
• Fig . 1 shows the structure of a common insulation glass pane without a blind or plisse curtain .
• Fig . 2 shows the structure of a common insulation glass pane with a blind or plisse curtain and with a rail or wing in connection with or integrated with the spacer .
• Fig . 3 shows the structure of a spacer according to the invention with a sliding and/or noise absorbing element ar- ranged in a groove in the rail of the blind or plisse curtain .
• Fig . 4 shows an alternative embodiment of a spacer according to the invention with a sliding and/or noise absorbing element arranged on the rail of the blind or plisse cur- tain .
• Fig. 5 shows an alternative embodiment of the design of an insulation glass where the position of the blind or plisse curtain is controlled by projections of a layer on one or both of the glass panes of the insulation glass .
• FIG. 2 it is known to provide a spacer in an insulation glass with glass panes 1 and sealing compound 3 with a wing 4 for a blind 5.
• the insulation glass may also have one or more layers 6 of an optically manipu- lating material on one or both of the glass panes facing the blind 5. Normally, there is only such layer 6 on one of the glass panes .
• the profile frame or spacer 2 may be provided with more than one wing 4 for the curtain or blind 5 , for example to prevent the blind from getting in contact with one of the glass panes 1.
• the spacer will normally be provided with one wing 4 for the blind 5. The disadvantages with such design have been explained above .
• Figures 3 and 4 shows the spacer design according to the present invention, where the guiding rail or wing 4 is provided with a sliding and/or noise absorbing element 7 which prevents scraping and undesired noises such as shrieking as explained above .
• the above mentioned element 7 can be arranged in a groove 8 being provided on the guiding rail 4 of the spacer 2.
• the element 7 is mechanically connected to the guiding rail on the spacer 2 without the use of glue or other adhesive agents .
• the sliding ele- ment 7 can be provided as an elongate lining having a circular cross section and being pressed into the groove 8 on the guiding rail 4.
• the sliding element 7 can have an oval cross section where a longitudinal slit is made for arranging the lining onto the guiding rail 4 in an encasing manner .
• FIG. 5 An alternative embodiment of the invention is shown in figure 5 where the spacer as provided without a guiding rail, but where the contact between the blind and the glass panes 1 and/or layer 6 is prevented by means of protrusions 9 di- rectly arranged on the glass panes 1.
• the blind 5 is wedged between the guiding rails 4 (if there are more than one of these) or the sliding material 9, it is possible to employ the solution according to the invention with multiple guiding rails 4 or sliding material 9, for example if the blind 5 has a constrainedly guided movement by means of for example a motor connected with guiding straps and/or guiding lines for the blind/curtain 5 (not shown) .
