Hot insulating window

The invention relates to a window, in particular a multiple pane, the at least two glass panes, which are separated on their periphery by a spacer, the is surrounded by an impermeable seal in such a way that a closed air space remains between the two panes, and is equipped with a heating conductor system. The spacer preferably consists of a metal profile. The heating conductor system is formed by resistors, which are arranged on the inner surface of at least one of the glass panes. These resistances can be known per se Way of a continuous layer of any conductive transparent material, for example gold or tin oxide, be educated. However, they can also be in the form of individual resistors, for example in the form of strips or Threads using Enailleleiterii, in particular on The basis of silver, which is applied in screen printing and burned in at high temperatures.

Of course you can't have them on the outside provide because the security requirements the use forbid improtected electrical circuits and in the event continuous layers that would also be too exposed to abrasion.

The resistances are generally via Sajamel rails supplied, which in the screen printing process either at the same time as the heating conductor and in the same ¥ iron or in In the case of a transparent layer can be applied before the manufacture of the same.

According to the invention, each bus bar is deposited ge ^ ^ r enüb the spacer d _# h. arranged with respect to the mounted window so that it is located between the glass pane and the area of the spacer which rests on the pane. In addition, the busbar protrudes outward beyond the area of this spacer in the direction of the window edge, at least in the area which is provided for the attachment of the power connections. These power connections are formed in a manner known per se by conductive wires or preferably contacts or tongues, which are expediently welded or attached in the interior of the window in the area of the seal in such a way that they are not too vulnerable. This feature allows the busbars to be concealed in a smaller frame and improves the appearance of the window, but at the same time allows the supply wires to avoid crossing the spacer zone. This crossing is always difficult and affects the seal to such an extent that one has to avoid laying the wires side by side and, for example, letting a conductor emerge at each corner of an equal diagonal of the window.

In contrast, according to a further feature of the invention, it is also possible to use at least one of the Saiamelle leaders the circumference of the window outside of the heatsealing band up to to relocate near one end of the other sainmelle ladder.

Ms «can also connect the two supply lines to two Connect neighboring places *.

According to a preferred Aüsfulirnjngsform according to the invention nefiPien the laid on the Ürafatig the window Sämmelschieneii like a & n entire circumference with the exception of at least two interruptions, which are preferably vorgeselien at the ends of a diagonal * - piping solution allows, for example, in a particularly simple a series-parallel assembly " Of course, it is possible to provide a larger number of vök interruptions * either for the purpose of the same assembly or for other reasons.

In the case of a metallic spacer, it goes without saying that it must not short-circuit the heating conductors. For this purpose, the estnümelschienen can be protected by an insulating cladding, but for reasons of difficulty in making the sealing, the spacers are appropriately insulated or simply opened Italian electrical interruptions are provided. According to the invention, this can be achieved by using, as is known in FIG. 1, the use of an insulating material to combine the four professional elements that form the branches in the case of a fetister.

The invention is to be described in more detail below with reference to the drawings be explained, tucks show in ..

The Saramel rails 3 νκιά. 4 consist of a sliding enamel on the basis of iron silver and are applied by screen printing »They run over the entire circumference of the window with the exception of the interruptions at 5" and 6 ₉ which are at the ends of a diagonal *, they are through layer 2 only connected on two opposite sides.At least one of the interruptions can be enclosed by two areas which are directed towards the edge of the window, in order to facilitate the welding of connecting wires or the attachment of connecting terminals 7 and those here in the form of two cylindrical terminals are indicated, "The arrangement has the advantage of facilitating assembly and enables good tightness." Select interruptions 5 and 6 in such a way that the passage of the connecting lines is facilitated his, for example, to provide them near the window sash,

It is also possible to provide three or more interruptions, for example to supply all types of connected devices «

Fig. 2 shows schematically !! a window metailisehem spacer "- The inserted between the two glass panes 1 and 9" spacer is constructed _s that it can not short out the heating conductor To this Zw @ ck are the various elements of the profile 10 at the corners in accordance with the invention by means of.

The shape of the obtained compound results from -Fig '4 _e' The profile has approximately trapezoidal cross-section, and rests on each disk over a range of caj 3 mm width. The busbar 3 is located between the disk 1 and

the Aüflagebereich of the profile, but their width is of the order of 5 mm North Ting _s such that it extends slightly to the edge of the window. It is widened in the area of the connections 7 in the corner of the window, where the profile is interrupted and replaced by the angle piece 11 with a narrow cross-section. The window edge is filled with a sealing filler compound 12, for example a polysulfide adhesive, and is preferably protected by an adhesive tape 13. The busbar 3 can in the same way extend somewhat into the interior of the window, as the drawing shows _{y in} order to avoid any risk of damage to the heating conductor by the profile.

In the case of a heating conductor in the form of a transparent precipitate, the position of the busbars avoids recognizable any contact of the precipitate with the filler 12 in such a way that there is no risk of the heating layer becoming detached.

In another embodiment, the metallic spacer be coated with an electrically insulating varnish. .

In addition, the glass pane 9 can be coated with a conductive deposit, for example a semi-reflective layer be occupied, but it is then necessary to this side of the spacer or at least the heating layer isolate"
