Opfindelsen angår en alarmrude med flere lag glas, hvor et yderste glaslag består af forspændt silikatglas, hvilket glaslag på den udvendige overflade bærer en elektrisk ledende, sløjfeformet bane af fast-5 brændt, elektrisk ledende emalje, og hvor glaslaget er fast forbundet med de andre lag på siden modsat sløjfebanen via en afstandsramme eller en transparent klæbefolie, i det mindste langs de to nærmest sløjfebanen beliggende kanter.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a multi-layer glass alarm pane in which an outer layer of glass consists of prestressed silicate glass, which bears on the exterior surface an electrically conductive, looped web of solid-burned, electrically conductive enamel, and wherein the glass layer is firmly connected to the other layer on the side opposite the loop path via a spacer or transparent adhesive film, at least along the two edges closest to the loop path.
10 Der kendes forskellige alarmruder, hvor et for spændt silikatglaslag på overfladen har en fastbrændt ledende bane af en elektrisk ledende emalje. F.eks. kendes fra NO B 133.031 at anvende en alarmrude bestående af et enkelt lag af hærdet glas, hvor glaslaget langs en 15 del af sin omkreds har en elektrisk ledende linieformet bane fremstillet af en metalpulverholdig glasfritte ved fastbrænding til glaslagets overflade under hærdningen af glaslaget, og hvor banen er placeret på glaslagets kant eller så tæt ved denne, at den skjules ved glasla-20 gets indramning. Der omtales endvidere en udførelsesform, hvor den beskrevne enkeltglasrude er sammenbygget med en rude af maskinglas, så de sammen danner en termorude, hvor det forspændte glaslag er placeret på den side af termoruden, der vender bort fra det rum, der 25 skal beskyttes.10 Various alarm panes are known in which an over-tensioned silicate glass layer on the surface has a burnt conductive path of an electrically conductive enamel. Eg. it is known from NO B 133.031 to use an alarm pane consisting of a single layer of tempered glass, wherein the glass layer along a portion of its circumference has an electrically conductive linear shaped path made of a metal powder-containing glass frit by burning to the surface of the glass layer during the curing of the glass layer and the web is located on the edge of the glass layer or so close to it that it is concealed by the framing of the glass layer. Further, there is disclosed an embodiment in which the single glass pane described is built together with a machine glass pane, together forming a thermal pane where the biased glass layer is located on the side of the pane facing away from the space to be protected.
I en flerlags alarmrude, som kendes fra DE B 1.278.292, er den ledende bane anbragt i glaslagets kantområde parallelt med en kant, og banesløjfen kan være anbragt både på glaslagets frie udvendige side og på 30 modstående sider på alarmrudens øvrige lag. Ved denne såvel som i de i ovennævnte norske fremlæggelsesskrift angivne udførelsesformer kan der forekomme tilfælde, hvor de ved brud fremkomne glasbrudstykker på de beskrevne steder fastholdes af et nærliggende lag og/eller 35 fastholdes af den omsluttende ramme, så der ikke er garanti for en sikker adskillelse af den ledende bane.In a multi-layer alarm pane known from DE B 1.278.292, the conductive path is arranged in the edge area of the glass layer parallel to an edge, and the path loop can be placed both on the free outer side of the glass layer and on 30 opposite sides on the other layers of the alarm pane. In this embodiment as well as in the embodiments specified in the above-mentioned Norwegian disclosure, there may be cases where the broken glass fragments at the described locations are held by a neighboring layer and / or 35 are retained by the enclosing frame so that there is no guarantee of a safe separation of the conductive path.

Det er et sigte med opfindelsen at tilvejebringe en alarmrude af den omhandlede art, hvor der med sikkerhed afgives et ønsket signal i tilfælde af rudens ødelæggelse, og hvor ruden er udført således, at dens funk-5 tionsevne ikke påvirkes selv gennem længere tid, uden at dette dog medfører en forøgelse af fremstillingsomkostningerne .SUMMARY OF THE INVENTION It is an object of the invention to provide an alarm pane of the kind in question, where a desired signal is safely delivered in the event of the pane's destruction and where the pane is designed so that its functional ability is not affected even for a long time without however, this results in an increase in manufacturing costs.
Dette opnås ved alarmruden ifølge opfindelsen ved, at den elektrisk ledende sløjfeformede bane er pla-10 ceret i et hjørneparti af det forspændte silikatglas i en sådan afstand fra glaslagets kanter, at i det mindste dele af banen sidder inden for lysåbningen, dvs. uden for det kantområde, som senere dækkes af indbygningsrammen.This is achieved by the alarm pane of the invention in that the electrically conductive loop-shaped web is placed in a corner portion of the prestressed silicate glass at such a distance from the edges of the glass layer that at least portions of the web sit within the light opening, ie. outside the edge area, which is later covered by the built-in frame.
15 Ved den angivne placering af den elektrisk leden de sløjfeformede bane opnås en i forhold til den kendte ovenfor beskrevne teknik væsentlig forøget sikkerhed for, at den ledende bane brydes ved brud af det forspændte silikatglaslag. Ved at i det mindste en del af 20 den ledende bane er beliggende inden for lysåbningen opnås, at brudstykker af glaslaget, med fastbrændt elektrisk ledende materiale, efter knusning af glasset ikke fastholdes mod hinanden af indramningen, hvilket ellers kunne medføre, at der blev opretholdt en elektrisk le-25 dende forbindelse mellem sløjfebanens kontaktsteder.At the indicated location of the electrically articulated loop-shaped web, a substantially increased assurance is obtained in relation to the prior art described above that the conductive web is broken by breaking the prestressed silicate glass layer. By having at least a portion of the conductive web within the light aperture, it is achieved that fragments of the glass layer, with a burnt electrical conductive material, after crushing the glass are not held against each other by the framing, which could otherwise cause it to be maintained an electrically conductive connection between the contact points of the loop path.
Ved at placere den ledende sløjfe i et hjørneparti af glaslaget i nærheden af glaslagets to kanter, som i det mindste i dette område er forbundet med de andre glaslag i alarmruden, udnyttes den overraskende effekt, 30 at da den side af glaslaget, der er modsat siden med den ledende bane, under belastning ikke kan udvide sig frit i området ved banen, da den fastholdes af samlingen til de øvrige lag, hvorimod den side af glaslaget, hvor banen er anbragt, kan udvide sig uden den samme begræns-35 ning, vil revner, der opstår i glaslaget, have tilbøje- 3 149241 lighed til at åbne sig mere ved ydersiden end ved den mod de øvrige lag vendende side, og derved medvirke til, at der med sikkerhed sker en afbrydelse af den ledende bane, så snart der forekommer revner i området af glas-5 set ved banen.By placing the conductive loop in a corner portion of the glass layer near the two edges of the glass layer, which is at least in this region connected to the other glass layers in the alarm pane, the surprising effect is utilized that, since the side of the glass layer opposite the side of the conductive web, under load, cannot expand freely in the region of the web, as it is held by the assembly to the other layers, whereas the side of the glass layer where the web is placed can expand without the same restriction, cracks occurring in the glass layer will have the tendency to open more on the outside than on the side facing the other layers, thereby contributing to the interruption of the conductive path as soon as possible cracks occur in the area of glass-5 seen at the track.
I en foretrukket udførelsesform af opfindelsen har den elektrisk ledende, sløjfeformede bane en sprød korrosionsbeskyttelsesbelægning bestående af en fastbrændt keramisk farve. Det opnås herved, at alarmrudens 10 funktionsevne ikke påvirkes gennem længere tids udsættelse for korroderende indvirkninger, og at korrosionsbeskyttelseslaget revner uden at forlænge sig, på samme måde som glaslaget og den ledende sløjfebane. Ved at lade korrosionsbeskyttelseslaget bestå af en uigennem-15 sigtig brændbar farve, opnås at den ledende sløjfe, som udgør en væsentlig del af alarmsystemet, holdes skjult.In a preferred embodiment of the invention, the electrically conductive, loop-shaped web has a brittle corrosion protection coating consisting of a burnt ceramic paint. It is hereby achieved that the functioning of the alarm pane 10 is not affected by prolonged exposure to corrosive effects and that the corrosion protection layer cracks without elongation, in the same way as the glass layer and the conductive loop path. By allowing the corrosion protection layer to consist of an opaque combustible color, it is achieved that the conductive loop, which forms an essential part of the alarm system, is kept hidden.
Opfindelsen vil nu blive forklaret ved hjælp af nogle udførelseseksempler og med henvisning til tegningen, på hvilken 20 fig. 1 er et billede af en alarmrude ifølge op findelsen og med flere lag isolerende glas, fig. 2 et snitbillede efter linien II-II i fig. 1, fig. 3 et snitbillede efter linien III-III i 25 fig. 1, og fig. 4 et billede af en alarmrude ifølge opfindelsen med kompounderede glaslag.The invention will now be explained by means of some exemplary embodiments and with reference to the drawing, in which FIG. 1 is a view of an alarm pane according to the invention and with several layers of insulating glass; FIG. 2 is a sectional view taken along line II-II of FIG. 1, FIG. 3 is a sectional view taken along line III-III in FIG. 1, and FIG. 4 is a view of an alarm pane according to the invention with compound glass layers.
Den i fig. 1 viste alarmrude med flere lag glas har et på termisk måde forspændt silikatglas-30 lag 1 og en af to glaslag 2 og 3, som er forbundet med hinanden ved hjælp af et plastisk mellemlag 4, bestående kompoundglasrude. Kompoundglasruden 5 er forbundet med det forspændte glaslag 1 ved mellemkobling af en afstandsramme 6 i form af et hul-35 profil. Sammenklæbning og beskyttelse er udført på 4 149241 kendt måde med lim- og forseglingslagene 7 og 8, som for det første ligger mellem afstandsrammen 6 og giaslagene, og for det andet er anbragt i en hulkel 8, som dannes af afstandsrammen og kantområderne på de 5 tilstødende glaslag. Så langt ligner opbygningen af alarmruden ifølge opfindelsen de kendte indbrudsfore-byggende isoleringsglasruders opbygning.The FIG. 1, a multi-layer glass alarm panel shown has a thermally biased silicate glass layer 1 and one of two glass layers 2 and 3, which are connected to each other by means of a compound glass layer 4, consisting of compound glass window. The compound glass pane 5 is connected to the prestressed glass layer 1 by interconnecting a spacer frame 6 in the form of a hollow profile. Adhesion and protection are performed in known manner with the adhesive and sealing layers 7 and 8, which are firstly located between the spacer frame 6 and the sliding layers, and secondly are arranged in a hollow 8 formed by the spacer frame and the edge regions of the 5 adjacent glass layers. So far, the structure of the alarm pane according to the invention resembles the structure of the known burglar-proof insulating glass panes.
Alarmruden er efter indbygningen i vinduesåbningen omgivet af en ramme, der omtrent når til den med 10 L markerede linie, således at vinduets lysåbning begynder på den anden side af linien L. I dette af rammen ikke tildækkede område af lysåbningen er der på den udvendige overflade af det forspændte glaslag 1 anbragt en ledende, sløjfeformet bane 10. Alarm-15 ruden indsættes således, at overfladen med den sløjfeformede bane 10 vender ind mod det rum, der skal beskyttes , medens kompoundglaslaget 5 vender udad.The alarm window, after being built into the window opening, is surrounded by a frame that approximately reaches the line marked with 10 L, so that the window's light opening begins on the other side of the line L. In this area of the light opening that is not covered, there is on the outside surface. of the prestressed glass layer 1 is arranged a conductive, loop-shaped web 10. The alarm-15 pane is inserted so that the surface with the loop-shaped web 10 faces the space to be protected while the compound glass layer 5 faces outwards.
Den ledende bane 10 består af en fastbrændt emaljelignende sølvleder, dvs. en blanding af 20 letsmeltelig glas og metalliske sølvpartikler, og som er kendt til dette formål. Blandingen, der findes som en pasta, der kan bruges til trykning, bliver påtrykt glaslaget l's overflade ved hjælp af silketryk. Den ledende bane 10 er fortrinsvis meanderformet. Banens 25 to ender har hver især en skiveformet udvidelse 11, hvorpå der er loddet tilslutningselementer 12, via hvilke den elektriske sammenkobling med den elektriske signalkreds finder sted.The conductive path 10 consists of a burnt enamel-like silver conductor, i. a mixture of 20 easily digestible glass and metallic silver particles, which is known for this purpose. The mixture, which can be used as a printable paste, is applied to the surface of the glass layer 1 by silk screen printing. The conductive path 10 is preferably meander shaped. The two ends of the web 25 each have a disc-shaped extension 11 on which are soldered connecting elements 12, through which the electrical interconnection with the electrical signal circuit takes place.
Over den ledende bane 10 ligger der et korro-30 sionsbeskyttelseslag 15. Det består ligesom den ledende bane 10 af et sprødt materiale, nemlig en keramisk farve. Dette korrosionsbeskyttelseslag 15 påtrykkes i pastaform ved hjælp af silketryk. Påtrykningen af laget 15 sker i en anden trykfase, når den 35 påtrykte ledende sløjfeformede bane 10 er tør. Når det påtrykte lag 15 er tørt, fastbrændes den sløjfe- 5 149241 formede bane 10 og beskyttelseslaget 15 i en og samme varmebehandlingsproces, nemlig under den nødvendige opvarmning til omkring 620°C til forspændingen.Above the conductive web 10 there is a corrosion protection layer 15. It, like the conductive web 10, consists of a brittle material, namely a ceramic color. This corrosion protection layer 15 is applied in paste form by silk screen printing. The printing of layer 15 occurs in a second printing phase when the 35 printed conductive loop-shaped web 10 is dry. When the applied layer 15 is dry, the loop-shaped web 10 and the protective layer 15 are burned in one and the same heat treatment process, namely during the required heating to about 620 ° C for the bias.
Over sløjfebanen 10's kontaktsteder 11 har 5 korrosionsbeskyttelseslaget 15 udsparinger 16 for at tillade adgang til fladerne 11, hvorpå tilslutningselementerne 12 siden fastloddes.Over the contact points 11 of the loop path 10, the corrosion protection layer 15 has recesses 16 to allow access to the surfaces 11, whereupon the connection elements 12 are subsequently soldered.
Korrosionsbeskyttelseslaget 15 er fortrinsvis opalt, dvs. ugennemsigtigt. Derved er det ikke muligt 10 udefra at se de nødvendige elementer til forbindelsen med sløjfebanen. Et velegnet materiale til dette formål er eksempelvis en keramisk fastbrændbar farve fra firmaet DEGUSSA, og som leveres under betegnelsen "Farben fur Bauglas" i pastaform og velegnet til silke-15 tryk.The corrosion protection layer 15 is preferably opal, i.e. opaque. Thus, it is not possible to see from the outside the necessary elements for the connection with the loop path. A suitable material for this purpose is, for example, a ceramic combustible paint from the company DEGUSSA, which is supplied under the designation "Farben fur Bauglas" in paste form and suitable for silk-screen printing.
Når det forspændte glaslag 1 knuses med vold fra alarmrudens udvendige side, buler glaslaget 1 ud til siden mod rummet som følge af forbindelsen med afstandsrammen 6 og begunstiget af stødet eller sla-20 get på den mod afstandsrammen 6 liggende side, således at den totale afbrydelse i den ledende bane 10 garanteres.When the prestressed glass layer 1 is violently crushed from the outside of the alarm pane, the glass layer 1 bulges to the side towards the space due to the connection to the spacer frame 6 and favored by the impact or impact on the side lying against the spacer frame 6, so that the total interruption in the conductive path 10 is guaranteed.
Den i fig. 4 viste alarmrude adskiller sig kun fra den tidligere beskrevne udførelsesform ved opbyg-25 ningen af lagene. Den ledende bane 10 bæres af et forspændt glaslag 21, som i dette tilfælde på hele fladen er forbundet med et ikke forspændt glaslag 22 via et plastisk mellemlag 23. For at forhøje sikkerheden mod indbrud er endnu et giaslag 24 sat sammen 30 med glaslaget 22 ved hjælp af et termoplastisk mellemlag 25. Denne alarmrude, der er fremstillet som en trelags kompoundglasrude, indsættes således i vinduesåbningen, at den ledende bane 10 vender indad mod det rum, der skal beskyttes. Ved en knusning 35 af det forspændte glaslag 21 er den dermed forbundne overflade på glaslaget 22 stærkere forhindretThe FIG. 4 only differs from the previously described embodiment in the construction of the layers. The conductive web 10 is supported by a prestressed glass layer 21, which in this case is connected to the entire surface of a non-prestressed glass layer 22 via a plastic intermediate layer 23. In order to increase the security against break-in, another sliding layer 24 is joined 30 with the glass layer 22 at by means of a thermoplastic intermediate layer 25. This alarm pane, manufactured as a three-layer compound glass pane, is inserted into the window opening so that the conductive path 10 faces inward against the space to be protected. By crushing 35 of the biased glass layer 21, the associated surface of the glass layer 22 is more strongly prevented.
