Description
Sicherungsanordnung für scheibenförmige, elektrischFuse arrangement for disk-shaped, electrical
nichtleitende Objekte, insbesondere Init Flachglas: Elektronische Sicherungseinrichtungen für scheibenförmige, elektrisch nichtleitende Objekte, insbesondere mit Flachglas, auf kapazitiver Grundlage, bei denen durch nderungen im Dielektrikum bzw. im elektrischen Feld ein Signal ausgelöst wird, sind im allgemeinen bekannt und insoweit Stand der Technik. Es bestehen jedoch technische Schwierigkeiten, größere Objekte, wie z.B. Fensterscheiben, auf diese Weise zu sichern, da die Kapazitätsänderung bei Annäherung, Berührung oder Bruch sehr gering ist. Man verwendet daher zur Sicherung derartiger Objekte in der Regel andere physikalische Prinzipien (Induktionsschleifen, Lichtschranken etc.).non-conductive objects, especially init flat glass: electronic Safety devices for disk-shaped, electrically non-conductive objects, in particular with flat glass, on a capacitive basis, where there are changes in the dielectric or a signal is triggered in the electric field, are generally known and to that extent state of the art. However, there are technical difficulties, major ones Secure objects such as window panes in this way, since the change in capacitance is very small when approached, touched or broken. It is therefore used for backup such objects usually have different physical principles (induction loops, Light barriers etc.).
Durch die Anordnung nach der Erfindung wird eine ausreichende Veränderung des Dielektrikums bzw. des elektrischen Feldes in den obengenannten Fällen erreicht, um ein Ansprechen der Sicherungseinrichtung herbeizuführen.The arrangement according to the invention provides a sufficient change of the dielectric or the electric field achieved in the above cases, to cause the safety device to respond.
Die kapazitive Sicherungsanordnung für nichtleitende Objekte nach der Erfindung ist dadurch gekennzeichnet, daß diese Objekte eine leitende Umrandung aufweisen, die als Belag einer Kapazität so geschaltet ist, daß bei Annäherung, Berührung oder Bruch ein Signal ausgelöst wird.The capacitive fuse arrangement for non-conductive objects according to the invention is characterized in that these objects have a conductive border have, which is connected as a covering of a capacitance so that when approaching, Touching or breaking a signal is triggered.
So kann zum Beispiel eine Glasscheibe in einer elektrisch leitenden Fassung-gehalten sein, die ihrerseits in einem nichtleitenden Rahmen befestigt ist, wie es in der Figur 1 dargestellt ist. Hierbei ist 1 die Scheibe, 2 die leitende Fassung und 3 der nichtleitende Rahmen.For example, a pane of glass can be converted into an electrically conductive one Be held, which in turn is fixed in a non-conductive frame, as shown in FIG. Here 1 is the disc, 2 is the conductive one Version and 3 the non-conductive frame.
Anstelle der die Scheibe haltenden Fassung kann auch die Kante der Scheibe metallisiert oder mit anderen, leitenden Materialien Sicherungsanordnung Blatt 2 versehen sein, wie Figur 2 zeigt. Hier ist nur die Belegung 4 der Scheibe 1, die wieder um im nichtleitenden Rahmen 3 befestigt ist, vorgesehen.Instead of the holder holding the disc, the edge of the Metallized disc or with other conductive materials Fuse arrangement Sheet 2 be provided, as Figure 2 shows. Here is only occupancy 4 of the disc 1, which is again attached to the non-conductive frame 3, is provided.
Eine weitere Möglichkelt besteht darin, einseitig am Rande der Scheibe ein leitendes Material als Umrandung anzubringen, wie es die Figur 3 zeigt. Hier ist 1 die Scheibe, 3 der nichtleitende Rahmen und 5 die streifenförinige Umrandung.Another possibility is one-sided on the edge of the disc to attach a conductive material as a border, as shown in FIG. here 1 is the pane, 3 the non-conductive frame and 5 the strip-shaped border.
Ebenso läßt sich auf beiden Seiten der Scheibe leitendes Material anbringen. Die Umrandung auf beiden Seiten bildet dann die Kondensatorbeläge, die dazwischen liegende Scheibe das Dielektrikum. Figur 4 zeigt die beiden Beläge 6a und 6b, wobei wieder 1 die Scheibe und 3 der nichtleitende Rahmen sind.Conductive material can also be used on both sides of the pane attach. The border on both sides then forms the capacitor plates, which disc between the dielectric. Figure 4 shows the two linings 6a and 6b, again 1 being the disc and 3 being the non-conductive frame.
Bei Doppelverglasungen wird zweckmäßig der Abstandhalter zwischen den beiden Scheiben metallisch und damit leitend ausgeführt. Eine solche Anordnung zeigt die Figur 5.In the case of double glazing, the spacer between the two disks are made of metal and therefore conductive. Such an arrangement shows the figure 5.
Zwischen den beiden Scheiben la und lb der Doppelverglasung liegt der leitende Metallrahmen 7 als Abstandhalter.Between the two panes la and lb of the double glazing is located the conductive metal frame 7 as a spacer.
Bei Ganzglas-Konstruktionen oder entsprechenden Hohlkörpern lassen sich leitende Beschläge oder Metallstreifen an den Kanten so anbringen, daß sie ebenfalls als Kondensatorbelag dienen können. Figur 6 zeigt am Beispiel einer Glasvitrine eine der vielen Möglichkeiten.Leave it for all-glass constructions or corresponding hollow bodies attach conductive fittings or metal strips to the edges so that they can also serve as a capacitor plate. Figure 6 shows the example of a glass showcase one of the many possibilities.
Durch die elektrisch leitende Umrandung der zu sichernden Fläche wird eine Empfindlichkeit erreicht, die eine auf kapazitive Grundlage arbeitende elektronische Sicherungseinrichtung bei Annäherung, Berührung oder Bruch sofort ansprechen lässt.The electrically conductive border of the area to be secured is Achieves a sensitivity that an electronic working on a capacitive basis Let the safety device respond immediately when it approaches, touches or breaks.
Richerungsanordnung Blatt 3 Zusätzlich lassen sich Vitrinen oder andere entsprechende Hohlkörper kapazitiv sichern, wenn sie einen elektrisch leitenden Boden- und/oder Deckenbelag enthalten. In diesem Fall entspricht die Sicherung nicht schon bei Annäherung oder Berührung, sondern erst beim unmittelbaren Hineingreifen in den Hohlkörper an. Figur 7 zeigt auch diese Anordnung. 1 sind hier die Wandungen, 8 sind die leitenden Beläge.Safety arrangement sheet 3 In addition, showcases or other Secure corresponding hollow bodies capacitively if they have an electrically conductive one Floor and / or ceiling covering included. In this case, the backup does not match already when approaching or touching, but only when reaching into it directly into the hollow body. Figure 7 also shows this arrangement. 1 here are the walls, 8 are the conductive coverings.
