FIG. 2 shows in cross section the arrangement of the switching strip 5 on the frame 11. The switching strips are mounted in a fixed manner on the frame, adjacent to the shearing counter closing edge 9s outside the area of the shearing counter closing edge 9s that overlaps with the shearing secondary closing edge 8s, for example 3 mm from the end of the coverage area removed. The safety edge in Fig. 2 has a profile housing which overlaps the switch, not shown here.

Figur 3 zeigt ein Prinzipschaltbild der elektrischen Schaltung von Antriebsmotor 4 und den Schaltern 6. Über die in Serie geschalteten Schalter 6 erhält der Antriebsmotor seine Betriebsspannung, z.B. 24 V Gleichstrom. Die Schalter sind mechanisch mit dem Gehäuse 10 der Schaltleiste verbunden. Wird nun während des Schließvorgangs des Kippflügels ein Gegenstand oder ein Körperteil (z.B. Finger) zwischen Blendrahmen 11 und Kippfensterflügel gebracht, so wird hierdurch auch ein Druck auf die Schaltleiste ausgeübt, die sich in unmittelbarer Nähe der Klemm-oder Quetschstelle befindet. Durch den Druck auf die Schaltleiste wird mindestens einer der Schalter 6 betätigt. Hierdurch wird die Stromzufuhr zum Antriebsmotor und damit auch der Schließvorgang des Kippflügels unterbrochen. Sobald der den Schließvorgang behindernde Körperteil oder Gegenstand aus dem Gefahrenbereich entfernt wird, federt die Schaltleiste wieder zurück und die Schalter 6 sind wieder alle in ihrer geschlossenen Grundstellung. Der Antriebsmotor 4 ist wieder mit seiner Betriebsspannung verbunden, und der Schließvorgang des Fensterflügels wird fortgesetzt. FIG. 3 shows a basic circuit diagram of the electrical circuit of the drive motor 4 and the switches 6. The drive motor receives its operating voltage, for example 24 V DC, via the switches 6 connected in series. The switches are mechanically connected to the housing 10 of the safety edge. If an object or a body part (eg fingers) is brought between the frame 11 and the tilting window sash during the closing process of the tilting sash, this also exerts pressure on the safety edge, which is located in the immediate vicinity of the clamping or crushing point. By pressing the safety edge, at least one of the switches 6 is actuated. As a result, the power supply to the drive motor and thus the closing process of the tilting wing is interrupted. As soon as the body part or object obstructing the closing process is removed from the danger zone, the safety edge springs back again and the switches 6 are all in their closed basic position again. The drive motor 4 is connected to its operating voltage again, and the closing process of the window sash is continued.

Figur 4 zeigt einen Querschnitt durch eine Schaltleiste. Das Gehäuse der Schaltleiste besteht aus einem U-förmigen Profil, vorzugsweise aus Aluminium. An der Innenwandung des rechten U-Schenkels ist ein weiteres U-Profil kleineren Querschnitts ausgebildet, das auf die Befestigungsleiste 16 aufgeklipst wird. Das Gehäuse 10 wird mit seiner U-förmigen Aussparung über die Befestigungsleiste 16 gedrückt, wobei die Gehäusenasen 10a in entsprechende Aussparungen in der Befestigungsleiste einrasten und einen sicheren Halt der Schaltleiste gewährleisten. Auf den Blendrahmen 11 ist mit Schrauben 15 die Befestigungsleiste 16 aufgeschraubt. Die Schrauben 15 sind vorzugsweise Blechschrauben mit Senkkopf. Die Befestigungsleiste weist entsprechende angesenkte Bohrungen für die Schrauben auf, so daß eine geringe Bauhöhe realisiert werden kann. Figure 4 shows a cross section through a safety edge. The housing of the safety edge consists of a U-shaped profile, preferably made of aluminum. On the inner wall of the right U-leg, a further U-profile of smaller cross-section is formed, which is clipped onto the fastening strip 16. The housing 10 is pressed with its U-shaped recess over the fastening strip 16, the housing lugs 10a snapping into corresponding recesses in the fastening strip and ensuring a secure hold of the switching strip. The fastening strip 16 is screwed onto the frame 11 with screws 15. The screws 15 are preferably self-tapping screws with countersunk head. The fastening strip has corresponding countersunk holes for the screws, so that a low overall height can be achieved.

Im Gehäuse 10 ist der Schalter 6, vorzugsweise ein wassergeschützter Mikroschalter, in eine entsprechende Profilaussparung an der Gehäuseinnenwand eingerastet. Das Gehäuse ist so profiliert, daß der Schalter direkt ins Gehäuse eingeklipst werden kann. Der Schalterknopf 14 ist an der unteren, dem Blendrahmen zugewandten Seite des Schalters 6 angeordnet. Durch die Profilform sowie die einseitige Befestigung des Gehäuses besitzt die Schaltleiste die Möglichkeit, sich bei Druck auf das Gehäuse um die Längsachse elastisch verdrehen zu können. Wird nun Druck auf das Gehäuse ausgeübt, z.B. durch einen Gegenstand zwischen Blendrahmen und Fensterflügel, so wird das Gehäuse niedergedrückt und dabei derart elastisch verformt, daß der Schalterknopf 14 gegen den Blendrahmen 11 gedrückt wird. Hierdurch wird der Schalter geöffnet und der Stromkreis zum Antriebsmotor unterbrochen. Der Schalterknopf ist hier an der unteren, dem Blendrahmen zugewandten Seite des Schalters 6 angeordnet.In the housing 10 there is the switch 6, preferably a water-protected microswitch, snapped into a corresponding profile recess on the inside wall of the housing. The housing is profiled so that the switch is clipped directly into the housing can be. The switch button 14 is on the lower, facing the frame Side of the switch 6 arranged. Due to the profile shape and the one-sided Fastening the housing, the safety edge has the option of joining Pressure on the housing to be able to turn elastically around the longitudinal axis. Becomes now put pressure on the housing, e.g. through an object between Frame and window sash, so the housing is depressed while doing so deformed so elastically that the switch button 14 against the frame 11th is pressed. This opens the switch and the circuit to the drive motor interrupted. The switch button is on the lower, the frame facing side of the switch 6 arranged.

In Figur 4 ist der Schalter 6 an der Innenwand im Bereich desjenigen Gehäuseschenkels angeordnet, der dem auf der Befestigungsleiste 16 aufgeklipsten Gehäuseschenkel gegenüberliegt.In Figure 4, the switch 6 is on the inner wall in the area of that housing leg arranged, the clipped on the mounting bracket 16 housing leg opposite.

Die mit dem Schalter 6 verbundenen elektrischen Anschlußleitungen 17 sind wasserdicht und elektrisch isolierend vergossen. Hierdurch wird ein geeigneter Berührschutz und Kurzschlußschutz der elektrischen Leitungen auch bei Betrieb mit Netzspannung (z.B. 230 V) sichergestellt. Ebenso ist der Schutz gegen Kondenswasser gewährleistet.The electrical connecting lines 17 connected to the switch 6 are watertight and cast electrically insulating. This creates a suitable protection against accidental contact and short-circuit protection of the electrical lines even when operated with Mains voltage (e.g. 230 V) ensured. Protection against condensation is also possible guaranteed.

Aufgrund der Profilgestaltung ist es möglich, die Schaltleiste mit nur einem Mikroschalter zu versehen., der vorzugsweise im mittleren Teil der Schaltleiste angeordnet ist. Das Profil ist so steif ausgeführt, daß der Schalter von jeder Stelle des Gehäuses aus betätigt werden kann. Due to the profile design, it is possible to switch the safety edge with just one microswitch to be provided., which is preferably arranged in the middle part of the safety edge is. The profile is so stiff that the switch from any point on the housing can be operated from.

Figur 5 zeigt einen Querschnitt durch eine andere Ausführung der Schaltleiste. Das Gehäuse 10 besteht aus einem formelastischen Material, vorzugsweise aus Kunststoff. Im Betriebszustand weist das Gehäuse einen geschlossenen, rechtekkigen Querschnitt auf. Der rechte untere Gehäuseteil ist als Biegelager 18 ausgeführt, um das die obere Gehäusehälfte in Längsrichtung gegenüber der unteren Gehäusehälfte gedreht werden kann. Die untere Gehäusehälfte ist mit ihrem Boden auf den Blendrahmen aufgeschraubt. Der Boden geht auf seiner rechten Seite in das Gehäuseoberteil über. Das Gehäuseoberteil weist einen U-förmigen Querschnitt auf und ist aus einem Stück mit dem Boden gefertigt, so daß das gesamte Gehäuse im wesentlichen rechteckigen Querschnitt erhält. Im linken unteren Bereich weist das Gehäuse eine Teilungsfuge 19 auf. Sie ist so gestaltet, daß das Gehäuseoberteil unter leichtem Druck in das Gehäuseunterteil eingreifen und einrasten kann. Die Teilungsfuge ist so ausgestaltet, daß sich das Gehäuseoberteil zum Gehäuseunterteil senkrecht zum Blendrahmen soweit verschieben kann, daß der Schalter 6 betätigt werden kann. Der Schalter 6, vorzugsweise ein Mikroschalter, ist in einer U-förmigen Ausnehmung des Gehäuseoberteils aufgenommen. Sein Schalterknopf 14 berührt in Betriebsstellung gerade das Gehäuseunterteil von innen oder befindet sich knapp darüber. Wird nun Druck auf die Schaltleiste ausgeübt, so wird die Gehäuseoberteil zusammen mit dem Schalter in Richtung Gehäuseunterteil verschoben, und der Schalterknopf wird eingedrückt. Hierdurch öffnet sich der Schalter. Figure 5 shows a cross section through another embodiment of the safety edge. The housing 10 consists of a resilient material, preferably of plastic. In the operating state, the housing has a closed, rectangular cross section. The lower right housing part is designed as a flexible bearing 18, around which the upper housing half can be rotated in the longitudinal direction with respect to the lower housing half. The bottom of the lower half of the housing is screwed onto the frame. The bottom merges with the upper part of the housing on its right side. The upper housing part has a U-shaped cross section and is made in one piece with the bottom, so that the entire housing has a substantially rectangular cross section. In the lower left area, the housing has a dividing joint 19. It is designed so that the upper housing part can engage and snap into the lower housing part under slight pressure. The parting line is designed so that the upper housing part to the lower housing part can move perpendicular to the frame so far that the switch 6 can be operated. The switch 6, preferably a microswitch, is received in a U-shaped recess in the upper housing part. Its switch button 14 just touches the lower part of the housing from the inside or is just above it in the operating position. If pressure is now exerted on the safety edge, the upper part of the housing is moved together with the switch in the direction of the lower part of the housing, and the switch button is pressed in. This will open the switch.

Die Befestigung der in Fig. 5 dargestellten Schaltleiste erfolgt über Schrauben 15, die an mehreren, gegenüber den Schaltern 6 räumlich versetzten Positionen direkt durch Bohrungen im Gehäuseunterteil in den Blendrahmen 11 eingeschraubt werden. Eine separate Befestigungsleiste ist nicht erforderlich.The safety edge shown in FIG. 5 is fastened by means of screws 15, the directly at several positions spatially offset from the switches 6 can be screwed into the frame 11 through holes in the lower housing part. A separate fastening strip is not necessary.

Aufgrund der Formelastizität der in Fig. 5 dargestellten Schaltleiste sind in der Schaltleiste mehrere (mindestens zwei) in Serie geschaltete Schalter 6 angeordnet, um an jeder Stelle ein zuverlässiges Schalten beim Berühren der Schaltleiste zu ermöglichen. Due to the formula elasticity of the switching strip shown in Fig. 5 are in the Safety edge several (at least two) switches 6 arranged in series, to ensure reliable switching at every point when touching the safety edge to enable.

Figur 6 zeigt im Querschnitt eine andere Ausführung der Schaltleiste mit einem Gehäuse 10 aus relativ formsteifem Material, vorzugsweise ein U-Profil aus Aluminium. Das Gehäuse übergreift eine in ihrer Querschnittsform zum Gehäuse komplementäre Befestigungsleiste 16, die eine geringfügig kleinere Höhe hat als das Gehäuse. Die Gehäusenasen 10a umgreifen eine entsprechende Fase auf jeder Seite der Befestigungsleiste 16. Die Befestigungsleiste ist vorzugsweise aus Kunststoff gefertigt. Sie bildet gleichzeitig eine Führung für das Gehäuse, die eine Bewegung des Gehäuses senkrecht zum Blendrahmen ermöglicht. In einer Aussparung der Befestigungsleiste ist der Mikroschalter 6 und der isolierte Kabelanschluß 17 angeordnet. Der zum Schalter 6 gehörende Schalterknopf 14 weist vom Blendrahmen weg und zur Innenseite des U-Profils hin. Der Schalterknopf berührt in Ruhestellung gerade das Gehäuse 10 von innen oder befindet sich dicht unterhalb des Gehäuses. Wird nun Druck auf das Gehäuse ausgeübt, so verschiebt sich das Gehäuse in Richtung Blendrahmen 11. Hierdurch wird der Schalterknopf 14 eingedrückt, und der Schalter wird geöffnet. Die Rückbewegung des Gehäuses erfolgt durch eine oder mehrere Federn 21 (s. Figur 7), die sich mit einem Ende von innen gegen das Gehäuse und mit ihrem anderen Ende gegen die Befestigungsleiste. Figure 6 shows in cross section another embodiment of the safety edge with a housing 10 made of relatively dimensionally stable material, preferably a U-profile made of aluminum. The housing overlaps a fastening strip 16 which is complementary in cross-sectional shape to the housing and has a slightly smaller height than the housing. The housing lugs 10a encompass a corresponding chamfer on each side of the fastening strip 16. The fastening strip is preferably made of plastic. At the same time, it forms a guide for the housing, which enables the housing to move perpendicularly to the frame. The microswitch 6 and the insulated cable connection 17 are arranged in a recess in the fastening strip. The switch button 14 belonging to the switch 6 points away from the frame and towards the inside of the U-profile. In the rest position, the switch button just touches the housing 10 from the inside or is located just below the housing. If pressure is now exerted on the housing, the housing moves in the direction of the frame 11. This causes the switch button 14 to be pressed in and the switch is opened. The housing is moved back by one or more springs 21 (see FIG. 7), one end of which is against the housing from the inside and the other end against the fastening strip.

Figur 7 zeigt einen Schnitt durch die in Fig. 6 dargestellt Ausführung der Schaltleiste, jedoch in einem anderen Bereich geschnitten. Durch das Druckfederelement 21, das in einer entsprechenden Aussparung der Befestigungsleiste 16 angeordnet ist, wird das Gehäuse von der Befestigungsleiste soweit weggedrückt, bis die Gehäusenase 10a an der Fasenkante der Befestigungsleiste anliegt. Durch das Federelement 21 wird eine Rückstellkraft erzeugt, die das Gehäuse wieder in seine Ausgangsposition zurückbewegt, nachdem es in Richtung des Blendrahmens 11 gedrückt wurde. FIG. 7 shows a section through the embodiment of the safety edge shown in FIG. 6, but cut in another area. The compression spring element 21, which is arranged in a corresponding recess in the fastening strip 16, pushes the housing away from the fastening strip until the housing nose 10a rests on the bevel edge of the fastening strip. A restoring force is generated by the spring element 21, which moves the housing back into its starting position after it has been pressed in the direction of the frame 11.

Die Befestigungsleiste 16 ist durch Schrauben 15 mit dem Blendrahmen 11 verschraubt. Das Gehäuse 10 wird zur Montage über die Befestigungsleiste geschoben, bis die Gehäusenasen 10a in die Fasen der Befestigungsleiste 16 einrasten.The fastening strip 16 is screwed to the frame 11 by screws 15. The housing 10 is pushed over the mounting strip for assembly, until the housing lugs 10a snap into the chamfers of the fastening strip 16.

Die in Figuren 1 bis 7 dargestellten Schaltleisten sind so ausgeführt, daß sie in einfacher Weise, z.B. mit einer Säge, abgelängt werden können. Die Schaltleistenlänge kann so auf die jeweiligen Einbauverhältnisse unterschiedlicher Fenstervarianten gekürzt werden. Hierdurch kann die Herstellung vereinfacht werden, da nur eine geringe Anzahl von Längenvarianten der Schaltleiste gefertigt werden muß, um den universellen Einbau an allen gängigen Fenstermodellen zu ermöglichen.The safety edges shown in Figures 1 to 7 are designed so that they in simple way, e.g. with a saw. The safety edge length can thus depend on the installation conditions of different window variants be shortened. This can simplify production, since only a small number of length variants of the safety edge must be manufactured, to enable universal installation on all common window models.

In einer anderen Variante enthält die Schaltleiste einen Druckschlauch. Wird Druck auf die Schaltleiste ausgeübt, so verändert sich der elektrische Widerstand des Schlauches. Hierdurch kann über eine geeignete Steuerung der Antriebsmotor abgeschaltet werden. In einer anderen Ausführung wird über die Druckänderung im Druckschlauch ein pneumatischer Schalter betätigt, der ebenfalls den Antriebsmotor abschaltet.In another variant, the safety edge contains a pressure hose. Will pressure exerted on the safety edge, the electrical resistance of the Hose. As a result, the drive motor can be switched off via a suitable control become. In another embodiment, the pressure change in the Pressure hose operated a pneumatic switch, which also drives the drive motor switches off.

In einer anderen Ausführung wird mittels einer geeigneten Steuerung bei Druck auf die Schaltleiste der Antriebsmotor abgeschaltet und dann mit umgekehrter Drehrichtung für eine bestimmte Zeitdauer wieder eingeschaltet. Hierdurch wird eine zusätzliche Sicherheit erreicht, da mehr Zeit zur Verfügung steht, um einen eingeklemmten Körperteil oder Gegenstand aus dem Gefahrenbereich zu entfernen.In another embodiment, pressure is applied by means of a suitable control the safety edge of the drive motor is switched off and then in the opposite direction switched on again for a certain period of time. This will create a Additional security is achieved as more time is available to get a jammed Remove body part or object from the danger area.

In einer anderen Ausführung ist der Blendrahmen mit einer Nut versehen, in der die Schaltleiste eingelassen werden kann, so daß sie nur noch soweit über die Blendrahmenoberfläche hinausragt, wie dies für eine sichere Betätigung im Gefahrenfall erforderlich ist. Durch diese Ausführung wird das optische Erscheinungsbild der Fensteranlage verbessert.In another embodiment, the frame is provided with a groove in which the safety edge can be inserted so that it is only as far over the The frame surface protrudes like this for safe operation in the event of danger is required. This design creates the visual appearance the window system improved.
