Description

Die Erfindung bezieht sich auf ein Schließkantensicherheitsprofil für kraftbetätigte Anlagen, wie Rolltore, Rollgitter, Türen, Schiebenanlagen und so weiter und Hebe-, Arbeitsbühnen und dergleichen, mit einem Hohlprofil aus elastomerem Material gemäß den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a closing edge safety profile for power-operated systems, such as rolling shutters, rolling grilles, doors, sliding systems and so on and lifting, working platforms and the like, with a hollow profile of elastomeric material according to the features of the preamble of claim 1.

Ein derartiges Profil ist aus der DE- 27 19 438 C2 bekannt. Dieses Profil hat im Anschluss an das Befestigungsprofil eine Leerkammer, die dem Nachlauf des Antriebes der kraftbetätigten Anlage dient, und im Anschluss daran eine Schaltkammer, in der Schaltelemente angeordnet sind, die stabförmig ausgebildet sind und in diese Kammer eingesetzt werden. Darüber hinaus weist dieses Profil am Ende noch ein Kammerprofil auf, das zur Verbesserung der Dichtheit dient.
Nachteilig bei diesem Profil ist, abgesehen davon, dass die Schaltelemente in die Schaltkammer eingeschoben werden müssen, dass die Schaltkammer mit Abstand zu dem Befestigungsprofil angeordnet ist. Insbesondere dann, wenn das Schließkantensicherheitsprofil in Bereichen mit Schmutz und Feuchtigkeit eingesetzt wird, ist diese Kammer schneller der Feuchtigkeit ausgesetzt. Darüber hinaus ist diese Kammer von ihrer Formgebung und Ausgestaltung her so ausgelegt, dass große Schaltkräfte erforderlich sind. Des Weiteren ist keine klare Trennung bezüglich des Kräfteverlaufs zwischen Nachlauf- und Schaltkammer zu erkennen.Such a profile is from the DE-27 19 438 C2 known. Following the fastening profile, this profile has an empty chamber which serves to follow the drive of the power-operated installation, and subsequently a switching chamber in which switching elements are arranged which are rod-shaped and are inserted into this chamber. In addition, this profile still has a chamber profile at the end, which serves to improve the tightness.
A disadvantage of this profile, apart from the fact that the switching elements must be inserted into the switching chamber, that the switching chamber is arranged at a distance from the mounting profile. In particular, when the closing edge safety profile is used in areas of dirt and moisture, this chamber is more exposed to moisture. In addition, this chamber is designed by its shape and design ago that large switching forces are required. Furthermore, no clear separation with respect to the flow of forces between the wake and switching chamber can be seen.

Es ist weiterhin ein Zweikammerprofil bekannt ( DE- 298 04 732 U1 ), wobei die äußere Kammer zur Druckwellenkontaktdetektion ausgebildet ist, an die sich eine der kraftbetätigten Anlage benachbarte elektrisch betätigte Schaltkammer anschließt. In diese elektrisch betätigte Schaltkammer kann eine Kontaktleiste eingeschoben werden, die aufgrund des vorgeschlagenen Herstellungsverfahrens (Einschieben der Kontaktleiste) als Kontaktbänder ausgebildet sein müssen, die eine hinreichende Steifigkeit aufweisen.
Die äußere Kammer weist einen zylindrischen Querschnitt auf und ist beidseits geschlossen, so dass eine Druckbelastung einen Druckanstieg der Luft in der zylindrischen Kammer verursacht, wodurch ein Schaltimpuls ausgelöst wird.
Es ist offensichtlich, dass es sich bei dem vorliegenden Auflaufprofil um zwei nebeneinander angeordnete Schaltkammern handelt, die beide Schaltimpulse auslösen und einer erhöhten Sicherheit dienen sollen.It is still known a two-chamber profile ( DE-298 04 732 U1 ), wherein the outer chamber for pressure wave contact detection is formed, to which a power-operated system adjacent electrically actuated switching chamber connects. In this electrically actuated switching chamber, a contact strip can be inserted, which must be formed as a contact bands due to the proposed manufacturing method (insertion of the contact strip), which have a sufficient rigidity.
The outer chamber has a cylindrical cross-section and is closed on both sides, so that a pressure load causes a pressure increase of the air in the cylindrical chamber, whereby a switching pulse is triggered.
It is obvious that the present casserole profile is two adjacently arranged switching chambers, which trigger both switching impulses and serve for increased safety.

Es ist noch ein Hohlkammerprofil bekannt ( DE- 44 27 537 A1 ), das zum Anschluss an Türen, zur Führung von Fenstern und zum Abdichten von Schiebedächern an Kraftfahrzeugen vorgesehen ist. Dieses Hohlprofil weist eine innere Schaltkammer auf, die mit einem besonderen "force sensing resistor"- Element ausgerüstet ist. Dieses Element weist keine beabstandeten Schaltelemente auf, die beim Zusammendrücken kontaktieren und damit einen Schaltimpuls auslösen, sondern basiert auf einem streifenförmigen Sensor, der bei Druck- oder Biegebelastung einen Schaltimpuls auslöst.There is still a hollow chamber profile known ( DE 44 27 537 A1 ), which is provided for connection to doors, for guiding windows and for sealing sunroofs on motor vehicles. This hollow profile has an inner switching chamber, which is equipped with a special "force sensing resistor" - element. This element has no spaced switching elements which contact upon compression and thus trigger a switching pulse, but based on a strip-shaped sensor which triggers a switching pulse under pressure or bending load.

Die Schaltkammer ist demzufolge mit einem Auslöse-/Druckpunkt ausgerüstet, wobei dieser Druckpunkt erst nach Zusammendrücken des äußeren Profils einen Schaltimpuls auslösen kann.The switching chamber is therefore equipped with a trigger / pressure point, this pressure point can only trigger a switching pulse after compression of the outer profile.

Aufgabe der vorliegenden Erfindung ist es, die Nachteile der angesprochenen Dokumente zu beheben und ein Schließkantensicherheitsprofil zur Verfügung zu stellen, das heutigen schnellen Antrieben für kraftbetätigte Anlagen entspricht, eine schnelle . Auslösung der Schaltimpulses bei noch geringen Kräften sicherstellt und auch für Auslösekräfte aus verschiedenen Richtungen, auch seitlichen Richtungen, gut geeignet ist.The object of the present invention is to remedy the disadvantages of the mentioned documents and to provide a closing edge safety profile which corresponds to today's fast drives for power-operated systems, a fast one. Activation of the switching pulse ensures even lower forces and also for release forces from different directions, including lateral directions, is well suited.

Gelöst wird die Aufgabe der Erfindung durch, die Merkmale des Anspruchs 1, wobei das an die Schaltkammer anschließende äußere Kammerprofil als Nachlaufkammer ausgebildet ist.
Dadurch sind die Hebelarme der Auslösekräfte, insbesondere auch dann, wenn sie seitlich angreifen, gegenüber dem Befestigungsprofil, das am Ende der Tore und der gleichen angeordnet ist und die Festeinheit bildet, größer, so dass die Auslösung der Schaltimpulse schneller und eindeutiger erfolgt.
Dabei sind an der dem Befestigungsprofil abgewandten Innenfläche der Schaltkammer elektrisch leitende wulst- oder leistenartige Vorsprünge vorgesehen. In der Schaltkammer ist an der gegenüberliegenden Seite eine elektrisch leitende Gegenfläche angeordnet. Durch diese wulst-und/oder leistenartigen Vorsprünge, die natürlich der Größe der Schaltkammer angepasst sind und einer elektrisch leitenden Gegenfläche an der gegenüberliegenden Seite der Schaltkammer zugeordnet sind, entsteht bereits bei kleinen Bewegungen der Schaltkammer eine Berührung der Vorsprünge mit der Gegenfläche, so dass bereits frühzeitig ein Schaltimpuls ausgelöst wird.
Die elektrisch leitenden wulst- oder leistenartigen Vorsprünge sind zu einem Strang zusammengefasst. Der Strang ist Bestandteil eines Innenkörpers, der durch Beigaben von elektrisch leitenden Stoffen, wie Ruß, Graphit, Metallpulver und dergleichen elektrisch leitend ist. Durch diese Merkmale entsteht eine Baueinheit, die eine hohe Leitfähigkeit und eine gute Stabilität aufweist. Der an den Innenkörper anschließende Bereich des Hohlprofils ist nicht leitend ausgeführt.The object of the invention is achieved by the features of claim 1, wherein the adjoining the switching chamber outer chamber profile is formed as a follow-up chamber.
As a result, the lever arms of the release forces, especially when they attack laterally, compared to the attachment profile, which is arranged at the end of the gates and the same and forms the fixed unit, larger, so that the triggering of the switching pulses is faster and clearer.
In this case, on the side facing away from the fastening profile inner surface of the switching chamber electrically conductive bead or strip-like projections are provided. In the switching chamber an electrically conductive counter-surface is arranged on the opposite side. By this bead-and / or strip-like projections, which are of course adapted to the size of the switching chamber and an electrically conductive counter surface on the opposite side of the switching chamber are assigned, even with small movements of the switching chamber is a touch of the projections with the counter surface, so that already early a switching pulse is triggered.
The electrically conductive bead or strip-like projections are combined into one strand. The strand is part of a Inner body, which is electrically conductive by adding electrically conductive substances, such as carbon black, graphite, metal powder and the like. These features create a structural unit that has high conductivity and good stability. The adjoining the inner body region of the hollow profile is not designed to be conductive.

Auch die Gegenfläche weist leistenartige Erhebungen auf, die zu dem Strang mit Vorsprüngen seitlich versetzt angeordnet sind. Dabei sind insbesondere zwei leistenartige Erhebungen, die etwa der Höhe der Vorsprünge und/oder dem Strang mit den Vorsprüngen entsprechen, besonders vorteilhaft. Da der Innenkörper eine gewisse Breite aufweist und neben dem Strang zu den wulst- oder leistenartigen Vorsprüngen passende Kontaktflächen bildet, können die wulst- oder leistenartigen Vorsprünge diese Flächen berühren und einen Impuls auslösen. Sie können aber auch bei seitlicher Verschiebung die wulst- oder leistenartigen Vorsprünge beziehungsweise den Strang berühren und dabei Schaltimpulse erzeugen. Es können auch Mehrfachkontaktierungen je nach Krafteinwirkung und Intensität dadurch entstehen, dass die Vorsprünge mit der Gegenfläche in Berührung treten und die Erhebungen mit den Flächen neben dem Strang an dem Innenkörper.Also, the counter surface has strip-like elevations, which are arranged offset laterally to the strand with projections. In particular, two strip-like elevations, which correspond approximately to the height of the projections and / or the strand with the projections, are particularly advantageous. Since the inner body has a certain width and adjacent to the strand to the bead or strip-like projections forms mating contact surfaces, the bead or strip-like projections can touch these surfaces and trigger a pulse. But you can also touch the bead or strip-like protrusions or the strand in lateral displacement and thereby generate switching pulses. It can also Mehrfachkontaktierungen depending on the force and intensity arise from the fact that the projections come into contact with the mating surface and the elevations with the surfaces next to the strand on the inner body.

In vorteilhafter Weise ist die Gegenfläche Bestandteil eines Mantelkörpers, der durch Beigaben von leitenden Stoffen, wie Ruß, Graphit, Metallpulver und dergleichen elektrisch leitend ist. Der daran anschließende Bereich des Hohlprofils ist nicht leitend ausgeführt.
Zur weiteren Verbesserung der Leitfähigkeit wird vorgeschlagen, dass im Innenkörper und/oder im Mantelkörper ein elektrischer leitender Draht eingebettet ist, der/die auch zum besseren Anschluss der Leitung zu der Auswerteeinheit benutzt werden können.Advantageously, the mating surface is part of a sheath body, which is electrically conductive by the addition of conductive substances, such as carbon black, graphite, metal powder and the like. The adjoining region of the hollow profile is not designed to be conductive.
To further improve the conductivity is proposed that in the inner body and / or in the sheath body, an electrically conductive wire is embedded, which can also be used for better connection of the line to the evaluation.

Um eine möglichst rasche und definierte Kontaktierung in der Schaltkammer zu erreichen, wird weiterhin vorgeschlagen, dass der Übergangsquerschnitt zwischen den Kammerprofilen Einschnürungen, vorzugsweise beidseitig von außen eingearbeitete Längskerben aufweist. Weiterhin können die Wände der Schaltkammer seitlich neben den Schaltelementen beziehungsweise den wulst- und/oder leistenartigen Vorsprüngen und der Gegenfläche einen geringeren Querschnitt aufweisen, als die in Verlängerung derselben vorgesehenen Wände der Nachlaufkammer.
Schließlich kann die Schaltfunktion weiterhin noch dadurch verbessert werden, dass die Wände der Schaltkammer zwischen den Längskerben und dem Befestigungsprofil bogenförmig gekrümmt sind. Dadurch entstehen weiche Wände, die nicht erst geknickt werden müssen, bevor sie nachgeben und eine Berührung der Schaltelemente erlauben.In order to achieve the fastest possible and defined contacting in the switching chamber, it is further proposed that the transition cross section between the chamber profiles constrictions, preferably on both sides from the outside incorporated longitudinal notches. Furthermore, the walls of the switching chamber laterally next to the switching elements or the bead and / or strip-like projections and the counter surface may have a smaller cross-section than the extension provided in the same walls of the trailing chamber.
Finally, the switching function can be further improved by the fact that the walls of the switching chamber between the longitudinal notches and the mounting profile are arcuately curved. This results in soft walls that do not have to be kinked before they give way and allow contact of the switching elements.

In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, dass an der Nachlaufkammer in Verlängerung einer der Kammerwände eine Dichtlippe angeordnet ist. Diese Dichtlippe hat unabhängig von ihrer Dichtfunktion weiterhin den Vorteil, dass sie in Verbindung mit der Gesamtkonzeption des Schließkantensicherheitsprofils, insbesondere der Ausgestaltung der Schaltelemente und der Schaltkammer, eine schnellere Auslösung von Schaltimpulsen dann bewirkt, wenn die Kräfte senkrecht oder aus der Richtung auf das Schließkantensicherheitsprofil einwirken, in die die Dichtlippe zeigt.In a further embodiment of the invention, it is proposed that a sealing lip is arranged on the overflow chamber in extension of one of the chamber walls. Regardless of its sealing function, this sealing lip also has the advantage that, in conjunction with the overall concept of the closing edge safety profile, in particular the configuration of the switching elements and the switching chamber, a faster triggering of switching pulses is effected when the forces act perpendicularly or out of the direction on the closing edge safety profile into which the sealing lip points.

Das Schließkantensicherheitsprofil mit Befestigungsprofil, Kammerprofilen, wulst- und/oder leistenartigen Vorsprüngen, Erhebungen, einschließlich Drähten, kann einstückig hergestellt, insbesondere extrudiert oder eingedüst werden.The closing edge security profile with fastening profile, chamber profiles, bead and / or strip-like projections, elevations, including wires, can be produced in one piece, in particular extruded or injected.

Zur weiteren Erläuterung der Erfindung wird auf die Zeichnung verwiesen, in der ein Ausführungsbeispiel der Erfindung vereinfacht dargestellt ist.For further explanation of the invention reference is made to the drawing, in which an embodiment of the invention is shown in simplified form.

Die Figur zeigt einen Querschnitt durch ein Schließkantensicherheitsprofil, das in beliebigen Längen hergestellt und am Ende von kraftbetätigten Anlagen befestigt werden kann.The figure shows a cross section through a closing edge safety profile that can be made in any length and attached to the end of power plants.

In der Figur ist allgemein mit 1 ein Schließkantensicherheitsprofil bezeichnet, das ein Befestigungsprofil 2, eine profilartige Schaltkammer 3 und eine als Profil ausgebildete Nachlaufkammer 4 aufweist.
An der dem Befestigungsprofil abgewandten Innenfläche der Schaltkammer 3 ist ein mit 5 bezeichneter Innenkörper eingearbeitet, der einstückig mit der Wand des Befestigungsprofils hergestellt ist. Der Innenkörper unterscheidet sich dadurch von der übrigen Wandung, dass er durch Beigabe von leitenden Stoffen elektrisch leitend ausgebildet ist. Mit eingebettet ist auch ein mit 6 bezeichneter Draht. Etwa mittig auf dem Innenkörper sind wulst- und/oder leistenartige Vorsprünge 7 angeformt, die im Querschnitt gesehen kleeblattförmig ausgebildet sind und entlang des Innenkörpers strangartig verlaufen. In der gegenüberliegenden Wand der Schaltkammer ist ein Mantelkörper 8 eingebettet, der einstückig mit der Wand hergestellt und durch Beigabe von leitenden Stoffen elektrisch leitend ausgebildet ist. An dem Mantelkörper 8 sind wulst- und/oder leistenartige Erhebungen 9 angebracht, die seitlich neben den Vorsprüngen 7 verlaufen und etwa die gleiche Höhe wie der Strang mit Vorsprüngen aufweisen. In der Nähe einer Erhebung ist in dem Mantelkörper 8 ebenfalls ein elektrisch leitender Draht 6 eingebaut. Die äußere Breite der Schaltkammer entspricht etwa der der Nachlaufkammer. Sie hat allerdings nur eine geringe Höhe (innere Erstreckung in Richtung Befestigungsprofil zu Nachlaufkammer), während die Nachlaufkammer (in derselben Richtung gesehen) zumindest doppelt so hoch ist. Weiterhin sind die seitlichen Wände der Schaltkammer bogenförmig gekrümmt und wesentlich dünner ausgeführt als die anschließenden seitlichen Wände der Nachlaufkammer, die auch im Wesentlichen gerade ausgeführt sind. Durch diese Ausgestaltung und Formgebung der Wände der Schaltkammer und der Nachlaufkammer ergeben sich besonders günstige Verhältnisse für eine schnelle Auslösung von Schaltimpulsen. Zwischen den Kammern sind auf den Außenseiten Längskerben 10 eingearbeitet, die die beschriebene Auslösekinematik noch verstärken.
Weiterhin ist in Verlängerung einer der Wände der Nachlaufkammer eine mit 11 bezeichnete Dichtlippe angeformt. Auch diese Dichtlippe trägt zum definierten Schalten in der Schaltkammer bei, weil bei einer Krafteinwirkung etwa senkrecht zur Mittellinie, die in Verlängerung der Schaltlippe angeordnete bogenförmige Wand der Schaltkammer eine höhere Krafteinwirkung erfährt und sich verformt, so dass bereits sehr frühzeitig eine Kontaktierung der Erhebung mit der Gegenfläche beziehungsweise mit einem der Vorsprünge erfolgt.In the figure, a closing edge safety profile is generally denoted by 1, which has a fastening profile 2, a profile-like switching chamber 3 and a trailing chamber 4 designed as a profile.
On the side facing away from the mounting profile inner surface of the switching chamber 3, a designated 5 inner body is incorporated, which is made in one piece with the wall of the mounting profile. The inner body differs from the rest of the wall in that it is formed by the addition of conductive materials electrically conductive. Embedded is also a designated 6 wire. Approximately centrally on the inner body bead and / or strip-like projections 7 are formed, which are seen in cross-cloverleaf shape and extend along the inner body strand-like. In the opposite wall of the switching chamber, a jacket body 8 is embedded, which is made in one piece with the wall and formed by the addition of conductive materials electrically conductive. On the jacket body 8 bead and / or strip-like elevations 9 are mounted, which extend laterally next to the projections 7 and have approximately the same height as the strand with projections. In the vicinity of a survey, an electrically conductive wire 6 is also installed in the sheath body 8. The outer width of the switching chamber corresponds approximately to the lag chamber. However, it has only a small amount (inner extent in the direction of attachment profile to the trailing chamber), while the trailing chamber (seen in the same direction) is at least twice as high. Furthermore, the lateral walls of the switching chamber are arcuately curved and made substantially thinner than the subsequent lateral walls of the trailing chamber, which are also performed substantially straight. This configuration and shaping of the walls of the switching chamber and the after-running chamber result in particularly favorable conditions for a quick release of switching pulses. Between the chambers longitudinal notches 10 are incorporated on the outer sides, which reinforce the triggering kinematics described.
Furthermore, in the extension of one of the walls of the trailing chamber, a sealing lip denoted by 11 is formed. These sealing lip also contributes to the defined switching in the switching chamber, because at a force approximately perpendicular to the center line, arranged in extension of the switching lip arcuate wall of the switching chamber experiences a higher force and deformed, so that already very early contacting the survey with the Counter surface or with one of the projections takes place.

Auch bei schräger Krafteinwirkung auf die Dichtlippe wird schräg und damit verstärkt auf die Schaltkammer eine Kraft ausgeübt, die zu sicheren Kontaktierung bei noch geringen Kräften führt.Even with an oblique force acting on the sealing lip is exerted obliquely and thus exerted on the switching chamber, a force that leads to secure contact with even low forces.
