Definitions
- the invention relates to an edge protection device according to the preamble of claim 1.
- Edge protection devices for mounting on moving objects, in particular on edges, for example, from closing sliding doors or lift doors od. Like., As tarnish or trapping are known. Such edge protection devices prevent injury or damage when starting the edge or the edge protection device on or against an obstacle.
- edge protection strip is provided, which is fastened to the edge via two parallel straight guide rods.
- the guide rods are pivotally mounted at both ends, whereby a compelling parallel guidance between the edge protection strip and the edge is ensured.
- a relative movement of the edge protection strip with respect to the edge which corresponds to the length of the guide rods, likewise necessarily ensues.
- the edge protection strip is offset parallel to the edge and either raised or lowered.
- Such devices are for example from the US Pat. No. 3,537,211 , of the CH 283 179 A or the US Pat. No. 3,159,728B known.
- the object of the invention is therefore to provide an alternative edge protection device, which ensures a movement of the edge protection strip in a height or level with the edge or the door and without heightwise relative displacement while avoiding the said disadvantage.
- the characterizing features of claim 1 have the advantage that when installing the edge protection strip no consideration must be taken to a possible height-related relative movement of the edge protection strip with respect to the edge.
- the edge protection bar moves towards the edge while maintaining the parallel orientation, an upward or downward shift does not occur. This facilitates installation and simplifies the construction. In addition, so danger spots are avoided, which can be caused by the height relative movement of the edge protection strip.
- the edge protection device according to the invention given a caster, within which the closing door or edge must come to a halt.
- the means for fixing the edge protection strip is created.
- the means thus formed are stable and durable and ensure the parallel guidance of the edge protection strip.
- This embodiment is structurally designed such that a permanent operation is possible and the structural stability is improved.

- the features of claim 10 are provided.
- the springs can be arranged in different places. It is advantageous here that there is a degression of the spring force during compression of the edge protection device.
- the compression of the edge protection strip initially exerts a large force on moving edges when hitting an obstacle, which force is detected by detection means and initiates and effects the stopping or reversing of movement of the moving edge.
- the edge protection ledge of the moving edge just this sufficient overtravel, so that even large masses within the given safety standards can be brought to a standstill without the trapped obstacle to exert too much force. Due to the interaction of the spring action in the described direction and the action of the external forces perpendicular thereto via the scissors, a strong degression of the force is achieved toward the end of the movement, which emits the depressed edge to the outside.
- the door or the gate must not be locked in the closed position, since the residual force of the edge protection device is not sufficient to press it.

- Fig. 5a and 5b show a further embodiment of the edge protection device with also soft and flexible connecting elements 10 'and 10 ", which also, as in Fig. 4a and 4b , are formed only as traction means.
- the operation is the same: as soon as the edge protection device is compressed, the outer pivot bearing of the second main scissor 4b moves outward and thereby pulls the inner pivot bearing of the first main scissors 4a with. As a result, the first main scissors 4 a are also pulled apart, and the edge protection strip 3 approaches the edge 2. Conversely, this movement causes the outer pivot bearing of the first main scissors 4 a to move outward, and the connecting element pulls the inner pivot bearing of the second main scissors and thereby also causes a crushing of the second main scissors 4 b.

- FIG. 6a and 6b now show an edge protection device with additional scissors, which are hereinafter referred to as middle shears 4c, 4d, ....
- Such middle shears 4c, 4d, ... serve to reduce the buckling length of the edge protection strip 3 and are arranged between the two outer main shears 4a and 4b.
- These middle shears 4c, 4d, ... are connected to the connecting elements 10 ', 10 "in the same sense as the main shears 4a, 4b, that is to say they are also coupled in a motion-parallel manner as are the main shears 4a, 4b.
- 4d is analogous to the main scissors 4a, 4b.
- FIG. 6a and 6b illustrated center shears 4c described in detail.

- the naming of the pivot bearing is analogous to the main shears 4a, 4b.
- the center scissors 4c is coupled with the outer main scissors 4a, 4b via a parallel steering mechanism in such a way that they are parallel to each other in motion such that the edge protection strip 3 is aligned or guided or displaceable or movable parallel to the edge 2.
- the pivot bearings 8, 9 of the center shears 4 c, 4 d .... can no longer be identified by the words "inside” or "outside”, but are essentially equivalent. In analogy to the figures shown before, however, the nomenclature of the outer or inner pivot bearings is retained for reasons of distinction.
- the edge protection strip 3 is also fastened in the edge guard side pivot bearing 7c of the center shears 4c, wherein this attachment can also be omitted and the pivot bearing 7c can be provided only as a stiffener against external pressure.
- the parallel coupling takes place via the connecting elements 10 ', 10 ".
- the first connecting element 10 ' is fastened to the pivot bearing 8c of the center shears 4c.
- the other opposing pivot bearing 9c is guided in an elongate recess 15 '.
- This recess 15 ' is the same as the recess 12' is formed.
- Fig. 6b now shows the edge protection device Fig. 6a without the connecting element 10 '.
- the second connecting element 10 " which is fastened on the other side of the main shears 4a, 4b, can be seen, and the second connecting element 10" is also fastened on the other side of the central shears 4c, namely in the other pivot bearing 9c. It likewise has an elongate recess 15 ", into which recess 15" engages the opposite pivot bearing 8c and is linearly guided therein.
- the connecting elements 10 'and 10 "coordinate the movements in the same direction of the pivot bearings of the different scissors 4a, 4b, 4c with one another pointing in the opposite direction, but also in the same direction, upward movement.
- handlebars 11c, 11d .... may be arranged.
- An angle ⁇ is formed between the scissor segments 5a, 5b, 5c, specifically on the edge-protection-side pivot bearing 7a, 7b and 7c.
- This angle ⁇ changes during the movement of the edge protection device. All angles within a pair of scissors 4 change in the way that is mandatory in a pivotable rhombus or a pivotable parallelogram. When compressing the edge protection device, for example when hitting an obstacle, the angle ⁇ is greater until it is almost 180 °, when opening or relaxing the edge protection device again smaller.
- the movement of the shears 4 should now be limited such that the angle ⁇ in the uncompressed starting position is between> 0 ° and ⁇ 120 °, wherein the angle ⁇ in this initial position is in particular between 3 ° and 20 °.
- Such a limitation of the movement of the shears 4 can be effected either by the recesses 12 or by mechanical limiting elements 16a, 16b.
- Such limiting elements 16a, 16b may be either rigid bars or flexible ropes, as shown in FIG Fig. 5a, 5b is shown. Stiff limiting elements act in both directions limiting, flexible limiting elements only in one.
- the limiting elements 16a, 16b can be designed such that the edge protection device can only be compressed to a certain position, that the edge protection device can be opened to a maximum position or that it can only be moved back and forth within a certain range.
- Such means may be spring means 14, in particular tension or compression springs.
- spring means 14 are shown.
- Fig. 3a is a single spring means and in Fig. 3b provided two spring means.
- These spring means 14 are arranged between the connecting elements 10 'and 10 ", so that the connecting elements 10' and 10" are connected to one another via these spring means 14 or are in relation to each other in the axial direction relative movement at a constant distance between the parallel connecting elements 10 ', In an axial Relatiwerschiebung the two connecting elements 10 'and 10 "against each other, ie when a connecting element 10' is moved upward and the other connecting element 10" down, always parallel to each other, then causes the spring means 14, that the two connecting elements 10 ', 10 "return to their original position. The movement of the connecting elements 10 'and 10 "in turn, as described previously, causes a movement of the scissors 4 and thus the entire edge protection device.
- spring means 14 shown are tension springs.
- the spring means 14 are in a compressed and defined biased state. If now the edge protection device is compressed, the outer pivot bearings 8 move away from the inner pivot bearings 9 as described, and this also causes an upward movement of the second connecting element 10 "and a downward movement of the first connecting element 10 ' If the pressure then leaves on the edge protection device, the spring 14 contracts and the connecting elements 10 'and 10 "are set back into their initial position, which is equivalent to a return movement of the edge protection device or the edge protection strip 3 into their starting position ,
- the compression springs 14 can also extend from the outer or the inner pivot bearings 8, 9 to the edge 2 or the edge protection strip 3.
- the spring effect or the direction of the spring action of the spring means extends in an axis parallel to the edge protection strip 3 or at an angle to the edge protection strip 3, which decreases in the direction of the edge 2 during the movement of the edge protection strip 3.
- edge protection strip 3 When the edge protection strip 3 impinges on an obstacle, a force of approximately 25 to 200 N but at most 1400 N is first exerted on the obstacle because of the prestressing of the spring means. This force is measured by a detection device, which causes a shutdown or a reversal of movement of the edge 2 or the sliding door. This is still done with a certain time delay, which also results in a certain follow-up path of the dangerous edges 2. The edge protection strip 3 or the edge protection device now grant this certain overtravel without endangering safety.
- the edge protection strip 3 therefore only exerts a normally permissible, low-pressure, low force pressure on an obstacle, such as e.g. a body.
- the spring means 14 are biased with a force of 5 N / mm to 400 N / mm, in particular from 10 N / mm to 150 N / mm or have a spring constant of 0.5 N / mm to 5 N / mm, in particular of 1 N / mm to 3 N / mm, on.
- additional additional main shears 4a ', 4b', 4a ", 4b" may be provided. These additional main shears 4a ', 4b' ... are arranged next to the original two main shears 4a, 4b. A preferred arrangement is that the additional main shears 4a ', 4b' ... are parallel to the main shears 4a, 4b.
- the pivot bearings 6, 7, 8, 9 of the main shears 4a, 4b are advantageously aligned in the pivot bearings of the additional main shears or are identical to the pivot bearings 6, 7, 8, 9 of the additional main shears or are on common axes. The same also applies to additional sibling or parallel arranged middle shears 4c ', 4d'.
- Fig. 7a and 7b show such an edge protection device with an additional main scissors 4a 'and 4b'.
- additional shear elements 5a ' are fastened on the left side of the main scissors 4a.
- These additional shearing elements 5a ' represent an additional, although not complete, additional main shears 4a'.
- the additional main shears 4a 'and the original main shears 4a are mounted on the same common pivot axes 6, 7, 8, 9.
- the second main shears 4b are designed analogously to the first one Fig. 3a and 3b again, the possibility of one or two spring means 14 between the connecting elements 10 'and 10 "provided.
- Fig. 8a to 8e show a further embodiment of the edge protection device.
- an additional main scissors 4a ' is attached to an original main scissors 4a top right.
- the original main scissors 4a has two connecting elements 10 ', 10 "
- the additional main scissors 4a' comprises two Connecting elements, which are also designated 10 'and 10 ".All the connecting elements 10' and 10" of the original main scissors 4a and the additional main scissors 4a 'are arranged parallel to each other.
- the situation is similar for the second main shear 4b, to which an additional main shear 4b 'is attached.
- the pivot axes 6, 7, 8, 9 are also common here.
- the arrangement of the spring means 14, as shown in the Fig. 8a to 8e is shown, vary.

- Fig. 10 shows an embodiment with four sibling scissors, a main scissors 4a, a right next to arranged additional main scissors 4a ', another additional main scissors 4a "and still another additional main scissors 4a”'.
- the scissors 4a, 4a 'and 4a “are complete and each have three shear segments 5 as well as a respective link 11a, 11a' and 11a".
- the rightmost additional main scissors 4a "'has a handlebar 11a'" on.
- the error means 14 are in turn arranged arbitrarily between the connecting elements 10 ', 10 ".
- the Fig. 11a and Fig. 11b show a further embodiment of an edge protection device, in which two scissors, a main scissors 4a and an additional main scissors 4a 'are interconnected via webs 17a. These webs 17a are aligned with the axes 6, 7, 8, 9. The webs 17a, 17b serve to increase the distance or as a spacer between the main scissors 4a and the additional main scissors 4a '.
- the webs 17a and 17b can be formed as axes and thus cause a uniform movement of adjacent scissors.
- Fig. 12a and 12b a further embodiment of an edge protection device is shown, the in Fig. 11a, 11b shown embodiment comes very close. In contrast, however, are the handlebars 11a, 11a 'of the main scissors 4a and the auxiliary scissors 4a' inside and the shear segments 5a and 5a 'outside.

Abstract
Description
Die Erfindung betrifft eine Kantenschutzvorrichtung gemäß dem Oberbegriff des Anspruches 1.The invention relates to an edge protection device according to the preamble of claim 1.
Kantenschutzvorrichtungen zur Montage an beweglichen Gegenständen, Insbesondere an Kanten, beispielsweise von sich schließenden Schiebetüren bzw. Lifttüren od. dgl., als Anlauf- bzw. Einklemmsicherung sind bekannt. Derartige Kantenschutzvorrichtungen verhindern beim Anlaufen der Kante bzw. der Kantenschutzvorrichtung an bzw. gegen ein Hindernis Verletzungen oder Beschädigungen.Edge protection devices for mounting on moving objects, in particular on edges, for example, from closing sliding doors or lift doors od. Like., As tarnish or trapping are known. Such edge protection devices prevent injury or damage when starting the edge or the edge protection device on or against an obstacle.
So sind beispielsweise Sicherungssysteme für Lifttüren bekannt, bei denen eine Kantenschutzleiste vorgesehen ist, die über zwei zueinander parallele gerade Führungsstangen an der Kante befestigt ist. Die Führungsstangen sind an ihren beiden Enden schwenkbar gelagert, wodurch eine zwingende Parallelführung zwischen der Kantenschutzleiste und der Kante gewährleistet ist. Allerdings erfolgt dadurch ebenfalls zwingend eine der Länge der Führungsstangen entsprechende Relativbewegung der Kantenschutzleiste bezüglich der Kante d.h. die Kantenschutzleiste wird parallel gegenüber der Kante versetzt und entweder angehoben oder abgesenkt.For example, security systems for lift doors are known in which an edge protection strip is provided, which is fastened to the edge via two parallel straight guide rods. The guide rods are pivotally mounted at both ends, whereby a compelling parallel guidance between the edge protection strip and the edge is ensured. However, a relative movement of the edge protection strip with respect to the edge, which corresponds to the length of the guide rods, likewise necessarily ensues. the edge protection strip is offset parallel to the edge and either raised or lowered.
Derartige Vorrichtungen sind beispielsweise aus der
Aufgabe der Erfindung ist es daher, eine alternative Kantenschutzeinrichtung zu schaffen, die unter Vermeidung des besagten Nachteils eine Bewegung der Kantenschutzleiste in einer Höhe bzw. Ebene mit der Kante bzw. der Türe und ohne höhenmäßige Relativverschiebung gewährleistet.The object of the invention is therefore to provide an alternative edge protection device, which ensures a movement of the edge protection strip in a height or level with the edge or the door and without heightwise relative displacement while avoiding the said disadvantage.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is solved by the characterizing features of claim 1.
Die kennzeichnenden Merkmale des Anspruches 1 haben den Vorteil, dass beim Einbau der Kantenschutzleiste keine Rücksicht auf eine eventuelle höhenmäßige Relativbewegung der Kantenschutzleiste bezüglich der Kante genommen werden muss. Die Kantenschutzleiste bewegt sich unter Beibehaltung der parallelen Ausrichtung auf die Kante zu, eine Versetzung nach oben oder nach unten erfolgt nicht. Dies erleichtert den Einbau und vereinfacht die Konstruktion. Außerdem werden so Gefahrenstellen vermieden, die durch die höhenmäßige Relativbewegung der Kantenschutzleiste entstehen können. Außerdem wird durch die erfindungsgemäße Kantenschutzvorrichtung ein Nachlaufweg gegeben, innerhalb dem die sich schließende Türe bzw. Kante zum Halt kommen muss.The characterizing features of claim 1 have the advantage that when installing the edge protection strip no consideration must be taken to a possible height-related relative movement of the edge protection strip with respect to the edge. The edge protection bar moves towards the edge while maintaining the parallel orientation, an upward or downward shift does not occur. This facilitates installation and simplifies the construction. In addition, so danger spots are avoided, which can be caused by the height relative movement of the edge protection strip. In addition, by the edge protection device according to the invention given a caster, within which the closing door or edge must come to a halt.
Dadurch wird eine konstruktiv vorteilhafte Ausführungsform der Mittel zur Befestigung der Kantenschutzleiste geschaffen. Die so ausgebildeten Mittel sind stabil und langlebig und gewährleisten die parallele Führung der Kantenschutzleiste.As a result, a structurally advantageous embodiment of the means for fixing the edge protection strip is created. The means thus formed are stable and durable and ensure the parallel guidance of the edge protection strip.
Aus Gründen der Gewichtsersparnis ist es vorteilhaft, die Merkmale des Anspruchs 2 vorzusehen. Diese Ausführungsform ist konstruktiv derart gestaltet, dass eine dauerhafte Betätigung möglich ist und die konstruktive Stabilität verbessert wird.For reasons of weight saving, it is advantageous to provide the features of
Eine weitere vorteilhafte Ausführungsform wird durch die Merkmale des Anspruchs 3 definiert. Hierbei ist einerseits zwar das Gewicht etwas höher, jedoch ist man in der Wahl der Verbindungsmittel nicht auf verwindungssteife Verbindungsmittel eingeschränkt, sondern es können auch flexible Verbindungselemente verwendet werden.A further advantageous embodiment is defined by the features of
Zur Verringerung der Knicklänge der Kantenschutzleiste ist es vorteilhaft, wenn die Merkmale des Anspruchs 4 vorgesehen sind. Die Vorteile der vorhergehenden Ansprüche werden hier beibehalten. Konstruktiv sind die zusätzlichen Scheren in Analogie zu den Hauptscheren aufgebaut und gestaltet.To reduce the buckling length of the edge protection strip, it is advantageous if the features of
Um eine optimale Bewegung der Kantenschutzvorrichtung zu gewährleisten, ist es vorteilhaft, wenn die Winkelangaben des Anspruchs 6 eingehalten werden. Eine Auswahl an unterschiedlich wirkenden Verbindungselementen wird auch durch die Ansprüche 7 und 8 gestattet. Je nach Anwendung und nach Anzahl der Verbindungselemente kann unterschiedlich gewählt werden.In order to ensure optimum movement of the edge protection device, it is advantageous if the angle specifications of
Um ein Abkippen bzw. "Herunterfallen" der Kantenschutzleiste im Betrieb zu verhindern, ist es vorteilhaft, wenn die Merkmale des Anspruchs 9 vorgesehen sind. Dadurch wird auf konstruktiv einfache Art vermieden, dass es zu einer höhenmäßigen Relativbewegung bzw. -verstellung kommt und es wird die Parallelführung der Kante bei horizontaler Schließung der Türe gewährleistet.In order to prevent tilting or "dropping" of the edge protection strip in operation, it is advantageous if the features of
Um die Kantenschutzleiste in ihre Ausgangsposition zurückstellen zu können, ist es vorteilhaft, wenn die Merkmale des Anspruchs 10 vorgesehen sind. Die Federn können an unterschiedlichen Stellen angeordnet werden. Vorteilhaft ist hierbei, dass es zu einer Degression der Federkraft beim Zusammendrücken der Kantenschutzvorrichtung kommt.In order to reset the edge protection strip in its original position, it is advantageous if the features of
Das Zusammendrücken der Kantenschutzleiste übt auf bewegte Kanten beim Auftreffen auf ein Hindernis zunächst eine große Kraft aus, die von Detektionsmitteln erfasst wird und ein Stillsetzen bzw. eine Bewegungsumkehr der bewegten Kante einleitet und bewirkt. Da jedoch massive und schwere Türen bzw. Kanten relativ lange Nachlaufwege haben, gewährt nun die Kantenschutzleiste der bewegten Kante eben diesen ausreichenden Nachlaufweg, sodass auch große Massen innerhalb der gegebenen Sicherheitsnormen zum Stillstand gebracht werden können, ohne auf das eingeklemmte Hindernis eine zu große Kraft auszuüben. Durch das Zusammenspiel der Federwirkung in der beschriebenen Richtung und der Einwirkung der äußeren Kräfte senkrecht dazu über die Scheren, wird zum Ende der Bewegung hin eine starke Degression der Kraft erreicht, die die gedrückte Kante nach außen abgibt. Die Türe bzw. das Tor muss in der geschlossenen Stellung nicht verriegelt werden, da die Restkraft der Kantenschutzvorrichtung nicht ausreicht, um es aufzudrücken.The compression of the edge protection strip initially exerts a large force on moving edges when hitting an obstacle, which force is detected by detection means and initiates and effects the stopping or reversing of movement of the moving edge. However, since massive and heavy doors or edges have relatively long overtravel, now the edge protection ledge of the moving edge just this sufficient overtravel, so that even large masses within the given safety standards can be brought to a standstill without the trapped obstacle to exert too much force. Due to the interaction of the spring action in the described direction and the action of the external forces perpendicular thereto via the scissors, a strong degression of the force is achieved toward the end of the movement, which emits the depressed edge to the outside. The door or the gate must not be locked in the closed position, since the residual force of the edge protection device is not sufficient to press it.
Zur Stabilisierung der Kantenschutzleiste gegen seitliche Kraftangriffe ist es vorteilhaft, wenn die Merkmale der Ansprüche 11 und/oder 12 vorgesehen sind.To stabilize the edge protection strip against lateral force attacks, it is advantageous if the features of claims 11 and / or 12 are provided.

Die Kantenschutzleiste 3 ist über die beiden Hauptscheren 4a, 4b an der Kante 2 der Türe, z.B. einer Schiebetüre, Hubtüre, Lifttüre oder Brandschutztüre, befestigt. Die Hauptscheren 4a, 4b befinden sich in relativ äußerer bzw. endständiger Position bezüglich zur Kantenschutzleiste 3. Die Hauptscheren 4a, 4b besitzen die Form einer verschwenkbaren Raute bzw. eines Quadrats. Diese Form ist scherengitterartig verschwenkbar bzw. beweglich.The
Die erste Hauptschere 4a ist genauso wie die zweite Hauptschere 4b aus vier miteinander schwenkbar bzw. gelenkig verbundenen Hauptscherensegmenten 5a aufgebaut. Diese Hauptscherensegmente 5a sind über Schwenklager bzw. Schwenklagerzapfen 6a, 7a, 8a, 9a zu dem besagten verschwenkbaren Parallelogramm verbunden. So sind ein der Kantenschutzleiste 3 fernes bzw. abgewendetes kantenseitiges, d.h. der Kante 2 nahes, Schwenklager 6a, ein der Kantenschutzleiste 3 nahes bzw. zugewendetes kantenschutzleistenseitiges Schwenklager 7a, ein innen angeordnetes bzw. nach innen weisendes, der benachbarten Hauptschere 4b zugewendetes, inneres Schwenklager 9a und ein außen angeordnetes bzw. nach außen weisendes, der benachbarten Hauptschere 4b abgewendetes äußeres Schwenklager 8a vorgesehen. Über das kantenseitige Schwenklager 6a ist die Hauptschere 4a an der Kante 2 befestigbar. Über das kantenschutzleistenseitige Schwenklager 7a ist die Kantenschutzleiste 3 mit der Hauptschere 4a verbunden. Dazu anlog ist die zweite äußere Hauptschere 4b aufgebaut.The first main scissors 4a is constructed, like the second
Die beiden inneren Schwenklager 9a, 9b der beiden Hauptscheren 4a, 4b weisen nach innen zueinander bzw. sind benachbart angeordnet. Die beiden äußeren Schwenklager 8a, 8b weisen jeweils nach oben bzw. nach unten.The two
Die beiden Hauptscheren 4a, 4b sind über einen Parallellenkmechanismus derart miteinander bewegungsparallel gekoppelt, dass die Kantenschutzleiste 3 ausschließlich eine senkrecht zur Kante 2 ausgerichtete Verschiebung bzw. Bewegung vollziehen kann, wobei die Kantenschutzleiste 3 während ihrer Bewegung in Richtung der Kante 2 bzw. weg von der Kante 2 ständig parallel zur Kante 2 ausgerichtet bleibt. Es erfolgt eine Parallelverschiebung der Kantenschutzleiste 3 in senkrechter Richtung zur Kante 2.The two
Als Parallellenkmechanismus dienen gemäß
Eigentlich wäre ein einziges derartiges, als Zug- und Druckmittel wirkendes, Verbindungselement 10 ausreichend, um eine Parallelführung der Bewegung der beiden Hauptscheren 4a, 4b zu bewirken. Es ist essentiell, dass dieses Verbindungselement 10 das äußere Schwenklager 8a, 8b der einen Hauptschere 4a, 4b mit dem inneren Schwenklager 9b, 9a der anderen Hauptschere 4b, 4a verbindet.Actually, a single such, acting as tension and pressure means, connecting
Auf diese Weise sind alle äußeren bzw. inneren Schwenklager 8, 9 mit Verbindungselementen 10', 10" verbunden. Die Verbindungselemente 10' und 10" liegen parallel ausgerichtet zueinander.In this way, all the outer or
Auf diese Weise ist es der Kantenschutzvorrichtung möglich, eine Bewegung gemäß
Zur Verdeutlichung ist links neben den Figuren eine Darstellung des Verbindungselementes 10', 10" in seiner jeweiligen Position wiedergeben. Erkennbar ist, dass die Kantenschutzleiste 3 ohne Versetzung nach oben oder unten zur Kante 2 verschoben wird. Auch wenn der Kraftangriff auf die Kantenschutzleiste 3 in einem extremen unteren oder oberen Bereich erfolgt, muss die Bewegung der Kantenschutzleiste 3 zwingend parallel zur Kante 2 geführt sein.For clarification, a representation of the connecting
Um zusätzliche Führungsstabilität zu gewährleisten, ist im ersten Verbindungselement 10' eine längliche Ausnehmung 12' vorgesehen und im zweiten Verbindungselement 10" eine längliche Ausnehmung 12". Die längliche Ausnehmung 12' ist im Bereich des freien, nicht mit dem ersten Verbindungselement 10' verbundenen, inneren Schwenklagers 9b der zweiten Hauptschere 4b ausgebildet. Das freie innere Schwenklager 9b greift in die Ausnehmung 12' ein und ist darin geführt bzw. gelagert. Die Ausnehmung 12' weist eine Länge auf, die der Versetzung bzw. Bewegung des Schwenklagers 9b entspricht. Dadurch werden auch die maximal möglichen Bewegungen der Kantenschutzleiste 3 bzw. die maximalen Wege begrenzt. Sobald das Schwenklager 9b in einer unteren Extremposition der länglichen Ausnehmung 12' angekommen ist, stoppt die Bewegung der Kantenschutzleiste 3.In order to ensure additional guiding stability, an elongate recess 12 'is provided in the first connecting element 10' and an
Im zweiten Verbindungselement 10" ist die längliche Ausnehmung 12" im Bereich des freien, nicht mit dem zweiten Verbindungselement 10" verbundenen inneren Schwenklager 9a der ersten Hauptschere 4a ausgebildet. Dieses freie innere Schwenklager 9a greift in die Ausnehmung 12' ein und ist darin linear geführt. In
In allen
Jede Schere 4a, 4b, 4c kann einen oder mehrere derartige Lenker 11a, 11b, 11c,... aufweisen. Ausreichend wäre im Prinzip ein einziger Lenker 11 für die gesamte Kantenschutzvorrichtung, da die Scheren 4a, .... ohnehin bewegungsparallel gekoppelt sind.Each pair of
Für alle Ausführungsformen gilt: Beim Zusammendrücken der Kantenschutzvorrichtung wandern die inneren Schwenklager 9a und 9b aufeinander zu und die äußeren Schwenklager 8a, 8b voneinander weg. Die kantenseitigen Schwenklager 6a, 6b und die kantenschutzleistenseitigen Schwenklager 7a, 7b nähern sich in einer geraden Linie aneinander an. Die Lenkerköpfe 13a, 13b wandern ebenfalls aufeinander zu.For all embodiments, when the edge protection device is compressed, the
Durch das Verbindungselement 10' wird die Bewegung des inneren Schwenklagers 9a auf das äußere Schwenklager 8b der zweiten Hauptschere 4b übertragen und dieses Schwenklager 8b dadurch nach außen gedrückt. Selbiges geschieht mit dem zweiten Verbindungselement 10". Das äußere Schwenklager 8a der ersten Hauptschere 4a wandert nach außen und zieht dadurch das innere Schwenklager 9b der zweiten Hauptschere 4b mit und nach innen.By the connecting element 10 ', the movement of the inner pivot bearing 9a is transmitted to the outer pivot bearing 8b of the second
In
Zur Begrenzung der Bewegung dienen in diesem Fall Begrenzungselemente 16a, 16b. Diese sind hier als Seile ausgebildet, die die kantenseitigen Schwenklager 6a, 6b mit den kantenschutzleistenseitigen Schwenklagern 7a, 7b verbinden. Die maximale Bewegung der Kantenschutzleiste 3 kann sich nicht über die maximale Länge der Begrenzungselemente 16a, 16b erstrecken. Derartige Begrenzungselemente 16a, 16b könnten auch direkt von der Kante 2 bis zur Kantenschutzleiste 3 geführt sein oder sich beispielsweise von der Kante 2 bis zu einem der äußeren oder inneren Schwenklager erstrecken.To limit the movement serve in this case limiting elements 16a, 16b. These are designed here as ropes which connect the edge-side pivot bearings 6a, 6b with the edge protection strip
Im folgenden wird die in
Die Benennung der Schwenklager erfolgt analog zu den Hauptscheren 4a, 4b. Die Mittelschere 4c ist mit den äußeren Hauptscheren 4a, 4b über einen Parallellenkmechanismus derart miteinander bewegungsparallel gekoppelt, dass die Kantenschutzleiste 3 parallel zur Kante 2 ausgerichtet bzw. geführt bzw. verschiebbar bzw. bewegbar ist. Die Schwenklager 8, 9 der Mittelscheren 4c, 4d .... können nicht mehr durch die Wörter "innen" oder "außen" gekennzeichnet werden, sondern sich im wesentlichen gleichwertig. In Analogie zu den davor gezeigten Fig. wird jedoch die Nomenklatur der äußeren oder inneren Schwenklager aus Unterscheidungsgründen beibehalten.The naming of the pivot bearing is analogous to the
Die Kantenschutzleiste 3 ist auch im kantenschutzleistenseitigen Schwenklager 7c der Mittelschere 4c befestigt, wobei diese Befestigung auch weggelassen werden kann und das Schwenklager 7c lediglich als Versteifung gegen äußeren Druck vorgesehen sein kann. Die Parallelkopplung erfolgt über die Verbindungselemente 10', 10".The
Das erste Verbindungselement 10' ist am Schwenklager 8c der Mittelschere 4c befestigt. Das andere gegenüberliegende Schwenklager 9c ist in einer länglichen Ausnehmung 15' geführt. Diese Ausnehmung 15' ist gleich wie die Ausnehmung 12' ausgebildet.The first connecting element 10 'is fastened to the pivot bearing 8c of the center shears 4c. The other opposing pivot bearing 9c is guided in an elongate recess 15 '. This recess 15 'is the same as the recess 12' is formed.
Auch an den Mittelscheren 4c, 4d können Lenker 11c, 11d .... angeordnet sein.Also on the middle shears 4c, 4d handlebars 11c, 11d .... may be arranged.
Zwischen den Scherensegmenten 5a, 5b, 5c, und zwar am kantenschutzseitigen Schwenklager 7a, 7b und 7c ist ein Winkel α ausgebildet. Dieser Winkel α verändert sich bei der Bewegung der Kantenschutzvorrichtung. Sämtliche Winkel innerhalb einer Schere 4 verändern sich auf die Weise, wie dies in einer verschwenkbaren Raute bzw. einem verschwenkbaren Parallelogramm zwingend vorgegeben ist. Beim Zusammendrücken der Kantenschutzvorrichtung, beispielsweise beim Auftreffen auf ein Hindernis, wird der Winkel α größer, bis dieser fast 180° beträgt, beim Öffnen bzw. Entspannen der Kantenschutzvorrichtung wieder kleiner.An angle α is formed between the
Die Bewegung der Scheren 4 sollte nun derart begrenzt sein, dass der Winkel α in der nicht zusammengedrückten Ausgangsposition zwischen >0° und ≤ 120° beträgt, wobei der Winkel α in dieser Ausgangsposition insbesondere zwischen 3° und 20° beträgt. Eine derartige Begrenzung der Bewegung der Scheren 4 kann entweder durch die Ausnehmungen 12 oder durch mechanische Begrenzungselemente 16a, 16b bewirkt werden. Derartige Begrenzungselemente 16a, 16b können entweder steife Stangen oder flexible Seile sein, wie dies in
Für eine erfolgreiche Bewegung der Kantenschutzvorrichtung ist es vorteilhaft, wenn Mittel zur Rückstellung bzw. Rückbewegung der Kantenschutzleiste 3 in ihre von der Kante 2 beabstandete Ausgangsposition vorgesehen sind. Derartige Mittel können Federmittel 14, insbesondere Zug- oder Druckfedern sein. In
Bei den in
Die Druckfedern 14 können auch von den äußeren bzw. den inneren Schwenklagern 8, 9 zur Kante 2 oder zur Kantenschutzleiste 3 hin verlaufen.The compression springs 14 can also extend from the outer or the
Die Federwirkung bzw. die Richtung der Federwirkung der Federmittel verläuft in einer Achse parallel zur Kantenschutzleiste 3 oder in einem Winkel zur Kantenschutzleiste 3, der sich bei der Bewegung der Kantenschutzleiste 3 in Richtung zur Kante 2 verringert. Dadurch wird im Zusammenspiel mit den Scheren eine Degression der die Kantenschutzleiste 3 nach außen drückenden Kraft erreicht. Die Gegenkraft wird umso schwächer je stärker die Kantenschutzvorrichtung zusammengedrückt wird, mit überproportional starkem Abfall der Gegenkraft beim Erreichen der Endlage in vollständig zusammengedrücktem Zustand. Die Kraft nimmt in erster Näherung mit dem Cotangens des halben Winkels α ab.The spring effect or the direction of the spring action of the spring means extends in an axis parallel to the
Beim Auftreffen der Kantenschutzleiste 3 auf ein Hindernis wird wegen der Vorspannung der Federmittel zunächst eine Kraft von ca. 25 bis 200 N höchstens jedoch 1400 N auf das Hindernis ausgeübt. Diese Kraft wird von einer Detektionseinrichtung gemessen, wodurch ein Stillsetzen oder eine Bewegungsumkehr der Kante 2 bzw. der Schiebetüre verursacht wird. Diese erfolgt noch mit einer gewissen Zeitverzögerung, wodurch sich auch ein gewisser Nachlaufweg der gefährlichen Kanten 2 ergibt. Die Kantenschutzleiste 3 bzw. die Kantenschutzvorrichtung gewähren nun diesen gewissen Nachlaufweg ohne die Sicherheit zu gefährden. Durch das Zusammenspiel der Federwirkung in der beschriebenen Richtung und der Einwirkung der Kräfte senkrecht dazu über die Scheren wird zum Ende der Bewegung, d.h. bei starkem Zusammendrücken der Kantenschutzvorrichtung eine starke Degression der Kraft erreicht, die die gedrückte Kantenschutzleiste 3 auf das Hindernis ausübt.When the
Daraus ergibt sich weiters der Vorteil, dass bei einer Türe, die geschlossen ist und bei der die Kantenschutzvorrichtung zusammengedrückt ist, die Restkraft der Kantenschutzvorrichtung nicht ausreicht, die Türe aufzudrücken.This also results in the advantage that when a door is closed and in which the edge protection device is compressed, the residual force of the edge protection device is not sufficient to push the door.
Die Kantenschutzleiste 3 übt daher lediglich einen normgemäß zulässigen bzw. für Menschen ungefährlichen, geringen Kraftdruck auf ein Hindernis, wie z.B. einen Körper aus.The
Die Federmittel 14 sind mit einer Kraft von 5 N/mm bis 400 N/mm, insbesondere von 10 N/mm bis 150 N/mm vorgespannt bzw. weisen eine Federkonstante von 0,5 N/mm bis 5 N/mm, insbesondere von 1 N/mm bis 3 N/mm, auf.The spring means 14 are biased with a force of 5 N / mm to 400 N / mm, in particular from 10 N / mm to 150 N / mm or have a spring constant of 0.5 N / mm to 5 N / mm, in particular of 1 N / mm to 3 N / mm, on.
Zur Stabilisierung der Kantenschutzleiste 3 bzw. der Kantenschutzvorrichtung gegen zumindest teilweise seitliche Kraftangriffe können zusätzliche Zusatzhauptscheren 4a', 4b', 4a", 4b" vorgesehen sein. Diese Zusatzhauptscheren 4a', 4b' ... sind neben den ursprünglichen beiden Hauptscheren 4a, 4b angeordnet. Eine bevorzugte Anordnung ist, dass die Zusatzhauptscheren 4a', 4b' ... parallel neben den Hauptscheren 4a, 4b liegen. Die Schwenklager 6, 7, 8, 9 der Hauptscheren 4a, 4b liegen vorteilhafterweise fluchtend in den Schwenklagern der Zusatzhauptscheren oder sind identisch zu den Schwenklagern 6, 7, 8, 9 der Zusatzhauptscheren bzw. liegen auf gemeinsamen Achsen. Selbiges gilt auch für zusätzliche nebengeordnete bzw. parallel angeordnete Mittelscheren 4c', 4d'.To stabilize the

Es sind insgesamt acht zueinander parallele Verbindungselemente 10', 10" vorgesehen. Jede Hauptschere bzw. Zusatzhauptschere 4a, 4a', 4a", 4a"' weist jeweils zwei Verbindungselemente 10', 10" auf. Die Fehlermittel 14 sind wiederum beliebig zwischen den Verbindungselementen 10', 10" angeordnet.A total of eight mutually parallel

Die Stege 17a und 17b können als Achsen ausgebildet werden und somit eine gleichförmige Bewegung nebeneinanderliegender Scheren bewirken.The webs 17a and 17b can be formed as axes and thus cause a uniform movement of adjacent scissors.

Die für die
Weiters sind hier nicht dargestellte Detektionsmittel zur Detektion einer Annäherung der Kantenschutzleiste 3 an die Kante 2 vorgesehen, wobei bei Annäherung gegebenenfalls die Bewegung der Kante 2 bzw. des Gegenstands gestoppt wird. Derartige Detektionsmittel können, wie erwährt, Kraftsensoren sein, die den Kraftanstieg durch Messung des Motorstroms erkennen und danach schalten bzw. die Türbewegung anhalten.Furthermore, detection means, not shown here, are provided for detecting an approach of the
Zur zusätzlichen Sicherung gegen Einklemmungen können weitere Sicherheitseinrichtungen vorgesehen sein. So kann die Kantenschutzleiste 3 beispielsweise im Querschnitt U-förmig ausgebildet sein, wobei die Schenkel der U-förmigen Kantenschutzleiste 3 in Richtung der Kante 2 gezogen sind und somit die Mittel 4a, 4b, 4c,... bzw. Scheren von der Seite nicht mehr zugänglich sind bzw. bei seitlicher Ansicht der Blick auf und der Zugriff in die Mittel 4a, 4b, 4c,... bzw. Scheren versperrt ist. Die Schenkel können bis über den Beginn der Kante 2 weiter gezogen werden, um zusätzliche Sicherheit zu verschaffen.For additional protection against entrapment further safety devices can be provided. Thus, the
Auch kann vorgesehen sein, dass die Mittel 4a, 4b, 4c,... bzw. Scheren in einer nutförmigen, länglichen Ausnehmung in der Kante 2 versenkbar sind. Die Mittel 4a, 4b, 4c,... bzw. Scheren sind in diesem Fall am Boden der Nut befestigt. In zusammengedrücktem Zustand schließt die Kantenschutzleiste 3 mit den beidseitig der Nut aufragenden Kanten ab. Die Mittel 4a, 4b, 4c,... bzw. Scheren werden so im wesentlichen im Inneren der Nut komprimiert.It can also be provided that the
