Definitions
- the invention relates to a sectional lifting gate with segments which are pivotally connected to one another via their end faces and are laterally guided in rails and which, in the open state, can be folded onto one another alternately in the upper edge region of the gate.
- FR-A-957 064 also does not have swivel axes lying on a straight line and a drive realized by a chain and tooth segments engaging therein.
- FR-A-2 352 150 the adjacent segments are separated from one another in order to then line them up next to one another in the same orientation.
- the invention has set itself the task of creating a sectional lifting gate, which, when open, requires little space and yet has the good insulation options known from sectional doors.
- the basic idea of the present invention is the further development of sectional lifting gates in such a way that in the open state they require a minimum of own space, for which purpose the individual segments are folded onto one another alternately, so that a compact package is created.
- the axes, around which neighboring segments are folded relative to each other, are to be attached alternately on the inside and outside in the edge area.
- a rocker arm is attached to the face of at least every second segment via a joint which is parallel to the segments in one Running track is guided.
- the individual rocker arms additionally have toothed segments which engage in a chain running at a distance from the running rail. In this state, the segments are carried along when the chain moves up and down.
- the decisive advantage of the present invention is the addition of the advantages of the sectional door with those of the roller door in that the excellent insulation capacity, the possibility of installing large insulation windows is combined with the freedom of space or the small amount of space required for the roller door in the open state.
- the opening process can be carried out quickly and at a similar speed to that of roller shutters.
- Another important object of the invention is in providing the outside of the closed door with a neutral, homogeneous surface that is not defaced by the fitting of fittings.
- standard hinges can only be used on the inside (and not also on the outside).
- a space joint is proposed that is attached to the end of mutually opposite segments, with the result that when the door is closed and the segments are seated on top of one another, the hinge is completely covered, and yet a fold of 180 degrees around the outer edge allowed to make.
- Man then gets a smooth outer surface on the one hand, which is aesthetically appealing and can be freely chosen in its design, on the other hand it can be folded by 180 degrees. Due to the alternating folding of adjacent segments, only every second hinge has to be designed as a space hinge.
- the running rail receiving the rocker arm at the end provided with the toothed segment has rocker arms, upon reaching which the rocker arm is supported by spring force moves outwards, the driver then leaves the chain and folds up the respective segment too supported and triggers inside. This ensures that the folding takes place only in the area of the rocker arms, ie in the edge area covered by the goal frame to the outside. Otherwise, crushing zones that would cause injury would arise.
- the number of rocker arms corresponds to half the number of segments. Since the rocker arms are supported by leg springs, they return to their starting position when the gate is closed.
- the end of the rocker arm received in the running rails is provided with running rollers located in the running rail, which provide good support, i.e. also guarantee good stability and smooth running.
- adjacent segments are connected to one another via twin joints, which are defined by the fact that they have two parallel to one another Have pivot axes. In order to allow adjacent segments to move by 180 degrees, it is sufficient if each pivot axis of the twin joint can be moved by 90 degrees. When the segments are folded together, a structure that is symmetrical to the central plane of the twin joint is obtained during each movement phase.
- twin joints which are defined by the fact that they have two parallel to one another Have pivot axes.
- each pivot axis of the twin joint can be moved by 90 degrees.
- a structure that is symmetrical to the central plane of the twin joint is obtained during each movement phase.
- One of the decisive advantages of the specified twin joint is the possibility of positioning all swivel axes on a straight line running centrally in the rail (in the most general case this can also be a curved line determined by the course of the rail).
- rollers Both for guiding the segments and the twin joint, it is proposed to arrange rollers on the end of the swivel axes, the rollers on one side being guided in the same rail.
- a particularly favorable drive for the door is given as an example:
- a toothed rocker is attached to the axis of a roller, which is provided with a guide roller at its opposite end.
- the latter is moved in a rail which does not serve to guide the roller and serves to pivot the toothed rocker arm.
- Their task lies in the engagement and coupling of a chain arranged and driven at a short distance.
- the toothed rocker is in engagement, when folding the engagement ends by moving the Toothed rocker and release of the chain.
- the associated guide roller is moved accordingly, ie it is in engagement with the rail until the associated segment is folded up.
- Appropriate decoupling levers take up the guide roller and move it away from the chain, so that the engagement ends. At the same time, the next uncoupling lever is activated, which is used to hold the next guide roller. The common task of the guide roller and the disengagement lever is to end the engagement in the driven chain at the appropriate time.
- the gate (1) is formed in its entirety by all segments (2) arranged one above the other. Adjacent segments are either with one another on the inside located hinge (3) or alternatingly arranged on the front side space hinge (4) in connection, both of which allow the segments (2) to be folded or placed on top of one another.
- the purpose of the hinge (4) is to create a swivel axis in the area of the outer edge of the end face and not to be visible from the outside, so that the door (1) offers a homogeneous exterior view.

- the gate (1) is attached to the masonry (8) and the rail (6) there has rocker arms (9) with which the rocker arms (5) successively and one above the other move the associated segment (2) horizontally Collapse position.
- each rocker arm is actuated by a rocking lever (5) sliding over it and the segment (2) is brought into the horizontal position.
- the movement of the rocker arm (5) outwards causes the toothed segment (7) attached to it to come into engagement with the endless chain which makes the upward and downward movement and is no longer continued.
- the endless chain (10) is set in motion in the usual way via a drive (11).
- Figure 2 shows a longitudinal section through a gate (1) which is fixed in a masonry (8) and the upper four segments (2) are completely or partially folded to the closed position.
- the segments are connected by means of two twin joints (12) which run parallel to one another and allow adjacent segments (2) to be pivoted by a maximum of 180 degrees.
- the shape of the twin joint (12) is chosen so that an outer surface of the gap adjacent segments (2) is closed and covered.
- the opposite surfaces of the same gap are bridged on the outside with a sealing strip (13), the elastic properties of which allow the segments (2) to be folded together. Covering the gap between adjacent segments (2) at least to the outside is of decisive advantage since it forms a pleasant aesthetic surface and at the same time prevents the penetration of moisture.
- FIG. 3 shows the drive of the segment gate proposed in a special embodiment. It has a twin joint (12) which is provided with two guided rollers (14). A toothed rocker arm (15) is attached to the lower roller (14) and is provided with a guide roller (16) at its opposite end.

- the drive takes place via the endless chain (10) by means of the toothed rocker (15) in engagement. Since in the folded state of the segments (2) their position remains fixed, the engagement in the chain (10) must be ended. The position then assumed by the rocker arm (15) can be seen from the rocker arm (15) shown in the upper area. Each decoupling lever (18) is then placed in the rail (17) to receive the guide roller (16) when the decoupling lever (18) above it has gripped the associated guide roller (16).
- the individual decoupling levers are successively brought into the rail (17) from top to bottom and each take up a guide roller (16). Their distance is equal to the distance between adjacent guide rollers (16) when the door is folded.
- each twin joint (12) is connected to the chain (10) via the associated toothed rocker arm (15) and is moved, there is a force distribution to the individual segments and a selective relief.

Abstract
Description
Die Erfindung betrifft ein Sektionalhubtor mit Segmenten, die jeweils über ihre Stirnseiten verschwenkbar miteinader verbunden und seitlich in Schienen geführt sind und die in geöffnetem Zustand im oberen Randbereich des Tores alternierend aufeinander faltbar sind.The invention relates to a sectional lifting gate with segments which are pivotally connected to one another via their end faces and are laterally guided in rails and which, in the open state, can be folded onto one another alternately in the upper edge region of the gate.
Vorrichtungen gattungsgemäßer Art sind aus der FR-A-2 007 661 bekannt geworden, aus der bereits ein Sektionalhubtor mit im Randbereich des Tores alternierend aufeinander faltbaren Segmenten bekannt ist. Zur Sicherstellung der Laufruhe beim Öffnen und Schließen sowie zur Beseitigung weiterer Probleme, bilden benachbarte Segmente einen Winkel unter 180°, so daß die Schwenkachsen einen zick-zackförmigen Verlauf beschreiben. Die Bewegung erfolgt ohne die Verwendung eines direkt an den einzelnen Segmenten angreifenden Kettenantriebes.Devices of the generic type are known from FR-A-2 007 661, from which a sectional lifting gate with segments that can be folded alternately in the edge region of the gate is already known. To ensure smooth running when opening and closing and to eliminate other problems, adjacent segments form an angle below 180 °, so that the pivot axes describe a zigzag course. The movement takes place without the use of a chain drive that directly engages the individual segments.
Die FR-A-957 064 kennt ebenfalls nicht auf einer Gerade liegende Schwenkachsen sowie einen durch eine Kette und darin angreifende Zahnsegmente realisierten Antrieb. In der FR-A-2 352 150 schließlich werden die benachbarten Segmente voneinander getrennt, um sie anschließend nebeneinander in gleicher Ausrichtung aufzureihen.The FR-A-957 064 also does not have swivel axes lying on a straight line and a drive realized by a chain and tooth segments engaging therein. Finally, in FR-A-2 352 150, the adjacent segments are separated from one another in order to then line them up next to one another in the same orientation.
Hiervon ausgehend hat sich die Erfindung die Schaffung eines Sektionalhubtores zur Aufgabe gemacht, welches in geöffnetem Zustand einen geringen Eigenplatzbedarf besitzt und trotzdem die von den Sektionaltoren her bekannten guten Isolationsmöglichkeiten aufweist.Proceeding from this, the invention has set itself the task of creating a sectional lifting gate, which, when open, requires little space and yet has the good insulation options known from sectional doors.
Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß im geschlossenen Zustand sämtliche Schwenkachsen zwischen benachbarten Segmenten auf einer in der Mitte der Schiene verlaufenden Geraden liegen und jedes zweite Segment mit einem Schwinghebel verbunden ist, dessen eines Ende in der Schiene geführt und mit einem Zahnsegment versehen ist, das in eine parallel zur Schiene verlaufende, angetriebene Kette eingreift, wobei die Schwinghebel zum Aufeinanderfalten der Segmente sukzessive verschwenkt werden.This object is achieved according to the invention in that in the closed state all pivot axes between adjacent segments lie on a straight line running in the middle of the rail and every second segment is connected to a rocker arm, one end of which is guided in the rail and is provided with a toothed segment, which engages in a driven chain running parallel to the rail, the rocking levers being successively pivoted to unfold the segments.
Der Grundgedanke vorliegender Erfindung ist die Weiterentwicklung von Sektionalhubtoren dahingehend, daß sie in geöffnetem Zustand ein Minimum an Eigenplatzbedarf erfordern, wozu die einzelnen Segmente alternierend aufeinander gefaltet werden, so daß ein kompaktes Paket entsteht. Die Achsen, um welche benachbarte Segmente relativ gegeneinander gefaltet werden, sind alternierend auf der Innen- und Außenseite im Kantenbereich anzubringen.The basic idea of the present invention is the further development of sectional lifting gates in such a way that in the open state they require a minimum of own space, for which purpose the individual segments are folded onto one another alternately, so that a compact package is created. The axes, around which neighboring segments are folded relative to each other, are to be attached alternately on the inside and outside in the edge area.
Um für das gesamte Tor beim Zusammen- und Entfalten aufgrund der zurückzulegenden unterschiedlichen Wege im geometrischen Sinne ein ruckartiges unerwünschtes Verhalten zu vermeiden, also eine hohe Laufruhe zu erlangen, ist aufgrund geometrischer Überlegungen notwendig, wenn im geschlossenen Zustand sämtliche Schwenkachsen zwischen benachbarten Segmenten auf einer Linie ohne Knickpunkte, also auf einer Geraden liegen. Die Schwenkachsen finden sich nicht mehr auf der Innen- und Außenseite sondern auf einer zentralen, etwa in der Mitte der Schiene verlaufenden Geraden oder bogenförmigen Linie.In order to avoid jerky undesirable behavior for the entire door when folding and unfolding due to the different paths to be covered in the geometrical sense, that is to achieve smooth running, geometric considerations are necessary when in the closed state all swivel axes between adjacent segments lie on a line without break points, i.e. on a straight line. The swivel axes are no longer found on the inside and outside but on a central straight line or curved line running approximately in the middle of the rail.
Um sicherzustellen, daß beim Schließen des Tores die einzelnen Segmente sukzessive und beginnend von dem im Randbereich des Tores sitzenden äußersten ausgehend, zusammengefaltet werden, ist an der Stirnseite zumindest jedes zweiten Segments ein Schwinghebel über ein Gelenk befestigt ist, welcher parallel zu den Segmenten in einer Laufschiene geführt wird. Gleichzeitig weisen die einzelnen Schwinghebel zusätzlich Zahnsegmente auf, die in eine im Abstand zur Laufschiene verlaufende Kette eingreift. In diesem Zustand werden die Segmente bei der Auf- und Abwärtsbewegung der Kette mitgeführt.In order to ensure that when the gate closes, the individual segments are folded together successively, starting from the outermost one in the edge region of the gate, a rocker arm is attached to the face of at least every second segment via a joint which is parallel to the segments in one Running track is guided. At the same time, the individual rocker arms additionally have toothed segments which engage in a chain running at a distance from the running rail. In this state, the segments are carried along when the chain moves up and down.
Der entscheidende Vorzug vorliegender Erfindung besteht in der Addition der Vorteile des Sektionaltores mit denen des Rolltores dadurch, daß das vorzügliche Isolationsvermögen, die Einbaumöglichkeit großflächiger Isolationsfenster verbunden wird mit der Raumfreiheit bzw. dem geringen Eigenraumbedarf des Rolltores im geöffneten Zustand. Der Öffnungsvorgang läßt sich rasch und mit ähnlicher Geschwindigkeit wie bei Rolltoren vornehmen.The decisive advantage of the present invention is the addition of the advantages of the sectional door with those of the roller door in that the excellent insulation capacity, the possibility of installing large insulation windows is combined with the freedom of space or the small amount of space required for the roller door in the open state. The opening process can be carried out quickly and at a similar speed to that of roller shutters.
Ein weiteres wichtiges Ziel der Erfindung besteht darin, das geschlossene Tor an seiner Außenseite mit einer neutralen, homogenen und nicht durch die Anbringung von Beschlägen verunstalteten Oberfläche zu versehen. Demzufolge können nur an der Innenseite (und nicht auch auf der Außenseite) handelsübliche Scharniere eingesetzt werden. Aus diesem Grunde wird in einer zweckmäßigen Weiterbildung der Erfindung ein Raumgelenk vorgeschlagen, daß an der Stirnseite einander gegenüberliegender Segmente angebracht wird mit der Folge, daß bei geschlossenem Tor und aufeinandersitzenden Segmenten das Scharnier völlig verdeckt ist, und dennoch eine Faltung um 180 Grad um die Außenkante vorzunehmen gestattet. Man
erhält dann einerseits eine glatte Außenfläche, die ästhetisch ansprechend ist und in ihrer Gestaltung frei gewählt werden kann, andererseits ist eine Faltung um 180 Grad möglich. Aufgrund alternierenden Zusammenfaltens benachbarter Segmente muß jeweils nur jedes zweite Scharnier als Raumgelenk ausgebildet sein.Another important object of the invention is in providing the outside of the closed door with a neutral, homogeneous surface that is not defaced by the fitting of fittings. As a result, standard hinges can only be used on the inside (and not also on the outside). For this reason, in a practical development of the invention, a space joint is proposed that is attached to the end of mutually opposite segments, with the result that when the door is closed and the segments are seated on top of one another, the hinge is completely covered, and yet a fold of 180 degrees around the outer edge allowed to make. Man
then gets a smooth outer surface on the one hand, which is aesthetically appealing and can be freely chosen in its design, on the other hand it can be folded by 180 degrees. Due to the alternating folding of adjacent segments, only every second hinge has to be designed as a space hinge.
Bei einer Vielzahl konkreter baulicher Realisierungen ergeben sich zwischen den Stirnseiten benachbarter Segmente Spalten und Zwischenräume. In derartigen Fällen empfiehlt sich in besonderer Weise die Anbringung von elastischen Dichtungsstreifen zwischen den Stirnseiten benachbarter Segmente. Deren elastische Eigenschaft ist erforderlich, um das Zusammenfalten zu gestatten. Sie sind vor allem an der Außenseite anzubringen und dienen der Abdichtung und gleichzeitig auch aus ästhetischen Gründen der Schaffung einer homogenen Außenfläche. Falls eine Überbrückung durch die Scharniere möglich ist, wird die Anbringung des Dichtungsstreifens nur bei jeder zweiten Schwenkachse erforderlich sein.In the case of a large number of concrete structural realizations, there are gaps and spaces between the end faces of adjacent segments. In such cases, it is particularly advisable to apply elastic sealing strips between the end faces of adjacent segments. Their elastic properties are necessary to allow the folding. They are primarily to be attached to the outside and are used for sealing and at the same time for aesthetic reasons to create a homogeneous outer surface. If bridging by the hinges is possible, the application of the sealing strip will only be necessary for every second pivot axis.
Zum Zusammenfalten im Randbereich der Öffnung des Tores weist die den Schwinghebel an dem mit dem Zahnsegment versehenen Ende aufnehmende Laufschiene Kipphebel auf, bei deren Erreichen der Schwinghebel unterstützt durch Federkraft sich nach außen bewegt, daraufhin der Mitnehmer die Kette verläßt und das Zusammenfalten des jeweiligen Segmentes nach innen zu unterstützt und aus löst. Hierdurch wird sichergestellt, daß das Zusammenfalten nur im Bereich der Kipphebel, d.h. in dem durch den Torrahmen nach außen abgedeckten Randbereich erfolgt. Andernfalls würden zu Verletzung Anlaß gebende Quetschzonen entstehen.
Die Anzahl der Kipphebel entspricht der halben Anzahl der Segmente. Da die Kipphebel durch Schenkelfeder unterstützt sind, kehren sie beim Verschließen des Tores wieder in ihre Ausgangsposition zurück.For folding in the edge region of the opening of the door, the running rail receiving the rocker arm at the end provided with the toothed segment has rocker arms, upon reaching which the rocker arm is supported by spring force moves outwards, the driver then leaves the chain and folds up the respective segment too supported and triggers inside. This ensures that the folding takes place only in the area of the rocker arms, ie in the edge area covered by the goal frame to the outside. Otherwise, crushing zones that would cause injury would arise.
The number of rocker arms corresponds to half the number of segments. Since the rocker arms are supported by leg springs, they return to their starting position when the gate is closed.
In einer vorteilhaften Ausgestaltung ist das in den Laufschienen aufgenommene Ende des Schwinghebels mit in der Laufschiene befindlichen Laufrollen versehen, die eine gute Abstützung, d.h. auch gute Stabilität und eine laufruhige Führung garantieren.In an advantageous embodiment, the end of the rocker arm received in the running rails is provided with running rollers located in the running rail, which provide good support, i.e. also guarantee good stability and smooth running.
In einer besonders bevorzugten Ausführungsform werden benachbarte Segmente über Zwillingsgelenke miteinander verbunden, die dadurch definiert sind, daß sie zwei parallel zueinander verlaufende Schwenkachsen aufweisen. Um eine Bewegung benachbarter Segmente um 180 Grad zu gestatten, ist es ausreichend, wenn jede Schwenkachse des Zwillingsgelenkes um 90 Grad bewegbar ist. Beim Zusammenfalten der Segmente erhält man während jeder Bewegungsphase ein zur Mittelebene des Zwillingsgelenkes symmetrisches Gebilde. Einer der entscheidenden Vorteile des angegebenen Zwillingsgelenkes besteht in der Möglichkeit der Positionierung sämtlicher Schwenkachsen auf einer zentral in der Schiene verlaufenden Geraden (im allgemeinsten Fall kann es sich hierbei auch um eine durch den Verlauf der Schiene bestimmten gekrümmten Linie handeln).In a particularly preferred embodiment, adjacent segments are connected to one another via twin joints, which are defined by the fact that they have two parallel to one another Have pivot axes. In order to allow adjacent segments to move by 180 degrees, it is sufficient if each pivot axis of the twin joint can be moved by 90 degrees. When the segments are folded together, a structure that is symmetrical to the central plane of the twin joint is obtained during each movement phase. One of the decisive advantages of the specified twin joint is the possibility of positioning all swivel axes on a straight line running centrally in the rail (in the most general case this can also be a curved line determined by the course of the rail).
Sowohl zur Führung der Segmente als auch des Zwillingsgelenkes wird vorgeschlagen, an der Stirnseite der Schwenkachsen Laufrollen anzuordnen, wobei die Laufrollen der einen Seite in derselben Schiene geführt sind.Both for guiding the segments and the twin joint, it is proposed to arrange rollers on the end of the swivel axes, the rollers on one side being guided in the same rail.
Ein besonders günstiger Antrieb des Tores wird beispielhaft angegeben:
Hierzu wird auf der Achse einer Laufrolle eine Zahnschwinge befestigt, die an ihrem gegenüberliegenden Ende mit einer Führungsrolle versehen ist. Letztere wird in einer nicht der Führung der Laufrolle dienenden Schiene bewegt und dient dazu, die Zahnschwinge zu verschwenken. Deren Aufgabe liegt in Eingriff und Kopplung einer in geringem Abstand angeordneten und angetriebenen Kette. Solange die entsprechenden Segmente zu bewegen sind, findet sich die Zahnschwinge im Eingriff, beim Zusammenfalten endet der Eingriff durch Zurückbewegen der Zahnschwinge und Freigabe der Kette. In der konkreten Realisierung wird die zugehörige Führungsrolle entsprechend bewegt, d.h. sie steht mit der Schiene solange im Eingriff, bis das zugehörige Segment zusammengefaltet wird. Entsprechende Entkupplungshebel nehmen die Führungsrolle auf und bewegen sie von der Kette weg, so daß der Eingriff endet. Gleichzeitig wird der nächst darunter befindliche Entkupplungshebel aktiviert, der der Aufnahme der nächsten Führungsrolle dient. Gemeinsame Aufgabe von Führungsrolle und Entkupplungshebel ist, den Eingriff in die angetriebene Kette im geeigneten Zeitpunkt zu beenden.A particularly favorable drive for the door is given as an example:
For this purpose, a toothed rocker is attached to the axis of a roller, which is provided with a guide roller at its opposite end. The latter is moved in a rail which does not serve to guide the roller and serves to pivot the toothed rocker arm. Their task lies in the engagement and coupling of a chain arranged and driven at a short distance. As long as the corresponding segments are to be moved, the toothed rocker is in engagement, when folding the engagement ends by moving the Toothed rocker and release of the chain. In the specific implementation, the associated guide roller is moved accordingly, ie it is in engagement with the rail until the associated segment is folded up. Appropriate decoupling levers take up the guide roller and move it away from the chain, so that the engagement ends. At the same time, the next uncoupling lever is activated, which is used to hold the next guide roller. The common task of the guide roller and the disengagement lever is to end the engagement in the driven chain at the appropriate time.
Aus Sicherheitsgründen empfiehlt sich die Verwendung einer Endloskette, die ihrerseits in einer Laufschiene und um den Umfang des Kettenrades entgleisungssicher eingebettet ist, damit bei einem Kettenbruch ein Abstürzen des Tores vereitelt wird.For safety reasons, the use of an endless chain is recommended, which in turn is embedded in a track and around the circumference of the sprocket so that the door does not crash if the chain breaks.

Das Tor (1) wird in seiner Gesamtheit durch alle übereinander angeordnete Segmente (2) gebildet. Benachbarte Segmente stehen miteinander entweder über ein auf der Innenseite befindliches Scharnier (3) oder alternierend hierzu an der Stirnseite angeordnetes Raumgelenk-Scharnier (4) in Verbindung, die beide ein Zusammenfalten bzw. Aufeinanderlegen der Segmente (2) gestatten. Sinn und Zweck des Raumgelenk-Scharnieres (4) ist einerseits im Bereich der Außenkante der Stirnseite eine Schwenkachse zu schaffen und andererseits jedoch nicht von außen einsehbar zu sein, so daß das Tor (1) eine homogene Außenansicht darbietet.The gate (1) is formed in its entirety by all segments (2) arranged one above the other. Adjacent segments are either with one another on the inside located hinge (3) or alternatingly arranged on the front side space hinge (4) in connection, both of which allow the segments (2) to be folded or placed on top of one another. The purpose of the hinge (4) is to create a swivel axis in the area of the outer edge of the end face and not to be visible from the outside, so that the door (1) offers a homogeneous exterior view.
Jedes zweite, an der Innenseite befindliche Scharnier (3) ist mit einem Schwinghebel verbunden, dessen äußeres Ende in einer Schiene (6) geführt und mit einem Zahnsegment (7) ausgerüstet ist.Every second hinge (3) located on the inside is connected to a rocker arm, the outer end of which is guided in a rail (6) and equipped with a toothed segment (7).
Das Tor (1) ist am Mauerwerk (8) befestigt und die Schiene (6) weist dort Kipphebel (9) auf, mit deren Erreichen die Schwinghebel (5) sich sukzessive und übereinanderliegend nach außen bewegend das zugehörige Segment (2) in die horizontale Position verklappen. Im geöffneten Zustand wird jeder Kipphebel durch einen darüber gleitenden Schwinghebel (5) betätigt und das Segment (2) in die horizontale Position verbracht. Die Bewegung des Schwinghebels (5) nach außen bewirkt weiter, daß das hieran befestigte Zahnsegment (7) mit der die Auf- und Abwärtsbewegung vornehmenden Endloskette in Ausgriff kommt und nicht mehr weitergeführt wird.The gate (1) is attached to the masonry (8) and the rail (6) there has rocker arms (9) with which the rocker arms (5) successively and one above the other move the associated segment (2) horizontally Collapse position. In the open state, each rocker arm is actuated by a rocking lever (5) sliding over it and the segment (2) is brought into the horizontal position. The movement of the rocker arm (5) outwards causes the toothed segment (7) attached to it to come into engagement with the endless chain which makes the upward and downward movement and is no longer continued.
Umgekehrt verlassen beim Schließen des Tores die einzelnen Schwinghebel (5) nacheinander und von unten her beginnend ihre Ruheposition im Bereich des jeweiligen Kipphebels (9), greifen in die Endloskette (10) ein und werden nach unten mitgeführt.Conversely, the individual swing levers (5) leave one after the other when the gate closes and starting from below their rest position in the area of the respective rocker arm (9), engage in the endless chain (10) and are carried downwards.
Die Endloskette (10) wird hierbei in üblicher Weise über einen Antrieb (11) in Bewegung gesetzt.The endless chain (10) is set in motion in the usual way via a drive (11).
Figur 2 zeigt ein Längsschnitt durch ein Tor (1), welches in einem Mauerwerk (8) befestigt ist und dessen oberen vier Segmente (2) gänzlich oder teilweise zur Schließstellung zusammengeklappt sind. Gut zu erkennen ist die Möglichkeit des Zusammenfaltens auf engstem Raum. Die Segmente sind über zwei parallel zueinander verlaufende Schwenkachsen aufweisende Zwillingsgelenke (12) verbunden und gestatten das Verschwenken benachbarter Segmente (2) um maximal 180 Grad. Die Formgebung des Zwillingsgelenkes (12) ist so gewählt, daß eine Außenfläche des Spaltes benachbarte Segmente (2) geschlossen und überdeckt wird. Die gegenüberliegende Flächen desselben Spaltes wird außenflächig mit einem Dichtungsstreifen (13) überbrückt, dessen elastische Eigenschaften das Zusammenfalten der Segmente (2) erlaubt. Zumindest nach außen zu ist die Abdeckung des Spaltes zwischen benachbarten Segmenten (2) von entscheidendem Vorteil, da sie eine angenehme ästethische Oberfläche bildet und gleichzeitig das Eindringen von Feuchtigkeit verhindert.Figure 2 shows a longitudinal section through a gate (1) which is fixed in a masonry (8) and the upper four segments (2) are completely or partially folded to the closed position. The possibility of folding in a confined space is clearly visible. The segments are connected by means of two twin joints (12) which run parallel to one another and allow adjacent segments (2) to be pivoted by a maximum of 180 degrees. The shape of the twin joint (12) is chosen so that an outer surface of the gap adjacent segments (2) is closed and covered. The opposite surfaces of the same gap are bridged on the outside with a sealing strip (13), the elastic properties of which allow the segments (2) to be folded together. Covering the gap between adjacent segments (2) at least to the outside is of decisive advantage since it forms a pleasant aesthetic surface and at the same time prevents the penetration of moisture.
Figur 3 zeigt den in einer speziellen Ausführungsform vorgeschlagenen Antrieb des Segmenttores. Es weist ein Zwillingsgelenk (12) auf, welches mit zwei geführten Laufrollen (14) versehen ist. Auf der unteren Laufrolle (14) ist eine Zahnschwinge (15) befestigt, die an ihrem gegenüberliegenden Ende mit einer Führungsrolle (16) versehen ist. Letztere wird in einer Schiene (17) geführt und über in diese angreifende Entkupplungshebel (18) nach außen bewegt, so daß die Zahnschwinge (15) nach links zu verschwenkt wird. Der Antrieb erfolgt über die endlos umlaufende Kette (10) vermittels der in Eingriff stehenden Zahnschwinge (15). Da im zusammengefaltete Zustand der Segmente (2) deren Position raumfest bleibt, muß der Eingriff in die Kette (10) beendet werden. Die dann von der Zahnschwinge (15) eingenommene Position läßt sich aus der im oberen Bereich wiedergegebenen Zahnschwinge (15) entnehmen. Jeder Entkupplungshebel (18) wird dann zur Aufnahme der Führungsrolle (16) in die Schiene (17) verbracht, wenn der darüber liegende Entkupplungshebel (18) die zugehörige Führungsrolle (16) erfaßt hat.FIG. 3 shows the drive of the segment gate proposed in a special embodiment. It has a twin joint (12) which is provided with two guided rollers (14). A toothed rocker arm (15) is attached to the lower roller (14) and is provided with a guide roller (16) at its opposite end. The latter is guided in a rail (17) and is moved outwards via decoupling levers (18) engaging in it, so that the toothed rocker arm (15) is pivoted to the left. The drive takes place via the endless chain (10) by means of the toothed rocker (15) in engagement. Since in the folded state of the segments (2) their position remains fixed, the engagement in the chain (10) must be ended. The position then assumed by the rocker arm (15) can be seen from the rocker arm (15) shown in the upper area. Each decoupling lever (18) is then placed in the rail (17) to receive the guide roller (16) when the decoupling lever (18) above it has gripped the associated guide roller (16).
Im Ergebnis werden die einzelnen Entkupplungshebel von oben nach unten zu sukzessive in die Schiene (17) verbracht und nehmen jeweils eine Führungsrolle (16) auf. Deren Abstand ist gleich dem Abstand benachbarter Führungsrollen (16) im zusammengeklappten Zustand des Tores.As a result, the individual decoupling levers are successively brought into the rail (17) from top to bottom and each take up a guide roller (16). Their distance is equal to the distance between adjacent guide rollers (16) when the door is folded.
Aufgrund der Tatsache, daß jedes Zwillingsgelenk (12) über die zugehörige Zahnschwinge (15) mit der Kette (10) in Verbindung steht und bewegt wird, tritt eine kräftemäßige Verteilung auf die einzelnen Segmente und eine punktuelle Entlastung ein.Due to the fact that each twin joint (12) is connected to the chain (10) via the associated toothed rocker arm (15) and is moved, there is a force distribution to the individual segments and a selective relief.
Claims (9)
