Definitions
- the present invention relates to a rail element for a door drive, in particular a garage door, with a rail and a drive means, in particular a chain or a toothed belt, wherein at a deflection end of the rail element, a guide roller and at a drive end of the rail element, a drive wheel are provided, via which the Drive means is guided circumferentially, so that the drive means extends in two opposing strands within the rail.
- the rail of the rail element is arranged for this purpose between the deflecting end of the rail element and the drive end of the rail element.
- the present invention relates to a door drive with such a rail element.
- Such rail elements are usually used to open a gate, in particular a garage door, through the door drive and close.
- a carriage is provided, which is displaceable in the usually C-shaped rail and connected to one of the two parallel strands of the drive means is such that the carriage is moved during a movement of the drive means along the rail.
- a driver On the carriage is usually further arranged a driver, which is in communication with the gate and so the door opens and closes.
- a drive motor is connected, which moves the drive wheel, wherein by a rotation of the drive wheel, the drive means in the rail is moved circumferentially, so that the two parallel strands of the drive means in the rail move in opposite directions.
- Such a rail element for a door drive, in which a toothed belt is used as drive means, is for example out DE 780 17 016 U1 known.
- the two strands of the drive means run in the rail parallel to an imaginary connecting line between the axis of rotation of drive wheel and pulley, with a distance to the imaginary connecting line, which corresponds to the deflection of the drive means to drive wheel or pulley.
- Drive means such.
- the width of the rail is determined by the minimum radius of the drive means, since the distance between the two strands within the rail corresponds to the diameter of the drive wheel or pulley.
- the drive wheel regardless of the minimum radius of the drive means can not be made arbitrarily small in order to ensure a reliable power transmission from the drive wheel to the drive means.
- Object of the present invention is to enable a narrower profile of the rail.
- a rail element for a door drive, in particular a garage door, in this case has a rail and a drive means, in particular a chain or a toothed belt, wherein at a deflection end of the rail element, a guide roller and at a drive end of the rail element, a drive wheel are provided, via which the Drive means is guided circumferentially, so that the drive means extends in two opposing strands within the rail.
- such a rail element is now provided that one of the strands of the drive means is guided by the drive wheel via a deflecting element in the rail, so that the distance between the two opposing strands of the drive means within the rail is smaller than the diameter of the drive wheel.
- the rear side of the drive means touches the deflecting element in a region whose distance from the imaginary connecting line between the axis of rotation of the drive wheel and deflection roller is smaller than the radius of rotation of the rear side of the deflecting means about the drive wheel.
- a very narrow rail can be used, since the two parallel strands of the drive means extending within the rail no longer spaced apart as in the prior art must have, which is determined by the radius of rotation about the drive wheel, but are guided by the deflection closer to each other.
- the narrow rail ensures compact drives and packaging for easy transport and trouble-free installation.
- the compact design allows the drive system, consisting of the rail element and the drive motor, to be pre-assembled and used as a component for various door drives.
- the other strand of the drive means without a deflecting element extends directly from the drive wheel into the rail.
- the one strand within the rail extends along a straight line which is a distance from the axis of rotation of the drive wheel, which is less than the radius of rotation of the drive means to the drive wheel, so that between the end of the rail and the drive wheel by the deflection must be deflected while the other strand runs on a straight line which tangentially meets the drive wheel and whose distance from the axis of rotation of the drive wheel thus corresponds exactly to the radius of rotation of the drive means.
- a separating element between the two counter-rotating strands is provided in an area adjoining the deflecting element. Since the two strands are guided closer together in this area by the deflecting element, without the separating element would result here an increased risk of mutual contact, and a resulting entanglement of the two strands of the drive means.
- the separating element which z. B. can be formed by a partition between the load strand and the slack side, the two strands closer to each other, however, can not touch.
- the teeth of a toothed belt used as a drive means interlock with each other. It is sufficient if the separating element is provided only in a certain range following the deflecting element, since within the rail, the two strands are parallel and thus less likely to catch.
- the drive wheel, the deflecting element and optionally the separating element are arranged in a common housing.
- the housing advantageously also has a receptacle for receiving a rail end.
- the rail end can be advantageously inserted into the receptacle or attached to the receptacle to easily attach the housing to the rail. This allows the rail element easily mount by connecting the rail with the assembly of drive wheel and deflector and optionally separating element.
- the deflection side is constructed in analogy to the drive side.
- one of the strands of the drive means is guided by the deflection roller over a deflection-side deflection in the rail, so that the distance between the two opposing strands of the drive means within the rail is smaller than the diameter of the guide roller. If the minimum radius of the drive means is greater than half the desired distance of the two strands of the drive means within the rail, such an arrangement is necessary in order not to fall below this minimum radius on the deflection side.
- Deflection pulley and drive wheel can, for example, have the same, given by the minimum radius of the drive means radius. But it is also possible that pulley and drive wheel have different Radii. By the deflection then the two strands are tapered on the drive side and on the deflection side to the same distance from each other.
- the other strand of the drive means without a deflecting element is guided directly from the deflection roller in the rail on the deflection side.
- the drive side there is again a considerable reduction in the friction losses, since only one strand is deflected while the other strand runs directly onto the deflection roller.
- a deflection-side separating element between the two opposing strands is further provided in an adjoining the deflection-side deflection element area. This, in turn, also prevents the two strands from becoming caught in the area in which they are guided closer to one another.
- the deflection roller, the deflection-side deflecting element and optionally the deflection-side separating element are arranged in a common housing. Again, this results in a simple construction and easy installation, and here again advantageously a receptacle for the rail is provided.
- the deflection roller for tensioning the drive means is adjustable, in particular via an eccentric. This makes it possible, after assembly by adjusting the pulley to increase the distance between the drive wheel and pulley and so to tension the drive means.
- guide pulley and deflection-side deflection element thereby form a structural unit which is displaceable relative to the housing to which the rail is fastened.
- the rail element according to the invention has drive-side connecting elements for connection to a drive motor and deflection-side fastening elements for mounting the rail element.
- Drive side so the drive motor z. B. are attached to the housing, in which the drive wheel is located, which is then driven by the drive motor.
- the rail of the rail element according to the invention has a plurality of rail segments which can be continuously mounted in the longitudinal direction.
- the pack size of the rail element can be reduced, wherein the individual rail segments are then connected to each other in place by connecting elements and form a continuous rail.
- the present invention comprises a preassembled assembly of a rail element as described above and a drive motor.
- a drive system can be used by the compact design of the rail element as a component for various door drives.
- the present invention further comprises a door drive with a rail element, as described above, in particular a garage door drive.
- a door drive has the same advantages as have already been described with respect to the rail element.
- FIGS. 1 and 2 the rail element according to the invention is shown in a transport position in which the individual rail segments of the rail 1 are not yet connected to each other, so that the drive side 4 connected to a first rail segment, a middle rail segment and the deflecting side 3 connected to a third rail segment are folded next to each other ,
- the rail segments of the rail 1 of the invention Rail element thereby have a C-shaped profile.
- On the drive side 4 is then fastened via connecting elements 34, a drive unit of a motor 10 and a transmission 11 from below, as shown in FIG FIG. 3 is shown.
- the rail element according to the invention is usually horizontal way above the gate on the ceiling z.
- the rail 1 then usually runs parallel to the horizontal guide rails, in which the door leaf or the door leaf elements are guided.
- the drive wheel is rotated by a drive motor 10, whereby the drive means 2 carries out a circumferential movement within the rail, so that the two strands of the drive means 2 running parallel within the rail 1 are moved in opposite directions. With one of the two strands while a carriage is connected, which is thereby moved in the rail. The carriage is in turn connected via a driver with the door leaf, so that the door is opened by a movement of the drive wheel in one direction and the door is closed by a movement in the other direction.
- drive side 4 is now based on the FIGS. 4 to 7 shown in more detail.
- the corresponding executed deflection 3 is then based on the FIGS. 8 to 13 described in more detail.
- drive side and deflection side are designed so that the distance between the two strands within the rail can be smaller than the diameter of the drive wheel or the deflection roller, which are determined by the minimum bending radius of the toothed belt used as a drive means, which allows the narrow profile of the rail 1.
- FIG. 4 now shows the drive side of the embodiment of the rail element according to the invention in an exploded view obliquely from below, FIG. 5 from diagonally above.
- the drive means 2 in the form of a toothed belt runs around the drive wheel 6, which is rotatably mounted in a housing of a lower shell 12 and an upper shell 13.
- the diameter of the drive wheel 6 is greater than the distance between the two opposing strands of the drive means within the rail 1.
- a deflecting element 7 is provided on one side of the drive wheel 6, through which the course of the drive means tapers.
- the region of the deflecting element which is in contact with the rear side of the drive means, is at a distance from the imaginary connecting line between the axis of rotation of the drive wheel and the axis of rotation of the deflecting roller, which is smaller than the rotational radius of the rear side of the drive means about the drive wheel.
- a deflecting element is provided only for one of the two strands, while the other strand runs directly on the drive wheel 6 and is not influenced by a deflecting element in its path in the region of the drive wheel.
- the deflecting element 7 has a plurality of sliding pins on which the rear side of the drive means slides and which deflect the drive means in such a way that the two strands are guided toward one another.
- a roller or a roller arrangement may be used, on which the rear side of the drive means runs.
- separating elements 8 are provided, which separate the two strands of the drive means from each other in the region of the deflecting element and in the adjoining region.
- a first portion of the separating element 8 is arranged on the upper shell 13, and a second region on the lower shell 12. In this way, load strand and slack side are separated, so that the teeth of the toothed belt can not catch each other.
- the drive end 3 of the rail element comprises a housing which is constructed from a lower shell 12 and an upper shell 13, which are connected to one another via connecting bolts 14 and to the drive unit comprising drive motor 10 and transmission 11.
- both the drive wheel 6 are mounted, as well as the deflecting element 7 and the separating elements 8 integrated.
- the housing has a receptacle 15, in which the profile of the rail 1 is inserted.
- FIG. 6 is again easy to see how the toothed belt 2 rotates with a strand directly on the drive wheel 6, while the other drive train is deflected by the deflecting element 7 in the direction of the first strand, so that the resulting distance between the two strands is smaller than that Diameter of the drive wheel 6. Furthermore, the separator 8 between the two strands can be seen, which prevents a hooking of the two strands with each other in the deflection.
- FIG. 7 are now the lower shell 12 and the upper shell 13 of the housing screwed together and the drive unit of drive motor 10 and gear 11 connected to the rail element.
- the rail 1 was inserted into the receptacle 15 and fastened there.
- the mounted rail element can be installed as a unit with the drive unit in different door drives.
- FIGS. 8 and 9 now show the deflecting 3 of the rail element in a partial exploded view in which a cover member 23 has been removed from the deflection.
- the drive means runs around the deflection roller 5, wherein in turn on one side a deflecting element 17 is provided in the form of two sliding pins, on which runs the back of the toothed belt and is deflected so.
- the diameter of the deflection roller 5 is greater than the distance between the two strands of the drive means 2 within the rail.
- one strand without deflection elements runs directly on the deflection roller, while the other strand is deflected inwards. Again, this results in only low friction losses and yet the narrow design of the rail 1 according to the invention.
- a separating element 18 is also provided on the deflection side 3 between the two strands, so that the teeth of the toothed belt 2 can not catch each other when they are guided closer to each other in the deflection.
- a housing 22 which has a receptacle 30 on one side, in which the rail 1 can be inserted. Opposite, the housing has a fastening element 31, with which it can be connected via an axis with a wall mount 25. The wall bracket 25 is then mounted on the fall side above the gate.
- the deflection roller 5 In order to tension the drive means 2 after assembly of the rail element, the deflection roller 5 is displaceable within the housing 22.

- FIG. 11 show the Assembly 19, however, in its mounted position, in which the drive means, although applied to the deflection roller, but is still free of stress.
- the assembly with the guide roller 5 runs by means of a screw 27 in a slot 28 in the housing 22, which extends parallel to the longitudinal direction of the rail 1.
- an eccentric 26 is rotatably mounted in the housing 22, which can move the assembly 19 with the guide roller in the longitudinal direction, if he, as in FIG. 13 is shown, rotated.
- an Allen key 29 is required in the embodiment, by means of which the eccentric is rotated.

Abstract
Description
Die vorliegende Erfindung betrifft ein Schienenelement für einen Torantrieb, insbesondere eines Garagentores, mit einer Schiene und einem Antriebsmittel, insbesondere einer Kette oder einem Zahnriemen, wobei an einem Umlenkende des Schienenelements eine Umlenkrolle und an einem Antriebsende des Schienenelements ein Antriebsrad vorgesehen sind, über welche das Antriebsmittel umlaufend geführt ist, so dass das Antriebsmittel in zwei gegenläufigen Strängen innerhalb der Schiene verläuft. Die Schiene des Schienenelements ist hierfür zwischen dem Umlenkende des Schienenelements und dem Antriebsende des Schienenelements angeordnet.The present invention relates to a rail element for a door drive, in particular a garage door, with a rail and a drive means, in particular a chain or a toothed belt, wherein at a deflection end of the rail element, a guide roller and at a drive end of the rail element, a drive wheel are provided, via which the Drive means is guided circumferentially, so that the drive means extends in two opposing strands within the rail. The rail of the rail element is arranged for this purpose between the deflecting end of the rail element and the drive end of the rail element.
Weiterhin betrifft die vorliegende Erfindung einen Torantrieb mit einem solchen Schienenelement.Furthermore, the present invention relates to a door drive with such a rail element.
Solche Schienenelemente werden üblicherweise dazu eingesetzt, ein Tor, insbesondere ein Garagentor, durch den Torantrieb zu öffnen und zu schließen. Hierfür ist ein Schlitten vorgesehen, welcher in der üblicherweise C-förmigen Schiene verschiebbar ist und mit einem der beiden parallelen Stränge des Antriebsmittels verbunden ist, so dass der Schlitten bei einer Bewegung des Antriebsmittels entlang der Schiene bewegt wird. An dem Schlitten ist üblicherweise weiterhin ein Mitnehmer angeordnet, welcher mit dem Tor in Verbindung steht und so das Tor öffnet und schließt.Such rail elements are usually used to open a gate, in particular a garage door, through the door drive and close. For this purpose, a carriage is provided, which is displaceable in the usually C-shaped rail and connected to one of the two parallel strands of the drive means is such that the carriage is moved during a movement of the drive means along the rail. On the carriage is usually further arranged a driver, which is in communication with the gate and so the door opens and closes.
Weiterhin ist mit dem Antriebsrad des Schienenelementes üblicherweise ein Antriebsmotor verbunden, welcher das Antriebsrad bewegt, wobei durch eine Drehung des Antriebsrades das Antriebsmittel in der Schiene umlaufend bewegt wird, so dass die beiden parallelen Stränge des Antriebsmittels in der Schiene sich in gegenläufige Richtungen bewegen.Furthermore, with the drive wheel of the rail element usually a drive motor is connected, which moves the drive wheel, wherein by a rotation of the drive wheel, the drive means in the rail is moved circumferentially, so that the two parallel strands of the drive means in the rail move in opposite directions.
Ein solches Schienenelement für einen Torantrieb, bei welchem als Antriebsmittel ein Zahnriemen eingesetzt wird, ist beispielsweise aus
Aufgabe der vorliegenden Erfindung ist es, ein schmaleres Profil der Schiene zu ermöglichen.Object of the present invention is to enable a narrower profile of the rail.
Erfindungsgemäß wird diese Aufgabe von einem Schienenelement gemäß Anspruch 1 gelöst. Ein solches Schienenelement für einen Torantrieb, insbesondere eines Garagentors, weist dabei eine Schiene und ein Antriebsmittel, insbesondere eine Kette oder einen Zahnriemen, auf, wobei an einem Umlenkende des Schienenelements eine Umlenkrolle und an einem Antriebsende des Schienenelements ein Antriebsrad vorgesehen sind, über welche das Antriebsmittel umlaufend geführt ist, so dass das Antriebsmittel in zwei gegenläufigen Strängen innerhalb der Schiene verläuft. Erfindungsgemäß ist bei einem solchen Schienenelement nun vorgesehen, dass einer der Stränge des Antriebsmittels vom Antriebsrad über ein Umlenkelement in die Schiene geführt wird, so dass der Abstand der beiden gegenläufigen Stränge des Antriebsmittels innerhalb der Schiene kleiner ist als der Durchmesser des Antriebsrads. Die Rückseite des Antriebsmittels berührt dabei das Umlenkelement in einem Bereich, dessen Abstand von der gedachten Verbindungslinie zwischen den Drehachse von Antriebsrad und Umlenkrolle kleiner ist als der Umlaufradius der Rückseite des Umlenkmittels um das Antriebsrad.According to the invention, this object is achieved by a rail element according to
Hierdurch kann trotz eines großen Mindestradius des Antriebsmittels bzw. trotz eines großen Antriebsrades zur sicheren Übertragung der Antriebskraft auf das Antriebsmittel eine sehr schmale Schiene verwendet werden, da die beiden parallel innerhalb der Schiene verlaufenden Stränge des Antriebsmittels nicht mehr wie im Stand der Technik einen Abstand voneinander aufweisen müssen, welcher durch den Umlaufradius um das Antriebsrad bestimmt ist, sondern durch das Umlenkelement näher aneinander geführt werden. Hierdurch kann gleichzeitig ein großer Umlaufradius und dennoch eine sehr schmale Schiene verwirklicht werden. Die schmale Schiene sorgt dabei für kompakte Antriebe und Verpackungen und damit einen leichten Transport und eine problemlose Montage. Zudem lässt sich durch die kompakte Bauform das Antriebssystem, bestehend aus dem Schienenelement und dem Antriebsmotor, vormontieren und als Komponente für diverse Torantriebe nutzen.In this way, despite a large minimum radius of the drive means or despite a large drive wheel for safe transmission of the driving force to the drive means a very narrow rail can be used, since the two parallel strands of the drive means extending within the rail no longer spaced apart as in the prior art must have, which is determined by the radius of rotation about the drive wheel, but are guided by the deflection closer to each other. As a result, at the same time a large radius of rotation and yet a very narrow rail can be realized. The narrow rail ensures compact drives and packaging for easy transport and trouble-free installation. In addition, the compact design allows the drive system, consisting of the rail element and the drive motor, to be pre-assembled and used as a component for various door drives.
In weiterhin vorteilhafter Weise ist vorgesehen, dass der andere Strang des Antriebsmittels ohne ein Umlenkelement direkt vom Antriebsrad in die Schiene verläuft. Bei dieser Anordnung verläuft der eine Strang innerhalb der Schiene entlang einer Geraden, welche einen Abstand von der Drehachse des Antriebsrades aufweist, welche geringer ist als der Umlaufradius des Antriebsmittels um das Antriebsrad, so dass er zwischen dem Ende der Schiene und dem Antriebsrad durch das Umlenkelement umgelenkt werden muss, während der andere Strang auf einer Geraden verläuft, welche tangential auf das Antriebsrad trifft und deren Abstand von der Drehachse des Antriebsrades damit genau dem Umlaufradius des Antriebsmittels entspricht. Dadurch, dass nur einer der Stränge über ein Umlenkelement näher an den anderen Strang herangeführt wird, während der andere Strang gerade auf das Antriebsrad zuläuft, lassen sich die Reibungsverluste bei der erfindungsgemäßen Anordnung minimieren. Durch diese asymmetrische Ausführung der erfindungsgemäßen Antriebsmittelführung können erfindungsgemäß die niedrigen Reibungsverluste der aus dem Stand der Technik bekannten Antriebe mit einer erheblich schmäleren Schiene kombiniert werden. Dabei wird durch die asymmetrische Ausführung nur ein Umlenkpunkt benötigt, welcher so ausgelegt werden kann, dass sich keine nennenswerte Erhöhung der Verluste gegenüber dem Stand der Technik ergibt.In a further advantageous manner, it is provided that the other strand of the drive means without a deflecting element extends directly from the drive wheel into the rail. In this arrangement, the one strand within the rail extends along a straight line which is a distance from the axis of rotation of the drive wheel, which is less than the radius of rotation of the drive means to the drive wheel, so that between the end of the rail and the drive wheel by the deflection must be deflected while the other strand runs on a straight line which tangentially meets the drive wheel and whose distance from the axis of rotation of the drive wheel thus corresponds exactly to the radius of rotation of the drive means. Characterized in that only one of the strands is brought closer to the other strand via a deflecting element, while the other strand just reaches the drive wheel, the friction losses can be minimized in the inventive arrangement. As a result of this asymmetric design of the drive means guide according to the invention, the low friction losses of the drives known from the prior art can be combined with a considerably narrower rail according to the invention. In this case, only one deflection point is required by the asymmetrical design, which can be designed so that there is no appreciable increase in losses compared to the prior art.
In weiterhin vorteilhafter Weise ist in einem an das Umlenkelement anschließenden Bereich ein Trennelement zwischen den beiden gegenläufigen Strängen vorgesehen. Da die beiden Stränge in diesem Bereich durch das Umlenkelement näher aneinander geführt werden, würde sich hier ohne das Trennelement eine erhöhte Gefahr einer gegenseitigen Berührung, und eines daraus resultierendes Verhakens der beiden Stränge des Antriebsmittels ergeben. Durch das Trennelement, was z. B. von einer Trennwand zwischen Lasttrum und Leertrum ausgebildet werden kann, können sich die beiden näher zueinander geführten Stränge dagegen nicht berühren. Hierdurch wird auch sicher vermieden, dass sich z.B. die Zähne eines als Antriebsmittel verwendeten Zahnriemens miteinander verhaken. Dabei ist es ausreichend, wenn das Trennelement nur in einem gewissen Bereich im Anschluß an das Umlenkelement vorgesehen ist, da innerhalb der Schiene die beiden Stränge parallel verlaufen und sich damit weniger leicht verhaken.In a further advantageous manner, a separating element between the two counter-rotating strands is provided in an area adjoining the deflecting element. Since the two strands are guided closer together in this area by the deflecting element, without the separating element would result here an increased risk of mutual contact, and a resulting entanglement of the two strands of the drive means. By the separating element, which z. B. can be formed by a partition between the load strand and the slack side, the two strands closer to each other, however, can not touch. As a result, it is also safely avoided that, for example, the teeth of a toothed belt used as a drive means interlock with each other. It is sufficient if the separating element is provided only in a certain range following the deflecting element, since within the rail, the two strands are parallel and thus less likely to catch.
In weiterhin vorteilhafter Weise ist bei dem erfindungsgemäßen Schienenelement das Antriebsrad, das Umlenkelement und gegebenenfalls das Trennelement in einem gemeinsamen Gehäuse angeordnet. Hierdurch ergibt sich eine einfache und kompakte Baugruppe aus Antriebsrad und Umlenkelement und gegebenenfalls Trennelement. Das Gehäuse weist vorteilhafterweise weiterhin eine Aufnahme zur Aufnahme eines Schienenendes auf. Zum Beispiel kann das Schienenende vorteilhafterweise in die Aufnahme eingesteckt oder auf die Aufnahme aufgesteckt werden, um das Gehäuse einfach an der Schiene zu befestigen. Hierdurch kann das Schienenelement problemlos durch Verbinden der Schiene mit der Baugruppe aus Antriebsrad und Umlenkelement und gegebenenfalls Trennelement montieren.In a further advantageous manner, in the rail element according to the invention, the drive wheel, the deflecting element and optionally the separating element are arranged in a common housing. This results in a simple and compact assembly of drive wheel and deflector and optionally separator. The housing advantageously also has a receptacle for receiving a rail end. For example, the rail end can be advantageously inserted into the receptacle or attached to the receptacle to easily attach the housing to the rail. This allows the rail element easily mount by connecting the rail with the assembly of drive wheel and deflector and optionally separating element.
In weiterhin vorteilhafter Weise ist bei dem erfindungsgemäßen Schienenelement auch die Umlenkseite in Analogie zu der Antriebsseite aufgebaut. Vorteilhafterweise ist dabei einer der Stränge des Antriebsmittels von der Umlenkrolle über ein umlenkseitiges Umlenkelement in die Schiene geführt, so dass der Abstand der beiden gegenläufigen Stränge des Antriebsmittels innerhalb der Schiene kleiner ist als der Durchmesser der Umlenkrolle. Ist der Mindestradius des Antriebsmittels größer als die Hälfte des gewünschten Abstands der beiden Stränge des Antriebsmittels innerhalb der Schiene, ist eine solche Anordnung notwendig, um auch auf der Umlenkseite diesen Mindestradius nicht zu unterschreiten.In a further advantageous manner in the rail element according to the invention, the deflection side is constructed in analogy to the drive side. Advantageously, while one of the strands of the drive means is guided by the deflection roller over a deflection-side deflection in the rail, so that the distance between the two opposing strands of the drive means within the rail is smaller than the diameter of the guide roller. If the minimum radius of the drive means is greater than half the desired distance of the two strands of the drive means within the rail, such an arrangement is necessary in order not to fall below this minimum radius on the deflection side.
Umlenkrolle und Antriebsrad können dabei z.B. den gleichen, durch den Mindestradius des Antriebsmittels vorgegebenen Radius haben. Ebenso ist es aber möglich, dass Umlenkrolle und Antriebsrad unterschiedliche Radii aufweisen. Durch die Umlenkelemente werden dann die beiden Stränge auf der Antriebsseite und auf der Umlenkseite auf den gleichen Abstand zueinander verjüngt.Deflection pulley and drive wheel can, for example, have the same, given by the minimum radius of the drive means radius. But it is also possible that pulley and drive wheel have different Radii. By the deflection then the two strands are tapered on the drive side and on the deflection side to the same distance from each other.
In vorteilhafter Weise ist auch auf der Umlenkseite der andere Strang des Antriebsmittels ohne ein Umlenkelement direkt von der Umlenkrolle in die Schiene geführt. Hierdurch ergibt sich wie auf der Antriebsseite wiederum eine erhebliche Verringerung der Reibungsverluste, da nur der eine Strang umgelenkt wird, während der andere Strang direkt auf die Umlenkrolle aufläuft.Advantageously, the other strand of the drive means without a deflecting element is guided directly from the deflection roller in the rail on the deflection side. As a result, as on the drive side, there is again a considerable reduction in the friction losses, since only one strand is deflected while the other strand runs directly onto the deflection roller.
Vorteilhafterweise ist weiterhin in einem an das umlenkseitige Umlenkelement anschließenden Bereich ein umlenkseitiges Trennelement zwischen den beiden gegenläufigen Strängen vorgesehen. Auch hierdurch wird wiederum vermieden, dass sich die beiden Stränge in dem Bereich, in welchem sie näher aneinander geführt werden, verhaken.Advantageously, a deflection-side separating element between the two opposing strands is further provided in an adjoining the deflection-side deflection element area. This, in turn, also prevents the two strands from becoming caught in the area in which they are guided closer to one another.
In weiterhin vorteilhafter Weise sind die Umlenkrolle, das umlenkseitige Umlenkelement und gegebenenfalls das umlenkseitige Trennelement in einem gemeinsamen Gehäuse angeordnet. Auch hierdurch ergibt sich wieder eine einfache Konstruktion und eine problemlose Montage, wobei auch hier vorteilhafterweise wieder eine Aufnahme für die Schiene vorgesehen ist.In a further advantageous manner, the deflection roller, the deflection-side deflecting element and optionally the deflection-side separating element are arranged in a common housing. Again, this results in a simple construction and easy installation, and here again advantageously a receptacle for the rail is provided.
In weiterhin vorteilhafter Weise ist erfindungsgemäß die Umlenkrolle zum Spannen des Antriebsmittels verstellbar, insbesondere über einen Exzenter. Hierdurch ist es möglich, nach der Montage durch ein Verstellen der Umlenkrolle den Abstand zwischen Antriebsrad und Umlenkrolle zu erhöhen und so das Antriebsmittel zu spannen.In a further advantageous manner according to the invention, the deflection roller for tensioning the drive means is adjustable, in particular via an eccentric. This makes it possible, after assembly by adjusting the pulley to increase the distance between the drive wheel and pulley and so to tension the drive means.
Vorteilhafterweise bilden dabei Umlenkrolle und umlenkseitiges Umlenkelement eine Baueinheit, welche gegenüber dem Gehäuse, an welchem die Schiene befestigt wird, verschiebbar ist.Advantageously, guide pulley and deflection-side deflection element thereby form a structural unit which is displaceable relative to the housing to which the rail is fastened.
In weiterhin vorteilhafter Weise weist das erfindungsgemäße Schienenelement antriebsseitige Verbindungselemente zur Verbindung mit einem Antriebsmotor und umlenkseitige Befestigungselemente zur Montage des Schienenelementes auf. Antriebsseitig kann so der Antriebsmotor z. B. an dem Gehäuse befestigt werden, in welchem sich das Antriebsrad befindet, welches dann vom Antriebsmotor angetrieben wird. Umlenkseitig wird das Schienenelement z. B. mit dem Gehäuse, in welchem die Umlenkrolle angeordnet ist, an der Wand der Garage sturzseitig befestigt.In a further advantageous manner, the rail element according to the invention has drive-side connecting elements for connection to a drive motor and deflection-side fastening elements for mounting the rail element. Drive side so the drive motor z. B. are attached to the housing, in which the drive wheel is located, which is then driven by the drive motor. Deflection, the rail element z. B. with the housing in which the guide roller is arranged on the wall of the garage mounted on the fall side.
In weiterhin vorteilhafter Weise weist die Schiene des erfindungsgemäßen Schienenelements mehrere, in Längsrichtung fortlaufend montierbare Schienensegmente auf. Hierdurch lässt sich das Packmaß des Schienenelementes reduzieren, wobei die einzelnen Schienensegmente dann an Ort und Stelle durch Verbindungselemente miteinander verbunden werden und eine durchgehende Schiene bilden.In a further advantageous manner, the rail of the rail element according to the invention has a plurality of rail segments which can be continuously mounted in the longitudinal direction. As a result, the pack size of the rail element can be reduced, wherein the individual rail segments are then connected to each other in place by connecting elements and form a continuous rail.
In weiterhin vorteilhafter Weise umfasst die vorliegende Erfindung eine vormontierte Baugruppe aus einem Schienenelement, wie es oben beschrieben wurde und einem Antriebsmotor. Ein solches Antriebssystem lässt sich durch die kompakte Bauform des Schienenelementes als Komponente für diverse Torantriebe nutzen.In a further advantageous manner, the present invention comprises a preassembled assembly of a rail element as described above and a drive motor. Such a drive system can be used by the compact design of the rail element as a component for various door drives.
In weiterhin vorteilhafter Weise umfasst die vorliegende Erfindung weiterhin einen Torantrieb mit einem Schienenelement, wie es oben beschrieben wurde, insbesondere einem Garagentorantrieb. Ein solcher Torantrieb hat die gleichen Vorteile, wie sie bereits bezüglich des Schienenelementes beschrieben wurden.In a further advantageous manner, the present invention further comprises a door drive with a rail element, as described above, in particular a garage door drive. Such a door drive has the same advantages as have already been described with respect to the rail element.

An der Antriebsseite 4 ist dabei ein Antriebsrad vorgesehen, und an der Umlenkseite 3 eine Umlenkrolle, über welche das Antriebsmittel 2, im Ausführungsbeispiel ein Zahnriemen, umlaufend geführt ist. Das erfindungsgemäße Schienenelement wird dabei üblicher Weise horizontal oberhalb des Tores an der Decke z. B. einer Garage angeordnet, wobei die Umlenkseite 3 im Bereich des Torsturzes befestigt wird. Die Schiene 1 verläuft dann üblicherweise parallel zu den horizontalen Führungsschienen, in welchen das Torblatt bzw. die Torblattelemente geführt sind.On the
Das Antriebsrad wird dabei von einem Antriebsmotor 10 gedreht, wodurch das Antriebsmittel 2 innerhalb der Schiene eine umlaufende Bewegung vollführt, so dass die beiden innerhalb der Schiene 1 parallel verlaufenden Stränge des Antriebsmittels 2 gegenläufig bewegt werden. Mit einem der beiden Stränge ist dabei ein Schlitten verbunden, welcher hierdurch in der Schiene bewegt wird. Der Schlitten ist wiederum über einen Mitnehmer mit dem Torblatt verbunden, so dass durch eine Bewegung des Antriebsrads in die eine Richtung das Tor geöffnet und durch eine Bewegung in die andere Richtung das Tor geschlossen wird.The drive wheel is rotated by a
Die erfindungsgemäße Ausführung der Antriebsseite 4 wird nun anhand von den
Durch diese asymmetrische Anordnung des Antriebsrades 6 gegenüber der Mittellinie der Schiene 1 ergibt sich eine Anordnung, bei welcher einerseits ein geringer Abstand der beiden gegenläufigen Stränge des Antriebsmittels innerhalb der Schiene und damit ein sehr schmales Schienenprofil realisiert werden kann, und andererseits Reibungsverluste minimiert werden können, da nur für einen der beiden Stränge ein Umlenkelement 7 vorgesehen ist. Das Umlenkelement 7 weist dabei in dem Ausführungsbeispiel mehrere Gleitstifte auf, auf welchen die Rückseite des Antriebsmittels entlang gleitet und welche das Antriebsmittel so umlenken, dass die beiden Stränge aufeinander zu geführt werden. Alternativ könnte als Umlenkelement 7 auch eine Rolle oder eine Rollenanordnung verwendet werden, auf welcher die Rückseite des Antriebsmittels läuft.This asymmetrical arrangement of the
Weiterhin sind Trennelemente 8 vorgesehen, welche im Bereich des Umlenkelements sowie im sich daran anschließenden Bereich die beiden Stränge des Antriebsmittels voneinander trennen. Im Ausführungsbeispiel ist dabei ein erster Teilbereich des Trennelementes 8 an der Oberschale 13 angeordnet, sowie ein zweiter Bereich an der Unterschale 12. Hierdurch werden Lasttrum und Leertrum voneinander getrennt, so dass sich die Zähne des Zahnriemens nicht miteinander verhaken können.Furthermore, separating
Das Antriebsende 3 des Schienenelementes umfasst dabei ein Gehäuse, welches aus einer Unterschale 12 und einer Oberschale 13 aufgebaut ist, welche über Verbindungsschrauben 14 miteinander sowie mit der Antriebseinheit aus Antriebsmotor 10 und Getriebe 11 verbunden werden. In dem Gehäuse sind dabei sowohl das Antriebsrad 6 gelagert, als auch das Umlenkelement 7 und die Trennelemente 8 integriert.
