Definitions
- the invention relates to a power transmission element for a drive on a sliding gate in the form of a rack for the engagement of a pinion of the drive motor, according to the features of the preamble of claim 1.
- toothed racks made of steel have previously been used, in which lubrication had to be provided for corrosion protection reasons, so that constant maintenance was required.
- a sliding device for a gate which has a motor which drives a pinion which engages in a toothed rack which is fastened to a gate by means of a sliding profile.
- the invention has for its object to design a power transmission element of the type described above so that it is practically maintenance-free.
- This arrangement not only has the advantage that by using a corrosion-resistant material for the tooth element maintenance is reduced, but also the advantage that a configuration can be created in which the tooth element is detachably connected to the carrier element, so that the tooth element can be replaced after a corresponding operating time. It is particularly expedient if the tooth element is divided into several sub-elements. This offers the possibility of providing a basic profile for the carrier element, for example an extruded or bent profile of a commercial type and length, so that this profile only needs to be cut to length for the respective application. By subdividing the tooth element into sub-elements of, for example, 15 cm, it is then possible to also produce force transmission elements of any length using standard elements within the grid predetermined by the length of the sub-elements.
- the tooth element consists of an impact-resistant and abrasion-resistant plastic. This provides not only the required corrosion resistance, but also the required freedom from maintenance, since such plastic toothed elements can engage either with a corresponding plastic or metal pinion, without the need for lubrication. Another advantage is that the manufacture is simplified if injection-moldable and / or pourable plastics are used, since this enables the cost-effective production of partial elements in large quantities. Examples of suitable plastics here are polyacetals (POM), polyamides, polyurethane (PUR), polytetrafluoroethylene (PTFE) or plastics with comparable technical properties.
- POM polyacetals
- PUR polyurethane
- PTFE polytetrafluoroethylene
- the tooth element has a base to which the teeth are connected and that the base the teeth laterally limiting and firmly connected to these webs.
- the lateral webs connected to the teeth result in a high level of structural stability, since the force is transmitted not only via the tooth base but also via the webs connected laterally to the teeth. This makes it possible to use smaller toothed elements with the same load capacity in terms of dimensions.
- the base of the tooth element is provided on its side facing away from the teeth with a back groove running in the longitudinal direction. This results not only in a reduction in material consumption without impairing the strength, but also in the possibility of creating space for the arrangement of fastening means on the carrier element through this groove.
- the carrier element is designed as a C-profile and that the tooth element is fastened in the C-profile.
- the C-profile of the carrier element is provided at both ends with stop pieces for the tooth element and that at least one stop piece is designed to be braced in the longitudinal direction.
- This configuration has the advantage in particular when using a plurality of sub-elements that the tooth element or the sub-elements only need to be inserted loosely into the C-profile and are then firmly clamped in the longitudinal direction via the stop pieces in the C-profile.
- This also has the advantage that if the tooth element or a partial element is damaged, the partial elements can be pulled out in a simple manner by loosening a stop piece and replaced with new ones.
- the C-profile is provided on its back side with through holes for screw bolts and that the width of the back groove of the tooth element corresponds to the width across flats of the head of the screw bolts to be used.
- the bolts are pushed through from the open side of the C-profile and then the sub-elements are inserted, the back groove encompassing the head of the bolt used in a form-fitting manner.
- This not only reduces the overall height of the C-profile to be used, but also creates an assembly aid, since the tooth element used also serves as a torque holder for the screw bolt, so that the required assembly nuts can be easily screwed on here.
- the carrier element is provided on its side facing away from the tooth element with a hollow rail, on which electrical control lines are arranged and in which a sliding part is guided, which projects outwards through a longitudinal slot with a shoulder, the Approach can be attached to a fixed gate part and serves as a connection element for the control lines between the movable and the fixed gate part.
- the carrier element is designed so that on the one hand the tooth element, but on the other hand also the control lines for such switching devices are arranged in one component, there is the possibility of a workshop pre-assembly, so that only the support element is screwed on site and the necessary Connections must be made. This also allows repairs to be carried out very quickly by replacing the complete assembly. Since the door part moves together with the support element, while the sliding part is fixed with its attachment serving as a connecting element, a possibility for a length compensation possibility corresponding to the length of movement of the door part must be given for the control lines accommodated in the hollow rail. This can either be caused by the control line being helically wound during manufacture, so that the control line can be elastically pulled apart in the manner of a coil spring and the required change in length between the movable gate part and the fixed extension part is ensured.
- guide means for the in the hollow rail Control lines are arranged.
- Such guide means can be formed, for example, by so-called cable drag chains, which are guided in the hollow profile.
- the hollow rail is designed to be longitudinally divisible and part serves as a cover. This arrangement offers the possibility that there is free access to the control lines or the guide means for the control lines in the hollow rail even without having to dismantle the entire power transmission element, so that faults can be easily eliminated on site.
- a sliding gate essentially consists of a gate element 1, which is guided in a sliding bearing arrangement (not shown here) and which is connected to a force transmission element 2.
- the power transmission element 2 is designed as a rack and is connected to the pinion 3 of a drive motor 4.
- a safety device for example in the form of a contact rail, by means of which it must be ensured that the drive motor is switched off immediately when the sliding gate closes as soon as the gate hits an obstacle.
- the gate element 1 bears against a corresponding fixed pillar 6.
- the cross section acc. Fig. 2 shows a preferred embodiment for the power transmission element.
- the force transmission element 2 consists of a carrier element 7 in the form of a C-profile made of metal, preferably a stainless steel, which is firmly connected to the gate element 1 via screw bolts 8 and a shoulder 9.
- a tooth element 10 is inserted into the carrier element 7, which is designed as a C-profile.
- the tooth element 10 has a base 11 to which the teeth 12 are connected.
- the teeth 12 laterally bounding webs 13 are connected, which are also integral with the end faces of the teeth 12, so that, as the perspective view in Fig. 4 shows, the base 11 with the side webs 13 and Teeth 12 form a box-like profile.
- the teeth 12 are thus not only firmly connected to the base 11 with their base but also with their end faces, so that there is a high level of structural strength.
- a back groove 14 (FIG. 4) which is formed by two longitudinal webs 15 in the illustrated embodiment.
- the width of the back groove 14 is dimensioned such that it corresponds to the width across flats of the screw head 16 of the screw bolt 8.
- the power transmission element is now constructed so that first the necessary through holes for the bolts 8 are drilled at the desired intervals, then the bolts 8 are inserted and then the tooth element 10 is inserted.
- the tooth element 10 can be formed in one piece and inserted over the full length of the C-profile 7. However, it is cheaper to divide the tooth element into individual sub-elements that are inserted one after the other into the C-profile.
- the inserted tooth element 10 then secures, as shown in FIG. 2, the screw head 16 of the screw bolt 8 both against falling out and against rotation, so that the fastening nuts shown can then be screwed on and tightened without auxiliary tools.
- the C-profile 7 of the support element is provided at both ends with stop pieces 17 and 18 which are screwed into the profile and are firmly connected to the C-profile 7 via transverse screws 19.
- the stop piece 17 is inserted and fastened first.
- the bolts 8 and the sub-elements of the tooth element 10 are inserted into the C-profile in the manner described above.
- a pressing piece 20 is inserted and then the stop piece 18 is connected to the C-profile.
- the stop piece 18 is provided with an axially guided clamping screw 21, by means of which the partial element forming the tooth element in the C-profile can be firmly clamped via the pressing piece 20.
- Fig. 3 also shows that without having to detach the support element from the gate part, simply by loosening the stop piece 18, the tooth element or individual sub-elements can be pulled out of the C-profile at any time and replaced by new ones.
- Fig. 4 shows that the sub-elements for the tooth element are cast or injection molded from a plastic.
- plastics such as polyacetals, polyamides, polytetrafluorethylene or even polyurethanes are particularly suitable, which have the required high strength but also good uniform properties.
- the partial element which is in engagement with the drive pinion 3 when the sliding gate 1 is in the closed position consists of a metallic material.
- the sub-element 22 in question is hatched. Since the drive motor 4 is designed as a worm gear motor and is therefore self-locking, the sliding gate cannot be moved against the motor by hand.
- the arrangement of a metallic sub-element 22 also offers a gate lock for the area of the closed position, since it is only very tight It is difficult to destroy the toothing between the metallic tooth element and the metallic drive pinion even with a large lever tool.
- Fig. 5 shows in a cross section a further embodiment for the power transmission element.
- a hollow rail 23 is molded onto the C-profile 7, which is produced, for example, as an extruded profile.
- the hollow rail 23 is designed to be longitudinally divisible, so that a removable cover part 24 is provided, which offers free access to the interior of the hollow rail.
- the cover part 24 is designed so that a longitudinal slot 25 remains free, through which an extension 26 of a sliding part 27 is passed to the outside.
- the approach 26 here forms a connection element for a control line which is guided in the hollow rail 23, which is connected to the contact rail 5 of the door on the one hand and via the approach 26 connected to a fixed gate part to a control and switching device connected to the drive motor 4 .
- the hollow rail 23 can also have an essentially circular cross section with a longitudinal slot, so that the control line can be inserted directly into the hollow rail 23 as a helically-spring-wound element. In the closed position, the resilient winding is pulled apart, while in the open position, the resilient winding is contracted.
- the C-profile 7 also offers the possibility of providing the pinion 3 of the drive motor 4 with at least one track and / or support rim 29 which bears against an edge 30 of the C-profile.
- the drive motor 4 is mounted on a rocker so that the pinion 3 with its track edge is pressed against the C-profile with a pressure spring.
- a stop on the rocker ensures that a minimum engagement between the pinion and the tooth element is retained.
- a modified counter wheel can also be assigned to the pinion in this modified form, which runs on the upper side of the C-profile if the fastening means for the carrier element are designed accordingly.
- the C-profile is "clamped" between the pinion and counter wheel, so that the motor mounted on the rocker and also connected to the counter wheel is always tracked by the counter wheel when, for example, the sliding gate is at a somewhat higher level due to deposits or ice formation on its running rails running.
- the pinion is always in precisely defined engagement in the tooth element.
- the tooth element is enclosed by the C-profile including the teeth in the illustrated embodiment and thus largely protected.

Description
Die Erfindung betrifft ein Kraftübertragungselement für einen Antrieb an einem Schiebetor in Form einer Zahnstange für den Eingriff eines Ritzels des Antriebsmotors, entsprechend den Merkmalen des Oberbegriffs des Anspruch 1.The invention relates to a power transmission element for a drive on a sliding gate in the form of a rack for the engagement of a pinion of the drive motor, according to the features of the preamble of claim 1.
Bei Kraftübertragungselementen dieser Art wurden bisher Zahnstangen aus Stahl verwendet, bei denen schon aus Korrosionsschutzgünden eine Schmierung vorgesehen werden mußte, so daß eine ständige Wartung erforderlich war.In the case of power transmission elements of this type, toothed racks made of steel have previously been used, in which lubrication had to be provided for corrosion protection reasons, so that constant maintenance was required.
In der prioritätsälteren, nachveröffentlichten EP-A-0 558 973 ist ein Schiebetor beschrieben, das mittels eines ortsfest angeordneten Antriebsmotoraggregates bewegbar ist, welches ein Antriebsritzel aufweist, das in eine Zahnstangenausbildung kämmend eingreift, wobei die Zahnstangenausbildung aus mehreren Zahnstangensegmenten besteht, die als Fertiggußteile hergestellt werden.In the older, post-published EP-A-0 558 973 a sliding gate is described which can be moved by means of a fixedly arranged drive motor unit which has a drive pinion which meshes with a rack design, the rack design consisting of several rack segments which are manufactured as finished castings will.
Aus DE-U-91 00 504 ist eine Verschiebeeinrichtung für ein Tor bekannt, die einen Motor aufweist, der ein Ritzel antreibt, welches in eine Zahnstange greift, die mittels eines Verschiebeprofils an einem Tor befestigt ist.From DE-U-91 00 504 a sliding device for a gate is known which has a motor which drives a pinion which engages in a toothed rack which is fastened to a gate by means of a sliding profile.
Der Erfindung liegt die Aufgabe zugrunde, ein Kraftübertragungselement der vorstehend bezeichneten Art so auszugestalten, daß es praktisch wartungsfrei ist.The invention has for its object to design a power transmission element of the type described above so that it is practically maintenance-free.
Diese Aufgabe wird gemäß der Erfindung mit den Mitteln des kennzeichnenden Teils des Anspruch 1 gelöstThis object is achieved according to the invention with the means of the characterizing part of claim 1
Diese Anordnung hat nicht nur den Vorteil, daß durch die Verwendung eines korrosionsbeständgen Werkstoffs für das Zahnelement die Wartung reduziert wird, sondern auch noch den Vorteil, daß eine Ausgestaltung geschaffen werden kann, bei der das Zahnelement lösbar mit dem Trägerelement verbunden ist, so daß nach entsprechender Betriebsdauer das Zahnelement ausgewechselt werden kann. Besonders zweckmäßig ist es, wenn das Zahnelement in mehrere Teilelemente unterteilt ist. Dies bietet die Möglichkeit, für das Trägerelement ein Grundprofil, beispielsweise ein Strangpreß- oder Abkantprofil handelsüblicher Art und handelsüblicher Länge vorzusehen, so daß für den jeweiligen Einsatzfall dieses Profil nur abgelängt zu werden braucht. Durch die Unterteilung des Zahnelements in Teilelemente von beispielsweise 15 cm besteht dann die Möglichkeit, ebenfalls mit Standardelementen innerhalb des durch die Länge der Teilelemente vorgegebenen Rasters beliebig lange Kraftübertragungselemente herzustellen.This arrangement not only has the advantage that by using a corrosion-resistant material for the tooth element maintenance is reduced, but also the advantage that a configuration can be created in which the tooth element is detachably connected to the carrier element, so that the tooth element can be replaced after a corresponding operating time. It is particularly expedient if the tooth element is divided into several sub-elements. This offers the possibility of providing a basic profile for the carrier element, for example an extruded or bent profile of a commercial type and length, so that this profile only needs to be cut to length for the respective application. By subdividing the tooth element into sub-elements of, for example, 15 cm, it is then possible to also produce force transmission elements of any length using standard elements within the grid predetermined by the length of the sub-elements.
Besesonders vorteilhaft ist es, daß das Zahnelement aus einem schlagzähen und abriebfesten Kunststoff besteht. Hierdurch ist nicht nur die geforderte Korrosionsfestigkeit gegeben, sondern auch die geforderte Wartungsfreiheit, da derartige Kunststoffzahnelemente entweder mit einem entsprechenden Kunststoff- oder Metallritzel in Eingriff stehen können, ohne daß eine Schmierung notwendig ist. Ein weiterer Vorteil besteht darin, daß die Herstellung vereinfacht ist, wenn spritz- und/oder gießbare Kunststoffe verwendet werden, da hierdurch die Möglichkeit gegeben ist, Teilelement in großen Stückzahlen kostengünstig herzustellen. Als Kunststoff kommen hier beispielsweise in Betracht Polyacetale (POM), Polyamide, Polyurethan (PUR), Polytetrafluorethylen (PTFE) oder Kunststoffe mit vergleichbaren technischen Eigenschaften.It is particularly advantageous that the tooth element consists of an impact-resistant and abrasion-resistant plastic. This provides not only the required corrosion resistance, but also the required freedom from maintenance, since such plastic toothed elements can engage either with a corresponding plastic or metal pinion, without the need for lubrication. Another advantage is that the manufacture is simplified if injection-moldable and / or pourable plastics are used, since this enables the cost-effective production of partial elements in large quantities. Examples of suitable plastics here are polyacetals (POM), polyamides, polyurethane (PUR), polytetrafluoroethylene (PTFE) or plastics with comparable technical properties.
Dadurch, daß das Zahnelement eine Basis aufweist, mit der die Zähne verbunden sind, und daß die Basis die Zähne seitlich begrenzende und mit diesen fest verbundene Stege aufweist. Durch die seitlichen, mit den Zähnen verbundenen Stegen ergibt sich eine hohe Gestaltfestigkeit, da die Kraftübertragung nicht nur über den Zahnfuß sondern auch über die seitlich mit den Zähnen verbundenen Stege erfolgt. Hierdurch besteht die Möglichkeit, bei gleicher Belastbarkeit in den Abmessungen kleiner dimensionierte Zahnelemente einsetzen zu können.Characterized in that the tooth element has a base to which the teeth are connected and that the base the teeth laterally limiting and firmly connected to these webs. The lateral webs connected to the teeth result in a high level of structural stability, since the force is transmitted not only via the tooth base but also via the webs connected laterally to the teeth. This makes it possible to use smaller toothed elements with the same load capacity in terms of dimensions.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß die Basis des Zahnelementes auf ihrer den Zähnen abgekehrten Seite mit einer in Längsrichtung verlaufenden Rückennut versehen ist. Hierdurch ergibt sich nicht nur eine Reduzierung des Werkstoffverbrauchs ohne Beeinträchtigung der Festigkeit, sondern auch die Möglichkeit, durch diese Nut Raum für die Anordnung von Befestigungsmitteln an dem Trägerelement zu schaffen. Gemäß der Erfindung ist hierbei vorgesehen, daß das Trägerelement als C-Profil ausgebildet ist und daß das Zahnelement im C-Profil befestigt ist.In a further embodiment of the invention it is provided that the base of the tooth element is provided on its side facing away from the teeth with a back groove running in the longitudinal direction. This results not only in a reduction in material consumption without impairing the strength, but also in the possibility of creating space for the arrangement of fastening means on the carrier element through this groove. According to the invention it is provided here that the carrier element is designed as a C-profile and that the tooth element is fastened in the C-profile.
In einer bevorzugten Ausgestaltung der Erfindung ist ferner vorgesehen, daß das C-Profil des Trägerelementes an seinen beiden Enden mit Anschlagstücken für das Zahnelement versehen ist und daß wenigstens ein Anschlagstück in Längsrichtung verspannbar ausgebildet ist. Diese Ausgestaltung hat insbesondere bei der Verwendung von mehreren Teilelementen den Vorteil, daß das Zahnelement bzw. die Teilelemente nur losein das C-Profil eingeschoben zu werden brauchen und dann in Längsrichtung über die Anschlagstücke im C-Profil fest verspannt werden. Dies hat ferner den Vorteil, daß bei eventuellen Beschädigungen des Zahnelementes bzw. eines Teilelementes durch Lösen eines Anschlagstückes die Teilelemente in einfacher Weise herausgezogen und durch neue ersetzt werden können.In a preferred embodiment of the invention it is further provided that the C-profile of the carrier element is provided at both ends with stop pieces for the tooth element and that at least one stop piece is designed to be braced in the longitudinal direction. This configuration has the advantage in particular when using a plurality of sub-elements that the tooth element or the sub-elements only need to be inserted loosely into the C-profile and are then firmly clamped in the longitudinal direction via the stop pieces in the C-profile. This also has the advantage that if the tooth element or a partial element is damaged, the partial elements can be pulled out in a simple manner by loosening a stop piece and replaced with new ones.
In einer bevorzugten weiteren Ausgestaltung der Erfindung ist vorgesehen, daß das bei Schließstellung des Schiebetores mit dem Ritzel des Antriebs in Eingriff stehende Teilelement aus einem metallischen Werkstoff besteht. Da für die Antriebsmotoren in der Regel Getriebemotoren, insbesondere Schneckengetriebemotoren eingesetzt werden, die bei einer Krafteinwirkung auf das Schiebetor von außen keine Verschiebung ermöglichen, bietet diese Ausgestaltung den Vorteil, daß das Tor in der Schließstellung verriegelt ist und von außen nicht mit Gewalt geöffnet werden kann. Während bei einer vollständigen Bestückung mit Teilelementen aus Kunststoff hier eine Zerstörung der Zähne zumindest über eine Teillänge möglich wäre, bietet die Anordnung eines Teilelementes aus einem metallischen Werkstoff in der vorstehend bezeichneten Weise einen ausreichenden Widerstand gegen eine Gewalteinwirkung auf, so daß eine zuverlässige Verriegelung gegeben ist.In a preferred further embodiment of the invention it is provided that when the sliding gate is in the closed position with the pinion of the drive engaging sub-element consists of a metallic material. Since geared motors, in particular worm geared motors, are used for the drive motors, which do not permit displacement from outside when the sliding gate is subjected to force, this configuration offers the advantage that the gate is locked in the closed position and cannot be opened from the outside by force . While a complete assembly with partial elements made of plastic would destroy the teeth at least over a partial length, the arrangement of a partial element made of a metallic material in the manner described above offers sufficient resistance to the effects of violence, so that a reliable locking is provided .
In Ausgestaltung der Erfindung ist ferner vorgesehen, daß das C-Profil auf seiner Rückenseite mit Durchgangsbohrungen für Schraubenbolzen versehen ist und daß die Breite der Rückennut des Zahnelementes der Schlüsselweite des Kopfes der einzusetzenden Schraubenbolzen entspricht. Hierdurch wird die Montage erheblich vereinfacht, da zum einen bei einem abgelängten C-Profil die Durchgangsbohrung in beliebiger Weise unter Anpassung an die Erfordernisse des zu bestückenden Schiebetores gebohrt werden können. Anschließend werden die Schraubenbolzen von der offenen Seite des C-Profils durchgesteckt und danach die Teilelemente eingeschoben, wobei die Rückennut jeweils den Kopf des eingesetzten Schraubenbolzens formschlüssig umfaßt. Hierdurch wird nicht nur die Bauhöhe des einzusetzenden C-Profils reduziert sondern zugleich auch eine Montagehilfe geschaffen, da das eingesetzte Zahnelement zugleich als Drehmomentaufnahme für den Schraubenbolzen dient, so daß hier die erforderliche Montagemuttern in einfacher Weise aufgeschraubt werden können.In an embodiment of the invention it is further provided that the C-profile is provided on its back side with through holes for screw bolts and that the width of the back groove of the tooth element corresponds to the width across flats of the head of the screw bolts to be used. This considerably simplifies assembly since, on the one hand, with a cut-to-length C-profile, the through-hole can be drilled in any way while adapting to the requirements of the sliding gate to be fitted. Then the bolts are pushed through from the open side of the C-profile and then the sub-elements are inserted, the back groove encompassing the head of the bolt used in a form-fitting manner. This not only reduces the overall height of the C-profile to be used, but also creates an assembly aid, since the tooth element used also serves as a torque holder for the screw bolt, so that the required assembly nuts can be easily screwed on here.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß das Trägerelement auf seiner dem Zahnelement abgekehrten Seite mit einer Hohlschiene versehen ist, an der elektrische Steuerleitungen angeordnet sind und in der ein Schiebeteil geführt ist, das mit einem Ansatz durch einen Längsschlitz nach außen ragt, wobei der Ansatz an einem feststehenden Torteil befestigbar ist und als Anschlußelement für die Steuerleitungen zwischen dem bewegbaren und dem feststehenden Torteil dient. Hierdurch ist die Möglichkeit gegeben, die erforderlichen Steuerleitungen, die die Sicherheitseinrichtungen an Schiebetoren, beispielsweise eine an der Stirnseite angeordnete Kontaktschiene, in das Kraftübertragungselement zu integrieren und einen zuverlässigen Schutz gegen Umgebungseinflüsse jedweder Art zu schaffen. Dadurch, daß das Trägerelement so ausgebildet ist, daß zum einen das Zahnelement, zum anderen aber auch die Steuerleitungen für derartige Schalteinrichungen in einem Bauteil angeordnet sind, ergibt sich hier die Möglichkeit einer werkstattmäßigen Vormontage, so daß vor Ort lediglich das Trägerelement anzuschrauben und die erforderlichen Anschlüsse hergestellt werden müssen. Dies ermöglicht es auch, Reparaturen durch Auswechseln der kompletten Baueinheit sehr schnell auszuführen. Da das Torteil sich zusammen mit dem Trägerelement bewegt, während das Schiebeteil mit seinem als Anschlußelement dienenden Ansatz feststeht, muß für die in der Hohlschiene untergebrachten Steuerleitungen eine Möglichkeit für einen der Bewegungslänge des Torteils entsprechende Längenausgleichsmöglichkeit gegeben werden. Dies kann entweder dadurch bewirkt werden, daß die Steuerleitung bei der Herstellung schraubenförmig gewickelt geformt wird, so daß die Steuerleitung nach Art einer Schraubenfeder elastisch auseinandergezogen werden kann und so die erforderliche Längenänderung zwischen bewegbarem Torteil und feststehendem Ansatzteil gewährleistet ist.In a further embodiment of the invention it is provided that the carrier element is provided on its side facing away from the tooth element with a hollow rail, on which electrical control lines are arranged and in which a sliding part is guided, which projects outwards through a longitudinal slot with a shoulder, the Approach can be attached to a fixed gate part and serves as a connection element for the control lines between the movable and the fixed gate part. This provides the possibility of integrating the necessary control lines, which the safety devices on sliding gates, for example a contact rail arranged on the end face, into the force transmission element and of providing reliable protection against environmental influences of any kind. The fact that the carrier element is designed so that on the one hand the tooth element, but on the other hand also the control lines for such switching devices are arranged in one component, there is the possibility of a workshop pre-assembly, so that only the support element is screwed on site and the necessary Connections must be made. This also allows repairs to be carried out very quickly by replacing the complete assembly. Since the door part moves together with the support element, while the sliding part is fixed with its attachment serving as a connecting element, a possibility for a length compensation possibility corresponding to the length of movement of the door part must be given for the control lines accommodated in the hollow rail. This can either be caused by the control line being helically wound during manufacture, so that the control line can be elastically pulled apart in the manner of a coil spring and the required change in length between the movable gate part and the fixed extension part is ensured.
In einer besonderen Ausgestaltung der Erfindung ist jedoch vorgesehen, daß in der Hohlschiene Führungsmittel für die Steuerleitungen angeordnet sind. Derartige Führungsmittel können beispielsweise durch sogenannte Kabelschleppketten gebildet werden, die im Hohlprofil geführt sind.In a special embodiment of the invention, however, it is provided that guide means for the in the hollow rail Control lines are arranged. Such guide means can be formed, for example, by so-called cable drag chains, which are guided in the hollow profile.
In besonders zweckmäßiger Ausgestaltung der Erfindung ist vorgesehen, daß die Hohlschiene längsteilbar ausgebildet ist und ein Teil als Deckel dient. Diese Anordnung bietet die Möglichkeit, daß auch ohne das gesamte Kraftübertragungselement abmontieren zu müssen, ein freier Zugang zu den Steuerleitungen bzw. den Führungsmitteln für die Steuerleitungen in der Hohlschiene besteht, so daß hier Störungen vor Ort leicht beseitigt werden können.In a particularly expedient embodiment of the invention, it is provided that the hollow rail is designed to be longitudinally divisible and part serves as a cover. This arrangement offers the possibility that there is free access to the control lines or the guide means for the control lines in the hollow rail even without having to dismantle the entire power transmission element, so that faults can be easily eliminated on site.

Wie aus Fig. 1 ersichtlich, besteht ein Schiebetor im wesentlichen aus einem in einer hier nicht näher dargestellten Schiebelagerung geführten Torelement 1, das mit einem Kraftübertragungselement 2 verbunden ist. Das Kraftübertragungselement 2 ist als Zahnstange ausgebildet und steht mit dem Ritzel 3 eines Antriebsmotors 4 in Verbindung. An der Stirnseite 5 des Schiebetores ist eine Sicherheitseinrichtung, beispielsweise in Form einer Kontaktschiene angebracht, durch die sichergestellt werden muß, daß bei der Schließbewegung des Schiebetores der Antriebsmotor sofort abgeschaltet wird, sobald das Tor auf ein Hindernis aufläuft. In der Schließstellung liegt das Torelement 1 an einem entsprechenden feststehenden Pfeiler 6 an. Der Querschnitt gem. Fig. 2 zeigt eine bevorzugte Ausführung für das Kraftübertragungselement. Das Kraftübertragungselement 2 besteht bei der bevorzugten Ausführungsform aus einem Trägerelement 7 in Form eines C-Profils aus Metall, vorzugsweise einem rostfreien Stahl, das über Schraubenbolzen 8 und einen Ansatz 9 mit dem Torelement 1 fest verbunden ist. In das als C-Profil ausgebildete Trägerelement 7 ist ein Zahnelement 10 eingeschoben. Das Zahnelement 10 weist hierbei eine Basis 11 auf, mit der die Zähne 12 verbunden sind. Zugleich sind mit der Basis 11 die Zähne 12 seitlich begrenzende Stege 13 verbunden, die auch mit den Stirnseiten der Zähne 12 einstückig fest verbunden sind, so daß, wie die perspektivische Ansicht in Fig. 4 zeigt, die Basis 11 mit den Seitenstegen 13 und den Zähne 12 ein kastenartiges Profil bilden. Die Zähne 12 sind also nicht nur mit ihrem Fuß sondern auch mit ihren Stirnseiten fest mit der Basis 11 verbunden, so daß hier eine hohe Gestaltfestigkeit gegeben ist.As can be seen from FIG. 1, a sliding gate essentially consists of a gate element 1, which is guided in a sliding bearing arrangement (not shown here) and which is connected to a
Auf der Rückseite der Basis 11 ist ferner eine Rückennut 14 (Fig. 4) vorgesehen, die bei dem dargestellten Ausführungsbeispiel durch zwei längslaufende Stege 15 gebildet wird. Die Breite der Rückennut 14 ist so bemessen, daß sie der Schlüsselweite des Schraubenkopfes 16 des Schraubenbolzens 8 entspricht.On the back of the base 11 there is also a back groove 14 (FIG. 4) which is formed by two
Das Kraftübertragungselement wird nun so aufgebaut, daß zunächst die erforderlichen Durchgangslöcher für die Schraubenbolzen 8 in den gewünschten Abständen gebohrt werden, anschließend die Schraubenbolzen 8 eingesteckt und danach das Zahnelement 10 eingeschoben wird. Das Zahnelement 10 kann hierbei einstückig ausgebildet sein und auf der vollen Länge des C-Profils 7 eingeschoben werden. Es ist jedoch günstiger, das Zahnelement in einzelne Teilelemente aufzuteilen, die nacheinander in das C-Profil eingeschoben werden. Das eingeschobene Zahnelement 10 sichert dann, wie Fig. 2 zeigt, den Schraubenkopf 16 des Schraubenbolzens 8 sowohl gegen Herausfallen als auch gegen ein Verdrehen, so daß anschließend die dargestellten Befestigungsmuttern ohne Hilfswerkzeuge aufgeschraubt und festgezogen werden können.The power transmission element is now constructed so that first the necessary through holes for the
Wie der Längsschnitt in Fig. 3 zeigt, ist das C-Profil 7 des Trägerelementes an seinen beiden Enden mit Anschlagstücken 17 und 18 versehen, die in das Profil eingeschraubt und über querlaufende Schrauben 19 mit dem C-Profil 7 fest verbunden sind. Das Anschlagstück 17 wird als erstes eingesetzt und befestigt. Anschließend werden in der vorbeschriebenen Weise die Schraubenbolzen 8 und die Teilelemente des Zahnelementes 10 in das C-Profil eingeschoben. Anschließend wird ein Preßstück 20 eingeschoben und danach das Anschlagstück 18 mit dem C-Profil verbunden. Das Anschlagstück 18 ist hierbei mit einer axial geführten Spannschraube 21 versehen, durch die über das Preßstück 20 die das Zahnelement bildenden Teilelement im C-Profil fest verspannt werden können. Fig. 3 läßt ferner erkennen, daß ohne das Trägerelement vom Torteil lösen zu müssen, lediglich durch Lösen des Anschlagstückes 18 jederzeit das Zahnelement bzw. einzelne Teilelemente aus dem C-Profil herausgezogen und durch neue ersetzt werden können.As the longitudinal section in Fig. 3 shows, the C-
Fig. 4 läßt erkennen, daß die Teilelemente für das Zahnelement aus einem Kunststoff gegossen, bzw. spritzgegossen werden. Hierzu eignen sich insbesondere Kunststoffe wie Polyacetale, Polyamide, Polytetrafluorethylene oder auch Polyurethane, die die erforderliche hohe Festigkeit aber auch gute Gleicheigenschaften aufweisen.Fig. 4 shows that the sub-elements for the tooth element are cast or injection molded from a plastic. For this purpose, plastics such as polyacetals, polyamides, polytetrafluorethylene or even polyurethanes are particularly suitable, which have the required high strength but also good uniform properties.
Bei der Verwendung von Zahnelementen aus Kunststoff ist es besonders zweckmäßig, wenn das bei Schließstellung des Schiebetores 1 mit dem Antriebsritzel 3 im Eingriff stehende Teilelement aus einem metallischen Werkstoff besteht. In Fig. 1 ist das betreffende Teilelement 22 schraffiert gekennzeichnet. Da der Antriebsmotor 4 als Schneckengetriebemotor ausgebildet und damit selbstsperrend ist, kann das Schiebetor nicht von Hand gegen den Motor verschoben werden. Um nun zu verhindern, daß das geschlossene Tor mit Gewalt unter Zerstörung der Zahnelemente aus Kunststoff zumindest über einen kurzen Weg zur Bildung eines Spaltes aufgeschoben werden kann, bietet die Anordnung eines metallischen Teilelementes 22 für den Bereich der Schließstellung zugleich eine Torsicherung, da es nur sehr schwer ist, selbst über ein großes Hebelwerkzeug die Verzahnung zwischen dem metallischen Zahnelement und dem metallischen Antriebsritzel zu zerstören.When using plastic tooth elements, it is particularly expedient if the partial element which is in engagement with the
Fig. 5 zeigt in einem Querschnitt eine weitere Ausführungsform für das Kraftübertragungselenent. Bei dieser Ausführungsform ist an das beispielsweise als Strangpreßprofil hergestellte C-Profil 7 eine Hohlschiene 23 angeformt. Die Hohlschiene 23 ist hierbei längsteilbar ausgebildet, so daß ein abnehmbarer Deckelteil 24 vorhanden ist, der den freien Zugang zum Innenraum der Hohlschiene bietet. Der Deckelteil 24 ist hierbei so ausgebildet, daß ein Längsschlitz 25 freibleibt, durch den ein Ansatz 26 eines Schiebeteiles 27 nach außen hindurchgeführt ist. Der Ansatz 26 bildet hierbei ein Anschlußelement für eine Steuerleitung, die in der Hohlschiene 23 geführt ist, die mit der Kontaktschiene 5 des Tores einerseits und über den mit einem feststehenden Torteil verbundenen Ansatz 26 mit einer mit dem Antriebsmotor 4 verbundenen Steuer- und Schalteinrichtung verbunden ist. Dies ist in Fig. 1 schematisch über die Darstellung des Ansatzes 26 angedeutet. Der durch die Bewegung des Tores zwischen der Schließstellung und der öffnungsstellung erforderliche Längenausgleich für die in der Hohlschiene angeordneten Steuerleitung wird bei dem dargestellten Ausführungsbeispiel nun dadurch bewirkt, daß die Steuerleitung in einer Kabelschleppkette 28 angeordnet ist, die in der Hohlschiene 23 gehalten ist.Fig. 5 shows in a cross section a further embodiment for the power transmission element. In this embodiment, a
Die Hohlschiene 23 kann aber auch einen im wesentlichen kreisförmigen Querschnitt mit Längsschlitz aufweisen, so daß die Steuerleitung als schraubenförmig-federnd-gewickeltes Element in die Hohlschiene 23 unmittelbar eingelegt werden kann. In der Schließstellung ist die federnde Wicklung auseinandergezogen, während in der Öffnungsstellung die federnde Wicklung zusammengezogen ist.The
Wie Fig. 6 zeigt, bietet das C-Profil 7 ferner die Möglichkeit, das Ritzel 3 des Antriebsmotors 4 mit wenigstens einem Spur- und/oder Tragrand 29 zu versehen, der an einem Rand 30 des C-Profils anliegt. Hierdurch ergeben sich zwischen dem Zahnelement 10 und der Verzahnung des Ritzels 3 definierte, optimierbare Eingriffsverhältnisse, die sich vorteilhaft auf die Lebensdauer auswirken. Zweckmäßig kann es hierbei sein, wenn der Antriebsmotor 4 auf einer Wippe gelagert ist, so daß das Ritzel 3 mit seinem Spurrand mit einer Andruckfeder an das C-Profil abgedrückt wird. Ein Anschlag an der Wippe stellt jedoch sicher, daß ein Mindesteingriff zwischen Ritzel und Zahnelement erhalten bleibt.As shown in FIG. 6, the C-
Statt oder zusätzlich zu einer Andruckfeder kann dem Ritzel in dieser modifizierten Form auch ein Gegenrad zugeordnet werden, das bei entsprechender Ausgestaltung der Befestigungsmittel für das Trägerelement auf der Oberseite des C-Profils läuft. Damit ist das C-Profil zwischen Ritzel und Gegenrad "eingeklemmt", so daß der auf der Wippe gelagerte und mit dem Gegenrad ebenfalls verbundene Motor vom Gegenrad immer nachgeführt wird, wenn beispielsweise das Schiebetor durch Ablagerungen oder Eisbildung auf seinen Laufschienen auf einem etwas höheren Niveau läuft. Das Ritzel steht immer in genau definiertem Eingriff im Zahnelement. Das Zahnelement ist bei dem dargestellten Ausführungsbeispiel vom C-Profil einschließlich der Zähne umschlossen und somit weitgehend geschützt.Instead of or in addition to a pressure spring, a modified counter wheel can also be assigned to the pinion in this modified form, which runs on the upper side of the C-profile if the fastening means for the carrier element are designed accordingly. Thus, the C-profile is "clamped" between the pinion and counter wheel, so that the motor mounted on the rocker and also connected to the counter wheel is always tracked by the counter wheel when, for example, the sliding gate is at a somewhat higher level due to deposits or ice formation on its running rails running. The pinion is always in precisely defined engagement in the tooth element. The tooth element is enclosed by the C-profile including the teeth in the illustrated embodiment and thus largely protected.
