Definitions
- the invention relates to a door drive with the features of the preamble of claim 1.
- a door drive of the type in question can be used both to drive the door leaf of a swing door and, although with certain modifications, to drive a door leaf of a sliding door.
- a door drive of the type in question basically includes a drive unit that can be attached to a door frame or to a door leaf and a corresponding abutment that can be attached to the opposite component, that is to say to the door leaf or door frame.
- a force transmission means extends between the drive unit and the abutment and can be moved by motor, that is to say can be extended and retracted, relative to the drive unit.
- the drive element of the drive unit is a drive spindle.
- a drive motor with a drive pinion is used, which acts on the power transmission means designed as a rack.
- a circular rack is also proposed.
- the force transmission means is a link chain with teeth.
- the drive unit has a drive pinion which is driven in rotation by the electric drive motor and forms a transmission connection with the toothing of the link chain.
- this embodiment is distinguished by a particular compactness of the drive unit, since the links of the link chain are located inside a storage space in the housing of the drive unit when the link chain is retracted, that is to say they are rolled up there.
- the link chain is in engagement with a drive pinion which is connected to the electric drive motor in terms of drive technology.
- the drive pinion By turning the drive pinion, driven by the electric drive motor, the link chain is pushed out of the housing of the drive unit or pulled into the housing.
- the link chain When the link chain is retracted, it is largely in the storage space in the housing.
- the link chain When extended, the link chain is exposed between the drive unit and the abutment. In this state, the link chain is freely accessible, it can become dirty, but it also creates a certain source of danger for careless users.
- the link chain runs in a hollow telescopic rod, so that it is not accessible from the outside even when extended.
- the hollow telescopic rod has a fixed telescopic section, which is housed in the housing of the drive unit. At least one further telescope section is displaceable relative to this fixed telescope section.
- the displaceable telescopic section is attached to the abutment with its end remote from the fixed telescopic section.
- the link chain of the power transmission means is longitudinally displaceable inside the fixed telescopic section of the power transmission means. It is connected to the sliding telescopic section.
- the link chain in the fixed telescopic section can thus be displaced in the longitudinal direction.
- the displaceable telescopic section is extended or retracted, depending on the direction of movement of the link chain.
- the link chain itself is protected inside the telescopic rod so that it is neither dirty nor a danger to an operator.
- the housing of the door drive is designed with mirror symmetry with respect to the plane of displacement of the telescopic rod. This means that this door drive can be used for right-hand or left-hand opening.
- the teaching is based on the problem of designing the previously described known door drive to be usable in another way for a right-hand stop or a left-hand stop.
- Swing doors are available with right-hand or left-hand hinges. Sliding doors are also moved in opposite directions. So that the door drive according to the invention can be used universally, the housing has two receptacles lying parallel to one another for the end of the fixed telescopic section, the end of the fixed telescopic section being inserted and held in the one receptacle at the right-hand stop and in the other at the left-hand stop.
- the housing has two receptacles lying parallel to each other, only one of the two receptacles is filled in from the end of the fixed telescopic section. Then there is the possibility that the storage space for the link chain is at least partially formed by the receptacle not occupied by the end of the fixed telescopic section.
- a particularly elegant, structurally expedient version of the door drive according to the invention which is matched to the use of the hollow telescopic rod, is characterized in that the housing is elongated, rectangular, possibly with roundings, in that the inlet openings of the receptacles are arranged on a narrow side of the housing or are and that the drive pinion is arranged near the opposite narrow side of the housing and the link chain there runs behind the drive pinion.
- the drive motor is arranged inside the housing of the drive unit, it being provided that two floors are formed one above the other in the interior of the housing and that the drive motor is on one floor, preferably the lower floor and possibly further components of the drive unit are arranged, while the drive pinion, the link chain, the storage space and the end of the fixed telescopic section are arranged on the other floor, preferably the upper floor.
- the invention relates to a door drive, which in Fig. 1 , 2 and 3 is initially shown overall.
- the door drive has a drive unit 1 which can be attached to a door frame, which is not shown here, and an abutment 2 which can be correspondingly attached to a door leaf.
- the arrangement can also be reversed with the drive unit 1 on the door leaf and the abutment 2 on the door frame.
- the first-mentioned variant is the more common, because then the regularly relatively heavy drive unit 1 does not have to be moved with the door leaf.
- the drive unit 1 is located on a swivel bearing block 3.
- the drive unit 1 itself is opposite this a pivot axis pivotable.
- the pivot bracket 3 is the component that is ultimately firmly attached to the door frame (or on the door leaf).
- the abutment 2 in the present case is also a bearing block which forms a pivot bearing and is then attached to the door leaf (or the door frame) in a fixed manner.
- An extendable and retractable force transmission means 4 extends between the drive unit 1 and the abutment 2.
- the force transmission means 4 has a link chain 5 ( 4, 5 ).
- the drive unit 1 has a housing 6 and in the housing 6 an electric drive motor 7 with a drive pinion 8 connected to the electric drive motor 7 in terms of drive technology. Also on this 4 and 5 are referred to, which reveal the inside of the drive unit 1 of the door drive. It will also be on Fig. 3 referenced, in which the electric drive motor 7 is indicated in the interior of the housing 6. In Fig. 3 one also sees an indicated reduction gear 9 and a transmission shaft 10 to the drive pinion 8.
- the link chain 5 is in engagement with the drive pinion 8 ( 4, 5 ) and can be pushed out of the housing 6 of the drive unit 1 or pulled into the housing 6 by rotating the drive pinion 8.
- the force transmission means 4 has a hollow telescopic rod with a fixed telescopic section 12 and at least one displaceable telescopic section 13.
- the fixed telescopic section 12 is attached at one end to the housing 6 of the drive unit 1.
- the movable telescopic section 13 is attached at one end to the abutment 2.
- the link chain 5 is longitudinally displaceable in the interior of the fixed telescopic section 12. It is connected to the displaceable telescopic section 13, preferably at its end remote from the abutment 2.
- the telescopic pole has more than a longitudinally displaceable telescopic section 13, the link chain 5 is connected to the last displaceable telescopic section 13.
- the link chain 5 is displaceable in the fixed telescopic section 12 by rotating the drive pinion 8. Since it is connected to the inner end of the displaceable telescopic section 13, the displaceable telescopic section 13 is thereby displaced with respect to the fixed telescopic section 12 and extended or retracted with respect thereto.
- Fig. 4 shows the retracted position while Fig. 5 shows the extended position.
- Fig. 1 and 2nd the retracted position is shown in solid lines, the extended position in dash-dotted lines.
- the housing 6 of the drive unit 1 has a receptacle 14 for the end of the fixed telescopic section 12, in which the end of the fixed telescopic section 12, preferably removable, is held.
- Fig. 1 shows for the embodiment of this embodiment according to the invention that the housing 6 has two receptacles 14 lying in parallel.
- the end of the fixed telescopic section 12 can be inserted into one receptacle at the right stop and into the other receptacle 14 at the left stop.
- the end of the fixed telescopic section 12 of the telescopic rod is inserted into the receptacle 14 on the right.
- Fig. 4 shows in connection with Fig. 5 that the drive unit 1 is constructed according to the invention in such a way that the storage space 11 for the link chain 5 is at least partially formed by the receptacle 14 not occupied by the end of the fixed telescopic section 12.
- a symmetrical structure of the housing 6 with the drive pinion 8 enables this skillful use of the interior of the housing 6.
- the insertion of the end of the fixed telescopic section 12 into the housing 6 is easily possible according to the invention in that a cover 15 of the housing 6, which in Fig. 1 can be seen particularly well, is unscrewed. Then the end of the fixed telescopic section 12 can be inserted from above into the receptacle 14 in the housing 6. Then the cover 15 is screwed back on and the end of the fixed telescopic section 12 is fixed in the housing 6. With the cover 15 removed, the link chain 5 can also be conveniently inserted or removed.
- the housing 6 is elongated, cuboid and here with roundings, that the inlet openings of the receptacles 14 are arranged on a narrow side 16 of the housing 6 and that the drive pinion 8 is close to the opposite narrow side 17 of the housing 6 is arranged and the link chain 5 runs there behind the drive pinion 8.
- Fig. 3 and 4th can be seen in connection with how the housing 6 of the drive unit 1 of the door drive according to the invention could be made relatively compact. This is because it can be seen here that two levels are formed one above the other in the interior of the housing 6 and that the drive motor 7 and possibly further components of the drive unit are arranged on one level, here and preferably the lower level, while on the other level, here and preferably the upper floor, the drive pinion 8, the link chain 5, the storage space 11 and the end of the fixed telescopic section 12 are arranged.

Ein Türantrieb der in Rede stehenden Art ist sowohl für den Antrieb des Türblattes einer Drehflügeltür als auch, wenn auch mit gewissen Modifikationen, zum Antrieb eines Türblattes einer Schiebetür einsetzbar.A door drive of the type in question can be used both to drive the door leaf of a swing door and, although with certain modifications, to drive a door leaf of a sliding door.
Zu einem Türantrieb der in Rede stehenden Art (z. B.
Im zuvor genannten Stand der Technik werden ausführlich verschiedene Arten von Türantrieben beschrieben. Bei einer ersten Alternative ist dort das Antriebselement der Antriebseinheit eine Antriebsspindel. In einer weiteren Alternative wird ein Antriebsmotor mit einem Antriebsritzel eingesetzt, der auf das als Zahnstange ausgeführte Kraftübertragungsmittel wirkt. Auch eine kreisbogenförmige Zahnstange wird vorgeschlagen. In einer weiteren Alternative ist das Kraftübertragungsmittel eine Gliederkette mit einer Verzahnung. Die Antriebseinheit weist ein Antriebsritzel auf, das vom elektrischen Antriebsmotor drehend angetrieben wird und mit der Verzahnung der Gliederkette eine Getriebeverbindung bildet. Im Stand der Technik wird zu dieser Variante darauf hingewiesen, dass sich diese Ausgestaltung durch besondere Kompaktheit der Antriebseinheit auszeichnet, da die Glieder der Gliederkette sich bei eingezogener Gliederkette im Inneren eines Aufbewahrungsraumes im Gehäuse der Antriebseinheit befinden, also dort gleichsam aufgerollt sind.Various types of door drives are described in detail in the aforementioned prior art. In a first alternative, the drive element of the drive unit is a drive spindle. In a further alternative, a drive motor with a drive pinion is used, which acts on the power transmission means designed as a rack. A circular rack is also proposed. In a further alternative, the force transmission means is a link chain with teeth. The drive unit has a drive pinion which is driven in rotation by the electric drive motor and forms a transmission connection with the toothing of the link chain. In the prior art for this variant, it is pointed out that this embodiment is distinguished by a particular compactness of the drive unit, since the links of the link chain are located inside a storage space in the housing of the drive unit when the link chain is retracted, that is to say they are rolled up there.
Im zuvor genannten Stand der Technik werden ausführlich Ausgestaltungen eines Türantriebs der in Rede stehenden Art beschrieben. Es handelt sich dabei um Ausgestaltungen einer Rutschkupplung, einer Steuerungselektronik, einer Drehzahlüberwachung, einer Programmierung, einer drahtlosen Fernbedienung, einer gekuppelten Betätigung einer Türfalle oder eines Türriegels etc. Ferner werden verschiedene Ausgestaltungen des elektrischen Antriebsmotors und verschiedene Getriebevarianten erläutert.In the aforementioned prior art, embodiments of a door drive of the type in question are described in detail.

Insgesamt wird für die Offenbarung von möglichen Varianten der Ausgestaltung eines Türantriebs der in Rede stehenden Art auf die
Bei dem zuvor behandelten Stand der Technik steht die Gliederkette mit einem Antriebsritzel im Eingriff, das mit dem elektrischen Antriebsmotor antriebstechnisch verbunden ist. Durch Drehen des Antriebsritzels, angetrieben vom elektrischen Antriebsmotor, wird die Gliederkette aus dem Gehäuse der Antriebseinheit heraus geschoben oder in das Gehäuse hinein gezogen. Im eingefahrenen Zustand befindet sich die Gliederkette zum großen Teil im Aufbewahrungsraum im Gehäuse.
Im ausgefahrenen Zustand liegt die Gliederkette frei zwischen der Antriebseinheit und dem Widerlager. In diesem Zustand ist die Gliederkette frei zugänglich, sie kann verschmutzen, bildet aber auch eine gewisse Gefahrenquelle für unvorsichtige Benutzer.In the prior art discussed above, the link chain is in engagement with a drive pinion which is connected to the electric drive motor in terms of drive technology. By turning the drive pinion, driven by the electric drive motor, the link chain is pushed out of the housing of the drive unit or pulled into the housing. When the link chain is retracted, it is largely in the storage space in the housing.
When extended, the link chain is exposed between the drive unit and the abutment. In this state, the link chain is freely accessible, it can become dirty, but it also creates a certain source of danger for careless users.
Das zuvor aufgezeigte Problem ist bereits, einer Lösung zugeführt worden (
Bei dem Stand der Technik, von dem die Erfindung ausgeht, ist das Gehäuse des Türantriebs hinsichtlich der Verschiebeebene der Teleskopstange spiegelsymmetrisch ausgestaltet. Dadurch kann dieser Türantrieb für Rechtsanschlag oder Linksanschlag eingesetzt werden.In the prior art, from which the invention is based, the housing of the door drive is designed with mirror symmetry with respect to the plane of displacement of the telescopic rod. This means that this door drive can be used for right-hand or left-hand opening.

Hat das Gehäuse zwei zueinander parallel liegende Aufnahmen, so wird nur eine der beiden Aufnahmen jeweils vom Ende des feststehenden Teleskopabschnittes ausgefüllt. Dann ergibt sich die Möglichkeit, dass der Aufbewahrungsraum für die Gliederkette zumindest zum Teil von der nicht durch das Ende des feststehenden Teleskopabschnittes besetzten Aufnahme gebildet ist.If the housing has two receptacles lying parallel to each other, only one of the two receptacles is filled in from the end of the fixed telescopic section. Then there is the possibility that the storage space for the link chain is at least partially formed by the receptacle not occupied by the end of the fixed telescopic section.
