Description

The The invention relates to either by hand or by engine operation gate to be driven with a movable door leaf and a so geared connected Torwelle, which is when moving the door leaf rotates.

The DE 203 20 842 U1 shows in her 5 and 6 an example of such a gate in the form of a sectional door with a formed of a plurality of hinged together by means of hinged panels panels and a weight balancing device having a torsion spring with a torsion spring.

It is already common To connect to such Torwellen door drives, so as to drive the gate directly. For this Connection is the Torwellenende both sides on the storage of the door shaft out. This is necessary to a door operator either on one connect the ends of the door shaft to be able to.

Currently Toroidal shafts on the market consist of several shaft parts, which are joined together by a clutch. At the Torwelle also uses a torsion spring for the weight balance of the gate. The Torwellen are therefore synonymous used in such gates, which are hand-operated.

The DE 298 17 616 U1 as well as the DE 102 59 771 B show such Torwellen with connected to the protruding ends gate drives. These known Wellentorantriebe are already designed so that they require as little lateral space.

The space requirement of Torwellen with drives can be a problem in many places, therefore, the Wellentorantriebe the DE 102 59 771 B4 as well as the DE 298 17 616 U1 optimized for their lateral space requirements.

The DE 43 37 366 A1 proposes, depending on the space requirement, either to set up the Wellentorantrieb itself directly on the Torwellenende, or to provide different transmission elements, which have correspondingly lower axial space requirements.

Of the However, space can also with manual motors with such Tor waves pose a problem. So are conditions at the installation site not uncommon, where the standard used Toroidal waves for connection a door drive each have left and right a board, from its axial length do not fit.

The DE 203 11 618 U1 describes a Wellentorantrieb, which is also suitable for Torwellen in which the Torwellenende not projecting laterally. For this purpose, a plug-in mounting is provided instead of a plug-on mounting for the door drive. However, this is problematic because there are special forms for many gate shafts, in each case only the outer dimension of the door shaft is determined.

The Inside of the mostly tubular However, trained Torwellen can considerable from Torwelle to Torwelle Have positional deviations. A safe coupling of the door drive to arbitrarily configured Torwellen is therefore not with this construction possible.

The DE 20 2004 01 4167 U1, in turn, is taking a different approach Drive motor is integrated directly in the Torwelle itself. These and other solutions However, they are always very expensive special solutions that are not for the industrial Mass production are suitable.

The DE 40 24 666 A1 describes a generic gate with a door shaft and connected to a side board of the door shaft Wellentorantrieb. In this case, a total of two shaft parts are joined together by means of a coupling to the entire door shaft. This coupling is still associated with a catching device with a centrifugal pawl which locks the door shaft at too fast rotation of the door shaft.

Out WO 95/34764 is another coupling for connecting two Partial waves of a Torwelle described.

It Therefore, there is a need an optional manual or motor operated gate to manufacture with a Torwelle such that it is inexpensive in high volume can be produced, is universally applicable and with few and simple Handles adapted to the existing installation situation is.

The Invention has set itself the task of a gate of the aforementioned Kind available to make that easily and inexpensively in mass production is, in which the drive shaft optionally a drive can be connected and that can still be installed in tight spaces or at the unnecessary Material can be saved.

These Task is solved by a gate with the features of claim 1. Advantageous embodiments The inventions are the subject of the dependent claims. A drive kit for such Goal is the subject of the secondary claim.

According to the Torwelle is längenver changed in such a way that in a first, short position, the door shaft is not or only slightly protruding laterally and in at least a second, longer position, the door shaft projects laterally beyond the mounting for connecting a door drive.

In a preferred embodiment here is an intermediate piece for one Coupling between two Torwellenteilen provided. At the delivery of the gate without drive, the intermediate piece is omitted. Will be in addition desired a door drive, would additionally that connecting piece delivered to thereby produce a board of the Torwelle.

The Torwelle preferably has a special cross-section with a separate executed Groove in which a connection piece for the Door drive positive locking is receivable. The connection piece then becomes radially outside placed on the Torwellenende.

It can be an assortment of different, especially different thick spacers be present, or it can be depending on space requirements several intermediate pieces next to each other which are screwed with flanges of the coupling and so the length change the Torwellen.

One Drive kit for driving such a door then preferably has a motor driving device for rotationally driving the door shaft and a device for lengthening the Torwelle on. The motor drive device has a connection device for encompassing attachment of a projecting end of the door shaft. By attaching the manufactured with relatively tight tolerances outer contour the door shaft for be used the drive connection. This will be a secure connection allows. The device for extending the door shaft is preferably formed by at least one spacer, that for insertion between two sub-elements of the gate already existing door shaft for extension the door shaft is formed. The drive kit can also several spacers added be.

If the spacer at least a first fastener for attachment to a first Part element and at least a second fastening element for fastening to the second sub-element, wherein the at least one first fastening element and the at least one second fastening element elastically with each other are connected, irregularities in the course of the Torwelle, In particular, compensate for a non-circular run or torque surges on one of the sub-elements and / or steam. For example, could the spacer a disc formed of a rubber material with a first and a second group of openings be which screw fasteners record and the first and the form second fasteners. This made of a rubber lateral formed pane then acts as a kind of "hard disk", as in the automotive industry used in cardan shafts to absorb bumps and hard knocks becomes.

One embodiment The invention will be explained in more detail with reference to the accompanying drawings. In this shows:

1 a Torwelle designed as a torsion spring shaft for a gate, which is set for a manual operation of the door in a first, short length adjustment;

2 the door shaft of 1 , which is set for a motor operation in a second, longer length setting, with a schematically illustrated connected drive;

3 a drive kit for a gate, a Torwelle according to the 1 or 2 having;

4 a view in the axial direction of a spacer, which for length adjustment of the Torwelle according to the 1 or 2 is usable; and

5 a gate with a door shaft according to the prior art.

5 shows a total of 10 designated gate in the form of a sectional door with a door shaft 12 According to the state of the art. This gate 10 According to the prior art corresponds approximately to that from the DE 102 59 771 B4 known gate. It is therefore referred to this document for further technical details. The Torwelle 12 is made up of two partial waves 14 . 15 formed, which by means of a coupling 16 are connected together for common rotation. The coupling 16 is like from the EP 0 766 794 B1 well known.

Every partial wave 14 . 15 has a tubular profile, which is closer in the DE 102 597 71 B2 . 2 is shown. The Torwelle 12 is by means of several bearing blocks 18 Stored fixed and points to each of the partial waves 14 . 15 one cable drum each 20 and a torsion spring 22 on. At every rope drum 20 is in each case a first cable pull 24 for pulling up a door leaf 30 of the gate 10 and a second cable pull to pull down the door leaf 30 kept wound up. About the cables 24 . 26 is the door leaf 30 geared with the Torwelle 12 connected. The Torwelle 12 is used in particular for weight balance for the opening in the vertical direction door leaf 30 ,

To a connection of a Wellentorantriebes 32 to the door shaft 12 to allow both Torwellenenden stand 35 . 36 with her in the DE 102 59 771 B1 closer profile shown axially before. In the example shown, the Torwellenenden 34 . 35 over the outside mounted bearing blocks 18 in front. On one of the two above Torwellenenden 34 . 35 is then the Wellentorantrieb by means of an externally placed on the Torwellenende connection element 38 connected, as closer in the DE 102 59 771 B4 is explained.

Based on this prior art will be described below with reference to the 1 and 2 described a new door construction. The same reference numbers are used for corresponding elements and the description of the elements is not repeated. The new door construction results from replacing the door shaft 12 through the in 1 and 2 illustrated Torwelle 40 with shorter partial waves 41 and 42 , where the door shaft 40 but is variable in length.

1 shows a first length setting for a manual operation of the gate 10 , The part waves 41 . 42 are so shortened that the Torwellenenden 34 . 35 not, or as shown protrude only slightly. The Torwellenenden 34 . 35 Stand here just so far that a safe position relative to the axially furthest outward on the Torwelle 40 attacking element, here the respective bearing block 18 , is guaranteed. For example, the Torwellenenden stand 34 . 35 only one or a few millimeters before. As a result, axially laterally of the door shaft 40 Saved space. The new door construction can therefore be easily used in manual operation even in confined spaces.

2 shows the door shaft 40 in a second length setting for a motor operation with connected shaft gate drive 32 ,

The coupling 16 is how this is closer from the EP 0 766 794 B1 emerges, with two disc elements 44 . 46 provided, which by means of screws 48 , as in 1 represented, can be screwed together. To extend the door shaft 40 according to 2 is between these two disc elements 44 . 46 attached a spacer. The spacer 50 is here formed by a disk 52 made of elastic material. How out 4 it can be seen which the disc 52 in axial plan view, are in the disc 52 drilling 54 for receiving the screws 48 intended. So the spacer is on both sides with the disc elements 44 screwed.

By inserting the spacer 50 between the two disc elements 44 . 46 the clutch 16 can the Torwelle 40 so extend that the Torwellenenden 34 . 35 protrude - or only the Torwellenende to be used for the Torantriebanschluss 35 protruding - so as to put on, the connecting element 38 to enable.

In 2 the second length adjustment is shown such that both gate shafts 34 . 35 protrude. As by the dashed line 56 implied, could be the spacer 50 be formed with a smaller axial length. One achieves that only the respective Torwellenende 34 or 35 , on which the motor connection is to take place, protrudes.

3 shows a drive kit for driving one with the Torwelle 40 according to 1 provided gates 10 , The drive kit 56 has a motor drive device in the form of Wellentorantriebes 32 with the connection element 38 and in this example, several of the spacers 50 on. The Wellentoran drove 32 and the connection element 38 are like from the DE 102 59 771 B4 built closer. The partial waves 41 . 42 have this in this document in 2 detailed profile. The two spacers 50 and 58 have different axial lengths here. Instead, two equal, thinner spacers could be used 58 attached, which in series between the disc elements 44 . 47 can be fixed in the axial direction one behind the other.

Because of the disc 52 which the respective spacer 50 . 58 made of an elastic material, it acts like a hard disk in cardan waves of automobiles for damping and absorbing shocks and for compensating for a non-round Torwellenlaufes. In particular, by the attack of the torsion springs 22 Such a run-out and an egg of the Torwelle arise.

Instead of in DE 102 597 771 B4 connection option shown, the Wellentorantrieb 32 Depending on the space available, different gearboxes can also be connected directly to the door shaft to the projecting door shaft end 34 respectively. 35 be seated attached, as in the DE 43 37 366 A1 is explained in more detail. Also, the corresponding transmission can individually or together parts of the drive kit 56 be. In embodiments not shown, it is also possible to provide different spacers for the various gear, so as an axial board of Torwellenendes 34 . 35 to adapt to a specific need of one of the gearboxes. For example, the transmission could be provided with connecting elements with different axial dimensions, to which the board of Torwellenendes 34 . 35 adjusted by a suitable spacer.
