Description

The The invention relates to a door drive with the features of the preamble of the appended claim 1. In addition concerns the invention is an actuating element for a Such door drive and provided with such a door drive Gate, in particular roller door.

Such a door drive with the features of the preamble of claim 1 is known from Product catalog of the company GfA-Gesellschaft für Antriebstechnik, Dr.-Ing. Hammann GmbH & Co. KG with the imprint 6.2007 sheet 1.31 known. Next is such a door drive from the Company publication "Operating Instructions - Gate Openers" A 315/112 from Becker-Antriebe GmbH with the imprint 2353 300 033 0 12/01 EN dated December 2001 known.

Comparable door drives and thus driven roller shutter are from the Company publication "Rolltore and Rollgitter" of the company Hörmann KG sales company with the printing note S. 06.08 / D. 06.08 / HF 84555 / G.xx known. In this document various roller doors are described. Such a roller door has as a door leaf formed from a plurality of mutually articulated hinged slats curtain, which is wound on a door shaft in the form of a winding shaft. To the winding shaft, a door drive in the form of a Wellentorantriebs is connected. Preferably, for this purpose, a Wellentorantrieb is used, which also has a provided with a self-locking gear in addition to an electric motor.

Around the gate also in emergencies or incidents, in particular during power outages, or in other situations where no electricity is available to move, the known door drives are provided with a manual override. The manual overrides have an actuator on, which can be coupled with a drive shaft of the door drive is to manually rotate this drive shaft.

For example is a motor shaft as a drive shaft with a connection coupling provided for the actuator.

As an actuating element for the known door drives is a hand crank, as shown for example in the attached here 3 is shown. 3 shows as an actuator for a manual actuator 50 used crank 100 , which at one end with a handle 102 is provided to a cylindrical area 108 at an intervention end 104 to turn. This intervention end 104 can be used in an opening on the door drive and has a coupling training 16 on, which acts on a connection coupling of the door drive. For this purpose, the coupling training 16 a transverse groove 110 at the end of engagement 104 on. The coupling formation of the door drive (not shown) has a corresponding projection which fits into the transverse groove 110 engages, so about turning the crank 100 the drive shaft of the door drive is rotatable. For ease of insertion of the engagement end 104 and a simplified centering is still a bevel 112 intended.

Such a crank 100 is at least partially ergonomically unfavorable. For example, the space available on the door drive is limited, so that an insertion of the crank and in particular a turning of the crank is unwieldy.

at the known Torantrieben is a hand crank for such purposes provided with universal joint, which is costly.

Of the Invention is based on the object, a door drive with manual override according to the preamble of the attached Claim 1 to improve such that the manual operation direction easier and less expensive to produce and also easier to operate in unfavorable space conditions is.

These Task is achieved by a door drive according to claim 1 solved.

One Actuator for the manual actuator Such a door drive is the subject of a secondary claim. A door provided with such a door drive, in particular a roller door, is the subject of further additional claim.

advantageous Embodiments of the invention are the subject of the dependent claims.

According to the invention the actuator, which for manual rotation of the Torantriebes is used, a tool attack for rotationally fixed Attack of a standard tool.

The tool attack is preferably carried out standardized according to relevant tool standards. In particular, a square or hexagonal training is provided, which can be reliably detected with standard commercial wrenches or standard nuts. For example, one is on the wrench size 17 (or another key width) standardized hexagon provided.

Such tool training can be safely detected by standard tools. Such standard tools are especially useful the installation of the door drive or the door, but also in most other to be closed by such doors to be closed rooms anyway or easily procured by the end user.

For Such standardized tool attacks are abundant of tools that turn even in unfavorable installation situations enable. For example, there are ratchet sets, the extensions, universal joints, cranks and in particular have powerful ratchets. Leave it even in confined spaces by means of the actuator and a corresponding ratchet easily turn the drive shaft manually.

Further There are also connections for drills or like machine tools and cordless screwdrivers, so that too one Machine operation with an external machine tool is possible.

• • Das Betätigungselement kann kleiner, leichter und formschöner gestaltet werden.
• • Das Betätigungselement lässt sich durch entsprechend standardisierte Werkzeuge ergonomisch günstiger betätigen.
• • Das Betätigungselement ist bedeutend platzsparender. Beispielsweise bietet es geringeren Sturzanschlag und geringeren Seitenanschlag.
• • Das Betätigungselement lässt sich bedeutend kostengünstiger und preiswerter herstellen.

Particular advantages of embodiments of the actuating element according to the invention in comparison to the emergency hand crank according to 3 are in particular:

• • The actuator can be made smaller, lighter and more shapely.
• • The actuator can be operated ergonomically cheaper by correspondingly standardized tools.
• • The actuator is significantly more space-saving. For example, it offers lower fall stop and lower side stop.
• • The actuator can be significantly cheaper and cheaper to produce.

Preferably, the actuating element has at one end a coupling formation for the rotationally fixed detachable coupling to the connection coupling of a manual actuation device of a door drive. The actuator can, for example, with a corresponding coupling training 16 like the hand cranks used so far 100 be equipped and can be so easy instead of the hand crank 100 be used with each corresponding door drive.

A simple shape results when the actuator simply designed as a rod or shaft and attached to one of his Ends the coupling training and at the other end the tool attack having. In such a form, the actuator can be easy to handle like an extension of a ratchet.

Preferably the shaft is thinner than the tool attack, allowing it to easily fit in a coupling opening in a housing a door drive is used and can be performed there. Will be a tool attack with a larger diameter selected, so can higher torques easier and cheaper to transfer materials become.

The Actuator is preferably much shorter executed as the hand cranks previously used. Therefore is a between the coupling training and the tool attack extending shank preferably equal to or less than about 150 mm educated.

Around a rotary guide in the coupling opening of Manual actuator known gate drives also at To ensure ratchet operation is the shaft more preferably at least about 50 mm long.

To the Coupling to the connection coupling of existing door drives is the Coupling training of the actuating element preferably with a central transverse groove at the insertion end of the cylindrical provided trained shaft.

If the tool attack is hollow inside, material can be saved become. Preferably, the tool engagement is with an axial bore or opening provided so that a variety of tools can be used. In particular, is also a square or hexagon socket provided to use also Imbusaufsätze or Allen tools to be able to.

Of the Door drive is preferably designed as Wellentorantrieb, the for driving a Torwelle provided gate.

The Actuator is preferably as an adapter for connection a standard ratchet nut formed on such a door drive.

Preferably the door is a roller shutter or rolling grille.

Just for roller shutters or rolling grilles, but also for others with door shaft provided gates is a manual during assembly Rotatability of the Torwelle advantageous. Often at the construction site is still no electricity available; or the door drive can only be insufficient control manually. But during assembly it is also necessary that the door shaft is rotated several times short and precise. For example Rolltoren is a short winding and unwinding of the roller table hanger in the course of hanging installation and / or threading the curtain in guide rails or the like necessary.

For this purpose, the actuating element for manual operation is particularly suitable. The mechanic can then with his ratchet and a corresponding Torque the door drive manually for a short time. In the then present rotational position then the gear acts again self-locking, so that in this position further assembly work can be performed.

The The idea presented here also includes the use of the door drive and / or the actuating element during assembly of a Gates, in particular roller shutters.
