The present In its disclosure, invention builds on every single word and all of the associated words Drawable features of all of these publications on each this characteristic, which can be inferred from the cited documents, is also in the invention applicable or incorporated into them.

Guide rails of translatory drives such as garage door drives must each according to the distance to be covered (translatory drive section) correspondingly long be trained, which makes them and the drives provided accordingly bulky.

The invention has for its object a drive, a traction mechanism and a To design guide rails of the type mentioned in such a way that they, it or he are easy to transport and easy to install even by laypersons. In addition, should a simple transport and assembly process for the drive, the traction mechanism or the guide rail can be created.

This object is achieved by a drive with the features of the appended claim 1, a traction mechanism with the features of appended claim 2, a guide rail with the features of appended claim 3 and a method with the Steps of appended claim 7 solved.

Advantageous embodiments of the invention are the subject of the dependent claims.

According to the invention, the guide rail is in at least two by a folding device individual pieces fastened together.

The folding device advantageously has or is through a hinge educated. Any other flexible attachment such as textile tape, joints, etc. is also conceivable. The complete guide mechanism (guide rail and their associated parts such as slides, end stops, guide or drive wheels, Traction means, see the publications listed above for further details) and / or the door drive is fully pre-assembled. End stops can also be used separately for assembly only to be supplied at the construction site or other installation site. The folded guide rail is then opened at the installation location, whereby additional fastening is carried out at the respective separation point. This is preferable a fastening device on the side opposite the folding mechanism provided which, for example, as a locking device, as a screw fastening, as a screw connection be formed with a tab (bracket) bridging the separation point, etc. can.

If the folding device has a hinge joint (2), then the handling and assembly is particularly easy and the guide rail is still stable because of the hinge joint Folding down only permitted in one degree of freedom, but otherwise the guide rail keeps stable. Unfolding then always leads to the right one Assembly position.

It is also conceivable for the folding device itself to be self-locking when opened State so that folding back is prevented. It is also conceivable that the guide rail unfolded into its operating position due to its attachment to the Mounting location is fixed against collapsing. But the assembly and is easier the construction of the entire device by a connecting device for stabilization of the individual pieces on the side opposite the folding device. The guide rail can then be opened into its operating position before being attached, whereby this operating position is fixed by the connecting device. Then it can the other attachments of the drive, such as in particular the motor housing with an electric motor and lighting devices are installed, whereupon the then fully assembled Drive is attached to its mounting location on the garage ceiling or the like.

Although depending on the embodiment, the folding movement in one to the movement plane vertical plane (for example parallel to the vertical longitudinal median plane of the Guide rail), it is precisely the case with a guide rail in the WO 98/12407 mentioned type advantageous if the guide rail by a folding movement Can be opened and closed parallel to the plane of movement of the driver element is, for example, the folding movement in a horizontal plane with respect to one Properly used door operator installed on the garage ceiling is possible. When folding parallel to the plane of movement, the folding device and a connecting device to be installed opposite the folding device within the on the narrow outer longitudinal sides of this guide rail consistently existing groove. The folding device and the connecting device so do not wear on and can still stabilize the guide rail against bending or deformation from the plane of motion.

The connecting device is or preferably comprises a connecting piece for connecting from the folding device opposite end edge areas of the individual pieces the guide rail, which connector is preferably by a tab or a plate (tongue, bracket ...) with screw openings is formed so that by screwing the tab on each of the individual pieces the guide rail in its unfolded Location is stabilizable.

The invention is preferably produced in such a way that the guide rail for Transport and / or sales or sales with associated interior and / or attachments is preassembled folded down. So the end user only needs the guide rail open and fix and thereby immediately receive the traction mechanism gear for its drive, in some embodiments, the position of the end stops may still be at most is to be adapted to the local conditions. For this reason, is suitable this embodiment especially for distribution through hardware stores or the like Delivery to do-it-yourselfers who do the drive themselves for cost reasons want. On the other hand, it can of course also be used to pay for craftsmen save, since even a craftsman less work with the assembly of the invention Has drive. In the collapsed state, the guide rail can, although it creates a long drive distance, easily e.g. also transport in car trunks. Storage costs can also be saved because the guide rail is less lengthways contiguous storage space needs.

The inventive method for mounting a drive, a traction mechanism or a guide rail according to the invention comprises the steps a) transporting the guide rail or a traction mechanism gear thus formed in preassembled, folded down Condition of the installation site and b) opening and installing the guide rail or the traction mechanism gearbox at the installation site.

A particular advantage of pre-assembling the individual parts of the traction mechanism transmission in the guide rail consists in the fact that a pre-assembled traction device is tensioned by opening it can be.

In a preferred embodiment, the method according to the invention further comprises the steps Stabilize the opened guide rail by fastening the individual pieces with a fastening device, in particular by latching and / or screwing, Possibly via or existing in one piece on at least one of the individual pieces mounting connecting strap.
