GATE FOR GARAGES, HALLS or the like.

The invention relates to a door for garages, halls or the like, whose can be raised and lowered **? * door leaf from several slats that are articulated to one another via horizontal axes; which is guided on rollers in rails.

In order to be able to open and close such gates, Antrlebd used, who usually use rope or chain pulls, wenrr « gears and racks can also be used as power transmission means. For goals, the door leaf in itself is rigid, drive motors are used, which are fixed to the door leaves and have two shafts and federge = Tensioned slip-on couplings put friction rollers into circulation, which move along the intended running rails, with further means ensure that each friction roller rests against the inner rail surface.

The invention is based on the object of providing a drive for gates, the liftable and lowerable door leaves of which consist of several slats articulated to each other about horizontal axes, which are guided over rollers in rails and which are designed as a friction roller drive. '■. is formed. The aim is to ensure that the to move in

Friction roller drives used for rigid door leaves are also used as drive means for door leaves consisting of slats can be used to not only simplify storage, but also because of the higher number of pieces To reduce manufacturing costs of such drives. In order to solve this problem, it is proposed according to the invention, in the above Area of the door leaf in the closed position, two coaxial, known per se, of one on the door leaf specified motor drivable, by means of spring-loaded slip-on couplings easily removable shafts to be arranged on their free ends each a friction roller or the like is fixed and each of these friction rollers or the like two other rollers or the like, assigned, which are each mounted on a lever that can be pivoted about the corresponding drive shaft, and to ensure that the free ends of these levers are connected to one another via at least one spring that crosses the respective drive shaft stand. The friction wheel drives, which are used to move rigid door leaves, can also be used for louvre doors are used and the two friction rollers assigned to these drives only need to be assigned two additional rollers each, which presses the friction roller between them against the inner surface of the running rail. Because lamellar doors are balanced are, it is not necessary to preload the springs influencing the other roles to different degrees, it can the same springs are always used. Since the friction rollers are at the beginning of the opening of the slatted door and at the end when closing the louvre door are always located where the vertical track parts extend about a curvature in which is essentially horizontal extending running rail parts pass over, the other Springs assigned to rollers are more tensioned than when they are in straight parts of the rails, so that the friction rollers fixed on the drive shafts

here relatively strong against the corresponding rail surfaces be pressed so that the drive can exert a correspondingly greater thrust. That is why this is special Useful because the largest when the gate starts, i.e. when it begins to open and when it ends Force is needed. The assignment of the other roles to a friction roller each presents no difficulties and the As with the known drives, the drive can be uncoupled by removing the drive shafts in the event of malfunctions.

The invention is illustrated schematically with reference to one in the drawings illustrated embodiment explained below.

It shows:

Figure 1 is a view of a closed lamellar door seen from the closed room,

FIG. 2 shows a cross section through the closed gate according to FIG. 1,

FIG. 3 shows an enlarged illustration of part of a Running rail with its associated friction rollers in two positions of the door leaf without the door.

The door 1 consists of several slats 2 articulated to one another via a horizontal axis, which are guided via rollers 3 in running rails 4 and 5, which form a part 5 ′ ¹ extending in the perpendicular and which interlock via a curved part 5 ″ In the upper area of the door leaf in the closed position, there are two coaxial, known per se, one on top leaf 1

fesfc. laid motor 6 drivable by means of not shown Spring-loaded slip-on couplings easily removable shafts 7 and 8 are arranged, each with a friction roller at their free ends 9 or 10 is set.

Each of these two friction rollers or the like 9 and 10 are assigned two further rollers or the like 11 and 12, which are also guided in the running rails h and 5. Each further roller 11 or 12 is mounted at the free end of each lever 13 or 1Ί, which are pivotable about the corresponding drive shaft 7 and 8 and both are under the action of a spring 15 that engages over the corresponding drive shafts.

If the door is in the closed position and the drive motor 6 is now switched on, then viie friction rollers 9; 10, which are in the curved part of the rails H and 5, set in rotation and then take, as' they through the other rollers

11 and 12 against the inside-running surfaces 16 of the rails ¹ and I 5 are pressed, the gate with is worn until it substantially from the horizontally extending running rail members 5 ''. During this movement of the friction rollers, the two springs 15 relax as well as they get into the horizontally extending running rail ^{parts 5 11} (FIG. 3, right part). In the horizontally running track parts, the friction rollers 10 are in any case firmly enough on the running surfaces 16 due to the weight of the lamellar door, so that these friction rollers do not need to be pressed particularly hard.

Of course, the other roles can od. Like. 11 and

12 can also be stored in a different way than the exemplary embodiment shows, because it is only essential that these further rollers, the drive friction rollers 9, 10 in the curved part 5 ^{111 of} the running rails 4 and 5, are firmly attached to the running surfaces

pressing the means by which this is achieved is in itself secondary. _ _A ^ <i
