Rolling door, ceiling shutter door or the like.

The invention relates to a roller shutter, ceiling-mounted sectional door or the like consisting of individual profiles which are connected to one another in an articulated manner and which are guided in laterally arranged guide rails.

In the case of roller doors or ceiling-mounted sectional doors, such as those used to close a garage, a door consisting of individual profiles is guided in lateral guide rails, whereby the door is first moved vertically upwards to open, then deflected by 90° and then placed horizontally under the ceiling in the garage. Such doors can be equipped with a weight compensation that ensures easy opening and closing, and an electric drive can also be installed to close or open the door. The profiles of the door interlock so that a

A complete door is made up of profiles that are connected to one another in a form-fitting manner and are held together with flexible joints. The places where the individual profiles interlock are called profile eyes. These profile eyes have play in relation to one another, either for manufacturing or assembly reasons, or because they are also used in roller doors where this play is desired.

With ceiling-mounted sectional doors, this play between the profiles is undesirable and can even be harmful. This is because when the ceiling-mounted sectional door is operated, the individual profiles are pulled apart as they move upwards and are then placed horizontally under the ceiling. When the door is now closed, the electric drive pushes the horizontally positioned profiles towards the door opening, so that the profiles are pushed together again, similar to an accordion effect. If a number of individual profiles have moved beyond the guide rail arch into the vertical position, the weight of the vertical profiles is sufficiently high that the profiles still lying horizontally under the ceiling are pulled apart, which is more or less like a domino effect, until the profiles are at the maximum distance from each other. The door is therefore very loud when it moves, as the profiles hit their end positions and the door is also caused to swing.

This gives rise to the object underlying the invention, a

Roller shutter, ceiling-mounted sectional door or similar in such a way that a

enables silent movement from the horizontal position to the vertical position and back again.

This object is achieved according to the invention in that elastic or fixed spacer elements are arranged between the articulated individual profiles, which ensure that the individual profiles move in relation to one another in the guideway of the guide rails without play. As a result of the invention, this is prevented in a simple and cost-effective manner by either clamping the individual profiles in such a way that the play between the individual profiles is always

is zero, or the play is reduced by a spacer, a virtually silent movement of the articulated individual profiles in the angled guide track can take place. The spacers also ensure that it is possible to use classic roller shutter profiles, for example, which usually have a very high play in the profile, particularly for ceiling sectional doors. The use of spacers also effectively prevents the profile eyes from moving within the play, whereby ceiling sectional doors equipped in this way then run exceptionally quietly and smoothly.

According to a particularly advantageous embodiment of the invention, the spacer is designed as an intermediate layer which is arranged in the area of the radii of curvature of the interlocking hook-shaped strips of the individual profiles. The intermediate layer acts precisely at the point where the articulation point of the individual profiles positioned relative to one another has its maximum play, namely at the point where the profile eye is at its greatest distance when it passes through the 90° bend. Incorporating an elastic or fixed layer in this area ensures that the play between the two profiles in the curved area of the guide rail is dampened and controlled, with the layer being inserted into the radius of curvature of the hook-shaped profile strips. Thus, when, for example, the two individual profile strips which are held in an articulated manner relative to one another are guided through the curved area of the guide tracks which are at an angle to one another, these are held at a fixed distance from one another, so that the play between the two profile strips is reduced or reduced to zero.

According to a particularly advantageous development of the invention, the spacer is an elastically curved tab that is attached to the individual profiles at the front or back, covering the joint area. In this way, the curved tab keeps the individual profiles that are positioned relative to one another at a distance so that the hook-shaped strips remain in their curved seat.

According to a further embodiment of the invention, this is also achieved in that the spacer is a helical spring which is arranged between the front sides of the individual profiles. The helical spring thus presses the two individual profiles, which are held in an articulated manner, apart so that the curved hook strips are pressed into one another, so that an elastic distance is also achieved, with the individual profiles being held in a form-fitting manner in one another.

An embodiment of the invention is explained in more detail with reference to the following figures 1 to 3, in which:

Figure 1 shows a schematic representation of a roller door, ceiling-mounted sectional door 1, which consists of individual profiles 2 connected to one another in an articulated manner. The profiles 2 are guided in guide rails 3 arranged on the sides. The enlarged detailed views of Figure 1a and Figure 1b show the situations when the individual profiles 2 slide through the curved path 4 of the guide rails 3 using an elastic or fixed spacer element 5. As can be seen from the figures, the spacer elements 5 are arranged between the individual profiles 2 connected to one another in an articulated manner, which allow the individual profiles 2 to move with respect to one another without play.

the guide track 3. The spacer 5 is designed as an elastic or solid intermediate layer 6 which is arranged in the area of the radii of curvature 7 and 8 of the interlocking hook-shaped strips 9 and 10 of the individual profiles 2. As can be seen from Figure 1 in conjunction with the detailed views of Figures 1a and 1b, it can be seen that the intermediate layer 6 influences the two interlocking hook-shaped strips 9 and 10 in both the horizontal and vertical areas of the guide rail 3 in such a way that the hook-shaped curvatures 11 and 12 are pressed into one another so that no play can occur between the two hook-shaped strips 9 and 10.

According to the illustration in Figure 1a, the radii of curvature 7 and 8 of the individual profiles 2 open in the area of the curved path 4 of the guide rail 3, with the spacer element 5 remaining at the upper radius of curvature 8 of the profile strip 2. The front nose 13 of the intermediate layer 6 still engages between the radii of curvature 7 and 8 to such an extent that the play between the hook-shaped strips 9 and 10 is also kept small in the curved path 4 of the guide rail 3. This means that, thanks to the arranged intermediate layer 6, the roller shutter or sectional ceiling door 1 can be moved in the guide rail 3 in a controlled, quiet and smooth manner. This is achieved by the form-fitting connection of the individual profiles 2 to one another, because the hook-shaped curves 11 and 12 are held under pressure by the spacer element 5 while the door travels along the curved path 4.

According to a particularly advantageous development of the invention, shown in Figures 2 and 2a, the spacer element 5 is an elastically curved tab 14 which covers the joint area 15 at the front or rear, the tab 14 or leg spring (not shown) being fastened to the individual profiles 2. It goes without saying, in view of the enlarged detailed view of Figure 2a, that this curved tab 14 in particular influences the joint point, consisting of the hook-shaped strips 9 and 10, in such a way that the hook-shaped curvatures 11

and 12 of the strip 9 and 10 are pressed into each other and thus the tab 14 keeps the mutually positioned individual profiles 2 at a distance, so that a corresponding effect, as already explained in Figures 1, la and 1b, is also achieved.

According to a further advantageous development of the invention, according to a third embodiment, according to Figures 3 and 3a, it is proposed that the spacer element 5 is a helical spring 16 or leg spring (not shown) which is arranged between the end faces 17 and 18 of the individual profiles 2. In particular, in order to ensure that the roller door, ceiling-mounted sectional door 1 can be moved without play, the positive connection of the hook-shaped strips 9 and 10 is achieved by arranging the pressure-loaded spring 16 between the articulated individual profiles 2, which presses the two hook-shaped curves 11 and 12 of the strips 9 and 10 into one another, so that even with this design, a play-free movement of the roller door, ceiling-mounted sectional door 1 in the guide track 3 is ensured, in order to achieve an exceptionally quiet and smooth running of the door 1.
