In order to minimize damage caused by collision or exclude it is known in the case of roller shutters according to the prior art, to provide a division of the door curtain stiffening and leading end strip. In addition, as with a roller door after the DE 40 07 280 C2 , The parts of the end strip, in particular their end parts made of a material of high elasticity, so that in the event of a collision when exceeding a predetermined transverse force, the end parts emerge under elastic deformation of the guides.

In order to bring the drawn-out edge strips of the door curtain and the end parts of the end strip in their desired position, the door curtain must be pulled together with closing bar upwards, in a position above the ends of the guides so that the edge strips can be threaded back into the guides. During this Moving upward, the edge strips of the door curtain or lateral parts of the finishing strip of the door curtain grind on the outside of the goal posts or on the soffits of the wall opening. This additional load is present in the event of hair lifting by the mass of the end bar and also in the case of a curtain lift with tensioning cables. The object of the invention is to provide a rolling shutter with simple means and low structural complexity, which does not have the aforementioned disadvantages or in which the disadvantages are substantially reduced.

The object is achieved by a roller shutter with the features of claim 1 or by a gate column for a roller shutter with the features of claim 6; the respective subordinate claims disclose embodiments of the invention rolling shutter or a novel gate column for a roller door of this genus.

The reference numerals drawn in the figures have the same meaning each, even if they are not explicitly mentioned in the description of the embodiments for each figure.

The new roller door 4 according to the invention is in the FIG. 1 shown in a perspective view. On a floor 3 is a portion of a wall 1 with a wall opening 2. On one side of the wall 1 is a roller shutter 4, here in self-supporting design, arranged at the wall opening 2. Sideways of the soffits of the wall opening 2 are the torso columns 10 and 11 of the roll-up door 4. Above the wall opening 2, a winding shaft 12 in bearings 14, 15 is arranged rotatably and drivable.

The drive 13 here consists of a motor, a transmission and a control unit. The control unit together with its operating element is arranged at normal working height in one of the door columns 10 and 11, respectively. A duplicate of the control unit is then still on the other side of the wall opening 2 next to selbiger 2.

On the winding shaft 12 of the flexible door curtain 5 of the roll-up door 4 is stored. By rotating the winding shaft 12 in accordance with the specification of the control unit, the door curtain 5 is moved between a first end position "door open" and a second end position "door closed". At rest and during movement of the door curtain 5 whose edge strips 6, 7 are each guided in a guide slot 16 of each column column 10, 11.

At the lower transverse side of the door curtain 5, a cover strip 8 is provided.

The horizontal distance between the respective front plane FE of the gate columns 10 and 11 corresponds approximately to the length L between the sides 8a, 8b of the end strip 8, wherein on both sides of the end strip 8 to the respective front plane FE through a gap is formed, so that upon movement of the door curtain 5 and thus the end strip 8 no jamming of the end strip 8 between the columns 10, 11 takes place. The distance between the gate columns 10, 11 is also chosen so that the inside width LW of the wall opening / door opening 2 can be fully utilized. For one end position "gate open" the door curtain 5 is raised so far and rolled up on the winding shaft until the lower edge of the end strip 8 above the clear height LH of the wall opening / gate opening 2 is.

In the FIG. 2 is the roller shutter 4 after FIG. 1 shown in a cross section at the section line AA. The illustration is a partial cross-section, this is sufficient for explanation, since the two gate columns 10, 11 and the environment around selbige same. The torso column 10 at a distance opposite torso column 11 is executed only a mirror image, so that the explanations to the features of the invention can be made on a partial section.

The gate column 10 shown here has a front 18, a back 19, a free side 20 and a wall side 21, with the gate column 10 is disposed on the wall 1 near the wall opening 2 so that the formed by the front 18 front plane FE of Gate column 10 with a small distance L1 sideways the reveal of the wall opening 2 is. In the front side 18 of the door pillar 10, a guide slot 16 is provided for guiding the edge strips 6, 7 of the door curtain 5 in a guide plane BE.

Starting from the front plane FE of the front 18 of the gate column 10, vertically directed relaxation channels 24 are provided here laterally of the guide slot 16 in the direction of the body of the column 10, respectively for freely receiving one of the edge strips 6 or 7 or sections thereof after a said crash So, to relax the tensioned during the crash Torbehanges, as well as to lead and guide them when they return to their normal position.

On the wall side, the at least one guide channel 24 is formed with a wall section 1 a of the wall 1 and an inclined surface 18 d of the body of the column 10. The relaxation trough 24 arranged on the other side of the guide slot 16 is defined at least by a bevel 18c of the body of the pillar column 10 extending from the front 18 and towards the free side 20, so that from the front plane FE and from the end strip 8 of the door curtain 5 facing away, which is formed at the gate column 10 required clearance, to the further details will be explained later.

The both sides of the guide slot 16 to the guide slot 16 facing portions of the front 18, form of the front plane FE from the body receding guide surfaces 18a and 18b, which define a guide funnel 23. These guide surfaces 18a and 18b each have a guide strip 17 in the region of their smallest distance from one another. Preferably, each guide strip 17 is formed by bending the end sections of the guide surface 18a or 18b. Between the mutually spaced guide rails 17 is the guide slot 16, which generates by this configuration, compared to known roller doors, a lower friction in the movement of the door curtain 5 at the edge strips 6 and 7 respectively.

The transition from the sliding surface 18 c or 18 d to the guide surface 18 a and 18 b is made in the embodiment shown by bending in the relevant component of the gate column 10. This fold is also such that dome 22, so in each case a dome 22, are formed, which cause a gentle sliding of the edge strips 6 and 7 in the process "reversing" or upon retrieval in the guide slot 16 in a crash.

In the FIG. 2a is the roller door after FIG. 2 shown in a situation after a crash on the curtain 5. By this crash the door curtain 5 has been pressed together with end strip 8 from the guide level BE in the direction of wall opening 2 from the guides 16. The tensioning cable 9 provided for this door to the door tension tension, which engages usually at the respective edge region of the end strip 8, is also pulled out of the guide slot in such a crash with a partial section. With the guide surface 8a and 8b of the guide funnel 23 together with the dome 22 a gentle, friction-moderate guidance of this section of the tensioning cable 9 is also guaranteed.

Because of the present invention and preferably immediately adjacent to the guide slot 16 provided relaxation channel 24 at each gate column 10, 11 there is no jamming after a crash of the door curtain 5, in particular its edge strips 6, 7 between the front 18 of the gate column 10, 11 and between the end strip 8 and the reveal of the wall opening 2. The edge strips 6 and 7 are in the contour of the respective expansion channel 24th given limits freely movable. There is also no bending and tension of the side edges 6, 7 of the door curtain 5 between the soffits of the wall / door opening 2, as is otherwise the case in the prior art.

Such a situation according to the prior art is in the FIGS. 6 , especially in FIGS. 6b and 6c shown. With the novel roller shutter 4 according to the invention, such additional loading of the door curtain 5 and its parts, which cause increased wear or even damage to the door curtain 5 is avoided with little effort.

In the FIG. 3 and 3a the roller door 4 according to the invention is also shown in a partial cross-section. Here, the roller shutter 4 is installed with its door column 10 in an existing next to the reveal of the wall opening 2 wall niche 1 b. This illustration is intended to make it clear that the new roller shutter door can be used for closing and opening wall openings / door openings of the most varied types. The situation shown in FIG. 3 is similar to the situation FIG. 2 and the situation in FIG. 3a according to the situation FIG. 2a so that no repetitions are made here. The reference numbers used in principle throughout the description same meaning, even if they are not explicitly mentioned in the description of the individual figures.

In the FIG. 4 and 4a is a Torsäule 10 'shown for subsequent installation on already in operation shutters in a partial cross-section.

The two states shown correspond to those in the Figures 2 or 2 states shown and described, namely the "normal operation" and the "reversing after a crash".

This gate column 10 'is at least formed by two legs arranged substantially at right angles to each other, a front 18 and a wall side 21. Starting from the front plane FE of the front 18, the outer wall sections of the front 18 escape, so that on both sides of a guide slot 16 in the body of the column 10 'each a relaxation channel 24 is formed. This gate column 10 'is placed and fixed with its wall side 21 on a wall at the same location next to the wall opening for replacement with the already in operation gate column. As already mentioned above, the opposite gate column is constructed in mirror image, it is not shown here because it is similar.

In the FIG. 4a is also a situation after a crash shown. The pulled out of the guide slot 16 edge strip 6 of the door curtain 5 is located substantially in the relaxation channel 24 and is, within said limits, free to move the process "reversing". In this position, the door curtain 5, without being subjected to damage by strong deflection and friction on edges and wall surfaces, can be moved upwards to a position in which the threading into its desired position, ie in the guide plane BE occurs; this is in the extreme case a position above the end of the gate columns.

In the following FIGS. 5a to 5e Further profile cross sections are shown, which can be used in this gate column 10 'and also in the gate columns 10 and 11 of the roller door 4 described above. Which profile / profile cross-section is used depends on the specific installation conditions and task of the respective application. Such conditions can be, for example, production costs / material costs, special stability conditions or spatial conditions.

The invention is not limited to the illustrated and described embodiment, but in particular also includes variants that can be formed by combining features or elements described in connection with the present invention. Furthermore, individual features or modes of operation described in conjunction with the figures can in themselves constitute an independent invention. The Applicant thus reserves the right, so far only in the description, in particular in conjunction with the figures disclosed features of claim significant to the invention. The claims filed with the application are therefore merely formulation proposals without prejudice to the achievement of the patent protection contained in the present application.
