Abstract

The broad sides of the bars (1) are adjacent in the direction of movement. Their longitudinal edges interlink by round hook-shaped sectioned parts running at right angles to the casing's direction of travel. A sealing strip (10) runs along the longitudinal edges at the interlinking parts and is attached to one longitudinal edge. On the other longitudinal edge, at least when the casing is closed, the sealing strip closes the slot needed for the interlinking movement. The sealing strip consists of a folded metal strip (2) joined along its longitudinal edges.

Description

The invention relates to a roller door according to the preamble of claim 1. Such a roller door is from GB-A-2 209 789 known, discussed in more detail below becomes.

Roller doors are known from the prior art. You exist from a multitude of one another in the closing direction arranged and articulated together Bars, which are preferably made of metal. Of the roll armor thus formed is when opening such Rolling gates wound up on a winding shaft. For Guiding the roll armor in the side frame area of one Wall openings are generally substantially U-shaped trained guide rails provided.

In the known from GB-A-2 209 789 mentioned at the outset The roller shutter grips the bars for an articulated connection by means of rectangular hooks in cross section, rectangular to the direction of movement of the tank running longitudinal edge training articulated into each other.

This is different from sectional gates, e.g. at the gate known from US-A-4,368,772, see which are usually adjacent to wide-area panels on the inside by means of separate hinge connections are hinged together.

Compared to training with separate hinges the roller doors known from GB-A-2 209 789 the advantages easier training and assembly and less Weight. In addition, due to the fact that the Interlocking rods with their longitudinal edge configurations, no continuous and accordingly drafty gap between the same more. The rods of the known from GB-A-2 209 789 Roller shutters are made of metal and outside inside made of plastic. The connection point between neighboring bars is also by a Part of the outer surface of one of the adjacent rods covered nose-shaped area. Next is one Sealing strip for sealing the transition area between provided the bars. The sealing strip is about to to protect against environmental influences and to ensure a continuous To create one on the inside edge of one adjacent rods set and engages the inner Sealing the area of the other rod. Even though such roller doors have proven in the prior art, so causes the closing and opening of such Roller shutters right due to metal parts lying on top of each other high noise emissions. In addition, the manufacture of the made of a plastic inner part and a metal outer part existing rods are relatively complex and expensive.

Based on the prior art according to GB-A-2 209 789 the invention is therefore based on the object of a roller door with the features of the preamble of the attached Claim 1 to create that from simple and inexpensive producible rods that have a sound-reducing Seal a barrel especially in the closed position Enable roller shutters.

This task is accomplished by a roller door with the characteristics of claim 1 solved.

In the roller door according to the invention is therefore the sealing strip between one part of the outside of one of the adjacent rod-forming nose-shaped section and the longitudinal edge region of the other rod.

A roller door designed according to the invention accordingly has a sealing strip on, which is arranged in the transition area of two adjacent bars is that this transition area is sealed in the closed position of the tank is. On the other hand, the sealing strip is used for sound insulation in particular made of metal, namely for example sheet steel and / or aluminum Roll armored vehicles, because the sealing strips meet directly two adjacent metal bars at least in this area is avoided. Furthermore, through the weather strip Vibration movements of adjacent rods of the roller shutter are damped, so that the resulting noise can also be reduced. By the arrangement of the weather strip can therefore be the rods of the tank in easier and inexpensively made entirely of metal, especially sheet steel are manufactured.

Advantageous embodiments of the invention are the subject of subclaims.

So it is further provided that in the overlapping area of the interlocking longitudinal edge designs a sealing strip extending along this is provided, which on a the longitudinal edge formations is defined and at least in the other When the tank is closed, the slot required for the articulation of the joint closing attacks.

A simple installation of the sealing strip on a rod takes place after a Another feature of the invention in that the sealing strip on the Rods is sprayed on. Here, the sealing strip is streaked on the Rods applied. The sealing strip preferably consists of a hardening Foam that is still permanently elastic even when cross-linked. When applying the sealing strip, it is pasty and self-adhesive, so that additional adhesives or other fasteners are not necessary.

According to a further advantageous feature of the invention it is provided that the sealing strip in one, preferably with the outer contour of the sealing strip corresponding, recess is arranged. This is advantageous Recess groove-shaped, so that the sealing strip in particular a plane running parallel to the broad surfaces of the bars against the stress is fixed by the hinges. This is primarily through this enlargement of the contact area between the sealing strip and rod is achieved.

This results in a particularly simple construction of the roller door according to the invention created each rod from a folded one and at its ends together connected sheet metal strip. Alternatively, it can be provided that each rod consists of two metal strips that are folded and at their ends are folded together.

A more extensive sound insulation and thermal insulation is after a achieved a further advantageous feature of the invention in that the rods are foamed are, the foaming preferably consists of polyurethane. The foaming the rods not only contribute to reducing the noise emission when moving the roller shutter, but also to increase the stability of the Armored personnel carrier at.

The sealing strip is preferably circular in cross section, so that the largest possible sealing surface is achieved. Furthermore, this has Design the advantage that the neighboring bars in low-friction as possible Are sealed against each other.

Alternatively, it can also be provided that the sealing strip in cross section rectangular, preferably square.

In a preferred embodiment, the hook-shaped ends are at least what the Execution from a sheet metal strip by folding in the direction of The outer surface of the rod is protruding. Basically, such is Canting to the outer surface for both ends of the hook-shaped longitudinal edge areas, folded or folded, provided.

In a particularly preferred embodiment, the sealing strip is in the transition area between the round hook-shaped longitudinal edge formation and the after outside facing rod surface arranged. This area is closed Rolled armor from the nose-shaped section of the neighboring one Covered rod that engages sealingly on the weather strip. This creates a cavity between the articulation and the seal, which is mainly the Insulation serves.

In Figure 1, a rod 1 is shown in side view, which consists of exactly one Sheet metal strip 2, which is folded in the form of rods 1 and in the area of his one end 3 is connected to its longitudinal edges. The rod 1 has one in substantially flat outer surface 4 and one of the outer surface 4 opposite arranged and arcuate-shaped inner surface 5.

In the area of the end 3, the rod 1 is formed like a round hook. On the opposite End 6 of the rod 1 is a similar longitudinal edge formation in Form of a substantially circular in cross section and in one area open locking device 7 is formed. The protrude through bend and the roughly connected by folding longitudinal edges towards the outer surface 4 of rod 1.

As can be seen from FIG. 2, a plurality of rods 1 form a roll armor 8, the bars 1 with their broad sides in succession in the direction of movement are hinged together. To do this, the round hook-shaped end 3 of a rod engages 1 in the locking device 7 of the adjacent rod, so that the neighboring Rods 1 about their connecting axis running in the longitudinal direction of the rods 1 are articulated together. The junction of the round hook-shaped End 3 of a rod 1 with the locking device 7 of the adjacent one Rod 1 is covered by a nose-shaped section 9, the nose-shaped section 9 is part of the outer surface 4 of the adjacent rod 1. Between the outside area of the round hook-shaped end 3 and Rod 1 and the inside of the nose-shaped section 9 of the adjacent Rod 1, a weather strip 10 is arranged. In the example according to FIG. 2 the end 3 is shaped somewhat differently than in the example according to FIG. 1, namely with respect to the associated connected long sides to Rod interior directed and only partially facing the outer surface 4 of the rod.

The sealing strip 10 is made of an elastic foam that on the Outer surface of the round hook-shaped end 3 of each rod 1 is sprayed on and runs in the longitudinal direction of each rod 1. In the illustrated in Figure 1 In one embodiment, the sealing strip 10 has a circular, in Figure 2 has a rectangular cross section.

FIGS. 3 to 7 show a second embodiment of the invention Roller doors, in particular the rods 11 shown. The rods 11 differ of the rods 1 shown in Figures 1 and 2 on the one hand in that each Rod 11 consists of two individual sheet metal strips 12 and 13, which in the form of Rod parts folded and in the region of a round hook-shaped first end 14 and a locking device 15 are folded together.

The sheet metal strip 12 forms the outside of the rod 11, the Sheet metal strip 12 at least in a partial area 16 by cold forming Micro-profiling is corrugated, as in the example according to Figure 1 is the case. The sheet metal strip 12 is essentially flat. The sheet metal strip 13, on the other hand, is designed in the shape of a circular arc.

As shown in FIGS. 4 to 7 in particular, each rod 11 can be foamed be, the foam 17 consists of polyurethane.

In the area of the round hook-shaped end 14, which in the same way with the Locking device 15 cooperates, as is shown in FIGS. 1 and 2 in FIG Described with respect to the round hook-shaped end 3 and the locking device 7 is in the sheet metal strip 12 a extending in the longitudinal direction of the rods 11 Groove-shaped recess 18 with a circular cross-section. In this recess 18, a sealing strip 19 is inserted, which at closed roll armor 20 on a nose-shaped section 21 of the adjacent Rod 11 rests sealingly. The nose-shaped section 21 covers this the junction of two adjacent rods 11 in the area of the round hook End 14 of a rod 11 and the locking device 15 of the adjacent rods 11. This creates a substantially smooth surface appearance the roll armor 20 consisting of a plurality of rods 11 achieved.

The relative position of two adjacent bars in the so-called zero position of the Tanks 20, i.e. with the roller shutter closed is shown in Figure 5. The In contrast, FIGS. 6 and 7 show the relative position of two neighboring ones Rods 11 to each other with a negative and positive entry angle. Here is too recognize (Figure 6) that with a negative entry angle of the nose-shaped section 21 engages over the sealing strip 19 without permanently deforming it, whereby the nose-shaped section 21 with a negative entry angle on a surface a paragraph 22 of the sheet metal strip 12 comes to rest.

In the case of the positive entry angle, as indicated in FIG. 7, the nose-shaped section 21 from the sealing strip 19.

As can be clearly seen, the sealing strip 19 has the in the Figures 3 to 7 embodiment shown a round cross section. Of the Sealing strip 19 consists of solid material. But it is also conceivable that the Sealing strip 19 is hollow cylindrical.
