Definitions

  • the invention relates to a dimensionally stabilized roller shutter rod, which consists of an aluminum strip roll-formed into a hollow body profile, and a method for producing such a dimensionally stabilized roller shutter rod.
  • a dimensionally stabilized roller shutter rod which has a reinforcing part in the central axis of the hollow body profile.
  • This reinforcement part consists of a PVC insert body which can be additionally reinforced by a metal core during the production by means of an extrusion process.
  • the finished roller shutter rod made of plastic shows disadvantages when weathering, especially when exposed to sunlight and low temperatures. Under these conditions, the plastic may become brittle and, after prolonged exposure, the outer layer may become discolored. In addition, the manufacturing method is very time consuming and expensive.
  • a roller shutter rod is known from German utility model G 8907445, which is roll-formed with the formation of connection areas and walls from an aluminum band coated with plastic.
  • the coatings of the walls are formed with different layer weights, so that the weight distribution is asymmetrical damping of the vibrations of the hollow body profile and thus a reduction in the noise emission can be achieved.
  • roller shutter slat is described in European patent application EP 03 65 908, which is roll-formed from a aluminum strip coated on one side to form a hollow body profile, a double-layer plastic layer being formed in the area of the connection areas, which ensures that the sound emitted by the roller shutter is damped arises because the acoustic decoupling of the aluminum surfaces prevents sound transmission between them.
  • the invention has for its object to provide a dimensionally stabilized roller shutter bar, the bending stiffness and durability are improved without the sound-absorbing properties are reduced. that the object of the invention is also to provide a manufacturing process for such a dimensionally stabilized roller shutter bar with high flexural strength and durability.
  • the durability of the form-stabilized roller shutter rod results from the fact that it is made entirely of durable aluminum at the places exposed to the weather.
  • the improved bending stiffness stems from the fact that in the area of the at least two aluminum strip layers it is no longer possible to shift them relative to one another, in particular when subjected to torsional stress. This has a particular effect on temperature stresses, such as those that occur when the roller shutter rod is exposed to direct sunlight.
  • the twists occurring in known roller shutter slats, in which the ends of the hollow body profile running in guides rotate about the longitudinal central axis, are avoided in the roller shutter slat according to the invention.
  • connection of the at least two aluminum strip layers is formed by a plastic layer which is designed as a hot-melt adhesive layer in the region of the contact point.
  • the material connection in the area of the adhesive layer creates the desired non-positive connection.
  • the hot-melt adhesive layer is applied to edge areas of the aluminum strip which, after roll forming, face one another in the double-layered strip areas.
  • the non-positive connection can also be formed by a welded connection.
  • non-positive connection of the at least two aluminum strip layers is formed by a rivet, screw or clinch connection, a good and, if desired, detachable mechanical fixation can be achieved.
  • connection areas are preferably provided in one of the connection areas, both connection areas also being able to be fixed accordingly.
  • the at least two aluminum strip layers are formed by the inner wall and the outer wall, which are brought together at a contact point to form a non-positive connection. It is thereby achieved that not only the surfaces in the connection area are mechanically fixed, but the central area of the hollow body profile is solidified at at least one point to increase the bending stiffness. This also changes the resonance behavior of the roller shutter slat and thus improves sound absorption.
  • the fixing between the inner wall and outer wall is preferably achieved by deforming the inner wall in the direction of the outer wall, so that there is a smaller bending radius in the area of the contact point with respect to the inner wall than in the case of the outer wall.
  • the form-stabilized roller shutter slat according to the invention is preferably roll-formed from aluminum strip material which has a thickness between 0.15 and 0.8 mm.
  • the method according to the invention for producing a dimensionally stabilized roller shutter rod includes the method steps that an aluminum band coated on one side with a plastic is roll-formed to form a double-layer connection area and an inner wall and an outer wall to form a hollow body profile, and that a non-positive connection between at least two aluminum band layers is formed.
  • the plastic preferably consists of an adhesive medium, the aluminum strip layers formed into the hollow body profile being held under pressure in at least one of the two connection regions until a non-positive connection is produced.
  • the plastic layer consists of a hot-melt adhesive and the aluminum strip formed into the hollow body profile is glued or welded after heating in the area of the double-layer connection areas, the material connection of the adhesive connection results in a particularly high bending stiffness.
  • roller shutter slat according to the invention, consisting of the hollow body profile 1 and two connecting ends 2, 3 with a corresponding hook and eye area 4, 5.
  • the roller shutter rod has been produced by roll forming from an aluminum strip 6 which is coated with an adhesive medium 7 on the entire inside of the hollow body profile and also between the connection ends.
  • the adhesive medium 7 can be carried out by extrusion coating, by applying a liquid or by lamination using a polymer film. In roll forming, the adhesive medium is pressed against one another at the connection ends, thereby producing an intimate contact between the adhesive medium and the aluminum strip. By exposure to heat, this contact can be formed into a non-positive connection that can withstand high mechanical loads.
  • a polyethylene copolymer has proven itself for coating the aluminum strips. It is advantageous if the copolymer is provided with sound-absorbing pigments which are either applied to the aluminum strip in the liquid phase during extrusion or are already present in the finished laminating medium. The soundproofing properties are greatly improved by the full-surface coating of the hollow profile interior. The coating can also be done with a polypropylene film.
  • the adhesive medium is limited to the contact points 8,9,10 at the connection ends.
  • This variant represents a simplified embodiment compared to the full-area coating shown in FIG. 1, but which shows equivalent results in terms of dimensional stability.
  • a mechanical connection is shown at the connection ends of the roller shutter bar.
  • the exemplary embodiment are in the hook area 11 and Several rivets 11a-d and 12a-e are shown in the eyelet region 12.
  • FIG. 4 now shows a non-positive connection in the form of an adhesive bond 15 between the outer wall 13 and the inner wall 14 of the roller shutter rod.
  • the aluminum strip in the central region of the inner wall 14 was deformed inwards to such an extent that it forms a contact point with the outer wall 13.
  • a previously applied adhesion promoter can bring about the positive locking.
  • the brackets can follow the points at one or more points on the inner and outer walls or also continuously in the form of a line in the direction of the longitudinal center axis.
  • adhesive bonds 16, 17, 17 a are also provided at the connection ends. All bonds can be made in cold or warm condition. For higher strength requirements, however, it has proven to be advantageous to non-positively connect the aluminum strip regions provided with an adhesive medium under the action of heat. When the adhesive media are heated, the temperatures are above approximately 100 ° C. and preferably in the range from 150 to 200 ° C. The hot-melt adhesive is activated and the strength of the hollow body profile corresponds to that of a profile of the same dimension that is foamed with PU foam.
  • the heating can be carried out by commercially available means, e.g. by infrared or induction heating elements which are attached at a suitable point during roll forming of the roller shutter rod according to the invention.
  • the finished product must then be specifically cooled, for example by blowing with air.
  • roller shutter slats according to the invention can withstand solar radiation at temperatures of up to 80 ° C. All suitable resins, acrylates and hot melt adhesives such as polyamides can be used as adhesives between plastic and metal.
  • contact points at various points of the hollow body profile are also possible in the central region.
  • the contact points are produced in that the aluminum strip, which originally runs in parallel, is deformed between the connection ends of the roller shutter rod in the central region of the hollow body profile.
  • the inner wall 14 of the hollow body profile 18 is preferably deformed such that a contact point 15 with the outer wall 13 is created.
  • the outer wall 13 e.g. are deformed in a bead shape, the bead base forming a contact point with the inner wall 14 of the hollow body profile 18.
  • both walls 13, 14 can also be deformed at the same time if this is expedient for reasons of strength or to increase stability.
  • the non-positive connection that can be achieved with the adhesive bond in the cold or warm state can also be achieved by other thermal processes such as welding or soldering or also by cold connection processes such as pressure or friction welding.
  • connection processes such as rivets, screws, clipping and other pressure forming processes can also be used. It is crucial that a frictional, temperature-stable connection is created, which also withstands an oscillating load, such as can occur under the influence of wind forces.
  • plastics and in particular hot-melt adhesive can be used in the production of the non-positive connection. These are welded under the influence of heat (plastics) or glued (hot melt adhesive).
  • hot melt adhesive In addition to the copolymers mentioned in the description, such as polyethylene, polypropylene film can also be used.
