Definitions

  • the invention relates to a dimensionally stabilized roller shutter slat, which consists of a one side coated with plastic and with the coated side facing inwards to form a hollow body profile with connecting ends of roll-formed aluminum strip, the aluminum strip being formed at least at the connecting ends with a double layer with an intermediate plastic layer, and a method for producing such dimensionally stabilized roller shutter bar.
  • a form-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.
  • roller shutter slat is described in European patent application EP-A-03 65 908, which is roll-formed from an aluminum band 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 damping of the Shutters of emitted sound are created because the acoustic decoupling of the aluminum surfaces prevents sound transmission between them.
  • EP-A-03 65 908 is roll-formed from an aluminum band 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 damping of the Shutters of emitted sound are created because the acoustic decoupling of the aluminum surfaces prevents sound transmission between them.
  • EP-A-03 65 908 is roll-formed from an aluminum band 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 damping of the Shutters of emitted sound are created because the
  • 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.
  • the object of the invention is also to provide a manufacturing method for such a dimensionally stabilized roller shutter bar with high bending stiffness and durability.
  • the object is achieved in the case of a dimensionally stabilized roller shutter slat of the type mentioned at the outset in that, in the region of the double-layer aluminum strip, the strip layers are at least partially bonded to one another via the plastic layer formed as an adhesive medium and hardened by the action of heat.
  • 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.
  • 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.
  • gluing with a plastic film is sufficient, which is either applied to the aluminum strip before the roll forming or separately introduced into the forming process before or after the roll former. If the bonding is to be limited to the edge areas, it is sufficient if a correspondingly narrow plastic tape with the hot-melt adhesive layer runs in on both sides of the roller shutter rod.
  • the integral connection can also be formed by a welded connection.
  • connection is 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 the integral 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 the double-layer aluminum strip surfaces in the area of the connection ends are at least partially bonded to one another by the plastic layer designed as an adhesive medium being solidified by the action of heat.
  • the invention therefore provides that where at least two aluminum strip layers are adjacent, these are fixed against each other by a material connection, so that no more movement of the belt layers in the area of their contact point is possible. This results in the desired solidification of the roller shutter bar
  • the plastic preferably consists of an adhesive medium, the aluminum strip layers formed to form the hollow body profile being held under pressure in at least one of the two connection regions until a cohesive 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 region of the double-layer connection areas, the material connection of the adhesive connection results in a particularly high bending stiffness.
  • a practical procedure results from the fact that the bonding or welding takes place after the roll forming of the hollow body profile.
  • the hot-melt adhesive is heated during roll forming by heating the aluminum strip.
  • 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 is formed into a cohesive 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. Due to the full area Coating the hollow profile interior, the sound-absorbing properties are greatly improved.
  • 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.
  • Figure 3 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 integral cohesion.
  • the brackets can follow the point at one or more points of the inner and outer wall or also continuously in the form of a line in the direction of the longitudinal axis.
  • adhesive bonds 16, 17, 17 a are also provided at the connection ends.
  • bonds can be made in a cold or warm state.
  • the temperatures are when the Adhesive media above approx. 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 which 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, e.g. 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 e.g. Use polyamides.
  • contact points are also possible in the central region at various points on the hollow body profile.
  • the contact points are produced in that the originally parallel aluminum strip is deformed between the connecting 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 in such a way that a contact point 15 with the outer wall 13 is created.
  • the outer wall 13 can also be deformed, for example, in a bead-like manner, the bead bottom forming a contact point with the inner wall 14 of the hollow body profile 18. Beyond that too Deform both walls 13, 14 at the same time if this is expedient for reasons of strength or to increase stability.
  • plastics and in particular hot-melt adhesive can be used in the production of the integral 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.
