Definitions

  • the present invention relates to a cover profile for covering insulating strips in composite profiles for window, door, or facade elements during coating of the composite profiles.
  • Thermally separated composite profiles for window, door or facade elements usually comprise one or more metal profiles to which insulating strips of thermally insulating materials such as PA6 or PA66 or the like are connected.
  • Such composite profiles are often coated, for example, by applying powder coating.
  • the coating is usually applied with the insulating strips already connected to the metal profile members. This is done in order to avoid possible damage to the coating during assembly, e.g., during rolling-in of the insulating strips. Further, it may also be done to avoid a decrease of the thermal insulation provided by the composite profile due to coated inner surfaces of the profile members. In addition, needed shear strength values can be obtained in this manner.
  • the profiles are usually handled in pieces of a length between, for example, 3 to 6 meters.
  • the insulating strips connecting the profile members are often formed of plastics such as PA66GF25 (PA66 with 25% glass fibre reinforcement) or similar materials. Due to several properties of polyamide and similar materials, it is difficult to achieve a smooth coating on the surface of the insulating strips.
  • the insulating strips are covered with a film or tape which is adhered to the insulating strips.
  • a liquid film is applied to the insulating strips before coating. These films are expensive and difficult to handle.
  • DE 10 2008 012 244 Al discloses a cover formed onto one side of an insulating strip. This cover is formed onto the insulating strip with a rated break point and can be removed from the insulating strip after coating by breaking off the cover at the rated break point.
  • WO 2008/119535 Al discloses a permanent cover that is attached to a ladder-shaped insulating strip via special clipping means for permanently covering the holes in the insulating strip.
  • An elastic cover profile that can be clipped onto the insulating strip allows an easy to handle and economic prevention of coating of an insulating strip of a composite profile. Due to its elasticity, such a cover can be easily clipped onto the insulating strip before coating and also can be easily removed after coating. Accordingly, the cover is reusable and may be used during plural coating processes of plural composite profiles.
  • the removal of the cover profile can be performed, for example, by pulling away one end of the cover profile covering the insulating profile of a coated composite profile.
  • the elastic cover profile may only require two or more clamping surfaces or contact portions defined on the insulating strip, the insulating strip itself may have an arbitrary geometry in the portion covered by the cover profile.
  • Such a cover profile can also be used for composite profiles with a single metal profile member such as a single aluminium shell as used in block windows/hidden sash-type windows.
  • the composite profile 100 shown in Fig. 1 extends in a longitudinal direction z and corresponds to a profile which may be used for block windows or hidden sash-type windows.
  • Fig. 1 shows a cross-section of the composite profile 100, wherein a cover profile 10 is attached to an insulating strip 12 connected to a metal profile member 14 by rolling-in in a known manner.
  • the metal profile member 14 may be an aluminium profile of the composite profile 100 for use in window, door, or facade elements.
  • the metal profile member 14 has a rolling-in groove 14g and a rolling-in hammer 14h for connecting the insulating strip 12 to the metal profile member 14 by rolling-in.
  • the metal profile member 14 has various surfaces to which a powder coating is to be applied.
  • Such coating may be applied in a known manner at temperatures in the range from, for example, 150°C to 230°C, and will not be described in detail.
  • the coating temperature may be, for example, in the range from 175°C to 225°, in particular, 180°C, 185°C, 190°C, 195°C, 200°C, 205°C, 210°C, 215°C, or 220°C.
  • Each of these individual temperature values may be either an upper or a lower limit of a corresponding temperature range for the coating.
  • the insulating strip 12 extends in the longitudinal direction z and may have an arbitrary geometry in the cross-section perpendicular to the longitudinal direction z. In the shown embodiment, it is a single-sided connected strip with functional elements such as a glazing bead groove 12g with a hook-shaped edge 12a, a guide channel 12r and protrusions 12p and 12t and a swallow tail-shaped edge 12s formed on the insulating strip 12 as a rolling-in projection 12s to be inserted in the groove 14g of the metal profile member 14.
  • the insulating strip 12 has a first longitudinal edge formed by the projection 12s and a second longitudinal edge formed by the edge 12a separated by a distance in a first transverse direction x perpendicular to the longitudinal direction z.
  • the insulating strip 12 is connected to the metal profile member 14 by pressing the rolling-in hammer 14h of the metal profile member 14 against the projection 12s to fit the same by rolling-in.
  • the insulating strip 12 protrudes from the metal profile member 14.
  • the composite profile 100 including the metal profile member 14 and the insulating strip 12 connected to the same generally have a length in the longitudinal direction z of several meters (usually 6m) before being cut to appropriate lengths during manufacturing and assembly of window, door, or facade elements.
  • the coating of the metal profile member 14 is performed with the insulating strip 12.
  • the cover profile 10 is attached to the insulating strip 12 before coating to prevent coating of the insulating strip or at least of the portion of the same that can be seen.
  • the cover profile 10 comprises a base portion 16 and two cover portions 18, 20 extending from the base portion 16.
  • the cover profile 10 has a substantially U-shaped cross-section in the cross-section (plane) perpendicular to the longitudinal direction z.
  • the cover portions 18, 20 form the legs of the U-shape and have clipping arms 18a, 20a that have free ends 18e, 20e and are resiliently connected to the base portion 16 via intermediate portions 18b and 20b.
  • the cover profile 10 is formed of a resilient material such as, for example, a polymer which may be glass reinforced.
  • the cover profile 10 is made of PA6 or PA66 or a compound containing the same.
  • the cover profile may comprise 15% to 50% glass fibres, preferably 25% glass fibres.
  • the material of the cover profile 10 is adapted to withstand the temperatures during powder coating of the composite profile 100. Such coating temperatures typically are in the range from 120°C to 250°C.
  • the U-shape of the cover profile 10, in combination with the resilient material forming the cover profile, allows for an elastic movement of the cover portions 18, 20 relative to the base portion 16 of the cover profile 10.
  • the cover profile 10 in a state in which the cover profile 10 is not attached to the insulating strip 12 (neutral state), the cover profile 10 has a shape with the free ends 18e, 20e of the cover portions 18, 20 separated by a first distance. This first distance is set such that it is smaller than the distance in the attached state of the cover profile shown in Fig. 1 .
  • the cover profile 10 is attached to the insulating strip 12 by clipping-on in the following manner.
  • the cover portions 18, 20 are displaced outwards and away from each other with respect to their neutral position such that a restoring force acts on the portions of the insulating strip 12 that are in contact with the legs 18, 20. Accordingly, the cover profile 10 is clamped onto the insulating strip 12 and does not come off unless a force which exceeds the forces applied to the insulating strip 12 by the cover portions 18, 20 is used to remove the cover profile 10.
  • engagement portions 22a, 22b are provided on the cover profile 10 for engaging with the functional elements such as a groove 12b between the protrusion 12p and the body of the insulating strip 12 or the hook-shaped edge (nose) 12a forming the second edge of the insulating strip 12.
  • the engagement portions 22a, 22b are resilient hooks. In the embodiment shown in Fig. 1 , the hook 22b is formed near the free end 18e of the cover portion 18, and the hook 22a is formed on the intermediate portion 20b. In this manner, the attachment of the cover profile 10 to the insulating strip 12 is more reliable, and a shifting or coming-off of the cover profile 10 during coating can be prevented even more reliably.
  • the cover profile 10 may be formed such that it only covers those parts of the insulating profile that are visible after assembly of the profile.
  • the side wall 12c of the insulating strip 12 opposite to the protrusion 12e is only partially covered by the cover portion 20, to an extent that allows the clamping of the cover profile 10 to the insulating strip 12 in the above-described manner.
  • this portion of the surface 12c is not visible after assembly, it is not necessary to completely cover the same during coating.
  • the cover profile 10 can be easily removed by pulling away the cover portion 20 at one end of the composite profile until the hook 22a is disengaged and lifting off the cover profile 10. This may be done manually or with the use of appropriate tools.
  • the cover profile 10 is configured such that, on the one hand, it allows for a secure clamping of the cover profile 10 to the insulating strip 12 and, on the other hand, it allows for an easy removal of the cover profile 10 after coating without using excessive force such that the cover profile 10 or the insulating strip 12 may be damaged.
  • the design of the cover profile 10 is formed to correspond to that of the insulating strip 12, enabling the clipping of the cover profile 10 to the insulating strip 12 without modifying the strip design.
  • the suitable functional elements of the strip such as gasket support, an operating rod groove, a screw channel, a glazing bead groove, or a gasket groove, may be used.
  • the cover profile 10 has been used to cover an insulating strip 12 attached to a single metal profile member 14 and protruding from the same.
  • Fig. 2 shows a composite profile 200 extending in the longitudinal direction z comprising a first metal profile member 214 and a second metal profile member 215.
  • the metal profile members 214, 215 are connected via two insulating strips, a first insulating strip 212 and a second insulating strip 213, by rolling-in in a known manner.
  • the second insulating strip 213 and its cover 210 are identical to the first insulating strip 212 and its cover 210, which will be described in detail with reference to Fig. 3 .
  • the first insulating strip 212 has two gasket supports 212g, 212h formed on a side 212d of a body 212c of the first insulating strip 212. On the opposite ends of the body 212c in a first transverse direction x, swallow tail-shaped edges 212s for a rolling-in connection to the metal profiles 214, 215 are provided.
  • the gasket supports 212h and 212g comprise one groove 212a, 212b each on their sides facing away from the respective other one of the gasket supports.
  • the cover profile 210 has a U-shaped cross-section in the cross-section (plane) perpendicular to the longitudinal direction z.
  • the cover profile 210 comprises a base portion 216 from which resilient cover portions formed as clipping arms 218, 220 with free ends 218e, 220e extend. Engagement portions 222a, 222b in the form of protrusions 222a, 222b are formed on the cover portions 218, 220.
  • the cover profile 210 may be made of the same materials as discussed above with respect to the cover profile 10 of Fig. 1 .
  • the cover profile 210 is clipped onto the insulating strip 212 by moving apart the cover portions 218, 220 and bringing the engagement portions 222a, 222b into engagement with the grooves 212a, 212b formed in the gasket supports 212g, 212h such that the free ends 218e, 220e are bent slightly outwards and rest on the insulating strip 12. Due to the resilient displacement of the cover portions 218, 220 relative to the base portion 216, the same are pressed against the gasket supports 212h, 212g protruding from the insulating strip 212 and serve to clamp the cover profile 210 to the insulating strip 212. In this manner, the same effects as described above in connection with the first embodiment can be obtained.
  • the cover profile 210 fully covers the side 212d of the insulating strip 12. After coating, the cover profile 210 may be removed from the insulating strip 212 by pulling off.
