Description
- The present invention relates to a profile assembly according to
claim 1 comprising a first profile and a second profile between which a thermally insulating spacer is received, particularly for use in window, door, veranda or outside wall applications, wherein the profile assembly is typically provided between two spaces in which different temperatures prevail. The invention further relates to a profile according toclaim 12 for use in such an assembly, to the use of an alley structure in such an assembly according toclaim 13 and to a method for mounting such an assembly according toclaim 14. -
DE 196 13 046 discloses an isolating element comprising a profile with a chamber and having an open side adapted to adjoin a first side wall of the spacer according to the preamble ofclaim 1 and claim 12. - The present invention has for its object to provide an improved profile assembly of the above stated type which provides better thermal insulation and is at the same time sufficiently strong. The invention more particularly has the object of providing a profile assembly with better thermally insulating properties than those of prior art profile assemblies of similar dimensions. According to advantageous embodiments, the height of the spacer can be easily varied.
- The profile assembly according to the invention is distinguished for this purpose in that the first profile is provided with a chamber with a first chamber wall, a second chamber wall and an open side between the first and the second chamber walls. The open side is intended to adjoin a first side wall of the insulating spacer. The first and the second chamber walls typically extend over the full length of the first profile. The first chamber wall is formed with a first clamping flange which typically extends over the full length of the first profile and is adapted to engage against the upper wall of the spacer. The first chamber wall is further formed with a second clamping flange which typically extends over the full length of the first profile and which is bendable against the first side wall of the spacer. The second chamber wall can be provided in similar manner with a first clamping flange which is adapted to engage against a lower wall of the spacer adjoining the first side wall and with a second clamping flange which is bendable against the first side wall of the spacer. Note however that it is also possible to provide this second chamber wall with a profiling into which the spacer can snap or slide. Although only the first profile has been detailed above, the skilled person will appreciate that the second profile can be formed in similar manner for the purpose of co-action with a second side wall of the insulating spacer.
- Note that the upper wall and lower wall do not have to be flat or horizontal walls, but refer to a wall adjoining the first side wall respectively at the top and at the bottom. Nor does the first side wall have to be a flat wall, and it can have corners. The skilled person will further appreciate that, in the mounted position of the assembly, the assembly can be situated in a tilted or reversed position in which the upper wall lies at the bottom or is oriented obliquely or vertically.
- Providing such a chamber in the first profile on the one hand and on the other a first clamping flange and a bendable second clamping flange intended for engagement against a first side wall of the insulating spacer allows the possibility of the insulating spacer being firmly anchored on the first profile by applying a bending means in the chamber for the purpose of bending the second clamping flange. Bending of the second clamping flange will here also ensure a firm fixing of the first clamping flange against the upper wall of the insulating spacer. The open side of the chamber adjoining the insulating spacer further provides for an additional insulation.
- According to an advantageous embodiment, the first and the second profile are manufactured from metal, preferably aluminium or an aluminium alloy. The first and second profiles are typically extrusion profiles or profiles formed with another technique, such as pultrusion profiles or roll forming.
- According to a preferred embodiment, the upper wall and the lower wall of the spacer are provided with a protruding ridge in the vicinity of the first side wall of the spacer. The first clamping flange of the first and second chamber walls then preferably have a modified hook shape such that this can engage behind the respective protruding ridges on the upper and lower walls of the spacer. The spacer can in this way be connected to the first profile, after which the second clamping flanges can be bent. The protruding ridges preferably extend over the full length of the spacer.
- According to a further developed embodiment, the first side wall of the spacer is provided close to the upper wall and close to the lower wall with a protruding ridge. The second clamping flanges of the first and second chamber walls are then preferably adapted to engage behind these protruding ridges. After bending thereof the second clamping flanges can in this way provide for a firm anchoring of the spacer.
- According to an advantageous embodiment, the spacer comprises an alley structure of a first thermally insulating material and a volume part of a second thermally insulating material. The first thermally insulating material is typically harder and/or stronger than the second thermally insulating material, wherein the first material is preferably such that it can comply with the applicable standards for metal profiles with a thermal barrier, for instance the European standard EN 14024. The properties of the material of the alley structure will be particularly relevant for the tensile strength test and the shear strength test described in EN 14024. Determined tests in EN 14024 are further performed in a temperature range between about -20 to 80 degrees Celsius, and the first and second materials must therefore preferably be sufficiently strong mechanically at these temperatures. Note that it is also possible for the spacer to be manufactured in one piece, for instance from a thermally insulating ceramic material or from HDPU. It is also possible to provide an alley structure alone without volume part. This can for instance be a multi-wall alley structure.
- The alley structure is preferably provided along at least a portion of the periphery of the volume part and is adapted to co-act with the first and second clamping flanges. The alley structure preferably extends over substantially the whole upper wall and lower wall of the spacer. In addition, the alley structure preferably also extends over at least a portion of the first and/or second side wall of the spacer, and in particular close to the upper wall and lower wall thereof. The volume part can in this way be positioned in a practical manner in the alley structure. Prior to bending of the clamping flange adhesive can further be applied to an outer side of the alley structure facing toward the clamping flange or to an inner side of the clamping flange. The parts of the alley structure located along the first and/or second side walls thus have the advantage of providing for a larger adhesive area.
- According to a preferred embodiment, the alley structure comprises an upper alley extending over the upper wall of the spacer and a lower alley extending over the lower wall of the spacer, wherein the volume part is received between the lower and the upper alley. This embodiment has the advantage that the height of the spacer can be easily changed by changing the height of the volume part. According to another variant, the alley structure consists of a tubular alley element in which the volume part is received.
- The alley structure is preferably manufactured from a thermoplastic copolymer, for instance ABS. The alley structure could however also be manufactured from a synthetic resin material, (glass fibre-filled) polyamide, polyurethane resins, a ceramic material, a rubber or a combination thereof. The alley structure can for instance be manufactured by extrusion or co-extrusion.
- The volume part is preferably manufactured from a hard foam material such as a PUR foam, a phenol foam, a PE foam, a PS foam or a PIR foam.
- According to an aspect of the present invention, the chamber is provided with a support means for supporting a mandrel to be moved through the chamber for the purpose of bending the or each second clamping flange.
- According to an aspect of the present invention, the chamber has a bottom between the first and the second chamber walls and the support means is formed by the bottom.

- According to an aspect of the present invention, the first and/or the second clamping flange is provided with an adhesive layer on an inner side intended to engage against the spacer; and/or the spacer is provided with an adhesive layer on an outer side intended to engage against the first and/or second clamping flange.
- The present invention further relates to a profile according to
claim 12 for use in an embodiment of a profile assembly as described above. This profile can have one or more of the measures described above for the first profile. According toclaim 12 the invention also relates to the use of an alley structure according toclaim 13 in an embodiment of a profile assembly as described above. The alley structure can have one or more of the above described measures. - Finally, the invention relates to a method for mounting an insulating spacer between a first and a second profile according to
claim 14. The spacer is placed in the longitudinal direction between the first and the second profile. The first profile is provided with a chamber with a first and second chamber wall extending in the longitudinal direction thereof and an open side between the first and second chamber walls. The first profile is placed with its open side against the first side wall of the spacer. The first chamber wall is formed with a first clamping flange arranged over the upper wall of the spacer. The first chamber wall is further formed with a second clamping flange which is bent against the first side wall of the spacer. In similar manner the second chamber wall can be formed with a first and a second clamping flange, wherein the first clamping flange is arranged over the lower wall of the spacer and the second clamping flange is also bent against the first side wall of the spacer. The connection of the second profile to the spacer can take place in similar manner on the second side wall of the spacer. - According to an advantageous embodiment of the method according to the invention, bending of the second clamping flanges is performed by moving a mandrel through the chamber of the first profile. The second clamping flanges of the second profile can be bent in similar manner by moving a mandrel through the chamber of the second profile.
