    • Patent Number:
      6,035,600
    • Appl. No:
      08/922,199
    • Application Filed:
      September 02, 1997
    • Abstract:
      A heat-insulated composite section for doors, windows and facades, includes a plurality of metal rail sections so connected as to form a frame, at least one insulating rod arranged between the rail sections and having longitudinal edges secured to the metal sections, and a compensation structure provided in a longitudinal connection zone between interconnected components for eliminating a flexure of the rail sections when subject to uneven temperature rise. The compensation structure effects a slight resistance to longitudinal displacement, or resistance to longitudinal displacement that approaches zero, or is formed by a sliding-type guidance.

    • Claim:
      What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims
    • Claim:
      1. A heat-insulated composite section for doors, windows and facades, comprising
    • Claim:
      a plurality of metal rail sections so connected as to form a frame;
    • Claim:
      at least one insulating rod arranged between the rail sections and having longitudinal edges secured to the rail sections; and
    • Claim:
      compensation means provided in a longitudinal connection zone between interconnected components for eliminating a flexure of the rail sections when subject to uneven temperature rise
    • Claim:
      wherein the insulating rod is of two-part configuration having a first rod member connected with one rail section in a manner to resist a longitudinal displacement, and a second rod member connected with another rail section in a manner to resist a longitudinal displacement, with the first and second rod members being connected at a central location by the compensation means in the form of a sliding-type guidance.
    • Claim:
      2. The composite section of claim 1 wherein the insulating rod is made of plastic material.
    • Claim:
      3. The composite section of claim 1 wherein the compensation means effects a slight resistance to longitudinal displacement in the longitudinal connection zone.
    • Claim:
      4. The composite section of claim 1 wherein the compensation means effects a resistance to longitudinal displacement in the longitudinal connection zone that approaches zero.
    • Claim:
      5. The composite section of claim 1 wherein the sliding-type guidance is effected by guide surfaces formed by one rail section in the longitudinal connection zone and oriented substantially perpendicular to a center axis of the insulating rod.
    • Claim:
      6. The composite section of claim 1 wherein the sliding-type guidance is effected by guide surfaces formed by one rail section in the longitudinal connection zone and so oriented as to deviate from a perpendicular disposition with regard to a center axis of the insulating rod by .+-.20.degree..
    • Claim:
      7. The composite section of claim 1 wherein the sliding-type guidance is effected by a groove formed in one rail section and a guide arm formed on the insulating rod and received with play in the groove.
    • Claim:
      8. The composite section of claim 7 wherein the one rail section has opposing border webs facing the insulating rod to define the groove in the form of an undercut groove and to demarcate a longitudinal slot of the rail section, said guide arm having a neck extending through the slot and a cylindrical guide member formed integrally with the neck and engaging behind the border webs.
    • Claim:
      9. The composite section of claim 7 wherein the groove is undercut and exhibits a trapezoid cross section, with the guide arm having a trapezoid cross section.
    • Claim:
      10. The composite section of claim 1 wherein one of the rod members has an undercut groove and the other one of the rod members has a guide arm received with play in the groove.
    • Claim:
      11. The composite section of claim 10 wherein one rod member has opposing border webs to demarcate the undercut groove and to form a lateral longitudinal slot, said guide arm having a neck extending through the slot and formed in one piece with a cylindrical guide member.
    • Claim:
      12. The composite section of claim 11 wherein the other rod member is formed with stop surfaces extending parallel to the border webs.
    • Claim:
      13. The composite section of claim 1, wherein one of the rail sections is provided with an anchoring groove opposite the attachment foot of the corresponding rod member and a wire placed in said anchoring groove between the attachment foot and the groove, thereby increasing resistance against longitudinal displacement.
    • Claim:
      14. A heat-insulated composite section for doors, windows and facades, comprising
    • Claim:
      at least one insulating rod arranged between the rail sections and having longitudinal edges; and
    • Claim:
      compensation means provided in a longitudinal connection zone between interconnected components for eliminating a flexure of the rail sections when subject to uneven temperature rise, wherein the compensation means is formed by a sliding-type guidance which is effected by a groove formed in one rail section and a guide arm formed on the insulating rod and received with play in the groove and wherein the one rail section has opposing border webs facing the insulating rod to define the groove in the form of an undercut groove and to demarcate a longitudinal slot of the rail section, said guide arm having a neck extending through the slot and a cylindrical guide member formed integrally with the neck and engaging behind the border webs.
    • Claim:
      15. A heat-insulated composite section for doors, windows and facades, comprising
    • Claim:
      compensation means provided in a longitudinal connection zone between interconnected components for eliminating a flexure of the rail sections when subject to uneven temperature rise; wherein the compensation means is formed by a sliding-type guidance which is effected by an undercut groove formed in one rail section and a guide arm formed on the insulating rod and received with play in the groove, with the guide arm having a trapezoid cross section.
    • Claim:
      16. A heat-insulated composite section for doors, windows and facades, comprising
    • Claim:
      a plurality of metal rail sections
    • Claim:
      compensation means provided in a longitudinal connection zone between interconnected components for eliminating a flexure of the rail sections when subject to uneven temperature rise; wherein the insulating rod is of two-part configuration having a first rod member connected with one rail section in a manner to resist a longitudinal displacement, and a second rod member connected with another rail section in a manner to resist a longitudinal displacement, with the first and second rod members being connected at a central location by the compensation means in the form of a sliding-type guidance; wherein the one of the rod members has an undercut groove and the other one of the rod members has a guide arm received with play in the groove wherein the one rod member has opposing border webs to demarcate the undercut groove and to form a lateral longitudinal slot, said guide arm having a neck extending through the slot and formed in one piece with a cylindrical guide member.
