Definitions

  • My present invention relates to a frame member of low thermal conductivity, serving as a heat-transfer-limiting member, especially for windows, doors, facades and the like. More particularly, the invention relates to a heat-transfer-limiting composite member, which may be referred to as a profile, and which is comprised itself of two structural shapes or profiles which preferably are composed of metal, bridged by two thermal conductivity-limiting ribs which space the structural shapes apart.
  • Frame members of low thermal conductivity are provided in a great variety of shapes and configurations and serve as members of low thermal conductivity in frames for windows, doors, facades and the like which are to have insulating capability, i.e. are capable of blocking the flow of heat from one side to the other of the window, door or other member provided with the frame.
  • the panel or panels of the window or door e.g. a double-pane window, are thermally insulated between two zones and by utilizing frame members or profiles of low thermal conductivity to support the panel or panels, the heat flow across the structural element can be greatly limited.
  • One of the more common constructions of such composite frame members has a pair of structural shapes or metal profiles which can be extruded from aluminum or some other light metal or light metal alloy and which can be held apart by the aforementioned conductivity-limiting webs. These webs, in turn, may be formed at their edges engageable with the structural shapes, with formations that mate with and engage in complementary formations of the structural shape.
  • the formations on the webs are cleats or beads which are engageable in grooves of the structural shapes and preferably have dovetail cross sections.
  • Another object of this invention is to provide an improved composite profile for windows, doors, facades and the like which is free from the drawbacks of earlier composite profiles for these purposes.
  • a pair of mutually spaced conductivity limiting webs each formed along respective opposite edges with a connecting formation mating with a respective one of the connecting formations of a respective one of the structural shapes whereby the conductivity limiting webs bridge between and interconnect the structural shapes, the webs being of substantially uniform thickness between the connecting formations thereof;
  • the advantages of the frame member of the invention reside in the combination of thin wall webs which have low thermal conductivity with connecting ribs which provide good mechanical properties with respect to compressive strength, tensile strength, transverse torsional strength, shear stress resistance and rigidity, as well as other strength parameters, together with good heat-blocking characteristics.
  • the wall thicknesses of the individual conductivity-limiting webs is in a range between 0.5 and 1.5 mm, and more preferably between 0.6 and 1.0 mm.
  • the wall thicknesses of the individual webs can also be between 0.8 and 2.0 mm. Best results are obtained with frame members which have two such ribs and each of the ribs has a wall thickness between 0.8 and 2.0 mm and preferably between 1.0 and 1.5 mm.
  • a particularly effective combination of parameters in the case of the thickness of the individual webs can also be between 0.8 and 2.0 mm.
  • each of the ribs can have a wall thickness between 0.3 and 2.0 mm and preferably between 0.8 and 1.5 mm.
  • the ribs can run perpendicularly to the webs or can be inclined, e.g. can cross.
  • a spacing between each of the formations of a respective one of said webs and a rib proximal thereto is 20 to 40% of a spacing between structural shapes and preferably 25 to 30% thereof.
  • FIG. 1 is a cross sectional view through a composite profile according to the invention illustrating a first embodiment
  • FIG. 2 is a view similar to FIG. 1 of a second embodiment
  • FIG. 3 is a view similar to FIG. 1 of a third embodiment.
  • FIG. 4 is a view similar to FIG. 1 of a fourth embodiment.
  • a composite profile according to the invention can comprise two preferably metallic structural shapes or profiles 1 , 2 which are interconnected by individual conductivity-limiting webs 3 which hold the structural shapes 1 and 2 apart and connect the profile into a structurally strong member.
  • the structural shapes 1 and 2 have dovetail cross section grooves or formations in which dovetail cross section cleats 4 of the webs 3 formfittingly engage. These cleats are located along the longitudinal edges of the webs 3 .
  • the webs are bridged by a plurality of connecting ribs 5 .
  • the ribs 5 are planar and lie perpendicular to the webs 3 .
  • the webs 5 cross while in the embodiment of FIG. 4, the webs 5 cross, i.e. are inclined to one another but engage the webs 3 at the transverse segments 8 which adjoin the cleats 4 .
  • the sum of the thicknesses S 1 of both webs 3 and S 2 of the two or three ribs 5 which are at right angles to the webs 3 be a minimum of 3.8 mm, a value defined as the minimum wall thickness.
  • the maximum wall thickness sum can be 10 mm and preferably is around 6 mm.
  • the wall thicknesses of the webs 3 should be between 0.5 and 1.5 mm each, preferably between 0.6 and 1 mm.
  • the wall thicknesses of the ribs 5 in the embodiment of FIG. 1 should be between 0.8 and 2.0 mm and preferably between 1 and 1.5 mm.
  • the wall thicknesses of the connecting ribs 5 should be between 0.3 and 2.0 mm and preferably between 0.8 and 1.5 mm.
  • the distance 6 between one of the connecting ribs 5 and the respective dovetail 4 should be 20% to 40% of the total distance 7 between the structural shapes 1 and 2 and preferably 25% to 35% thereof.
  • the distance 7 between the structural shapes 1 and 2 can be between 20 and 100 mm and the separation of the webs 3 midway between the structural shapes 1 and 2 can be between 10 and 100 mm.
  • the sum mentioned above should not be less than 1.6 mm.
