Definitions

  • the present invention relates to a structural assembly having a first section, preferably a light alloy section, suitable to be joined to at least one second element, in particular, a heat insulation element.
  • the present invention can be used especially in the manufacture of door and window frames, curtain walls and frames for display cabinets and show-cases or small constructions such as trade fair stands.
  • the structural elements used to provide heat insulation are joined to the supporting structural sections proper by slotting a tongue-like portion of each heat insulation element into a matching channel made in each supporting section so as to rigidly secure the heat insulation element to the light alloy element.
  • the operation by which the heat insulation element is inserted and secured to the structural section consists in sliding the slotting portion of the insulation element lengthways into the matching channel in the supporting section and then rolling, that is, strongly compressing, a lateral portion or arm of the channel so as to plastically deform it against the slotting portion, thus holding it securely inside the channel, as document FR 1489331 discloses.
  • the slotting portion of the insulation element usually consists of a first and second portion between which there is a separate metal contrast bar designed to reinforce the insulation element not only to oppose the pressure exerted on the portion or arm of the channel to be deformed but also to compensate for any geometrical irregularities so as to prevent the slotting portion of the insulation element from sliding out of the channelled section.
  • the aim of the present invention is to improve the structural elements of the type described above, in particular by simplifying the joints and also by eliminating the need for the separate metal contrast bar and the adhesive.
  • first structural element has a channel with a tongue made inside it designed to securely join the slotting portion of the second structural element to the channel eliminates the need for the separate metal bar and the adhesive used in prior art. This translates as savings on components and production costs.
  • Figure 1 illustrates in cross section a part of a structural assembly extending lengthways, for example, a window frame or similar assembly comprising a light alloy section 12 extending lengthways, designed to be applied to the outside of a building and connected, through a heat insulation element 16 extending lengthways (made from heat insulating material) to another longitudinal section 14, also made of light alloy, designed to be applied to the inside of the building.
  • a light alloy section 12 extending lengthways, designed to be applied to the outside of a building and connected, through a heat insulation element 16 extending lengthways (made from heat insulating material) to another longitudinal section 14, also made of light alloy, designed to be applied to the inside of the building.
  • Figure 1 illustrates in particular one half of a door or window frame shoulder which is symmetrically completed by a second heat insulation element (not illustrated) connecting the sections 12 and 14 in exactly the same way to the element 16 and which forms with the latter a heat insulating air space 18 between the outside section and the inside section of the assembly.
  • the section 12 has a channel 20 which extends lengthways and is broadly in the shape of a "C”, designed to receive and retain a matching shaped portion 22 of the heat insulation element 16.
  • the channel 20 of the section 12 has an opening 17 at the front, an endwall 19, on the side opposite the opening 17 and opposing lateral surfaces 21 and 23 which converge towards the front so as to hook and retain the portion 22 of the heat insulation element 16.
  • the lateral surfaces 21 and 23 of the channel 20 end at corresponding edges 17' and 17" on opposite sides of the opening 17.
  • the heat insulation element 16 also extends lengthways and, as illustrated in Figure 3, has a slotting portion 22, broadly in the shape of a "C" and being suitable in size for sliding lengthways into the channel 20 of the section 12, said shaped slotting portion forming a central groove 25 with an opening 27 at the front and an opposite endwall 29.
  • the lateral surfaces of the groove 25 in the slotting portion of the heat insulation element are formed by arms or wings 24 and 26 which can be elastically deformed crossways and between which there can conveniently be placed - as shown in Figure 1 - a tongue 28 that projects from the endwall 19 of the channel 20 of the section 12 and extends lengthways parallel to the slotting portion 22 of the second structural element 16.
  • Said tongue 28 by fitting into the groove 25 made in the slotting portion 22 of the heat insulation element, creates an inseparable joint between the slotting portion 22 on the second structural element 16 and the channel 20 in the first structural element.
  • the tongue 28 also has suitable means that, when the force on the second structural element 16 tends to disengage it from the channel 20 (in the direction labelled A in the drawings), the lateral faces of the slotting portion 22 of the second structural element 16 are forced against opposite walls of the channel 20 in the first structural element 12.
  • the reinforcing tongue has flat surfaces 32 and 34 that come into contact with the flexible opposite parts 24 and 26 of the element 16 - in particular, the plane surfaces 36 and 38 of these - which diverge in the perpendicular disengagement direction A from the channel 20.
  • This setup is particularly advantageous. Every time the portion 22 is pulled in the direction of the arrow A of disengagement from the channel 20 of the section 12, said diverging surfaces 32 and 34 act in conjunction with the opposite surfaces 36 and 38 of the flexible parts and, through reciprocal expansion of the flexible parts 24 and 26, increase the pressure that the slotting portion 22 exerts as a whole on the lateral surfaces of the channel, thus strengthening the fit between the slotting portion 22 and the channel 20.
  • diverging surfaces in this preferred embodiment of the invention are plane surfaces, other shapes are also possible, without departing from the scope of the inventive concept.
  • plane diverging surfaces might constitute only a part of the lateral profile of the tongue or the tongue might have a curved shape along all or part of its length.
  • the lateral edges of the tongue might even not diverge, although in this case the advantage would not be so evident.
  • the tongue instead of two diverging surfaces 32 and 34, the tongue has only one inclined surface (either the surface 32 or the surface 34) that comes into contact with a corresponding surface (36 or 38) of a single flexible part (24 or 26) of the slotting portion 22 of the heat insulation element so that, when the heat insulation element is forced in the disengagement direction A, the slotting portion 22 is pressed against a corresponding wall (40 or 42) of the channel 20, thus increasing the pressure between the slotting portion 22 and the section channel 20 in proportion to the applied disengagement force.
  • the tongue has only one inclined surface (either the surface 32 or the surface 34) that comes into contact with a corresponding surface (36 or 38) of a single flexible part (24 or 26) of the slotting portion 22 of the heat insulation element so that, when the heat insulation element is forced in the disengagement direction A, the slotting portion 22 is pressed against a corresponding wall (40 or 42) of the channel 20, thus increasing the pressure between the slotting portion 22 and the section channel 20 in proportion to the applied disengagement force.
  • the opposite lateral surfaces 40 and 42 of the channel 20 of the section engage the corresponding surfaces 44 and 46 of the portion 22 of the heat insulation element 16 and converge in the direction A in which the slotting portion is disengaged from the channel.
  • said surfaces 32 and 34 of the tongue 28 and the corresponding surfaces 36 and 38 of the flexible parts 24 and 26 of the portion 22, are located, respectively, upstream, relative to the direction A of disengagement from the channel, of the converging surfaces 40 and 42 and of the corresponding surfaces 44 and 46 of the slotting portion 22.
  • the reinforcing tongue 28 has a broadly triangular shape which widens in the disengagement direction and has a transverse end surface 48 that is substantially flat, to match a corresponding flat face 50 of the bottom 29 of the groove 25 in the slotting portion 22 of the heat insulation element.
  • edges 54 and 56 between the front face 48 and the diverging plane surfaces 32 and 34 of the tongue 28 are rounded.
  • edges 58 and 60 between the bottom face 50 of the groove 25 and the plane diverging faces 36 and 38 of the lateral faces of the groove 25 in the slotting portion 22 are also rounded edges 58 and 60 between the bottom face 50 of the groove 25 and the plane diverging faces 36 and 38 of the lateral faces of the groove 25 in the slotting portion 22.
  • Another advantageous characteristic of the invention is that, in the direction of disengagement A of the slotting portion 22, at least one edge 54 of the tongue 28 is aligned with an opposite portion of edge 17' of the channel opening 17 so as to further reinforce the fit between the slotting portion 22 and the channel 20 in the section.
  • the transverse edges of the free ends of the arms or transversely flexible parts 24 and 26 of the slotting portion 22 on the heat insulation element are flat and designed to come into contact with the parts of the bottom 19 of the channel 20 that are on either side of the tongue 28.
  • the slotting portion therefore substantially matches the channel in the supporting section.
  • each of the two diverging surfaces 32 and 34 of the tongue 28, within the section channel and the corresponding opposite surfaces 36 and 38 is inclined by an angle of approximately 20° with respect to the axis of symmetry M (drawn with a dot-dashed line in the illustration).
  • the tongue 28 is integral with the endwall 19 of the channel 20 in the first structural element or section 12 and is preferably made in a single block with the first structural element 12.
  • the sections 12 and 14 are made of aluminium and the heat insulation element 16 is made of rigid, heat insulating plastic.
