Definitions

  • the invention relates to a thermal compensation spacer for connecting together external and internal aluminium profiles in an aluminium joinery system.
  • the spacer also compensates stresses occurring between the external and internal aluminium profiles.
  • Thermal spacers in form of strip elements are used in the production of insulated aluminium profiles and serve to increase thermal insulation of aluminium profiles used for manufacturing window and door structures.
  • Low thermal conductivity of the thermal spacers in the profiles used to make window and door constructions prevents cold air penetrating indoor spaces in winter (freezing) and, likewise, hot air in summer (excessive heating).
  • the thermal spacer which generally is formed as a longitudinal strip element, is assembled with the external and internal aluminium profiles by crimping said aluminium profiles at the edge regions along the longer edges of the strip element on both sides.
  • thermal spacers commonly used in aluminium joinery systems are disclosed e.g. in the Polish patent application P. 388324 and in the protection rights for utility models PL 66 696 Y1 and PL 66 697 Y1 .
  • Thermal spacers made of polymer materials not only have good thermal insulation properties, but also high load capacity and are designed to carry access loads together with (external and internal) aluminium profiles.
  • the material most commonly used for producing thermal spacers is polyamide (PA) reinforced with glass fibre, but some other materials are also used, e.g. acrylonitrile-butadiene-styrene (ABS) terpolymer, polyethylene terephthalate (PET), or NorylTM (amorphous mix of poly(phenylene oxide, poly(phenylene ether) and polystyrene).
  • thermal spacers may vary in shape: straight, omega-shaped (in cross-section), chamber type, complex and other.
  • One of the known methods for eliminating deformations of composite aluminium profiles is to use special compensation spacers with local notches of various shapes (rectangles, triangles, circles, etc.) that to some extent compensate the stress between the external and internal aluminium profiles.
  • special compensation spacers with local notches of various shapes (rectangles, triangles, circles, etc.) that to some extent compensate the stress between the external and internal aluminium profiles.
  • Notches of the spacer are masked with a cover integrated with the spacer, which results in aesthetic appearance without affecting the spacer operation.
  • the aim of the present solution was to overcome the problems referred to above and associated with the use of known solutions, and in particular to provide good stress compensation between the external and internal aluminium profiles in case of large temperature differences between the environments on the external and internal profile sides, and the simplest possible method for manufacturing thermal spacers and installation of spacers in aluminium joinery systems.
  • the present invention relates to a thermal compensation spacer for connecting together external and internal aluminium profiles in an aluminium joinery system, said spacer being formed as an elongated strip element, made by coextrusion of two materials of different hardness, wherein at least the edge regions along longer edges of the strip element designed to be crimped in the external and internal aluminium profiles are made of a hard polymer material, and at least one region between said edge regions is made of a soft and elastic polymer material.
  • the hard polymer material is selected from polyamide (PA), acrylonitrile-butadiene-styrene (ABS) terpolymer, poly(ethylene terephthalate) (PET).
  • PA polyamide
  • ABS acrylonitrile-butadiene-styrene
  • PET poly(ethylene terephthalate)
  • the soft and flexible polymer material is a thermoplastic elastomer.
  • the thermal spacer of the invention consists of three regions extending longitudinally over the entire length of the strip element, wherein the two distal edge regions are made of a hard polymer material, and between them there is an intermediate region made of soft and elastic polymer material.
  • the thermal spacer of the invention consists of five regions extending longitudinally over the entire length of the strip element, wherein the two distal edge regions and the middle region are made of a hard polymer material, and between each of the distal edge regions and the middle region there is an intermediate region made of soft and flexible polymer material.
  • the thermal spacer of the invention has closed air chambers at least on a portion of its length.
  • the thermal spacer of the invention has additional projections on one or both sides for attaching rails or caps.
  • the thermal spacer is composed of two components of different hardness and is produced by co-extrusion, i.e. extrusion of several layers which may differ in structure and colour.
  • the hard external (in cross sectional view) parts of the spacer as in conventional spacers, are crimped in the external and internal aluminium profiles, respectively.
  • the middle part or parts are made of soft and flexible material.
  • the use of flexible parts permanently connected to the hard parts allows to compensate the differences in the displacement of external and internal profiles resulting from different temperatures affecting the external and internal parts of the window and door structures.
  • the co-extrusion process enables to obtain a multicomponent spacer showing required rigidity and strength as well as to maintain the desired tolerances of linear and cross-sectional dimensions.
  • the thermal spacers of the invention can be manufactured in all the currently commercially available shapes, i.e. straight, omega-shaped (in cross-sectional view), in a three-dimensional and chambered variants, with caps, in complex systems, etc.
  • Fig. 1 is a cross-section of two embodiments of straight-shaped thermal compensation spacers of the invention, with the embodiment with one intermediate region of soft and flexible polymer material being shown at the top, and below there is an embodiment with two such regions divided by a middle region of hard polymer material.
  • Fig. 2 is a cross-section of two embodiments of omega-shaped thermal compensation spacers of the invention, whereby - similarly to fig. 1 - the embodiment with one intermediate region of soft and flexible polymer material is shown at the top, and below there is an embodiment with two such regions divided by a middle region of hard polymer material.
  • Fig. 3 is a cross-section of four embodiments of chamber type thermal compensation spacers of the invention, varying in number and arrangement of chambers and regions of hard polymer material and of soft and flexible polymer material.
  • Fig. 4 is a cross-section of six embodiments of thermal compensation spacers with caps of the invention, showing various ways of fastening the caps and numbers of regions of hard polymer material and of soft and flexible polymer material.
  • Fig. 5 is a top view of a thermal spacer fragment in the embodiment with one intermediate region of soft and flexible polymer material
  • fig. 6 is an analogue view of the embodiment with two such regions dividing the middle region of hard polymer material.
