Definitions

  • This invention relates to a key for joining hollow profiles in the formation of a decorative grille which can be inserted in a glazing panel to simulate traditional Georgian windows.
  • Such keys are widely known in the double glazing industry as "centre keys”.
  • Known centre keys includes a body portion and a number of tongues which project from the body portion for insertion into the open ends of respective lengths of profile.
  • the body portion usually remains visible in the finished glazing unit and is designed to provide a matching, aesthetically attractive square edged interface between the cut ends of the profiles.
  • Injection mouldings are widely used to form a one piece component incorporating both the attachment tongues and the centre section.
  • the polymer used is a light-fast, UV stable grade of pigmented engineering plastics, but the mass of the centre section can cause so-called weld lines to appear, and can produce shrinkage at the edges which causes the moulded centre to gape apart from the raw cut edges of the profiles.
  • An aim of the present invention may be viewed as being to overcome the limitations of both integrally moulded centre keys and composite keys with metal covers.
  • the present invention proposes a centre key of the kind set forth in the appended Claims.
  • the main part 1 of the centre key is an integral plastics moulding which includes a substantially square body part 10 having four tongues 12-15 of known form projecting from its four sides to receive four profile sections 16, shown in outline only.
  • the tongues each have a pair of upstanding longitudinally extending ribs 17 which are continued across the body part 10 to be continuous with the ribs 17 of the opposite tongue.
  • the ribs are bridged by a transverse bar 19.
  • the opposite rear face of the main part 1 is of substantially the same configuration, and a pair of substantially identical caps 3 are provided to completely cover and enclose the opposite faces of the body part 10 (only one being seen in Fig. 1).
  • the front wall 32 of the caps is substantially square and may be of any desired style (e.g. "square cut” or "pyramid") to provide an aesthetically attractive interface between the profiles 16.
  • an abutment wall 33 depends from each of the four straight edges of the front wall 32, being slightly inset from the extreme marginal edge of the front wall which thus forms a projecting lip 38.
  • the four abutment walls 33 are each provided with double notches 34 to receive the ribs 17 when the cap is superimposed on the body portion 10, in which position the abutment walls 33 are positively located between the four transverse bars 19.
  • the two caps 3 may be secured to the body portion 10 by means of a suitable adhesive, by a suitable plastics welding technique, or by means of co-operating snap-engageable formations on the cap and body portion.
  • the leading cut end eventually abuts the wall 33 which provides a positive stop for the profile.
  • the position of the cut end is therefore determined relative to the cap rather than the body portion, ensuring that the end is covered irrespective of the relative positions of the cap and body portion.
  • the projecting lip 38 closely overlies the cut end of the profile, hiding the cut end from view. Although the lip is only short, its length is still sufficient to cover the end face of the profile in the event of normal shrinkage in the length of the profile.
  • the caps and body portion can be formed with an aperture for insertion of a resilient glass buffer, to prevent chattering against the glass sheets in a double glazing panel.
