Definitions

  • the present invention relates to frame members and to frames suitable as door or window frames assembled from the frame members.
  • the frame members and frames are formed from plastics materials.
  • a frame member having a main hollow cross section assembled from two components and having a ridge extending longitudinally therealong, said ridge being produced upon assembly of the two components by uniting a flange of the first component which flange extends at an angle to a portion of the first component which portion forms at least part of one side of the main hollow cross section, with a flange of the second component extending at an angle to an extension of a portion of the second component which portion forms at least part of an adjacent side of the main hollow cross section such that the end of the flange of the first component abuts against the flange of the second component, a projection being formed on the first or the second component for engaging the other component and locating the abutment of the flanges of the two components.
  • a frame member having a main hollow, rectangular, cross section assembled from two components wherein the first component has a flange extending substantially perpendicularly to a portion of that component which portion forms one side of the main hollow rectangular cross section of the frame member and the second component has a flange, extending substantially perpendicularly to an extension ofa portion of the second component which portion forms an adjacent side of the main hollow rectangular cross section of the frame member, when in the assembled form the end of the flange of said first component abutting against the flange on said second component, said second component being provided with at least one projection which engages with the corner of the first component between the flange of the first component and the portion of the first component which forms one side of the main hollow rectangular cross section, as the two components are brought together to guide the end of the flange of the first component into abutting relationship with the flange of the second component.
  • a frame member of generally rectangular cross section assembled from a component having a generally U-shaped cross section and a capping component which forms the fourth side of the generally rectangular cross section of the frame member, said capping component being of a generally channel'sectioned cross section having a base and flanges forming the sides of the channel, which flanges extend substantially perpendicularly to extensions of each end of the base, and when the U-shaped component and said capping component are assembled, the ends of flanges extending from the sides of the U of the U- shaped component abut against the flanges of said capping component, said capping component being provided with projections projecting from the channel section between the base and the extensions of the base, said projections engaging with the corners of the U-shaped component between the sides of the U and the flanges thereon as the U-shaped component and the capping component are brought together so as to guide the flanges of the U-shaped component into abutting relationship with the flanges ofthe capping
  • the invention also concerns door or window frames when assembled from frame members according to the invention.
  • Both the outer fixed frame and the inner moving frame may be made in accordance with the invention and the term door or window frames is to be understood to embrace this meaning.
  • the fixed outer frame and the inner moving sash frame of a window may be assembled from frame members according to the invention.
  • a preferred method of producing the components is to compression mould them from a partially cured sheet of reinforced thermosetting resin, e.g., glass fiber-reinforced polyester resin.
  • the hollow cross section of the frame member should be substantially rectangular.
  • substantially rectangular we intend to include cases where at least one side, and possibly more than one side, of a component is made slightly nonperpendicular to its adjacent side, e.g., by from /2 to 3. It is particularly advantageous to provide for this degree of nonperpendicularity in components which are formed by moulding since this facilitates removal of the moulded component from the mould.
  • the ridge is preferably also of hollow cross section, although it need not be hollow and may assume a solid form.
  • the flanges of the first and second components are preferably arranged substantially perpendicular" to said portion of the first component forming at least part of one side of the hollow cross section and to the extension of the second component respectively.
  • substantially perpendicular we include cases where the flanges are slightly nonperpendicular to their associated portion or extension, e.g., by from V2 to 3.
  • the projection is preferably formed on the second component for ease of manufacture of the component, particularly when compression moulding ofa partially cured sheet of reinforced thermosetting resin is used, and is preferably located at the junction of the extension and the portion of the second component extended by the extension. It is also desirable to make the general plane of the projection perpendicular to the portion of the second component forming at least part of said adjacent side and to its extension, and to connect the projection to this portion and extension. It is not necessary for the projection to extend the whole length of either component on which it is formed. Indeed it may only extend for a minor proportion of this length or may be broken into a plurality of spaced projections.
  • the projection may take the form of a support and locating means for supporting the flange of the first component in spaced relationship to the extension of the second component when the ridge is hollow.
  • the projection is preferably cutaway to provide a spigot for location in a corresponding socket in the first component, the spigot and socket being equidistant from corresponding ends of their respective components thereby serving to longitudinally locate the components with respect to each other.
  • the frame member is produced from the two components by bonding together the abutting surfaces of the flanges of each and bondingthe projection of one component to the surface of the other component against which it abuts.
  • Production of the frame member may be effected by assembling the two components with the flanges and projection in an unshaped condition.
  • one or both of the flanges and/or the projection may be shaped to facilitate assembly, for instance channel may be formed in either of the flanges or projection to accommodate the mating part, or the abutting surfaces of the flanges and projection may be bevelled or may be formed with interengaging teeth or studs and cavities.
  • a longitudinal channel may be moulded into the ridge for accommodating a weather sealing strip.

  • one side of the generally rectangular cross section of the frame member which is shown approximately by the dotted lines, is formed by a portion 1 of a first component forming part of a side of the hollow cross section of the frame member.
  • a flange 2 is formed on the end of portion I extending in a generally perpendicular direction to the portion 1.
  • the second frame component has a portion 3 forming an adjacent side of the generally rectangular cross section, and a flange 4 extending in a generally perpendicular direction to an extension 3a of portion 3.
