Definitions

  • the invention relates to a joint structure for interconnecting adjacent ends of framing members for a sash or a window or doorframe.
  • Framing members are typically extruded thermoplastic profiles each member having a substantially identical cross-sectional profile.
  • a sash or a window or doorframe is generally made from the framing members by welding mitered members with one another at the frame corners.
  • the framing members described in US4492063A comprise:
  • a synthetic resin is used as the bonding agent which causes this bonding, which synthetic resin has thermoplastic or thermoplastic properties and thus enables the glass fibers to be deflected during welding and pressing together of the ends of the frame pieces.
  • the reinforcing element in US4492063A is therefore restricted to glass fiber roving, that can be deflected during welding.
  • the present invention provides a joint structure in the manner as described in claim 1 that can be used for reinforcements like e.g. steel wires that do not require the above mentioned deflection during welding.
  • the joint structure for interconnecting adjacent ends of said members according to the invention includes:
  • Connecting means can be friction welding, ultrasonic welding or hot plate welding. Preferably hot plate welding is used.
  • Each member is preferably formed of a hot plate weldable material, and wherein the connecting means comprises means for heat welding the first and second mitered portions through the first and second mating surfaces.
  • Hot plate weldable materials are typically thermoplastic materials, like polyvinylchloride, polypropylene or polyethylene.
  • An advantage of the present invention is that an anti-sticking layer, generally polytetrafluoroethylene (PTFE), on the welding plate that is used to heat the surfaces to be weld, is not damaged by the reinforcing elements.
  • PTFE polytetrafluoroethylene
  • the joint structure of the invention preferably comprises intermediate support walls parallel to the first and second side walls.
  • the side walls, support walls and part of the connecting walls forming one, optionally more tubes and the recessed surfaces proximate the intermediate support walls of the second member.
  • the reinforcing elements in the joint structures of the invention can be fibers or fiber reinforced strips.
  • the fibers include mono and multifilament fibers.
  • the multifilament fibers are preferably glass, aramid or carbon fibers; the monofilament fibers are typically steel wires, but also roving of said materials as well as metal strips can be used.
  • Each member may include a euro groove for a closing mechanism.
  • Each member may also include a glass receiving channel formed in the first connecting wall, the glass receiving channel for supporting the interior and exterior sides of the window glass assembly.
  • the invention further relates to a sash or a window or doorframe, comprising a glass assembly with four members joint to form a frame, with a joint structure according to the invention.
  • Fig. 1 shows a joint structure for a first (1) framing member comprising first (10) and a second (11) side walls provided with steel wires (13) , the side walls spaced by first (14) and second connecting walls, and intermediate support walls (17, 18) parallel to the first (10) and second (11) side walls, the side walls, support walls and part of the connecting walls forming tubes (21 a/b,22a/b) and webs (19, 20) connecting the support walls with the side walls, wherein the joint structure for interconnecting the first framing member with a second framing member ( Fig.
  • 2 (2)) includes two flanges (23, 24) disposed at the end of the first member comprising the side walls (10, 11), the support walls (17, 18) and part of the connecting walls, the flange having a first squared end surface extending substantially orthogonal to the longitudinal axis of the first member (1); a first mitered portion (25) disposed at the end of the first member, the first mitered portion spanning between said flanges and having a first mating surface defined thereon, wherein the first mitered portion (25) has a width defined along a direction extending between the first (10) and second (11) side wall of the first member.
  • An additional advantage of the tubes 21a/b and 22a/b is an increased stiffness of the flanges (23,24).
  • the first squared end surface is preferably provided with an injection moulded cover plate. Said cover plate further ensures the water tightness of the window.
  • the member of Fig. 1 includes a euro groove (16) for a closing mechanism.
  • Fig 2 shows a joint structure for a second framing member comprising first (10) and a second (11) side walls provided with steel wires (13), a second mitered portion (26) disposed at the end of the second member (2), the second mitered portion (26) having a width substantially the same as the width of the first mitered portion (25), and the second mitered portion (26) spanning from the first side wall (10) of the second member (2) toward the second side wall (11) of the second member (2), wherein the second mitered portion (26) has a second mating surface defined thereon for abutting the first mating surface on the first mitered portion (25), and wherein the second mitered portion defines recessed surfaces (27, 28) proximate the intermediate support walls (17, 18) of the second member (2); two second squared end surfaces (29, 30) extending substantially orthogonal to the longitudinal axis of the second member between the side walls of the second member and the recessed surfaces (27, 28) of the second mitered portion, wherein two recesses (31, 32) are
  • the joint structure of the invention is obtained by connecting the members shown in Fig. 1 and Fig. 2 with connecting means through the first and second mating surfaces, with the flanges (23, 24) on the first member (1) received in the recesses (31, 32) defined in the second member (2); whereby the flanges (23, 24) and the second squared end surfaces (27, 28) define a squared edge on the side walls of the members.
  • the wall thickness of the walls to be welded (14, 15) is preferably between 2 and 7 mm, thus obtaining sufficient weld strength.
  • Fig. 3 shows a joint structure for a first (1) framing member comprising first (10) and a second (11) side walls provided with a glass roving (13).
  • Fig 4 shows a joint structure for a second (2) framing member comprising first (10) and a second (11) side walls provided with a glass roving (13).
  • the joint structure of the invention is obtained by connecting the members shown in Fig. 3 and Fig. 4 with connecting means through the first and second mating surfaces, with the flanges (23, 24) on the first member (1) received in the recesses (31, 32) defined in the second member (2); whereby the flanges (23, 24) and the second squared end surfaces (27, 28) define a squared edge on the side walls of the members
  • Fig. 5 shows a window constructed with the joint structures of the present invention with two first framing members (1) and two second framing members (2).
  • Fig. 6 shows a cross section of framing members 1 and 2 with first (10) and second (11) side walls, steel wires (13), the side walls spaced by first (14) and second (15) connecting walls, and intermediate support walls (17, 18) parallel to the first (10) and second (11) side walls, the side walls, support walls and part of the connecting walls forming tubes (21a/b,22a/b) and webs (19, 20) .
