Definitions

  • This invention relates to sealing strips for framed closures, and in particular to those whose frames are formed from extruded profiles of thermoplastic material which are mitred and thermally bonded (welded) at their ends to form the frame.
  • a casement window closure comprising a glazing panel held in a frame of extruded unplasticised polyvinylchloride is a typical example of such a closure.
  • a sprue is formed at the weld interface. If any sealing strip present is formed of a weldable material that will also form a sprue. Any such sprue can form a mechanical stop at the corner of the frame which prevents proper closure of the window. It is accordingly necessary to remove the weld sprue and this has been a common practice in the past. Unfortunately, if there is a seal already in place, this sprue is not easily accessed at the corner and in order for its proper removal, if there is a seal present, such removal must be performed manually. This negates the advantage of pre-positioning the seal. Furthermore, if the seal sprue is of a soft sealing material this does not lend itself to easy removal. Again a manual operation is required to remove the seal sprue.
  • a sealing strip comprising a retaining web adapted to be secured into a slot in a frame member, which retaining web is sealingly attached to an elongate sealing lip formed so as to give rise to no more than a small sprue.
  • sprue formation due to the sealing lip must be kept as low as possible.
  • Such sprue formation is a function of the mass per unit length of the material of which the sealing lip is made.
  • One way of minimising such sprue formation is to use a thin lip. This can, however, give rise to difficulties in effecting a reliable weld between different sealing lips at a frame corner due to their inherent flexibility and problems in obtaining proper registration of the two lip ends as the mitred frame ends are offered up to one another, and it is accordingly preferred that such a sealing lip comprises a foamed material.
  • the retaining web is preferably of barbed form, so that its retention in the slot is promoted.
  • the retaining web of the sealing strip incorporates flanges which project to each side of its retaining web so that they are adapted to overlie the face of a frame member to either side of its slot.
  • the invention extends to an extruded closure frame member incorporating an elongate slot retaining a sealing strip wherein the sealing strip comprises a flanged retaining web which is inserted into said slot with its flanges overlapping the face of the frame member to either side of the slot and which is sealingly attached to an elongate sealing lip formed so as to give rise to no more than a small sprue.
  • the invention also includes a method of manufacturing a frame for a closure which frame comprises extruded frame members incorporating sealing strips, such method comprising the steps of:
  • the retaining web is thermally stable at temperatures at which the frame material can be welded.
  • the retaining web is suitably of a thermosetting plastic material for example an ethylene propylene co-polymer rubber.
  • the foamed material of the sealing lip should be of a thermoplastic material which is weldable at temperatures at which the frame members are weldable.
  • a polyurethane foam material is especially suitable.
  • the foam material of the sealing lip is preferably encased in a skin. Such a skin may be formed from polyethylene.
  • an appropriately shaped sealing strip in accordance with this invention has the effect of inhibiting sprue formation on welding of the frame members in the immediate vicinity of the sealing strip. This avoids or substantially avoids the disadvantage or difficulty in removing any sprue material in the immediate vicinity of such a sealing strip, and in particular from beneath such a strip.
  • a sealing strip generally indicated at 1 comprises a retaining web 2 which is provided with a barbed head 3 for insertion into and retention by the walls of a slot in a window or other closure frame member.
  • the retaining web 2 also has lapping flanges 4 and 5 which will overlie portions of the frame member when the sealing strip is assembled to that member.
  • a sealing lip 6 is formed by a skin 7 filled with foam material 8.
  • the sealing lip skin 7 is secured to the upper and lower faces of one of the lapping flanges 5 in order to secure the lip to the retaining web 2.
  • the sealing lip 6 may be formed continuously on the retaining web 2 by in situ blowing of the foam 8 in which case the foam material may be used to adhere the skin 7 to the lapping flange 5.
  • the retaining web is most preferably of a thermosetting material. Synthetic rubbers such as EPDM are suitable.
  • an opening light of a casement window comprises an opening frame 10 and a double glazing panel 11 secured in it by a lath 12.
  • the window has a fixed outer frame 13.
  • Sealing between the opening frame 10 and the glazing unit 11 is effected by a pair of sealing strips 1 which are inserted into undercut slots 14 in the frame 10 and lath 12. Sealing between the opening frame 10 and the fixed frame 13 is likewise effect by two sealing strips 1, fitted into undercut slots 14 in the opening frame.
  • Figures 2 illustrate various stages in the manufacture of a frame for a closure such as a window or door.
  • Figure 2a shows the end of a length of extruded thermoplastic frame-forming material which has been cut at 45° for forming a mitre at a corner of a finished frame. It will be seen that a sealing strip 1 having a sealing lip 6 and a lapping flange 4 has been inserted into the frame member 1 so that it is mitred at the same time as the frame member 10.
  • Figure 2b illustrates a stage in heating the end of a frame member 10 preparatory to welding it to a second like member. End portions 101 become melted and shrink back as shown in Fig 2c to leave end portions of the sealing strip retaining web 2 standing proud.
  • the retaining web 2 of the sealing strip 1 is formed of a material which can withstand the heat applied to soften and melt the frame member for welding.
  • Fig 2c the mitred ends of two frame members are brought face to face. First contact is between the ends of the two retaining webs 2 held thereby. As the frame members are brought closer together, the ends of those sealing strip retaining webs 2 are compressed and pressed back along their respective slots, and as further pressure is exerted, the ends of the frame members come into contact, are pressed together and the still soft ends of those frame members are welded together and a sprue 102 is formed. That sprue 102 formed of the hard frame material will require removal, as is conventional, for aesthetic and practical reasons. If the sprue formed is higher than the sealing lip, it can prevent any sealing contact between the frame member 10 and some other member, e.g. a glazing panel or another frame member, and this is plainly not to be desired. Removal of the sprue is facilitated because sprue formation beneath lapping flanges such as 4 of the retaining web is inhibited.
