Definitions

  • This invention relates to a fastener for a window having a fixed frame and a pivotally openable sash.
  • window fasteners In known window fasteners, it is usual to secure one part of the fastener to a fixed frame of a window and to secure the other part of the fastener to the window sash such that, when the sash is closed against the frame member, the parts of the window fastener can be engaged to hold the sash in the closed position.
  • mis-alignment of the parts of the window fastener can occur and this can make it difficult to close the sash against the frame.
  • Effectiveness of a weatherproof seal between the sash and frame is also dependant on maintenance of a fairly precisely defined relative position therebetween when the window is closed.
  • a fastener for a window having a fixed frame and a pivotally opening sash comprising a first member adapted to be secured to the frame and a second member adapted to be secured to the sash and having a manually pivotally movable handle, said first member and handle having cam surfaces engagable and adapted to operate during movement of the handle in one sense to bring the sash to a predetermined closed position relative to the fixed frame, and adapted to operate during movement of the handle in the opposite sense to move the sash in the opening direction from said pre- determined position.
  • the invention provides that the sash can be reliably closed to a pre- determined position relative to the frame, to provide a weather proof seal, and yet can be easily opened when required.
  • the movement imparted to the sash when the handle of the fastener is moved in the opening sense overcomes any initial resistance to opening movement of the sash due to distortion or misalignment thereof.
  • the first and second members of the fasteners may have formations engagable with one another as the sash approaches its closed position, to guide the sash in the general plane of the sash (i.e. in directions perpendicular to its direction of closing).
  • the first member and handle may have formations which are engagable to hold the sash at a position relative to the fixed frame which is a greater distance therefrom than the predetermined closed position. This can be used to provide a secure vent position for the sash.
  • a window sash 1 is pivotally movable towards and away from a fixed frame 2.
  • An elastomeric compression seal 3 extends along, and is fixed within, a rebate 4 in the fixed frame 2 and is sealingly engagable with the surface of a corresponding rebate 23 (shown in Figures 2 and 3) in the sash 1 when the sash is in its closed position.
  • a first member 5 of a fastener for the window assembly is fixed by screws to the frame 2 adjacent the seal 3 and comprises a metal back plate 6 from the ends of which project sash guide arms 7 and 8.
  • the guide arm 7 and 8 are provided along their length with respective wedge surfaces 10 and 11.
  • a central region of the back plate 6 is tapered to provide a ramp surface 9.
  • a pillar 12 Projecting outwardly from a central portion of the back plate 8 is a pillar 12 upon which is integrally formed a cam projection 13, with concave and convex surfaces 13a and 13b on opposite sides thereof. These surfaces co-operate with complementary surfaces on the handle of the fastener (to be described).
  • a second member 14 of the fastener is secured by screws to the sash 1 and comprises a generally rectangular base plate 15 and an elongate handle 16 mounted for pivotal movement on the base plate 15.
  • the base plate 15 is provided on three sides 17, 18 and 19 with ramp surfaces.
  • a slot 20 extends through a thickened region of the handle 16 adjacent the base plate 15 and is provided with internal surfaces 20a and 20b, shown in Figures 2 and 3, which constitute cam surfaces which co-operate in use with the cam ' surfaces 13a and 13b on the cam projection 13 of guide member 5.
  • the handle 17 is rotated in a clockwise direction and the cam surfaces 13a and 13b then co-operate with surfaces 20a and 20b positively to separate the sash 1 from the frame 2.
  • the ramp surface 9 and either wedge surface 10 or 11 can then co-operate with a corresponding surface 17, 18 or 19 of the member 14 to guide the sash 1, generally in the plane of the sash and perpendicular to its direction of closing, into the required position of correct alignment relative to fixed frame 2.
  • the handle 16 can again be pivoted in an anti-clockwise direction to secure the window in a closed position and maintain the required gap 'B' between the overlapping region 22 of sash 1 and the fixed frame 2.
  • FIG. 4 there is shown an alternative position of the fastener according to the invention in which the base plate 15 of the member 14 is secured remote from the guide member 5 by positioning the outer face 24 of the handle 16 between the cam 13 and the arm 7. In this way, the sash 1 is held at a pre-determined distance from the fixed frame 2 in a secure night-vent position.
