Definitions

  • the present invention relates to security fittings for windows, doors and the like closures.
  • Casement windows are susceptible to forced entry by a lever force applied to the opening vent frame by a crowbar or the like inserted into the rebate between the vent frame and the surrounding fixed frame to force apart the vent frame and fixed frame.
  • multi-point locking mechanisms such as espagnolettes arranged to secure the vent frame at a plurality of spaced apart positions around the periphery.
  • the present invention has been made from a consideration of this problem and has for its object the provision of a security fitting of simple construction that resists forcing of the vent frame when closed.
  • a security fitting for a window, door or the like comprising a vent frame supported for opening movement relative to a surrounding fixed frame, the fitting comprising respective coupling means arranged in use to extend lengthwise of opposed side edges of the vent frame and fixed frame and cooperating within a rebate or gap between the opposed side edges when the vent frame is closed to resist separation of the side edges in a direction substantially normal to the direction of opening movement of the vent frame.
  • the invented security fitting anchors the vent frame against application of a lever force applied by inserting a crowbar into the rebate between the vent frame and fixed frame whilst permitting normal opening and closing of the vent frame.
  • the coupling means have respective formations arranged in use to interlock when the vent frame is closed to prevent the side edges being forced apart in the plane of the fixed frame.
  • the formations may be generally of L or U shape providing interlocking flanges extending parallel to and spaced from the side edges.
  • each coupling means is separate from the associated frame and may be secured thereto by any suitable means.
  • each coupling means may have a base flange for securing to the associated frame by screws or the like.
  • each coupling means may be formed integrally with the associated frame.
  • each coupling means may be incorporated in an extrusion for assembly of the associated frame.
  • one of the coupling means is provided by a keeper for fastening means arranged to secure the vent frame closed.
  • the fastening means may have a bolting member movable from an inoperative position to an operative position for engagement with the keeper to secure the vent frame closed.
  • the bolting member comprises a curved plate mounted for rotation about an axis extending generally parallel to the rebate such that a leading edge of the plate is engageable with the keeper to urge the vent frame towards the closed position.
  • the other coupling means provides a support for the underside of the curved plate when engaged with the keeper.
  • the engagement between the plate and the keeper is reinforced to resist separation thereof.
  • the keeper has a cut-out providing clearance for the other coupling means for opening and closing the vent frame, and the curved plate is engageable with the keeper on either side of the cut-out.
  • a window, door or like closure comprising a vent frame supported for opening movement relative to a surrounding fixed frame with opposed side edges of the vent frame and fixed frame defining a rebate when the vent frame is closed, and a security fitting comprising respective coupling means extending lengthwise of each side edge and arranged to interlock within the rebate when the vent frame is closed to prevent the opposed side edges being forced apart in the plane of the fixed frame.
  • a timber casement window 1 comprising an outward opening vent frame 2 mounted by hinges (not shown) in a surrounding fixed frame 3 for pivotal movement about a vertical or horizontal axis.
  • a lock case 4 is mortised in the side edge 5 of the vent frame 2 and is coupled by a spindle 6 to a lever handle 7 mounted on the inner face 8 of the vent frame 2.
  • the lever handle 7 is rotatable for actuation of a fastening mechanism (not shown) to secure the vent frame 2 closed.
  • the fastening mechanism may be of any suitable type providing either single or multi-point locking as will be familiar to those skilled in the art.
  • the lock case 4 may house the gearing for an espagnolette or cremone multi-point lock.
  • a security fitting 10 comprising two coupling members 11,12 respectively mounted on opposed side edges 5,13 of the vent frame 2 and fixed frame 3.
  • One of the coupling members 12 has a base flange 14 with three holes 15 by means of which it is secured to the side edge 13 of the fixed frame 3 by screws (not shown) and an L-shaped formation 16 extending along one side edge defining a channel-section recess open to the outside of the window 1.
  • the other coupling member 11 has a base flange 17 that seats against the side of the lock case 4 in the mortise and a U-shaped formation 18 extending along one side edge that locates against the lock case 4 and defines a channel-section recess open to the inside of the window 1.
  • the base flange 17 has a central clearance hole 19 for the spindle 6 and smaller clearance holes 20 on either side by means of which it is retained by screws (not shown) connecting base plate 21 of the handle 7 to the lock case 4.
  • the formations 16,18 provide flanges extendng parallel to and spaced from the side edges 5,13 which co-operate within the rebate 10 when the vent frame 2 is closed to resist separation of the opposed side edges 5,13 in a direction normal to the direction of opening movement as indicated by arrow A. In this way, forced entry from the outside by means of a crowbar or similar tool inserted into the rebate 10 to force apart the vent frame 2 and the outer frame 3 is resisted by the interlocking formations 16,18.
  • the security fitting 9 does not interfere with normal opening and closing of the vent frame 2 and is concealed in the rebate 10 between the vent frame 2 and outer frame 3 when the window 1 is closed so as not to detract from the aesthetic appearance of the window 1.
  • the coupling members 11,12 are made of metal or alloy such as aluminium and may conveniently be cut to length from extrusions of the appropriate cross-section. Alternatively, the coupling members 11,12 may be castings.
  • the base flange 14 of the coupling member 10 mounted on the fixed frame 3 may be formed to extend over the outer front face 22 of the fixed frame thereby strengthening the outer frame 3 against any attempt to force the window 1 from the outside.
  • the front face 22 may be rebated so that the flange 14 is substantially flush with the outer surface so as not to interfere with the vent frame 2.
  • the security fitting 109 comprises coupling member 111 having a U-shaped formation 118 that co-operates within the rebate 110 with an L-shaped formation 116 of a keeper 130 incorporating coupling member 112 when the vent frame 102 is closed to resist forced entry from the outside by means of a crowbar or similar tool inserted into the rebate 110 to force apart the vent frame 102 and the outer frame 103 as above-described.
  • the keeper 130 has a base flange 114 for securing to the side edge 113 of the fixed frame 103 by screws or the like (not shown) and, spaced outwardly of the formation 116 in the direction of opening movement, a longitudinal rib 131 at the outer edge for engagement by a leading edge 132 of a bolting member 133 of a fastening mechanism to secure the vent frame 102 closed.
  • the bolting member 133 comprises a curved plate located between opposed complementary concave and convex internal guide faces 134 and 135 respectively of lock case 104 mortised in the side edge 105 of the vent frame 102 opposite the keeper 130.
  • the plate 133 has a central cut-out 136 in which an actuator bush 137 mounted on spindle 106 is received for rotation by operating handle 107.
  • the bush 137 has a cam formation 138 engageable with the cut-out 136 on rotation of the bush 137 in one direction to move the plate 133 from an inoperative position to an operative position for engagement of leading edge 132 with the keeper rib 131, and to return the plate 133 to the inoperative position on rotation of the bush 137 in the opposite direction.
  • the plate 133 is simultaneously guided for rotation about an axis parallel to the rebate 110 by the guide faces 134,135.
  • the leading edge 132 is displaced towards the outside of the window 1 as the plate 133 moves towards the operative position to engage the rib 131 and urges the vent frame 102 inwards to compress seal member 139.
  • the coupling member 111 has a pair of upturned lugs 140 on the side edge remote from formation 118 to locate the member 111 on the lock case 104 for assembly purposes.
  • the formation 118 is centrally located between opposite ends of the lock case 104 and is aligned with a cut-out (not shown) in the rib 131 of keeper 130 for passage of the formation 118 to enable the vent frame 102 to be opened and closed with the plate 133 in the inoperative position.
  • the plate 133 is engageable with the rib 131 on either side of the cut-out and part of the coupling member 111 provides a curved support surface 141 for the underside of the projecting centre part of the plate 133 in the operative position to assist in maintaining engagement of the plate 133 with the rib 131 thereby further improving security against forced entry.
  • the invented security fitting has application to frames made of timber, plastics, metals, alloys or any combination thereof and that the strong interlock provided when the vent frame is closed increases the resistance to forced entry by breaking or deforming the frame sections so as to release the locking mechanism.
  • the resistance to forced entry may be increased further, especially for larger sizes of vent frame, by providing several security fittings at spaced apart positions within the rebate on one or more sides of the vent frame and, where multi-point locks are employed, each locking point may be provided with a security fitting to resist release thereof.
  • the coupling members may be separate for securing to the frames as above-described or one or both coupling members may be incorporated in the extrusions so as to be an integral part of the vent frame and/or outer frame.
