Definitions

  • the present invention relates to closure mechanisms. In particular, but not exclusively, it relates to closure mechanisms for use in window or door assemblies.
  • One particularly advantageous locking system combines both a shoot bolt and espagnolette mechanism.
  • this type of locking system provides numerous advantages, particularly in terms of manufacturing costs and ease of fitting, extensive testing of such systems has revealed certain areas in which security could be improved.
  • an external force such as might be applied by an intruder
  • “riding out” is thought to be caused by numerous factors, either alone or in combination, such as: deformation of the sash; failure, disengagement or distortion of the shoot bolt connecting arms that connect to the handle gearbox; or rotation of the handle to an open position under the applied force.
  • a window or door system comprising: a frame for mounting in a window or door aperture, the frame incorporating at least one receiving keep; a leaf pivotally coupled to the frame by at least one hinge, wherein the leaf is moveable relative to the frame between closed and open positions; and a closure mechanism mounted to the leaf for retaining the leaf in the closed position, the closure mechanism comprising: a shoot bolt mechanism further comprising at least one shoot bolt operable to engage a respective receiving keep when the leaf is in the closed position, wherein said at least one shoot bolt has a first surface feature shaped so as to engage a second surface feature formed within the respective receiving keep responsive to an external force being applied to the leaf when in the closed position, wherein any engagement of the first and second surface features is such as to impede withdrawal of the at least one shoot bolt from the respective receiving keep.
  • the window or door system may further comprise an espagnolette mechanism operatively connected to the shoot bolt mechanism. Where this is the case, the action by which withdrawal of shoot bolts from receiving keeps is impeded also reduces the force that is concentrated at the coupling between the espagnolette and shoot bolt mechanisms. Since it is known that the coupling is particularly prone to disengagement, distortion or failure (particularly where such a coupling is of the adjustable type), this redistribution of force within the window or door system is particularly advantageous.
  • u-PVC material may be used to form at least part of one or more of the frame and the leaf. Such material is known to be prone to flexing.
  • the window or door system may incorporate a closure mechamsm of the non- latching type. It may incorporate a non-latching handle mechanism.
  • a handle arrangement is not uncommon in window systems, particularly for smaller windows, as it permits use of a less expensive and less complex closure mechanisms that may not physically fit within the sash.
  • non-latching handles suffer from certain disadvantages. In particular, such handles are prone to rotate towards an open position when an external force is applied to any shoot bolts that are connected to them. So, by providing a mechanism for restricting the movement of the shoot bolts from respective keeps when a window sash is forced, additional security is provided even when non-latching closure mechanisms are used.
  • the window or door system may be provided with first and second surface features that are mutually co-operating chamfered surfaces.
  • the first surface feature may comprise a notch and the second surface feature a protrusion.
  • the first surface feature may comprise a groove and the second surface feature a ridge.
  • the groove and ridge extend around the periphery of the shoot bolt and the keep aperture, respectively. This allows the groove and the ridge to engage should the shoot bolt move laterally in any direction, and further facilitates manufacture of the surface features.
  • any suitable co-operating features or surfaces may be used.
  • a closure mechanism for mounting to a window or door leaf for retaining the leaf in a closed position
  • the closure mechanism comprising: a shoot bolt mechanism comprising at least one shoot bolt for engaging at least one receiving keep when the leaf is in the closed position, wherein at least one said shoot bolt has a first surface feature for engaging a second surface feature formed within a respective receiving keep responsive to an external force being applied to the leaf when in the closed position in order to impede withdrawal of the at least one shoot bolt from the respective receiving keep.
  • the closure mechanism may further comprise an espagnolette mechanism operatively connected to the shoot bolt mechanism and or a non-latching handle mechanism.
  • the first surface feature may comprise one or more of: a chamfered surface; a notch and/or a groove.
  • a window or door locking system which comprises an espagnolette locking mechanism, a first locking bolt driven by the espagnolette mechanism and moveable in the same direction as the locking movement of the espagnolette mechanism, and a second locking bolt driven by the espagnolette mechanism and moveable in an opposite direction to the locking movement of the espagnolette mechanism, wherein the first and second locking bolts have respective first surface features for engaging respective second surface features formed within respective receiving keeps responsive to an external force being applied to the window or door when in the closed position in order to impede withdrawal of the locking bolts from the respective receiving keeps.
  • the window or door locking system may comprise a first bolt unit carrying the first bolt, a second bolt unit carrying the second bolt, and a counter movement generator for moving the second locking bolt in an opposite direction to the locking movement of the espagnolette.
  • the second bolt unit may comprise the counter movement generator.
  • the window or door locking system may comprise a first rack and a second rack operatively coupled by at least one gear to produce a counter movement.

Abstract

L'invention concerne un mécanisme de fermeture destiné à une fenêtre ou une porte. Le système de fenêtre ou de porte comprend un cadre auquel est intégré au moins un taquet destiné à être monté dans une ouverture de fenêtre ou de porte. Le cadre est couplé pivotant à un battant par au moins une charnière qui permet au battant de se déplacer par rapport au cadre entre une position ouverte et une position fermée. Le battant comprend le mécanisme de fermeture mécanique destiné à retenir le battant en position fermée par rapport au cadre. Le mécanisme de fermeture comprend un mécanisme de verrou (100) comprenant au moins un verrou (102) fonctionnant de manière à se mettre en prise avec les taquets respectifs (106) dans le cadre lorsque le battant est en position fermée. Au moins un verrou (102) comprend un premier élément de surface (104), qui se met en prise avec un deuxième élément de surface (108) formé dans le ou les taquets respectifs (106) en cas de tentative de forcer le battant pour l'arracher du cadre lorsque la fenêtre ou la porte est fermée. Toute tentative de force la fenêtre ou la porte fait en sorte que le premier (104) et le deuxième (108) éléments de surface interagissent positivement de manière à contrer la tendance des verrous (102) à sortir de leurs taquets respectifs (106).
