Definitions

  • the present invention concerns a multipoint lock assembly. More particularly, but not exclusively, this invention concerns a multipoint lock assembly for a window.
  • Windows are often provided with a multipoint espagnolette lock assembly.
  • An espagnolette lock assembly is provided on an edge of the window, and includes a face plate, a gearbox connected to one or more rod assemblies, and multiple mushroom roller locking members connected to the rod assemblies that are moved into and out of engagement with corresponding keeps in the window frame.
  • the gearbox converts the rotary motion of a handle into linear motion which drives the rod assemblies to move the mushroom roller locking members.
  • the distance between the centre point of the handle connected to the gearbox and the external face of the gearbox is known as the backset of the lock, and different windows have different backset requirements. For example, common backset distances are 20mm and 22mm.
  • the required length of rod assemblies also varies. Typically, this requires many different window lock assemblies to be manufactured, in order that all backset and rod assembly lengths are covered.
  • the present invention seeks to mitigate the above-mentioned problems. Alternatively or additionally, the present invention seeks to provide an improved multipoint lock assembly.
  • the present invention provides a multipoint lock assembly comprising: a gearbox, and a backset facia removably connected to the gearbox, wherein the backset facia is configured such that when removably connected to the gearbox in a first orientation, a first backset is provided, and when removably connected to the gearbox in a second orientation, a second, different, backset is provided.
  • the lock assembly may be easily adjusted to provide a first backset or second backset using the same components. This may reduce the stock levels required to be held by a manufacturer or supplier.
  • the multipoint lock assembly may be a multipoint window lock assembly.
  • the multipoint lock assembly may comprise an espagnolette lock assembly.
  • the multipoint lock assembly may comprise a shoot-bolt lock assembly.
  • the multipoint lock assembly may simplify the fitment of lock assemblies and provide a lock assembly that is compatible with a wider range of windows than existing lock assemblies.
  • the multipoint lock assembly may allow easy adjustment by an engineer in the field, thus reducing the chances of incompatible lock assemblies causing installation delays.
  • the backset facia and gearbox may be provided with formations that abut when the backset facia is removably connected to the gearbox in a first orientation in order to provide the first backset, and wherein said formations do not abut when the backset facia is removably connected to the gearbox in the second orientation in order to provide the second backset.
  • the formations may be castellations that align in the first orientation such that the raised portions of the castellations abut one another when the backset facia is removably connected to the gearbox in a first orientation, and that are offset in the second orientation such that the raised portions do not abut one another when the backset facia is removably connected to the gearbox in the second orientation.
  • the backset facia may be rotated between the first and second orientations.
  • the backset facia and gearbox may each comprise one or more formations that engage so as to provide the removable coupling between the backset facia and the gear box.
  • the one or more formations of the backset facia or the gearbox may be resiliently deformable.
  • the backset facia may moulded out of a plastics material.
  • the backset facia may be moulded or machined out of a metal material.
  • the one or more formations may deform and then return to shape once engaged with a corresponding formation. This may allow the backset facia and gearbox to be clipped together.
  • the backset facia may be disconnected from the gearbox without damage to either the backset facia or the gearbox.
  • the gearbox may comprise resiliently deformable formations which facilitate the removable connection between the backset facia and the gearbox.
  • the one or more formations are arranged to engage in a first configuration when the backset facia and gearbox are removably connected in the first orientation, and arranged to engage in a second configuration when the backset facia and gearbox are removably connected in the second orientation.
  • Provision of formations on the backset facia and/or gearbox which allow the removable connection of the backset facia and gearbox may reduce the number of parts required in the multipoint lock assembly, and also simplify the assembly process.
  • fasteners such as clips, screws, and/or pins which connect the backset facia to the gearbox.
  • the backset facia may further comprise a first connection aperture and second connection aperture, the first connection aperture configured to allow the insertion and connection of a first faceplate and rod assembly, the second connection aperture configured to allow the insertion and connection of a second faceplate and rod assembly.
  • Each faceplate and rod assembly may be inserted through the respective connection aperture and connected to the backset facia by engagement of one or more cooperating formations on the faceplate and rod assembly and backset facia.
  • each faceplate may comprise an aperture which engages with a corresponding clip when the faceplate is inserted through the connection aperture.
  • the arrangement allows for the easy engagement of faceplate and rod assemblies to the backset facia.
  • the arrangement also allows for the engagement of different length faceplate and rod assemblies with the backset facia. In such a way, multipoint lock assemblies of different length can easily be provided without required large levels of stock to be maintained.
  • the arrangement may also allow offset multipoint lock assemblies to be provided, where the first faceplate and rod assembly is a different length to the second faceplate and rod assembly.
  • the invention provides a method of manufacturing a multipoint lock assembly according to the first aspect of the invention with a first backset or a second backset, the method comprising the steps of: removably connecting a backset facia to a gearbox in a first orientation to provide the first backset, and removably connecting a backset facia to a gearbox in a second orientation to provide the second backset.
  • a multipoint lock assembly comprising: a gearbox, and a backset facia removably connected to the gearbox, the backset facia comprising a first connection aperture and a second connection aperture, the first connection aperture configured to allow the insertion and connection of a first faceplate and rod assembly, the second connection aperture configured to allow the insertion and connection of a second faceplate and rod assembly.
  • Each faceplate and rod assembly may be inserted through the respective connection aperture and connected to the backset facia by engagement of one or more cooperating formations on the faceplate and rod assembly and backset facia.
  • the arrangement allows for the easy engagement of faceplate and rod assemblies to the backset facia.
  • the arrangement also allows for the engagement of different length faceplate and rod assemblies with the backset facia. In such a way, multipoint lock assemblies of different length can easily be provided without required large levels of stock to be maintained.
  • the arrangement may also allow offset multipoint lock assemblies to be provided, where the first faceplate and rod assembly is a different length to the second faceplate and rod assembly.
  • a method of manufacturing a multipoint lock assembly comprising the steps of: inserting a first faceplate and rod assembly through the first connection aperture of the backset facia, such that the first faceplate and rod assembly connect to the backset facia, and inserting a second faceplate and rod assembly through the second connection aperture of the backset facia, such that the first faceplate and rod assembly connect to the backset facia, and removably connecting the backset facia to a gearbox.
