Definitions

  • the present invention relates to a locking apparatus and in particular to a locking apparatus for a roof window.
  • Roof windows generally consist of a frame, within which a sash is mounted which rotates about a pivot point between itself and the frame and carries the glass.
  • the sash and frame also typically have a latch which secures the two components together when the sash is in the closed position.
  • Modern latches also possess an additional feature which allows the user to move the latch handle and permit ventilation of the room without affecting the lock between the sash and the frame. While ventilation can occur without unlocking the latch between the sash and the frame, when the latch handle is moved into the ventilation position, the sash can be readily rotated from either the interior or exterior of the window.
  • the present invention provides a window comprising a frame, a sash pivotally mounted within the frame, and a latch means for releasably coupling the sash and frame together in a closed coplanar position, the window having a sash movement restriction means mounted thereon comprising a movable barrier means operable between a locking position and an open position via biasing means the movable barrier means has a sloped contact surfaces formed for allowing movement of the sash or frame over the sloped surface of the movable barrier means.
  • the window is a roof window.
  • the sash is substantially restricted from moving away from the closed position.
  • the sash is free to pivot relative to the frame when the latch means is in the disengaged position.
  • the latch means having a locked position for securely coupling the sash and frame together in a coplanar position, the latch means having a ventilation position for securely coupling the sash and frame together in a co-planar position allowing air to pass between the frame and the sash, and the latch means having a disengaged position wherein the frame and sash are decoupled allowing the sash to pivot about the frame.
  • the sash when the latch means is in the ventilation position or in the disengaged position, the sash in unable to pivot away from the closed position when the moveable barrier means is in the locking position and is operable between the sash and the frame.
  • the movable barrier means is locatable in or on the frame or sash.
  • the movable barrier means is locatable at least partially in a recess formed in the frame or sash facing surface of the sash or frame respectively.
  • the sash movement restriction means is located proximal to one end of the window.
  • the sash movement restriction means is located proximal to the end of the window having the latch means.
  • a recess is formed in the frame for receiving at least a part of the movable barrier means.
  • the biasing means is disposed between the frame or sash and the movable barrier means.
  • the biasing means is integrally formed with the movable barrier means.
  • the biasing means and movable barrier means is formed as a homogenous one piece component.
  • the biasing means is disposed between a recess in the frame or sash and the movable barrier means.
  • the movable barrier means allows the sash to move from an open position to a closed position but prevents the sash from moving from a closed position to an open position.
  • the movable barrier means is movable from a locking position to an open position and back to a locking position by moving the sash past the movable barrier means in the direction of closing of the sash.
  • the movable barrier means is movable between a locking position and a closed position by moving the sash past the movable barrier means in the direction of closing the sash.
  • the movable barrier means is movable from a locking position to an open position manually by a user.
  • the movable barrier means protrudes from the recess in the frame or sash.
  • the movable barrier means is in a locking position when the sash is in a closed position thereby inhibiting the movement of the sash unless the movable barrier is manipulated by a user.
  • the movable barrier means protrudes from, is flush with, or is below the surface of the frame or sash.
  • the movable barrier means has a sash locking member protrudable from the recess of the sash or frame and a biasing member located within the recess.
  • the biasing member comprises a flexible element mechanically coupleable between the sash locking member and the recess.
  • the flexible element comprises a flexible member mechanically coupled to the sash locking member.
  • the flexible member extends along part of the base of the recess.
  • this allows the flexible member to extend along the base of the recess as a result of compression of the flexible member due to depression of the sash locking member.
  • the flexible member has a heel spacing the flexible member away from the base of the recess, the flexible member extending to a toe resting on the base of the recess.
  • a gap exists between the underside of the flexible member and the base of the recess.
  • the sash locking member is mechanically coupled to the heel of the flexible member protruding forward from the heel in a jaw like configuration, defining an expanding mouth between the flexible member and the sash locking member.
  • the mechanical coupling between the sash locking member and the heel of the flexible member is flexible.
  • a gap exists between the top of the flexible member and a base of the sash locking member.
  • this gap allows the sash locking member to move in and out of the recess between the locking position and the open position.
  • the flexible member is a flexible ramp.
  • an insert is located in the recess.
  • the insert is an open profile thin walled insert.
  • the insert is formed for snug fitting in the recess.
  • the insert has a generally C-Channel cross section.
  • the insert and the movable barrier means have co-operating retaining members for retaining the movable barrier means in the recess.
  • the insert has two overhang members protruding part of the way across the opening of the insert.
  • the sloped surface of the movable barrier means is orientated relative to the sash or frame so that closing the sash causes the sash or frame to move in a direction up the sloped surface simultaneously depressing the movable barrier means between the locking position and the open position.
  • the sloped surface of the movable barrier means is orientated relative to the sash or frame so that closing the sash causes the sash or frame to move in a direction up the sloped surface simultaneously depressing the movable barrier means into the recess between the locking position and the open position.
  • a section through a roof window indicated generally by the reference numeral 1 having a frame 2, a sash 3 pivotally mounted within the frame 2 and a latch not shown for releasably coupling the sash 3 and frame 2 together in a closed coplanar position.
  • the window 1 has a sash movement restriction arrangement 4 mounted on the frame having a movable barrier 5 operable between a locking position as shown in the drawing and an open position by a biasing arrangement 6.
  • the movable barrier 5 When the movable barrier 5 is in the locking position, the sash 3 is substantially restricted from moving away from the closed coplanar position.
  • the movable barrier 5 When the movable barrier 5 is in the open position, the sash 3 is free to pivot relative to the frame 2 when the latch is in the disengaged position.
  • the latch has a locked position for securely coupling the sash 3 and frame 2 together in a coplanar position.
  • the latch also has a ventilation position for securely coupling the sash 3 and frame 2 together in a co-planar position allowing air to pass between the frame 2 and the sash 3.
  • the latch also has a third disengaged position wherein the frame 2 and sash 3 are decoupled allowing the sash 3 to pivot about the frame 2.
  • the sash 3 in unable to pivot away from the closed position when the moveable barrier 5 is in the locking position operating between the sash 3 and the frame 2. This prevents access from the outside by intruders simply pushing a bar through the ventilation gap to open the latch when the latch is in the ventilation position or by simply pushing the sash 3 open if the latch is in the disengaged position.
