Definitions

  • the present invention relates to a cam arrangement and specifically to a cam arrangement for a lock mechanism such as a lock mechanism for a door or window.
  • Cams are used in lock mechanisms for closures such as windows and doors. Generally, they provide a point of contact or engagement with a corresponding slot or aperture, for example in a frame associated with the window or door.
  • the cam may operate under the operation of a handle. For example, the cam may rotate or move linearly under the operation of the handle to engage with the slot or aperture.
  • cams of this type are typically provided in two separate sizes, 7.7mm and 9mm (measured with reference to the distance the cams project from a support member of the lock mechanism).
  • United Kingdom Patent No. GB2124291 discloses a fastener for sliding doors or windows, the fastener comprising a bolt assembly adapted to co-operate with a receiver assembly operable by an actuator under the control of a handle, the bolt assembly including a sprung loaded headed bolt arranged to be received within aligned openings in two overlying rails of the receiver assembly, and on rotation of the handle the actuator slides a retainer one of the rails relative to the other rail to engage and hold the bolt head.
  • United Kingdom Patent No. GB2322905 discloses a longitudinally-displaceable transmission bar of a shoot bolt mechanism, for a window or door, comprises a laterally projecting locking member arranged to become engaged with a keep, the keep being secured to a fixed frame member opposing an edge member of the openable door or window.
  • the locking member comprises a sleeve which is retained on a stud which projects from the transmission bar, a compression coil spring being retained between a head flange of the stud and an inner end flange of the sleeve to urge the sleeve inwardly towards the transmission bar.
  • a head flange of the sleeve, at its outer end, is arranged to slide beneath spaced retaining flanges of the keep when the locking member is introduced into engagement with the keep.
  • a further cam arrangement is known from US 6 817 637 B .
  • a cam arrangement for a lock mechanism of a closure configured to be mounted on a supporting member of the lock mechanism, the supporting member having an upper surface and an opposed lower surface

  • the cam arrangement is configured such that, in use, the biasing member is provided in an abutting relationship with the lower surface of the supporting member.
  • a cam arrangement may be provided where the cam can be moved between two axial positions.
  • a single type of cam arrangement can be provided which covers both cam sizes conventionally used in applications of this type. Providing a biasing member to move the cam allows for the cam to be automatically reset to one of the two axial positions.

  • the biasing member may be compressed between the surface of the supporting member and the surface of the cam or surface of the further component of the cam arrangement upon movement of the cam from the first axial position to the second axial position.
  • the first axial position comprises a position at which the cam, when mounted to the supporting member of the lock mechanism, projects a first distance from a surface of the supporting member.
  • the second axial position comprises a position at which the cam, when mounted to the supporting member of the lock mechanism, projects a second distance from the surface of the supporting member.
  • the second distance is greater than the first distance.
  • the first distance may be approximately 7.7mm.
  • the second distance may be up to 10.0mm, for example approximately 9.0mm.
  • the size of the cam i.e. the distance it projects from the supporting member
  • the cam arrangement of the invention may therefore be used in applications requiring either a conventional 7.7mm cam or a 9.0mm cam.
  • cam sizes are envisaged and are dependent on the operating requirements of the cam arrangement which may encompass a range of different distances.
  • the cam is moveable from the first axial position to the second axial position against the biasing force provided by the biasing member.
  • the cam is moveable from the second axial position to the first axial position with the biasing force provided by the biasing member.
  • the cam may be pulled against the biasing force provided by the biasing member from the first axial position to the second axial position.
  • the cam may be pulled against the biasing force as a result of the cam engaging with a corresponding slot or aperture in a frame of the closure.
  • the biasing member may comprise a compressible biasing member, and the biasing force provided by the biasing member may arise via compression of the biasing member.
  • the cam may be moved against the biasing force provided by the biasing member by compressing the biasing member.

  • the extendable biasing member may comprise a resilient material, or may comprise a spring, for example.
  • the cam arrangement may comprise a spacer with which the biasing member may be operably connected to.
  • the biasing member may be positioned in an abutting relationship with the spacer.
  • the spacer may be integrally formed with a portion of the cam arrangement.
  • the biasing member may be configured to move the cam with the biasing force provided by the biasing member by pushing against a surface of the spacer.
  • the spacer may be configured to push against the biasing member upon moving the cam against the biasing force provided by the biasing member.
  • the biasing member may be provided between the spacer and a surface of an associated supporting member such that the biasing member is compressed between the spacer and the supporting member when the cam moves from one axial position to the other against the biasing force.
  • the cam arrangement may comprise an additional spacer operable to act as an end stop to retain the cam in its first axial position.

  • the cam 14 is moveable from a first axial position as shown in Figures 1-3 , and a second axial position against a biasing force provided by the wave washer 18 (see Figure 4 ). Specifically, movement of the cam from its first axial position to its second axial position acts to compress the wave washer 18.

  • the chamfered portion 17 is configured to engage with a corresponding surface in a slot or aperture in a frame of the closure.
  • the shape of the chamfered portion 17 is such that, upon engagement with the corresponding surface in the slot or aperture in the frame, the cam 14 may be urged against the biasing force provided by the biasing member 18, moving the cam 14 from its first axial position to its second axial position.
  • the intermediate spacer 24 is provided adjacent to the upper surface 28 of the supporting member 16 and is operable to act as an end stop to retain the cam 14 in its first axial position - e.g. to prevent the cam 14 moving past its first axial position to a position where it projects less than 7.7mm from the upper surface 28 of the supporting member 16.

This compression gives rise to the biasing force provided by the biasing member 18 to urge the cam 14 back to its first axial position.
  • the supporting member 16 consists of an upper supporting arm 16a and a lower supporting arm 16b.
  • Figures 1-3 show the cam arrangement 10 being operably mounted to the lower supporting arm 16b, and the cam arrangement 10' being operably mounted to the upper supporting arm 16a.

  • movement of the supporting arms 16a, 16b with respect to one another results in relative movement of the cam 10 along the slot 38 in the upper supporting arm 16a. This may be as a result of movement of the cam 10 along the slot 38 which remains substantially stationary relative to the lock mechanism 12, or movement of the supporting arm 16a with respect to the cam 10 which remains substantially stationary relative to the lock mechanism 12. Further, movement of the supporting arms 16a, 16b with respect to one another causes relative movement of at least one of the cams 14, 14' with respect to a corresponding slot or aperture in a frame of the closure - e.g. to cause the cam 14, 14' to engage with the slot or aperture.
