Definitions

  • This invention relates to locking devices, and in particular to a locking device for use with a sliding patio door system.
  • locking device many forms are known, such as deadlocks, spring-loaded locks, bolts, etc. Such devices are perfectly adequate when used in conjunction with hinged doors and door frames. However, other forms of locking device must be utilised if the door, or other vent, is of the sliding kind, such as a sliding patio door.
  • a locking device comprising a link, a portion of which is adapted to pass through an opening of a keep, during use, and a bolt, wherein the bolt is moveable between a first position in which it is inactive and a second position in which it enters the opening to prevent retraction of the link from the keep.
  • the locking device comprises a drive means for moving the bolt between its first position and its second position.
  • the drive means may take many different forms, but preferably includes a drive rod for attachment to a handle.
  • the link may include a flattened region which abuts a wall of the opening when the bolt is in its second position, during use.
  • the link may simply include an enlarged end portion which is able to pass through the opening, but which cannot pass back through the opening when the bolt is in its active, second position.
  • the link is shaped from a flat sheet of metal. If this is the case, an end region of the link is bent to provide an enlarged effective area for preventing retraction of the link when the bolt is in its second position.
  • the bolt is preferably substantially planar and moves in a plane substantially parallel to the plane of the link.
  • a locking device according to the present invention is preferably utilised in a sliding vent.
  • the locking device it is possible for the locking device to be mounted in a support frame and for a keep to be mounted on a sliding vent for mating therewith.
  • the vent preferably slides along a track within a support frame such that, when closed, the link of the locking device penetrates a keep mounted on a substantially vertical portion of the frame.
  • the locking device may be mounted within a hollow portion of the vent adjacent an aperture through which only the link and bolt extend. Such a mounting of the locking device ensures that the locking device cannot be readily broken away from the sliding vent itself.
  • the prevention means may include a spring-biased protrusion which cooperates with a bearing plate only when the vent is closed.
  • a swing bolt engages a second keep in a horizontal part of the support frame. If such a swing bolt is included, additional locking strength is provided.
  • a sliding vent will preferably include a plurality of locking devices according to the present invention. If many locking devices are utilised, a single handle preferably actuates them all at the same time. More preferably, a lock and key are included to enable the handle to be locked when the bolt or bolts are in the active position.
  • a particularly preferred use of a locking device according to the present invention is in a sliding patio door system. Other uses can of course be envisaged.
  • each keep defines an opening having two sides, a top and a bottom, and includes grooves for engaging flanges of a channel in a support frame of a vent.
  • the grooves in the or each keep preferably engage the flanges of the channel, thereby preventing the or each keep from being pulled away from the support frame.
  • the positions of the keep can be readily adjusted as necessary during installation.
  • a locking device 1 includes a shoot bolt case 2, a drive rod 3, a shoot bolt 5, a shoot bolt cover 7 and a shaped link 9.
  • the shoot bolt case 2 includes a deep channel 11 for receiving the drive rod 3 in sliding relation thereto.
  • the shoot bolt case 2 further includes a recessed portion 13 for receiving the shoot bolt 5.
  • the shoot bolt 5 includes an arm 5a having a nose portion 5b which engages in a recessed track 15 in the shoot bolt case 2.
  • the recessed track 15 is perpendicular to the deep channel 11.
  • the drive rod 3 includes a pin 17 mounted thereon for engagement with a corresponding aperture 19 in the shoot bolt 5. Due to this arrangement, as the drive rod 3 moves up or down along the deep channel 11, the pin 17 forces the shoot bolt 5 between its active (figure 1) and inactive (figure 2) positions. The nose portion 5b of the shoot bolt 5 helps to ensure smooth movement of the shoot bolt 5 perpendicular to the drive rod 3.
  • the shoot bolt cover 7 is fixed via screws 21 to the shoot bolt case 2, thereby holding the drive rod 3 and shoot bolt 5 in position.
  • the shoot bolt cover 7 also includes two flanges 23 extending substantially perpendicularly to its main plane. These flanges dictate the position of the shaped link 9 by ensuring that the link 9 always extends over the edge of the shoot bolt case 2 (as shown in figures 4 and 5), irrespective of whether the shoot bolt 5 is in its active or inactive position.
  • a sliding patio door system 30 includes a fixed door 32 and a sliding door 34.
  • Each door 32,34 includes a large pane of glass or double glazing.
  • the sliding door 34 runs in a track 36 which engages both the top and bottom of the door 34.
  • the sliding door includes four locking devices 1 according to the present invention.
  • the four locking devices 1 are all activated by means of a single drive rod 3 which is driven by a handle 38.
  • a handle 38 When the handle 38 is in its locking position, it can be prevented from turning if a dead-lock 40 is activated by a key (not shown).
  • a handle 38 and dead-lock 40 mechanism is well known in the art.
  • the handle 38 can only be turned into its locking position when a spring-loaded release catch engages a bearing plate 42 on the track 36. Hence, the patio door can only be locked when it is in its fully closed position. Further, when the handle 38 is turned into its locking position, it drives the drive rod 3 upwards and this urges a swing-bolt 44 into a recess in the bearing plate 42. In this way, additional locking of the patio door is effected.
  • the four locking devices 1, according to the present invention, are positioned within a hollow portion of the vertical frame 46 of the sliding door 34.
  • the devices 1 are held in position by means of screws (not shown) passing through a metal skin of the vertical frame 46 and engaging threaded holes 48 (c.f. figure 3) in the shoot bolt case 2.
  • the hollow vertical frame 46 also includes apertures adjacent the locking devices 1 through which the shoot bolts 5 and shaped links 9 extend. Due to the size of these apertures and the flanges 23 of the shoot bolt covers 7, the shaped links 9 are held in position.
  • the shoot bolts 5 are all in their inactive positions (c.f. figure 2). This is because the handle 38 has not been allowed to move into its locked position, as described above. However, when the door is fully closed, the handle 38 can be swung into its locked position, thereby driving the drive rod 3 upwards.
  • the position of the shaped links 9 is altered slightly as the shoot bolts 5 engage the apertures 50.
  • locking devices 1 Although four locking devices 1 have been shown incorporated in the patio door system of figure 7, more or less locking devices 1 could equally well be used. Furthermore, although the shaped links 9 are shown manufactured from flat sheets of metal, other shapes or materials could also be used.
