Definitions

  • the present invention relates to mechanisms for latching and/or locking, and in particular to mechanisms for latching/locking vents such as doors.
  • Door locks are well known wherein a key is rotated to extend or retract a deadbolt from a door lock mechanism into and out of a keep in a fixed door frame. During rotation of the key, a clip attached to the deadbolt is lifted over an upstand and thereby moved from a first fixed position to a second fixed position. The upstand prevents the deadbolt from being moved without the use of the key. Good security is thereby provided.
  • a sprung-biased latch extending from a door for engagement in a keep in a fixed door frame.
  • the latch can be withdrawn either by using a key or by turning a door handle, depending upon the arrangement in a particular case. If the latch is controlled by a door handle, in some circumstances only a single handle will operate to retract the latch on one side of the door; in other circumstances, handles on both sides of the door will operate the latch. The latch can then be withdrawn by a user standing on either side of the door.
  • locking mechanisms have been developed wherein rotation of a door handle can drive a drive bar which acts on one or more further bolts positioned elsewhere on the door. Multi-point securing of the door in the fixed door frame can thereby be achieved, providing improved security. If the door handle is about halfway up the door, the drive bar can act on a bolt towards the top of the door and also a bolt towards the bottom of the door, thereby providing three-point locking in the fixed door frame.
  • the present invention aims to address the problem of "follow-on crime".
  • a mechanism for latching a vent comprising drive means, a latch and a drive bar, wherein the drive bar cannot be driven by the drive means until the latch is withdrawn.
  • the latch engages the drive bar to prevent motion of the drive bar.
  • the latch may be withdrawn by the drive means.
  • a deadbolt may engage the drive bar, the deadbolt needing to be withdrawn by rotation of a key before the drive bar can be moved.
  • the drive bar is driven by the drive means to control at least one further latch or bolt.
  • a locking means controls motion of the latch.
  • the drive means preferably includes at least one handle.
  • a mechanism for latching a vent comprising a latch, a drive means and a locking device, wherein when the locking device is deactivated, the latch is held retracted, thereby allowing the drive means to open the vent.
  • the latch is held retracted by a pin driven by the locking device. More particularly, the pin may be held by a sprung clip.
  • the drive When the latch is held retracted, the drive preferably drives a drive bar to retract a plurality of latches or bolts.
  • a manual snib for holding the latch retracted is preferably controllable independently from the locking device.
  • the locking device may be deactivated by turning through two revolutions. During the first revolution a deadlock may be withdrawn from the drive bar and during a second revolution the latch may be retracted and held.
  • a mechanism for latching a vent such as a door, comprising opposing drive means provided on opposite sides of the mechanism, wherein the drive means function independently.
  • the drive means are coaxial. More preferably, they are separated by a plate, possibly a plate made from plastics material.
  • At least one of the drive means preferably acts on a latch.
  • the latch is preferably biased into its active position.
  • a projection may be provided on a side of the latch to allow the drive means on that side of the mechanism to withdraw the latch. Such a projection may be screwed into the latch.
  • a projection may be provided on each side of the latch, thereby allowing both drive means to withdraw the latch independently.
  • a lever preferably acts between the drive means and its respective projection on the latch.
  • a further aspect of the present invention provides a mechanism for locking a vent, comprising a plurality of locking points or bolts, a drive bar acting between the locking points and a plurality of triggers which, when activated, cause the locking points to lock.
  • all the triggers must be activated to allow the locking points to lock. This requirement prevents unwanted extension of a locking point prior to closing of the vent.
  • a trigger preferably extends from a face plate of the mechanism. Each trigger is preferably activated by being depressed upon closing of a vent in its frame.
  • Each trigger preferably has a chamfered face to facilitate activation.
  • Each locking point or bolt is preferably sprung-biased towards an extended position ready for activation.
  • a locking mechanism 1 includes a gearbox 3 housing a latch 5 and a deadbolt 7 and carrying a drive bar 9.
  • the gearbox 3 is also adapted to receive a handle in a square drive 11 and a "Eurocylinder” lock (not shown) in an aperture 13.
  • the latch 5 is biased outwardly by a coil spring 15. Retraction of the latch 5 can be achieved by rotation of latch lever 17a about pivot 19a abutting a latch screw 21a fixed in the latch 5.
  • the latch lever 17a is driven by a cam surface 23a on the square drive 11a.
  • latch lever 17b A similar combination of latch lever 17b, pivot 19b, latch screw 21b, cam surface 23b and square drive 11b can be found on the opposite side of the latch 5, as shown in figure 3 . If the latching mechanism were mounted in a door (not shown) of a room, figure 2 shows the view from outside the room and figure 3 shows the view of the mechanism from inside the room.
  • the latch lever 17a will have nothing to act upon so will not be able to withdraw the latch 5 during operation of the square drive 11 a. Thus, the latch 5 cannot be withdrawn from outside of the room (or dwelling), thereby providing a degree of security.
  • the latch screw 21 b were to be removed from the latch 5, the latch lever 17b would have nothing to bear against and it would not be possible to use the square drive 11 b on the inside of the door to withdraw the latch 5. Some other unlocking mechanism would be needed.
  • Mechanism 1 also includes a deadbolt 7 which is mounted for sliding engagement in the gearbox 3 through an aperture 29 in a face plate 31.
  • the deadbolt includes a slidable detent 33 which travels in a cut-out 27 (cf. figure 1 ) between locked and unlocked positions.
  • the locking and unlocking of the deadbolt 7 is achieved by means of the cylinder lock 45 shown in figure 4 .
  • the drive bar 9 has a small cut-out 35 for receiving a flange 37 extending from the latch 5.
  • the drive bar 9 also includes a larger cut-out 39 for receiving a block 41 formed on the side of the deadbolt 7.
  • the drive bar 9 is unable to move to activate second and third latching/bolting devices/modules spaced from the gearbox 3.
  • the block 41 on the dead bolt is situated within the cut-out 39 in the drive bar 9, this too prevents movement of the drive bar 9.
  • the locking mechanism 1 is viewed from the "inside". Due to the external latch screw 21 b having been removed, rotation of the outside handle (not shown) will rotate the square drive 11 b and the latch lever 17b, but this will not result in withdrawal of the latch 5. If the latch 5 is not withdrawn, the drive bar 9 cannot be moved to unlock any related latches or bolts. Thus, the door is secure.
  • the door can be opened.
  • a key (not shown) in the cylinder lock 45
  • the deadbolt 7 is withdrawn as shown in Figure 4b and links of a latch/cylinder drive bar 47 are aligned.
  • a cam 49 of the cylinder lock 45 drives the latch/cylinder drive bar 47 upwards such that a latch lever 51 drives the latch 5 inwards.
  • a latch/cylinder drive retaining pin (not shown) is forced into a sprung clip, thereby preventing the latch/cylinder drive bar 47 from moving.
  • the latch 5 is thereby also held retracted.
  • the key can then be rotated and removed, without releasing the latch 5.
  • the square drive 11 b returns to its rest position and the latch 5 is released. When closed, the door will then latch and be secure from intruders. If the handle is driven upwards, the locking modules will engage in the frame keeps and the flange 37 on the latch 5 will engage with the drive bar 9, further securing the door.
  • the proposed locking mechanism can be adjusted prior to fitting to prevent "follow-on crime".
  • a fitter of the mechanism must disengage the latch screw 21 b (or 21 a dependent on whether the door is left or right handed) from the outside of the latch 5 prior to fitting the locking mechanism. Then, when the lock has been fitted, the following operation is required to gain access the dwelling:
  • the locking mechanism 1 is set to avoid "follow-on crime" by having the external latch screw 21 b removed.
  • a face plate snib 61 is provided, as shown in figure 5 .
  • Snib 61 is a simple slider in the face plate 31 which can be moved to retain the latch 5 retracted as a user exits though the door and wishes to be able to reopen the door from the outside.
  • the latch 5 is held retracted, so both the internal and external handles of the door can be used to drive bar 9 to release the various locking points without any fear of the latch 5 re-engaging with the locking bar 9 and preventing access from outside. This is useful when a user wishes to leave the dwelling without the key. However, the door cannot be secured/locked when the snib 61 is in operation.
  • a handle snib 63 may be used.
  • the snib 63 is situated within the gearbox 3 and is driven by a lever (not shown) accessible from outside the gearbox casing.
  • the latch 5 can be held retracted.
  • the inactive and active positions are defined by a sprung steel clip 65 engaging in the recesses 67, 69 in the snib 63.
  • the auto-bolt operation is achieved by virtue of individual actuators associated with each latch or bolt.
  • the actuator 71 which extends from the face plate 31 of the module 73 is forced inwards, and this releases a sprung-loaded bolt 75.
  • the latch 5 and the top and bottom locking actuators 71 must be depressed simultaneously to fire the bolts 75, thereby preventing misfires or problems associated with a door which is open with a bolt or latch 75 already extended.
  • Each remote bolt module 73 includes a portion of drive bar 77 for controlling the motion of its bolt 75, a bolt spring 79 for urging the bolt 75 outwards, and an actuator 71 and associated spring 81.
  • the module drive bar 77 includes an inclined slot 83, which carries a stud 84 integral with the bolt 75, and a cutout 85 for receiving a portion of the actuator 71.
  • the actuator 71 When the actuator 71 is triggered, it is pushed out of the cutout 85 and allows the drive bar 77 to move.
  • the spring-biased bolt 75 is guided by the slot 83 into its exposed active position.
  • the drive bar 77 is driven by rotation of a handle acting on the main gearbox 3 to withdraw the bolt 75.
  • the actuator is once again urged into the cutout 85 and thereby prevents further movement of the drive bar 77 until such time as the actuator is again triggered.
