Definitions

  • the present invention relates to a lock that can be used as part of door hardware and especially to a lock for use in locking a swinging door panel in a closed position with respect to a door casing.
  • the structure of the lock includes a bolt, for example a dead bolt, movable into and out of engagement with a strike plate which may be installed on a door frame.
  • a bolt for example a dead bolt
  • strike plate which may be installed on a door frame.
  • a common latch lock (known in the trade as a "night latch") that is used to lock a door is mounted on the internal face of the door. Often an additional lock is provided to lock the door, which may be a mortise deadlock. With such an arrangement, on shutting the door, the night latch locks automatically and any additional or auxiliary locks, e. g. a mortise lock, must be locked manually by key (if locked from the outside) or with a key or a thumb turn (if locked from the inside).
  • DE37 00 891 discloses a lock having a bolt that can retracted by a key and held in an unlocked position by a hook that is disengaged by a trigger bar when it is pushed into the lock on closing the door.
  • the lock also has a further handle that can be used to operate the bolt but the handle is prevented from operating by an electromagnet unless the electromagnet is released, e.g. in an emergency or during a power cut.
  • US 4 262 504 discloses a lock having a bolt and a trigger bar.
  • the action of pushing the trigger bar into the lock causes the bolt to be extended, which tensions a spring.
  • a catch prevents the bolt from being retracted by the spring, whereby the lock is in a locked condition.
  • the catch can be removed by an electronic plunger (or manually in an emergency) thereby allowing the spring to withdraw the bolt and unlock the lock.
  • US 6 196 035 discloses a lock that includes a bolt, a trigger bar and a bolt.
  • the pushing in of the trigger causes the spring to engage behind the bolt to extend the bolt and lock the lock.
  • a user can disengage the spring and retract the bolt to unlock the lock.
  • the present invention provides a lock that locks automatically on closure of the door.
  • the lock of the present invention can be used as a primary or as an auxiliary bolt lock. This enables a door to be locked automatically by two or more independent locks, simply by the action of closing the door.
  • the lock may be a deadlock, that is to say a lock with a bolt that cannot be moved from a locked configuration to an unlocked configuration by engaging the bolt externally and forcing it inwards into the lock.
  • bolt is sometimes used to indicate a bolt having a square section, i.e. have sidewalls that generally lie in a plane that is parallel to the direction of motion of the bolt, so that an implement engaging the bolt from outside cannot get any purchase on the bolt to force it inwards to retract the bolt.
  • deadbolt is used to draw a contrast between such a bolt and a "latch bolt” that has a curved or chamfered sidewall that pushes the bolt inwards on engagement with an object, for example a doorframe or strike plate, to allow the door to close. This terminology will be used in the present specification.
  • the lock of the present invention has a bolt, which is often a deadbolt, and is designed to be fitted to a door (or other openable leaf) that can move between a closed position and an open position.
  • the lock bolt In the closed position, the lock bolt can project into a recess in a structure surrounding the door, e.g. a door frame, to lock the door.
  • the recess is usually provided in a wear-resistant plate affixed to the structure called a "strike plate".
  • a strike plate will be present but it may not be necessary, e.g. if the door frame is metallic.
  • the bolt can be moved into a retracted position by a key or a knob to unlock the door and allow it to be opened (so long as there is no other mechanism keeping it closed).
  • the knob (sometimes called a "thumb turn”) is usually provided inside a building to allow a user to open the door and exit without the use of a key, whereas a key is needed to open the lock from the outside.
  • the bolt once the bolt is moved to its retracted position, it is held by the lock in that retracted position, thereby allowing the key to be removed and the door to be opened.
  • Previously proposed automatically locking deadbolt locks require, when opening a door, that the deadbolt is held in a retracted position by means of, for example, a key or a thumb turn turned in the lock and held manually in that retracted position until the door has been physically opened, i.e. the lock has been moved free of the door frame and its associated strike plate.
  • the present invention allows the lock to be moved into an unlocked configuration and remain in that unlocked configuration without manual intervention when the door is still closed, thereby avoiding the need for a user to hold the bolt in a retracted position by means of a key or other force of retraction until the door is physically opened.
  • the lock remains automatically held in the unlocked position so that other locks can be unlocked and thus the door becomes free to open.
  • the lock includes a trigger bar that is separate from the bolt to release the bolt from its retracted position when the door is closed.
  • a trigger bar is spring biased so that it projects out of the lock when the door is opened but is forced back into the lock by the surrounding door jamb when the door is closed. It is common that such a trigger bar is used in automatically locking locks to release the bolt but this can be problematic in that the bolt can accidentally be released by the user while the door is still open, requiring the bolt to be unlocked again before the user can close the door.
  • the lock arrangement of the present invention uses the trigger bar to control the bolt such that while the trigger bar is projecting the deadbolt will always be retracted. In practice this means the lock arrangement described cannot be manipulated while the door is open so as to render the door impossible to close as with other automatically locking locks but in fact will ensure that the door may always be subject to being automatically locked.
  • the lock has a hold back for holding the bolt when it is moved to the retracted position, thereby allowing the door to open.
  • the holdback will generally engage the part of the bolt that remains within the lock casing and the engagement can be direct or indirect.
  • the lock also has a lock actuator that releases the bolt from the holdback as the door is closed and projects the bolt into the recess to lock the closed door.
  • the trigger bar generally does not engage in a recess in the strike plate, as would a latch-bolt, but instead, for example, slides over a surface of the strike plate. In other words, the trigger bar does not itself provide any locking action but rather is used to operate the bolt.
  • the arrangement of the present invention is not susceptible to accidental triggering and includes a two-stage hold back.
  • a bolt engagement e.g. a hook
  • This engagement may be released when the trigger bar moves into its projecting position as the door is opened.
  • another bolt engagement maintains the bolt in the retracted position and takes over when the first bolt engagement is released.
  • This further engagement is controlled by the action of the trigger bar and may include an arm that engages the bolt when the trigger bar is in its projecting position to maintain the bolt in its unlocked position.
  • the force of the trigger bar spring acting through the arm can maintain the bolt in its unlocked position (while the trigger bar is in its projecting position) thereby maintaining the bolt spring in tension.
  • the action of the trigger bar being moved from its projecting position to its retracted position on engagement with the door jamb causes the arm to allow the bolt to be moved into its locked position using the tension in the bolt spring.
  • the springs urging the bolt and the trigger bar to project out of the lock case may be arranged such that they cooperate with each other (rather than acting against each other as is the case in US2519808 ) therefore reducing the maximum spring force required of the trigger bar spring.
  • the bolt spring acts between the bolt and the arm so that the movement of the arm to maintain the bolt in its unlocked position reduces the tension in the bolt spring while the movement of the arm to allow the bolt to move into its locking position tensions the bolt spring.
  • the arrangement could also be used without a holdback mechanism to operate for instance as a night latch embodying features of the previously mentioned lock while including the improvements associated with the rearrangement of springs.
  • the arrangement of springs also has the benefit in that when withdrawing the bolt the withdrawal force is minimized in that only a single spring force resists the withdrawal and that spring is at the lower end of its resistance levels during said bolt withdrawal process. It is also the force of the weaker of the two springs that the bolt is withdrawn against.
  • the lock arrangement allows for the release of the first stage of the automatic holdback mechanism once the door is opened since the second stage takes over. This second stage occurs via the trigger bar which is projected forwards on opening of the door and this change in its position automatically releases the bolt from the first stage of the holdback mechanism.
  • the spring arrangement within the lock ensures that the bolt is retained in a retracted unlocked position while the door is opened and the lock disengages from the strike plate in readiness for another locking cycle as when the door is again closed.
  • An arm may be part of a central operating cam, which might control other functions of the lock, e.g. the release of the first engagement and/or the deployment of a deadlock lever, as described below.
  • a rapid release mechanism which reduces the key or thumb turn rotation required to unlock the lock, as set out in the attached claims.
  • the present invention also provided a sonic indicator which reassures the user that the lock has engaged successfully in the strike plate.
  • the lock could be used as one of two or more automatically locking locks operating on the same door.
  • a sonic indicator is proposed which would automatically sound when the lock bolt has entered the strike plate aperture. It is envisaged within the scope of the invention that this might take the form of an electrical or electronic device with a circuit being formed when the bolt enters the strike plate; the circuit could operate an electrical or electronic sonic emitter to alert the user as appropriate.
  • the sonic indicator assembly described in the invention uses the movement of a bolt into the aperture in the door frame to strike a hammer which strikes a percussion object, for example a bell but this could also be a tuning fork or other percussion object.
  • a percussion object for example a bell but this could also be a tuning fork or other percussion object.
  • the bolt it is possible for the bolt to strike the sonic indicator directly, such an arrangement runs the risk that the bolt will quickly dampen the vibration of the sonic indicator.
  • said projecting bolt movement might trigger a more elaborate mechanism with greater sonic possibilities, such as a wind up spring operated hammer mechanism or an indicator which could sound within a controlled time period after a door is shut.
  • a deadlocking feature to prevent inappropriate unlocking by external force.
  • the element which controls the deadlocking feature is the same element which facilitates the holdback of the deadbolt and this same element is again engaged directly by the unlocking feature to also remove the deadlock prior to withdrawal of the bolt.
  • the arrangement of the lock shown in figure 1 to figure 11 is fitted on a door 1 with a door edge 2 and is contained in a casing 3 with a front plate 4, and a covering plate 5.
  • the lock has two projecting members, a sliding trigger bar 6 and a sliding deadbolt 7.
  • the door 1 is co-operable with a jamb 8 which carries a strike plate 9 running parallel to the front plate 4 with an aperture 10 in the strike plate 9, said aperture being horizontally aligned with the deadbolt 7.
  • the strike plate 9 also has a cambered face 11 which is aligned with the trigger bar 6.
  • the trigger bar 6, the deadbolt 7 and other elements of the lock slide forwards and backwards, "forwards” describing the direction elements of the lock move out of the casing 3, i.e. to the left in figures 1-8 as shown, and “backwards” describing the opposite direction.
  • the projecting face of the trigger bar 6 is rounded so that when it meets the cambered edge 11 of the strike plate 9 it is forced backwards into the lock casing 3.
  • the trigger bar 6 is spring projected forwards via a compression spring 12 which runs over a cylindrical runner bar 13 which is held by a fixed slot piece 14 that is secured to the casing. At its other end, the cylindrical runner bar 13 is held on a pin 15 which is fixed between the two projecting arms 16 and 17 (see figure 2 ) of said trigger bar 6.
  • Trigger bar 6 is connected to a central operating cam 20 by a pin 21 which is also held between the two projecting arms 16 and 17.
  • the front of the trigger bar 6 runs along slots 22 and 23 in the lock casing 3 ( figure 2 ).
  • the central operating cam 20 is flat in shape and rotates about a fixed central cylinder 24. Washer 25 sits inside the central operating cam 20 to help to keep said central operating cam aligned as it rotates.
  • One arm 26 of the central operating cam 20 engages with the deadbolt 7 with a face 27 of the central operating cam 20 moving against face 28 of the deadbolt 7 during lock movements.
  • a deadlocking arm 30 (shown dotted in figures 3 , 5, 6,7 and 8 for clarity of illustration) is a plate like member which rotates about a fixed pin 35.
  • Deadlocking arm 30 has a laterally protruding pin 31 which has a roller pin 32 rotating about pin 31, said roller pin 32 bears against face 33 and face 34 of the central operating cam 20 so that, when said central operating cam rotates, it in turn rotates the deadlocking arm 30.
  • the deadlocking arm 30 also acts as a holdback hook with face 37 and face 38 of the deadlocking arm 30 acting on faces 39 and 40 of the deadbolt 7.
  • the deadlocking arm 30 is acted on by compression spring 41 which sits between a nib 42 of the deadlocking arm 30 and the lock casing 3. Faces 43 and 44 of the deadlocking arm 30 act on face 45 and face 46 of the deadbolt 7 when the lock is in the locked position.
  • the projecting end of the deadbolt 7 slides forwards and backwards through the front plate 4 and the covering plate 5 and on its opposite end the deadbolt 7 has a fixed projecting pin 47 which slides along horizontal slots 48 and 49 (see especially figure 4 ) in the casing 3, said slots 48 and 49 aiding in maintaining the position of the deadbolt 7.
  • a dotted line 50 in figures 1 , 3 and 5 indicates a voided area in the deadbolt 7 said void laterally aligning with a torsion spring 51 to allow a free movement of said spring which operates on the deadbolt 7.
  • the deadbolt 7 has a central shaft 52 that is reduced in thickness to allow an arm 53 of the deadlocking mechanism 30 to move beside it on one side and the arm 26 of the central operating cam to move on its other side (see figure 4 ).
  • a torsion spring 51 is connected to the deadbolt 7 with one arm of the spring being inserted in a hole 54 in the central shaft 52. The other arm of the torsion spring 51 is inserted into a hole 55 in arm 26 of the central operating cam 20.
  • a plate 56 which is fixed to the casing 3 sits outside the torsion spring 51 and helps to laterally restrain said spring in position as it moves backwards and forwards with the deadbolt 7.
  • a lock cylinder 57 is located in the lock casing 3 and has a nib 58 rotating a rapid releasing mechanism 59 designed to reduce the rotational path of the key to unlock the lock.
  • An extension spring 60 acts between said rapid release mechanism 59 and a fixed pin 61 which protrudes from the plate 56.
  • the rapid release mechanism 59 has curved projections 62 on either side which slide along slots 63 on either side of the lock casing 3, said slots being cyclically parallel to the rotation of the nib 58.
  • Lock cylinder 57 is held in position by a fixing screw 64 which threads through a fixed threaded member 65.
  • the rapid release mechanism 59 acts on faces 66 and 67 of the deadlocking bar 30 and on face 68 of the deadbolt 7.
  • FIG. 1 A description of the typical locking and unlocking cycle of the arrangement begins with figures 1 and 2 showing the lock in its configuration when the door is in the open position and about to be shut.
  • the trigger bar 6 is projecting fully forwards due to the influence of compression spring 12.
  • the central operating cam 20 has been rotated anticlockwise to its furthest extent and thus forces the face 27 of arm 26 against face 28 of the deadbolt 7 and thus forces the deadbolt 7 backwards.
  • the movement of pin 47 along slots 48 and 49 controls and restricts the forwards and backwards movement of the deadbolt 7.
  • the deadlocking arm 43 is held elevated by the position of the roller pin 32 against face 34 of the central operating cam 20.
  • the arrangement is unlocked (see figures 5 to 8 ) by a rotation of the lock cylinder nib 58 by either a key from the outside or a thumb turn from the inside.
  • the nib 58 rotates the rapid release mechanism 59 against the force of the extension spring 60.
  • the rapid release mechanism 59 initially meets face 66 of the deadlocking bar 30 which slightly rotates (raises) the deadlocking bar 30 thus removing the deadlock function before the deadbolt 7 is to be retracted.
  • a continuance of the rotation of the nib 58 sees the rapid release mechanism 59 meeting face 67 of the deadlocking bar 30(see figure 7 ) thus keeping the deadlocking bar 30 raised and out of the path of the deadbolt 7; concurrently the rapid release mechanism 59 meets face 68 of the deadbolt 7 and further rotation of the nib retracts said deadbolt 7 (see figure 6 ).
  • a further continuance of the rotation brings face 37 of the deadlocking bar against face 40 of the deadbolt 7 further rotating the deadlocking bar 30 and raising it until the face 38 of the deadlocking bar 30 aligns with face 39 of the deadbolt 7 and said deadlocking bar rotates anticlockwise due to bias of spring 41 thus hooking on to the deadbolt 7 and retaining the deadbolt in its retracted position as shown in figure 8 .
  • the rotational force may now be removed from the key or thumb turn and the rapid release mechanism 59 will return to its original position under the influence of spring 60 allowing the key to be removed if a key was the rotational mechanism.
  • the door 1 may now remain in the shut position with the lock in the holdback position until other locks are unlocked and the door is ready to be opened.
  • the arrangement of the present invention makes the unlocking of the other locks easier since there is no need for the user to do anything to maintain the lock of figures 1 to 10 in an unlocked condition while the other locks are unlocked.
  • the deadlocking bar 30 is so arranged that the faces 33 and 34 of the central operating mechanism 20 control the position of the deadlocking bar 30 such that the deadlocking bar 30 is held sufficiently raised when the bolt 7 initially projects forwards that face 39 of the bolt 7 has moved beyond face 38 of the deadlocking bar 30 so as not to impede its path.
  • FIG 8 and 9 shows an alternative strike plate 69 encompassing an arrangement for a sonic indicator which engages with a lock that has a spring biased forward projecting bolt.
  • Figures 8 and 10 describe this arrangement in connection with the lock as described is the arrangement but any lock that has a spring biased forward projecting bolt may be used instead.
  • This sonic indicator is intended to let a user know that the bolt has projected from the lock into the strike plate when a door has closed.
  • the lock arrangement in the invention is primarily intended for use as secondary or auxiliary locks it would be convenient to let the user know that the bolt of a lock of this type has projected into the strike plate when the door closes by emitting a noise other than the noise of a door slam.
  • the indicator is in the form of a bell structure 72 set behind the strike plate 69 and is set to ring once the deadbolt 7 projects into said strike plate aperture 78.
  • a set of rotating hammers 70 hang freely from a cylindrical bar 71 behind the strike plate aperture.
  • Bar 74 indicates a C shaped holder piece which is fixed to the strike plate at points 75 and 76.
  • the bell structure 72 is held in position at a single point by bolt 73 which screws through bar 74 and through a washer 77 into the bell structure 72.
  • a deadbolt will project from the casing into a strike plate with force and speed due to the deadbolts being spring projected forwards.
  • the hammer 70 or hammers Once the hammer 70 or hammers have been struck by the deadbolt 7 they will swing upwards to strike the bell 72. Preferably they will immediately drop back down away from the bell as remaining in contact with the bell would reduce the length of time the bell would continue to sound. Different size, shape and weight of bell can influence the sound emitted.
  • a temporary disengagement facility as shown in Figs.8 and 9 .
  • This is in the form of a disc shaped plate 79 which has shoulder sections on the lock side of the plate, the plate 79 is fixed via a threaded bolt 80 which fits freely through disc 79 to threaded nut 81, threaded nut 81 being fastened against threaded locking nut 82 such that disc 79 is freely rotated about bolt 80 between the limits of lines 83 of covering plate 5, see Fig 9 .
  • the bolt 7 will be in the retracted position.
  • the invention sets out to solve the problem of creating a secondary or auxiliary door lock which essentially replaces a manually operated deadlock with an automatically locking equivalent. It gives the advantage of including on a door set, a more comprehensive locking system whilst reducing involvement from the user. Obviously the user will not have to lock the lock as this is done automatically but less obviously the user having walked away from the doorway will no longer have to second guess whether they had remembered to double lock or not thus avoiding those all too familiar returns to a doorway to check if the door is locked.
  • the rapid release mechanism will reduce the aggravation of unlocking a lock because the key turn rotation is much reduced compared to current locks, which enables the lock to be unlocked with one swift motion and without re gripping which is necessary for instance to complete key turn of more than 180 degrees.
  • This is brought about by the use of a rotatable rapid release mechanism 59 having a larger sweep radius than the lock nib and thereby able to drawback the deadbolt 7 a greater lateral distance per degree of turn of the nib than if the deadbolt is withdrawn by the nib itself.
  • the first feature described above can be used to provide a superior lock in which a deadbolt which will extend further outside of the lock case than is common in deadbolts, thereby greatly enhancing the security of the lock which is often necessary to comply with modern requirements, specifically insurance requirements.
