Field of the invention
[0001] The invention relates to a lock device comprising a lock housing with a lock bolt,
a first follower and a second follower, a blocking member which, manoeuvred by each
of the first and second followers, permits blocking of the lock bolt in a locked position
and release of the lock bolt, and also an adjustable latch device with which it is
possible to prevent the blocking member from being manoeuvred by means of the second
follower for release of the bolt. The lock device according to the invention can be
applied to locks with one or more bolts accommodated in the lock housing, and also
to locks of the espagnolette type or other so-called multi-point locks in which one
or more bolts arranged outside the lock housing are manoeuvred by means of the lock
device.
Background and prior art
[0002] Many locks, for example for dwellings, are provided, on the one hand, with a lock
cylinder which is coupled to a first follower and with which it is possible to operate
by key the unlocking and locking of a bolt included in the lock, and, on the other
hand, with a thumb turn which is coupled to a second follower and has the same function,
which thumb turn is arranged on the inside of the door. The purpose of the thumb turn
is to bring the lock to the locked position and unlocked position without having to
use a key. A disadvantage of this solution is that an unauthorized person, who has
gained access to the inside of the door, for example through a window, can easily
unlock the door by means of the thumb turn and then leave the premises through the
normal exit.
[0003] Locks are known that have a so-called thumb turn latch. This means that a person
in the possession of a valid key, for example the owner of an apartment, is able to
latch the thumb turn function and thereafter lock the door using the key. Someone
located on the inside of the door is then unable to leave the premises by this route
and must instead use another way out.
[0004] In some known locks, the thumb turn latch is activated via a button which is arranged
on the forend side of the lock and which, before locking by key, is moved to a defined
position, as a result of which the thumb turn latch is activated.
SE 431 574 describes a previously known lock with an adjustable thumb turn latch of this kind.
[0005] EP 1 840 302 A2 discloses a lock comprising a latch bolt, a hook bolt and two follower arrangements
one of which comprises a firt and a second follower. The lock has tree different operating
modes. At a first daytime mode, the latch bolt extends only a shorter distans and
allows ompening f the lock witout the use of a key. At a second saftely locking mode
the latch bolt extends to a further protruding dead-loced position and the lock may
be opened by a key from the outside and a turning knob from the inside. At a third
secured safety locking mode also the hook bolt is extended and the turning knob on
the inside is inactivated whreby the lock may only be opened by the use of a key from
the outside and possibly also from the inside.
[0006] WO 03/078767 describes another previously known lock which is provided with an adjustable thumb
turn latch and in which, after activation of the thumb turn latch, it is not possible
to determine from the outside whether the thumb turn latch has been activated or not.
[0007] For other types of locks too which comprise a first follower and a second follower
with which the lock bolt can be actuated, for example for moving the bolt or for locking
the latter, it may be desirable, by means of an adjustable latch device, to be able
to prevent one of the two followers from being used to act on the bolt.
[0008] However, previously known lock devices with adjustable latch devices of this kind
are not always able to meet the very high safety demands that apply nowadays.
Brief disclosure of the invention
[0009] One object of the invention is to make available an improved lock device with an
adjustable latch device which permits temporary blocking of the function of one of
two followers included in the lock device.
[0010] Another object is to make available a lock device of this kind that provides a high
degree of safety.
[0011] A further object is to make available a lock device of this kind in which manipulation
of the lock by insertion of objects into the lock housing is prevented or is made
considerably more difficult.
[0012] A further object is to make available a lock device of this kind in which manipulation
of the lock by blows, kicks or vibrations on the outer side of the lock housing is
prevented or made considerably more difficult.
[0013] Yet another object is to make available a lock device of this kind that is simple
and reliable.
[0014] Yet another object is to make available a lock device of this kind which facilitates
a modularized method of production of different locks forming part of a series. These
and other objects are achieved with a lock device which is of the type defined in
claim 1. The lock device comprises a lock housing which houses: a lock bolt which
is movable between an unlocked position and a locked position, a first follower and
a second follower. A blocking member is coupled to the first follower and to the second
follower. By means of each of the first and second follower, the blocking member can
be manoeuvred between a blocking position, in which the lock bolt is blocked in its
locked position, and a release position, in which the lock bolt is movable to the
unlocked position. The lock housing also receives a latch device which is adjustable
between a latching state, in which manoeuvring of the blocking member by means of
the second follower from the blocking position to the release position is blocked,
and a non-latching state, in which manoeuvring of the blocking member by means of
the second follower from the blocking position to the release position is permitted.
According to the invention, the latch device is arranged such that, when the lock
bolt is located in its locked position and the latch device has adopted its latching
state, by mechanical cooperation with the lock bolt, the latch device is blocked against
being adjusted from its latching state to its non-latching state.
[0015] With the adjustable latch device, it is possible to temporarily prevent a situation
where manoeuvring of the second follower, which can be a thumb turn follower for example,
allows the blocking member to adopt its release position, which would otherwise allow
the lock bolt to be brought to its unlocked position. The adjustable latch device
can thus be used, for example, to permit adjustment of the lock device between a "safe
at home" function and a "secure when away" function. In the "safe at home" function,
a thumb turn arranged on the inside of a door or the like can be used to quickly and
easily open the door from the inside, without using a key. In the "secure when away"
function, the thumb turn cannot be used to undo the lock. In this way, a person who
has gained unauthorized access, for example through a window or the like, will find
it impossible or very much more difficult to exit through the door.
[0016] The latch device is also designed such that, by mechanical cooperation with the lock
bolt, in the locked position of the lock bolt, it is blocked against being adjusted
from its latching state to its non-latching state. In this way, the second follower
cannot be brought into operation to manoeuvre the blocking member unless the lock
bolt is first of all moved to its unlocked position. This significantly increases
the security of the lock device compared to previously known lock devices with adjustable
latch devices. As is customary, the whole structure of the lock device is designed
and optimized to prevent the lock bolt being forced open or in some other unauthorized
way being brought from its locked position to its unlocked position. By virtue of
the mechanical cooperation according to the invention between the adjustable latch
device and the lock bolt, the high degree of safety with which the lock bolt is kept
in its locked position is also utilized to maintain the adjustable latch device in
its latching state. In this way, manipulation of the adjustable latch device, for
example by inserting manipulating tools into the lock housing or by exposing the lock
housing to vibrations, knocks or blows, is made considerably more difficult.
[0017] The latch device can comprise a first movable latch member which, when the lock bolt
is located in its locked position and the latch device has adopted its latching state,
by bearing against the lock bolt, blocks the latch device against being adjusted from
its latching state to its non-latching state. This ensures in a simple and practical
way the blocking mechanical cooperation between the latch device and the lock bolt
when the latter is located in its locked position.
[0018] The latch device can also comprise a second movable latch member which, when the
latch device has adopted its latching state, is in engagement with a coupling member
that connects the second follower to the blocking element. This permits a wide choice
regarding the placement of the second follower, the blocking member and the adjustable
latch device. At the same time, this permits simple and reliable blocking of the action
of the second follower on the blocking member when the latch device has adopted its
latching state.
[0019] The lock device can comprise an encapsulated module unit which is mounted as an integrated
unit in the lock housing and which accommodates and encloses those parts of the second
latch member and of the coupling member that are in engagement with one another when
the latch device has adopted its latching state. This makes it even more difficult
to manipulate the latch device, and its blocking by the second follower, by insertion
of manipulating tools into the lock housing.
[0020] In order to make it still more difficult to manipulate the lock device by inserting
tools into the lock housing, the first follower and the blocking member can be received
in the encapsulated module unit.
[0021] The latch device can comprise a manually operated actuation button by means of which
the latch device can be activated in order to adopt its latching state by means of
a subsequent movement of the lock bolt from its unlocked position to its locked position.
This permits simple and reliable actuation of the latch device.
[0022] The actuation button can extend through a forend or faceplate arranged on the lock
housing. This permits easy access to the actuation button, for example when leaving
home by going out through the door on which the lock device is mounted.
[0023] In addition to being coupled to the blocking member, the first follower can also
be coupled to the lock bolt for manoeuvring the lock bolt between its locked position
and unlocked position.
[0024] Alternatively or in addition to the first follower, the second follower, in addition
to being coupled to the blocking member, can also be coupled to the lock bolt for
manoeuvring the lock bolt between its locked position and unlocked position.
[0025] Alternatively or in addition to the first and second followers, a third follower
can be coupled to the lock bolt for manoeuvring the lock bolt between its locked position
and unlocked position.
[0026] The first follower can expediently be a cylinder follower, the second follower a
thumb turn follower, and the third follower a handle follower.
[0027] The lock device can comprise a bolt coupling member for driving the lock bolt between
the locked position and the unlocked position, which bolt coupling member comprises
means for coupling together with at least one bolt rod for manoeuvring at least one
bolt arranged outside the housing and forming part of a multi-point lock. In this
way, the lock device can be applied simply and reliably to many different types of
multi-point locks.
[0028] Further objects and advantages of the invention will become clear from the following
detailed description and from the claims.
Description of the figures
[0029] An illustrative embodiment of the invention is described below with reference to
the figures, in which:
Figures 1-6 are plan views of a lock device according to one embodiment of the invention,
in which certain parts have been removed, and show the lock device in different states.
Fig. 7 is a partially exploded perspective view in which parts of the lock device
illustrated in Figures 1-6 are depicted on an enlarged scale.
Figures 8 and 9 are plan views on an enlarged scale, in which parts of the lock device
illustrated in Figures 1-6 are shown after they have adopted different positions.
Detailed description of illustrative embodiments
[0030] In the illustrative embodiment of the invention shown in the figures, the lock device
forms part of a multi-point lock of the espagnolette type. The lock device comprises
a lock housing 1 which is formed by a first bent plate 2 and by a second bent plate
(not shown). For the sake of clarity in the figures, one plate has been removed in
order to show the interior of the lock housing. On a front side, the lock housing
1 is fixed to an faceplate 3 forming part of an espagnolette.
[0031] A first follower 10 in the form of a cylinder follower, a second follower 20 in the
form of a thumb turn follower, and a third follower 30 in the form of a handle follower
are received and rotatably mounted in the lock housing. A lock bolt 40 in the form
of a swing bolt is rotatably mounted in the lock housing 1 and can be manoeuvred between
a retracted unlocked position shown in Fig. 1 and a projecting locked position shown
in Fig. 2. In the projecting locked position, the lock bolt 40 extends through openings
that are formed in those parts of the bent plates 2 and of the faceplate 3 that are
arranged on the front side of the lock housing. The third follower 30 is coupled in
the usual way to a spring bolt 45. By means of a first bolt coupling member 50 and
a second bolt coupling member (not shown), the third follower 30 is also coupled to
the lock bolt 40 for manoeuvring the latter. In the example shown, the bolt coupling
members 50 are formed by plate members which are arranged parallel to each other,
are linearly displaceable and have a drive pin 51 cooperating with the lock bolt 40.
For improved clarity, one bolt coupling member has been omitted from the figures.
By means of the third follower 30, the two bolt coupling members 50 are linearly displaceable
between an upper, unlocked position shown in Fig. 1 and a lower, locked position shown
in Fig. 2. At their respective upper and lower ends, the two bolt coupling members
50 have coupling means 52 in the form of hooks for connection to bolt rods, dead bolt
rods or pull rods (not shown) forming part of the espagnolette. The bolt rods are
in turn coupled to dead bolts (not shown) which form part of the espagnolette and
which can be, for example, end or side bolts and can be configured as wedge bolts,
swing bolts, mushroom bolts or any other type of bolts.
[0032] The lock housing 1 has a front side, which is the side of the lock housing which
bears against the faceplate 3 and which, in the figures, is represented by the lefthand
side of the lock housing. The side of the lock housing 1 located opposite the front
side is a rear side which, in the figures, is represented by the right-hand side of
the lock housing.
[0033] When the lock device is assembled, a lock cylinder (not shown) is mounted on the
lock housing 1 and is coupled to the first follower 10, a thumb turn (not shown) is
coupled to the second follower 20, and a handle (not shown) is coupled to the third
follower 30.
[0034] In Fig. 1, the lock is shown in a neutral state. In this state, the spring bolt 45
projects from and the lock bolt 40 is retracted into the lock housing 1. The bolt
coupling members 50 are located in the upper, unlocked position. By turning the third
follower 30 anti-clockwise, the two coupling members 50 are driven downwards into
the locked position shown in Fig. 2, whereupon the lock bolt 40 is rotated clockwise
to a projecting, locked position, in which position the lock bolt 40 is intended to
engage with a strike plate (not shown) in a door jamb or the like. The lock has then
adopted a locked state illustrated in Fig. 2.
[0035] By turning the third follower 30 clockwise from the locked state shown in Fig. 2,
the bolt coupling members 50 are driven upwards into the unlocked position, whereupon
the lock bolt 40, by means of the bolt coupling members 50, is rotated anti-clockwise
to its retracted position. Thereafter, further turning of the third follower 30 brings
the spring bolt 45 to a retracted position (not shown). The lock device has then adopted
an unlocked state (not shown), in which either the lock bolt 40 or the spring bolt
45 engages with the strike plate. The door (not shown) or the like, on which the lock
is fitted, can then be opened. From this position, the third follower 30 and the spring
bolt 45 can return with a spring action to the positions shown in Fig. 1.
[0036] To permit secure blocking of the bolt coupling members 50 in the locked position,
the lock device comprises means for blocking the coupling members 50 in their locked
position and means for latching the blocking means in the blocking position. These
means comprise an encapsulated module unit 60 of the type described in Swedish patent
application
SE 0950896-1, which is from the same applicant as the present application and which is incorporated
herein by reference.
[0037] Referring first to Figures 1 and 7, the module unit 60 is accommodated in the lock
housing 1 and arranged on the rear side of the lock housing, i.e. at the greatest
possible distance from the front side of the lock housing 1 provided with bolt and
dead bolt openings. The module unit 60 comprises a module housing 61, which is formed
by two module housing halves 61a, of which one has been omitted from the figures for
clarity. The module housing halves 61a are composed of cast components of zinc. It
is also possible, however, to form the module housing halves differently, for example
of other cast metals or of reinforced polymer material. One module housing half 61a
has projecting pins which, in the assembled position, are received in corresponding
recesses (not shown) in the other module housing half (not shown). The pins are received
in the corresponding recesses with a press-fit. In this way, a certain cohesion of
the module housing during transport and during other handling of the unit is achieved.
When the module unit 60 is fitted in the lock housing 1, the module housing halves
61a moreover are held constantly together by the plates 2 of the lock housing 1. The
two module housing halves 61a have a number of inner recesses and together define
an inner space.
[0038] The first follower 10 is received in the module unit 60 and has a driving projection
11. A rectilinearly movable blocking member 62 is received in a channel in the module
housing halves 61a. The blocking member 62 has two downwardly projecting drive legs
63. By means of turning the first follower 10, it is possible, by the cooperation
between the driving projection 11 and the drive legs 63, to move the blocking member
62 between a release position shown in Fig. 1 and a blocking position shown in Fig.
3. The bolt coupling members 50 comprise respective blocking projections (not shown)
that extend into the module unit 60 through respective slits (not shown). When the
blocking member 62 is in its release position, the blocking projections come free
of the blocking member 62, and the bolt coupling members 50 are free to be moved.
When the bolt coupling members 50 are located in their locked positions and the blocking
member 62 is moved to the blocking position by means of the first follower, the blocking
member 62 and the blocking projections cooperate such that movement of the bolt coupling
members to their respective unlocked positions is blocked. In this way, the lock bolt
40 is also blocked in its projecting, locked position. The design and function of
the blocking member 62, and also a function latching the blocking member 62, are described
in detail in the abovementioned
SE 0950896-1.
[0039] As can best be seen from Figures 7-9, the second follower 20 is coupled to the blocking
member 62 by means of a coupling member which, in the example shown, consists of a
rack element 70 and a carrier 71, which is rotatably mounted in the module unit 60.
The second follower 20 has a toothed portion 21 which, in engagement with a corresponding
toothed portion 72 on the rack element 70, can drive the latter rectilinearly. The
rack element 70 has a drive recess 73 which, in engagement with a corresponding first
drive recess 74 on the carrier 71, can drive the carrier 71 in rotation in the module
unit 60. The carrier 71 also has two second drive recesses 75 which, in engagement
with one of the drive legs 63 on the blocking member 62, can drive the blocking member
62 in rectilinear movement between the release position thereof and the blocking position
thereof. In this way, it is possible to manoeuvre the blocking member 62 for movement
to and fro between the release position and the blocking position by means of turning
a thumb turn (not shown) coupled to the second follower 20. When the second follower
20 is turned anti-clockwise as in the figures, the blocking member 62 is driven to
the blocking position, whereas clockwise turning of the second follower 20 drives
the blocking member to the release position.
[0040] The lock device according to the present invention also comprises an adjustable latch
device 80. Referring first to Figures 7-9, the latch device 80 comprises a manoeuvring
sled 81 which is rectilinearly movable along the inner face of the front side of the
lock housing 1. A manoeuvring button 82 projects from the manoeuvring sled 81 and
extends through openings in the bent plates 2 of the lock housing and in the faceplate
3. A spring element 83 (Figures 1, 8 and 9) is arranged on the side of the manoeuvring
sled 81 opposite the button. The spring element bears against the inner face of the
bent plates 2 and in this way maintains the manoeuvring sled 81 in the position to
which the latter has been driven manually by actuation of the manoeuvring button 82.
The manoeuvring sled also comprises a lower driving projection 84, an upper driving
projection 85 and two return recesses 86, of which only one can be seen in the figures.
[0041] A first movable latch member 87 is rotatably mounted on an axle 88 which is fixed
in the lock housing 1. Two return arms 89 are likewise rotatably mounted on the axle
88, one on each side of the first movable latch member 87. A second movable latch
member 90 in the form of a latch rod, spring-loaded by means of a compression spring
91, is received in a rectilinearly movable manner in a channel in the module unit
60. The second movable latch member 90 has a front driving end 92 and a rear latching
end 93. By movement of the second movable latch member 90, the rear latching end 93
can be introduced into a latching recess 76, which is formed in the rack element 70.
The second movable latch member 90 and the latching recess 76 are arranged such that,
when the latching end 93 is in latching engagement with the latching recess, both
the latching end 93 and the latching recess 76 are received and enclosed in the module
unit 60. This makes manipulation of these parts difficult.
[0042] The function of the latch device 80 is described below with reference to Figures
1 and 4-9. In the starting position shown in Fig. 1, the lock bolt 40 is in the open
position, the blocking member 62 is in the release position, and the latch device
80 has adopted a non-latching state. The manoeuvring sled 81 is located in an upper,
inactivated position.
[0043] By moving the manoeuvring sled 81 downwards by means of the manoeuvring button 82,
the first movable latch member 87 is driven to turn anti-clockwise by means of the
upper 84 and lower 84 driving projections in contact with corresponding surfaces on
the first movable latch member 87. The first movable latch member 87 is in contact
with the driving end 92 of the second movable latch member 90 and drives the latter
a distance in the direction towards the rack element 70. The latch device has then
adopted an activated state shown in Fig. 4. In this state, the latching end 93 of
the second movable latch element 90 is not in engagement with the latching recess
76 on the rack element 70. By virtue of the fact that the first movable latch member
87 bears against the upper driving projection 85 of the manoeuvring sled 81, at a
certain angle, the compression spring 91, under the action of the second movable latch
member 90, cannot press the first movable latch member 87 back in the clockwise direction.
[0044] From the state shown in Fig. 4, the third follower 30 can be manoeuvred by means
of the handle (not shown) so as to drive the lock bolt to the projecting, locked position
shown in Fig. 5 via the bolt coupling members 50. During the rotation movement of
the lock bolt 40, a blocking pin 41 arranged on the lock bolt 40 comes into contact
with the first movable latch member 87 and drives the latter further in the clockwise
direction. The first movable latch member 87 drives the second movable latch member
90 to further movement in the rearward direction, and the latching end 93 comes into
latching engagement with the latching recess 76 of the rack element 70. The bolt coupling
members 50 are also in engagement with ends of the return arms 89, and the other ends
of the return arms are in engagement with the return recesses 86 on the manoeuvring
sled 81. During the movement of the bolt coupling members 50 in the downward direction,
the manoeuvring sled 81 is thus returned to its upper starting position.
[0045] The latch device has then adopted a latching state shown in Fig. 5. In this state
of the latch device, it is no longer possible to manoeuvre the blocking member by
means of the second follower 20 or by means of the thumb turn coupled to the latter.
However, in the state shown in Fig. 5, the blocking member 63 is still located in
its release position, in which it is possible, by means of the third follower 30,
to return the lock bolt to the unlocked, retracted position.
[0046] From the state shown in Fig. 5, it is also possible instead to manoeuvre the first
follower 10 such that the blocking element 63 adopts its blocking position. The lock
device then adopts the locked, blocked and latched state shown in Fig. 6. This state
represents the state of highest security for the lock device. From this state, the
lock device can be adjusted to any other state only if, by means of a correct key
inserted into the lock cylinder coupled to the first follower 10, the blocking element
63 is first driven from the blocking position to the release position. By virtue of
the latching engagement between the latching end 93 of the second movable latch member
and the latching recess 76 on the rack 70, it is not possible, in the state shown
in Fig. 6, to manoeuvre the blocking member 62 by means of the second follower 20
or by means of a thumb turn connected to the latter. In order to cancel this latching
of the second follower 20, it is necessary, by virtue of the mechanical cooperation
of the first movable latch member 97 with the blocking pin 45 of the lock bolt 40,
to first return the lock bolt from the locked position to the unlocked position. The
whole structure of the lock device is designed to prevent unauthorized return of the
lock bolt to the unlocked position. Thus, according to the invention, the latch device
is maintained, in the state in which it latches the second follower 20, with the same
degree of safety by which the lock bolt is maintained in its own locked position.
[0047] From the state shown in Fig. 6, the lock device is returned to the state shown in
Fig. 1 by returning the blocking member 62 to the release position by means of the
first follower and then by manoeuvring the third follower 30 such that the bolt coupling
members 50 and the lock bolt 40 return to their locked positions. During this return
movement, the compression spring 91 presses the second movable latch member 90 forwards,
and the latching end 93 disengages from the latching recess 76 on the rack element.
The driving end 92 of the second movable latch member also returns the first movable
latch member 87 in the clockwise direction to the starting position shown in Fig.
1. Thereafter, it is once again possible to use the second follower 20, and a thumb
turn coupled to the latter, in order to manoeuvre the blocking element 62.
[0048] Illustrative embodiments of the invention have been described above. The invention
is not limited to these embodiments and can be freely varied within the scope of the
attached patent claims. The lock can constitute or form part of a so-called single-point
lock having one or more bolts accommodated in the lock housing, or of a so-called
multi-point lock having one or more bolts arranged outside the lock housing. For example,
the hooks arranged on the coupling member for connection to bolt rods in an espagnolette
can be omitted. In this case, the lock can comprise one or more bolts or dead bolts
arranged in the lock housing. Regardless of whether the lock is designed to be connected
to an espagnolette or not, the bolts or dead bolts forming part of the lock can be
of different types and configurations. Examples of such bolts are turning bolts or
swing bolts, rectilinearly movable bolts, hook bolts, mushroom bolts and spring bolts.
Although the second follower has been described above as a thumb turn follower, it
is possible for this follower to be coupled to some other type of manually or electrically
driven manoeuvring member. Examples of such manoeuvring members are lock cylinders,
handles, electric motors, solenoids and similar devices designed to drive the second
follower. In other embodiments not shown here, the first and/or the second follower
can be designed to drive the movement of the lock bolt between the locked position
and unlocked position thereof. The blocking member can be designed in a number of
different ways and, instead of being configured as a separate movable member, can
for example form part of the coupling members between the first and/or second follower
for manoeuvring the movement of the lock bolt.
