[0001] This invention relates to locking apparatus and to a method of use thereof.
[0002] Although the following description refers almost exclusively to locking apparatus
for a door handle, it will be appreciated by persons skilled in the art that the locking
apparatus could be used on any handle or knob on any door, window or any structure
and/or item as required.
[0003] The Applicants already have a pending patent application
WO2016/128715 relating to locking apparatus for locking a handle spindle of a door or window in
use. Locking of the handle spindle increases the security of the handle mechanism
and makes it difficult for an unauthorised person to manipulate the spindle to gain
access through the door or window on which the locking apparatus provided. The locking
apparatus includes a slidable spindle locking plate movable relative to a handle frame
and/or spindle in use between a spindle locking position, wherein rotation of the
spindle is prevented or substantially prevented in use, and a spindle release position,
wherein the spindle is capable of rotation in use. User actuation means for actuating
movement of the spindle locking plate between the spindle locking position and the
spindle release position is provided. The locking plate is provided with a spindle
location aperture for location of the spindle therethrough in use. The spindle location
aperture has a first portion corresponding to the spindle locking position and at
least a second portion corresponding to the spindle release position. The spindle
location aperture is arranged such that the spindle is retainable within the spindle
locking aperture in both the spindle locking position and the spindle release position
in use.
[0004] One of the applications of use of the abovementioned invention is with a door handle
arrangement wherein movement of the door handle in use moves one, and typically a
plurality, of door lock arms or shoot bolts between locked and unlocked positions.
In the locked position, the shoot bolts are moved to a relatively outwardly protruding
position from one or more sides and/or ends of the door and are able to locate in
corresponding shoot bolt housings on the door frame to lock the door in a closed position
in use. In the unlocked position, the shoot bolts are moved to a relatively recessed
position, wherein the shoot bolts are moved clear of the corresponding shoot bolt
housings to allow the door to be opened in use. A five lever mortice deadlock is an
example of such a lock where the locking plate of
WO2016/128715 can be used. However, a problem associated with the above mechanism is that it is
possible for a user to move the spindle locking plate using the actuation means between
the spindle locking position and the spindle release position without the user having
actuated the lock arms/shoot bolts of the door handle mechanism. Thus, a user may
apply the spindle locking plate in the spindle locking position on their door handle
thinking they are securely locking their door, without having properly actuated the
multipoint locking arms/shoot bolts of the door handle.
[0005] It is therefore an aim of the present invention to provide locking apparatus that
overcomes the abovementioned problem.
[0006] It is a further aim of the present invention to provide a method of using locking
apparatus that overcomes the abovementioned problem.
[0007] According to a first aspect of the present invention there is provided locking apparatus,
said locking apparatus including:
handle means arranged such that movement of the handle means in a first direction,
within a first range of movement and/or to a first position actuates movement of one
or more bolt means from an unlocked position to a locked position in use;
spindle means provided in or associated with said handle means;
a spindle locking means movable relative to the spindle means in use between a spindle
locking position, wherein rotation of the spindle means is prevented or substantially
prevented, and a spindle release position, wherein the spindle means is capable of
rotation;
characterised in that the locking apparatus includes a security lock mechanism for
preventing the spindle locking means from being moved from the spindle release position
to the spindle locking position without the bolt means being in the locked position
and/or the handle means being in the first position, being moved in the first direction
and/or being moved within a first range of movement.
[0008] Thus, the present invention provides a lock security mechanism which ensures a user
has to move the bolt means (via the handle means) to the locked position before they
can lock the spindle means using the spindle locking means. This prevents a user from
inadvertently locking the spindle means without first actuating the door bolts and
securing the door, window or other item on which the locking apparatus is used. This
significantly enhances the security of the door, window or other item on which the
locking apparatus is provided in use.
[0009] Preferably the security locking mechanism is in a locked or blocked position unless
the handle means is moved to the first position, is moved in the first direction and/or
is moved within the first range of movement and/or the bolt means are in the locked
position.
[0010] Preferably the security locking mechanism is movable to an unblocked or release position
when the bolt means are in the locked position and/or the handle is moved in the first

frame, and/or other item on which the locking apparatus is used. With the bolt means
in the unlocked position, the bolt means are in a relatively recessed position with
respect to the lock apparatus, door, window, frame and/or other item on which the
locking apparatus is used.
[0014] In one embodiment the handle means must be moved from a position where the bolt means
are in the unlocked position to a position wherein the bolt means are in the locked
position, before the spindle locking member is movable from the spindle release position
to the spindle locking position.
[0015] In one embodiment the handle means are rotatably and/or pivotally mounted, or are
arranged to undergo rotation and/or pivotal movement in order to move the bolt means
between the locked position and the unlocked position.
[0016] The handle means are arranged such that movement of the handle means in a first direction,
through a first range of movement and/or to a first position allows the bolt means
to be moved from the unlocked position to the locked position.
[0017] In one embodiment the handle means are arranged such that movement of the handle
means in at least a second direction, through at least a second range of movement
and/or to a second position allows the bolt means to be moved from the locked position

Application
GB1419771.9 having stop means provided a spaced distance apart along the longitudinal axis of
the spindle between the first and second ends of the spindle so as to prevent movement
or removal of the spindle in a direction parallel to the longitudinal axis of the
spindle. However, it will be appreciated that other types of spindles and/or stop
means could be used.
[0118] In the illustrations, the spindle 28 is elongate in form having a square cross section
(although the spindle could have any cross sectional shape). A first stop means in
the form of a peripheral protrusion 30 extends outwardly of the spindle body and is
provided towards the end of the spindle adjacent the handle frame 6. In this example,
the protrusion 30 is integrally formed with the spindle body. A second stop means
in the form of a resiliently biased spring clip 32 having an aperture defined therein
through which the spindle 28 is located and engages with in use. The spring clip 32
is provided towards the end of the spindle adjacent the opposite handle frame 6'.
Angled teeth 34 provided on an external surface of the spindle 28 ensure the clip
32 can be moved in one direction only along the spindle 28. Once the spindle is fitted
to the handles 12 of the handle frames 6, 6', the stop means 30, 32 prevent the spindle
from being removed from the handle frames or handles 12.
[0119] In accordance with the applicant's co-pending patent application
WO2016/128715, the entire content of which is incorporated herein by reference, a spindle locking
plate 36 is provided for preventing rotation of the spindle 28, and therefore preventing
rotation of the handle 12, when in a spindle locking position. Spindle locking plate
36 is slidably mounted to a rear side 38 of handle frame 6'. In particular, a cavity
is defined in rear side 38 of handle frame 6' and the spindle locking plate 36 is
slidably mounted within the cavity. A rear surface of the spindle locking plate 36
is flush with the rear edge surfaces of the handle frame when assembled so that the
handle frame can be fitted flush with the door 4 in use.
[0120] User actuation means are provided for allowing a user to actuate movement of the
spindle locking plate 36 between one of two pre-defined positions in use, a spindle
locking position, as shown in figure 3b, and a spindle release position (not shown).
The user actuation means includes a gripping portion in the form of a button 40 provided
on a front side of the interior handle frame 6' and an actuation portion in the form
of a screw 42. Button 40 is slidable between a raised position, wherein the button
is relatively closer to the top 18 of handle frame 6' and this corresponds to the
spindle release position, and a lowered position, wherein the button is relatively
further away from top 18 of handle frame 6' and this corresponds to the spindle locking
position, as shown by arrow 44, in figure 1.
[0121] Screw 42 is joined to a rear surface of button 40 and protrudes outwardly therefrom.
A slot (not shown) is defined in handle frame 6'. An aperture 46 is defined in spindle
locking plate 36. Screw 42 passes through the slot and through aperture 46. As such,
user actuated sliding movement of the button 40, moves spindle locking plate 36 in
a corresponding upwardly or downwardly direction.
[0122] Spindle locking plate 36 has a spindle location aperture defined therein through
which the spindle 28 is located in use. The spindle location aperture is in the shape
of a keyhole having a first upper portion 48 and a second lower portion 50.
[0123] The upper aperture portion 48 is of complementary shape to spindle 28 but is of slightly
larger dimensions than the external dimensions of spindle 28. This allows spindle
28 to be moved into and out of the aperture portion 48 but prevents rotation of spindle
28 when located in said portion.
[0124] The lower aperture portion 50 is of a different shape and dimensions to upper portion
aperture portion 48. In particular, lower aperture portion 50 is circular in shape
and has larger dimensions than the external dimensions of spindle 28. This allows
spindle 28 to be moved into and out of the aperture portion 50 and allows free rotation
of spindle 28 when located in said portion.
[0125] Thus, when the spindle locking plate 36 is moved into the spindle locking position,
rotation of the spindle 28 is prevented and therefore rotation of handle 12 is prevented.
When the spindle locking plate 36 is moved into the spindle release position, rotation
of the spindle 28 is allowed and therefore rotation of handle 12 is allowed.
[0126] It will be appreciated by the skilled reader that there are a number of different
ways in which the spindle locking plate can be provided but which allows the spindle
to be moved between a spindle locked position and a spindle release position. The
present invention is not limited to any particular arrangement of the spindle locking
plate.
[0127] Movement of the handle element 12 typically allows bolt means and/or latch means
associated with the handle means to be actuated in use. There are many different types
of bolt and latch arrangements that could be used with the lock apparatus and/or handle
means of the present invention. Figures 2a-2c illustrate some examples of conventional
latch and shoot bolt systems. In Figure 2a, there is shown a latch and bolt system
100 for location in the interior of a door. The system 100 includes a body portion
102 including an aperture 104 defined between a front and rear face thereof for the
location of a spindle of a handle therethrough in use. An aperture 106 is defined
in body portion 102 between front and rear faces thereof for the location of a key
cylinder therethrough in use. Rotation of a key in the key cylinder in use typically
actuates movement of a deadbolt 103 in use. A latch bolt 108 is provided which can
move between a latch engaged position, wherein the latch protrudes relatively outwardly
with respect to the body portion 102 and is engaged within a latch housing (not shown)
on an opposing frame member of the door, and a latch disengaged position, wherein
the latch is moved to relatively recessed position with respect to the body portion
102 and is moved clear of the latch housing. With the latch bolt 108 in a latch engaged
position, the door can be moved to or retained in a closed position within the door
frame in use. With the latch bolt 108 in a latch disengaged position, the door can
be moved to an open position with respect to the door frame in use.
[0128] The system 100 is also provided with an elongate drive rail 110 which can be used
to drive the movement of shoot bolts 112, 114 provided at a top and bottom of the
door respectively in use. The shoot bolts 112, 114 are movable between a locked position,
wherein the shoot bolts protrude relatively outwardly with respect to the system 100
and at least a free end of the shoot bolts locates in a bolt housing provided on the
opposing frame of the door to the shoot bolt, and an unlocked position, wherein the
shoot bolts are relatively recessed with respect to the system 100 to allow the shoot
bolt to be moved clear of the bolt housing. With the shoot bolts provided in the locked
position, the door is locked, and the door cannot be opened. With the shoot bolts
in the unlocked position, the door is unlocked and can be moved between open and closed
positions.
[0129] Pivotal movement of a handle element associated with the system 100 actuates a suitable
mechanism for moving the latch bolt 108 between the latch engaged position and the
latch disengaged position and the shoot bolts between the locked and unlocked positions.
In particular, if the illustrated lock and bolt mechanism 100 was incorporated into
the lock apparatus 102 of the present invention, the handle element 12 is in a rest
or starting position, as shown in figures 1, 3a and 3b. In this example, the handle
element is substantially horizontal when in the rest or starting position and/or is
substantially parallel to a top or base of the door when fitted. Pivotal movement
of the handle element 12 in a first upwardly direction or through a first range of
movement between the resting position and an uppermost handle position, as shown by
arrow 52, moves the shoot bolts 112, 114 between the unlocked and locked positions.
Pivotal movement of the handle element 12 in a second downwardly direction or through
a second range of movement between the resting position and a lowermost handle position,
as shown by arrow 54, moves the latch bolt 108 between the latch engaged position
and the latch disengaged position. The handle element is resiliently biased to the
rest or starting position, such that user release of the handle element 12 always
returns the handle to the rest or starting position. Pivotal movement of the handle
element from the first position to the second position moves the shoot bolts from
the locked position to the unlocked position.
[0130] Figures 2b and 2c show other latch and bolt system arrangements that could be used
with the lock apparatus of the present invention.
[0131] A problem has been encountered in certain lock arrangements in that the spindle locking
plate 36 can be moved between the spindle locked position and the spindle release
position, without the shoot bolts associated with the lock apparatus being moved to
the locked position. This reduces the security of the door. The present invention
provides a solution to this problem by providing a mechanism that ensures the spindle
locking member or plate 36 cannot be moved from the unlocked position to the locked
position, without the handle bolt means or shoot bolts 112, 114 being in a locked
position. This will act as a reminder to a user to actuate the bolt system associated
with the handle means first prior to locking the handle spindle in place.
[0132] In accordance with the present invention, and with reference to figures 4a-4c, the
end of the handle element 12 facing inwardly of the handle frame 6' towards the interior
cavity of the frame 6' is provided with a spindle location member 200 which is rotatably
mounted on an interior surface of frame 6'. The spindle location member 200 has an
aperture 202 defined therein for the location of at least part of an end of spindle
28 therethrough in use. Pivotal movement of the handle element 12 causes rotation
of spindle 28, which in turn causes rotation of spindle location member 200.
[0133] A channel 204 is defined on an outermost or peripheral edge 206 of spindle location
member 200. The channel 204 has a first end or stop 208 and a second end or stop 210,
the purpose of which will be explained in more detail below. At least the peripheral
edge 206 on which the channel is provided is curved or substantially curved in shape.
[0134] Blocking means in the form of a blocking member 212 is provided between the spindle
location member 200 and the spindle locking plate for blocking movement of the spindle
locking plate 36 in use without the handle element 12 being moved to the first uppermost
position corresponding to the shoot bolt lock position. The blocking member 212 is
slidably movable in a channel member 213 between a block position, as shown in figure
4a, and a release position, as shown in figure 4b.
[0135] The blocking member 212 in this example is an elongate arm member 223, which is substantially
linear in form with at least one portion 228 protruding outwardly from a side of the
arm member facing towards the spindle location member 200.
[0136] Referring to figure 5, there is illustrated an interior facing surface 219 of the
spindle locking plate 36 that faces the interior of the handle frame 6' in use. The
exterior facing surface 221 of the spindle locking member 36 can be seen in figures
6a and 6b.
[0137] The spindle locking plate 36 has an upper portion 214 in which aperture 46 is defined.
Screw 42 is located through the same in use, such that movement of the user actuation
button 40 in a direction corresponding to arrow 44 in figure 1 causes the locking
plate 36 to slide between the spindle locking position and the spindle release position.
[0138] Spindle locking plate 36 has tracks 216 adjacent each peripheral edge 217 thereof
which are slidably mounted with protrusions 219 provided on the side edges of the
handle frame 6'. A sprung detent 223 is provided on locking plate 36 which moves between
two pre-defined detent locations 225, 227 provided on protrusion 29 on movement of
the spindle locking plate 36. When the detent 223 is located in detent location 225,
the spindle locking plate 36 is in a spindle release position. When the detent 223
is located in detent location 227, the spindle locking plate is in a spindle locking
position. The application of user force to actuation button 40 in a direction shown
by arrow 44 is sufficient to release the sprung detent 223 from one of the detent
location positions.
[0139] A recessed compartment 218 is defined between the spindle location aperture 229 and
aperture 46 on spindle locking plate 36. The recessed compartment 218 prevents obstruction
of plate 36 with blocking member 212 as it moves relative to frame 6' in use.
[0140] The axis of movement of spindle locking plate 36 is shown by arrow 220 and, in this
example, is parallel to a longitudinal axis of handle frame 6'. The axis of movement
of blocking member 212 relative to locking plate 36 in use, as shown by arrow 222,
is perpendicular to the axis of movement of the spindle locking plate 36, and to the
longitudinal axis of handle frame 6'.
[0141] As can be seen in figure 4a, with the blocking member 212 in the block position,
a free end 224 of the blocking member is located across a track 216 of the spindle
locking plate 36 and engages in a recess 215 on frame 6', thereby preventing movement
of the spindle locking plate 36 from the spindle release position to the spindle locking
position. As can be seen in figure 4b, with the blocking member 212 in the release
position, the free end 224 of the blocking member is moved clear of track 216 and
recess 215 on frame 6', thereby allowing movement of the spindle locking plate 36
to the spindle locking position, if required.
[0142] Blocking member 212 is provided with a protruding portion 228 protruding outwardly
from a side of the blocking member adjacent end 226 (opposite to free end 224). This
protruding portion 228 is slidably located in channel 204 of the spindle location
member 200.
[0143] With the handle means in a rest or start position, as shown in figure 4c, the protruding
portion 228 of blocking member 212 is located midway of channel 204. As the spindle
location member 200 is rotated as a result of the handle element being moved from
the handle rest position to the first uppermost position, the second end 208 of channel
204 is moved into an abutting position against a side of the protruding portion 228
of the blocking member 212. Further rotation of the spindle location member 200, causes
the blocking member 212 to slide from the block position to the release position as
a result of the force applied by the end 208 on the protruding portion 228, as shown
by figure 4b. As the spindle location member 200 is rotated in the opposite direction
as a result of the handle element being moved from the rest or starting position to
the second lowermost position, the first end 210 of channel 204 is moved into an abutting
position against an opposite side of the protruding portion 228 of the blocking member
212. Further rotation of the spindle location member 202 towards the second lowermost
position, causes the blocking member 212 to slide from the release position to the
block position as a result of the force applied by the end 206 on the protruding portion
228, as shown by figure 4a.
[0144] Rotation of the spindle location member in the second direction, to the second position
or through the second range of movement does not typically result in movement of the
blocking member 212.
[0145] The embodiments shown above are for where the spindle locking plate 36 is actuated
manually by user actuation button 40. The mechanism is a mechanical method.
[0146] Referring to figures 7a-7c, there is illustrated an electrical method for automatically
moving the spindle locking plate between the spindle release position and the spindle
locking position on moving the shoot bolts associated with the locking apparatus between
an unlocked position and a locked position.
[0147] Referring to figure 7a, there is illustrated a front view of the handle frame 6'.
Visual indication means in the form of three LEDs; a red LED 300, a green LED 302,
and an amber LED 304 as provided to inform a user the status of the locking apparatus.
With the red LED 300 lit, this indicates the shoot bolts are in a locked position
and the spindle locking plate is in a spindle locking position. With the green LED
302 lit, this indicates the shoot bolts are in an unlocked position and the spindle
locking plate is in a spindle release position. With the amber LED 304 lit, this indicates
the shoot bolts are in a locked position but the spindle locking plate is still in
a spindle release position.
[0148] Referring to figures 7b-7c, there is illustrated a rear view of handle frame 6'.
A solenoid member (not shown) is provided between frame 6' and spindle locking plate
36 to allow movement of the spindle locking plate 36 between the spindle locking position
and the spindle release position. Movement of the spindle locking plate 36 occurs
automatically on detection of whether the shoot bolts are in the locked or unlocked
positions. For example, in figure 7b, the solenoid member has moved spindle locking
plate 36 to a spindle release position as the shoot bolts are in an unlocked position.
In figure 7c, the solenoid member has moved spindle locking plate 36 to a spindle
locked position as the shoot bolts are in a locked position. Detection means can be
provided to detect the positon of the shoot bolts (i.e. in the locked or unlocked
positions).
[0149] Batteries 306 are provided in the handle frame 6' to power the solenoid member.
[0150] Figures 8a-8b show an alternative arrangement for providing second stop means on
the spindle 28. In this embodiment the second stop means are in the form of two grub
screws 308 which engage either side of spindle 28 to prevent movement of the spindle
in a direction parallel to the longitudinal axis of spindle 28 in use. Apertures 310
are defined in handle 212 to allow the grub screws 308 to be located therethrough
and engage with the part of the spindle 28 located in the handle 212.
[0151] This arrangement removes the requirement for teeth to be provided on spindle 28 or
for the resilient clip to be provided.
