NZ 786893 A Door Furniture Set for Mounting to a Door, and a Lockset including the Door Furniture Set Technical Field This invention generally s to a door furniture set for use with a bolt assembly when installed on door, and a lockset including the door furniture. More specifically the door furniture set is of the kind that includes a d actuator that is operable to adjust the condition of a coupling mechanism so in use to control interaction between a door lever and the latchbolt assembly. The door furniture has a ular application when used with a type of security screen door that is used in conjunction with a residential exit door, and it will be convenient to hereinafter describe the invention with reference to this particular application. It should be appreciated however that the invention is not d to residential security applications only.

Background of Invention A security screen door may take many forms and one form includes a metal frame boarder with metal grid within the r and a fly wire or security mesh screen y. The elements of the frame r and grid are generally made from hollow sections that are welded together. This form of security screen door is popular in the residential market and is normally used in conjunction with a lockable exit door to provide an extra layer of security. One benefit of the fly wire/security mesh is that it allows the occupant to see through the security screen door panel, and therefore it is desirable that the elements of the frame boarder and grid be sized to minimise visual impediment.

The security screen door and the exit door will need to be hung from the same door jamb, and the applicant is perceiving greater re on architects to design residential accommodation with door jambs having a slim line appearance.

Hanging both doors on a slim line door jamb will leave little space between the security screen door and exit door for the respective door furniture for each of those doors. This in turn applies pressure to the applicant to design door furniture that can function in limited space.

The security screen door will generally be fitted with a bolt assembly, often a mortice latchbolt assembly, while door furniture is mounted to the inner and outer surface of the security screen door. The combination of the door furniture and the mortice latchbolt is referred to as a lockset. The door furniture will include a pair of bodies, or escutcheons, positioned on either side of the door having door levers that are rotatable to adjust the olt assembly. The mortice latchbolt assembly can include a lock mechanism within its housing, which is controlled by a cylinder lock assembly extending through the housing, or a snib lever mounted with the inner door furniture. The snib lever will generally locate proud of the body mounted to the inner side of the door, while the cylinder lock often extends proud of both the bodies d to the inner and outer side of the door. While this arrangement of the cylinder lock relative to the bodies is driven by function of the rs in in cylinder lock, the applicant has appreciated that the consumers are looking for a cleaner appearance for their door furniture.

While the security industry has a range of electronically controlled products, these have tended to be in the high ty commercial applications. The design parameters for commercial applications tend to be more focussed on projecting an overt appearance of robustness. This can include large door furniture where the size of the bodies is not a limiting factor on the design of the components that fit within each body. However commercial applications are not particularly suitable where slim lines and cleaner appearances are preferred.

Consumers in general are growing more interested in electronic technology and are sted, or at least open to consider, applying the electronic logy for their security solutions in residential accommodation. The ant has iated that it might be desirable to provide electronic options for residential security applications.

A reference herein to a patent document or other matter which is given as prior art is not to be taken as an admission that that document or matter was, in Australia, known or that the information it ns was part of the common general knowledge as at the priority date of any of the claims.

According to another aspect of this ion there is provided a lockset including a latchbolt assembly and door furniture two lock assemblies as herein before Brief Description of Drawings The invention will now be described in r detail by reference to the accompanying drawings. It is to be understood that the particularity of the gs does not supersede the generality of the preceding description of the invention. is an isometric view of a lockset according to one aspect of this invention. is an exploded isometric view of part of a door furniture set for mounting to an outer side of a door according to another aspect of this invention. is the part of the door ure set from from a e perspective. is a front elevation view of the part of the door furniture set from with part of the body removed and the handle shown in broken line. is a rear elevation view of the part of the door furniture set from . is a rear isometric view of a coupling mechanism forming part of the door ure set. is a front elevation view of the coupling ism from . is an exploded isometric view of the coupling mechanism from . is a part sectional view of a coupling mechanism from showing the coupling mechanism in a coupled condition. is the coupling mechanism from with the cam member partially rotated. is the coupling mechanism from with the cam member fully rotated to show the coupling mechanism in a decoupled condition. is a flow chart for the powered control mechanism.

Detailed Description illustrates the isometric view of a lockset 1 which includes the combination of inner door furniture 2, outer door furniture 3 and a mortice latchbolt assembly 4. also illustrates a door 5 shown in dashed line, and for the purpose of this description the inner door furniture 2 is mounted to an inner side of the door 5 and the outer door furniture 3 is mounted to an outer side of the door 5, whilst the mortice latchbolt ly 4 is mounted to an edge of the door 5. More specifically the inner door furniture 2 es an inner body 6 for mounting to an inner side of the door , whilst the outer door furniture 3 includes an outer body 7 for mounting to an outer side of the door 5. rmore, the inner door ure 2 includes an inner handle 8 and the outer door furniture 3 includes an outer handle 9, each of which are independently ble about an actuation axis X-X (see ). Whilst the Figures illustrate an inner handle 8 and an outer handle 9, the door furniture the subject of the invention may also be used with turn knobs or other forms of hand operable members.

The function of the inner handle 8 and outer handle 9 is to interact with the latchbolt assembly 4, and in particular cause to move the bolt 10 which is rated in in an ed position relative to a housing 11 of the latchbolt assembly 4. It ought to be iated from that the inner body 6 and the outer body 7 are a relatively elongate slim line design with only a small slot 12 in the outer body giving an overall clean minimalist appearance.

Referring now to which illustrates the outer door furniture 3 which is substantially similar to the inner door ure 2 with exceptions of a number of functions that will be explained throughout the specification. The outer body 7 es the ation of a backing plate 13, a housing 14 and a cover 15. The cover 15 is attached to the housing 14 by way of a plurality of screws (generally identified as 16) so as to capture an outer user interface 17 and an outer control circuit 18 therebetween.

The function of the outer user interface 17 and the outer control circuit 18 would be described in greater detail by reference to latter illustrations. also illustrates the cover 15 including an re 19 and the housing 14 also including aperture 20 which are both coaxial with the actuation axis X-X and designed to accommodate one end of the outer door handle 9. Referring briefly now to FIG 2B, when the outer door furniture 3 is assembled, a boss 21 and washer 22 are fitted over the one end of the outer handle 9. A cam block 23 is attached to the one end of the outer handle 9 by a pair of screws 24 so that the cam block 23 is rotatable with the outer handle 9. The cam block 23 is positioned between an upper bumper 25 and a lower bumper 26 which are each bias towards the cam block by a plurality of springs 27a and 27b. Th e shape of the cam block 23 is configured to cause interaction bumpers 25, 26 so as to urge the outer handle 9 to adopt a perpendicular orientation relative to the outer body 7 (as seen in . In the event the outer handle 9 is rotated, the cam block 23 will urge the bumpers 25, 26 apart t the influence of the springs 27a, 27b. When the outer handle 9 is released, the bumpers 25, 26 will urge on the cam block 23 to return it to the perpendicular position. It should also be noted that the handing of the outer door furniture 3 can be adjusted by detaching the cam block 23 from the outer door handle 9, thereby allowing the outer door handle 9 to rotate through 180º before the cam block 23 is re-attached.

Referring again now to which illustrates a coupling mechanism 28 which is to be ed to the housing 14 by way of a ity of screws (generally identified as 29). It ought to be appreciated from FIGS. 2A and 3A that the coupling mechanism 28 includes a drive member 30 that is associated with the outer handle 9 whilst FIGS. 2B and 3B illustrate a driven member 31 which interact with a spindle (not shown) for interaction with the bolt 10. It ought to be appreciated that both the inner door furniture 2 and the outer door furniture 3 interact with the bolt 10 by way of their own independent spindle (not shown) located in the socket of the driven member 31.

It should also be noted from FIGS. 2A and 2B that the outer door furniture 3 includes a wiring loom 32 (shown adjacent the coupling ism 28) that ts the outer user interface 17 with the outer control circuit 18 so as to allow communication and power transfer therebetween. A main wiring loom 33 is illustrated extending from the outer control circuit 18 which is adapted to project out a rear of the backing plate 13 (see ) which in use connects with an equivalent main wiring loom extending from the inner door furniture 2 so as to allow for the transfer of power and communication between the outer control t 18 and a r inner control circuit within the inner door furniture. This interconnection is illustrated the flow chart of FIG. illustrates one manner in which the outer door furniture 3 is different to the inner door furniture 2 in that it includes a plug 34 that can be removed to e access to an auxiliary power terminal 35 to supply auxiliary power to the outer control circuit 18. Whilst the primary power supply is to come from a plurality of batteries, referred to in the flow chart in housed within the inner door furniture 2, the auxiliary power terminal 35 allow for ary power to be supplied to the outer control t 18 from an outer side of the door in the event that the primary power supply has failed.

Referring generally now to FIGS. 4A, 4B and 4C which illustrate the coupling mechanism 28. The coupling mechanism 28 includes a casing 36 which it can be appreciated from FIG 4C is formed by a cover 37 and a base 38 so as to house the drive member 30 and driven member 31 therein. The base 38 es an aperture 39 through which the drive member 30 extends, and is free to rotate about the actuation axis X-X. The cover 37 also includes an aperture 40 therein through which the driven member 31 extends for rotation about the actuation axis X-X. However, the re 40 in the cover 37 is adapted along with the driven member 31 to limit movement of the driven member 31 relative to the cover 37 h no more than 45º. The aperture 40 is defined in part by a pair of shoulders 41A, 41B which are engaged by a pair of stops 42 (only one of which is visible) of the driven member 31 so as to limit that rotational movement. also illustrates a cam member 43 shaped as a ring that is also rotatable about the actuation axis X-X. The cam member 43 includes a first cam surface 44 which faces radially inward towards the actuation axis XX for interaction with a detent 45. The interaction of the cam member 43 with the detent 45 will be bed with reference to FIGS. 5A to 5C later in the specification. However, it ought to be appreciated from that the detent 45 illustrated includes a floating member 46 and a captured member 47 which is biased under the influence of a spring 48 towards the actuation axis X-X. The spring 48 is captured by the drive member 30 so as to urge the captured member 47 s the actuation axis whilst allowing the captured member 47 to rotate with the drive member 30.

The coupling ism 28 illustrated in includes a motor 49, which drives a gear train 50 for rotating a worm gear 51, however other forms of powered actuators may be le. The cam member 43 is formed with a ring gear 52 on a radially outer surface thereof, around the entire ference of the ring, so that on activation of the motor 49 the worm gear 51 will interact with the ring gear 52 to cause rotation of the cam member 43. also illustrates the coupling mechanism being formed with a cam follower 53. The base 38 is formed with a shaft 54 ting therefrom for location in a socket 55 formed in the cam follower 53. The cam member 43 is formed with a second cam surface on a lateral surface of the cam member 43, (which is obscured in the illustrations) for engagement by an upper end of the cam follower 53. A lower end of the cam follower 53 interacts with a sensor 56 (see , and ) forming part of the outer control circuit 18. The interaction between the cam follower 53 and the sensor 56 communicates to the outer control circuit 18 the relative orientation of the cam member 43.

Referring now to which rates the cam member 43 in a first position which corresponds to the ng mechanism 28 in a coupled condition, whereby rotation of the outer handle 9 will result in rotation of the driven member 31. It ought to be appreciated from that the floating member 46 is located within a bore formed in the driven member 31, and with the orientation of the cam member 43 as rated, the first cam surface 44 s the floating member 46 across a shear line n the drive member 30 and the driven member 31. Furthermore, the captured member 47 extends across the shear line to locate within a notch 57 in the driven member. This arrangement allows for the transfer of torque between the drive member 30 and the driven member 31.

Referring now to which illustrates the cam member 43 having been partially rotated in the clockwise direction on activation of the motor 49 (see ), so as to allow the floating member 46 to move below the shear line between the drive member 30 and the driven member 31. Furthermore, the captured member 47, under the influence of the spring 48, retracts from the notch 57. Further rotation of the cam member 43 as illustrated in s in the cam member 43 adopting a second position. The rotation of the cam member 43 between the first position and the second position is rated as no more than 90º, however this may vary. When the cam member 43 is in the second position the coupling mechanism 28 is considered to be in a de-coupled condition, so that on of the outer handle 9 results in rotation of the drive member 30, but not rotation of the driven member 31.

It ought to be iated from that with the cam member 43 in the second position, the cam follower 53 is also in the second position relative to the sensor 56. The sensor is able to send a signal to the outer control circuit 18 to nect the power from the motor 49. In the event that power is supplied again to the motor 49 so as to return the cam member 43 to the first position, the lower end of the cam follower 43 would be adjusted slightly to the left from the position as illustrated in , and again trigger the sensor once the cam follower 53 reaches the first position. When the cam follower 53 is in the first position the sensor 56 will again indicate to the outer control circuit 18 to cut the supply of power to the motor 49.

Whilst the powered control mechanism, and in particular the adjustment of the coupling ism 28 within the outer body 7 has been described with reference to FIGS. 2 to 5, it ought to be appreciated that powered control mechanism can adjust the inner coupling 20 in the same manner. The powered control mechanism can receive user inputs or the outer user interface 17, or from a user interface within the inner body 6, to adjust either or both the coupling mechanism 26 within the inner body 6 and or outer body 7, as the main wiring loom 33 connects both the outer door ure 3 with the inner door furniture 2.the d control mechanism with both the inner powered or and the outer powered actuator.

The user inputs will generally include user credentials for identifying the user.

Where the user interface is in the form of a keypad, this may include a ed combination of numbers or letters that have been predefined to identify the user.

Alternatively, the where user interface is a magnetic or electronic access card the signal is supplied to the user interface magnetically or electronically to identify the user. Where the user interface includes a biometric reader, the user can use a fingerprint or the like to provide predefined user credentials. Clearly other forms of supplying user credentials, without using a mechanical key, are possible.

The user inputs also ably include user selections for selecting the mode adopted by the powered control mechanism shown in the flow chart in The control mechanism can operate in an access mode whereby at least the outer handle 9 is rendered operable for moving the bolt 10. The control mechanism can also operate in a secure mode whereby the outer handle 9 and the inner handle 8 are each rendered inoperable for moving the bolt 10. The secure mode effectively "deadlocks" the lockset 1 and it can be selected at either the user interface on the inner body 6 or outer body 7. The powered control mechanism can also operate in a passage mode whereby both the outer handle 9 and the inner handle 8 are rendered le to move the bolt 10. The powered l mechanism can also operate in an escape mode whereby at least the inner handle 8 is rendered operable to move the bolt 10. The powered control mechanism can also operate in a privacy mode whereby the outer handle 9 is rendered inoperable and the inner handle 8 is rendered operable for moving the bolt 10. The privacy mode may be selected from the user interface on the inner body 6 and render the outer user interface 17 inoperable, thereby providing the user in the inside with "privacy". The powered control mechanism can also operate in a safety mode whereby after a period of time the outer handle 9 is rendered inoperable, while the inner handle 8 is rendered operable for moving the bolt.

These user selections may be limited depending upon the user credentials received by the user interface. Furthermore, the user tials may fy a user ised to perform maintenance on the lockset 1, and so once identified the user selection can include a nance user input so as to collect information on the performance of the lockset 1 from the main PCB (see . Still furthermore the user credentials may identify a user as a master controller authorised to have master control over the lockset 1, and so once identified the user selection can e a master user input so as to override existing programming for the lockset 1 and reprogram the t 1 or more particularly the control circuit. The master user for example can set the mode for adoption by the control mechanism in the event of the power supply failure condition occurring. atively, the user credentials may identify a user as a temporary user, and in which case the user has a limited time, and limited modes for operation of the powered l mechanism. A temporary user may for e be a person that requires temporary access to the building to perform some agreed function. The maintenance and master user inputs can be made while the lockset is installed.

It is preferred that a visual indicator such as a LED 58 (see for example) provide a unique indication of the user input selected. It is further preferred that the visual indicator 58 e an indication whether the user credentials have been accepted or rejected, particularly for the mode of operation selected by the user. The LED can illuminate in a range of colours to indicate whether the user credentials are accepted or rejected and may flash in a unique sequence to indicate the mode adopted by the control mechanism. y, other configurations for the visual indicator are possible.

It should also be appreciated that the powered control mechanism can l the mode of operation so as to adopt a preselected mode after a period of time, so that for example after the user inputs has caused passage mode, the lockset can return to escape or passage mode. This ection should be limited to adjustment by a master user only.

It ought to be appreciated from the foregoing that the arrangement of the components within the inner body and outer body allow for a relatively slim line door furniture. The ability to effectively deadlock to the lockset from the outer user interface is particularly unique.

While the invention has been bed in conjunction with a limited number of embodiments, it will be appreciated by those skilled in the art that many alternative, modifications and variations in light of the foregoing ption are possible.

Accordingly, the present invention is intended to embrace all such alternative, modifications and variations as may fall within the spirit and scope of the invention as disclosed.
