  • a lock assembly 10 in accordance with the present invention for mounting on a door 12, and which includes an exterior lockset 14, an interior lockset 16, a latch assembly 18, and a strike 20.
  • Exterior lockset 14 includes an exterior operator assembly 22, a credential reader 24, and an exterior escutcheon 26. Exterior operator assembly 22 includes an exterior operator handle 28.
  • Interior lockset 16 includes an interior operator assembly 30, a control electronics module 32, an interior escutcheon 34, and a battery cover 36.
  • Interior operator assembly 30 includes an interior operator handle 38.
  • Control electronics module 32 is electrically connected to credential reader 24.

  • Within handle sleeve assembly 40 there is a chamber for mounting a motor drive assembly 44.
  • Motor drive assembly 44 is electrically connected to control electronics module 32 via wire conductors 45.
  • a spindle assembly 46 that includes an outer square spindle 48 within which there is rotatably received a locking spindle assembly 50.
  • a coupling mechanism 52 is provided to selectively drivably couple exterior operator assembly 22 to outer square spindle 48.
  • Locking spindle assembly 50 has a first end 50-1 that is mechanically coupled to a rotatable shaft of motor drive assembly 44.
  • Locking spindle assembly 50 is operably coupled to coupling mechanism 52 to selectively couple and decouple exterior operator assembly 22 to outer square spindle 48, with the normal, or rest, state being a decoupled state.
  • latch assembly 18 is configured with a bolt actuator mechanism 54 and a retractable bolt 56, as is customary in the art.
  • Bolt actuator mechanism 54 is operable by a rotation of outer square spindle 48 of spindle assembly 46 to retract bolt 56.
  • exterior operator handle 28, interior operator handle 38, motor drive assembly 44 and spindle assembly 46 are longitudinally aligned along an axis 58.
  • Interior lockset 16 is configured such that during normal operation interior operator handle 38 is always operatively coupled to spindle assembly 46, and in particular, to outer square spindle 48 via inside square drive spindle coupler 42, and in turn to latch assembly 18. As such, in normal operation a rotation of interior operator handle 38 always will result in a retraction of bolt 56. Also, in normal operation motor drive assembly 44 is always operatively coupled to locking spindle assembly 50.
  • exterior lockset 14 is configured such that exterior operator handle 28 is selectively coupled to latch assembly 18. In a locked condition, exterior operator handle 28 is decoupled from spindle assembly 46, and thus a rotation of exterior operator handle 28 does not result in a retraction of bolt 56. In an unlocked condition, exterior operator handle 28 is coupled to spindle assembly 46 via coupling mechanism 52 to operate latch assembly 18, and thus a rotation of exterior operator handle 28 will result in a retraction of bolt 56.
  • the unlocked condition may be achieved by providing a valid credential, e.g., an RFID card, to be read by credential reader 24, which in turn sends a signal to control electronics module 32.
  • Control electronics module 32 compares the read credential to a database of stored authorized credentials, and if a match is found, responds by operating motor drive assembly 44 to rotate the inner portion, i.e., locking spindle assembly 50, of spindle assembly 46 to activate coupling mechanism 52 to couple exterior operator handle 28 to latch assembly 18 via coupling mechanism 52 and outer square spindle 48 (see also Fig. 5 ).
  • exterior lockset 14 is provided with a mechanical override in the form of a key operated interchangeable keyed lock core 60 that is operatively coupled to coupling mechanism 52, such that a valid operator key may be used to effect a coupling of exterior operator handle 28 to latch assembly 18.
  • spindle assembly 46 includes the outer square spindle 48.
  • Outer square spindle 48 has a first end 48-1, a second end 48-2, and a longitudinal bore 48-3 that extends between first end 48-1 and second end 48-2.
  • Longitudinal bore 48-3 of outer square spindle 48 is sized to rotatably receive locking spindle assembly 50.
  • Second end 48-2 of outer square spindle 48 is configured to drivably connect to a body 52-1 of coupling mechanism 52.
  • Body 52-1 of coupling mechanism 52 includes a slot 52-2 and a longitudinal opening 52-3. Longitudinal opening 52-3 is co-axial with longitudinal bore 48-3 along axis 58. Slot 52-2 is arranged to perpendicularly intersect longitudinal opening 52-3. A slide member 52-4 is received in slot 52-2 in a sliding arrangement, such that slide member 52-4 is selectively extendable from body 52-1. Slide member 52-4 has a cam opening 52-5 and a coupling tab 52-6. Coupling tab 52-6 is configured to selectively engage a coupling portion 22-1 of exterior operator assembly 22, such that when so engaged, exterior operator handle 28 is rotatably coupled to outer square spindle 48 to operate latch assembly 18.
  • Locking spindle assembly 50 is a three piece elongate sub-assembly, generally round in cross-section, which transfers a torque function that is required to lock and unlock lock assembly 10 via the lifting and lowering of slide member 52-4 of coupling mechanism 52.

  • coupling end 64-1 of locking actuator spindle 64 is inserted through longitudinal opening 52-3 of body 52-1 of coupling mechanism 52, and through cam opening 52-5 of slide member 52-4. Head portion 64-4 serves as a stop to engage coupling mechanism 52 to position cam protrusion 64-3 in cam opening 52-5 of slide member 52-4. Coupling end 64-1 of locking actuator spindle 64 is then connected to U-shaped clip end 66-2 of locking spindle link 66. Coupling end 62-1 of locking spindle tail 62 is then connected to U-shaped clip end 66-1 of locking spindle link 66.
  • Locking spindle assembly 50 is then inserted, first end 50-1 first, through longitudinal bore 48-3 of outer square spindle 48, such that second end 48-2 of outer square spindle 48 drivably engages body 52-1 of coupling mechanism 52.

  • Housing 70 has an exterior shape including a plurality of flats 70-3 that corresponds to an interior shape of a mounting opening 38-1 in interior operator handle 38 to mount interior operator handle 38.
  • Housing 70 is hollow and includes a side wall 70-5 that defines a chamber 70-6 configured to receive and mount motor drive assembly 44.
  • a portion of chamber 70-6 at proximal end 70-1 is substantially rectangular to match the exterior profile of motor 72 so as to prevent a rotational movement of motor 72 relative to housing 70.
  • Proximal to distal end 70-2 there is formed a bore 70-7 in side wall 70-5 that is arranged perpendicular to axis 58, and is configured to slidably receive a sensor pin 73.
  • a sliding clip 70-8 is used to axially retain motor drive assembly 44 in chamber 70-6 of housing 70.
  • motor 72 is electrically connected to control electronics module 32 via the wire conductors 45.
  • Motor 72 includes a rotatable motor shaft 72-1 which is drivably connected to clutch assembly 74 and is rotatable about axis 58, and is coaxial with outer square spindle 48 and the locking spindle assembly 50.
  • Motor 72 may be, for example, a DC motor.
  • clutch assembly 74 includes a motor clutch base 76, a motor clutch driver 78, a motor clutch 80, a motor clutch compression spring 82, and a sensor cam 84.
  • Motor clutch base 76 has an opening 76-1 that is mounted, e.g., in a press fit, to motor shaft 72-1 of motor 72.
  • Motor clutch base 76 has a plurality of distal peripheral drive notches 76-2 located around the periphery of motor clutch base 76.
  • Motor clutch 80 includes a centre bore 80-1, a plurality of proximal peripheral tabs 80-2 located around the periphery of the motor clutch 80, a distal annular recess 80-3 and a pair of diametrically opposed cam surfaces 80-4.
  • the plurality of proximal peripheral tabs 80-2 is configured to be drivably received by the plurality of distal peripheral drive notches 76-2 of motor clutch base 76.
  • Motor clutch driver 78 includes an elongate shaft 78-1 having a drive opening 78-2 having drive flats, and is configured to drivably receive first end 50-1 of locking spindle tail 62 of locking spindle assembly 50 (see Figs. 5 and 7 ). As such, a rotation of motor clutch driver 78 results in a direct rotation of locking spindle assembly 50. Extending radially outward from elongate shaft 78-1 is a pair of diametrically opposed cam protrusions 78-3 configured to be drivably engaged with the diametrically opposed cam surfaces 80-4 of motor clutch 80. Motor clutch driver 78 further includes a pair of diametrically opposed distal drive tabs 78-4.

Opening 84-1 has a pair of diametrically opposed notches 84-2 configured to receive the pair of diametrically opposed distal drive tabs 78-4 of motor clutch driver 78.
  • Sensor cam 84 also includes a circumferential cam surface 84-3 which is engaged by sensor pin 73.
  • a rotational position of circumferential cam surface 84-3 of sensor cam 84 is dependent on a rotational position of locking spindle assembly 50.
  • sensor pin 73 is raised or lowered, which is indicative of the locking status of lock assembly 10.
  • sensor pin 73 is used to provide feedback to control electronics module 32 as to whether lock assembly 10 is in a locked or an unlocked state.
  • Motor clutch compression spring 82 is interposed between motor clutch 80 and sensor cam 84. More particularly, motor clutch compression spring 82 is received around elongate shaft 78-1 of motor clutch driver 78, and is fitted over distal annular recess 80-3 of motor clutch 80 to maintain the radial position of motor clutch compression spring 82.
  • direct axial rotation output from motor 72 of motor drive assembly 44 is used to drive locking spindle assembly 50 via clutch assembly 74, and in turn, to operatively drive coupling mechanism 52 (see Figs. 5-7 ) to effect locking and unlocking of lock assembly 10.
  • Motor drive assembly 44 and locking spindle assembly 50 extend from the non-keyed interior side of lock assembly 10 through door 12 to the keyed exterior side of lock assembly 10.
  • motor 72 can be mounted on the centre axis 58 of exterior operator handle 28 and interior operator assembly 30, and thus motor drive assembly 44 can therefore be mounted inside the handle sleeve assembly 40 of interior operator assembly 30, and accordingly, inside the mounting opening 38-1 of interior operator handle 38 on the non-keyed side of door 12.
  • motor 72 Since motor 72 is mounted inside of interior operator handle 38, every time that the lever of interior operator handle 38 is rotated clockwise or counterclockwise, motor 72 also rotates clockwise or counterclockwise along with the locking spindle assembly 50.
  • slide member 52-4 i.e., locking plate
  • coupling mechanism 52 is disengaged and does not rotate interior operator handle 38 or motor 72 on the non-keyed side of door 12.
  • slide member 52-4 i.e., locking plate, of coupling mechanism 52 is engaged, any rotation from the exterior operator handle 28 on the keyed side of door 12 will cause interior operator handle 38 and motor 72 on the non-keyed side of door 12 to also rotate.
  • Clutch assembly 74 of motor drive assembly 44 allows the output torque from motor 72 to be transmitted to the three piece locking spindle assembly 50, but also will clutch, i.e., slip, and will allow motor shaft 72-1 to spin freely if there is enough resistance from the slide member 52-4, i.e., locking plate, of coupling mechanism 52 in attempting to move slide member 52-4 into a locked or unlocked position.
