- the latch By having such an electromechanical locking mechanism, the latch will be pivotable to and from a locking configuration and a release configuration rather than being linearly displaceable. In this way, part of the weight of the latch will be supported by the pivot which will lessen the burden on the motor when transitioning the latch to and from a locked configuration and a release configuration. This will allow a smaller motor to be used, if desired, with a smaller power requirement and a lower cost. Furthermore, it is envisaged that by pivotally mounting the latch, the amount of movement required transitioning the latch to and from a locked configuration and a release configuration will be reduced thereby resulting in a lower power draw from the battery but without compromising functionality or requiring tighter manufacturing tolerances.

Inside the inner escutcheon 5 there is provided a battery PCB 54 having a battery 55 mounted thereon.
- the inner escutcheon 5 houses a mechanism chassis 56 on which the latch mechanism, indicated generally by the reference numeral 70, and described in greater detail below, is mounted.
- the mechanism chassis 56 also carries a latch pivot pin 57 which is secured in place on the mechanism chassis 56 by a pivot pin nut 58, a sensor PCB mount 59, a handle position sensor activator 60, a sensor PCB assembly 61 and a latch guide plate.
- An inner handle return spring 62 is positioned intermediate the inner spindle interlock 17 and the mechanism chassis 56 which provides an inner handle return spring stop.
- the inner handle return spring 62 is operable to return the inner handle 9 back to a substantially horizontal configuration such as that shown in Figures 1 to 6 inclusive.
- the inner escutcheon 5 houses an internal bearing 63 and a screw cap 64.

- the helical spring 76 is connected to the latch at a lower end thereof and the upper end of the helical spring 76 is connected to the wormscrew nut 74.
- the wormscrew nut 74 is prevented from rotating and therefore is moveable upwards and downwards in a reciprocal fashion along the wormscrew 73.
- the direction of travel of the wormscrew nut 74 along the wormscrew 73 will depend on the direction of rotation of the wormscrew 73.
- the latch 71 comprises an elongate body cranked intermediate its ends and having a throughbore 77 located adjacent one end thereof.

- FIG. 8 there is shown a perspective view of the electromechanical locking mechanism with the outer escutcheon housing 32 removed. The positioning of the outer handle return spring 42, the outer handle return spring stop 41 and the main PCB 34 are shown.
- the handle position sensor activator 60 comprises an arm 81 pivotably mounted about pivot point 82 intermediate its ends. A first, lower end 83 of the arm 81 is shown in contact with a protrusion 84 on the outer spindle interlock 15. A second, upper end 85 of the arm is shown in contact with a trigger switch 86.
- the lower end 83 of the arm 81 will be pushed outwards by the protrusion 84 on the outer spindle interlock 15 thereby causing the upper end 85 of the arm 81 to move inwardly and contact the trigger switch. This indicates that the door handle is in this position.
- the protrusion 84 on the outer spindle interlock 15 will move away from the lower end 83 of the arm 81.
- the spring force of the trigger switch 86 will push the upper end 85 of the arm 81 outwardly thereby indicating that the handle 9 has been turned and that the door is not locked.
- This information can be used in the control of the door. For example, if the door handle has not been depressed in a predetermined period of time after the electromechanical locking mechanism has been activated using an electronic key, the motor 72 may be operated once more to lock the door once more.
- FIGS. 11 to 15 inclusive there are shown views of the electromechanical locking mechanism with the outer escutcheon and most of the inner escutcheon removed.

- the outer spindle interlock is therefore free to rotate once the hand 89 of the latch 71 has been disengaged from the notch 91. If the outer handle (not shown) is operated, the handles, the inner and outer spindles and the inner and outer spindle interlocks will rotate thereby causing the outer spindle 11 to operate a door lock (not shown) and allowing the door to be opened.
- the motor 72 will be operated in the opposite orientation rotating the wormscrew 73 in the opposite sense.
- the wormscrew nut 74 will travel downwards on the wormscrew 73 thereby pushing the helical spring 76 and in turn the latch 71 downwards. If the latch 71 and the notch 91 have been realigned, the latch 71 will be seated once more in the notch 91, thereby preventing further rotation of the outer spindle interlock and the outer handle until a valid electronic key is presented once more to the electronic key reader.
- An optical sensor (not shown), is provided and detects a sensor tab 93 mounted on the wormscrew nut cover 75.
- the optical sensor and the sensor tab 93 work together to brake the system in both latch open and latch closed positions and also to stop the wormscrew nut 74 binding at the top of the wormscrew or running off at the bottom of the wormscrew.
- the wormscrew nut cover 75 moves with the wormscrew 74.
- the sensor tab will also be lowered on the wormscrew 73.
- the sensor tab 93 is detected by the optical sensor.
- the optical sensor When the sensor tab 93 reaches a certain lowermost point on the wormscrew, the optical sensor will detect the absence of the sensor tab and the motor 72 may be stopped from further operation in that orientation to prevent disengagement of the wormscrew nut 74 from the wormscrew 73.
- the optical sensor when the wormscrew is being operated in the opposite orientation and the sensor tab is moving upwards along the wormscrew, the optical sensor will, after a time, detect the absence of the sensor tab. This indicates that the sensor tab has moved above the optical sensor and the latch has been disengaged in which case and the motor 72 can be prevented from further operation in the present orientation to ensure that the wormscrew nut 74 does not bind at the top of the wormscrew. It will be understood that the motor is only temporarily prevented from operating in a particular orientation and can be reset once the optical sensor has detected the sensor tab 93 once more.
- FIG 15 there is shown a rear view of the locking mechanism shown in Figure 11 .
- the inner spindle interlock 17 also comprises a notch 97 in which the U-shaped cam surface 95 sits.
- the sides of the notch 97 are also chamfered into cam surfaces 99, 101 for complementary engagement of the U-shaped cam surface 95 of the latch, which will be described in more detail below.
- a feature of the electromechanical locking mechanism 1 is that the locking mechanism must be able to be released from the inside without the use of an electronic key. Instead, it is necessary to allow simple operation of the inner handle 9 to cause the door to open. This is necessary in cases of emergency. It can be seen from Figure 15 , that as the inner handle 9 is depressed, the inner spindle will begin to turn which will cause the inner spindle interlock 17 to rotate also. The inner spindle interlock 17 and the outer spindle interlock 15 are allowed a limited amount of rotation relative to each other to allow the inner spindle interlock 17 to rotate in this manner.
- FIG. 16 to 19 there are shown a plurality of views of the electromechanical locking mechanism similar to Figures 11 to 14 respectively but with the outer spindle interlock 15 removed. It can be seen from Figures 16 to 19 , that the only portion of the latch that engages the inner spindle interlock 17 is the cam surface 95 on the underside of the latch 71.
- FIG. 20 to 22 there are shown a plurality of views of the electromechanical locking mechanism similar to Figures 11 to 13 respectively but with the outer spindle, inner spindle interlock and inner handle removed. It can be seen from Figures 20 to 22 that the cam surface 95 extends from the end 87 to the downwardly depending hand 89 and that the only portion of the latch that engages the outer spindle interlock 17 is the downwardly depending hand 89.
- FIG 23 there is shown a side view of the latch 71 resting on the inner spindle interlock 17. Furthermore, the wormscrew nut cover 75 has been removed to shown the engagement of the wormscrew nut 74 and the helical spring 76. A helical channel is formed in the side of the wormscrew nut 74 to receive the helical spring.
- Figure 24 there is shown a side view similar to the view shown in Figure 23 without the wormscrew nut 74. It can be seen that the wormscrew 73 extends downwardly inside the helical spring.
- handles are not limiting and other types of handles could be used in their stead.
- a leaf spring, torsion spring or other spring could be used instead of the helical spring with appropriate modifications made to the engagement of the leaf spring, torsion spring or other spring and the wormscrew.
- the spring creates an 'elastic' connection between the pivot latch and the micro-motor/wormscrew assembly. It is envisaged that a non-elastic (i.e. rigid) connection would cause damage to a micro-motor very quickly in normal use.
- the spring acts as a shock absorber when the external handle/escutcheon is subjected to attack from an intruder. The spring suppresses pivot latch bounce and protects delicate electronic components such as the light sensor and the micro-motor. In the down (i.e. locked) position, the spring is slightly compressed providing a down force on the pivot latch. This force would not be there without the spring.
- the pivot latch hits a physical stop before the light sensor (optical sensor and sensor tab 93 arrangement) stops the motor. Therefore, after the pivot latch is stopped, the nut continues to travel a little more up the wormscrew until it reaches the stop position determined by the optical sensor. In that position, the spring will be slightly extended providing a small downward pulling force on the nut in preparation for closing after a fixed time. Fourth, the helical spring prevents the nut from rotating when the wormscrew rotates thus causing the nut to travel up and down the wormscrew.

Abstract
Description
- This invention relates to an electromechanical locking mechanism comprising an inner escutcheon, an outer escutcheon, an inner handle, an outer handle, an inner spindle, an outer spindle, an inner spindle interlock, an outer spindle interlock coupled to the inner spindle interlock, and an electronic key reader housed in the outer escutcheon.
- Electromechanical locking mechanisms are commonly used in hotels and other buildings on doors where it is desirable to provide a locking mechanism that requires an electronic key to open the door from the outside and only requires simple operation of the inner handle to open the door from the inside. These locking mechanisms provide a high level of security from intruders while at the same time permit fast evacuation in case of emergency.
- Generally speaking, these electromechanical locking mechanisms have a pair of spindles, an inner spindle connected to an inner handle and an outer spindle connected to an outer handle, that are either releasably engageable with each other by way of a clutch mechanism, or are connected to each other permanently and their movement may be selectively restricted by a latch. By and large, electromechanical locking mechanisms that incorporate a latch rather than a clutch mechanism are simpler in construction and are easier to manufacture. The present invention relates to an electromechanical locking mechanism of the type having a latch located in the inner escutcheon of the electromechanical locking mechanism. There are numerous advantages to placing the latch in the inner escutcheon. By having the latch located in the inner escutcheon of the door, the outer escutcheon can be more compact which is desirable aesthetically speaking. Furthermore, the electromechanical locking mechanism with the latch located in the inner escutcheon will be more secure as the latch will be less accessible to intruders.
- One such electromechanical locking mechanism is that described in European Patent No.
EP1130195 in the name of Salto Systems S.L. This patent describes a latch mechanism for electronic locks that has a latch located in the inner escutcheon. The latch releasably engages an outer spindle tumbler to control rotation of the outer and inner spindles. When actuated by an electronic key, the latch is linearly displaceable by a motor into and out of a groove formed in the outer spindle tumbler. - There are however problems with the known electromechanical locking mechanisms that incorporate a latch. Most importantly, these electromechanical locking mechanisms tend to be quite power hungry as the latch must be moved a substantial distance in order to make the transition to and from a locked configuration and a release configuration. This transition results in a significant draw on the battery power supply and a relatively short battery life. A short battery life will mean higher maintenance costs and equipment costs which is undesirable.
- In order to obviate the problem of short battery life, it is possible to provide larger batteries in the locking mechanism however this increases the size of the inner escutcheon and increases the cost of the electromechanical locking mechanism, both of which are undesirable. Another way to circumvent the problem of short battery life is to reduce the amount of linear displacement required by the latch. However, reducing the amount of linear displacement required leads to a locking mechanism that is more susceptible to manipulation by unscrupulous individuals. Reducing the amount of linear displacement required also results in a need for very tight manufacturing tolerances, without which operation of the locking mechanism will be unreliable.
- It is an object of the present invention to provide an electromechanical locking mechanism that overcomes at least some of the above-identified problems. It is a further object of the present invention to provide an electromechanical locking mechanism that is efficient in operation resulting in an extended battery life. It is a further still object of the invention to provide an electromechanical locking mechanism that provides a useful choice to the consumer.
- According to the invention there is provided an electromechanical locking mechanism comprising an inner escutcheon, an outer escutcheon, an inner handle, an outer handle, an inner spindle, an outer spindle, an inner spindle interlock, an outer spindle interlock coupled to the inner spindle interlock, an electronic key reader housed in the outer escutcheon, a latch mounted in the inner escutcheon and operable to releasably engage a notch in the outer spindle interlock and prevent rotation of the outer spindle interlock and the outer spindle when the latch is engaged in the notch, a battery-operated motor housed in the inner escutcheon, coupled to the latch and responsive to the electronic key reader to actuate the latch, the inner spindle interlock and the latch having complementary cam surfaces so that rotation of the inner spindle interlock caused by operation of the inner handle will result in disengagement of the latch from the notch, and in which the latch is pivotably mounted in the inner escutcheon and pivots to and from a locking configuration in which part of the latch is located in the notch thereby preventing rotation of the outer spindle interlock, and a release configuration in which the latch is free of the notch thereby allowing rotation of the outer spindle interlock.
- By having such an electromechanical locking mechanism, the latch will be pivotable to and from a locking configuration and a release configuration rather than being linearly displaceable. In this way, part of the weight of the latch will be supported by the pivot which will lessen the burden on the motor when transitioning the latch to and from a locked configuration and a release configuration. This will allow a smaller motor to be used, if desired, with a smaller power requirement and a lower cost. Furthermore, it is envisaged that by pivotally mounting the latch, the amount of movement required transitioning the latch to and from a locked configuration and a release configuration will be reduced thereby resulting in a lower power draw from the battery but without compromising functionality or requiring tighter manufacturing tolerances.
- In one embodiment of the invention there is provided an electromechanical locking mechanism in which the latch comprises an elongate arm, one end of which is dimensioned for reception in the notch and the other end of which is pivotably mounted on the inner escutcheon.
- In one embodiment of the invention there is provided an electromechanical locking mechanism in which the end of the latch pivotably mounted on the inner escutcheon is provided with a through hole for reception of a transverse mounting pin.
- In one embodiment of the invention there is provided an electromechanical locking mechanism in which the transverse mounting pin about which the latch pivots is arranged substantially orthogonal to the longitudinal axis of the inner spindle.
- In one embodiment of the invention there is provided an electromechanical locking mechanism in which the latch is cranked intermediate its ends.
- In one embodiment of the invention there is provided an electromechanical locking mechanism in which there is provided a notch in the inner spindle interlock, and in which at least portion of the latch sits in the notch in the inner spindle interlock when the latch is engaged in the notch in the outer spindle interlock. This is seen as a useful feature of the present invention as it will provide a locking mechanism that is compact in construction and reliable in operation.
- In one embodiment of the invention there is provided an electromechanical locking mechanism in which at least one of the side walls of the notch in the inner spindle interlock, and the underside of the portion of the latch that is arranged to sit in the notch in the inner spindle interlock, is chamfered. By chamfering either or preferably both of the side walls of the notch in the inner spindle interlock and the underside of the portion of the latch that periodically sits in the notch in the inner spindle interlock, a more reliable, smoother mechanism will be provided.
- In one embodiment of the invention there is provided an electromechanical locking mechanism in which there is provided a resiliently deformable coupling member coupling the motor to the latch. By providing a resiliently deformable coupling member intermediate the motor and the latch, the motor and the locking mechanism will be protected from known attacks consisting of repeated, rapid manipulation of the outer handle.
- In one embodiment of the invention there is provided an electromechanical locking mechanism in which the resiliently deformable coupling member comprises a helical spring. This is seen as a particularly preferred embodiment of the present invention. By having a helical spring, the movement of the motor can be translated into movement of the latch in a simple and straightforward manner that is simple and inexpensive to manufacture. The connection of the helical spring to the latch and the motor will be more secure than other known arrangements and will not be as prone to slippage or disengagement over time as is the case with some of the existing mechanisms. In addition to the foregoing, the helical spring will provide a more predictable performance.
- In one embodiment of the invention there is provided an electromechanical locking mechanism in which the motor comprises a wormscrew and a wormscrew nut for engagement of the resiliently deformable coupling member, the wormscrew nut being moveable in a reciprocal fashion back and forth along the wormscrew. Again, this is seen as a reliable way to connect the motor to the resiliently deformable coupling member, particularly if a helical spring is used.
- In one embodiment of the invention there is provided an electromechanical locking mechanism in which there is provided a sensor operable to detect the position of the wormscrew nut relative the wormscrew and to prevent disengagement of the wormscrew nut from the wormscrew.
- In one embodiment of the invention there is provided an electromechanical locking mechanism in which there is provided a wormscrew nut cover having a sensor tab extending outwardly therefrom.

Figure 7 , there is shown an exploded view of theelectromechanical locking mechanism 1. In addition to theouter escutcheon 3, theinner escutcheon 5, theouter handle 7, theinner handle 9 and theouter spindle 11, there is further provided aninner spindle 13 connected to theinner handle 9, anouter spindle interlock 15 mounted on the free end of theouter spindle 11, and aninner spindle interlock 17 mounted on the free end of the inner spindle. Theouter spindle interlock 15 is provided with an axialcylindrical protrusion 19 that in use is housed inside a complementaryaxial bore 21 in the inner spindle interlock. - The
outer escutcheon 3 comprises a multipart casing including an outer escutcheon backplate 31, anouter escutcheon housing 32 and an outer escutcheon cover 33 that are joined together to form the outer escutcheon casing. Inside theouter escutcheon 3 there is provided a main printed circuit board (PCB) 34 having an electronickey reader 35 thereon. Themain PCB 34 is further provided with an accessible universal serial bus (USB)port 36 that under normal operation is hidden behind theUSB cover 37. The outer escutcheon also houses aspindle sizer 38 which has aninternal bore 39 dimensioned to form a snug fit around theouter spindle 11. Thespindle sizer 39 sits in an outerhandle return tumbler 40, which in turn is mounted in an outer handlereturn spring stop 41. Anouter return spring 42 is fitted intermediate the outerhandle return tumbler 40 and the outer handlereturn spring stop 41 and is operable to return theouter handle 7 back to a substantially horizontal configuration such as that shown inFigures 1 to 6 inclusive. A Euro-cylinder lock protector 43 is provided if needed. Alternatively, a suitable insert (not shown) could be provided if thelock protector 43 is not required. A pair of LED light guides 44, 45 is provided for thePCB 34. - The
inner escutcheon 5 also comprises a multipart casing including an inner escutcheon backplate 51, aninner escutcheon housing 52 and aninner escutcheon cover 53 that are joined together to form the inner escutcheon casing. Inside theinner escutcheon 5 there is provided abattery PCB 54 having abattery 55 mounted thereon. Theinner escutcheon 5 houses amechanism chassis 56 on which the latch mechanism, indicated generally by the reference numeral 70, and described in greater detail below, is mounted. Themechanism chassis 56 also carries alatch pivot pin 57 which is secured in place on themechanism chassis 56 by apivot pin nut 58, asensor PCB mount 59, a handleposition sensor activator 60, asensor PCB assembly 61 and a latch guide plate. An innerhandle return spring 62 is positioned intermediate theinner spindle interlock 17 and themechanism chassis 56 which provides an inner handle return spring stop. The innerhandle return spring 62 is operable to return theinner handle 9 back to a substantially horizontal configuration such as that shown inFigures 1 to 6 inclusive. Theinner escutcheon 5 houses aninternal bearing 63 and ascrew cap 64. - The latch mechanism 70 comprises a
latch 71, amotor 72 having awormscrew 73, awormscrew nut 74, awormscrew nut cover 75 and a resiliently deformable coupling member, provided by way of ahelical spring 76, coupling themotor 72 to thelatch 71. Thehelical spring 76 is connected to the latch at a lower end thereof and the upper end of thehelical spring 76 is connected to thewormscrew nut 74. Thewormscrew nut 74 is prevented from rotating and therefore is moveable upwards and downwards in a reciprocal fashion along thewormscrew 73. The direction of travel of thewormscrew nut 74 along thewormscrew 73 will depend on the direction of rotation of thewormscrew 73. - The
latch 71 comprises an elongate body cranked intermediate its ends and having a throughbore 77 located adjacent one end thereof. Thepivot pin 57 passes through an aperture in the mechanism chassis, through thethroughbore 77 and through a second aperture in the mechanism chassis before being secured in place by apivot pin nut 58. Thepivot pin 57 forms a close fit in thethroughbore 77 to limit play from side to side of thelatch 71. The operation of the electromechanical locking mechanism will be understood from the following detailed description ofFigures 8 to 24 . - Referring now to
Figure 8 , there is shown a perspective view of the electromechanical locking mechanism with theouter escutcheon housing 32 removed. The positioning of the outerhandle return spring 42, the outer handlereturn spring stop 41 and themain PCB 34 are shown. - Referring to
Figures 9 and10 , there are shown views of the locking mechanism according to the invention with the outer escutcheon and most of the inner escutcheon removed. Referring specifically toFigure 10 , the handleposition sensor activator 60 is shown. The handleposition sensor activator 60 comprises anarm 81 pivotably mounted aboutpivot point 82 intermediate its ends. A first,lower end 83 of thearm 81 is shown in contact with aprotrusion 84 on theouter spindle interlock 15. A second,upper end 85 of the arm is shown in contact with atrigger switch 86. In use, when thehandle 9 is in the horizontal position shown, thelower end 83 of thearm 81 will be pushed outwards by theprotrusion 84 on theouter spindle interlock 15 thereby causing theupper end 85 of thearm 81 to move inwardly and contact the trigger switch. This indicates that the door handle is in this position. Once the handle is depressed, theprotrusion 84 on theouter spindle interlock 15 will move away from thelower end 83 of thearm 81. The spring force of thetrigger switch 86 will push theupper end 85 of thearm 81 outwardly thereby indicating that thehandle 9 has been turned and that the door is not locked. This information can be used in the control of the door. For example, if the door handle has not been depressed in a predetermined period of time after the electromechanical locking mechanism has been activated using an electronic key, themotor 72 may be operated once more to lock the door once more. - Referring to
Figures 11 to 15 inclusive, there are shown views of the electromechanical locking mechanism with the outer escutcheon and most of the inner escutcheon removed. In these figures, the handleposition sensor activator 60 has been omitted for clarity. Thelatch 71 is pivotably mounted at oneend 87, about apivot pin 57 and at itsother end 88, a downwardly dependinghand 89 of thelatch 71 is located in anotch 91 formed in theouter spindle interlock 15. - In use, when an electronic key (not shown) is presented to the electronic key reader on the outer escutcheon, a control signal is sent through to the inner escutcheon and the motor is operated to turn the
wormscrew 73. As thewormscrew 73 turns, thewormscrew nut 74 will travel up along thewormscrew 73. As thewormscrew nut 74 travels upwards along the wormscrew, it will pull thehelical spring 76 upwards with it. As the helical spring moves upwards, thelatch 71 will move upwards also disengaging the downwardly dependinghand 89 from thenotch 91. The outer spindle interlock is therefore free to rotate once thehand 89 of thelatch 71 has been disengaged from thenotch 91. If the outer handle (not shown) is operated, the handles, the inner and outer spindles and the inner and outer spindle interlocks will rotate thereby causing theouter spindle 11 to operate a door lock (not shown) and allowing the door to be opened. - Once the handle has been returned to the horizontal position or after a predetermined period of time, the
motor 72 will be operated in the opposite orientation rotating thewormscrew 73 in the opposite sense. As thewormscrew 73 turns in the opposite direction, thewormscrew nut 74 will travel downwards on thewormscrew 73 thereby pushing thehelical spring 76 and in turn thelatch 71 downwards. If thelatch 71 and thenotch 91 have been realigned, thelatch 71 will be seated once more in thenotch 91, thereby preventing further rotation of the outer spindle interlock and the outer handle until a valid electronic key is presented once more to the electronic key reader. - An optical sensor (not shown), is provided and detects a
sensor tab 93 mounted on thewormscrew nut cover 75. The optical sensor and thesensor tab 93 work together to brake the system in both latch open and latch closed positions and also to stop thewormscrew nut 74 binding at the top of the wormscrew or running off at the bottom of the wormscrew. Thewormscrew nut cover 75 moves with thewormscrew 74. As thewormscrew nut cover 75 moves downwards on thewormscrew 72, the sensor tab will also be lowered on thewormscrew 73. Thesensor tab 93 is detected by the optical sensor. When thesensor tab 93 reaches a certain lowermost point on the wormscrew, the optical sensor will detect the absence of the sensor tab and themotor 72 may be stopped from further operation in that orientation to prevent disengagement of thewormscrew nut 74 from thewormscrew 73. Similarly, when the wormscrew is being operated in the opposite orientation and the sensor tab is moving upwards along the wormscrew, the optical sensor will, after a time, detect the absence of the sensor tab. This indicates that the sensor tab has moved above the optical sensor and the latch has been disengaged in which case and themotor 72 can be prevented from further operation in the present orientation to ensure that thewormscrew nut 74 does not bind at the top of the wormscrew. It will be understood that the motor is only temporarily prevented from operating in a particular orientation and can be reset once the optical sensor has detected thesensor tab 93 once more. - Referring specifically to
Figure 15 , there is shown a rear view of the locking mechanism shown inFigure 11 . It can be seen from the drawing, that thelower surface 95 of the latch, intermediate theend 87 and the downwardly dependinghand 89 is chamfered into a substantiallyU-shaped cam surface 95. Theinner spindle interlock 17 also comprises anotch 97 in which theU-shaped cam surface 95 sits. The sides of thenotch 97 are also chamfered into cam surfaces 99, 101 for complementary engagement of theU-shaped cam surface 95 of the latch, which will be described in more detail below. - As mentioned above, a feature of the
electromechanical locking mechanism 1 is that the locking mechanism must be able to be released from the inside without the use of an electronic key. Instead, it is necessary to allow simple operation of theinner handle 9 to cause the door to open. This is necessary in cases of emergency. It can be seen fromFigure 15 , that as theinner handle 9 is depressed, the inner spindle will begin to turn which will cause theinner spindle interlock 17 to rotate also. Theinner spindle interlock 17 and theouter spindle interlock 15 are allowed a limited amount of rotation relative to each other to allow theinner spindle interlock 17 to rotate in this manner. As theinner spindle interlock 17 rotates, depending on the direction of rotation of the handle, one of the cam surfaces 99, 101 will come into contact with thecam surface 95 on the underside of thelatch 71. Further rotation of thehandle 9 will cause thelatch 71 to be moved upwards as thecam surface 95 moves along thecam surface notch 97 and, importantly, the downwardly dependinghand 89 will be released from thenotch 91. As the downwardly dependinghand 89 is released from thenotch 91, theouter spindle interlock 15 and hence theouter spindle 11 will be free to rotate. - Further rotation of the
handle 9 will cause thearcuate protrusion 103 on theinner spindle interlock 17 to come into contact with one of theprotrusions outer spindle interlock 15 to rotate which in turn causes theouter spindle 11 to rotate and open a door lock (not shown). It can be seen from the foregoing construction of theprotrusions - In the embodiment shown, it is envisaged that with a 10 degree turn (clockwise or anti-clockwise) of the
inner handle 9, the cam (cam surfaces 99, 101) on either side of the notch on the inner spindle interlock engages with the knife-edge cam follower (cam surface 95) on the underside of the swinging pivot latch, causing disengagement of the latch from the notch in the outer spindle interlock, allowing the inner spindle interlock to engage the outer spindle interlock and continue turning both interlocks together to a further 45 degrees (allowing the spindle to turn in the lockset to open the door). Referring toFigures 16 to 19 , there are shown a plurality of views of the electromechanical locking mechanism similar toFigures 11 to 14 respectively but with theouter spindle interlock 15 removed. It can be seen fromFigures 16 to 19 , that the only portion of the latch that engages theinner spindle interlock 17 is thecam surface 95 on the underside of thelatch 71. - Referring to
Figures 20 to 22 , there are shown a plurality of views of the electromechanical locking mechanism similar toFigures 11 to 13 respectively but with the outer spindle, inner spindle interlock and inner handle removed. It can be seen fromFigures 20 to 22 that thecam surface 95 extends from theend 87 to the downwardly dependinghand 89 and that the only portion of the latch that engages theouter spindle interlock 17 is the downwardly dependinghand 89. - Referring to
Figure 23 , there is shown a side view of thelatch 71 resting on theinner spindle interlock 17. Furthermore, thewormscrew nut cover 75 has been removed to shown the engagement of thewormscrew nut 74 and thehelical spring 76. A helical channel is formed in the side of thewormscrew nut 74 to receive the helical spring. Referring toFigure 24 , there is shown a side view similar to the view shown inFigure 23 without thewormscrew nut 74. It can be seen that thewormscrew 73 extends downwardly inside the helical spring. - In the embodiments shown, it will be understood that there will be wiring extending rearwardly from the main PCB to the inner escutcheon side of the electromechanical locking mechanism to provide the control signals to operate the latch however these are standard and have not been shown for clarity. If preferred, wireless communications could be used instead however this would require at least a wireless transmitter in the outer escutcheon and a wireless receiver in the inner escutcheon.
- It will be further understood that the handles are not limiting and other types of handles could be used in their stead. Furthermore, a leaf spring, torsion spring or other spring could be used instead of the helical spring with appropriate modifications made to the engagement of the leaf spring, torsion spring or other spring and the wormscrew.
- There are several advantages to using a spring and a helical spring in particular as the connection between the wormscrew and the latch. The spring creates an 'elastic' connection between the pivot latch and the micro-motor/wormscrew assembly. It is envisaged that a non-elastic (i.e. rigid) connection would cause damage to a micro-motor very quickly in normal use. Secondly, the spring acts as a shock absorber when the external handle/escutcheon is subjected to attack from an intruder. The spring suppresses pivot latch bounce and protects delicate electronic components such as the light sensor and the micro-motor. In the down (i.e. locked) position, the spring is slightly compressed providing a down force on the pivot latch. This force would not be there without the spring. Thirdly, in the open position the pivot latch hits a physical stop before the light sensor (optical sensor and
sensor tab 93 arrangement) stops the motor. Therefore, after the pivot latch is stopped, the nut continues to travel a little more up the wormscrew until it reaches the stop position determined by the optical sensor. In that position, the spring will be slightly extended providing a small downward pulling force on the nut in preparation for closing after a fixed time. Fourth, the helical spring prevents the nut from rotating when the wormscrew rotates thus causing the nut to travel up and down the wormscrew. - In this specification the terms "comprise, comprises, comprised and comprising" and the terms "include, includes, included and including" are all deemed totally interchangeable and should be afforded the widest possible interpretation.
- The invention is in no way limited to the embodiments hereinbefore described and may be varied in both construction and detail within the scope of the claims.
