Definitions

  • the present application relates to a cylinder lock actuator for use in a lock housing.
  • the cylinder lock actuator provides an improved security Euro cylinder lock which is resistant to vandalism.
  • the cam is provided with a lug which will interact with the lock in the door, when the cylinder lock actuator is held therein, such that rotation of the cam leads to the lock being transferred from a locked to unlocked state, and vice versa.
  • the lock cylinder is mechanically connectable to the cam, such that rotation of the lock cylinder leads to rotation of the cam as desired.
  • the lock cylinder can be a traditional key-operated lock cylinder, comprising spring loaded pins which when the correct key is inserted therein will align and allow rotation of the lock cylinder and subsequent rotation of the cam. Similar lock cylinders are known and may comprise a thumb turn lock, wherein the thumb turn will also mechanically engage with the cam to lock and unlock the lock.
  • Most cylinder lock actuators comprise two lock cylinders either side of the central cam held there-between in a rotatable manner.
  • a first of the lock cylinders is to be positioned on the inside of the door in use, a second of the lock cylinders is positioned outside or on the exterior side of the door when in use.
  • the interior lock may be provided by the thumb turn disclosed above, or may be a key operated lock cylinder requiring the use of the correct key to allow rotation thereof.
  • the exterior lock cylinder will be a key operated lock cylinder to increase security, wherein this exterior lock cylinder is open to vandalism and attack by burglars trying to unlawfully gain entry to the lock and to unlock the door and gain entry to the building.
  • ES2401858 discloses a safety device for lock cylinders formed of inner and outer stators. Whereby, upon the removal of an outer stator the cam may be locked axially and radially. Further mechanisms are also presented which then lead to the cam being mechanically connected to the interior lock cylinder, such that the cam can only be rotated by means of the interior lock cylinder.
  • the interior side of the cylinder lock actuator, and in particular the mechanical components held within the cam can often be attacked by a burglar and may lead to a reduction in security and even actuation of the cam by the burglar.
  • Any mechanism to reduce the effectiveness of the burglar who has gained access to the interior of the cam in operating said cam leads to further time being spent by the burglar and a greater chance that the burglar is disturbed before gaining entrance to the building.
  • allowing the burglar access to the interior of the cam wherein elements have been left within the cam which make further access to the lock cylinder difficult, can again cause the burglar to spend more time and will thus improve the security of the lock in general.
  • the abovementioned aims are met by the cylinder lock actuator of the present invention.
  • the present invention relates to a cylinder lock actuator which has improved security features ensuring that the cam remains properly fixed to the interior lock cylinder after vandalism and removal of the exterior lock cylinder, whilst also ensuring that the burglar has limited access to parts of the cylinder lock actuator which are mechanically interconnecting the cam with the first lock cylinder.
  • the cylinder lock actuator further comprises elements which are held within the cam and which, upon vandalism of the lock and removal of the exterior lock actuator may remain and thereby provide obstructions to the burglar in attempting to gain further access to the inner elements of the cylinder lock actuator. In any event, any elements remaining in the cylinder lock actuator 1 can take no further part in operation of the cylinder lock actuator 1.
  • a cylinder lock actuator comprising a first lock cylinder, a second lock cylinder and a clutch mechanism, the clutch mechanism being adapted to selectively engage either the first lock cylinder or the second lock cylinder with a cam held rotatably in the cylinder lock actuator, wherein the cam is held in an axially moveable manner within the cylinder lock actuator, the cam being normally located in a first axial position within the cylinder lock actuator such that the clutch mechanism can engage either of the first lock cylinder or second lock cylinder therewith, the cylinder lock actuator further comprising biasing means which is adapted to axially move the cam into a second position upon removal of the second lock cylinder, the cylinder lock actuator comprising locking means which is adapted to constrain the cam with respect to the first lock cylinder when the cam is in the second position, and the biasing means and locking means are adapted to operate independently of the state of the clutch.
  • the present invention is directed to a mechanism of fixing rotation of the cam of the cylinder lock actuator after vandalism, thus ensuring that it cannot be rotated by a burglar from the exterior of the door but remains fully operable by a user on the inside.
  • the cylinder lock actuator of the invention also provides increased security by isolating the means of securing the cam post-vandalism from the normal functioning of the cam in the cylinder lock actuator prior to vandalism.
  • the cylinder lock actuator 1 is shown comprising a thumb turn 5 as the interior actuation mechanism and a key 6 as the exterior actuation mechanism. This is explicitly by way of example only. The skilled reader will fully understand that the interior side of the cylinder lock actuator 1 may also be operated by means of a key 6, and the use of the thumb turn 5 is purely exemplary. In the following, specific elements which are shown of the thumb turn 5 and the interior lock cylinder 2 as integrating with the thumb turn 5 are not disclosed. The drawings relate to the co-pending application: GB2001363.7 , which is held by the same Applicant.
  • Fig. 1 shows the general form of the cylinder lock actuator 1.
  • the cylinder lock actuator 1 comprises the first or interior lock cylinder 2, which is provided on the left hand side of Fig. 1 and is operated by the thumb turn 5.
  • the second or Fig. 1 shows the general form of the cylinder lock actuator 1.
  • the cylinder lock actuator 1 comprises the first or interior lock cylinder 2, which is provided on the left hand side of Fig. 1 and is operated by the thumb turn 5.
  • the housing 4 comprises a weakness 7, typically and as shown in the figures in the form of a slot through the housing 4 in the region of the most exterior end of the cam 10.
  • the weakness 7 is so located that upon vandalism of the cylinder lock actuator 2, the entire exterior lock cylinder 3 and the part of the housing 4 housing the exterior lock cylinder 3 will be snapped off and removed from the cylinder lock actuator 1.
  • the perspective view shown in Fig. 5 of the cylinder lock actuator 1 shows one possible state of the cylinder lock actuator 1 after it has been vandalised; the manner in which elements within the cam 10 are affected by vandalism is quasi-random, so it is not guaranteed what parts will remain within the cam 10.
  • the region of the housing 4 surrounding the lug gap 12 can further comprise a strengthening block which provides improved rigidity to this part of the housing 4. Such blocks are known in the art and no further description need be made in this disclosure.
  • the cylinder lock actuator 1 and the operation thereof can be seen in more detail.
  • the key 6 is shown inserted within the keyway of the exterior lock cylinder 3, such that the spring-loaded split pins are appropriately aligned and the exterior cylinder lock actuator 3 could be rotated by rotating the key 6.
  • This exterior lock cylinder 3 operates in a known manner and the operation of the spring-loaded split pins is well-known and is not further discussed herein.
  • the interior lock cylinder 2 comprising the thumb turn 5 as shown in Fig. 2 is a specific thumb turn 5 operating for the interior lock cylinder 2.
  • the cam 10 is generally cylindrical in nature and comprises an axial bore 17 along its entire length.
  • the axial bore 17 extends from the interior end of the cam 10 to the exterior end of the cam 10, as viewed when in the door, and comprises a clutch mechanism 13 therein.
  • the clutch mechanism 13 is configured so as to allow preferential control of rotation of the cam 10 by the interior lock cylinder 2 or the exterior lock cylinder 3.
  • the clutch mechanism 13 provides means for either of the interior lock cylinder 2 or the exterior lock cylinder 3 to take control over the cam 10, such that rotation of the relevant lock cylinder leads to rotation of the cam 10 to lock and unlock the lock.
  • the clutch mechanism 13 may further comprise a torsion ring 14 which is a generally circular, ring-like item positioned within the axial bore 17 of the cam 10.
  • the torsion ring 14 is so configured that it is within the cylinder lock actuator 1 prior to it being vandalised, in such a state that rotation of the torsion ring 14 will lead to rotation of the cam 10.
  • This first state of the torsion ring 14 is shown in Figs. 2 and 3 as being held within the axial bore 17 of the cam 10 by means of the exterior lock cylinder 3.
  • the torsion ring 14 may leave the first state and enter a second state. In the second state, the torsion ring 14 is no longer held at a particular axial position within the axial bore 17 by the exterior lock cylinder 3 and further rotation of the torsion ring 14 will not lead to rotation of the cam 10. In some embodiments, as shown in Fig. 6 for example, the torsion ring 14 will be completely free to be removed from the axial bore 17 of the cam 10. In other embodiments, for example as shown in Figs. 7 to 9 , the torsion ring 14 is held within the axial bore 17 of the cam 10. Figs.
  • FIG. 7 to 9 shows the torsion ring 14 held within the axial bore 17 by means of a swaged lip 18, such that the torsion ring 14 is able to move axially within the axial bore 17 of the cam 10, however it is now in a second state such that the torsion ring 14 is able to rotate but will not transmit torque from this rotation through to the cam 10. Allowing the torsion ring 14 to stay within the axial bore of the cam 10 provides a physical mechanism which thwarts a burglar's attempts to gain complete access to the interior of the cam 10.
  • the freely rotatable torsion ring 14 as shown in Fig.
  • the torsion ring 14 is provided with a torsion ring slot 14a in the interior circumferential surface of the torsion ring 14, the torsion ring slot 14a extending radially outward and having a form which matches the form of each of the drive bar lugs 15a, 16a.
  • the torsion ring slot 14a will thus accommodate the respective drive bar lug 15a, 16a of whichever drive bar 15, 16 is engaged with the torsion ring 14, such that rotation of the engaged drive bar 15, 16 will transmit the torque via the respective drive bar lug 15a, 16a to the torsion ring slot 14a.
  • the cylinder lock actuator 1 is configured such that the key 6 pushes the exterior drive bar 16 further within the axial bore 17 of the cam 10, thus ensuring that the exterior drive bar 16 is engaged with the torsion ring 14; this engagement meaning that the exterior drive bar lug 16a is located within the torsion ring slot 14a.
  • the exterior drive bar 16 is not able to rotate with respect to the exterior lock cylinder 3, and rotation of the exterior lock cylinder 3 leads to rotation of the exterior drive bar 16.
  • the interior drive bar 15 is held in an axially moveable and rotationally fixed manner within the interior lock cylinder 2. This configuration means that the interior drive bar 15 may move axially within the interior lock cylinder 2 and axial bore 17 of the cam, but cannot rotate with respect to the interior lock cylinder 2. Rotation of the interior lock cylinder 2 leads to rotation of the interior drive bar 15 - which will be transmitted to the cam 10 when the interior drive bar 15 is engaged with the torsion ring 14.
  • the mechanism described above by which the exterior drive bar 16 is pushed into alignment with the torsion ring 14 can be used with the interior lock cylinder 2. If the interior lock cylinder 2 is so structured that the thumb turn 5 or interior key operated lock cylinder were to provide a pushing force to axially move the interior drive bar 15 into engagement with the torsion ring 14, the interior drive bar 15, by means of the interior drive bar lug 15a engaging with the torsion ring slot 14a, would control rotation of the torsion ring 14.
  • the clutch mechanism 13 as described above could be appropriately used with any cylinder lock actuator 1.
  • the particular feature of the torsion ring 14 being held within the axial bore 17 is, therefore, not limited to the use with the further aspects of the cylinder lock actuator 1 described herein.
  • the clutch mechanism 13, and in particular the torsion ring 14, of the present disclosure may therefore be used with any cylinder lock actuator 1 and provides the further benefit, when the torsion ring 14 remains within the axial bore 17 of the cam 10, of providing a physical item which serves no purpose in turning the cam but which provides both a distraction and physical impediment to a burglar's further attack after removing the exterior lock actuator 3.
  • the torsion ring 14 is, therefore, a separate invention in its own right and can be used in other known cylinder lock actuators 1.
  • the torsion ring 14 has a first state in which the rotation of the torsion ring 14 is transmitted to rotate the cam 10.
  • a second state of the torsion ring 14 exists in which the rotation of the torsion ring 14 within the axial bore 17 of the cam 10 will not lead to any torque being transmitted to the cam 10, such that the torsion ring 14 can rotate freely.
  • either the torsion ring 14 will be easily removable from the axial bore 17 of the cam 10, or the torsion ring 14 can be held within the actual bore 17 of the cam 10 by means of the swaged lip 18.
  • the torsion ring 14 can be provided with an extension which interacts with an element within the axial bore 17 of the cam 10, such that the relative rotation between the torque ring 14 and cam 10 is not possible.
  • the extension on the torsion ring 14 can take a number of different forms, the Figures showing one particular option thereof.
  • a removable element can be located therein such that the removable element extends beyond the outer circumference of the torsion ring 14 to create the appropriate extension.
  • Fig. 7 shows the extension being in the form of a bearing ball 24, however this is by way of example only.
  • a bearing ball 24 is easy to manufacture or obtain from suppliers, and can readily be integrated into the cylinder lock actuator 1.
  • the bearing ball 24 may be replaced by a cube, heptagon, decagon or any other appropriate shape such that parts of the extension will extend out of the pocket 25 and beyond the outer circumference of the torsion ring 14.
  • a slot 23 may be provided on the interior of the axial bore 17, as shown in Fig. 4 , slot 23 allowing for the torsion ring 14 to slide into the axial bore 17 with bearing ball 24, or equivalent, held within the pocket 25. With the ball nearing 24 within the slot 23, it will be appreciated that the bearing ball 24 will transmit any torque applied to the torsion ring 14 via the side of the pocket 25 to the slot 23 on the interior of the axial bore 17 of the cam 10.
  • the end of the axial bore 17 in the cam 10 which is on the exterior side of the cylinder lock actuator 1, is provided with a region of a first diameter.
  • This first diameter section 26, seen in Fig. 4 has a diameter which allows the torsion ring 14 to enter into the axial bore 17 of the cam 10 and without presence of the bearing ball 24, will allow for the torsion ring 14 to freely rotate without transmitting torque to the cam 10. If, however, the bearing ball 24 is present and within the pocket 25 of the torsion ring 14, when this assembly is positioned within the first diameter section 26 of the axial bore 17, rotation of the torsion ring 14 will transfer the torque through the bearing ball 24 to the slot 23 of the axial bore 17 as described above.
  • the first diameter section 26 extends a distance within the axial bore 17 to a step 27 which signals the start of a second diameter section 28 of the axial bore 17. It is preferred that a straight sided step 27 is provided, as this is straightforward to manufacture and provides a definite stop to the torsion ring 14 entering further into the axial bore 17 of the cam 10.
  • the interior diameter of the second diameter section 28 is smaller than the outer diameter of the torsion ring 14, thus meaning that the torsion ring 14 can only extend into the axial bore 17 in the region of the first diameter section 26.
  • the torsion ring 14 When the bearing ball 24 is in the pocket 25 of the torsion ring 14, the torsion ring 14 can be positioned within the first diameter section 26 such that the bearing ball 24 is within the slot 23 and the bearing ball 24 also rests against the step 27.
  • the bearing ball 24 is removable from the pocket 25, thus meaning that the step 27 holds the bearing ball 24 within the pocket 25.
  • the presence of the exterior lock cylinder 3 ensures that the torsion ring 14 is pushed up to the full extent of the first diameter section 26, such that the bearing ball 24 is held within the pocket 25.
  • the innermost end of the exterior lock cylinder 3 is so sized that it will fit within the first diameter section 26: that is, the external diameter of at least the end of the exterior lock cylinder 3 is smaller than the inner diameter of the first diameter section 26.
  • the second diameter section 28 has an interior diameter which is smaller than the exterior diameter of the exterior lock cylinder 3. The presence of the exterior lock cylinder 3 ensures that the torsion ring 14 remains in the first state, that is the torsion ring 14 remains fully abutting the step 27 such that the bearing ball 24 remains within the pocket 25.
  • the second state is defined as any state in which rotation of the torsion ring 14 does not lead to rotation of the cam 10.
  • the removal of the exterior lock cylinder 3 means that there is no longer any element physically holding the torsion ring 14 within the cam 10: this further means that the torsion ring 14 is free to be removed and may simply fall out, or be pushed out by other elements within the cam 10, after removal of the exterior lock cylinder 3.
  • a further possibility for defining the torsion ring 14 is that the extension in the outer circumferential surface of the torsion ring 14 or in the rear face of the torsion ring 14 in the second example given above, is not removable.
  • removal of the exterior lock cylinder 3 after vandalism allows the torsion ring to move axially along the axial bore 17 and to fall out of the axial bore 17 as shown in Fig. 6 , thus taking the permanent extension with it and out of the slot 23 in the axial bore 17.
  • the interior lock cylinder 2 can most clearly be seen in Figs. 4 and 9 and relate to fixing the cam 10 to the interior lock cylinder 2.
  • the end of the interior lock cylinder 2 which is held within the axial bore 17 of the cam 10 has a diameter which is smaller than the interior diameter of the second diameter section 28.
  • the end of the interior lock cylinder 2 also comprises a blind hole 22 or indent, into which the interior drive bar 15 can slidably engage.
  • the interior drive bar 15 is able to axially move within the blind hole 22 of the interior lock cylinder 2, however the interior drive bar 15 is not able to rotate with respect to the interior lock cylinder 2 and is held within the blind hole 22 in a manner that does not permit relative rotation.
  • the interior drive bar 15 can move in and out of complete engagement with the blind hole 22, but cannot rotate with respect thereto. By configuring the interior drive bar 15 so that it cannot rotate with respect to the interior lock cylinder 2, ensures that rotation of the interior lock cylinder 2 leads to rotation of the interior drive bar 15. When the interior drive bar 15 is engaged with the torsion ring 14, rotation of the interior lock cylinder 2 thus leads to rotation of the cam 10.
  • the interior drive bar 15 preferably comprises two interacting elements.
  • the first part of the interior drive bar 15 comprises a generally cylindrically extending form which comprises the drive bar lug 15a.
  • the second part of the interior drive bar 15 comprises a drive bar fixed part 20 and a drive bar spring 19.
  • the drive bar spring 19 can be seen in Figs. 3 and 4 , this being located between the drive bar fixed part 20 and the cylindrical part of the drive bar 15.
  • the drive bar spring 19 is generally affixed to the drive bar fixed part 20, and provides a repulsive force between the drive bar fixed part 20 and the cylindrical part of the interior drive bar 15.
  • the effect of the essentially spring loaded interior drive bar 15, can best be seen in Fig. 3 . As can be seen in Fig.
  • the lock prior to vandalism is one in which the interior drive bar 15 is spring-loaded into engagement with the torsion ring 14.
  • the present cylinder lock actuator 1 is one in which the interior lock cylinder 2 is generally biased to control the rotation of the torsion ring 14. Only when the key 6 is inserted into the exterior lock cylinder 3, as shown in Fig. 2 , will the exterior drive bar 16 push against the drive bar spring 19 to disengage the interior drive bar 15 from the torsion ring 14. Removal of the key 6 means that the drive bar spring 19 pushes the cylindrical part of the interior drive bar 15 against the exterior drive bar 16, pushing the exterior drive bar 16 out of engagement with the torsion ring 14 and ensuring that the interior drive bar 15 is in engagement with the torsion bar 14.
  • the natural state of the cylinder lock actuator 1 without the presence of the key 6 fully inserted is one in which the interior lock cylinder 2 is always engaged to control the rotation of the cam 10.
  • the blind hole 22 is structured to fully hold the interior drive bar fixed part 20 at the end of the blind hole 22, allowing the drive bar spring 19 to extend and push the cylindrical part of the interior drive bar 15 into engagement with the torsion ring 14.
  • no part of the thumb turn 5 is needed to push the interior drive bar into engagement with the torsion ring 14, as it is only the presence of the key 6 in the exterior lock cylinder 3 which removes rotational control of the cam 10 from the interior lock cylinder 2.
  • ejection spring 21 within the blind hole 22, in order to promote that all elements of the clutch mechanism 13 are expelled or ejected from the axial bore 17 of the cam 10 when the lock is vandalised.
  • the ejection spring 21 as shown in Fig. 4 has the structure of a cone spring, wherein this cone spring would be fully compressed between the interior drive bar fixed part 20 and the end of the blind hole 22 when the cylinder lock actuator 1 is assembled and prior to vandalising.
  • the ejection spring 22 will provide a further force on the interior drive bar fixed part 20, pushing this further outward and further ensuring engagement of the interior drive bar 15 with the torsion ring 14.
  • the exterior drive bar 16 Upon removal of the exterior lock cylinder 3 by vandalism, the exterior drive bar 16 will fall out of the axial bore of the cam 10, and the torsion ring 14 will leave the first state and will either be ejected or left in a rotationally free manner within the first diameter section 26 of the axial bore 17 - i.e. it would enter the second state.
  • the interior drive bar 15 will then be forced out of the axial bore 17 by the force of the ejection spring 21, thus facilitating the expulsion of both drive bars 15, 16 from the axial bore 17. If the axial bore 17 does not have the swaged lip 18, it is clear the ejection spring 21 would also provide a force on the torsion ring 14 to expel this from the axial bore 17.
  • the ejection spring 21 would make drilling extremely inconvenient or even impossible. This would again delay the burglar and could dissuade the burglar from continuing to attack the lock actuator 1, and would certainly give greater opportunity for the burglar to be seen during the attempt to enter the building.
  • the interior drive bar fixed part 20 Rather than having a separate ejection spring 21 acting on the interior drive bar fixed part 20, another embodiment is for the interior drive bar fixed part 20 to comprise a spring itself acting against the end of the blind hole 22. Such a design would prove a spring force that both leads to the interior drive bar 15 being usually engaged with the torsion ring 14 and also being strong enough to eject the interior drive bar 15, torsion ring 14 and exterior drive bar 16 if the lock is vandalised. Such a design for the interior drive bar 15 is not shown in the figures. This integrated ejection interior drive bar 15 would not leave the spring within the blind hole 22 of the interior lock cylinder 2, but would assist in ensuring the removal of the clutch mechanism 13 with or without leaving the torsion ring 14 in the axial bore 17.
  • the interior drive bar 15 with the cylindrical drive bar element and a drive bar spring 19 alone.
  • the drive bar spring 19 would act against the end of the blind hole 22 to push the cylindrical part of the interior drive bar 15 into engagement with the torsion ring 14, and upon the lock being vandalised would also assist in ejecting the clutch mechanism 13 out of the axial bore 17 of the cam 10.
  • FIG. 1 prior to the cylinder lock actuator 1 being vandalised, the cam 10 can be controlled via the clutch mechanism 13. The cam 10 rotates independently of each of the interior lock cylinder 2 and exterior lock cylinder 3, when the respective lock cylinder 2, 3 is not engaged with the clutch mechanism 13. After the lock has been vandalised and the exterior lock cylinder 3 is removed, as shown in Fig. 5 , the cylinder lock actuator 1 enters a vandalised condition where the cam 10 is permanently engaged with the interior lock cylinder 2. In this vandalised state, the cam 10 is locked to the interior lock cylinder 2 and the cam 16 cannot rotate with respect to the interior lock cylinder 2.
  • the movement of the cam 10 is irrespective of any aspect of the clutch mechanism 3, is achieved by entirely independent means and nothing held within the clutch mechanism triggers or influences the locking of the cam 10 to the interior lock cylinder 2.
  • the cam 2 has a locking slot 31 therein. Whilst the locking slot 31 is shown extending through the wall of the cam 10, this is by way of example only. The locking slot 31 may, in fact, be an indent on the interior side of the axial bore 17 of the cam 10, providing a blind hole or indent which does not pass through the side wall of the cam 10. The number of locking slots 31 is not limited, and it is contemplated that two locking slots 31 will be present within the cam 10, generally one on either side of the cylinder lock actuator 1.
  • the means of fixing the cam 10 to the interior locking cylinder 2 is by means of one or more locking pins 30.
  • the locking pins 30 are held within the interior lock cylinder 2 and are preferably biased out of the interior locking cylinder 2.
  • the interior lock cylinder 2 comprises a locking pin hole or bore 34 in a position behind the blind hole 22. This position is at a location more interior and away from the cam 10 than the blind hole 22, and crucially the locking pin hole 34 is an entirely separate hole or slot in the interior lock cylinder 2 from the blind hole 22. This means that the locking pin hole 34 and locking means for holding the cam 10 in rotational alignment with the interior lock cylinder 2, are completely separate from the blind hole 22 and any elements of the clutch mechanism 13.
  • the locking pin hole 34 can either be a single blind hole in which a single locking pin 30 is located, or as shown in Fig. 4 , the locking pin hole 34 can be a through hole passing through from one side of the interior lock cylinder 2 to the other side thereof. In this scenario, two locking pins 30 are located within the locking pin hole 34 and a single locking pin spring 33 is positioned there-between to bias the locking pins 30 out of the locking pin hole 34. In the scenario where a single blind hole is present for the locking pin hole 34, the locking pin spring 33 would be positioned between the end of the locking pin blind hole and the locking pin 30 to bias the locking pin 30 out of the locking pin blind hole.
  • Fig. 1 prior to the cylinder lock actuator 1 being vandalised, the cam 10 is so positioned that the locking slot 31 blocks the locking pin 30 from exiting the locking pin hole 34. In this arrangement, the end of the locking pin 30 is pushed against the interior surface of the axial bore 17, but does not stop rotation of the cam 10 and normal operation of the locking pin actuator 1.
  • the cam 10 is located in an orientation such that the locking slot 31 now aligns with the position of the locking pin 30, and the locking pin 30 is biased into the locking slot 31. The same would occur if the locking slot does not extend through the surface of the cam 10, but rather forms an indent on the interior surface thereof.
  • the cam 10 is then mechanically connected with the interior lock cylinder 1 and cannot rotate freely without rotation of the interior locking cylinder 2.
  • the interior lock cylinder 2 can only be rotated by rotating the thumb turn 5 or, if the thumb turn 5 is replaced by a key cylinder, by introducing a key into the interior lock cylinder 2, properly aligning the key and allowing rotation of the interior lock cylinder 2 which will also rotate the affixed cam 10.
  • the cam 10 is locked in rotational alignment with the interior lock cylinder 2 and cannot be rotated by the burglar after vandalising the lock from the exterior side of the door. That is, because the interior lock cylinder can only be rotated by someone on the interior side of the door and because the cam 10 is rotatably fixed with respect to the interior lock cylinder 2 after lock vandalism, the burglar on the exterior of the door cannot rotate the cam 10 because the interior lock cylinder 2 blocks rotation thereof.
  • the locking slot 31 is shown as an extended slot in the figures, however the locking slot 31 could be simply a round hole which accommodates the size of the locking pin 30 to allow the locking pin 30 to extend into the locking slot 31, even when circular, thus ensuring the cam 10 and the interior lock cylinder 2 cannot freely rotate independently upon lock vandalism.
  • the use of the locking slot 31 allows for the locking pin 30 to engage with the locking slot 31 at a greater number of relative angles between the locking pin 30 and locking slot 31, thus improving the locking together of these two elements - the limited relative rotation which the locking slot 31 then affords is not, however, enough for the burglar to operate the cam 10.
  • the exterior surface of the interior lock cylinder 2 has a first end with a first diameter which will fit within the second diameter section 28 of the axial bore 17, which extends far enough along the interior lock cylinder 2 to allow this to fully extend into the axial bore 17 and position the interior drive bar 15 for alignment with the torsion ring 14.
  • the interior lock cylinder also has a second region with a larger diameter and this forms a discontinuity and this is shown as spring step 36 in Fig. 6 .
  • the spring step 36 is the surface against which the cam spring 34 acts to push the cam 10 away from the interior lock cylinder 2.
  • the lug springs 41 can be so designed as to bias the lug 11 into a location which will align with the lug gap 12 when the cylinder lock actuator 1 has not been vandalised. Movement of the lug 11 does not require a great amount of force, thus meaning that the lug springs 41, if present, need only be strong enough to effect alignment of the lug 11 within the lug gap 12. To this end, the force applied by the lug springs 41 onto the lug 11 is such that it will provide very little, if any, counter force to the movement of the cam 10 upon vandalism of the cylinder lock actuator 1 when the cam 11 strikes the side of the lug gap 12.
  • the exterior lock cylinder 3 Upon vandalising the cylinder lock actuator 1, the exterior lock cylinder 3 is removed and the remaining parts may take the form as shown in Fig. 5 ; as will be appreciated from the above, it is possible for the interior drive bar 15 and/or the torsion ring 14 to remain within the cam 10 in a non-functional state. Once the exterior lock cylinder 3 has been removed this no longer holds the cam 10 in position against the cam spring 35 and the cam spring 35 pushes the cam 10 away from the interior lock cylinder 2, until the one or more locking slots 31 engages with the one or more respectively aligned locking pins 30.
  • the locking pins 30 are then biased into the locking slot 31, whether this is the through slot as shown in the figures or an indent on the interior of the axial bore 17, the cam 10 is then held in a fixed manner with regard to the interior lock cylinder 2. Rotation of the cam 10 is then only possible by actuating the interior lock cylinder 2, either by means of the thumb turn 5 shown or the key if a key operated interior lock cylinder 2 is present. This means that the burglar is unable to rotate the cam 10, as it is locked properly to the interior lock cylinder 2, but a person on the interior side of the cylinder lock actuator 1 is able to lock and unlock the lock as normal.
  • the swaged lip 18 at the end of the axial bore 17 will stop the torsion ring 14 from exiting the axial bore 17.
  • the burglar will hopefully invest further time in trying to remove the torsion ring 14, either in the mistaken belief that this will aid in the attack or because it is in the way.
  • the torsion ring 14 is able to move axially within the first diameter region 26 and will leave the first state such that the bearing ball 24, or other item, is no longer held in the pocket 25 by the step 27.
  • Fig. 9 shows the state of the fully vandalised cylinder lock actuator 1.
  • the exterior lock cylinder 3 has been removed, the external drive bar 16 has also been removed, the interior drive bar 15 has been ejected from the blind hole 22 and the cam spring 35 has extended and pushed the cam 10 into locked alignment by means of the locking pins 30.
  • the torsion ring has generally been pushed forward to engage with the swaged lip 18, and in so doing the bearing ball 24 has fallen out and can no longer transmit torque through to the cam 10 and the torsion ring 14 is able to rotate freely and move axially between the swaged lip 18 and the step 27.
