Definitions

  • the present invention relates to an improvement in the design of locks and keys. More particularly, the present invention relates to improvements in cylinder locks.
  • a conventional key-operated pin-tumbler lock mechanism is commonly used in cylinder locks.
  • This type of lock mechanism comprises a casing with a cylindrical hole which houses a plug.
  • the plug has an axial slot for receiving a key, known as the keyway, and a series of transverse holes which are aligned with a series of corresponding holes in the lock casing.
  • the holes contain a set of key pins of differing lengths, behind which are a set of spring-loaded driver pins. Without a key in the lock, the pins are biased by the springs such that the key pins are located in the plug while the driver pins sit across the interface (the shear line) between the plug and the casing, thereby preventing rotation of the plug.
  • EP0892130 B1 describes a lock cylinder mechanism in which a series of passages extend across the diameter of the plug, intersecting the keyway.
  • Each passage contains a pair of pins which are biased towards each other by compression springs.
  • the pins may be of the same length or one of the pins may be longer than the other pin. Where one pin is longer than the other, the shorter pin is associated with a stronger spring, such that when the lock is in its rest position, the longer pin projects across the shear line.
  • the shorter (or one of the same length) pins are moved slightly outwardly, allowing the longer (or other of the same length) pins to move inwardly into a set of recesses provided in the key so that they are within the confines of the plug and no longer project across the shear line, allowing the plug to rotate.
  • the key may have two rows of recesses for engagement with a single set of pins.
  • the shank of the key has a C 2 -axis of rotational symmetry so that the key can operate the lock in either orientation of the shank in the keyway.
  • the mechanism described in this patent is more resistant to picking, since the usual method of applying a torque to the plug to locate the shear line would prevent the locking pins moving to the unlocked position, thereby preventing this method of manipulation.
  • the locking assembly comprises a key as defined in claim 1 and a key-operable lock comprising:
  • Two retaining means may be provided, one at each end of the keyway.
  • the locking member may extend out of the plug and/or casing in the locked position of the lock.
  • embodiments of the present invention provide a lock, operable by a key, and which includes a locking member extending out of the plug and/or casing.
  • a lock operable by a key
  • which includes a locking member extending out of the plug and/or casing This is contrary to known locks where the entire locking mechanism is housed within the plug and/or casing.
  • conventional thought might lead one to believe that having the locking member extending out of the lock would make the lock less secure than if it were fully enclosed within the lock, since this feature would make it easier to access and therefore potentially easier to tamper with than a mechanism that is fully enclosed, the Applicants believe that the present aspect has certain advantages.
  • having the locking member extending out of the plug and/or casing allows for the locking member to be much more easily inserted, removed or replaced since the reminder of the lock may remain in situ and/or substantially unaltered during these operations.
  • a different locking member e.g. configured for use with a different key.
  • the present invention may also enable the locking member to be inserted into the lock as the last step in the assembly of the lock.
  • a specified amount e.g. 30°, 90°, 180°
  • having the locking member extending out of the lock may provide a visual indication that the lock is in the locked position and/or that the lock comprises more than simply a standard pin tumbler type mechanism, which may help to deter persons looking to pick or tamper with the lock.
  • the locking member may be axially movable by a complementary key such that when said key is inserted into the keyway, the locking member causes the locking means to relocate to thereby place the lock in the unlocked position.
  • the key comprises a handle and a shaft having a stop shoulder and an unlocking shoulder, the stop shoulder and the unlocking shoulder being axially spaced apart by a predetermined distance such that when the shaft is inserted into the keyway of the lock, the unlocking shoulder serves to move the lock into an unlocked position when the stop shoulder abuts the lock to denote that the shaft is fully inserted in the keyway.
  • the unlocking shoulder is provided by a first partial transverse cut-out in the stop shoulder.
  • a second partial transverse cut-out extends along the length of the shaft to allow the shaft to by-pass a partial obstruction in the keyway, and wherein the width of the shaft narrows to produce a gap, the gap being provided to permit the key to turn past the obstruction to unlock the lock.
  • the locking member may also extend out of the plug and/or casing in the unlocked position of the lock.
  • the locking member may be configured to move from a first (locked) position projecting a first distance from the plug and/or casing to a second (unlocked) position projecting a second distance from the plug and/or casing.
  • the first distance may be greater than the second distance such that the locking member is moved inwardly from the locked position to the unlocked position.
  • the locking member may directly or indirectly cause the locking means to relocate.
  • movement of the locking member directly moves the locking means into an unlocked position.
  • movement of the locking member may allow the locking means to relocate into an unlocked position.
  • Embodiments of the locking mechanism are foreseen such that it is only operable by a key correctly configured to move the locking member to cause the locking means to move to an unlocked position.
  • the lock mechanism can be used alone or in conjunction with an additional (primary) locking mechanism such as a conventional pin-tumbler lock mechanism, and thus can be used to provide an additional level of security to conventional lock systems.
  • the locking member may be capable of causing the locking means to move into a further locked position, for example when a non-complementary key is inserted into the lock.
  • a key configured to operate a particular lock is capable of moving the locking member by the exact distance required to cause the locking means to move into the unlocked position. Therefore without the correct key, it is difficult to guess the unlocked position of the locking means so that the lock is more resistant to picking.
  • the locking means may relocate into one of a first or a second unlocked position.
  • the provision of first and second unlocked positions provides a master key facility.
  • the locking means may move into the first unlocked position upon insertion of a complementary standard key into the lock, and into the second unlocked position upon insertion of a complementary master key into the lock.
  • the locking member may be axially moveable within the plug, within the casing or within the plug and casing.
  • the locking member is wholly or partially received in the plug when the lock is in an unlocked position.
  • the locking member is wholly or partially received in the casing when the lock is in an unlocked position.
  • Part of the locking member may extend out of the plug and/or casing in some or all positions of the lock.
  • the locking member may extend out of the plug and/or casing only when the lock is in a locked position with no key inserted.
  • the whole of the locking member is confined within the plug and/or casing in all unlocked positions of the lock, such that no part of the locking member protrudes from the plug and/or casing in these positions.
  • the locking member may have a front end, a rear end and a surface therebetween. In an embodiment, the rear end of the locking member is situated within the plug while the front end of the locking member extends out of the plug in all positions of the lock.
  • the locking means may form a part of or be integral to the casing or the plug.
  • the locking means may form a part of or be integral to the locking member.
  • the locking means may take the form of a projection (or clip) which extends from the locking member, the plug or the casing.

  • the first and second recesses are provided in the surface of the locking member. The first and second recesses may be axially aligned and spaced apart from each other by a predetermined distance.
  • the locking member is constituted by a rod.
  • the rod may be substantially cylindrical or cuboidal.
  • the recess or recesses may be provided in the surface of the rod, which receive the locking means in an unlocked position of the lock.
  • a part of the rod constitutes the locking means.
  • the rod may contain a further part which aligns with a recess in the plug or casing in the unlocked position.
  • the further part of the rod may constitute a portion of reduced diameter.
  • the lock additionally comprises a biasing means.
  • the biasing means may be disposed so that it abuts the rear end of the locking member.
  • the biasing means comprises a spring.
  • the biasing means may be provided by a resilient member which deforms when the locking member is moved against its bias.
  • the biasing means may provide a biasing force which returns the locking member to its rest position once a key has been removed from the lock, and in so doing the locking member causes the locking means to return to the locked position (i.e. with the locking means projecting across the interface between the plug and the casing).
  • the retaining means may retain at least a part of the locking member within the plug and/or casing, or it may retain the whole of the locking member within the plug and/or casing in all unlocked positions of the lock.
  • the retaining means may therefore serve to retain at least a part of the locking member in the plug and/or casing at all times, and prevents the locking member from being completely detached from the plug and/or casing when in the locked position.

  • the locking member may be constituted by a rod which comprises a first diameter portion forming the locking means and a second diameter portion, having a smaller diameter than the first diameter portion, arranged to align with the retaining means so as to allow the key to turn past the retaining means when the lock is in its unlocked position.
  • an aperture is provided which engages the locking means when the lock is in a locked position, allowing the locking means to span the interface between the plug and the casing so that rotation of the plug is prevented.
  • the aperture may be provided in the locking member, or it may be provided in the plug or casing. In a particular embodiment, the aperture is provided in an inner surface of the casing.
  • the lock may further comprise an additional (primary) locking mechanism.
  • the additional locking mechanism may be arranged such that radial movement of a component is required to place the lock in an unlocked position.

  • the primary locking mechanism is a locking mechanism of the type described in the Applicant's earlier European patent EP0892130 B1 .
  • an additional set of holes may be provided in the plug and/or casing to accommodate the pins and thereby permit removal of the key at a second position of the lock.
  • This second position may be such that removal and/or replacement of the locking member is permitted (e.g. by bringing the locking member clear of its retaining means).
  • the lock may be changed by simply changing the locking member (e.g. such that it extends out of the lock by a different amount either when in the locked position or in the unlocked position) and replacing the key with one having the same shaft configuration as before (i.e. to align the pins of the additional locking mechanism) but having an unlocking shoulder set back a different distance from the stop shoulder in order to accurately move the new locking member into the unlocked position.

  • the unlocking shoulders will not extend uninterrupted across the thickness of the key but will be bounded on at least one side by material extending forwardly of the unlocking shoulder to form one of the stop shoulders.
  • the unlocking shoulders will effectively be provided within a portion of each stop shoulder and, as such, it is believed that this will make the key significantly more difficult to copy since it will not be possible to simply file back a stop shoulder across its entire width in order to provide one of the unlocking shoulders. Instead, it will be necessary to file back or cut-out only a portion of each stop shoulder to the appropriate distance and this will be much more difficult to accurately achieve.
  • the unlocking shoulders may be closer to the handle than the stop shoulders so that the unlocking shoulders can mate with a locking member projecting from the lock when the key is inserted in a keyway.

The cut-out may be provided such that the portion of the locking member extending out of the lock in the locked position is arranged to abut an unlocking shoulder of the key such that further insertion of the key into the lock can move the locking member to an unlocked position when the stop shoulders abut an end of the plug and/or casing.
  • the cut-out in the locking member may also provide a surface to abut a retaining means to hold the locking member in the lock. For example, the surface may abut an inner face of a projection or clip provided on the plug and/or casing to prevent the locking member from being extracted from the lock in the locked position.
  • only a portion of an end surface protruding from the lock may be configured to mate with the unlocking shoulders.
  • the first transverse cut-outs may be provided at one side of each stop shoulder or at the other side of each stop shoulder. Thus, one side/edge of the stop shoulders may be cut away to form the cut-outs.

  • This feature may be employed where the lock is configured for the key to be insertable and retractable in one orientation (e.g. at 0°) and in the opposite orientation (e.g. after the key has been rotated through 180°).
  • the lock may be provided with a second retention means (e.g. projection or clip provided on the casing) arranged to retain the locking member after it has been rotated by 180°.
  • profile of the key may be asymmetrical by providing a partial transverse cut-out at only one side of each stop shoulder.

  • each unlocking shoulder (or end surface of the cut-out) may be constituted by a curved surface for mating with a similarly curved nose provided on a free end of the locking member. This allows the unlocking shoulder to be formed by a simple counter-boring operation as opposed to traversing a cutter blade. The forming of such unlocking shoulders can therefore be carried out more quickly and more accurately while also providing a greater contact area between the unlocking shoulder and the locking member.
  • a side surface and/or a bottom surface of each transverse cut-out may be curved or planar.

  • One or more of the keys may then be further processed so that they have a different unlocking shoulder depth, corresponding to a different lock.
  • the invention also provides an advantage in the manufacture of keys and locks. For each combination of the pins inside the lock, there is usually only one key. In the case of the present invention, for each combination of pins, a number of different locks can be produced by varying the distance the locking member must move in order to place the locking means in its unlocked position. Complementary keys to the different locks can easily be manufactured by altering the spacing between the stop shoulders and the unlocking shoulders. Thus the present invention facilitates the manufacture of a greater number of keys and locks, with increased security and much improved mater keying.

A locking means in the form of a ball 44 is seated in the cut-out 34. In the locked position of the lock 10, as shown in Fig. 1 , the locking rod 24 is biased outwards. The ball 44 extends through the opening 20 in the plug 12 to engage with the aperture 22 in the casing 14, such that the ball 44 spans the interface between the plug 12 and the casing 14 which prevents the plug 12 from rotating within the casing 14.

  • the unlocking shoulder 86 of the key 70 abuts the front end 26 of the locking rod 24.
  • the unlocking shoulder 86 is cut to a specified depth (d) so that when the key 70 is inserted into the lock 10, the unlocking shoulder 86 moves the locking rod 24 into the plug 12 by a predetermined distance. This aligns the recess 42 in the cut-out 34 of the locking rod 24 with the aperture 22 in the casing 14, so that the ball 44 is received in the recess 42. In this position of the lock, as shown in Figs.
  • the ball 44 is completely received within the confines of the plug 12 so that the plug 12 is allowed to rotate within the casing 14 (provided, of course, that each of the transverse pins 52, 54 are also moved into the confines of the plug 12 by alignment of the recesses 82 in the key shank 74). From Figure 4 it can also be seen that in the unlocked position, an upper portion of the ball 44 projects into the opening 20 within the plug 12. This prevents axial movement of the ball 44 relative to the plug 12 so that the locking rod 24 cannot be removed from the plug 12 when the ball 44 is in the unlocked position.
  • Figures 6a to 6d illustrate that the depth of the unlocking shoulder on the key must be complementary to the configuration of the locking rod, otherwise rotation of the plug (and therefore unlocking of the lock) is prevented.
  • Fig. 6a shows a lock A in combination with a complementary key A, not in accordance with the present invention.
  • the key A has an unlocking shoulder 86 of depth x (with respect to a first stop shoulder) which moves the locking rod 24 into the plug 12 by a distance which aligns the recess 42 in the locking rod 24 with the aperture 22 in the casing 14.
  • the ball 44 is received in the recess 42 and no longer blocks rotation of the plug 12 so that the lock A may be unlocked.
  • Fig. 6b shows a different lock B in combination with a complementary key B, not in accordance with the present invention.
  • the key B has an unlocking shoulder 86 of depth y (with respect to a first stop shoulder) which moves the locking rod 24 into the plug 12 by a different distance to align the recess 42 with the aperture 22.
  • key B is inserted into lock A.
  • the depth y of key B is too great for the unlocking shoulder 86 to make contact with the front end 26 of the locking rod 24, so that the key B cannot move the locking rod 24 into the plug 12 to align the ball 44 with the recess 42.
  • the ball 44 is therefore retained across the interface between the plug 12 and the casing 14, preventing rotation of the plug 12.
  • key A is inserted into lock B. Because the depth x of key A is too small, the unlocking shoulder 86 moves the locking rod 24 too far into the plug 12 to align the ball 44 with the recess 42. Lock B can therefore not be unlocked by key A.
  • the shapes of the cut-out and the recess in the locking rod may take a number of different forms.
  • the cut-out and recess are replaced by an angular depression 90 with sloped sides 92.
  • the sloped sides 92 abut at least part of the ball 44 as it extends through an opening 20 in the plug and into the aperture 22 and this serves to retain the locking rod 24 within the slot 18.
  • the ball 44 When the ball 44 is received in the deepest part of the depression 90, the ball 44 does not extend beyond the confines of the plug 12 such that the plug 12 is allowed to rotate within the casing 14. However, in this position a portion of the ball 44 will still be received in the opening 20 in the plug 12 so that the locking rod 24 cannot be removed from the plug 12 in the unlocked position. In the unlocked position the key can also serve to retain the locking rod 24 within the slot 18.
  • Figures 8 to 10 show another embodiment of the invention in which the recess 42 is not formed within the cut-out 34, but instead is formed in a different part of the locking rod 24.
  • the cut-out 34 and the recess 42 respectively receive a first 44a and a second 44b ball.
  • the first ball 44a is held within the confines of the plug 12, in an opening 20 provided in the outer portion of the plug 12, and is retained in the opening in all positions of the lock 10.
  • the cut-out 34 moves relative to the ball 44a so that the ball 44a effectively travels between a front 36 and a rear 38 sloped wall, of the cut-out 34. This serves to retain the locking rod 24 within the plug 12.
  • the second ball 44b sits on the locking rod 24 and engages with the aperture 22 in the casing 14.
  • the first ball 44a abuts the rear sloped wall 38 of the cut-out 34 such that the locking rod 24 cannot be removed from the plug 12.
  • the unlocking shoulder 86 of the key A contacts the locking rod 24 and moves the locking rod 24 into the plug 12 until the stop shoulder 84 of the key A abuts the plug 12.
  • the inward movement of the locking rod 24 aligns the recess 42 with the aperture 22.
  • the second ball 44b is ejected into the recess 42 so that it no longer engages with the aperture 22 in the casing 14, allowing the plug 12 to rotate.
  • the front sloped wall 36 of the cut-out 34 is moved towards the first ball 44a.
  • the spacing of the recess 42 and the cut-out 34 may be such that the sloped wall 36 does not engage the first ball 44a when the recess 42 is aligned with the aperture 22.
  • the locking rod 24 can therefore be moved further into the plug 12 and past the unlocked position (for example by insertion of a non-complementary key), until the sloped wall 36 engages the first ball 44a in a further locked position.
  • Figures 11 to 14 show a further embodiment of the invention.
  • the casing 14 of the lock comprises an arced section 100 with an inner surface 102.
  • the arced section 100 is thicker than the casing 14 so that the inner surface 102 of the arc protrudes into the plug 12 and forms a fixed obstruction.
  • At the mid-point of the inner surface 102 of the arced section there is an aperture in the form of a notch 104.
  • a part 105 (which constitutes the locking means) of the locking rod 24 is engaged with the notch 104 which prevents the plug 12 from rotating, but permits axial movement of the locking rod 24.
  • a reduced diameter portion 106 of the locking rod 24 aligns with the notch 104. Since the reduced-diameter portion 106 of the locking rod 24 does not extend beyond the inner surface 102 of the arced section 100, the plug 12 is free to rotate. A channel (not shown) around the circumference of the plug 12 receives the arced section 100 and allows the plug 12 to rotate.
  • first and second reduced diameter portions may be provided in the locking rod, which provide first and second unlocked positions of the lock. This provides a master key facility, wherein a master key is able to align the second reduced diameter portion of the locking rod with the notch to enable rotation of the plug.
  • Figures 15a to 15d show a lock similar to that shown in Figure 4 but further including a master key facility.
  • a lock A comprises first 42a and second 42b recesses in the surface of the locking rod 24.
  • the first recess 42a is spaced from the front end 26 of the locking rod 24 by a distance x.
  • the unlocking shoulder 86 pushes the locking rod 24 into the plug 12 until the stop shoulder 84 abuts the plug 12, such that the first recess 42a is aligned with the aperture 22 and the ball 44 moves into the first recess 42a.
  • Figure 15b shows a different lock B with a complementary key B, not in accordance with the present invention, inserted.
  • lock B the first recess 42a is spaced from the front end 26 of the locking rod 24 by a distance y, which is greater than the corresponding distance x in lock A.
  • key A can only unlock lock A
  • key B can only unlock lock B.
  • the first 42a and second 42b recesses have a curved profile, and are separated by a flat section 110 of the locking rod 24.
  • the flat section 110 makes the lock more secure, since the ball 44 cannot easily be forced into one of the recesses in the absence of a complementary key.
  • a flat section is not provided between the recesses, and the recesses may adopt an angular or square profile.
  • Figures 15c and 15d respectively show the locks A and B with a master key M, not in accordance with the present invention, inserted.
  • the master key M has an unlocking shoulder 86.
  • the second recess 42b is aligned with the aperture 22 so that the ball 44 is moved into the second recess 42b.
  • the second recess 42b is spaced apart from the front end 26 of the locking rod 24 by the same distance z in each of the locks A and B, so that the master key M is able to unlock both locks.
  • the first 42a and second 42b recesses provide first and second unlocked position of the locks A and B, enabling both locks to be operated by a master key M.
  • the master key has an unlocking shoulder 86, which also provides the function of a stop shoulder.
  • the master key M is pushed into the lock until the shoulder 86 abuts the lock, which aligns the second recess 42b in the second unlocked position.
  • the master key M could be provided with separate unlocking and stop shoulders which are spaced apart by a distance such that when the master key M is inserted into the lock until the stop shoulder abuts the lock, the locking rod 24 is pushed into the lock by a distance which aligns the second recess 42b with the aperture 22.
  • FIGS 16A through F show a further embodiment of a lock 120 according to the present invention.
  • the lock 120 is similar in construction to the lock shown in Figures 11 to 14 and so like reference numerals will be employed as appropriate.
  • the lock 120 therefore has a casing 14 comprising an arced section 100 with an inner surface 102.
  • the arced section 100 is thicker than the casing 14 so that the inner surface 102 of the arc protrudes into the plug 12 and forms a fixed obstruction.
  • a part 105 (which constitutes the locking means) of a rectangular locking rod 122 is engaged with the notch 104 which prevents the plug 12 from rotating, but permits axial movement of the locking rod 122.
  • a reduced height portion 106 of the locking rod 122 aligns with the notch 104. Since the reduced height portion 106 of the locking rod 122 does not extend beyond the inner surface 102 of the arced section 100, the plug 12 is free to rotate.
  • a channel (not shown) around the circumference of the plug 12 receives the arced section 100 and allows the plug 12 to rotate.
  • alignment of the reduced height portion 106 with the notch 104 constitutes the unlocked position of the lock 122.
  • the locking rod 122 is provided in a channel 124 cut along the upper surface of the plug 12.
  • the channel 124 has a curved portion 126 gradually sloping inwardly from the upper surface of the plug 12 before extending in a generally flat portion 128 towards the free end of the plug 12.
  • the plug 12 includes a cylindrical aperture 130 disposed part-way along the flat portion 128, having a width greater than the flat portion 128 and extending from the upper surface of the plug 12 to the flat portion 128.
  • the locking rod 122 of the present invention has a stepped end 132 protruding from the lock 120.
  • the stepped end 132 comprises a transverse cut-out in the lower portion of the rod 122 to accommodate the stop shoulder 84 of the key 70 when the unlocking shoulder 86 is in contact with the protruding end of the locking rod 122 so as to move the lock to its unlocked position, shown in Figure 16B .
  • the locking rod 122 also includes a rectangular recess 134 along a portion of its lower surface.
  • a retainer in the form of a cylinder 136 is provided to fill the cylindrical aperture 130, the locking rod 122 is placed in the channel 124 such that the cylinder 136 is located within the recess 134 and a spring 138 is also provided within the recess 134 to act between the cylinder 136 and the front face of the recess 134.
  • the spring 138 will urge the locking rod 122 out of the plug 12 until the rear of the locking rod 122 abuts the cylinder 136 and as such the cylinder 136 will serve to retain the locking rod 122 in the lock 120.
  • the spring 138 When the locking rod 122 is urged by a suitable key 70 into the lock 120, the spring 138 will be compressed and the locking rod 122 will move along the channel 124 and will thereby move the part 105 out of the notch 104 so as to align the reduced height portion 106 with the notch 104 so that the plug 12 is not prevented from rotating. In this position, the lock 120 will be unlocked and the key 70 will be permitted to rotate the plug 12 within the casing 14.
  • FIG 17A and 17B shows a lock 140, that is a variant of the lock 120 shown in Figures 16A through 16F , having a key 150, not in accordance with the present invention, inserted therein.
  • a portion of the lock 140 is shown but the only difference between the lock 120 and the present lock 140 is that instead of the stepped end 132 of the locking rod 122 having a transverse cut-out in the lower portion of the rod 122, the stepped end 132 now comprises a partial transverse cut-out 142 down one side of the rod 122.
  • the key 150 is substantially the same as the key 70 shown in previous figures but in this case the key includes an unlocking shoulder 152 provided by a partial transverse side cut-out in the stop shoulder 154.
  • the cut-out is bounded by a curved bottom surface 156, a vertical side surface 158 and a vertical end surface constituted by the unlocking shoulder 152.
  • the handle 72 and shaft 74 of the key 150 are identical to those shown in Figure 3b .
  • FIGs 18A and 18B show a key 160, in accordance with the present invention, that is a variant of the key 150 shown in Figures 17A through 17C .
  • the differences between the key 160 and key 150 are that the partial transverse cut-out in the key 160 is bounded by a planar bottom surface 162 and that a corner cut-out 164 is provided along the length of the shaft 74.
  • a gap 166 is provided between the shaft 74 and the stop shoulder 154 in which the unlocking shoulder 152 is provided, the bottom surface of the corner cut-out 164 is aligned with the bottom surface 162 of the transverse cut-out and therefore acts an extension thereto.
  • the side surface of the corner cut-out 164 is aligned with the side surface 158 of the transverse cut-out and therefore acts an extension thereto.
  • the diagonally opposite corner of the shaft 74 is provided with an identical corner cut-out 164 and the diagonally opposite corner of the stop shoulder 154 also includes an identical partial transverse cut-out to form a diagonally opposite unlocking shoulder 152.
  • FIGs 19 through 19D show a lock 170 that is a further variant of the lock 140 shown in Figures 17A and 17B .
  • the locking rod 122 terminates at the end of the rectangular recess 134 so that the rear end of the locking rod 122 no longer abuts the cylinder 136 to retain the locking rod 122 in the lock 170.
  • the locking rod 122 is retained in the lock 170 by the arced section 100 of the casing 14 having an off-centre notch 104 such that a portion of the arced section 100 adjacent the notch 104 serves to retain the locking rod 122 in the lock 170.
  • This embodiment is advantageous since it allows the locking rod 122 to be inserted, removed or replaced without having to remove the entire lock 170 or plug 12 - all that is required is that the plug 12 is rotated so that the channel 124 is no longer partly obstructed by the arced section 100 and the locking rod 122 can be accessed.
  • This embodiment also comprises a second arced section 172 provided in the casing 14, opposite to the first arced section 100.
  • the second arced section 172 is identical to the first arced section 100 and is orientated such that the notch 174 in the second arced section 172 is diagonally opposite to the notch 104 in the first arced section 100.
  • FIG. 19D The lock of Figures 19 through 19D may be configured for use with the key 160 of Figures 18A and 18B .
  • a key 180 in accordance with the present invention, is employed which is substantially similar to the key 170 but includes curved (rather than planar) bottom surfaces 182 bounding each opposite partial transverse cut-out.
  • the partial traverse cut-outs 184 are provided on a first set of diagonally opposite corners of the key 180, while the corner cut-outs 164 along the shaft 74 are provided on the other set of diagonally opposite corners of the key 180.
  • An advantage of the lock 170 is that the key 180 can be extracted after the plug 12 has been rotated through 180° since, in this position, the second arced section 172 will serve to retain the locking rod 122 in the lock 170.
