VaO 00 5 Padlocks of a known type are formed of a body, a shackle and a lock assembly VaO o having a keyway for receiving a key. In use, operation of the key in the keyway Cl enables rotation of the lock assembly whereby a leg of the shackle can be released from the padlock body. The shackle can then be passed through objects to be secured together (such as a gate and the bolt used to hold the gate shut), the leg of the shackle replaced in the body of the padlock assembly, and locked in place.

Removal of the shackle leg, and hence opening of the gate, cannot be performed without the correct key or by unauthorised means.

A single key may operate the padlock, or there may be a key, individual to the padlock, and a master key that can open more than one padlock. It is desirable in establishments using a large number of padlocks to secure items, buildings or areas, that these padlocks be operable by the same key, the same type of lock, or to be operable by the same master key. It may be that security is breached and a key or master key falls into the hands of an unauthorised person necessitating the rapid replacement of all the padlocks in order that security be maintained. Replacement of all the padlocks used by a person or establishment is clearly expensive and undesirable.

There have been developed means for replacement of the lock assembly of a padlock without the need to replace the whole padlock assembly. Known means of lock assembly removal includes removal of a screw, accessible through the recess for the second leg of the shackle, only when the padlock is in the open position. In known padlocks, for example as in US 5,174,136 THWING, removal of the screw can release a cylinder retainer which would otherwise maintain the lock assembly COMS ID No: SBMI-05099570 Received by IP Australia: Time 17:23 Date 2006-10-19 19/10/2006 17:13 19/0/20517:3 hrysilIlou Law (812) 99534755 31/54 13378.doc IND 2 o within the body of the padlock. Once the screw is released, the lock assembly can be separated from the cylinder retainer and hence released from the padlock body.

Known methods of lock assembly removal are unsatisfactory because, especially in the case of pin tumbler locks, the pins and springs tend to fall out of the padlock IND 5 once the locking assembly is removed. Further problems with known means, are 00 that removal of the lock assembly barrel is slow and can be a difficult or complex 0 procedure.

0 Referring first to Figures 1 to 8, padlock assembly 10 has padlock body 12 and C) shackle 14. Shackle 14 has a U-shaped portion 16 connecting first shackle leg 18, having end 20, and second shackle leg 22, having end 24. Shackle 14 may be made INO 5 of stainless steel or other suitable material. Although shackle 14 is described as U- 00 shaped, the shackle may take any suitable form, such as C-shaped or having squared corners. Padlock body 12 may be made of machined brass, steel or other suitable material.

cxl Second shackle leg 22 has shackle ball recess 26 close to end 24, facing towards first shackle leg 18. First shackle leg 18 has shackle ball recess 28, facing towards second shackle leg 22 and level with shackle ball recess 26 on second shackle leg 22.

Locking assembly 30 lies within padlock body 12, locking assembly 30 having body 3 1, keyway 32 (at one end of the body 3 1) and projection 34 (at the other end of body 31). Projection 34 is configured so as to act on shackle balls 36 and 38 whereby rotation of the locking assembly 30 translates rotation to projection 34, so that shackle balls 36 and 38 can be moved between a locked and unlocked position.

In the locked position, projection 34 maintains shackle balls 36 and 38 in their respective shackle ball recesses 26 and 28. In the unlocked position, projection 34 is rotated so that shackle balls 36 and 38 can move out of shackle ball recesses 26 and 28 to lie within padlock body 12, enabling withdrawal of shackle 14 from padlock body 12. In the unlocked position, shackle balls 36 and 38 lie in suitably configured recesses (not shown) in padlock body 12. Projection 34 is illustrated as a flat bar, but numerous suitable configurations may be used, such as a recessed cam or other means to act on shackle balls 36 and 38. Shackle balls 36 and 38 may be steel spheres or any other suitable configuration that can, with projection 34, act between a locked and unlocked position.

INO 5 Six rows of driver pins 40 and key pins (not shown) lie within bores 44, key pins 00 (not shown) also protruding into pin holes 43 (refer Figures 34 to 36) in the locking 0N assembly body 3 1. The position of the tops of bores 44 is illustrated in particular in INO Figure 2. Springs 46 lie in bores 44 acting on each driver pin 40 so as to bias driver o pins 40 and the key pins (not shown) towards the pin holes 43 in the locking i0 assembly In a known manner, when a suitable key (not shown) is inserted into keyway 32, the particular undulations of the key blade aligns the key pins (not shown), which are of various lengths, with the shear line (not shown) whereby locking assembly can be rotated relative to padlock assembly body 12.

In Figures 1 to 4, locking assembly 30 has been operated by a suitable key (not shown) and rotated to align keyway 32 with alignment point 47. Alignment of keyway 32 with alignment point 47 can. only happen after removal of the retaining pin as discussed below. Figure 4 illustrates the detail of area H of Figure 3 and in particular illustrates alignment point 47. Locking assembly 30 can only be removed from padlock body 12 if the locking assembly 30 has first been released and rotated counterclockwise to align keyway 32 with alignment point 47.

Padlock body 12 has first shackle recess 48 (refer Figure 6) and second shackle recess 50 configured to receive first shackle leg 18 and second shackle leg 22, respectively. Shackle spring 52 lies in the first shackle recess 48 (refer Figure 6) acting to bias first shackle leg 18 out of padlock body 12. First shackle leg 18 is held in first shackle recess 48 while second shackle leg 22 is out of second shackle COMS ID No: SBMI-05099570 Received by II' Australia: Time 17:23 Date 2006-10-19 19/10/2006 17:14 19/0/0001714ChrysilIlou Law (812) 99534755 39/54 I 5378.duc INO o recess 50 and in this position first shackle leg 18 can rotate so that second shackle leg 22 can be swung out of the way to expose second shackle recess Referring to Figure 5, Figure 6 and Figure 7, in particular, it can be seen that when second shackle leg 22 is swung out of the way to expose second shackle recess INO 5 part of shackle ball 36 and the position of a removable grub screw 54 can be seen.

00 INO Grub screw 54 is configured to fit into grub screw recess 56 in second shackle 0 recess 50 so as to act on retaining pin 58. Retaining pin 58 is free to move within SN retaining bore 60 (see Figures 34 to 37) before installation of grub screw 54.

Cxl Referring to Figures 9 to 14, these Figures illustrate padlock assembly 10 with locking assembly 3 0 in a locked position with both shackle legs 18 and 22 installed in their respective shackle recesses 26 and 28. Shackle balls 36 and 38 are being held in their respective shackle ball recesses 26 and 28 by projection 34 on tbe end of locking assembly body 3 1. As illustrated in particular in Figure 10 the configuration of projection 34 maintains shackle balls 36 and 38 in their respective shackle ball recesses 26 and 28 so that removal of shackle 14 by unauthorised means is prevented.

The orientation of keyway 32 in the locked position for this embodiment is in line with line A-A, as shown in Figure 13. The particular configuration of keyway 32 for locking, unlocking and rotation of the locking assembly may be varied from that described without diverging from the scope of the invention.

Grub screw 54 can be seen in situ in grub screw recess 56 in Figures 14 and 15 in particular. Grub screw 54 can be seen to act on retaining pin 58 to maintain it in retaining pin bore 60 (see Figures 34 to 37). When grub screw 54 and retaining pin 58 are in the locked position, locking assembly 30 is held, by the acting of retaining pin 58 on locking assembly 30, witbin padlock body 12 so that removal of locking assembly 30 is prevented. Further, retaining pin 58 limits rotation of locking COMS ID No: SBMI-05099570 Received by IP Australia: Time 17:23 Date 2006-10-19 19/10/2006 17:14 19/0/0051714Chrysil lou Law (812) 99534755 40/54 15378.doc o assembly 30, when a suitable key is inserted and key pins (not shown) aligned with the shear line, to 90 degrees rotation clockwise and back again.

Use of a suitable key (not shown) in keyway 32 will cause key pins (not shown) to be aligned with the shear line, as described above to allow rotation of locking INO 5 assembly 30 relative to padlock body 12. Such rotation is translated to projection 00 34 which is rotated to a position whereby shackle balls 36 and 38 are no longer 0N maintained in shackle ball recesses 26 and 28 but instead lie in recesses (not INO shown) in padlock body 12, each in communication with first shackle recess 48 or o second shackle recess 50. Locking assembly recess 78 (refer Figure 33) is also in communication with the recesses (not shown). Once shackle balls 36 and 38 are able to move out of their respective shackle ball recesses 26 and 28, shackle 14 can be retracted away from padlock body 12 so that second shackle leg 22 can be moved clear of second shackle recess Groove 62 can be seen most clearly in Figures 9, 10 and 14 which illustrate the locked position. Groove 62 works with shackle pin 64 in the unlocked position to prevent first shackle leg 18 being totally released from padlock body 12. Groove 62 defines two stop positions so that, as first shackle leg 18 is pushed against shackle spring 52, movement beyond first stop position 66 is prevented. When locking assembly 30 releases the shackle 14 from padlock body 12, first shackle leg 18 is prevented from being released from padlock body 12 beyond a second stop point 68. A shackle pin access point may be used to disable shackle pin 64 and allow shackle 14 to be totally removed from padlock body 12.

Referring to Figures 16 to 2 1, it can be seen that a suitable key (not shown) has been used to align the key pins (not shown) with the shear line so that locking assembly 30 can be rotated relative to padlock body 12. Shackle 14 has been released from padlock body 12 by release of shackle balls 36 and 38 from shackle ball recesses 26 and 28, allowing shackle spring 52 to bias shackle 14 away from padlock body 12. Shackle leg 22 can then be removed from padlock body 12 and COMS ID No: SBMI-05099570 Recived by IP Australia: Time 17:23 Date 2006-10-19 19/10/2005 17:14 19/0/0081714Chryslllou Law (812) 99534755 41/54 15378.doc INO 12 0 o swung away to expose second shackle recess 50. Grub screw 54 has been removed through use of a suitable tool, so that retaining pin 58 is free to move under gravity o within retaining pin bore 60 (see Figures 34 to 37). The release of retaining pin 58 ON allows locking assembly 30 to rotate 360 degrees clockwise or counterclockwise relative to padlock body 12, rather than being limited to 90 degrees clockwise and INO back again when retaining pin 58 is held in place.

0 Figures 16 to 21 show padlock body 12 with second shackle leg 22 released and INO swung aside to expose second shackle recess 50 and grub screw 54 removed to o enable release of retaining pin 58 so that locking assembly 30 can be rotated freely.

a Remover 70 has an ann 72 and a body part 74 adapted so that arm 72 can be pushed into remover recess 76 while body part 74 of remover 70 surrounds padlock body 12. Remover recess 76 lies close to and under second shackle recess 50 and is in communication with locking assembly recess 78 (refer Figure 33).

Referring to Figures 22 to 33, remover 70 is shown inserted into remover recess 76 so that arm 72 can act on locking assembly body 3 1. Locking assembly 30 is free to move as grub screw 54 has been removed and retaining pin 58 released so tat, under gravity, the retaining pin 58 moves away from the locking assembly Therefore, as the remover 70 is pushed against the locking assembly body 31 locking assembly 30 is pushed out of padlock body 12. As arm 72 passes through remover recess 76 into locking assembly recess 78 (refer Figure 33), arm 72 covers bores 44 so as to maintain driver pins 40 and springs 46 within padlock body 12.

Use of remover 70 is particularly advantageous since driver pins 40 are maintained in padlock body 12 to allow replacement of locking assembly 30 and key pins (not shown) without the need to replace or reposition driver pins 40 and springs 46.

Body 74 of remover 70 is configured in the illustrated embodiment so as to slide over the top of the padlock body 12, but any suitable configuration for body 74 may be used. Remover 70 may be made of bent steel or any other suitable material.
