Description
- The present invention relates to cylinder locks and more particularly to barrels therefor as specified in the pre-characterising portion of
claims 1 and 8. - Known cylinder locks employing a conventional barrel require the use of upper pins which bear against the locking pin and bias same toward the keyway. Thus the barrel is not self contained which is a disadvantage. Examples of such known cylinder locks are shown in DE-A-1 428 504 - in accordance with the pre-characterising portion of claim 1 - DE-B-2 924 990 - in accordance with the pre-characterising portion of claim 8 - and GB-A-1 223 142. The cylinder locks therein disclosed are each provided with a barrel having passages, with each passage receiving a lock pin. Located above each lock pin is an upper pin with the pins being rotatable about their longitudinal axis. In particular the use of upper pins increases the size of the locks. Still further, most cylinder locks do not offer a large number of possible lock combinations which has the disadvantage that the locks are more easily picked while it limits the number of combinations available to users.
- Where large combinations are available it has been found that these types of cylinder locks employ a large number of different parts and accordingly are generally expensive to manufacture due to their complexity.
- It is an object of the present invention to overcome or substantially ameliorate the above disadvantages.
- The present invention provides a barrel for a cylinder lock which does not employ upper pins, and the invention is characterised by the features defined in the characterising portions of
claims 1 and 8. - A preferred form of the present invention will now be described by way of example with reference to the accompanying drawings, wherein:
- Figure 1 is a schematic perspective parts exploded view of a barrel for a cylinder lock;
- Figure 2 is a schematic parts exploded view of a further barrel to that of Figure 1;
- Figure 3 is a schematic perspective view of a housing to receive the barrel of Figures 1 and 2;
- Figure 4 is a schematic side elevation of a key adapted to be used with the barrels of Figures 1 and 2 with the key engaged by locking pins;
- Figure 5 is a schematic perspective view of the key of Figure 4;
- Figures 6, 7 and 8 are schematic end elevations and side elevations of various key blanks which may be employed with the barrels of Figures 1 and 2; and
- Figure 9 is a schematic perspective view of a barrel and front portion of a cylindrical lock;
- Figure 10 is a schematic perspective view of a further barrel and front portion of a cylindrical lock;
- Figure 11 is a schematic plan view of a still further barrel body of a cylindrical lock;
- Figure 12 is a parts exploded schematic perspective view of a further lock barrel;
- Figure 13 is a side elevation of a locking pin used in the barrel of Figure 12;
- Figure 14 is a plan view of the pin of Figure 13;
- Figure 15 is a schematic side elevation of a key and locking pin; and
- Figure 16 is a plan view of the key of Figure 15.
- In Figure 1 there is schematically depicted a
barrel 10 of a cylinder lock, whichbarrel 10 is adapted to be located within thehousing 11 of Figure 3. Thebarrel 10 includes a generallycylindrical body 12 having end faces 13 and 14. Formed in thebody 12 is akeyway 15 which extends longitudinally inwardly from theface 14 to adjacent theface 13. Thekeyway 15 has a configuration adapted to receive a key similar to that of Figures 4 and 5, however it may be altered to fit any one of the keys depicted in Figures 6 to 9. - Extending inwardly from the outer cylindrical periphery of the
body 12 are a plurality ofbores 16 which are divided into two longitudinally extendingsets bores 16 are arranged in pairs consisting of a bore from each set. Slidably received within each bore is alocking pin 17, which locking pins are divided intosets locking pins plate 18 which in combination with the internal surfaces of thebores 16, restrict thelocking pins 17 to moving in a direction generally perpendicular to the longitudinal axis of thebody 12. Additionally eachpin 17 has a flat face which slidably abuts theplate 18 so as to prevent rotation of thepins 17 about the longitudinal axes. - The
body 12 is further provided with two longitudinally extendingrecesses 19 which are adapted to receivelocking bars 20 which havelocking projections 21. Thelocking bars 20 are biased to a radially outer position by means ofsprings 22. Thelocking bars 20 are slidably received within therecesses 19 so as to be movable from a radially inner position allowing rotation of thebarrel 10 to a radially outer position engaged within the grooves 23 (Fig. 3) formed on the internal surfaces of thehousing 11. In this radially outer position thebarrel 10 is prevented from rotating by thelocking bars 20. - Each of the
pins 17 is provided with arecess 24 which is dimensioned to receive alocking projection 21 so that upon location of therecesses 24 in the correct position, the corresponding locking projection is engageable therein. Additionally eachpin 17 may be provided with adummy recess 25 which is provided to hinder picking of the lock. Theprojections 21 pass throughpassages 161 extending from thebores 16. - Upon a key of correct configuration being inserted in the
keyway 15, each of thepins 17 is located so that thelocking projections 21 are receivable within therecess 24 thereby allowing thelocking bars 20 to move to a radially inner position. Thus thebarrel 10 may be rotated. If therecesses 24 are not all correctly aligned, then the locking bars are prevented from moving thus retaining thebarrel 10 in a locking position. As can be seen from Figures 1 and 3, thelocking bars 20 are provided withconverging surfaces 26 which cooperate with convergingsurfaces 27 forming thegroove 23 to force thelocking bars 20 radially inwardly. Thelocking pins 17 are biased to a position projecting inwardly of thekeyway 15 by means ofsprings 28 which bear against thelocking pins 17 and acover plate 29. - Turning now to Figure 2 wherein there is schematically depicted a barrel 30 which is of very similar construction to the
barrel 10 of Figure 1. The difference being that the barrel 30 has akeyway 31 provided with longitudinally extendingflutes 32 which again increases the number of combinations available for the lock. Additionally there is providedfurther pins 33 which are adapted to engage an annular groove formed on the internal surfaces of thehousing 11. Thesefurther pins 33 are adapted to retain the barrel 30 within thehousing 11 until a key of correct combination is inserted allowing retraction of thesefurther pins 33. Thepins 33 are slidably received withinpassages 34 formed in thebody 12 with aspring 35 being provided to bias thepins 33 to their radially outer position retaining the barrel 30 within thehousing 11. - It should be appreciated that the barrels of Figures 1 and 2 could have key slots having two or more key blades. In such cases the number of rows of locking pins would be increased.
- Turning now to Figures 4 to 10, and particularly Figures 4 and 5, there is schematically depicted a key 40 of generally U-shaped transverse cross-section so as to have upwardly extending
key blades 41 joined by abase 42. There is schematically illustrated in Figure 4 twolocking pins 17 engaged with the teeth of theblades 41 so that thepassages 24 are aligned thus allowing entry of thelocking projections 21. Thekey 40 is also provided with longitudinally extending flutes andridges 43 adapted to increase the number of combinations available to the lock. In should be particularly appreciated that theteeth 44 formed in theblades 41 are separated byvalleys 45 which may extend downwardly to a limit position adjacent thebase 42. By providing thekey 40 withblades 41 joined bybase 42, the valleys may extend to adjacent thebase 42 without the key 40 being weakened to an extent such that it is easily deformed during use. - A particular feature provided in the
key 40 is the leadingportion 46 which is substantially of a chisel configuration enabling thebarrel 10 to be self contained in that outer locking pins are not required. By providing the key 40 with the leadingportion 46, thelocking pins 17 may extend further into thekeyway 15. - A further advantage of the
key 40 is that thevalleys 45 are more easily formed since theblades 41 are in a spaced parallel relationship. - Turning now to Figures 7 and 8, there is schematically depicted a plurality of key configurations with each key including a
base 50 from which extend one or morekey blades 51 adapted to receive a key profile. In each instance the keys of Figures 6 to 10 are adapted such that valleys formed in theblades 51 may extend to adjacent thebase 50 without structurally weakening the key to an extent that it is easily damaged during normal use. Still further in each case the keys are provided with a leadingportion 52 of a chiselled configuration. - By providing two or
more blades 51, the number of possible combinations is increased. Accordingly, a barrel adapted to receive the key of Figure 6 would be provided with an additional set of locking pins and bores. - Turning now to Figure 9, there is schematically depicted the barrel 60 of a cylindrical lock. The barrel 60 has a
front face 61 which defines akey slot 63. Thekey slot 63 is shaped so as to accommodate a wide range of key configurations of the type suitable for the barrel 60. Thefront face 61 is further provided with a transversely extending slot which is adapted to receive a key selection member 64 which has akey slot 65 which is aligned with theslot 63 when the member 64 is located within theslot 62. By providing an assembly member 64, a standard barrel 60 may be provided with individual key combinations being selected by interchangeablekey selection members 65. - Turning now to Figure 10, the
barrel 66 is similar to that of Figure 11 in that is it provided with aremovable front portion 67. Further, thebarrel 66 is provided with akey slot 68 adapted to receive a large variety of key configurations which are suitable to be used with the barrel 60. Additionally, the barrel 60 is provided with a centralcylindrical aperture 73 adapted to receive acylindrical projection 74 forming part of thefront portion 67. Additionally, there is provided apassage 75 extending through thecylindrical projection 74 which is aligned withpassages 76 formed in thebarrel 66 to allow the insertion of apin 72 to retain thefront portion 67 in its operative position. - The
front portion 67 has akey slot 69 which is adapted to select a particular key configuration. Accordingly thebarrel 66 is adapted to be used as a standard barrel with particular key configurations being selected by thefront portion 67. - In Figure 11 the body 70 is of similar configuration to the previously described barrel bodies, however the
bores 71 which receive locking pins are square in transverse cross-section. The locking pins would be of a complementary cross-section so as to interact with thebores 71 to prevent rotation of the locking pins within thebores 71. - Now in regard to Figure 12 wherein there is depicted a
cylinder lock barrel 80 in parts exploded view, it can be seen that thebarrel 80 includes abody 81. Thebody 81 has two rows ofcylindrical holes 82 which are transversely aligned so as to be arranged in pairs. There is also formed in the body 81 aslot 83 which is adapted to slidingly receive side bars 84. Theholes 82 are adapted to slidingly receive lockingpins 85 which are each provided with aslot 86 which slidingly receives the projections 87 on the side bars 84. Additionally each lockingpin 85 has ahole 88 which also receive the projections 87. In Figure 14 one of the locking pins 85 is illustrated. - In operation of the above barrel, the
pins 85 are biased to engage the tooth profile of the key 89 which it is engaged within thekey slot 90. Thepins 85 are biased to engage the key 89 by means ofsprings 94. Thesprings 94 abut a cover plate 95 which is slidingly received within a slot formed in thebody 81. Accordingly theholes 82 are in communication with thekey slot 90. If the key 87 has the correct profile, then theholes 88 will line up along the side bars 84 to move radially inwardly of thebody 81 to allow the cylinder barrel to rotate. - It should be appreciated that the
pins 85 are prevented from rotation about their longitudinal axes by the sliding engagement of the projections 87 within theslots 86. Additionally the side bars are located within aslot 92 formed in thehousing 93 of the lock. Accordingly the side bars 84 prevent the rotation of the cylinder barrel until theholes 88 are longitudinally aligned to enable the side bars 84 to move radially inwardly. - Turning now to Figures 15 and 16 wherein there is schematically depicted a
single blade 100 which may form one of the blades of the keys described previously. Theblade 100 hasteeth 101 withkey surfaces 102 which are inclined both to the longitudinal axis of the key as well as the general plane of the key. Accordingly eachkey surface 102 would define a plane which intersects the general plane of theblade 100. Accordingly to minimise wear and to enable easy operation of the lock to be employed with theblade 100 the locking pins 103 would have a correspondingly angled key surface engaging theportion 104. With the above describedkey blade 100, the combinations available with the previously described keys is further expanded as the angles of thekey surface 102 may be altered to thereby alter the combination of the lock which would suit thekey blade 100.
