Definitions

  • 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.
  • 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.
  • FIG. 1 there is schematically depicted a barrel 10 of a cylinder lock, which barrel 10 is adapted to be located within the housing 11 of Figure 3.
  • the barrel 10 includes a generally cylindrical body 12 having end faces 13 and 14.
  • Formed in the body 12 is a keyway 15 which extends longitudinally inwardly from the face 14 to adjacent the face 13.
  • the keyway 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.
  • each pin 17 Extending inwardly from the outer cylindrical periphery of the body 12 are a plurality of bores 16 which are divided into two longitudinally extending sets 16A and 16B. Additionally the bores 16 are arranged in pairs consisting of a bore from each set. Slidably received within each bore is a locking pin 17, which locking pins are divided into sets 17A and 17B. The locking pins 17A and 17B are held in a spaced parallel relationship by a plate 18 which in combination with the internal surfaces of the bores 16, restrict the locking pins 17 to moving in a direction generally perpendicular to the longitudinal axis of the body 12. Additionally each pin 17 has a flat face which slidably abuts the plate 18 so as to prevent rotation of the pins 17 about the longitudinal axes.
  • the body 12 is further provided with two longitudinally extending recesses 19 which are adapted to receive locking bars 20 which have locking projections 21.
  • the locking bars 20 are biased to a radially outer position by means of springs 22.
  • the locking bars 20 are slidably received within the recesses 19 so as to be movable from a radially inner position allowing rotation of the barrel 10 to a radially outer position engaged within the grooves 23 (Fig. 3) formed on the internal surfaces of the housing 11. In this radially outer position the barrel 10 is prevented from rotating by the locking bars 20.
  • Each of the pins 17 is provided with a recess 24 which is dimensioned to receive a locking projection 21 so that upon location of the recesses 24 in the correct position, the corresponding locking projection is engageable therein. Additionally each pin 17 may be provided with a dummy recess 25 which is provided to hinder picking of the lock.
  • the projections 21 pass through passages 161 extending from the bores 16.
  • each of the pins 17 is located so that the locking projections 21 are receivable within the recess 24 thereby allowing the locking bars 20 to move to a radially inner position.
  • the barrel 10 may be rotated. If the recesses 24 are not all correctly aligned, then the locking bars are prevented from moving thus retaining the barrel 10 in a locking position.
  • the locking bars 20 are provided with converging surfaces 26 which cooperate with converging surfaces 27 forming the groove 23 to force the locking bars 20 radially inwardly.
  • the locking pins 17 are biased to a position projecting inwardly of the keyway 15 by means of springs 28 which bear against the locking pins 17 and a cover plate 29.
  • FIG. 2 wherein there is schematically depicted a barrel 30 which is of very similar construction to the barrel 10 of Figure 1.
  • the barrel 30 has a keyway 31 provided with longitudinally extending flutes 32 which again increases the number of combinations available for the lock.
  • further pins 33 which are adapted to engage an annular groove formed on the internal surfaces of the housing 11.
  • the pins 33 are slidably received within passages 34 formed in the body 12 with a spring 35 being provided to bias the pins 33 to their radially outer position retaining the barrel 30 within the housing 11.
  • 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.
  • a key 40 of generally U-shaped transverse cross-section so as to have upwardly extending key blades 41 joined by a base 42.
  • the key 40 is also provided with longitudinally extending flutes and ridges 43 adapted to increase the number of combinations available to the lock.
  • the teeth 44 formed in the blades 41 are separated by valleys 45 which may extend downwardly to a limit position adjacent the base 42.
  • a particular feature provided in the key 40 is the leading portion 46 which is substantially of a chisel configuration enabling the barrel 10 to be self contained in that outer locking pins are not required. By providing the key 40 with the leading portion 46, the locking pins 17 may extend further into the keyway 15.
  • a further advantage of the key 40 is that the valleys 45 are more easily formed since the blades 41 are in a spaced parallel relationship.
  • each key including a base 50 from which extend one or more key blades 51 adapted to receive a key profile.
  • the keys of Figures 6 to 10 are adapted such that valleys formed in the blades 51 may extend to adjacent the base 50 without structurally weakening the key to an extent that it is easily damaged during normal use.
  • the keys are provided with a leading portion 52 of a chiselled configuration.
  • the barrel 60 has a front face 61 which defines a key slot 63.
  • the key slot 63 is shaped so as to accommodate a wide range of key configurations of the type suitable for the barrel 60.
  • the front face 61 is further provided with a transversely extending slot which is adapted to receive a key selection member 64 which has a key slot 65 which is aligned with the slot 63 when the member 64 is located within the slot 62.
  • a standard barrel 60 may be provided with individual key combinations being selected by interchangeable key selection members 65.
  • the barrel 66 is similar to that of Figure 11 in that is it provided with a removable front portion 67. Further, the barrel 66 is provided with a key 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 central cylindrical aperture 73 adapted to receive a cylindrical projection 74 forming part of the front portion 67. Additionally, there is provided a passage 75 extending through the cylindrical projection 74 which is aligned with passages 76 formed in the barrel 66 to allow the insertion of a pin 72 to retain the front portion 67 in its operative position.
  • the front portion 67 has a key slot 69 which is adapted to select a particular key configuration. Accordingly the barrel 66 is adapted to be used as a standard barrel with particular key configurations being selected by the front portion 67.
  • 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 the bores 71 to prevent rotation of the locking pins within the bores 71.
  • the barrel 80 includes a body 81.
  • the body 81 has two rows of cylindrical holes 82 which are transversely aligned so as to be arranged in pairs.
  • the holes 82 are adapted to slidingly receive locking pins 85 which are each provided with a slot 86 which slidingly receives the projections 87 on the side bars 84.
  • each locking pin 85 has a hole 88 which also receive the projections 87.
  • one of the locking pins 85 is illustrated.
  • the pins 85 are biased to engage the tooth profile of the key 89 which it is engaged within the key slot 90.
  • the pins 85 are biased to engage the key 89 by means of springs 94.
  • the springs 94 abut a cover plate 95 which is slidingly received within a slot formed in the body 81. Accordingly the holes 82 are in communication with the key slot 90. If the key 87 has the correct profile, then the holes 88 will line up along the side bars 84 to move radially inwardly of the body 81 to allow the cylinder barrel to rotate.
  • the pins 85 are prevented from rotation about their longitudinal axes by the sliding engagement of the projections 87 within the slots 86. Additionally the side bars are located within a slot 92 formed in the housing 93 of the lock. Accordingly the side bars 84 prevent the rotation of the cylinder barrel until the holes 88 are longitudinally aligned to enable the side bars 84 to move radially inwardly.
  • FIG. 15 and 16 wherein there is schematically depicted a single blade 100 which may form one of the blades of the keys described previously.
  • the blade 100 has teeth 101 with key surfaces 102 which are inclined both to the longitudinal axis of the key as well as the general plane of the key. Accordingly each key surface 102 would define a plane which intersects the general plane of the blade 100. Accordingly to minimise wear and to enable easy operation of the lock to be employed with the blade 100 the locking pins 103 would have a correspondingly angled key surface engaging the portion 104.
  • the combinations available with the previously described keys is further expanded as the angles of the key surface 102 may be altered to thereby alter the combination of the lock which would suit the key blade 100.
