Definitions

  • the present invention relates to cylinder locks and more particularly to keys therefor.
  • a key blank of generally "V-shaped" transverse cross-section so as to provide two longitudinally extending transversely converging key blades joined by a longitudinal base.
  • 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 particularly the key of Figures 4 and 5, however it may be altered to fit any one of the keys depicted in Figures 6 to 9.
  • 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.
  • 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.
  • 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.
  • These further pins 33 are adapted to retain the barrel 30 within the housing 11 until a key of correct combination is inserted allowing retraction of these further pins 33.
  • 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.
  • FIG. 4 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 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.
  • 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 it is 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 70 extending through the cylindrical projection 74 which is aligned with passages 71 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 (which acts as a key selection member) 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 initial key blank 50 is provided with a blade portion 51 and a head portion 52.
  • the blade portion 51 has longitudinal recesses or ribs 53 which may be varied to alter the combination provided by the key. These recesses or ribs 53 would match the flutes 32 of Figure 2 or the configuration of the key slot of the key selection members 64 and 67 of Figures 6 and 7.
  • the head portion 52 is provided with recesses or holes 54 to securely engage a plastic key head.
  • the finished key 50B is formed by cutting key profiles in the blades 55 and then further bending the blades so as to provide the key 50B with a substantially "U-shaped" transverse cross-section. Additionally a plastic head would be securely located between the head portions 57.
  • the blank 50 is also provided with two grooves 57 which extend along the two longitudinal axes about which the blank 50 is bent.
  • the grooves 57 aid in the accurate bend of the blank 50 to form the intermediate blank 50A.
  • the grooves 57 are dimensioned so as to not be totally closed when the intermediate blank 50A is formed. The remaining unclosed part of the grooves 57 enables the easy formation of the key 50B.
