Definitions

  • the present invention relates to a cylinder lock unit of the kind indicated in the preamble of claim 1.
  • the cylinder lock unit comprises a housing with an upper part and lower part,
  • the invention also relates to a cylinder lock unit of the above-defined kind, in combination of a key for unlocking the cylinder lock unit, said key comprising a grip portion and a key blade.
  • Such lock and key systems, cylinder lock units, and keys are frequently used in locking systems with a large number of lock units serving e.g. as door locks.
  • the cylinder lock core includes two side bars, one on each lateral side of the keyway, and also a locking segment which is movable relative to the side bar and the lock shell in response to the insertion of a key blade having a uniquely configured camming projection.
  • the side bars extend along substantially the whole length of the key plug.
  • EP 1240 399 A1 discloses an electromechanical cylinder lock with a side bar locking mechanism, wherein an electric motor and an actuator are housed at the back region of the cylinder core unit.
  • a cylinder lock unit is known from WO 2012/039671 A1 .
  • the main object of the present invention is to further increase the security and provide a cylinder lock unit with a high security side locking mechanism which is very difficult to manipulate so as to open the lock without using a properly cut key and which will also permit the key plug to possibly accommodate an extra lock component in the back region of the key plug, e.g. a part of a torque transferring connection, a blocking mechanism for blocking full insertion of a key blade which is not correctly cut, or an electronic component which facilitates the functioning of the lock unit.
  • the present international patent application relates to a further development of an invention for which a US patent application and an international patent application ( PCT/EP2018/062713 ), had already been filed at the filing date of the present application, but those earlier patent applications had not been published as of the filing date of the present application.
  • the further development is different from the one disclosed in the earlier applications, the novelty being that the "shell" of the lock unit (with the terminology used in the earlier applications) is integrated with or is permanently retained in the housing of the lock unit, and there is no division into an external housing and an internal, exchangeable lock "core".
  • the housing and the overall structure is more like a lock unit as disclosed in the US patent specification 8,720,241 (Widén), the housing being divided into an upper part with locking pins and a lower part with a bore accommodating a rotatable key plug.
  • Said at least one side locking mechanism comprises a longitudinal row of at least two side locking tumblers, each interacting with the lower part of the housing, either directly or indirectly via a side bar, in case the at least two coded side locking tumblers interact directly with the lower part of the housing, each such coded side locking tumbler is movable between a releasing confined position, where it is totally confined within the key plug, and at least one locking position, where it projects radially outside the key plug so as to fit into at least one recess in said housing and to engage with the housing and prevent rotation of the key plug, or in case the at least two coded side locking tumblers interact with the lower part of the housing via a side bar, which forms a part of said coded side locking mechanism and is located at the cylindrical outer circumference of the key plug so as to engage with an associated groove in said cylindrical bore of the housing, said side bar Is configured to fit into and engage with at least one coded recess in said tumbler in a releasing retracted position permitting rotation of the key plug, each
  • the relatively short front region of key plug is rather compact and preferably substantially solid, except for the keyway, the cavities for the locking pins and any recesses and holes for accommodating the side locking mechanism or mechanisms.
  • the length of the front region of the key plug, where the at least one side locking mechanism is located in its entirety, is thus rather short, e.g. 50%, about 40% or about 30% of the total length of the key plug. Nevertheless, thanks to the compact structure of the side locking mechanism, it can still provide a very large number of code combinations and a high security for the cylinder lock core.
  • each longitudinal row of side locking tumblers on one or both lateral sides of the key plug, may comprise at least two and preferably at least three (or even more) side locking tumblers.
  • the additional lock component possibly accommodated in the back region of the key plug, on each lateral side of the keyway may form a part of the torque transferring connection, e.g. a threaded hole for engaging with a fastening screw being connected to a door locking mechanism in the associated lock unit, or a blocking device for preventing the full insertion of an incorrectly cut key blade, or an electronic device for assisting in the proper functioning of the cylinder lock unit.
  • a threaded hole for engaging with a fastening screw being connected to a door locking mechanism in the associated lock unit
  • a blocking device for preventing the full insertion of an incorrectly cut key blade
  • an electronic device for assisting in the proper functioning of the cylinder lock unit.
  • the cylinder lock unit as defined above may be provided in combination with a key for unlocking the cylinder lock unit, the key comprising a grip portion and a key blade, wherein
  • a first embodiment of the lock unit 100 of the invention is shown in Figs. 1, 2a, 2b , 3, 4 , 5a, 5b, 5c and 5d , including a cylindrical housing 200 with a rotatable key plug 300, and an associated key 40.
  • the cylindrical housing 200 has a threaded rear end portion and a slightly conical front end flange.
  • the lock unit 100 is normally permanently mounted in a door or the like in order to cooperate with a door locking mechanism, as is well known per se.
  • the cylindrical housing 200 includes an upper, solid part 220 and a lower part 240 forming a cylindrical bore accommodating a rotatable key plug 300.
  • the rotatable key plug 300 is formed in one piece and is adapted to transfer a torque to a locking mechanism when the plug Is rotated.
  • a torque transferring connection including a cam member 151 which is secured to the key plug 300 by means of two fastening screws 152a, 152b, which engage with threaded holes in a back region L1 of the key plug, on each side of a keyway 320.
  • the torque transferring connection may be formed by other mechanical means, e.g. with a recess in the rear end of the key plug being coupled to a mating member forming a part of a locking mechanism in a door or some other object to be locked in a closed position. If so, the back region L1 of the key plug may be used for some other lock component, as indicated above. It is also possible to leave the back region of the key plug as a massive material portion, on each lateral side of the key way, as indicated in fig. 13c .
  • the upper, solid part 220 of the housing 200 has a central row of parallel cavities or holes 221a, 221b, 221c, 221d, 221e, 221f and 221g, the number of cavities being seven in this particular embodiment. As will be shown below, other normal embodiments are provided with six such cavities in a central row.
  • a longitudinal cover plate 222 will normally cover the holes 221a, etc. from above and keep a corresponding number of upper and lower locking pins 231a, etc., 232a, etc. and associated springs 235a, etc. in place.
  • the key plug can also be seen in Figs. 3,4 , 5a, 5b, 5c and 5d .
  • the outer diameter of the cylindrical key plug is slightly smaller than the inside diameter of the bore in the lower part 240 of the housing, so that the key plug can rotate in relation to the housing 200.
  • the possible rotary motion of the key plug is dependent on the positions of lower locking pins 231a, 231b, 231c, 231d, 231e, 231f, 231g shown in Fig. 2a and being movable in corresponding vertical cavities or holes 331a, 331b, 331c, 331d, 331e, 331f, 331g arranged in a central longitudinal row in the upper part of the key plug 300.
  • the central row of corresponding cavities 331a, 331b, 331c, 331d, 331e, 331f, 331g will accommodate the lower locking pins 231a, 231b, 231c, 231d, 231e, 231f, 231g.
  • a correctly cut key 40 will operate the cylinder lock unit so as to rotate the key plug 300 and turn the rear cam 151.
  • the back region (L1 in fig. 5d ) of the key plug 300 is relatively long, viz. at least 50% of the total length (L1 +FR1) of the key plug, measured from the back end up to a front end flange 310, whereas the front region (FR1 in fig. 5 d) of the key plug is relatively short, viz. at most 50 % of the full length thereof.
  • the front region FR1 should be long enough to accommodate a side locking mechanism including a longitudinal row of at least two side locking tumblers.
  • the back region (L1) of the key plug serves to accommodate the rear part of the central row of holes 331a - 331g above the keyway 320, possibly also an additional lock component, which may be a part of the torque transferring connection, such as the fastening screws 152b on either side of the keyway, or a blocking mechanism which will prevent the full insertion of an incorrectly cut key blade, or an electronic component which will facilitate or assist in the proper functioning of the lock unit.
  • an additional lock component which may be a part of the torque transferring connection, such as the fastening screws 152b on either side of the keyway, or a blocking mechanism which will prevent the full insertion of an incorrectly cut key blade, or an electronic component which will facilitate or assist in the proper functioning of the lock unit.
  • the key plug 300 is provided with a side locking mechanism which is located on at least one lateral side of the keyway 320 and which is confined entirely within the front region FR1 located longitudinally in front of the back region L1.
  • this front region FR1 is substantially solid, except for the keyway, the cavities for the lower locking pins and any recesses and holes for accommodating the side locking mechanism itself.
  • the side locking mechanism comprises at least two independently movable side locking tumblers providing a high security mechanism with at least three different code positions for each locking tumbler and a plurality of different code combinations for the side locking tumblers.
  • the side locking mechanism includes three coded side locking tumblers 351a, 351b, 351c ( figs. 2a and 5a ) which are arranged in a row at one side of the keyway 320 of the key plug 300, in the solid front region thereof.
  • the three locking tumblers are located entirely within this front region and also radially inside the lower part 240 of the housing.
  • This location of the side locking mechanism 351a, 351b, 351c has the advantage that it will interact mainly with the lower part 240 of the housing in associated recesses or holes 242 ( fig. 2a and fig. 4 ), next to the front end flange 310 of the key plug 300.
  • Other embodiments are possible, as will be described below.
  • the three side locking tumblers 351a, 351b, 351c are biased by springs 361a, 361b, 361c (collectively denoted 361a - 361c in Fig. 2a ) in associated vertical cavities or holes 371a, 371b, 371c (collectively denoted 371a-371c in Fig. 4a) at some lateral distance from the keyway 320 so as to project into the keyway with a projecting finger which will cooperate with a wave-like side code pattern 41 on the key blade of the associated key 40 ( fig. 2b ).
  • the locking tumblers 351a, etc. will move up and down in response to their contact with the side code pattern 41.
  • the lower ends of the coded side locking tumblers 351a, etc. will then interact with the associated recesses or holes 242 in the lower part 240 of the housing 200.
  • a number of V-shaped bittings at the upper edge portion 42 of the key 40 will interact with the central row of locking pins 231a, etc. Only when all of the lower and upper locking pins 231a, etc. and 232a, etc. and the three side locking tumblers 351a, etc. are correctly positioned within the circumference of the key plug 300, will it be possible to turn the key 40 so as to rotate the key plug 300 and unlock the cylinder lock unit.
  • the side tumblers 351a, etc. are movable independently of the central locking pins 231a, etc.
  • the side locking mechanism 351 will provide a high security for the cylinder lock core.
  • the side locking tumbler 351b is located in its totally retracted position within the key plug, where both of its ends are located at the shear line between the key plug 300 and the surrounding lower part 240 of the housing, and the central pin 231f is also located with its upper end being located flush with the shear line. In this position, the key plug can be rotated or turned, provided that all other central pins and coded side locking tumblers are also confined within the key plug.
  • a modified version of the first embodiment as shown in Fig. 6 , there are four side locking tumblers in a longitudinal row, in associated holes 371a, 371b, 371c, 371d.
  • the back region L1 and the front region FR1 of the key plug are just as long as in the previous embodiment.
  • a second embodiment illustrated in Figs. 7a, 7b, 7c and 7d , the structure is similar to the first embodiment (all the reference numerals starting with the digit 4 instead of 3), but here there is a row of coded side locking tumblers on each side of the keyway 420, each such row consisting of two independently movable side locking tumblers 451a, 451b and 461a, 461b, respectively.
  • Each side locking tumbler will interact with the surrounding lower part of the housing in the same way as shown in Fig. 4 .
  • the back region L2 of the key plug 400 is somewhat longer in this second embodiment, and the front region FR2 is shorter, the total length L2 + FR2 being the same as in Fig. 5d .
  • a modified version of the second embodiment shown in Figs. 8a, 8b, 8c and 8d , the structure is exactly the same as in the one shown in Figs. 7a , etc., except that the number of central locking pins 231a', ...231f' ( Fig. 8c ) in the key plug 400' is six rather than seven and the total length of the key plug is a little shorter. Still, the length of the back region L2' is slightly more than half of the length of the key plug.
  • a third embodiment shown in Figs. 9a, 9b, 9c, 9d, 9e, 9f, 9g, 9h and Fig. 10 , the number of central locking pins is again seven, like in most of the previous embodiments, but the side locking mechanism is different, with only two side locking tumblers on one side of the key plug 500 only, these two side locking tumblers 551a, 551b cooperating with a relatively short side bar 580 ( Fig. 9d ).
  • Such a side locking mechanism with a side bar is known per se, but not in the context of cylinder lock unit having a key plug with a back region being reserved for a possible extra lock component, e.g.
  • the side bar 580 is normally held in a longitudinal recess or groove 243 (see Fig. 9a ) by a spring 581 (see Fig. 9d ), located between the two side locking tumblers to save longitudinal space, in a position where it projects sideways outside the contour of the key plug 500. In this position, the side bar will register with the corresponding groove 243 in the lower part 240 of the housing 200 and thereby effectively lock the key plug against rotation.
  • the side bar 580 can be moved sideways, against the action of the spring 581, into a retracted position where it is no longer seated in the groove 243.
  • the side bar 580 will be retracted and permit rotation of the key plug 500.
  • a projecting lug 580a of the sidebar will find its way into a coded recess 555 in the cylindrical surface of the side locking tumbler 551b. This interaction will be seen clearly in the enlarged view in Fig.
  • the side locking mechanism will provide a high degree of security, since it is difficult to manipulate the side locking tumblers 551a, 551b so as to release the lock.
  • the back region of the key plug 500 may have a greater length L3, as shown in Fig. 9h , leaving only a relatively short front region FR3.
  • each side locking tumbler can interact in different ways with the side bar, either by way of rotating along its axis or being non-rotatable and having a longitudinally displaced finger.
  • the side locking tumbler 651b can rotate between two rotary end positions, as indicated by the arrow R.
  • a material portion 655, between two adjacent recesses 656,657 in the cylindrical surface of the side locking tumbler can fit into a corresponding slot 680a in the side bar 680.
  • the code combinations for each locking tumbler 651b will be 6 or higher.
  • the code pattern at the side of the key must be configured to accommodate for two or three different pivotal positions of the transverse finger 654.
  • the transverse finger 754 of the side locking tumbler 751b is longitudinally displaced (along the longitudinal axis of the keyway of the key plug) into one of three coded positions. Accordingly, with several possible levels of the recesses 755 at the cylindrical surface of the tumbler, there will also be a large number of code combinations for each side locking tumbler, e.g. 9 or higher.
  • a modified version of the third embodiment shown in Figs. 12a, 12b, 12c, 12d , there are three side locking tumblers 951a, 951b, 951c (on one side of the keyway 920 of the key plug 900) which interact with a somewhat longer side bar 980, biased by springs 981.
  • a fourth embodiment shown in Figs. 13c , there are two relatively short side locking mechanisms, one on each side of the keyway and each having a side bar 880, adjacent to the front end flange of the key plug 800.
  • This is a favorable embodiment with a very high number of code combinations and yet a very compact structure confined within a rather small part (less than 20%) of the total length of the key plug.
  • the back region has a relatively long length L2, being massive except for the rear part of the central row of holes or cavities, and the front region FR2 is relatively short, but if necessary, the front region of the key plug may be just as short as in the embodiment shown in Fig. 9h (FR3).
  • a fifth embodiment is shown in Figs. 13a and 13b where the key plug 800', in its solid front end region FR1, is provided, on each lateral side of the keyway, with a row of four side locking tumblers 851a', 851b', 851c', 851d' cooperating with an associated side bar 880'.
  • the side locking mechanisms are arranged on both lateral sides of the keyway, each with four side locking tumblers in a row, the result will be a very large number of code combinations.
  • Figs. 13b shows also the housing for the fifth embodiment, It is similar to the one shown in Fig. 2a , although it is adapted to the arrangement with two side bars 880'.
  • each side bar 880' is seated, in its locking position, in a respective groove 243" in the lower part of the housing.
  • the side bars shown in Figs. 9a to 9h, 10 , 11, 12d , 13a, 13b, 13c are very favorable in that the springs (e.g. 581 in Fig. 9d ), which push the side bar radially outwardly, are each located between a pair of side locking tumblers, so that the end of the side bar can be positioned very close to the front end of the key plug, thereby saving space.
  • the springs e.g. 581 in Fig. 9d
  • one of the springs should be positioned between the two neighboring side locking tumblers being located closest to the front end flange of the key plug and cooperate with the side bar.
  • the hole (e.g. 371c) for the side locking tumbler (e.g. 351c) being located closest to the front end of the key plug is located closer to the front end flange than all the central holes (e.g. 331a - 331g), whereby the space for the side locking mechanism is utilized efficiently, and there is consequently room for at least two and possibly three or four side locking tumblers in a row in the front region FR1, FR2, FR3 which is at the most half of the total length of the key plug and possibly much shorter.
  • the associated key 40 having a wave-like side code pattern 41 (see Fig. 2b ) with code portions interacting with the side locking tumblers, will have the entire side code pattern 41 located substantially within the half of the key blade being located closest to the grip portion of the key. Furthermore, the side code portion of this pattern 41 located closest to the grip portion will be located closer to the grip portion than all the V-shaped bittings 42 on the edge of the key, the latter bittings interacting with the central row of locking pins of the cylinder lock. In this way, these keys 40 will be distinguished from all prior art keys.
  • the key may alternatively have a wave-like side code pattern 41 on only one side of the key blade.
  • the other side may be just flat or provided with some other code pattern or configuration.
  • the side code pattern 141' on one side of the key blade is formed by two parallel upper and lower wall surfaces of a profile groove having a first part with two side code portions confined to the longitudinal half of the key blade, located closest to the grip portion of the key, and a second part forming a straight profile groove without any side code portions.
  • the other side of the key shown in fig. 14b , also has a first part with side code portions confined to the longitudinal half of the key blade located closest to the grip portion, and a second part forming a straight profile groove without any side code portions.
  • the profile groove is undercut and provided with a ridge portion where the side code portions are located.
  • the upper wall surface of the profile groove is straight all the way, so the side code tumblers of the lock unit interacting with the lower wave-like guiding surface of the profile groove must be biased downwardly, e.g. by springs, in order to follow the wave-like guiding surface.
  • the side code portions may be formed by concavities in the wave-like guiding surface of the undercut profile groove.
  • the V-shaped bittings of the upper edge code pattern may be sl ⁇ ew cut at different angles.
  • the wave-like side code pattern is selected from a group of possible code positions, the possible code position including, at different vertical levels:
