    A set of profile members in combination with a key plug, a method to manufacture such akey plug and a combination also including an associated key FIELD OF THE INVENTION The present invention relates generally to cylinder locks and more specifically to a set ofprofile members in combination with a rotatable cylindrical key plug having a longitudinalkeyway with a profile corresponding to an associated key. The invention also relates to amethod to manufacture such a key plug as well as a combination also including an associ-ated key. The profile members are accommodated in associated cavities in the key plug at one or both lateral sides of the keyway.
    BACKGROUND OF THE INVENTION AND PRIOR ART ln EP 0 634 542 A1(TrioVing AS) there is disclosed a prior art lock cylinder where the key-way has a set of profile members defining the cross-sectional profile of the keyway. Theseprofile members are constituted by rotation bodies inserted in cylindrical cavities beinglocated on each lateral side ofthe keyway. The profile members have a varying diameteralong a major portion of their length, so as to define a desired profile section in a planetransverse to the keyway. On the other hand, the cylindrical cavities, formed by bores, areuniformly wide along their length and must therefore have a diameter which can accom- modate the widest portion of the rotation body.
    Accordingly, the cylindrical cavities, housing the profile members, will occupy a substantialpart ofthe volume ofthe key plug on the lateral sides ofthe keyway. Therefore, there willbe a limited remaining space for accommodating bores where movable locking tumblersof the cylinder lock are to be disposed. This will cause a problem, especially but not onlywhen the key plug is provided with central locking tumblers, cooperating with a codededge portion of the key, as well as side locking tumblers, cooperating with a code pattern on a side surface ofthe key.
    Application text, 2015711706 090220SE OBJECT OF THE INVENTION Against this background, an object of the present invention is to provide a key plug wherethe set of profile members and their associated cavities will occupy a substantially smallervolume of the key plug, in the region located laterally adjacent to the keyway, so thatthere will be sufficient room for disposing further bores accommodating movable lockingtumblers. Moreover, it should be possible to manufacture a key plug with a specific profilesection in an easy and cost-effective way, offering a multitude of varying profile sectionswithout the use of complicated tools, while maintaining a limited volume for the cavitiesaccommodating the set of profile members. Also, it is an object of the invention to providea structure of an associated key which will permit a selective insertion of keys into thekeyway. Preferably, the structure should also make the key stronger, especially to with- stand substantial torsional forces.
    SUMMARY OF THE INVENTION These and other objects are achieved by providing a special structure with a set of profilemembers, each having a non-circular cross-section and being non-rotatably mounted inan associated cavity, each cavity being formed by a first part, located at a lateral distancefrom the keyway, and a second part, which communicates with said first part and is ex-tended laterally sideways so as to communicate with the keyway, said first and secondparts communicating via a narrowed part, and said profile members having first and sec-ond portions corresponding to said first and second parts of the associated cavity, a neckportion corresponding to said narrowed part and a cross-sectional contour being circum-scribed by the cross-section of said first and second parts of the associated cavity, so as tobe fitted in a non-rotatable well-defined position therein, said second portion of each pro-file member having a profiled surface portion facing inwards toward the opposite lateralside ofthe keyway, said profiled surface portion having, in a plane being transversal to a longitudinal axis of said key plug, a specific profile section defining a local, lateral part of Application text, 2015-11-06 090220SE said keyway, whereas said first portion and said neck portion of each profile member oc-cupy substantially the whole cross-section of said first part and said narrowed part of the associated cavity. ln this way, the first part of each cavity housing a profile member will be situated at somedistance from the keyway, and the diameter or widest portion of this part can occupy arelatively small volume. Consequently, the total volume of the cavities will be relativelysmall, and there will be sufficient space to accommodate further holes for housing a de- sired number of locking tumblers.
    The invention also provides a method of manufacturing a cylindrical key plug having a pro- filed longitudinal keyway adapted to cooperate with an associated key, wherein - the key plug is machined to form a longitudinal slot with a uniform cross-sectionalprofile, - a number of cavities are made in the key plug on at least one lateral side of the longi-tudinal slot, each cavity being formed by a first part, located at a lateral distancefrom the keyway, and a second part, which communicates with said first part and isextended laterally side-ways so as to communicate with the keyway, said first andsecond parts communicating via a narrowed part, - a set of profile members are inserted into said cavities, - each profile member having a non-circular cross-section, including a first portion cor-responding to said first part ofthe cavity, a second portion corresponding to said sec-ond part of the cavity, and a neck portion corresponding to said narrowed part of thecavity, said non-circular cross-section of each profile member being circumscribed bythe cross-section of an associated cavity, and - each of said profile members being non-rotatably mounted in a respective cavity at alocation adjacent to said key slot so as to form a lateral part thereof, with a profiledsurface portion on said second portion ofthe profile member facing inwards towardthe opposite lateral side of the key slot, said profiled surface portion having, in aplane being transversal to a longitudinal axis of said key plug, a specific profile sec- tion defining a local, lateral part of said profiled longitudinal keyway.
    Application text, 2015-11-06 090220SE Preferably, the cavities are formed by making two adjacent and partially overlapping par- allel bores, which constitute said first and second parts of the cavity.
    The profile members, or at least one or two of them, may be made of hard material whichis substantially harder than the material of the cylindrical key plug. lt is per se previouslyknown to provide side members or ”locking bolts” of a hard material so as to provide anti-drilling protection, e.g. as disclosed in figs. 15 - 31 and the associated part ofthe descrip-tion of EP l 466 039 A” (Talleres De Escoriaza S.A.). ln this prior art embodiment, however,the oppositely disposed ”locking bolts” are located entirely in associated cavities at somedistance from the wall material defining the keyway, and these locking bolts do not form apart of the wall surface defining the keyway. So, the profile section of the keyway is pro-duced in an ordinary way, with special tools that can cut out the particular profile section of the keyway.
    According to another aspect of the invention, the profile member/key plug combinationalso includes an associated profiled key having a profile section corresponding to the spe- cific profile section of the keyway of the key plug.
    BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained further with reference to the appended drawings il- lustrating a preferred embodiment of the invention.

    DETAILED DESCRIPTION OF SOl/IE PREFERRED El/lBODll/IENTS OF THE INVENTION ln fig. 1a there is shown a key 10 and cylinder lock having a stationary housing 20 and a ro-tatable cylindrical key plug 30. As is well-known in the art of cylinder locks, the key plug 30can be rotated, normally by means ofthe key 10, when a number of locking tumblers (notshown) in the key plug are positioned so as to leave a shear line free between an outersurface ofthe key plug 30 and an inner surface ofthe housing 20.|nfig.1c one can see anumber of bores for accommodating such locking tumblers or pins, in this case a row ofcentral bores 31 accommodating central pins (not shown) and another row of bores 32 for side locking tumblers (not shown either). ln addition to the bores 31, 32, there are a number of bores 33a, 33b, 33c, 34, being paral-lel to the bores 31,32 and being shown better in fig. 1b with dashed lines. These bores33a, 33b, 33c, 34 or cavities serve to accommodate a set of profile members 43a, 43b,43c, 44 which are non-rotatably mounted in the respective cavities 33a, 33b, 33c, 34, re- spectively. See fig. 2a.
    Actually, each cavity 33a, 33b, 33c, 34 is constituted, in the preferred embodiment shownon the drawings, by two adjacent and partially overlapping parallel cylindrical bores, hav-ing a contour like the digit ”8”. This will be seen in fig. 1d, illustrating two opposite cavities each housing a profile member (not shown).
    According to the present invention, each of the profile members 43a, 43b, 43c, 44 has anon-circular cross-section and is non-rotatably mounted in an associated cavity 33a, 33b,33c, 34 at a location adjacent to the keyway 39 (see figs. 1c, 1d, 1e). The arrangement is such that the cross-sectional size of these cavities is relatively small and makes it possible Application text, 2015-11-06 090220SE to leave enough room in the key plug for accommodating the further rows of bores 31 and 32.
    As will be seen from fig. 1d, each cavity is formed by a first part 100, located at a lateraldistance from the keyway 39. ln this embodiment this part 100 is a cylindrical bore with acircular cross-section. The first part 100 is extended sideways into a second part 101,which communicates with the first part 100. The second part 101 also communicates di-rectly with the keyway 39. ln this embodiment, the second part 101 is also formed by a cy- lindrical bore, which partially overlaps with the bore forming the first part 100.The first and second parts 100,101 communicate with each other via a narrowed part 102.
    The associated profile member 44 is configured to fit, with a slight play, into the cavity100,101 and has a first portion 200 corresponding to the first part 100 of the cavity, a sec-ond portion 201 corresponding to the second part 101 ofthe cavity, and a neck portion202 corresponding to the narrowed part 101 of the cavity. The cross-sectional contour ofthe profile member is circumscribed by the cross-section of the first and second parts100,101 of the cavity. Also, at least the first portion 200 and the neck portion 202 oftheprofile member occupies substantially the whole cross-section of the first part 100 and thenarrowed part 102 ofthe cavity. ln this way, the profile member will be fitted non-rotata-bly in a well-defined position in the cavity 100,101. Thus, the profile member cannot ro-tate or turn, but it may be movable elevationally in the cavity, if so desired. lt should bepointed out that the first and second parts of the cavity, and the first and second portionsof the profile member, do not have to be part-circular in cross-section but may have a dif-ferent geometrical configuration, e.g. more elongated or rectangular. Also, the overallshape should be such as to prevent that the profile member falls out from the cavity into the keyway. ln accordance with the invention, a main function ofthe profile members 43a, 43b, 43c,44 is to provide a profile section of the keyway, by forming a part of the lateral side of thekeyway. For this purpose, the second portion 201 ofthe profile member is provided with a profiled surface portion 201a (see fig. 1e) facing inwards toward the opposite lateral side Application text, 2015-11-06 090220SE of the keyway. This surface portion can be varied so as to provide a specific profile sectiondefining a local, lateral part of the keyway. See the various profile members shown in figs. 8a, 9a,..., 17a. ln a preferred embodiment, as illustrated on the drawings, the surface portion 201a isconvex and arcuate in cross-section, so that, in a plane which is transverse to a longitudi-nal direction of the keyway, the surface portion 201a has a specific profile which will becomplementary to the profiled key 10 and will guide the latter when it is inserted longitu-dinally into the keyway. There are preferably such profile guiding surface portions on bothlateral sides of the keyway, so that the key is guided precisely between these lateral pro-filed surfaces. lt will be understood that the keyway is not uniform all the way in the longi-tudinal direction but has a number of profiled lateral sections that will ensure a properguiding and screening. Only keys having a profile that corresponds to the various profiledlateral sections of the profile members will fit into the keyway. This is illustrated also byfig. 3 which shows how the key 10 fits precisely between the profile members 43c and 44.The other profile members 43a and 43b are hidden behind the profile member 43c, ex- cept for a small lug projecting into the keyway.
    The profile members may be arranged in a many different ways along the keyway, as ex-emplified by fig. 2a, where there are three profile members 43a, 43b, 43c on one side ofthe keyway and one profile member 44 on the other side, fig. 4a, where there are onlytwo profile members 45a, 45b on one side of the keyway, fig. 4b, where there are twoprofile members 45a, 45b and 46a, 46b on each side ofthe keyway and the pairs beingdisplaced longitudinal relative to each other, and fig. 4c, where there are three profilemembers 47a, 47b, 47c and 48a, 48b, 48c, respectively, on each lateral side of the keywayand the profile members being located opposite to each other pairwise (47a, 48a and 47b,48b and 47c,48c). lt will be understood that there is a great flexibility in respect of the par-ticular arrangement ofthe set of profile elements. lt will be possible to locate the profilemembers in positions that are suitable in view of the locations of other bores in the key plug (compare fig. 1c).
    Application text, 2015-11-06 090220SE ln the particular embodiment of the key shown in fig. 4b, the groove in the side surface ofthe key is relatively short. ln general, the grooves in the side surface ofthe key may havedifferent lengths so as be no longer than to match the position of the profile member hav-ing a lug or other profile part that projects into the groove when the key is fully inserted into the keyway.
    By providing side grooves of different lengths, it will also be possible to make a lock andkey system to become selective. Thus, a key as shown in fig. 4b will fit into a key plug withprofile elements as shown in fig. 4a, but not in a key plug with profile members as shownin fig. 4c, whereas the key of fig. 4c will fit into the key plug with profile members as shown in figs. 4a and 4b.
    An embodiment, where the groove or grooves are relatively short, will have the advantageof making the key stronger in the portion closest to the grip. ln this way, the key will with-stand strong torques when the key is turned in order to rotate the key plug. Of course, if the key has a solid material in its cross-section, the torque resistance will be stronger.
    Normally, the surface portion 201a on the profile members faces the opposite side of thekeyway at right angle. However, as shown in figs. 5,5a and 5b, it may be advantageous tolet the cavity and the profile surface of the profile member face or point in a directionwhich is oblique to a transversal plane to the keyway. ln fig. 5a, the second portion 201 ofthe profile member 46'a is pointing at an angle ot towards the tip end of the key, whereasthe oppositely located profile member 45'a stands at right angle to the keyway and thekey. ln fig. 5b, on the other hand, the second portion 201 ofthe profile member 46'bstands at an angle ß in a direction towards the grip end ofthe key. Here, the opposite pro- file member 45'b stands at right angle to the key 10. lt may be favorable to have a pair of profile members , such as the profile members 47aand 48a, in the vicinity of an entrance opening of the keyway (to the left in figs. la and fig.lb), with the second portions 201 of these profile members both pointing at an angle to-wards the grip end of the key 10. Then, one can make effective use of the available space in the keyway. Compare fig.1c and fig. 2a, also showing a pair of profile members 43a, 44 Application text, 2015-11-06 090220SE in the vicinity ofthe entrance opening ofthe keyway. With such an arrangement, there will be much room for other bores 31, 32 (fig. 1c) in the key plug. ln embodiments having profile members arranged adjacent to the entrance opening ofthe keyway, such as in fig. 2a and fig. 4c, it may be favorable to make the profile membersof a very hard material to provide drill protection and prevent the lock to be destroyed (ormaking it more difficult to destroy the lock). Thus, the profile members, even those lo-cated at other positions along the key plug, may be made of hardened steel, e.g. case hardened steel, or tungsten carbide. The rest ofthe key plug is normally made of brass.
    The concept of providing a complex profile configuration ofthe keyway by means of theprofile elements is well illustrated in figs. 6, 7 and 7a. First, a relatively simple geometricalconfiguration of a key slot is machined in the key plug, as shown in fig. 6 (without any pro-file members). This configuration may e.g. consist of two rectangular (in cross-section per-pendicularly to a longitudinal axis of the keyway) parts, viz. an upper rather narrow rec-tangular part 1 and a lower, somewhat wider rectangular part 2. Such parts are relativelyeasy to manufacture, e.g. by means of a cutter disc, or even a cutter pin being guided lon- gitudinally along the key plug.
    Then, the desired profile of the keyway is obtained by inserting profile members as de-scribed above. Fig. 7 shows the resulting keyway having, in addition to the basic rectangu-lar configuration, a number of irregularities formed by lugs 3, 4, 5. Of course, by varyingthe surface portions 201a on the profile members, it is possible to achieve a desired pro-file section, even with a complex or special configuration. ln this way, it will be possible toprovide a multitude of profile variations by simply exchanging the particular profile mem- bers.
    The profile members may be configured or tailor-made in many different ways. As men-tioned above, the first and second portions 200 and 201 (fig. le) may be non-circular in cross-section, although it is very convenient and cost-effective to make these portions Application text, 2015-11-06 090220SE 11 part-cylindrical, with a part-cylindrical cross-section. The associated cavities are also rela-tively easy to manufacture, e.g. by drilling bores that partially overlap each other, as illus- trated in fig. 1d. ln figs. 8a, 8b, 8c; 9a, 9b, 9c; etc. a number of possible embodiments ofthe profile mem- bers are illustrated. ln figs. 8a, 8b, 8c, the profile member 141 is provided with an upper straight portion 141awhich protrudes sideways into the keyway, compare fig. 3, and two lower lugs 3,4 whichwill form a part of the lateral profile ofthe keyway. Such lugs are also visible in fig. 3. Thesecond portion 201 ofthe profile member 141, see fig. 8c, is widened and has a slightly convex surface portion defining the profile. ln figs. 9a, 9b, 9c, the profile member 142 is quite similar, with an upper straight portionand two lower lugs, but has an even wider second portion 201. ln this case, the surface portion defining the profile is flat.
    The embodiment of the profile element 143 shown in figs. 10a, 10b, 10c has a straight sur-face portion 201 extending all along the profile member, and two lower lugs 3, 4 project-ing into the keyway. These lugs 3,4 are shaped very much like the lugs 3,4 in figs. 8a, 8b, 8c, with a slightly convex surface portion defining the profile ofthe lugs..
    The profile member 144 shown in figs. 11a, 11b and 11c is similar to the embodiment offigs. 10a, 10b, 10c, but has only one lug 5, which projects a little longer into the keyway.
    The surface portion defining the profile is slightly convex. |nfigs.12a, 12b, 12c, the single lug 5 of the profile element 145 is much wider than in the preceding embodiment and also has a convex surface defining the profile.
    The embodiment shown in figs. 13a, 13b, 13c is quite similar to that shown in figs. 12a,12b,12c but its single lug 5 is located lower, not far from the lower end ofthe profile ele- ment 146.
    Application text, 2015-11-06 090220SE 12 |nfig.14a, 14b,14c, the profile element 148 has two lugs 3,4 and also an upper annular re-cess 6 which will accommodate a longitudinal rib portion (not shown) on an associated key (not shown either).
    The embodiment shown in figs. 15a, 15b, 15c is similar, with an upper recess 6, but theprofile element 148 has only one lug 5. The second portion 201 (fig. 15c) is rather wide, and the surface portion defining the profile is flat. ln figs. 16a, 16b, 16c, there is shown a profile element 149 having a single lug 5 with atongue portion 5a and a downwardly pointing end portion 5b. Such a lug 5, with a down-wardly (and/or upwardly) pointing end portion can be accommodated in an undercutgroove in a side surface of an associated key (not shown). Such a groove may have one or two (upper and lower) undercut portions. |nfigs.17a and 17b, there is shown a key 10 similar to the one shown in fig.2a. However,in this embodiment, there is no stop shoulder near the gripping portion, as is a conven-tional structure of a cylinder lock key. lnstead, one of the longitudinal grooves 11, 12 in aside surface ofthe key is shorter (the groove 12) and has at its end a stop surface 12a, which will replace the conventional stop shoulder near the grip ofthe key.
    The profile elements, the key plug and the associated key according to the invention maybe modified in relation to the preferred embodiments described above. As indicatedabove, the cross-section of the two portions 200, 201(fig. 1e) ofthe profile element maybe non-circular, and the neck portion may be almost negligible, so that the overall cross-sectional shape is almost oval or elliptic. However, the configuration must be such that the profile member does not fall out of the associated cavity.
    The exact cross-sectional shape ofthe profile element does not have to correspond ex-actly to the surrounding cavity. However, in order to utilize the available space in the keyplug, the material of the profile element should substantially fill out the volume of the first part 100 of the associated cavity (see figs. 1d and 1e).
    Application text, 2015711706 090220SE 13 Of course, the key plug may have only one kind of locking tumblers or pins, e.g. only pinscooperating with an edge portion of the key (and no side tumblers), or other kind of tum- blers, such as side tumblers being movable at right angle to a side surface ofthe key.
    The profile configuration of the keyway, and of the associated key, may be varied widely,with more grooves on the side surfaces of the key, or a number of stepwise transitions ofthe profile. With the profile being determined by the exchangeable profile members, it isrelatively ease to obtain a desired profile section, even with a rather complicated geome- try.
    The key should be substantially flat, possibly with differently thick upper, middle and lower portions.
