The inside diameter of the ring, is greater than as outside dtatneier of the shaft, The shaft, winch may also be railed a pit', or ixth, need not necessarily be rtthtttonally sysnntetriettl. For esample, an enter periphery or tin; shaft sway have a circular cross-section, For example, an order periphery of the shaft may also have .an elhpitetd cross-section, The iertn "outside diameter” therefore fk\»h\'k' ! u etc 4>’t\ ' ni h< ,<k', ,u ' y \ > die dtdt * tntv wo ds ft«, ' ft ,u\ u >d ,'t, otde.f circle around the outer periphery of the shaft, IT the outer eireuiufereoimt contour of the shaft is fottned circulas. s.»e outside diathOfor is constant? and cos.sequetttly eosrespcsrt.ds to tire largest outside diameter of the shaft. Accordingly, the ring can rotate about the shaft and is mounted on the shaft wnh a play which also allows a translational movement of the ring relative to the shaft. |δδ13| At least two rings are ttrrattged on the shaft next to each other, In particular, the rings are arranged directly next to each other. The phrase "next to each other” here means that tit« rings are arranged adjacent to each other, ht particular directly adjacent. There are therefore no sleeve elements, spacers or other «dements between the rings. The rings may in particular lie against each other, it Is evident that a degree of play is maintained in order to alldw the rotation of the nogs relative to each other or a. twtshd.iöoal movemetft of the tin’s 11» s< <-, kh 'tin, 5 t It t' t>„>t e <>i i„tme >\ to < <k t othu o > tlu i »>m non '' tl In k embodiment according to she invention, the rings can rotate on she shaft ittdepsndcndy of each ether.

This is achieved since their inside diameter is larger than the ontstde diameter of the shaft. The exteift by which a ring can. be moved perpendicularly to She longitudinal axis of the. shaft is therefore measured by bow much greater the inside diameter of the ring is than She outside diameter of the shaft, lit particular, the inside diameter of the ring may amount so ! ,25 times the outside diameter of the shaft, in parfsoulsr to 1,5 times, in particular 2 times, further partietslarly 2.5 times.

[0023] According. to- the Inventftm, the rings are formed eyunneftieally .relative- io a rotational symmetry axis, and asymmetrically relative to a ring centre plane running perpendicularly io the rotationai symmetry axis. In particular, an outer circumferential face of the rutgmay be formed asymmetrically to-the ring centre plane.

[0024] The asymmetric configuration may for example allow the ring cross-section to be used as an additional sensing means, for example, such an asymmetric rmg cross-section, in particular the outer circumferential face, mtty correspond to a corresponding recess in a key elinnnek .so that curly oorrpspopdipgly configured asymmetric rings allow tbc insertion of the key in the key channel, [0026] In a forther embodiment of the key, ft-may be provided that the cutout. is arranged symmeb rioaliy to a <emtv phnw ofthc kev su,rd. that extends perpewficvkn ρ re foe key broad aids faces and parallel to a centre pl.mv »f the tes shank Pan cstvnd, m the tovg-mdinsi «ImMten [0026] The key shank has the η·η{η<ΡΙ\ oppvMfte kes busk! side face» and tue also mutually opposing kev nmow f.idi? faces winch co-u.eu the kc\ l«oud side fisee>. the key shank is substantially rectangular in cross-sea,on. fhc two longet srdu w»'thc re< tonale are the few bruad side faces", "fite two short sides are the ’’key -»sîtow ekle .feces'’.

As a result, ihe rings are arranged perpendicularly to the key broad side faces. This faciiitates a syrntnefftcal arrangement of the rings relative to a centre plane of the key shank and provision as a seversibte key.

[0838] In a lurihet embodiment offne Rev, it may be provided thai the key shank iras at least one longitudinal groove in nt least one of the key broad side faces, said longitudinal groove extending patailel to da; longiftidsnai direction, [8848] In principle. naturally a long! tud Inal groove tnay be provided in each, of the broad side faces V \ vs p«,f\t <?>'to >\ impie r< te w, > mmshk \e<. 1ft m,m o to ciyJn t go >os < u w\ sectional profile of the key bit can be set and farther sensing enabled, for example by corresponding configuration of a cross-sectional profile of a key eltannei in a cylinder core of the lock cylinder, [8841] in a farther embodiment of the key. ft tnay be provided that die key shank has, in at (east one of the key broad side faces, at least one depression to be sensed by a profiled pin.

[0842] ftt this way, by means of tbc depression, a farther security feature can be implemented in the key in order to further increase the security' of the key.
