Abstract

The invention relates to a lock cylinder (1) with the cylinder housing (2) and a cylinder core (4). Rotation of the core can be blocked by an arresting element (7) which can be actuated by electrical energy. The arresting element (7) can be laterally displaced within its clearance (8) and, in the state in which the core is blocked, is supported on a shoulder (10). <IMAGE>

Description

10 15 20 25 30 506 776 2 8 och 22, beﬁnner sig spärrelementet 7. Urtaget 8 har i bottenområdet en avsats 10. I ett ytterligare urtag 11 i cylinderhuset 2 är anordnat en elektromagnet 12, och mellan denna och spärrelementet 7 beﬁnner sig en bladtjäder 14. Under verkan av denna bladtjäder trycks då, när elektromagneten är strömlös, spärrelementet i riktning mot tillhållarelementet". I detta läge är spärrelementet fritt förskj utbart i urtaget, dvs. vid en vridning av cylinderkärnan 4 skulle det genom urtagets 9 lutande ytor 21 i cylinderkäman förﬂyttas ungefär vertikalt nedåt mot trycket av ﬁädem 20, varmed det bringas utom ingrepp med cylinderkäman, så att denna kan vridas ytterligare. 10 15 20 25 30 506 776 2 8 and 22, the locking element 7 is recessed. The recess 8 has a ledge in the bottom area 10. In a further recess 11 in the cylinder housing 2 is arranged an electromagnet 12, and between this and the locking element 7 forms a leaf cape 14. Under the action of this leaf cape it is then pressed, when the electromagnet is de-energized, the locking element in the direction of the tumbler element ". In this position is the locking element freely displaceable in the recess, ie. upon a rotation of the cylinder core 4 would through the sloping surfaces 21 of the recess 9 in the cylinder core for ﬂ is moved approximately vertically downwards towards the pressure of ﬁ edema 20, thereby bringing it out of engagement with the cylinder core so that it can turned further.

Om nu en nyckel 5 införs i cylinderkäman, förﬂyttas på känt sätt tillhållama 16 nedåt, varvid ett av dessa tillhållarelement, såsom visas på ritningen, är försett med ett urtag.If a key 5 is now inserted into the cylinder core, the holders 16 are moved in a known manner downwards, one of these tumbler elements, as shown in the drawing, being provided with a recess.

Detta är betecknat med 19.This is denoted by 19.

I cylinderhusets mellanvägg, mellan tillhållarborrningen och spärrelementet är anordnad en borrning 18 och i denna beﬁnner sig en kula 15. Om nu tillhållarelementet 6 och därmed elementet 6' rör sig nedåt, trycks kulan åt höger på ritningen och verkar därmed på spärrelementet 7, så att detta förflyttas väsentligen vinkelrätt i sidled i ritning mot elektromagneten, närmare bestämt mot ﬁäderns 14 kraft.In the partition wall of the cylinder housing, between the tumbler bore and the locking element is arranged a bore 18 and in this a ball 15 settles. If now the tumbler element 6 and thus the element 6 'moves downwards, the ball is pushed to the right in the drawing and thus acts on the locking element 7, so that it is moved substantially perpendicularly laterally in the drawing towards the electromagnet, more specifically against the force of the ﬁ 14.

Spärrelementets längd är nu dimensionerad på sådant sätt, att det beﬁnner sig i ingrepp med uttaget 9 i cylinderkäman när det anligger på avsatsen 10, dvs. där är understött. I detta läge år ej längre möjlig någon rotationsrörelse eller vridning av cylinderkäman, och som framgår av det föregående uppnås detta tillstånd redan vid inskjutningen av nyckeln.The length of the blocking element is now dimensioned in such a way that it settles in engagement with the socket 9 in the cylinder core when it rests on the ledge 10, i.e. there is supported. In this position, no rotational movement or rotation is possible cylinder core, and as shown above, this condition is already achieved at the insertion of the key.

Vid dessa samverkande rörelser kan kulan 15 inträda i urtaget 19.. Under detta förlopp har även elektromagneten aktiverats och håller spärrelementet draget. Om nu berättigandet tillbakavisas, blir elektromagneten strömlös, så att under verkan av tjädem 14 kan ske en förflyttning eller omlagring av spärrelementet 7 utan hinder av kulan 15 i riktning mot tillhållarelementen. Därmed uppnås det läge som därefter tillåter en tillbakaskjutning av spärrelementet vid cylinderkärnas vridning.During these cooperating movements, the ball 15 can enter the recess 19 .. During this process, the electromagnet has also been activated and keeps the locking element pulled. About now the entitlement is rejected, the electromagnet becomes de-energized, so that under the action of the tether 14 a blocking or rearrangement of the blocking element 7 can take place without obstruction of the ball 15 in direction against the tumbler elements. This achieves the position which then allows a bounce of the locking element when the cylinder cores rotate.

Efter avslutning av låsförloppet förflyttas tillhållarelementet 6' uppåt under verkan av ﬁädern, så att åter kan uppnås det läge som visas i tig. 1. ._ I Det andra utförandet är, såsom visat i ﬁg. 2, principiellt lika i konstruktion, dvs. även i detta fall har spärrelementet 7 sådan längd, att det hindrar vridning av cylinderkäman 4 när det sitter på avsatsen 10.After completion of the locking process, the tumbler element 6 'is moved upwards during action of the ﬁ, so that the position shown in fig. 1. ._ In The second embodiment is, as shown in ﬁ g. 2, in principle the same in construction, ie. also in this case the locking element 7 has such a length that it prevents rotation of the cylinder core 4 when sitting on the ledge 10.

I motsats till den mekaniska utlösningen av spärrverkan är dock härvid anordnat så att medelst ett endast antytt sensorelement 24 nyckelns inskjutning registreras, varvid 5 O 6 7 7 6 3 _ magneten 12 genast aktiveras och draget spärrelementet 7, dvs. omlagrar det väsentligen vinkelrätt till urtagets tillhållarelement, så att det kan anligga på avsatsen 10.In contrast to the mechanical triggering of the blocking action, however, it is so arranged that by inserting only the indicated sensor element 24 the insertion of the key is registered, wherein 5 O 6 7 7 6 3 _ the magnet 12 is immediately activated and the locking element 7 is pulled, i.e. essentially rearranges it perpendicular to the bracket element of the recess, so that it can abut on the ledge 10.

Om berâttigandet tillbakavisas, blir magneten 12 strömlös och ijädern 14, vilken befinner sig mellan magneten och spärrelementet, trycker detta spärrelement åter i riktning mot tillhâllarna, så att därvid är möjlig en förskjutning mot tjäderns 20 kraft vid rotation av cylinderkåman.If the justification is denied, the magnet 12 becomes de-energized and the spring 14, which is located between the magnet and the locking element, this locking element pushes again in the direction against the tumblers, so that a displacement against the force of the capercaillie 20 is possible upon rotation of the cylinder head.
