Definitions

  • the invention relates to a profile locking cylinder with a cylinder housing and a cylinder core rotatably mounted therein, which can be blocked by key-operated pin tumblers arranged at the same distance from one another and which is secured against axial displacement in the cylinder housing by a locking ring arranged in the key area between the core and the cylinder housing.
  • Profile lock cylinders of the above type are known for example from DE-B-11 44 615 or DE-B-25 33 494.
  • the thereby securing the core against axial displacement of the core relative to the cylinder housing when the core is not blocked by the pin tumblers is located between the cam and the inner end face of the cylinder housing and projects with its inner circumference into an annular groove located at the inner end of the cylinder core. Since this securing ring, which is usually designed as a simple snap or spring ring, engages the inner end of the cylinder core, which is already weakened by the engagement with the lock-type coupling, it, like the tumbler pins in the blocking position, only represents an inadequate axial securing of the cylinder core.
  • the invention has for its object to provide a profile lock cylinder of the type mentioned, which has an even greater security against unauthorized axial pulling out of the cylinder core without extending its axial length, but still allows an authorized non-destructive removal of the cylinder core, and with double profile cylinders also requires no separation or releasable connection of the two housing halves.
  • a profile lock cylinder of the generic type according to the invention in that, as an additional axial core lock in the area of the pin tumblers, while leaving their equally short distances on the cylinder core, a locking washer which extends transversely to its longitudinal axis and protrudes over its circumference in an arc-proof manner is attached in a rotationally secure manner, the axially securing part protrudes over a large area into a core cut provided in the cylinder core and the other part, at least when the key is removed, into a housing cut located at the same height in the cylinder housing.
  • the housing incision can advantageously be designed as a continuous separating cut surrounding the cylinder core and the locking washer projecting into it as the cylinder core in its cross-sectional area narrowed by the core incision, largely encompassing one-sided open, radially resilient washer.
  • the separating cut to be made in the pin tumbler area weakens the cylinder housing at this point, but is not harmful with regard to the intended axial securing of the core, in particular not if this separating cut is made in the middle area of the pin tumblers.
  • the remaining parts of the cylinder housing are still sufficiently strong and, moreover, the extractor to be used in the event of unauthorized use is placed on the front edge of the cylinder housing surrounding the core and is thereby supported when pulling.
  • the core incision can also be designed in the form of a segment of a circle and the locking washer can be designed as a correspondingly contoured segment disc which fits fully into it, and which, with its circular arc-shaped outer circumference, has a spring arranged between it and the core in the key withdrawal position of the core in a correspondingly crescent-shaped profile, the housing incision forming internal recess in the housing.
  • the invention further provides that in addition to the faceplate screw bore, at least one further continuous transverse bore and a security bolt to be inserted into it, which protrudes on both sides beyond the profile of the locking cylinder, are provided in the housing web are.
  • the double-profile locking cylinder shown in Fig.1 is conventionally provided with two cylinder housing halves 1, 1 ', which in the area of the locking bar 3 located between them in a corresponding recess 2 via the housing web 1 ⁇ with the cuff screw bore 4 usually present therein, firmly connected to one another Are texture.
  • the cylinder cores 5.5' are rotatably mounted and blocked by the pin tumbler elements 6 accommodated both in them and in the housing web parts.
  • the tumbler pins By inserting the appropriate key into the key channel 5 ⁇ in the cylinder core, the tumbler pins can be moved against their spring action into their open position, in which the core 5 or 5 'can be rotated relative to the cylinder housing part 1 or 1' by means of the inserted key, whereby the lock bit 3 performs a corresponding rotation and actuates the lock, not shown, in the opening direction.
  • the double profile cylinder shown has two transverse bores 7 in the region of its housing web 1 ⁇ .
  • a bore 7 is in the bore 7 facing the outside of the door Securing bolt 7 'protruding from the profile of the cylinder on both sides is inserted, which in the installed state reaches behind the lock case base or the lock case cover and thereby unauthorized pulling out or also driving the entire lock cylinder out of the lock case or even breaking off the cylinder in the amount of its lockable recess 2 and the faceplate hole 4 weakened web area prevented.
  • a locking washer 9 extends transversely to its longitudinal axis and protrudes arcuately over its circumference on the outer cylinder core 5 attached against rotation. This protrudes over a wide area, axially securing, partly into a core cut provided in the cylinder core 5 and partly, at least when the key is removed, into a housing cut 8 located in the cylinder housing 1 at the same height.
  • the housing cut 8 can be designed as a continuous separating cut surrounding the cylinder core 5 all around, while the locking washer 9 protruding therein as the cylinder core 5 in its cross-sectional area narrowed by the core cut largely encompasses one-sided open, radially resilient Washer is formed.
  • the core incision 10 consists of two incision segments 10 'present on both sides of the key channel 5 ′′ located in the core 5, while the locking washer 9 is designed here as a ring fork, namely has the shape shown in Figure 3.
  • This ring fork 9 passes through with its segment-shaped fork legs 9 ', the incision segments 10' in the core 5, while the fork web 9 ⁇ encompasses the cylinder core 5 on its side opposite the key channel 5 ⁇ , as shown in particular in FIG.
  • This also shows that in order to push the ring disk 9 onto the core 5, the latter must be in a rotational position offset by 180 ° with respect to FIG.
  • the cylinder core 5 has an axially parallel locking bar 13, which can be brought into engagement with an axially parallel inner circumferential recess 1 ′′′ in the cylinder housing, and radially displaceable and blockable control levers 14, the tilting on a common axis bolt 15 running parallel to the key shaft 5 lag and to be acted upon by incisions on the side of the key.
  • the locking bar 13 here forms an additional anti-rotation device for the core 5, that is to say in addition to the pin tumblers 6 which are also present throughout.
  • the core 5 is provided with an eccentric, crescent-shaped annular groove 11, in which spring washers 16 and 17, respectively, designed as a lock washer, which protrude into the recess 8 in the housing and are fixed against rotation.
  • spring washers 16 and 17 respectively, designed as a lock washer, which protrude into the recess 8 in the housing and are fixed against rotation.
  • the spring ring 16 In the case of Figure 4 is the spring ring 16 almost closed all around and provided at the level of the locking bar 13 and the key channel 5 ⁇ inner recesses 16 'and 16 ⁇ .
  • the locking ring 17 extends over about two thirds of the core circumference, wherein it in turn has an inner recess 17 'located at the level of the locking bar 13' and leaves the key channel 5 ⁇ completely uncovered.
  • the core incision consists of a on the control levers 14 opposite side of the core 5 situated incision segment 5 IV, in which the locking washer 18 has a U-profile, the web portion is formed as a segment 18 'and located in the core recess segment 5 IV, while the legs of the U as a ring-shaped spring leg 18 ⁇ , 18 ′′′ partially encompass the core 5.
  • the core 5 has an incision 19 in the form of a segment of a circle, while the locking washer is designed as a correspondingly contoured segmented disk 20 which fits fully therein. Between the latter and the core 5, a compression spring 21 is arranged, which tries to move the segment disc 20 radially outwards. In the key withdrawal position of the core 5 shown in FIG. 7, this is possible because the disk 20 with its circular arc-shaped outer circumference is then to be pressed into the correspondingly crescent-shaped housing recess 22 which here forms the housing incision. This also creates an additional axial securing of the core 5.
  • the locking washer 20 is pressed completely into the circular segment-shaped incision 19 of the core.
  • the core 5 can be easily removed after prying off the externally accessible locking ring 5a located in the lock bit area, that is to say it can be pulled axially out of the housing 1 by approximately Lock changes or the like on the tumbler pins. to be able to make.
  • the safety washer 20, for example made of sintered stainless steel advantageously has the cross section shown in FIGS. 8 and 9, with its axially wider peripheral part 20 ', on which the projecting locking edge 20' is located, in the correspondingly wider crescent-shaped inner recess 22 of the housing 1 protrudes.
  • the securing segment disk 20 is tilted accordingly when the core 5 is pulled out, its locking edge 20k reliably preventing the segment disk 20 from sliding radially into the core incision 19.
