Definitions

  • the invention relates to a locking cylinder, whose core rotatable in the housing radially to one Key channel has adjacent sliding core pins that with spring-loaded housing pins when actuated with a key cut in the sense of a Release a rotational movement of the core cooperate, and which has at least one further blocking part in its core, that with the key tip of the key in it Direction of insertion against a spring force from a locked position with radial locking engagement in a rotational release position is adjustable, in which the housing has an annular groove, that freedom of movement for the rotating locking part is located outside a region of the core pins is, the locking part is a limited longitudinally adjustable in the core Sliding block with a radially projecting and in a longitudinal recess of the housing in the direction of key insertion movable grooved pin.
  • a lock cylinder with the features mentioned above is known from DE-C-10 55 996.
  • the invention has for its object a locking cylinder to improve with the features mentioned at the beginning, that he has greater security against the use of offers wrong keys without sacrificing functional reliability of conventional pin tumblers.
  • a radial The locking part engages in the housing in order to exclude unwanted rotational movement of the core that on the other hand but an axial one, i.e. in the direction of insertion Adjustment movement of the locking part is necessary to this to move to the rotational release position.
  • the locking part of a conventional design of a lock cylinder can be optimally adjusted without or having to intervene in the key channel area.
  • the locking cylinder is designed so that the locking part a slot nut that is limited in its length a radially projecting and in a longitudinal recess of the Groove pin movable housing in key insertion direction is.
  • the longitudinally adjustable sliding block ensures that the in the Longitudinal recess movable grooved pin from its locked positions to move into the only permissible rotation release position is when the approved key is in the key channel is inserted.
  • the sliding block can be used together with the grooved pin are designed as a solid unit that all requirements are sufficient to avoid violent twisting to prevent the core when the sliding block is in a Locked position.
  • a particularly cross-sectional design of the locking part and thus training the lock cylinder accordingly increased level of security and reliability is achieved when the locking part next to the key channel is arranged and has an adjusting pin which in the key channel through one of the movements of the locking part allowing longitudinal slot engages.
  • the adjustment pin requires that the in the key channel introduced key its interpretation or arrangement on the sliding block is designed accordingly, thus the locking part in the intended rotation release position is adjustable.
  • the dimensioning of the adjustment pin and its arrangement form from lock cylinder to lock cylinder variable security parameters.
  • the longitudinal recess of the housing as a grooved pin Breakthrough is formed through which the grooved pin with Locking part is assembled after that with the locking part provided core is built into the housing.
  • the longitudinal recess of the housing it is possible to use the longitudinal recess of the housing not to the end or to recess on the lockable side. Much more is an arrangement of a longitudinal recess only in the displacement area of the blocking part required. Because the longitudinal recess or the breakthrough is formed slot-wide is, the slot pin fits through and can after assembly of the core can be used with the housing, however the blocking part does not fall out of the opening.
  • the longitudinal recess of the housing extends beyond the annular groove. An inappropriate one The key pushes the locking part over the rotational release position out, so that a lock is achieved, similar like with the tumblers. A twisting of the key in the release position is not possible because the core pins are not improperly adjusted by the key and prevent core rotation.
  • the above task is for a lock cylinder solved with the features mentioned above in that the limited longitudinally adjustable locking part in the locking position next to the core pins and at least part of its cross-section arranged in the key channel area near the housing and that with its grooved pin from the area of Locking pin adjusted in the rotational release position overlapped with the core pins. Even with this configuration it is possible to e.g. radially into a longitudinal groove to engage the housing and get it out of such Lock position in a rotational release position to then a twist of the cylinder core with the key cause. The result is a radially less complex overall Solution, taking the areas of the core next to the key channel remain unaffected.
  • the profile cylinder is then particularly in the longitudinal direction comparatively short if the associated key is a with the adjustment pin of the locking part receiving longitudinal groove has actuating edge on the rear side.
  • the length of the profile cylinder is then except by the number of pin tumblers only by the one required for the ring groove Space requirements determined, so that even comparatively short Lock cylinder with security measures according to the invention can be equipped.
  • the locking pin of the locking part longitudinal groove can easily be in the range for the key shaft profile can be arranged, taking the required Weakening doesn't bother here.
  • the locking cylinder it is advantageous to train it so that the spring force generating spring with the locking part coaxially in Core is arranged cylinder spring, which on the one hand Blocking part and on the other hand supported on a closure part, that the key channel of the core at least in the flight of the Locking part locks.
  • cylinder spring which on the one hand Blocking part and on the other hand supported on a closure part, that the key channel of the core at least in the flight of the Locking part locks.
  • Locking part is a part built into the key channel with a bore partially receiving the spring in which there is an abutment pin.
  • the material effort for the additional locking parts is particularly low.
  • the locking cylinder gets by if it is designed this way is that the closure member is a ring rotatable in the housing is that partially picks up the spring and deals with the core turns with.
  • the lock cylinder 10 shown in the figures has regardless of its different representations Housing 11 with a 37 designated only in Figure 3 Housing bore in which a core 12 is rotatably arranged.
  • the housing 11 is intended for a double cylinder and accordingly with one arranged centrally between the two housing halves Groove 38 for a lock bit, not shown Mistake.
  • the core 12 can be rotated with a key 16, which can be inserted into a key channel 13.
  • Vertical to the key channel 13 are core pins in its plane 14 in corresponding bores of the core 12 and housing pins 15 arranged in corresponding holes in the housing 11.
  • the pins 14, 15 are of abutment pins fixed to the housing 39 supported springs 40 spring-loaded and form Pin tumblers, which effectively prevent the core from twisting, if not of the incised 41 Key 16 against their spring load with an incision 41 moved into the only predetermined position are in the parting plane of the pins 14,15 with the outer circumference of the core 12 coincides. In this case, prevent they do not rotate the core 12.
  • Locking parts 17 available, also from the key 16 have to be moved into a predetermined position, so that the core 12 can be rotated in the housing 11.
  • the locking part 17 shown in Figures 1 to 12 is in each case designed as a longitudinally adjustable sliding block, 1 to 8, 9 and 10, and 11 and 12 each different Lock parts 17 show, but each in one Groove 42 of the core 12 are longitudinally adjustable to a limited extent. All different Embodiments of the locking part 17 is common, that they have a radially projecting grooved pin 22, which engages in a longitudinal recess 21 of the housing 11 and therein according to the adjustment of the locking part 17 displaceable in the directions of the key insertion direction 18 is.
  • the cross-section of the grooved pin 22 is matched so that the latter within the annular groove 19 can be adjusted.
  • the annular groove 19 is outside the area of the pin tumblers arranged so that safety of the lock cylinder 10 with respect to its tumblers is not affected by the fact that as a result of the additional Ringnut a pin tumbler should be eliminated.
  • the longitudinal extent of the locking cylinder 10 kept low by the fact that the range of motion of the Locking part 17 overlaps with the area of the pin tumblers.
  • the locking part 17 is in the locked position according to FIG. 3, 4 in an arrangement next to the key channel 13 and above and in addition to the core pins 14 and the associated holes.
  • 9 to 12 is the configuration of the locking part 17 in that it differs is arranged in the area of the key channel 13, namely where the key shoulder is when the key is inserted comes to rest.
  • the locking parts 17 are against the force of a spring 25 from their extreme locking position determined by this spring 25 at least so far that their groove pin 22 for Cover with the annular groove 19 can reach.
  • This position is shown in Fig.6.
  • the key can be inserted 18 inserted keys 16 the core 12 twist and thus the proper unlocking of the associated Effect castle.
  • Figures 2.6 and 8 show, however, that the possibility of movement of the locking part 17 as a result the dimensioning of the associated groove 42 and the longitudinal recess 21 for the grooved pin 22 is larger than it Reaching the rotational release position shown in Fig. 6 would be necessary.
  • the locking part 17 can e.g. in the position shown in Fig.8 are moved in which Groove pin 22 also prevents rotation of the core 12. The security against unlocking is thereby improved.
  • the locking part 17 of Figure 3 shows exemplary dimensions X, Y and Z, which are used to unlock the locking cylinder are decisive. Your change leads to the fact that the lock cylinder 10 each has a different key 16 needed to be unlocked properly. Corresponding also applies to the locking parts 17, 17 'of the others Variants of the figures.
  • the locking part 17 is arranged next to the key channel 13 and requires the key 16 to operate it an intervention in the key channel 13, for which the locking part 17 has an adjusting pin 23 which passes through a longitudinal slot 24 of the core engages in the key channel.
  • the Key 16 has a matched to the adjusting pin 23 Longitudinal groove 28 on, which allows the key 16 in its Insert direction 18 so far that he one hand in the position shown in Fig. 5,6, on the other hand the locking part 17 with an actuating edge 29 of its longitudinal groove 28 adjusted as necessary.
  • the longitudinal groove 28 is required because the locking part 17 is in its locked position the insertion direction 18 at the level of the pin tumblers is arranged.
  • the longitudinal groove 28 provides the necessary freedom. This freedom could, however also by one in the key shoulder Clipping be created. Such a section is for example then necessary if the locking part 17 according to Fig.9 to 12 protrudes into that area of the profile channel 13, which is intended to hold the key shoulder.
  • the length dimensioning this total section is comparative likewise, namely in such a way that the locking part 17 from a locking edge of the key shoulder cutout when whole If necessary, the key slot can be moved into one position can, in which the grooved pin 22 in its rotational release position arrives in the area of the annular groove 19.
  • the locking part 17 by a spring 25 from the rotational release position in the Locked position can be pushed back.
  • the spring 25 is in each case arranged in the groove 42 of the locking part 17.
  • the locking parts 17 of Figures 1 to 8 can only in the Core are installed because the longitudinal recess 21 of the housing 11 does not go through to its lockable end.
  • the locking part 17 is therefore formed in two parts, the Groove pin 22 is a special component, which after Installation of the locking part 17 in the core through the longitudinal recess 21 inserted into a bore of the locking part 17 becomes. The installation takes place e.g. by pressing and / or gluing.
  • the spring 25 as a cylindrical spring is formed, the outer circumference 26 may be larger must, as the width 27 of the longitudinal recess 21, so that the spring 25 remains in the groove 42 of the locking part 17.
  • Fig.9,10 show a closure member 30, which in the Key shoulder receiving area of key 16 is installed in the area of the key channel 13. It is here pressed and sits accordingly.
  • a bore 31 is an abutment pin 32 installed for the spring 25, the other End is supported on the locking part 17.
