Definitions

  • the invention relates to a lock cylinder, which is in particular a profile cylinder.
  • a lock cylinder is for example for a closing device such. a door lock provided.
  • Lock cylinder have a housing in which a cylindrical receiving space is formed for receiving a cylinder core.
  • the cylinder core is rotatably mounted in the receiving space of the housing. Axially through the cylinder core extends through a closing channel for the key. Starting from this closing channel also extend substantially radially through the cylinder core a plurality of first receiving bores in which core pins are arranged. In the housing are also receiving bores in which housing pins are arranged. In a certain rotational position of the cylinder core whose mounting holes are aligned with those of the housing.
  • the housing pins which are spring-loaded in the direction of the cylinder core in the receiving bores of the housing, extending into the receiving holes of the core or core pins into the receiving bores of the housing, so that the cylinder core is secured against rotation. Only when the contact surfaces of all pairs of housing and core pins with the outer surface of the core are aligned after the introduction of the appropriate key, the cylinder core can be rotated.
  • the known lock cylinder are generally considered quite burglar proof, but unfortunately are not always protected from all types of manipulation. So it is possible, for example, with the help of manipulation tools to move all pairs of housing and core pins such that the contact surfaces are aligned with the outer surface of the cylinder.
  • the object of the invention is to provide a lock cylinder with at least one multi-part housing pin, wherein the lock cylinder can be easily installed.
  • the invention essentially relates to the fact that the multi-part housing pin when assembled, is present as a unit.
  • the first pin part is formed as a sleeve, of which the second pin part, which may be formed, for example mushroom-like with shaft, is added.
  • the second pin part is secured against unintentional moving out of the sleeve or in this.
  • the sleeve has a bottom and an opposite open end. In the bottom of the sleeve there is an opening through which an extension of the second pin part protrudes.
  • the second spring which surrounds the second pin part and biases both. Securing the second pin member to the sleeve prevents the second pin member from moving out of the sleeve due to the action of the second spring.
  • the receiving bore further includes a surrounding example of the first spring fixed stop, with the protruding from the bottom of the sleeve or with the outside of the bottom of the sleeve final extension of the second pin part of the housing pin in the event of a due to a manipulation movement the housing pin in the receiving bore impulsively comes into contact.
  • This contacting prevents further movement of the second pin member within the receiving bore, but allows the sleeve to continue to move due to its inertia, thereby eliminating the securement of the second pin member to the sleeve.
  • the advantage of the inventive arrangement of the lock cylinder is initially in the ease of installation when inserting the multi-part housing pin into one of the housing receiving bores.
  • the lock cylinder can be operated and used normally with the housing pin held together.
  • the lock can continue to be operated properly by the associated key when the multi-part housing pin has been "triggered” as a result of manipulation. Because after the "release" of the multi-part housing pin exactly the situation arises, as described in the two previously described documents. Because of the tight tolerances and the low forces acting on the individual pin parts, it is also reliably avoided that the second pin part can be pushed out of the sleeve once again, possibly under tilting and wedging, which would eliminate the manipulation protection.
  • the second pin part is expediently designed in the manner of a mushroom head with a widened head and, on the other hand, a tapered shank.
  • the lower side of the head forming shoulder serves as an attachment for the second spring.
  • the fixed stop in the receiving bore of the housing which accommodates the multi-part housing pin, is expediently designed as a closure pin, with which the receiving bore is closed at its end remote from the receiving space.
  • the housing receiving bores of a lock cylinder are made as through holes extending from the outside of the housing to the receiving space. These holes must be closed after filling the core and housing with the respective pins and springs again.
  • the closure pin has a pin extension or shaft forming the stop, which is arranged axially in the manner of a needle in the receiving bore and the receiving space points.
  • the second pin part can be arranged in the sleeve form-fitting or frictional engagement.
  • a clamping arrangement including the second pin member advantageously has a circumferential circumferential groove, in which by deformation of the circumferential groove surrounding sleeve wall thereby formed mecanicvorwölbung the sleeve partially dips and ensures the securing of the second pin part of the housing pin to the sleeve.
  • the backup can also be done on the extension of the second pin part in or at the opening in the sleeve bottom (clamped or with locking ring).
  • the profile cylinder 10 has a housing 12 and a cylinder core 14, which is rotatably arranged in a receiving space 16 of the housing 12.
  • the cylinder core 14 is provided with an off-center axial locking channel 18, in which the key 20 can be inserted.
  • the cylinder core 14 there are several core pins 22, 24 (in the exemplary embodiment, five core pins in a row) arranged one behind the other in the axial extent of the cylinder core 14, which are located in (first) receiving bores 26 of the cylinder core 14. These receiving bores 26 extend radially through the cylinder core 14 between its closing channel 18 and its outer side 28.
  • the housing 12 In the housing 12 are also several (second) receiving holes 30, the number and arrangement of the number and arrangement of the first mounting holes 26 are the same.
  • the second receiving bores 30 extend relative to the receiving space 16 of the housing 12, radially and are arranged in the rotational position of the cylinder core 14 of FIG. 1 in alignment with the first receiving bores 26.
  • housing pins 32,34 While, as already mentioned above, in the first mounting holes 26, the core pins 22,24, which may be different lengths are arranged, 30 housing pins 32,34 are arranged in the second mounting holes, which are biased by helical compression springs 36 against the core pins 22,24 are.
  • the helical compression springs 36 press on the housing pins 32,34 the core pins 22,24 against the located in the closing channel 18 ends of the first mounting holes 26 (see Fig. 1).
  • the housing pins 32, 34 extend both within the first and second receiving bores 26, 30, so that rotation of the cylinder core 14 by the housing pins 32, 34 is prevented.
  • the core pins 22,24 are moved radially outwardly, by the key 20.
  • the vote of the width of the key 20 along the length thereof is so matched to the length of the core pins 22,24 that this with inserted key 20 with the outside 28 of the cylinder core 14 are aligned.
  • the housing pins 32,34 are completely moved back into the second mounting holes 30, so that the cylinder core 14 can now rotate.
  • the peculiarity of the profile cylinder 10 shown in FIG. 1 is that one of the housing pins 32 is made of several parts, for assembly purposes, this multi-part housing pin 32 is designed as a unit whose parts can move apart in the event of manipulation and thus act, as it is in DE-B-103 49 349 and DE-U-20 2004 008 507 is described.
  • the first housing pin 32 seen from the opening of the closing channel 18 is formed in several parts, as shown in Fig. 2.
  • the multi-part housing pin 32 has an outer pin member 38 which is formed as a sleeve 40 with a bottom 42 at its one axial end 44 and open at its other axial end 46.
  • an inner second pin part 48 Inside the sleeve 40 is an inner second pin part 48, which has a shank 50 with a widened head end 52. Between the widened head end 52 of this pin member 48 and the bottom 42 of the sleeve 40 is supported Compression spring 54 which is stronger than the spring 36 in the housing receiving bore 30.
  • the shaft 50 of the inner pin member 48 has at its end remote from the widened head end 52 a tapered (pin) extension 56 which through an opening 58 in the bottom 42nd protrudes from the sleeve 40 or at least is dimensioned so that it is flush with the outer side 60 of the bottom 42 or when the housing pin 42 is present as an assembled unit, as shown in Fig. 2.
  • This one-piece unit is realized by a frictional connection between the outer pin member 38 and the inner pin member 48, which withstands the compression spring 54.
  • the head end 52 is held in the sleeve 40 near its open end 46 by clamping.
  • the head end 52 has a circumferential circumferential groove 62, in the partially or over the entire circumference wall material of the sleeve 40 is slightly pressed (see the inner protrusion 64 on the inside of the sleeve 40).
  • Alternative deadlocks of both pin parts 38,48 are also possible.
  • the receiving bore 30 has a stop 66 which is fixedly arranged.
  • the stopper 66 is formed as a pin-shaped extension 68 of a closure pin 70 of the receiving bore 30.
  • stop 66 Surrounded by the helical compression spring 36 stop 66 cooperates with the pin extension 56 of the housing pin 32 to "trigger" in the case of manipulation, the housing pin 32 insofar as the clamping of the two pin parts 38 and 48 is released and the housing pin 32 thereafter a state as described in detail in the above two references.
  • the multi-part housing pin 32 can be pre-assembled as a unit, as shown in Fig. 2, handle comfortably, so that the assembly of the lock cylinder 10 with multi-part housing pin 32 is the same as in a conventional lock cylinder. Also, the operation of the present (as a unit) multi-part housing pin 32 is equal to that of a conventional one-piece housing pin. This is shown in FIGS. 2 and 3, where Fig. 2 shows the situation in which the matching key is not in the closing channel, while Fig. 2 illustrates the state in which the matching key is inserted.
  • the housing pins of the lock cylinder are placed in movements within their mounting holes, which result in much greater and a larger stroke than is the case with the proper use of the lock cylinder.
  • the multi-part housing pin 32 comes in the event of a manipulation attempt in contact with the stopper 66 within its receiving bore 30. This is shown in Fig. 4. Due to the pulse-like impingement movement of the housing pin 32 on the stopper 66 and the inertia of the sleeve 40, the clamping force between the two housing pin parts 38 and 48 is released, so that the two housing pin parts 38 and 48 move apart under the action of the spring 54. This is shown in FIG.
  • FIG. 6 shows this in the event that no key or a mismatched key is in the closing channel.
  • the multi-piece housing pin 32 behaves in its extended state like a normal housing pin.
  • Fig. 7 shows the situation in which the extended length of the housing pin 32 when inserting the matching key due to the core pin 22 as far enough into the receiving bore 30 is moved into that the core 14 can rotate.
  • Fig. 8 finally shows the operation of the multi-part apart moving housing pin 32 as tamper protection.
  • the radial game between the two pin parts 38 and 48 of the housing pin 32 allows a (minor) rotation of the core 14 relative to the housing 12, even if the inner pin member 48 is still in the core-receiving bore 26, while the sleeve-shaped outer pin member 38 already completely in the Receiving bore 30 of the housing 12 is inserted.
  • the lock cylinder 10 the same situation arises as is given when the entire housing pin 32 including the widened head end 52 of its inner pin part 48 is located in the receiving bore 30. If the person manipulating the profile cylinder 10 now wishes to rotate the core 14, this only happens within an extremely small rotation angle range.
