Definitions

  • the invention relates to a profile lock cylinder with a cylinder housing, the first housing part containing a first axial bore and a cylinder core axially immovably mounted therein as well as spring-loaded tumbler elements, and a connecting bar thus leaving a recess for the lock bit rotatable by the cylinder core there is an integrally connected second housing part with a second axial bore running coaxially with the first axial bore, the cylinder core containing a key channel running in the longitudinal direction for receiving a key provided with incisions and further tumbler elements which, together with the tumbler elements accommodated in the first housing part, result in the rotational mobility of the cylinder core enabling release position are to be moved.
  • Profile lock cylinders of this type are generally known for security locks, in both so-called half-cylinder and double-cylinder shapes.
  • the second housing part is made very short axially and its correspondingly short axial bore only serves to better support the locking bar, while in the double cylinder the second housing part serves to accommodate a further cylinder core and is designed in accordance with the former housing part.
  • the axial bores in the two housing parts run coaxially with one another and are continuously smooth-walled, just like the cylinder cores stored therein.
  • the associated key has such incisions that the tumbler elements, which usually consist of housing pins and core pins, are shifted against the spring load with the help of this key to such an extent that the separation points between each housing pin and a core pin match the interface between the cylinder core and the cylinder housing. Then the cylinder core can be turned with the key and the lock bit located on the core actuates the associated lock either in the opening or closing direction.
  • the tumbler elements which usually consist of housing pins and core pins
  • One method of forcibly opening the lock without an associated key is to pull out the cylinder core by force, thereby creating access to the lock bit and thus opening the lock.
  • This violent pulling out takes place, for example, by means of a corkscrew-like cutting element, for example a screw, which is screwed into the key channel and is thus firmly anchored to the cylinder core in such a way that it can be pulled out of the cylinder housing.
  • a corkscrew-like cutting element for example a screw
  • the locking tumbler pins are sheared off. This cannot be prevented by a circlip serving to axially fix the rotatable cylinder core in the cylinder housing.
  • the invention has for its object to improve a profile lock cylinder with two coaxially arranged on both sides of a locking bar, one-piece housing parts while maintaining a simple structure so that a key insertion side violent pulling out of a cylinder core from its cylinder housing part is not possible.
  • This object is achieved in that on the first housing part a radial annular projection is present on the key insertion side, which engages over part of the end face of the cylinder core, and in that the cylinder core can be installed through the second axial bore of the second housing part into the first axial bore of the first housing part.
  • the cylinder core is prevented from being pulled out by an annular projection provided on it on the key insertion side.
  • the ring projection on the cylinder core can be made solid in the desired manner. Since the cylinder core with the associated cylinder housing part is assembled from the lockable side, the ring projection can therefore be designed with the safety conditions in mind, regardless of the installation process.
  • the ring projection can also consist of hard metal, for example.
  • the ring projection on the key insertion side can be designed to be closed all around and the key channel on the key back side can be filled by a web, the height of which is equal to the height of this ring projection.
  • the all-round closed design of this ring projection ensures additional pull-out strength and requires a key back closed key channel, for which a web in the cylinder core is used, with which the housing pins are held down when the cylinder core is turned.
  • the web is in one piece with the cylinder core and pin bore sections located in the web are completely filled. With this configuration of the cylinder core, it can be produced in the usual way, and the production of the holes for the pin tumblers does not need to be changed either. It is possible, for example, to produce these pin bores from above through the cylinder housing and the cylinder core and, for example, to solder the pin bore sections that are no longer required.
  • the ring projection on the first cylinder housing part can be slit key width at least in front of the section of the key channel receiving the key back and the key can have a slot receiving this ring projection when the cylinder core rotates.
  • the key channel can have a conventional size and, in particular, be open at the top, so that the back of the key serves to hold down the housing pins when the cylinder core is rotated.
  • the locking cylinder 10 shown in FIG. 1 is a half cylinder approximately of the profile of FIG. 4.
  • the locking cylinder 10 has a cylinder housing 11 which consists of a first housing part 11 'and a second housing part 11' 'which are connected via the connecting web 11' ' 'are connected.
  • the first housing part 1 ' contains a first axial bore 27 and a cylinder core 12 which is axially immovably mounted therein.
  • In the connecting web 11 '' ' there is a threaded bore 13 for the engagement of a fastening screw, with which the locking cylinder 10 is fixed in a lock housing.
  • the bearing of the locking bar 15 is provided with bearing rings 16 on both sides of the locking bar 15, and also the second axial bore 33 in the leg 32 of the second housing part 11 ′′.
  • the storage of the locking bar 15, its design and its assembly with the cylinder core 12 are conventional and are therefore not shown in detail.
  • the cylinder housing part 11 has a plurality of pin bores 17 arranged side by side in a row, each of which receives a spring 18 which is supported at one end on the bore bottom 19 and at the other end on a housing pin 20.
  • the housing pin 20 transmits the force of the spring 18 to a core pin 21 which projects into a key channel 22 of the cylinder core 12.
  • the key channel 22 receives the key shaft 23 of the key 24, so that its key incisions 25 reach the core pins 21 in a predetermined position. Since the core pins 21 are of different lengths and the depth of the key incisions 25 is specifically matched to the different length of the core pins 21, these are held at different heights by the key shaft 23 or by the key incisions 25 on the key side in the manner shown in FIG. 1, however so that the core pins 21 on the housing pin side Project axially equally far and, in particular, complete with the outer circumference of the cylinder core 12.
  • the core pin-side ends 26 of the housing pins 20 also terminate with the inner circumference of the bore 27 of the cylinder housing 11 which rotatably supports the cylinder core 12, so that the cylinder core 12 can be rotated using the key 24, which due to its rotationally fixed connection to the lock bit 15 increases whose rotation and thus leads to a lock actuation.
  • the key 24 can be inserted exactly into the position shown in FIG. 1 in the key channel 22, the key 24 has an insertion stop 28 and the cross section of the key 24 has key notches 29, so that only one key 24 with one through the notches 29 conditional shaft profile can be inserted into the key channel 22.
  • the profile of the key channel 22 is, for example, similar to that of the channel 22 in FIG. 4.
  • the cylinder housing part 11 ' On the key insertion side, the cylinder housing part 11 'has an annular projection 30 which forms an abutment for the insertion stop 28 of the key 24 and moreover prevents the cylinder core 12 from being pulled out against the direction of insertion of the key 24 by force.
  • the ring projection 30 thus reduces the diameter of the bore 27 of the cylinder housing 11.
  • the cylinder core 12 must be installed in this bore 27 on the lockable side, that is to say in FIG. 1 from right to left through the axial bore present in the second axially short housing part 11 '' 33 through.
  • the back 35 of the key 24 is not quite as high as in the case of a key of a locking cylinder without a ring projection.
  • the key channel 22 is not completely through the Key back 35 filled, which consequently can not ensure that the housing pins 20 are held down by the key 24 at its corresponding rotational position.
  • the key channel 22 is filled on the key back side by a web 34 which guides the key shaft 23 on the key back 35.
  • the web 34 serves to hold down the housing pins 20 when the key 24 is in a corresponding rotational position.
  • the web 34 is produced in one piece with the cylinder core 12.
  • the ring projection 31 on the closable side thereof with which the cylinder core engages in a corresponding, not specified ring groove of the cylinder housing part 11 ', so that it assumes the desired position in which its core pins 21 with the Align housing pins 20.
  • this annular projection 31 cannot be reached by unauthorized persons and therefore cannot be drilled out from the outside.
  • the axial bore 33 present in the second housing part 11 ′′ or in the leg 32 has a diameter which is at least equal to the outer diameter of the ring projection 31 in order to be able to insert the cylinder core 12 with the ring projection 31.
  • Such a dimensioned bore 33 is unproblematic in the profile half cylinder shown in FIG. 1.
  • the second cylinder core to be installed must also have a correspondingly larger diameter.
  • the pin bores 17 are only partially occupied by a spring 17, a housing pin 20 and a core pin 21. They are made by, for example is drilled in the direction b through the cylinder housing part 11 'and the cylinder core 12.
  • the resulting bore sections 36 in the cylinder housing part 11 'and 37 in the cylinder core 12 above the key spine 35 must be closed so that the core pins 21 do not turn into open bore sections 36 of the cylinder housing 11 when the core 12 is rotated, and thus the housing pins 20 do not enter open bore sections 37 of the cylinder core 12 and prevent its further turning. This filling of the relevant bore sections 36, 37 takes place, for example, by soldering.
  • the half cylinder shown in FIGS. 2 to 4 consists essentially of the same components as the half cylinder of FIG. 1.
  • the ring projection 30 on the key insertion side has a slot 38, so that the key back 23 has a customary height and can be inserted unhindered into the key channel 22 by the ring projection 30.
  • the key 24 is provided with a slot 39, the depth and width of which are matched to the height and width of the ring projection 30.
