Definitions

  • the invention relates to a cylinder lock with a cylinder housing and a cylinder core rotatably mounted therein, which has a key channel running in its axial direction, with a lock bit rotatably mounted in the cylinder housing, coupled to the cylinder core, with several in alignment in the cylinder housing and in the cylinder core, perpendicular to the cylinder core axis running bores are attached, which extend into the channel and in which housing pins of the same length and core pins of different lengths are spring-biased towards the channel, a first parting line being formed between the cylinder housing and the cylinder core, which pass through the housing pins without a key inserted , and wherein the ends of the core pins interact with the locking notches of the key so that when the key is inserted, the pins are moved in their axial direction into a position in which the contact ends of all core and Ge pins in the first parting line, thereby allowing the cylinder core and the locking bar to rotate.
  • Known cylinder locks of this type offer only limited security against burglary.
  • the cylinder core is directly coupled to the lock bit.
  • a burglar could then, for example, insert a strip of hard material into the key channel and use it to move the core pins and the housing pins down so far that the core pins cover the joint between the cylinder core and the cylinder housing.
  • the core pins can then be sheared off in the parting line by forcible rotation of the strip, for example by means of a knob welded to it on the outside, so that the cylinder core and thus also the locking bit can be rotated and the door can thus be opened.
  • the invention has for its object to provide a cylinder lock of the type mentioned so that increased security against burglary is guaranteed.
  • a sleeve is used for coupling the cylinder core to the lock bit, which is rotatably mounted between the cylinder core and the housing and thereby forms a second joint to the cylinder core in addition to the first joint to the cylinder housing, and that the core pins one have lower strength than the sleeve and the housing pins.
  • the invention requires that the contact ends of the core and cylinder pins lie in the first parting line between the cylinder housing and the sleeve so that the cylinder core can be rotated, the core pins taking the sleeve with them, which in turn is connected to the locking bit is coupled.
  • a break-in is made more difficult.
  • the core pins and the housing pins are moved so far that their contact ends are in the area of the sleeve. A violent rotation of the wrong key or the metal strip would then cause the core pins to shear at the joint between the sleeve and the cylinder core.
  • the second way be is that the core pins and the housing pins are moved so far that their contact surfaces are in the cylinder housing. Even in this case, the core pins will shear off due to their lower strength in the second joint between the sleeve and the cylinder core during violent rotation, so that again the cylinder core can be rotated, but not the sleeve coupled to the lock bit.
  • the core pins In order to facilitate the breaking off of the core pins, it is expedient to provide the core pins with a predetermined breaking point, which preferably consists of a section with a smaller diameter. In this case, in order to avoid entrainment of the sleeve due to remaining remnants of the sections with a smaller diameter, it is expedient to provide slots in the circumference of the sleeve parallel to the axis of the core pins, the width of which corresponds approximately to the width of the sections with a reduced diameter.
  • the housing pins and the core pins are preferably dimensioned such that their contact surfaces lie in the second parting line when the key is not inserted. Then it is possible to turn the cylinder core with a wrong key, which can irritate a burglar because the rotation of the cylinder core is not possible with the usual cylinder locks.
  • housing pins and the core pins can also be dimensioned such that at least one housing pin passes through both parting lines when the key is not inserted, while the contact ends of the other pairs of pins lie in the second parting line.
  • the invention provides that near the front end of the housing in the cylinder core on the one hand and in the cylinder housing on the other hand, an annular groove for receiving a retaining ring is attached, which is so deep in the housing that it can accommodate the retaining ring in its spread state and the Cylinder core with the sleeve pushed thereon can be inserted through the locking ring into the cylinder housing, and that a bore is made in the cylinder housing through which a pin can be inserted from the outside between the ends of the expanded locking ring in order to keep it spread when the cylinder core is inserted.
  • additional security can be achieved in that the securing bolt is additionally assigned to the housing pins, and in that recesses are provided on the housing pins and projections on the securing bolt or vice versa are provided such that the axial displacement of the securing bolt is only released when the key is inserted is.
  • the securing bolt extends transversely to the housing pins and has sections with a larger diameter between the housing pins, and that the housing pins have areas with a smaller diameter which are at the same height when the key is inserted and the path for the sections with a large diameter release the safety bolt for its axial displacement.
  • a cylinder core 2 is rotatably mounted in the usual manner, in which a channel 3 for inserting a key 4 is attached. While in known cylinder locks the cylinder core 2 is coupled directly to the lock bit 5, in the embodiment shown, a sleeve 6 is used for coupling the cylinder core 2 to the lock bit 5, which sleeve is rotatably mounted between the cylinder core 2 and the cylinder housing 1 and e.g. is connected to the locking bit 5 by means of a pin 7.
  • the cylinder core 2 and in the cylinder housing 1 four mutually aligned bores are provided, which run perpendicular to the cylinder axis, which extend into the key channel 3, and in which - as usual - housing pins 8 of the same length and core pins 9 of different lengths are slidably mounted and in the direction of the key channel 3 are biased by springs 10.
  • the cylinder core 2 and the cylinder housing 1 form a first parting line, which is penetrated by the housing pins 8 when the key is not inserted, so that the cylinder core 2 is blocked against rotation.
  • the core and housing pins are shifted so far that their contact ends are all in the parting line and thus the rotation of the cylinder core 2 with the locking bit 5 is released.
  • the core pins 9 can be sheared off in the parting line by force and thereby a rotation of the cylinder core 2 be forced with the lock bit 5.
  • the sleeve 6 provided according to the invention makes it impossible or at least very difficult to actuate the locking bar 5 after the use of force.
  • the core pins 9 are preferably dimensioned such that, in the absence of a key 4, the contact surfaces of all core and housing pins lie in the second parting line formed between the sleeve 6 and the cylinder core 2.
  • the cylinder core can be rotated without a key 4, but the lock bit 5 cannot be moved because the connection to the cylinder core 2 is missing.
  • the contact surfaces of all core pins 9 and housing pins 8 are moved into the first parting plane between the sleeve 6 and the housing 1, which is shown in FIG. 1.
  • the cylinder 2 is coupled to the sleeve 6 via the core pins 9, so that it can be rotated with the cylinder core 2, whereby the locking bit 5 connected to the sleeve 6 can also rotate.
  • the contact ends of all the pins 8 and 9 can still be located within the sleeve 6, so that the core pins 9 pass through the second parting plane, but the case is more likely that at least some of the core pins 9 also penetrate the first parting line between the sleeve 6 and the cylinder housing 1.
  • the core pins 9 of the second joint between the cylinder core 2 and the sleeve 6 shear off if one ensures that the housing pins 8 and the sleeve 6 have a higher strength than the core pins 9 then the cylinder core 2 are rotated, but the sleeve 6 is not taken along, ie the lock bit 5 cannot be rotated.
  • the contact ends of pins 8 and 9 are in the second parting line, i.e. the cylinder core 2 is thus freely rotatable, preferably in the cylinder housing a locking pin 11 which is displaceable in its axial direction and which engages with one end by spring force in a notch of the locking bar 5, the notch being dimensioned so flat that when the locking bar rotates through the sleeve 6, the tip of the locking bolt 11 can slide out of the lock bit 5.
  • This security bolt can be used as an additional means of increasing the security of the lock against burglary. As can be seen from FIGS.
  • annular recesses 12 are provided on the housing pins 8 and annular projections on the securing bolt 11, or vice versa, in such a way that the securing bolt can only be displaced axially when the key 4 is inserted and thereby the recesses 12 in the housing pins in the form of areas with a smaller diameter are all at the same height.
  • the invention provides for the fuse to be provided near the front end of the housing.
  • an annular groove 14 is provided for receiving a retaining ring 15, which is so deep in the housing that it can accommodate the retaining ring 15 in its spread state. This spreading is first effected after inserting the locking ring into the ring groove using a suitable tool.
  • each locking unit has its own sleeve 6, which of course must not then be connected directly to the locking bit, because each locking unit must be operable independently of the other.
  • the coupling between the sleeves 6 and the cylinder cores 2 is carried out here by two pairs of locking pin pins 17 and core pins 18, wherein the core pins can be in one part or - as shown - also in three parts. From Fig.
  • the prevention of rotation of the cylinder core 2 when the key is missing can also be prevented by the outer housing pin 8 being somewhat longer than the other housings pins is made so that it passes through the second parting plane between the sleeve 6 and the cylinder 2 and thus is not rotatable even when the key 4 of the cylinder core 2 is missing.
  • the core pins 9 should have a lower strength than the sleeve 6 and the housing pins 8. This can be done on the one hand by the choice of the material, but can also - as shown in Fig. 4, a predetermined breaking point in the form of sections 19 with a smaller diameter can be provided in the core pins, the sections 19 should be arranged so that they when inserted Dummy key lie in the second parting line between the sleeve 6 and the cylinder core 2.
  • slots 20 are provided in the circumference of the sleeve 6, parallel to the axis of the core pins 9, the width of which corresponds approximately to the width of the sections 19 with a reduced diameter, the slots 20 of course do not extend over the full circumference of the sleeve 6.
  • the coupling between the sleeves 6 of the two clamping units and the locking bit 5 is designed as a sliding coupling.
  • the two clutch disks 21 are shifted to the right, the two clutch disks 21 always remaining positively connected to the sleeves 6, but the right clutch disk is released from the positive engagement shown in FIG. 9 with the lock bit and thus the left locking unit Lock bit 5 can operate.
  • the locking back to the other side is achieved by inserting the key into the right locking unit.
  • the pin 28 is pushed upwards by means of a spring and over a conical surface, which is located in the middle of this pin, the pins 27 will snap into the recesses provided for this purpose in the housing 1 and the lock bit 5 secure against shifting.
