Definitions

  • the invention relates to a lock cylinder with a rotatable core in a housing and with an electromagnetically activatable locking mechanism for selectively blocking or releasing the movement of the core.
  • lock cylinders are commonly used in today's locking systems and are known for example from DE 199 01 838 A1.
  • a locking bolt is slidably disposed in a bore of the housing and is biased by a spring element in the direction of the core.
  • the core has pockets for receiving the locking bolt.
  • an armature connected to the locking bolt is pressed against an electromagnet of the electromagnetically activatable locking mechanism.
  • the electromagnet is energized and holds the armature.
  • the locking bar is held within the housing, and the core can be rotated relative to the housing.
  • the locking mechanism In the absence of locking authorization, the locking mechanism is not energized and the locking bar passes through the force of the spring element upon rotation of the core in one of the pockets of the core and blocks its further movement.
  • the solenoid may possibly be magnetized such that the locking bar is retained within the housing and releases the movement of the core.
  • the invention is based on the problem, the lock cylinder of the type mentioned in such a way that its unlocking is reliably prevented even in the presence of a strong magnetic field.
  • the housing or the core has a pocket on the opposing component for fully receiving a blocking element, that the opposing component in its at least one rotational position of the core in the pocket at least one partially receiving the blocking element Lock pocket has, that the bag in the intended mounting position is open at the top and that the blocking element is made of a magnetizable material.
  • the presence of a strong magnetic field leads to the movement of the blocking element into the blocking pocket.
  • the locking pocket receives the locking element only partially, the locking element is in the parting plane between the housing and core and blocks the movement of the core regardless of the position of the locking bar of the electromagnetically activatable locking mechanism.
  • the blocking element is held in the pocket by gravity. Therefore, without the external magnetic field in the lock cylinder according to the invention as in the known lock cylinder, the movement of the core is controlled exclusively via the electromagnetically activatable locking mechanism.
  • Falling out of the blocking element from the pocket during a rotation of the core can be according to another Advantageous development of the invention simply prevent when the bag is arranged in the housing and the lock pocket in the core.
  • the core has, according to another advantageous embodiment of the invention, a predetermined breaking point, if a plurality of locking pockets are arranged as a broken groove on the circumference of the core.
  • This predetermined breaking point results in a tensile test of the core to its break, so that the locking mechanism arranged behind the predetermined breaking point reliably holds the lock cylinder according to the invention in its closed position.
  • the blocking element is pulled reliably according to another advantageous embodiment of the invention in the locking pocket when the core is made at least in the region of the pocket or the locking pocket of a magnetizable material.
  • the area made of magnetizable material is also magnetized and pulls the blocking element into the blocking pocket.
  • the lock cylinder according to the invention is reliably blocked even at low magnetic fields when the bag has a ramp pointing towards the front side of the housing.
  • the bag has a funnel-shaped extension as a circumferential ramp.
  • the locking element In an attempted rotation of the core after the introduction of a magnetic field, the locking element is held particularly reliable in the locking pocket when the locking pocket of the ramp has opposing, pointing tangentially to the core widenings.
  • the lock cylinder according to the invention can be manufactured particularly cost-effectively, if the blocking element is designed as a ball.
  • the rotation of the core in an external magnetic field can be according to another advantageous embodiment of the invention simply limited by a ring of locking pockets.
  • a tightening of the locking element in the locking pockets can be ensured according to another advantageous embodiment of the invention, when individual locking pockets are separated by constrictions.
  • the constrictions form magnetic poles in an external magnetic field, which reliably attract the blocking element.
  • Figure 1 shows a lock cylinder with a rotatable in a housing 1 core 2 in a longitudinal section.
  • the locking cylinder has an electromagnetically activatable locking mechanism 3 with an axially displaceably arranged in the housing 1 and biased by a spring element 4 in the direction of the core 2 locking bolt 5.
  • the locking mechanism 3 has an electromagnet 6, which pressed the locking latch 5 in one in the housing 1 To hold a position.
  • the locking bar 5 is partially in a recess 7 of the core 2 and thus blocks the movement of the core 2 relative to the housing 1. This indicates the basic position of the lock cylinder.
  • the locking bar 5 can be pressed, for example, via a key inserted into a closing channel 8 of the core 2 or by a slight rotation of the core 2 into the housing 1.
  • the electromagnet 6 keeps the locking bolt 5 in a completely located in the housing 1 position and therefore allows the rotation of the core 2 relative to the housing 1.
  • the core 2 next to the recess 7 has a circumferential ring locking pockets 9.
  • the locking pockets 9 are separated by constrictions 10 from each other.
  • the constrictions 10 are formed as constrictions of a circumferential, the locking pockets 9 forming groove.
  • the housing 1 has the rim locking pockets 9 opposite a pocket 11 for receiving a locking element 12.
  • the blocking element 12 is higher than the locking pocket 9, so that the locking pocket 9, the blocking element 12 can only partially accommodate.
  • the ring of the locking pockets 9 is arranged in an insert 13 made of a magnetic material of the core 2.
  • the blocking element 12 is also made of a magnetic material. At the lowest point of the pocket 11 close in the direction of the end face of the core 2 facing and pointing away from the front ramps 14 at.
  • the blocking element 12 is held by gravity in the pocket 11.
  • the mobility of the core 2 relative to the housing 1 is thus dependent solely on the activation of the locking mechanism 3. If you try by applying a strong magnetic field to put the locking mechanism 3 out of force and thus extract the locking bar 5 from the recess 7 of the core 2, the magnetic field is simultaneously introduced into the insert 13 of the core 2 and into the blocking element 12.
  • the blocking element 12 is pulled into one of the locking pockets 9 of the core 2. Since the blocking element 12 is larger than the blocking pocket 9 is deep, the blocking element 12 comes to rest in the parting plane between the housing 1 and the core 2 and blocks the movement of the core 2.
  • FIG. 2 shows the lock cylinder of Figure 1 in a sectional view taken along the line II - II in the illustrated basic position in which the locking element 12 is located in the pocket 11.
  • FIG. 3 shows the lock cylinder from FIG. 2 when an external magnetic field is applied and subsequent rotation of the core 2. It can be seen that the blocking element 12 is drawn into one of the locking pockets 9 by the magnetic field and held in the parting plane between the housing 1 and core 2 , This blocks the further movement of the core 2.
  • FIG. 4 shows a further embodiment of the lock cylinder in partial section, in which the locking pockets 9 have tangential widenings 15 at their ends pointing in the longitudinal direction of the core 2. Furthermore, the locking pockets 9 have a pointing in the direction of the lowest point of the pocket 11 projection 16.
  • the blocking element 12 is either pushed away from the front side of the core 2 or attracted to this and rolls while the ramp 14 of the pocket 11 along , It gets into the locking pocket 9 and is caught in a rotation of the core 2 in the tangential broadening 15.
  • the core 2 and the insert 13 with the locking pockets 9 are shown uncut.
  • Figure 5 shows another embodiment of the lock cylinder, in which the locking pockets 9 are formed straight in the axial direction of the core 2 and also have a pointing in the direction of the lowest point of the pocket 11 projection 17.
  • the pocket 11 and the locking element 12 are formed as described in the embodiment of Figure 4.
