Definitions

  • the invention relates to a lock cylinder with a a cylinder housing with a rotatably mounted cylinder core in particular profiled key channel and with at least an electric rotary drive in the cylinder housing and a locking body cooperating with the rotary drive between the cylinder housing and the cylinder core.
  • locking cylinders are usually in the frame a locking system needed that opened with the flat key can be.
  • a locking system needed that opened with the flat key can be.
  • an additional electronic criterion or Lockout secret via a transceiver signal or a code transmitter expedient in the key to make a plant special to provide a high level of security and, if at all, they too to be able to expand later.
  • an electromagnetic device Lock a lock cylinder known to be a small one electromagnetic rotary actuator in the cylinder housing approximately in has the position of a housing pin.
  • the rotary actuator also works with known solenoids a locking body together, which is locking in the cylinder core intervenes and is prevented from retreating by the rotary drive becomes. Only in a certain rotational position of the rotor Rotary drive, which essentially corresponds to an electric motor, the locking body can be spring loaded Immerse advanced locking position in a recess of the rotor and reject from the cylinder core.
  • the invention aims to provide a lock cylinder electromechanical locking on a different locking principle without inclined surface in the locked position create.
  • the locking body e.g.
  • a circular cylindrical one Pen therefore moves out of the locked position for the purpose the release does not go back, but twists e.g. around 90 °, so that the front profile of the locking body a Pass the stop of the cylinder core as it rotates leaves.
  • the profile of the locking body in a housing ring groove lies and at least one protrusion on the cylinder core, for example, a radially aligned bolt in the housing ring groove engages and when the profile is in the release position at least aligned with the housing ring groove or in the Locked position engages in the housing ring groove and blocks it.
  • the cylinder core remains unchanged.
  • an embodiment variant is characterized in that that the profile, for example a dovetail profile or hammer head profile, in a recess in Cylinder core engages, in which the locking body e.g. by 90 ° is freely rotatable and preferably diametrically in Connect the direction of rotation of the cylinder core grooves Cross section or entry cross section with the profile in the Release position of the blocking body is aligned and in the blocking position at the out of alignment position, e.g. by 90 °, twisted transverse position of the locking body is locked.
  • the profile for example a dovetail profile or hammer head profile
  • the locking body e.g. by 90 ° is freely rotatable and preferably diametrically in Connect the direction of rotation of the cylinder core grooves Cross section or entry cross section with the profile in the Release position of the blocking body is aligned and in the blocking position at the out of alignment position, e.g. by 90 °, twisted transverse position of the locking body is locked.
  • the locking body protruding into the recess of the cylinder core is not withdrawn for release, but twisted so that he or his end face or head end with the diametrically extending profiling one on the side Circumferential direction of the cylinder core extending groove in the Core rotation reaches through.
  • the locking body axially spring-loaded on a driver of the rotary drive is stored and if the groove or the grooves on both sides the recess to the outer surface of the cylinder core leak out, the locking body runs out of the interior of the cylinder core out after by its rotation of the cylinder core has been released.
  • the locking body enters the housing against spring force and is then on the head side in the course of Rotation on the outer surface of the cylinder core. So that is it is not necessary with a 360 ° rotation of the cylinder core, the key back to the locking body profile accordingly profile, because the locking body runs over the back of the key at the core rotation, towards the end of the 360 ° rotation run back into the recess. In this the Locking body rotated from the rotary drive to the locked position become.
  • a particularly useful development of the invention is that the locking body against in its locking position a retreat is locked against the spring force, in particular a projection of the locking body in the Locked position an axial contact surface on the cylinder housing or on the cylinder core, especially in the interior of the recess, spreads.
  • the head of the locking body in the recess against receding by reaching behind of a profile in the cylinder core in its axial Position held.
  • this measure leaves one rotation e.g. by 90 °.
  • FIG. 1 shows a cross section through a locking cylinder in the release position
  • FIG. 2 shows the locking cylinder according to FIG. 1 3 shows a variant of FIG. 1 4
  • the locking cylinder according to FIG. 3 5 a further variant of FIG. 1 in 6, a detail from FIG. 5 in an exploded oblique view
  • 7 shows the locking cylinder according to FIG. 5 in the release position
  • FIG. 8 shows a detail from FIG. 7 in Exploded oblique view.
  • a locking cylinder comprises a cylinder housing 1 in which a cylinder core 2 is rotatably supported. Between the cylinder housing 1 and cylinder core 2 are in the housing and core holes several spring-loaded shared tumbler pins in known Way provided by the mechanical part (key bit with serrations) of a flat key can be rotated so that the cylinder core 2 can, if not other locks come into effect.
  • a lock is an additional measure in one conventional mechanical lock cylinder subject of the invention.
  • a rotary actuator in an enlarged cylinder housing bore 3, such as an electric motor, the rotor of which rotates 90 ° back and forth.
  • the rotary drive 3 is via a coupling piece 4 with a locking body 5 rotatably connected.
  • the coupling piece 4 is omitted when the locking body 5 cooperates directly with the rotor of the rotary drive.
  • the cylinder housing 1 there is an annular groove 6 which the cylinder core 2 in the cross-sectional plane of the rotary drive 3 and the locking body 5 surrounds. A protrudes into this annular groove 6
  • the locking body 5 has a transverse to the front or head its axis of rotation aligned profile 10, which in the 1 to 4 is designed as a U-shaped incision. This Profile is equal to or larger than the cross-sectional profile the annular groove 6, in which the bolts 7 and 8, 9 dip.
  • the Rotary drive 3 can rotate the locking body 5 in two positions, namely with its profile 10 m longitudinal direction to the groove or in the transverse direction to the groove. In the longitudinal direction according to FIG. 1 and 3 aligns the profile 10 with the groove 6 and sets the groove 6 sort of gone.
  • the cylinder core 2 can be turned because the bolt or bolts 7 and 8, 9 the locking body 5 can pass unhindered.
  • the annular groove 6 is between FIG the two bolts 8, 9 blocked and the cylinder core 2 can not be rotated or to a very small extent.
  • a small Rotation may be desirable, on the one hand, to perform a change if necessary to allow and / or to ensure that for recognizing a code, e.g. one Transceivers, necessary response time at the key lock in the comparison circuit associated with the lock cylinder is available.
  • the rotary drive 3 rotates one Locking body 11, which has a profile 10 on the end face, which 6 or 8 very clearly as a dovetail or Hammer head profile is recognizable.
  • This locking body 11 could engage in an annular groove in the cylinder core 2. It should then, however, each key in the back of the key Groove cross section have at least corresponding recess.
  • This embodiment goes beyond and forms a groove 12 in the cylinder core 2 only over a portion of the circumference of the cylinder core 2, the groove 12 crescent-shaped runs out against the full cylinder core diameter.
  • the Locking body 11 is rotationally fixed on the rotary drive 3, but against the force of a spring 13 is retractable.
  • the Rotary drive 3 influences or hinders pushing back the locking body 11 in any way, because only the crescent-shaped groove 12 causes rotation of the cylinder core 2 an insertion of the already in the open position twisted locking body 11.
  • the locking body 11 engages on the head side with its profile 10 in a recess 14 of the cylinder core 2, to which the groove 12 connects on both sides. While the recess 14 rotates the locking body 11 allows, the profile 10 can only in one rotational position in the groove 12 occur. 6, this is not the case possible.
  • the dovetail or hammer head profile stands transverse to the inlet cross section in the groove 12. A rotation of the Cylinder core 2 is already after a small angle of rotation blocked.
  • a projection 15 of the profile 10 overlaps a contact surface 16 in the recess 14, so that a push back about through an attempt to vibrate the locking body to move is not possible.
  • This lock can also between the shaft of the locking body 11 and the cylinder housing 1 may be provided. Only after turning the locking body 11 from the position according to FIG. 6 into the position according to FIG. 8 is this lock released and the locking body 11 can with its narrow profile side in the groove 12 to the left and to penetrate right. The profiled section of the locking body snaps out of the lock against one by this twisting vertical movement. In Fig. 8 this is locking (Projection 15, contact surface 16) not shown again.
  • the electromechanical described above is Locking generally in addition to mechanical Tumblers included in a locking cylinder.
  • On Key that locks such a locking cylinder can have a correspondingly toothed key bit and also carries a code transmitter, e.g. as a handle on the Key chalk, when approaching the lock cylinder or triggered by plugging in, sends out a code signal.
  • a code transmitter e.g. as a handle on the Key chalk
  • the rotary drive 3 At the door, e.g. in a pusher plate or at best even in the lock cylinder itself, there is a receiver circuit, which receives the code signal as an actual signal and with the or a plurality of permissible target codes.
  • the rotary drive 3 in Meaning of turning the locking body 5 or 11 in the longitudinal position of its profile 10, so acted upon in the release position.
  • the teeth of the Key beard is correct, i.e. the serration the shared, spring-loaded tumbler pins (core and housing pins) Brings division, the cylinder core 2 in the cylinder housing 1st turned and a mortise lock or the like Lock bolts are withdrawn.
  • the mechanical tumblers shift in the locking cylinder in the locked position, and the rotary drive 3 rotates the locking body 5 and 11 with its head Profile 10 across (or at an angle) to groove 6 or 12. If then someone just wants to lock with a mechanical key, then the mechanical tumblers can probably be unlocked, but not the electronics with the electromechanical Lock. But if, according to FIGS.
  • the bolts 8, 9 a include correspondingly large angles (e.g. 30 °), then can the changing of a mortise lock can be operated.
  • the latch In order to the latch can be pulled back on a door with a knob.
  • the lock can be locked or unlocked with the bolt only the holder of a key with an electronic code transmitter. This makes it possible to build an office e.g. to lock at night that nobody has access and employees during the day, who only have a purely mechanical key, access to enable. This is part of a locking system Possibility extremely advantageous, since certain areas without additional lock complemented by electronic or electromechanical Measures according to the invention can be secured.
