Definitions

  • the invention relates to a method and a device for locking and unlocking a locking device, in particular a locking device with a by a key-operated locking cylinder, which comprises a fixed, hollow cylinder housing with a hollow inner cylinder rotatable therein and rotatable disc tumblers and a closing means arranged thereon at the end .
  • Such a locking device is known from DE 34 21 754 C2.
  • a locking device of this type for example, the locking cylinder with its hollow inner cylinder and the disc tumblers is inserted into a blind hole in a housing.
  • the cylinder lock has a rotatably mounted hollow cylinder and in it a multiplicity of disc tumblers which are rotatably supported to a limited extent and can be rotated with a key.
  • Axially effective spring washers are arranged between the disc tumblers.
  • a cylindrical locking rod is arranged as the locking means.
  • the spring washers arranged between the tumbler disks each have one Central cylindrical perforation, which is so large that the corresponding key can be passed through without contact.
  • the object of the invention is to provide a method and a device which improve the locking and unlocking of a locking device, in particular with regard to handling and security.
  • the functional and operational safety are increased by the coding of the individual steps for locking and unlocking a locking device, which is predetermined according to the invention.
  • an intentional and unintentional rotation of the disc tumblers relative to one another is impossible, for example, it cannot be brought about by vibrations or the like, or by a key that is not fully inserted, or by wires or the like inserted into the keyhole will.
  • To actuate the locking device it is necessary that the key is first fully inserted into the insertion channel, which is formed by the corresponding perforations in the disc tumblers.
  • the second locking means by means of which the inner cylinder with the cylinder housing was previously locked against relative rotation, is only unlocked when the key is fully inserted.
  • the third locking means is then unlocked by turning the key slightly by a few degrees in the prescribed actuation direction, so that the disc tumblers can be rotated relative to the inner cylinder.
  • the disk tumblers can then be rotated into the desired position by means of the key, in which the release position of the first locking means is reached.
  • the locking means is then rotated by means of the key, so that the correspondingly equipped lock is adjusted to the open position.
  • the lock is closed, the key is turned in the opposite direction, the locking means being moved into the locking position in the opposite order.
  • the first locking means is preferably designed as a locking rod in a conventional design, as is known for example from the generic document.
  • the second locking means is preferably a double-acting slide bolt which is acted upon by locking springs and which, for example, is displaced into the unlocking position against spring force by the tip of the inserted key.
  • the third locking means can also be a cylindrical rod, pins, balls or rollers. It is also possible to arrange a plurality of balls arranged in a row with respect to one another, which then effectively represent a rod-shaped locking means.
  • the locking device essentially consists of a cylinder lock with key 1, which comprises a fixed hollow cylinder housing 2 with a hollow inner cylinder 3 rotatably arranged therein and disc tumblers 4 which can be rotated to a limited extent therein, and a locking means 5 arranged on the end of the inner cylinder 3 and rotatable by means of the key 1 . Furthermore, a first locking means 6 in the form of a cylindrical rod is provided, which locks the rotary movement of the closing means 5 relative to the cylinder housing 2 in a position mounted in the joint between the cylinder housing 2 and the inner cylinder 3.
  • the disc tumblers 4 are provided with circumferential recesses 7 arranged in such a way that the tumbler discs 4 are formed by combination surfaces 8 formed on the appropriate key 1.
  • Rotation of the inserted key 1 can be rotated into a release position, in which the first locking means 6 enters the circumferential recesses 7 of the disc tumblers 4, which are aligned with one another, and releases the inner cylinder 3 and the locking means 5 connected to it.
  • a second locking means 9 is provided, by means of which the inner cylinder 3 can be locked against relative rotation with the cylinder housing 2 and which can only be adjusted into the release position by the fully inserted key 1, in which the inner cylinder 3 can be rotated relative to the cylinder housing 2 .
  • a third locking means 10 is provided, for example in the form of a cylindrical rod, by means of which the disc tumblers 4 with the inner cylinder 3 can be locked against relative rotation, the third locking means 10 being able to be moved into a release position by turning the key 1 when the second locking means 9 is unlocked, in which the disc tumblers 4 are rotatable relative to the inner cylinder and, when the key 1 is rotated in the same direction, maintains the release position up to and including the position in which the release position of the first locking means 6 is reached.
  • the second locking means 9 is in the embodiment by two at the end of the key insertion channel beyond Disc tumblers 4 arranged slide bolts are formed, which are displaceable transversely to the insertion direction of the key 1 by the tip of the key 1 from the locked position into the release position.
  • the second locking means 9 is adjustable against the action of closing springs 11 in the release position.
  • the third locking means 10 consists of a rod-shaped locking body which is arranged radially and axially immovably in an axial recess 12 of the inner cylinder 3, the disc tumblers 4 in the closed position of the device having circumferential recesses 13 arranged in axial alignment with one another, into which the locking bodies ( 10) engage with part of their cross-section and rest with their area opposite the circumferential recesses 13 on the inner jacket of the cylinder housing 2.
  • a recessed (radially widened) recess directly next to the support areas 14 of the inner casing of the cylinder housing 2.
  • circumferential region 15 which extends over an angle of rotation of approximately 90 °.
  • the locking means is forced into this radially outward-widening region 15, provided that the disc tumblers 4 together with the inner cylinder 3 are rotated further by a few degrees, so that the locking means (10) then no longer sits in the peripheral recess 13 of the disc tumblers, but releases them.
  • the recess 15 is so long in the circumferential direction that the locking means 10 remains unobstructed over the entire rotational path of the disc tumblers 4 in the free space 15, so that it does not enter the joint between the disc tumblers 4 and the inner cylinder 3.
  • the first locking means 6 has, in the locking position in the circumferential direction of rotation of the inner cylinder 3, a play of movement, in the exemplary embodiment a play of movement on the cylinder housing 2, formed by a correspondingly wide axial recess 16, the play of movement being equal to or slightly greater than the path of the disc tumblers 4 the locked position in the release position of the third locking means 10 corresponds.
  • the function of the first and third locking means is explained using the sequence of figures in FIGS. 4 to 7.
  • the blocking position of both blocking means is shown in FIG.
  • an element of the second locking means 9 can also be seen.
  • the third locking means 10 is in this position in the longitudinal slot 12 of the hollow cylinder 3 and sits with a part of its circumference in the peripheral recess 13 of the disc tumbler 4. Radially outside is a portion 14 of the cylindrical bore of the cylinder housing 2, so that the locking means 10th cannot be pushed radially outwards.
  • the first locking means 6 engages in an axial slot 19 of the hollow inner cylinder 3 and protrudes beyond the outer alignment of the inner cylinder 3 into the corresponding recess 16 of the bore of the cylinder housing 2. In this position, the second locking means 9 is engaged, so that the inner cylinder 3 is held non-rotatably relative to the cylinder housing 2. A rotation of the disc tumbler 4 by means of a key or also by means of a wire or the like is not possible in this position.
  • the radially outwardly projecting area of the locking means 10 does not hinder this movement, since the recess 15 is formed over a corresponding circumferential area of the bore in the cylinder housing 2.
  • the circumferential recess 7 of the disc tumbler 4 is located in the region of the blocking means 6, which previously migrated in the radially enlarged recess 16 by such an amount in the circumferential direction according to the sequence of figures in FIGS. 4 and 5 which corresponds to the movement of the disc tumbler 4 and the inner cylinder 3 from the locked position into the release position with respect to the locking means 10.
  • the locking means 6 can then drop inwards into the corresponding recess 7, as is also shown in FIG. 7, so that all the disc tumblers 4 are by means of the corresponding key can be rotated and at the same time the inner cylinder 3 including the locking part 5 is rotated, in the example by approximately 90 °.
  • FIGS. 8 and 9 show the second locking means 9 in the locking position (FIG. 8) and in the unlocking position (FIG. 9).
  • the ends 21 of the locking means 9 designed in the manner of a double slide bolt engage in corresponding recesses 22 in the cylinder housing 2, so that the inner cylinder 3 is held non-rotatably. Only when the key is inserted are the locking ends 21 moved against the force of the closing springs 11 into a retracted position, in which they lie behind the circumferential alignment of the inner cylinder 3, so that the latter can be rotated relative to the cylinder housing 2.
  • FIG. 17 The blocking position is shown in FIG.
  • an element of the second locking means 9 can be seen in each case.
  • the first locking means 6 engages in an axial slot 19 of the hollow inner cylinder 3 and projects above both the outer alignment of the inner cylinder 3 into the corresponding recess 16 of the bore of the cylinder housing 2, as well as into a circumferential recess 7 of the disc tumblers 4.
  • the dimensions are such that the locking means 6 cannot be pushed radially out of this position.
  • the second locking means 9 is in the engaged position, so that the inner cylinder 3 is held non-rotatably relative to the cylinder housing 2. Rotation of the disk tumblers 4 by means of a key or also by means of a wire or by means of vibration is not possible in this position.
  • the disc tumblers 4 can now be rotated relative to the inner cylinder 3, the rotational movement of the inner cylinder 3 being blocked by the active engagement of the locking means 6 between the inner cylinder 3 and the cylinder housing 2.
  • a further circumferential recess 24 reaches the area of the locking means 6, as can be seen from FIG.
  • This circumferential recess 24 of the disc tumblers 4 is expanded radially inward relative to the other circumferential recess 7, so that the locking means 6 can be displaced radially inward so that it is in the circumferential recess 24 and in the slot 19 of the Inner cylinder is located, but does not protrude beyond the outer alignment of the inner cylinder.
  • a further further rotation of the disc tumblers 4 including the inner cylinder 3 together with the locking part 5 can take place by means of the key 1 until the locking part is adjusted into the release position.
  • the invention is not limited to the exemplary embodiment, but is variable in many ways within the scope of the disclosure.
