Definitions

  • the invention relates to a lock according to the preamble of claim 1. Furthermore, the invention relates to a method for recoding a lock with tumblers according to at least claim 1, wherein the tumblers are brought in a lock case by means of a key about a rotation axis in a predetermined position be moved and by means of a rotatable by the key actuator a bolt in the lock case, the key is removable only in one position and positionable in several positions.
  • Locks of the generic type are already known. By means of a key having a key bit with different depths incisions, thin plates, preferably metal plates, which are referred to as tumblers, pivoted to different degrees by a predetermined pivot point. Each of the tumblers is provided with at least one recess into which engages at least a portion of a locking bolt. Locks of the generic type are equipped with several such tumblers so that they must be pivoted as described above with a corresponding key so as to align the recesses so that the locking bar or parts of the locking bar can engage in this now uniform recess. For example, to recode such a lock to another key if the key is lost, other tumblers or existing ones must be used in a different order.
  • the fence blades are provided with a toothing, which are fixed in position via a spring-loaded coding device.
  • a Umkodierzapfen is actuated in the lock case and pressed axially inward to achieve that during the rotation of the key, ie during the closing process, the coding no longer engages the toothing of the fence slats and thus their fixation is repealed.
  • the recoding pin remains in this depressed position as it is held over a pin.
  • the tumblers are raised during the closing process by the key teeth and take a new position.
  • the fence slats are moved transversely to the bolt, because the legs of the fence slats are still in contact with the tumblers.
  • the recoding pin is also released again and automatically moves from its depressed position into its starting position, since it is spring-loaded.
  • the recoding thus takes place in that the position of the legs, which engage in the tumblers, is changed relative to the bolt.
  • Such recombinations are relatively expensive, since a plurality of parts are used to achieve the desired recoding.
  • a generic lock is also known from DE-PS 565 027 known.
  • This prior art lock consists of a lock case in which two sets of tumblers are arranged, which tumblers are adjustable via two keys to release a lock in the lock box arranged latch in the direction of displacement.
  • the tumblers which are movable by means of two keys, have different designs and are oriented oppositely, so that two locking elements of the bolt can only be pushed into corresponding recesses of the tumblers if the tumblers are correspondingly provided with their recesses by the position of the applicable key.
  • the tumblers can be adjusted depending on the key.
  • an axis of rotation is provided which is adjustable from outside the lock case.
  • the axis of rotation is formed by a nose on a rotary member, wherein the nose engage in corresponding teeth of the tumblers.
  • FR-A-2 535 772 discloses a lock which has different tumblers which are oppositely arranged in a lock case, so that also in this lock two keys are necessary for actuation. A displacement of the tumblers relative to the axis of rotation is not provided here.
  • the invention has the object of developing a preferably alssperrgebuttes lock so that the recoding is easier to handle and minimizes reached the inserts or simplified to reduce the cost.
  • the rotary member is positively connected to a locking element which is equipped with a link which is acted upon by a guide element which is connected to the latch. This ensures that the lock can be adapted to a new key, without exchanging the tumblers. In a relative to the lock case different position of the tumblers in their zero position, it is by design excluded that all tumblers rest on the bolt. This is also kinematic reasons, since no curve over all adjustment positions of the tumblers forms a constant distance to the bolt. Although it is possible to iteratively establish an approximation curve and thus to minimize the distance difference, but there is always a difference.
  • an elastic element for example an elastomer profile
  • the tumblers are slightly displaceable in their longitudinal direction with respect to the direction of movement of the bolt. It is thus ensured that, in the case of an externally acting displacement force on the bolt, the tumblers which first come into contact with the bolt can dodge until the difference in length has been absorbed and all tumblers on the bolt come to rest.
  • a Aufsperr issued, in which just by said pressing the bolt against the tumblers by means of a wire is trying to pivot each tumbler in its unlocked position, thus effectively prevented because not only a tumbler rests on the bolt.
  • the nose fixes the tumblers in their fulcrum position.
  • the shape of the nose is designed so that it engages in the corresponding notches of the tumblers.
  • the tumblers are particularly identical in shape, so that no different tumblers must be installed in a predetermined order during assembly of the castle. This results on the one hand economic advantages in terms of keeping the tumblers and on the other hand simplified assembly, since the use of identical tumblers no detailed installation instructions must be given.
  • the identity of the tumblers extends in particular to the Tourkananl and the closing curve. Due to the convertibility of the tumblers by means of the rotary element in combination with a toothing the tumblers can be arranged even with identical design such that the necessary safety requirements are met in such a lock.
  • the notches in the tumblers are designed as a row of teeth.
  • the rotary member can be pivoted with a commercial screwdriver. But it is also an embodiment conceivable in which the rotary member is pivoted with a commercial hex key.
  • the locking element is equipped with a backdrop into which a guide element which is firmly connected to the latch, engages.
  • the scenery is designed so that pivoting is possible only in a predetermined position of the bolt.
  • the key which are designed for example as a dome and / or as an actuating element, wherein the dome engages in the tip of the key and the actuating element is in operative connection with the key.
  • the actuator By the actuator, the bolt is moved over a driver.
  • the tumblers are designed according to the training with beads that are designed differently in adjacent tumblers. This ensures that the tumblers are not flat to each other, but are spaced in each of their pivotal position. An elaborate deburring can thus be dispensed with.
  • each of the tumblers due to their shape design, loaded in each of their pivotal position with the same spring force.
  • An advantageous embodiment of the lock according to the invention provides that between the means for guiding the key and the tumblers a shielding is arranged, or that the tumblers are designed so that they are always acted upon by a same initial spring force.
  • an actuating element is provided for the articulation of the tumblers, or that the tumblers are acted upon transversely to its direction of rotation by an elastic element.
  • the shape of the tumblers is chosen so that they have the same distance from the spring seat to the axis of rotation of the key in each of its zero positions - closed position of the bolt and no action by key or actuator - and thus acted upon by a same initial spring force. It is thus also prevented a spying, since it can not be determined which tumbler is further pivoted; nor is it possible to use the restoring force of the spring to determine which end position is intended for the tumbler.
  • each of the tumblers is articulated at the same point and thus uniform contact traces be generated on all tumblers.
  • the actuator is equipped according to a development with only one slot-like opening, so that an all-round scanning is prevented. Through this slot-like opening and the beard of the key to deflect the tumblers.
  • the actuator is designed so that while using a example wrong key or a key-like object, although a rotation is possible, but the possible angle of rotation is limited. This also limits the possible scanning angle in the same way.
  • the actuating element has a driver, which allows the displacement of the bolt.
  • This driver is designed so that it shears in case of violence, for example, due to a predetermined breaking point, and thus prevents a displacement of the bolt is prevented.
  • the actuating element is made of thermoplastic material, so that it is destroyed by increased heat and thus also the displacement of the bolt is prevented.
  • the bolt has leg-like projections, which are designed with at least one nose. Through these projections, in conjunction with the lugs, it is ensured that always a portion of the bolt is in communication with the tumblers. The effect of the elastic element is thus supported.
  • a lock is shown schematically in perspective, showing a lock case 1 with inserted key 6. Parts of the lock case 1 are shown broken to make areal tumblers 3 recognizable that always press on springs 4 against an actuating element 5.
  • the bolt 2 is guided in the lock case 1 and can only be moved in its longitudinal axis when the tumblers 3 are brought via the key 6 in a predetermined position.

  • FIG. 3 shows the position of the lock during a recoding.
  • the actuator 5 and the key 6 have been rotated from the zero position a in a first detent position b and thus the tumblers 3 in response to the corresponding height of the key bit to a corresponding Angle has been pivoted about the axis of rotation 8.
  • Leg-like projections 12 of the bolt 2 engage in recesses 13 of the tumblers 3 a.
  • the rotary member 11 can be pivoted ⁇ by a predetermined angle, the nose 9, which is located on the rotary member 11, is disengaged from the teeth 10 of the tumblers 3.
  • the actuation of the rotary member 11 is possible from outside the lock case 1. In this position, the bolt 2, the pivoting of the rotary member 11 is made possible because of the design of a link, the locking element 7 is released.
  • the new key 6 ' is now rotated from the second position c in the first position b, wherein the tumblers 3 are moved relative to the rotary member 11. Due to the structural design of the actuating element 5 and the locking element 7, it is necessary to pivot the rotary member 11 by the angle ⁇ to its initial position to bring the nose 9 of the rotary member 11 with the teeth 10 into engagement before further rotation of the key 6 'is possible.
  • the axis of rotation 8 of each tumbler 3 is thus changed and has been recoded to the new key 6 '.
  • FIG. Key 6 and actuating element 5 lie on a common axis of rotation, wherein the actuating element 5 is fixed in the lock case 1.
