The retainers are adjustable in their position relatively to the rotary axis in the direction of their surface. Adjustment occurs at right-angles to the displacement direction of the bolt. For pivoting the retainers a key is provided. The rotary axis of the retainers is formed by a nose structure (9) on a rotary component (11). The retainers are identically formed and the rotary component is accessible and rotatable from the exterior of the lock box.

Description

The invention relates to a lock with tumblers in one flat lock case, with a bolt slidably arranged in the lock case is, the tumblers arranged pivotable about an axis of rotation are the tumblers in their position relative to the axis of rotation in the direction of their surface are adjustable, the adjustment being substantially perpendicular to the direction of displacement of the bolt and for pivoting the tumblers Key is provided. The invention further relates to a method for recoding a lock with tumblers, the tumblers in one Lock case by means of a key about an axis of rotation in a predetermined Be brought in position and by means of a rotatable by the key Actuator a bolt is moved in the lock case, and wherein the key can only be removed in one position and positioned in several positions is.

Locks of the generic type are already known. Using a key which has a key bit with incisions of different depths thin plates, preferably metal plates, referred to as tumblers are pivoted to different degrees around a predetermined pivot point. Each of the tumblers is provided with at least one recess in which at least engages part of a locking bolt. Locks of the generic type are equipped with several such tumblers, so that they are as described above have to be pivoted with a corresponding key, to align the recesses with each other so that the locking bar or Parts of the locking bolt can now engage in this uniform recess. Around for example, if the key is lost, such a lock on another To recode the keys, other tumblers or the existing ones must be used in a different order.

An already simplified solution is proposed in EP 0 663 497 A2; here describes a recodable lock that has several spring-loaded tumblers has, which are each pivotable about a pivot axis and provide openings at their ends remote from the pivot axis in order to hold a leg of a fence slat in it, so attached is that it can move across the direction of the lock bolt.

The fence slats are provided with teeth that are spring-loaded Coding device are fixed in their position. To do a recoding, we operated a recoding pin in the lock case and axially inwards pressed in order to ensure that when the key is turned, i.e. when Closing process, the coding device no longer in the teeth of the fence slats intervenes and thus their fixation is released.

The recoding pin remains in this pressed position because it has a Cone is held. After replacing the key with a new one The tumblers are the key to what is possible after a rotation of 180 ° raised by the key teeth during the closing process and take one new position. At the same time, the fence slats are moved across the transom, since the legs of the fence slats are still connected to the tumblers stand. By further turning the key, the recoding pin becomes again released and automatically comes out of its depressed position in its initial position, since it is spring-loaded.

The recoding is done by changing the position of the legs in the tumblers intervene, is changed relative to the bolt. Such recodings are relatively expensive because a plurality of parts are used to the to achieve the desired recoding.

A generic lock is also known from DE-PS 565 027. In this lock, the tumblers face away from the bolt End slot-like recesses in which a web engages. Different Coding can be done by a different engagement of the web be inserted into one of the recesses. For adjustment it is necessary to move the bridge within the lock case, creating a large Lock case is required.

On the basis of this prior art, the object of the invention is to develop a lock which is preferably unlocked in such a way that the recoding is easier to handle and the parts used are minimized or simplified in order to reduce the costs.

The solution to this problem provides that the axis of rotation of the tumblers is formed by a lug on a rotary element which, according to a feature further developing the invention, is accessible and rotatable from outside the lock case.

The rotating element is positively connected to a locking element, which is equipped with a backdrop that is made of a guide element that with the bolt is connected, is acted upon. This ensures that Lock on a new key can be adjusted without the tumblers exchange.

It is envisaged that the nose will fix the tumblers in their pivot position. The shape of the nose is designed so that it fits into the corresponding notches the interlocks intervenes.

The tumblers are of identical shape in particular, so that when mounting the lock no different tumblers in a predetermined Order must be installed. This results in an economic advantage with regard to the availability of the tumblers and on the other hand, simplification of assembly, since the use of identical Tumblers no detailed assembly instructions need to be given. The identity of the tumblers extends in particular to the Tourkananl and the closing curve. Due to the switchability of the tumblers using of the rotary element in combination with a toothing can the tumblers can also be arranged in such a way that the necessary security requirements for such a lock are met.

The notches in the tumblers are preferably designed as a row of teeth. Advantageously, the rotary element with a commercially available Screwdriver can be swiveled. However, an execution is also conceivable where the rotating element is pivoted with a commercially available hexagon wrench becomes.

The locking element is of particular importance; this is with a backdrop, in which a guide element that is fixed with the bolt connected, intervenes. The backdrop is designed so that it only pivots is possible in a predetermined position of the bolt.

As a further training, means for guiding the key are provided, which are designed for example as a mandrel and / or as an actuating element, wherein the mandrel engages the tip of the key and the actuator is actively connected to the key. Through the actuator the bolt moved over a driver.

To prevent them from getting caught, the tumblers are designed with beads executed that executed differently with neighboring tumblers are. This ensures that the tumblers do not lie flat on one another, but are spaced apart in each of their pivot positions. On an elaborate Deburring can thus be dispensed with.

Furthermore, due to their design, the tumblers are in each of their Swivel position loaded with the same spring force. The same applies to a defined one Deflection. That is, if, for example, the tumblers caused by their Setting in their zero position different positions relative to the lock case take, are deflected by actuation in the direction of rotation, each of the tumblers after an equally large deflection by an angle β the same amount of torque is required; an end position determination of the tumblers about their restoring force by the spring is therefore excluded. This applies independently of which setting position of the guard locking is assigned during coding has been.

With a different as described above relative to the lock case Due to the design, the position of the tumblers in their zero position is excluded. that all tumblers are on the bolt. This is also kinematic to justify, since there is no curve over all setting positions of the tumblers forms constant distance to the bolt. While it is possible to iteratively approximate a curve to set up and thus minimize the distance difference, it but there is always a difference. Therefore, an elastic element is provided, For example, to use an elastomer profile, so that the tumblers in their Longitudinal direction - in relation to the direction of movement of the bolt - slightly are movable. It is thus ensured that one acting from the outside Shifting force on the bolt the tumblers, the first with the Bars come into contact as far as they can dodge until the difference in length is caught and all tumblers come into contact with the bolt. On Unlocking attempt, in which just by pressing the bolt against the Tumblers using a wire is trying to get every single tumbler into theirs Swiveling the unlocked position is effectively prevented because it is not there is only one guard locking on the bolt.

An advantageous embodiment of the lock according to the invention provides that a shielding element between the means for guiding the key and the tumblers is arranged, or that the tumblers are designed so that they always have the same initial spring force. Alternatively it can be provided that an actuating element for articulating the tumblers is provided, or that the tumblers transverse to their direction of rotation an elastic element is applied.

These further developments ensure that the tumblers are scanned is prevented. Due to the shielding element, it is no longer possible for the individual Pivotal positions of the tumblers, for example with a thin one Wire to spy. Access to the tumblers is through the shielding element prevented, which in an advantageous manner with the lock case connected is.

The form of the tumblers is chosen so that they are in each of their zero positions - The bolt is in the closed position and no key is applied or actuator - the same distance from the spring rest to Have axis of rotation of the key and thus with the same initial spring force be charged. It also prevents spying, since it cannot be determined which tumbler is still pivoted; just as little it is possible to determine which one via the restoring force of the spring End position for the guard locking is determined. Also, for example, cannot a miniature lens can be used to determine which tumbler through which key cut is acted upon by an actuator that with the The key is in operative connection and is preferably equipped with a projection is, each of the tumblers is articulated at the same point and thus uniform contact traces are generated on all tumblers.

According to a further development, the actuating element has only one slot-like one Opening so that all-round scanning is prevented. By this slit-like opening also causes the beard of the key to deflect the tumblers. The actuator is designed so that when in use for example a wrong key or a key-like object although twisting is possible, the possible twisting angle is limited becomes. This also limits the possible scanning angle in the same way.

It is further provided that the actuating element has a driver, which enables the bolt to be moved. This driver is designed that in the event of violence, for example due to a predetermined breaking point, shears and thus prevents the bolt from moving. Preferably the actuator is made of thermoplastic, so that this is destroyed with increased heat and thus also that Moving the bolt is prevented.

Due to the design, it is excluded that all tumblers on the bolt issue. This is also to be justified kinematically, since there is no curve over all setting positions the tumblers forms a constant distance from the bolt.

The latch has leg-like projections, which are carried out with at least one nose are. These projections, in connection with the lugs, ensure that always an area of the bolt in connection with the tumblers stands. The effect of the elastic element is thus supported.

the lock according to Figures 6 and 7 in cross section.

In Figure 1, a lock is shown schematically in perspective, which shows a lock case 1 with the key 6 inserted. Subareas of the The lock case 1 is shown broken out to cover extensive tumblers 3 to make it recognizable that the springs 4 always against an actuating element 5 to press. The bolt 2 is guided in the lock case 1 and can only be in its Longitudinal axis are moved when the tumblers 3 into 6 via the key predetermined position are brought. Furthermore, there is an axis of rotation 8 in FIG. 1 the tumblers 3 can be seen, which is connected to a locking element 7.

Figure 2 shows an example of a tumbler 3 with a portion of the bolt 2 in its closed position. The key 6 can be removed in this position. On Rotating element 11 with an attached nose 9, about which the tumblers 3 pivot, stands in its starting position with a tooth of a row of teeth 10 in engagement. In this position of the bolt 2, the pivoting of the rotating element 11 prevented by a guide element, not shown, with the locking element 7 is connected, a pivoting of the rotary element 11 is prevented.

Figure 3 shows the position of the lock during a recoding.

The actuating element 5 and the key 6 are from the zero position a in one first locking position b has been rotated and thus the tumblers 3 in dependence the corresponding height of the key bit by a corresponding Angle has been pivoted about the axis of rotation 8. Leg-like projections 12 of the Bolts 2 engage in recesses 13 of the tumblers 3. In this position it is possible that the rotating element 11 by a predetermined angle α can be pivoted, the nose 9, which is on the rotary element 11th is out of engagement from the teeth 10 of the tumblers 3. The actuation of the rotating element 11 is from outside the lock case 1 possible. In this position of the bolt 2, the pivoting of the rotating element 11 enables the locking element because of the design of a backdrop 7 is released.

After pivoting the rotating member 11 is a further rotation of the Key 6 and the actuator 5 from the first position b in one second position c possible, which corresponds to the starting position a again Key 6 has thus been rotated 360 ° and can now be replaced by a second one Key 6 'are exchanged, which is in the bar version from first key 6 differs. Due to the backdrop in the locking element 7 in connection with the actuating element connected via the bolt 2 5 is an unwanted turning back of the key 6 on the position b prevented beyond. An uncontrolled adjustment of the tumblers 3 is thus locked out.

The new key 6 'is now from the second position c to the first position b rotated, the tumblers 3 are displaced relative to the rotary member 11. Due to the design of the actuator 5 and Locking element 7, it is necessary to rotate the rotating element 11 by the angle α to pivot into its starting position to the nose 9 of the rotary element 11 bring into engagement with the toothing 10 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 '.

The interplay of the individual parts is illustrated again in FIG. 4. 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. About a driver 16 the bolt 2 is moved. A guide element 17 on the latch 2 is in a setting of the locking element 7 in engagement. The locking element 7 is positively connected to the rotating element 11 on which the Nose 9 is located, which engages in the teeth 10 of the tumblers 3. The tumblers 3 are pivotable about this nose 9. The contact edge of the nose 9 forms thus the axis of rotation 8 of the tumblers 3. The rotating element 11 is also guided in the lock case 1 and is accessible from the outside.

FIG. 5 again illustrates the individual positions a - c of the key 6. Figure 5a shows the starting position a. The first position b is shown in FIG. 5b, this is after a predetermined rotation of the key 6 and Actuator 5 reached. The second position c is shown in FIG. 5c, this corresponds again to position a according to FIG. 5a. For easier finding Individual positions can be provided by means of a spring-loaded ball markings or be placed outside the castle.

With the lock according to the invention it is possible with a simple design to transcode from one key to another.

Another embodiment of the invention is shown in FIGS. 6 to 8. The perspective view of the lock according to Figure 6 shows the lock case 1 with the bolt 2 and inserted key 6. Through the partially broken The tumblers 3 and springs are shown in the upper area 4 recognizable, which act on the tumblers 3.

A longitudinal section through the lock case 1 is shown in FIG. The one in the closed position standing latch 2 has leg-like projections 12 which with Noses 21 are provided. These lugs 21 ensure an early investment of the Bolt 2 on the tumblers 3 and simulate in connection with tooth-like Projections 60 on the tumblers 3 engage the bolt 2.

The tumblers 3 can be pivoted about the axis of rotation 9 in the direction ω. By the action of the elastic element 14, the above described rest simulation supported. The tumbler 3 is designed so that the distance X is constant in each of its zero positions, regardless of the position taken Pivot around the axis of rotation 9. This also ensures that the initial spring force generated by the springs 4 for all zero positions is equal to.

Each tumbler 3 is designed with a bead 40 which is spaced apart each adjacent tumbler 3 guaranteed.

The key 6 used, which is guided by a key guide - here a mandrel 15 is in operative connection with the actuating element 5. The key beard can be brought into engagement with the tumblers 3 via the slot-like opening 18 are and deflects them differently due to the height of the beard. Due to the protrusion 50 attached to the actuating element 5, each tumbler 3 hinged in the same place; this creates uniform contact tracks generated, whereby a conclusion on the articulation point by the key bit is prevented.

If the key 6 is not inserted, as shown in FIG. 7, scanning would be the case conceivable by means of a wire. Access to the tumblers 3 is on the one hand by the design of the actuating element 5 with its slot-like Opening 18 and the projection 50 and on the other hand through the shielding element 25 so difficult that a reliable determination of the position of the guard locking 3 is not possible.

The sectional view in FIG. 8 illustrates the spacing of the tumblers 3 through the beads 40. Furthermore, the action on the tumblers 3 is through the elastic element 14 shown and the actuating element 5, which over the Driver 6 is connected to the bolt 2. The one designed as mandrel 15 Key guide element for the key 6 is anchored in the lock case 1.

With the measures shown you can unlock a lock be significantly increased.

Verdrehen des Schlüssels von einer Nullstellung a in eine erste Position b, wobei die Zuhaltungen 3 um eine Drehachse 8 verschwenkt werden und die beinartigen Vorsprünge 12 des Riegels 2 in die Aussparungen 13 der Zuhaltungen 3 eingreifen,

Verschwenken des Drehelementes 11 um einen Winkel α, wobei eine Nase 9 am Drehelement 11 aus der Aussparung 10 der Zuhaltungen 3 außer Eingriff gebracht wird, wobei das Drehelement 11 mit einem Verriegelungselement 7 verbunden ist, das über eine Kulisse durch ein Führungselement 17 mit dem Riegel 2 in Verbindung steht und das Verschwenken nur ermöglicht, wenn dieser das Verriegelungselement 7 frei gibt,

weiteres Verdrehen des Schlüssels 6 von der ersten Position b in eine zweite Position c; in dieser Position c werden sowohl der Riegel 2 als auch die Zuhaltungen 3 über den Mitnehmer 16 des Betätigungselementes 5 in ihrer Lage fixiert.

The method according to the invention for recoding a lock with spring-loaded tumblers has the following steps:

Turning the key from a zero position a to a first position b, the tumblers 3 being pivoted about an axis of rotation 8 and the leg-like projections 12 of the bolt 2 engaging in the recesses 13 of the tumblers 3,

Swiveling of the rotary element 11 by an angle α, a nose 9 on the rotary element 11 being disengaged from the recess 10 of the tumblers 3, the rotary element 11 being connected to a locking element 7, which is connected to the bolt via a link by a guide element 17 2 is connected and the pivoting is only possible if it releases the locking element 7,

further turning the key 6 from the first position b to a second position c; In this position c, both the bolt 2 and the tumblers 3 are fixed in their position via the driver 16 of the actuating element 5.

The next step in the process, namely

Removing the first key can be done safely. Then a second key inserted, which is in the beard version from the first Key differs. By turning the second key again The tumblers 3 from the second position c to the first position b shifted relative to the rotating element 11. Finally, the rotating element 11 in pivoted its starting position to the nose 9 of the rotary member 11 in the To bring recess 10 of the tumblers 3 into engagement.

The position of the pivot point of each tumbler 3 is thus changed, whereby recoding to match the new key is achieved.
