Description

The invention relates to a setting actuation device in a permutation lock with adjustment sensor, which at the beginning of the setting process in egg; brought a predetermined position and in this Z stood unchanged over a labyrinthine setting wi predetermined by the secret of the key is guided into an end position that enables the permutation lock to be opened, with the A! deviate from the predetermined adjustment path of the Einste! sensor not recognizable from the outside in its Au The initial position returns and thus prevents the opening of the permutation lock, whereby the Einste sensor than setting sensor unloaded in any position and rotatably mounted in its center of gravity excl is formed which on its adjustment path to throughc 'running adjustment levels according to code several times durc; running.

One such adjustment actuator is; the DT-PS 14 28 535 suggested that the express Actuation of the setting secret depending on the Wa! of the successive, required setting cases gen can require short adjustment paths. Also 1.

Known from OE-PS 2 33 435, a permutation closed with a contact switch actuatable by the setting handle for an alarm system to see ve, which can be brought into the shutdown position after the end of the code-compliant setting process.

The object of the invention is based on the Aufgar, a setting actuation device i to create a permutation lock with setting sensor d <presupposed type, which has an ei: clear, without accidentally running over a partial setting belonging to a key secret, G velvet setting enabled.

This object is achieved in that the relative movement between the setting sensor and a Labyrinth carrier via a gear mechanism that can be actuated with the pivot or the setting handle, e; Stepping mechanism or the like. Is adjustable. It is just a known fact that the code paintings. Setting a permutation lock easier ur can be done more safely when the Rastu!

genes can be felt exactly and clearly. That again: is best with the help of a setting that is not too short: possible. With a gear transmission according to the invention or also by ei Step-by-step switching mechanism can now use the effective adjustment path by selecting a corresponding! The translation can be sized as requested so that it is clear and without inadvertent practice driving a part setting part belonging to the code is adjustable. An advantageous further training best in the fact that the labyrinth designed setting wi arranged on the circumference of the labyrinth support and di adjustable from protruding lamella ends Lamellae is formed, which in radially extending,

recessed slots are inserted into the face of the labyrinth support.

This internal structure, i. H. by inserting the slats forming the positioning path into the The face of the labyrinth carrier results in a significantly smaller space requirement for the labyrinth path than with the Arrangement according to the proposal from the said DT-PS 14 28 535, in which the lamellae in axially on the Circumference of the rotating body distributed recessed slots are used. Also due to the new arrangement of the labyrinth path lamellas, the adjustment path is narrower and thus the adjustment stroke is smaller. That also leads to a compact design of the permutation lock. In addition, the setting level only the labyrinth lamellas are located and no locking levers or sensors, their position in the control the setting movement must be taken into account by appropriate locks through which the structure the permutation lock only becomes complicated.

For the permutation lock according to the invention, various embodiments are now possible, which are for certain areas of application are particularly advantageous. In one of these embodiments, the Trunnions or the adjustment handle via the gear drive and a push rod coupled to it connected, with which the labyrinth carrier is in adjustment connection, the labyrinth carrier on the Stationary adjustment sensor can be guided past. Such a permutation lock is mechanically relative simple. The sensitive, very thin setting sensor is arranged in a stationary manner and can therefore be attached in a protected location.

The labyrinth support that supports the adjustment path with the lamellae is overridden by the adjustment handle the gear mechanism rotated and pushed back and forth in the axial direction by means of a push rod, whereby the adjustment path can be guided past the stationary adjustment sensor in the sense of the key secret. This structure is particularly suitable for small permutation locks in cupboards, small flaps, Doors or in small boxes. For this purpose, the labyrinth support only needs to be small, so that its storage makes no difficulties for the axial movement. This storage is particularly in great large locks for large value containers, e.g. B. for safes in banks already more difficult.

For large permutation locks, a further embodiment is therefore particularly advantageous, the a division of the adjustment movement to be carried out along the labyrinth-like adjustment path between the setting probe and the labyrinth provides such that the setting probe moves in the axial direction and the labyrinth carrier is rotated.

This principle makes it easier to store the labyrinth carrier even for large permutation locks to solve. In a related embodiment, the adjusting device has an axially displaceable one Trunnion on, both of which is a pinion for engaging the ring gear that rotates the labyrinth carrier carries as well as having a push rod on its end face for axial movement of the setting sensor.

In this case, the setting sensor is then advantageously movably mounted on an annular spring that supports the setting sensor opposite to the labyrinth carrier is clamped on one side.

Another embodiment is characterized in that the adjusting device is known per se Way directly or indirectly with contacts of a microswitch of an alarm system in connection, the can be brought into the shut-off position after the end of the code-compliant setting process.

In the drawing are two exemplary embodiments shown. It shows

Fig. 1 shows the central longitudinal section through an exemplary embodiment with a fixed setting and rotary as well axially movable pivot pin,

Fig. La the gear drive between the pinion and the labyrinth carrier,

FIGS. 2, 3 and 4 show details of the adjustment parts in relation to one another from the exemplary embodiment according to FIG. 1 in perspective view,

F i g. 5 shows the central longitudinal section through an embodiment in which both the setting sensor and the labyrinth carriers are controllably arranged to one another,

6 shows the section.-1-ZJ according to FIG. 5,

7 shows a detail from the section AB of FIG. 6 with efer position of the setting sensor.

In Fig. 1, the lock housing 1 is installed in a door 2 shown here only in part. With the Lock housing is, finally, a cover 3 firmly connected. Inside the lock housing 1 is a Rotary body 4 is arranged, which has a cylindrical cavity 5.

This cavity is closed by a rotating part 6 with a protruding from the lock housing 1 Connecting pin 7, which is connected to a lock bolt, not shown here, in setting stands. A labyrinth carrier 8 is mounted in the cavity 5 formed by the rotating body 4 and rotating part 6. Finally, the setting handle 9 is arranged on the rotating body 4, with which, according to the code Adjustment of the locking mechanism the lock bolt is opened and later closed again. When the permutation lock is locked, the rotating body 4 and the rotating part 6 are spring-loaded here Locking pin 10 blocked with lock housing 1. The adjustment handle 9 and thus finally also the connecting pin 7 leading to the lock bolt, not shown, cannot then be rotated.

A pivot pin 11 is guided through the setting handle 9, the free end of which is led out of the setting handle. At its end protruding into the interior of the lock, it carries a pinion 12 and a thin push rod 13. The pinion 12 engages in a ring gear 14 which is arranged on the circumference of the labyrinth carrier 8. Further, a plurality of radially extending slots 15 are on the end face embedded inserted into a corresponding number of thin plates 16 and are mounted on a serving as a fulcrum ring spring 17, they α with a lamella end 16 protrude on the circumference of the labyrinth carrier. 8 With these protruding lamella ends 16 α , the labyrinthine adjustment path for the setting sensor 18 is marked by turning the lamellae 16 either to the right or to the left depending on the key secret selected, as can be seen in FIG. 2, for example.

The adjustment of the slats 16 is made with the help of a corresponding pin, which is through with Screws 19 closable bores 20 in the cover 3 is inserted.

For moving the labyrinth carrier 8 and unlocking it

of the permutation lock, the ring gear 14 is embedded in the labyrinth carrier 8 that the two ropes Toothing, an annular web remains. As a result, the labyrinth carrier 8 can not only be rotated via the pivot pin 11 with the aid of the pinion 12, but can also be pushed back and forth axially in the direction of the arrow, and it can thus be removed from the ends of the lamellae 16 (7 formed labyrinth on the exposed End of the setting sensor 18 are passed.

The setting sensor 18 is located in a slot of the rotating part 6, in such a way that it is in its starting position and after the correct setting according to the code, releases a push rod bore 21 in the rotating part 6, in the one hand is a push pin 22 for the locking pin 10 and from the other side before the Pinion 12 arranged in the end face of the pivot 11 small push rod 13 is inserted. At the end of the adjustment process, the pinion 12 has a Gap 23 in the left edge of the ring gear 14 opposite, as can be seen, for example, from the detail view according to FIG. Through this Gap, the pinion 12 is then advanced with the help of the pivot 11 and with it the push rod 13, to the extent that the locking pin 10 is above the push pin 22 against the force of a locking pin spring 24 pushed out of the rotating part 6 and thus the permutation lock is unlocked.

Then, by means of the adjustment handle 9, the unlocked rotating part 6 and the connecting pin 7 the lock bolt can be brought into the open position.

So now, even after an incorrect setting and thus in a still locked state, the thin one Push rod 13 not pushed through the setting sensor 18 blocking the push rod bore 21 by force can be, the push rod 13 is against the force of a compression spring 25, which is stronger than that Locking pin spring 24, mounted displaceably in a bore in the pivot pin 11.

A pin 26 limits this pushing movement of the push rod 13 to the front. There is also a backup on the other hand, it is provided that the pivot pin 11 can also be displaced when a lamella 16 is exactly in front of the setting sensor 18. This allows the lamellas to be coded according to their code Shifted position and thus the code destroyed and possibly also the slats and the adjustment sensor to be damaged. This lock consists, as can best be seen from Fig. 2, from one to the Trunnion 11 placed square 27, which is only in a very specific position by such a Square opening 28 in the bearing of the pivot 11 can be pushed.

From the schematic representations in FIGS. 3 and 4 it can be seen how the setting sensor 18 is set or through incorrect setting manipulations from its required to unlock the permutation lock Position or position can be brought.

At the beginning of the setting process, a rotation of the predetermined by the key mechanism causes the Labyrinth carrier 8 a relative to this stationarily arranged on the rotating part 6 bar spring 29, which previously on the peripheral area 8 "of the labyrinth carrier 8 rested, into a recess 30.

By having them previously at the lower end of the setting probe 18, by snapping it into the recess 30, it presses the positioning sensor 18 in its Ausgar shown in Fig. 4, for example.

position or position. As the labyrin carrier 8 continues to rotate in the Pleilrichtung, the rod spring 29 is:

Start up on the circumferential surface 8 «again picked up

s and the adjustment sensor 18 is free. Runs through e:

incorrect setting handling on the setting path:

bordering end of the lamella 16 a towards the adjustment sensor, it turns this into the position shown in FIG. 3 drawn Lai In this position it then blocks, as in Fig. 1d.

ίο set, the push rod bore 21 and the lock can not be opened by further turning and sliding movements of the labyrinth carrier 8 mc. The setting sensor 18 must then ι next by a corresponding setting c; Labyrinth carrier 8 brought back its starting position according to Fig. 4 by the rod leather 29 and ei whole adjustment process must then be properly repeated. Since these locking and unlocking processes take place completely noiselessly, such a permutation lock cannot be listened to. A further exemplary embodiment is shown in FIGS.

With this structure, the labyrinth carrier η is rotated and the axial adjustment movements are carried out by c!

appropriately controlled setting sensors. In de lock housing 31, which has a locking cover. is locked is one with a locking handle. provided rotating part 34 is arranged. This turned part is connected to a rotating part 35, which a the lock housing 31 protruding pin t sits, which is in setting connection with the lock bolt not shown here. The rotating part 35; by a spring-loaded rotary bolt 37 in the locked state of the permutation lock with de Closure cover 32 and thereby with the lock housing 31 blocked.

Between the rotating part 34 and the rotating part 35 '■. the labyrinth carrier 38 is mounted, which carries a ring gear 39 on an Ent. At his that number

4c wreath opposite end face are slots let in, as can be seen from FIGS. 6 and 7. In these slots 40 lamellae 41 are inserted. which are pivotably arranged on an annular spring serving as a fulcrum.

The over the circumference of the labyrinth carrier 38 Herai standing lamellar ends 41 α of the lamellae 41 form the externally adjustable labyrinth-like egg adjustment path for the setting sensor 43. In the lock has 33 the setting handle 44 is embedded for the setting of the locking parts according to the key secret. It is connected to a pivot 45, which is mounted in the Schliesshar, has 33 and is longitudinally shifted in the direction of the arrow.

On the protruding into the lock housing En of the pivot 45, a pinion 46 is arranged, ei with the ring gear 39 of the labyrinth carrier 38 i engages. In the face of the pivot 45 a small push rod 47 let in, with which by moving the pivot 45 in the Pleilrichtung c Adjustment sensor 43 can be moved in the axial direction. Here, as in particular also from FIG. 6 uni It can be seen that the setting sensor 43 is arranged on a thin spring ring 48 which is screwed with a screw bolt 49 is attached to the rotating part 34. In the vicinity <setting sensor 43 and together with it is mitt a bracket 50, a right-angled Winkelclhcbel is mounted, one arm of which is at a stop 52 lies and the other arm with a strap fcdci

is in adjustment connection. In addition, an adjusting pin 54 acts on the angle lever 51 and is fastened at a certain point on the circumference of the labyrinth carrier 38, as shown in FIG. 7. From FIGS. 6 and 7 it can also be seen that the lamellae forming the labyrinth path with their protruding lamella ends 41a, which are made of resilient material, are slightly bent so that they remain in the respectively set position due to friction on the slit walls. Finally, in a designated slot of the labyrinth carrier is mounted a pawl 55 38 α at the edge 55 of the Einstellfühler 43 can engage with its lower end, if he has not been pressed by a misadjustment of his action position.

The pawl 55 then in turn presses on the rotary bolt 37 im blocking the permutation lock Meaning of a removal of this lock. Finally, the screw bolt 40 is also a spring-loaded one The pawl 56 is attached to the rotating part 34 and engages in the ring gear 39 of the labyrinth carrier 38 and thus defines the necessary switching steps.

Then, in this exemplary embodiment, the contacts 57 and 58 of an electrical switch are preferably also used a microswitch, arranged. These contacts are opened by the rotary bolt 37 or closed. As an additional fuse, they belong to the circuit of one not shown here Alarm system, and should have the effect that when the permutation lock is opened correctly, the The alarm system is switched off.

The embodiment of the new permutation lock according to FIG. 5, 6, and 7 now work as follows.

It is initially assumed that the permutation lock is in the locked state, as shown in FIG. The rotary latch 37 is located while, by pressure of the bow spring 37 a, in the locking position shown, in which he has the the locking bolt connectable rotary part 36 with the lock housing 31, blocked.

Before starting the code-compliant setting process, which is required for unlocking, the setting sensor 43 brought into its starting or action position belonging to the setting according to the code will.

This position or position must then be maintained until the end of the entire setting process and It remains the same even if no key secret deviating from the selected key secret, i. H. so wrong adjustment handling was made.

The first setting manipulation with which the setting probe 43 is brought into its action position is

a rotation of the adjustment handle 44, in the embodiment shown here, clockwise from the lock handle 33. To this end, FIG. 7 must then be considered. During this rotary movement, the labyrinth carrier 38 rotates in the direction of the arrow. The adjusting pin 54 runs towards the lower arm of the spring-loaded angle lever 51 and presses it to the right against the force of the bow spring 53 (see arrow). As a result, the other lever arm lifts from its stop 52 and presses against the adjacent wing of the setting sensor 43 and moves the setting sensor in the direction of the arrow from the so-called unloaded position shown in broken lines into the solid drawn initial or action position. During this adjustment process, the adjusting pin 54 passes under the short arm of the angle lever 51, which is then pushed back into its starting position by the bow spring 53. In the excellent position, the setting sensor 43 must now remain until the end of the setting according to the key secret, so that it can then be pressed later by advancing the pivot 45 by means of the setting handle 44 against the edge 55 a of the pawl 55, which in the drawing according to F i g. 5 is still at the bottom, but when the setting process is complete, the setting sensor 43 is opposite.

By pressing against its edge 55 α , the pawl 55 is then pivoted about its pivot point 55 b against the lower edge of the rotating bolt 37 and pushes it out of the recess 35 a of the rotating part 35, whereby the permutation lock is unlocked, so that a with the rotating part 36 connectable locking bolt can be opened by means of the lock handle 33.

As in the exemplary embodiment according to FIG. 1 and in particular from the illustration in FIG is seen, the labyrinth-like adjustment path is also in the embodiment of FIG. 5 through the over the periphery of the labyrinth carrier 38 protruding lamella ends 41a of the lamellae 41 is formed. Also these slats are from the outside through holes not shown here by means of a pin in the Can be adjusted in the sense of a new key secret. Through this, without dismantling the permutation lock Changing the key secret, which can be set from the outside at any time, is one of the security features useful, frequent code changes possible.

By installing contacts of an electrical switch, for example in the manner as shown in FIG. 5 is shown, the rotary bolt 37 shown is in a simple manner as a setting secret-dependent alarm switch used.
