can.

Furthermore, it can be provided that a holding surface 68 is formed on the latch slide 62, wherein in the ejection position 64 of the latch slide 62 the locking tongue 30 of the latch 17 can rest on the holding surface 68, whereby the latch 17 can be held in its unlocking position 19. In particular

It may be that the cover housing 80 is designed as an injection-molded part.

The function of the first embodiment of the locking device 9 is

now described using Fig. 3 to 5.

In a starting position, as shown in Fig. 3, the bolt 17 can be in its unlocking position 19. The latch slide 62 can be in its ejection position 64, whereby it is held in its ejection position 64 by the latch slide spring 66. The latch tongue 30 of the bolt 17 can rest on the holding surface 68 of the latch slide 62, whereby the bolt 17 can be held in its unlocking position 19. The pivot lever arrangement 37 can be in its release position 39, whereby the pivot lever pin 40 is in the first latch leg recess 56 or in the second latch leg recess 58.

The recess 57 can be accommodated in the joint leg.

Due to the spring force of the actuator return spring 55, the pivot lever arrangement 37 can be pushed or pre-tensioned into its blocking position 38, whereby, however, the

Pivoting lever pin 40 on a first front wall surface 81 of the first locking

leg recess 56 or a second front wall surface 82 of the second locking leg recess 57. This form-fitting connection can prevent the pivot lever arrangement 37 from moving into the release position 39 and, when the electric actuator 54 is not energized, this position can be held stable as shown in Fig. 3.

become.

When the lock tongue 8 is inserted, it can come into contact with the contact surface 63 of the latch slide 62, whereby the latter is moved from its ejection position 64 towards its retraction position 65. Due to this displacement of the latch slide 62, the retaining surface 68 can come out of engagement with the latch tongue 30, whereby the latch 17 can be moved into the locking position.

position 18 is released.

When the latch slide 62 is moved further in the direction of its retracted position 65, the further contact surface 67 of the latch slide 62 can come into contact with the first lever part contact surface 45 of the first lever part 43, whereby the pivot lever 41 can be pivoted about the pivot lever pin 40. The second lever part contact surface 46 of the second lever part 44 can come into contact with the pivot lever contact surface 33 of the bolt 17, whereby the bolt 17 is moved from its unlocked position 19 into its locked position 18. The bolt tongue 30 can be pushed into the bolt tongue recess.

mation 31 of the lock tongue 8.

If the latch 17 is displaced sufficiently far in the direction of its locking position 18 and the pivot lever pin 40 is located outside the first latch leg recess 56 or the second latch leg recess 57, the pivot lever arrangement 37 can be displaced into its blocking position 38 by the spring force of the actuator return spring 55. In this case, the pivot lever pin 40 can be arranged above the first contact surface 23 or the first contact surface 23 can rest against the pivot lever pin 40. This can ensure that the latch 17 is secured against displacement into the

Unlocking position 19 is secured. This position of the locking device

A2022/87025-AT2

The locking device 9, as shown in Fig. 4, can also be held stable with a currentless electric actuator 54, whereby the locking tongue 30 can be positively received in the locking tongue recess 31 of the lock tongue 8

and thus removal of the lock tongue 8 can be blocked.

To release the lock tongue 8, the electric actuator 54 can be energized, whereby the pivot lever arrangement 37 can be moved from its blocking position 38 into its release position 39 against the spring force of the actuator return spring 55. As a result, the pivot lever pin 40 can be moved from its blocking position above the first contact surface 23 or the second contact surface 24 into the first locking leg recess 56 or into the second locking leg recess 57, whereby the locking bolt 17 can be moved from the

Locking position 18 is released into unlocking position 19.

If the pivoting lever pin 40 is moved further in the direction of the release position 39, the pivoting lever pin 40 can come into contact with the first lifting surface 58 or the second lifting surface 60. Due to the angle 59, if the pivoting lever pin 40 is moved further in the direction of the release position 39, the bolt 17 can be moved from its locking position 18 to its unlocking position 19. As soon as the bolt tongue 30 is out of engagement with the lock tongue 8, in particular outside the bolt tongue recess 31, the lock tongue 8 is ejected by means of the latch slide 62 by the spring force of the latch slide spring 66, whereby the latch slide 62 moves from its retracted position 65 into

its ejection position 64.

When the latch slide 62 is completely moved into the ejection position 64, the locking tongue 30 can rest on the holding surface 68. This allows the latch 17 to be secured in its unlocking position 19. If the electrical actuator 54 is still energized, the pivot lever pin 40 can continue to rest on the first lifting surface 58 or the second lifting surface 60. If the electrical actuator 54 is now interrupted, the pivot lever arrangement 37 can move due to the spring force of the actuator reset spring.

the 55 in the area of the release position 39 slightly so that the

A2022/87025-AT2

Pivoting lever pin 40 no longer rests against the first lifting surface 58 or the second lifting surface 60, but comes to rest against the first front wall surface 81 or the second front wall surface 82 of the first locking leg recess 56 or the second locking leg recess 57. This can now be a stable state again, as shown in connection with Fig. 3 at the beginning

of the procedure was described.

In order to be able to check that the lock tongue 8 is correctly inserted into the locking device 9, it can be provided that the position of the latch slide 62 is detected by means of the sensor 74. The duration of the current supply to the electrical actuator 54 can be coupled to the current position of the latch slide 62. In particular, it can be provided that the current supply to the electrical actuator 54 is interrupted when the latch slide 62 is in its

in a retreat position 65.

An improper displacement of the latch slide 62 from its ejection position 64 into its retraction position 65 by an object other than the lock tongue 8 can be detected by the fact that the latch slide 62 can indeed be moved into the retraction position 65 and the bolt 17 is also moved into its locking position 18, but after removing the object used to move the latch slide 62, the latch slide 62 is moved in the direction of the ejection position 64 due to the spring force of the latch slide spring 66 until the contact surface 63 of the latch slide 62 rests against the bolt tongue 30. This unexpected position can thus be detected by means of the sensor 74 and the electrical actuator 54 can be energized in order to move the bolt 17 back into its unlocking position 19.

to transfer.

Improper closing of the locking device 9 with an object other than the lock tongue 8 can also be prevented by mechanical measures.

men can be achieved.

A2022/87025-AT2

Such a mechanical measure is described in the further embodiment of the locking device 9, which is shown in Fig. 6 and 7. In Fig. 6, the same reference numerals are used for the same parts.

chen or component designations as in the previous Fig. 3 are used. And in Fig. 7, the same reference numerals or component designations are used for the same parts as in the previous Fig. 4. To avoid unnecessary repetition, reference is made to the detailed description in the

previous Figures 2 to 5 are mentioned or referred to.

As can be seen from Fig. 6, a pin 83 can be formed which can be arranged in the latch slide 62. The pin 83 can be arranged in the latch slide 62 so that it can move between a blocking position 84 and a retracting position 85. If the latch slide 62 is moved backwards with an object other than the lock tongue 8, the pin 83 can be in its blocking position 84, as can be seen in Fig. 6, provided that this object is not pressed against the latch slide 62 in the area of the pin 83 in order to simultaneously press the pin 83. This can prevent the bolt 17 from moving into its locking position 18, since the bolt tongue 30 can rest against the pin 83. Since the pin 83 is arranged centrally in the latch slide 62, the pin 83 can be moved into its retracted position 85 with a centrally acting object, but the centrally acting object would prevent the bolt 17 from being moved into the locking position.

tion 18 block.

Only when inserting the lock tongue 8, which has the latch tongue recess 31 and has the shape characteristic of the lock tongue 8, can it be achieved that in such an embodiment the pin 83 can be moved accordingly into the retracted position 85 and the latch

17 into the locking position 18.

A further embodiment of the locking device 9 will now be described with reference to Fig. 8 and 9. The same reference numerals or component designations are used for the same parts as in the previous

Descriptions of Fig. 2 to 4 are used.

A2022/87025-AT2

Fig. 8 shows the locking device 9 in a locking position 18 of the bolt 17 in perspective. In this closed position of the locking device 9, in which the lock tongue 8 is held by the bolt tongue 30 of the bolt 17, the pivot lever arrangement 37 is also in its blocking position 38. This means that the second lever part 44 of the pivot lever arrangement 37 prevents the bolt tongue 30 from being lifted or

Swing the latch 17 up into the unlocking position 19.

Fig. 9 shows the locking device 9 according to Fig. 8 in a perspective half-section view. The positions of the bolt 17 and the latch slide 62 interacting with it, as well as the pivot lever arrangement 37 with the electrical actuator 54, correspond to an open locking device 9 in which the lock tongue 8 is released. This open state of the locking device 9 is achieved by the pivot lever arrangement 37 with the pivot lever pin 40 being moved from the blocking position 38 (Fig. 8) to the release position 39 under the action of the electrical actuator 54. This displacement of the pivot lever arrangement 37 with the pivot lever pin 40 simultaneously enables the pivot lever pin 40 to be pressed against the inclined first lifting surface 58 of the first bolt leg recess 56, whereby the bolt tongue 30 of the bolt 17 is raised. This finally enables the latch slide 62 to be moved from its retracted position 65 into the ejected position 64 by the latch slide spring 66, whereby the lock tongue 8 is simultaneously pushed out of the locking device 9.

is pushed.

In the locking device 9 according to this embodiment, the electric actuator 54 comprises not only a magnetic coil 86 but also a permanent magnet 87 as part of a common magnetic circuit. This contains not only a yoke 88 but also an armature 89 which is coupled to the pivoting lever pin 40 for generating the adjustment movement of the actuator 54. The permanent magnet 87 makes it possible for the armature 89 to remain in the position it is in once the release position 39 has been reached, even when the actuator 54 or its

Solenoid coil 86 is held in the release position 39. This can be

A2022/87025-AT2

It can be achieved that the holding force of the permanent magnet 87 in the fully retracted position of the armature 89 (corresponding to the release position 39) is greater than the restoring force of the actuator return spring 55. The permanent magnet 87 in the magnetic circuit of the actuator 54 thus ensures that the release position 39 is maintained even when the magnetic coil 86 is de-energized. To release the corresponding stroke end position of the armature 89 or the electric actuator 54, it is possible to use a short current pulse through the magnetic coil 86 with a magnetic field that weakens or reverses the magnetic field of the permanent magnet 87 to reduce the restraining effect of the permanent magnet 87.

to temporarily cancel.

By providing the permanent magnet 87 in the electrical actuator 54, it can be ensured that the locking device 9 cannot be closed in the event of a defect, a power failure or generally in the idle state. In the case of parcel machines 1 with a correspondingly large compartment 2, a child safety lock function can be provided by a locking device 9 according to this embodiment, i.e. with a permanent magnet 87 in the electrical actuator 54.

can be produced.

An erroneous closing of the locking device 9 or an unintentional locking of, for example, a small child who has hidden in the compartment 2 is thus reliably prevented. The locking device 9 is only made ready for locking when an impending and intended closing is detected by the control electronics provided in the computer 75. To this end, the control electronics of the computer 75 trigger a current flow in the magnetic coil 86 that counteracts the magnetic field of the permanent magnet 87. This ensures that, under the effect of the actuator return spring 55, the armature 89 is displaced so far that the spring force of the actuator return spring 55 exceeds the opposing holding force of the permanent magnet 87 to such an extent that the spring force of the actuator return spring 55 acts on the pivot lever arrangement 37 in such a way that it is forced into the blocking position 38. If the latch slide 62 is now closed when the

Door or the locking element of the compartment 2 by the lock tongue 8 from the

A2022/87025-AT2

ejection position 64 into the retraction position 65, the bolt 17 can finally be moved from the unlocking position 19 into the locking position 18

and the pivot lever arrangement 37 assumes the blocking position 38.

In an alternative embodiment of a child safety lock to the locking device 9 according to Fig. 8 and 9, the holding of the actuator 54 in the release position 39 of the pivot lever arrangement 37 can also be designed by a mechanical stepping gear or a tensioning mechanism. Such a mechanical stepping mechanism can be realized, for example, by providing a known tensioning mechanism of a pressure pin instead of the release fork 47 in the locking device 9 according to Fig. 3 and 4. Repeated, consecutive actuations of the electrical actuator 54 cause the pivot lever arrangement 37 to change successively between the release position 39 and the blocking position 38. This can also ensure that the locking device 9 cannot be closed or locked with the lock tongue 8 in the power-off state if the release position 39 remains securely upright after the compartment 2 has been opened.
