Description

Designation: Pivot bolt lock

The invention relates to a pivot bolt lock according to the preamble of claim 1. Pivot bolt locks with a swivel or rotary latch are well known. For example, in US 8,261, 586 B2, a pivot bolt lock is described. In this pivot bolt lock a pivot bolt is rotatably mounted on a bearing, said pivot bolt from its open position in which it is located completely within a housing can be pivoted through an opening in the housing in a closed position, in which case a locking element of the pivot bolt from the opening of the Housing protrudes.

So that this pivot bolt can not be unjustifiably pivoted by force from the outside, a plurality of teeth are provided for this purpose on the back of the pivot bolt, which teeth with corresponding teeth on the housing wall in the region

Opening through which the pivot bolt is pivoted out of the housing, correspond. These corresponding teeth serve to intermesh in an attempt to forcibly turn the pivot latch and thus prevent the pivot latch from rotating. Nevertheless, there is the possibility that with prolonged violent action on the pivot bolt, the locking effect can be overcome in this bolt lock, as occurring at the corresponding teeth wear.

Furthermore, acceleration effects can lead to the fact that this locking mechanism can be overcome and the locking bolt can be forcibly transferred from its closed position to its open position. Also, there is the problem in this pivot bolt lock that high precision must be placed on the locking mechanism in the form of the corresponding teeth castle components to ensure just under the conditions of a series production high reliability and proper operation of the Schenkriegelschlosses. In order to ensure such high precision, but to go through a time-consuming and procedurally complex process, which is also associated with a high cost.

In addition, the mechanical effort for the drive of the blocking element is relatively high and the drive must be arranged by the limited spatial conditions in the middle of the castle. However, there is the problem that - if at all feasible - in the leading by this pivot bolt lock drive linkages, such as rotary keyboards, no adequate space for armor or no protection against manipulation.

Furthermore, from DE 10 2008 008 598 A1, a generic type pivot bolt lock is known. However, the local locking bow is formed as a sector plate, which can not ensure unauthorized pivoting of the pivot bolt in the case of external violence on the local pivot bolt alone due to their small dimensions and their unattached guide in the housing.

It is therefore an object of the invention to develop a pivot bolt lock according to the preamble of claim 1 such that both a procedural or manufacturing technically simple pivot bolt lock is provided in which a sufficient protection against manipulation is given, in particular against a violent attempt, the pivot bolt move its closed position to its open position, and there are sufficient opportunities for additional armor. This object is achieved by a pivot bolt lock with all features of claim 1. Advantageous embodiments of the invention can be found in the subclaims.

The pivot bolt lock according to the invention in this case has a housing in which a pivot bolt is rotatably supported by means of an adjusting device between an open position and a closed position, wherein the pivot bolt is fully received in the open position in the housing and in the closed position with a locking element through an opening protruding from the housing. According to the invention, it is now provided in the pivot bolt lock that the adjusting device has a spindle drive driving a spindle, wherein a threaded bush is arranged on the spindle, which is arranged in a locking arc rotatably mounted in the housing. The locking arc is thus pivotable between a locking position and a release position, wherein the locking bolt is connected to a lever which in the closed position of the pivot bolt and in the locking position of the locking arc in a Sper- recess of the pivot bolt engages and in an open position of the pivot bolt and a release position of the locking elbow is out of engagement with the Sperraussparung.

The inventive design of the pivot bolt lock, it is now possible borrowed form the locking lever very solid, especially as a high-strength steel part or the like, which can engage in the corresponding locking recess of the locking bolt. In this case, taking into account the massive pivot bolt, a very high blocking force absorption by the pivoting ratchet lock can be realized. In particular, the pivot bolt of the pivot bolt lock according to the invention thereby can not be pivoted in a simple manner by the action of force. This also contributes to the present invention to be used spindle drive, which is mechanically connected via the locking bow directly with the locking effect performing lever, since such spindle drives are also designed to be self-locking. In addition, can be excluded by the inventive design of the pivot bolt lock a rising of the lock during manipulation, especially in the field of vibration or acceleration excitations. In addition, the inventive design of the pivot bolt lock also makes it possible to place the drive motor with spindle drive at the edge region of the lock. This creates more space for armoring a lock bushing but also for the electronics assembly in the center of the housing of the pivot bolt lock.

According to a first advantageous embodiment of the invention, it is provided that the lever against the locking bow is pivotally arranged on this. This configuration of the invention makes it possible for the locking bow to be returned to its locking position by means of the spindle drive, while the lever remains in the position which it assumes in the open position of the pivoting bolt into which it locks in the locking recess of the pivoting bolt releases. This is particularly advantageous because the locking bow is already in its locked position can be seduced when the

Swing bar still remains in its open position. This makes it possible that after the transfer of the pivot bolt from its open position to its closed position, only the arranged on the locking bow lever must be pivoted so that it comes back into engagement with the Sperraussparung the pivot bolt to lock the invention To ensure the effect of the swing bolt lock even in the event of violence and in the event of acceleration and vibration forces. In particular, by means of the spindle drive, after the release of its release position within a predetermined time window, for example 3 seconds, the locking arc can thus be transferred again into its locking position. In this respect, the problem is also prevented that a transfer of the locking elbow into its locking position does not have to be performed separately, but is automated and thus the blocking function and the proper functioning of the pivot bolt lock according to the invention can be ensured.

Thus, the lever automatically moves from its relative to the locking arc pivoted position to its original starting position in which it is engaged with the Sperraussparung the pivot bolt, it is provided that the lever against the locking bolt against a restoring force is pivotally mounted on this. This restoring force between the lever and the locking bow is built upon transfer of the locking bow from its release position to its locking position, wherein the lever is then disengaged from the locking recess of the pivot bolt. In this position, the pivot bolt is still in its open position, while the locking bow has already taken a locking position. Now, if subsequently the pivot bolt transferred from its open position to its closed position or rotated, the lever takes automatically or automatically by reducing the restoring force the position in which it engages in the Sperraussparung the pivot bolt.

In this embodiment of the invention, it is advantageous that the locking bow can automatically be transferred from its release position into its locking position within a certain time window, without the pivot bolt of the pivot bolt lock also having to be transferred from its open position into its closed position. If subsequently the pivot bolt is transferred from its open position into its closed position, the adjusting device with the locking bow and the lever assumes its original position, in which the pivot bolt lock is protected against violent action and against acceleration and vibration forces against accidental opening.

It has also proved to be advantageous that, for generating the restoring force between see the locking bow and the lever, a spring, in particular a compression spring is provided. By means of such a spring, in particular a compression spring, it is possible in a simple manner to build up such a restoring force between the lever and the locking arc in their pivoting against each other.

According to another advantageous embodiment of the invention, the lever is pivotable about an axis against the locking arc, wherein the locking arc is rotatably mounted in the housing about this axis. In this way, a structurally very simple pivoting of the lever and the locking arc is given to the same axis, so that the mechanism of the entire adjusting device considerably simplified, since only one pivot axis for the two elements lever and locking bow is provided. As a result, not only is a simplification of the adjusting device of the pivot bolt lock according to the invention given, but also a component minimization is achieved, so that also simplifies the process engineering production of the pivot bolt lock according to the invention and thereby of course also lower production costs and material costs. It may also be that this axis is not firmly positioned during the process of the locking bow within the housing of the pivot bolt lock according to the invention, but also moves within the housing. Advantageously, a cylindrical opening is provided in the locking bow, in which a pin assembly rests on a compression spring, which is guided by corresponding openings of the locking bow and the lever, wherein both the locking bow and the lever is pivotable about this pin arrangement. By this embodiment of the invention, it is possible in a simple manner, the two elements lever and locking bow to pivot about the same axis. In order to enable the pivoting, the pins have a circular cross section, which is perpendicular to this axis or to the longitudinal axis of the pins.

In this case, it is further provided that the pin arrangement is formed with a conical end, which can be accommodated in a corresponding receptacle of a housing cover of the housing lying opposite the cylindrical openings. Thus, it is ensured in a simple manner that the pin arrangement, about which the locking bow and the lever are pivotably held, securely in the closed by the housing cover Ge housing is included and ensures a proper and secure locking function of the pivot bolt lock according to the invention.

In this case, according to a further aspect of the invention, it can also be provided that the pin arrangement consists of a pin assigned in the locking bow and a pin assigned to the lever, wherein the pins are axially displaceable relative to one another when the pivot bolt is in its open position. In this position, namely arranged in the opening of the locking bow pressure spring is pressurized, since the pin assembly has emerged with its conical end from the receptacle of the housing cover. If, in this position, the locking bow is now transferred from its release division into its locking position, the pins assigned to the locking bow and the lever are displaced axially relative to one another, so that pivoting of these elements about a common axis is no longer possible. Furthermore, the pivot bolt according to a particular embodiment of the invention

Conversion of its closed in its open position acted upon by a restoring force. This ensures that the pivot bolt is automatically transferred by reducing the restoring force automatically from its open position to its closed position when the restoring force is greater than a holding force holding the pivot bolt in its open position, or if such a holding force is no longer on the pivot bolt acts.

It has been proven that for generating the restoring force a spring, in particular a tension spring is provided. The tension spring is attached on the one hand to a receptacle of the housing and on the other hand to the pivot bolt.

For attachment of the tension spring on the pivot bolt, a pin may be provided which is arranged in an opening of the pivot bolt.

According to a further aspect of the invention, the pivot bolt on a permanent magnet, which is also pivoted during pivoting of the pivoting bolt. This permanent magnet now serves, by means of a corresponding detector or a corresponding electronics automated to detect the position of the pivot bolt. In this way it can be ensured in a simple manner that the closing or open position of the pivot bolt is reliably detected by an electronic device in a simple manner. This detection of the position of the pivoting bolt is achieved by the fact that the position of the permanent magnet changes as the pivoting bolt is rotated and thereby also the magnetic field lines which flow through the corresponding detector of the electrons change.

It may be provided that the permanent magnet is also disposed in the opening of the pivot bolt, in which also the pin is arranged for fastening the tension spring on the pivot bolt.

According to a further aspect of the invention, a solid sleeve is provided to protect a lock bushing, which is preferably provided with a collar and made of hardened steel or a non-chip removal material, such as manganese, consists, and is inserted between the housing and housing cover.

As already mentioned, spindle locks are often used in safe locks for moving locking elements. The winding pitch and the winding flank angle are selected such that a self-locking effect of the transmission is achieved. As a result, forces acting on the transmission output (in the event of manipulation attempts), for example caused by strong accelerations, can not cause the transmission to move back. The locking element remains at rest and the locks remain securely closed. However, these gearboxes present problems at the input side when a lock must again open in a targeted manner under code clearances.

If, in fact, the spindle drive can not be switched off in a timely manner during a preceding closing movement, the threaded bushing or the spindle nut usually reaches an end stop in the housing. In doing so, it contracts against the spindle due to the residual effect of the mass moment of inertia, caused by the rotor assembly of the drive motor of the spindle drive and by the motor torque itself. If the lock is to be reopened later after code release, the starting torque of the drive motor of the spindle drive, now acting in the opposite direction, is insufficient Jamming between spindle and threaded bush or to solve again. In this case, the lock and thus the vault could not be opened.

In order nevertheless to enable the use of such spindle transmissions in safe locks without very precise end position shutdown, solutions for bypassing jamming at the spindle transmission input were found, as mentioned in WO2011 / 127310 A1. In the approach proposed there, however, there is the problem that the spring-mounted motor with spindle must be moved and thus the forces on the spindle and spindle nut are still relatively high. So that jamming still does not occur, the spindle pitch, borderline with respect to the self-locking capability of the transmission, must be large. By the big one

However, there is a problem with the gradient that the lock is not shock-resistant in the case of large acceleration excitations and the transmission can only develop a small displacement force for locking elements. According to a further aspect of the invention it is therefore provided that the spindle has at its ends regions on which the threaded bushing or the spindle nut is freely displaceable on the spindle designed as a shaft. In order to be able to fully utilize the self-locking of the spindle gear, the spindle is thus completely equipped with windings only in the desired travel range. These can be formed very flat in slope and flank angle. Even actual fastening threads such as metric threads or metric fine threads can be used there. In order to prevent tightening of the spindle relative to the spindle nut or the threaded bushing, the housing stop of the spindle nut or the threaded bushing must not yet be reached at the respective two ends of the formed spindle thread. Rather, the spindle nut or the threaded bush can slide on remote, smooth mandrels of the spindle in front of and behind the trained turn. Here, the outer diameter of the mandrels is tuned so that they can slide with little play against the inner diameter of the thread crests of Spindelmuttergewindes or the threaded bushing thread. When moving the spindle nut or the threaded bushing through the drive is achieved so that the spindle nut or the threaded bush is disengaged in their end positions and no forces acting on the transmission. As a result, jamming between the spindle and the spindle nut or the threaded bush in the end positions is no longer possible. In a further embodiment of the Erindung is at least one spring, which is preferably designed as a leaf spring, is provided which presses the gates of the threads in the spindle nut or the threaded bush and the spindle to each other. In order to allow directional reversal to retract or advancing locking elements, that is, to open and again shoot the safe lock, a gripping the threads on the spindle and the spindle nut or the threaded bush, the spindle nut or the threaded bushing to the threads of the spindle one or two springs permanently lightly pressed. The least one spring (s) can of course also act on other coupled to the spindle nut mechanical components to ultimately cause the effect between spindle nut and spindle.

In order for the threads to always engage securely, they must be formed or start to have a very sharp edge on the spindle and on the spindle nut or the threaded bushing. This can be relatively easily realized when on the threaded spindle ends recesses and in the spindle nut on the threaded inputs surfaces or attached. Another solution by highly trained bevel at the respective threaded ends or thread starts is also conceivable.

Other objects, advantages, features and applications of the present invention will become apparent from the following description of an embodiment with reference to the drawings. All described and / or illustrated features alone or in any meaningful combination form the subject matter of the present invention, also independent of their summary in the claims or their dependency.

Swivel bolt lock.

1 shows the internal structure of an embodiment of a pivot bolt lock according to the invention. In this case, this pivot bolt lock has a housing 2, which is provided with an opening 20, through which a pivot bolt 1 can be pivoted and thus can be transferred from an open position into a closed position of the pivot bolt lock. In the illustration of Figure 1, the pivot bolt 1 of the pivot bolt lock is shown in its closed position, in which a locking element 21 of the

Pivoting bolt is pivoted through the opening 20 of the housing 2 out of this. The pivot bolt 1 is mounted pivotably on a bearing 14. Furthermore, the pivot bolt lock on an adjusting device with which the pivot bolt 1 are locked in its closed position and this blocking can be canceled, so that the pivot bolt 1 can be transferred from its closed position to its open position or pivoted. The adjusting device has for this purpose a spindle drive 7 driving a spindle 7. On the spindle 7, a threaded bush 6 is arranged, which is arranged in a rotatably mounted in the housing 2 locking bow 4. By means of the spindle drive 8, the spindle 7 and the threaded bushing 6, the locking bow 4 can be pivoted between a locking position and a release position. In the figure 1, the locking bow 4 is shown in its locking position, in which the on the one end of the locking bow 4 arranged threaded bushing 6 rests on the spindle drive 8 opposite end of the spindle 7.

At the threaded bush 6 opposite end of the locking bow 4, this is connected to a lever 3. In the closed position of the pivoting bolt 1 and the locking position of the locking bow 4 according to FIG. 1, the lever 3 engages in a blocking recess 22 of the pivoting bolt 1. In this case, the lever 3 is located with its free end, which is opposite to the end, with which the lever 3 is connected to the locking bow 4, to a system 33 in the locking recess 22 of the pivot bolt 1 at. The lever 3 engages, so to speak, as a lock in the Sperraussparung 22 of the pivot bolt 1 a. As a result, the pivot bolt 1 is blocked in its rotary or pivoting movement, so that the pivot bolt 1 is locked in its closed position.

The lever 3 is also received rotatably or pivotably in the locking bow 4. For this purpose, the locking bow 4 has an opening 24 and the lever 3 has an opening 27. In this case, a compression spring 25 is received in the opening 24 of the locking bow 4, on which a pin arrangement consisting of pins 9 and 10 rests, which extend through the openings 24 and 27 of the locking bow 4 and the lever 3. In this case, the pin 9 is in the closed position of the pivoting bolt 1 as shown in FIG 2 partly in the opening 24 of the locking bow 4 and partly in the opening 27 of the lever 3. Immediately following the pin 9 follows in the opening 27 of the lever 3 now the pin 10, which is conical at its end 9 opposite the pin 9. With this conical end 18 of the pin 9 projects out of the opening 27 of the lever 3 and engages in the closed position of the pivot bolt 1 according to the figure 2 in a cylindrical opening 24 of the locking bow 4 opposite corresponding receptacle 28 of a housing cover 11 of the housing 2 inside. In this position, the longitudinal axes of the pins 9 and 10 and the compression spring 25 and the openings 24 and 27 of the lever 3 and the locking bow 4 form a common axis 23 about which the locking bow 4 and the lever 3 are mutually pivotable or rotatable.

To transfer the pivot bolt 1 from its closed position to its open position, it is now necessary to move the individual elements of the adjusting device such that the lever 3 in a release position of the locking bow 4 out of engagement with the locking recess 22 of the pivot bolt 1 is. This position of the adjusting device is shown in Figure 3, wherein the threaded bushing 6 has been moved on the spindle 7 by means of the spindle drive 8 so that it is from the lying at the free end of the spindle 7 position as shown in Figure 1 to that on the spindle drive 8 adjacent end of the spindle 7 was moved. By the method of the threaded bushing 6 on the spindle 7 and the locking arc 4 and the associated lever 3 has been moved so that the lever 3 is no longer engaged in the locking recess 22 of the pivot bolt 1 now. In this position, the pivot bolt 1 is now on the bearing 14 such pivoting or rotatable that the pivot bolt 1 can be pivoted or rotated so far until the lever 3 comes to rest on a system 16 of the pivot bolt 1, wherein the locking element 21 of the pivot bolt 1 and the pivot bolt itself is now completely received in the interior of the housing 2. The lever 3 is in this embodiment in this position, as shown in Figure 3, substantially on a latch back 15 of the pivot bolt 1 at. The pivot bolt 1 is shown in FIG 3 now after its pivoting in its open position, so that provided with the pivot bolt lock container, such as a vault, not shown here, can now be opened.

In Figure 3, a tension spring 29 can also be seen, which is on the one hand to a receptacle 30 of the housing and on the other hand to a pin 31 which is received in an opening 32 of the pivot bolt 1, attached. While this tension spring 29 in the illustration of Figure 3, in which the pivot bolt 1 has taken its open position is stretched to form a restoring force, this pivot spring 29 is not tensioned in the closed position of the pivot bolt 1 according to FIG. Using this built-up by the tension spring 29 restoring force, it is possible that the pivot bolt is automatically and automatically transferred from its open position to its closed position, as soon as this restoring force is greater than a holding force of the pivot bolt 1 in its open position or if a holding force for the pivot bolt. 1 is no longer maintained.

FIG. 4 again shows a partial sectional illustration of the pivot bolt lock according to the representation of FIG. 3. It can be seen that the received in the opening 24 of the locking bow 4 compression spring 25 has been compressed under construction of a restoring force, the pin assembly with the pins 9 and 10 in the process of the threaded bushing 6 on the spindle 7 in the position shown in FIG recording 28 in the Housing cover 11 of the housing 2 was out method. In this position, the pins 9 and 10 of the lever 3 and the locking bow 4 are now arranged so that they still form a common axis 23. However, the lever 3 and the locking elbow 4 are now movable relative to one another in such a way that the pins 9 and 10 are also axially displaceable relative to one another. Namely, the pin 10 is now completely received in the opening 24 of the locking bow 4, while also the pin 9 does not project into the opening 24 of the locking bow 4. Thus, neither the pin 9 nor the pin 10 prevent displacement of the locking bow 4 and the lever 3 against each other.

Such axial displacement of the pins 9 and 10 of the lever 3 and the locking bow 4 is shown in the partial sectional view of Figure 6. It can clearly be seen that the pins 9 and 10 no longer form a common longitudinal axis. This is achieved in that the threaded bushing 6 is now again moved by means of the spindle drive 8 on the spindle 7 until it has assumed the position on the spindle 7 according to FIG. In this position, the locking bow 4 is now back in its locking position, which he had also already taken in Figure 1. However, the pivot bolt 1 of the pivot bolt lock according to the figure 5 is still in its open position. If now the pivot bolt 1 is also pivoted back into its closed position according to FIG. 1 or transferred, the lever 3 is automatically and automatically transferred to its position according to FIG.

So that the lever 3 is automatically and automatically transferred to this position, a compression spring 5 is arranged between the lever 3 and the locking bow 4, which during the transfer of the threaded spindle 6 from the position shown in Figure 3, in which the locking arc in its release position is, in the position shown in Figure 5, in which the locking sheet 4 is again in its locking position, between the lever 3 and locking sheet 4 under construction of a restoring force stretched. If subsequently the pivot bolt 1 is transferred from its open position according to FIG. 5 into its closed position according to FIG. 1, the lever 3 slides on a bolt back 15 of the pivot bolt 1 until the pivot bolt 1 reaches its closed position according to FIG. 1, whereby then by the restoring force the compression spring 5 is transferred between the lever 3 and locking bow 4 of the lever 3 in the locking recess 22 of the pivot bolt 1, in which the lever 3 with its free end turn turn on the system 33 of the locking recess 22 of pivoting wargeis 1 comes to rest. In this case, the pins 9 and 10 are converted into their position according to the figure 1 by reducing the built-up within the compression spring 25 restoring force.

In this case, the pins 9 and 10 also move upwards again and the lever 3 and the locking arc 4 are locked again in their blocking position according to FIG.

According to the invention it can also be provided in this embodiment that the spindle drive 8, the threaded bushing 6 on the spindle 7 after transferring the locking bow 4 from its locking position to its release position within a certain time window, for example 3 seconds, again the locking arc 4 in his Transferring locked position, so that only this time window remains available to open the pivot bolt lock or for rotating the pivot bolt 1 from its closed position to its open position. If this time window is exceeded, the pivot bolt 1 can not be transferred from its closed position to its open position, since the locking bow 4 has now taken back its locking position and thus the lever 3 is received in the locking recess 22 of the pivot bolt, in which he twisting or Swiveling the pivot bolt 1 prevents. In order to transfer the pivoting bolt 1 from its closed position to its open position, the locking arch 4 now only has to be transferred from its locking position into its release position.

The driving of the spindle drive can be done by means of a not further explained here electronics. Furthermore, it can be arranged on the pivot bolt 1, in particular in the opening 32 for the pin 31, which holds the tension spring 29, a permanent magnet. By means of such a permanent magnet, it is by means of an electronic or detector unit not shown here by means of magnetic fields or magnetic field changes to determine the position of the pivot bolt 1. In particular, the closure position and the open position of the pivoting bolt can thus be detected in a simple manner with the aid of this electronics or detector unit, without having to reinsure visually or manually the position of the pivoting bolt. Furthermore, to protect a lock bushing a solid provided with a collar 13 sleeve 12 made of hardened steel or other not suitable for chip removal materials such as manganese between the housing 7 and the lock housing cover 11 is used, as shown by way of example in Figure 7 in a sectional view is.

FIG. 8 now shows a plan view of a detail of an exemplary embodiment of a pivot bolt lock according to the invention. It can be seen that the spindle nut or the threaded bushing 6 is seated on the offset spindle 7. In addition, the spindle 7 is directly fixed to the motor shaft of the drive motor 8. Further, a leaf spring 12 can be seen, which ensures in the end positions on the concern on the locking bow 4 that the spindle nut or the threaded bushing 6 is always pressed to the thread starts.

In the illustration of Figure 8, the locking arc 4 is just in the opening movement, that is, the drive motor 8 runs to the left and the spindle nut or the threaded bushing 6 moves with the locking arc 4 to the motor 8 out. In this case, a lower side wall 4a of the locking bow 4 sets from a certain way to a lower leaf spring leg 34a of a leaf spring 34 and tensions this easily. After progression of the path finally reaches the spindle nut or the threaded bushing 6 completely on the lower, remote without threads equipped area 7a of the spindle 7. As a result, it is no longer in engagement of the thread from a certain point and the feed of the spindle nut or the threaded bushing 6 stops , After a shutdown of the drive motor 8, for example via a timer, the lock is open.

Wrd the drive motor 8 now driven in the right direction for the closing process, the threads can mutually engage again, as are pressed by the prestressed leaf spring leg 34a, the thread starts of spindle thread and spindle nut thread over the Verrie- gelungsbogen 4 together. Upon successful intervention, the spindle 7 and the locking bow 4 run away from the motor 8 upwards. During the closing movement, the upper side wall 4b of the locking sheet 4 reaches an upper leaf spring leg 34b of the leaf spring 34, and it is easily tensioned. After complete closing movement now reaches the spindle nut or the threaded bushing 6, the upper smooth stepped portion 7b of the spindle 7. It rotates after the disengagement coming of the thread, the spindle 7 in the spindle nut or the threaded bushing 6 through and the feed stops almost without force , After timeout or limit switch the drive motor 8 is then turned off. If the lock is to be opened again, the drive motor 8 is driven left-handed in the direction of rotation, by the bias of the leaf spring leg 34b straight thread of the spindle nut or the threaded sleeve 6 and the spindle 7 again engaged and the Verriege- arc 4 is about the spindle nut or the Threaded sleeve 6 is retracted in the direction of the drive motor 8. At this moment, the starting point of the sequence is reached again and all further operations are repeated for each opening and closing.
