Description

The invention relates to a control technology actively unlockable and control technology actively lock lock, as well as a storage machine for the distribution, transfer or temporary storage of items, as indicated in claims 1 and 19.

An electrically unlockable or unlockable lock, which is mainly used for storage machines, automated locker systems or the like., Is from the EP 2 176 477 B1 , which dates back to the applicant known. A lock is described in which a locking element fixedly connected to a compartment door can penetrate into the lock through an opening in the housing of the lock. In the lock a pawl is arranged, which can detect or block the locking element either directly or indirectly via a coupling member when the door is closed, and thus prevents an opening of the door. The pawl is actively pivoted out of the blocking position by supplying an approval signal into the lock electronics by means of an electric drive element, so as to release the blocking element or optionally the coupling member, and to allow the door to open. When closing the door, the pawl is urged by a spring force acting on it in the locked position, so that the compartment door is locked again. This locking operation occurs without supply of electric current and without the need for a control signal in a passive manner. In the event of a deliberate or otherwise caused power failure, or in the event of a defect in the electronic control, or if the storage machine is disabled due to a fault, the compartment door can not be opened until accidental or unauthorized pressing until the lock again has been supplied with power and / or if necessary a repair has been carried out.

In storage machines with larger compartments, which may be required or appropriate depending on the intended use, is not completely ruled out that climb in the case of unlawfully left open after a pickup compartment doors unattended children in such a subject. Does it come in addition to a decommissioning of the machine, a risk from unintentional trapping would be conceivable. Other abuse by unauthorized persons to use the machine would be conceivable.

The present invention has for its object to provide an electrically controlled lock or a self-service storage machine, which or which reduces the risk potential for people or animals and reliably prevents the unauthorized obstructing open compartment doors.

This object of the invention is achieved by the measures specified in claim 1. By means of the safety device according to the invention, it is ensured that in the case of a deliberately caused or caused by external circumstances interruption of the power supply for the storage machine or for a functionally connected to the castle, higher-level control device locking the compartment door is prevented by means of the lock according to the invention. This reliably prevents unauthorized locking of open compartment doors and minimizes the risk of inadvertent or play-related confinement of children and / or animals.

The lock of the invention advantageously eliminates the typically existing control-technically passive lockability of a compartment door by an electromechanical mechanism which is actively to be controlled and which comprises the specified safety device. This safety device reliably prevents an uncontrolled, erroneous or unauthorized locking of a previously unlocked lock in the absence or absence of a high-energy release signal, for example in a power failure or failure of the castle connected with the effect, higher-level control. Thus, the risk of a potentially dangerous condition due to erroneous or unauthorized interlocking while, for example, a living being is inside the receiving compartment, is further reduced further.

In particular, expediently, the design of the safety device according to the invention is also with respect to a later decommissioning or deactivation of equipped with the lock according to the invention locker-like storage or storage machines at the end of their life. By the described safety device Here too, the risk of the occurrence of a problematic situation is minimized.

A further advantage is that the lock according to the invention has a mechanically simple and compact structure in which as few moving parts are formed.

In addition, for unlocking and locking the lock relatively simple drive elements, which allow a cost-effective and structurally simple automation of the castle, can be used. In addition, it is advantageous that the electric drive elements are activated or supplied with power only for the respective active unlocking or locking operations, so that an electrical activation of the lock with relatively low, electrical power requirement is made possible.

Finally, the mechanical and electrical components of the lock including the safety device can be implemented in a relatively compact manner in the housing of the castle. Thus, a compact, one-piece, lock can be built, which can be installed quickly and easily in a storage machine or storage compartment.

In particular, it can be prevented by the inventively constructed lock that, for example, a child or an animal passes in an open compartment door in a locker room and the compartment door is locked with interrupted power only by pushing. This reduces the risk of trapping playing children or animals or of placing and locking objects in open slots.

Another advantage is an embodiment of the lock according to claim 2, since a secure locking of closed compartment doors is ensured even in the event of a power failure. The specified measure prevents the safety device from triggering an automatic opening of a locked compartment door.

The embodiment according to claim 3 increases the security against manipulation of the castle, since characterized on the locking mechanism of the castle, especially with locked compartment door, constantly a pivoting force acts on the pawl. This pivotal force counteracts any manipulation force that may be introduced from the outside, which has the purpose of removing the pawl from its blocking position.

By a procedure according to claim 4, a controlled, automatic and reliable activation of the safety device is ensured in the controlled unlocking of the compartment door, so that the blocking element is immediately in its blocking position and remains in the blocking position such that only by a subsequent active, energy-latched interlock signal or an energization of the second drive member, the spring force of the second spring means overcome and a transfer of the blocking element is made possible in the release position. As a result, in the de-energized state of the lock or the higher-level control device, the compartment door can not be locked so that the occurrence of a potentially dangerous condition is prevented as far as possible.

The measure according to claim 5 is therefore advantageous, since this activation of the safety device is prevented in the locked state of the compartment door, whereby a high locking security of the castle or a receiving compartment equipped with it is guaranteed. Furthermore, this measure effectively prevents unintentional or unauthorized unlocking of the lock when the compartment door is closed, regardless of whether the lock or the higher-level control device is supplied with power or in the de-energized state.

The advantageous embodiment of the safety device according to claim 6 ensures that in the event of an interruption of the power supply, the pawl when the open compartment door, ie in the unlocked state of the lock, can not get into the locked position. As a result, unintentional or caused by other causes locking the compartment door can be prevented by the castle.

The configuration of the means for holding the blocking element in its blocking position according to the features of claim 7 represents an efficient and reliable variant for preventing a provision of the blocking element from the blocking position to the release position. By this measure, it is ensured that a compartment door through the Higher-level control device for the lock can be locked only during the presence of an energized latch signal or only in normal operating conditions.

Particularly useful is the formation of the means for holding the blocking element in the blocking position according to the features of claim 8, since this represents a structurally particularly simple and robust to be realized variant.

A procedure according to the features of claim 9 allows in particular the detection of the closed position of the compartment door. As a result, the state of the receiving compartment, ie whether the compartment door is open or closed, be detected electronically. In particular, it is reliably detected whether the blocking element has entered the housing of the lock sufficiently far enough to allow the compartment door to be locked by the locking pawl. Furthermore, so incompletely closed or improperly locked compartment doors can be automatically detected by combining or linking with other state information. As a result, appropriate countermeasures can be initiated by a higher-level control device or specific requests can be made to an operator.

Another advantage is the formation of a motion transmission element for actuating the first detection means, as indicated in claim 10. With this configuration, the first detection means can be arranged deep inside the lock or as far as possible from the compartment door. As a result, a manipulation of the first detection means from the outside is considerably more difficult, and thus increases the reliability of the lock.

The measure according to claim 11 is a reliable and rapid signaling of the closed position of the compartment door available, so that the lock of the compartment door can be activated immediately. As a result, the energization of the lock to allow a lock the compartment door can be limited to the shortest possible period. This allows a low-cost control electronics and the lowest possible energy consumption, which may be important, for example, in self-sufficient power supply, especially in bridging or emergency power supply.

The features of claim 12 represent a particularly simple to implement yet reliable design variant for the motion transmission element.

Another advantage is an embodiment of the blocking element as described by the features of claim 13, as a means for limiting the pivoting of the pawl in the direction of its locking position is available. A thus generated exemption between the pawl and the coupling member is particularly advantageous for increasing the security against manipulation of the lock, because thereby a locking position of the pawl can be defined, in which a possible manipulation-proof locking effect is achieved. In addition, can be dispensed with such an embodiment of the blocking element to another training or assembly of a separate or structurally independent limiting element in the housing of the castle, whereby the structure can be simplified and the manufacturing cost of the lock housing can be reduced. The generated in this manner limitation of the pivoting movement of the pawl in the direction of the coupling member further offers the advantage that the pawl even after a plurality of cycles of actuation of the castle, the optimal locking position, in which the planned barrier and tamper resistance is achieved occupy , In particular, such a design is particularly wear-resistant or wear-resistant in the long term, since a load-transmitting support of the pawl on the coupling member is avoided.

By the measures according to claim 14 on the one hand manipulation attempts and on the other hand malfunctions on the lock or on a receiving compartment equipped therewith control technology can be detected. In particular, it can reliably be detected whether the pawl is in its blocking position, which makes possible technical differences in combination with the state information acquired by other detection means in case of any deviations from planned operating states of the lock.

Due to the design of the lock according to the features of claim 15 control technology can be determined whether the lock or its safety device is working properly. Furthermore, in conjunction with other detection means, inferences can be drawn about non-compliant states. In addition, when certain Parameter combinations automatically trigger an alarm or signal an error condition.

Particularly useful is the use or installation of a balance element, as described in claim 16. In this case, the balance element expediently acts as a counterforce to the pawl which balances in terms of force, so that in particular the manipulation safety of the lock can be additionally improved.

By the embodiment specified in claim 17, a structurally simple and reliable operation of the second detection element is realized. Furthermore, the manufacturing costs for the lock and the size of the lock can be kept as low as possible.

The configuration or the storage of the blocking element according to the features of claim 18 provides the advantage that low friction forces occur when adjusting the blocking element. This increases the operational reliability of the safety device. In addition, as the life of the safety device or the lock can be increased. In addition, as a relatively Verklemmungsfreie adjustment of the blocking element between the blocking position and the release position or vice versa can be realized, whereby the probability of the occurrence of a malfunction can be significantly reduced.

Furthermore, the object of the invention is also achieved by a storage machine according to claim 19. The achievable with a demgemäßen storage machines effects and technical effects can be found in the previous description parts.

In the measures according to claim 20 it is advantageous that an unintentional or otherwise caused closing a compartment door of a storage machine is prevented in an interruption of the power supply. Nevertheless, in a deliberately induced or caused by other circumstances power failure ensures the secure locking a closed compartment door. In addition, even when an error or defect occurs in the control device, a potentially safety-critical state is held back. Finally, by the measures according to claim 21, the personal safety can be increased because the closing and locking an open compartment door is linked to the specified, control technology easily detectable conditions.

The embodiment of the storage machine according to claim 22 has the advantage that smaller storage compartments, in which inclusion of a child can be practically excluded, structurally simpler or less expensive locks can be assigned without safety device. For this example, a castle, as in the EP 2 176 477 B1 described, are used. This modular use of locks with different levels of expansion allows needs-based, cost-effective and nevertheless reliable total solutions for storage machines.

Finally, the measure according to claim 23 ensures that forcible opening of a locked compartment door, even if this compartment door has relatively large dimensions, in particular a relatively large height, is as far as possible prevented or at least considerably impeded.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location.

Fig. 1 shows a perspective view of an inventively designed lock 1 with removed side or lid part. This lock 1 is mainly for storage machines - Fig. 4 -, Especially for Schließachssysteme or so-called parcel depots, which are intended for use by a general or possibly registered group of people, particularly suitable. In particular, by means of this lock 1 a schematically indicated compartment door 2 for a receiving compartment within a compartment arrangement of the storage machine - Fig. 4 - Control technology lockable and lockable. For this purpose, the lock 1 according to the invention is connected to an electrical control device which can accomplish an automated or remote unlocking of the lock 1, if an access authorization to the corresponding, previously closed by the compartment door 2 storage compartment is present. Likewise, the control device may be designed such that a locking of the compartment door 2 is controlled as soon as a corresponding control signal is triggered by manual closing or pushing the compartment door 2 and there is an authorization to lock the corresponding compartment door.

The lock 1 has a stable housing 3 as possible. An extension of the housing 3 can parallel to the depth direction of a compartment according to arrow 4 in Fig. 1 run. By means of the lock 1 can be controlled in connection with the compartment door 2 access to the receptacle. The housing 3 of the lock 1 comprises at least one plate-like base part 5 and possibly an unillustrated, cover-like side or upper part, between which the interior is defined for receiving the electromechanical lock components. In this case, mechanical or electrical components of the lock 1 are stored or received either inside the correspondingly solid and robust running housing 3 or on the base part 5, which at best taken alone forms the housing 3.

According to the example, the base part 5 has a bend 6, which forms an end wall plate 7 of the housing 3. In this end wall plate 7, an opening 8 is formed, which allows entry of a locking element 9 or a corresponding locking pin in the housing 3 of the lock 1. This blocking element 9, which may be hook-shaped, bow-shaped or eyelet-shaped, for example, or may be formed by a locking pin with undercuts or with cross-sectional widening, preferably via a mounting plate 10 as rigid and tear-resistant connected to a corresponding compartment door 2, in particular screwed , In the Fig. 1 the position of the locking element 9 is shown with dashed compartment door 2 by dashed lines, and designated as a blocking element 9 '.

According to an advantageous embodiment, the mounting plate 10 for the locking element 9 'in the closed and locked state of the compartment door 2 with the interposition of at least one Distanzierungs- and Schraubbefestigungsmittels 11 for the mounting plate 10 on the compartment door 2 load-transmitting on the housing 3 of the lock 1, in particular at its Support end wall plate 7. This Distanzierungs- and Schraubbefestigungsmittel 11 is preferably made in one piece, block-like, but it may also be formed for example by one or more cylinder body, which mutual support between the compartment door 2 and between the mounting plate 10 for the locking element 9 and 9 'and the Ensure housing 3 of lock 1. This prevents, among other things, that the locking element 9 or 9 'in an impact or pressure on the compartment door 2 can penetrate inadmissibly far into the housing 3, whereby damage to the lock mechanism and the lock electronics can be kept in a simple manner hinan ,

The lock mechanism described is particularly simple and at the same time executed relatively tamper-proof. Within the housing 3 of the lock 1 according to the embodiment according to Fig. 1 a coupling member 12, which is preferably formed by a so-called rotary latch 13, mounted for the construction and to cancel a mechanical coupling between the locking pin or the locking element 9 'and a pawl 14. This coupling member 12 for the positive retention of the locking element 9 'and a corresponding holding or locking pin is taking its locking position for the compartment door 2 - as in Fig. 1 has been shown schematically - of the pivotally mounted pawl 14 with respect to a movement in its open position - in Fig. 1 not shown - blocked. In the open position of the coupling member 12, the locking element 9 and the coupling member 12 are disengaged, so that the locking element 9 is released from the housing 3 of the lock 1 and the compartment door 2 can be opened.

The preferably formed as a rotary latch 13 coupling member 12 is rotatably mounted about an axis 15 which extends transversely to the direction of insertion of the locking element 9 in the lock housing 3. The rotational mobility of the rotary latch 13 about the axis 15 is regulated via the pawl 14, in particular released or locked. In the in Fig. 1 illustrated locking position of the lock 1, the pawl 14 locks a rotation of the catch 13 in the opening direction and thus keeps the catch 13, the locking element 9 'engaging therein within the housing 3 of the lock 1 fixed. When taking the release position by the pawl 14, the rotary latch 13 can be pivoted or pivoted in the opening direction, so that a withdrawal of the locking element 9 is made possible from the housing 3, as is required to open the compartment door 2.

Preferably, the catch 13 is - as is known - biased by a spring means 16 in the opening direction, so that the rotary latch 13 is urged in inactive position or release position of the pawl 14 in the open position, whereby the compartment door 2 via the form-fitting engaging therein locking element 9 ' jumps open at least a crack.

The pawl 14 is coupled to a first drive member 17, preferably with a first electromagnet 18 in the manner of a tie rod magnet, motion-coupled. In particular, the position of the pawl 14 by means of the first drive member 17 can be controlled automatically converted into a release position, in which there is a rotational movement of the rotary latch 13 in the direction of its open position.

The pawl 14 is preferably designed as a two-armed lever, the first lever arm 19 represents the pawl 14 and cooperates with the coupling member 12. The second lever arm 20 is in motion connection with the preferably electrically activatable first drive member 17. In particular, the second lever arm 20 of the pawl 14 with the linearly movable armature 21 of the first drive member 17 via a link 22 such movement coupled such that the linear downward or upward stroke of the armature 21, the pawl 14 from its locked position - Fig. 1 - Is transferred to its release position, or can be transferred from its release position to the locked position. In this case, the pawl 14 each performs a pivoting movement about a pivot axis 23.

Furthermore, it can be provided that a balance element 24 is coupled in a coupled manner via the articulated connection 22 to the first drive element 17 or to its armature 21. This balance element 24 is also designed as a lever, wherein the first lever arm 25 of the balance element 24 via the hinge connection 22 with the first electric drive member 17 is in motion connection. Due to the linear downward or upward stroke of the armature 21, the balance element 24 performs a pivoting movement about its pivot axis 26. The hinge connection 22 is configured such that the pawl 14 and the balance element 24 are coupled to each other in motion via the hinge connection 22. To improve the security against manipulation of the lock 1, the balance element 24 and the pawl 14 and the armature 21 of the first electric drive element 17 are expediently at least approximately balanced in terms of mass and / or force. The three motion-coupled elements pawl 14, balance element 24 and armature 21 are balanced such that when initiating translational or rotary pulses in the lock housing 3, such as violent impact on the storage machine or a compartment door 2 possible, no resulting movements of these three coupled Elements and thus not the pawl 14 may occur and thus the compartment door 2 remains reliably locked.

Conveniently, a first spring means 27 is formed by the spring force, the pawl 14 is continuously or continuously urged into its blocking position or locking position. This spring means 27 may be associated directly with the pawl 14, but it may also be associated with the first drive member 17 and the armature 21. According to the example, the spring means 27 is assigned to the automatic transfer of the pawl 14 in the blocking position of the balance element 24 and causes in the energy-less or non-energized state the first electric drive member 17 is an extended position of the armature 21 relative to the drive member 17, whereby the pawl 14 in their in Fig. 1 shown locked position is urged.

The coupling member 12, in particular the rotary latch 13, facing the front end 28 of the pawl 14 is blunt on the coupling member 12, when the lock 1 in the in Fig. 1 shown, locked state is present. In particular, a support surface 29 is formed at the front end 28 of the pawl 14, the butt abuts a abutment surface 30 of the coupling member 12 when the pawl 14 is in the locked position. The abutment surface 30 on the coupling member 12 is at the assumption of the blocking position of the pawl 14 at right angles or at least approximately at right angles to the longitudinal axis 31 of the pawl 14 aligned.

Moreover, in Fig. 1 a safety device 32 is shown, which is assigned to the lock 1 or which safety device 32 prevents a control-technically passive locking of the compartment door 2. Rather, a control-technically active locking of the lock 1 or the compartment door 2 is caused by the safety device 32.

How out Fig. 1 for the lock 1 is visible in its locked state, the second lever arm 20 of the pawl 14 is in the region of the joint connection 22 with a blocking element 33, which blocking element 33 is formed as part of the safety device 32 in contact. This blocking element 33 preferably has a limiting means 34, which limiting means 34 is in force-transmitting interaction with a structurally independent limit stop 35 when the pawl 14 is in the blocking position. In the in Fig. 1 In the embodiment shown, the limit stop 35 is rigidly or immovably connected to the base part 5. The limiting means 34 in combination with the limit stop 35 represents the end point of the pivoting path of the pawl 14 in the direction of its blocking position, so that the blocking position of the pawl 14 is defined by the limiting means 34 and the limit stop 35. This means that the pawl 14 rests against the blocking element 33 when it assumes its blocking position in a load-transmitting or supporting manner.

The blocking element 33 can be mounted in a translational and rotationally adjustable manner relative to the housing 3 or base part 5 by means of a linear and pivot bearing 35a. A guide the linear or pivotal movement of the blocking element 33 is in the in the in Fig. 1 embodiment shown realized by a recess 35b in the blocking element 33, which recess 35b cooperates with the limiting stop 35 during an adjustment movement of the blocking element 33.

Fig. 2 represents a structural compared to Fig. 1 slightly modified embodiment of a lock 1 according to the invention. Fig. 2 shows the lock 1 in the locked state, that is, in the locking position 36 befindlicher pawl 14. In Fig. 2 For the sake of clarity, the elements of the receiving compartment which interact with the lock 1, in particular the compartment door and the locking element which can be inserted into the lock 1, are no longer shown.

How out Fig. 2 can be seen, due to the limitation of the pivoting movement of the pawl 14 via the limiting means 34 and the limit stop 35 a physical or structural clearance 37 may be formed so that the pawl 14 does not rest in its locking position 36 on the rotary latch 13 and the coupling member 12. This prevents that can be introduced by an impulse or force on the coupling member 12 and on the catch 13, which pulses on the housing 3 of the lock 1 and / or the blocking element, the pawl 14 in unanticipated or undesirable manner is moved to its unlocked position or release position.

Alternatively and / or in addition to restricting the pivoting movement of the pawl 14 in the direction of the locking position 36 by the blocking element 33 may, in the Fig. 1 to 3 not drawn, arranged separately, in particular a structurally independent limit stop to limit the pivoting movement of the pawl 14 executed. Such a separately arranged limit stop can be assigned directly to the pawl 14, but can also be assigned to the balance element 24.

At the in Fig. 2 shown locking position 36 of the pawl 14 is the blocking element 33 in its release position 38 before. The blocking element 33 is preferably associated with a second spring means 39, by whose spring force the blocking element 33 continuously in his in Fig. 3 shown blocking position 40 is urged. To automatically take the blocking position 40 by the blocking element 33 in the in Fig. 2 illustrated, locked state of the Lock 1, that is to hold in befindlichem in locking position 36 pawl 14, the first spring means 27 and the second spring means 39 are designed or matched to one another that the force which is exerted by the first spring means 27 effectively or effectively on the pawl 14 is greater than the force which is effectively exerted on the blocking element 33 by the second spring means 39. As a result of this measure, when the pawl 14 is in the blocking position 36 in the de-energized state of the first electric drive element 17, the blocking element 33 is constantly forced into the release position 38, thus effectively preventing unintentional or unauthorized unlocking of the lock 1 when the compartment door is closed, regardless of whether the lock 1 is supplied with power or is present in a de-energized state.

The pawl 14 is actively pivoted out of the locking position 36, especially in feeding a release signal into the lock 1 by means of the first electric drive member 17 or in their in Fig. 3 shown release position 41 so as to release the coupling member 12, and to allow opening of the compartment door. By this process, the force of the first spring means 27 is overcome, so that the blocking element 33 of the safety device 32 by the second spring means 39 in his in Fig. 3 shown blocking position 40 is transferred.

That in the Fig. 1 to 3 blocking element 33 shown further comprises a means 41a for holding the blocking element 33 in the blocking position 40, which means 41a is formed such that when there is no power supply for the lock 1 and for the higher-level control device, an automatic transfer of the pawl 14 of the in Fig. 3 shown release position 41 in the in Fig. 2 Lock position shown 36 is prevented. In particular, the means 41a for holding the blocking element 33 counteracts the force exerted on the pawl 14 by the first spring means 27.

The means 41a for holding the blocking element 33 in the blocking position 40 can be embodied in two parts and can be formed by a holding means 42 configured on the blocking element 33 and a holding element 43 assigned to the blocking element 33. In this case, the holding means 42 and the holding element 43 are in blocking position 40 befindlichem blocking element 33 load or force transmitting to each other, and prevent a spring force-induced transfer of the blocking element 33 in the release position 38. By this measure is a Controlled inactive or mechanically automatic locking the compartment door in the de-energized state of the lock 1 or the parent control device. Even with a manual closing or pushing the compartment door and the concomitant or enforced by the blocking element transfer of the coupling member 12 of the in the Fig. 3 shown opening position in the in Fig. 2 shown closure position, the pawl 14 can not be transferred to its locked position 36 in the de-energized state of the lock 1, as this is prevented by the blocking element 33 held in its blocking position 40.

In the in Fig. 2 respectively. Fig. 3 In the embodiment shown, the holding means 42 is configured as a bearing surface 44 formed inside the blocking element 33, which bearing surface 44 is defined by a recess 45 in the blocking element 33. This bearing surface 44 in the blocking element 33 is based on blocking element 33 located in the blocking position 33 on a holding pin 46 or holding pin fixedly or rigidly connected to the housing 3 of the lock 1, or as a load-bearing or holding-transferring pin.

Alternatively, the retaining pin 46 or retaining bolts can also be designed as an axle, which carries a bearing sleeve, not shown in the figures or a small rolling bearing, wherein the bearing surface 44 then rolls on the camp. Thereby, the frictional force between the retaining pin 46 and the support surface 44 can be significantly reduced or substantially eliminated, whereby the required force of the electromagnet 48 for transferring the blocking element 33 is reduced to the release position 38 and an overall improved reliability and long-term stability is achieved. Likewise, the wear of the retaining pin 46 and the bearing surface 44 is thereby reduced.

At this point it is noted that the in Fig. 2 and Fig. 3 shown embodiment of the lock 1 and the security device 32 is to be regarded only as an example of a variety of design options or variants for a lock 1 according to the invention. For example, the in Fig. 1 In this case, the support surface 44 is not formed by a recess in the blocking element 33, but defined by a portion of the upper edge of the blocking element 33. It is essential that the lock 1 has a blocking element 33, which blocking element 33 directly and / or indirectly Means 41 a is assigned to hold the blocking element 33 in the blocking position 40. This means 41a overcomes the force exerted by the spring means 27 on the pawl 14, which acts in the direction of its locking position 36. As a result, in the open state of the receiving compartment or the compartment door in a power interruption or other disturbance of the proper operation of the storage machine pivoting of the pawl 14 is prevented in its locking position 36, since the blocking element 33 by the means 41 a for holding the blocking element 33 in its blocking position 40 can not be converted into the release position 38.

For the purpose of locking the receiving compartment or the lock 1, the blocking element 33 is rather coupled in terms of movement with a second electric drive element 47, preferably with a second electromagnet 48 in the manner of a tie rod magnet. In the in Fig. 2 respectively. Fig. 3 In the embodiment shown, the blocking element 33 is coupled in a coupled manner via an articulated connection 49 to an armature 50 of the second electric drive element 47. In the event of an authorization to lock the receiving compartment and a signal that the blocking element has entered far enough into the lock housing 3, the second electric drive member 47 is activated by the parent control device. In the in Fig. 2 respectively. Fig. 3 shown embodiment is brought by energization of the second electric drive member 47 of the retaining pin 46 out of engagement with the support surface 44, so that then after a sufficiently wide rotation of the rotary latch 13 in the course of closing the compartment door, the pawl 14 on the bias of the first spring means 27 in the Locking position 36 is transferred, and the blocking element 33 with the movement of the pawl 14 in his in Fig. 2 shown release position 38 is raised. This results in an adjustment of the blocking element 33 via a translational and rotational movement in the Freistellpositon 38. Alternatively, a transfer of the blocking element 33 from its blocking position 40 in the release position 38 also take place directly by the second electric drive member 47.

Ultimately, it is achieved by the measures set out above, that the lock 1 can only lock the compartment door when the compartment door is energized, during this period, the second electric drive member 47 is energized and the first electric drive member 17 is not energized, so if the parent control device sends an energetic, active lock signal to the lock 1.

Preferably, a signal triggered by manual closing of the compartment door 2, which signal is used to activate the second electric drive member 47, is supplied by a first detection means 51. This first detection means 51 serves to determine whether the blocking element 9 '- Fig. 1 - Is inserted into the housing 3 of the lock 1 so that it can be locked or held by means of the coupling member 12. The first detection means 51 is thereby preferably influenced by a motion transmission element 52, which motion transmission element 52 is actuated by the manual closing of the compartment door. In particular, the motion transmission element 52 is designed as a linearly adjustable, resiliently biased plunger element 53. Im in the Fig. 2 shown latched state of the lock 1, this plunger element 53 extends between the end wall plate 7 and an actuating element 54 of the first detection means 51, in particular into the travel of a switching flag of the first detection means 51 inside. The linearly adjustable plunger element 53 is aligned at an acute angle to the actuating element 54, wherein the plunger element 53 and the detection means 51 are positioned to each other such that in an unforeseen wide, manipulative insertion of the plunger element 53 in the housing 3 of the lock 1, the end of the Plunger element 53 is moved past the detection means 51 and the detection means 51 does not act as an end stop for the plunger element 53.

In the case of present power supply for the lock 1 or for the higher-level control device and the present authorization to close the receiving compartment, in the case of triggering the first detection means 51, the blocking element 33 can indirectly or directly by energizing the second electric drive member 47 from the blocking position 40 in the Freistellposition 38 are transferred, which allows proper locking of the compartment door 2 through the lock 1.

When unlocking the compartment door triggered by control technology, a spring means 55 associated with the tappet element 53 can bring about a linear displacement of the tappet element 53 in the direction of the end wall plate 7 of the housing 3 of the lock 1. In this case, the plunger element 53 passes through an opening 56 in the end wall plate 7 partially from the housing 3, as in Fig. 3 is shown. In addition, the spring element 55 in addition to the spring means 16 of the rotary latch 13 for the opening or automatic opening of the compartment door supportively effective be.

In the course of the manual closing or closing of the compartment door 2, the plunger element 53 either through the compartment door itself or - as in Fig. 1 shown - by the connected to the locking element 9 distancing and screw fastener 11 back into the in Fig. 2 transferred shown position. As a result, the actuating element 54 of the first detection means 51 is influenced or actuated, which can be used as a control-technical signal for the activation or energization of the second electric drive member 47.

In addition, a second detection means 57 for detecting the respective position of the pawl 14, in particular for detecting at least one end position of the armature 21 of the first electromagnet 18 may be formed. This second detection means 57 can be actuated by the second lever arm 58 of the balance element 24, as shown in FIG Fig. 2 is shown. However, the second detection means 57 can also be positioned on the armature 21 opposite side of the first electromagnet 18, in particular on the armature 21 opposite side of the electric coil of the electromagnet 18. In this case, an extension of the armature 21 passes through the coil arrangement and actuates the second detection means 57. The second detection means 57, in particular for detecting the active position of the first drive member 17, in particular for detecting whether the armature 21 has been attracted by the first electromagnet 18 or not, be provided. At the in Fig. 2 the arrangement shown, the passive position of the armature 21 and the locking position of the lock 1 is detected by the balance element 24 upon actuation of the detection means 57.

Furthermore, the position of the blocking element 33 or the position of the second electric drive element 47, in particular the position of the armature 50 of the second electromagnet 48 can be detected by a third detection means 59. In this case, an actuation of the third detection means 59 can be effected by the blocking element 33, as shown in FIG Fig. 2 for the release position 38 of the blocking element 33 is shown. Alternatively, the third detection means 59 may be positioned on the side of the second electromagnet 48 opposite the armature 50, in particular on the side of the electrical coil of the electromagnet 48 opposite the armature 50.

The detection means 51, 57, 59 are preferably by electrical switching elements, in particular formed by NO and / or NC contacts. The respective detection signals or switching states of the detection means 51, 57, 59 can be transmitted via an electrical plug connection 60 to a control or evaluation device (not shown).
