Description

Field of invention

The present invention relates to a locking device for a container, in particular for a portable container.

State of the art

Lockable bags and suitcases are known from the prior art, which can be locked with a key or a mechanical combination lock or so-called “permutation lock”. Examples of such bags and cases are in DE 1 532 850 A and the DE 33 28 284 C2 described. Furthermore, for example, from the US 7,961,914 B1 Bags, suitcases and similar containers are known which can be opened by means of fingerprint recognition, as well as from the DE 20 2011 103 197 U1 those that contain other electronically controllable components and can be remotely controlled. In particular for card folders ("card holders"), such as those from the WO 2007/140778 A1 are known, and intelligent wallets ("Smart Wallets"), such as those from the WO 2009/035728 A1 are known, radio-based authentication, for example using RFID, and the integration of further biometric sensors have also been described.

In contrast, the prior art does not address the manner in which a space-saving and power-saving actuator can be accommodated in the lock, which actuator opens a pocket lock after electronic authentication.

Based on this, the object of the present invention is to provide a container, such as a bag, cover or folder, which can be locked to protect against unauthorized access such as theft, with the lock being authenticated using a key or mechanism that is not easily lost can be opened electronically.

Furthermore, these introductory expressions are intended to leave unaffected all possibilities of combining the features introduced thereby with other features, be they optional or non-optional features.

A locking device according to the invention for a container comprises a closure, an authentication interface and a Power source. The lock has at least one first locking element, at least one lock counterpart and at least one first actuator. The first blocking element is for moving between a first blocking position, in which a movement of the counterpart closure relative to the first blocking element is prevented and an opening of the container is prevented, and a first release position, in which the counterpart closure is moved relative to the first blocking element and an opening of the container is allowed. The first actuator is made from a shape memory material. The first actuator is connected to the power source. The first actuator is designed to allow a movement of the first locking element from the first blocking position into the first release position when power is supplied from the power source. The authentication interface is designed to allow a power supply from the power source to the first actuator if a user identifies himself as authorized to access the authentication interface.

In the context of the present invention, a container is to be understood as a portable or portable object which has a cavity in its interior, which in particular serves the purpose of separating its contents from its environment. Examples that are not listed exhaustively are bags, handbags, wallets, briefcases, travel bags, suitcases, jewelry boxes, credit card cases, book covers, document folders, diaries, notebooks, file folders, laboratory notebooks, mobile phone covers, tablet covers, laptop covers, ebook reader covers.

In the context of the present invention, a shape memory material is to be understood as a material that has the property of being induced from a deformed state (temporary shape) into its original shape (which was imprinted during manufacture and then permanent) induced by an external stimulus (trigger), such as for example a temperature change to return. Such shape memory materials can be shape memory polymers or shape memory alloys. Shape memory alloys are special metals that can exist in two different crystal structures, each with a different degree of lattice symmetry. They are also often referred to as memory metals. This stems from the phenomenon that they seem to be able to “remember” an earlier (imprinted) shape despite subsequent strong deformation. Shape memory alloys can have two different crystallographic structures (phases) depending on the temperature. The shape transformation is based on the temperature-dependent lattice transformation to one of these two crystal structures (allotropic transformation). As a rule, there is the high temperature phase called austenite and the martensite (low temperature phase). Both can merge through a change in temperature. Shape-memory polymers are plastics that have a shape-memory effect, that is, they seem to be able to “remember” their earlier external shape despite major changes in the meantime.

In the context of the present invention, an authentication interface is to be understood as an interface which is designed to check the authenticity of an existing access authorization claimed by an entity. In other words, the authentication checks whether an entity is authorized or authorized to access the authentication interface.

The first actuator can be a flat actuator, a coil spring or a wire. Correspondingly, the shape of the first actuator can be adapted to the particular application or structural conditions. A flat shape of the actuator is to be understood as a shape that is essentially two-dimensional, i.e. a shape whose height or thickness is significantly smaller than its length and width. For example, the actuator is cut, etched or punched from a thin film. A flat actuator has a two-dimensional actuator geometry that is adapted to the necessary direction of movement, travel and force, for example with meandering webs or spirals.

In a further development, the first actuator is made from a NiTi or NiTiCu alloy.

In a further development, the first actuator is designed to move the first blocking element from the first blocking position into the first release position. The first blocking element can thus be moved by the first actuator from the first blocking position into the first release position by means of thermal energy, for example when a heating current is applied to the actuator. A first reset element can in turn be provided for the movement from the first blocking position into the first release position.

In a further development, the first actuator is designed to allow a movement of the first blocking element from the first blocking position into the first release position by means of a movement device. The first locking element can thus be moved manually or by means of a mechanism, provided that the first actuator allows or does not prevent such a movement.

The first locking element can be linearly movable, pivotable or rotatable.

In one development, the closure furthermore has a second actuator, the second actuator being separated from the power source, the Closure further comprises a second locking element, the second actuator for moving the second locking element between a second blocking position in which the second locking element engages in the counterpart closure and prevents movement of the counterpart closure relative to the second locking element, and a second release position in which a Movement of the locking counterpart relative to the second locking element is allowed, the second actuator being designed to move the second locking element from the second release position to the second blocking position when heat is supplied from the outside, the second locking element being linearly movable, pivotable or rotatable . Thus, the second blocking element becomes active and prevents opening if the first actuator is not energized with access authorization, but an attempt is made to move it into the first release position by supplying heat from the outside.

In a further development, the closure furthermore has a second locking element, the first actuator for moving the second locking element between a second blocking position in which a movement of the first locking element relative to the second locking element is prevented, in particular by engaging the first locking element, and a second release position, in which a movement of the first locking element relative to the second locking element is allowed, is formed. In this way, accidental opening of the lock can be reliably prevented even when the first actuator is activated.

In the first blocking position, the first locking element can engage in the locking counterpart or in the second locking element. The second locking element is particularly linearly movable, pivotable or rotatable.

In a further development, the lock also has a second actuator, the second actuator being separated from the power source, the second actuator being designed to prevent the first locking element from moving from the first blocking position to the first release position when heat is supplied from the outside. In this way, unauthorized opening of the closure by heating the first actuator above its phase transition temperature can be reliably prevented.

In a further development, the second actuator is designed to counteract the first actuator in an antagonistic manner. In this way, unauthorized opening of the closure by heating the first actuator above its phase transition temperature can be reliably prevented, since the second actuator prevents movement of the first actuator.

In a further development, the lock also has a second locking element, the second actuator for moving the second locking element between a second locking position in which the second locking element engages in the first locking element or the counterpart of the lock and prevents movement of the first locking element, and a second Release position, in which a movement of the first locking element is allowed relative to the second locking element, is formed, wherein the second actuator is designed to prevent a movement of the second locking element from the second blocking position into the second release position when heat is supplied from the outside. In this way, unauthorized opening of the closure by heating the first actuator above its phase transition temperature can be reliably prevented.

In a further development, the first locking element engages in the locking counterpart in the first locking position. Alternatively, the first blocking element engages in the second blocking element in the first blocking position.

In a development, the first actuator and / or the second actuator are connected to the first blocking element or to the second blocking element. The first actuator and / or the second actuator thus interact directly with the first blocking element or the second blocking element.

In a further development, the lock also has a third locking element, the second actuator for moving the third locking element between a third locking position in which the third locking element engages in the first locking element or the counterpart lock and prevents movement of the first locking element or the counterpart lock, and a third release position, in which a movement of the first locking element or the locking counterpart is allowed relative to the third locking element, is formed, wherein the second actuator is designed to move the third locking element into the third blocking position when heat is supplied from the outside. In this way, unauthorized opening of the closure by heating the first actuator above its phase transition temperature can be reliably prevented.

In a further development, the lock also has a second actuator, which is connected to the power source, and a latching element, the first locking element defining a first latching position and a second latching position for the latching element, the latching element engaging the second latching position if the The first locking element is in the first blocking position, the locking element engaging the first locking position if the first locking element is in the first release position, the first actuator when power is supplied from the power source to the Moving the first locking element from the first release position into the first blocking position is designed and the second actuator is designed to move the first locking element from the first blocking position to the first release position when power is supplied from the power source or wherein the first actuator is designed to move when power is supplied from the power source of the first blocking element is formed from the first blocking position into the first release position and the second actuator is constructed to move the first blocking element from the first blocking position into the first release position when power is supplied from the power source. Thus, the lock can be kept in an open or closed state and does not lock by itself.

In a further development, the first locking element is preloaded into the first blocking position by means of a first restoring element. Thus, an automatic locking of the lock is realized. Such a return element can be used, since a single SMA actuator (with one-way effect) can only move in one direction. The return element is required for the countermovement.

In a further development, the counterpart closure is preloaded in a direction away from the first locking element by means of a second restoring element. In this way, when the first actuator is activated, the lock opens automatically without any further action by the user, which simplifies operation.

In a further development, the power source is a rechargeable power source, in particular a wired or wireless rechargeable power source. This eliminates the need to change the battery or the power source can be recharged again and again even after it has been drained, which simplifies operation and protects the environment. Alternatively, the power source can be a battery, such as a disposable battery.

In a further development, the counterpart closure is linearly movable, pivotable or rotatable. Accordingly, the counterpart closure can be implemented in a wide range of possible embodiments.

In one development, the power source has at least one power supply connection for connecting and charging an electronic device. Thus, an external electronic device, such as a mobile phone, can be charged by means of the power source.

In a further development, the authentication interface is designed for contactless and / or wireless checking of an access authorization, in particular by means of at least one signal selected from the group consisting of: Bluetooth, Bluetooth Low Energy, near field communication, RFID, WiFi, or a signal from a smartwatch. The lock can thus be opened by means of many different embodiments of possible access keys.

In a further development, a wireless access key for the authentication point is arranged in a piece of jewelry, such as a bracelet, an amulet, a brooch, a ring or a wristwatch. The access key can thus be accommodated in a device that is not easily lost and that can have a fashionable value in addition to its functional value.

In a further development, the authentication interface is designed to check access authorization by means of a sensor for detecting biometric features, in particular by means of a fingerprint scanner, iris scanner, face scanner or voice recognition scanner. Thus, the closure can be opened in many possible ways.

In a further development, the locking device can be controlled by means of a radio-connected mobile device, the mobile device preferably having an application for controlling the locking device. Thus, the operability of the closure can be checked by the user and controlled as required. In this way, authentication can be carried out using existing user accounts. There is also the possibility of remote access, such as for customer services, rental companies and the like. Furthermore, a user-configurable behavior of the lock is possible, which can be configured as a function of the time or position, for example.

In a further development, the container is a container selected from the group consisting of: bag, handbag, wallet, briefcase, travel bag, suitcase, jewelry box, credit card box, book cover, document folder, diary, notebook, file folder, laboratory book, mobile phone cover, tablet cover, laptop - sleeve, ebook reader sleeve. Accordingly, the closure can be integrated into a large number of possible containers.

Description of the exemplary embodiments

1 shows a schematic representation of a locking device according to the invention 100 that are in a container 102 is integrated. The container 102 is a bag in the embodiment shown. The bag has an opening 104 on which by the locking device 100 can be kept closed. The locking device 100 has a closure 106 , an authentication interface 108 and a power source 110 on. The closure 106 comprises at least one first actuator 112 . The first actor 112 is from control electronics 114 that with the first actuator 112 , the power source 110 and the authentication interface 108 is connected, electronically controllable. The first actor 112 is made from a shape memory material. A particularly space-saving actuator can thus be implemented using a shape memory alloy (SMA). A SMA actuator develops a force in the direction of a previously imprinted “memory shape” as soon as it is heated above a critical temperature Af and has been correspondingly deformed beforehand, for example by applying a heating current. On the other hand, after cooling below a second temperature Mf <Af, it loses its force and can be deformed or deflected, for example, by a pretensioning spring. Such an actuator can advantageously be planar and have meander-shaped or spiral-shaped webs. A helical spring made from a wire or a wire made from an SMA is also advantageous. Since SMA actuators are thermally activated, a second SMA actuator can optionally be integrated into a lock, which blocks the opening mechanism if the lock is fraudulently heated from the outside, instead of just the first actuator through proper authentication 112 activated electronically, as explained in more detail below. In the exemplary embodiment shown, the first actuator is 112 made of a NiTi or NiTiCu alloy.

The first actor 112 gives the (previously closed) closure 106 only free to open when it is energized. The energy is supplied via the preferably rechargeable power source 110 which is either permanently integrated into the interior of the bag or integrated in a removable pocket that is accessible from the inside and / or outside. Recharging the power source 110 can either be wired or wireless. The power source 110 can optionally also have at least one optional power supply connection 116 for connecting and charging an electronic device, for example inside the pocket. For example, the power source has 110 if this is chargeable, via an optional charging interface. The supply of the first actuator 112 with energy via the control electronics integrated in the bag 114 regulated. This is available with the authentication interface, which is also integrated in the pocket and is preferably accessible from the outside 108 in connection. An opening of the shutter 106 is only then from the control electronics 114 initiated or authorized if the user has previously logged on via the authentication interface 108 identified as authorized, ie electronically "unlocked" the bag. The Authentication interface 108 is designed for contactless and / or wireless checking of an access authorization, in particular by means of at least one signal selected from the group consisting of: Bluetooth, Bluetooth Low Energy, near field communication, RFID, WiFi, or a signal from a smartwatch. Alternatively or additionally, there is the authentication interface 108 designed to check access authorization by means of a sensor for the detection of biometric features, in particular by means of a fingerprint scanner, iris scanner or face scanner or voice recognition scanner. Various embodiments of the locking device are shown below 100 described in more detail with the in 1 shown container 102 can work together. In principle, various key principles can be used for identification or authentication, as described in more detail below. These include, among other things: contactless identification, eg with an RFID chip, NFC chip, biometric features, connection ("coupling") with a mobile device, digital sample or combination lock. In particular for the execution of the locking mechanism and the actuators there are different advantageous variants, depending on the type of use for the container 102 is provided: If there is little risk of accidental authentication, the first actuator 112 be designed so that he has the locking device 100 opens completely when activated electronically. If, on the other hand, there is a risk of accidental authentication, or if, for example, automatic closing / opening is to take place depending on time or location, then the locking device can 100 be designed so that the first actuator only releases an internal blocking mechanism and the locking device when electronically activated 100 can then only be opened fully manually.

2 shows a sectional view of a locking device 100 according to a first embodiment. The locking device 100 can with the in 1 shown container 102 work together. The closure 106 has at least one first locking element 118 , a lock counterpart 120 and at least the first actuator 112 on. The closure 106 furthermore has a lock housing 122 on that one shutter opening 124 defined in which the closure counterpart 120 engages to close. The lock housing 122 and the lock counterpart 120 are formed on opposite sides of the opening 104 of the container 102 To be attached in such a way that it can be joined by connecting clasp 106 or lock housing 122 and lock counterpart 120 by inserting the lock counterpart 120 into the lock opening 124 the container 102 closes. The lock counterpart 120 is essentially cuboid when viewed in the sectional view. However, it is explicitly emphasized that the closure counterpart 120 may have a different shape, such as cylindrical or triangular, the shape being a geometric interaction of the first locking element 118 and the lock counterpart 120 must allow for locking. The lock counterpart 120 points to one of the first locking element 118 facing side a recess or notch 126 on. The first locking element 118 is essentially wedge-shaped. The first locking element 118 has a counterpart to the closure 120 facing front end 128 and one of the locking counterpart 120 remote rear end 130 on. The first locking element 118 points at the front end 128 a slope 132 that acts as a slip plane. The first locking element 118 is in the lock housing 122 linearly movable, such as perpendicular to the closure opening 124 . So is the first locking element 118 for moving between a first blocking position in which the first blocking element 118 in the lock counterpart 120 or in its notch 126 engages and an opening of the container 102 prevented, and a first release position in which a movement of the closure counterpart 120 relative to the first locking element 118 and opening the container 102 is allowed, trained. The first locking element 118 is by means of a first return element 134 , such as a spring or coil spring, biased into the first blocking position.

The first actor 112 is a flat actuator with a 2D actuator geometry adapted for the necessary direction of movement, travel and force. The first actuator can, for example, have meandering webs or spirals or be a helical spring or a wire. The first actor 112 is at the far end 130 of the first locking element 118 arranged. The first actor 112 is via connecting cables 136 with the power source 110 connected is. The first actor 112 is designed when power is supplied from the power source 110 movement of the first locking element 118 to allow from the first blocking position to the first release position. The first actuator is more precise 112 for moving the first locking element 118 formed from the first blocking position to the first release position. The first actor 112 is designed for train. The authentication interface 108 is designed to receive a power supply from the power source 110 to the first actuator 112 to allow if a user is at the authentication interface 108 identified as authorized.

In the embodiment shown, the first locking element 118 by the passive first reset element 134 to the left into the lock opening 124 pressed in so that it is by grasping at the locking counterpart 120 or at the notch 126 pulling it out and thereby opening the container 102 prevented. The first locking element 118 is inside the lock 106 also with the energizable first actuator 112 connected. This is designed so that it is the first blocking element when the power supply is closed 118 , in the example to the right, against the force of the first return element 134 from the lock opening 124 pulls out and with it the lock counterpart 120 releases. The first locking element 118 is through the slope 132 advantageously designed so that the closure counterpart 120 easily by hand into the opening 124 can be introduced, the first locking element 118 briefly recedes (to the right) until it enters the notch 126 clicks into place. Furthermore, the mechanism is advantageously designed so that the closing force does not come directly from the first actuator 112 , but through the first locking element 118 and the lock housing 122 is caught. The first actor 112 therefore only needs the force for changing the position of the first locking element 118 raise.

3 shows a sectional view of a locking device 100 according to a second embodiment. Only the differences from the locking device are described below 100 according to the first embodiment and the same or comparable components are provided with the same reference numerals. Note that for the sake of clarity, the power source 110 and the connecting cables 136 are not shown, they are still present in the embodiment shown. In the second embodiment, the closure is the counterpart 120 by means of a second return element 138 in one direction from the first locking element 118 biased away. So is the second reset element 138 at the bottom of the shutter opening 124 arranged. The direction of the pretensioning of the second restoring element is corresponding 138 perpendicular to the direction of movement of the first locking element 118 as well as parallel to the insertion direction of the locking counterpart 120 into the lock opening 124 . The locking device 100 the second embodiment device is thus expanded by a passive ejection mechanism compared to the first embodiment. The passive ejection mechanism, which is advantageously fixed to the breech housing 122 is connected and when inserting the locking counterpart 120 is mechanically pretensioned by this, presses the counterpart of the lock 120 from the lock opening 124 out as soon as the first actuator 112 is operated by means of power supply and thus the first locking element 118 withdraws. The advantage is that container 102 after authentication and the actuation of the first actuator triggered by it 112 immediately opens completely.

4th shows a sectional view of a locking device 100 according to a third embodiment. Only the differences from the locking device are described below 100 according to the first embodiment and the same or comparable components are provided with the same reference numerals. Note that for the sake of clarity, the power source 110 and the connecting cables 136 are not shown, they are still present in the embodiment shown. In the third embodiment, the closure 106 a second locking element 140 on. The first actor 112 is to move the second locking element 140 between a second blocking position in which the second blocking element 140 movement of the first locking element 118 prevented, and a second release position in which a movement of the first locking element 118 relative to the second locking element 140 is allowed, trained. So is the first actor 112 not at the rear end compared to the first embodiment 130 of the first locking element 118 arranged, but laterally to this in the lock housing 122 . The first actor 112 has a mobility in a direction that is perpendicular to the direction of movement of the first locking element 118 is. In particular, the second locking element engages 140 in the second blocking position in the first blocking element 118 and more precisely in a first lateral recess 142 of the first locking element 118 a. There is also the second return element 138 parallel to the first actuator 112 arranged and with the second locking element 140 connected. The first actor 112 is to allow a movement of the first locking element 118 formed from the first blocking position into the first release position by means of a movement device not shown in detail. In the third embodiment, the movably guided first locking element 118 only by the first reset element 138 to the left into the lock opening 124 pressed in. For opening, the first locking element is via the movement mechanism not shown in detail 118 manually pushed to the right so that the lock counterpart 120 can be pulled out. The first locking element 118 however, is again with the second locking element 140 provided from above, which in turn with the energizable first actuator 112 for pulling out the second locking element 140 and the second, passive, restoring element in the form of a spring for pushing in the second locking element 140 is provided. As long as this second locking element 140 not by the energized first actuator 112 from the first locking element 118 is pulled out, the first locking element can 118 cannot move and therefore cannot move the counterpart of the lock 120 release. As soon as the first actuator 112 is energized, this contracts and the second blocking element 140 gives the first locking element 118 free, which is now manually pushed to the right can be and thus the lock counterpart 120 releases.

5 shows a sectional view of a locking device 100 according to a fourth embodiment. Only the differences from the locking device are described below 100 described in accordance with the third embodiment and identical or comparable components are provided with the same reference numerals. Note that for the sake of clarity, the power source 110 and the connecting cables 136 are not shown, they are still present in the embodiment shown. In the fourth embodiment, the closure 106 also a second actuator 144 on. The second actor 144 is made from a shape memory material such as a NiTi or NiTiCu alloy. The second actor 144 is from the power source 110 Cut. The second actor 144 is designed to move the first locking element when heat is supplied from the outside 118 to prevent from the first blocking position in the first release position. The closure also has a third locking element 146 on. The second actor 144 is to move the third locking element 146 between a third blocking position in which the third blocking element 146 movement of the first locking element 118 prevented, and a third release position in which a movement of the first locking element 118 relative to the third locking element 146 is allowed, trained. The second actuator is used for this purpose 144 laterally to the first locking element 118 in the lock housing 122 arranged. The second actor 144 has a mobility in a direction that is perpendicular to the direction of movement of the first locking element 118 is. The second actor 144 is designed for pressure. The third blocking element engages in the third blocking position 146 in the first locking element 118 and more precisely in a second lateral recess 148 of the first locking element 118 one that of the first recess 142 opposite. There is also a third reset element 150 parallel to the second actuator 144 arranged and with the third locking element 146 connected. The second actor 144 is to move the third locking element 146 into the third blocking position when heat is supplied from the outside. The locking device of the fourth embodiment is thus in comparison to the third embodiment around the third locking element 146 added. This third locking element 146 again contains the second actuator that cannot be energized 144 for pushing in the third locking element 146 into the second recess 148 and the third, passive reset element 150 for pulling out the third locking element 146 . The third reset element 150 , the second actuator 144 and the third locking element 146 are connected to one another in such a way that in the normal state, ie the state at room temperature, the third locking element 146 not the first locking element 118 blocked. As soon as an external heat input occurs at a level that corresponds to the temperature in the closure 106 via the transition temperature of the actuators 112 , 144 increased, the third locking element moves 146 into the second recess 148 of the first locking element 118 . The first actor 112 on the second locking element 140 is also moved and the second locking element 140 moves out of the first locking element 118 out. The first locking element 118 remains due to the blocking by the third locking element 146 so blocked. This prevents the lock from opening unintentionally 106 due to external heat input such as a manipulation attempt by unauthorized persons.

6 shows a sectional view of a locking device 100 according to a fifth embodiment. Only the differences from the locking device are described below 100 described in accordance with the third embodiment and identical or comparable components are provided with the same reference numerals. Note that for the sake of clarity, the power source 110 and the connecting cables 136 are not shown, they are still present in the embodiment shown. In the fifth embodiment, the closure 106 also a second actuator 144 on. The second actor 144 is from the power source 110 Cut. The second actor 144 is designed to move the first locking element when heat is supplied from the outside 118 to prevent from the first blocking position in the first release position. The second actuator is used for this purpose 144 to the antagonistic counteraction of the first actuator 112 as will be described in more detail below. The first actor 112 and the second actuator 144 are arranged parallel to each other and with the second locking element 140 connected. The second actor 144 is designed for pressure. In the fifth embodiment, they are therefore on the second locking element 140 the second reset element above 138 , the energizable first actuator 112 and the second actuator that cannot be powered 144 combined in such a way that the second blocking element in the de-energized state 140 in the first locking element 118 or its first lateral recess 142 protrudes and thus blocks its movement. Becomes the energizable first actuator 112 by an electric current from the power source 110 heated up, the first actuator pulls 112 the second locking element 140 from the first locking element 118 out and releases this. The temperature is increased by an external heat input via the conversion temperatures of the actuators 112 , 144 increases, the force of the second restoring element increases 138 and the second actuator that cannot be energized 144 in total so strong that the first actuator that can be powered 112 is not able to use the second locking element 140 from the first locking element 118 pull out, and the first locking element 118 is thus still blocked.

7th shows a sectional view of a locking device 100 according to a sixth embodiment. Only the differences from the locking device are described below 100 according to the first embodiment and the same or comparable components are provided with the same reference numerals. Note that for the sake of clarity, the power source 110 and the connecting cables 136 are not shown, they are still present in the embodiment shown. In the sixth embodiment, the closure 106 also a second actuator 144 on. The second actor 144 is with the power source 110 connected. The second actor 144 is parallel to the first actuator 112 at the far end 130 of the first locking element 118 arranged. The first actor 112 is designed for pressure and the second actuator 144 is designed for train. This is the second actuator 144 to the antagonistic counteraction of the first actuator 112 educated. The closure 106 furthermore has a locking element 152 on. The locking element 152 is designed as a ball trap or part of a ball trap, ie a ball pretensioned by a spring. The locking element 152 is in the lock housing 122 arranged movable in a direction perpendicular to the direction of movement of the first locking element 118 is. The first locking element 118 defines a first detent position 154 and a second detent position 156 for the locking element 152 . The first rest position 154 and the second detent position 156 are each as dome-shaped recesses laterally in the first locking element 118 educated. The first rest position 154 is closer to the breech counterpart 120 than the second detent position 156 . The locking element 152 engages in the second locking position 156 on, if the first locking element 118 is in the first blocking position. The locking element 152 engages in the first locking position 154 on, if the first locking element 118 is in the first release position. The first actor 112 is to move the first locking element 118 from the first release position to the first blocking position when power is supplied from the power source 110 formed and the second actuator 144 is to move the first locking element 118 from the first blocking position to the first release position when power is supplied from the power source 110 educated. Alternatively, the first actuator 112 on train and the second actuator 144 be designed for pressure. Then the first actor would be 112 when power is supplied from the power source 110 for moving the first locking element 118 formed from the first blocking position into the first release position and the second actuator 114 would be with power supplied from the power source 110 for moving the first locking element 118 formed from the first blocking position to the first release position. Overall, the in 7th embodiment shown realized a bistable mechanism. The locking device 100 the sixth embodiment can thus be both open and closed in the currentless state. Advantage is that container 102 for example, depending on the location, the time or the proximity to the user, can be permanently unlocked even without power consumption. In this variant is the first locking element 118 inside the clasp 106 with the two actuators 112 , 144 connected. The first actor 112 is designed so that it is the first locking element 118 into the lock opening 124 moves into it and thus when the counterpart closure is pushed in 120 locked. The second actor 144 is designed so that it is the first locking element 118 from the lock opening 124 moved out and thus releases the lock. A latching position is assigned to each of the two switching positions, for example through two recesses in the first locking element 118 and a ball trap (ball + compression spring) in the lock 106 can be realized. This locking mechanism ensures that a state (lock 106 locked / unlocked) is held even if both actuators 112 , 144 are currentless.

The 8A to 8G show different views of a locking device 100 according to a seventh embodiment. 8A shows a perspective view of the locking device 100 according to the seventh embodiment in the closed or locked state. 8B shows a perspective view of the locking device 100 according to the seventh embodiment in the open or unlocked state. 8C Figure 13 shows a bottom view of the locking device 100 according to the seventh embodiment in the open or unlocked state. 8D shows an enlarged section of 8C . The 8E shows a perspective view of the closure in a first state. The 8F shows a perspective view of the closure in a second state. The 8G shows a perspective view of the closure in a third state. Only the differences from the locking device are described below 100 according to the first embodiment and the same or comparable components are provided with the same reference numerals.

In the seventh embodiment, the locking device is 100 designed as a snap lock and more precisely as a key lock for a bag. 8A shows the locked locking device, which is similar in appearance to a commercially available pocket lock and how such a lock is to be operated, provided the electronic lock is released. How good in 8A can be seen, the lock counterpart is 120 designed in the form of a buckle, which is attached to the upper part / cover / flap or the like. The closure 106 is designed as a buckle holder, which is attached to the lower part of the bag and contains the actuators. In the form shown the lock contains three independent locking mechanisms, which are described in more detail below. It is explicitly emphasized that the mechanism would of course also work with just one or two of these mechanisms.

As in 8B is clearly visible defines the lock housing 122 a locking slide plane 158 and has on one of the locking counterpart 120 facing end one of the closure sliding plane 158 protruding bracket 160 on. On one of the lock counterpart 120 remote side of the bracket 160 are in the locking sliding plane 158 to the bracket 160 adjoining and side by side a first locking element 118 and a second locking element 140 arranged, which is via a first swivel joint 162 and a second swivel joint 164 each from the locking sliding plane 158 can move out. The first swivel joint 162 and the second swivel joint 164 are each located on a counterpart of the closure 120 facing end of the first locking element 118 and the second locking element 140 . A first reset element 134 , for example, as a spiral spring or leg spring in the first rotary joint 162 is integrated, directs the first locking element 118 in the normal state, i.e. at room temperature, from the slide sliding plane 158 out from. A second reset element 138 , for example as a spiral spring or leg spring in the second swivel joint 164 is integrated, directs the second locking element 140 in the normal state not out of the locking sliding plane 158 as described in more detail below. The lock counterpart 120 has a third locking element 146 on. The third locking element 146 can have a third swivel joint 166 on one of the clasp 106 facing end of the third locking element 146 move out of the plane of the lock counterpart. A third return element steers 150 , for example as a spiral spring or leg spring in the third swivel joint 166 is integrated, the third locking element 146 in the normal state from the plane of the lock counterpart 120 out from. The first locking element 118 , the second locking element 140 and the third locking element 146 are each designed like a switch or rocker switch.

As in 8C can be clearly seen is on the underside of the first locking element 118 the first actuator 112 arranged, which is designed to train so that it is when subjected to a heating current from the power source 110 via two electrical connection cables 136 activated by the control electronics 114 the first blocking element after successful authentication 118 completely into the locking sliding plane 158 can withdraw. As in 8D The first actuator can be clearly seen 112 for example, as from the closure sliding plane 158 out (down) deflected bridge with meandering webs, which contracts when energized in the direction of the flat plane and pulls the first locking element against the spring force into the plane. If the power supply is interrupted, the first reset element swivels 134 the first locking element 118 again out of the locking sliding plane 158 out. On the underside of the second locking element 140 is a de-energized second actuator 144 arranged, which is designed for pressure. The second actor 144 is designed for example as a SMA helical spring. In its normal state, the second reset element presses 138 the second locking element 140 into the locking sliding plane 158 inside.

As in 8C can also be seen, the locking counterpart 120 on its underside one of the first locking element 118 assigned first recess 168 and one of the second locking element 140 associated second recess 170 on. The first recess 168 serves as the first stop 172 and the second depression 170 serves as a second barrier 174 . The coat hanger 160 of the shutter 106 serves as a third barrier 176 . Due to the arrangement of both parts, the locking counterpart 120 under the bracket 160 through along the closure sliding plane 158 in the lock housing 122 are inserted, the first and third locking element 118 , 146 give in briefly. The locking elements 118 , 146 but then snap against the locking stops assigned to them 172 , 176 and prevent the locking counterpart from being pulled out 120 from the lock housing 122 .

In the embodiment shown, the first latching mechanism is from the first locking element 118 , the first actuator 112 , the first swivel joint 162 and the first well 168 or the first barrier 172 of the lock counterpart 120 educated. The second locking mechanism is controlled by the second locking element 140 , the second actuator 144 , the second swivel joint 164 and the second recess 170 or the second barrier 172 of the lock counterpart 120 educated. The second locking mechanism is optional and protects the locking mechanism from unauthorized access. By supplying sufficient heat, for example by means of a hot air dryer, flame, or the like, the first latching mechanism just described can be opened, for example with fraudulent intent, even without electronic authentication. To avoid this, the second, similarly constructed locking mechanism can be integrated. In this case, the second restoring element integrated, for example, into the second swivel joint is used 138 designed so that it is the second locking element in the normal state 140 into the locking sliding plane 158 withdraws. Below the second locking element 140 becomes the second SMA actuator 144 used, but has no electrical connections and thus only reacts to ambient heat. If the locking mechanism overheats, the second actuator presses 144 the second locking element 140 from the locking sliding plane 158 so that a locked buckle is prevented from being pulled out. The third locking mechanism is from the bracket 160 or the third barrier 176 , the third locking element 146 and the third swivel joint 166 formed and is optional. The third locking mechanism ensures that the locking mechanism does not open immediately after it has been electronically unlocked, but must also be unlocked manually. This prevents accidental opening of the bag. This mechanism is very well known from the prior art and is therefore not described in more detail here.

The 8E Figure 3 shows a perspective view of the closure 106 in a first state. In particular shows 8E the "standard" or idle state of the lock 106 or the buckle holder. The first locking element 118 is out of the locking sliding plane 158 deflected out, so that the lock counterpart 120 or a buckle can be pushed in but not pulled out again. The second locking element 140 is in the lock sliding plane 158 withdrawn because the ambient temperature is below the switching temperature Af of the material of the first actuator 112 and second actuator 144 lies.

The 8F Figure 3 shows a perspective view of the closure 106 in a second state. In particular shows 8F the status after successful authentication. The control electronics 114 has the power supply of the first actuator 112 closed, so that the switching temperature Af of the first actuator 112 is exceeded and this is the first locking element 118 into the locking sliding plane 158 withdraws. The second locking element 140 is also in the locking sliding plane 158 withdrawn because the ambient temperature is below the switching temperature Af of the material of the first actuator 112 and second actuator 144 lies. Thus, the buckle, if necessary by manually unlocking the third locking element 146 , if present, from the lock housing 122 or the buckle holder pulled out and the bag opened.

The 8G Figure 3 shows a perspective view of the closure 106 in a third state. In particular shows 8G the condition of the lock housing 122 or the buckle receptacle, if this in its entirety is impermissible due to external heat input above the switching temperature Af of the material of the first actuator 112 and second actuator 144 is heated. The first actor 112 pulls the first locking element due to the heating 118 into the locking sliding plane 158 back, although there is no heating current; ie independent of the control electronics 114 . The second actor 144 however, due to the heating, presses the second locking element at the same time 140 from the locking sliding plane 158 out, preventing the buckle from opening.

9 Figure 3 shows a perspective view of a container 102 with the locking device 100 . At the in 9 The embodiment shown is the container 102 for example designed as a ladies handbag and has the 8A to 8G Shown embodiment of the locking device 100 on. In particular, the women's handbag according to the present invention comprises a buckle receptacle with the first SMA actuator 112 , which is controlled by the control electronics 114 how, for example, an integrated electronics board can be activated. The electronics board also includes the authentication interface 108 such as an RFID-compatible authentication interface or RFID sensor. A bracelet that is fashionably matched to the bag is available as an accessory to the bag 178 with integrated RFID transponder 180 or RFID chip provided. As soon as the wearer with the bracelet 178 comes in close proximity to the bag, this is done via the electronics board or the control electronics 114 registered, whereupon the electronic board the first actuator 112 in the lock 106 energized, so that this the blocking of the lock counterpart 120 solves. The closure 106 can now be opened manually or remain locked / locked. In case of theft / loss, the lock is on 106 however internally by the second actuator 140 or a counter-acting return spring is blocked and cannot be opened manually. For the energy supply of the first actuator 112 and the electronics, the bag contains a power source 110 such as a lightweight, rechargeable Li-ion battery integrated inside the bag. The battery can be charged via the standard USB-C interface 182 can be charged by cable. A second USB port is optionally available inside the bag so that the battery can also be used as a power bank for charging mobile devices. The first actuator is advantageous 112 in the lock 106 bistable, so that the blockage in the lock 106 Can be permanently switched off as long as the bag is close enough to the wearer with the RFID bracelet 178 is located without a constant activation current through the first actuator 112 should flow. Optionally, the electronics board can contain a GPS receiver and can be programmed so that the bag is automatically kept open at certain locations such as home, workplace or the like.

10A Figure 3 shows a top view of a container 102 with the locking device 100 . 10B shows a circuit diagram of the container 102 . 10C shows a perspective view of the Container 102 . In the 10A to 10C The embodiment shown is the container 102 for example designed as a wallet. The locking device 100 can any of the 2 to 8th Shown embodiment of the locking device 100 be. As in 10A shown is the authentication interface 108 designed as a fingerprint sensor or comprises a fingerprint sensor. As in 10B what can be seen is the authentication interface 108 or the fingerprint sensor with the control electronics 114 connected. That in turn with the power source, such as a battery, and the first actuator 112 connected is. The container or purse has an optional inductive charging interface 184 For example, to charge a smartphone or the like or to charge the battery. As in 10C is shown the container 102 or the wallet is opened by a user successfully using a finger on the authentication interface 108 or the fingerprint sensor authenticated, whereupon the locking device 100 like referring to the 2 to 8th described opens or unlocks.

The 11A to 11H show different views of a locking device 100 according to an eighth embodiment. 11A shows a perspective view of the locking device 100 in the locked state. 11B shows a top view of the locking device 100 in the locked state. 11C shows a side view of the locking device 100 in the locked state. 11D FIG. 13 shows a sectional view along the line AA of FIG 11B . 11E FIG. 11 shows a sectional view along the line BB of FIG 11C . 11F shows a perspective view of the locking device 100 in the unlocked state. 11G shows a top view of the locking device 100 in the unlocked state. 11H FIG. 13 shows a sectional view along the line AA of FIG 11G . Only the differences from the locking device are described below 100 according to the first embodiment and the same or comparable components are provided with the same reference numerals.

In the 11A to 11G The embodiment shown is the locking device 100 designed as a so-called twist lock. The closure 106 points inside the lock housing 122 the first locking element 118 on, which is formed essentially pin-shaped. The energizable first actuator 112 and the first return element 134 are with the rear end 130 of the first locking element 118 connected. The first actor 112 is designed for train. The first reset element 134 is designed for pressure. The first locking element 118 can be moved linearly. The lock housing 122 has a protrusion on its top 186 on, which is formed, for example, substantially rectangular or cuboid. The second locking element 140 comprises a substantially rectangular or cuboid lever element 188 , a wave 190 and a disc 192 with a recess or notch 194 . The wave 190 connects the lever element 188 with the disc 192 . The lever element 188 is outside the ledge 186 and is tangible for a user. The wave 190 penetrates the protrusion 186 and extends inside the lock housing 122 . Inside the lock housing 122 is the disc 192 such that the notch 194 from the first locking element 118 can be intervened. The second locking element 140 is relative to the breech housing 122 rotatable. An axis of rotation of the second locking element 140 is determined by the longitudinal direction of the shaft 190 defines and extends through a center point of the protrusion 186 . The lock counterpart 120 has an opening 196 which has a non-rotationally symmetrical shape. For example, the opening is essentially rectangular or cuboid. The size of the opening 196 is dimensioned such that the projection 186 can be received therein or the counterpart closure 120 over the ledge 186 can be pushed.

The functioning of the locking device 100 the eighth embodiment will be described in more detail below. In the locked state of the locking device 100 who is in the 11F to 11H is shown is the breech counterpart 120 over the ledge 186 pushed and the ledge 186 is in the opening 196 recorded. The second locking element 140 is rotated so that the lever element 188 with its longest side edges perpendicular or at least offset to the longest side edges of the projection 186 or the opening 196 extends. The lever elements are accordingly 188 and the opening 196 not congruent, but the lever element is at least one point, such as on two sides, over the opening 196 and thus acts as a stop for the lock counterpart 120 . The lock counterpart 120 can therefore not from the lock housing 122 be moved away. Furthermore, the first locking element 118 from the first reset element 134 into the notch 194 pressed in, so that the first locking element 118 intervenes in this. This results in a rotation of the second locking element 140 blocked.

After successful authentication using the authentication interface 108 becomes the first actuator 112 from the power source 110 energized. This causes the first actuator to pull out 112 together and the first locking element 118 back. The first locking element thus engages 118 no longer in the notch 194 and thus allows manual opening of the Locking device by rotating the second locking element 140 . By the rotation or rotation of the second locking element 140 become the lever element 188 and the opening 196 brought into congruence so that the longest side edges of these are parallel to each other. The lever element thus blocks 188 a movement of the locking counterpart 120 from the breech housing 122 away no more.

It is explicitly emphasized that each of the locking devices described here 100 can be controllable by means of a radio-connected mobile device. For this purpose, the mobile device preferably has an application for controlling the locking device 100 on.
