THEFT PROTECTION ORDER

Description

[0001] The invention relates to an anti-theft device for a bicycle, in particular for a bicycle in a bicycle rental system.

[0002] Various solutions for securing bicycles against theft are known from the state of the art.

[0003] One type of frame lock is attached to the bicycle frame and blocks the wheel's rotation when locked. The disadvantage is that bicycles locked in this way can still be carried away.

[0004] Another solution is to prevent theft by locking the bicycle to fixed objects such as street signs or lampposts with a clip, cable, or chain lock. Professional bicycle rental systems also use special fixed bicycle racks that serve as stations, capable of locking bicycles and releasing them to authorized users.

[0005] EP 2 090 501 A1 describes a bicycle locking system consisting of a bicycle station and at least one bicycle, in which docking means are provided for locking the bicycle to the bicycle station. The bicycle station has a user communication terminal for authentication and for controlling the docking means. This document discloses the features of the preamble of claim 1. .

[0006] According to EP 2 332 811 A1, a securing device for a bicycle is proposed in such a way that a bicycle support can be locked in a support position and prevents the bicycle from being used in this position.

[0007] Furthermore, KR 2011 0083 763 A describes a device and a method for parking a bicycle using a secondary locking device that is attached to the bicycle to be returned in order to facilitate the return.

[0008] Furthermore, TW M 553 854 U describes a bicycle rental system in which the bicycle is equipped with a control device and a frame lock body that provides for coupling to a fixed parking column.

[0009] The object of the invention is to provide an arrangement that enables theft-proof storage of bicycles, excludes unauthorized use, is easy to operate and resistant to malfunctions, can be integrated into a bicycle rental system and can be provided cost-effectively.

[0010] The problem is solved by the features listed in claim 1. Preferred embodiments are set forth in the dependent claims.

[0011] According to the invention, the anti-theft device comprises a bicycle, a stationary bicycle stand and a coupling actuation unit.

[0012] According to the invention, the bicycle has a control unit, a frame lock and a bicycle-side coupling section.

[0013] According to the invention, the control unit includes an authentication module.

[0014] According to the invention, the control unit is designed to authenticate a user and generate a security status control command.

[0015] The authentication module has the function of recognizing an authorized user and distinguishing them from an unauthorized user. The structural design of the authentication module can vary depending on the authentication method.

[0016] Preferably, the procedure is designed such that the user stores data with a central authority, authorizing them to use the bicycle. This central authority is preferably a server accessible via the internet and telephone. The central authority then issues a code, which the user transmits to the authentication module of the control unit.

[0017] This could be, for example, a simple numerical or alphabetical code, or any other string of characters, which the user enters directly on the bicycle, for instance, into a keypad or touchscreen connected to the authentication module. After entry, the authentication module communicates with the central unit and checks the validity of the code. If the code is valid, authentication is successful.

[0018] However, the code can also be output electronically to a data carrier, which then transmits this code electronically to the authentication module.

[0019] Such a data carrier can be, for example, an RFID chip, an electronic key, a USB stick, or a smartphone. After receiving the code, the authentication module preferably communicates with the central authority to compare the data associated with the code. Data comparison can also be performed directly with the information stored on the device. When using a smartphone as a data carrier, data can be exchanged via the display, for example, using barcodes or QR codes, or via a direct data connection such as Bluetooth, NFC, or similar technologies. For this purpose, the authentication module is equipped with a suitable scanner (e.g., a camera or laser scanner) or a compatible data interface capable of reading or receiving the data.

[0020] Preferably, the authentication module can access the hardware of the user's smartphone, such as the camera, fingerprint scanner, and internal serial numbers, via a suitable program, for example, a downloadable app, and use this for additional user identification.

[0021] In another version, the authentication module is paired with a scanner that can identify the user, for example, via biometric data. A camera on a bicycle could, for instance, perform face and eye recognition, or a fingerprint scanner could recognize a fingerprint. In this version, if the biometric data is successfully matched, the user is considered authenticated.

[0022] Upon successful completion of the authentication process, authentication is complete and the control unit generates a security status control command.

[0023] The security status control command can be in the form of either a locking or unlocking instruction. A locking instruction, hereinafter also referred to as a locking command, is directed either to locking the frame lock (in this case also referred to as a locking command) or to coupling the coupling unit (in this case also referred to as a coupling command). The locking command can also be in the form of both a locking command and a coupling command simultaneously. A unlocking instruction, hereinafter also referred to as an unlocking command, is directed either to unlocking the frame lock (in this case also referred to as an unlocking command) or to decoupling the coupling unit (in this case also referred to as a decoupling command). The unlocking command can also be in the form of both an unlocking command and a decoupling command simultaneously.

[0024] According to the invention, the frame lock comprises a frame lock connection module as well as a drive and locking element.

[0025] The frame lock connection module is designed according to the invention to receive the security status control command and to generate a positioning command from the security status control command.

[0026] For this purpose, the frame lock connection module is connected to the control unit and preferably receives the security status control command via cable.

[0027] According to the invention, the drive is connected to the frame lock connection module and is designed to receive the positioning command and to mechanically actuate the locking element.

[0028] The frame lock connection module generates a corresponding actuation command for the drive from the security status control command. This command is preferably transmitted via a wired connection to the frame lock connection module. The frame lock connection module is an electrical or electronic circuit. The frame lock connection module and the drive can also be designed as a single assembly. In particular, the frame lock connection module can be integrated into an electronic or electrical circuit within the drive.

[0029] According to the invention, a locking state can be produced with the locking element and can be released to an unlocking state.

[0030] Based on the actuation command, the drive mechanically moves the locking element into a locked position or vice versa from the locked position to an unlocked position.

[0031] According to the invention, the bicycle cannot be ridden in the locked state.

[0032] In the locked state, the locking element has a position which blocks driving operation, preferably by locking the wheels from rotating.

[0033] The bicycle has a coupling section on the bicycle side. This coupling section is designed to be coupled to a coupling section on the stand side. The stand-side coupling section and the bicycle-side coupling section are collectively referred to as the coupling unit.

[0034] The bicycle-side coupling section features mechanically stable molded sections such as recesses, guides, or bores, which can at least partially accommodate the stand-side coupling section. Conversely, a design is also possible in which the bicycle-side coupling section is accommodated within the stand-side coupling section, thus creating a positive-locking connection between the two coupling sections.

[0035] The stationary bicycle rack features a coupling section on the rack side. This section is designed to be positively coupled to the coupling section on the bicycle side. Depending on the design of the bicycle-side coupling section, the rack-side coupling section may have mechanically stable features such as recesses, guides, or bores that can at least partially accommodate the bicycle-side coupling section. As already described in connection with the bicycle-side coupling section, a design is also possible in which, conversely, the rack-side coupling section is accommodated within the bicycle-side coupling section, thus creating a positive-locking connection between the two coupling sections.

[0036] The third main component of the arrangement according to the invention is the coupling actuation unit. According to the invention, the coupling actuation unit comprises a coupling actuation connection module as well as an actuator and a locking element.

[0037] The coupling actuation connection module is designed according to the invention to receive the safety state control command and to generate an actuation command from the safety state control command.

[0038] The coupling actuator connection module is connected to the control unit directly or indirectly via another component. The connection is preferably wired. The coupling actuator connection module is an electrical or electronic circuit.

[0039] According to the invention, the actuator is connected to the coupling actuation connection module and is designed to receive the actuation command and to mechanically actuate the locking element.

[0040] The actuator is preferably connected to the coupling control module via a cable and receives the actuation command from it.

[0041] Upon receiving the actuation command, the actuator activates the locking element. The actuator is preferably electrically driven and switched. In one embodiment, the actuator is, for example, an electric motor that moves a locking element designed as a rack via a pinion.

[0042] Another possible design consists of an electromagnet which moves a bolt-like locking element between two positions, a locked position and an unlocked position.

[0043] The locking element is preferably designed as a bolt which, in a coupled state, is inserted into the bicycle-side coupling section. The bolt can be straight or bent. A straight design is particularly advantageous for short lengths, as it is cost-effective and can be produced in large quantities. A bent design is advantageous when space is limited and the bolt length is long.

[0044] The design of the actuator and the locking element is not limited to the possible designs described as examples.

[0045] According to the invention, the locking element allows a coupling state to be established with the bicycle-side coupling section and a decoupling state to be released. In the coupling state, there is a positive fit between the bicycle-side and stand-side coupling sections, so that the bicycle cannot be removed from the bicycle stand. When the locking element is moved to an unlocked position, the positive fit and thus the coupling state are released. The decoupling state is now present, in which the bicycle can be removed from the bicycle stand by the user.

[0046] The coupling control unit can be structurally integrated either with the bicycle or with the stationary bicycle rack. Alternatively, the coupling control unit can also be structurally distributed between the bicycle and the stationary bicycle rack.

[0047] According to the invention, two fuses are provided in parallel with the control unit.

[0048] Firstly, the security status control command, acting as a locking or unlocking command, provides a control command for the actuator on the frame lock side via the frame lock connection module, which brings about a locked or unlocked state. Secondly, the security status command, acting as a coupling or decoupling command, generates an actuation command for the actuator on the coupling unit side via the coupling actuation connection module, which brings about a coupled or decoupling state.

[0049] Thus, locking command and coupling command, unlocking command and decoupling command, frame lock connection module and coupling actuation connection module, positioning command and actuation command, positioning element and actuator, locking element and locking element, locking state and coupling state, as well as unlocking state and decoupling state are each parallel categories.

[0050] The anti-theft device according to the invention has, in particular, the advantages described below.

[0051] The anti-theft device according to the invention provides a solution that enables, in a particularly simple and user-friendly manner, an alternative or cumulative securing of the bicycle by locking the bicycle using the frame lock and by connecting the bicycle using the coupling unit together with the coupling actuation module.

[0052] The anti-theft device advantageously allows the bicycle to make the decision to lock and secure the bike, or vice versa, to unlock it. Even when locked to a stationary bike rack, the decision to connect or disconnect is made solely by the bicycle. This allows the bike rack to be designed without its own intelligence, i.e., without an intelligent control unit or authentication module. Furthermore, it is not necessary for the bike rack to communicate with a central entity, such as a server. In a further development phase, it is even possible to design the bike rack without its own power supply. This makes such a bike rack very cost-effective and requires minimal ongoing monitoring and operating costs.Despite this structural and functional relief of the bicycle rack, it remains possible to lock the bicycle securely in place. Furthermore, the positive locking mechanism of the coupling unit allows for a particularly high level of security, far exceeding that of conventional bicycle locks such as cable, chain, folding, or U-locks.

[0053] Furthermore, it is advantageous that the anti-theft device according to the invention can be integrated into a centrally controlled bicycle rental system. It is particularly advantageous that such a centrally controlled bicycle rental system can be designed as either a station-based system or a hybrid system. In a station-based system, the bicycles are always locked to fixed bicycle racks of the rental system for return and collection. In a hybrid system, return and collection can also take place at other locations without fixed bicycle racks. This is made possible by the additional security option provided by the frame lock.

[0054] According to an advantageous further development, the frame lock is designed to establish a locking state by manual operation and to generate a security state control command with which a coupling state can be established.

[0055] In this advanced version, the frame lock can be brought into a locked state not only by means of a security status control command generated by the control unit and transmitted via the frame lock connection module and the drive to the locking element. Rather, the locked state can also be achieved by manual operation, for example, by manually positioning the locking element. This manual operation can act directly on the locking element. Alternatively, a supporting mechanical or electromechanical device can be provided.

[0056] Furthermore, according to this advanced training, the locking process generates the security status control command. This can be done, for example, directly by the frame lock connection module, an additional electronic or electrical circuit, or by the control unit receiving a signal from the frame lock, whereupon the control unit generates the security status control command. As a coupling command, the security status control command causes an actuation command to be generated via the coupling actuation connection module, which then establishes a coupling state. This coupling state secures the bicycle to the stationary bicycle rack.

[0057] The security status control command triggered by manual operation is a locking command, not an unlocking command. This makes it possible to lock the bicycle without authentication and simultaneously secure it to the fixed bicycle rack. However, it is not possible to unlock the bicycle and detach it from the fixed bicycle rack without authentication. This ensures straightforward theft protection, even in the event of communication disruptions with the central system and without requiring registration.

[0058] The advantage of the further training lies in the fact that by manually operating the frame lock, both locking and coupling with the stationary bicycle stand is simultaneously achieved.

[0059] According to a further advantageous development, the anti-theft device has an interface consisting of a bicycle-side and a stand-side interface section.

[0060] The bicycle has a bicycle-side interface section which is connected to the control unit and is designed to transmit a safety status control command.

[0061] According to an advantageous embodiment, the stationary bicycle rack has a rack-side interface section configured to receive a safety status control command from the bicycle-side interface section. The rack-side interface section is designed as a corresponding counterpart to the bicycle-side interface section.

[0062] The two interface sections are designed to transmit the safety status control command from the bicycle to the stationary bicycle rack. In a simple embodiment, the interface can be configured using electrical touch contacts. When the bicycle is placed in the stationary bicycle rack and positioned in the desired position by guide elements, physical contact is established between the touch contacts of the two interface sections.

[0063] For example, by hanging or placing the bicycle on a rail, its weight can be used to determine its position using guide elements and to establish physical contact between the touch contacts of the two interface sections using a lever arrangement.

[0064] Preferably, the interface can also be designed to enable wireless transmission. This can be implemented as simple inductive transmission or, for example, as an NFC connection.

[0065] According to this further advantageous development, the coupling actuation unit is arranged on the stationary bicycle stand and connected to the stand-side interface section.

[0066] The coupling actuation unit is attached to the stationary bicycle stand and connected to the stand-side interface section in such a way that it can establish the coupling state after receiving the safety state control command.

[0067] The advantage of arranging the coupling actuation unit on the stationary bicycle stand is a saving of weight on the bicycle as well as a prevention of an unfavorable mass distribution, for example on the front fork).

[0068] The structural distribution of the components of the arrangement, on the one hand on the bicycle and on the other hand on the bicycle rack, enables a division of functions between the bicycle and the bicycle rack according to the master-slave principle. Here, the bicycle acts as the master and the bicycle rack as the slave. The decision to lock or unlock is thus determined on the bicycle side. This decision is then actively executed by the bicycle rack.

[0069] A particular advantage of this training is that the bicycle can be trained to be locked to the stationary bicycle rack without its own locking mechanism, making it lighter, less prone to malfunctions and more cost-effective.

[0070] According to an advantageous further development, the bicycle has an electrical energy source which supplies the actuator with the energy for its operation via a contact point on the bicycle side and on the stand side.

[0071] The electrical power source is preferably a battery integrated into the bicycle. This can also be a battery already present in an e-bike. The battery can be recharged via an external power supply or while riding, for example, using a hub dynamo.

[0072] According to this further development, the electrical power source is also connected to the bicycle-side contact point via a cable. The cable is designed to transmit an electric current from the electrical power source to the bicycle-side contact point.

[0073] The contact point on the stand side is connected to the actuator. The contact point on the stand side is also electrically connected to the actuator via a cable.

[0074] The bicycle-side contact point and the stand-side contact point are collectively referred to as the contact points.

[0075] The contact points are designed to transmit electrical energy when the bicycle-side coupling section is positioned against the stand-side coupling section. The stand-side contact point forms the corresponding counterpart to the bicycle-side contact point.

[0076] Placing the bicycle in the stationary bicycle rack creates an electrical connection between the two contact points. This connection enables the transfer of electrical energy.

[0077] It is designed with direct contact or without contact. Direct contact can be provided similarly to the connection of the two interface sections by means of touch contacts, whereby the reliable contact can be supported by a mechanical lever arrangement which presses conductive areas of the touch contacts together through a simple mechanism.

[0078] The contact points can also be designed for contactless transmission, for example inductive or capacitive.

[0079] The advantage of this advanced training is that the stationary bicycle rack does not require its own power supply. It can therefore have a simple and cost-effective design.

[0080] According to another advantageous further development, the anti-theft device has a data connection between the bicycle stand and the bicycle and is designed to transmit bicycle stand data to the control unit.

[0081] Bicycle rack data can include, in particular, a bicycle rack identification code, data on the location of the bicycle rack, data on the coupling status, data on the operational capability, or data on the frequency of use of the bicycle rack.

[0082] In this advanced training, the interfaces are additionally trained, after a connection has been established, to transmit data from the stand-side interface section to the bicycle-side interface section and to the control unit.

[0083] This allows bicycle rack data to be transmitted from the bicycle rack to the control unit and from there to the central location. Advantageously, the stationary bicycle rack itself does not need to be capable of communicating with the central location.

[0084] In a further advantageous development, the stationary bicycle stand features a coupling status sensor.

[0085] The coupling state sensor allows a coupling state to be detected and transmitted.

[0086] The coupling state sensor determines whether a coupling state or a decoupling state exists. The coupling state sensor then makes the determined coupling state of the coupling sections available for transmission.

[0087] In one variant, it transmits the coupling state to the evaluation unit. This advantageously facilitates error-free actuation of the locking element of the stator-side coupling section. In particular, the evaluation unit can thus recognize whether an actuation command generated on the basis of a coupling state control error has been correctly executed by the actuator and whether the locking element is in the correct position.

[0088] Preferably, the coupling state is transmitted to the control unit, either additionally or exclusively. This transmission preferably occurs via the data interface. However, other transmission methods are also possible. The control unit can then remotely transmit the coupling state to a central location, such as a server.

[0089] For example, when a bicycle is parked in a fixed bicycle rack, its connection status can be transmitted to the central system. This connection status information can preferably also be linked to a bicycle rack identification code. The central system can then use this data to calculate the utilization and frequency of different locations. Furthermore, the location of a bicycle can be verified, as the location of the relevant fixed bicycle rack is stored at the central system. This also provides a database for optimizing the locations of bicycle racks. A particular advantage is that data on bicycle rack occupancy is available in real time, even though the bicycle racks themselves have no means of communicating with the central system.

[0090] The invention is described as an embodiment by reference to Fig. 1 Anti-theft device (side view) Fig. 2 Detail view of handlebar fork with stationary bicycle stand (coupling state) Fig. 3 Detail view of frame lock Fig. 4 Detail view of bicycle-side version explained in more detail.

[0091] The Figure 1 shows an exemplary embodiment of the anti-theft device in a side view.

[0092] The bicycle 1 has a control unit 4 with authentication module 7, a frame lock 5, a bicycle-side coupling section 6, a bicycle-side interface section 15 and an electrical power source 17.

[0093] In this version, the bicycle-side interface section 15 and the bicycle-side coupling section 6 are located on the front fork of the bicycle 1.

[0094] The stationary bicycle stand 2 is equipped with the stand-side coupling section 11, the coupling actuation unit 3 and the stand-side interface section 16.

[0095] The coupling actuation unit 3 includes the coupling actuation connection module 12. The two coupling sections 6, 11 and the interface sections 15, 16 are arranged so that they are aligned with each other when the bicycle 1 is placed in the stationary bicycle stand 2.

[0096] In the Figure 2 The bicycle 1 is shown in a secured state in the stationary bicycle rack 2. In the shown secured state, the frame lock is in a locked position and also in a coupled position.

[0097] In the embodiment according to Figure 2The coupling section 11 on the stand side has a T-slot-shaped molded section. The T-slot section extends essentially horizontally and has a limit. The coupling section 5 on the bicycle side has a corresponding mushroom-shaped molded body, allowing the bicycle to be driven forward into the stationary bicycle stand 2, with the mushroom-shaped molded body being inserted into the T-slot section up to the limit. The undercuts of the T-slot provide a positive locking mechanism to prevent the mushroom-shaped molded body from being pulled out laterally.

[0098] Since a connection exists between the control unit 4 and the evaluation unit 9 via interface sections 15 and 16, a coupling command from the control unit 4 can be transmitted to the coupling actuation connection module 12, which then provides an actuation command for the actuator 13. In accordance with the actuation command, the actuator 13 extends the locking element 14, which in this embodiment is designed as a movable bolt. The locking element 14 is extended behind the mushroom-shaped body in the direction of entry, so that the mushroom-shaped body is now enclosed and can no longer be moved out of the T-slot in the opposite direction of entry. This creates a positive connection between the stand-side coupling section 11 and the bicycle-side coupling section 6, so that the bicycle 1 is reliably connected to the stationary bicycle stand 2 and thus protected against theft.Actuator 13 has an electromechanical drive. The electrical energy is supplied by the electrical energy source 17, which is a battery, located in the bicycle 1. Actuator 13 is connected to the electrical energy source 17 via contact points 18 and 19.

[0099] When an authorized user authenticates via the authentication module 7, the control unit 4 generates a unlock command, which is transmitted as a decoupling command to the coupling actuation connection module 12. The coupling actuation connection module 12 then generates an actuation command to the actuator 13, which electromechanically retracts the locking element 14. This clears the path for the mushroom-shaped body in the opposite direction of entry, and the bicycle can be reversed out of the bicycle rack 2. At the same time, the unlock command is transmitted as an unlock command to the actuator 13. Figure 2The frame lock (not shown) is transmitted. This puts the frame lock into the unlocked state. The bicycle 1 is now neither connected nor locked and is available for the authorized user. The coupling status sensor 20 detects whether the bicycle 1 is connected or not based on the position of the locking element 14.

[0100] Figure 3 Figure 1 shows a detailed view of the frame lock 5 in the locked position. In this configuration, the frame lock 5 is located on the rear wheel of the bicycle 1. The frame lock 5 includes the frame lock connection module 8, the drive element 9, and the locking element 10.

[0101] When the frame lock connection module 8 receives the security status control command, it generates the actuation command to actuate the locking element 10 and sends it to the drive element 9.

[0102] The drive element 9 then moves the locking element 10 into the spoke space, thus establishing the locking state.

[0103] Figure 4 Shows a detailed view of a bicycle-side version of the anti-theft device in the coupled state. Compared to the embodiment shown in Figure 2 All the electronics are mounted on the side of the bicycle.

[0104] In this embodiment, the stand-side coupling section 11 on the stationary bicycle stand 2 is designed as a bore in the stand-side coupling section 11. The bore accommodates a bolt for establishing a coupling state; in this embodiment, the bolt is a component that structurally integrates the locking element 14 and the bicycle-side coupling section.

[0105] The coupling actuation unit 3 is duplicated and includes the coupling actuation connection module 12, the coupling status sensor 20, the actuator 13, and the locking element 14. The coupling actuation unit 3 is integrated here into the bicycle-side coupling section 6.

[0106] The actuators 13 are connected to the electrical power source 17, and the coupling actuator modules 12 are connected to the control unit 4. The control unit 4 includes the authentication module 7 for user authentication.

[0107] To decouple, the actuators 13 move the locking elements 14 into a hollow wheel hub, thereby releasing the bicycle. Reference symbols used
