Description

FIELD OF INVENTION

[0001] The present invention relates to an anti-theft device, and in particular an anti-theft device for a pedal-powered vehicle such as a bicycle. The invention also relates to an electromechanical lock that can be part of the anti-theft device. The electromechanical lock of the anti-theft device can be powered by a mechanical energy harvester. It can be operated by a control unit configured to pair with a user's portable processing device, for example, a multifunction phone with which the user is equipped. The invention therefore also relates to the method of controlling an electromechanical lock. TECHNOLOGICAL BACKGROUND OF THE INVENTION

[0002] Document EP3549849 describes an anti-theft device for a pedal-driven vehicle, such as a bicycle. This device comprises a first locking component designed to be fixed to the ground, featuring a groove or channel for a crank arm. It also includes a second locking component, a removable lock designed to fit over the first locking component, thus clamping the crank arm in place. The second locking component is designed to cover the end of the crank arm and the pedal axle when the crank body is engaged in the groove. This secures the bicycle, preventing it from being moved without first unlocking both locking components.The assembly elements of the crankset are also made inaccessible, particularly at the level of the pedal axle, which therefore does not allow the crankset to be freed by disassembly from the vise formed by the two parts of the lock.

[0003] Although the locking principles outlined in this document are particularly interesting, the proposed solution is not sufficiently comprehensive to form an anti-theft device accessible to a wide public and suitable for operation in an urban environment, for example in a parking station.

[0004] Firstly, the anti-theft device proposed in this document is not adaptable to the size of the bicycle it is intended to secure. To compensate for this, it is necessary to provide, in a parking station, a variety of anti-theft devices, each adapted to a particular bicycle size (from size S to size XL, for example).

[0005] Since the lock isn't always perfectly sized for the bicycle, some of the bicycle's freedom of movement isn't fully restricted, and significant play can occur. For example, the wheels might not be resting on the ground, or they might not be firmly planted. It's then possible to exploit the play between the bicycle and the lock to apply force, effectively pulling the crank arm from the two parts of the lock.

[0006] Furthermore, it is desirable for the anti-theft device to have an interface allowing a user to easily operate the lock, particularly when the device is used in a parking area in an urban environment. This interface could, for example, allow authorization and / or payment for the use of the device. As an illustration, document FR3114431A1 proposes a lock for securing a bicycle to a piece of street furniture. The lock can communicate with a user's portable processing device, i.e., a multifunction phone, and with a remote server. The multifunction phone, the lock, and the server coordinate to authorize the locking and unlocking of the lock. Such an interface requires a power supply for the lock and relatively complex communication capabilities.However, it is generally desirable for the anti-theft device to be as simple, in installation and use, and as robust as possible.

[0007] It should be noted that the issues of interfacing, ease of installation and use, and robustness are not limited to bicycle locks, but can be applied to any lock-based anti-theft device using a lock to secure objects or access to a space, in various fields of application, for example, a lock to secure a key to a dwelling ("key box") or, more generally, a lockbox, or even to lock a gate providing access to an enclosed space. US Patent 9 555 744 B1 shows the preamble to claim 1. SUBJECT OF THE INVENTION

[0014] For the sake of simplicity in the description to follow, the same references are used for identical elements or elements performing the same function in the different modes of implementation of the invention.

[0015] The term "pedal-powered vehicle" refers to any vehicle that can be propelled by its user via a pedal system. This typically includes bicycles, with or without electric assistance, but the anti-theft device described herein is by no means limited to this type of pedal-powered vehicle.

[0016] We recall, in reference to figures 3a and 3bwhich respectively represent a crankset P and a pedal 5, that a crankset P comprises two cranks 2 each having a first end connected to a crank axle 3 and a second end connected to an axle 4 of a pedal 5. The cranks 2 are wedged opposite each other on the crank axle 3. General description of the anti-theft device

[0017] THE figures 1a, 1b , 1c and 1d represent an overview of an embodiment of an anti-theft device 1 for a pedal-driven vehicle, respectively in a free position ( figures 1a , 1c ) and in an occupied or closed position ( figures 1b , 1d) The free position is that of device 1 when it is available to receive a vehicle. The closed position is that of device 1 when it secures a vehicle to prevent theft. The pedal-powered vehicle has not been shown on the [ Fig. 1b ], for better readability.

[0018] The anti-theft device 1 described herein incorporates the principles of the solution presented in document EP3549849 cited in the introduction to this application. Therefore, we find on it the figures 1a, 1b , 1c, 1d A first anti-theft device 6a has a housing 6c designed to receive a crank arm of the vehicle's pedal assembly when it is properly positioned on the anti-theft device 1 for securing. A second anti-theft device 6b is also present, designed to fold over the first anti-theft device 6a to secure it and thus block the crank arm, and more generally, a portion of the pedal assembly is clamped between the two anti-theft devices 6a and 6b.

[0019] More specifically, and in the preferred embodiment represented on the figures 1a, 1b , 1c, 1dThe housing for the first part of the lock 6a is formed by a groove 6c arranged on a front surface of the first part of the lock 6a. The groove is surmounted by a groove 6e to accommodate a pedal axle associated with the crank arm when the latter is positioned in the groove 6c. The groove 6e is thus positioned in the space e separating the crank arm from the pedal, this space e being represented on the [ Fig. 3b The gutter is long enough to extend from the pedal axle 4 to the bottom bracket axle 3 and thus conceal the nut holding the bottom bracket axle to the crank, as can be seen on the [ Fig. 1d This prevents the removal of this nut, which could allow the vehicle to be freed from the vise formed by the two parts of the anti-theft device 6a,6b.

[0020] The first part of the lock 6a also includes a support surface 6h, extending from the groove 6e perpendicularly to the front surface on which the channel 6c is formed. The support surface receives the pedal associated with the crankset when the latter is positioned in the channel. It also prevents access from below to the pedal nut 5a, thus preventing its removal.

[0021] The second locking part 6b consists of a pedal cover plate resting on the support surface. When this plate is folded down over the first part 6a, it prevents access from above to the pedal nut 5a. Advantageously, the cover plate includes a branch 6f to conceal the pedal axle.

[0022] The first and second anti-theft parts 6a, 6b are both supported by a bracket 7, which in the embodiment shown takes the form of a tubular post extending in a substantially vertical longitudinal direction. The first anti-theft part 6a is fixed to the bracket 7. In some cases, the first anti-theft part 6a may be fixed to the bracket, while remaining removable, to facilitate maintenance of the device 1. The second anti-theft part 6b is mounted on a substantially horizontal anti-theft axle 6d, also supported by the bracket 7. The second anti-theft part 6b can be folded down by pivoting onto the first anti-theft part 6a and thus cover it. For this purpose, the second anti-theft part 6b may have a handle 6g allowing the user to grasp this second part and close it over the first part.Of course, support 7 can take a different form than that of the tubular post implemented in the embodiment shown.

[0023] The anti-theft device 1 is equipped with a locking mechanism designed to lock the second part of the anti-theft device 6b onto the first part of the anti-theft device 6a, in order to secure the vehicle and prevent theft. The locking mechanism, also supported by the bracket 7, engages to lock the first and second parts of the anti-theft device together when the second part of the anti-theft device 6b is folded down by the user onto the first part 6a, by rotating it around the axis 6d as will be detailed in a later section of this description. "Locked together" means that it is not possible to separate the second part of the anti-theft device 6a from the first part 6a by applying force to attempt to release the pedal assembly.

[0024] To achieve this, the locking mechanism includes a roller 10 through which the anti-theft axle 6d passes centrally and which is integral with it, so that the pivoting of the second part of the anti-theft 6b causes the roller 10 to rotate. Advantageously, for reasons which will be made apparent in the rest of this description, the roller 10 takes the form of a cam.

[0025] The locking mechanism also includes a lock 24 consisting of a bolt 11 designed to selectively engage and disengage in a locking hole in the roller 10 forming a strike plate of the lock, in order to selectively block and unlock the rotational movement of the anti-theft shaft 6d. When the bolt is engaged in the strike plate, the anti-theft device is locked. The bolt 11 can be moved between its engaged and disengaged positions in the strike plate by any suitable mechanism, for example, and very conventionally, by means of a user-operated key or by means of a motor or servomotor. In the embodiment shown, the bolt 11 is moved by an electromechanical mechanism of the lock, which will be the subject of a later section of this description.

[0026] The anti-theft device 1 also includes an adjustment mechanism for raising the first part of the anti-theft device 6a above the ground. The adjustable height of the anti-theft device 6a, 6b not only allows the device 1 to be adapted to vehicles of different sizes, but also has the advantage of being able, when the device 1 is closed, to press the vehicle firmly against the ground in order to prevent any movement or play in roll, pitch, and yaw. This feature, in addition to the "vise" effect of the two parts of the anti-theft device 6a, 6b which limit movement or play in rolling, swerving, and pitching, helps to secure the vehicle by limiting the torque that can be applied, by forcing the vehicle, to the two parts of the anti-theft device 6a, 6b. This torque aims to separate them and free the vehicle from their grip.

[0027] The adjustment mechanism includes a foot 8 designed to anchor the anti-theft device 1 very firmly to the ground, so that a vehicle held by its crank handle in a vise-like position between the two anti-theft parts 6a, 6b, cannot be easily removed from the device 1. In the embodiment shown, the foot 8 rests on and is firmly fixed to the ground by means of a base that allows, for example, the foot 8 to be bolted to an underground concrete block. However, in alternative or additional embodiments, this foot 8 could be attached to street furniture, an arch, or any other element firmly anchored to the ground. In the embodiment shown, the foot 8 is tubular and is configured to engage with the tubular post 7, allowing the latter to slide and adjust the elevation of the first anti-theft part 6a, which is attached to the tubular post 7, relative to the ground.To allow this sliding, foot 8 extends along a substantially vertical longitudinal direction.

[0028] The adjustment mechanism also includes a piston 9 supporting the bracket 7. The piston 9 can be a simple helical compression spring. The piston allows the bracket 7 and the first part of the anti-theft device 6a, in the open position of the anti-theft device 1 and in the absence of any vehicle, to be positioned at a suitable "reception" height above the ground to accommodate the vehicle. A force with a vertical component directed towards the ground and applied to the bracket 7 tends to compress the spring to adjust the height of this bracket 7 (and the first part of the anti-theft device 6a) closer to the ground. The piston 9 thus allows the height of the first part of the anti-theft device 6a to be easily adjusted to the size of the vehicle, as previously stated, so that the vehicle can rest on the ground once placed in and on the anti-theft device 1.This adjustment of the support elevation, which brings the vehicle to rest on the ground, may require applying additional force beyond that generated by the vehicle's weight alone.

[0029] In the embodiment shown, and as can be seen on the figures 2a And 2b The piston 9 is disposed within the tubular foot 8, with a head 9b of this piston 9 supporting the tubular post 7. More specifically, the head 9b of the piston is in contact with the roller 10 of the locking mechanism. The piston comprises a piston body 9a, a compression spring 9c disposed within the piston body 9a between the piston head 9b, and a second stop 9e located on a rod 9d sliding within the piston body 9a. The rod 9d rests on the base 8a. It is partially inserted into the piston body 9a to retain it and properly position the compression spring 9c, guiding it during compression.

[0030] According to a highly advantageous feature of the anti-theft device 1, the locking mechanism is configured to block the adjustment mechanism when the second anti-theft part 6b is locked onto the first anti-theft part 6a. With the adjustment mechanism blocked, the height of the support 7, and therefore of the first anti-theft part 6a, relative to the ground is fixed. As an example of such a configuration of the locking mechanism and its interaction with the adjustment mechanism, a rack 12 attached to the foot 8 and extending longitudinally within the tubular post 7 can be provided. The locking mechanism itself can be equipped with a notch, for example, a notch formed on the roller 10 carried by the anti-theft axle 6d, which is itself supported by the bracket 7, or a notch carried by a pawl 23 separate from the roller 10.The notch, whether formed on the roller 10 or carried by a ratchet 23, is configured to engage with the rack 12 when the second locking part 6b is folded down onto the first locking part 6a, and the roller is rotated a quarter turn. The cam shape of the roller 10 facilitates the engagement of the notch with the rack 12 during this rotation, selectively engaging the notch when the second locking part 6b covers the first part 6a in the closed position of the locking device 1, and disengaging the notch from the rack 12 when the second locking part 6b is raised to the free position of the locking device 1. When the notch is engaged with the rack, the adjustment mechanism is locked and the sliding movement of the support 7 is no longer possible.In the context of this application, "notch" and "rack" refer to any mechanism configured to cooperate and lock the sliding connection between the support 7 and the foot 8. The notch may thus take the form of any protruding mechanical element capable of engaging in a recess forming a rack. This rack may, in particular, be in the form of a series of holes provided on the foot or on a part integral with the foot, these holes allowing a notch on the support 7 to engage and thus lock the connection.

[0031] Other mechanisms are naturally conceivable for locking the adjustment mechanism in coordination with the locking mechanism. For example, the engagement / disengagement of the notch in the rack, particularly when this notch is carried by a ratchet 23, can be operated by the lock of the locking mechanism, for instance, driven by a key when such a key is used to lock the two anti-theft parts 6a, 6b together, as previously mentioned. An electromechanical lock will be proposed in a later section of this description, allowing the two anti-theft parts 6a, 6b to be locked simultaneously and blocking the adjustment mechanism. In all cases, a locking mechanism conforming to this embodiment is advantageously configured to block the adjustment mechanism when the second anti-theft part 6b is locked onto the first anti-theft part.The elevation of the support 7 and the first part of the lock 6a relative to the ground is fixed in this case. It is particularly advantageous to make the locking of the adjustment mechanism simultaneous with the locking of the two parts of the lock: this prevents the adjustment mechanism from being blocked by the compressed piston spring when the second part of the lock is simply folded down onto the first part 6a, as this simply closed position could release suddenly and injure the user.

[0032] To secure their pedal-powered vehicle, such as a bicycle, a user positions the bicycle in a lock 1 in the free position, with the support 7 and the first part of the lock 6a in the receiving position. To do this, the user places the bicycle's crankset in the device so that one crank arm is wedged in the groove 6c and against the front surface of the first part of the lock 6a. Simultaneously, the user places the pedal against the support surface of this first part 6a. The groove 6e, which is positioned above the groove, is placed in the space e separating the crank arm from the pedal. This positioning, which may require slightly lifting the bicycle from the ground to rest it on the first part of the lock 6a, causes the support 7 to slide downwards. The weight of the bicycle applies a vertical force that tends to compress the spring 9c of the piston 9.The stiffness of this spring is preferably chosen so that, under the effect of an average bicycle weight, the support 7 slides sufficiently and the elevation of the first part of the lock 6a adjusts downwards sufficiently so that the bicycle rests its two wheels on the ground, once properly positioned on the device 1.

[0033] The user can then operate the second part of the lock 6b, for example, by manipulating it by its handle 6g to fold it over the first part 6a, thus clamping it and securing the crankset. The force applied to the second part of the lock 6b by the user is transmitted to the piston 9 via the roller 10, which rests on (and is supported by) the piston head 9b. This effect is amplified by the advantageous cam shape of the roller 10, which requires a greater initial force from the user on the second part of the lock 6b to initiate the rotation of the cam, thereby releasing it from its initial position. This increased force tends to press the bicycle to the ground.It should also be noted that when the second part of the anti-theft device 6b is fully folded down onto the first part 6a and the roller 10 has completed a quarter turn, it reaches a stable position. This means that despite the return force exerted by the piston 9 on the roller 10 of the locking mechanism, the anti-theft device 1 remains fixed in the raised position. Therefore, once the second part of the anti-theft device 6b is fully folded down onto the first part 6a, the user can release the force exerted on this second part 6b without the support 7 rising and without causing the second part of the anti-theft device 6b to pivot open. With the position of the anti-theft device 1 closed and stable, the user can then operate the lock of the locking mechanism, for example, using a key.As already mentioned, the locking mechanism is configured to block the adjustment mechanism, so that in the closed position of the anti-theft device 1, and advantageously only when the lock is engaged, the support 7 cannot slide on the foot 8.

[0034] To release the bicycle from the anti-theft device 1, the user unlocks the second part of the lock 6b from the first part 6a using the lock. Again, this lock can be operated with a key or by any other means, for example, via a multifunction phone, as will be explained in a later section of this description. The user can then apply force to this second part 6b, for example, using the handle 6g. This force tends to pivot this second part of the lock 6b away from the first 6a, placing the anti-theft device 1 in the free position and thus releasing the bicycle. The unlocking of the adjustment mechanism can occur simultaneously with the unlocking step of the lock or, advantageously, to prevent the sudden release of the support 7 pushed back by the piston 9, be triggered by the pivoting of the second part of the lock 6b. Power source for supplying electrical energy to the anti-theft device

[0035] Advantageously, the locking device is an electromechanical lock. In other words, the lock is electrically powered to selectively engage and disengage a distal end 11a of the lock bolt 11 in the locking hole of the roller 10. This selectively blocks and releases the rotation of the anti-theft shaft 6d. The device 1 can then be equipped with a push button allowing the user to lock and unlock the anti-theft device with a simple press of a finger. The push buttons can be in the form of a keypad, allowing the user to enter a lock / unlock code. In this case, the anti-theft device 1 operates in the same way as a lockbox.

[0036] To enable the operation of this electromechanical lock, the anti-theft device 1 must be electrically powered. This can be achieved by connecting the device to an electrical network via a voltage-compensating converter. However, this approach is relatively complex to implement, as it requires such a network to be located near the device 1 and / or significant civil engineering work to connect the device 1 to this network. Therefore, and advantageously, the anti-theft device 1 is equipped with at least one renewable energy source, this source being electrically connected to the electromechanical lock. The source can be connected to other components requiring electrical power from the device 1, as will be explained in a later section. This renewable energy source could include, for example, a solar panel.Advantageously, this source includes a mechanical energy harvester. It is, of course, possible to combine several renewable energy sources, for example, a solar panel combined with a mechanical energy harvester. The energy produced or harvested can be stored in storage devices, such as an electric battery or a capacitor bank. These storage devices may include a voltage regulator capable of supplying a usable DC voltage to the components to which the storage devices are connected.

[0037] For example, the mechanical energy harvester can be connected to the second part of the anti-theft device 6b, in order to recover energy from the rotational movement of this second part 6b when it is folded down onto the first part 6a by the user. In this example, the anti-theft device shaft 6d can be coupled directly, or indirectly via a gear train, to a generator 17, for example, a dynamo. The energy produced by the generator 17 can be stored in the storage device 19 and used by the electromechanical lock.

[0038] Returning to the description of figures 1a,1b , 2a , 2b , 2c We describe a mechanical energy recovery system equipped with the preferred embodiment shown.

[0039] This energy harvester is thus formed by a cap 13 surmounting the top of the support 7. The cap 13 also includes a plate 14 pierced with a longitudinal opening 14a. The plate 14 is integral with the bottom of the cap 13. The plate 14 is positioned relative to the support, here the tubular post 7, when the cap 13 is positioned to cover the top of the support 7.

[0040] The plate 14 is held to the tubular post 7 by means of a return mechanism, here formed of two springs 15 visible on the [ Fig. 2cThe springs 15 have upper ends 15a engaged respectively in transverse pins fixed to the tubular post 7 and lower ends 15b engaged respectively in retaining pins fixed to the plate 14. This arrangement allows the cap 13 to float relative to the tubular post 7: when pressure is applied to the upper part of the cap 14, it slides on the post 7, which tends to extend the springs 15. In this sliding movement, the support 7 enters the inner part of the cap 13. When the pressure applied to the upper part of the cap 14 is released, the springs 15 of the return mechanism tend to return the cap 13 to its original position, and the cap 13 tends to detach from the support 7.The stiffness of the springs 15 is much less than that of the compression spring 9c of the piston 9, so that the pressure applied to the cap 13 tends to preferentially move it on the upper part of the tubular post 7, rather than sliding the tubular post 7 on the foot 8.

[0041] In any event, the cap 13 is capable of moving longitudinally along the post 7 by the application of an external force, and a return mechanism consisting of at least one spring 15 allows the cap 13 to be returned to its original position during a reverse movement when the application of the external force is discontinued. The mechanical energy recovery system can be configured so that the movement, and the reverse movement, can, for example, extend over a distance of approximately ten centimeters.

[0042] The mechanical energy recovery unit also includes a drive mechanism connected to the cap 13 and a generator 17, for converting the movement of the cap 13 into electrical energy. This drive mechanism includes a gear train with a toothed wheel or cylinder 16 engaged in the opening 14a of the plate 14. This opening 14a has a toothed contour, so that the longitudinal movement of the plate drives the toothed wheel or cylinder 16 in rotation. More generally, the gear train can be coupled to a rack carried by the plate 14 of the cap 13. Regardless of the nature of this coupling, the train also includes an end wheel or cylinder that drives in rotation a drive shaft 17a of a generator 17, for example, a dynamo.It is therefore understood that the sliding of the cap 13 on the tubular pole 7 causes the drive shaft 17a of the generator 17 to rotate, via the drive mechanism. The electrical energy produced by the generator 17 can be stored in the storage device 19 to which the generator 17 is connected.

[0043] A user wishing to use the anti-theft device 1, which includes such a mechanical energy harvester, applies force to the top of the cap, for example by maintaining pressure on this top with their hand, in order to cause the cap to slide on the post 7 and generate enough energy to power the lock. This step can be carried out while the anti-theft device 1 is in the free position, before or after installing the bicycle on the first part of the lock 6a, or when the anti-theft device 1 is in the closed position.

[0044] According to a particularly advantageous development, the gear train, or an element of this train such as the toothed wheel or cylinder 16, is freewheeling. Consequently, the shaft 17a of the generator 17 is driven only during the reverse movement of the cap 13 back to its original position, when the user is no longer applying pressure to it. This development is beneficial because it protects the mechanical energy recovery system, and in particular the generator 17 and the toothed wheel 16, from violent forces that the user might apply to the cap and from the energy spikes generated by these violent forces. The reverse movement is well controlled by the return mechanism; it can be carried out at a suitable speed, by controlling the stiffness of the springs 15, to optimize the energy produced and making this energy independent of the intensity of the force applied by the user.The amount of energy produced is therefore made relatively independent of the user. Control unit and method for controlling a lock

[0045] When the anti-theft device is electrically powered, either by a renewable energy source or by being connected to an electrical grid, it is advantageous to equip the anti-theft device 1 with a control unit 18 to automate its operation. Specifically, the control unit 18 can operate the lock, in this case an electromechanical lock, to lock the two anti-theft parts 6a, 6b together and, if necessary, activate the ratchet 23 to lock the adjustment mechanism. This control unit 18 can be remotely operated from a portable processing device held by the user, typically a smartphone, i.e., a multifunction mobile phone.

[0046] It should be noted that the control unit 18 of the electromechanical lock and the method for controlling this lock constitute an aspect of the invention in itself. It can find application in numerous fields, and its use is therefore by no means limited to the anti-theft device 1 for pedal-powered vehicles. For example, this control unit could be used for a key box, the electromechanical lock allowing the distal end of the lock bolt to be placed in a conventional strike plate fitted onto the box. It can be powered by a renewable energy source, such as the energy recovery system described in a previous section. The following description of this control unit and the method for controlling it, however, is given in the context of the anti-theft device 1 described above.

[0047] We have represented on the [ Fig. 4Schematically, such a control unit 18 is associated, in the example shown, with a generator 17 of a mechanical energy recovery system, but could just as easily be associated with an electrical energy source of another kind. This control unit 18 is preferably housed in the support 7 of the anti-theft device 1 to facilitate its electrical connection to the generator 17 and the electromechanical lock. Advantageously, the control unit 20 is positioned as close as possible to the lock, in a secure housing, to limit the risk of break-in. The control unit 18 includes the storage means 19, battery or capacitor, electrically connected to the generator 17, in order to store the energy produced.These storage means deliver this electrical energy to all the components of the control unit 18 in order to power them when a power switch K0 is activated, as will be detailed later in this section of this description. Electrical energy is also delivered from the storage means 19 to the lock via connecting wires (not shown in the figure).

[0048] It should be noted that a mechanical energy recovery system is not likely to provide a large amount of energy, on the order of 1 Joule or a few Joules at most. It is therefore essential that the electrical consumption of the anti-theft device 1 be as low as possible. This electrical energy consumption is only necessary during the locking and unlocking sequences of the device 1. These sequences are generally preceded by the user activating the mechanical energy recovery system by applying pressure to the cap 13, as explained in a previous paragraph, in order to enable the operation of the control unit 18 and the electromechanical lock.

[0049] The control unit 18 includes a controller 20, for example a microcontroller or any other software- or hardware-programmable circuit. The controller 20 is configured to implement the lock control process, in coordination with the user's portable processing device.

[0050] The controller 20 is electrically connected to a communication circuit 21 comprising an antenna 21a. Advantageously, this communication circuit is a passive, short-range NFC (near-field communication) type. It is well known that this type of communication is particularly energy-efficient. The antenna 21a can be arranged in the cap 13, so that the user can, by simply placing their portable processing device on top of this cap 13, electromagnetically couple the antenna of this device to the antenna 21a of the control unit 18.

[0051] Antenna 21a is also connected to controller 20. When the user attempts to connect to control unit 18 via their portable processing device, the device's antenna emits radiation. This radiation is picked up by antenna 21a of control unit 18, and its energy is used to power the communication circuit 21 and controller 20.

[0052] The communication circuit 21 initiates the pairing of the control unit 18 with the user's portable processing device. This pairing, initiated by the portable processing device, establishes communication between this device and the control unit 18.

[0053] The controller 20 is connected to the storage means 19 in order to draw energy from them and to be able to measure their energy level. A power switch K0 is provided here, allowing the controller 20 to connect the control unit 18 to the storage means 19, to power this unit 18 electrically by these means rather than by exploiting the energy captured by the antenna 21a, this energy being necessarily limited.

[0054] The controller 20 is also electrically connected to a plurality of actuators, here an opening switch O and a closing switch C of the electromechanical lock. These switches allow the operation of magnetic actuators, as will be explained in a later section of this description. In such a configuration, which is particularly advantageous in terms of energy consumption, the controller 20 sends a short electrical pulse to one of the magnetic actuators of the lock by briefly toggling the opening or closing switch O, C in order to selectively engage or disengage the distal end of the bolt in the lock strike plate, here the locking hole 10a of the cam-shaped roller 10.

[0055] The control unit 18 may also include or be connected to at least one sensor. In the example shown on the [ Fig. 4This control unit 18 is connected to a first position sensor K1 of the second locking part 6b. This first sensor K1, which can be a simple switch, produces a specific electrical signal when the second locking part 6b is folded down onto the first locking part 6a, i.e., when the locking device 1 is in the occupied position. The control unit 18 is also connected to a second position sensor K2, which detects the engaged or disengaged position of the distal end of the lock bolt. This second sensor K2, which can also be a simple switch, produces a specific signal when the lock bolt 11 is engaged in the locking hole of the roller 10.

[0056] Other elements can, of course, be connected to or included within the control unit 18. In the illustrated example, this unit is connected to an indicator light 22, which is located on the cap 13 of the support 7. This indicator light 22 is controlled by the controller 20 of the control unit 18, and the color of the light is chosen to communicate the status of the anti-theft device 1 to the user. Thus, the absence of light can indicate that the control unit is not active, for example, that the energy storage capacity is depleted. A green light can indicate to the user that the anti-theft device 1 is in the free position and that the energy storage capacity is sufficient. A red light can indicate to the user that the anti-theft device 1 is in the occupied position.A yellow color emission may indicate that the anti-theft device 1 is not functional.

[0057] The user is equipped with their portable processing device. This device runs a computer application designed to interface with the control unit 20 of the anti-theft device 1 in order to control the locking (once the vehicle is properly positioned in / on this device 1) or to control the unlocking of the device 1 to release the vehicle. The locking / unlocking of the anti-theft device 1 must, of course, be secure, i.e., restricted to a single user. The portable processing device therefore emits electromagnetic radiation to establish a communication channel with the control unit 20. Furthermore, the user has previously activated the electrical energy harvester to sufficiently charge the storage device 19, on the order of one Joule or a few Joules.

[0058] The activation of the control unit 18 occurs when the user illuminates its antenna 21a with the electromagnetic radiation emitted by the portable processing device, for example, by positioning the device on the cap 13, as close as possible to the antenna 21a. As previously mentioned, the energy from this radiation is used to power the communication circuit 21 and the controller 20 during this activation phase. During this phase, the communication circuit 21 activates and pairs the control unit 18 with the user's portable processing device. Once this activation phase is complete, the control unit 18 is powered by the radiation received from the user's portable processing device, and the control unit 18 and the portable processing device are able to communicate with each other.

[0059] In this context, we now expose the processing carried out by the controller 20 of the control unit 18, upon its awakening.

[0060] In a first step, the controller 20 checks the energy level of the storage means 19, for example, by measuring the supply voltage provided by these means 19. If it is determined that this energy level does not exceed a predetermined threshold, sufficient to perform a locking or unlocking operation, the controller 20 communicates to the portable processing device that the energy level is too low. The indicator light 22 remains off, indirectly signaling to the user that the anti-theft device 1 is not functioning and prompting them to reactivate the mechanical energy harvester. The controller can repeat this check of the charge level of the storage means 19 after a predetermined waiting time. If this energy level remains insufficient after repeating the check several times, the controller 20 switches off.

[0061] In the event that the level of energy held in the storage means 19 is deemed sufficient during this first stage, greater than or equal to the determined threshold, the controller 20 triggers the switch K0 allowing the control unit 18 to be powered by the storage means 19, rather than by the energy captured by the antenna 21a.

[0062] During one step, the controller checks the status of the anti-theft device 1 by measuring the status of the first and / or second sensor K1, K2. Depending on the status of these sensors K1, K2, and in particular the second sensor K2, the controller 20 activates the indicator light 22 to emit a green or red color, indicating to the user whether the anti-theft device 1 is free or occupied.

[0063] We now consider the case where the user, who has properly placed their vehicle in the anti-theft device 1, wishes to lock it.

[0064] In a third step, the controller 20 checks that the second part of the lock 6b is in the closed position via the first position sensor K1. If it is not, it indicates to the user to put this part of the lock in the closed position via the portable processing device and possibly by a flashing of the indicator light 22.

[0065] In a fourth step, and once the second part of the anti-theft device 6b is in the closed position, the controller 20 sends a unique identification number to the portable processing device via the communication circuit 21. This unique number is received and stored by the portable processing device. The application running on the portable processing device can be expected to process this unique identification number to determine whether the user is authorized to use the anti-theft device 1. This could, for example, involve making a payment or taking a token from a set of available tokens. The portable processing device can contact a remote server to process this payment and / or obtain authorization, but this is not mandatory.In any event, after receiving and storing the unique identification number of the anti-theft device 1, and if the user is authorized to use the device, the user's portable processing device sends a unique locking code to the control unit 18. This unique locking code may have been generated by the portable processing device itself or received from a remote server.

[0066] In a subsequent fifth step of the process implemented by the controller 20 of the control unit 18, the latter receives the unique locking code and stores it, for example in a non-volatile memory of the controller 20.

[0067] Then, in a sixth locking step, the controller 20 sends a pulse to the input / output port connected to the closing contact C of the electromagnetic lock. The lock engages the anti-theft device 1. This locking step may include the actuation of a ratchet 23, which locks the adjustment mechanism, as described in a previous section. This locking step may also include verifying that the lock bolt 11 is properly engaged in the roller hole by measuring the status of the second sensor K2. The indicator light may be activated to emit a red color if the locking is successful, or an orange or flashing light otherwise.

[0068] At the end of the locking step, and when this locking is confirmed by the state of the second sensor K2, the controller 20 can send, in a final confirmation step, via the communication circuit 21, a message to the portable processing device indicating the successful locking of device 1. This transmission can be followed by the unpairing of the control unit 20 from the portable processing device and the putting into standby mode, or even the switching off of the control unit 20.

[0069] We now consider the case where the user wishes to release their vehicle from the anti-theft device 1, it being understood that the first and second steps described previously have been carried out.

[0070] In this context, we reproduce the fourth and fifth steps of receiving and sending the unique identification number and the unique locking code.

[0071] The controller 20 of the control unit 18, which receives the unique locking code, verifies that it matches the code generated and stored when the vehicle was locked in the anti-theft device 1. If it matches, the controller 20 sends a pulse to the input / output port connected to the opening contact O of the electromagnetic lock. The lock then unlocks the anti-theft device 1.

[0072] The control unit 18 of the electromechanical lock and the method for controlling this lock, which have just been presented, are particularly advantageous. The control unit uses the user's portable processing device to contact a remote administration server if necessary. It is not necessary for the control unit to be in direct contact with this server. Advantageously, therefore, an anti-theft device according to the invention lacks any means of communication capable of connecting it directly to a remote server, and thus comprises only a near-field communication circuit. The anti-theft device 1 can therefore remain simple and consume little electrical energy.

[0073] The control unit 18 is activated by the portable processing device, so it does not require a continuous power supply. The control unit's power supply is then switched from this first energy source to the second energy source, which consists of the storage means 19 connected to the renewable energy source. This switchover only occurs if the energy stored in the storage means 19 is sufficient to complete the locking / unlocking operation. Therefore, this unit is only powered during the short locking and unlocking sequences. The energy consumed during each of these sequences can be generated by the user at any time by activating the mechanical energy harvester.In particular, it is not necessary to maintain the power supply to the anti-theft device to keep the electromechanical lock closed, and only the locking and unlocking operations of this lock require a brief electrical pulse to transiently activate the magnetic actuators of the lock. Electromechanical lock

[0074] With reference to figures 5a , 5b , 5c , 6a And 6bWe now present an example of an embodiment of an electromechanical lock for a locking mechanism of the anti-theft device 1. This lock constitutes an aspect of the invention in itself, without necessarily being incorporated into the anti-theft device 1 of the pedal-powered vehicle that is the subject of this description. By way of illustration, this lock can be used in an anti-theft device for a key box. More generally, the lock can be used to secure access to an object held in a locker. It can be used to lock / unlock a gate.

[0075] In general, the lock bolt is intended to engage in a strike plate of a support element, the strike plate of the anti-theft device 1 of a pedal vehicle being formed in the example described in the preceding paragraphs by the opening provided in the roller 10 of the locking mechanism.

[0076] We find on the figures 5a ,5b , 5c , the cam-shaped roller 10 and the ratchet 23. The roller 10 is provided with an orifice 10a, clearly visible on the [ Fig. 5a ], to receive the distal end of the bolt 11. The roller 10 is also provided with a drive pin 10b for driving the pawl 23 when it comes into contact with the pawl stop 23a. The pawl 23 also includes a retaining lug 23c cooperating with a retaining tab 26 to hold the pawl 23 in a position in which the pawl notch 23a is away from and clear of the rack 12 of the adjustment mechanism. The retaining tab 26 is associated with a retaining spring 26a that tends to move it downward towards the pawl 23 to position itself behind the retaining lug 23c. The ratchet 23 is held under tension by a locking spring 32 tending to press the ratchet notch 23b against the rack 12 of the foot 8 when the retaining tab 26 is lifted to disengage from the retaining lug 23c.

[0077] The lock 24 also includes two magnetic actuators 27a, 27b (referred to as "electromagnets" in this field and in the remainder of this description) arranged on either side of the roller 10. Such an actuator comprises a magnetic actuating block and a rod, the actuator being capable of selectively moving a rod in translation between an extended position and an inset position of the rod in the magnetic actuating block. A bistable mechanism disposed between the two electromagnets 27a, 27b carries the lock bolt 11. A bistable mechanism is defined as a mechanism that can assume two stable positions, the switching from one position to the other requiring an input of energy. The activation of a first electromagnet 27a allows the bistable mechanism to switch into a first stable position in which the distal end of the bolt 11 is not engaged in the orifice 10a ([ Fig. 6a]), and the activation of a second electromagnet 27b allows the bistable mechanism to be tilted into a second stable position in which the distal end of the bolt 11 is engaged in the orifice 10a ([ Fig. 6b ]). The electromagnets form the opening or closing switches O,C to which the control unit 18 is connected to selectively activate them.

[0078] With reference to figures 6a , 6bThe bistable mechanism here comprises a rocker arm 28 including a shaft 28c, one end of which is fitted with a guide pin engaged in a groove in a lock support. The rocker arm 28 also includes two arms 28a, 28b, to which the rods 29a, 29b of the electromagnets are respectively retained. The two arms meet at a second end of the shaft 28c, at a collar. The collar has a collar pin 30, around which the rocker arm 28 and the locking bolt 11 are joined, and around which the bistable mechanism can pivot. The bistable mechanism also includes a pivoting spring 31 retained at the first end of the shaft 28c of the rocker arm 28 and at the bolt 11.

[0079] The retaining tab 26 is connected, via a sliding linkage, to the arm 28a of the rocker arm 28, which is coupled to the first electromagnet 27a. The retaining tab 26 is driven upwards when the rocker arm 28 tilts to lock it, thus releasing the pawl 23 to lock the adjustment mechanism. The retaining tab 26 is not driven downwards by the arm 28 when the rocker arm 28 tilts to unlock it. The retaining spring 26a tends to pull the retaining tab 26 back down towards the pawl 23 when the pawl 23 has been disengaged from the rack 12 by raising the second part of the anti-theft device 6b.

[0080] THE figures 6a And 6b show how the activation of either of the two electromagnets 27a,27b allows the bistable element to be positioned in either of these two stable states, that is to say states maintained even when the electromagnets are deactivated.

[0081] There [ Fig. 5a ] shows the state of the lock 24 in the free position of the anti-theft device 1. When the second anti-theft part 6b is moved away from the first part 6a by pivoting, the rotation of the anti-theft shaft 6d, the roller 10, and its pin 10b disengages the ratchet notch 23b from the rack 12 of the adjustment mechanism, the pin 10b coming into contact with the stop 23a and engaging the ratchet 23. This pivoting opening of the second anti-theft part 6b also compresses the locking spring 32 and positions the retaining tab 26 behind the retaining lug 23c. This holds the ratchet 23 in a position where it is not engaged in the rack 12. The adjustment mechanism is released, and the support 7 can slide on the foot 8. We observe on the [ Fig. 5athat, in this free position of the anti-theft device 1a, with the second part of the anti-theft device 6b raised, the orifice 10a of the roller 10 is not positioned opposite the distal end of the lock bolt 11. It is therefore not possible to engage this end in the orifice to lock the device 1.

[0082] There [ Fig. 5b [ ] shows the state of the lock 24 in the closed position of the anti-theft device 1, without the lock 24 having yet been activated. The roller 10 has been moved a quarter turn, to position the opening 10a opposite the distal end of the lock bolt 11. The pawl 23 is still held by the tab 26, and held under tension by the locking spring 32.

[0083] There [ Fig. 5c] shows the state of the lock 24 in the closed position of the anti-theft device 1 and after activation of the lock 24, i.e. after the magnetic locking actuator 27b has been activated by the control unit 18 in order to switch the bistable mechanism according to the configuration of the [ Fig. 6b The distal end of the lock bolt 11 is engaged in the orifice 10a of the roller. By tilting, the bistable mechanism also lifted the retaining tab 26, releasing the ratchet 23 and engaging the notch 23b in the rack of the setting mechanism to lock it.

[0084] An additional mechanism can be provided to lock the bolt 11 in the opening 10a of the roller 10. This additional mechanism aims to prevent the bolt from pivoting, for example, when violent shocks are applied to the support 7 during an attempted break-in, as these shocks tend to cause the bolt to pivot. The additional mechanism can be carried by the retaining tab 26, for example, an extension of this tab 26 covering the lateral face of the opening 10a, so that the distal end of the retaining bolt cannot escape from this opening 10a when the tab is in the raised position.

[0085] Of course the invention is not limited to the implementation methods described and alternative embodiments can be made without departing from the scope of the invention as defined by the claims.
