The present invention relates to a system for the controlled dispensation of cigarettes. In particular, the present invention mostly finds use in the field of systems and devices to limit or gradually quit smoking for a smoker.
It is now widely demonstrated that smoking causes a series of negative effects that can impair health of smokers and people passively suffering their smoking.
Quitting smoking can be very challenging, especially for chronic smokers, which smoke a large number of cigarettes per day (typically more than twenty). There are several methods to inhibit the desire to smoke. Such methods often exploit a pharmacological action adapted to inhibit established receptors. For example by means of chewing gums, plasters etc., the physical dependence on nicotine can be limited. Unfortunately, removing the mental dependence on cigarette is not obtained easily.
By carrying out a test, the Applicant found that most of the smokers, especially the chronic smokers, smoke most of the cigarettes without even noticing it. In particular, by considering a determined number of cigarettes smoked by a sample of smokers, only a very small part of such cigarettes is knowingly smoked, most of the cigarettes are therefore smoked as a not-willed or subconscious action.
Object of the present invention is to provide a system for the controlled dispensation of cigarettes able to limit the number of cigarettes subconsciously smoked by a smoker, and a method for gradually reducing the total number of smoked cigarettes.
These and further objects are achieved by the present invention by means of a system according to claim 1 and the related dependent claims and a method of dispensing cigarettes by means of the aforesaid system according to claim 15 and the related dependent claims.
According to an aspect of the present invention the system comprises a container of the type provided with at least two portions couplable one to another to define at least one containing housing to contain the cigarettes or a pack of cigarettes. The at least two portions are movable between an open arrangement, in which the containing housing can be accessed from the outside of the container, and a closed arrangement in which the containing housing cannot be accessed from the outside of the container. The open arrangement allows a user to insert inside the container a determined number of cigarettes (possibly a whole pack of cigarettes) and/or to pick up at least one cigarette from the container.
According to an aspect of the present invention, the container comprises a clamping device switchable between a locked mode and an unlocked mode. When the clamping device is in locked mode the switching from the closed arrangement to the open arrangement of the container is prevented, whereas when the clamping device is in unlocked mode the switching from the closed arrangement to the open arrangement of the container, and vice versa, is allowed.
The container further comprises a logic control unit configured to drive the switching of the clamping device. The logic control unit is provided with a programmable timer configured to provide at least one dispensation time interval during which the clamping device is enabled to switch to the unlocked mode.
Characteristic aspect of the present invention is that the system comprises a processing device combined with the container and configured to determine the dependence level of a user through the Fagerström test which is a standard tool to evaluate the intensity of the physical dependence on nicotine. Furthermore, the container comprises a first wireless communicating module, the processing device comprises a second wireless communicating module for transceiving data between the logic control unit of the container and the processing device.
The logic control unit is therefore connected to the first wireless communicating module, preferably Bluetooth (for example BLE—Bluetooth Low Energy), for transceiving information between the container and the processing device combined with the container.
The timer is also automatically programmable by means of the processing device according to the dependence level determined through the Fagerström test. Some embodiments can further provide that the user can manually program the timer of the logic control unit by means of the aforesaid processing device (PC, smart phone, tablet, etc.). For example, by means of a program and/or an application (a so called “App”) the user can thus simply and intuitively set the time sequence to enable the clamping device to switch. For example, the user can select a program for gradually reducing the number of cigarettes smoked in a certain period of time or select in which week days to reduce the allowed dispensation of cigarettes. Furthermore, the container can transmit information to the processing device in order to process statistics on the cigarette consumption.
According to a further aspect of the present invention, the container comprises an unlocking button configured to send an unlocking request to the logic control unit. The logic control unit is configured to switch the clamping device to the unlocked mode if the unlocking request occurs during the afore said dispensation time interval.
This way a controlled dispensation of cigarettes is obtained that prevents the smoker from picking up from the container those cigarettes that are usually smoked unwillingly, thus minimizing or at least reducing the total number of smoked cigarettes.
The processing device is preferably combined with the container, to prevent other processing devices from modifying the settings recorded by the user. The combining can be carried out for example by generating an account with a user name and a password related to an unique code (bar code, QR code, etc.) provided with the container. According to a further aspect of the present invention the container comprises sensor means to detect the opening and closing of the container. This way the logic control unit can record the openings of the container therefore computing the number of cigarettes picked up by the user and how many cigarettes remain within the container. Preferably the user can set the typology of brand or the type of cigarettes and the App computes the cost incurred by the smoker in a certain period of time (for example in the last month). Preferably, upon the expiry of the last opening related to the number of cigarettes initially inserted inside the container, the logic control unit keeps the clamping device in unlocked mode to give the possibility of inserting again a cigarette pack (or a determined number of cigarettes) into the container.
Preferably, when the logic unit of the container is connected to the processing device, the container transmits (for example at regular intervals) a log file, i.e. the log of the events recorded by the logic control unit, in which the openings of the container carried out by the user and at which moments (for example date and time) are recorded.
Preferably the container comprises means to detect the presence of a pack of cigarettes inside the container.
Further object of the present invention is a method for the controlled dispensation of cigarettes by means of a system according to any one of the afore mentioned aspects. The method comprises the steps of:
Advantageously, the method further comprises the step of e) recording the openings of said container which are carried out during at least one detection time interval. Preferably, step a) is carried out at least partially through an interface of the processing device. Part of the answers of the Fagerström test are automatically obtained by the processing device depending on the openings recorded during a first detection time interval of step e).
Advantageously, step b) is modified according to the openings recorded during at least one second detection time interval of the step e).
According to a particular aspect of the present invention, the method comprises a step of f) detecting the presence and the absence of a pack of cigarettes inside the container and a step of g) determining the number of openings of the container occurred between the detection of the presence of the pack inside the container and the detection of the absence of the pack inside the container.
Preferably, the method further comprises a step of h) warning the user if the number of openings determined in step g) is lower than twenty.
Further characteristics and advantages of the invention will be more evident from the detailed description of some preferred, but not exclusive, implementations of a container for cigarettes according to the present invention.
Such a description will be herein set forth with reference to the accompanying drawings provided for illustration purposes only and, thus without limitation, in which:
With reference to
In the particular embodiment shown, the container 1 comprises two portions constrained to each other by means of a hinge 7 located on a side common to the two portions 2, 3 (for example on the long side to implement a container openable similarly to a pack of cigarettes).
The two portions 2, 3 are movable between an open arrangement (shown in
The open arrangement allows a user to access the inside of the containing housing 4 in order to pick up for example a cigarette from the container 1. The closed arrangement does not allow the user to access the inside of the containing housing wherein the cigarettes are stored. Preferably, the closed arrangement makes the container airtight, for example by means of gaskets (not shown) arranged at the interface of the portions 2, 3. Further embodiments are however provided in which the container 1 comprises a number of portions 2, 3 larger than two, or in which the at least two portions can be completely separable one from another and couplable by overlapping or interlocking them, or slidingly couplable one to another, or else hinged in different points with respect to the embodiment shown in figures (for example with a hinge arranged on the short side so that the opening of the container 1 is similar to that of the Zippo® lighters).
The couplable portions 2, 3 can define one or more containing housings 4, for example a housing 4 for the cigarettes and a housing (not shown) for a lighter, still falling in the protection scope of the present invention. Generally the container 1 comprises at least two portions 2, 3 couplable one to another to define at least one containing housing 4 for the cigarettes 5 or a pack of cigarettes 6. Preferably, the container 1 comprises a tab (not shown) arranged on the portion 3 of the container 1, by means of which the upper part of the cigarette pack 6 is restrained, in such a way that when the container 1 is brought to the open arrangement, the lid 6a of the pack 6 housed inside the containing housing 4 is opened by means of the tab arranged on the portion 3 of the container 1.
The open arrangement further allows the user to easily insert a certain number of cigarettes 5 or a whole cigarette pack 6 into the containing housing 4.
The container 1 can thus be made of plastic, aluminium, leather, leatherette, etc., depending on the design and the type of coupling made between the portions 2, 3. The container can be made with shapes and size different with respect to those shown in the figures, still falling in the protection scope of the present invention.
In
The clamping device 8, schematically shown in
A first embodiment of the clamping device 8 will be described in greater detail in the following of the present description with reference to
The container 1 further comprises an unlocking button 19 configured to send an unlocking request to the logic control unit 10. The logic control unit 10 is configured to switch the clamping device 8 to the unlocked mode if the unlocking request occurs during the dispensation time interval.
The system 100 further comprises a processing device 15 combined with the container 1. The container comprises a first wireless communicating module 14a, the processing device 15 comprises a second wireless communicating module 14b for transceiving data between the logic control unit 10 and the processing device 15. The timer of the logic control unit 10 is programmable by means of the processing device 15.
In other words, the timer of the logic control unit can be programmed so as to provide one or more dispensation time intervals in which the user is allowed to open the container upon sending an unlocking request. Thus, if the unlocking request is sent during an allowed dispensation time interval, the logic control unit 10 will switch the clamping device 8 to the unlocked mode, otherwise the clamping device 8 will not allow the user to open the container 1 remaining in the unlocked mode.
As it will be described in greater detail in the following of the present description, the time sequence is automatically set by the processing device 15 depending upon the user dependence level determined through the Fagerström test.
An established time sequence set on the processing device 15 is transmitted to the logic control unit 10 by means of the wireless communicating modules 14a, 14b. The set time sequence comprises time intervals in which the unlocking of the clamping device is allowed and time intervals in which the unlocking is not allowed. The logic control unit 10 is therefore provided with a timer (for example a synchronization circuit provided with a quartz oscillator) and a counter by means of which the elapsed time is taken. The clamping device 8 will be enabled to switch to the unlock mode during one or more dispensation time intervals programmed and stored by the logic control unit 10.
The wireless communicating modules 14a, 14b are preferably of the Bluetooth type, more preferably BLE (Bluetooth Low Energy).
The container 1 further comprises means for power supplying 9 all the electric components of the container 1 that are preferably housed inside a containing housing 17 preferably made inside one of the portions 2, 3 of the container 1. For example in the embodiment shown in
Preferably, as shown in
The power supplying means 9 comprise at least one, preferably rechargeable battery, and possibly an inlet 9a preferably with USB (Universal Serial Bus) port with mini A or mini B connectors for the electric power supply from the mains and/or battery recharge. An embodiment is however provided, wherein power supply means 9 comprise batteries of the replaceable “button” type (CR, SR, A, AC, PR).
For example, in the embodiment shown in
In case the container 1 is provided with the afore said inlet 9a for the power supply, the logic control unit 10 of the container 1 can be connected to the processing device 15 also by means of a USB cable.
The user can program the timer of the logic control unit 10 by means of the afore said processing device 15 that can be a PC, a smart phone, a tablet, etc., In particular, by means of a program and/or an application (a so called “App”), the user can simply and intuitively set the time sequence to enable the clamping device 8 to switch.
The sequence is therefore sent by the communication module 14b of the processing device 15 to the communicating module 14a of the container 1 and recorded by the logic control unit 10 of the container 1.
By way of example, the time sequence set can provide that the clamping device 8 is enabled to switch to the unlocked mode a certain number of times within a certain time period (one hour, one day, one week, one month, etc.). Enabling the switching of the clamping device to the unlock mode can be programmed in certain times and/or days, for example by means of an electronic calendar provided by the App.
Once a determined time sequence has been set, the processing device 15 processes the information and generates a code containing the particular time sequence, the latter being time synchronized with date and time of the processing device 15. The sequence is then sent to the communicating module 14a and stored by the logic control unit 10.
Further embodiments are provided in which the user can select an established program for gradually reducing the number of cigarettes smoked in a determined period of time or select in which week days to increase the locking rate of the clamping device. Alternatively, the user can set that the allowed dispensation time interval starts after an established period of time from the last dispensing carried out (i.e. upon the opening the container). In this last case, the container 1 preferably comprises sensor means 16 to detect the opening and closing of the container 1. In the embodiment shown in figures, the means 16 comprise a sensor arranged on the portion 2 to detect the presence of the portion 3 when the container is in closed arrangement.
With reference to
Further embodiments can however provide that the means 16 comprise a micro-switch arranged between the portion 2 and the portion 3 of the container such that when the container is closed the micro-switch is pressed, vice versa when the container is open, the micro-switch is released. The means to determine the opening and closing of the container can comprise photocells, or proximity sensors and similar means known per se in the art for determining the opening and closing of a container. The means 16 are connected to the logic control unit 10 to determine the opening and closing of the container 1.
This way the logic control unit can advantageously count the number of openings of the container therefore computing the number of cigarettes picked up by the user and how many cigarettes remain within the container. Preferably, upon the expiry of the last opening related to the number of cigarettes initially inserted inside the container, the logic control unit keeps the clamping device in unlocked mode to give the possibility of inserting again a cigarette pack (or a determined number of cigarettes) into the container. Preferably, the container 1 comprises means (not shown) to detect the presence of a cigarette pack 6 inside the container 1 (for example at least one proximity sensor on the bottom of the container).
This way, the number of openings of the container 1, occurred between the detection of the presence of the pack 6 inside the container 1 and the detection of the absence of the pack 6 inside the container 1, can be determined. If such a number of openings is lower than twenty, the user is warned by means of a message on the processing device 15 and/or by means of an acoustic signal produced by a speaker of the processing device 15 and/or a speaker 20 provided on the container 1.
The container 1 can transmit information to the processing device by means of the same communicating module 14a in order to process statistics on the cigarette consumption. Preferably the user can set the typology of brand or the type of cigarettes and the App computes the cost incurred by the smoker in a certain period of time (for example in the last month).
When the user changes the time sequence of switching the clamping device in order to reduce the number of smoked cigarettes, the logic control unit makes the changes immediately effective and preferably the App shows the user a “POSITIVE” message, for example: “Good! You are changing your smoking habits, this is good for your health!”. Vice versa, if the change is carried out in order to increase the number of smoked cigarettes (for example by reducing the length and/or the rate of the locked mode of the clamping device), the logic control unit makes such a change effective with a time delay comprised between 12 and 24 hours. In this last case the App preferably shows a “NEGATIVE” message, for example: “Attention! You are changing you smoking habits negatively for your health, are you sure you want to change them? Your change request will be recorded in the next 12-24 hours!”.
Further embodiments can provide that the message shown to the user upon changing the time sequence of switching the clamping device 8 is a voice message emitted by a speaker of the processing device 15 and/or a speaker 20 provided on the container 1.
The App can be able to trace the container 1 by means of the data transmission between the communicating modules 14a and 14b of the container 1 and the processing device 15 respectively, until the container 1 is in the connection range. For example, in case the wireless communicating modules 14a, 14b are of Bluetooth type, the logic control unit 10 can generate an acoustic signal by means of the speaker 20.
Further embodiments can provide that the processing device 15 emits an intermittent acoustic signal (for example a “beep”) whose intermittence frequency varies depending on the power of the signal received by means of the module 14b and sent by the communicating module 14a of the container 1 (as a kind of metal detector).
The container 1 comprises at least one LED 18 connected to the logic control unit to show the locking and/or unlocking of the clamping device 8. Further embodiments can provide further LEDs 18 to show the battery charge status, if the battery is in charge, full charge, etc. An alternative embodiment can further provide that, instead of the LEDs 18 or in addition to the LEDs 18, the container is provided with a liquid crystal display, to show further information such as for example a countdown to reach an allowed dispensation time interval.
In a preferred embodiment, the unlocking button 19 is further configured to send an anti-panic unlocking control to the logic control unit 10. In an alternative embodiment, the anti-panic unlocking control can be sent through the processing device 15 and/or through the unlocking button 19.
The anti-panic unlocking button allows the user to drive the unlocking of the clamping device independently of the unlocking time sequence set on the timer of the logic control unit 10. The logic control unit 10 is therefore configured to switch the clamping device 8 to the unlocked mode upon receiving the anti-panic unlocking control. The anti-panic unlocking control can be acknowledged for example by the logic control unit 10 as a rapid to succession of presses on the unlocking button 19 (for example two presses in five seconds, or five presses in one second) or a prolonged press on the unlocking button (for example a press with length longer than or equal to five seconds, for example 10 seconds). A preferred embodiment can provide that the anti-panic unlocking control and/or the unlocking request can be customized by the user by setting a sort of password made up of a particular succession of presses of the unlocking button having determined frequency and/or duration.
Preferably, the container 1 comprises an impact sensor 21 (for example an accelerometer) able to detect attempts of tampering the container by the user or outsiders. The impact sensor 21 is thus connected with the logic control unit 10 transmitting by means of the communicating module 14a a log file wherein all the events detected of the logic control unit 10 (such as for example the openings in the allowed dispensation time interval, the openings upon requesting anti-panic unlocking, the detected impacts, etc.) are recorded. All the information detected by the logic control unit are sent to the processing device 15, that by means of a local or preferably remote processing program, adapts the unlocking time sequence to the number of openings of the container carried out by the user.
Some embodiments can further provide that the container 1 comprises means to deactivate the first wireless communicating module 14a independently of the logic control unit 10. This way the container 1 can still operate without emitting electromagnetic waves. Such a characteristic is advantageous in case the so called “flight mode” has to be activated for the container 1, i.e. a mode by which the logic control unit 10 is active and the first wireless communicating module 14a is deactivated. For example, the means to deactivate the first wireless communicating module 14a can comprise a switch (preferably accessible to the user from the outer surface of the container) with which the electric connection between the first wireless communicating module and the power supply can be selectively switched.
In brief, by means of the system 100 a method of dispensing cigarettes 5 in a controlled way can be effected, comprising the steps of:
The step d) is carried out if the unlocking request occurs during the dispensation time interval.
Furthermore, the method can comprise the step of e) recording the openings of said container 1 which are carried out during at least one established detection time interval (for example in the last twenty four hours).
The Fagerström test can be carried out at least in part through an interface of the processing device 15.
Preferably, part of the answers of the Fagerström test are automatically obtained by the processing device 15 depending on the openings recorded during a first detection time interval of step e). For example, firstly the container is kept unlocked for a first detection interval in order to record the openings of the container so as to determine the smoker habits and to obtain part of the answers of the Fagerström test.
In a preferred embodiment, the processing device can initially request the user to input data relating to his/her own habits (number of daily smoked cigarettes, times and/or days of high consumption, etc.). In particular, through an interface of the processing device 15, the user can easily answer to a multiple choice point questionnaire in order to compute the user dependence level. The questionnaire corresponds to the Fagerström test, which is a standard tool to evaluate the intensity of the physical dependence on nicotine. The dependence intensity is evaluated in user dependence levels. Each dependence level corresponds to an established range of numerical values. The sum of the answer points is between zero (slight dependence) and ten (very strong dependence). In such embodiments, the time sequence can be automatically set by the processing device 15 depending on these collected data.
The time sequence is set such that the number of cigarettes smoked by the user is gradually reduced depending on the user dependence level. In particular, after a dependence level through the Fagerström test is obtained, the time sequence is set to remove an established number of cigarettes per day according to a particular reduction program.
Preferentially, the reduction program is set depending on the number of cigarettes the smoker smoked on average in one day (obtained for example by the record of the container openings, and the dependence level obtained by the Fagerström test).
For example, in case the number of cigarettes smoked on average in one day by the smoker is lower than or equal to 5, it results that:
In case the number of cigarettes smoked on average in one day by the smoker is between 6 and 8, it results that:
In case the number of cigarettes smoked on average in one day by the smoker is between 9 and 10, it results that:
In case the number of cigarettes smoked on average in one day by the smoker is between 11 and 15, it results that:
In case the number of cigarettes smoked on average in one day by the smoker is between 16 and 20, it results that:
In case the number of cigarettes smoked on average in one day by the smoker is between 21 and 25, it results that:
In case the number of cigarettes smoked on average in one day by the smoker is between 26 and 30, the reduction program provides for removing 4 cigarettes per day per week for the first 3 weeks, then removing 3 cigarettes per week, until complete cessation.
In case the number of cigarettes smoked on average in one day by the smoker is between 31 and 35, the reduction program provides for removing 5 cigarettes per day per week for the first 3 weeks, then removing 3 cigarettes per week, until complete cessation.
In case the number of cigarettes smoked on average in one day by the smoker is between 36 and 40, the reduction program provides for removing 5 cigarettes per day per week for the first 5 weeks, then removing 3 cigarettes per week, until complete cessation.
In case the number of cigarettes smoked on average in one day by the smoker is between 41 and 45, the reduction program provides for removing 5 cigarettes per day per week for the first 6 weeks, then removing 3 cigarettes per week, until complete cessation.
In case the number of cigarettes smoked on average in one day by the smoker is between 46 and 49, the reduction program provides for removing 5 cigarettes per day per week for the first 6 weeks, then removing 4 cigarettes per week, until complete cessation.
In case the number of cigarettes smoked on average in one day by the smoker is between 50 and 54, the reduction program provides for removing 10 cigarettes per day per week for the first 2 weeks, then removing 5 cigarettes per week for two other weeks, then removing 4 cigarettes per week until complete cessation.
In case the number of cigarettes smoked on average in one day by the smoker is between 55 and 60, the reduction program provides for removing 10 cigarettes per day per week for the first 3 weeks, then removing 5 cigarettes per week for two other weeks, then removing 4 cigarettes per week until complete cessation.
In case the number of cigarettes smoked on average in one day by the smoker is larger than 61, the reduction program provides for removing 10 cigarettes per day for the first 4 weeks, then removing 5 cigarettes per day per week for the 2 subsequent weeks, then removing 4 cigarettes per day until complete cessation.
Preferably, the time sequence set in step b) is changed (for example by means of an App) depending on the openings recorded in one or more detection time intervals (for example every twenty four hours or every week) of step e).
For example, if the user carried out a number of openings small with respect to the duration of the dispensation time interval, the time sequence will be adapted so as to reduce the duration of the dispensation time interval and/or the number of dispensation time intervals and/or the number of allowed openings of the container during each dispensation time interval. In this case, sending POSITIVE messages encouraging the user to prosecute the program for reducing the smoking vice can be also provided. In case the user sent the anti-panic unlocking control, then the time sequence will be adapted by increasing the number of allowed openings of the container during each dispensation time interval and/or increasing the duration and/or the number of dispensation time intervals, preferably by shifting them temporally at the moment (week day, time) the anti-panic unlocking control has been used by the user. In the latter case, sending NEGATIVE messages can be provided in order to tempt the user to reduce the number of smoked cigarettes.
The method can comprise a step of f) detecting the presence and the absence of a pack of cigarettes inside the container and a step of g) determining the number of the container openings occurred between the detection of the presence of the pack 6 inside the container and the detection of the absence of the pack 6 inside the container 1.
Preferably, the method comprises a step of h) warning the user if the number of openings determined in step g) is lower than twenty. The user can be warned for example by means of the processing device 15.
Preferably, the method can provide the step of sharing on the Net the performance of the program for reducing the smoking vice. In this case the App (with the user consent) is able to share on social networks (for example Facebook®) messages related to the reduction and the goals reached by the user during the program for reducing the smoking vice carried out by means of the system according to the present invention.
With reference to
Preferably, the clamping device 8 comprises at least one locking element 11 arranged on the portion 2 of the container 1.
The locking device comprises an ending portion 11a adapted to be engaged in a respective seat 13 preferably arranged on the fin 3a of the portion 3 of container 1. With reference to
The clamping device 8 preferably comprises elastic countering means 11b to keep the locking element 11 engaged in the seat 13. In the embodiment shown in
When the container 1 is brought in closed arrangement (from the arrangement shown in
The clamping device 8 further comprises an electric actuator 12 driven by the logic control unit 10 in order to move the locking element with respect to the seat 13. This way the clamping device can be switched between the locked mode and the unlocked mode. Preferably, the electric actuator 12 comprises an electromagnet configured to attract to itself the locking element 11 so that to maintain the clamping device in the unlocked mode.
With reference to
Further embodiments can however provide that the electric actuator 12 comprises for example a piezoelectric actuator or further electrically actuated means, in order to move the locking element with respect to the seat 13.
With reference to
The portion 11a has a slot 24a, the portion 11b has a slot 24b, which are arranged so that to form a slot 24 whose width varies depending on the mutual position of the portions 11a, 11b of the locking element 11. In particular, the portion 11a of the locking element is adapted to be engaged in a seat 13 made on the fin 3a of the portion 3 of the container 1.
With reference to
The clamping device 8 comprises a permanent magnet 22 (symbolically shown with a dotted rectangle) arranged to exert a magnetic force on the locking element 11, and in particular on the portion 11b of the locking element 11, so that to keep the clamping device 8 in locked mode when the locking element 11 is engaged in the seat 13 (as shown in
An end of the portion 11b is subjected to an attractive magnetic force exerted by the permanent magnet 22, the other end of the portion 11b is subjected to an elastic force opposed to the afore said magnetic force, exerted by a spring 23a. The portion 11b of the locking element 11, when the clamping device 8 is in locked mode, is subjected to an attractive magnetic force exerted by the permanent magnet and greater than the elastic force exerted by the spring.
The clamping device 8 comprises an electromagnet 12 arranged to produce a magnetic field adapted to counteract the magnetic field produced by said permanent magnet 22. For example, the electromagnet 12 can be made by winding a coil around the permanent magnet 22 around the magnetic axis (North-South) of the permanent magnet 22. When the electromagnet is activated, the elastic force exerted by the spring 23a becomes higher than the resulting magnetic force acting from the permanent magnet 22 and the electromagnet 22. This way the portion 11b is shifted together with the portion 11a of the locking element that is disengaged from the seat 13 of the fin 3a (as shown in
In the arrangement shown in
With reference to
When the fin 3a is completely released from the slot 24, the second expanding spring 23b displaces the portion 11a of the locking element with respect to the portion 11b (that is restrained by the permanent magnet) so that to reduce the width of the slot 24. In this arrangement shown in
When the fin 3a is inserted again inside the slot 24, the cam portion 25 acts on the portion 11a that is displaced so that to increase the width of the slot 24, to allow the fin 3a to be passed through the slot 24. When the seat 13 of the fin is aligned to the portion 11a of the locking element (as shown in
