- the present indicator may also comprise an additional display 19 of conventional type, connected to the microprocessor 11 and arranged within the car at a position visible by the car's driver, for signalling to him both the starting and end time of each parking and the time during the day.
- Such an additional display 19 signals permanently the daily time and in case also the days and the months of each year and is activated by the microprocessor 11 in the manner hereinafter described, for signalling the starting and end parking time of the car too, which signalling is displayed also on the remaining display 12.
- the pulse shaping circuit 13 is connected to at least a mechanical vibrations sensor 20 of per se known type, fitted inside the car and sensitive to the vibrations produced by the engine and transmitted to the entire motor-vehicle.
- Such sensor in particular, is so realized as to generate an electric pulse only when the vibrations determined by the motor-vehicle engine movement have gone out as soon as such engine is stopped, and to transmit such pulse to the pulse shaping circuit 13, which thus is activated by generating in turn the electric pulses for the operation of the parking time indicator.

- In this way, when the motor-vehicle engine is stopped, the switch is turned on by actuating the ignition lock key or a vibration switch acting as vibration sensor and operated in absence of engine vibrations, so that such switch energizes the driving means which in turn cause the disc to rotate and therefore the parking time indication to be started and signalled in the indicator.
- From EP-A-0297531 is known a parking time indicator for motor-vehicles, which may be fitted at an externally visible position in the interior of the motor-vehicles, comprising a remote control with a receiver arranged inside the motor-vehicle and provided with an electronic digital clock for the parking time, a display for displaying the parking time indication, and controls for regulating the time, and a transmitter communicating with the receiver by means of radiofrequency, supersonic or infrared systems, which is provided with an electronic digital minute-counter, a display for displaying the parking time indication and controls for starting and ending the parking time indication on the receiver, said receiver and transmitter being both powered by an associated battery.
- The receiver comprises a receiver circuit connected to a microprocessor and pilot control circuits for parking time indication, through the electronic digital clock, and for other functions. The transmitter comprises a microprocessor connected to the electronic minute-counter and the controls, so as to select the parking time duration, which is displayed by the associated display, and also comprises a coding modulator and a transmitter circuit, in order to transmit the informations corresponding to the selected parking time duration as well as the starting of such parking time to the receiver, which in turn is activated and provides for displaying such parking time indication on its display.
- The present invention discloses a parking time indicator for motor-vehicles which is made and operates in a manner different with respect to the indicators described in the above mentioned references.
- This indicator is obtained with the features substantially described with particular reference to the accompanying patent claims.
- The invention will be better understood from the following description, given solely by way of a not-limiting example thereof and with reference to the accompanying drawings, wherein:
- Figs. 1,2 and 3 show the electric control circuit diagram of the present indicator, on three different embodiments, thereof;
- Figs. 4,5 and 6 show further embodiments of the present indicator;
- Fig. 7 shows an exploded perspective view of the indicator according to the invention and the relevant support thereof; -Fig. 8 shows the support of Fig. 7 fitted inside a motor-vehicle and separated with respect to the indicator referred to.
- With reference to the Figs. 1-3, is represented the electric control circuit diagram of three different embodiments of a
parking time indicator 10 for motor-vehicles obtained in accordance with the present invention. - By examining the Fig. 1, it is noted that such an indicator comprises substantially at least a
programmable microprocessor 11 interconnected to adisplay 12 of conventional type (i.e. with LED diodes, luminous, electro-mechanical, electro-luminescent, with liquid cristals, with eventual drivers etc...), as well as comprises apulse shaping circuit 13 built-in with a noise suppressor or limiter filter (not shown) and connected to themicroprocessor 11, aquartz oscillator 14 interconnected to themicroprocessor 11, and a frequency-divider 15, these components being providing a conventional clock, a set ofcontrols 16 for adjustment of the starting and end parking time, and therefore of the duration of the same parking time, and for the clock regulation, in case of need, and finally it comprises anelectric supply 17 which may be constituted either by an autonomous battery built-in in the indicator or by the same motor-vehicles battery, in which case such a supply is constituted by the electric cables (not shown) connected to said motor-vehicle battery, through a suppressor and an eventual voltage stabilizer indicated by thereference numeral 18. - Besides, the indicator may comprise also an auxiliary electric supply as i.e. a buffer battery (not shown), which is cut in automatically in case of mains supply lack or cutoff, in order to keep all the electric circuit components of the same indicator always under voltage and therefore to ensure a continuous operation thereof, before to reset such mains supply.
- In particular, the
display 12 is provided on the considered indicator at a location visible from the outside of the car, and is adapted to indicate the parking starting and end time of the car with numerical digits which are displayed on corresponding positions of the display. - Advantageously, the present indicator may also comprise an
additional display 19 of conventional type, connected to themicroprocessor 11 and arranged within the car at a position visible by the car's driver, for signalling to him both the starting and end time of each parking and the time during the day. - Such an
additional display 19 signals permanently the daily time and in case also the days and the months of each year and is activated by themicroprocessor 11 in the manner hereinafter described, for signalling the starting and end parking time of the car too, which signalling is displayed also on theremaining display 12. - In turn, the
pulse shaping circuit 13 is connected to at least amechanical vibrations sensor 20 of per se known type, fitted inside the car and sensitive to the vibrations produced by the engine and transmitted to the entire motor-vehicle. - Such sensor, in particular, is so realized as to generate an electric pulse only when the vibrations determined by the motor-vehicle engine movement have gone out as soon as such engine is stopped, and to transmit such pulse to the
pulse shaping circuit 13, which thus is activated by generating in turn the electric pulses for the operation of the parking time indicator. - The present indicator operates as follows: on the condition in which the motor-vehicle is still and the engine is stopped, and in which the
microprocessor 11 has been set in advance through thecontrols 16 so as to regulate exactly the solar time and in case the calendar days and months, as well as to count a parking time of pre-established duration corresponding to the duration foreseen by the laws in force, thevibrations sensor 20 doesn't detect the presence of mechanical vibrations of the car and therefore does not generate any electric pulse, so as thepulse shaping circuit 13 remains inactive and doesn't provide for regulating automatically through themicroprocessor 11 the parking starting time and hence the parking end time too. - Under this condition, then, the
microprocessor 11 provides for the operation of the indicator referred to in a conventional manner exclusively as a clock, through theoscillator 14 and the frequency-divider 15, by displaying on theinner display 19 such solar time and in case also the calendar days and months, while on the contrary the starting and end parking time isn't displayed neither on theouter display 12 nor on the specific positions of theinner display 19. - This operative state of the present parking time indicator is kept unchanged even when the car engine is started and such car is driven on movement.
- On the contrary, when the car engine is shutdown and thence the car is stopped on the parking with regulated parking time, the
vibrations sensor 20 detects the disappearance of the engine vibrations which are transmitted to the motor-vehicle, thus generating a correspondent electric pulse which activates thepulse shaping circuit 13, which in turn generates a set of electric pulses whose electric-noises are adequately suppressed through the filter associated with suchpulse shaping circuit 13, wherein these pulses are transmitted to themicroprocessor 11 which identifies them and in response displays the starting and end parking time both on theouter display 12 and the corresponding positions of theinner display 19. Under this condition, then, themicroprocessor 11 is regulated for providing the operation of the present indicator both as a clock, with the same previously described principles, and as a parking time indicator, by displaying the starting and end parking time on theouter display 12 and the specific positions of theinner display 19 and such microprocessor provides for displaying continuously on the two above mentioned displays the time being spent during the car parking and, as soon as the preestablished parking time period is elapsed, said microprocessor stops automatically the count and erases all the parking time numerical indications from both thedisplays - Afterwards, these operative conditions are kept unchanged, as previously described, even when the motor-vehicle engine is started again and the motor-vehicle is driven on movement.
- The
microprocessor 11 of the indicator referred to is activated for operating under the same just described principles, even by utilizing sensors of a type different than that described, in combination with thepulse shaping circuit 13 and themicroprocessor 11, i.e. by utilizing a weight sensor associated with the car's driver seat, which sensor activates said microprocessor when it detects the absence of the driver after that the motor-vehicle has been parked and the engine shutdown, or by utilizing a sensor monitoring the motor-vehicle engine rotation, which activates said microprocessor as soon as such engine has been shutdown after the motor-vehicle has been parked, or also by utilizing sensors of other per se known kinds, which are sensitive to further operative parameters of the motor-vehicle. - Now, by examining the Fig. 2 in which a different embodiment of the present indicator is shown, it is noted that in this case the indicator is constituted by the same previously described circuit components, which therefore are marked with the same numeral references, and that the
oscillator 14 and the frequency-divider 15 are incorporated in the integrated circuit providing for themicroprocessor 11, and thus are no more separated from such microprocessor as formerly. - On the other hand, also this embodiment of the indicator is identical and operates on the same manner of the preceding one.
- Besides, in the Fig. 3 is shown a remote-controlled embodiment of the present indicator, in which it is noted that the indicator is substantially constituted by two
separated units microprocessor 11, thepulse shaping circuit 13, theoscillator 14, the frequency-divider 15 and at least a display, of which theunit 21 acts as a remote-control unit remotely controllable by the user and formed by a least a conventional radio-frequency, supersonic or infrared operatedtransmitter 23, which is interfaced with themicroprocessor 11 and provided with selection push-buttons (not shown), actuatable by the user for the remote regulation of both the calendar time and the parking time, so as to generate and transmit corresponding radio-frequency, supersonic or infrared coded signals, and theunit 22 acts as a receiver unit formed by at least a conventional radio-frequency, supersonic or infrared operatedreceiver 24, syntonized with thetransmitter 23 and interfaced with itsown microprocessor 11, so as to receive the coded signals transmitted by said transmitter and to display the correspondent times selected on the associated display of the receiver unit referred to. - As previously, also in this case the present indicator is activated and de-activated by specific sensors of the above specified type, incorporated in the motor-vehicle and sensitive to different operative parameters of the same motor-vehicle.
- Referring now to the Figs. 4, 5 and 6, three further possible embodiments of the present indicator are shown.
- In Fig. 4, in particular, is noted that the
numerical digits 25 of the time indication are carried by acontinuous wound band 26 of paper or other suitable material, wound onto a set ofapposite rolls 27, which are continuously driven in rotation during the time by amechanic driving unit 28 of conventional type coupled to and controlled by the microprocessor and the other circuit components of the indicator, schematically represented by theunit 29, and such numerical digits are displayed at acorrespondent firm opening 30 provided on the indicator referred to, with the eventual lighting thereof by alamp 31 or the like associated to such numerical digits. - Also in this case, therefore, the indicator is activated and de-activated by suitable sensors built-in on the motor-vehicle, of the described type, in the same specified manners. Furthermore, in Fig. 5 is noted that in this case the
numerical digits 25 of the time indication are carried along the peripheral zone of adisc 32 of transparent material. which is driven in rotation in the course of the time by thedriving unit 28 associated to the same previously citedunit 29, under the control of sensors built-in on the motor-vehicle, and such numerical digits are also displayed at a correspondent firm opening 30 of the indicator, with the eventual lighting thereof by alamp 31 or the like associated to such numerical digits. - Finally, in Fig. 6 is noted that in this case the
numerical digits 25 of the time indication are carried by a plurality ofsectors 33 in which aplate 34 of transparent material is divided, which is associated to the above mentionedunit 29 and the considered sectors are respectively lighted up, in the course of the time, by aluminous beam 35 produced by a lamp or the like incorporated in theunit 29 and deviated by the associated components of such unit toward each sector to be displayed, under the control of the above mentioned sensors built-in on the motor-vehicle. - By examining now the Fig. 7, a
support 36 shaped as a box-like casing for supporting the indicator in accordance with the invention is shown. - This support, in particular, is subdivided in different zones, in the present example a
central zone 37 for supporting and housing thepresent indicator 10 in the manner hereinafter described, and twoside zones - To this scope, the
indicator 10 may be made as aflat box 40 of reduced thickness, in which all the operative components of the indicator, thecontrols 16 and one or more displays are housed, said box being provided with projectedtongues 41 which may be snap coupled intocorresponding recesses 42 provided through thesupport 36, so as to obtain a simple and quick coupling between the two parts, and the numerical digits displaying both the calendar and the parking time are visible through acorrespondent opening 43 provided on the same support. - In turn, the supply voltage of the indicator operative components is obtained by a battery (not shown), which may be housed within the
box 40 or outside thereof, and in this latter case such battery may be housed on thesupport 36 too, and is electrically connected to said operative components by metallic parts associated with thetongues 41 and therecesses 42. - Likewise, the supply voltage may be provided also by the same motor-vehicle battery, which is connected through an electic cable (not shown) to said operative components of the
indicator 10. - Finally, by examining the Fig. 8, is shown the
indicator 10 separated from thesupport 36, which in turn is fitted from the interior compartment of a motor-vehicle 44 against thefront glass 45 thereof, so as the parking time displayed on theouter display 12 of such indicator is visible from the outside. - The so obtained parking time indicator, therefore, permits to regulate in a simple and quick manner the relevant parking times, the course of which occurs automatically and such indicator can be always found too for performing its function, as it is incorporated on the
support 36 which is fitted at a visible position on the motor-vehicle, which support also provides for supporting other documents useful for the motorist, as in the case of the above mentioned insurance badge and licence tag. - Moreover, this indicator is versatile also for performing eventual additional control and inspection functions of the motor-vehicle operative state, by incorporating to this aim the relevant-circuits thereof on the integrated circuits of the microprocessor of the same indicator.
- In this way, it is possible to incorporate on the indicator, by way of example, thermometers, antitheft devices, pressure switches, pressure gauges, measuring instruments for electric quantities of different kind, signalling devices, antennas, altimeters and similar components, which usually are built-in separately on the motor-vehicle, thus obtaining these single devices to be eliminated and the incorporation thereof on the single integrated circuit contained on the microprocessor, with consequent considerable costs reductions and productive simplification and rationalization.
