The present invention relates to a control device a *! distance for the operation of organs, devices and devices! lj accessories, mechanical, electrical and electro-mechanical ins-j talléa on motor vehicles-5 The object of the invention is particularly, but not exclusively, to facilitate such an operation for drivers, provided with the F permit, that is that is to say to drivers who do not enjoy their full physical faculties or who, quite simply, do not have both their hands.

The problem of allowing the driving of motor vehicles for the disabled has been satisfactorily resolved by means of devices and apparatuses which modify the essential controls of the vehicle such as the steering, the clutch,. the accelerator and the brake, but the problem of maneuvering the accessory, mechanical, electrical and electro-mechanical components, apparatus and devices installed on these very vehicles is still unresolved to this day.

I For example, the problem of being able to maneuver the steering and therefore to let someone drive the vehicle

A mofcoA · j · alone,. . „.

added ^ U1 does not have a / hand has been solved in a satisfactory manner by equipping the vehicle's steering wheel with a knob, or ball, essentially spherical integral with it j and allowing precisely rotate the steering wheel in use; health with one hand while the problem still remains unresolved the problem is to ensure that the same person has full control of the vehicle | ! | course consisting in the handling of the above-mentioned accessory organs | mentioned such as, for example, the starter motor, the windscreen wipers, the horn, the lights and the direction indicators! ! tion.

, 3Q The realization of a single command within reach of the sole hand of the user, who obviously can not let go of the po-j meau, has significant and numerous drawbacks due to the rotational movements that the steering wheel performs with respect to the steering column and the dashboard. j3 $. Such movements in fact make any realization impossible! j: station tending to install the steering controls on the steering wheel; * work - like buttons or levers - of the accessory organs! I; in question and then link them to each other at | | : means of electric wires.

} 4Q i We have proposed a solution using conductive wires, ‘J 7- - - ----- ') 1' 'with a connection that is partly fixed and partly mobile, produced also; i by means of movable conductive rings and fixed contacts sliding thereon. *

This solution also proved to be very complicated and unsatisfactory owing to the space and cost problems which it presented.

. As a result, the problem of giving disabled people with one hand · complete control of a vehicle has remained unresolved to date. The object of the present invention is therefore to provide a device which offers a completely new and satisfactory solution to such a problem. j ίi It allows to have on the steering wheel and, therefore, to: within reach of the driver who actuates the steering wheel, all the controls of the accessory organs in question; by solving the problem of the transmission of control movements to each accessory member by means of the use of a mobile transmitting station on the steering wheel and a fixed receiving station provided behind the steering wheel or on the steering column of the dashboard, the transmission of signals occurring by the passage of coded signals from the transmitter to the receiver over a | bearing. .

§ In a preferred form of the invention, transmission! "From transmitter to receiver is done using ultra-}!" 23 sounds. ; | The device according to the invention uses a system compre-j j nsnt a channel transmitter attached to the steering wheel, and therefore mobile, with · | l an autonomous battery supply and a fixed receiver; ! . j installed behind the steering wheel, on the steering column, and | 3C j powered by the automobile battery. 1 1 The transmitter is essentially composed of an oscillator i il ',,,! • quartz and an integrated circuit to which several j <buttons are connected, one for each command to be performed remotely. The operation of all the buttons causes an integrated frequency oscillation at the output of the circuit I '33, b each adjacent button.

j: The oscillation generated by it integrated circuit, amplified j in an appropriate manner, feeds a special transducer constituted I by an ultrasonic transmission signal.

S j The receiver in turn re. ^ Nt the ultrasounds emitted by i îi I ", î ï! • the transmitter, via an ultrasound receiving capsule. j

The received signal is amplified by operational amplifier means and it is applied to an integrated circuit also provided with a quartz oscillator. In the receiver, there is, therefore, a frequency beat between the frequency received by the capsule and that which is generated by the quartz oscillator; 1b difference between the two frequencies causes, in the receiver, on the various outputs of the integrated circuit, a variation in voltage sufficient to bias a current amplifier transistor for the excitation of a corresponding switch or switch element . t

As a final result, we obtain, by pressing a given button on the transmitter assembly, the excitation of an in- (Ί5 switch or corresponding switch).

Naturally, the switching elements or switches of the receiver will be of the bistable or step-by-step type, for the activation of specific organs, or else of the normal or monostatic type for the actuation of the other organs.

2C Will obviously be of the bistable type those for the contact control (starting of the electric circuit) of the lights (of position, crossing and road), of the wipers, of the internal air conditioning and of the heating and the like, tensioned · I that will be of the monostable type for example those for the setting in j 2 ^ action of the starter, calls of headlights, the horn so- | nore.

The maximum number of organs that can be operated at dis! tance by means of the device according to the invention is twenty. four but of course we can provide the possibility of ordering 30 of them at a lower number, depending on the type of vehicle. driver and demands of the driver.

; The invention will be described in more detail with reference to the accompanying drawings cî-ib which is shown a form of exec.u- "i tion lice * ia remote control of eleven different organs.

I The operation of each of these buttons causes the> 1 I movement of the associated organ to be put into effect by means of the action of a stable or bistable mono-1 * j relay.

It 30d; I) e such relays are all contained in the receiver assembly 13 (Fig. 2 and 3) which comprises an ültrt | l * sounds receiver capsule 16, at least one operational amplifier 18, one assembly | 1 crystal oscillator 19 - integrated circuit 20 with eleven outputs, I | and eleven operating groups, indicated by the references 21 to "35 29A, comprising 1st. references 24A and 29, which are connected pectively to the outputs of the quartz oscillator 20, and they are made up; each, as illustrated in fig.4, for 1 "I grouju 22" for a current amplifier transistor 22B and we 1 r "1 a i 22'0.

"27, 29 and 29A will be of the step-by-step or bistable type, while: * the others will be of the normal, monostable, timed type.

The operation of the device will now be illustrated with reference, by way of example, to the starting of the vehicle engine.

In the device shown on the drawings, to put. when the engine is running, the driver must press button 2 (Fig.1 and 3), after switching on the button 1. ·

The operation of the button 2 causes, at the output of the set-10 Lie crystal oscillator 11 - integrated circuit 12, the appearance of a signal of predetermined frequency obtained by the combination of the proper oscillation frequency of the J quartz oscillator 11 and the "modulating" generated by the integrated circuit 12 by the setting of button 2. j 13 Such a signal of predetermined frequency is applied to the transmission capsule 13 which transmits it to the receiver 15 *. !

In the receiver 15, the signal is picked up by the receiving capsule 16, amplified by the operational amplifier 18 and! applied to the crystal oscillator assembly 19 - integrated circuit; 20 20 where there is a frequency beat between the frequency of the Bignal picked up by the capsule 16 and the fixed frequency of the quartz oscillator 19 · The difference in value between these two frequencies causes, on the output of the oscillator assembly 19! - integrated circuit 20, to which the group 22 is connected, a signal j 21 of sufficient voltage to bias the bese of the current amplifier transistor 22B (FIG. 4) which causes the excitation,

3C ’Obviously, given the monostable nature of the 22G relay, starter operation will stop as soon as the driver releases button 2.

! Obviously, we will have a succession of similar functions. 'for any other button pushed, with the only difference that the operation of any organ associated with a bistable relay will persist after ie r <iaii'n-ui tit iu corresponding button and, pouj stop this ionotionn «. and, ii: * ΤΘ necessary to press the j * button. 1 .u.
