Automatic light signaling device for safety purposes on motor vehicles

The invention relates to an electric, automatic Safety device which uses light signals to indicate that the vehicle is at a standstill when the vehicle is switched off or with the engine running slowly and with poor visibility, which in this way causes the well-known and sometimes serious accidents that result these facts are. ■.

The device can be applied to a any force [vehicle to be mounted either on a motor car, a j 'truck or another vehicle type, and this is fed from the vehicle I of the battery.

The device is automatically operated by that valve controlled, which is suitable and intended for displaying the pressure of the lubricating oil in the engine. This valve is on the Vehicles of this type are always present and usually have the task of lighting up a warning light in this way the insufficient oil pressure in the lubrication circuit

to show.

This control lamp lights up whenever the engine is switched off while the ignition circuit is still closed is.

According to a particular embodiment of the invention, the device according to the invention controls which of the aforementioned The valve is actuated by emergency signaling devices, which normally consist of ordinary lamps that carry the Form the usual equipment of the motor vehicles. These are, for example, the front position lights that side and rear indicators and the StogpHchter. this follows a predetermined flashing rhythm with which the vehicles concerned are warned of an obstacle, and even in the dark or in fog, this obstacle in this case from an emergency vehicle consists.

According to a further feature of the invention it is provided to design the device in such a way that safety signals even when the engine is running and the vehicle is at a standstill or may also be handed in while the vehicle is in motion. This is particularly evident in fog or in Convoy travel extremely beneficial and useful.

To this end, the device, which in principle is based on the commutation of two three-pole electromagnetic Interrupters are based, the supply of which from a small piston inserted into the lubricant circuit of the engine occurs, when the vehicle is at a standstill and the engine is switched off, intermittent light signals are switched on in the aforementioned lights * to steer. The device is provided with a further interrupter, which is used as an "emergency signal" or "emergency control" and which, when the engine is switched on and the vehicle is stopped, the interrupter generator with the above-mentioned luminous bodies » electrically connects.

However, when the engine is started, a commutation system, which is controlled by the rotation of the odometer, ensures that when the breaker is always on, the breaker generator is only connected to the front position lights and the stop lights
To distinguish signal when the vehicle is stopped from that when the vehicle is moving.

In addition, a me- ' mechanical interrupter is provided, which switches on! the stop light excludes if the brake pedal and an elec- * tromagnetic, three-pole breaker are depressed, which excludes the switching on of the front position lights, which remain on when the direction of travel; indicator is switched on.

The same electromagnetic breaker causes
that when the vehicle is at a standstill, the engine is switched on and the direction indicators are switched on, the safety light signaling devices are only in operation with regard to the stair lights i

The device according to the invention is in the form of an exemplary embodiment illustrated in more detail on the basis of the drawing. In this, show in a purely schematic way:

In the embodiment of the invention according to FIGS. 1 j

and 2 makes it the general breaker I ₄ . possible either

'i

to switch on the ignition of the motor via the interrupter I ₂ and the contacts i ^ and i ^ or the supply of the \ interrupter generator G-. via the contacts i ^ .. and i ^ zu;

supply.

The contact pair i ^ c and l * r is closed at the same time when the contacts i ^ and i-ip »-H 3 ^{un (} * ^ 14 of ^the interrupter I ^ are opened, to the front position lights L ,, and L ₂ with the voltage of a Battery, these lamps L

and Lp are not fed by the contacts irg and ic ₀ »which have remained open after the general breaker I ^ has been opened, while the emergency breaker Ιλ is not open, which is the case, for example, when the motor is switched on via the Emergency stop — he's shut down.

The diode D, - interrupts the ignition of the front lamps via the breaker generator.

The outputs 1 and 2 of the generator G ^ supply all of the aforementioned, illuminated parts and elements when - when the engine is abge - the interrupter I ,, which consists of a piston inserted into the oil circuit of the engine, is closed and via the contacts I ^ and i ^ ₂ enables the battery to be supplied via the main relays Re ^ and Re ₂ , which are energized.

_{The output 1 of the generator G ^ supplies the front position lights L ^ and L 2} via the contacts r, j, and r ^ and via the contacts i ^ g and i ™, and the lamp L via the contacts r ^ and r ^ 2v ~, and via the contacts r ,, Q and τ * η the lamp

The output 2 of the generator G ^ supplies via the contacts T ₂ -] and r ₂ , and i ^ ₂ or i ^ the two lamps L, - and Lg via the contacts γ _? λ and r ₂ g the lamp 8 and via the contacts ν2η and r ₂ g the lamp L ^.

When the engine is ignited, the interrupter I ₇ opens the contacts 1-, _Λ and i, _o and therefore the relays Re _{1 and Re 2} return to their rest position, with the interruption

30982Λ / 07Λ3

all lights are turned off.

To restore fills the vehicle still stops, it is sufficient to switch on the mechanical breaker I ^, which "solder contact" or "emergency drive" is called.

In this case, the contacts i> ₇ and i- ₈ of part I, via the contacts r ^ _Q and r- ^ y of the relay Re- in the rest position. To close the supply circuit from the battery to the relays Re ^ and Re ^, which are energized and cause the group of eight lights or lamps to be lower, via the contacts r, - * and r _{c - of the relay Rec.}

The diode D ^ prevents that during operation of the relays Re ₁ and Re _? When the vehicle is stationary and the engine is ignited, the oil pressure indicator, which is conventionally arranged in vehicles, is actually live.

The capacitor Cg and the diode D ,, which are switched on by the contact 1 ^ ₁ - of the interrupter I., allow a greater switch-on reliability of the relays Re ^ and Re, in the event of too fast operation when the interrupter I is switched on . The control lamp L ^ ₀ , which is connected to the contacts r-, Λ, r ^ / - of the relay Re- *, shows the Fahrzeuj2jahrer that the device is properly switched on while driving. The contacts. i, - »and i, -, - of the interrupter I. ruien the emptying of the capacitor Cg when the interrupter L · is switched off.

If the engine is in operation when the vehicle is stationary, the control of the direction indicators is activated. This is done via the flashing light switch Ig shown in FIG. 1; for example, the left flashing light is switched on by closing the contacts ir ^ and igp, while the relay Re ₁ - is fed from the battery via the diode D ^ with a pulsating current from the interrupter generator G ₂

will; the relay Re ₁ - is energized and opens the Kent clocks r _r ^ and tv ,, whereby the supply circuit of the relays Re * and Re _{2 is} interrupted, which in turn return to the rest position. Via the contacts V ^ and T ₅₈ , the generator Ci. starting from the lamp Lq, which the power of the generator G., compensates.

Dor Generator Gp supplies the lamp Ly via the contacts v * , - and r., R and the lamp L., Via the contacts r ^ c and r ^ A.

In parallel with the relay Re ₁ - the capacitor C ₁ - large capacitance is arranged. He will be with. applied to the pulsating current and supplies a direct voltage to the excitation coil of the relay Re.

The second diode Dp prevents the intermittent Power is also supplied to the lamps Li and L- at the same time.

The same also applies to the lamps L _L and L ^ - when the contacts ig., And .L-- close to indicate an i / ahrt to the right.

Simultaneously with the operation of the lamps L ₇ and L _ß (or L, and LJ indicating the direction of travel), the contacts I ₁ * and i- _? Of the interrupter I / and the contacts i _ro and ir-, of the interrupter I ₅ die uc iden rear stop lights L ₁ - and Lr acted upon intermittently.

This operating state, which for c'.afj stiLlotehende vehicle with the engine in operation and for those that are switched on Direction indicator is described, is also when the vehicle is moving and when the direction indicators are switched on, because the entire complex, which is formed by the relays Re- and Re-, switches off all eight lamps while the vehicle is moving, allow the relay Rep-

will / 2

switches that the contacts V ^ and r "opens.

The interruption of the operation of the luminous bodies while the vehicle is in motion takes place in such a way that the "supply _{circuit with the relays Re ^ and Re 2} via the contacts T-zrj and r-, ο the relays Re- * and Re ^ is interrupted, the excitation of which is controlled by a turntable S controlled by an odometer or, if necessary, by some other rotatable member when the vehicle is in motion.

Such a disk contains one or more sections, the number being odd, which consists of an alternating conductive and insulating material, which are nested one inside the other. Opposite contacts s ^ and S ₂ move along these sectors.

In the case in which only a single material is used as the material for the sector, extends the sector covers an area smaller than Is 180 °. .

The pin of the disc is connected to the negative pole of the battery. If necessary, this pivot pin is connected to the ground of the vehicle. 'When the disk is in the rest position (the vehicle is stopped), one of two contacts, for example, the contact touch s ,, an insulated sector, while the other contact S ₂ touches a conductive sector. In this. In this case, the capacitors CU and CN are charged with the voltage of the battery, ... and that via the corresponding parts r ,,, r ,, - and 1 * 47 » ^r 48 * while the capacitor C ^ remains discharged, since one of them its coverings is isolated from the sector s ^.

Once the vehicle is on the move ', the disk S, and the sliding contact s ^ rotates moves across a group consisting of conductive material sector of time, the capacitor C _1, which was .entladen ^, is connected to the battery and charges with the battery power. The charging current of the capacitor CL excites the coils of the re-

lais Re, and Reλ, which are connected in parallel to each other.

The subsequent actuation, i.e. switching on the relays Re- and Re ^, causes the previously charged capacitors CU and C ^ to be switched in parallel to the corresponding windings of the relays Re- and Re ^. This is done by means of the contacts r ^, r ^ g and r < ₇ , Γ / q, which keep the coils connected to voltage while the disc rotates.

It should be noted that the capacitor C, in particular, remains charged by the supply circuit, this circuit starting from the positive pole of the battery and via parts 1 ^ ₅ , i ^ ₆ , r ^, T _{1 + 6} , τ ^ , r ^ leads to the negative pole via the conductive sector of the disk S: the switching off and interruption of the charging current as a result of the rotary movement of the disk S is nevertheless compensated for by the increased capacitance of the capacitor C ^. The same considerations apply mutatis mutandis to the capacitor C ^.

The resistors R. and Rp have the task of the capacitors (L · and Cp when the vehicle is stationary and when the Discharge engine.

The capacitors C, and C / are with the negative coating at least connected to the battery, while the positive pad is connected to the contact i ^ of the interrupter I ^ are connected for the purpose of driving the vehicle stay charged and the relays Re ^ and Re ^ switched on to keep.

The commutation of the relay Re causes, depending on the contacts r ^ y, r ^ _Q, the opening of the supply circuit of the relays Re ^ and Re ₂ and consequently the switching off of the emergency signal devices or the lamps L ^, L _Q , L ^ 'and l ,. The interruption is only maintained with respect to the lamps L ₅ and L ^ by means of the contacts i ^ ,,, i _{/ 2} , i, -p »

ic- and regarding the larapen L ^ and L ^ by means of the output 1 of the generator G ^ and the parts T ^, r, - ^, i ^ -z, i ^ and

When the brake pedal is depressed, the interrupter Ij- is commutated and the contact i "moves from the position lap to the position la * , whereby in this way the interruption of the stop lights is excluded, which light up until the brake pedal is pressed or is kicked. At the same time, the front position lights remain in operation with continuous light, namely after the interrupter I _{n has been closed} .

Another embodiment of the invention Device for switching on the interruption on all lamps in the event of the vehicle being driven, with always the hot signal device Ιλ is turned on, can be realized in the way v / ground that a breaker is provided, which is from the fan of the engine or from the fan of the alternator or the alternator is controlled. The breaker can come from an ampoule filled with mercury and consist of a lamella, which in the rest position closes the supply circuit of the relays Re ^ and Re ~.

While the vehicle is in motion, the rotational speed or peripheral speed of the fan increases; simultaneously but the air pressure generated also rises, which moves the lamella away from the ampoule, which "opens" and "opens" the circuit in this way the supply of the relays Re ^ and Rep interrupts.

It is clear that this slat is calibrated and dimensioned so that when the vehicle is stationary and switched on Motor, the fan, which is operated at low speed, cannot move the lamella out of its rest position.

According to a further feature of the invention, it is provided that when the brake pedal is pressed, in the event of a danger, in addition to the rear stop lights, which is normally the case - ¹ also the rear and side

Chen turn signals and the front position lights are switched on, which are applied with intermittent pulses in order to mainly indicate in this way that the vehicle is in the braking state. This is done in that the normal interrupter, which is controlled by the brake pedal, comes into action on an auxiliary relay, the movable contacts of which on the one hand continuously switch on the rear stop lights and on the other hand the relay Re-. and Re ₂ , which inject intermittent pulses into the aforementioned signal lamps.

It is of course clear that even in the event of braking - provided that the driver of the vehicle pulls the lever of the direction indicator actuated - the emergency device is switched off, while those side indicators of the direction of travel remain switched on, which the vehicle is to take.
