For this purpose there is provided a communication device electrically coupled with the emergency light circuit, switching circuit which is in operating position in the position of the gear shift lever locked in the reverse or reverse gear position, and through which the flashing lights come on simultaneously and at intervals without turning the operating switch on

Description

ELECTRICAL CIRCUIT OF EMERGENCY LIGHTS FOR AUTOMOTIVE VEHICLES Field and Background of the Invention The invention relates to an electric circuit of emergency lights for motor vehicles, with a hand-operated switch in the circuit. The circuit has at least four intermittent flashing lights which can be individually turned on manually, and has switching transistors associated with the lights. In the ON position of the switch, the flashing lights are activated simultaneously and flash at intervals. Motor vehicles are conventionally equipped with emergency lighting circuits of the type mentioned above, which in hazardous situations, such as the breakdown of the vehicle, the puncture of a tire (or rim in Mexico), found in the tail ("al end) of a traffic jam, and similar situations, are ignited by the actuation of a manually operable switch, so that the flashing lights provided in the automotive vehicle flash simultaneously at intervals, and are usually specifically lights of yellow / orange color.

In the case of trucks. additionally provide marginal lights in upper and outer locations around the rear hatch (rear) of the vehicle, which have the function of intermittent flashing lights. The tailgate (ramp type) can be opened and lowered out, and most of the time takes the form of a hydraulic ramp. The marginal or position lights are integrated into the electric circuit circuit of emergency lights and clearly mark for other drivers the extended space occupied by the vehicle when lowering (or opening) the hydraulic ramp / tailgate. The simultaneous intermittent flashing at intervals of the emergency lights of a motor vehicle has the advantage that the other participants in the traffic (the other drivers) can be aware of the intermittent light effect even when the corresponding motor vehicle can not be see directly Description of the Invention The present invention is based on the utility of this emergency light effect to (use it in) automotive vehicles that move in reverse. Accident statistics reveal that, particularly in city traffic, during the march backwards (in reverse) when leaving, for example, garage doors, parking spaces or parking, and the like, relatively often accidents occur because motor vehicles that drive in reverse (going backwards) often can not be seen directly (by drivers) in the flow of traffic in motion. The signaling effect of the rear white lights for reversing of existing automotive vehicles (currently) is not satisfactory, especially when reversing to exit a garage. Therefore, the invention deals with the problem of providing an electric circuit of emergency lights for motor vehicles in accordance with the type described above by which, every time with the ignition on the transmission is put in reverse (for reversing) with the gearshift lever, emergency lights that emit flashes are also activated. According to the invention, the problem is solved by providing a switching device coupled to the emergency light circuit, which device is in operating position with the position of the gear shift lever of the motor vehicle locked in the reverse or Reverse the transmission, and with the ignition of the vehicle in the on position, and simultaneously turn on the intermittent flashing lights of the circuit so that they flash at intervals. Preferably, the switching device is additionally coupled with the circuit for the (white) reversing lights of the motor vehicle. The switching device can be executed to be electromechanical or electronic. The various features of novelty that characterize the invention are highlighted with particularity in the appended claims forming part of this disclosure. For a better understanding of the invention, its advantages in operation and specific objects that are achieved through its use, reference is made to the appended drawings and the descriptive part in which a preferred embodiment of the invention is illustrated. BRIEF DESCRIPTION OF THE DRAWINGS The only figure of the drawing is a schematic diagram of the circuit according to the invention. DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention will now be explained in detail in conjunction with the single figure of the drawing which schematically illustrates an electric circuit of emergency lights.

In a circuit 3 connected in series with a battery or accumulator 9 of a motor vehicle, an electrical switching transistor or relay 10 and the flashing lights 4 of the usual emergency light circuit 1, a hand-operated switch 2 is provided . If the switch 2 is turned on (closes), simultaneous ignition is caused at intervals of at least four flashing lights 4 of the motor vehicle, which are connected in parallel and are subsequent to the switching transistor 10 in the circuit 3 , in the way that this usually happens in the case of a dangerous situation, in order to warn other users of the road, street or road. According to the invention, with each interlock of a gear change lever 6 of a motor vehicle in the reverse or reversing position 7 (R) of the gears of the transmission 8 of the motor vehicle, and with the switch I of Ignition ignited by means of ignition means 12, the closing of the circuit is carried out by another switch or dispsitive 5 switch integrated in a second circuit 11 to automatically turn on transistor 10 and flashing lights 4 of circuit 1 of lights of emergency. The transmission 8 also has gears for forward or forward travel, such as the first to fifth speeds. The circuit 11 contains the means 5 for changing gears, the battery or accumulator 9, the transistor 10 and the lights 4, connected in series. According to the invention, with each change of speed to engage (insert) the reverse 7, and each reverse movement of this resulting from the automotive vehicle, the attention of other users of the street or road to the motor vehicle is called it is reversing with emergency flashing lights, even if the vehicle itself, when moving out of a garage door or a parking space, can not be seen by other street users or path. By means of the relatively simple additional switching measures that can be adapted afterwards without incurring large expenses in other motor vehicles, if they are provided with a conventional electric emergency light circuit, greater safety in traffic is guaranteed. a specific embodiment of the invention has been shown and described in detail to illustrate the application of the principles of the invention, it is understood that it is possible to carry out the invention in other ways without departing from these principles.
