DESCRIPTION

TURN SIGNAL ARRANGEMENT FOR VEHICLES

Object of the invention.

The present invention refers to a turn signal arrangement for vehicles, allowing to warn the exterior of the intention to turn or manoeuver to the exterior effectively from within all of its surroundings.

Background of the invention.

At present, vehicles in transit on public highways are endowed with manoeuver signal means, so that other pedestrians or vehicles can know in advance the change in trajectory that said vehicle is going to undertake.

Thus, vehicles such as automobiles, buses, trucks and bicycles amongst others, comprise turn signal lights, sidelights, brake lights and others.

A specially important case is the use of a turn signal lights, those which comprise a first set of independent signal lights on one side of the vehicle connected to a first operating circuit, of a central unit, and a second set of independent signal lights on the other side of the vehicle, connected to a second operating circuit of the previously cited central unit. Both sets of signal lights comprise at least a frontal signal light and a rear signal light. Thus, if a public highway user observes the vehicle from the rear area or from the frontal area, can warn of the signal, activated by the driver when the corresponding light ignites on one side or the other of the vehicle, mainly with a striking intermittance that the central unit provokes.

However, there is the problem that if the vehicle is observed sideways, it is posible that none of said lights can be seen, so therefore cannot warn of the manoeuver signal.

To this end manufacturers place an additional signal light on a side part of the vehicle, for example on the front wing of an automobile or on the corresponding mirror, connected to the circuit of the pair of signal lights on the same side, which represents a notorious advantage. Now it is possible to know if the vehicle is going to turn so as to approach the observer of the previous situation at an angle of approximately 180 Q . However, if the activated signal lights are those on the opposite side to the observed side of the vehicle, said situation remains unnoticed 5 with the risk that this entails in transit. This problem is aggravated in the case that the vehicle is equipped with a

"warning" or warning command, with which all the signal lights will be activated intermittantly. If for some reason, only the signal lights on one side can be observed, said warning situation cannot be correctly noticed and the message received by the user of the public highway is that the vehicle is going to turn, which represents a risk of clear and notorious error.

Description of the invention.

A turn signal arrangement for vehicles, object of this invention, has some technical particularities destined to allow a better external signal of a turn manoeuvers and the warning signal from any point of external view of the vehicle.

According to the invention, applicable to any vehicle in transit on street and road, such as automobiles, trucks, buses, motorcycles, bicycles and others, comprise a set of signal lights on each side of the vehicle, arranged substantially vertically aligned, a first signal light of both pairs being connected to the first operating circuit of the signal lights and a second signal light of both pairs with the second operating circuit of the signal lights, so that observing the vehicle from one side, the pair of signal lights is visible, and indicates a turn maneuver of the vehicle by turning on of one or another of the two signal lights, or the warning signal by turning on of both signal lights of the pairs. Thus, accomplishing that a turn indication or signal be easily noticeable from any point around the vehicle, both from the front and the back by means of the sets of conventional lights, as well as from the sides of the vehicle by means of the pairs of indicator lights, said indications being visible even if they correspond to a maneuver towards the opposite side at which the observer is. This allows an increase in road safety and better appreciation of a turn or warning signal that is carried out by each vehicle. In a preferred embodiment, of the pair of signal lights of a side of the vehicle, the signal light in upper arrangement is connected to the circuit of signal lights of the opposite side of the vehicle and the signal light in lower arrangement is connected to the circuit of signal lights of the same side. Thus whichever side of a vehicle from one side is observed by a user of the public highway, if he visualizes the upper signal light of the side of the vehicle, he will know that the vehicle will turn in the direction opposite to him, and if he visualizes the lower signal light of the side of the vehicle, he will know that the vehicle will turn in the direction towards him. The possibility that the indication is reversed is not ruled out. Also that the upper signal light of the pair means that the vehicle is going to turn to his left and that the lower signal light of the pair means that the vehicle is going to turn to his right, or vice versa.

The two signal lights of an indicator side pair are spaced apart by a suitable distance in order to be distinguishable from a distance. Thus, even if the observer is notably separated from the vehicle, he can still distinguish with clarity which signal light of the pair is the one that is turned on.

Furthermore, in an embodiment, the invention comprises some differential operating means of one of the signal lights of the pair associated to the operating circuit of the signal lights of the opposite side. Thus, for example, with the intermittent turning on of the corresponding signal light, the other signal light of the pair can be permanently turned on with more or less intensity, appropriate for its use at night.

The pairs of signal lights on the sides of the vehicle are arranged at an elevated point of the vehicle bodywork, preferably, in a place as far forward as possible, or on the roof with a planar configuration. In this way achieving better visibility and even the appreciation from an upper view.

This arrangement of signal lights is easily installable at manufacturers for new vehicles or make kits or modification sets to update already manufactured vehicles, such as automobiles, adapting them to the new signal, more safe and reliable.

Description of the figures. To supplement the description being made and with the object of facilitating the comprehension of the characteristics of the invention, a set of drawings is attached to the present specification in which, with illustrative and non limitative character, the following has been depicted: - Figure 1 shows a view from one side of a vehicle with the 5 signal light arrangement of the invention.

- Figure 2 shows a distribution schema of the signal lights connected to the operating circuits of the electronic central unit.

Preferred embodiment of the invention.

As can be observed in the referenced figures, a turn maneuver signal light arrangement in a automobile vehicle comprises a first set of signal lights (1 a) on a side, connected to a first operating circuit (2a) of an electronic (2) central unit and a second set of signal lights (1 b) on the other side, connected to a second operating circuit (2b) of the same central unit (2), which has the corresponding activation (21 ) controls independent from each of the operating circuits (2a, 2b) for a turn signal, and a simultaneous activation control (22) for the "warning" signal or emergency.

The vehicle (V) has on each side, a pair of signal lights (3a, 3b) arranged vertically aligned, so that they are clearly visible when an external observer sees the vehicle (V) sideways or from one side.

Each pair of signal lights (3a, 3b) comprise a first signal light (3a) connected to the first operating circuit (2a) of the central unit (2) and a second signal light (3b) connected to the second operating circuit of (2b) the central unit (2).

In the example of Figure 1 , the first signal light (3a) of the pair is arranged in the upper part and is connected to the first operating circuit (2a) corresponding to the hidden side of the vehicle. In turn, the second signal light (3b) of the pair is arranged on the lower part and is connected to the second operating circuit (2b), corresponding to the side seen together with the signal lights (1 b) of the second pair that can be seen. Therefore, when one of the signal lights is observed (3a, 3b) to be turned on, the observer located to one side of the vehicle will know if said vehicle is going to turn towards one side or another, and if he observes both signal lights turned on (3a, 3b) he will know that the vehicle is not going to turn, but rather that the "warning" or warning device is activated.

Once the nature of the invention has been sufficiently described, as well as an example of a preferred embodiment, it is made known for the pertinent purposes that the materials, shape, size and arrangement of the described elements may be modified, provided it does not entail an alteration of the essential characteristics of the invention that are claimed as follows.
