Description

Object of the invention.

The invention relates to a warning device for vehicles with the ignition key in the locked position with the position lights on; and mainly for two or three wheel vehicles.

This device provides a warning signal to the user when he places the vehicle's ignition key in the locked position with the position lights on: avoiding said warning signal that the user unintentionally leaves the vehicle's contact in that position, causing the depletion of The vehicle's power supply battery.

Field of application of the invention.

This invention is applicable in the dedicated field of the manufacture of auxiliary signaling devices for vehicles, and in particular for signaling the status of the position lights, when the ignition key is in a locked position with position lights on.

Background of the invention.

Motor vehicles have a contact key that can be placed by the user in different positions, it is common for motorcycles that said contact key has: an unlocked position for starting the vehicle, a locked position in the which prevents the start of the vehicle and the movement of the steering, and a locked position with position lights on, in which, in addition to the functions of the locked position, performs the automatic ignition of the position lights for better signaling of

vehicle.

It is common for the user to unintentionally leave the motorcycle with the contact in the locked position with position lights on, instead of in the locked position, thus leaving the motorcycle unnecessarily with the position lights on.

When the motorcycle remains parked for some time in these conditions, the position lights cause the vehicle battery to drain and drain, with the consequent inconvenience and repair costs for the user.

The applicant for the invention is unaware of the existence of a background to solve the indicated problem.

Description of the invention

To solve the aforementioned problems, a warning device for vehicles with the ignition key has been devised in a locked position with illuminated position lights, which is of great constructive simplicity, low manufacturing cost and easy installation on the motorcycle or The vehicle in question has particularities oriented to provide a light and / or acoustic signaling when the user places the ignition key in said locked position with position lights on.

This signaling, which can be luminous and / or acoustic, makes the user aware of the action taken and can decide if it has been a voluntary act, or on the contrary, it is an involuntary action.

With the warning signal, emitted by the device, it is intended to prevent the user from involuntarily leaving the ignition key in the locked position with position lights on and, consequently, that said position lights can discharge the battery during the time in which the vehicle is not

using.

To achieve the proposed objectives, the device of the invention comprises a control unit to which a light and / or acoustic signaling element is connected, and inputs for the reception of at least: a first command signal of the position lights, whose ignition you want to signal; and of a second command signal of any other vehicle element or circuit that remains inactive when the ignition key is in the locked position with position lights on and which remains active in any other position of the ignition key; said control unit carrying out the supply or ignition of the signaling element only when the first signal is active and the second signal is inactive.

Since the purpose of the device is to signal the activation of the connection of the position lights when the ignition key is placed in the locked position with the position lights on, the first signal to be used will be the command of said position lights . Since this first signal is used in other positions of the ignition key in which the device must not emit any signaling or warning, a second signal is selected that is inactive when the ignition key is placed in the locked position with lights. position on, but that is active in the other positions of the ignition key.

By way of example, this second signal can be the lighting of the vehicle frame, although any other signal that meets the same condition can be used.

Based on the two signals mentioned above, the different states and the unique position in which the control unit will cause the signaling element to be powered on or on is shown below and said element will emit a signal indicating that the ignition key is in place. in the locked position with position lights on.

Description of the figures.

To complement the description that is being made and in order to facilitate the understanding of the characteristics of the invention, a set of drawings is attached to the present specification in which, for illustrative and non-limiting purposes, the following has been represented:

10 -Figure 1 shows an embodiment of the warning device for vehicles with the contact in the locked position and position lights on, according to the invention, in which the control unit is constituted by relay contacts.

-

Figure 2 shows a variant embodiment of the device of the invention, in

what the control unit consists of an integrated circuit.

-

Figure 3 shows a variant embodiment of the device of the invention, in

20 what the control unit is constituted by a microprocessor implementing a control function.

Preferred Embodiment of the Invention

In the exemplary embodiment shown in Figure 1, the device comprises: a control unit (1 a) consisting of two relays (11, 12) switched or not, provided with individual inputs for the reception of a corresponding first command signal. in this case the position lights (2) of the vehicle whose ignition is to be signaled when the vehicle's ignition key is in a locked position with the position lights on; and of a second control signal of an element (3) or circuit, corresponding in this case to the illumination of the vehicle panel, which remains inactive with the ignition key in the locked position with position lights on and which remains active in any other position of the contact key; said control unit (1 a) feeding or turning on the element

(4) light and / or acoustic signaling only when the first signal is active and the second signal is inactive.

In the variant embodiment shown in Figure 2, the control unit (1 b) is constituted by an integrated circuit with logic functions (13, 14), NOR or ANO, such as integrated circuits 7402 or 4093 for example. .

This system has as its main advantage the simplicity of operation and the small size. As in the previous example, the combination of a first command signal will be used, corresponding in this case to the position lights

(2) whose ignition is to be signaled when the vehicle's ignition key is in a locked position with position lights on, and of a second command signal corresponding in this case to the illumination of an element (3), by example vehicle frame, to obtain the desired results of the warning conditions and the activation of the light and / or acoustic signaling element (4).

In this example, the electrical connection details of the device have been omitted because they are irrelevant to the invention.

In the example shown in Figure 3, the control unit (1c) is constituted by a programmable microprocessor, provided with several signal inputs and outputs and a control and control software specific for this application.

5 By supplying the first and second signals to the microprocessor, in this case from the position lights (2) and from the panel lighting

or element (3) of the vehicle, said microprocessor evaluates them by activating the light and / or acoustic signaling element (4) when it determines, based on said signals, that the vehicle's ignition key is in the position of

10 lock with position lights on.

Once the nature of the invention has been sufficiently described, as well as a preferred embodiment, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the described elements may be

15 modified, as long as this does not imply an alteration of the essential characteristics of the invention that are claimed below.
