DESCRIPTION:
BRIEF SUMMARY
The present invention concerns a device for the timed lighting of signal triangles provided on vehicles and of triangles indicating an emergency stop of a vehicle.
It is already well known that the triangles indicating an emergency stop are not visible in the dark, and that therefore they are often run over by arriving vehicles, with a consequent danger for the safety of people on vehicles having broken down.
In addition, the conventional rear signals of moving vehicles, such as the stops, the lights and the number-plate are not often very evident in conditions of low visibility, at night, with fog and during storms.
It is therefore the aim of the present invention to realize a device for obtaining a timed lighting, in following phases, of the structure and of the signals present on two kinds of emergency triangles, the first one provided on the vehicle and the second one that may be seen at distance when the vehicle has to stop for some reason.
The device according to the present invention will be described more in detail hereinbelow according to the enclosed drawings, in which a preferred embodiment is shown.
FIG. 1 shows a perspective view of the device for the timed distribution of the electric feeding of the various portions of the triangles.
FIGS. 2 and 3 respectively show the triangle placed on the vehicle and used in emergency stops.
Relating now to the details of the figures, the device according to the present invention comprises:
an electromechanical distributor 1, for the timed connection between the accumulator battery of the vehicle and those parts of the triangle that may be lighted;
a signal triangle 2 provided on the vehicle, comprising a bright background 4, a danger signal 5, a signal for overtaking on the left 6, a signal of forbidden direction 7 on the right, and a frame 8 with luminous points;
a triangle for emergency stop 3 with internal signals 9.
In an embodiment of the device according to the present invention, the electromechanical distributor consists of:
turning disc 10, placed into rotation by a small electric motor with a reducer 11;
three kinds of electric contacts 12, 13, 14, out of one piece with the upper plate of said disc 10, placed on offset planes for determining the contacts in successive phases with the terminals offset in height 15, 16, 17, that have the task of leading the electric feeding to the various parts of the triangles 2, 3;
a central contact 18 for the electric connection between the battery of the vehicle and the disc 10, so as to make the current arrive, by means of wires 19, to said contacts 12, 13, 14 which, following to the rotation, arrive in succession under the terminals 15, 16, 17 and from these the current arrives to the small lamps for lightening the elements 4, 5, 6, 7 and 8 of stop triangle 2 and, in alternative, to the elements 9 of the emergency stop triangle 3. As shown in FIG. 1, central contact 18 charges contacts 12, 13, 14 (e.g., a positive charge) such that the overhanging contacts of terminals 15, 16 and 17 become similarly charged when the terminal contacts come in contact with contacts 12, 13 and 14. The terminal contacts are thus placed in electrical communication with the battery at certain points of turning disc rotation. The charge periodically received through the terminal contacts is directed away from the base of a corresponding terminal to form part of a circuit used to energize the prongs of the signal lights shown in FIGS. 2 and 3. The oppositely charged line required to complete a circuit is shown extending into the interior of a terminal where it can be redirected and positioned together with the positively charged line in a suitable receptacle such as plug P (only one of three illustrated) used to receive the pronged plug of the signal lights. As shown, the contact surfaces have a curved outer periphery corresponding to the curved outer periphery of the turning disc and the turning disc rotates on a supporting base free from obstruction. The base also supports the upwardly extending terminals.
