Description

FIELD OF THE INVENTION

The present patent of invention relates to the integration of navigation lighting with mandatory signaling for watercraft, grouped in an integrating device, intended for the nautical sector, especially watercraft equipment.
International regulations to prevent collisions at sea, in its rules, advocates that the lights must be displayed from sunrise to sunset and in periods of limited visibility and the sector of visibility of the standard navigation lights regulates that sidelights (green to starboard and red to port): must have a sector of visibility of 112.5º, from the bow to 22.5º abaft the beam of its respective side; the masthead lights (continuous masthead lights) located at the center line of the watercraft must show a sector of visibility of 225º, from the bow to 22.5º abaft the beam on both sides of the watercraft; the white light (continuous white sternlight), located as close as possible to the stern, must be visible in a horizontal section of 135º, 67.5º for each side from the stern.
Watercraft signaling requires the study of its construction and purpose. The launch, for example, is a type of watercraft with a planing hull and its operation regime is different from conventional displacement watercraft. Due to the shape of the hull, moderate displacement and engine power range, the watercraft sails sustained by a vertical dynamic pressure which significantly reduces the wet area of the hull. The displacement hulls have limited maximum speed and, from a certain speed, variable according to length of the water line, the hull begins to climb the wave generated by its own movement. This causes lighting and signaling to be impaired in the usual setups.
Some watercraft models are equipped with a top frame, a structural reinforcement of the watercraft, with the purpose of pulling skis or wakeboards, setup for a radio antenna, radar reflector. It is, as well an usual place for the setup of watercraft lighting, and also a flag mast.
The watercraft are equipped with devices for sidelights, installed in the hull or ridge; sternlight installed at or near the stern, masthead lights installed on the mast, when present, or on the center line of the watercraft, for example.
Most watercraft have several lighting devices installed at different points of the watercraft, requiring different electrical fixtures for each point, adding costs to any maintenance. Another downside is the setup of canopies on the top frames, for example. Fixed device on this accessory, implies canopy improvisations and even cuts to suit the existing setup.

BACKGROUND OF THE INVENTION AND PRIOR ART

The integration of navigation lights and maritime signaling, radar deflector into a single device does not exist in the current market. Some partial solutions can be found by grouping only the sidelights.
An example of this grouping can be found in patent document nº. WO2005026610 , "IMPROVEMENTS IN AND RELATING TO SECTORED LIGHTS", published on 3/24/2005, reporting primary sectored lighting for use in the maritime industry by incorporating LEDs as a light source, distributed to a lens in conjunction with a positive (convex) curve that reflects on the elements and promotes a higher "arc of visibility" with weaker light scattering and accentuating the transition cut.
Although document WO2005026610 claims a device for enlarging the lighting by LED in sectored lights, the grouping has proved relevant to elucidate the technical concept intended in this patent application.
Integrating navigation lighting with marine signaling requires a refined technique, whose method requires the construction of a device having specific properties for such integration.

SUMMARY OF THE INVENTION

Massive research, testing and development were employed in the present device, herein entitled DEVICE FOR INTEGRATING LIGHTING AND SIGNALING FOR NAVIGATION PURPOSES, and which, in short, is endowed with integrated lighting and signaling for navigation purposes, having a front lighting assembly for the bow, a rear sternlight assembly; an upper anchor light assembly, a lighting assembly at the base of the transparent pole; a signaling assembly also arranged at the rear for stern lighting; starboard and port side signaling light assemblies pre-arranged in a central longitudinal portion of the watercraft, from the center to the rear, preferably on the top frame of the watercraft or a cover; a DEVICE FOR INTEGRATING LIGHTING AND SIGNALING FOR NAVIGATION PURPOSES, comprising a skid attached to the watercraft, on the top frame, a column or suitable support, having a split hull providing an inner support for attaching a radar deflection device, a support element for the flagmast and suitably arranged lights and signals on the outside, according to international navigation standards.
