Abstract

Mast for boat, which is sustained in cooperation with both bow and stern stays on boats with deck or without decks; characterized in that it comprises two, symmetrical branches joined together by the top of the mast and diverging in the downward direction, and in the lower part of which are provided mast feet intended to be fixed in lateral areas of the vessel transversely to the line of the bay, in order to work at tension the windward branch and to compress the leeward branch.

Description

Mast for boat.

Object of the invention

The present invention relates to a mast for boat that improves the transmission of forces to the hull, improves robustness and maneuverability and frees up space in the boat

Background of the invention

Currently sailing vessels they comprise one or more masts installed in the creaking line (centered longitudinally with the boat) and that sustain through its embedment on the roof of the boat and its support by steel braces: towards the bow and stern by bow and stern stays, and laterally by the shrouds, passing these through spacer spreaders of the mast to be fixed laterally on the sides of the boat

This configuration presents some inconvenience First the masts occupy a space both on the deck and in the cabin under cover, case of exist. On the other hand, they are more likely to split when they suffer greater torsion forces. And finally, the windward obenque withstands virtually all lateral tension (in addition to the joint from the mast to the hull) while the leeward shroud does not works, which defines a critical element in the tooling and equally prone to breakage, which requires detailing its maintenance.

Description of the invention

The boat mast of the invention has an optimal constitution that remedies the inconveniences described.

According to the invention, the mast has symmetric constitution based on the branches linked together firmly by its top and divergent downward to look at two mast feet provided transversely to the creaking line on both sides of the boat, preferably on deck on both sides, cooperating in the Mast fixing also two bow and stern stays.

In this way, on the one hand, the shrouds and their fragility and maintenance, and on the other hand get a better transmission of forces to the hull of the vessel, since they work both the windward branch (to traction) and leeward (compression) on both sides of the ship.

There are also planned crossbars of reinforcement that relate both mast branches to heights convenient.

Another advantage of the mast of the invention it consists in that the warlike center (center resulting from the wind pressures exerted on the sail) falls in the center of the helmet, and there is no destabilizing force, favoring government.

In addition the mast of the invention is lighter that

an equivalent conventional mast since, to despite carrying two branches and therefore longer tube length, is

much less thickness needed to support lower torsion forces.

Brief description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to an example preferred practical implementation of it, is accompanied as integral part of that description, a set of drawings where with an illustrative and non-limiting nature, what has been represented next:

Figure 1 shows a perspective view of a vessel provided with the mast of the invention.

Figure 2 shows a plan view of the boat of figure 1.

Figure 3 shows a detail of a foot of mast for the mast of the invention.

Figure 4 shows a detail of the top of mast of the invention.

Description of a practical embodiment of the invention

The mast (1) for boat of the invention comprises two branches (2), (3) tubular joined together firmly on the mast top by the

corresponding welding (4), and that diverge in  descending direction ending in two mast feet (5)

intended to look at the proximity of both sides (6), (7) of the boat (8), and that in this example you fixed by counterplates (9) screwed under the

deck (10) of the boat. In small boats, or without deck, the Mast feet can be fixed directly on the sides of the boat

In the fixation and stabilization of the mast two bows of bow (11) and stern (12) also cooperate.

In intermediate and convenient areas of the mast reinforcements are provided consisting of one or more crossbars (13) that relate both branches (2) and (3), whose crossbars can be used for the installation of equipment such as anemometers, radars, etc.

These branches (2) and (3), and also the crossbars (13), preferably adopt aerodynamic section, by oval example.

As for the mast feet (5), very preferably they will be very close to the sides and ideally coinciding with transverse bulkheads (14) of helmet reinforcement of the boat. In this way three effects are achieved advantageous, which consist in favoring the transmission of forces to the hull, clear deck and cabin, and save materials.

Claims (4)

1. Mast (1) for boat (8), which is supported in cooperation with two bow (11) and stern (12) stays on vessels with deck or without deck; characterized in that it comprises two branches (2), (3) symmetrical joined together by the mast stop and divergent downwards, and at the bottom of which are provided with two mast feet (5) intended to be fixed in lateral areas of the boat transversely to the creaking line, in order to work tension the windward branch and compress the leeward branch. 2. Mast (1) according to claim 1 characterized in that some crossbars (13) are provided that relate both branches (2) and (3) at convenient heights. 3. Mast (1) according to claim 1 characterized in that the mast feet (5) are arranged in areas preferably very close to the sides and ideally coinciding with transverse bulkheads (14) for reinforcement of the helmet. 4. Mast (1) according to claim 3 characterized in that in vessels with deck the mast feet (5) are preferably fixed by counter plates (9) screwed under the deck (10).
