Abstract

The invention relates to a dynamic rudder which is used to steer vessels. According to the invention, a cylinder is incorporated into the lower part of the longitudinal centreboard or keel. Each end of the aforementioned cylinder is provided with a container which is half filled with water and the water is transferred from one container to the other by means of a pump. Moreover, the inventive device comprises a horizontal shaft which is perpendicular to the longitudinal axis of the vessel and parallel to the plane of the water.

Description

DYNAMIC TIMON APPLICABLE FOR SHIP GOVERNMENT

D E S C R I P C I ÓN

OBJECT OF THE INVENTION

The present specification refers to a request for an Invention Patent, corresponding to a dynamic rudder applicable to the government of ships, whose obvious purpose is to replace the traditional rudder of a ship of any type with a dynamic device.

FIELD OF THE INVENTION

This invention has its application within the industry dedicated to the manufacture of ships.

BACKGROUND OF THE INVENTION

The existence of an invention that has similar characteristics to those described herein is unknown by the applicant.

DESCRIPTION OF THE INVENTION

The dynamic rudder applicable to the government of ships proposed by the invention replaces the traditional rudder by incorporating a dynamic device.

More specifically, the dynamic rudder applicable to the government of ships subject to the Invention, it is constituted by a submerged cylinder and in connection with the hull, being located under the keel and properly centered, presenting an axis parallel to the longitudinal axis from bow to stern.

In the case of sailboats, the cylindrical device will be located below the orza, replacing the fixed counterweight of these ships, it should be noted that in this type of ships the rotation of the dynamic helm cylinder may be carried out by the effect of an internal electric motor or by means of propellers on the stern of the cylinder itself that will be activated by the thrust of the ship due to the wind.

DESCRIPTION OF THE DRAWINGS

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, a descriptive sheet is attached as an integral part thereof, with an illustrative character and non-limiting, the following has been represented:

Figure number 1.- Corresponds to a side elevation view of a sailboat incorporating the object of the invention relating to a dynamic rudder applicable to the government of ships.

Figure number 2.- Represents a front elevation view of the object shown in figure number 1.

Figure number 3.- Represents finally a sectional view of the dynamic rudder that is applied on ships mobilized by means of an engine

PREFERRED EMBODIMENT OF THE INVENTION

In view of figures 1 and 2, it can be seen how the dynamic rudder applicable to the government of ships, in this embodiment in sailboats, is constituted from the incorporation on the hull (2) of a sailboat (1) and specifically under the orza (4) obviously submerged in the water (3) a structural reinforcement (5) that holds a support body (6) inside which the cylinder (8) is located, cylinder that It acts according to its rotation as a dynamic rudder, indicating that the rotation of the cylinder can be effected by an internal electric motor or by means of propellers on the stern of the cylinder itself

(8), which will be activated by the thrust of the ship mobilized by the wind that is received in its rag or sail.

In figure 3, it is observed that the invention incorporates a cylinder (11) submerged and in connection with the hull as it has been represented in figures number 1 and 2, referenced with (5), but in the case of A conventional ship mobilized by an east engine will be positioned under the centered keel and its axis parallel to the longitudinal axis from bow to stern.

As in the previous case, the cylinder would be in constant revolution, indicating that from this graphic representation the cylinder has been referenced with (11) having two hollow tanks (12) and (13) located in the anterior and posterior zone, that is, in the bow and stern, that will be filled 50% with water or other liquid derived from it.

The cylinder has a pump (14) that has the mission of boosting the liquid from one tank to another.

The cylinder attached to the keel of the ship by a fixed connection located in its center, must be able to oscillate on a horizontal axis (15) perpendicular to the longitudinal axis (16) of the ship and parallel to the water plane.

For the government of the ship, in the case that they are sailing or mobilized by an engine, the water deposited in the cylinder from one tank to the other will be transferred, and if both are balanced the dynamic rudder will allow a linear displacement, but in case to pump more quantity to the front tank (12) the ship will make a starboard and port turn in case a greater amount is incorporated in the rear tank (13).

The steering of the ship ^{• 'will} be carried out only by means of this device that may be connected to a steering wheel on the control bridge or to the wheel of a seemingly conventional rudder on any type of ship.

This type of government of a ship, does not consume energy by lateral displacement of the water due to the rudder blade in the turn.

Claims

RE IVI ND IC AC IO NE S

1.- Dynamic rudder applicable to the government of ships, of those destined to be incorporated in the lower part of the hull of a ship (1), characterized in that the dynamic rudder is incorporated in the lower part of the hull (2) of a ship of sail (1), being configured as a cylindrical body (8) that is fixed at the bottom of the orza (4) by fixing it to the hull with a support element (5) that has support means (6) in its lateral zone, or it is incorporated in the case of a ship driven or mobilized by means of a motor such as a submerged cylinder (11) and in connection with the hull located below the keel, centered and with its parallel axis (15) to the longitudinal axis ( 16) from bow to stern being, both the cylinder (8) and the cylinder (15), in constant revolution, having deposits (12) and (13) located inside the bow and stern respectively, the tanks (12) being and (13) 50% filled holes with water or other liquid derived therefrom having the cylinder (8) or (11) internally a pump (15) to drive the liquid contained in a tank to the other or vice versa.

2.- Dynamic rudder applicable for the government of ships, according to the first claim, characterized in that the cylinder attached to the keel or to the hull of the ship by means of a fixed connection located in its center oscillates on a perpendicular horizontal axis the longitudinal axis of the ship parallel to the water plane.

3.- Dynamic rudder applicable to the government of ships, according to the first claim, characterized in that the steering of the ship is done by connecting the helm to a steering wheel located on the bridge or to the wheel of a seemingly conventional helm.

4.- Dynamic rudder applicable to the government of ships, according to the first claim, characterized in that in sailboats the rotation of the dynamic rudder cylinder can be carried out by means of an internal electric motor or by means of propellers installed in the stern of the cylinder (8 ) that will be triggered by the thrust of the ship due to the wind.
