Preferably, the sail further comprises an access element (5) outside the base (3) for accessing the entrance (2), such as an access ladder extending vertically along the base (3). This invention provides a sail in which access to the interior of the sail is as simple and economical as possible, and the sail is suitable for vessels in areas with explosive atmospheres.

Description

Technical Field

[0001] The present invention relates to a sail, and more particularly to a rigid sail that allows access to the interior of the sail. Background Technology

[0002] It is known that a rigid sail is used to propel a ship, which consists of a slender body that is vertically positioned on the deck of the ship.

[0003] These rigid sails include a base for mounting them on the deck of a vessel, and may include an aerodynamic structure positioned near the end of the slender body if desired.

[0004] For maintenance or repair tasks, it is necessary to be able to access the interior of the rigid sail, for example, through a door located in the lower part of the elongated body.

[0005] In the case of tanker-type vessels (including those carrying oil, chemicals, LPG, LNG, etc.), these vessels have an Explosive Atmosphere Zone (ATEX) above deck; that is, an area where all items installed must be certified for explosive atmospheres, given the type of vessel. This complicates access to rigid sails, as compliance with these ATEX zones is necessary. Summary of the Invention

[0006] Therefore, the object of the present invention is to provide a sail in which access to the interior of the sail is as simple and economical as possible, and the sail is suitable for use on ships in areas with explosive atmospheres.

[0007] The sail of the present invention overcomes the above-mentioned disadvantages and presents other advantages as described below.

[0008] The sail according to the invention is described in claim 1, and the dependent claims include optional additional features.

[0009] Specifically, the sail includes a body having an entrance to the interior of the body, a base on which the body is located, and wherein the entrance is located on the side of the body.

[0010] Furthermore, the sail according to the invention preferably includes an entry element located outside the base for access to the inlet.

[0011] In this way, the sail can easily access the platform, and it allows the separation of the explosive atmosphere zone, which must be certified, from other zones (e.g., zones for installing electrical equipment).

[0012] Preferably, the entry element is an entry ladder that extends vertically along the base.

[0013] Furthermore, the sail according to the invention may also include an entry platform positioned around the base.

[0014] Advantageously, the entry platform has a circular crown shape in plan view, which allows circulation around the entire body of the sail, regardless of the location of the entrance to the body.

[0015] Furthermore, the sail according to the invention preferably includes an access ladder leading to the platform, which extends vertically along the base, allowing easy access to the platform from the ship's deck.

[0016] In addition, for safety reasons, the platform preferably includes external railings.

[0017] To facilitate access to the entrance to the main body of the sail, it preferably includes an additional ladder, such as a removable ladder, located between the platform and the entrance to the main body.

[0018] If desired, the sail according to the invention may include an aerodynamic structure located at the end of the body closest to the base, in which case the aerodynamic structure includes a hatch.

[0019] Advantageously, the platform is attached to the base; for example, the platform is welded to the base. Attached Figure Description

[0020] To better understand the statements already made, accompanying drawings have been provided, in which actual embodiments are shown schematically and by way of non-limiting example only.

[0021] Figure 1 This is a perspective view of a sail according to a first embodiment of the present invention;

[0022] Figure 2 This is a front view of the sail of the first embodiment of the present invention;

[0023] Figure 3 This is a front view of the sail of the second embodiment of the present invention; and

[0024] Figure 4 This is a perspective view of the sail of the third embodiment of the present invention. Detailed Implementation

[0025] These figures illustrate sails according to the invention. It should be noted that the sails according to the invention are preferably rigid sails, such as suction sails, Flettner rotors, or any other type of rigid sail.

[0026] The sail according to the invention comprises a body (1) that is elongated and provided with a lateral entrance (2) (e.g., an entrance door located on the side of the body (1)) for access to the interior of the body (1), as in Figure 1 As can be seen in the text.

[0027] The main body (1) is located on the base (3), which supports the main body (1) on the deck of the ship.

[0028] In addition, the sail includes an entry element (5) located outside the base (3) to access the entrance (2), which is preferably an entry ladder (5).

[0029] According to the first embodiment, the entry platform (4) is arranged around the base (3), and the entry platform (4) is preferably located at the upper part of the base (3). For the safety of the user, the entry platform (4) includes railings (6).

[0030] according to Figure 3 In the second embodiment shown, there is no entry platform, and entry is directly accessed via entry ladder 5.

[0031] The entry platform (4) preferably has a circular crown shape, such that the entry platform (4) completely surrounds the base (3).

[0032] Access to the platform (4) is achieved by an access ladder (5) positioned along the base (3), and in order to reach the entrance (2) of the main body (1), an additional ladder (7) located between the platform (4) and the entrance (2) is preferably used.

[0033] Although not strictly necessary, these illustrations show that the sail includes an aerodynamic structure (8) located at the end of the body (1) closest to the base (3). In this case, the aerodynamic structure (8) includes a hatch (9).

[0034] exist Figure 4 In the third embodiment shown, the sail does not include any access platform; instead, it is the aerodynamic structure (8) itself that performs the function of the previously described access platform.

[0035] In this way, in order to enter the interior of the main body (1) of the sail, the user climbs the ladder (5) toward the entry platform (4), and on the entry platform (4), the user can enter the additional ladder (7) (e.g., through the hatch (9) if there is an aerodynamic structure (8)) to reach the entrance (2) of the main body (1).

[0036] Although specific embodiments of the invention have been referenced, it will be apparent to those skilled in the art that the described sails are readily adapted and modified in various ways, and that all the details mentioned may be replaced by other technically equivalent details without departing from the scope of protection defined by the appended claims.
