Description

Catamaran boat with extendable sleeve

TECHNICAL SECTOR

The present invention relates to a construction system for a small and medium length boat, which includes a device for increasing and/or reducing the width or "beam" of a boat. It provides a wide beam for carrying out work in the sea, rivers or lakes, as well as a smaller beam suitable for transport by road or in containers, as well as to facilitate hibernation or storage of the boat.

The invention, from the point of view of its general characteristics, is included in the naval and logistics sector, for the construction of catamaran-type boats with the capacity to be used as a work boat, cleaning boat, transport of people and goods, diving , dredge, and also for tourist or leisure use.

STATE OF THE ART

In order to facilitate actions and specific tasks that need to be carried out during navigation, or to facilitate road transport, there are different types of folding and unfolding systems for boats.

The existence of boats, such as catamarans, with folding, detachable or similar elements is known in the art. For example, EP3725661 shows a catamaran whose sail can be dismantled, while WO2015160282 or KR20160129208 disclose two examples of a dismountable catamaran.

The main objective of the expandable beam system that is the reason for this document, which is going to be introduced in catamaran-type vessels (of medium length), is to achieve adequate beam dimensions for navigation and use in the form of an unfolded deck, and at the same time , achieve appropriate sleeve dimensions after the folded cover shape, so that transport, logistics and collection costs are minimized during periods of hibernation.

With regard to transport with a boat trailer, most medium-length boats for recreational or professional use are subject to compliance with current regulations for nautical trailers, which include specifications in relation to length, beam, weight and the height of the boat to be moved by road.

The characteristics and the specific ranspores by race that are listed and detailed in the General Vehicle Regulations approved by Royal Decree 2822/1988, of December 23.

Usually, a trailer widely used for small and medium-sized boats, are those that are commonly classified as "ball" type, which allow a maximum length of an articulated truck of 16.50 meters, the width should not exceed 2.55 meters, height 4.50 meters and a maximum weight of 18 tons in the case of a two-axle transport and 24 tons for a three-axle transport.

There is still a need to make an effective and safe system that can be incorporated into medium-length catamaran-type boats, so that the beam of the deck of said boat can be folded and unfolded with a practicable system, which with the deck unfolded, complies with all safety requirements necessary for navigation, and that with the cover folded, meets all safety requirements for road transport with ball tugs or any other permitted by road transport regulations, for transport in containers and to facilitate their lodging or storage during times of hibernation.

The applicant is not aware of a solution to this problem that can be compared with the present invention.

BRIEF EXPLANATION OF THE INVENTION

The invention consists of the construction of a catamaran boat, normally of small and medium length, with an extensible beam system that includes a series of structures and devices to be able to increase and/or reduce the boat's beam. In a preferred embodiment, it achieves maximum sleeve dimensions of 2.55m after folding. That is, suitable for road transport, or 2.30 m. for transport in containers or to facilitate hibernation or storage of the boat. On the other hand, after its extension or unfolding, it reaches approximate beam dimensions of 3.50 m., complying with maritime safety requirements in accordance with current regulations for navigation and to be able to carry out work in the sea, rivers or lakes.

The invention has been planned to be incorporated into any catamaran that is built in any material such as aluminium, wood, steel or fiberglass, or even with plastic materials.

During the construction of the ship, the structure of the length or length of the deck will be established with fixed and constant dimensions, while the esrucura e anc ooea manga ea cu era con e essema exens e is going to be able to fold and unfold the width of the boat in two different directions, having the following layout as a model:

1. - Beam unfolded for navigation: in an example or first configuration, beam dimensions of 3.50 meters, gives the catamaran great stability and achieves a deck surface suitable for carrying out numerous jobs.

2. - Folded beam for transport and logistics: in an example or first configuration, maximum beam dimensions of 2.55 meters, which allows easy normalized transport by road without being considered special transport, (such as a trailer or semi-trailer ). It can also be 2.30 m for container transport or adapt its dimensions to a sea container established according to international standards. These expandable beam vessels achieve a great competitive and economic advantage in relation to the transport of medium-sized vessels.

These expandable beam boats are going to achieve a huge reduction in their logistical transport costs, compared to the boats that have to be transported either by road using special transport, or by sailing. They also achieve a lower storage-hibernation cost as they can be stored on land compared to many ships that, due to their difficulty in moving by road and their large dimensions, have to shelter in port docking areas during hibernation periods.

In addition, the use of standardized transport for these expandable beam boats allows the degree of accessibility to be increased enormously to reach areas that are difficult to access by local and regional roads. It facilitates the launching of the boat in areas with difficult access such as lagoons and reservoirs, when, for example, a specific cleaning action has to be carried out.

Thus, the invention, in its essential variant, is a catamaran vessel comprising two or more hulls, the outer hulls being spaced apart from each other, by any type of technical solution (preferably transverse movement mechanisms), to achieve an extensible beam. In addition, it comprises a system for folding and unfolding the cover in width, such as mobile side covers by folding, telescopic, etc.

Extensible beam catamaran-type boats will include two large groups of devices, the first related to the base or central deck and the elements to make the approach or distance between the two hulls, and the second related to the devices and structures lateral extension mobiles, necessary to fix and block the structure of the base cover.

con nuac n secr en os os groups e spos vos e ssema e cu era extensible according to the most preferred embodiment:

Group 1.- Structure of the base deck and devices for the distance or approach of the hulls.

It consists of the following elements:

1.1. - Structure of the base cover.

A catamaran is a boat that has at least two parallel hulls of equal size. In the expandable beam catamaran, the structure of the base deck will be placed to remain fixed and unalterable on top of the two hulls, and it is the hulls that move closer to or further away from each other when the deck is folded or when the beam have its maximum extension disposition.

The base deck structure will provide not only a rigid base for the entire system to move from, but it will also have the mission of uniting all the equipment that makes up the boat, from the aft engines to the wheel steering wheel rudder, as well as among others, to the electrical wiring of each of its components.

1.2. - Clamp structures fixed to the two hulls.

The extensible system will have several clamp structures that will be fixed to each hull of the catamaran, and the number of which will depend on the length of the boat itself, the design of the clamp and the hull and the load capacity required on the deck.

The clamps will preferably have a flat shape at least in their upper part, and their arrangement will be fixed and embracing each hull of the catamaran. The clamps can have an anti-friction coating (teflon...) and/or wheels so that the traverse movement mechanism can easily slide over them.

1.3. - Transverse movement mechanisms

Devices that are going to be installed under the structure of the base deck of the catamaran, and that and/or guide or propel the hulls in their transverse movement away from or towards each other, manually or mechanically.

The number of transverse movement mechanisms is variable and will depend mainly on the weight and structure of the catamaran hulls, and their objective is to be able to guide or propel the hulls as a whole in their transverse movement away from or towards each other.

1.4. - Auxiliary units.

In the base deck structure there will also be devices formed mainly by other elements (pumps, tubes, actuators, electrical elements, etc.) that may be necessary for the boat.

rupo .- srucura e as cu eras m v es y spos vos e enace.

Once the maximum separation of the two hulls of the catamaran towards both ends has been achieved, the base deck structure will be fixed and blocked with the mobile extension structures on the sides.

The fixing and blocking of the base cover structure to the lateral extension devices will be carried out by combining the following elements.

2.1- Mobile lateral covered structures.

The extendable beam catamaran will have two mobile side decks placed on the port and starboard sides of the boat, oriented vertically. or exceeding that angle, when the catamaran is folded, and oriented in a horizontal position when the catamaran is unfolded, achieving the size of the deck, its maximum extension. The side covers can have their own railings, preferably folding, to be used in the horizontal position.

The side covers will move between their horizontal and vertical positions both mechanically (hydraulically, electrically, etc.) and manually.

Both mobile side covers will rotate between the horizontal position and at least one vertical position, to be in this first position horizontally aligned on both sides with the base cover structure. In this horizontal position, the side decks will be fixed to the base deck, blocking the entire system and making the entire structure of the boat work in solidarity.

2.2- Link devices.

The connection devices may be of a different nature depending on the type of vessel, and may be manual devices such as high-strength screws, bolts and nuts, twist-lock or similar mechanical devices, or any other suitable in terms of strength and capacity. to be released.

Twist-locks devices are used to fit and secure the position of numerous maritime elements, such as occurs for the lifting and transfer of containers.

The twist-lock type mechanical link devices will preferably be placed on the inside face of the two side covers when they are placed in their horizontal position. In the case of manual configuration, they will preferably be elements that go beyond the roof and can be placed from above the roof once it is placed in its horizontal position.

In the configuration of boats with mechanical link devices, the decks will have the link mechanisms in their inner part that allow the mechanical locking or unlocking of the structure.

Once both air lines are in position in the orzona, the liaison officers, either mechanically or manually, will fix the side decks to the receiving boxes, blocking the entire system and making the entire structure of the vessel work smoothly. solidarity.

The number of connection devices will depend, among other characteristics of the ship, on the length and the load capacity required on deck.

2.3- Reception boxes.

In vessels with mechanical connection devices such as twist-locks, the upper part of the clamping structures will have elements or reception boxes that allow the hammer or rotating part of the twist-locks to be housed, so that once activated block the structure.

In boats with manual connection devices, there will be guides or through holes.

MODES OF EMBODIMENT OF THE INVENTION

An example of embodiment of the invention, illustrative and non-limiting, in various applications is briefly described below.

The process of extension or deployment of the catamaran beam will be carried out in several stages, where the system devices will be located as follows:

apa .- caamar n is found in posc n e ranspore or pega o, g. and Fig. 5).

The hulls (1), the clamp structures (2), the transverse movement mechanisms (3) and the reception boxes (4) are housed under the structure of the base deck (5) of the catamaran, with the entire assembly of this embodiment some dimensions of The base cover (5) is fixed and unalterable and is placed on top of the two hulls (1). It provides a rigid base so that, during the deck extension or folding process, the hulls (1) can carry out a transverse movement away from or toward each other. In addition, it will serve as a base to place other equipment that makes up the boat: masts, engines, steering bridge, electrical wiring system, or any other equipment that the catamaran carries. These equipment can be on transverse guides to be able to move laterally, to port or starboard, with the cover unfolded.

The mobile side covers (6) will be in a vertical position, leaving the connection devices (7) on their outer face. They can also be folded down on the base cover (5). The mobile side covers (6) can have railings or other retention systems at the free ends, preferably folding, folding or removable.

The hulls (1) are located in their closest position between both.

The link devices (7), in this figure twist-locks, will be in the open position.

Stage 2.- Hull separation process (Fig.2 and Fig.3)

Next, the transverse movement mechanisms (3), manual or motorized, from their most collected position, begin to separate the hulls (1) transversely, until reaching their maximum separation length between them. The motorized transverse movement mechanisms (3) can be hydraulic, pneumatic, a series of rack-and-pinion systems, etc.

At the end of this intermediate stage, the hulls (1) are at their maximum separation length with respect to each other, the transverse movement mechanisms (3) are fully extended, and both the clamp structure (2) and the receiving boxes (4) are found and displayed on the sides of the base cover (5). Ideally, the boat has different separations of the hulls (1) that can be considered stable, depending on the use that will be made of the boat. In other words, the transverse movement mechanisms (3) can stop at intermediate points and not only at the ends.

Stage 3.- Fixing of the mobile side covers (Fig.4 and Fig. 6)

con nuac n the aerial cueras m v es a s to their horizontal position, where they rest already supported on the upper clamp structure (2) of the hulls (1), leaving the link devices (7) facing the reception boxes (4), ready to block the entire roof structure and make it solidary. In the manual configuration, the locking can be done by means of high resistance nuts and bolts (7), while in the configuration with mechanical link devices (7), it will be done by means of twist-lock mechanisms or similar.

When the entire deck structure is deployed and locked, the boat is already available for navigation, leaving the boat with established beam dimensions of around 3.50 meters, for example.

The process of folding the sleeve of the catamaran will be carried out in a staggered manner in the same 3 stages, but by means of an inverse procedure to the process of extending the sleeve, previously described.
