Description

Ship comprising a defense and composite equipment to displace said defense

The present invention relates to a vessel comprising a defense and a composite team to displace said defense.

As is known, docking or anchoring for the mooring of a boat, such as a sailboat, is somewhat difficult and, in any case, it is not always a simple maneuver, especially if other boats or various structures are present in the parking area with which the mobile vessel must necessarily be placed in juxtaposition.

Think about when a boat is docking at a jetty or a dock of a port, or when it should be moored next to other boats already parked, in particular in a specific and limited area included between two of them.

The difficulty is mainly determined by the combination of two reasons: the unstable nature of the surface on which the vessel moves, which is the water, and the direction of the march with which these means of transport travel on such occasions, almost always the reverse, to get a replacement as correct, efficient and fast as possible.

Therefore, despite the care that the pilot has in the maneuvers, the moving vessel accidentally collides with neighboring bodies, with the obvious problems that this causes for the structural integrity mainly of the first, but also of the others.

In addition, to limit the risky implications mentioned above, the pilot performs slowly or frequently repeats the maneuvers, lengthening the time to finish them.

Problems related to the ruinous effects of accidental collisions also arise if the boat is already completely stopped, moored.

In fact, for this situation various types of equipment and components are available on the market, mainly inflatable defense elements or filled with spongy material, which eliminate or greatly limit the risks related to accidental and uncontrolled collisions between vessels.

Document DE 88 06 733 U1 describes a vessel comprising a defense and a composite team to displace said defense.

The fenders, which sometimes protrude from the hull of the vessel, and are sometimes directly attached to the jetty or pier, offer some protection to the vessel against accidental collisions only when the vessel is already moored, not being properly suited for situations in which The same continues to move.

Recently, however, the same applicant of the present invention has launched as a proposal on the market more studied and elaborate construction planning defense elements, including shock absorber bodies, sliding rollers and / or shock absorbers that allow the defenses, once arranged protruding from the vessel, effectively carry out its function even when the vessel is docking, therefore, still in motion.

However, protection defenses of the known type have some recognized disadvantages.

The main drawback of the known technique derives from the fact that the positioning of the aforementioned protection elements that protrude laterally from the boat is rather laborious, elaborate and prolonged in time, especially since it is usually done with the hands.

A second drawback of the known technique is constituted by some instability of the protection elements while still standing sideways to protect the boat from accidental collisions.

A final inconvenience, but no less important, of the state of the art in question is represented by the fact that, under conditions of non-use, the fenders obstruct the deck or other facilities or areas of the vessel.

The fenders are permanently installed only on motorized vessels and provided with a hull of a structure of certain strength and given dimensions, such as yachts, motorboats and the like.

The present invention aims to overcome the drawbacks of the prior art listed above.

In particular, the main objective of the invention is to provide a composite equipment to displace suitable defenses for the protection of ships, especially sailboats, during mooring and / or landing, through which it is possible to reduce, compared to the known technique, the time required to place these defenses in effective protection of the vessel itself.

A further objective of the present invention is to provide a vessel defense with greater stability than the equivalent known technique while in use.

Another objective of the invention is to make available a composite equipment to displace suitable defenses for the protection of boats, especially sailboats, during mooring and / or landing, rather compact and provided with high mechanical resistance, which can provide the defenses during its use of greater stability than equipment of the known type.

A final, but no less important, objective of the invention is to indicate a composite equipment to displace suitable defenses for the protection of vessels, especially sailboats, during mooring and / or landing, which may be permanently installed even in commonly known vessels. as the smallest in the nautical field, such as sailboats.

The aforementioned objectives are achieved by a vessel as defined in claim 1.

Other detailed characteristics of the vessel according to the invention are set forth in the corresponding dependent claims.

Advantageously, the vessel according to the invention allows protection defenses against accidental collisions to be placed outside said vessel more quickly and with less laborious maneuvers than the known technique.

More advantageously, the composite equipment of the vessel according to the invention provides the vessel's defense, under conditions of use, with greater stability than that allowed by known equipment or elements.

Equally advantageously, the invention allows the same defenses to be used both in motion and in mooring conditions.

Advantageously, moreover, the equipment composed of the vessel according to the invention can also be installed in existing rooms of specific vessels such as sailboats, remaining visible even when they are at rest, without affecting the aesthetic impact of the vessel.

In particular, the composite equipment to move the defense is mounted on the stern of a sailboat.

The vessel of the invention can also be a small vessel thanks to the high compactness and limited volume of the composite equipment, which allows the most unpleasant constructional components from the aesthetic point of view to be contained in the hull of the vessel, such as connecting cables and at least part of the support structures and the drive means.

In practice, therefore, in the embodiment described in this case, in which the first actuator 12 is a hydraulic cylinder, the connecting pin 23 is arranged at the free end of the rod 16, with which it is monolithic.

Preferably, the locking means 20 includes a longitudinal key, not shown, inserted in a pair of linear grooves 26, 27 facing and opposite each other, one made on the inner surface of the connecting ring 19 and the other on the outer surface of the tubular shaft 7.

In relation to the auxiliary group 5, it includes a connection sleeve 28 substantially in the form of L.

The tubular sleeve 28 is composed of a first tubular part 29, coaxial with the tubular shaft 7, in which it is made integral through joining means, for example a welding seam, and by a second tubular part 30, isolated from to the first part 29 and protruding orthogonally from it.

The figures cited heretofore show that, advantageously, the auxiliary group 5 also comprises gearing means, indicated globally with 31, coupled with the second tubular part 30 of the connecting sleeve 28 through support means, indicated globally with 32.

More specifically, the support plate 35 has an annular extension 35c protruding laterally from the second tubular part 30.

Preferably, but not exclusively, the auxiliary group 5 of the composite equipment 1 comprises a tubular protective housing 37 of mainly longitudinal development made, for example, of metallic material such as steel.

Figures 1-3 indicate that, on a first side edge, not shown, the tubular housing 37 is arranged proximally and coupled to the upper face 35b of the support plate 35.

Near said first lateral edge, the tubular housing 37 contains a central head 38, which protrudes from the upper face 35b of the support plate 35, and an annular locking nut 39 'interposed between the central head 38 and the tubular housing 37 , as shown in Figures 3-5.

The tubular housing 37 also encloses the gear means 31 connected to the support means 32.

In addition, the tubular housing 37 is disposed on a second side edge with a laminar cover 39 having a through slot 40 which communicates the inner volume of the tubular housing 37 with the exterior.

In a purely preferred manner, the gear means 31 presented above include a pair of bevel gears 41 which can be best seen in Figure 5.

The pair of bevel gears 41 is formed by a fixed pinion 42, coupled with the central head 38 of the support plate 35 and defining a second longitudinal axis X, and a toothed wheel 43, which meshes with the fixed pinion 42, coupled with a first transverse pin 44 defining a longitudinal direction Y1 orthogonal to the second X axis.

The first pin 44 is provided with ends fixed to the inner wall 37a of the tubular housing 37.

Beyond the first actuator 12 mentioned above, the drive means 3 includes a second linear actuator 45, contained in the tubular housing 37, on one side coupled with the inner wall 37a of said tubular housing 37 through third joining means , indicated in conjunction with 46, and on the other side operatively connected to the sprocket 43 through restriction means, marked globally with 47.

The second actuator 45, preferably a hydraulic cylinder as in the case of the first actuator 12, rotates the sprocket 43 around the second axis X defined by the fixed pinion 42 with an angle between 0o and 90o, so that the defense P turn on itself once a work position is reached.

The third joining means 46 comprise a second transverse pin 48, shown in Figure 6, which defines a second longitudinal direction Y2, parallel to the first direction Y1 defined by the first pin 44, and is equipped with ends fixed to the inner wall 37a of the tubular housing 37.

On the other hand, the restriction means 47 include a maneuvering rod 49, connected on one side with the second actuator 45 and on the other side with the first transverse pin 44, frontally to the sprocket 43.

More precisely, the operating rod 49 is connected to the end of the stem 50 of the hydraulic cylinder that constitutes the second actuator 45 and whose sleeve 51 is coupled with the second transverse pin 48.

According to the preferred embodiment of the invention described herein, the auxiliary group 5 also comprises means with lever action, indicated in conjunction with 52, partially contained in the tubular casing 37 and inserted in the through groove to protrude from said tubular casing 37 , as can be seen in figure 6.

The means with lever action 52 are coupled with the inner wall 37a of the tubular housing 37 through articulation means, disclosed in conjunction with 53, which include a third transverse pin 54 defining a third longitudinal axis Y orthogonal to the second X axis and provided with ends fixed to the inner wall 37a of the tubular protective housing 37.

The means with lever action 52, on the other hand, include a bracket formed 55 integrated by a first part 56, contained in the tubular housing 37 and having a first through hole 57 in which the third pin 54 is partially inserted, and a second part 58, located outside the tubular housing 37 and suitable to be coupled with the defense P through fixing means, numbered in conjunction with 59.

Preferably, but not necessarily, the fixing means 59 include an elastic damping joint 60, made of anti-vibration rubber, which is interposed between the defense P and the shaped bracket 55.

The elastic seal 60, which is substantially in the form of a uniform wheel, is combined with the bracket formed 55 through advance means, indicated in conjunction with 61 and including, for example, a percussion plate 62, integral with the extreme section of the second part 58 of the shaped bracket 55.

The percussion plate 62 is also firmly inserted in a surface cavity, not shown, made on a first face 60a, facing the laminar cover 39, of the elastic damping joint 60.

Advantageously, the fixing means 59 include pivoting means, not shown for convenience, which contribute, with the flexible joint 60, to cushion the accidental collisions suffered by the defense P and which also prevent the separation of the flexible joint 60 into case of breakage of the advancing means 61.

Preferably, but not binding, the pivoting means include a rod coupled with the second part 58 of the shaped bracket 55 and are provided with a spherical body applied on an articulation seat made at the midpoint of the first face 60a of the elastic seal 60.

The presence of the means with lever action 52 requires that the drive means 3 include a third linear actuator 63, also contained in the tubular housing 37.

The third actuator 63 is coupled on one side with the inner wall 37a of the tubular housing 37 through fourth connecting means, indicated globally with 64, and on the other side operatively connected with the shaped bracket 55 through of rotation means, globally disclosed with 65.

The third linear actuator 63, in the same way as the first actuator 12 and the second actuator 45 which preferably consist of a hydraulic cylinder, rotates the formed bracket 55 around the third Y axis with an acute angle, so that mainly the defense P turns up or down after reaching a working position.

In detail, the fourth joining means 64, similar to the third joining means 46, include a fourth cross pin 66 which, as shown in Figure 5, defines a third longitudinal direction Y3, parallel to the first direction Y1 defined by the first pin 44 and the second address Y2 defined by the second pin 48.

In addition, the fourth cross pin 66 is equipped with ends fixed to the inner wall 37a of the tubular housing 37 and is coupled with a first end 63a of the third actuator 63.

The rotation means 65 comprise a terminal pin 67 inserted in two through-coaxial through holes, not shown, made one in the first part 56 of the shaped bracket 55 and the other in a second end 63b of the third actuator 63.

More precisely, the terminal pin 67 is monolithic with the appendix of the stem 68 of the hydraulic cylinder that forms the third actuator 63 and whose sleeve 69 is coupled with the fourth cross pin 66.

Advantageously, the composite equipment 1 comprises control means, in this case, for example a hydraulic control unit, operatively connected with the drive means 3, to manage their operation.

Figures 7-15 schematically show the operation of the composite equipment 1, providing different and consecutive operational situations thereof and, on the other hand, of the defense P.

Based on the constructive details that form the composite equipment 1 of the invention, the movements associated with it are the following:

a) rotation of the tubular shaft 7 about the first longitudinal axis Z, applied by the first linear actuator 12 through the locking means 20;

b) rotation of the tubular housing 37 and the internal and integral components therewith, which belong to the

auxiliary group 5, around the second longitudinal axis X, applied by the second linear actuator

45 through the gearing means 31;

c) rotation of the shaped bracket 55 around the third Y axis, applied by the third linear actuator 63 through the rotation means 65.

The rotation around the first Z axis, referred to in point a), establishes a 90o rotation of the auxiliary group 5 and, with it, of the defense P which is thus arranged from the rest position of the Figure 7 to the final working position of Figure 10, passing through intermediate positions, of which two are shown in Figures 8, 9.

Under the working condition of Figure 10 of the fender P, the rod 16 of the hydraulic cylinder 12 is in the limit switch position, completely inside the sleeve 15.

If the position of the fender P in Figure 10 is not adequate to effectively protect the sailboat from unavoidable collisions with the other adjacent structures on a jetty or similar, the operator, maneuvering the control means, drives the second linear actuator 45 by setting rotating tubular housing 37.

It follows that the defense P revolves around itself according to what is shown, for example, by the sequence of figures 11-13, until it adopts the most suitable working condition for the incidental situation.

The rotation of the tubular housing 37 around the second X axis, referred to in point b) mentioned above, occurs at angles not wider than 90 °, in any direction of rotation, depending on the initial adjustments of The operating parameters.

When, from the position of Figure 10, the rotation around the second X axis has reached the value of 90 °, the rod 50 of the hydraulic cylinder 45 is in the limit position, fully retracted into the jacket 51.

The composite equipment 1 of the invention allows an additional adjustment in case, for example, the sailboats on which it is mounted are, with respect to the free surface of the water at the mooring, lower or higher than other structures or boats adjacent.

In this case, the order of the control means causes the actuation of the third actuator 63, which rotates the shaped bracket 55 around the third axis Y, so that the defense P rotates adopting working conditions as shown in the figures 13-15

In particular, Figure 13 shows the working conditions of the defense P suitable for the case in which the vessel B must be protected from potential collisions with neighboring structures lower than the free surface of the water, while the working condition of the fender P of figure 14 (and the enlargement of figure 15) is suitable when said neighboring structures, such as yachts, are taller than the boat B with respect to the water-free surface.

Obviously, the displacement of the defense P can occur when only part of the actuation means 3, or all of them, and the corresponding orientation means 2 of the composite equipment 1, and each of the rotations around the actuators are actuated. respective X, Y and Z axes can be stopped at points that differ from those indicated in the figures, depending on the application needs.

In contrast to equivalent equipment of the known type, then the composite equipment 1 of the invention allows various adjustments of the position of the defense to be made P.

It is very reasonably possible to say that the composite equipment 1 of the invention allows to substantially orient, as desired, the defense P and place it to protect the vessel B against accidental collisions in any situation: this is mainly thanks to the multiple adjustments offered by the orientation means 2 and drive means 3.

By virtue of what has been stated above, it is therefore understood that the composite equipment to displace adequate defenses for the protection of ships, especially sailboats, during mooring and / or landing, object of the invention, achieves the objectives and get the benefits mentioned previously.

In the execution phase, changes can be made to the composite equipment of the invention consisting, for example, in a constructive arrangement of the orientation means different from that described above and illustrated in the following drawings.

Beyond this, there will be other solutions of the invention in which the drive means will be different from those mentioned previously, for example linear actuators of the pneumatic type.

In addition, the drive means may be controlled differently from that indicated above, which does not affect the advantages provided by the present patent.

The vessel of the invention can be any vessel, not necessarily a sailboat, and the composite equipment is not exclusively mounted aft, but in any suitable position for this purpose and, also, in any number of models, depending on the size of the vessel itself. boat and constructive choices.

Finally, it is evident that many different variations of the vessel in question can be made, without leaving, for this reason, the scope of the claims, as it is evident that, in the practical implementation of the invention, the materials, the shapes and the Sizes of the details illustrated can be any, depending on the needs, and can be replaced by technically equivalent ones.
