Definitions
- the present invention relates to a landing gangway, particularly for boats, with increased use safety.
- the landing gangway with increased use safety of the invention which preferably but not necessarily includes construction elements that are telescopically coupled to each other, can be installed for example on the boat in such a way as to remain outside of the boat (therefore it can be seen from the outside) or can be housed inside a housing provided in the hull of the boat (hidden from view) when it is in a rest or non-use position.
- landing gangways are accessories for the boating that are used to allow a simple transit for persons or objects between the boat and the dock.
- the landing gangways that are available on the market comprise a transit walkable platform which generally has a rectangular plan view and, in particular, a width such as to allow the transit of a single person and a length that allows to moor the boat at a safe distance from piers, docks or wharfs.
- Said landing gangways can be manufactured in many ways, as well as many materials can be used to made their parts; moreover, said materials are more and more sought both for their performances and aesthetic views, especially in view of the value of structures in which they are installed.
- the choice of the construction materials is based, in fact, on technical, functional and aesthetic assessments: in particular, stainless steels, anticorrosion light alloys, tempered glasses, precious woods, such as teak, and/or technological polymers are used in order to significantly increase the technical features and the aesthetic qualities of the landing gangways.
- manual and automatic gangways are known; they are raised and/or rotated in a landing position, between the boat and the dock, either manually or with movements implemented by linear hydraulic cylinders or by electrical drives.
- the structure of a known landing gangway also usually includes a plurality of gripping and/or supporting rods (so-called “candlesticks”), which are coupled at at least one of the lateral edges of the transit platform and which are connected by cables or rigid and/or tensioned cords to act if necessary to help and support the people who walk the gangways to or from the boat.
- gripping and/or supporting rods so-called "candlesticks”
- the gripping and/or supporting rods When the landing gangway is in a rest position, the gripping and/or supporting rods are parallel to the longitudinal axis defined by the walkable transit platform and are contained in the encumbrance of said platform, while, when the landing gangway is in a use position, the gripping and/or supporting rods protrude from at least one of the side edges of the walkable transit platform according to a direction which, depending on the embodiments, is orthogonal or oblique to the plane of the walkable platform.
- the gripping and/or supporting rods project outside in the central portion (and not in the ends) of at least one of the side edges of the transit platform.
- This feature forces people, who are trying to safely walk from the dock or pier to the transit platform of the landing gangway, to stretch excessively the arms in order to catch at least one of the rods or at least one of the ropes; consequently, their body protrudes dangerously towards the water, causing substantial risks of falling in the water.
- a further drawback of the known landing gangways which is a direct consequence of what has just been said referring to the disposal of the gripping rods when they are in a use position, is constituted by the fact that said landing gangways cannot be used by children, older and/or incapacitated people that are not accompanied by other adults people.
- a known landing gangway having the technical features of the preamble of the appended claim 1 is also disclosed, for example, in DE3310460A1 .
- the present invention seeks, therefore, to obviate the above mentioned drawbacks of the prior art.
- a first object of the present invention is to indicate a landing gangway with increased safety of use, particularly for boats, which will make it easier and more practical and comfortable, with respect to the known landing gangways, the boat entrance and exit by the user.
- the landing gangway of the present invention has, especially during a boarding, a more practical and comfortable use and a safer utilization with respect to known landing gangways.
- the landing gangway of the invention reduces therefore, with respect to the known landing gangways, the risks for people of accidental and dangerous falls in the water during the access to the boat from a pier or a dock.
- the landing gangway of the invention can be used autonomously by any person, including a child, thanks to the increase in the safety of use with respect to the known gangways.
- the landing gangway of the invention achieves the above advantages substantially without affecting the production costs, thus showing competitive selling prices.
- the landing gangway 1 comprises a first transit platform 2 that mainly follows a longitudinal axis Z and defines an upper plane 3 that is walkable by people during transit to or from the boat.
- the landing gangway 1 comprises a gripping and/or support front rod 4 that is coupled to one of the side edges 2a, 2b of the first transit platform 2 in correspondence with the access end 2c of the first transit platform 2 and that is operatively connected to actuating means, generally indicated with 5, able to rotate it from/to a rest position, according to which the gripping and/or support front rod 4 lies along the longitudinal axis Z of the first transit platform 2, to/from an operating position, according to which the gripping and/or support front rod 4 protrudes upwardly from one of the side edges 2a, 2b of the first transit platform 2, in a direction Y crossing the longitudinal axis Z of the first transit platform 2, in order to provide a safe hand grip for people.
- the front rod 4 protrudes upwardly in a direction orthogonal to the longitudinal axis of the first transit platform 2, while in the rest position the front rod 4 is flanked externally to one of the side edges 2a, 2b of the first transit platform 2.
- actuating means 5 of the landing gangway 1 of the invention are of the manual or automatic type; in the latter case, they are controlled by control means comprising a central processing unit which is available to the operator who controls their operation.
- the landing gangway 1 also comprises a second transit platform 6, which is slidingly coupled to the first transit platform 2 so as to identify a first position, according to which the first platform 2 is unusable and is substantially housed in the encumbrance of the second platform 6, and a second position, according to which the first platform 2 protrudes along the longitudinal axis Z from the second platform 6, becoming an extension of the second platform 6, which in turn identifies an upper surface 7 that can be walked by people.
- a second transit platform 6 which is slidingly coupled to the first transit platform 2 so as to identify a first position, according to which the first platform 2 is unusable and is substantially housed in the encumbrance of the second platform 6, and a second position, according to which the first platform 2 protrudes along the longitudinal axis Z from the second platform 6, becoming an extension of the second platform 6, which in turn identifies an upper surface 7 that can be walked by people.
- the first transit platform 2 is telescopically coupled to the second transit platform 6; this occurs thanks to guide means, which are not shown for simplicity and which are interposed between the first platform 2 and the second platform 6.
- the actuating means 5 are operatively connected to the first transit platform 2 so as to place it between the above mentioned first and second positions, as well as between the rest position and the operating position.
- the first and the second platforms may be coplanar with one another in said second position, thanks to elevation/lowering means: in this way, the landing gangway of the invention prevents the risks of accidental stumbling and subsequent fall for people, thus making it more secure than the known landing gangways for boats.
- the landing gangway 1 of the present invention includes a gripping and/or support rear rod 32, that is coupled to one of the side edges 6a, 6b of the second transit platform 6 and that is operatively connected to the gripping and/or support front rod 4 by means of flexible cables, not shown for the sake of simplicity, which are able to assume the same operating position of the front rod 4 in the rest and operating positions.
- the front rod 4 is coupled to the first transit platform 2 through rotation means, generally indicated with 8, cooperating with the actuating means 5 for selectively placing the front rod 4 between the rest position and the operating position.
- the rotation means 8 are placed at the access end 2c of the first transit platform 2, as shown in the enlarged detail of figure 2a .
- the rotating means 8 comprise a shaft 9 which identifies a linear axis of rotation X perpendicular to the longitudinal axis Z of the first transit platform 2.
- the shaft 9 is also coupled to the lower end 4a of the front rod 4 through fixing means, generally indicated with 10 and comprising, for example, an assembly ring nut 33 and a cap with a nut screw 34.
- the shaft 9 is essentially contained between the side edges 2a, 2b of the first transit platform 2 from which protrudes only for a first end pin 11 inserted into a through hole, not shown, which is provided in one of said side edges 2a, 2b of the first transit platform 2 and which is partially contained in a coupling sleeve 12 associated with the lower end 4a of the front rod 4.
- the shaft 9 has a partially squared or grooved outer surface 9a in order to increase its coupling capability with the other components which indirectly connect it to the second transit platform 6, as will be better clarified in the following.
- the coupling sleeve 12 is generally welded to a folded end portion 13 of the front rod 4.
- FIG. 3a shows that the assembly ring nut 33 is externally coupled to the coupling sleeve 12.
- the landing gangway 1 includes, in correspondence of the rotation means 6, elastic means, which are generally indicated with 14 and are associated with said rotation means 6: the elastic means 14, shown in the attached figure 3a , have the function to counteract the action of the actuating means 5, thus resulting progressively compressed up to a load condition, when the front rod 4 passes from the rest position to the operating position, and progressively released up to a release condition, when the front rod 4 passes from the operating position to the rest position.
- the elastic return means 14 comprise for example a torsion spring 15 which is disposed around the shaft 9.
- actuation means 5 they are of the automatic type and include a linear actuator 16, shown in the attached figure 2 , which:
- the linear actuator 16 for example of the hydraulic type, comprises:
- cylindrical chamber of the linear actuator 16 is coupled to the lower wall 6c of the second transit platform 6 only for the specific structure of the landing gangway 1 as described herein.
- the cylindrical chamber of the linear actuator can be coupled to the lower wall of the first transit platform or to the inner wall of a housing of the boat or of a generic access infrastructure where the landing gangway claimed herein is fixed.
- lever system 17 comprises:
- the shaped lever arm 19 has a linear wall 22 adapted to be oriented towards the outside of the first transit platform 2 when the front rod 4 is in the operating position: this structure arrangement avoids the mechanical interference of the shaped lever arm 19 with the connecting hinge 20 in said operating position of the front rod 4.
- the shaped lever arm 19 also has a through opening 23, preferably squared, in which a second end pin 24 of the shaft 9 is inserted.
- the through opening 23 is coaxial with the through hole formed in one of the side edges 2a, 2b of the transit platform 2 and with the connection sleeve 12 which is provided at the lower end of the front rod 4.
- the shaped lever arm 19 In the rest position of the front rod 4, shown in figure 2b , the shaped lever arm 19 is partially housed in the connecting hinge 20, while in the operating position of the front rod 4, shown in figures 2, 2a and 3 , the shaped lever arm 19 is pivoted to and protrudes from the connecting hinge 20, thus identifying a direction which is mainly oblique.
- Figure 2 also shows that the rigid bar 21 slides along a peripheral linear seat 25, which communicates with the outside through an outlet mouth 26 formed in the second transit platform 6, in which the rigid bar 21 is fully housed when the front rod 4 is in a rest position.
- the rigid bar 21 is also provided with a mechanical stop 27 near a second end 21b; the mechanical stop 27 is applied to the outer wall 21c of the rigid bar 21 and is coupled with abutment means, generally indicated with 28, which are placed in correspondence with the outlet mouth 26 of the peripheral linear seat 25 so as to stop the sliding of the rigid bar 21 along the linear axis Z'.
- the abutment means 28 comprise a bush 29, provided with a head 30 fixed to the front edge 6d of the second transit platform 6 so as to surround the outlet mouth 26.
- the sleeve 29 is also provided with a shank 31, which is inserted in the peripheral linear seat 25 and which is coupled with the stop element 27 so as to stop the axial movement of the rigid bar 21, as shown in the enlarged detail of figure 2a .
- FIG. 8 show another possible embodiment of the invention, in which the landing gangway, which is generally indicated with 50, differs from the gangway 1 previously described mainly in the structure of the lever system, generally indicated with 58, by means of which the linear actuator 57 cooperates with the rotation means, generally indicated with 56, so as to place the front rod 52 respectively between the rest position and the operating position.
- the lever system 58 includes:
- the shaped lever body 59 has a U-shaped structure, in side view, and a pair of opened recesses 61 facing each other and communicating with the outside.
- the pawl 60 is welded to a transverse bridge 62 which separates it from the linear actuator 57 to which the transverse bridge 62 is, in turn, welded.
- Another feature that distinguishes the landing gangway 50 from the landing gangway 1 refers to the structure of the rotation means 56, which comprise the above mentioned shaft 63 protruding from both opposed side edges 51a, 51b of the first transit platform 51, being provided with end pins 64, 65 inserted in respective through holes 66, 67 coaxial with each other and formed in said side edges 51a, 51b of the first transit platform 51.
- the landing gangway 50 of the invention also comprises a plurality of rear rods 54, which are uniformly distributed on one of the side edges 53a, 53b of the second transit platform 53 to which the first transit platform 51 is preferably coupled in a telescopic way.
- the landing gangway 1 is normally in the functional position shown in the enlarged detail of figure 2b , in which the front rod 4 and the rear rod 31 have a rest position and the first transit platform 2 is housed in the encumbrance of the second transit platform 6 when it has the above mentioned first position.
- the landing gangway 1 is moved for example towards the dock or the pier so that people are able to board the boat or any other walkable structure.
- the operator through the control means, actuates the actuation means 5 and particularly the linear actuator 16, whose stem exits from the cylindrical chamber and progressively pushes the first transit platform 2 along the longitudinal axis Z so as to place it outside the second transit platform 6.
- the thrust which is given to the first transit platform 2 through the stem of the linear actuator 16 causes the simultaneous traction along the linear axis Z', parallel to the longitudinal axis Z, of the rigid bar 21 of the lever system 17, by means of which the linear actuator 16 is coupled with the rotation means 8 for selectively placing the front rod 4 between the rest position and the operating position.
- the rigid bar 21 thus progressively protrudes from the peripheral linear seat 25 of the second transit platform 6 till when the stop element 27 counteracts the bush 29 of the abutment means 28 placed in correspondence of the outlet mouth 26 of the peripheral linear seat 25.
- the thrust that the stem of the linear actuator 16 keeps on giving to the first transit platform 2 causes the movement of the shaped lever arm 19 which, by rotating in correspondence of the pivot 35, causes a clockwise rotation of the shaft 9 about the linear axis of rotation X and, in turn, a clockwise rotation of the rod front 4 starting from the rest position.
- the shaped lever arm 19 In the operating position of the front rod 4, the shaped lever arm 19 has the operating condition shown in figures 2a , 3 and 3a , while the return elastic means 14 are compressed to counteract the action of the linear actuator 16 of the actuation means 5.
- the operation of the landing gangway 50 of the invention essentially corresponds to the operation of the landing gangway 1, with the only difference constituted by the mechanical system of movement of the lever system 58.
- the axial movement of the stem 68 of the linear actuator 57 belonging to the actuation means 55 causes a first significant extension of the first transit platform 51 from the second transit platform 53, through sliding along the longitudinal axis Z.
- the axial movement of the stem 68 of the linear actuator 57 causes the connection between the transverse bridge 62 (provided at the front end 57a) and a first opened recess 61 of the shaped lever body 59 and the simultaneous contrasting between the pawl 60 and the inner wall 59a of the shaped lever body 59, and the counterclockwise rotation of the shaft 63 about the linear axis of rotation X for a maximum angle of about 90°.
- the axial movement of the stem 68 slightly goes on even after the front rod 53 has reached the operating position, so that the front edge 68b of the stem 68 counteracts the inner surface 69a of the plate 69 of the first transit platform 51.
- the first transit platform 51 After reaching the end position of the stem 68, the first transit platform 51 is in the above mentioned second position and is ready for use; advantageously, it is also coplanar to the second transit platform 53 thanks to the presence of elevation/lowering means, not shown, which are interposed between the two platforms 51 and 53.
- suitable return elastic means generally indicated with 70 and coupled with the shaft 63 of said rotation means 56, counteract the action of the actuating means 55.
- a first side edge of the first transit platform has a through hole and the second side edge opposite the first side edge has a respective through hole coaxial with the previous one, while the rotation means may include a single shaft or two different shafts and the return elastic means may optionally include a torsion spring for each shaft.
- the gripping and/or support front rod may protrude upwardly from at least one of the side edges of the first transit platform, according to a direction which is not necessarily orthogonal, but which is oblique, with respect to the longitudinal axis of the first transit platform, so as to be available to the hand grip of people.

Description
- The present invention relates to a landing gangway, particularly for boats, with increased use safety.
- The landing gangway with increased use safety of the invention, which preferably but not necessarily includes construction elements that are telescopically coupled to each other, can be installed for example on the boat in such a way as to remain outside of the boat (therefore it can be seen from the outside) or can be housed inside a housing provided in the hull of the boat (hidden from view) when it is in a rest or non-use position.
- It is known that landing gangways are accessories for the boating that are used to allow a simple transit for persons or objects between the boat and the dock.
- The landing gangways that are available on the market comprise a transit walkable platform which generally has a rectangular plan view and, in particular, a width such as to allow the transit of a single person and a length that allows to moor the boat at a safe distance from piers, docks or wharfs.
- Said landing gangways can be manufactured in many ways, as well as many materials can be used to made their parts; moreover, said materials are more and more sought both for their performances and aesthetic views, especially in view of the value of structures in which they are installed.
- The choice of the construction materials is based, in fact, on technical, functional and aesthetic assessments: in particular, stainless steels, anticorrosion light alloys, tempered glasses, precious woods, such as teak, and/or technological polymers are used in order to significantly increase the technical features and the aesthetic qualities of the landing gangways.
- Furthermore, manual and automatic gangways are known; they are raised and/or rotated in a landing position, between the boat and the dock, either manually or with movements implemented by linear hydraulic cylinders or by electrical drives.
- The structure of a known landing gangway also usually includes a plurality of gripping and/or supporting rods (so-called "candlesticks"), which are coupled at at least one of the lateral edges of the transit platform and which are connected by cables or rigid and/or tensioned cords to act if necessary to help and support the people who walk the gangways to or from the boat.
- When the landing gangway is in a rest position, the gripping and/or supporting rods are parallel to the longitudinal axis defined by the walkable transit platform and are contained in the encumbrance of said platform, while, when the landing gangway is in a use position, the gripping and/or supporting rods protrude from at least one of the side edges of the walkable transit platform according to a direction which, depending on the embodiments, is orthogonal or oblique to the plane of the walkable platform.
- However, the prior art landing gangway that are just briefly described have still some known drawbacks, that are related to the arrangement of the gripping and/or supporting rods when the gangway is in a use position.
- In fact, when the landing gangway is in a use position, the gripping and/or supporting rods project outside in the central portion (and not in the ends) of at least one of the side edges of the transit platform.
- This feature forces people, who are trying to safely walk from the dock or pier to the transit platform of the landing gangway, to stretch excessively the arms in order to catch at least one of the rods or at least one of the ropes; consequently, their body protrudes dangerously towards the water, causing substantial risks of falling in the water.
- A further drawback of the known landing gangways, which is a direct consequence of what has just been said referring to the disposal of the gripping rods when they are in a use position, is constituted by the fact that said landing gangways cannot be used by children, older and/or incapacitated people that are not accompanied by other adults people.
- It is also clear that the above mentioned drawbacks occur similarly even when people leave the boat by walking on said landing gangways.
- A known landing gangway having the technical features of the preamble of the appended
claim 1 is also disclosed, for example, inDE3310460A1 . The present invention seeks, therefore, to obviate the above mentioned drawbacks of the prior art. - In particular, in fact, a first object of the present invention is to indicate a landing gangway with increased safety of use, particularly for boats, which will make it easier and more practical and comfortable, with respect to the known landing gangways, the boat entrance and exit by the user.
- Within the above object, it is a main task of the invention to make a landing gangway with increased use safety, particularly for boats, which makes safe for people the boat entrance and exit with respect to the known landing gangways.
- It is another task of the present invention to provide an increased use safety landing gangway, particularly for boats, which is autonomously usable from any person under conditions of greater safety with respect to the prior art gangways.
- It is a further object of the invention to make an increased use safety landing gangway which can be installed in any type of boats.
- It is a further object of the invention to provide an increased use safety landing gangway, particularly for boats, that, despite the improvements over the prior art, has low manufacturing time and costs.
- The above mentioned objects are achieved by means of an increased use safety landing gangway, particularly for boats, as claimed in the attached
claim 1. - Further technical features of the increased use safety landing gangway of the invention are set forth in the following dependent claims. Advantageously, the landing gangway of the present invention has, especially during a boarding, a more practical and comfortable use and a safer utilization with respect to known landing gangways.
- This is due to the presence of a front rod, which is placed at the front end of the walkable transit platform and which, in a use position, is available for the hand grip of people.
- Still advantageously, the landing gangway of the invention reduces therefore, with respect to the known landing gangways, the risks for people of accidental and dangerous falls in the water during the access to the boat from a pier or a dock.
- Equally advantageously, the landing gangway of the invention can be used autonomously by any person, including a child, thanks to the increase in the safety of use with respect to the known gangways.
- Also advantageously, the landing gangway of the invention achieves the above advantages substantially without affecting the production costs, thus showing competitive selling prices.
- Further characteristics and features of the invention will become more clear from the following description, relating to a preferred embodiments of the increased use safety landing gangway, particularly for boats, herein claimed, which is given for indicative and illustrative, but not limitative, example and with reference to the attached drawings in which:
-

figure 8a is an enlarged detail offigure 7 . - The increased use safety landing gangway of the invention, which is preferably installed in boats, is shown in
figures 1 and 2 where it is generally indicated with thereference number 1. - The
landing gangway 1 comprises afirst transit platform 2 that mainly follows a longitudinal axis Z and defines anupper plane 3 that is walkable by people during transit to or from the boat. - According to the invention, the
landing gangway 1 comprises a gripping and/or supportfront rod 4 that is coupled to one of theside edges first transit platform 2 in correspondence with theaccess end 2c of thefirst transit platform 2 and that is operatively connected to actuating means, generally indicated with 5, able to rotate it from/to a rest position, according to which the gripping and/or supportfront rod 4 lies along the longitudinal axis Z of thefirst transit platform 2, to/from an operating position, according to which the gripping and/or supportfront rod 4 protrudes upwardly from one of theside edges first transit platform 2, in a direction Y crossing the longitudinal axis Z of thefirst transit platform 2, in order to provide a safe hand grip for people. - More precisely, in this embodiment, in the operating position the
front rod 4 protrudes upwardly in a direction orthogonal to the longitudinal axis of thefirst transit platform 2, while in the rest position thefront rod 4 is flanked externally to one of theside edges first transit platform 2. - It should be also noted that the actuating means 5 of the
landing gangway 1 of the invention are of the manual or automatic type; in the latter case, they are controlled by control means comprising a central processing unit which is available to the operator who controls their operation. - Preferably, the
landing gangway 1 also comprises asecond transit platform 6, which is slidingly coupled to thefirst transit platform 2 so as to identify a first position, according to which thefirst platform 2 is unusable and is substantially housed in the encumbrance of thesecond platform 6, and a second position, according to which thefirst platform 2 protrudes along the longitudinal axis Z from thesecond platform 6, becoming an extension of thesecond platform 6, which in turn identifies anupper surface 7 that can be walked by people. - In practice, therefore, the
first transit platform 2 is telescopically coupled to thesecond transit platform 6; this occurs thanks to guide means, which are not shown for simplicity and which are interposed between thefirst platform 2 and thesecond platform 6. - The actuating means 5 are operatively connected to the
first transit platform 2 so as to place it between the above mentioned first and second positions, as well as between the rest position and the operating position. In other embodiments of the landing gangway of the invention, which are not shown in the attached drawings, the first and the second platforms may be coplanar with one another in said second position, thanks to elevation/lowering means: in this way, the landing gangway of the invention prevents the risks of accidental stumbling and subsequent fall for people, thus making it more secure than the known landing gangways for boats. - Preferably, the
landing gangway 1 of the present invention includes a gripping and/or supportrear rod 32, that is coupled to one of theside edges second transit platform 6 and that is operatively connected to the gripping and/or supportfront rod 4 by means of flexible cables, not shown for the sake of simplicity, which are able to assume the same operating position of thefront rod 4 in the rest and operating positions. - The
front rod 4 is coupled to thefirst transit platform 2 through rotation means, generally indicated with 8, cooperating with the actuating means 5 for selectively placing thefront rod 4 between the rest position and the operating position. - The rotation means 8 are placed at the
access end 2c of thefirst transit platform 2, as shown in the enlarged detail offigure 2a . - According to the preferred embodiment of the invention, herein claimed, the rotating
means 8 comprise ashaft 9 which identifies a linear axis of rotation X perpendicular to the longitudinal axis Z of thefirst transit platform 2. - The
shaft 9 is also coupled to thelower end 4a of thefront rod 4 through fixing means, generally indicated with 10 and comprising, for example, anassembly ring nut 33 and a cap with anut screw 34. - More in detail, the
shaft 9 is essentially contained between theside edges first transit platform 2 from which protrudes only for afirst end pin 11 inserted into a through hole, not shown, which is provided in one ofsaid side edges first transit platform 2 and which is partially contained in acoupling sleeve 12 associated with thelower end 4a of thefront rod 4. - In particular, the
shaft 9 has a partially squared or grooved outer surface 9a in order to increase its coupling capability with the other components which indirectly connect it to thesecond transit platform 6, as will be better clarified in the following. - The
coupling sleeve 12 is generally welded to a folded end portion 13 of thefront rod 4. - With regard to the fixing means 10, the enlarged detail of
figure 3a shows that theassembly ring nut 33 is externally coupled to thecoupling sleeve 12. - Preferably, the
landing gangway 1 includes, in correspondence of the rotation means 6, elastic means, which are generally indicated with 14 and are associated with said rotation means 6: theelastic means 14, shown in the attachedfigure 3a , have the function to counteract the action of theactuating means 5, thus resulting progressively compressed up to a load condition, when thefront rod 4 passes from the rest position to the operating position, and progressively released up to a release condition, when thefront rod 4 passes from the operating position to the rest position. - The elastic return means 14 comprise for example a
torsion spring 15 which is disposed around theshaft 9. - With reference to the actuation means 5, they are of the automatic type and include a
linear actuator 16, shown in the attachedfigure 2 , which: - is actuated along said longitudinal axis Z;
- is placed below the
first transit platform 2; - is coupled with the rotation means 6 by means of a lever system, generally indicated with 17 and shown in the attached
figures 3, 3a and 4 , so as to place thefront rod 4, respectively, between the rest position and the operating position. - In particular, the
linear actuator 16, for example of the hydraulic type, comprises: - a cylindrical chamber, coupled to the lower wall 6c of the
second transit platform 6 by means of known supporting means, generally indicated with 18; - a cylindrical stem which cooperates with the
lever system 17 and which slides along the longitudinal axis Z of thefirst transit platform 2 so as to be contained in the cylindrical sleeve in the rest position of thefront rod 4 and so as to axially protrude partially from the cylindrical sleeve in the operating position of thefront rod 4. - It is emphasized that the cylindrical chamber of the
linear actuator 16 is coupled to the lower wall 6c of thesecond transit platform 6 only for the specific structure of thelanding gangway 1 as described herein. - It is also clear that in other embodiments of the invention, which are not shown in the attached drawings, the cylindrical chamber of the linear actuator can be coupled to the lower wall of the first transit platform or to the inner wall of a housing of the boat or of a generic access infrastructure where the landing gangway claimed herein is fixed.
-
Figures 3a and 4 show that, according to a preferred embodiment of the invention, thelever system 17 comprises: - a
shaped lever arm 19 which is integral with theshaft 9 of the rotation means 8; - a connecting
hinge 20 to which the shapedlever arm 19 is pivoted; - a
rigid bar 21, which is arranged below thefirst transit platform 2 and which defines a linear axis Z', along which saidbar 21 slides by the actuation means 5; the axis Z' is parallel to the longitudinal axis Z of thefirst transit platform 2, while thebar 21 is provided with afirst end 21a coupled to the connectinghinge 20. - More specifically, the shaped
lever arm 19 has alinear wall 22 adapted to be oriented towards the outside of thefirst transit platform 2 when thefront rod 4 is in the operating position: this structure arrangement avoids the mechanical interference of the shapedlever arm 19 with the connectinghinge 20 in said operating position of thefront rod 4. - The shaped
lever arm 19 also has a throughopening 23, preferably squared, in which asecond end pin 24 of theshaft 9 is inserted. - The through
opening 23 is coaxial with the through hole formed in one of theside edges transit platform 2 and with theconnection sleeve 12 which is provided at the lower end of thefront rod 4. - In the rest position of the
front rod 4, shown infigure 2b , the shapedlever arm 19 is partially housed in the connectinghinge 20, while in the operating position of thefront rod 4, shown infigures 2, 2a and3 , the shapedlever arm 19 is pivoted to and protrudes from the connectinghinge 20, thus identifying a direction which is mainly oblique. -
Figure 2 also shows that therigid bar 21 slides along a peripherallinear seat 25, which communicates with the outside through anoutlet mouth 26 formed in thesecond transit platform 6, in which therigid bar 21 is fully housed when thefront rod 4 is in a rest position. - The
rigid bar 21 is also provided with amechanical stop 27 near asecond end 21b; themechanical stop 27 is applied to theouter wall 21c of therigid bar 21 and is coupled with abutment means, generally indicated with 28, which are placed in correspondence with theoutlet mouth 26 of the peripherallinear seat 25 so as to stop the sliding of therigid bar 21 along the linear axis Z'. - As shown in
figure 3b , the abutment means 28 comprise abush 29, provided with ahead 30 fixed to thefront edge 6d of thesecond transit platform 6 so as to surround theoutlet mouth 26. - The
sleeve 29 is also provided with ashank 31, which is inserted in the peripherallinear seat 25 and which is coupled with thestop element 27 so as to stop the axial movement of therigid bar 21, as shown in the enlarged detail offigure 2a . - The other attached figures from 5 to 8 show another possible embodiment of the invention, in which the landing gangway, which is generally indicated with 50, differs from the
gangway 1 previously described mainly in the structure of the lever system, generally indicated with 58, by means of which thelinear actuator 57 cooperates with the rotation means, generally indicated with 56, so as to place thefront rod 52 respectively between the rest position and the operating position. - In the present embodiment the
lever system 58 includes: - a
shaped lever body 59 which is integral with theshaft 63 of the rotation means 56; - a
pawl 60 which protrudes downward from the front end 57a of thelinear actuator 57 and which, under the thrust of the latter, is coupled or mechanically interferes with the shapedlever body 59 up to have thefront rod 52 in the above mentioned operating position. - Preferably, the shaped
lever body 59 has a U-shaped structure, in side view, and a pair of openedrecesses 61 facing each other and communicating with the outside. - The
pawl 60 is welded to atransverse bridge 62 which separates it from thelinear actuator 57 to which thetransverse bridge 62 is, in turn, welded. Another feature that distinguishes the landing gangway 50 from thelanding gangway 1 refers to the structure of the rotation means 56, which comprise the above mentionedshaft 63 protruding from both opposedside edges first transit platform 51, being provided with end pins 64, 65 inserted in respective throughholes side edges first transit platform 51. - Unlike the
landing gangway 1, thelanding gangway 50 of the invention also comprises a plurality ofrear rods 54, which are uniformly distributed on one of theside edges second transit platform 53 to which thefirst transit platform 51 is preferably coupled in a telescopic way. - The
landing gangway 1 according to the invention is normally in the functional position shown in the enlarged detail offigure 2b , in which thefront rod 4 and therear rod 31 have a rest position and thefirst transit platform 2 is housed in the encumbrance of thesecond transit platform 6 when it has the above mentioned first position. - If required, the
landing gangway 1 is moved for example towards the dock or the pier so that people are able to board the boat or any other walkable structure. - The operator, through the control means, actuates the actuation means 5 and particularly the
linear actuator 16, whose stem exits from the cylindrical chamber and progressively pushes thefirst transit platform 2 along the longitudinal axis Z so as to place it outside thesecond transit platform 6. - The thrust which is given to the
first transit platform 2 through the stem of thelinear actuator 16 causes the simultaneous traction along the linear axis Z', parallel to the longitudinal axis Z, of therigid bar 21 of thelever system 17, by means of which thelinear actuator 16 is coupled with the rotation means 8 for selectively placing thefront rod 4 between the rest position and the operating position. - The
rigid bar 21 thus progressively protrudes from the peripherallinear seat 25 of thesecond transit platform 6 till when thestop element 27 counteracts thebush 29 of the abutment means 28 placed in correspondence of theoutlet mouth 26 of the peripherallinear seat 25. - At that point, the thrust that the stem of the
linear actuator 16 keeps on giving to thefirst transit platform 2 causes the movement of the shapedlever arm 19 which, by rotating in correspondence of thepivot 35, causes a clockwise rotation of theshaft 9 about the linear axis of rotation X and, in turn, a clockwise rotation of therod front 4 starting from the rest position. - The rotation of the shaped
lever arm 19, of theshaft 9 and of thefront rod 4 is stopped when the stem of thelinear actuator 16 reaches the end position, which is suitably provided so that thefront rod 4 reaches the operating position describing a maximum angle of rotation of 90°. - During the upward movement, through rotation, towards the operating position, the
front rod 4 pulls the rear gripping and/orsupport rod 32, through the flexible rope, not shown, which connects the tworods - In the operating position of the
front rod 4, the shapedlever arm 19 has the operating condition shown infigures 2a ,3 and 3a , while the return elastic means 14 are compressed to counteract the action of thelinear actuator 16 of the actuation means 5. - When the
front rod 4 reaches the operating position, thefirst transit platform 2 reaches the second position with respect to thesecond transit platform 6, according to which: - the
first transit platform 2 extends axially thesecond transit platform 6; - the
upper surface 3 of thefirst transit platform 2 is coplanar with theupper surface 7 of thesecond transit platform 6. - In order to bring back the front rod 4 (and, consequently, the rear rod 32) in the rest position and the
first transit platform 2 in the first position, starting respectively from the operating position and from the second position, the operator, by acting on the control means, gradually draws the stem of thelinear actuator 16 inside the cylindrical chamber, thus causing: - the gradual anticlockwise rotation, up to a maximum of 90°, about the linear axis of rotation X, of the
shaft 9 of the rotation means 8 and, in turn, of thefront rod 4; - the gradual rotation of the shaped
lever arm 19 up to a point where it reaches the operating condition offigure 2b ; - the sliding of the
first transit platform 2 along the longitudinal axis Z, in the opposite direction with respect to the previous one, up to the point where theplatform 2 is below thesecond transit platform 6; - the sliding of the
rigid bar 21 along the linear axis Z', in the opposite direction with respect to the previous one, up to the point where thebar 21 is almost totally contained in the peripherallinear seat 25 of thesecond transit platform 6. - Even during the passage of the
front rod 4 from the operating position to the rest position, the return elastic means 14 counteract the action of the actuating means 5, even if they are suitably released in order to dampen the counterclockwise rotation of thefront rod 4. - The operation of the
landing gangway 50 of the invention essentially corresponds to the operation of thelanding gangway 1, with the only difference constituted by the mechanical system of movement of thelever system 58. - At first, the axial movement of the
stem 68 of thelinear actuator 57 belonging to the actuation means 55 causes a first significant extension of thefirst transit platform 51 from thesecond transit platform 53, through sliding along the longitudinal axis Z. - Subsequently, the axial movement of the
stem 68 of thelinear actuator 57 causes the connection between the transverse bridge 62 (provided at the front end 57a) and a first openedrecess 61 of the shapedlever body 59 and the simultaneous contrasting between thepawl 60 and the inner wall 59a of the shapedlever body 59, and the counterclockwise rotation of theshaft 63 about the linear axis of rotation X for a maximum angle of about 90°. - This causes the rotation of the
front rod 4, which, starting from the rest position (figures 5-6a ), is placed in the operating position (figures 7-8a ). - The axial movement of the
stem 68 slightly goes on even after thefront rod 53 has reached the operating position, so that the front edge 68b of thestem 68 counteracts theinner surface 69a of theplate 69 of thefirst transit platform 51. - Consequently, the
stem 68 pushes thefirst transit platform 51 along the longitudinal axis Z causing the extension with respect to thesecond transit platform 6. - After reaching the end position of the
stem 68, thefirst transit platform 51 is in the above mentioned second position and is ready for use; advantageously, it is also coplanar to thesecond transit platform 53 thanks to the presence of elevation/lowering means, not shown, which are interposed between the twoplatforms - Moreover, suitable return elastic means, generally indicated with 70 and coupled with the
shaft 63 of said rotation means 56, counteract the action of the actuating means 55. - Obviously, the movements just described occur in the opposite direction (i.e. in a clockwise direction) when the
first transit platform 51 is brought back in the first position, thus returning in the encumbrance of thesecond transit platform 53 and thefront rod 53 is returned to the rest position according to which it lies along the longitudinal axis Z. - From the above description, it is therefore understood that the increased use safety landing gangway, particularly for boats, which is the object of the present invention, achieves the objects and realizes the advantages previously mentioned.
- Upon implementation, changes may be made to the increased use safety landing gangway of the invention, which provide, for example, the use of a gripping and/or support front rod for each side edges of the transit platform.
- In this case, a first side edge of the first transit platform has a through hole and the second side edge opposite the first side edge has a respective through hole coaxial with the previous one, while the rotation means may include a single shaft or two different shafts and the return elastic means may optionally include a torsion spring for each shaft.
- Furthermore, in other embodiments of the landing gangway of the invention, not shown, the gripping and/or support front rod may protrude upwardly from at least one of the side edges of the first transit platform, according to a direction which is not necessarily orthogonal, but which is oblique, with respect to the longitudinal axis of the first transit platform, so as to be available to the hand grip of people.
- Where the technical features mentioned in the subsequent claims are followed by reference numbers or signs, said reference signs have been introduced with the sole purpose of increasing the intelligibility of the claims themselves and, consequently, they have no limiting effect on the interpretation of each element, which is thus identified only by way of example by said reference signs.
