[0001] The present invention generally relates to a retractable balcony for boats, such
as for example yachts, super-yachts and other crafts or boats in general.
[0002] More in particular, in use, the decking and/or ptotection balcony of the present
invention is arranged projecting from the boat side, preferably in correspondence
with the shipowner housing chamber.
[0003] As known, the most modern, sophisticated and generally luxurious pleasure crafts,
such as yachts, super-yachts, catamarans or the like, include a service side door
that normally, during shipping, closes a compartment obtained in the boat side, in
correspondence with the internal environments more comfortable and prestigious of
the boats.
[0004] The service side door includes at least one shaped door provided with an outer surface,
which is usually made of the same material of the boat side or the boat hull, for
example fiberglass, and which, when the side door closes the compartment, makes continuous
and uniform the boat side, thus being coplanar.
[0005] This is due primarily to the fact that the outer surface of the shaped door is convex
according to a radius of curvature that follows faithfully the radius of curvature
of the boat side parts which are adjacent to the compartment that houses the side
door.
[0006] Usually, the service side door also comprises a second shaped door, placed above
the first shaped door and cooperating with said first shaped door to close the compartment.
[0007] In particular, the second shaped door comprises a perimetral loading chassis supporting
a panel made of transparent material, for example glass, to allow the view of the
external environment to people standing within the premises of the boat.
[0008] If necessary, especially when the boats are moored at the port or at sea, the shaped
doors of the service side door are moved to open partially or completely the compartment
and allow the airing of said internal premises of the boat.
[0009] Where the opening of said shaped doors of the service side door is complete, each
of said doors protrudes from the boat side along a plane which is substantially orthogonal
with or incident the curved plane of said boat side to define, respectively, a support
plane, provided with a suitable protective balustrade, and a covering plane.
[0010] In practice, on such occasions, the first shaped door of the service side door becomes
a real balcony, facing and overlooking the sea, walkable from the people to enjoy
the open air and sea views directly from the boat, while the second shaped door becomes
a kind of canopy, also projecting from the boat side and facing the sea, which protects
from the weathering, such as the beating sun, the people standing on the below balcony.
[0011] In order to have, when docking, a balcony of a certain room of a boat and in order
to have, generally and simultaneously, an overhanging roof above the balcony, allowing
people to have a direct access outside from said room overlooking the sea in full
comfort, the service side door includes actuating means, which are operatively connected
to the shaped doors. The actuating means, coupled to the boat side and particularly
contained in the compartment formed in said boat side, move the shaped doors between
at least one rest position, according to which the shaped doors are coplanar to the
boat side and close the compartment, and a working position, according to which the
shaped doors protrude laterally from the boat side along planes that are substantially
horizontal to become, respectively, a decking plane and a covering plane and to open
the compartment.
[0012] In a nutshell, when you want to transform the service side door in a balcony with
a roof, the drive means, suitably actuated by control means, such as for example a
hydraulic control unit, overturn outwards the shaped doors making them protruding
from the boat side.
[0013] On the contrary, when you want to return the shaped doors in a compartment closed
position, the drive means rotate in the opposite direction the shaped doors, by performing
on them an upward traction. The tilting and traction movement of the shaped doors
essentially consists in a rotation of said doors about an axis defined by mechanical
elements placed on the lower edge of the perimeter wall delimiting the compartment
formed on the boat and to which the service side door is associated.
[0014] A service side door having the above technical features is described, for example,
in
EP2305553A1, in the name of the same applicant of the present invention.
[0015] However, the side door described in said patent application has a remarkable manufacture
complexity, as well as complicated and expensive precision drives; said drawbacks,
in addition to affecting the hydraulic seal in the area of the boat side where the
side door is provided and the aesthetic effect of said side door, also involve, in
turn, a lengthening of the production times for making the side door, as well as high
production costs.
[0016] An alternative solution of a service side door is described in
EP2332820A1, which relates to a retractable balcony for boats, comprising a foldable platform
which is mounted on the boat side and a railing structure mounted on the platform;
the platform comprises a foldable box-like support and a foldable planar floor, which
are tiltable with respect to the boat side separately one from one another, while
the railing structure comprises a plurality of railing elements, hinged at the edge
of the box-like support and tiltable between a rest position, in which said railing
elements lie within the box-like support, and an unfolded position, in which said
railing elements rise vertically with respect to the box-like support.
[0017] When the platform passes from a closed position to an open position, initially the
box-like support is tilted and then the railing elements pass from the rest position
to the unfolded position and finally the planar floor is tilted.
[0018] Even in this case, however, further drawbacks are clear, such as the complexity of
movement, the overall dimensions of the structure and the high construction and operating
costs.
[0019] An object of the present invention is therefore to provide a retractable balcony
for boats, that allows to simplify, with respect to the prior art, the processing
to be performed for its installation on the boat side and which allows to reduce,
accordingly, the production and operating costs. Another object of the present invention
is to provide a retractable balcony for boats, which maintains the structural integrity
and the aesthetic effect of the boat side.
[0020] A further object of the invention is to provide a retractable balcony for boats,
which is applicable to any point of the boat side, thus allowing, in the design and
installation, to release the choices of the boat side area on which said balcony is
provided from the shaping of said boat side, thus increasing the versatility with
respect to the prior art.
[0021] These and other objects are achieved by means of a retractable balcony for boats
as claimed in the enclosed claim 1; other detailed technical features are shown in
the other dependent claims.
[0022] Advantageously, the retractable balcony for boats, which is the object of the present
invention, allows to simplify and minimize the processes to be performed at a shipyard
to make the compartment on the boat side where the balcony is obtained, thanks to
the use of specific means of rotation and translation, which act for moving a planar
structure from a resting position to a working position, so as to obtain, quickly
and easily, a balcony with a decking platform and with a plurality of extensible and
collapsible guardrails made of glasses or railings placed at a proper height.
[0023] Furthermore, the retractable balcony of the invention can be applied to any area
of the boat side, such as aft or bow, and not only in correspondence with the straight
portions of said boat side.
[0024] It is clear that this feature increases the flexibility of the design and installation,
which allows to meet new needs and feel of the customers and which is therefore extremely
appreciated and distinctive.
[0025] Further purposes and advantages of the invention will become clear from the following

- figures 12 and 13 show the retractable balcony in one of the embodiments according
to the present invention, respectively, in a vertical closed position and in an open
position projecting from the boat side.
[0026] With particular reference to the enclosed figures from 1 to 6, as well as to the
enclosed figures 12 and 13, which relate to a first embodiment of the retractable
balcony for boats, according to the present invention, in which the protection railings
of the balcony are made of glasses at a proper height, the overall structure is substantially
composed of a frame 10, preferably made of stainless steel and configured to be rotated
from a vertical position on the boat side M to a horizontal position, through the
hinge brackets 13, of a walking platform 11, preferably made of teak and attached
above the frame 10, and of a system of folding guardrails or protective railings 12,
which are preferably constituted by glasses.
[0027] In detail, the balcony is initially moved (tilted) from a vertical closed position,
in which it is substantially aligned with the boat side M (as shown in the enclosed
figure 12), to a horizontal open position, in which it is arranged protruding from
the boat side M (as shown in the enclosed figure 13), through a rotation, performed
by the hinge brackets 13, about the axis X which is parallel to the longitudinal extension
of the frame 10.
[0028] In the closed position, the overall structure of the balcony constitutes a part of
the same boat side M (fig. 12), which is coplanar with respect to the adjacent wall,
while, in the open position (fig. 13), due to the lowering of the structure, a compartment
is obtained in the boat side M, which allows access to the walking platform 11 of
the balcony from inside the boat, and vice-versa.
[0029] Two side uprights 14 are arranged on the opposite sides and within suitable seats
17 of the frame 10 and to said uprights 14 are fixed a front protection glass 15A
and two protection side glasses 15B; in particular, the side glasses 15B are folded
on the front glass 15A and are configured to be moved by means of special manual hinges
19.
[0030] The side uprights 14 are connected to the frame 10 by means of respective joints
and can rotate upwards making a complete angle ranging from 0°to 90°, starting from
the horizontal position of housing within the respective seats 17, thanks to the drive
of respective actuators, such as the hydraulic cylinders 16.
[0031] Furthermore, said side uprights 14 are also each provided with a further actuator,
such as a hydraulic cylinder 18, to cause the upward extension and said uprights 14
have also internally the manual hinges 19 for supporting and rotating the side glasses
15B; in particular, the front glass 15A is glued on the telescopic side uprights 14
and the telescopic portion of the side uprights 14 encloses the fixed part so as to
provide the bonding surface on the outside edge.
[0032] Therefore, from the horizontal position of figure 1, which is reached from the balcony
as a result of a rotation about the X axis starting from the vertical position on
the boat side M, a first rotation of the side uprights 14 and of the relative protective
glasses 15A, 15B occurs, due to the driving of the respective hydraulic cylinders
16 (fig. 2) up to a full rotation of 90° of said side uprights 14 with respect to
the horizontal plane of the frame 10 and the walking platform 11 (fig. 3).
[0033] At this point, a telescopic raising of the lateral uprights 14 is provided, thanks
to the drive of the respective hydraulic cylinders 18, with the consequent raising
of the front glass 15A and of the side glasses 15B, said side glasses 15B being still
folded on the front glass 15A (fig. 4-5). The balcony is then completed by means of
a manual rotation of the side glasses 15B, through the mobile hinges 19, and the fixing
of said side glasses 15B thanks to internal safety knobs 20, which prevent further
rotations; the mobile hinges 19 also have a mechanical stop 21 which prevents rotation
of the glasses 15A, 15B along the outside edge (fig. 6). With particular reference
to the enclosed figures from 7 to 11, which show a second embodiment of the retractable
balcony for boats according to the present invention and wherein the same numerical
references have been provided to show elements which are identical to the respective
elements shown in the figures from 1 to 6, the retractable balcony has substantially
the same structure of the first embodiment, with the only difference consisting in
that the protective folding railings 12 include a plurality of tubular pipes 25, which
make up a front railing 24A and two side railings 24B at a proper height.
[0034] The handling of the structure from a vertical position of the balcony on the boat
side M to a horizontal position (shown in the enclosed figure 7), as well as the handling
constituted by the rotation (fig. 8 and 9) and the telescopic extension of the lateral
uprights 14 (fig. 10) are all equal to those previously described in the case of the
retractable balcony with railings constituted by glasses, with the only difference
consisting in that said side uprights 14 have internal plate manuals hinges 26 for
supporting and rotating the side railings 24B.
[0035] In addition, the front railing 24A is welded on the telescopic side uprights 14 and
the telescopic part of said uprights 14 encloses the fixed part so as to provide the
sealing surface on the outside edge.
[0036] Finally, also the manual rotation of the side railings 24B takes place with the same
modalities previously described, by means of the plate hinges 26; similarly to what
already described, also the side railings 24B are fixed through internal safety knobs
20, which prevent a further rotation (fig. 11). It is clear from the given description
the features of the retractable balcony for boats, which is the object of the present
invention, as well as the related advantages are also clear.
[0037] Obviously, in the executive stage, modifications may be made to the retractable balcony
for boats, which is the object of the invention, consisting, for example, in providing
translation and/or rotation means which are different from those described earlier
and with reference to the accompanying drawings.
[0038] It is finally clear that many other variations may be made to the retractable balcony
for boats of the invention, without departing from the novelty principles inherent
in the inventive idea and according to the appended claims, as well as it is clear
that in the practical actuation of the invention the materials, shapes and dimensions
of the illustrated details can be any, according to requirements, and can be replaced
with other technically equivalent.
[0039] Where the technical features mentioned in the appended 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 and consequently they have no limiting
effect on the interpretation of each element identified by said reference signs.
