Description
The present invention relates to a safety device for flotation and
uprighting (straightening) of sailing boats.
Up to the present day, safety devices and safety systems developed for
sailing boats have been based, in general, on elements external to the
boat itself. In particular, these are inflatable boats or dinghies or other
rigid hulls, which, in the event of danger, enable safe transfer thereon of
the occupants of the main hull. Solutions of this sort, albeit very effective
in terms of safety of the occupants, do not, instead, solve the problem of
safeguarding the boat in so far as they are not designed for said purpose.
A purpose of the present invention is to provide a safety device for
flotation and uprighting of sailing boats that will ensure protection of the
boat as a whole by means of structural elements forming part of the boat
itself.
Another purpose of the present invention is to provide a safety device for
flotation and uprighting of sailing boats that will furnish a system capable
of detecting the situation of danger of overturning and automatically
proceed to guaranteeing flotation of the boat and so favour its
uprighting.
Yet another purpose of the present invention is to provide a safety device
for flotation and uprighting of sailing boats that will be particularly simple
and functional, with contained costs.
The above purposes according to the present invention are achieved by
providing a safety device for flotation and uprighting of sailing boats, as
specified in Claim 1.
Further characteristics are described in the dependent claims.
The characteristics and advantages of a safety device for flotation and
uprighting of sailing boats according to the present invention will emerge
clearly from the following description, which is provided by way of nonlimiting
example, with reference to the annexed schematic figures, in
which:
- Figure 1 is a schematic view of a sailing boat provided with a safety device for flotation and uprighting of sailing boats;
- Figures 2a and 2b illustrate schematically the entry into action of the safety device forming the subject of the present invention following upon the dangerous inclination of a sailing boat, a single-hull and a multi-hull one, respectively;
- Figure 3 is a schematic illustration of an embodiment of a mechanical sensor belonging to the safety device that forms the subject of the present invention;
- Figure 4 is a block diagram of the operation of a digital embodiment of the sensor of the safety device forming the subject of the present invention; and
- Figure 5 is a cross-sectional view of a multilayered sail provided with inflatable elements belonging to the safety device of the invention.
With reference to the figures, a safety device is illustrated for flotation and
uprighting of sailing boats, whether single-hull or multi-hull ones, as a
whole designated by 10 and comprising: a sensor device 12 for detecting
the inclination of a hull 11 with respect to a plane of flotation on the
water (water level); a means for supplying gas 13, consisting, for
example, of a compressor or a cylinder; and one or more inflatable
elements 14.
The means for supplying gas 13 is connected to the inflatable elements
14 via a pneumatic circuit 15 comprising one or more tubes, for example
made of rubber or of any other material suitable for the purpose of
transferring the gas supplied by the compressor or by the cylinder 13 into
the inflatable elements 14.
Figure 1 illustrates by way of example four inflatable elements 14 (shown
outlined) connected in parallel to the means for supplying gas 13. Said
inflatable elements 14, which can be of any number and could also be
connected in series, are preferably fixedly constrained to the equipment
of the boat, for example at the top of the mast 16, or else at various
heights of the mast 16, or at the helm either at the bow 18 or at the stern,
or else on the hull 11 preferably in a position that is high above the
horizon represented by the water level.
In a first embodiment illustrated in Figure 1, the inflatable elements
consist, for example, of balloons contained, when deflated, in a housing
19, from which they exit when they are inflated.
Alternatively, the inflatable elements 14 could also be directly housed in
the mast.
The sensor device 12 has the function either of detecting the situation of
danger deriving from an excessive inclination of the hull or else of
indicating contact with the water, for example of the sail 20 itself or of
any other element of the boat that indicates, on the basis of predetermined
parameters, a situation of danger of capsizing or overturning.
The sensor device 12 may, for example, be of a mechanical type 12a or
of a digital type 12b, or of any other appropriate type for the purpose
indicated above such as, again by way of example, devices for
measuring pressure, humidity or other parameters.
An example of mechanical sensor 12a, illustrated in Figure 3, may be a
so-called "level sensor", in which a liquid or a ball 21 is free to rotate
within a bulb 22 and indicates the lateral inclination of the hull 11 with
respect to the horizon represented by the level of the water surface.
Once a certain inclination is exceeded with respect to the plane of
flotation on the water or of the horizon, as illustrated by way of example
in Figures 2a and 2b, the sensor 12a indicates the situation to the
compressor or to the cylinder for supplying the gas 13, which, since it is
activated automatically, will inflate the elements 14 through the
connection tubes 15.
The digital sensor 12b, instead, of which a possible scheme of operation is
illustrated in Figure 4, can receive information from a series of sensor
elements 23 located in various parts of the boat, to transfer the
information regarding the inclination of the hull 11 in real time to a control
unit 24, for example a computer, which, through the continuous
processing of the data, compared to pre-set numeric parameters, will
establish automatically the moment in which the situation of danger is to
be indicated by sending the electronic impulse for activation of the
means for supplying gas 13.
The means for supplying gas 13, i.e., the compressor or the cylinder for
supplying gas, may exploit a system similar to what is already in use in
automobile air-bags, which are able to supply large amounts of gas in
just a few instants, guaranteeing a fast and hence effective, in terms of
safety, inflation of the elements 14. The supplying means must moreover
keep at least one inflatable element 14 inflated.
The safety device 10 further comprises means for deflating the elements
14 after their entry into action so that it is possible to resume navigation in
conditions of safety after the purpose of preventing overturning of the
boat has been achieved.
Figure 5 illustrates a further embodiment of an inflatable element 14
consisting of an inflatable multilayered sail 20'. The third dimension of the
sail 20', i.e., its capacity to inflate, is obtained by superimposing two faces
or layers 25 and joining their perimeters using any one of the known
techniques, for example by sewing, gluing, hot-sealing or some other
technique. It will then be possible to insert between the two faces 25 of
the sail 20' one or more bladders (i.e. gas chambers) 26, each equipped
with an inflation valve 27, and then proceed to their inflation at the
moment when the cylinder or the compressor 13 receives the impulse
from the sensor device 12. In the case where the two layers 25 of the
inflatable sail 20' are able by themselves to withhold the air within them,
i.e., they are impermeable to the gas, it is possible to proceed directly to
the inflation of the bladder formed by the two layers 25 of the sail, if
necessary, divided into a number of compartments, each equipped with
an inflation valve.
The safety device for flotation and uprighting of sailing boats forming the
subject of the present invention has the advantage of combining the
action of uprighting of the hull with flotation thereof.
The safety device forming the subject of the invention may moreover
advantageously be activated automatically when a given situation of
pre-set inclination is reached.
The safety device thus conceived may undergo numerous modifications
and variations, all falling within the scope of the present invention.
Furthermore, any of the items may be replaced by technically equivalent
elements. In practice, the materials used, as well as the dimensions, may
be any whatsoever according to the technical requirements.
