Description
OBJECT OF THE INVENTION
[0001] The invention relates to a propulsion system for assisting
the paddling in the practice of surfing comprising a propelling
device intended to be mounted on a surfboard; with the
particularity that said propelling device is controlled
electronically and wirelessly by a control device suitable for
being placed on an arm of the user and which translates the user's
strength and speed of paddling into a proportional control signal
of the propelling device; so that the propelling device supplies a
drive proportional to the paddling intensity of the user.
FIELD OF APPLICATION OF THE INVENTION
[0002] This invention is applicable in the practice of surfing.
STATE OF THE ART
[0003] In the last decade, both the practice of the surf and the
lifestyle, the way of dressing and the tourism associated with it,
has increased exponentially, becoming a popular sport of easy
initiation in multiple sites of the planet.
[0004] This new situation causes that the public that accedes to
begin in the surf is very varied in terms of age and physical
condition.
[0005] Surfing is a very demanding sport physically and
technically, as well as being dangerous on multiple occasions due
to various factors, such as the complexity of the tides, the
impacts of the waves and the physical wear to which the
practitioners are exposed, which are not always in the best
physical conditions.
[0006] The forecasts are that this sector will continue to grow in
number of users and new companies are appearing to offer the
service of training and rental of material.
[0007] The materials used are being modernized in some aspects,
such as the incorporation of technical fabrics into garments that
offer greater thermal protection; or the incorporation in the
surfboard of impulse means controlled at will by the user and that
allow to move without making any effort.
[0008] Obviously, the incorporation of these means of drive in the
surfboard, eliminates the need to make a physical effort to
practice surfing and therefore one of the important aspects of
surfing is precisely the practice of a sport with an important
physical requirement, especially during the paddling operation to
overcome and catch the wave, or "take off".
[0009] Another point to keep in mind is that the practice of
surfing is stationary, which means that users are not regularly
practicing this sport of high physical demand, so at the time of
practice, they are not always in optimum physical condition to be
able to practice surfing properly.
[0010] Taking into account the physical demand that requires
practicing and enjoying surfing, the technical problem that arises
is the development of a paddle assistance system that provides the
user with safety and assistance in the displacement produced by
paddling proportional to the effort of paddling by the user, for
example to leave a complicated area, but with requiring its
operation physical effort of the user.
[0011] It is worth mentioning that the applicant of the present
invention is unaware of the existence of previous background that
present technical, structural and constitutive characteristics like
those presented by the paddle assistance system in the surfing
practice of the present invention.
DESCRIPTION OF THE INVENTION
[0012] In order to face these problems, a propulsion system has
been designed for surfing assistance in the practice of surfing,
being of the type that incorporates a propelling device associated
with the surfboard, it has the particularity that said propelling
device is controlled electronically and wirelessly by a control
device suitable for being placed on a user's arm which translates
the force and speed effected by the user when paddling on a
proportional control signal of the propelling device.
[0013] The control device has a configuration such as a bracelet or
armband, suitable for attachment to a wrist or arm of the user and
comprises: --a microprocessor, --a power supply battery, --sensors
that provide the microprocessor with data suitable for identifying
the action of paddling, calculating the speed and intensity of
paddling and generating a control signal of the propelling device
proportional to the paddling intensity of the user and; --wireless
communication means, suitable for transmitting the control signal
to the propellant device incorporated in the surfboard.
[0014] It should be mentioned that the sensors integrated in the
control device comprise at least one of those indicated below: a
pressure sensor, an inclinometer, a gyroscope, a geomagnetic sensor
or an accelerometer. The possibility of incorporating in the
control device sensors capable of taking from the user the values
of vital signs that vary during the performance of an effort or in
a stress situation, such as blood pressure or heart rate, has also
been envisaged.
[0015] The propellant device, hydro jet type, comprises: a
propeller or propeller driven by the corresponding motor, power
batteries and control unit provided with a wireless receiver for
capturing the signals coming from the control device; and wherein
said control unit is responsible for varying the power of
propulsion according to the signals received from the control
device, and consequently proportional to the user's padding
intensity.
[0016] In an embodiment of the invention, the propeller device is
integrated in a detachable keel provided with standard fastening
means, which allows its incorporation into any current surfboard of
the market and of any manufacturer.
[0017] This feature allows the system of the invention, composed of
the propelling device and the control device, not to be integrated
or permanently associated with a certain surfboard, and which can
be disassembled and transported in a small space, without the
surfboard, for later assembly in any other surfboard.
[0018] This propulsion system gives the user more power in the
paddling, necessary to match its speed with the wave and to start
then the phase of catching the wave or "take off" and surfing.
[0019] If the user is not paddling the device does not provide
propulsion, since the propulsion goes direct, provided and only
associated with the paddling action of the user, if the user does
not row the system does not propel.
[0020] This feature provides a very real feeling to the user since
it will never be propelled only artificially, unlike what happens
with existing products in the market.
[0021] With this drive system the technique is not altered, nor the
natural or authentic practice of surfing since the knowledge,
experience to have a good position and control the timing depends
on the knowledge of the surfer, as well as the technique of tracing
and catch the wave or "take off" and the next maneuvers of turns on
the wave.
[0022] Actually, this drive system only gives you a plus power
proportional to the force applied in the paddle just at the time of
rowing a selected wave before trying to catch it.
