Description

[0001] DESCRIPTION

[0002] AID DEVICE CONFIGURED TO BE ATTACHED TO A BUOY

[0003] OBJECT OF THE INVENTION

[0004] This patent application relates to a rescue device designed to be attached to a buoy, with means for attaching it to the buoy and means for a swimmer to grab hold, according to claims 1 to 19, further incorporating significant innovations and advantages. It pertains to an invention that falls within the fields of maritime safety, swimmer and water sports safety, and buoyage equipment.

[0005] BACKGROUND OF THE INVENTION

[0006] Currently, it is established that marine buoyage is intended to adequately delimit bathing areas along the coast and other areas that do not require signals regulated by the maritime buoyage system. The technical characteristics of the buoyage are achieved, depending on its location, using buoys, and the party responsible for their installation is obligated to maintain, monitor, and control these buoys. However, this type of buoyage is not intended to assist people who are not on board vessels, such as a swimmer, bather, or water sports enthusiast who might be involved in an accident or become ill near the buoy.Furthermore, the design and size of these delimitation buoys make it very difficult for a person standing next to them to use them for minimal buoyancy assistance or to use them as momentary support until they are seen while they need and request help, either from other bathers or, if available, from the maritime rescue service of the beach or coastal area in question.

[0007] It is also observed that these marker buoys can worsen the emergency situation or indisposition that the person is suffering by posing an added danger due to the high risk of being hit by the inevitable movement caused by the sea at any given time.

[0008] It is also known from the prior art, as described in document KR1020200047993, to be a marine rescue system based on a smart buoy-type point for notifying the transmission of a rescue request signal to persons in distress. Specifically, it refers to a rescue system for determining environmental information in a hazardous location, as well as the location of persons in distress, activity information, and biological information using low-power long-range communication, receiving a GPS-based location signal, and similar technologies.The system comprises a life support device including a distress sensor, a signal transmission confirmation device, and a communication device; a buoy-type smart point capable of floating in the water, which includes a hazard determination device, a location measurement device, a storage device, a first communication device, and a second communication device; and a control server located on land or on a rescue vessel. This means that the person requiring assistance must already be wearing the life jacket containing the communication equipment.

[0009] It is also known from the prior art, as described in document KR1020220102792, that a maritime safety accident prevention system using a location-based buoy is available. It automatically detects a person, determines if they are in a dangerous situation, and receives a satellite signal transmitted from a GPS satellite to a GPS receiver unit. This accurately identifies the person's current location and transmits a rescue request signal, including location information, to a control point and a smart device, thus rescuing the person quickly and accurately. The system includes a sensor unit, a GPS receiver unit, a control unit, a lighting unit, and a smart device.The system has predefined areas of the sea or lake that are safe and those that are not, and it triggers an alarm when it detects that a person has left a safe zone, but it is not a system that can be activated by the person to indicate that they are in danger. The system assumes that the person is in danger based on their location.

[0010] Thus, in light of the above, the need arises to provide a grab and distress call device that can be adapted to any size and shape of buoy in a versatile manner to provide buoyancy assistance, as well as a distress call and geolocation device for anyone in an emergency situation. DESCRIPTION OF THE INVENTION

[0011] Currently, there are no specific safety regulations for existing buoys used by swimmers in the sea. This has prompted an analysis of the safety issues for these users, as well as the potential use of existing buoys in bathing and coastal areas, through a modular system.

[0012] The present invention seeks to solve the problems mentioned in the previous section, and to offer a gripping and alert-help solution, with both mechanical and electronic components, that is universal, expandable and energy autonomous, and can be installed on any buoy marking beaches, bathing areas and coasts.

[0013] It offers adaptability to any type, shape, and size of existing buoys along the coastline. Furthermore, it is modular, depending on the specific needs of each buoyage zone and the desired level of service.

[0014] Thus, it is possible to incorporate additional sensing devices that may be intended, for example, for monitoring sea conditions and water quality in marine scientific studies. These additional sensing systems communicate independently with each of their specific sensors and capture the data they provide for subsequent processing, storage, transmission, download, and visualization via an online application. The same data communication system used for the alert and rescue system for swimmers and athletes is used for the transmission of this specific data.

[0015] In short, the system that is the subject of the invention consists of a buoy coupling system, which includes a gripping and buoyancy aid element, and an electronic communication system, with the necessary technological equipment for calling and assistance.

[0016] More specifically, the rescue device designed to be attached to a buoy comprises means for attaching it to the buoy and a handhold for a swimmer, thus providing a means of support in an emergency, for example, due to an inability to swim to shore, either from lack of energy or from rough seas. Preferably, the attachment means are an adjustable mesh over the buoy, of variable size, allowing it to encircle the entire buoy and adapt to its size and shape.

[0017] Additionally, the mesh includes an opening with an adjustment tensioner, so that it can be narrowed and closed, until it is firmly fitted onto the surface of the buoy.

[0018] In a preferred embodiment of the invention, the adjustment tensioner comprises a locking mechanism for fixing the degree of slack in a fixed position. Optionally, the locking mechanism is located on the underside of the buoy, making it difficult for anyone to tamper with the mooring. Additionally, the locking mechanism may include a key as an extra security feature to prevent unauthorized manipulation or removal from the buoy.

[0019] According to another aspect of the invention, the mesh comprises a band with a plurality of gripping means distributed around its perimeter, in order to offer more points of support and buoyancy assistance to the bather in distress, without depending on the direction of approach to the buoy.

[0020] More specifically, the gripping means are in the form of handles, so that the bather can hold on comfortably and safely using their hands, even if the buoy is moving due to the sea or waves.

[0021] According to another aspect of the invention, the rescue device configured to be attached to a buoy comprises electronic alerting means, so that it is possible to alert the emergency services to come to the rescue of the bather in distress.

[0022] More specifically, the electronic alerting system includes IP68 protection, which enables greater resistance to the marine environment on the buoy.

[0023] On the other hand, the electronic alert system includes geolocation, or geographic positioning, capabilities to provide the exact geographic location, and is also compatible with the Galileo, GPS, and GLONASS GNSS global navigation satellite systems. According to a preferred embodiment of the invention, the electronic alert system includes communication capabilities with an emergency service, enabling the request for assistance and rescue from a professional service equipped for this purpose.

[0024] Optionally, the means of communication include an SOS button to activate the call for help.

[0025] It is worth mentioning that the media transmit an alert signal via mobile phone or satellite, with the current guarantees of these communication systems.

[0026] More specifically, the alert signal includes information on at least one identification data of the electronic means of alerting and / or type of alert and / or municipality and country and geolocation of the buoy, so as to facilitate the location and the specific situation of the bather in distress.

[0027] Additionally, the means of communication include a microphone and / or a loudspeaker, necessary to establish a conversation with the emergency reception service (112 service or equivalent depending on the country).

[0028] According to another aspect of the invention, the auxiliary device configured to be attached to a buoy comprises an electrical power supply battery necessary for its proper functioning.

[0029] Preferably, the aid device configured to be attached to a buoy comprises at least one photovoltaic cell, which allows the power supply battery to always be optimally charged and ready for use.

[0030] Additionally, it includes flashing lights to indicate an emergency. These lights offer 360° visibility and are high-intensity, using energy-efficient LEDs with flashing capability, which will activate specifically when an emergency call is made. The flashing SOS signal is emitted through flashes of varying durations, in accordance with international SOS signal emission guidelines. Furthermore, it includes at least one sensor configured to measure a variable from the group of physicochemical and / or biological anomalies, such as turbidity or pH of the water, thus aiding in water quality monitoring for marine scientific studies.

[0031] Furthermore, it comprises at least one sensor configured to measure a variable from the group of atmospheric pressure, wind, temperature, humidity, solar radiation, CO2, nutrients, chlorophyll, plankton, wave speed and direction, detection of marine species such as jellyfish and fish, which allows the monitoring of sea conditions in marine scientific studies.

[0032] The accompanying drawings show, by way of non-limiting example, an auxiliary device configured to be attached to a buoy, constructed according to the invention. Other features and advantages of said auxiliary device configured to be attached to a buoy, the subject of the present invention, will become apparent from the description of a preferred, but not exclusive, embodiment, which is illustrated by way of non-limiting example in the accompanying drawings.
