FR2768250A1 - Personal alarm for warning of risk of drowning for swimmers - Google Patents

Abstract

The device is activated automatically by immersion in water to sound remote alarm. The safety device to be worn by bathers may consist of a bracelet (3) with a rectangular casing attached, or a wrist strap in two parts (12,21) to which a cylindrical unit is attached. The unit comprises a casing (13) housing a battery (15) and a base plate (24) with an internal waterproof sealed section. When the unit is immersed in water, a circuit is completed in order to activate a transistor circuit. This includes an amplifier and transmitter connected to an aerial to generate a remote warning sound.

Description

DEVICE FOR THE SECURITY OF INDIVIDUALS IN FRONT
OF A RISK OF DROWNING
The present invention relates to the safety of people and more particularly, that
young children.

The security of people is generally guaranteed by the police forces responsible
to uphold the law, protect people and their property
There is another area in which parents or caregivers
communities must themselves assume the security of the beings for whom they are responsible.

 This area concerns that of accident by immersion.

 The present invention relates to the risks of drowning accident.

The present invention has the effect of avoiding accidents relating to the immersion of a
young person or older when in an indoor area
of which there is risk of asphyxiation by drowning.

This risk of suffocation is more and more common in modern life because it
there are many swimming pools or water points authorized for swimming.

Bathing is for many of us a very simple joy of growing
widespread, therefore commonly practiced.

This kind of hobby poses less problem from adolescence except if in
a group, exist one or more members likely to drown from
the place where they don't have feet.

In return, leisure activities, increasingly motivated by communities
have the effect of encouraging groups of young children to swim, to
inside water points that municipalities have set up for this purpose.

The invention relates more precisely to young children and draws their attention to the problem of drowning by immersion.

This immersion is very dangerous in the swimming pools inside the properties, because the person responsible for ensuring the safety of the child cannot intervene to help him within the healthy time limits if the child has accidentally fallen into the swimming pool.

 However, at any moment, a child can fool the vigilance of his parents or his close relations when in the environment, is a swimming pool.

In the environment of public swimming pools, where lifeguards ensure the safety of individuals, many people at risk deceive their vigilance.

This difficulty increases when a person is responsible for a group authorized to bathe on the bank of a river, in an artificial water point or by the sea.

In this configuration of swimming, the water level increases, as does the risk of accident.

This is all the more serious at the seaside because the hydraulic level increases with the waves.

In the case located on the bank of a river, the problem is posed by the fragility of the banks and the vagaries of the current.

Until this day, failing to limit the joy of children by depriving them even in favorable weather of the great joy of wading in the water, the group leader would take insane risks.

Concretely, it is impossible for the supervisor to have an eye for everything, especially when you know that it takes less than three minutes of immersion to affect an individual's life.

In the immersion bathing sector, the present invention aims to replace human service, both for a close member of the family and for an authorized manager.

The present invention uses components widely used in the industry, in particular, over-the-air communication.

This over-the-air communication will retain the instantaneous speed of the transmission without distance limits.

The present invention uses water as an effective contact element.

The present invention comprises a transmitter united to the person at risk and a receiver available to the manager.

The present invention takes the form at the transmitter station, of a small waterproof watch with a preferably elastic strap and housed on the upper part of the individual such as a frontal entourage or the shape of a fixed collar around the neck.

This strategic position on the individual is applied because the person can be submerged safely up to neck height.

The invention takes into account the fact that the individual even at a young age is endowed with a survival reflex so much so that if the water level exceeds the top of his chest, he will attempt a retreat to save his life .

The invention takes into account the fact that natural elements risk being right for the person in a position of danger.

This is where the device of the invention comes in.

The water will instantly bring the negative and positive low-voltage poles of the transmitter mechanism into contact, which will instantly alert the manager.

His intervention will be carried out in record time as he was instantly warned of a risk incurred.

The application of the invention contemplates the fact that the person concerned was immersed for an instant by a fall or due to a whim or even after a game.

As soon as the device is out of immersion, the transmitter stops and the person in charge has simply recorded the incident, which can still be useful for the following in order to watch over the person concerned to know if he has not enter a danger zone.

The present invention takes into account the fact that the manager is inside a property, where there is a swimming pool or else as part of a more collective responsibility, the receiver which he has is reliably connected to all the transmitters with incidence by immersion, the number of which is limited its responsibility.

Concretely, the radio wave used by the invention saves precious time in the event of danger to any person responsible, and allows him to be less worried and in the event of accidental immersion, gives him a salutary response time.

In one of the applications of the invention, by way of non-limiting example, to Fla. (1):
(1) is standard antenna. (2) is the fixing of the antenna. (3) is a tab intended to hold the device. (4) is the sound amplifier. (5) is the holding circle of the sound amplifier. (6) is the super light housing. (7) is the battery opening flap (8) and (9). (23), (11) and (10) are the standard transistors widespread in the industry and compatible with an amplifier and a transformer of sounds widespread in the trade.

In FIG. (2): (12) and (21) are the ends of a bracelet, preferably elastic, with the standard automatic closure. (15) is a standard battery, it is connected by the device (13) to a plate (24). (16) and (17) form a sealed and insulating curved bowl which in no way allows electrical current to be transmitted to the plate (19), which is in relation to the standard model sound amplifier transistor (20). (18) is the whole of the waterproof extra light housing made of standard material.

Claims (2)

 RE VENDICA TIONS 1. Device intended for the safety of individuals facing the risk of drowning, characterized in that it comprises one or more transmitters (18) emitting waves to the housing (6) as soon as the curved plates ( 16) and (17) precisely made of insulated material are immersed even by a small amount of water which brings the plates (19) and (24) into contact thus causing a sound emitter thanks to the battery (15) and (20) , these waves being transmitted instantaneously to the antenna (1) synchronized with the transistors (10) (11) and (23) intended for the sound amplifier (22). 2. Device according to claim 1, characterized in that the housing (18) is not limited in number at the level of the transmitting elements and also not restrictive in the distance.
