ES2272195A1 - Safety device for divers, has control circuit that operates inflator to expand floater when measured time of timer has exceeded predetermined time or when depth gauge has measured dangerous water depth - Google Patents

Abstract

The device includes a timer and a depth gauge connected to a control circuit. The control circuit operates an inflator to expand a floater using gas pressure when the measured time of the timer has exceeded a predetermined time or when the depth gauge has measured dangerous water depth. The device is set integral to the diving suit of the diver, preferably on the abdominal or cervical section of the diver. The device also includes a signaling unit for indicating the location of the diver.

Description

Safety device for divers.

Object of the invention

The present invention relates to a device that has been conceived as a security element for divers, in particular for diving "to lung".

The object of the invention is to provide a device that activates automatically, after exceeding a preset dive time and / or a depth threshold considered as dangerous for the integrity of the diver, of so that such activation automatically causes the diver emerges to the surface.

It is also the object of the invention that the device can be activated manually by own diver

Background of the invention

The practice of diving is an increasingly sport usual in this society, and one of its modalities, diving "to lung", that is to say without the contest of air bottles tablet that facilitate the diver's breathing underwater It is increasingly widespread.

Said modality, since there are no elements available auxiliary to facilitate breathing underwater, can be extremely dangerous if time exceeds more than that the diver himself is able to bear containing the breathing, as well as due to the high pressures that occur on the body of the same once passed a certain level of depth.

In order to allow controlling these parameters there are devices in the market capable of measuring depth as well as the time the diver remains submerged.

The problem presented by this type of devices is that they only act as indicator means, of so that if the diver ignores them, either by carelessness or fainting, such devices do not allow for themselves act on the diver raising it towards the surface.

Description of the invention

The safety device for divers solves the problem fully satisfactorily previously exposed, so that after exceeding some time preset diving and / or a depth threshold considered as dangerous, it automatically causes the rise of diver to the surface by floating his body.

To do this, and more specifically, the device that is recommended is made up of a depth gauge and a clock or immersion time measurement system, associated with a control circuit that can incorporate maximum preset values of immersion time and diving depth, or so that these parameters can be selected by the diver himself depending on the preparation and experience of the
same.

In this way, once the dimension is exceeded maximum diving depth and / or the set time limit, the said control circuit acts on a electro-valve or similar opening element of a small gas tank under pressure, preferably air, causing automatically the inflation of a float associated to it, of so that the inflation of the aforementioned float inevitably causes the diver's elevation to the surface.

Obviously, the different elements Electrical / electronic device will be conveniently sealed in order to allow its correct operation under Water.

The device will have reduced dimensions that allow its easy integration into the suit of Diver's neoprene, being able to implant indistinctly over the cervical area, to ensure buoyancy of the head of the diver, or on the front abdominal area.

According to another of the characteristics of the invention, it is provided that the device incorporates a control of manual activation, so that the diver can activate so conscious for himself, even though he has not exceeded the time of immersion or depth preset, in case consider necessary.

Finally, it should be noted that the aforementioned float you can incorporate any type of signaling, in order to facilitate the location of the diver.

In this way a device of extremely effective security, which counteracts the tendency to sink from divers due to the usual ballasts incorporate to facilitate its descent, causing its elevation until the surface automatically, minimizing very considerable risks associated with the practice of this type of sport.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of this description, a single set of drawings where Illustrative and not limiting, it has been represented as schematically form a safety device for divers performed in accordance with the object of the present invention.

Preferred Embodiment of the Invention

In view of the review figure you can be observed as the safety device for divers of the invention participates a housing (1), of reduced dimensions, conveniently sealed, in which set a depth gauge (2) and a clock (3), associated with a control circuit (4) whose programming parameters, corresponding to the maximum depth level for the diver as well as the maximum immersion time can be previously preset, or be selected by the diver himself through a keyboard (5) or any data entry interface equivalent.

In this way, when the depth gauge and / or the clock exceeds the maximum safety parameters set, the control circuit (4) is responsible for acting on a solenoid valve (6), causing its opening.

One end of said solenoid valve (6) is associated with a small cylinder or gas tank (7) at pressure, preferably compressed air, while its other end is tied to an inflatable bag or float (8) that remains perfectly folded until the moment of opening said valve (6), in which it increases considerably from volume when deployed and swollen producing the afloat of the diver

As mentioned earlier, the device will present as compact a configuration as possible, being able to be part of a diving suit, or constitute a independent element, integrable on it, specifically over the cervical area or in the front abdominal area.

A reusable or replaceable character of the gas cylinder or gas tank (7) is also provided, for which purpose the device can be supplied with two or more small cylinders (7) easily
replaceable

In the case that the diver, to be considered indisposed, or for any other reason, intend to activate the device even when the maximum time of immersion or maximum depth, the inclusion of a manual activation command (9) associated with the control circuit (4), which facilitates said drive.

Finally it is worth mentioning that, as previously said, the device may incorporate optionally signaling means to facilitate location of the diver.

Claims (5)

1. Safety device for divers, specifically for the practice of "lung" diving, which being designed to exceed a preset time of diving and / or a threshold of depth considered as dangerous, automatically cause the diver to rise to the surface by flotation is characterized in that it is constituted from a clock (3) and a depth gauge (2) associated with a control circuit (4) that acts once the parameters of maximum immersion time and / or depth of diving on means (6) of swelling of a float (7) by pressurized gas associated with the device, fixing the assembly to the body of the diver or forming an integral part of his diving suit. 2. Safety device for divers, according to claim 1, characterized in that said inflation means of the float (7) materialize in a small gas cylinder under pressure, preferably air, the outlet of which is associated with an electro-valve (6) governed by the control circuit (4). 3. Safety device for divers, according to previous claims, characterized in that it incorporates an additional control (9) for activating the device manually. 4. Safety device for divers, according to previous claims, characterized in that it has a compact configuration, with the different electronic / electrical components properly sealed. 5.
