Description

An inflatable spherical hood for protection against drowning and submersion in avalanches

technical field

The present invention relates to a compact, portable, inflatable spherical refuge equipment, which can ensure the integrity of the wearer through its full cover deployment in various environments, especially in aquatic environments and mountainous areas against avalanches. Protection, lifesaving and survival.

Background technique

In the marine environment, there is no existing portable equipment traditionally used that integrates the three functions of lifesaving, overall protection and optimization of survival time, and ensures protection against hypothermia and predator attack. In fact, life buoys or inflatable vests are not included in the above mentioned equipment, which are only a solution for a single drowning person (and also in seas where there are no strong waves). As for lifeboats, they are not portable, thereby reducing their accessibility and maneuverability, and given the risk of capsizing, it is equally vulnerable when exposed to rough seas.

In alpine areas, there is also no existing equipment that can guarantee effective protection against avalanche flooding and the resulting personal injury, and provide shelter against the danger of cold ground in the event of a death on an alpine area.

Contents of the invention

On the contrary, the equipment of the present invention makes up for the deficiencies and inconveniences of all the above equipments. In fact, it is light and portable, because it can be worn like a vest (chasubles). The primary feature of this equipment is that when activated by the synchronized activation device, the internal airbags of this equipment inflate, and this equipment instantly deploys in order to cover the entire wearer, thus ensuring that the wearer is safe under various conditions. The overall protection of the wearer, especially at sea or in alpine areas against avalanches or in survival environments.

、受到螺旋桨或者由自然生成或由沉船产生的旋涡的伤害。此外，通过使得穿带者避免与水接触，本装备解决了溺水、体温过低和捕食性动物袭击(鲨鱼对受伤的海难者进行袭击)等问题，很大程度地延长了海难者在海水中的生存时间。由于它的尺寸和在水上鼓起的特点，与使用救生圈和救生衣相比，成倍增强了遇难者的可见度。In a marine environment, this floating massive sphere—by virtue of its size and spherical shape—guarantees a long-lasting and constant afloat even in rough seas, and protects against being sucked in by undercurrents, swells

, taking damage from propellers or vortices generated naturally or by sunken ships. In addition, by keeping the wearer out of contact with water, the device solves the problems of drowning, hypothermia, and predator attacks (sharks attacking injured shipwrecks), greatly prolonging the life of the shipwrecked in seawater. survival time. Due to its size and the characteristic of swelling above the water, the visibility of victims is exponentially enhanced compared to the use of buoys and life jackets.

In mountainous areas, this kind of equipment that can expand into a huge sphere will not be submerged under the impact of high avalanches at any angle, and can only roll to farther places like a kicked ball. The kit also ensures protection against trauma thanks to the refuge space provided by the integral hood protection of the ball and finally, in survival mode, resists the cold when used as an igloo. Also, due to its size and contrasting color to the snow (example: orange), it exponentially enhances the visibility of victims compared to igloos and mountainside shelters, which are useful for aerial searches The means are completely invisible.

According to a specific embodiment, there are:

The inflatable inner bladder, instead of being a single bladder (Fig. 2.a), may in another variant be two bladders (Fig. 2.b).

Activation box with sliding cord (fig. 3) to control the firing mechanism (dispositif de percussion) of the gas bottle for optimal operation.

Detailed ways

Referring to these views, the device is in the shape of a large sphere (1) and includes internal air cells (2 or 3) which, when inflated, instantly deploy the device to completely enclose the wearer's (6) body, thereby ensuring Lifesaving, protection and survival of the wearer in various environments, especially in aquatic environments and alpine areas.

Both the outer cover of the device (1) and the inner airbag (2 or 3) are made of lightweight, strong, water-resistant material, which is protectively assembled to ensure tightness at seam points.

The purpose of the starter box (10) controlling the firing device (11) of the gas bottle (12) is to simplify and optimize the firing of this gas bottle, as: driven by the sliding pull cord (28 or 29), "L" The shaped part (15) compresses the spring (16), which spring (16) pushes the plug (17), which in turn pulls the activation pull cord (18).

The central synchronous starting device (22) comprises a hook (23) hinged (24) on a sliding device (26) mounted on two tension springs (27). In the engaged state, the hook (23) grips the plane (α) firmly. Released by the pull of the operating rod (20) hinged (21) on the base (22), the hook (23) suddenly pulls strongly and sharply the two sliding pull cords, one (28) controls the opening of the upper hemisphere gas bottle , the other (29) passes through the slot (F) to connect the hook (23) to control the opening of the gas bottle in the lower hemisphere. Furthermore, under the pressure of the spring (25), the hook (23) is lifted and releases the two sliding cords (28 and 29), the release of which is facilitated by a ramp (30) , the slideway is used as a stop for the pull cord.

The harness system (8), the crotch strap (9) and the 4 or 6 restraint straps (7) of the device according to the invention secure the wearer (6) to the device (1) according to the invention. Two elastic straps (34) terminating in buckles (35) secure the device to the wearer, like a belt, the two buckles of which pass through two lateral slots (33) The two fork joints (32) are hooked to the shaft (31) attached to the slide (26) and, when disengaged, are automatically disengaged by the pullback of the slide.

The kit of the present invention is particularly useful in providing a portable inflatable refuge space for lifesaving, overall protection and survival, particularly suitable for use in aquatic environments where direct body contact with the water surface is avoided through its function, which greatly prolongs the survival time of victims in cold waters, and can effectively prevent drowning, hypothermia and predator attacks (sharks attack injured shipwrecks) or injuries caused by protrusions on the reef . Thanks to its large volume when inflated, it prevents it from being driven towards the bottom by waves, swells, or sucked in by natural waters, whirlpools created by shipwrecks. Finally, due to its large size and characteristic of swelling out of the water, it multiplies the visibility of the shipwrecked person compared to a buoy or lifejacket. In mountainous areas, the refuge equipment used for lifesaving, overall protection and survival in the form of such a huge sphere is of course the only way to effectively ensure that it is prevented from being submerged by an avalanche. Submerged, and, thanks to the sphere's integral hood, the body is protected from collisions, thus protecting from injury and eventually, when needed, it can be unfolded into an igloo against the cold. Also, due to its size and contrasting color to the snow (example: orange), it exponentially enhances the visibility of victims compared to igloos and mountainside shelters, which are useful for aerial searches The means are completely invisible.
