HUT60638A - Small-size, self-inflating, life-saving device serving for preventing drowning, keeping on water surface, weared on neck, available anytime while being in water particularly in case of emergency - Google Patents

Abstract

The invention relates to a self-inflatable life-saving apparatus, especially for personal saving, which can be used for preventing and avoiding drowning, by keeping the head above the water surface when weared around the neck. The present invention provides for an apparatus containing a waterproof inflatable bag (3), which can be placed on the body, preferably around the neck of the person to be saved, as well as a gas bag (13) connected to said bag (3) by means of a rapid action valve assembly (6, 8, 9, 11, 12) provided with an operating organ.

Description

BACKGROUND OF THE INVENTION The present invention relates to a small self-inflating rescue device for preventing water drowning, which is carried on the surface of the neck and is worn on the neck at all times, especially in emergencies.

The rescue device of the present invention is recommended for use by persons who can swim but are in an emergency due to storm, fatigue, accident, distress, and those who are unable to swim while in or near water for work, pleasure or other reasons.

The rescue device is a small, self-inflating, self-inflating structure with a variety of fashionable designs, fitted with a neckband and several sizes depending on body weight.

The devices known to date on the surface of the water are mainly designed for non-swimmers, eg. a swim vest, a swim belt that needs to be replenished on the shore, large in size and placed on the upper body, chest or upper arm.

Our goal is a self-inflating rescue device that is simple, low-volume, lightweight and can be deployed quickly with a jerk when needed. All of this is necessary to ensure that it does not interfere with swimming, movement and is immediately applicable in the event of an unexpected occurrence.

It is a further aspect of the invention to realize that a significant volume of the floating equipment used so far was not in the water but in the air during their use and therefore had no role in the creation of buoyancy. All of this is a consequence of wearing on the breast. Therefore, we recommend a neck-positioning that allows the person's head to be kept afloat with the smallest bag volume needed,

BACKGROUND OF THE INVENTION The present invention relates to a self-inflating rescue device worn around the neck consisting of three main parts: the bag / 3 /, the valve / 6, 8, 9, 11, 12 / and the gas container / 13 /, the rescue device with the neck / 1 / can be attached to the neck,

The buoyancy of the rescue device according to the invention is provided by the bag (3), which may be of different shapes. The most preferred shape is a toroid around the neck, or the like, which may be a single-space toroid or a toroid having a slit that divides its interior. The latter shape can be enclosed in a small volume and encircles the neck under the influence of gas pressure. Of course you can use the necklace / 1 / to guide you.

The rescue device according to the invention can be made with the outside of the bag (3) or with the gas tank (13) located inside the bag. The gas container contains high pressure compressed or liquefied gas,

Another embodiment of the rescue device according to the invention / 2. Fig. 1b ( _f) does not use a high pressure gas container but a multi-chamber gas container (17) which contains separate chemical substances. The gas produced by the reaction of these materials serves to deform the bag (3).

The rescue device according to the invention may be formed by various valves which operate by pulling, pressing or twisting.

The rescue device according to the invention is a possible example. Embodiment of the present invention is described in more detail, wherein

Figure 1 is a schematic sectional view of the device according to the invention; version/

Figure 2 is a schematic sectional view of another possible embodiment of the device according to the invention; version/

As shown in Figure 1, the rescue device of the present invention includes a gas container (13) which is hermetically sealed with a stationary valve body (12), a sealing ring (lo), and a rubber sleeve (11) and a movable valve body (6) the gas pressure and the coil spring / 8 / hold in the closed position. The movement of the movable valve body / 6 / from the open position to the closed position is prevented by the nails worked out on its own and the stationary valve body / 12 /.

This allows the gas to flow out of the gas tank / 13 / into the bag / 3 / through the stop bore / 15 /.

The bag (3 /) is hermetically connected to the moving valve body (6) directly by means of the retaining body (5) and by inserting the rubber ring (7).

The bag / 3 / is guided by s / 1 / by the belt rings / 2 /.

The bag (3) is in the folded position in the protective sleeve (4), which is made up of two halves and disintegrates under the action of the refillable bag (3), thus allowing it to be positioned around the neck (3).

• ··· · ··· • · · · ·······

The rescue device according to the invention is actuated by pulling the switch disc (14) and causing the movable valve body (6) to move and open the valve by pulling the stationary valve body (12) in the opposite direction. When the valve is so open, the gas flows into the bag / 3 / and creates a volume change to maintain buoyancy on the surface of the water,

Variant II of the rescue device according to the invention is shown in FIG. 2 and differs from Variant I in that the gas container (13) is a multi-chamber gas container (17), in which chambers are separated by chemical substances,

With the displacement of the long stem valve body / 16 /, whose movement is also produced by the pulling of the switch discs / 14 /, the closing body / 2o / moves and the interacted materials react, the gas produced through the closing bore / 15 / into the bag / 3 / y.

Of course, the construction of the rescue device which is the object of the invention is not limited to the embodiment of the device exemplified in connection with Figures 1 and 2, but a wide variety of similar embodiments can be made; the scope of the invention is not altered by replacing components with other designs.
