Self-inflating water rescue device

Abstract

A self-inflating water rescue device (1) consisting of a belt (2) for fastening to the waist and a lifebelt (5) connected to a compressed gas cartridge (4) attached to an opening trigger (3), the belt (2) and the lifebelt (5) being connected to each other by a safety strap (9), one end of a release cord (11) is connected to the opening trigger (3), the other end of the cord (11) being routed outside the lifesaving device (1), the lifebelt (5) being provided with a release valve (12) where applicable, and characterized by that a storage pocket (8) is formed on at least a part of the outer side of the belt (2) by a fixed wall (6) and an sliding (loose) wall (7), the lifebelt (5) being arranged in the storage pocket (case) (8), the outer part of the belt (2) being itself a fixed wall (6) of the pocket (8), the lifebelt (5) has a basically interrupted perimeter circle shape, the ends (13) of which at the interruption are overlapping when filled with gas, and when not filled with gas the lifebelt (5) is folded into the pocket (8) in an accordion/fan-like manner.

Claims

1. A self-inflating water secure device, consisting of a belt secured to the waist and a life belt connected to a pressurized gas cylinder attached to an opening device. On at least one part of the outer wall of the belt, there is a storage pocket (case) formed by a fixed wall and a loose, sliding wall, the former of which is the outer wall of the belt itself. The life belt is arranged in the storage case, and the belt and the life belt are connected to each other by a safety strap. A release cord is connected to the opening device on one end, the other end is placed outside the device. The life belt is also provided with a release valve, characterized in that the life belt has a substantially interrupted circumferential shape, the interrupted ends of which, when filled with gas, are overlapping at the interruption on top of each other. In a gas-free state, the life belt is folded into the case, much like the shape of a fan or an accordion.

2. Device according to claim 1, characterized in that the cross-section of the life belt is the smallest at the ends, is continuously increasing in size from the ends towards the middle, and is the largest at the same distance from the ends.

3. Device according to claim 1 or 2, characterized in that the loose opening wall of the storage pocket (case) is closed with a Velcro fastener to the fixed wall.

4. Device according to any one of claims 1 to 3, characterized in that the discharge valve is designed to be a human-powered valve also suitable for air injection.

5. Device according to any one of claims 1 to 4, characterized in that the life belt is provided with compartments partitioned by internal divider walls, in which fill valves are installed, while discharge valves are integrated into the outer peripheral edges of the compartments.

6. Appliance according to any one of claims Ito 5, characterized in that the outer wall of the belt is a fixed wall of the case itself.

Description

SUMMARY OF THE INVENTION

[0010] The purpose of the model is to make previously known water rescue devices safer and more usable, i.e., to develop a rescue device and not a swimming aid. It has now been found that if the belt is shaped such that it surrounds the body like a pair of scissors or pliers with protruding ends, the device can greatly adapt to the circumference of the body. Attachment to the waist with the second belt can provide fastening of the life belt to the wearer in a known manner. In addition, we can clearly position the life belt under the armpit to ensure that the wearer is in a properly secure posture after falling into the water without them having to do anything. Therefore, it is clearly suitable for keeping a person in the water on the surface.

[0011] The model consists of a self-inflating water rescue device, consisting of a waist-belt and a life belt connected to a pressurized gas cylinder attached to an opening device. On at least one part of the outer wall of the belt, there is a storage pocket (case) formed by a fix wall and a loose, sliding wall, the former of which is the outer wall of the belt itself. The life belt is arranged in the storage case, and the belt and the life belt are connected to each other by a safety strap. A release cord is connected to the opening device on one end, the other end it is placed outside the water rescue device. The life belt is also provided with a release valve. Essentially, the life belt has a substantially interrupted circumferential shape, the ends of which are overlapping at the interruption—in the gas-filled state—and folded into the case much like in the shape of an accordion/fan when the life belt is gas-free.
