METHOD FOR RESCUING A PERSON FROM THE WATER AND A DEVICE FOR APPLYING THE METHOD

The invention relates to a method for rescuing a person from the water, and a device for applying the method.

In different accidents or mishaps, or corresponding occurrence, people fall into or in some other way end up in the water. Efforts should be made as quickly and as effectively as possible to save people who have fallen into the water. All vessels and public piers have accessible rescue instruments. A typical rescue instrument is the life preserver, which is thrown near the rescuee, whereupon the rescuee grabs the life preserver and floats on it until he/she is saved, or else he/she swims on the life preserver to safety.

Additionally, life rafts, or corresponding floating devices, are used, which open in the water. There are also different devices by which a rescue instrument, such as a life preserver or life rait, is thrown, shot, flung or dropped into the vicinity of the rescuee. All of these have the disadvantage that, although the life preserver, life raft, or corresponding floating device, can be aimed to the vicinity of the rescuee, the person must still swim to it, grab it and possibly lift him herself onto it and hereby further his/her own rescue. If, however, the rescuee is, for example, unconscious, tired or for some other reason may not be able to get a grasp on the rescue instrument, he/she cannot be saved in this way.

The object of the invention is to provide a method by which the disadvantages associated with the current methods will be eliminated. In particular, the object of the invention is to provide a method, which when used, will enable the rescuee to be lifted quickly and effectively to the surface of the water and to the life raft. Further, the object of the invention is to provide a device for applying the method, which is easy to use and functions reliably.

In a method implemented in accordance with the invention, a bar-like rescue device is conveyed into the vicinity of the rescuee and with the help , of the rescue device, a life raft which is packed together is conveyed underneath the rescuee and is then filled with a buoyant substance while it is under the rescuee, whereupon the rescuee is lifted to the surface of the water on the life raft as it rises. In a method implemented in accordance with the invention, the rescuer stays with the rescuee the whole time and with the help of the rescue device, guides the life raft under the rescuee. When the rescue device and the life raft are in the desired place, the life raft is filled in a way known per se with some conventional buoyant substance suitable for the purpose, such as gas, foam or corresponding substance. In this way, the life raft rises upwards in the water and because it is underneath the rescuee, it also simultaneously lifts him/her to the surface of the water. Thus, the rescuee is effectively raised to the life raft and to the water surface, where he/she is out of the immediate danger of drowning, without him/her having had to take any action.

In one advantageous application of the invention, the packed life raft is conveyed underneath the rescuee on the inside of the bar-like rescue device. The size of the bar-like rescue device is such that the packed life raft can go through it. Many life raft packs can be found on a vessel, and they can be fed one after another through the rescue device using a feeding and/or loading device suited for the purpose. After one life raft has been fed into the water, the rescue device can be moved to the location of the next rescuee and the next life raft can be fed under him her. Thus, many people can be saved using one rescue device. Life rafts are designed appropriately for the purpose and to fit on the pipe.

In another advantageous application of the invention, the packed life raft is conveyed on the outside of or along the bar-like rescue device underneath the rescuee. The life raft can be located in the end of the rescue device, whereupon it is launched from one end of the rescue device once it is in the right place underneath the rescuee. In this sort of application, the life raft pack is detachably attached to the end of the rescue device. After one pack has been launched, the next raft pack can be attached to the end of the rescue device and the next person who is in the water can be rescued. Thus, the same rescue device can be used for launching several different life rafts into the water.

In another application of the invention, the rescue device and the life raft pack are designed such that the life raft pack can slide along the outer surface of the rescue device to the end of the rescue device, or in its vicinity to the desired place. Thus also one rescue device can be used for feeding several life raft packs into the water.

In the following advantageous application of the invention, the life raft is connected to the rescuer with a rope-like element. By "rescuer" is meant thus either the person or the rescue vessel. Thus, the life raft cannot drift and the person on the life raft can be pulled on the life raft to safety to the rescuer and then lifted to safety. If it is a question of saving one person, he/she is pulled immediately to safety. If several people have fallen into the water, they can first all be saved on the life rafts and then pulled to the vessel and raised into the vessel.

In a further advantageous application of the invention, an observing instrument attached to the rescue device enables one to monitor the position of the rescue device in the water in relation to the rescuee. The use of such an observing instrument is important, so that the rescue device and the end of the rescue device can be observed the whole time and can be accurately moved to and underneath the rescuee.

A device formed in accordance with the invention comprises a bar-like rescue device and a packed life raft which fills up with a buoyant substance, and which is designed to be transferred underneath the rescuee using the bar-like rescue device. This kind of bar-like rescue device can be handled by one person and, using it, the life raft can be accurately and reliably positioned underneath the person in order to save him/her.

The invention will now be described in more detail with reference to the accompanying drawings, in which Figure 1 illustrates a certain description of a method carried out in accordance with the invention, in the phase in which the rescue device is being moved into the vicinity of the rescuee,
Figure 2 illustrates a situation, in which the life raft is being launched underneath the rescuee, and
Figure 3 illustrates the rescuee on the life raft.

The rescue equipment formed in accordance with Figures 1-3 comprises a bar-like rescue device 1, to which is connected a packed life raft 3, a rope-like element 4 and an observing instrument 6. The size and shape of the barlike rescue device can vary in different applications of the invention. In the application illustrated in the figures, the size of the bar-like rescue device 1 is such that one person can handle, hold and control it. Figure 1 illustrates the rescuer 5, which is a person on the vessel 7. The rescuer is holding the rescue device 1 with his/her hands and the rescue device is further supported by the shoulders of the rescuer.

In this application of the invention, the life raft contained in the pack 3 is located on the end of the bar-like rescue device 1. An observing instrument 6 has been attached in the vicinity of the end of the rescue device, said observing instrument comprising a buoyant float or corresponding device, which comes up from the water, which is attached to the rescue device such that it shows the position of the end of the rescue device. The observing instrument can be bright-colored or it can be equipped with a signal light or it can be made clearly distinguishable by some other means.

The rope-like element is made from conventional material known per se and it is connected to the rescuer by the rescue device. In another alternative, the rope-like element is on the outside of the rescue device, whereupon the rescue device can be re-used immediately to launch another life raft after the first life raft has been launched.

When one or more people 2 have fallen into the water, a rescue device formed in accordance with the invention is used. The rescuer positioned, for example, on the edge of the vessel, brings the bar-like rescue device to the rescuee. The rescue device should be positioned so that the end of the rescue device, and the life raft in it, is underneath the rescuee. Then the rescuer launches the life raft, which fills up with a buoyant medium. While it is filling, the life raft rises upwards to the surface of the water. Because the rescuee is on the life raft, the life raft lifts the rescuee as it rises. The rescuer can then pull the life raft to the vessel, pier, or other place, and lift the person who has fallen into the water to safety. If it is a question of an accident, in which several people have fallen into the water, the rescuee can be left in safety on the life raft for some time, to move to the next rescuee and get new rescuees onto other life rafts before lifting them. It is also possible to join two or more rafts together, whereupon they form a bigger whole. The rafts can be towed in a suitable way, to a protected place, for example, before the person/people is/are lifted to the vessel.

The structure of a bar-like rescue device foπned in accordance with the invention can vary significantly in different applications of the invention. In a certain application, the bar-like rescue device is hollow and the pack which forms the life raft is fed along a pipe to its position underneath the rescuee. In another application, the life raft is designed such that it can slide on the outside of the rescue device beneath the person in need.

In a third application, the rescue device is like a telescopic pipe in its structure, so that it can be stored in a small space. When the pipe is used, it is opened to its full length and taken to the rescuee.

The life raft is launched using the rescue device, or in some cases it is shot out automatically when it reaches the end of the launching device. The launch can occur mechanically or by remote control using conventional techniques known per se. It is also possible to position a transmitter on people, which launches the life raft when it is in the immediate vicinity of the rescuee. The life raft can be equipped in a conventional way with a transmitter. The bottom of it is a net-like material, perforated or other such material, which allows water to flow out of it.

The invention is not limited to these advantageous applications. The invention is versatile and its form can vary within the scope of the idea of the invention set forth in the claims.
