Definitions
- the present invention relates to a rescue device for bodies, like human beings or cargo, fallen into the sea.
- the most well-known rescue device for drowning persons is the swimming or life jacket serving to lend additional buoyancy to the drowning person in order to keep the person's head above water and to prevent immediate drowning.
- a swimming jacket may save the life of a person because the swimming jacket enables the person to swim more easily to the shore or to keep the person floating long enough to be picked out of the water by others.
- At sea or in other great waters such a conventional swimming jacket saves life of a drowning person only in very exceptional cases. The reason for this is that drowning persons die due to undercooling before they are found. Depending on the temperature undercooling sets in already after fifteen to sixty minutes after which the drowning person dies quickly.
- a swimming jacket saves a drowning person from drowning, but does not offer sufficient changes to give others the possibility to save the drowning person.
- the distance between the ship and the drowning person increases quickly most of the time and it takes some time before the ship is able to return to the drowning person, if this is possible anyhow.
- Tracing by airplanes or helicopters is extremely difficult due to the small surface area of the drowning person, while the tracing operation is often extra complicated by bad weather. Many efforts to improve and further develop swimming jackets have not led to an effective survival means.
- Another big problem with which the present invention is concerned is the problem of many millions of tons of ship's load disappearing into the sea every year and which cannot be found back anymore. This not only leads to a destruction of capital goods, but often causes risks of environmental pollution.
- the object of the present invention is to provide a rescue device for bodies fallen into the sea, with which an effective solution to the problems described is offered.
- the rescue device is characterized by a body part attached to the body by attachment means, a flexible elongate connecting member fixed to the body part on one hand and to a rising means on the other hand, said rising means having a small size in its inoperative position and is expandable to an operative position in which it exerts an upward lift in air and is preferably radar reflecting, expansion means for bringing the rising means from the inoperative to the operative position, and actuating means for activating the expansion means.
- the rescue device will be made operative automatically or by actuation by the drowning person, after which the rising means releases from the body and will float at a distance above the sea level and fixed to the connecting member. Due to this rising means floating high in the sky and which may also have a large surface area, it is much easier to locate the drowning person optically while, in particular when the rising means is equipped with special radar reflecting means, it also enables an effective radar tracing operation. In this way the chances of a drowning person being found before undercooling of the body occurs, are substantially increased.
- the actuating means of the rescue device should function automatically and the connecting member should have such a length that, when the load has sunk to the bottom, the rising means is still able to float above sea level.
- the length of the connecting member may vary from several dozens of meters up to many hundreds of meters depending on the sea over which the load should be transported.
- the rising means floating above the sea will simplify the location of the position where the load has sunk to a large degree.
- the rising means consists of a balloon preferably coated with lacquer.
- This metal lacquer may serve to make the balloon gastight on the one hand and to give the balloon excellent radar reflecting properties on the other hand.
- other radar reflecting techniques may be used instead or in addition.
- the shape of the balloon may be selected depending on the requirements.
- the expansion means conveniently comprises a container to fill up the balloon with gas which is lighter than air at ambient pressure, said container being connected to the balloon through a valve actuated by the actuating means and containing a pressurized gas or a solid material producing hydrogen by its reaction with water.
- the hydrogen producing solid material is for example an alkali metal and/or hydrides thereof.
- the rescue device may be operated manually or be actuated automatically, for example by contacting water, or by the pulling force of a life line with which a person is connected to the ship.
- the actuating means of a rescue device for load may respond by its contact with water or by the pressure which it undergoes when it sinks.
- the rescue device includes a cylindrical casing which contains in a practical embodiment three exchangeable parts: a first part containing the rising means, a joining second part having the expansion means and a third part containing the connecting member.
- the exchangeability of the parts may be used both for replacing a part by an equal, but new part and for selectively combining parts having a different volume.
- rescue device with conventional rescue or survival means such as a signal transmitter, preferably a radio beacon, connected to the rising means, a fishing line, a colouring cartridge and the like.
- a signal transmitter preferably a radio beacon
- Receiving a signal from a radio beacon suspended from the rising means in emergency cases is much more effective than a radio beacon fixed to the body of the person which can be received for only a part of the time because the radio beacon will often be under water.
- the rescue device according to the invention may also be attached to the body of a person in another way, for example by means of belts or the like, it is favourable to combine the rescue device with a life jacket, wherein the rescue device may both be attached to the life jacket later on or be integrated in the design of the life jacket.
- the rescue device it is an object to make the rescue device as small and lightweight as possible so that it gives a minimum hindrance when it is worn.
- the balloon will then be collapsed to a minimum volume, the gas within the container will be compressed to a minimum volume and the connecting member will be wound such that a reliable unwinding is guaranteed.
- well-known techniques are available which may be used with some modifications.
- the rescue device not only serves for locating the load but also for recovering it eliminating the need for divers or diving equipment.
- Fig. 1-3 illustrate the principle of the rescue device according to the present invention in use with a drowning person.
- Fig. 4 shows on an enlarged scale and in front view the rescue device of Figs. 1-3.
- Fig. 5-9 illustrate the principle of the rescue device according to the invention in an embodiment for ship's cargo load.
- FIG. 1 show embodiments of the rescue device according to the invention which is intended to rescue bodies fallen into the sea, wherein there is made a distinction between bodies of living souls, in particular human beings, and of objects, in particular goods transported overseas, that is by boat, aeroplane or the like.

Abstract
A rescue device for bodies, such as of human beings or cargo load, fallen into the sea, includes a body part for attachment to the body, a long line attached to the body part on one end and to the other hand. The balloon is folded to a small size in its inoperative position and may be inflated to an operative position in which it exerts an upward lift in air. Preferably, the balloon is radar reflecting. A lightweight gas effects the inflation of the balloon from the inoperative to the operative position. There is provided a valve which can be opened to allow the gas into the balloon.
Description
- The present invention relates to a rescue device for bodies, like human beings or cargo, fallen into the sea.
- The most well-known rescue device for drowning persons is the swimming or life jacket serving to lend additional buoyancy to the drowning person in order to keep the person's head above water and to prevent immediate drowning. In small waters such as rivers and lakes such a swimming jacket may save the life of a person because the swimming jacket enables the person to swim more easily to the shore or to keep the person floating long enough to be picked out of the water by others. At sea or in other great waters such a conventional swimming jacket saves life of a drowning person only in very exceptional cases. The reason for this is that drowning persons die due to undercooling before they are found. Depending on the temperature undercooling sets in already after fifteen to sixty minutes after which the drowning person dies quickly. Hence, in most cases a swimming jacket saves a drowning person from drowning, but does not offer sufficient changes to give others the possibility to save the drowning person. When the drowning person has gone overboard from a ship, the distance between the ship and the drowning person increases quickly most of the time and it takes some time before the ship is able to return to the drowning person, if this is possible anyhow. Tracing by airplanes or helicopters is extremely difficult due to the small surface area of the drowning person, while the tracing operation is often extra complicated by bad weather. Many efforts to improve and further develop swimming jackets have not led to an effective survival means.
- Another big problem with which the present invention is concerned, is the problem of many millions of tons of ship's load disappearing into the sea every year and which cannot be found back anymore. This not only leads to a destruction of capital goods, but often causes risks of environmental pollution.
- The object of the present invention is to provide a rescue device for bodies fallen into the sea, with which an effective solution to the problems described is offered.
- For this purpose the rescue device according to the invention is characterized by a body part attached to the body by attachment means, a flexible elongate connecting member fixed to the body part on one hand and to a rising means on the other hand, said rising means having a small size in its inoperative position and is expandable to an operative position in which it exerts an upward lift in air and is preferably radar reflecting, expansion means for bringing the rising means from the inoperative to the operative position, and actuating means for activating the expansion means.
- According to these features and in case of a drowning person, the rescue device will be made operative automatically or by actuation by the drowning person, after which the rising means releases from the body and will float at a distance above the sea level and fixed to the connecting member. Due to this rising means floating high in the sky and which may also have a large surface area, it is much easier to locate the drowning person optically while, in particular when the rising means is equipped with special radar reflecting means, it also enables an effective radar tracing operation. In this way the chances of a drowning person being found before undercooling of the body occurs, are substantially increased.
- In case of attachment to ship's load the actuating means of the rescue device should function automatically and the connecting member should have such a length that, when the load has sunk to the bottom, the rising means is still able to float above sea level. In practice this means that the length of the connecting member may vary from several dozens of meters up to many hundreds of meters depending on the sea over which the load should be transported. In any case, the rising means floating above the sea will simplify the location of the position where the load has sunk to a large degree.
- In the most practical embodiment, the rising means consists of a balloon preferably coated with lacquer. This metal lacquer may serve to make the balloon gastight on the one hand and to give the balloon excellent radar reflecting properties on the other hand. Of course also other radar reflecting techniques may be used instead or in addition. The shape of the balloon may be selected depending on the requirements.
- The expansion means conveniently comprises a container to fill up the balloon with gas which is lighter than air at ambient pressure, said container being connected to the balloon through a valve actuated by the actuating means and containing a pressurized gas or a solid material producing hydrogen by its reaction with water.
- For pressurized gas one may consider helium or hydrogen, while the hydrogen producing solid material is for example an alkali metal and/or hydrides thereof.
- In case of drowning persons the rescue device may be operated manually or be actuated automatically, for example by contacting water, or by the pulling force of a life line with which a person is connected to the ship. The actuating means of a rescue device for load may respond by its contact with water or by the pressure which it undergoes when it sinks.
- In particular in the embodiment for drowning persons the rescue device includes a cylindrical casing which contains in a practical embodiment three exchangeable parts: a first part containing the rising means, a joining second part having the expansion means and a third part containing the connecting member. The exchangeability of the parts may be used both for replacing a part by an equal, but new part and for selectively combining parts having a different volume.
- Of course it is possible to equip the rescue device according to the invention with conventional rescue or survival means such as a signal transmitter, preferably a radio beacon, connected to the rising means, a fishing line, a colouring cartridge and the like. Receiving a signal from a radio beacon suspended from the rising means in emergency cases is much more effective than a radio beacon fixed to the body of the person which can be received for only a part of the time because the radio beacon will often be under water.
- Although the rescue device according to the invention may also be attached to the body of a person in another way, for example by means of belts or the like, it is favourable to combine the rescue device with a life jacket, wherein the rescue device may both be attached to the life jacket later on or be integrated in the design of the life jacket. Of course it is an object to make the rescue device as small and lightweight as possible so that it gives a minimum hindrance when it is worn. The balloon will then be collapsed to a minimum volume, the gas within the container will be compressed to a minimum volume and the connecting member will be wound such that a reliable unwinding is guaranteed. For these three parts well-known techniques are available which may be used with some modifications.
- With respect to the rescue device which is particularly intended for use with cargo load it is noted that it is very favourable when it is also provided with engagement means connected to the load and to which a hoisting means may engage which is guided along the connecting member to the load.
- In this way the rescue device not only serves for locating the load but also for recovering it eliminating the need for divers or diving equipment.
- The invention will hereafter be elucidated with reference to the drawings very schematically showing embodiments of the invention by way of example.
- Fig. 1-3 illustrate the principle of the rescue device according to the present invention in use with a drowning person.
- Fig. 4 shows on an enlarged scale and in front view the rescue device of Figs. 1-3.
- Fig. 5-9 illustrate the principle of the rescue device according to the invention in an embodiment for ship's cargo load.
- The drawings show embodiments of the rescue device according to the invention which is intended to rescue bodies fallen into the sea, wherein there is made a distinction between bodies of living souls, in particular human beings, and of objects, in particular goods transported overseas, that is by boat, aeroplane or the like.
- First of all, the embodiment of the rescue device for human beings is illustrated with reference to Figs. 1-4. In Figs. 1-3 there is shown a rescue device generally indicated with
reference numeral 1 and attached to a swimming orlife jacket 2 which is tightly worn around the body of a person which, in this case, is involuntary fallen into the sea one way or another and who should be rescued by others. For this purpose the rescue device can be actuated automatically or as a result of operation by the drowning person self. Then, according to Fig. 2, aballoon 3 of therescue device 1 is inflated with a gas which has less density than air, such as hydrogen, helium or the like, which balloon may rise and remains connected to the drowning person through an elongate connecting member, in particular aline 4, at a sufficient distance above the drowning person - a height of 10-30 meter above the water level is conceivable - in order to be well detectable both optically and by a radar installation. For the purpose of a tracing operation by means of radar theballoon 3 may be constructed such or may be equipped with such means that radar beams are being reflected. It is for instance possible to spray the balloon with a metal lacquer having the further advantage of making the elastic balloon gastight. On the other hand it is also possible to use other techniques, such as aluminium strips or the like. Also a signal transmitter may be suspended from theballoon 3 in order to transmit emergency signals, for example radio signals, high above the water level, which signals may be continuously and well received due to the high point of transmission. If a balloon or other rising means is used causing sufficient upward lift in the air, an additional effect may be obtained in that the drowning person is pulled up partly out of the water as a result of which undercooling starts less quick, in particular if the whole breast portion is above water. Consequently, the invention not only increases the chances of a drowning person being found, but also provides more time to pick up a drowning person from the water alive. - Fig. 4 schematically shows a possible embodiment of the rescue device according to the invention. In this exemplary embodiment, the rescue device is housed within a cylindrical casing consisting of three parts: a
first part 5 containing the collapsedballoon 3, asecond part 6 containing the means to blow gas into the balloon and a third part 7 in which theline 4 is wound. This third part 7 may also be indicated as body part which remains in contact with the body of the drowning person, in this case through thelife jacket 2, while both other parts get up into the air together with theballoon 3 and remain connected to the body part 7 through theline 4. The body part 7 may be attached to thelife jacket 2 or to the body of the person with belts or other attachment means, but it is of course also very well possible to integrate therescue device 1 fully in the life jacket. - The
first part 5 of the casing of therescue device 1 consists in this embodiment of two radial halves each comprising ahalf ring 8 having a groove in circumferential direction thereof. When not in use, both halves of thefirst part 5 are kept together in a manner to be described later on, but after actuating the rescue device both halves are released and theballoon 3 is set free to be expanded. Theballoon 3 may be made from elastic material such as rubber or a plastic and may be kept folded to a very small size for a longer period of time. Theballoon 3 has acollar 9 near its inflating opening, with which theballoon 3 is removably attached to thesecond part 6, such as by means of screw threads or a bayonet catch. With this releasable connection, thefirst part 5 and thesecond part 6 may be exchanged or replaced independent of each other. - In this case, the
second part 6 is constructed as a pressurized container for a compressed gas having a lower density in comparison with air, such as helium or hydrogen, which may arrive in theballoon 3 through an exit opening (not shown) which is closed and can be opened when the rescue device is actuated. Thevalve 10 or the like which can be opened is not shown in detail in Fig. 4, but is operated in this case by apull pin 11. Also around thesecond part 6 is a fixed ring orrib 12 having a circumferential groove in the outer surface thereof. - The third part 7 is partially pushed onto the
second part 6 and theline 4 which is wound within the third part 7 is fixed with its one end to aneyelet 13 on the underside of thesecond part 6 and is connected with its other end to the third part 7. Theline 4 is preferably made with a minimum weight and thickness and is for example a dracon cord and is wound within the third part in a reliable and tight manner in order to be able to unwind in a reliable manner when the balloon rises together with thesecond part 6. The third part 7 also has a ring orrib 14 having a circumferential groove. - The three parts 5-7 are held together by a
coupling element 15 comprising three part-circular clamps rings parts coupling element 15 from therings pull pin 11 is removably connected to thecoupling element 15 at 19, the removal of thecoupling element 15 simultaneously causes the opening of thevalve 10 of the pressurized container of thesecond part 6 through thepull pin 11 so that the rescue device is actuated. The removal of thecoupling element 15 can be effected manually, but it is also possible to attach a line to aneyelet 20 of thecoupling element 15, the line being connected with its other end to a sailing boat for example so that when the person wearing thisrescue device 1 gets overboard, thecoupling element 15 is immediately pulled off. In this manner the rescue device is automatically actuated. - Of course it is also possible to equip the
rescue device 1 with another automatic actuating means, for example in the form of a cartridge containing a material, such as phosphorus or alkali, reacting through contact with water, this reaction automatically activating thevalve 10 of the pressurized container of the third part. - Furthermore it will be clear that the
rescue device 1 may comprise further survival or signal means, such as a radio beacon, a fishing line, a colouring cartridge and the like. Theballoon 3 may also be replaced by or be combined with a kite-like member, which may even cause the drowning person to be carried along with the wind. The balloon may be inflated to a volume of example one or several cubic meters. - Figs. 5-9 show a further use of the rescue device according to the present invention for ship's load or other cargo, such as containers, boxes, rolls and the like. In this case the
rescue device 1 is sunk down on top of acontainer 21. The construction of therescue device 1 may be very different from that shown in Fig. 4, but therescue device 1 again comprises the rising means in the form of aballoon 3, the connecting member in the form of a line, cable, chain,tube 4 or the like and expansion means in the form of a pressurized container (not shown) for inflating theballoon 3. Theline 4 is, however, longer in this case since theballoon 3 should still float at a distance above the water surface also if thecontainer 21 has sunk to the bottom. In practice, theline 4 may hence have a length of many hundreds of meters. - Figs. 5-7 show the operation of the
rescue device 1 which is similar to the operation of the rescue device according to Figs. 1-3. However, in this case the actuating means of therescue device 1 will react to the contact with water or by the high pressure existing under water.
