WATER RESCUE DEVICE

A water rescue device for connecting a sling includes a frame body having a loading seat; a hollow post erected on the loading seat; a plurality of connecting rods connected between the hollow post and the frame body; and a submerged weight disposed under the loading seat. One end of the sling passes through the hollow post to connect the submerged weight.

BACKGROUND OF THE INVENTION

1. Technical Field

The invention relates to rescue devices, particularly to surface water rescue devices for rescuing a patient who is afloat on the surface of a body of water.

2. Related Art

When a person is afloat on a water surface to be rescued, a sling with a rescue device is usually used to pull him or her up. However, the sling is fixed above the rescue device, so the rescue device tends to sway. Such sway is very dangerous and is easy to fling away the rescued person again.

When the rescue device is declined over the water surface, the rescue device is easy to be terribly shifted and the rescued person is hard to enter the rescue device.

SUMMARY OF THE INVENTION

An object of the invention is to provide a water rescue device, which can effectively reduce sway or shift over the water surface.

To accomplish the above object, the water rescue device includes a frame body having a loading seat; a hollow post erected on the loading seat; a plurality of connecting rods connected between the hollow post and the frame body; and a submerged weight disposed under the loading seat. One end of the sling passes through the hollow post to connect the submerged weight.

DETAILED DESCRIPTION OF THE INVENTION

The invention provides a water rescue device for use on a water surface, such as sea or river, as shown inFIG. 2.

Please refer toFIGS. 1 and 3. The rescue device is used to connect to a sling7and includes a frame body1, a hollow post2, a plurality of connecting rods3and a submerged weight5. The invention preferably includes a receiving member4.

The frame body1is provided with a loading seat101and includes a bottom frame10and a side frame11erected on and around the bottom frame10. The side frame11is of a C-shape with a notch, but not limited to this shape. A person can enter the frame body1through the notch. The frame body1is provided with floaters13and can float on a water surface. The side frame11has a horizontal rod111to which the floaters13are fixed.

The loading seat101is arranged in the bottom frame10and may be a soft mesh made of ropes or a rigid mesh made of metal wires. Furthermore, the loading seat101can be added with a plurality of supporting rods102(as shown inFIG. 1) connected between the bottom frame10and the hollow post2for reinforcement.

The hollow post2is erected on the loading seat101and connects with the supporting rods102. The connecting rods3are connected between the frame body1and the hollow post2. In the embodiment, the connecting rods3are connected between the side frame11and the hollow post2. Their junctions are located at an upper end of the side frame11and an upper portion of the hollow post2. Other locations are also available.

The submerged weight5is arranged under the loading seat101. An end of the sling7passes through the hollow post2to connect the submerged weight5. Please refer toFIGS. 2 and 4. The rescue device hung by a boom81can keep stable by the submerged weight5. The submerged weight5may be a metal ball.

The receiving member4is disposed under the loading seat101and connects a bottom end of the hollow post2for receiving and holding the submerged weight5. The receiving member4is of a flared shape. The submerged weight5can be simply received in the receiving member4when the submerged weight5is pulling up by the sling7.

As shown inFIG. 2, when a ship8nears the person to be rescued, the rescue device is declined from the boom81to make the rescue device float on the water surface by the floaters13. As shown inFIGS. 3 and 4, the sling7keeps releasing to make the submerged weight5leave the receiving member4, so that the rescue device can be stabilized. After the rescued person sits on the loading seat101, the sling7is furled to pull up the submerged weight5and the rescue device. Because a main portion of the sling7is received in the hollow post2and the hollow post2is fixed on the loading seat101, the rescue device can keep stable even when it is in the air.

While the forgoing is directed to a preferred embodiment of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. As such, the appropriate scope of the invention is to be determined according to the claims.
