However, it is not so easy for people to paddle and kick in the water to generate upward force. Most beginners paddle randomly in the water, not only fail to rise, but produce downward force. It takes a long time to learn to swim
[0003]As for devices that can assist swimming, the most common ones are swimsuits or lifebuoys or other buoyancy devices. Swimming suits or lifebuoys rely on buoyancy to support people in The water surface allows learner swimmers to row and kick with confidence, but this delays learning to swim even more, because people have already obtained the upward support, and people do not need to produce this important upward support when rowing and kicking. The victim is thrown into the deep water with his body empty and let him struggle and kick for a while before being rescued. After doing this many times, he will soon learn to swim.

Embodiment Construction
[0011] Below in conjunction with accompanying drawing, the lifesaving foot skirt cover in water is further described.
[0012] figure 1 Shown is an exterior view of one of a pair of water survival foot skirts. The lifesaving foot skirt cover in water is all made of cloth material, and it will show its shape characteristics when it is worn on people's shanks. When it is in standby, it is folded into a small ball and has no fixed shape. The stockings (3) of lifesaving foot skirt cover in water are the best with elastic cloth matter material, because elastic cloth matter stockings can be close to people's shank, are not easy to slip off. The stockings (3) in the figure can be put on people's knees (2), and this length allows two umbrella-shaped aprons (4) to be sewed on different parts of its middle calf. Umbrella-shaped apron (4) includes: inner circumference (5), outer circumference (6), lower circumference (8), drawstring (7), wherein inner circumference (5) is oversewed on ...

The invention discloses an underwater lifesaving foot skirt sleeve. Two umbrella-shaped aprons are sewed in the middle of each of paired elastic cloth stockings. The inner edge of each umbrella-shaped apron is fixedly sewed on the leg of the corresponding stocking in a sleeve mode, a plurality of pulling ropes are evenly distributed on the outer edge of each umbrella-shaped apron, and the other ends of the pulling ropes are connected to the apron cylinders of the lower edges in a sewing mode. The umbrella-shaped aprons are similar to parachutes. When a person raises the shanks upwards in the water, the umbrella-shaped aprons contract to be adhered to the shanks, and no resistance is generated; when the person kicks the shanks downwards, the umbrella-shaped aprons unfold to generate large resistance, so that upward lift force is provided for the drowning person. The underwater lifesaving foot skirt sleeve entirely made of cloth is foldable and easy to carry, and the upward lift force can be generated when people incapable of swimming kick their legs randomly in the water to enable the heads of the people to be always exposed above the water surface.
Description
technical field [0001] The invention relates to a foot cloth skirt cover which is worn on the calf of the foot and has an auxiliary function for swimming. Background technique [0002] Many animals are natural swimmers, such as: cows, mice, snakes, dogs, etc. They do not need to learn to swim, they will swim forward after falling into the water. The reason why these animals are born to swim is partly because their body structure is suitable for floating. Swimming on the water surface, such as: a cow has a big belly, and there is a lot of gas in its stomach to make it float on the water surface. Other animals such as mice and dogs can also float on the water surface because of the gas in their bodies. Just paddle forward . But human beings can't float on the water with their whole body, because their body weight and volume just make them sinkable. This Achilles heel of human beings makes them have to learn to swim. The most basic movement of swimming is not to enable people...
