Description

  The water sports equipment of the present invention relates to water sports equipment such as marine sports that can float on the water of the sea, lakes, rivers, etc. The present invention relates to an exercise equipment that can be connected and made large.

  Various tools have been developed that can be transported by floating or floating on the water of the sea, lakes, or rivers, playing, or exercising. One of the most popular is known as a float. In addition, there is a float that is inflated with air from a PVC or the like into a shape of a dolphin or a turtle or a shape of a boat as a deformation of the float. However, these bulges are easily deformed and have insufficient stability. For example, there is an aquaplane known as water skiing. This is a person who rides one mono ski or two pair skis at the tip of a tow rope with a diameter of 5.5 to 6.5 millimeters called a toe rope from a motor boat and a length of 23 meters. It is intended to float and run over the water at a speed of 24 to 58 km / h. This general ski is 175 cm long and 17 cm wide and is made of plywood or plastic. In addition, buoyant synthetic resin beat boards or kick boards used for practicing legs in swimming practice are well known, but they are small in shape and cannot be said to have sufficient buoyancy. Is.

  Surfing is 1.5 to 2.7 meters long, 50 to 60 centimeters wide, and 7 to 10 centimeters thick wooden or polyurethane foam surfboards that are used by one person to balance and surf on both hands. (Trade name) is generally known. The board used for surfing is selected according to the rider's height, weight, experience, type of surfing and personal preference.

  In addition, board sailing or windsurfing has been developed. Unlike a yacht, this is a marine sports equipment that has quickly penetrated among young people because it is easy to carry and cheap. This board sailing is a combination of surfing and sail. Developed and conceived by the United States in 1970, spread to Europe in 1971, and introduced to Japan in 1973. The board weighs about 28kg, is 3.7 meters long and 60 centimeters wide, and can be easily carried by car as described above, and can be enjoyed anywhere with water and wind. In 1983, he recorded a speed of 57.08 km / h in the United States.

  Conventional water skis, surfboards, and board sailing are widely known (see, for example, Non-Patent Document 1).

  However, these water skis, surfboards, and board sailing require practice and skill as competitions take place. In order for ordinary people to easily carry it to the seaside, lake shore, etc. and enjoy it easily as a marine sport, development of a water exercise equipment that can be handled more easily and safely without the need for techniques such as sailing and surfing. It has been demanded.
