Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for walking on water and playing in which a person can ride on the inside of a cylindrical floating body and walk on water or on land. Traditionally, many types of ships have been used as a means for humans to move on water, but most of them are powered by human power. A method is used in which paddles are operated by hand. However, this method... Disadvantages include severe hand fatigue during long-term operation, inability to use hands for other purposes during operation, lack of training for the limbs, and impossibility of operation on the ground. Additionally, a floating body with buoyancy that can hold the body's weight is attached to the legs. There is also a method that attempts to walk on water. This makes the floating body large and difficult to maneuver. However, it is not widely used due to its poor stability. It can also be used as play equipment on the water. Surfing There are windsurfing, etc., but these have the disadvantage that they do not function as play equipment at all when there are no waves or wind. +! The present invention solves the above-mentioned drawbacks, makes it possible to walk on water in the same posture as walking on land, and also makes water recreation such as swimming in the sea more enjoyable. The purpose of the present invention is to provide completely new play equipment for playing sports or enjoying competitions on the water, and furthermore, to provide exercise equipment that can be used for play or competition not only on water but also on land. In order to achieve these objects, the present invention has a cylindrical floating body, the basic structure of which is shown in FIGS. 1 to 9 of the accompanying drawings. Propulsion blades 2, 4, 5.13, etc. are provided on the outer circumference or flange of 3.12 radially with respect to the center of rotation, and the outer circumferential surface has a plane parallel to the center of rotation and a conical plane on both sides thereof. This device is characterized by a device for walking and playing on water, which has a part of the cylindrical surface or whose outer peripheral surface is spherical. When walking on the circumference, the cylindrical floating body rotates in synchronization with the movement of the human center of gravity. Due to this rotation, the blades 2, 4, 5.13 provided on the outer periphery or flange of the cylindrical floating body push the surrounding water in the direction opposite to the walking direction, and the reaction force causes the cylindrical floating body to move inside. It moves forward in the walking direction together with humans. Also, regarding the water walking and play equipment shown in Figure 1. As the forward walking speed increases, the water surface is pushed left and right by the forward movement of the cylindrical floating body 1, and water is prevented from penetrating into the interior of the cylindrical floating body 1. In addition, if these devices for water walking and play are walked while keeping the center of rotation parallel to the water surface, the cylindrical floating body can move straight because the left and right propulsion blades push the same amount of water backwards symmetrically. But. When a person moves slightly to the left or right to change the center of gravity, the cylindrical floating body tilts with respect to the water surface, causing a difference in the submerged area of the propulsion blades on the left and right sides. As a result, there is a difference in the propulsion force between the left and right sides, and the direction of movement of the cylindrical floating body changes to either the left or the right. Take advantage of this phenomenon. This equipment for walking and playing on water allows people walking on water to change their direction of travel at will, allowing them to reach their desired destination. In addition, by making the cylindrical floating body transparent or by providing a transparent window on the circumferential surface, it becomes possible to visually see the front and back in the direction of movement. In addition, this water walking and playing equipment can be used not only on water but also on land; for example, at the seaside, you can ride this water walking and playing equipment from the sandy beach. It is possible to set out on the sea as is, making it significantly more convenient than a regular boat. You can also use this equipment to train your sense of balance at a playground, or have fun competing for speed. However, when walking on land, when changing course to the left or right, the left and right direction of the center of gravity movement is opposite to that when walking on water. Also, when walking by holding on to the central shaft with a collar provided at the center of rotation of the cylindrical floating body, the posture is stable.
Easy to operate. In addition, the water that has entered the tubular floating body 3 through the discharge container 9 provided on the tubular floating body 3 shown in FIGS.
It is automatically released to the outside by the rotation of the . This discharge container 9 works when rotated in either direction, and if the cylindrical floating body 3 is tilted so that the side on which the discharge container 9 is provided is facing downward, the water discharge becomes more effective. Also, in Figure 4. When one side of the hole in the center of the flange is closed off with a lid 6, the lid 6 prevents water from entering. As shown in Fig. 11, the cylindrical floating body 3 can float on the water surface with its center of rotation perpendicular to the water surface, and in this state it can also enjoy fishing on the water. Furthermore, if both holes are closed, water will not enter the inside of the cylindrical floating body 3 no matter what position it is in. In addition, if these cylindrical floating bodies are made into a foldable bag shape as shown in Figure 9, they can be folded into a small size when not in use. When in use, it can be molded by compressing air inside, making it convenient to transport and store. Alternatively, as shown in Figure 10, if the cylindrical floating body is divided into parts so that it can be assembled and disassembled, transportation becomes easier. No. 1-1 of the attached drawings showing the embodiments of the present invention, etc.
A detailed explanation will be given based on Figure 1.

Figure 1 shows the basic structure of the water walking and play equipment according to the present invention, in which a cylindrical floating body 1 and propelling blades 2 are provided at both ends of its outer circumference, and inside the cylindrical floating body 1. When a person rides and walks, the center of gravity of the person moves forward, causing the cylindrical floating body 1 to rotate, and due to this rotation, the wings 1
2 pushes the water backwards. Due to the reaction force, the cylindrical floating body 1 can move forward while rotating with a person on board. At this time, if the human moves the center of gravity to the right, for example, in the direction of travel, the cylindrical floating body 1 will tilt to the right, and most of the left wing will be above the water surface, making it impossible to push the water backwards. On the other hand, the right wing is submerged deeper into the water, pushing more water backwards. Therefore, the propulsive force is greater on the right side, and the cylindrical floating body 1 moves to the left. Also, if the human center of gravity is shifted to the left, the opposite phenomenon will occur, and the cylindrical floating body 1 will move to the right. Furthermore, as shown in Fig. 2, the outer peripheral surface of this cylindrical floating body 1 is parallel to the center of rotation at the center, and both lateral surfaces are conical. When using this walking and play equipment on the ground, the cylindrical floating body 1 moves straight, to the right, and to the left by moving the center of gravity to the center, right, and left. The direction of travel can be controlled arbitrarily, allowing you to move towards your desired location. A similar effect can also be obtained when the outer peripheral surface is a single spherical surface. Also, if it is used only on the ground, propulsion blades are not required. Figure 3 shows a cylindrical floating body 3 with flanges integrally attached to both ends of the cylinder to prevent water from entering the inside of the cylinder. This is an equipment for walking and playing on water, which has propulsion wings 114 and 5 radially arranged on the flange with respect to the center of rotation. or. As shown in Fig. 4, the outer circumference of the cylindrical floating body 3 has a central part parallel to the center of rotation, and both lateral parts are conical, made of the same birch wood as in Fig. 2. A person can arbitrarily change the direction of travel by shifting the center of gravity to the left or right. Furthermore, by attaching the lid 6 to one or both holes in the center of the flange with bolts, etc., it is possible to completely prevent water from entering the interior. FIG. 5 is a side view of a device for walking and playing on water in which a central shaft 7 with a collar 8 is provided at the center of rotation of a cylindrical floating body 3. Figure 6 is its cross-sectional view. A person inside the cylindrical floating body can walk by holding on to this central shaft with a collar, and the human and the cylindrical floating body become one. It becomes possible to maintain a stable posture. FIG. 7 shows an apparatus for walking and playing on water in which a discharge container 9 is provided inside the flange portion of the cylindrical floating body 3 shown in FIG. It is. As shown in FIGS. 7 and 8, the discharge container 9 is disposed inside the flange all around the circumference. When the discharge container 9 is at the bottom, water that has entered the cylindrical floating body 3 enters the discharge container 9. As the discharge container 9 moves upward due to the rotation of the cylindrical floating body 3, the water held therein is automatically dropped and discharged to the outside of the cylindrical floating body 3 due to gravity. Figure 9 shows an equipment for walking and playing on water, which is formed into a cylindrical floating body 12 by pressurizing air into a foldable bag-like interior. and storage is convenient. In Figure 10, the cylindrical floating body 3 is divided into three parts. This is an equipment for walking and playing on water that can be disassembled and assembled using nuts 15. Figure 11 shows that I6 is installed in the center hole of one flange of the cylindrical floating body shown in Figure 4 to prevent water from entering. The center of rotation is perpendicular to the water surface. This is an example in which the center hole of the other flange is placed at the top so that people can enjoy fishing etc. through this top hole. Since the water walking and play equipment according to the present invention has the above-described structure and function, it is clear that it can exhibit the following effects. 1 A person rides inside a cylindrical floating body 1.3.12. By traveling inside the cylindrical floating body, the cylindrical floating body rotates due to the propulsive force generated by the propulsion vanes 2, 4, 5, and 13 provided on the outer circumferential surface. Humans can walk forward on water with a cylindrical floating body. 2. When a person inside a cylindrical floating body moves the center of gravity to the left or right and walks and rotates the cylindrical floating body while tilting it to the left or right, the propulsion blades act to arbitrarily change the direction of movement to the right or left. It can be changed and moved to the desired position. 3. This water walking and play equipment can also be used on the ground, but when used on the ground, it is installed on the outer circumferential surface of the cylindrical floating body. Due to the action of a surface parallel to the center of rotation of the cylindrical floating body and a conical surface provided on both sides of the surface. Or, because the outer circumferential surface is spherical, the person inside the cylindrical floating body moves his or her center of gravity from side to side. By tilting the cylindrical floating body from side to side, the direction of movement can be changed arbitrarily, and it can be moved to the desired position.

4. When walking or running on the inner circumferential surface of a cylindrical floating body while holding on to the central shaft with a collar provided at the center of rotation, the posture becomes stable and operation becomes easy.

5 Due to the action of the discharge container 9 provided inside the cylindrical floating body, water that has entered the inside is automatically discharged to the outside as the body rotates. 6. By closing the hole in the center of the flange of the cylindrical floating body with the lid 6. It can prevent water from entering the interior. Therefore. As shown in Figure 11, the center of rotation of the cylindrical floating body is perpendicular to the water surface, allowing you to enjoy fishing in a stable position. 7. The water walking and play equipment of the present invention is driven by human power. Unlike surfing, windsurfing, etc., it does not require the power of waves or wind, so it can be used as recreational or competitive equipment at the beach even on calm days with no wind or waves. 8. This equipment for walking and playing on water can be used not only on water but also on land, and can be used to train the legs and hips. Increased physical strength.
