Description

  The present invention relates to a water play equipment that is highly attractive as a marine sport and is easy to handle even for beginners.

  As water play equipment used for leisure, rowing boats, rowing boats, window surfing, yachts and the like are known.

  The rowing boat is a boat that advances the boat by rowing the oar-side oar by hand (for example, Patent Document 1). In the rowing boat, a cylindrical propulsion unit attached to the side surface or the rear side is rotated by pedaling, and is advanced by this.

  Rowing boats and rowing boats are operated while sitting on a boat, so the center of gravity is stable and anyone can easily handle them. However, rowing boats and toe-type boats repeat the bending and stretching movements of the limbs to advance the boats, so the movements are simple and lack attractiveness as marine sports.

On the other hand, yachts and window surfing are highly attractive as marine sports because they use the entire body to receive wind from the sail and advance on the surface of the water. However, yachts and window surfing are difficult for beginners to operate and are not easy for everyone to enjoy.

  Note that the distance from the connecting pin 141, which is the central axis of rotation, to the tips of the operation rods 111a, 111b is sufficiently longer than the distance from the connecting pin 141 to the connecting pins 142a, 142b. The propulsion plates 112a and 112b can be moved without applying a large force to the rods 111a and 111b.

  Next, the operation at the time of the game of the water play equipment 100 of the first embodiment of the present invention will be described.

  As described above with reference to FIG. 1, in the water toy equipment 100 according to the first embodiment of the present invention, when the operation bars 111a and 111b are tilted forward as indicated by the arrow A11, the propulsion plates 112a and 112b are indicated as indicated by the arrow A12. When the operating bars 111a and 111b are tilted rearward as indicated by an arrow B11, the propulsion plates 112a and 112b are rotated downward as indicated by an arrow B12.

  As shown in FIG. 4A, when the player 110 tilts the propulsion plates 112a and 112b in the direction of the arrow A11 and the propulsion plates 112a and 112b rotate in the direction of the arrow A12, a force F11 is generated on the water surface, and the surface is lifted. A force P11 is generated such that the front side of the body 101 is raised and the rear side is lowered. Further, as shown in FIG. 4B, when the player 110 tilts the operation rods 111a and 111b in the direction of arrow B11 and the propulsion plates 112a and 112b rotate in the direction of arrow B12, a force F21 is generated on the water surface. A force P21 is generated such that the rear side of the floating body 101 is raised and the front side is lowered.

  The player 110 stands on the floating body 101, grasps the operation rods 111a and 111b with both hands, moves the operation rods 111a and 111b while moving the weight back and forth, and rotates the propulsion plates 112a and 112b up and down. By moving it, the levitated body 101 can be advanced, pitched, yawed, or rolled for enjoyment. In the water toy equipment 100 according to the first embodiment of the present invention, the player 110 stands and operates on the floating body 101, so that it is easy to shift weight and balance.

  Further, when the water play equipment 100 according to the first embodiment of the present invention is advanced, the levitating body 101 can be advanced by swinging the propulsion plates 112a and 112b up and down like a dolphin swims. it can.

  That is, when the water play equipment 100 according to the first embodiment of the present invention is advanced as if a dolphin swims, the player 110 is straight on the floating body 101 as shown in FIG. Then, the operating rods 111a and 111b are tilted in the direction of the arrow A11. When the operation bars 111a and 111b are tilted in the direction of arrow A11, as shown in FIG. 5B, the weight is applied to the front side, and the propulsion plates 112a and 112b rotate in the direction of arrow A12.

  Next, as shown in FIG. 5C, the player 110 tilts the operation bars 111a and 111b in the direction of arrow B11. When the player 110 tilts the operation rods 111a and 111b in the direction of arrow B11, the weight is applied to the rear side, and the propulsion plates 112a and 112b rotate in the direction of arrow B12, resulting in the state shown in FIG.

  Next, as shown in FIG. 5E, the player 110 tilts the body forward, and tilts the operation bars 111a and 111b in the direction of the arrow A11. When the operation rods 111a and 111b are tilted in the direction of arrow A11, the weight is applied to the front side, and the propulsion plates 112a and 112b rotate in the direction of arrow A12 as shown in FIG.

  Hereinafter, when the player 110 tilts the operation rods 111a and 111b in the directions of the arrow A11 and the arrow B11, the propulsion plates 112a and 112b swing up and down as indicated by the arrows A12 and B12, and float by the water flow. The body 101 moves forward.

  Here, in the water toy equipment 100 according to the first embodiment of the present invention, as described above, when the player 110 tilts the operation bars 111a and 111b to the front side (A11 direction), the propulsion plates 112a and 112b are on the upper side (A12 direction). ) And the player 110 tilts the operation bars 111a and 111b rearward (B11 direction), the propulsion plates 112a and 112b rotate downward (B12 direction). For this reason, when the propulsion plates 112a and 112b are swung up and down, useless movement of the levitated body 101 can be suppressed.

  That is, when the player 110 tilts the operation rods 111a and 111b in the direction of arrow A11 and the propulsion plates 112a and 112b rotate in the direction of arrow A12, as shown in FIG. Is generated, and a force P11 for lowering the rear side is generated. However, in the water toy equipment 100 according to the first embodiment of the present invention, at this time, the player 110 falls the operation bars 111a and 111b in the direction of the arrow A11, so that the weight is applied to the front side and the front side of the floating body 101 is lowered. Such a force Q11 is generated. The force P11 is canceled by the force Q11, and it is possible to suppress the useless movement that raises the front side of the levitated body 101.

  Similarly, when the player 110 tilts the operation rods 111a and 111b in the direction of arrow B11 and the propulsion plates 112a and 112b are rotated in the direction of arrow B12, as shown in FIG. A force P21 is generated to raise the rear side and lower the front side. However, in the water toy equipment 100 of the first embodiment of the present invention, the player 110 tilts the operation bars 111a and 111b in the direction of the arrow B11 at this time, so that the weight is applied to the rear side, and the rear side of the floating body 101 A force Q21 is generated that lowers. The force P21 is canceled by the force Q21, and it is possible to suppress the useless movement that raises the rear side of the floating body 101.

  As shown in FIG. 5, in the first embodiment of the present invention, the levitating body 101 can be moved forward by swinging up and down the propulsion plates 112 a and 112 b at the same time as when a dolphin swims. At this time, the water play equipment 100 according to the first embodiment of the present invention can exert a strong driving force based on ergonomics.

  That is, when the player 110 operates the operation rods 111a and 111b, it is difficult to put the weight on the player 110 while sitting, so the muscle exercise is performed using the upper arm of the player 110. This places a heavy burden on the player 110 and it is difficult to obtain a large driving force.

  On the other hand, in the water toy equipment 100 according to the first embodiment of the present invention, the operation bars 111a and 111b are operated by the player 110 falling down from the standing state. The action of the player 110 falling down uses the weight of the player 110 as potential energy, and therefore becomes a great driving force without placing a burden on the player 110.

  In particular, the action of falling backward is the action that most easily puts the entire weight on ergonomics, such as when performing a tug of war competition.

  In the water toy equipment 100 according to the first embodiment of the present invention, as shown in FIGS. 5C to 5D, the player 110 drops the operation bars 111a and 111b in the direction of the arrow B11, and the propulsion plate 112a. And the movement when 112b rotates in the direction of arrow B12 is a movement in which a person falls backward, and at this time, a large driving force is obtained.

  In addition, as described above, the water toy device 100 according to the first embodiment of the present invention not only performs the operation of simulating the swimming of dolphins, but also alternately pushes the propulsion plates 112a and 112b like a crawl foot. The levitated body 101 can also be moved forward by operating it to move back and forth.

  Further, the floating body 101 can be more actively propelled by shifting the weight of the player 110 and pitching, yawing, and rolling using the movement of the propulsion plates 112a and 112b.

  Further, in the water toy equipment 100 of the first embodiment of the present invention, the propulsion plates 112a and 112b are provided independently on the left and right, and the left and right propulsion plates 112a and 112b are provided by the left and right operation rods 111a and 111b, respectively. Can be operated independently. For this reason, it is possible to roll the levitating body 101 and change its direction or to balance left and right by independent operation of the left and right propulsion plates 112a and 112b.

  In the water toy equipment 100 according to the first embodiment of the present invention, various movements are possible in response to various operations of the player 110 as described above.

  As described above, in the first embodiment of the present invention, since the whole body is actively used for operation, it is highly attractive as a marine sport and can be easily operated by beginners.
