The rotation angle of 12b varies depending on the magnitude of the load applied to the pedals 14a and 14b. If a large load is applied to the pedals 14a and 14b, the movable fins 12a and 12b move largely downward, and when the load applied to the pedals 14a and 14b is small, the descending amount of the movable fins 12a and 12b becomes small.

As shown in FIG. 4 (a), the movable fins 12a,
With the 12b in the upper position, the movable fins 12a, 12
The flow of the river hardly acts on b, and thus the propulsive force acting on the board is small. On the contrary,
As shown in FIG. 4B, when the movable fins 12a and 12b are both lowered to the lower position, the flow force is the largest and acts on the movable fins 12a and 12b. As a result, the board will progress the fastest. In addition, as shown in FIG.
In the state in which one of 2a and 12b is lowered, the flow advances on the lowered movable fin, so that the board advances in a curved manner. The state of FIG. 5 (a) is a state in which the board curves leftward with respect to the traveling direction,
The state (b) corresponds to a state in which the board curves to the right with respect to the traveling direction.

As described above, in the sports board according to the present invention, the load applied to the pedals 14a and 14b is changed to adjust the speed of the board and operate the traveling direction of the board to operate the board. It becomes possible to go down the river. The movable fins 12a and 12b easily move up and down depending on how the load is applied to the pedals 14a and 14b. By operating the pedals 14a and 14b while balancing the body on the board, an operation with a very sporty feel can be achieved. It will be possible.

The sports board of the above-mentioned embodiment is an integral type in which the left and right foot plates 16a and 16b are installed on the board body 10, but as shown in FIG. The board body 10a and the board body 10b for the right foot may be used in a pair. Each board body 10a, 10b is provided with a movable fin 12a for the left and a movable fin 12b for the right,
As an operating mechanism for rotating (moving up and down) the movable fins 12a and 12b, the pedals 14a and 14b provided on the foot plates 16a and 16b and the movable fins 12a and 12b are connected by a wire 28 to apply a load to the pedals 14a and 14b. It is similar to the above-described embodiment that the movable fins 12a and 12b are provided with a structure to rotate the movable fins 12a and 12b.

According to the sports board of this embodiment, the degree of freedom in operating the left and right board bodies 10a, 10b is increased, and the pedals 14a, 1b of the board bodies 10a, 10b are increased.
It is possible to greatly change the load acting on 4b as compared with the integrated type. As a result, it becomes possible to further enhance the sportiness as compared with the case of using the integrated board body. However, when the left and right boards are made independent, the stability decreases, so to compensate for the stability, when the inner surfaces of the left and right board bodies 10a, 10b are aligned, a certain degree of positional deviation is allowed. It can be locked relative to each other or can be used as a float stock to balance the body.

FIG. 7 shows an example of the structure of the floating wheel stock. The floating wheel stock 50 shown in FIG. 7A has a grip portion 53 provided on an upper portion of a pole 52, and a spherical float 54 is attached to a lower end portion of the pole 52. FIG. 7B shows an example in which an ellipsoidal float 55 is provided instead of the spherical float 54. Further, FIG. 7 (c) shows that the float 56 is formed into a spherical shape in which fins are combined with each other, and buoyancy and the fining effect of the web are imparted. In the case of the floating wheel stock 50 shown in FIGS. 7 (a) and 7 (b), the floats 54 and 55 may be provided with separate fins for webbing.

In both the case of the board shown in FIG. 1 and the case of the board shown in FIG.
Stand up and operate the board. The state of the water flow in the river changes greatly, and it is easy to lose physical balance. In such cases, a float stock 50 such as that shown in FIG. 7 may be used to balance the body. When using a board to slalom in a river with a stream of water, use a freehand method without using the float ring stock 50, or use the float ring stock 50. It is possible to use methods such as operating while balancing the body.

The sports board according to the present invention can be used in various situations such as a place where the flow is strong or a place where the flow is weak. Also, the trend is intense,
When the movable fins 12a and 12b are likely to hit rocks, it is preferable to use the movable fins 12a and 12b made of a soft material so that the movable fins 12a and 12b are not broken by impact even when they hit rocks or the like.

In each of the above-described embodiments, the movable fins 12a and 12b are attached to the flat board body 10.
Although the board body 10 is formed in a boat shape, the left and right movable fins 12a and 12b are attached to the tail of the ship in the same manner as described above, and the pedals 14a and 14 are attached.
It is also possible to move the movable fins 12a and 12b by the operation of b to adjust the propulsive force of the board or adjust the traveling direction of the boat. In the case where the boat is formed in this way, one or a plurality of people can be placed in the board body 10 and the boat can be operated by operating the pedal.

[0031]

According to the sports board of the present invention,
As described above, the movable fins can be rotated in the vertical direction only by operating the pedals, and thus the traveling direction of the board that is advanced by the water flow can be controlled.
By controlling the load applied to the pedal with the heel and operating the movable fins, it is possible to control the board according to the flow of water such as a river, and a sports board that can be used in new ways such as manipulating the board according to the flow Can be provided as.
