A pair of cutouts 14a, 14a are formed at the ends of the shaft support band 14, and tightening bands 15 are attached to both ends where the cutouts 14a are formed.
The tightening band 15 is configured so that the tightening force on the shaft support band 14 can be increased or decreased by rotating the tightening lever 16.

When the tightening lever 16 is rotated to increase the tightening force with respect to the shaft support band 14, the angle of the front leg portion 2 with respect to the bottom plate 1 is maintained and it becomes impossible to rotate. When the tightening lever 16 is rotated in the opposite direction to weaken the tightening force on the shaft support band 14, the front leg 2 becomes rotatable and the angle with respect to the bottom plate 1 can be freely changed.

FIG. 4 shows a brake portion provided on the rear side of the rear leg portion 3. A brake pipe 36 is fixed to the rear peripheral surface of the damper portion 32, and a brake shaft 37 is slidably arranged on the brake pipe 36. This brake shaft 3
One end of a connecting link 40 is rotatably supported at the upper end of 7, and the other end of the connecting link 40 is at one end 39 of the lever 39.
It is pivotally supported by b.

The lever 39 is rotatably supported on the connecting shaft 38 at its central portion 39a. The other end 39c of the lever 39 is connected to the brake wire 27, and by gripping the brake lever 26, the other end 39c is rotated upward. When the other end 39c is rotated upward, one end 39 of the lever 39 is pivoted about the central part 39a.
b is lowered, and accordingly, the brake shaft 37 is also lowered via the connecting link 40.

At the lower end of the brake shaft 37, there is provided an end surface 37a which is substantially parallel to the sliding surface on the back surface of the bottom plate 1.
Is moved down as described above, the end surface 37a becomes the brake pipe 3
It projects from the opening at the lower end of 6 to below the gliding surface (see the chain line in the figure) and bites into the snow surface to perform a braking action.

The fixing member 18 is fixed on the surface of the bottom plate 1 and pivotally supports the hinge shaft 31 to rotatably mount the damper portion 32 on the bottom plate 1.

In the above-described embodiment, since the motorcycle structure having the handle is formed on the bottom plate on the snowboard, even if the motorcycle has only a single running surface, the handle or the saddle may be used. The intention of the user can be accurately transmitted to the bottom plate 1, and since the weight of the user is supported by the presence of the handle and the saddle, the movement of the center of gravity of the user can be easily corrected. The operability can be greatly improved.

Since the front leg portion 2 and the rear leg portion 3 are rotatably connected to the bottom plate 1, the load applied to this connecting portion is relieved and accidents such as damage to the connecting portion are prevented. You can The reason why this is important is that damage to these connections requires replacement of the bottom plate 1 and is therefore more damaging than damage to the connections between the front and rear legs 2 and 3 and the connecting shaft 4. This is because it becomes larger. In this case, by inserting a rubber bush or the like in the connecting portion between the connecting shaft 4 and the front leg portion 2 or the rear leg portion 3, the flexibility of the connecting portion is secured and the stress applied to the connecting portion is secured. It can also be reduced. The reduction of these stresses is also achieved by the presence of the damper part.

In the present embodiment, since the brake is formed by the brake shaft that appears and retracts along the rear leg, both the improvement of the strength of the brake and the simplification of the brake structure have been successfully achieved. Further, by providing the brake at the rear part, it is possible to obtain a stable braking effect. The brake provided on the rear part can stabilize the directionality during braking and also ensure the stability in the front-rear direction. Furthermore, the operation in coordination with the movement of the weight enables a tricky operation like a wheelie. . At this time, since the tail portion 1b is formed at the rear end of the bottom plate 1, even if the tail plate 1b is slightly tilted rearward due to an operation of a wheelie or the like, the fall is prevented.

Since the left and right brakes are operated independently of each other, for example, the course can be changed by operating only one of them, or the trigger of the turn can be triggered by temporarily applying one brake before the turn. You can

Since the front and rear legs and the connecting shaft are detachably attached, they can be easily stored and carried, and by removing the connecting shaft, they can be freely rotated. The attached front leg and rear leg can be laid down and can be stored compactly. In addition, by fixing the rear legs in a lying state and further fixing the connecting shaft on this, you can glide only by grasping the handle of the front leg or you can easily get on the lift with the handle grasped. It becomes possible.

Further, since the angle of the front leg with respect to the bottom plate can be fixed, the operability when sliding using only the handle is further improved, and the snow bike is more comfortable to carry when riding on the lift. .

In the above embodiment, any other known method may be adopted for the rotatable mounting structure of the bottom plate and the front and rear legs and the mounting structure of the front and rear legs and the connecting shaft. You can Further, the damper parts of the front leg part and the rear leg part may not be provided if not necessary. The front leg and the rear leg are each provided with a pair of shaft legs, but one may be provided as long as sufficient strength can be secured.

[0050]

As described above, according to the present invention,
Although it is a gliding tool with a single gliding surface, it can accurately convey the intention of the user to the bottom plate, and since the presence of the handle and saddle supports the weight of the user, Since the movement of the center of gravity can be easily corrected, it is possible to realize a new leisure tool which can greatly improve the operability.
