In these figures, reference numeral 1 denotes a ski plate, and the ski plate 1 can be formed as a flat straight plate without an arc bend. This ski plate 1
Edges 2 are provided on both edges of the lower surface of the. On a top surface of a ski plate 1 according to this embodiment, a pair of arch plates 3.
3 are provided in parallel with elasticity, and shoe fasteners 5.5 are mounted on the arch plate 3.3.

A space is provided between the pair of arch plates 3.3.
The reinforcing portion 4 also serving as a support is provided as a single member or a separate member having a concave side surface and a curved surface. Both ends of the arch plates 3, 3 are fixed by inserting the shafts 6, 6 into the reinforcing portions 4, and a load when weight is put on the arch plates 3, 3, The arc plates 3, 3 are smoothly deformed and extended so that the ski plate 1 can be satisfactorily applied over a wide area.

In order to cope with the deformation of the arch plates 3, at least one of the fastenings of the arch plates 3, 3 is allowed to move by absorbing the pressure, and a roller is provided at the tip. A rolling or sliding member such as 7.7 is provided, and its rollers 7.7 are received by sliding members 8.8. Further, the part 4a of the reinforcing portion 4 on this side can be attached at a variable position so that the degree of bending of the arch plates 3, 3 can be adjusted in advance.

Also, the inner wall surfaces of the arch plates 3, 3 are provided with an arc which conforms to the side surface of the reinforcing portion 4, and the inner wall surfaces thereof are made of a flexible material such as a plastic or rubber plate. The scraping material 9 ・ 9 by is fixed,

Further, the above-mentioned arch plate 3 can be made as a single piece, and there is no transition of the fastening portions at both ends. At this time, the arch plate 3 is deformed at the time of pressurization as shown in FIG. 6, and the bottom surface of the ski plate 1 can be pressed against the snow surface with a stronger pressure. An angle is calculated in advance so that a right angle can be set sometimes.

When the arch plate 3 is made of one piece, the fixing of both ends is performed by supporting the support flanges 10 and 10 standing on the ski plate 1 with pins or the like. The pins are inserted into the support portions 11 to be engaged in a comb shape, and the ends of the arch plate 3 can be pivoted to absorb the deformation at the time of pressurization. The fasteners 5 are set so that the weight is placed on the top of the arch plate 3. When the pressure is applied to a wide area in the ski plate 1 having such a flat bottom surface, the sliding of the edge 2 with good effect can be obtained.

A ski plate can be used, and the best conditions can be created even with a dedicated ski plate for each eye. If the arch plate 3 is a bar and the fastening form is a sphere or the like at the end of the bar, the bar itself can be tilted at the time of turn or weight shift.
The operation can be easily performed.

Next, FIG. 9 shows a twin-chip type wake board 16 embodying the present invention, in which fins 17 are attached to the front and rear of the bottom surface so that the front and rear are the same shape so that fake can be slid with the same feeling. It is. The water surface is gliding by boats or marine jets, and at present, the large warp (rocker) of the board 16 is large so that it can be lifted up greatly when water hits the board 16. It is said. In the present embodiment, this board 16
A pair of arch plates 18 having the same shape are provided in tandem at appropriate intervals, and bindings 19 are provided on the arch plates 18. This binding 1
9 and 19 may be a strap or a high wrap, and the fastening structure of the arch plates 18 and 18 is the same as that of the ski plate 1 described above.

Further, the above-mentioned arch plates 18, 18 are connected to each other by a comb tooth engagement 11 or the like, and the outer end is fixedly engaged with the outermost end of the board 16 so that the entire length in the longitudinal direction is reduced. It is also possible to provide the arch plate 18 as a single piece at the front and rear ends of the board 16 with both ends pivotally fastened.

In this embodiment, if the arch plate 18 is divided vertically (FIG. 14),
8 to be weighted by the separation of
Will disperse the impact at the time of landing.

FIGS. 15 and 16 show the board 16 and the arch plate 18, both of which are divided in the longitudinal direction. The ends of the boards 16 and 21 are overlapped and connected by shafts 21.

It is an oval hole 45a. A cover plate 46 for covering the box portion 44 is fixed around the fins 43 by screws 47.
The insertion holes 7 and 47 are round at the rear end, and the other holes are oval holes 47a to cope with warpage.

The fulcrum mechanism 30 has generally triangular twin brackets 48, 48. Rotary rollers 49, 49 are pivotally supported at the tops between the brackets 48, 48. A pair of slide ridges 50 are integrally provided, and the slide ridges 50 are fitted into concave tracks 51 formed on the surface of the ski plate 16. And a pair of twin brackets 48
The adjustment bolt 52 is located in the middle of 48.

The lower end of the adjusting bolt 52 is provided with a bevel gear 5.
3, the bevel gear 53 is meshed with bevel gears 55, 55 coaxially opposed to a shaft 54 arranged in a direction orthogonal to the adjusting bolt 52. The meshing of the shaft 54 Is to be rotated. A different bevel gear 56 is provided at the end of the shaft 54.
56 is provided coaxially, and its rotational force is transmitted by meshing with the bevel gears 58, 58 at the lower ends of the working bolts 57, 57 located between the brackets 48, 48, and rotating the working bolts 57, 57. Becomes

The upper ends of the working bolts 57 are provided at the upper part of the bracket 48 by a rotating roller 49 which is in a state of being erected.
-Acts on the lower surface of the holding portion 48a of 49 and moves it up and down in the direction of rotation. By this operation, the height positions of the rotary rollers 49 as the fulcrum can be changed. In addition,
A guide ridge 48b is formed on the side wall surface of the holding portion 48a, and the guide ridge 48b is slidably contacted with the guide groove 48c to maintain the vertical direction.

On the other hand, the sliding position of the fulcrum mechanism 30 can be changed by sliding the whole while pressing the push buttons 59, 59 protruding from the outer surfaces of the outer end brackets 48, 48. One end of a locking rod 60 having a bifurcated tip and a substantially U-shaped side surface is screwed to the push button 59, and is pushed by a coil spring 61 elastically provided between the button flange 59 a and the inner wall surface.
9 is always energized outward. The inner wall surfaces of the concave orbits 51, 51 are provided with engaging holes 62, 6 at a pitch matching the stoppers 60a, 60a at the forked ends of the locking rod 60.
.. Are arranged side by side, and the stoppers 60a, 60a normally enter and lock the two adjacent ones of the engagement holes 62, 62.

When the push button 59 is pressed against the urging force of the coil spring 61, the locking rod 60 itself is pushed in, and the stoppers 60a
Since the fulcrum mechanism 30 is disengaged from 62 and becomes free, the fulcrum mechanism 30 is slid and shifted to an appropriate position, and the pressing on the push button 59 is released, whereby the lock at that position is obtained.

When the slalom ski having such a structure is used,
At the time of landing, the force from the pressure plate 27 acts, and the first and second lever bars 29 and 32 act to raise one end of the arch plate 33, thereby causing the tail portion of the ski plate 26 to rise. Warp,
The state is changed to the state shown in FIG. 37, and the performance and function can be freely adjusted by adjusting each fulcrum.
