[Action]
In the case of skiing practice, the trainer T firstly skies the first slope 2 made of a high friction material such as a rubber and / or elastomer sheet, a fiber knitted fabric or a cork board of the downhill training tool 21 on the ski or ski boot B. Wear a pair of practice footwear with a short board S fixed and walk down. During that time, the correct downhill posture can be obtained naturally. Next, the practitioner moves to the second slope 3 made of a raised sheet. The second slope 3 is made of a medium friction material such as artificial turf or carpet, and has a slightly lower coefficient of friction than the first slope 2. The practitioner can maintain the correct posture obtained on the first slope 2 and can descend at low speed without fear. The third slope 4 is made of a low-friction material such as a polypropylene sheet or a polyethylene sheet, and has a lower friction coefficient than the second slope 3, but has a higher friction coefficient than the snow surface. , The practitioner is not afraid and can maintain the correct posture and run down. Therefore, even if it moves to the snow surface after the 3rd slope 4, the practitioner can maintain downhill in the correct posture.

  In order to prevent the fear of the practitioner and to make it easy to take a correct downhill posture, the inclination angle of the first slope 2 is 5 ° to 30 °, and the inclination of the second slope 3 and the third slope 4 is. The angle is preferably set in the range of 5 ° to 15 °. And in the 1st slope 2, it is desirable to be able to adjust inclination-angle in the range of 5 degrees-30 degrees, in order to make a practitioner take the correct downhill posture.

  The downhill practice table 1 is installed at a predetermined location on the slope 5, and a practitioner who has acquired a correct downhill posture on the downhill practice table 1 moves to the snow surface of the slope 5 and slides down the slope. When the touch tool 6 is installed at a predetermined position 5, the trainee T slides down the slope 5 and tries to touch the touch tool 6. Then, the trainee T can acquire the correct rotation posture by naturally tilting the body to the right or left in order to move toward the installation position of the touch tool 6. In addition, since the body bends and stretches when trying to touch the touch tool 6, the undulation of the slope 5 can be handled.

  When the grip 64E is attached to both ends of the rotating rod 63E that rotates horizontally as the touch means of the touch tool 6, the practitioner T grabs or holds the grip 64E of the rotating rod 63E while sliding down. If so, the body also rotates at a large angle of 90 ° to 180 ° by the rotation of the rotating rod 63E.

  If a plurality of such touch devices 6 are arranged on the slope 5 in a zigzag shape, the practitioner will naturally move from the right tilt position to the left tilt position and from the left tilt position to the right tilt position, trying to make a left turn while sliding down. To practice.

  When a brake tool 8 made of a cylindrical or columnar friction material is installed in a predetermined position on the slope 5 in a pair of left and right C-shapes, the trainer T is in the middle of the pair of left and right brake tools 8 installed in a C-shape. When skiing down, the ski S collides with the braking device 8 and opens in the shape of a letter C, so that the entire braking force is naturally acquired.

  A direction change training tool 9 having a shape in which a cone is cut out is installed at a predetermined position on the slope 5. In this case, it is usually installed so that the cone axis is perpendicular to the slope of the slope 5. Then, the trainer T who has come down the slope rides on the direction change exercise tool 9 and is guided by the surface shape of the exercise tool 9 so that it naturally turns right or left. To practice.

  A ridge-shaped pulque practicing tool 10 having an isosceles triangle cross section is installed at a predetermined location on the slope 5 with a length of 3 to 10 m. In this case, it is usually installed so that the pluck training device 10 extends along the slope of the slope 5. Then, the trainer T who has come down the slope rides on the pluck training tool 10 and is guided by the slope shape on the surface of the training tool 10 to naturally open the ski S into a C-shape. It becomes the practice of mastering the pluke posture that opens in the shape of C.

〔effect〕
When the downhill practice table 1 of the present invention is used, the practitioner can descend the snow surface in a correct posture without fear.
In addition, by sliding down while touching the touch tool 6, the rotation technique can be naturally enjoyed and the rotation technique can be acquired, and the direction change training tool 9 can be used to change the direction with knee flexion and extension. At 10, the prok posture that opens the ski S in a C-shape is acquired.
Furthermore, if the brake tool 8 is used, the whole braking technique can be naturally acquired.
Therefore, according to the present invention, downhill techniques such as straight downhill, rotation, direction change, undulation downhill, and full braking can be learned happily.

The present invention will be specifically described below with reference to the embodiments shown in FIGS.
FIG. 1 shows a downhill practice table 1. The downhill practice table 1 has a substantially right triangle shape in a side view, and the upper surface is divided into three slopes: a first slope 2, a second slope 3, and a third slope 4. The first slope 2 is made of a high friction material that allows a practitioner wearing a ski to walk without slipping. The high friction material is made of a high friction material such as a rubber or elastomer sheet, a fiber knitted fabric, or a cork board. The rubber or elastomer sheet surface may be grained. The second slope 3 is made of a medium friction material that allows the practitioner to slide down at low speed without fear. Examples of the medium friction material include fiber sheets such as artificial grass, cloth, and flocked cloth (flocked carpet), or the surface of a substrate. A sheet provided with a flexible pile layer is used. Examples of the medium friction material include an artificial lawn disclosed in Japanese Patent No. 3734565, a sliding mat disclosed in Japanese Patent Laid-Open No. 10-146415, and the surface friction amount is a skid resistance value obtained by a skid resistance test. Is preferably 10 or less. The third slope 4 is made of a low friction member that can be safely slipped by the practitioner, that is, slightly slippery than the snow surface. Examples of the low friction material include a polyethylene sheet, a polypropylene sheet, and an ethylene-vinyl acetate copolymer sheet. A low friction material having a dynamic friction coefficient in the range of 0.1 to 0.3 determined by a method multiplied by JISK7125 is used.

The said 1st slope 2 is supported as an inclined surface on the support means 22 of the downhill practice tool 21 as shown, for example in FIGS. The support means 22 is, for example, four jacks 22A, 22A, 22B, and 22B that support the left and right of the front end and the rear end of the slope 2. By using the support means 22 as a jack as described above, the angle of the first slope 2 can be adjusted. In general, the angle of the first slope 2 is set in a range of 0 to 40 °. Note that the support means 22 is not limited to a jack, but may be changed to a hydraulic, pneumatic or hydraulic cylinder, a column or bar whose length can be changed, and a spring so that the angle of the first slope 2 can be adjusted.
As shown in FIG. 4, two jacks 22 </ b> A and 22 </ b> B as the support means 22 may be attached to the front end and the rear end of the first slope 2, one by one.
Further, as shown in FIG. 1, a first slope having a predetermined angle in a range of 0 to 40 ° is provided on a support base 22 having an inclined surface as a support means without attaching an angle adjusting means such as a jack. 2 may be provided.
The downhill practice tool 21 may be used independently of the second slope and the third slope. In that case, the practitioner T puts on the ski S or puts on the footwear B for practice with a strip-shaped base attached to the lower surface of the boot as shown in FIG. 3, and faces downward or upward as shown by the arrow in FIG. Practice forward or backward. In addition, the angle of the first slope 2 is gradually steeply inclined to the limit of 40 ° so as to get used to the steep slope. In this way, the trainer T gets used to the steep slope, the fear of the steep slope is removed, and the correct downhill posture, balance, and trunk L can be easily obtained. Specifically, the practitioner T walks so that the trunk L is perpendicular to the slope 2 (see FIG. 2).

  The downhill practice platform 1 is set at a predetermined location of, for example, a snowy slope or an artificial slope in which a downhill mat provided with a pile layer on the surface of the base material is laid. The practitioner T first walks on the first slope 2 wearing skis from above. In the meantime, the practitioner can acquire a stable forward leaning posture suitable for downhill. When using the first adjustable slope 2 shown in FIG. 2, the practitioner walks with the core axis L perpendicular to the slope 2, and with respect to the slopes of various angles, It will be practice to take the right downhill posture. Since the first slope 2 does not slide on the practice platform 1, even if it is steep, it can take a forward leaning posture without fear. Usually, if the slope becomes steep on the snow surface, the practitioner will take a back leaning posture from fear and cannot learn the correct downhill posture.

  Once you have acquired the correct downhill posture on the first slope 2, you move to the second slope 3 and attempt a low-speed downhill. In this case, if it is low-speed downhill, the correct downhill posture acquired on the first slope 2 can be maintained without fear.

  The third slope 4 is even faster downhill, but the downhill speed does not suddenly increase, but gradually increases from the first slope 2 → the second slope 3 → the third slope 4 so that the practitioner is completely terrified. It is possible to increase the downhill speed with a correct posture without a heart.

Once you have learned the correct posture by downhill at a certain speed in this way, you can finally move to the slope and downhill at normal speed.
On the slope 5, for example, as shown in FIGS. 5A and 5B, touch tools 6A are arranged in a zigzag manner. The touch tool 6A has a structure in which a grip ring 62A is pivotally attached as a touch means to the apex of a bowl-shaped base 61A. The height h of the upper end of the grip ring 62A is determined from the position of the waist of the practitioner or the waist. Make it a little lower.

  As shown in FIGS. 3A and 3B, the trainee T slides down and grips the grip ring 62A of the touch tool 6A to the left and to the right. Thus, the practitioner learns the rotation with left-right weight shift, which is the basis of Christiania and Wedeln. In addition, it becomes possible to cope with undulation of the slope by bending and stretching the knee.

  As shown in FIG. 6, the touch tool 6B may have a configuration in which a bell 63B as a sound output device having a button 62B as a touch means is attached to the apex of a conical base 61B.
