  In many cases, advanced skiers use this type of training device for the purpose of making a form for quick slipping or correcting the form. Therefore, in particular, the turn operation and the operation of switching the direction of the turn are important, and it is required to reproduce a situation close to actually falling down the snow surface.

  However, the ski training device of Patent Document 1 has a structure in which the footrest swings and tilts like a seesaw around the rotation axis, and the training machine of Patent Document 2 has a support base on the curved surface of the slide bearing. In any case, when turning, the sense that “the edge of the ski is standing on the snow surface” cannot be obtained.

  Further, in the case of the ski practice device of Patent Document 1, force from the restoring force generating means is always applied to the footrest (the moment when the footrest passes through the center position of the rail is not biased). Therefore, it is difficult to reproduce the feeling of exaggeration that “the force (reaction force) from the snow surface to the ski is reduced for a short time to switch the posture” when the operation of switching the direction of the turn is performed. In the case of the training machine of Patent Document 2, this problem cannot be solved sufficiently.

  The present invention has been made in view of the above-described background art, and provides a training apparatus for snow-sliding sports having a simple configuration capable of realizing a training environment in which a snow surface is actually slid down. The purpose is to do.

  The present invention has a moving body attached to a base and movable in the left-right direction with respect to the base, and the moving body supports a fixing member to which a user's foot is fixed, and the fixing member. A footrest comprising a support, and the base is provided with a leftward biasing member that biases the movable body leftward and a rightward biasing member that biases the movable body rightward. The support is provided with a hinge that allows the right side to be lifted about the left side of the fixing member when a force to tilt the fixing member to the left side is applied, and a right side with respect to the fixing member. When a force to incline is applied, the training apparatus for snow-sliding sports, comprising: another hinge that enables the left side to rise with the right side of the fixing member as an axis.

  The support includes a swinging member that is swingable with respect to the moving body, and the swinging member is provided with one end portion swingable with respect to the moving body via a first hinge. The other end portion supports the fixing member in a swingable manner via the second hinge.

  It is used for training on snowy skiing by skiing, and two sets of the moving body and the footrest are provided independently. The left footrest is provided with a shoe fixing device for the left foot, and the right foot. On the platform, a shoe fixing tool for the right foot is attached.

  Alternatively, it is used for snowboarding training with a snowboard, and a set of the moving body and the footrest is provided, and a shoe fixing device for a user's right foot and left foot is attached to the footrest. Is.

  The training apparatus for snow-sliding sports of the present invention can perform training with a motion close to the actual turn motion in the training of the turn motion by the support member that supports the user's foot. Furthermore, by appropriately adjusting the distance that the moving body can move and the urging force by the right and left urging springs, it is possible to freely create a training environment suitable for each person's technical ability from beginner to advanced. .

  Hereinafter, a first embodiment of a training apparatus for snow sliding sport according to the present invention will be described with reference to FIGS. As shown in FIG. 1, the training device 16 of the first embodiment is a device that is used for training on snow skiing by skiing.

  As illustrated in FIG. 2, the training device 16 includes a base 18, a first moving body 20, a second moving body 22, and a footrest 24. As shown in FIG. 3, the base 18 includes a pair of two linear guides 30 formed by attaching two sliders 28 a and 28 b to the rail 26. The sliders 28a and 28b can reciprocate on the rail 26 with low friction. The pair of linear guides 30 are parallel to each other with the rails 26 connected by a connecting frame 32, and are supported substantially horizontally by legs 33 provided on each rail 26. Hereinafter, in the state where the base 18 is installed, the longitudinal direction of the rail 26 is referred to as the left-right direction, and the direction in which the two rails 26 face each other is referred to as the front-rear direction.

  Further, a shaft 34 that is long in the left-right direction in FIG. 3 is attached to the base 18 between a pair of rails 26, and a leftward biasing spring 36 and a rightward biasing spring 38 are provided outside the shaft 34. Yes. The length of the shaft 34 is substantially the same as that of the rail 26.

  The leftward biasing spring 36 is composed of three coil springs 40 (40 (1), 40 (2), 40 (3)) having different spring constants, inserted in series in the shaft 34, and each coil spring 40 is in a uniform direction. It has a structure that expands and contracts in the (left-right direction). Here, the spring constant of the coil spring 40 (1) is the smallest, and the spring constant of the coil spring 40 (3) is the largest. The right end portion 36a of the leftward biasing spring 36 is held by a plate-like right end holding portion 42a fixed to one end of the shaft 34, and the opposite left end portion 36b is a biasing spring pressing force of the first moving body 20 described later. It is in contact with the portion 44. In addition, a partition plate 45 that is movable in the left-right direction is placed between adjacent coil springs 40 and sandwiched. The leftward biasing spring 36 functions to bias the first moving body 20 leftward (toward the center position of the rail 26).

  The rightward biasing spring 38 is composed of three coil springs 40 (40 (1), 40 (2), and 40 (3)), similar to the leftward biasing spring 36, and is inserted into the shaft 34 in series. Each coil spring 40 has a structure that expands and contracts in a uniform direction (left-right direction). The left end portion 38b of the rightward biasing spring 38 is held by a plate-like left end holding portion 42b fixed to the other end of the shaft 34, and the opposite right end portion 38a is a biasing spring of the first moving body 20 described later. It is in contact with the pressing portion 44. Further, a partition plate 45 is inserted between the adjacent coil springs 40 in the same manner as described above. The rightward biasing spring 38 functions to bias the first moving body 20 rightward (toward the center position of the rail 26).

  As shown in FIG. 4, the first moving body 20 includes a pair of two linear guides 50 in which two sliders 48 a and 48 b are attached to a rail 46. The rail 46 is shorter than the rail 26 of the base 18, and the sliders 48a and 48b can reciprocate on the rail 46 with low friction. The pair of linear guides 50 are parallel to each other with the rails 46 connected to each other by a biasing spring pressing portion 44. The biasing spring pressing portion 44 is a slightly bent frame, and a shaft insertion hole 44a through which the shaft 34 can be inserted with a space is formed at the center. Moreover, stoppers 52a and 52b are attached to the left and right ends of the rail 46, and when the second moving body 22 to be described later comes into contact, it is restricted so that it cannot move any further.

  As shown in FIG. 2, the first moving body 20 has a shaft 34 inserted inside a shaft insertion hole 44 a of the urging spring pressing portion 44, and a peripheral portion of the shaft insertion hole 44 a is a left end portion of the leftward urging spring 36. 36b and the right end portion 38a of the rightward biasing spring 38 are brought into contact with each other. A pair of rails 46 are arranged in a direction parallel to the rails 26 of the base 18, are attached to the upper surfaces of the sliders 28a and 28b, and are supported substantially horizontally. Therefore, the first moving body 20 is movable in the left-right direction. When the first moving body 20 moves from the center position of the rail 26 to the right side, the left-side biasing spring 36 is pushed by the biasing spring pressing portion 44. The first moving body 20 is urged to the left by contracting. Similarly, when the first moving body 20 moves from the center position of the rail 26 to the left side, the rightward biasing spring 38 is pushed by the biasing spring pressing portion 44 and contracts, and the first moving body 20 is biased rightward.

  The second moving body 22 is a plate material on which the footrest 24 is fixed on the upper surface. Two footrests 24 are attached to the second moving body 22, and one foot (a foot wearing ski boots) is supported by the two footrests 24 as shown in FIG. 5. The footrest 24 includes a thin, thin rectangular fixing member 56 to which a shoe fixing device 54 is attached, and a support member that supports the fixing member 56 and fixes it on the second moving body 20. . The width dimension of the fixing member 56 is set to the actual width dimension of the ski. The support includes a swing member 58 that is swingably provided, and a lower plate 60 on which the swing member 58 is provided. One end portions in the width direction of the swing member 58 and the lower plate 60 are rotatably connected via the first hinge 62, and the other end portions in the width direction of the swing member 58 and the fixing member 56 are connected to the second hinge. The lower plate 60 is fixed to the upper surface of the second moving body 22. The two footrests 24 are arranged on the second moving body 22 side by side in the front-rear direction of the body, one shoe fixing device 54 fixes the toe portion, and the other shoe fixing device 54 fixes the heel portion. The second hinges 62 and 64 are located on the outer side and the inner side of the ski boot, respectively. Usually, since the bottom surface of the ski boot is hard and flat, the two fixing members 56 are flush with each other when the ski shoe is fixed.

  As shown in FIG. 2, two sets of the second moving body 22 and the footrest 24 are provided for the right foot and the left foot, and the second moving body 22 for the right foot is used for the sliders 48 a and 48 a of the first moving body 20. The second moving body 22 for the left foot attached to the upper surface is attached to the upper surfaces of the sliders 48b and 48b of the first moving body 20, so that it can move independently in the left-right direction. Here, in order to perform training with the content of “wearing a form in which the left foot and the right foot are not too close at the time of turn”, as shown in FIG. Connected at 65. The connecting spring 65 may be omitted if not necessary, for example, when used by an advanced user. The left and right end positions to which the second moving body 22 moves are defined by the stoppers 52a and 52b. That is, the second moving body 22 can move in an inner range that does not contact the stoppers 52a and 52b.

  When the support (the swinging member 58, the lower plate 60, the first hinge 62, and the second hinge 64) of the footrest 24 is applied with a force to tilt the fixing member 56 to the left, FIG. As shown in (a), the right end is raised about the second hinge 64 at the left end of the fixing member 56 as an axis. On the other hand, when a force to tilt the fixing member 56 to the right side is applied, the fixing member 56 is moved by the first hinge 62 at the right end of the swinging member 58 as shown in FIG. The left end is raised with the right end of the shaft as an axis. Therefore, the height of the lowest portion of the fixing member 56 is substantially constant even when the tilting direction or angle changes.

  Next, the operation of the training device 16 will be described. In the initial state of the training device 16, as shown in FIG. 2, the first moving body 20 is stationary at the center position of the rail 26 by the biasing from the leftward and rightward biasing springs 36 and 38. A user wearing ski boots first fixes the left and right feet to the corresponding shoe fixtures 54 and rides on the pair of footrests 24.

  Next, when the user wants to start the left turn, he relies on a stock or a support (not shown) to move the center of gravity to the right and move his weight to the right foot, and then tilt his upper body to the left. Let Then, the second moving body 22 starts moving rightward on the rail 46 of the first moving body 20. At this time, the first moving body 20 receives the biasing force from the leftward and rightward biasing springs 36 and 38 and is maintained at the substantially initial position.

  When the second moving body 22 further moves and comes into contact with the stopper 52a of the rail 46, the urging force due to the movement of the center of gravity of the user is applied to the first moving body 20, and the first moving body 20 moves rightward on the rail 26. The leftward biasing spring 36 begins to contract. FIG. 7A shows an initial state of the leftward biasing spring 36, and when the left end portion 36b is pressed by the biasing spring pressing portion 44, as shown in FIG. 7B, three coil springs 40 (1 ), 40 (2), and 40 (3) contract. The amount of contraction is the largest for the coil spring 40 (1) having a small spring constant. When the first moving body 20 further moves rightward, the coil spring 40 (1) eventually reaches the contraction limit as shown in FIG. 7C, and thereafter only the coil springs 40 (2) and 40 (3) contract. .

  When the user tilts the upper body to the left side while maintaining the balance of the body in the left turn, as shown in FIG. However, it tilts to the left with the second hinge 64 at the left end as an axis. Then, the first moving body 20 moves to the right side from the center position of the rail 26, and the right and left legs are applied with a rightward force while the entire body of the user moves to the right side. Receives resilience by 36. At this time, the user in FIG. 6 always receives the leftward biasing force (the elastic force of the leftward biasing spring 36) on the left and right feet at the left end of the fixing member 56.

  The left end serving as an axis when the fixing member 56 is inclined corresponds to the left end (edge metal fitting) of the ski. Therefore, the user can obtain a feeling that “the edge of the snow is raised at the left end of the ski”.

  As the contraction amount of the leftward biasing spring 36 increases, the resilience increases and the leftward biasing force on the first moving body 20 gradually increases. After this, when switching to the right turn after finishing the left turn, if necessary, raise the upper body using stock and support, move the center of gravity to the left side, and gradually move the weight to the left foot, so-called pulling action To start. In this state, the leftward biasing force becomes stronger than the rightward force by the user, the moving direction of the first moving body 20 is reversed leftward, and pushed back toward the center position of the rail 26.

  When the first moving body 20 approaches the center position of the rail 26 and the movement of the user from the left turn to the right turn is completed, the left and right feet on the right side of the upper body are When the first moving body 20 moves to the left and passes the position near the center of the rail 26, the user's body moves to the left together with the first moving body 20. At this time, the moving speed of the entire body approaches the moving speed of the first moving body 20. On the other hand, the left and right feet are fixed on the second moving body 22 that moves relative to the first moving body 20 and can be moved freely with respect to the first moving body 20. It is possible to move to the left side of the upper body at a speed exceeding the moving speed of the body. Therefore, when shifting to the right turn, it is possible to obtain an exaggerated feeling that “the force (reaction force) from the snow surface to the ski is reduced for a short period of time when switching the posture”.

  After that, the left and right are reversed from the above, the second moving body 22 and the first moving body 20 move to the left side of the center position of the rail 26, the rightward biasing spring 38 contracts, and is eventually pushed back to the right. A series of operations are performed.

  As described above, the training device 16 actually slides on the snow surface when performing the turn operation of the ski and the operation of switching the direction of the turn due to the characteristic structure that supports the user's foot. You can create a feeling close to what you are doing. Furthermore, the second moving body 22 can be used by appropriately adjusting the distance or range in which the second moving body 22 can move on the first moving body 20 and the biasing force (the spring constant of the three coil springs 40) by the rightward and leftward biasing springs. Can create a training environment that suits the technical skills of beginners (from beginners to advanced players).

  Next, a second embodiment of the training apparatus for snow sliding sport according to the present invention will be described with reference to FIGS. Here, the same configurations as those of the training device 16 of the first embodiment are denoted by the same reference numerals, and description thereof is omitted. The training device 66 of the second embodiment is a device used for snowboarding training with a snowboard, and as shown in FIG. 8, a base 68, a first moving body 20, a second moving body 70, and feet. The platform 72 is configured. The first moving body 20 is the same as the first moving body 20 in FIG. 4 described above.

  The base 68 has a structure similar to the base 18 of FIG. 3, but instead of the fixed right end holding portion 42 a that holds the right end portion 36 a of the leftward biasing spring 36, a movable right end holding portion 74 a is provided. The configuration differs in that a movable left end holding portion 74b is provided instead of the fixed left end holding portion 42b that is provided and holds the left end portion 38b of the rightward biasing spring 38. The right end and left end holding portions 74a and 74b can move in a direction to absorb an impact, for example, when the user fails to turn and the first moving body 20 hits strongly.

  As shown in FIG. 9, the right end holding portion 74 a has a locking plate 76 that comes into contact with the right end surfaces of the pair of rails 26, and the central position of the rail 26 is positioned slightly inside both ends of the locking plate 76. A pair of extending portions 78 that are straight toward the side are provided. The locking plate 76 is formed with a shaft insertion hole 80 formed at a central position thereof, and the long shaft 34 is inserted with a space inside. Similarly, the left end holding portion 74b has a locking plate 76 that is locked by being in contact with the left end surfaces of the pair of rails 26, and is located at a slightly inner position on both ends of the locking plate 76 at the center position of the rail. A pair of extending portions 78 that are straight toward the side are provided. A shaft insertion hole 80 is also formed in the locking plate 76, and the long shaft 34 is inserted with a space inside.

  The left end holding portion 74a and the right end holding portion 74b are connected to each other through the buffer spring 82 at the tip ends of the extension portion 78, and are pulled toward each other by the urging force of the buffer spring 82 contracting, and The stop plate 76 is locked in a state of being in strong contact with the end face of the corresponding rail 26. The spring constant of the buffer spring 82 is sufficiently larger than that of the rightward and leftward biasing springs 36 and 38 (coil springs 40 (1), 40 (2), and 40 (3)).

  The second moving body 70 is a plate material on which the footrest 24 is fixed on the upper surface. Since this embodiment is an apparatus for snowboard training, only one second moving body 70 is provided. There is one footrest 72 on the second moving body 70, and it supports both the right foot and the left foot (foot with snowboard shoes). Similar to the footrest 24 of FIG. 5, the footrest 72 includes a fixing member 56, a swinging member 58, a lower plate 60, first and second hinges 62 and 64, and 4 on the upper surface of the fixing member 56. Two shoe fasteners 54 are attached. The four shoe fasteners 54 are arranged in pairs on the left and right to fix the toe and heel of the right foot, and the other two to fix the toe and heel of the left foot. Yes. The width dimension of the fixing member 56 in the left-right direction is set to the width dimension of the snowboard board.

  The second moving body 70 and the footrest 72 can be moved in the left-right direction by attaching the second moving body 70 onto the four sliders 48a, 48a, 48b, 48b of the first moving body 20. The left and right end positions to which the second moving body 70 moves are defined by the stoppers 52a and 52b. That is, the second moving body 70 can move in an inner range that does not contact the stoppers 52a and 52b. Although the direction of the foot is the moving direction in the drawing, the mounting direction of the second moving body 70 to the sliders 48a and 48b, the mounting direction of the footrest 72 to the second moving body 70, or shoe fixing The direction of the tool 54 can be appropriately set by adjusting grooves and screws (not shown) according to the user's preference.

  When a force to tilt the support (swing member 58, lower plate 60, first hinge 62, second hinge 64) of the footrest 72 to the left is applied to the fixing member 56, FIG. As shown in (a), the right end is raised about the second hinge 64 at the left end of the fixing member 56 as an axis. On the other hand, when a force to tilt the fixing member 56 to the right is applied, the fixing member 56 is moved by the first hinge 62 at the right end of the swinging member 58 as shown in FIG. The left end is raised with the right end of the shaft as an axis. Therefore, the height of the lowest portion of the fixing member 56 is substantially constant even when the tilting direction or angle changes. This operation is almost the same as the footrest 24 of FIG.

  Next, the operation of the training device 66 will be described. The operations of the second moving body 70 and the footrest 72 are the same as those of the training device 16 described above, and therefore, the operation of the movable right end holding portions 42a and 42b will be mainly described here.

  As shown in FIG. 8, the initial state of the training device 66 is that the first moving body 20 is stationary at the center position of the rail 26 by the biasing from the leftward and rightward biasing springs 36 and 38. Further, the locking plates 76 of the right end and left end holding portions 74a and 74b are in contact with the end surfaces of the rails 26 and are firmly locked. A user wearing snowboard shoes first fixes the left and right feet to the corresponding shoe fixtures 54 and rides on the footrest 72.

  Next, the user changes posture to start the left turn and moves the center of gravity to the left. Then, the second moving body 72 moves rightward on the rail 46 of the first moving body 20. At this time, the first moving body 20 is biased by the leftward and rightward biasing springs 36 and 38 and remains held at the initial position. Further, the right end holding portion 74 b is also held at the initial position by the bias from the buffer spring 82.

  When the second moving body 72 further moves and comes into contact with the stopper 52a of the rail 46, the urging force by the user's movement of the center of gravity is applied to the first moving body 20, and the first moving body 20 moves rightward on the rail 26. The leftward biasing spring 36 begins to contract. FIG. 11A shows an initial state of the leftward biasing spring 36. When the left end portion 36b is pressed by the biasing spring pressing portion 44, as shown in FIG. 11B, three coil springs 40 (1 ), 40 (2), and 40 (3) contract. The amount of contraction is the largest in the coil spring 40 (1) having a small spring constant, and the contraction limit has already been reached in this state. When the first moving body 20 further moves rightward and all the three coil springs 40 reach the contraction limit, as shown in FIG. 11C, the buffer spring 82 having the largest spring constant is extended and the right end holding portion 74a. Moves to the right, and the impact applied to the right end holding portion 74a is absorbed.

  When the user makes a right turn, the left end holding portion 74b and the buffer spring 82 on the opposite side operate in the same manner, and the impact applied to the left end holding portion 74b is absorbed.

  As described above, the training device 66 is used for training to slide on the snow surface with a snowboard, and can obtain the same effects as the ski training device 16. Furthermore, by providing the movable right end and left end holding portions 74a and 74b, for example, even if the user fails the turn operation and the first moving body 20 strongly hits the right left holding portions 74a and 74b, Since the shock is absorbed by the action of the buffer spring 82 and an accident such as damage to the base 68 or the first moving body 20 can be prevented, it is very safe. Further, since safety is ensured without making the rail 26 of the base 68 longer, the entire apparatus can be easily downsized and can be installed in a narrow space.

  In addition, the training apparatus for snow-sliding sports of this invention is not limited to the said embodiment. For example, the structure that enables the first moving body to move with respect to the base uses two linear guides in the above embodiment, but the number of linear guides (or the number of sliders) can be increased or decreased. In addition to the linear guide, the first moving body may be provided with a tire or a roller so as to be movable with respect to a ground surface such as a floor surface. The same applies to the structure that allows the second moving body to move with respect to the first moving body.

  In addition, the leftward and rightward biasing springs are each constituted by three coil springs in the above embodiment, but the number of coil springs can be freely changed. Further, if the above operation is possible, a spring material other than the coil spring may be used.

  The footrest support may also serve as the second moving body as the lower plate of the embodiment. Further, the support is not limited to a structure in which the swing member, the lower plate, the first plate and the hinge are combined as in the above-described embodiment, and when a force to tilt the upper plate to the left side is applied. When the right end is raised with the left end of the upper plate as an axis and a force to tilt the fixing member to the right is applied, the left end with the right end of the fixing member as the axis As long as the operation of raising the end is possible, the structure may be changed to another structure.

  In addition, the shoe fixing tool that fixes the user's foot is one that fixes bare feet, one that fixes a foot wearing shoes (ski shoes, athletic shoes, etc.), and a shoe fixed by a ski or snowboard board fixing tool. Then, the foot may be fixed.

  In the case of the training device 66 of FIG. 8, the buffering spring 82 is a right end side buffering spring (a spring for returning the right end holding part 74a to the original position), and the left end side buffering spring (the left end holding part) However, for example, a right end side buffering spring and a left end side buffering spring may be provided separately.
