Description

[Detailed explanation of the idea] Industrial applications This invention relates to a ski training machine.

BACKGROUND TECHNOLOGY In general, hip movement is a much more important element than leg movement in order to improve snow skiing. Therefore, the best way to practice these leg and hip movements is to go to a ski resort.
There's no way to practice in the offseason. In particular, it would be great if there were a machine or device that could make it easier to practice skiing indoors, but such a machine or device has not yet been provided.

Problems that the invention aims to solve Therefore, this invention can create a realistic skiing situation, and not only move the legs and hips, but also
The purpose was to create a ski training machine that could be used to easily train one's ski skills indoors.

Means for Solving the Problems In order to solve the above problems, this invention has a pair of shafts supported vertically on a base so as to be freely rotatable, and one end of each arm can be freely rotated horizontally on the shafts. A fixed shaft is rotatably supported at the other end of the arm, and the other end of the arm is connected by a connecting rod in which the fixed shaft is implanted to form a parallel link, and the connecting rod A coil spring is stretched between the fixed shaft and the base, and a bevel gear is attached to the upper end of the fixed shaft, and a shaft having a bevel gear that meshes with the bevel gear is attached to the arm, and the shaft is rotatable to each of the arms. A ski training machine is constructed by supporting the shaft and integrally connecting the footboards to the shaft.

Action: When the practitioner places his or her feet on the footboard and swings his or her hips to the left or right, the arm rotates in the opposite direction around the axis of the base, and the connecting rod displaces, pulling the coil spring. The fixed shafts both rotate in opposite directions, the shafts rotate in the same direction via the bevel gear, and the footboard tilts in the same direction as the hip moves. The inclination angle of the tread gradually changes until the arm reaches its maximum swing. When the arm is rotated in the opposite direction, the force stored in the coil spring assists the arm to rotate in that direction, thereby promoting smooth reciprocating motion. Therefore, by repeating the left and right reciprocating movements of the arms, you can practice skiing in a realistic manner.

Embodiment An embodiment of this invention will be described below based on the drawings. As shown in FIGS. 1 to 3, a rectangular base 3 is mounted approximately at the center of a frame 2, which has stable frames 1, 1 that extend left and right in the shape of roughly triangular wings. A rotary base 4 is provided at one end of the rotary base 3, and poles 5, 5 are respectively erected on both left and right sides in the vicinity thereof. Levelers 2a are attached to the lower surface of the frame 2 near both corners of the base 3 and at the apex of the triangle, respectively, so that the stability or horizontality of the frame 2 can be adjusted.
The poles 5, 5 have a length of 1.5 to 2.0 m, which is approximately the same as the height of a person, and have grip parts 5a, 5a at their upper ends.
is installed. The rotating base 4 has a pair of left and right shafts 6, 6 rotatably supported perpendicularly to the base 3 by brackets 7, 7, and one end of arms 8, 8 of a predetermined length are attached to the shafts 6, 6. are connected to each other, and the arms 8, 8 are supported in a horizontal position so as to be rotatable in the left and right directions. Brackets 9, 9 are attached to the other ends of the arms 8, 8, respectively, and fixed shafts 10, 10 are rotatably supported on the brackets 9, 9, respectively.
The lower end of is fixed vertically to the connecting rod 11. That is, the arms 8, 8 and the connecting rod 11 constitute a parallel link. A connection in which one end of a plurality of compressible coil springs 12 (one is shown) is connected to the approximate center of the connecting rod 11, and the other end of the coil spring 12 is connected to the approximate center of the base 3. It is engaged in a hole 13a bored approximately in the center of the plate 13. On the other hand, a bevel gear 14,
Shafts 16, 16 having bevel gears 15, 15 which mesh with the bevel gears 14, 14, respectively, are rotatably supported on the upper surfaces of the hooms 8, 8 via brackets 17, 17, respectively. let The shafts 16, 16 each have a foot plate 1.
8 and 18 are integrally attached by plates 18a, 18a, 18a. The footboard 18 is a thin, shallow box-shaped thing with a predetermined length that is open on the rotating base 4 side, and is an alternative to skis. Incidentally, stoppers 19, 19 are vertically provided on the frame 2 at opposite positions sandwiching the base 3 therebetween.

Next, the operation of the above embodiment will be explained.
When practicing, the practitioner first holds poles 5 and 5 with both hands.
The user grasps the upper end of the machine and the grip portions 5a, 5a, then places the left and right feet on the footboards 18, 18, respectively, to allow the machine to support the body, and then swings the body left and right.
When you swing your hips to either the left or right, the footboards 18, 18 at your feet swing together in the opposite direction, and stop within a predetermined swing range, and the coil springs cause the footboards 18, 18 to move further in the opposite direction. It recoils to encourage smooth movement of the hips. That is, as shown in FIG. 5, when the arms 8, 8 are positioned on the base 3 and the user moves the waist to the left, the arms 8, 8 rotate to the right. Then, as the connecting rod 11 is displaced in conjunction with the clockwise rotation of the arms 8, 8, the fixed shafts 10, 10 are rotated clockwise, as shown by the solid line in FIG. 6, and the bevel gears 14, 14 are respectively Turn clockwise,
This causes the bevel gears 15, 15 to rotate counterclockwise. Therefore, the shafts 16, 16 both turn clockwise and rotate at the same angle, which causes the footboard 1 to rotate.
8 and 18 are tilted to the right at the same angle. Therefore, the footboards 18, 18 are gradually inclined to the extent that the right arm 8 abuts the right stopper 19, allowing the practitioner to realize the same situation as running on a ski resort. Furthermore, when one of the arms 8, 8 swings to the extent that it comes into contact with the stopper 19, 19 or stops just before it, the connecting rod 11
is displaced while rotating, the coil spring 12 is pulled and stored, and the arms 8, 8 are moved to the base 3.
It has the effect of returning it to its original position parallel to . Therefore, when the practitioner moves his hips to the right, arms 8 and 8
is smoothly rotated to the left without applying force to the waist, and the footboards 18, 18 can both be gradually tilted to the left at the same angle as shown by the imaginary lines in FIG. Therefore, a reaction to the left and right swinging of the arms 8, 8 is naturally generated in the coil spring 12, allowing smooth movement, and when the back and forth movement of left and right swinging is repeated, the situation is the same as in actual skiing. You can practice with.

Note that the maximum inclination angle of the footboard 18 is the same as that of the bevel gear 1.
It goes without saying that it can be arbitrarily determined by appropriately setting the ratio of the number of teeth between 4 and 15.

Effects of the invention According to the invention explained above, when you swing your hips to either the left or right, your feet swing in the opposite direction and stop within a predetermined swing range, and the coil spring causes your feet to recoil. It also encourages smooth movement of the hips in the opposite direction, so you can easily practice indoors, etc. to develop the same feeling as actually skiing, as well as the movement of the legs and hips by reciprocating the left and right movements of the feet. It is convenient for ski enthusiasts and athletes to practice during the off-season.
