Description

[Detailed Description of the Invention] The present invention relates to ski parts. Skiing, a winter sport, has become popular, and the number of people who have mastered skiing techniques is increasing year by year. However, there are people who visit ski resorts once or twice every winter to ski, but because they are unable to stay overnight and practice skiing, they remain inexperienced beginner skiers year after year. Therefore, the present invention provides a Christiania sliding aid for skiing that allows such people to enjoy skiing as quickly as possible. Next, the present invention will be explained in detail with reference to the drawings of one embodiment. FIG. 1 is a side sectional view of a conventional ski. A vertically elongated edge 2 made of steel is provided to the sliding surface from the front part a to the rear part b on both sides of the ski stand 1. Etsuji 2 improves the ski's glide ability and performance. When making a turn while skiing, take off your weight from the rear part of the ski, push your knees into the inside of the ski's turn, bend, remove the edge on the outside of the turn, make the tail swing, and turn the ski on the inside of the turn to the outside of the turn. The technique of ski down rotation, such as turning to the ski, turning to the right, turning to the left, turning to the mountain side, turning to the valley side, etc., is to apply weight to the ski with the right foot and left foot, weight from the back of the ski when swinging the tail of the ski, weight to the front of the ski, and weight to the front of the ski. In addition to the importance of consideration such as transfer, it is especially important to instantaneously obtain a fulcrum for the tail swing rotation as the weight is transferred to the front of the ski when swinging the ski tail. Requires practice time. 3 is a ski boot fixing fastening fitting. 4 is the ground snow surface, and c and d are the contact portions of the sliding surface of the ski stand 1. Second
The figure is a cross-sectional view of the ground-contacting portion c of the ski stand 1 in FIG. 1. FIG. 3 is an external appearance diagram of an embodiment of the present invention. The tightening turnbuckle structure 5 has a hexagonal nut-shaped part in the center of a screw 7 having reverse threads on the left and right sides, and a spanner (not shown) is fitted into the nut part to tighten the screw 7 to the ski base. 1, the buckle portions 5a screwed on both sides of the screw 7 are expanded and contracted outward or inward by rotating the buckle portions 5a on both sides of the screw 7. The holes are made eccentric to obtain a variable protrusion height of the elliptical edges 6, 6, and the screwed together assembly has rectangular or elliptical edges 6 with rounded edges at both ends as shown in this figure. Punch out the buckle 5 by removing the fixing or tightening screw 7 symmetrically.
a and the edge 6 are integrally molded, the buckle portion 5a is provided with a polygonal surface to prevent rotation of the edge 6, and the polygonal surface 5an is numbered or coded. The protrusion height of the edge 6 from the ground plane of the edge 2 of the ski stand 1 is displayed, and the protrusion height of an arbitrary edge 6 is obtained by selecting the polygonal surface 5an. As described above, the polygonal surface 5 of the buckle 5a is a device for varying the protrusion height of the edge 6.
It is better to make the width of an as wide as possible to prevent unnecessary rotation of the edge 6 and to secure it stably.
FIG. 4 is an external shape diagram showing one usage mode of the device shown in FIG. Bring the polygonal surface 5an of the buckle 5a into close contact with the surface side 1a of the front contact surface c of the ski stand 1, and turn the tightening screw 7 in the forward direction or backward direction of the tip a of the ski stand 1. In particular, each buckle 5a is screwed inwardly against the width of the ski stand 1 to form an elliptical edge 6,
By tightening and fixing the edge 6 to the ski board 1, the edge 6 is tightened and fixed so that its protruding height from the skiing surface matches the height indicating code described above. FIG. 5 is a sectional view of the portion of FIG. 4 where the edge 6 is fixed. The elliptical edge 6 illustrated in FIGS. 3 and 4 and explained above is located on both sides of the ground-contacting portion of the tip runner surface at the front of the right and left ski bases 1 from the gliding surface of the edge 2. Since it protrudes to a desired height, when skiing, you can remove your weight from the rear of the ski platform 1 during the rotation, and at the same time push your knees inside the rotation and bend to remove the edge 2 on the outside of the rotation while skiing. 1 unit
When the tail swings, it becomes the operating fulcrum for its rotation. Therefore, the fulcrum braking action for rotations to the left or right, to the mountain side or to the valley side, etc., is effective with Edge 6, and it is extremely easy to obtain a small rotation radius, so even beginners can ski crisp with a short amount of practice. I was able to master the technique of gliding. FIG. 6 is a schematic side view showing one mode of use of an embodiment of the present invention. A device in which the edges 6, which are Christiania sliding aids for skiing shown in FIG. A polygonal surface 5an having a shape is brought into close contact with the table surface 1a of the assembled part. As described above, according to one embodiment of the present invention, it is possible to considerably shorten the previously required skiing practice time, and it is possible to obtain skiing and rotational Christiania extremely easily from the effects of Edge 6. As a result, it has become possible to acquire advanced skiing techniques in a shorter time than before.
