Abstract

PROBLEM TO BE SOLVED: To provide a skiing aid that aids a skier so that he can ski smoothly at high speed by absorbing vibrations and impacts transmitted from skis. SOLUTION: A plate spring 12 that pushes the heel side bottom surface of a ski boot 30 upward with the tee box side of the ski boot 30 as a fulcrum and a plate spring 1-1 that applies an elastic force to bend toward the snow surface side of the ski 20 are mounted between the upper surface of the ski 20 and the heel of the ski boot 30. If impacts or vibrations from the snow surface are applied in addition to the body weight of the skier, the interval between the plate springs 11, 12 narrows and the vibrations and impacts are absorbed to help the knee of the skier absorb the vibrations. Also, the action of the plate spring 12 to warp the ski 20 upward is canceled out by the action of the plate spring 11 to warp it downward, so that subtle elasticity of the ski 20 is not impaired.

The present invention operates as follows. Elastic members (11, 12) are arranged between the upper surface of the ski (20) and the bottom surface of the ski boot (30), thereby absorbing the impact from the snow surface. The skier is assisted by absorbing the vibrations and shocks transmitted from the ski (20) by the elastic members (11, 12), so that the dependence on the flexibility of the knee is reduced, and the decrease in muscle strength and wasting of physical strength are suppressed. Can be Thereby, smooth and high-speed running can be maintained for a longer time. Even for beginners or intermediate level players with insufficient knee flexibility, the elastic members (11, 12) absorb vibrations and shocks, so that smooth and high-speed sliding can be enjoyed relatively easily. Become.

Further, the bottom surface near the heel of the ski boot (30) is pushed upward by the elastic members (11, 12). Since the skiing is performed in a forward leaning position, it is desirable that the toe side of the ski boot (30) has a sense of unity with the ski (20) in order to maintain a stable position and accurately determine the direction of the skiing. By pushing up the bottom of the ski boot (30) near the heel by the elastic members (11, 12), the stability of the posture can be secured while absorbing the impact.

Further, the bottom surface of the ski boot (30) is pushed upward from the heel of the ski boot (30) by the first elastic member (12), and the elastic force in the direction of bending toward the snow surface side by the second elastic member (11). Add to plate (20).

Although the ski (20) originally has an arcuate shape slightly curved toward the snow surface side, the first elastic member (12) moves the heel side of the ski boot (30) upward. The push-up reaction exerts a force in the direction of flattening the bowed ski (20). Then, an elastic force in the direction of bending to the snow surface side by the second elastic member (11) is applied to the ski (20), and the reaction by the first elastic member (12) is canceled, and the ski (20) itself is removed. The inherent elasticity is maintained.

The elastic members (11, 12) are composed of two leaf springs arranged facing each other. These leaf springs (11, 12) are fixed at one ends (11a, 12a) and warp in a direction away from each other toward the other ends (11b, 12b). By using such a leaf spring as the elastic member (11, 12), the elastic force acts evenly in the width direction of the ski (20) and the twist in the width direction is small, so that the edge of the ski (20) is formed. Can be set as intended.

The ends (11a, 12a) of the two leaf springs (11, 12), which are fixed to each other, face the tip of the ski (20), and the ends are skied. The other ends (11b, 12b) of the leaf springs (11b, 12b) are held upward by a downward U-shaped holding member (15) which is fixed to the plate (20) and regulates the swinging of the leaf springs (11, 12) in the left-right direction. To fix the lower end of the holding member (15) to the ski (20).

The leaf springs (11, 12) are mounted on a ski (20).
And the other end is indirectly fixed to the ski (2) via a downward U-shaped holding member (15).
0), the other end (11b, 12b) can change its relative position with the ski (20). This allows you to attach it to the ski (20)
The elastic force of the leaf springs (11, 12) is not lost.

The elastic member is constituted by a leaf spring having a substantially U-shape or an annular cross section that is flattened into a tapered shape, so that the leaf spring on the ski side and the ski boot side are also provided on the toe side. The distance between the leaf springs can be widened. As a result, snowflakes and ice are less likely to be caught in the gaps between the leaf springs, and even if caught, it is easy to remove them, so that the performance of the spring can be maintained without change during sliding.

Further, a stopper (40) for detachably fixing the ski boot (30) is attached to the elastic members (11, 12). Thereby, the same convenience as the ski (20) without the elastic members (11, 12) can be secured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Various embodiments of the present invention will be described below with reference to the drawings. 1 to 6 show a first embodiment of the present invention. As shown in FIG. 1, a skiing aid 10 includes two leaf springs 11, 1 as elastic members.
2 and their rear end sides 11b, 12b
It is constituted by a holding fitting 15 for indirectly holding at 0. The skiing aid 10 is attached to the upper surface of the ski 20, and the ski boot 30 is mounted on the upper surface of the leaf spring 12.
A binding 40 for detachably fixing the screw is screwed.

FIG. 2 shows the elastic members 11 and 12 of the skiing aid 10. The two leaf springs 11 and 12 as elastic members are arranged facing each other,
The tip portions 11a and 12a are fixed to each other. The leaf springs 11 and 12 have rear ends 11b and 12b, respectively.
They are warped away from each other. Leaf spring 1
The width of 1 and 12 is almost the same as the width of the ski 20. The leaf springs 11 and 12 have sufficient rigidity against torsion.

The binding 40 is divided into a toe-side fixing part 41 and a heel-side fixing part 42. The toe-side fixing part 41 is provided with a screw hole (not shown). The tip ends 11a and 12a of the leaf springs 11 and 12 are provided with screw holes (not shown) at positions corresponding to the screw holes of the toe side fixing portion 41.

The leaf springs 11 and 12 are arranged on the upper surface of the ski 20, and the toe-side fixing portion 41 is mounted thereon with the screw holes aligned with each other, and the fixing member is inserted into the screw hole from the toe-side fixing portion 41 side. Of the leaf springs 11a, 12a
The toe side fixing portion 41 is screwed to the ski 20. The rear end 12b of the leaf spring 12 is provided with an elongated screw hole (not shown) in the longitudinal direction of the leaf spring 12, and a screw inserted from the inside of the leaf spring 12 through the screw hole. Is the rear end 12b of the leaf spring 12.
Mounted on top. The attachment position of the heel-side fixing portion 42 is adjusted by the elongated screw holes.

Rear ends 11b, 12b of leaf springs 11, 12
Are attached to the ski 20 by holding brackets 15. As shown in FIG. 3 and FIG. 4, the holding bracket 15 has a shape in which both sides of the lower end of a U-shaped bracket are bent inward, and the holding bracket is bent to the fixed seat portion bent inward. A screw hole is provided for attaching 15 to ski 20.

The rear end 11b of the lower leaf spring 11 facing the ski 20 is cut off at both lateral ends, and has a width smaller than the gap between the front ends of the fixed seats. .
The inner size of the U-shaped portion of the holding bracket 15 is set equal to the width of the upper leaf spring 12.

The rear end portion 12b of the upper leaf spring 12 is inserted inside the holding bracket 15, and the leaf spring 1 is
In a state in which the holding seats 1 and 12 are pressed from above toward the ski 20, the fixing seat of the holding bracket 15 is screwed into the ski 20.
Attached to.

FIGS. 5 and 6 show a state in which the skiing aid 10 and the binding 40 are attached to a ski. As shown in FIG.
In a state in which no is mounted, the flow stopper 43 of the binding 40 rotates, and its lower end faces downward. The mounting position of the binding 40 becomes slightly higher by inserting the ski assisting tool 10, but the lower end of the flow stopper 43 can sufficiently extend below the lower surface of the ski 20 in a state where the binding aid 40 faces downward. Has become.

Next, the operation will be described. As shown in FIG.
The upper side leaf spring 12 includes a tip 12 a and a holding bracket 15.
And exerts a force in a direction of causing the ski 20 to warp upward with a point of contact as a force point. On the other hand, the lower side leaf spring 11
Exerts a force for bending the ski 20 downward with the tip 11a and the rear end 11b as points of force. Therefore, the action of the leaf spring 12 to deflect the ski 20 upward is canceled out by the action of the leaf spring 11 to deflect downward, the bow-like curvature inherent in the ski 20 is maintained, and the delicate elasticity of the ski 20 is lost. I can't.

When the weight of the skier is added to the ski aid 10, the leaf spring 12 does not move downward. When vibration and shock from the snow surface are added to the weight of the skier,
The distance between the leaf springs 11 and 12 is reduced, and vibrations and impacts are absorbed by the leaf springs 11 and 12. As described above, since the ski assisting device 10 assists the skier in absorbing the impact by the knee of the skier, the decrease in muscle strength and the consumption of physical strength of the skier are reduced, and it is easy to maintain smooth and high-speed running.

For example, when skiing on an uneven snow surface, the ski 20 itself moves up and down substantially along the snow surface.
Since the impact and the like are absorbed by the skiing aid 10, the skier's body is prevented from being displaced up and down. That is, the kinetic energy is not spent on the up and down movement of the skier, and a decrease in the sliding speed is prevented accordingly. Further, since the vibration is smoothly absorbed, the resistance between the snow surface and the ski is reduced, and high-speed sliding is enabled.

The tip portions 11a of the leaf springs 11, 12
12a is fixedly attached to the ski 20 and the rear ends 11b and 12b of the leaf springs are indirectly attached by the holding bracket 15, so that the ski 2
When the curvature of the zero plate changes, the rear ends 1 of the leaf springs 11 and 12 are changed.
1b and 12b change the relative position with respect to the ski 20 or the holding metal 15 and slide.

When both the front and rear ends of the leaf springs 11 and 12 are fixedly attached to the ski 20, the skis 20 cannot be bent freely by the leaf springs 11 and 12, and The elasticity of the leaf springs 11, 12 is impaired by the ski 20. In the ski assisting device 10 shown in each figure, only the front end portions of the leaf springs 11 and 12 are directly fixed to the ski 20 and the rear end portions (11b and 12b).
Since b) is slidably held by the holding metal 15, the ski 20 can be bent freely, and the elastic force of the leaf springs 11 and 12 is not impaired.

The width of the upper leaf spring 12 and the holding metal 15
Are substantially equal to each other, so that the holding bracket 15 restricts the swinging of the leaf spring 12 in the left-right direction. Further, the width of the leaf springs 11 and 12 is made substantially the same as that of the ski 20 and a material having high rigidity against torsion is used. Can work.

FIG. 7 shows a skiing aid 10 according to the second embodiment. In the embodiment shown in FIG. 1, both the toe-side fixing portion 41 and the heel-side fixing portion 42 of the binding 40 are fixed on the leaf spring 12, but in the second embodiment, the toe-side fixing portion 41 Is attached to the ski 20 separately from the ski aid 10.

The lengths of the leaf springs 11 and 12 are shorter than those shown in FIG. The screw hole for attaching the heel-side fixing portion 42 provided in the leaf spring 12 has a circular shape, and the attachment position of the heel-side fixing portion 42 is fixedly determined.

According to the optimum mounting position of the binding 40 on the ski 20, first, the toe side fixing portion 41
Is screwed to the ski 20. The mounting position of the skiing aid 10 is adjusted in accordance with the size of the ski boot based on the toe side fixing portion 41.

As described above, only the heel-side fixing portion 42 is fixed to the ski assisting device 10, and the toe-side fixing portion 41 is connected to the ski 2
By attaching the ski boot separately to the ski aid 10, the allowable range of the size of the ski boot can be widened. Further, since it is not necessary to make the hole for attaching the heel-side fixing portion 42 provided in the upper leaf spring 12 into an elongated hole, a decrease in rigidity of the leaf spring can be suppressed.

FIG. 8 shows a skiing aid according to the third embodiment. Here, as shown in FIG. 9, a plate-shaped spring (hereinafter, referred to as a ring-shaped spring) 50 having an annular cross section squashed flat into a taper is used as an elastic member. A spacer member 52 is inserted inside the toe side portion of the ring-shaped spring 50. In the ring-shaped spring 50, a portion near the toe of the plate spring facing the ski 20 side is directly screwed to the ski 20. Ring type spring 50
The rear end portion is fixed to the indirect ski 20 by the holding member 15, as in the case of the first embodiment shown in FIG.

The ring-shaped spring 50 has a certain distance between the ski-side plate spring and the ski-boot-side plate spring at the toe-side portion, and the plate-like spring has a thickness less than its thickness by sandwiching the spacer member 52. The distance between the toe portions of the springs is not reduced. This makes it difficult for snowflakes and ice to be caught in the gaps between the leaf springs, and even when they are caught, it is easy to remove them, so that the performance of the springs can be maintained without change during sliding.

Also, as in the first and second embodiments,
The structure is simpler than in the case of using a single leaf spring, the manufacturing is easy, and a failure is unlikely to occur. further,
Since the heel side portion is not formed as an open end but is formed as an annular ring in cross section, rigidity against torsion is increased, and it is possible to further raise the edge as intended by the skier.

In addition, the section as shown in FIG.
It is also possible to use a plate-shaped spring folded in the shape of a letter as an elastic member. The U-shaped leaf springs 60 warp in a direction in which the folded leaf springs move away from the folded portion 62 toward the end 64, and generate elastic force in a direction of separating the ends 64. Have. The U-shaped plate spring 60 has the folded portion 62 side disposed on the toe side of the ski.

Although not shown, the U-shaped leaf spring 60 has a spacer member 52 interposed at the toe side like the ring spring 50. Further, the toe portion of the leaf spring facing the ski side is directly screwed to the ski, and the end portion 64 side is similar to the case of the first embodiment.
It is indirectly fixed to the ski by the holding member 15.

When a U-shaped leaf spring 60 is used,
As in the case of the ring-shaped spring 50, the interval between the plate-shaped springs on the toe side can be secured to a certain degree or more, so that snowflakes and ice are hardly caught in the gap between the plate-shaped springs. Is easily removed, so that the performance of the spring can be maintained without change during sliding.

[0048]

According to the skiing aid of the present invention,
The elastic member installed between the ski and the bottom of the boot absorbs vibrations and shocks transmitted from the snow surface, thus assisting the absorption of vibrations, etc. caused by the flexible bending and stretching of the skier's knees, reducing the burden on the skier. Can be. As a result, a decrease in muscle strength and a decrease in physical strength of the skier are reduced, and smooth and high-speed running can be maintained for a longer time.
