Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a running exercise equipment.

More particularly, it is a running exercise equipment having the same performance, function and sensation as a snow ski, especially a cross-country snow ski, on land.

In other words, it is provided with both one side of a completely new genre of running exercise equipment and a running exercise equipment which can be used for off-season play of snow skiers.

This makes a great contribution to the industrial field in which it is difficult to effectively use the ski area during the off-season, and there has been a long-felt need for the development of sports equipment capable of a more full-scale all-season business.

The present invention is a tool made possible by such socially very strong demands and technological innovations concerning wheels, and relates to a running exercise tool which can be called a vertical / horizontal running exercise tool or an omnidirectional running exercise tool. Out.

[0006]

2. Description of the Related Art Conventionally, JP-A-56-8077 (hereinafter referred to as a conventional example) has been proposed as a running exercise tool that is said to be enjoyable in the same sense as a cross-country snow ski. In this conventional example, a plurality of wheels are rotatably supported on a substrate, and at least one of the plurality of wheels is internally equipped with a one-way clutch to rotate only in the traveling direction.

[0007]

As a result of various researches by the applicant, it was confirmed that the conventional example has the following drawbacks.

In the conventional example, the stop wheel in which the one-way clutch is installed is provided so as to be always in contact with the ground, so that the operation feeling is completely different from that of the snow ski.

That is, in cross-country snow skiing, generally, a slippery wax is applied to the front and back of the ski, a non-slip wax (stop wax) is applied to the center, and the ski is alternately kicked backward and stepped forward. Advance.

If the ski is weighted when kicking backwards, the portion of the stop wax will come into contact with the snow surface and the stepping force will be increased.

By the way, in the conventional example, since the stop wheel is always in contact with the ground contact surface, it does not slip backward even if the driver does not step firmly on it when moving forward like a snow ski.
In this respect, the operation feeling is completely different from that of snow skiing.

When climbing uphill with snow skis,
People with strength and technique will have to step firmly on the ski to make the stop wax work, and then ski uphill, but for people without strength and technique, open the ski in a V shape to prevent it from slipping down. Have to climb uphill.

When the stop wheel is always in contact with the ground, it does not slip down on an uphill slope, so that it is not necessary to step on it firmly, and therefore it is not necessary to open the ski in a V shape.

Therefore, when the conventional example is considered as a training tool for snow skiing, it is not a tool for improving the sliding technique in snow skiing.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a running exercise tool which exhibits characteristics completely equivalent to those of snow skis, especially cross-country snow skis.

[0021]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawing is an embodiment designed as a running exercise tool for enjoying land skiing with the same feeling as Nordic skiing.

1 to 7 show an embodiment according to the present invention.

In the embodiment, a pair of left and right is used.

A stop wheel mounting plate 21 is provided at the front end of the main substrate 7.
This stop wheel mounting plate is fixedly connected by rivets.
The front wheel support plate 8 is fixedly connected to the front end of 21 by bolts and nuts, and the sled plate 10 is fixedly connected to the front end of the front wheel support plate 8 by bolts and nuts. The rear wheel support plate 8 is fixedly connected by bolts and nuts, and a binding 12 for fixing shoes is fixed at an appropriate position on the main substrate 7.

An elastic tire 4 having a structure described later is pivotally supported on the front and rear wheel support plates 8, and a stop wheel 6 having a structure described later is pivotally supported on a rear end of the front wheel support plate 8. A wheel 11 is pivotally supported at a central position of the sled plate 10. The sled plate 10 eliminates instability when the kick leg is flipped up backward, and the sled plate 10 is flexible in the vertical direction, so that a soft touch feeling can be obtained.

Reference numeral 14 is a cover.

The structure of the elastic tire 4 will be described with reference to FIGS.

A bearing cylinder 16 is fitted on the shaft 15 fixed to the front and rear wheel support plates 8, a support plate 18 protruding outward is fixed to this bearing cylinder 16, and the outer end of the support plate 18 is fixed to the outside. A brim plate 9 having a V-shaped cross section that spreads in a curved state toward one side is fixed. A metal core disk 19 as shown in FIG. 3 is disposed between the C-shaped flange plates 9, and a rubber tire member 17 is fixed to the core disk 19. The elasticity of this tire member 17 is appropriately designed. The core disc 19 shown in FIG. 3 has a structure in which branch portions 19 "are integrally and radially provided on a disk-shaped central portion 19 ', and the tip of the central portion 19' is divided into three parts. 2, both ends of the three parts are bent at a predetermined angle with respect to the central portion 19 ', and the center of the three parts is bent at the same angle on the opposite side. Various designs are possible.

Incidentally, FIG. 4 shows an elastic tire 4 having a structure different from those of FIGS.

The stop wheel 6 has the following structure as shown in FIG. 5 and FIG. 6, and the wheel 3 (elastic tire 4) with respect to the ground contact surface.
A shaft 22 is installed on a stop wheel mounting plate 21 which is disposed slightly above (the distance between the lower edge of the stop wheel 6 and the ground contact surface is L) and also serves as a cover, and a roller escape recess is formed on the inner peripheral surface. A receiving cylinder 24 having 23 formed therein is fitted onto the shaft 22, and a board 27 serving as a tire member is fixed to the receiving cylinder 24. Between the inner peripheral surface of the roller relief recess 23 and the outer peripheral surface of the shaft 22, an appropriate number of rollers 25 are continuously connected by springs 26, so that the so-called one-way clutch mechanism 5 is provided.

Reference numeral 20 is an elastic member, and 13 is a lateral movement restricting member for the roller 25.

FIG. 7 shows another example in which the elastic tire 4 is pivotally supported in a cantilever state.

Although various types of running exercise equipment for land have been proposed in the past, various types have been proposed. However, considering whether they have the same performance and function as snow skis, the following points are still inadequate and incomplete. Is.

Conventional products generally have a rotating body attached to a substrate, a frame, etc., but rollers, wheels, caterpillars, etc. are used as the rotating body. However, in both cases, because the lateral running is incomplete and incomplete, the skiing function, which is the basic function of snow skiing, and the edging function (an important function to perform while skidding) are not provided as running functions.

Therefore, in the conventional product, the functions such as the plow, the plow bogen, the braking, and the cornering function accompanied by the sliding phenomenon due to the twisting and pushing operation of the tail portion are impossible or extremely difficult to operate.

Among the conventional products, for the cross-country use such as rollers and wheels, the use conditions are regulated due to the phenomenon as described above, and particularly when used on a downhill, the braking function is insufficient and the rotation function is not effective. It cannot be used due to player's safety measures such as defects.

Among the conventional products, for the alpine for which the caterpillar is used, in addition to the same phenomenon as described above, the alternate operation of stepping, which is a basic function of snow skiing, is impossible for safety reasons. That is, the conventional product using the caterpillar must always load both legs. Since the rotation resistance of the caterpillar is large due to the structure, the rotation of the caterpillar stops on the non-grounded side. Therefore, the spin phenomenon occurs due to the resistance when grounding again, and the balance is lost and the vehicle falls.

In general, a snow ski has a load on the ski (load due to the weight of the skier, weighting, and movement of the center of gravity).
And the action of the ski edge (edging operation) produces various performances, functions and effects. That is, it is operated by an appropriate and rational body movement based on the sensory function of the skier. Therefore, even in the case of running exercise equipment for land use, when the equipment having the same performance and function is used, the operability by feeling cannot be ignored, and the conventional product cannot solve this point.

As described above, since the conventional products cannot exhibit the characteristics of snow skis, they cannot run on the same level. In the end, at present, there is no running exercise equipment that can be played with the same feeling as snow skis.

For snow skis (including both alpine and cross-country skiing), a) downhill function, b) skid function, c) braking function, and d) rotation function are the most important functions. And for cross-country snow skiing,
E) The walking function is also important. Since the present embodiment has the above-mentioned configuration, it sufficiently exhibits the above-mentioned 5 functions.

(B) Downhill function Straight downhill When the tire of this embodiment is set in front of the fall line of the slope, the elastic tire 4 rotates, and in this embodiment, the vehicle travels forward and straight along the fall line.

Even if the stop wheel 6 comes into contact with the ground contact surface, the stop wheel 6 is capable of traveling forward and rotating, so that traveling is not hindered.

Oblique Downhill When the present embodiment is installed obliquely with respect to the fall line and the vehicle travels straight forward (see FIG. 8), the pitch of the elastic tires 4 in contact with the ground flexes in the direction orthogonal to the running direction, and the amount of the flexion However, the entire embodiment, except for the ground contact portion, moves laterally. As the elastic tire 4 rotates, the next pitch comes into contact with the elastic tire 4, and the elastic tire 4 similarly bends and laterally moves. This is continuous and this embodiment skids
Slope down accompanied by (lateral displacement in the fall line direction)
(See Figure 9).

At this time, if the load for bending the pitch of the elastic tire 4 in contact with the ground does not act because the slope of the slope is small or the slope of this embodiment with respect to the ground contact surface is small, the embodiment is not possible. Is a downhill slope without skidding (see Fig. 8). (B) Side-slip function This embodiment is held at a right angle to the fall line on the slope and brought into a stopped state. At this time, the ground contact pitch of the elastic tire 4 is bent, and the center of gravity is closer to the fall line than the center of the ground contact pitch (see FIG. 10). From the stopped state, when this embodiment is run before or after (rotating the elastic tire 4), by the continuous operation of bending when the next pitch touches the ground and bending when the next pitch touches the ground, In this embodiment, the skid of the slope starts downward (see FIG. 11).

C) Braking function Standing on a flat surface When standing vertically on a flat surface, the front and rear elastic tires 4 are loaded almost evenly (the distribution ratio may differ slightly depending on the shoe attachment position). This example is stable.

Stopping on a slope Hold the left and right embodiments of the present invention in an inverted V shape (the slope lower side is narrower and the upper side is wider) toward the fall line of the slope and incline inward, and the left and right equal loads (left foot to left, right foot to left Is applied to the right side to push the present embodiment outwardly) and stopped on the slope (see FIG. 12).

At this time, the present embodiment on the right side moves to the lower left of the slope,
In the present embodiment on the left side, the respective forces that try to run to the lower right of the slope act, and the stopping state is maintained on the slope by balancing the force pushing outward from both feet. In this case, the grounding pitch of the elastic tire 4 is bent.

Sliding from a stop on a slope When the angle of opening in an inverted V shape from the above stopped state is reduced,
Since the direction of this embodiment approaches the fall line direction, the force of pushing and opening to the left and right and the force working to rotate the elastic tire 4 (right side to the lower left of the slope, left side to the lower right of the slope) are equalized. The balance is broken and the elastic tire 4 starts to rotate.

Since each pitch of the elastic tire 4 bends when it comes into contact with the ground, the running of the elastic tire 4 and the lateral movement of each pitch allow the present embodiment to run with side slip.

As a result, the product of the present embodiment remains in an inverted V shape, and the descent gradually starts toward the fall line.

Then, when the angle of opening in the inverted V shape is increased again from this running state, the direction of this embodiment approaches the direction orthogonal to the fall line, so that the force for rotating the elastic tire 4 is exerted. It also weakens, and the pitch at which it touches the ground becomes the maximum deformation, and the resistance in the lateral direction (the lateral direction is as shown in FIG. 13 when viewed from this embodiment, but when viewed from the running direction, it is obliquely rearward as shown in FIG. 14). ) Becomes larger and the run is gradually braked.

D) Rotational function In the state where the fall line described in c) is sliding in an inverted V shape, either one of the left and right loads of this embodiment is reduced or one of the loads is increased. Then, since the force of advancing in the rotation direction of the elastic tire 4 is larger in the present embodiment on the side where the load is relatively larger, the rotational movement starts to the side where the load is smaller (see FIG. 15). This is because the larger the load is, the larger the force is decomposed downward along the slope.

At this time, diagonally below the slope (side with a small load)
Direction without turning straight (see Fig. 16), it is the player's heel push-out action, the load distribution of the front and rear elastic tires 4, the flexibility of the front and rear elastic tires 4, etc. This is because the amount of sideslip of the elastic tire 4 on the rear side increases due to the factor (1). E) Walking function In cross-country snow skiing, when running on a flat surface, the left and right skis are alternately advanced to advance.

In this case, for example, when the right ski is pushed forward, a load is applied to the right ski to kick the ground contacting surface to push the right ski forward.
It is common to apply non-slip wax (stop wax) to the center of the ski.

In this embodiment, the stop wheel 6 with the one-way clutch mechanism 5 plays the role of the stop wax.

The stop wheel 6 is not always grounded, but is grounded only when a load is applied, so that the walking function is also improved in this respect.

As described above, the present embodiment exhibits exactly the same function as the snow ski, and can be operated with the same feeling as the snow ski.

As described above, since the sensation on the land is exactly the same as that of the snow ski and the function of this embodiment is the same as that of the cross-country snow ski, the cross-country snow skier can run for the summer strengthening training. It is also the most suitable exercise equipment.

The above description is for the case where the elastic tire 4 does not float above the ground contacting surface, no matter how much the elastic tire 4 is tilted.
If the (edging board) is arranged, when the elastic tire 4 is tilted at a certain angle or more, only the edging portion comes into contact with the ground, and the elastic tire 4 does not come into contact with the ground, so that only the edging portion travels and side skidding does not occur. ..

[0060]

Since the present invention is constructed as described above, it becomes a running exercise tool which exhibits the same walking / rotating, sideslip / braking functions as snow cross-country skiing.
