Abstract

PURPOSE:To obtain the running exercise implement having the same characteristic as a snow ski by providing an oscillating tire for oscillating in the direction being orthogonal to the running direction in the front part and the rear part of a base plate. CONSTITUTION:In the front part and the rear part of a slender base plate 2 provided with a foot fixing part 1, a wheel 3 is respectively provided so as to be freely rotatable in the base plate length direction, and in a suitable part of the base plate 2, a stop wheel 6 is provided with a one-way clutch mechanism for obstructing a retreat running/ rotation in a suitable part of the base plate 2 so that an advance running/rotation can be executed freely in the same direction as the wheel 3. Also, a distance between the lower edge of the stop wheel 6 and the ground surface in a normal state is set to a prescribed distance L, and also, when load works on the base plate 2, it is set so that the stop wheel 6 is grounded. In this case, as for one or both of the wheels 3 of the front part and the rear part, an oscillating tire 30 whose ground outside peripheral part oscillates in the direction being orthogonal to the running direction is adopted. Only in the case load works on the base plate 2, the stop wheel 6 is grounded, therefore, this implement can be operated in all the same sensation as a snow ski.

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

[0007] Conventional products generally have a rotating body attached to a substrate, a frame, etc., but rollers, wheels, caterpillars and the like 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, the use conditions such as rollers and wheels for cross-country use are regulated due to the phenomenon as described above, and especially when used on a downhill, the braking function is insufficient and the rotation function is 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, snow skis produce various performances, functions, and effects by changing the load on the ski (load by the weight of the skier, weight extraction, shift of the center of gravity) and the action of the ski edge (edging operation). 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, the conventional products cannot perform the same running because the characteristics of the snow ski cannot be exhibited. As a result, in the present situation, there is no running exercise equipment that can be played with the same feeling as the snow ski.

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 tool that exhibits characteristics completely equivalent to those of snow skis, especially country snow skis.

[0014]

The gist of the present invention will be described with reference to the accompanying drawings.

Wheels 3 are rotatably provided in the front and rear portions of an elongated base plate 2 provided with a foot fixing portion 1 in the lengthwise direction of the base plate, and a one-way clutch mechanism 5 for preventing backward traveling rotation is installed in an appropriate position of the base plate 2. The stop wheel 6 is provided so as to be able to travel forward and rotate in the same direction as the wheel 3, and the stop wheel 6 in a normal state is provided.
A running exercise tool in which the distance between the lower edge and the ground contact surface is set to a predetermined distance L, and the stop wheel 6 is set to contact the ground when a load is applied to the substrate 2, and the front and rear wheels 3 The present invention relates to a traveling exercise tool characterized in that one or both of which employs a swing tire 30 in which a ground contact outer peripheral portion swings in a direction orthogonal to the traveling direction.

[0016]

[Function] The stop wheel 6 is not always grounded, and the substrate 2
Since the stop wheel 6 comes into contact with the ground only when a load is applied to the vehicle, it can be operated with the same feeling as a snow ski.
Further, since the rocking tire 30 is present, it is possible to travel with movement in a direction orthogonal to the traveling direction.

[0017]

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 5 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 board 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.

A rocking tire 30 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 rocking tire 30 will be described with reference to FIGS.

A support member 38 is rotatably mounted on the shaft 36 fixed to the front and rear wheel support plates 8 via a bearing 37, and a curved groove 39 is formed on the outer periphery of the support member 38. , A plurality of tire members 41 having a curved fitting portion 40 projecting from the base portion which is fitted exactly in the curved concave groove 39, and the supporting member 38 by fitting the curved fitting portion 40 into the curved concave groove 39. A plurality of tire members 41 are arranged side by side at equal intervals on the outside of the.

An elastic member 42 is attached to the tip of the tire member 41, and the elastic member 42 is also interposed between the cover member 43 provided on the support member 38 and the curved fitting portion 40. There is.

Therefore, the tire member 41 swings in the direction orthogonal to the rotation direction of the support member 38 (left-right direction in FIG. 3).

Reference numeral 35 is a notch for allowing the rocking of the tire member 41.

The stop wheel 6 has the following structure as shown in FIG. 4 and FIG. 5, and the wheel 3 (swing tire 30) with respect to the ground contact surface.
A shaft 22 is installed on a stop wheel mounting plate 21 which is arranged 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.

For snow skis (including both alpine and cross-country skis) a) downhill function, b) skid function,
C) Braking function and D) Rotation function are the most important functions.
In addition, e-walking function is also important for cross-country snow skiing. Since the present embodiment has the above-mentioned configuration, it sufficiently exhibits the above-mentioned 5 functions.

A) Downhill function Straight downhill When the present embodiment is held in front of the fall line of the slope, the rocking tire 30 rotates, and in the present embodiment, the vehicle runs straight forward 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 obliquely held with respect to the fall line and the vehicle travels straight forward (see FIG. 6), the pitch of the rocking tires 30 on the ground swings in a direction orthogonal to the running direction, The entire portion of this embodiment except for the ground contact portion laterally moves by the amount of the swing. With the rotation of the rocking tire 30, the next pitch comes into contact with the rocking tire 30, and the rocking tire 30 also rocks and moves laterally. As a result of this, in this embodiment, the skiing is accompanied by skidding (slippage in the fall line direction) (see FIG. 7).

At this time, if the load for swinging the pitch of the rocking tire 30 on the ground does not act because the slope of the slope is small or there is almost no inclination of this embodiment with respect to the ground contact surface, In the embodiment, the skiing is not accompanied by skidding (see FIG. 6).

(B) Side slip function This embodiment is held at a right angle to the fall line on the slope to bring it into a stopped state. At this time, the grounding pitch of the rocking tire 30 rocks, and the center of gravity is closer to the fall line than the center of the grounding pitch (see FIG. 8). From the stopped state, when the present embodiment is run before or after (when the rocking tire 30 is rotated), it is said that the next pitch is grounding and rocking, and the next pitch is grounding and rocking. With the continuous operation, in the present embodiment, the skid of the slope starts downward (see FIG. 9).

C) Braking function Standing on a flat surface When standing vertically on a flat surface, the front and rear rocking tires 30 are almost evenly loaded (the distribution ratio may be slightly different depending on the shoe attachment position). Therefore, this embodiment is stable.

Stopping on a slope Hold this embodiment on the left and right toward the fall line of the slope in an inverted V shape (the slope lower side is narrower and the upper side is wider) and tilted inward,
A uniform load is applied to the left and right (a force is applied to the left foot to the left and a right foot to the right so as to push this embodiment outward), and the robot is stopped on the slope (see FIG. 10).

At this time, in the present embodiment on the right side, 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 pitch of the rocking tire 30 on the ground is rocking.

Sliding from a stop on a slope From the above stopped state, when the opening angle in an inverted V shape 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 rocking tire 30 (right side to the lower left of the slope, left side to the lower right of the slope) The balance is broken and the rocking tire 30 starts to rotate.

When each pitch of the rocking tire 30 comes into contact with the ground, that part rocks. Therefore, by the running of the rocking tire 30 and the lateral movement of each pitch, the present embodiment becomes a skid-side running. .

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 rocking tire 30 is increased. Is weakened, and the grounding pitch is the maximum swing, and the resistance in the lateral direction (the lateral direction is as shown in FIG. 11 when viewed from this embodiment, but the diagonal as shown in FIG. 12 when viewed from the traveling direction). (Backward direction) increases, and the run is gradually braked.

D) Rotational function In the state where the fall line described in c) is sliding with the inverted V-shape, the load of either one of the left and right embodiments is reduced or the load of either one is increased. Then, since the force on the side having a relatively large load advances in the rotational direction of the rocking tire 30, the rotational movement starts to the side having a small load (see FIG. 13). This is because the larger the load is, the larger the force is decomposed downward along the slope.

At this time, it is the player's heel push-out motion and the forward / backward motion that the player turns in an arc without straightly sliding down the slope (the side where the load is small) (see FIG. 14). This is because the amount of sideslip of the rear rocking tire 30 increases due to factors such as the load distribution of the rocking tire 30 and the rocking properties of the front and rear rocking tires 30. 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 grounding surface to push the right ski forward, but in order to increase the kicking force,
Wax that does not slip on the center of the ski (stop wax)
Is generally applied.

In this embodiment, the stop wheel 6 with the one-way clutch mechanism 5 serves as 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 functions 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 summer strength training. It is also the most suitable exercise equipment.

The above description is for the case where the tire member 41 (elastic member 42) does not float from the ground contact surface, no matter how much the rocking tire 30 is tilted. Edging board), if the rocking tire 30 is tilted by a certain angle or more, only the edging portion comes into contact with the ground, and the tire member 41 does not come into contact with the ground, so that only the edging portion will travel, and skidding will not occur. .

[0051]

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.
