Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skiing device and a roller ski, and more particularly, to a main body having a boarding surface on which a user rides, the main body being elongated in the front-rear direction and having a boarding surface on which a user rides. The present invention relates to a sliding tool and a roller ski provided with sliding means provided on both ends and supporting the main body and sliding in contact with a sliding surface. As a sliding device, there is a so-called skateboard or a mountain board in addition to a roller ski having a wheel unit as a sliding means.

[0002]

2. Description of the Related Art Roller skis are used for sliding on natural or artificial slopes (sliding surfaces) without snow. Conventionally, roller skis are provided to be long in the front-rear direction and have a boarding surface on which a user rides. And a plurality of rollers arranged at intervals in the longitudinal direction below the main body, or large wheels are provided at both ends in the front-rear direction of the main body, and a portion of the main body where the feet are placed The lower side has no wheels. Skis in which a crawler (caterpillar (registered trademark)) as an endless track device is used other than on snow provided as a sliding means have also been devised. This crawler-type ski is extremely excellent in straightness.

[0003] In these skis that are used on places other than on snow, the main body portion corresponding to the ski does not directly touch the slope, but has a flexibility similar to that of a normal snow ski. Due to the flexibility of the ski, it is possible to bend the sliding (running) direction of the ski during skiing. However, unlike snow skiing, it is difficult to bend the running direction of the ski, that is, it is difficult to steer because skidding cannot be suitably performed.

[0004] On the other hand, conventionally, a board called a mountain board, which fixes both feet on a single plate-shaped main body 10, has a basic mechanism shown in FIG.
That is, in the basic mechanism shown in FIG.
0) are fixedly provided at both ends in the front-rear direction, respectively, and when the boarding surface 12 of the board 10 is positioned parallel to the running surface, the axis 11 extends in the front-rear direction parallel to the running surface of the board 10. Steering shaft 2 tilted up and down
0, and the wheel units 30 respectively provided corresponding to the steering shafts 20 are directed in the front-rear direction when the riding surface 12 is positioned parallel to the running surface, and the riding surface 12 is moved in the left-right direction about the axis 11. The wheel unit 30 is moved about the steering shaft 20 so that the head is swung in the left-right direction when tilted.
And a shaft mounting portion 25 that is rotatably mounted on the shaft.

[0005] Then, the board 10 is always mounted on the boarding surface 1.
2 is supported by the wheel unit 30 via elastic members (e.g., coil springs) provided on the left and right so as to be positioned in a neutral state parallel to the running surface. In the basic mechanism of this mountain board, the user leans the board 10 by applying weight to either the left or right of the board 10, and the wheel unit 30 can swing the head in the direction in which the board 10 tilts. For example, when the board 10 is tilted to the left with respect to the traveling direction, the wheel unit 30 is turned to the left with respect to the traveling direction and shakes its head, and the traveling direction of the board 10 can be bent to the left. . For this reason, the running direction of the board 10 can be bent in the same manner as when the steering wheel is turned in an automobile.

[0006]

However, in the above-mentioned conventional mountain board, it is difficult to lean on the board 10 due to the structure of the human body, and the direction of travel of the board 10 must be changed. Difficult.
Therefore, there is a problem that it is difficult to glide while favorably curving in a well-balanced manner in both the left and right directions.

[0007] In the case of roller skiing, there is no mechanism in which the wheel unit 30 shakes the head.
In addition to the difficulty in changing the direction of travel, the structure of the human foot makes it easy to tilt the foot inward,
On the other hand, since it is difficult to incline outward, there is a problem that it is difficult to slide while keeping a well-balanced curve in both the left and right directions. That is, as shown in FIG. 12, the so-called squaring angle at which the skier tilts his or her foot with respect to the running surface in an attempt to rotate has a small α2 and a large α1. In other words, the angle of the outer squaring by the foot inside the rotating arc is easier to be smaller than the angle of the inner squaring by the foot outside the rotating arc, and if this goes too far, the left and right skis will be parallel. The skiers fall over because they are not aligned.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a sliding device and a roller ski capable of easily performing a curved run in a well-balanced manner in both right and left directions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments according to the present invention will be described below in detail with reference to the accompanying drawings. (First Embodiment) FIG. 1 is a perspective view schematically showing one embodiment (first embodiment) of a sliding implement according to the present invention. 2 is a plan view for explaining an operation state of the sliding implement according to the embodiment of FIG. 1. FIG. 2 (a) is a state in which the riding surface is positioned parallel to the sliding surface, and FIG. 2 (b) is a sliding state. Direction of travel (sliding direction)
Is in the direction of the arrow, the boarding surface is rotated leftward about the axis of the main body and tilted. FIG. 2 (c) shows the traveling direction (sliding direction) of the sliding implement as indicated by the arrow. When the direction is the direction, the boarding surface is rotated rightward about the axis of the main body and tilted. (Incidentally, the left and right inclination angles of the main body are 90 degrees, respectively, in order to facilitate understanding of the operation principle. However, in actual running, the left and right inclination angles are limited to about 45 degrees at the maximum. )

First, the components schematically shown in FIGS. 1 and 2 will be described. Reference numeral 10 denotes a main body, which is long in the front-rear direction and has a boarding surface 12 on which a user rides.
Numeral 30 denotes a wheel unit, which is provided at both ends in the front-rear direction of the main body 10 and is an example of a sliding means that supports the main body 10 and slides in contact with a sliding surface. Each wheel unit 30 is provided with a pair of wheels 34 that are rotatably mounted on the wheel support 32 around the axis of the wheel support 32. Note that the sliding means is not limited to the wheel unit 30 having the wheels 34 such as rollers and tires, and in some cases, a sled or a crawler (crawler device) may be used.

Reference numeral 20 denotes a steering shaft, which is fixed to at least one end of the main body 10 in the front-rear direction. In the present embodiment, the steering shafts extend at both ends in the front-rear direction of the main body 10 at a predetermined angle upward with respect to the upper surface (the riding surface 12) of the main body 10.
That is, when the boarding surface 12 is located parallel to the running surface,
Axial line 1 extending in the front-rear direction parallel to the running surface of main body 10
The main body 10 is fixed in a bar-like protruding state so as to be inclined in the vertical direction with respect to 1. In addition,
The rod-shaped projection shaft (insertion member) and the bearing-shaped insertion member that receives the rod-shaped projection shaft are relatively fitted to each other.
Is not a tangible thing, but can also be constituted by an inserted member into which an insertion member is fitted. That is,
In the present embodiment, the rod-shaped projection axis is formed on the main body 10, but the present invention is not limited to this. The rod-shaped projection axis is extended at a predetermined angle on the wheel support 32 of the wheel unit 30. The main body 10 may be provided with a cylindrical bearing rotatably receiving the rod-shaped projection shaft.
This also enables the wheel unit 30 to rotate about the steering shaft 20, and the wheel unit 30 can shake its head appropriately.

Reference numeral 25 denotes a shaft attachment portion, and each wheel unit 30 corresponding to each steering shaft 20 faces in the front-rear direction when the riding surface 12 is positioned parallel to the running surface.
Reference numeral 2 denotes a shaft mounting means on which the wheel unit 30 is rotatably mounted on the steering shaft 20 so that the wheel unit 30 is swung right and left around the axis 11 when tilted. In other words, the shaft attachment portion includes, for example, a bearing and includes the above-described insertion member (rod-like projection shaft) and a member to be inserted, and the insertion member and the member to be inserted include a steering shaft. It is provided at a predetermined inclination corresponding to the inclination of 20.

Reference numeral 26 denotes a steering shaft fixed portion, which functions as a swing asymmetry means for asymmetrically swinging the wheel unit 30 in the left-right direction. According to the steering shaft fixing portion 26, when the riding surface 12 is positioned parallel to the running surface, the steering shaft 20 is tilted up and down with respect to the axis 11 of the main body portion 10 and in one of the left and right directions. The steering shaft 20 is fixed to the main body 10 so that the steering shaft 20 is also inclined.

According to this, when the main body 10 rotates to one side around the axis 11, for example, as shown in FIG. 2B, the main body 10 is tilted to the left in the sliding direction of the arrow. The inclination in the vertical direction (elevation angle θ1, see FIG. 3) and the inclination in the horizontal direction (in the first embodiment, the oblique angle θ2 which is the rightward inclination in the state shown in FIG. 2A, see FIG. 3) are added. And the swing angle γ2 increases. Therefore, in this case, the glider becomes easy to bend. That is, the radius of rotation (counterclockwise) by the glider decreases. On the other hand, in the case of turning to the other side, for example, as shown in FIG. 2C, when the main body 10 is tilted to the right in the sliding direction of the arrow, the tilt in the vertical direction (elevation angle θ1, see FIG. 3) and the right and left Direction inclination (1st
In the embodiment, the oblique angle θ2, which is the rightward tilt in the state shown in FIG. 2A, acts so as to partially cancel each other, and the swing angle γ1 becomes small. Therefore, in this case, the glider becomes difficult to bend. That is, the rotation (clockwise) radius of the glider increases.

In the sliding implement according to the first embodiment, the swing of the wheel unit 30 can be suitably asymmetrical with a simple configuration in which the angle of the steering shaft 20 is also inclined in the left-right direction. When the skiing tool is used as a roller ski, for example, for the left foot, if the left foot is fixed on the boarding surface 12 so that the left foot is directed in the traveling direction of the arrow, even if the left foot is tilted inward, the swing angle is γ1 is small, and it is difficult to bend when sliding. On the other hand, when the left foot is tilted outward, the swing angle γ2 becomes large, and the configuration is easy to bend. In other words, this is opposite to the tendency of the human foot structure (body structure) and the center of gravity to be easily tilted inward and hardly tilted outward. For this reason, the characteristics of the roller ski according to the present embodiment and the characteristics of the human body structure and the like are canceled out and averaged, so that a ski having a good balance between left and right and capable of suitably carving can be obtained.

In other words, the asymmetry of the swing angle of the roller ski and the nature of the human body structure complement each other, so that the wheel unit 30 can be swung appropriately on both sides. This has the effect of making a well-balanced turn in both directions. In the case of the right foot, the foot may be fixed on the boarding surface 12 with the foot directed in the direction opposite to the arrow direction. In the first embodiment, both the front and rear wheel units 3
Although the function of shaking the head is provided for 0, the function is not limited to this, and a function of shaking the head may be provided for only one (usually the front wheel). This also makes it possible to suitably carry out carving during sliding by the sliding implement.

(Second Embodiment) Next, a roller ski (second embodiment) having a more specific configuration described above will be described.
This will be described in detail with reference to FIGS. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed description is omitted. The ski plate portion 10 is the main body portion that is provided to be long in the front-rear direction and has a boarding surface 12 that is an upper surface on which a user rides.

Each wheel unit 30 has a pair of wheels 34 which are always in contact with the slope and support the weight of the user (skier).
And a wheel support 32 that holds the wheel 34 rotatably. Thus, the wheel unit 30
By using the wheel support portion 32 and the pair of wheels 34 rotatably provided at both ends of the wheel support portion 32, a roller ski that can slide more stably can be obtained.

The steering shaft unit 25 is composed of the steering shaft 20 and the wheel support portion 32, connects the ski plate portion 10 and the wheel unit 30, and connects the wheel unit 30 to the steering shaft center 21 within a limited angle. The shaft attachment portion rotatably holds. According to the steering shaft unit 25, when the riding surface 12 of the ski portion 10 is positioned parallel to the running surface 40, the wheels 34 are in a neutral position in the left-right direction and are oriented in the front-rear direction so that they can slide straight. Then, when the boarding surface 12 is tilted while being rotated left and right about the axis 11, the wheel 34 operates to swing right and left in accordance with the operation.

As in the above-described embodiment, the steering shaft 20 is provided at both ends in the front-rear direction of the ski portion 10 at a predetermined angle upward with respect to the upper surface (riding surface 12) of the ski portion 10. (Elevation angle θ1) and is fixed via a steering shaft fixing portion 26 in a state of being inclined. That is,
When the riding surface 12 is positioned parallel to the running surface 40, the steering axis 21 viewed from the side of the ski 10 and the ski 1
The elevation angle θ1 which is the angle of intersection with the boarding surface 12 of 0 is set to a predetermined angle.

In the second embodiment, as described with reference to FIG. 1 and FIG.
When the riding surface 12 is positioned parallel to the running surface 40 in order to make the swinging of the wheel unit 30 in the left-right direction asymmetric, the steering shaft 20 moves in the left-right direction with respect to the axis 11 of the main body 10. One of them (in this embodiment, the left side in the sliding direction of the arrow) is also provided at a predetermined angle (oblique angle θ2). That is, the boarding surface 12 is
Is positioned parallel to the steering axis 21 as viewed from above and the oblique angle θ2, which is the angle at which the steering axis 21 intersects with the axis 11 of the ski 10, is set to a predetermined angle. I have.

Since the steering shaft 20 and the steering shaft unit 25 are set as described above, the wheel unit 30
Turns around the axis of the steering shaft 20 in accordance with the squaring angle of the ski, and the ski 34 is supported by the wheels 34 always in contact with the sliding surface 40 (slope). Then, by the effect of the steering shaft 20 appropriately arranged as described above,
With the inclination in the left-right direction (roller ski squaring) around the axis 11 of the ski portion 10, the wheels 34 tilt in the left-right direction with respect to the axis 11 of the ski portion 10,
Change the direction of skiing (roller skiing). That is, by the action of the steering shaft 20 and the like, it is possible to obtain the swing angles γ1 and γ2, which are the inclination angles in the left and right directions with respect to the axis when the roller ski is viewed from above. Can be changed to As described above, the angular arrangement of the steering shaft 20 is an important factor that determines the correlation between the squaring angles α1 and α2 of the roller ski and the swing angles γ1 and γ2 of the wheels, and derives skiing performance.

According to the second embodiment, as described in the first embodiment, the steering shaft 20 is moved to the predetermined elevation angle θ.
1 and the oblique angle θ2, the swing of the wheel 34 becomes asymmetric. That is, when the ski part 10 is rotated to one side around the axis 11, the elevation angle θ1 and the oblique angle θ2 are:
Acting to add, the swing angle γ2 increases as shown in FIG. Therefore, in this case, the roller ski is easily bent. That is, as shown in FIG.
When the arrow is in the sliding direction, the rotation (clockwise) radius of the roller ski becomes smaller. On the other hand, the ski part 10
Is rotated to the other side, the elevation angle θ1 and the oblique angle θ2 act to partially cancel each other, and the swing angle γ1 decreases. Therefore, in this case, the roller ski becomes difficult to bend. That is, the radius of rotation (counterclockwise) by the glider increases.

In the second embodiment, the elevation angle .theta.1 and the oblique angle .theta.2 are specifically set, and the inclination angles in the left and right directions about the axis of the ski 10 (roller ski squaring angles α1, α2). ) And the changes in the swing angles γ1 and γ2 will be described with reference to the graph of FIG. In the graph of FIG. 5, the inclination of both the elevation angle θ1 and the oblique angle θ2 is set to 15 degrees, and the ski squaring angle α ( α1, α2), and the swing angle γ (γ1, γ2) of the wheel is set on the Y axis. A is the ski squaring angle α1 and the wheel swing angle in the embodiment of FIG. 3 (second embodiment) in the case where the ski 10 is tilted and angled to the opposite side to the state of FIG. γ1 (FIG. 2 (C)
Reference). B shows the ski part 1 in the state of FIG. 4 in the embodiment of FIG. 3 (second embodiment).
The relationship between the squaring angle α2 of the ski and the swing angle γ2 of the wheels when the squaring is performed by inclining 0 is shown.
As is clear from this graph, the setting of the steering axis allows the swing angle of the wheel unit to be suitably asymmetrical in the left-right direction, and the preferred effects described above are achieved.

In the second embodiment described above, the steering shaft 20
Has been described as being fixed at a predetermined angle, the fixed angle of the steering shaft 20 may be set as appropriate according to conditions such as the body structure of the user or the skill level. If an angle adjusting mechanism is provided so that the angle of the steering shaft 20 can be appropriately adjusted according to the conditions of the user, it is possible to obtain a roller ski capable of performing a suitable operation according to the user's preference. it can.

Next, another embodiment according to the present invention will be described with reference to FIGS. (Third Embodiment) FIG. 6 is an explanatory view for explaining a third embodiment according to the present invention. FIG. 6 (a) shows a state in which the riding surface is positioned parallel to the sliding surface 40 (neutral state). FIG. 6B is a partial plan view, and FIG. FIG. 7 is a side view of the second embodiment. FIG. 8 shows that when the direction of the rider along the axis of the ski portion of the third embodiment is the direction of the arrow, the riding surface is rotated leftward about the axis. FIG. 4 is an explanatory view showing a tilted state. FIG. 8A is a plan view of the main part, and FIG. 8B is a front view of the main part. FIG. 9 shows that when the direction of the rider along the axis of the ski portion of the third embodiment is the direction of the arrow, the riding surface is rotated rightward about the axis. FIG. 4 is an explanatory view showing a tilted state. FIG. 9A is a plan view of the main part, and FIG. 9B is a front view of the main part. The first
The same components as those of the embodiment and the second embodiment are denoted by the same reference numerals, and the detailed description is omitted.

Reference numeral 28 denotes a shaft fixing portion, and the wheel unit 3
This is means for assimilating the head swing in the left-right direction of 0. According to the shaft attachment fixing portion 28, the shaft-mounting portion 28 is provided continuously in the form of a shaft at the base portion side of the steering shaft 20,
A root shaft portion 22 extending in parallel to 1 is fixed to a ski portion 10 as a main body portion so as to be freely rotatable around an axis 11 in a predetermined angle range. In this embodiment, the ski portion 1
The base shaft portion 22 is rotatably inserted around a shaft center through a bearing portion 13 provided at the end of the “0”, and is rotated by a bent portion 24 and stopper portions 14 and 16 described in detail below. Are being regulated.

According to the third embodiment having the shaft attachment fixing portion 28, the riding surface 12 is moved from the neutral state shown in FIG. 6 to the riding center 12 as shown in FIG. When the steering shaft 20 is rotated leftward about the line 11, the steering shaft 20 is tilted leftward with the rotation. This is the root shaft 22
However, when the boarding surface 12 rotates to the left, the engagement state is established so as to rotate in conjunction therewith. That is, in the present embodiment, the L-shaped bent portion 2 that is the engagement portion of the root shaft portion 22 is used.
4 is engaged with one of the stopper portions 14 (projections on the right side in the drawing), which are engaged portions formed by projecting on the ski plate portion 10, and the steering is performed via the base shaft portion 22. The shaft 20 rotates. In other words, one stopper 1
4 presses the bending portion 24 to push the steering shaft 2 through the base shaft portion 22.
0 leans to the left. As a result, the wheel unit 30 is turned so as to swing to the left. For this reason, the roller ski can be suitably rotated leftward during the skiing. Note that the neutral state in FIG. 6 means that the wheel unit 30 and the ski plate 10 are located straight, and the roller ski is in a straight-ahead state.

On the other hand, from the neutral state shown in FIG.
When the occupant surface 12 is turned to the right around the axis 11 as shown in FIG. 9 in the direction in which the occupant faces as indicated by the arrow, when the turning angle is within a predetermined range. , The steering shaft 20 does not tilt. This is because when the base shaft 22 rotates to the right of the riding surface 12, the play portion 18 causes the ski portion 1 in a predetermined section (a tilt angle range within a certain range) by the play portion 18.
It does not rotate with 0. Therefore, the steering shaft 20 is inclined in the up-down direction, but is not inclined in the left-right direction, and is in the neutral position as in the state of FIG. That is, turning the boarding surface 12 rightward within a predetermined angle range does not affect the swing of the wheel unit 30. Thereby, the wheel unit 30 is located straight like the state of FIG. 6, and the straight traveling state of the roller ski is maintained.

When the riding surface 12 is further turned to the right, the other stopper 16 (the left projection in the drawing), which is the engaged portion formed by projecting on the ski plate 10, is brought into contact with the ski. The engaged state is established, and the steering shaft 20 tilts to the right. According to this, the wheel unit 30 is rotated so as to swing the head to the right. Therefore, the wheel unit 3 to the right
In order to make a zero swing, it is necessary to tilt the riding surface 12 more or to use another maneuvering method. That is, the swing of the wheel unit 30 is suitably asymmetric with a simple configuration. In addition, since it is asymmetric as described above, in the third embodiment of FIGS. 6 to 9, if the arrow is the traveling direction, it can be suitably used for the left foot of the roller ski. The play portion 18 is a gap between the two stopper portions 14 and 16, and the size of the play portion 18 can be adjusted to suit the user's preference by appropriately setting its size.

(Fourth Embodiment) FIG. 10 shows a fourth embodiment according to the present invention.
FIG. 14 is a side view for explaining the third embodiment, which operates exactly the same as the third embodiment, except that the structure for fixing the steering shaft 20 to the ski portion 10 is reversed. different. That is, in the third embodiment, the bearing portion 13 is provided on the ski plate portion 10 side, and the root shaft portion 22 fitted to the bearing portion 13 is provided continuously to the steering shaft 20.
In the fourth embodiment, the male-female relationship is reversed. That is, in the fourth embodiment, the root axis 11 parallel to the axis 11
A shaft portion 22a having a shaft center as a shaft center is fixedly provided on the ski plate portion 10 side, and the bearing portion 1 for bearing the shaft portion shaft portion 22a is provided.
3 a is provided continuously on the root side of the steering shaft 20.
As described above, the shaft portion and the bearing portion are relative to each other with respect to one axis line, and even if the members fixed to each other are reversed, there is no change in the function of being able to pivotally attach to each other. In this regard, the relationship between the steering shaft 20 and the wheel support 32 is exactly the same. The operation function of the fourth embodiment is the same as that of the third embodiment, and the description is omitted.

In the above embodiments, roller skis have been mainly described. However, the present invention is not limited to this, and can be suitably applied to other sliding devices, for example, skateboards or mountain boards. Of course. that's all,
Although the present invention has been described in various embodiments with reference to preferred embodiments, the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. It is.

[0040]

According to the present invention, it is possible to easily make a well-balanced and suitable curve in both the left and right directions by means of the asymmetrical swinging means for asymmetrically swinging the sliding means in the left-right direction. Works well.
