Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a new sports equipment. Some parts of the invention are also applicable to other technical fields.

[0002]

[Problems to be Solved by the Invention] Even if there is no snow, it is possible to enjoy a sensation of movement similar to skiing, and the stock is obstructive, so it is unnecessary. It is equipped with a brake that works well for safety and has good operability. In order to enable high-speed cornering such as road racing, it has a structure with less strain on the foot, a rational frame structure with low air resistance and high rigidity, a steering mechanism for accurate steering control, and further, it has no air pollution or noise. It was a challenge to develop a tool for demonstrating so-called futuristic vivid sports, which is equipped with a solar cell-powered drive system that enables universal specifications.

[0003]

[Means for Solving Problems] As mentioned above, it was not that there were originally problems to be solved or existing technologies to be improved, and construction of deep charm as a new sport and establishment of originality in taste. And so on, mental performance is also required, so we aimed to clear the target problem by repeating trial production and testing. The specific means, design, and details of the invention will be described below.

[0004]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is paired for the left foot and the right foot, and each frame drives shoes, front wheels and its steering mechanism, rear wheels and its braking mechanism, and also rear wheels. It contains the drive mechanism of.

First, regarding the wheels, tread members that can be replaced by bolts and nuts are attached to the outer circumference of an engineering plastic wheel rim having ball bearings on the left and right. This form is economical. The overall width of the tread should be about the width of the player's foot or slightly wider. The profile is arcuate, and since there is a point of sole attachment force against the player's shoes that is below this center point, the tread portion has a spilling effect, which results in the player standing upright or going straight. This frees you from the task of focusing your ankle and straining your muscles. In the case of a profile in which the curvature of the arc is not constant and has a plurality of center points, the foot sole attachment point is placed below the lowest center point. The wheel diameter will be determined by the weight of the player, the layout of the course being run, and other factors. The tread compound will be examined based on the material of the running course, various numerical values, and the relationship with the course layout. The tread pattern is similar. Since it is a sport that assumes fairly high speeds, we would like to set up a special course and develop special wear with materials that absorb shock well so that damage to the player in the event of a fall is small.

As for the wheel bases of the front and rear wheels, the longer the wheel base, the more comfortable the running feeling can be obtained within a range that does not make it difficult to handle.
Further, the slip characteristics and slide characteristics of the front and rear wheels are stable even in high-speed cornering.

Steering is performed on the front wheels. This is easier to do for tuning the so-called steering characteristics. Simultaneous front and rear wheel steering will also be effective for further high-speed cornering. Two front axes or two rear axes are also conceivable.

There are two types of steering methods, both of which are foot operation methods that do not require a steering wheel. First, the vertical Z-axis, which is common to the frame and shoes, is set, and the shoes are attached to the frame by a rotary bearing or the like so as to be rotatable about the Z-axis. Then, the player's foot Z-axis rotation operation is transmitted from the shoes to the front wheel mounting member by a transmission mechanism using a rod, a gear train, or the like, and a steering angle is given to the front wheels to turn left and right. The position of the rotary shaft is more suitable than the center of the entire length of the shoe. Ergonomically, it is good to tilt the axis slightly forward. The front wheel mounting member is rotatable left and right by an annular rotary bearing, and the annular rotary bearing support is fixed to the frame. The relationship between the operating angle of the foot and the steering angle of the front wheels may be equal, but if the steering angle is amplified to give a small turning angle, it will be easier to turn around. It is better to be able to adjust the steering ratio in consideration of the course layout and wheel base. Also,
The foot operation direction and the steering direction can be used in either forward or reverse directions. The difference is a slight change in player form and center of gravity.

Another steering mechanism will be described by its operation on a horizontal road surface. If the X axis is the straight traveling direction of the main body on a horizontal road surface, the X of the road surface and that of the frame
The angle θ formed by the plane consisting of the Z-axis is 0 degrees when the body stands upright on the road surface, but this angle is used to operate the foot around the X-axis in the anteroposterior direction of the foot to move the X-axis to the frame. The θ angle is given to the frame through the shoes that lock the circumference. The front wheel mounting member is rotatable left and right by an annular rotary bearing mounted on the frame. The layout is such that the central axis of the front wheel is in front of the axle of the front wheel on the frame XZ plane, and the ground contact point exists in front of the front wheel ground contact point. When θ angle is given to the frame by the player's foot operation at rest, the load perpendicular to the road surface where the player load taken by the front wheels and the main body load are combined is the vertical reaction force from the front wheel tread force point on the road surface. As it acts toward the point farthest from the road surface of the ring of the annular rotary bearing inclined by θ angle, the front wheel mounting member, which is the path of the reaction force, makes a rotary motion at this time, so that a steering angle is generated at the front wheel. This action is more than the sum of the rotational resistance of the ring-shaped rotary bearing and the frictional force acting on the front wheel ground contact surface, rather than the sum of the reaction force of the load of the player and the main body of the ring of the ring-shaped rotary bearing at the action center point of the ring. This is because the tangential component force far outweighs the force or torque that causes the front wheel mounting member to rotate. For the annular rotary bearing, a combination of light alloy and engineering plastic having a low friction coefficient is suitable. In addition, a part of the ring may be cut and omitted due to restrictions on the mounting space or the like. In actual cornering, speed,
Both corner radii change every moment. Naturally, in that case, the centrifugal force acting on the player and the main body also largely changes, and the opposing centripetal force must obtain most of it as the cornering power of the front and rear wheels due to the proper steering angle of the front wheels and its holding. Since the total number of wheels used is four on the left and right, it depends on the position of the center of gravity, but the required centripetal force per wheel is 4
You will be responsible for one part. The rear wheels are rigid, so there is no problem. In one scene of cornering, the torque around the central axis in which the front wheels are twisted in the steering angle 0 ° direction due to the influence of centrifugal force and the front wheel mounting member in the reverse rotation direction due to the tangential component of the action center point of the ring. This means that the twisted torque around the central axis is balanced, and it is important that the steering holding force of all the wheels be proportionally increased as the θ angle increases. This is because if there is no steering wheel, the proper steering angle, that is, the corner radius desired by the player will be controlled by the steering power. At the same corner radius, as the speed increases, the θ angle increases, which is preferable as the direction of change of the center of gravity between the player and the left and right bodies. Become. To increase the steering holding force, increase the diameter of the ring of the annular rotary bearing.Increase the inclination of the annulus in the direction of increasing the forward tilt angle of the central axis. The angle change, that is, the steering ratio tends to decrease, which contributes to more accurate steering control. Shortening the distance between the center axis and the front wheel ground contact point (however, this distance depends on the front wheel tread width and tread profile etc.) May fluctuate randomly when the θ angle and the rudder angle change, so it is important to reduce the fluctuation of the distance for straight maneuverability). As a result, accurate cornering with a better steering response becomes possible in combination with an increase in the tangential component force of the ring at the action center point of the ring as the θ angle increases. The angle of inclination of the annular rotary bearing should be adjustable according to the skill of the player. Also, if the maximum steering torque of the front wheels is arbitrarily tuned within the range where the maximum cornering power of the front and rear wheels still has a margin, the breakout of the front and rear wheels does not occur and slip and fall safety does not occur. This allows for excellent cornering. In addition,
The influence of the weight and the center of gravity of the rotating body around the central axis, which is located near the central axis and includes the front wheel and its mounting member, on the steering mechanism is insignificant.

By applying this steering mechanism, it may be possible to realize a motorcycle that does not easily slip and fall. Alternatively, it is possible to fabricate an infant riding device that runs over a frame, and use it for steering a competition wheelchair. It is also possible to connect the left and right frames with a link or the like so as to give the same θ angle to the left and right simultaneously. These two types of steering mechanisms can function without contradiction even if they are used in combination.

The steering mechanism that steers by giving the θ angle to the frame can also be applied as a front steering mechanism of a traveling tool on ice and snow. In this case, the front wheels are replaced with sleds or the like.
For snow use, increase the size to prevent the sinking of the sled.
The shape of the central part such as the sled shall be the scale of the bowl-shaped tread surface curved surface near the road surface of the front wheel in the stopped state. The other components, layout, and operating principle are the same as in the case of using wheels, and the front wheel ground contact point, more specifically, the force center point is the force center point near the sled central portion. The rear wheels are of course replaced with sleds, spiked tires, tracks, etc. for running on ice and snow. Wear it on your left and right legs to make it look like skiing or skating, and if you use only one of them to ride sideways, it will look like snowboarding. If you put a seat on the frame and straddle it, it becomes a sliding tool similar to a bicycle. A steering handle may be provided to assist the θ-angle steering. Of course, one side may be used for the front steering section of a snow motorcycle, and the snowmobiles may be arranged in parallel on the left and right sides, and the left and right frames may be connected by a link or the like to give the same θ angle in the left and right directions at the same time.

The brake is the most important from the viewpoint of ensuring the safety of the player, and a brake mechanism having a good operability and a brake actuator having a simple structure were devised. During braking, the player tends to fall forward due to his own inertia. Therefore, the brake is operated by the operation of lowering the heel around the Y axis of the foot with respect to the frame. The center of gravity of the player who has moved to the rear when the brake is operated is pushed back by the inertia due to the inertia of the brake and is offset well. This works really well. It is possible to operate the brakes even if you step on it, but it is difficult to maintain your position. The operation of pressing the heel is transmitted to a brake actuator by a rod or the like, and a brake pad fixed to a caliper arm is pressed against a brake rotor fixed to a rear wheel to perform braking. This brake mechanism is also suitable as a brake mechanism for other traveling equipment in which shoes are located between the front and rear wheels.

Further, a screw-type mechanical disc brake actuator was devised for the downhill two-wheeled vehicle. The left and right caliper arms to which the brake pads are fixed are partially threaded in the reciprocating direction of the caliper arms as driven screw nuts. The screw directions of the left and right calipers are opposite. Then, it is combined with one screw bolt on the drive side that is threaded corresponding to this screw part. To operate the heel, rotate the drive-side screw bolt with a rod or the like, and in conjunction with this, the left and right caliper arms that are driven-side screw nuts reciprocate in the screw axis direction, and the brake pads fixed to the caliper arm brake. It is braked or released by being pressed against or separated from the rotor. Light alloys are suitable for the brake rotor that is fixed to the rear wheels in terms of weight. If it is a wheel rim made of high heat resistant engineering plastic, it may be directly attached by bolting. The caliper arm is also light alloy. The brake rotor may be fixed to both side surfaces of the rear wheel and the left and right caliper arms may be sandwiched from both sides, or the brake rotor may be extended to one side surface of the rear wheel and sandwiched between the left and right caliper arms. The left and right caliper arms are naturally equipped with torque rods or bars. It is preferable to equip the left and right bodies with the brake mechanism and to operate them simultaneously, because the braking ability will be higher and the balance of the player's posture will be better. In addition, by braking the rear wheels, so-called braking drift technique can be easily performed. Depending on the usage conditions such as the course layout, it is naturally possible to add front wheel brakes.

Two-wheeled vehicles for downhill are classified into two types depending on their acceleration and driving methods. One is to use gravity as the basis of driving, and equips the rear wheels with a one-way clutch that enables vertical displacement in the X-axis during sudden acceleration or on flat roads. Of course, skiing and skating are also possible for the familiar sideways. The rear wheel is connected to a one-way clutch such as a shell type roller clutch or a ball silent ratchet after decelerating the rear wheel rotation speed by a gear train or a cocked belt. At this time, the forward direction by gravity is the overrun direction, and the vertical acceleration is the lock direction. This makes climbing easier. By decelerating and using the one-way clutch, its performance is maintained well and running resistance is reduced. With this specification, an increase in the weight of the main body is suppressed and it becomes a competitive sports form.

The other is that, in addition to the use of gravity,
It is a type that can accelerate, run, and climb slopes with electric energy using a dynamo, battery, and drive motor mounted on the frame. The operation of turning the foot around the Y-axis with respect to the frame is changed to rotational movement by a screw or the like, and the DC dynamo is rotated after appropriately increasing the speed by a gear train or the like. The generated power is sent to the driving DC motor connected to the rear wheels, and the vehicle travels accordingly. With regard to the work amount of manipulating the foot in the stepping direction, a maximum of about 40 watts has been confirmed by experiments. Attach the driving drive screw nut to the tip of the shoe, and pass the Y-axis rotary shaft common to the frame and the shoe so that it can be stroked downward. The position of the rotary shaft is suitably located rearward from the center of the shoe. The change in the posture of the player during the acceleration operation is canceled by the acceleration G, which is preferable as in the braking operation.
It is desirable that the toe force is transmitted to the DC dynamo with a small loss, and there may be a more efficient transmission method such as a cogged belt, reel, hydraulic pressure, or pneumatic pressure. The advantage of this acceleration method is that even while cornering, the four wheels can be grounded and the cornering power can be secured while speeding up, and the use of an electric motor provides an automatic transmission effect. The point is that acceleration from any initial speed is possible. This drive mechanism is also suitable as a drive mechanism for other traveling equipment in which shoes are located between the front and rear wheels.

In order to obtain a larger acceleration force and driving force, a battery mounted on the frame is driven by an auxiliary power controller composed of a dynamo output sensor, a power transistor, a custom IC, etc., based on the output of the DC dynamo. Driving DC as auxiliary power while adjusting battery output
Supply in parallel to the motor. Acceleration can be increased proportionally to the player's toe pressure, which gives a natural sense of operation. At present, a lithium ion battery pack is suitable as a battery in terms of storage capacity, weight, cost and the like. A print motor or the like is suitable for the driving DC motor in terms of various performances and dimensions. By the way, when the rear wheel tread diameter is 15 cm, the rear wheel rotation speed at 100 km / h is about 3500 rpm, and the rear wheel and the driving DC motor can be directly connected. The DC dynamo may be omitted, and the power supply controller may be operated by a toad operation to adjust the driving force. Further, if a regenerative braking circuit that interlocks with the braking operation is provided during braking to make the driving DC motor a dynamo, both braking performance and reliability are improved, and the generated power can be collected in a battery.

Since the frame is constantly subjected to bending and twisting in the X-axis direction and vibrations of a wide range of frequencies, a highly rational monocoque is suitable, and a cylindrical shape is particularly preferable from the viewpoint of cost. The same applies to polygonal cylinders. The front and rear ends are designed with air rectification in mind. The tubular frame is useful because it allows you to obtain deep bank angles. In the case of metal, the material is inevitably encountered with metal fatigue, and therefore many are suitable for engineering plastics, fiber mixed engineering plastics, carbon FRP, glass FRP and other so-called composite materials.
And accent and brake in the overall design,
In order to cool the motor, battery, etc., and at the same time to measure the weight, holes are made in various places in the frame where there is no problem in strength. Alternatively, a frame with a cage structure that combines small diameter light alloy pipes seems to be good.

The shoes can be implemented so that the invention can be carried out without the need for an extreme discussion. However, if the usage scene of the motorcycle for downhill is taken into consideration, the shoes can be detached. It is good that it can be easily detached from the main body with one touch. In addition, in order to prevent accidents such as a sprain of the foot in the event of a fall, a safety device that automatically separates the main body from the shoes due to an abnormal direction and size G is incorporated in the shoe wear.

Although the above-mentioned battery charging method is used, it is also possible to charge the battery from the power line as a matter of course, and to install a solar module on the upper surface of the cylindrical frame so that the battery is constantly charged during the day. Another option would be to prepare a foldable solar module separately and sunbathe in the rest zone near the running course, or wait for it to be charged while having fun even with a bird watch. This means that no matter where you play in the world, you can use one specification.
The battery combined type has a high grade climbing ability and can be used in a cross-country manner. Unlike so-called motor sports, sports using this downhill motorcycle do not cause air pollution and the running sound is quiet, so if you pay attention to the location of the course, material of the course, management, etc. Coexistence with nature will surely be possible. In Japan, there are many sloping areas or even areas that are suffering from depopulation, and it seems that there are many suitable places for setting up courses. It is not bad to have a hilly area near the city. Alternatively, it may be possible to operate as a special sports menu at domestic and overseas resorts. If the speed range is limited, it would be suitable for amusement parks. Even on flat terrain, if you use a circuit course layout for motor sports, the fun will double. Although it will be possible to acquire new sporting properties even with existing roller skates. Complicated sports with various rules such as ball games are far from releasing the mood, and in this motorcycle for downhill, there is only good manners to protect the safety of each player. In order to prevent cross-collision accidents between players, the existing ski resort layout will not be adopted. The course design will be one of the motorsport circuits that is cut and stretched to a slope. It's a good idea to run several of these in parallel and set up lane change zones here and there. This downhill two-wheeled vehicle can perform full braking and sudden acceleration, so you can play with a variety of changes such as speed, corner radius, ups and downs by installing a hairpin next to the straight. Both sides of the course will be planted with the function of a safety zone. Seasonal flowers mark the corners and lane change zones. This motorcycle for downhill is aimed at a refreshing new sport that has never existed before.
