The present invention relates to a cubing simulation device that enables realistic motion reproduction

Modern people are exposed to various foods due to excessive intake of food and absolute lack of exercise and stress. Recently, with increasing interest in health, various exercise equipments that can exercise indoors have been released.

Such indoor exercise equipment includes a variety of fitness equipment, such as a running machine (running machine), indoor cycle (Cycle), a rowing machine (rowing machine), and can be divided into uses for aerobic exercise or strength training.

However, most conventional indoor exercise equipment is not only limited to the point space, it is not easy to move and store, and in particular, as it is manufactured for the purpose of a specific exercise effect, there is a lack of interest for the user.

For example, in the case of the treadmill, the user runs boring while looking at the wall or mirror, and in the case of the indoor cycle, the user must continue the monotonous motion to obtain the exercise effect because the pedal is performed while looking at the wall or the mirror. Therefore, as interest is halved, it was difficult to lead to continuous movement.

In order to solve this drawback, a system has been proposed in which a large screen is installed in front of a treadmill or indoor cycle and an audiovisual device is installed to allow a user to feel as if they are actually running or driving. Behavioral change does not occur and simply relies on audio-visual, which has the disadvantage of limiting the exercise effect and the user's attention.

For example, in the case of running using a treadmill, the curved road to the left and right can be displayed on the screen of the audiovisual system, but the motion change that can be felt by the user does not occur. It is difficult to expect an increase in exercise effects.

In addition, most of the conventional exercise equipment is limited to exercise items that perform simple movements such as a treadmill or a cycle, in which the implementation of the movement is simple, and there is a limit in inducing interest and interest of consumers.

Recently, various virtual reality devices using virtual reality have been proposed, and these virtual reality devices connect a computer to a motion realization device to physically change the virtual environment by a program through the motion realization device. By making the change appear, the user can perceive and feel the virtual situation as the actual situation.

As a representative device for such a virtual reality experience, a riding type in which a chair, a car, a helicopter, and a horse-shaped vehicle is displaced according to an image shown on a large screen in a sitting position is widely used. Such a driving simulation apparatus installs a plurality of hydraulic or pneumatic cylinders at the lower part of the vehicle and applies a control signal to the cylinders to displace or vibrate the chair or horse-shaped vehicle to the front, rear, left and right. To implement various operations.

However, the riding simulation device using hydraulic or pneumatic cylinder has to convert the position control signal to pneumatic or hydraulic control signal, and the compression conditions of the pressure transmission medium must be satisfied, which results in complicated equipment and high manufacturing cost. As the weight is increased, not only the installation place is restricted, but also there is a problem in that the rapidity of the operation reaction is reduced and the reality is reduced.

Characterized in that it comprises a.

As a preferred feature of the present invention, when the belt pulley A and the belt pulley B is rotated in conjunction with the pulley belt as a power transmission means for transmitting the rotational force of the footrest B to the footrest A, each of the outer diameter of the pulley A and the footrest The angles of rotation of B are at different points.

As a preferable feature of the present invention, the universal joint A and the universal joint B provided with the left and right surfaces of the middle frame for rolling driving are mounted in a straight line in the front and rear directions so that the front and rear surfaces of the middle frame are upward. It is not to yaw in the downward direction.

When described with reference to the drawings showing the operation and function of the curving simulation apparatus according to the present invention configured as described above are as follows.

FIG. 7 is a perspective view of the rotating unit 30 in FIG. 2, which illustrates a driving state of the pivoting operation of the footrest A 32 and the footrest B 33 and the interlocking operation of the wheel part 40, and FIG. 8 shows the foothold A ( 32) and the operation state of the left and right turn of the footrest B (33), Figure 9 is an analysis of the rotational force and the transfer angle by the frictional force and driving force with the wheel 42 on the track belt (22) FIG. 10 shows a rolling drive that operates to incline up and down with the operation state of the footrest A 32 and the footrest B 33 when the wheel 42 is turned to the left at the right end of the track belt 22. 11 shows a rolling drive operated to be inclined up and down and the operating state of the footrest A 32 and the footrest B 33 when the right direction of the wheel 42 is switched at the left end of the track belt 22. 12, the rotation angles of the footrest A 32 and the footrest B 33 due to the difference in the outer diameter of the belt pulley A 31 and the belt pulley B 34 are different from each other. The same state is shown, and FIG. 13 shows a structure in which the left foot and the right foot can be stepped to be compatible with the footrest A 32 and the footrest B 33, and the foothold A 32 and the footrest B (33) so that the rotation is smooth without slipping. Rotational support 32A, 32B, 32C, 33A, 33B protruding from the upper surface of the figure is shown, and FIG. 14 is a flow chart showing an operation process for the curving simulation apparatus according to the present invention.

Next, with reference to the drawings shown in detail with respect to the operation state and function, the wheel 42 is in contact with the upper surface of the track belt 22 that is rotated forward and backward by the drive motor 27 The friction force is generated, and the friction force drives the wheel 42 and rotates the wheel 42 to the left and right while the rotating plate 35 and the footrest B 33 fixed to the wheel 42 simultaneously rotate. In addition, the rotational force is shown in the interlocking operation state that the footrest A 32 is rotated by the belt pulley B 34, the pulley belt 36, and the belt pulley A 31.

The friction force and the driving force will be described in detail later with reference to FIG. 9, and as shown in FIG. 8, the pulley belt 36 rotates clockwise while rotating the belt pulley B 34 in the clockwise direction. It is transmitted to the belt pulley A (31) and the rotational force transmitted to the belt pulley A (31) will rotate the footrest A (32).

In addition, the position where the right foot and the left foot are placed on the footrest A 32 and the footrest B 33 are shown.

Similarly, in the case of the left turn, the driving of the pulley belt 36 rotates in the counterclockwise direction, and the rotational force is transmitted from the belt pulley B 34 to the belt pulley A 31, and the footrest A 32 is rotated. .

In FIG. 9, the force due to the rotation of the track belt 22 applied to the wheel 42 in the Y-axis direction is referred to as 'F', and the wheel 42 moves at an upper surface of the track belt 22. When θ is based on the X axis and the radius of the wheel 42 is 'ℓ', the tangential force applied in the rotational direction of the wheel 42, that is, the driving force 'F ₁ ' is as follows.

F ₁ = F sinθ

Further, the frictional force F ₂ applied to the wheel 42 in the tangential vertical direction is as follows.

F ₂ = F cosθ

Therefore, the rotational force M for rotating the wheel 42 is as follows.

M = F ₁ × ℓ

  = F sinθ × ℓ

Here, if the rotational speed of the track belt 22 is 'V', the frictional force F ₂ is proportional to the rotational speed 'V', so as the rotational speed 'V' of the trackbelt 22 is increased, the frictional force F _{2 is} also increased and the X axis And the moving angle θ becomes smaller gradually. Therefore, the direction of movement of the wheel 22 is rotated while being smooth close to the X axis.

On the other hand, since the driving force F ₁ is increased, the rotational force M is also increased proportionally, so that the wheel 42 eventually increases the speed V of the track belt 22 so that the footrest A 32 and the foothold B 33 have the X axis. It can be seen on the basis of FIG. 9 that the force of forming a gentle angle close to and the rotational speed of the wheel 42 is moved while rotating more rapidly.

The friction force F ₂ described above has a direct effect on rolling in the up and down directions of the left and right surfaces to be described with reference to FIG. 10.

FIG. 10 shows that the wheel 42 rotates counterclockwise in the left direction in order for the footrest B 33 to change direction from the right end to the left side.

When the footrest B 33 which has been rotating to the right rotates in the left direction in which the wheel 42 is counterclockwise, the wheel 42 rotates in the forward direction and thus the footrest B 33 also starts to rotate to the left. .

That is, when the track belt 22 rotates at the speed 'V', the footrest B 33 and the foothold A32 are changed in direction as the direction of the wheel 42 changes.

This fact can be seen that the same results as the verification results for the actual motion.

The same principle applies to the case where the footrest B 33 turns from the left end of the track belt 22 to the right side. The operation state for this is well specified in FIG.

Since the aforementioned frictional force F ₂ acts in the direction perpendicular to the tangential direction of the wheel 42, the rolling drive is started to be inclined in the up and down direction of the footrest B 33.

In general, when the curved course is rotated, if the force of the foot placed on the footrest A 32 is stronger than the foot force pushing the footrest B 33, the left side of the middle frame 12 is downward as shown in FIG. 10. The rolling drive will begin as it descends.

In FIG. 11, when the direction is changed from the left end of the track belt 22 to the right side, the center of the body is moved toward the footrest A 32 and the foothold A32 is pressed to the right of the middle frame 12. As the sub spring 13 is pressed, it can be seen that the right side of the middle frame 12 starts rolling in a downward direction along with the frictional force F ₂ .

In FIG. 12, when the diameter of the belt pulley A 31 is referred to as 'd ₁ ' and the diameter of the belt pulley B 34 is referred to as 'd ₂ ', since the step ₁ is smaller than d ₂ , the footrest A 32 is rotated. When rotating by θ ₁ , the rotation angle θ ₂ of the footrest B 33 is smaller than θ ₁ .

In other words, even if the rotation angle θ ₂ of the footrest B 33 serving as the driving source is small, the rotational angle θ ₁ of the footrest A 32 becomes large, so that the movement effect is doubled.

In FIG. 13, the left foot may be placed on the footrest B 33 as shown by a solid line, and the left foot may be placed on the footrest B 33, and similarly, the foot of the footrest B 33 may be placed on the footrest A 32. It is shown that the other foot, which is provided to be used alternately regardless of which.

In addition, the rotary supports 32A, 32B, 32C, which protrude on the upper surfaces of the footrest A 32 and the footrest B 33 so that the foot can be applied to the footrest A 32 and the footrest B 33 without slipping. 33A and 33B) are also shown.

14 is a flow chart showing the movement and the signal for each operation sequence from the boarding to the product until the movement is described in detail.

First, when you board the product, try to adjust the balance by holding the center of the body.

Check if your body is balanced then if you feel unstable, move your center of gravity and if you can not afford to hold the handle (64) to properly balance the body.

Then, if you start the exercise begins with the track belt 22 rotates at normal speed with a 'beep' sound.

In the beginning, since the footrest A 32 and the footrest B 33 face to the front, friction force between the track belt 22 and the wheel 42 does not arise. Thus, the footrest A 32 and the footrest B 33 are in a stopped state without rotating.

Then, when the user's mind and posture is stabilized and ready for exercise, the footrest B 33 is rotated to the right or left by foot, and then the driving force and the wheel 42 by the friction force between the track belt 22 and the wheel 42 are thereafter. Rotational force is generated.

At this time, the footrest A 32 is also rotated in conjunction with the footrest B 33 and the foothold A32 are rotated at the same time, and thus the balance of the body becomes unstable again.

Again check the body balance and if it is unstable as before, grab the handle (64) along with the weight center movement as before to properly balance the body.

If the movement is continued, the rotation speed of the track belt 22 changes with a beeping sound. The choice of the speed to be shifted is determined randomly, and the speed can be set to various speeds such as low speed, normal speed, and high speed.

Such an exercise is repeated repeatedly until the scheduled exercise time, and when the scheduled time is reached, the exercise ends with a 'beep' sound.

Fig. 15 shows an indoor cycle mounted on the footrest A 32 and a handle 64 and a handle support 67 mounted on the footrest B 33 according to the present invention. It is shown to achieve.

That is, as an embodiment of the device according to the present invention, the conventional indoor cycle is mounted and the left and right rotations and the rolling drive are implemented by holding the handle 64 by hand while serving as a direction changeover with the previous foot. Let's have fun cycling outdoors.

FIG. 16 illustrates in more detail the main functional parts of FIG. 15.

The structure of the existing frame portion 10, the belt track portion 20, the wheel portion 40, and the other portion 50 is the same as before, except that the footrest A (32) and footrest B ( 33 is deformed and the cycle body 61 is mounted on the deformed footrest A 32 and the handle 64 and the handle support 67 are mounted on the footrest B33 as described above. Is shown in detail.

Therefore, in the present invention, the above-described cubing simulation device for an indoor cycle, but may be used in the form of a variety of rides, such as a saddle for riding, a car, a water boat.

The present invention is not limited to the described embodiments, and it is possible to use the application area by changing, and various modifications and variations can be made without departing from the spirit and scope of the present invention. It is self-evident to those who have.
