Abstract

The present invention relates to a fitness and entertainment device that utilizes the precession effect of a flywheel gyro to generate autonomous deflection, which comprises a rotatable base that can stably support all components, a stand fixed to the rear side of the base, and a suspended frame pivotally connected to the top of the stand; wherein the suspended frame is provided with pivoting columns, a seat cushion, a grip handle, a pedal crank, and a pedal wheel. The invention relates to a crankshaft having a plurality of components, a handle, a blocked arc wing and a flywheel driven by a chain transmission system; the stand is provided with a blocking portion composed of a plurality of pulleys at a position opposite to the blocked arc wing; and a ground-contacting support shaft is provided at the rotation center of the rotatable base; when the user continuously steps on the crankshaft to rotate the flywheel, the user obtains appropriate physical motion inertia and stable angular momentum. After that, you can apply torque deflection to the "angular momentum direction" of the flywheel's rotation axis by applying pressure to the handlebars or shifting the user's own center of gravity at any time. At this time, the frame will immediately perform "gyro precession" in the expected pressure direction, and at the same time, together with the base, it will immediately start to rotate in the expected direction with the support shaft as the rotation center. That is, it will immediately reflect and produce the "gyro precession effect" when the "angular momentum direction" of the flywheel axis is affected by external torque. When you want to stop or rotate in another direction, you only need to move your body's center of gravity or apply force to the handlebars to make the frame tilt back or tilt to the other side, and you can get the expected deflection motion effect.

Description

Fitness and entertainment device that uses the precession effect of a flywheel gyro to produce autonomous deflection

This invention is related to a fitness and entertainment device that uses the gyro precession effect of a flywheel to produce autonomous deflection. More specifically, it refers to a device that does not require any external force or external power assistance, but only needs to be driven continuously by the user himself, so that the overall device can perform the "gyro precession effect" in the expected direction at any time according to the user's simple pressure or center of gravity shift. In particular, the device can be repeatedly operated and can sensitively follow the shift of the center of gravity and deflect in real time, so that the user feels like riding in the air, flying and floating, and it is a novel invention that is highly safe to use and industrially progressive.

According to the so-called "angular momentum direction", it refers to an invisible natural angular momentum force generated along one side of the central axis of rotation of an object when the object rotates. This force is at right angles to the direction of the object's movement. This angular momentum force can keep the object in the so-called dynamic rotation balance. For example, the stable upright rotation state of a gyroscope is a common manifestation of this physical effect. The magnitude of this angular momentum force is positively correlated with the rotation rate of the object. In order to be able to concretize this invisible angular momentum force and to facilitate the explanation of the technology and usage characteristics of the present invention, the term "angular momentum direction" is used in the specification to represent it.

As mentioned above, the so-called "gyroscopic precession effect" refers specifically to the situation that when the rotating object is in a dynamic rotational equilibrium state, if an external force interferes with the "angular momentum direction", the object will begin to perform physical precession action toward the disturbed side, which is called the gyroscopic precession effect.

Of course, the above-mentioned physical phenomena are basic physical knowledge and are not the patent claim features that the present invention intends to cover, so they will not be elaborated on in detail.

Therefore, among the many sports equipment or entertainment devices currently available on the market, the products commonly known as "Segway" and the present invention both use gyroscopes and are worth mentioning. However, as is well known, they are not only expensive, but also use many gyroscopes only for the purpose of detecting and obtaining the dynamic balance of the vehicle body, that is, the gyroscope is used as a posture detection instrument to sense the deviation direction of the user's body posture (center of gravity), and then used as a basis for operating the electric motors in the wheels on both sides to operate accordingly. In short, it only allows the gyroscope to show its due gyroscopic effect and detection function, but does not utilize the aforementioned "angular momentum direction" and "gyroscopic precession effect" and other functions.

Furthermore, the gyroscope and electric motor used in the Segway balance car must rely on external power supply to achieve its operating efficiency. Once the power supply is lost, it will be equivalent to waste. In particular, when it is used as a walking tool, there are no safety facilities, and countless casualties have occurred. Therefore, it can only be discontinued in the end.

Secondly, we can also see the emergence of several patents commonly known as "REALRYDER" exercise bikes, such as US Patent No. 11235199 and US Patent No. 10398934. From the design of the patent, we can see that the main purpose is to allow the frame and flywheel to change the center of gravity of the body to make left and right tilt movements simultaneously, thereby simulating the turning action similar to riding a bicycle. However, when the usage characteristics are further studied, it can be found that it only allows the user to feel the body tilt, but the overall structure does not achieve the so-called real turning state. In other words, this product only provides a "pretend" state that looks like turning, but in fact it is just a creative gimmick.

Of course, although the flywheel in this patent application can also generate angular momentum when it rotates and may have a natural balance return effect, it can only be used to balance the frame and has no other additional functions.

Therefore, based on the above facts, the inventor, with his many years of practical experience in this industry and a deep understanding of the innovative fitness and entertainment product model that can be achieved by using the "gyro precession effect", actively invested in research and development, and the present invention was able to be launched early; therefore, its main purpose is to provide a device that does not require any external force or external electricity, but only needs to be driven by the user himself, so that the overall device can be adjusted at any time according to the user's simple pressure or center of gravity shift. The device can perform the "gyroscopic precession effect" in the expected direction. In particular, the device can be operated repeatedly and can sensitively follow the shift of the center of gravity and deflect in real time, thereby truly presenting the same actual turning action as riding a bicycle, and even making the user feel like riding in the air, flying and floating, with excellent fitness and entertainment effects. At the same time, it is highly safe to use, economical and industrially progressive, which is the main purpose of the invention.

Another purpose of the present invention is to make full use of the automatic stabilization effect of angular momentum, and add the immediate turning performance that can be exhibited when the "angular momentum direction" is subjected to deflection torque, so as to form a gorgeous dance-like movement mode in conjunction with the fast rhythm and the skilled operation skills of the user's core muscles, thereby infinitely increasing the fun of its use.

Yes, it mainly includes a rotatable base that can stably support all components, a stand fixed to the rear side of the base, and a suspended frame pivoted to the top of the stand; wherein the suspended frame is respectively provided with a pivot column, a seat cushion, a grip handle, a pedal crank, a blocked arc wing and a flywheel driven by a chain transmission system; the stand is provided with a blocking portion composed of several pulleys at the position of the blocked arc wing; and a ground-attached support shaft is provided at the rotation center point of the rotatable base; yes, through the composition of the above components, when the user continues to pedal the crank to rotate the flywheel until a suitable After the physical motion inertia and angular momentum are stabilized, you can apply pressure to the handlebars or shift the user's center of gravity at any time to apply torque deflection to the "angular momentum direction" located at the flywheel's rotation axis. At this time, the frame will immediately perform the "gyroscopic precession effect" in the expected pressure direction, and at the same time, together with the base, it will immediately start rotating in the expected direction with the support shaft as the rotation center. When you want to stop or rotate in another direction, you only need to move your body's center of gravity or apply force to the handlebars to make the frame tilt back or tilt to the other side, and you can get the expected deflection motion effect.

In order to further understand the technical means and features of the present invention, it is described in detail below with some diagrams:

First, please refer to the first, second, third and fourth figures, which are diagrams of a preferred embodiment of the present invention. It can be seen from the figure that it includes:

A rotatable base 10 that can stably support all components, with rotation-assisting pulleys 11 at each end edge and a ground-attached support shaft 12 at the center of rotation;

A stand 20 fixed to the rear side of the base, with a "+-shaped" axle tube 22 and a hollow sleeve 23 at the top arc-shaped interface 21, and interlocked with the corresponding hinge column 31 of the frame 30, and a blocking part 25 composed of several pulleys 24 is provided at the lower part corresponding to the arc wing 35 of the frame 30;

A suspended frame 30 pivoted at the arc-shaped interface 21 at the top of the stand 20, which is provided with a pivot column 31, a seat cushion 32, two grip handles 33, a pedal crank 34, a shielding arc wing 35 and a flywheel 36 driven by a chain transmission system 40;

As shown in the sixth, seventh, eighth, ninth and tenth figures, by means of the above-mentioned components, when the user continuously steps on the pedal crank 34 to rotate the flywheel 36 and obtains appropriate physical motion inertia and stable angular momentum, the user can apply pressure to the grip handle 33 or shift the center of gravity of the user at any time to apply torque deflection to the "angular momentum direction" of the rotation axis of the flywheel 36. At this time, The frame 30 will immediately perform the "gyroscopic precession effect" in the expected direction of pressure, and together with the base 10, it will immediately start to rotate in the expected direction with the support shaft 12 as the rotation center. When you want to stop or rotate in another direction, you only need to move your body center of gravity or apply force to the handle 33 to make the frame 30 tilt back or tilt to the other side, so that you can obtain the expected eccentric motion effect.

The aforementioned chain transmission system 40 actually includes a number of related components such as a pedal crank 34, a large gear plate 41, a transmission chain 42, a small passive gear plate 43, etc., which drive the flywheel 36 to rotate rapidly in the expected driving direction. At the same time, in order to prevent the chain transmission system 40 from causing danger during operation, a safety cover 50 is usually provided to cover it. However, since these are the basic configurations of such items, the inventor will not elaborate on them. Please understand.

After that, please refer to the second, fourth and fifth figures. There is another stopper element 311 next to the pivot column 31 of the frame 30, which is used to match the corresponding stopper groove 222 provided at the corresponding part of the axle tube 22, so as to limit the deflection angle of the frame 30 after being stressed, so as to prevent excessive tilting and endangering the safety of use.

Furthermore, since the frame 30 is only supported by the blocked arc wing 35 at the corresponding blocking portion 25 of the vertical frame 20, it can slide freely left and right with the assistance of the pulley 24, making the frame 30 in a deflectable state, and can also naturally offset the load shear stress at the pivot column 31 of the frame 30; in particular, the blocked arc wing 35 can be used as an assembly counterweight, that is, by adding a counterweight block (not shown in the figure) on the appropriate side, the frame 30 can maintain a static hanging state with left and right balance after assembly.

In fact, when the flywheel 36 starts to rotate in place, its physical angular momentum is generated. When a certain speed is reached, the frame 30 will be stabilized and straightened due to the corresponding angular momentum. The angular momentum value required to stabilize the frame 30 is positively correlated with the weight of the user. Afterwards, when the user continues to rotate the flywheel 36 quickly, all the movements of deflecting the center of gravity to the left and right are equivalent to applying a torque deflection to the "angular momentum direction". , so the whole device will immediately perform the "gyroscopic precession effect" in the deflected direction. At the same time, the existing angular momentum will resist the deflection force at any time and push the frame 30 to the correcting direction. In this way, the user can use the core muscle group to resist the angular momentum at any time. In particular, when the flywheel 36 rotates faster, the relative resistance force will be greater, thereby obtaining an excellent exercise effect and control fun.

In practice, the height position of the center point A of the rotation axis of the flywheel 36 should be as close to or aligned with the extension axis B of the pivot column 31 of the frame 30 as possible (see the second figure), so that the expected gyroscopic precession effect can be displayed and fully exerted to the greatest extent. In other words, this is also an important reason why the known "REALRYDER" exercise bike cannot obtain the same gyroscopic precession effect function as the present invention.

Of course, in order to allow the user to quickly slow down or stop the operation of the flywheel 36 in any necessary situation, the preferred embodiment is provided with a brake mechanism 60 between the two grip handles 33 of the frame 30 (i.e., adjacent to the upper part of the flywheel 36) to take into account its safety in use. However, this brake mechanism 60 and its related components are necessary and common configurations of such sports equipment with flywheels, and are not the patent features claimed by the present invention, so they will not be described in detail. In addition, in order to avoid confusion caused by too many figure numbers, some figures are marked with corresponding figure numbers only for specific key points, so as to match the specific exclusive content of each section of the manual, so that it is easy to clearly understand what is pointed to, and please understand.

The main function of the auxiliary rotation pulley 11 provided at each end edge of the base 10 in the above-mentioned embodiment is to reduce the friction between the base 10 and the ground, so as to facilitate the in-situ rotation movement of the overall device; and in order to overcome any potential unevenness of the ground itself, please refer to Figures 11 and 12, which are another preferred embodiment of the present invention. It can be seen from the figure that the overall device can be assembled on a rigid support body 70. In this way, the rigid support body 70 is in contact with the ground, and the overall device can also perform the expected movement on the rigid support body 70 with the support shaft 12 as the rotation axis, and it is no longer necessary to install the auxiliary rotation pulley 11.

As shown in Figures 13 and 14, in terms of design, the present invention can also set the blocked arc wing 35 of the frame 30 on one side close to the flywheel 36, and at the same time, the blocking portion 25 with the pulley 24 is fixed at the corresponding position of the base 10. In this way, the frame 30 can also obtain the effective function of being supported and able to slide left and right.

In summary, this invention has not been seen in similar products on the market or in related publications and documents before the application was filed. It is also a highly technical and creative work that utilizes the laws of physics and nature. It has met the patent requirements for inventions and should be protected by relevant patent laws. Therefore, the application is filed in accordance with the law.
