Definitions
- the present invention relates to a stepper exercise machine, and more particularly to a stepper exercise machine capable of stretching the muscles of the let of the user when the front portion of the foot of the user is forced to tilt.
- the elliptical machine provides the same function as the stationary bicycle, for example, the motion of ascending and bending knee.
- the angles of the foot and the leg of the user are substantially the same.
- the front of the foot cannot be tilted to stretch the muscles of the leg, not like the function of the stepper.
- the user must stand with both hands to hold the handles for keeping a balance.
- the structure is complex and bulky, and the price is high. It is usually used in a professional gym, not suitable for domestic use.
- the stationary bicycle the user can sit on the stationary bicycle for doing exercise. But, it also has the shortcomings of a complex and bulky structure and a slightly high price. It cannot be widely used like a stepper which is small in size and low in price.
- a stepper exercise machine as disclosed in U.S. Pat. No. 6,705,975 comprises a base, two platform elements, and two elastic elements.
- the two platform elements are pivotally coupled to the base.
- the two elastic elements are located between the base and the corresponding platform elements.
- the two elastic elements provide the recoil force for the platform elements, instead of mechanical hydraulic pressure, so that the structure of the stepper exercise machine is simplified and the user can choose a different way for operation.
- one end of the platform unit is pivotally connected to the base, and the other end of the platform unit is connected to the elastic element.
- one end of the platform unit, connected to the base functions as a pivot
- the other end of the platform unit, connected to the elastic member is pedaled up and down.
- the user is allowed to move in the up and down direction when the machine is operated.
- the operation will be stopped immediately. This way is unable to reduce the force exerted by the user or bring the user's feet to reciprocate in an inertia manner. It is very inconvenient.
- the exercise effect of a conventional stepper exercise machine on the market is to reciprocate the legs, knees and ankles with a small angle.
- the foot can be tilted to provide a partial stretching effect
- the machine is operated by means of the user's weight. This is obviously against the user's natural walking posture and cannot provide a natural and comfortable operation for the user. Therefore, it cannot be used for stretching.
- the primary object of the present invention is to provide a stepper exercise machine.
- a pair of flywheels made of a metal material is simultaneously driven to provide an acceleration effect.
- the rotation of a drive gear is to speed up, so that the user can reduce the force exerted to two pedals and a drive wheel unit continues to turn in the same direction.
- the two pedals can be pedaled continuously and smoothly.
- the front portion of the foot is forced to tilt to stretch the muscles of the leg of the user, which is the main feature of the present invention.
- the present invention is to provide a stepper exercise machine. Through a transmission mechanism that the two pedals drive the drive gear to link a transmission wheel and the two flywheels, the user can do exercise in a sitting manner or in a standing manner.
- the stepper exercise machine has the advantages of occupying less space, a low cost, and a low failure rate. This is a further feature of the present invention.
- the present invention is to provide a stepper exercise machine.
- the user may have a choice for a desired stepping position.
- the tilt angle of the foot is relatively large during exercise, that is, the relative effect of stretching is strong; when the heel is positioned forward, the tilt angle of the foot is relatively small during exercise, that is, the relative effect of stretching is weak.
- the user himself/herself can adjust the angle of stretching to achieve a more extensive applicability.

Abstract
A stepper exercise machine is provided. When a pedal is pedaled by a user, a drive gear is rotated forward or rearward. One end of a link is rotated about a drive rod, and a turning lever connected to the other end of the link is confined by a second accommodation trough of the pedal, so that the link brings the pedal to move in the up-down direction and the front-rear direction. In cooperation with a shaft which is fixed, a sleeve is rotatable relative to the shaft. When the pedal is driven, a first accommodation space provides a space for the pedal to move in the front-rear direction. By means of the action of two flywheels to provide an acceleration effect, the rotation of the drive gear is to speed up, so that the user can reduce the force exerted to the pedal.

- The present invention relates to a stepper exercise machine, and more particularly to a stepper exercise machine capable of stretching the muscles of the let of the user when the front portion of the foot of the user is forced to tilt.
- There are many indoor leg training machines on the market, such as a treadmill, a stepper, an elliptical machine (commonly known as an elliptical machine, a space walking machines, etc.), and a stationary bicycle. It is easy to hurt the knee and ankle of the user because of vibration and pressure.
- The elliptical machine provides the same function as the stationary bicycle, for example, the motion of ascending and bending knee. The angles of the foot and the leg of the user are substantially the same. The front of the foot cannot be tilted to stretch the muscles of the leg, not like the function of the stepper.
- As to the aforementioned elliptical machine, the user must stand with both hands to hold the handles for keeping a balance. The structure is complex and bulky, and the price is high. It is usually used in a professional gym, not suitable for domestic use. As to the stationary bicycle, the user can sit on the stationary bicycle for doing exercise. But, it also has the shortcomings of a complex and bulky structure and a slightly high price. It cannot be widely used like a stepper which is small in size and low in price.
- A stepper exercise machine as disclosed in U.S. Pat. No. 6,705,975 comprises a base, two platform elements, and two elastic elements.
- The two platform elements are pivotally coupled to the base. The two elastic elements are located between the base and the corresponding platform elements. The two elastic elements provide the recoil force for the platform elements, instead of mechanical hydraulic pressure, so that the structure of the stepper exercise machine is simplified and the user can choose a different way for operation.
- However, one end of the platform unit is pivotally connected to the base, and the other end of the platform unit is connected to the elastic element. When the user pedals the machine, one end of the platform unit, connected to the base, functions as a pivot, and the other end of the platform unit, connected to the elastic member, is pedaled up and down. The user is allowed to move in the up and down direction when the machine is operated. When the user doesn't apply force, the operation will be stopped immediately. This way is unable to reduce the force exerted by the user or bring the user's feet to reciprocate in an inertia manner. It is very inconvenient.
- Particularly, the exercise effect of a conventional stepper exercise machine on the market is to reciprocate the legs, knees and ankles with a small angle. Although the foot can be tilted to provide a partial stretching effect, the machine is operated by means of the user's weight. This is obviously against the user's natural walking posture and cannot provide a natural and comfortable operation for the user. Therefore, it cannot be used for stretching.
- The primary object of the present invention is to provide a stepper exercise machine. When the user pedals the machine, a pair of flywheels made of a metal material is simultaneously driven to provide an acceleration effect. The rotation of a drive gear is to speed up, so that the user can reduce the force exerted to two pedals and a drive wheel unit continues to turn in the same direction. The two pedals can be pedaled continuously and smoothly. The front portion of the foot is forced to tilt to stretch the muscles of the leg of the user, which is the main feature of the present invention.
- The present invention is to provide a stepper exercise machine. Through a transmission mechanism that the two pedals drive the drive gear to link a transmission wheel and the two flywheels, the user can do exercise in a sitting manner or in a standing manner. The stepper exercise machine has the advantages of occupying less space, a low cost, and a low failure rate. This is a further feature of the present invention.
- The present invention is to provide a stepper exercise machine. Through the arrangement of the two elongated pedals, the user may have a choice for a desired stepping position. When the heel is positioned rearward, the tilt angle of the foot is relatively large during exercise, that is, the relative effect of stretching is strong; when the heel is positioned forward, the tilt angle of the foot is relatively small during exercise, that is, the relative effect of stretching is weak. The user himself/herself can adjust the angle of stretching to achieve a more extensive applicability.

One end of thelink 34 is rotated about thedrive rod 32. The turninglever 35 connected to the other end of thelink 34 is limited by thesecond accommodation trough 53 of thepedal 5, so that the rotation of thelink 34 brings thepedal 5 to move in the up-down direction and the front-rear direction. Theshaft 22 is fixed, and only thesleeve 23 is rotatable relative to theshaft 22. When thepedal 5 is driven by thelink 34 to move in the front-rear direction, thefirst accommodation space 52 provides a space for thepedal 5 to move in the front-rear direction. - When the
link 34 drives thedrive rod 32 and thedrive gear 33 to rotate, thedrive gear 33 drives the transmission gear 43 and the twoflywheels 44 to rotate because thedrive gear 33 meshes with the transmission gear 43. After that, by means of the inertia rotation of the twoflywheels 44, the transmission gear 43 is driven to rotate thedrive gear 33 so that theuser 200 can reduce the force exerted to thepedal 5. - In addition, the heights of the
shaft 22, thedrive rod 32, and thespindle 42 are substantially the same. When theheel 210 of theuser 200 is turned to the lowest point of thelink 34 along with the rear end of thepedal 5, the front portion of the foot is forced to tilt to stretch the muscles of theleg 220 of theuser 200. - Referring to
FIGS. 6 to 8 as well asFIGS. 9 to 10 , when theuser 200 sits with his/herheel 210 to exert force to the rear end of thepedal 5, thedrive gear 33 is rotated forward. One end of thelink 34 is rotated about thedrive rod 32. The turninglever 35 connected to the other end of thelink 34 is limited by thesecond accommodation trough 53 of thepedal 5, so that the rotation of thelink 34 brings thepedal 5 to move in the up-down direction and the front-rear direction. Theshaft 22 is fixed, and only thesleeve 23 is rotatable relative to theshaft 22. When thepedal 5 is driven by thelink 34 to move in the front-rear direction, thefirst accommodation space 52 provides a space for thepedal 5 to move in the front-rear direction. - When the
link 34 drives thedrive rod 32 and thedrive gear 33 to rotate, thedrive gear 33 drives the transmission gear 43 and the twoflywheels 44 to rotate because thedrive gear 33 meshes with the transmission gear 43. By means of the action of the inertia rotation of the two metal andextra-heavy flywheels 44 to provide an acceleration effect, the rotation of thedrive gear 33 is to speed up, so that theuser 200 can reduce the force exerted to the pedal and thedrive wheel unit 3 continues to turn in the same direction. The twopedals 5 can be pedaled continuously and smoothly. - In addition, the heights of the
shaft 22, thedrive rod 32, and thespindle 42 are substantially the same. When theheel 210 of theuser 200 is turned to the lowest point of thelink 34 along with the rear end of thepedal 5, the front portion of the foot is forced to tilt to stretch the muscles of theleg 220 of theuser 200. -
