Wherein, the pedal group includes: the pedal is arranged at the tail end of the driving rod, the front end of the driving rod is connected with the connecting rod, and the driving rod part of the pedal group, which is close to the middle part, is pivoted on the driving shaft through a shaft sleeve.

Above-mentioned elliptical machine still includes: a handle which is arranged on the body and can be held in a retractable way during movement.

Elliptical machine, through the connected mode of connecting rod and pedal group and base and pedal group and articulate connected mode for articulate rotation drives the motion of pedal group and connecting rod, and crank and connecting rod have injectd pedal group's motion range again simultaneously, make pedal group can simulate ellipse and the orbit of marking time. The elliptical trainer has small volume, convenient use and low manufacturing cost.

Through the arrangement of the connection positions of the pedals and the driving rod, the driving rod and the connecting rod, and the connection positions of the driving rod and the crank, the smoothness of the movement of the pedal group is further increased, and the experience feeling is enhanced.

Can accomodate and the lift that can hold when moving handle that contracts through setting up one on the fuselage for the sporter is in both hands can be held when the elliptical motion on the handle that contracts rises on, accomplish simulation climbing movement track when the health leans forward biped operation pedal group, accomplish the simulation during the backward hard biped operation pedal group of squatting and squat deeply and carry buttockss movement track.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 2, the present embodiment provides an elliptical machine, including: the device comprises a base 1, a machine body 2 arranged on the base 1, a connecting rod 3, a pedal group 4 and a crank (not marked in the figure) arranged in the machine body 1.

As shown in fig. 3, the crank is provided with a driving shaft 5, and the pedal group 4 is pivoted on the driving shaft 5 through a shaft sleeve 7 at a position close to the middle part. One end of the connecting rod 3 is coupled to the front end of the base 1, and the other end of the connecting rod 3 is coupled to the front end of the pedal group 4.

The pedal group 4 includes: the pedal 41 is arranged at the tail end of the driving rod 42, the front end of the driving rod 42 is connected with the connecting rod 3, and the part of the driving rod 42, close to the middle part of the pedal group 4, is pivoted on the driving shaft 5 through a shaft sleeve 7.

The rotation of the crank drives the movement of the pedal group 4 through the driving shaft 5, the movement of the pedal group 4 drives the movement of the rod 3, and meanwhile, the crank and the connecting rod 3 limit the movement amplitude of the pedal group 4, so that the pedal group can simulate elliptical and stepping movement tracks. The elliptical trainer has small volume, convenient use and low manufacturing cost.

Furthermore, through the arrangement of the connection positions of the pedal 41 and the driving rod 42, the driving rod 42 and the connecting rod 3, and the driving rod 42 and the crank, the smoothness of the movement of the pedal group is increased, and the experience feeling is enhanced.

As shown in fig. 4, the elliptical machine according to this embodiment may further include a retractable handle 30 on the machine body. When the elliptical machine is not used, the lifting and contracting handle 30 can be stored, so that the elliptical machine occupies a small space. Or, when the ellipse and the stepping motion track are simulated, the lifting and contracting handle 30 is also stored, and the experience is enhanced. When climbing motion needs to be simulated, the lifting and contracting handle 30 is lifted, a sporter holds the lifting and contracting handle 30 by two hands, and the body leans forward and operates the pedal group by two feet to finish the simulation of climbing motion trail. When the simulation deep-squat hip-lifting movement is needed, the sporter holds the lifting handle 30 by both hands, and the body squats backwards to exert force and operates the pedal group by both feet so as to finish the simulation deep-squat hip-lifting movement track.

In summary, in the elliptical machine according to the present embodiment, the rotation of the crank drives the movement of the pedal set and the connecting rod through the connection manner of the connecting rod and the pedal set and the base, and the crank and the connecting rod limit the movement range of the pedal set, so that the pedal set can simulate elliptical and stepping movement tracks. The elliptical trainer has small volume, convenient use and low manufacturing cost.

Through the arrangement of the connection positions of the pedals and the driving rod, the driving rod and the connecting rod, and the connection positions of the driving rod and the crank, the smoothness of the movement of the pedal group is further increased, and the experience feeling is enhanced.

Can accomodate and the lift that can hold when moving handle that contracts through setting up one on the fuselage for the sporter is in both hands can be held when the elliptical motion on the handle that contracts rises on, accomplish simulation climbing movement track when the health leans forward biped operation pedal group, accomplish the simulation during the backward hard biped operation pedal group of squatting and squat deeply and carry buttockss movement track.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
