Abstract

The utility model provides an elliptical machine, including the cantilever, pedal group, crank, connecting rod and the gyro wheel be connected with the cantilever, be equipped with a drive shaft on the crank, the one end of gyro wheel and connecting rod is all established and is established in the drive shaft, and the other end and the cantilever of connecting rod are connected, and pedal group connects on the gyro wheel. Elliptical machine through the mode that increases gyro wheel and connecting rod for crank rotation drives the connecting rod motion, and connecting rod motion drives footboard group and slides around on the gyro wheel, and then increases footboard group seesaw range, consequently, can reduce articulate yardstick under the certain circumstances of footboard group seesaw range, reduces the circumference size of crank disc, reduces elliptical machine occupation of land space, makes elliptical machine be applicable to the little space and uses. And due to the use of the rollers, the pedal group moves more smoothly, and the experience feeling is enhanced.

Description

Elliptical trainer

Technical Field

The utility model relates to a sport equipment technical field especially relates to an elliptical machine.

Background

As shown in fig. 1, in a conventional elliptical machine, the positions of a pedal pipe 11 and a crank (not shown) are fixed, and the pedal pipe 11 is connected to a driving shaft 12 provided on the crank. The step size of the elliptical trainer is determined by the circumferential dimension of the crank disc 13. To meet the step size, the disc circumference of the crank disc 13 must be increased.

The large-stride elliptical trainer occupies a large area, and the realization of large stride can realize the motion trail of the large-stride elliptical trainer only by making the sizes of the crank disk and the whole aircraft body very large. Is not suitable for small space.

SUMMERY OF THE UTILITY MODEL

Therefore, the utility model discloses the technical problem that solve is: the elliptical machine is suitable for being used in a small space, and is smoother in movement and stronger in experience.

Therefore, the utility model provides an elliptical machine, including the cantilever, with the pedal group, crank, connecting rod and the gyro wheel that the cantilever is connected, be equipped with a drive shaft on the crank, the one end of gyro wheel and connecting rod is all established and is established in the drive shaft, the other end and the cantilever connection of connecting rod, pedal group connects on the gyro wheel.

Wherein, set up flutedly on the gyro wheel, the one end of footboard group sets up on the recess, and the other end of footboard group is connected with the cantilever.

Elliptical machine through the mode that increases gyro wheel and connecting rod for crank rotation drives the connecting rod motion, and connecting rod motion drives footboard group and slides around on the gyro wheel, and then increases footboard group seesaw range, consequently, can reduce articulate yardstick under the certain circumstances of footboard group seesaw range, reduces the circumference size of crank disc, reduces elliptical machine occupation of land space, makes elliptical machine be applicable to the little space and uses. And due to the use of the rollers, the pedal group moves more smoothly, and the experience feeling is enhanced.

Detailed Description

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

As shown in fig. 2 to 4, the present embodiment provides an elliptical machine, including: cantilever 21, pedal group 22, the crank (not marked in the figure), connecting rod 23 and gyro wheel 24 that are connected with cantilever 21, be equipped with a drive shaft 25 on the crank, the one end of gyro wheel 24 and connecting rod 23 all overlaps and is established on drive shaft 25, and the other end of connecting rod 23 is connected with cantilever 21, and pedal group 22 connects on gyro wheel 24.

As shown in fig. 5, in order to prevent the pedal group 22 from shifting and sliding off the roller 24, a groove 26 may be formed on the roller 24, one end of the pedal group 22 is disposed on the groove 26, and the other end of the pedal group 22 is connected to the cantilever 21.

The rotation of the crank can drive the connecting rod 23 to move through the driving shaft 25, and the movement of the connecting rod 23 drives the pedal group 22 to slide back and forth on the roller 24.

when the crank is rotated to the front position, the left connecting rod 23 is linked with the cantilever 21, the cantilever 21 is linked with the pedal group 22, so that the left pedal group 22 slides to the foremost position on the roller 24, and at the same time, the right pedal group 22 slides to the rearmost position on the roller 24. Enabling forward and backward movement of the set of pedals 22.

In summary, in the elliptical machine according to the present embodiment, the connecting rod is driven by the crank to rotate by increasing the roller and the connecting rod, the pedal group is driven by the connecting rod to slide back and forth on the roller by the connecting rod, and the back and forth movement amplitude of the pedal group is further increased, so that the size of the crank can be reduced, the circumferential size of the crank disk can be reduced, the floor space of the elliptical machine can be reduced, and the elliptical machine is suitable for small space use under the condition that the back and forth movement amplitude of the pedal group is constant. And due to the use of the rollers, the pedal group moves more smoothly, and the experience feeling is enhanced.

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.
