ELLIPTICAL EXERCISER
Abstract
An elliptical trainer comprises a frame set, two first
transmission rods, two second transmission rods, two footboard
assemblies, a holding flywheel assembly, a stand flywheel assembly,
and two eccentric link rods. When a user is stepping the two
footboard assemblies and taking exercise with elbows on the two
second transmission rods, the two footboard assemblies may be
stepped up and down to recycle and each second transmission rod may
be rotated to reciprocate along an arc and centered in a stand ear.
At this time, each drag rod of two stand ears arranged right and
left may pull the corresponding eccentric link assembly to rotate
360 degree and the torque of the third flywheel may not overlap
each drag rod of each eccentric link assembly vertically.
Accordingly, the arrangement of each eccentric link assembly may
prevent the swing operation from being stuck to pause or operate
unsmoothly.

Description
FIELD OF THE INVENTION
[0001] The present invention relates to an elliptical trainer, and
more particularly to an elliptical trainer capable for being
stepped elliptically.
BACKGROUND OF THE INVENTION
[0002] The conventional elliptical trainer is used for consuming
the movement of stepping by stepping the footboards to drive the
flywheel(s), such as inertia wheel. The flywheel may be user to
drive the drag rod through a flexible member, such as belt.
However, when the drag rod is pulling the flywheel to rotate, the
torque of the flywheel may be overlapped the drag rod so that the
total torque is zero to result in that the flywheel is unable to be
driven or rotates unsmoothly.
[0003] In order to solve above drawback, China patent no.
201010563057.7 has disclosed that a magnetic actuator is used to
prevent the flywheel from stopping rotating. However, if another
magnetic member is used, the cost may be higher and increased and
alignment is necessary while assembling to prevent from vibrating
and swinging.
[0004] In addition, the footboards and the handlebars of the
conventional elliptical trainer are linked so that they may not
step up and down or operate with the handlebars separately and
individually. Therefore, the conventional elliptical trainer may
only provide to swing forward and backward and step elliptically.
It may not provide to step up and down individually. Besides, the
damping of the conventional elliptical trainer is performed by the
magnetic-control wheel. It is unable to train the hands or feet
individually. The amplitude and range of the damping is controlled
electronically or by hand. It is inconvenient to use.
[0005] Accordingly, the present invention may be stepped up and
down and swung forward and backward. The ranges of moving up and
down and forward and back may be adjusted while the user is
training based on the amount of exercise. The damping is not
necessary to be controlled electronically or by hand. Obviously,
the functions and operations of the present invention are
improved.
[0006] In view of the foregoing circumstances, the inventor has
invested a lot of time to study the relevant knowledge, compare the
pros and cons, research and develop related products. After quite
many experiments and tests, the "elliptical trainer" of this
invention is eventually launched to improve the foregoing
shortcomings, to meet the public use.
SUMMARY OF THE INVENTION

flywheel 61 of the stand flywheel assembly 6 is pivoted with one
end of the second link rod 72. One end of the second link rod 72
opposite to the first link rod 71 is pivoted with the bottom end of
the corresponding drag rod 73.
[0040] Accordingly, the tail end of the swinging rod 23 of each
first transmission rod 2 is pivoted to the front ear 42 of the
corresponding footboard assembly 4 and the tail end of the stand
rod 33 of each second transmission rod 3 is pivoted to the rear ear
43 of the corresponding footboard assembly 4. When the two swinging
rods 23 is swung and the two footboard assemblies 4 is stepped up
and down, the two first transmission rods 2 may drive the stand
flywheel assembly 6 and the two second transmission rods 3 may
drive the holding flywheel assembly 5 so that the energies
generated from exercising may be consumed by the stand flywheel
assembly 6 and the holding flywheel assembly 5. Furthermore, the
two first transmission rods 2 and the two second transmission rods
3 may be operated to take exercise with one elbow or two feet
separately or operated together to take exercise with elbows and
two feet. Each second transmission rod 3 is pivoted to the
corresponding stand ear 32 and the stand ear 32 is connected with
corresponding first transmission rod 2 and second transmission rod
3. Therefore, when each first transmission rod 2 and each second
transmission rod 3 are rotated, the stand ear 32 may drive the
corresponding holding rod 31 to swing up and down centered in each
first transmission rod 2 and each second transmission rod 3.
[0041] Please refer to FIG. 5, when a user is stepping the two
footboard assemblies 4 and taking exercise with elbows on the two
second transmission rods 3, the two footboard assemblies 4 may be
stepped up and down to recycle and each second transmission rod 3
may be rotated to reciprocate along an arc and centered in the
stand ear 32. At this time, the drag rods 73 of the two stand ears
arranged right and left may pull the corresponding eccentric link
assembly 7 to rotate an angle of 360 degree and the torque of the
third flywheel 61 may not overlap each drag rod 73 of each
eccentric link assembly 7 vertically. Accordingly, the arrangement
of each eccentric link assembly 7 may prevent the swing operation
from being stuck to pause or operate unsmoothly.
[0042] Please refer to FIG. 6, a second embodiment of the present
invention is illustrated. The difference between the second
embodiment and the first embodiment is described as follows. A
holding rod 31 is connected to the top end of each second
transmission rod 3. The stand ear 32 is arranged at one side of
each second transmission rod 3. The drag ear 34 is arranged at the
side of each second transmission rod 3 opposite to the stand ear
32. The drag ear 34 is provided the drag rod 73 to pivot with.
[0043] Please refer to FIG. 7, a third embodiment of the present
invention is illustrated. The difference between the third
embodiment and the first embodiment is described as follows. The
holding rod 31 id arranged at the top end of each first
transmission rod 2.
