Utilize the elliptical machine that above-mentioned parts are formed, when operator intend carrying out freely marking time and/
Or during the operator scheme of elliptical trajectory, coordinate refering to Fig. 5 and Fig. 7, utilize both feet right
Described pedal 32 carries out horizontal direction with treadle 31 and exerts a force forward, and carries out Vertical Square
To and exert a force down, the leading section 311 of described treadle 31 can push away the pendulum of described swing arm 21 of pulling
Dynamic portion 212, described swing arm 21 can produce with this transverse axis 121 for center of rotation and swing, and profit
With the setting of this linkage unit 80, described treadle 31, described swing arm 21 can be made to hold with described
The interlink function coordinated is produced 71., then coordinate refering to Fig. 4 and Fig. 6 meanwhile, described in step on
When bar 31 is alternately carried out stampede operation, described treadle 31 is utilized to suppress described game respectively
The guide sliding part 514 of bar 51, can make described joystick 51 with described stopper portion 612 as swing
Center produces swing action, and interlocks this runner 41 rotate through described connecting rod 52, and profit
Drive this flywheel 421 to rotate with this runner 41 with this belt 422, just can produce horizontal vector
Damping with vertical vector.
In addition to above-mentioned operator scheme, when operator intends carrying out the simple operation marked time up and down
During pattern, utilization is double-legged to be carried out vertical direction to described pedal 32 with treadle 31 and executes down
Power, described pedal 32 and treadle 31 can alternately guide sliding parts 514 to described joystick 51
Produce downward stopper effect, and utilize the setting of this damping unit 40, just can produce vertically
The damping of vector.Now, described swing arm 21 produces swing hardly.
When operator intends carrying out sliding steps operator scheme, and utilize both feet to described pedal 32 with step on
When bar 31 carries out horizontal direction and exerts a force forward, the leading section 311 of described treadle 31 can push away
Pulling the swing part 212 of described swing arm 21, described swing arm 21 can be with this transverse axis 121 for rotation
Center produces and swings, and utilizes the setting of this linkage unit 80, can make described treadle 31,
Described swing arm 21 produces, with described handle 71, the interlink function coordinated.
Therefore, operator can select different operator schemes for demand, such as: up and down
Mark time and the front and back operator scheme of elliptical trajectory, sliding steps operator scheme or the most upper and lower
Mark time operator scheme.
For another example the solid line of Fig. 6 is with shown in imaginary line (that is, dotted line), shows portion 613 of should being pulled
When being positioned in Fig. 6 the right-hand end of this driving screw 622, coordinate refering to Fig. 3, this guide unit
One is produced between pivot part 513 and rotating shaft 411 central point of this damping unit 40 of 50
First distance D1, when the guide sliding part 514 of described joystick 51 is in (Fig. 6 vacation of a lower position
Think line) and a high position (Fig. 6 solid line) between conversion time, this lower position and this high position
Guide sliding part 514 (or the rearward end of this treadle, Fig. 6 does not shows, Fig. 5 and Fig. 7 please be join) between
One is had less to trample degree of depth h1.
The most as shown in Figure 8, coordinate different operators or different operational requirements, work as startup
The motor 621 of this adjustment unit 60, and when making this driving screw 622 rotate, utilize this guide screw
The effect that bar 622 is screwed with this swivel nut 614, can adjust the portion of being pulled of this moving part 61
613 produce displacement along this driving screw 622, and make this moving part 61 with this articulated section 611 be
Center of rotation produces swing, and makes this stopper portion 612 drive the pivot of this guide unit 50
Portion 513 produces convergence relative to the rotating shaft 411 of this damping unit 40, and steps on described in adjusting
The rearward end 312 of bar 31 trample the degree of depth.
And the solid line of Figure 11 is with shown in imaginary line, shows that portion 613 of should being pulled is positioned at this driving screw
622 stage casing time, coordinate refering to Fig. 8 and Fig. 9, the pivot part 513 of this guide unit 50
And produce one between rotating shaft 411 central point of this damping unit 40 less than this first distance
The second distance D2 of D1, when the guide sliding part 514 of described joystick 51 is at a lower position (figure
11 imaginary lines) and a high position (Figure 11 solid line) between conversion time, this lower position and this height
The guide sliding part 514 of position (or the rearward end of this treadle, Figure 11 does not shows, refers to Figure 10
And Figure 12) between have one to trample more greatly deeply more than this less trample degree of depth h1 one
Degree h2.And along with this is got over towards the left-hand end position of this driving screw 622 in Figure 11 by portion 613 of pulling
During shifting, trampling the degree of depth can be increasing, if on the contrary, starting this motor 621 and make this be subject to
Pull portion 613, more towards in Figure 11 during the right-hand end displacement of this driving screw 622, tramples the degree of depth and can get over
Come the least, adjust relatively easy.
Therefore, this adjustment unit 60 is utilized just can to adjust the rearward end 312 of described treadle 31
Trample the degree of depth, and utilize this adjustment unit 60 to drive the pivot part 513 of this guide unit 50
Horizontal displacement is produced, it is not necessary to undertake pedal list relative to the rotating shaft 411 of this damping unit 40
Unit 40 or the load of other components, this motor 621 drives load little and can reduce cost, adjusting
Whole operation is the most relatively easy, really can reach the purpose of the present invention.
It is noted that in the above embodiment of the present invention, this adjustment unit 60 utilizes one
Individual moving part 61 and a driving group 62 can simultaneously drive two guide units 50, the most also
This adjustment unit 60 can be arranged two moving parts 61 and two driving groups 62, and utilize institute
State moving part 61 and drive two guide units 50 respectively, also with coordinating of described driving group 62
Intended Adjustment effect (not shown) can be reached.
