Two bent type coupled frames 60; Be divided into the relative outside of this two fork 30 and two treadles 40; Respectively should song type coupled frame 60 be set as crooked shaft-like and define be formed with one upright to a section 61 and a traversing section 62; Should be upright to section 61 top tools one first connecting portion 63 is connected in the up-down of elevating adjusting device 50 with the pivot group in rod member 52 lower ends; These traversing section 62 rear ends then tool one second connecting portion 64 are connected in the crank portion 24 of crank-type driver 20 with the pivot group, constitute when crank portion 24 is pressed down by treadle 40 to drive and revolve when moving, and are able to produce through this song type coupled frame 60 drawing forks 30 swing.

Further; Like Fig. 4, shown in Figure 5; The outer tube part 51 of this elevating adjusting device 50 and go up and down between the rod member 52 and can organize and be provided with a C type lining 55, this C type lining 55 1 side tools one flange 551 snaps in the location so that outer tube part 51 1 sides are provided with a perforation 513 for this flange correspondence; These C type lining 55 opposite sides have a profile groove 552, protrude out embedding cunning in this profile groove 552 in projection 521 with cooperation so that interior rod member 52 1 sides of this up-down are provided with an identification; And be provided with perspective window 515 (can be ambient) in these outer tube part 51 1 sides, for this identification is shown in outer tube part 51 outsides with the position of projection 521, reach the effect that makes things convenient for user's identification elevating adjusting device 50 to adjust states with this.

Like Fig. 4, shown in Figure 5; The thrust end 541 of the release navigation button 54 of this elevating adjusting device 50 and control and to be provided with a spiro rod section 543 between the button portion 542; Run through screw 514 and screw togather for this spiro rod section 543 and wear group so that these outer tube part 51 1 sides are provided with one; Can advance to control this thrust end 541 advance and retreat actions through this is controlled button portion 542 and orders about

spiro rod section

543 and 514 produce the moving advance and retreat of spiral shells with respect to running through screw along backwards rotation with this.

Comprehensive said structure is formed design, explains as follows with regard to the usage operation situation of the utility model:

Like Fig. 5, Fig. 6, shown in Figure 7; On elliptical stepper that the utility model is taken off uses; (annotate: adjustment mode such as aforementioned) through rod member 52 lift adjustments in the up-down of this elevating adjusting device 50 are highly different; And can change the priming point height and position of bent type coupled frame 60 drawing forks 30, and then reach the function and the purpose of adjustment pedal 41 front and back action stride; This partly please be further map 8, Fig. 9, shown in Figure 10; Lift adjustment through this elevating adjusting device 50 is highly different; Also be that W1, W2, W3 indicate distance (annotating: be to represent with the spacing that the circumflex branch of fork 30 is put bent type coupled frame 60 first connecting portions 63 among the figure); Can change priming point (like Fig. 8, Fig. 9, the B sign place shown in Figure 10) height and position of bent type coupled frame 60 drawing forks 30; So because the circumflex branch point distance change of this priming point and fork 30, so the swing amplitude of fork 30 will change relatively during priming, promptly Fig. 8, Fig. 9, Figure 10 angle differences such as 37 °, 41 °, 45 ° of sign respectively; Thereby further change treadle 40 together with the front and back of pedal 41 action stride, i.e. Fig. 8, Fig. 9, Figure 10 institute operating distance differences such as L1, L2, L3 of sign respectively; Because elevating adjusting device 50 positions of the utility model are the center section part of position at fork 30, meet human hands bending height position, so quite convenient and easy operation when user adjusts.

What be worth mentioning is that employing fork 30 links treadles 40 on whole swing of the utility model and the interlock architecture design, links the kenel of this fork 30 and driving wheel 22 crank portion 24 again with bent type coupled frame 60 more in addition; With this; It is moving to carry out elbow when this fork 30 and treadle 40 the two action smoothly; 60 of bent type coupled frames can play a kind of priming in the outside and have auxiliary effect of propping up again concurrently, make the action of overall architecture can reach comparatively steady and smooth and durable perfect condition.

The elliptical stepper structure of the utility model; Mainly through said body frame body, crank-type driver, two forks, two treadles, two bent type coupled frames and be located at the fork center section part and the innovation unique texture of the upright elevating adjusting device between the section top of bent type coupled frame is formed kenel design with pedal; Constitute when crank portion and revolved when moving by the driving wheel drive; Be able to through bent type coupled frame drawing fork swing; Can be highly different with this through the lift adjustment of this elevating adjusting device, change the priming point height and position of bent type coupled frame drawing fork, and then reach the function and the purpose of adjustment pedal front and back action stride; The adjustment structural design of the utility model has the simple and use operation convenience of member concurrently, and its whole swing and interlock framework employing fork binding treadle, links the kenel of fork and crank portion again with bent type coupled frame, can obtain steadily durable Practical Benefit.

The foregoing description though describe through specific term in the literary composition, can not limit the claim of the utility model in order to specify the utility model with this; Be familiar with the personage of this technical field and can be after the spirit of understanding the utility model and principle it be changed with modification and reach equivalent purpose, and these changes and modification, all should be covered by in the category that the claim scope defined.
