The specific embodiment

Consult Fig. 2, Fig. 3, Fig. 4, the preferred embodiment of elliptical machine of the present invention comprises a body 2, two slide assemblies 3, two pedal assemblies 4 and two linked components 5.

This body 2 have a pedestal 21, vertically-arranged at a dashboard bracket 22 of these pedestal 21 1 leading sections 211, be formed on a rail chair 23 of these pedestal 21 1 rearward end 212, but and turn mount on this pedestal 21 and two cranks 24 of contiguous these pedestal 21 leading sections 211.

These slide assemblies 3 have a sliding bar 31 and a U type ear seat 32 respectively.This sliding bar 31 is to form interlock with a front end 311 and this crank 24 pivots knot, and slides against on this rail chair 23 with a rear end 312.This U type ear seat 32 is formed in these sliding bar 31 1 end faces 313 and contiguous this rear end 312.

These pedal assemblies 4 have respectively steps on seat 41, one pivot 42 and a pedal 43.This steps on seat 41 is to be set in 32 of this ear seats with a front end 411, and this pivot 42 is to run through this ear seat 32 to step on seat 41 front ends 411 with this, makes this step on seat 41 and this sliding bar 31 pivots knot, and a rear end 412 can upper and lowerly be swung.This pedal 43 is to be installed in this to step on seat 41 end faces, uses for the sporter and steps on the station.

These linked components 5 have a swing arm 51 and a connecting rod 52 of mutual pivot joint respectively.This swing arm 51 is with its rough middle part and this dashboard bracket 22 pivots knot, and has and be formed on a top and can be for a handle 511 of sporter's grasping.This connecting rod 52 is to articulate with a front end and this swing arm 51 1 bottoms, and it is affixed to step on seat 41 1 lateral surfaces 413 with a rear end and this, and can draw this in swing process, to step on 41 rear end 412 upper and lower unsteady.In the present embodiment, be laterally to run through this connecting rod 52 respectively simultaneously with two connecting pins 53 to step on 41 (as shown in Figure 3) with this, step on seat 41 relative fixed so as to making this connecting rod 52 and this.

Ginseng Fig. 4～Fig. 7, when the user stand on these pedals 42, and when motion is trampled in the both feet circulation, these sliding bars 31 follow circular trace to rotate with front end 311 with these cranks 24 except meeting, reach with rear end 312 along these rail chair 23 linear slippages, ordering about this two pedal assembly 4 rotates relatively along predetermined elliptical orbit, and these carry out stepping on seat and 41 can forcing the connecting rod affixed with it 52 front and back shift reciprocatelies of elliptic motion, and these swing arm 51 swings of interlock, at this moment, because the rear end of these connecting rods 52 is to follow the elliptical orbit of stepping on seat 41, front end then is to be limited in (also can being designed to other form certainly on the pendulum track, for example the connecting rod front end can before and after be located at a slide rail of body slippingly), therefore, these connecting rods 52 can the periodic variation angle of inclination in when motion, and forces these to step on seat 41 to change the pedal 43 that drives on it with its angle and bow, face upward swing.When the minimum point of movement travel, the face of trampling of these pedals 43 is roughly parallel to ground (Fig. 6), then is low early and high after At All Other Times, and presents maximum depression (as Fig. 4) greatly when peak.

Whereby, these step on seat pedals 43 on 41 can be to be that benchmark moves along elliptical orbit with front end (toe end), these pedal 43 rear ends (heel end) then are to raise regularly, reduce, and keep pressing close to state with sporter's foot, whole process provides foot's one support effects of user, make the motion of foot comfortable naturally, be difficult for producing injury, and can meet ergonomics.

What deserves to be mentioned is, these step on seat 41 is to be hubbed on these sliding bars 31 with front end 411, can make rear end 412 have bigger amplitude of fluctuation, provide support effects to reach whole process, and because these step on seat 41 is the pressure of trampling that bears from top to bottom, therefore, provide the effect that supports except can these sliding bars 31 relative these stepping on seat 41, step in the processes that seat 41 floats at these, the connecting rod 52 that these are fixed with stepping on seat 41 also can form an auxiliary supporting role, whereby, make these step on the pivot part position stress equalization of seat 41, can avoid bearing the torsion of exertin, and can promote the smoothness when floating.
