Below in conjunction with drawings and Examples the utility model is elaborated:

As Fig. 3, Fig. 4 and shown in Figure 5, elliptical exercise machine preferred embodiment of the present utility model, comprise a frame (frame) 10, one is rotatably mounted in the left side of this frame 10, right crank (left crank, right crank) 20,20 ', one is arranged at the left side of this frame 10, right slide rail (left rail, right rail) 30,30 ', one with this left side, right crank 20,20 ' is and connects slidably and be subjected to this left side, right slide rail 30, the left side of 30 ' guiding, right extension rod (left extension link, rightextension link) 40,40 ', one is arranged on this frame 10 and can be with respect to the left side of these frame 10 reciprocally swingings movably, right connector (left connectormember, right connector member) 50,50 ' and one is articulated in this left side, right connector 50,50 ' with this left side, right extension rod 40, left side between 40 ', right treadle (left foot link, right foot link) 60,60 '.

This frame 10 is to extend along a length direction X, and has pedestal 12 and that a underframe spare 11, that is I shape is installed in this underframe spare 11 1 rearward end and be erected at montant spare 13 at this underframe spare 11 1 leading sections with respect to this pedestal 12.This pedestal 12 is that ovalize is plate-like, and the left and right end face 121,122, with opposing setting perpendicular to left and right end face 121,122 and position at shared crank axis (common crank axis) L, a corresponding length direction X of these pedestal 12 central authorities and the major axis I by this shared crank axis L and one perpendicular to this major axis I and the minor axis II by this shared crank axis L, the length of this major axis I is greater than this minor axis II (see figure 6).

This left side crank 20 and right crank 20 ' they are that to make rectangular hollow shaft-like, apart 180 degree and being rotatably mounted on this pedestal 12, and can be around this shared crank axis L with respect to these pedestal 12 rotations.

This left side slide rail 30 and right slide rail 30 ' are to be arranged with privately and symmetrically on this left side mutually, right side 121, on 122, its grade respectively has an interior rail level (inner rail surface) 31 around this shared crank axis L, 31 ', one is centered around rail level 31 in this, 31 ' outside outer rail level (outer rail surface) 32,32 ' and one in this rail level 31,31 ' with outer rail level 32, operating path between 32 ' (movingpath) 33,33 ', this operating path 33,33 ' is to be non-circular (non-circular), the selection of present embodiment the best is to be avette, corresponding frame 10 front ends and position are less in the radius of curvature of this major axis I one end, and corresponding frame 10 rear ends and position are bigger in the radius of curvature of this major axis I other end.

This left side extension rod 40 and right extension rod 40 ' are rectangular shaft-like, and respectively has one first connecting portion 41,41 ' (first connecting portion), one second connecting portion (second connecting portion) 42,42 ' and 1 the 3rd connecting portion (third connecting porti on) 43,43 ', aforementioned first connecting portion 41,41 ' respectively with this left side, right crank 20,20 ' radially pegs graft slidably, aforementioned second connecting portion 42,42 ' is between first connecting portion 41, the 41 ' and the 3rd connecting portion 43, between 43 ', and all be pivoted with a roller (roller) 44,44 ', aforementioned roller 44,44 ' is slidedly arranged on this left side respectively, right slide rail 30,30 ' operating path 33, on 33.

This left side connector 50 and right connector 50 ' are that branch is located at this montant spare 13 both sides, and respectively have a handle section 52 that is hubbed on the last centring point 51 on this montant spare 13,51 ', centring point 51, a 51 ' top on this, 52 ' and one is provided with and the following centring point 53,53 ' of position this on centring point 51,51 ' below opposite with this handle section 52,52 ', aforementioned under centring point 53,53 ' can be along this length direction X with respect to these frame 10 reciprocally swingings.

This left side treadle 60 and right treadle 60 ' respectively have one and are articulated in the 3rd connecting portion 43,43 ' first end 61,61 ', and are articulated in this time pivoting point 53,53 ' the second end 62,62 ' and and are installed in pedal 63,63 ' on contiguous this first end 61,61 '.

Assembly for convenience, above-mentioned pedestal 12 also has two to be located at apical margin and to be through to this left and right slide rail 30,30 ' perforate 123,124 and the shrouding 125 of the aforementioned perforate 123,124 of a sealing by the outside, and aforementioned perforate the 123, the 124th wears and is slidedly arranged on respectively in this left and right slide rail 30,30 ' operating path 33,33 ' for aforementioned roller 44,44 '.

Again as shown in Figure 6, when operator's foot tramples at pedal 63, on 63 ', both hands are held in this left side, right connector 50,50 ' handle section 52, on 52 ', and when making trample action, spur handle section 52 auxiliaryly, then utilize roller 44,44 ' at operating path 33, circular flow in 33 ', and to should major axis I and the length variations of minor axis II, this left side, right extension rod 40,40 ' will be with respect to this left side, right crank 20,20 ' produces and to extend radially or the action of retraction, and shown in solid line and dotted line, this left side,

right crank

20,20 during corresponding to minor axis II, this left side, right extension rod 40,40 ' with respect to this left side, right crank 20,20 ' retraction is to the shortest state, for another example shown in the imaginary line, this left side,

right crank

20,20 during corresponding to major axis I, this left side, right extension rod 40,40 ' with respect to this left side, right crank 20,20 ' extend out to the longest state, and to state that should major axis I two ends the time, this left side, right connector 50,50 ' can be rocked to a left side respectively, limit on the right-right-hand limit.And for example shown in Figure 7, when this left and right treadle of ongoing operation 60,60 ' and this left and right connector 50,50 ' time, just can reach and trample the body-building purpose, and can produce the running orbit of an ovalize.

Therefore, elliptical exercise machine of the present utility model not only can produce elliptical orbit (elliptical path), and when operation, the effect that utilizes non-circular operating path 33,33 ' setting and this left and right extension rod 40,40 ' can stretch out retraction with respect to this left and right crank 20,20 ', just can strengthen the elliptical orbit scope, and make the user that the amplitude that strides also strengthens relatively, can produce preferable movement effects, also do not need to strengthen body.

What deserves to be mentioned is that this left and right connector 50,50 ' also can adopt the roller kenel according to the existing elliptical exercise machine of Fig. 2, also can reach identical effect.
