As shown in Fig. 7-1 to Fig. 7-4, in motion process, each linked component 60 can deflect relatively with corresponding arrangement for guiding 40, and, corresponding to the circulation rotating of aforementioned two cranks 30, between linked component 60 in groups and arrangement for guiding 40, the angle of (with Wushu axle A5 for summit) repeatedly can change between a maximum angle and a minimum angles, such as, the first angle theta in figure, namely the angle between fitting 62 bottom surface of linked component 60 and abutting part 43 end face of arrangement for guiding 40, its angular dimension repeatedly can change between the maximum angle (roughly corresponding to aforementioned first corner dimension below the left-hand tread plate 61 in Fig. 7-2) of about 60 degree and the minimum angles (roughly corresponding to aforementioned first corner dimension below the left-hand tread plate 61 in Fig. 7-4) of about 10 degree, wherein, even if when linked component 60 is relative with arrangement for guiding 40 deflect to the first angle theta present minimum angles time, still to be separated by between fitting 62 bottom surface and abutting part 43 end face a preset space length (about 10 centimeters), in other words, the component that fitting 62 bottom pedal 61 can't affect under using state is movable.
When do not use aforementioned elliptical exercise machine and to reduce its account for put space time, user can stop under any position at movable part such as crank 30 grade, directly it is up overturn after removing the lock-out state of guide rail bracket 20, locked by locking mechanism 70 again when arriving folding angle.Along with the position of movable part such as crank 30 grade before folding is different, or the factor such as the frictional resistance change between component, turn in the process of folding angle at guide rail bracket 20 by use angle, relative displacement between component also may be not quite alike, such as certain folding may experience the transition state as shown in Fig. 8-1, and another folding may experience the another kind of transition state as shown in Fig. 8-2, but regardless of folding process, finally inherently present the folding state (or form heterochiral with it) as shown in Fig. 9 and Figure 11.About aforementioned elliptical exercise machine can under simple structure and shorter anterior-posterior length, folding state is become quickly and easily by using state folding, the technological means wherein related to and principle belong to the known techniques of aforementioned Chinese No. 200910162998.4 patent substantially, no longer explain orally herein; But it is to be understood that problem of the present invention is mainly to solve the component shakedown problems after elliptical exercise machine folding, so the architectural feature in aforementioned known techniques is not constitutive requirements of the present invention completely.
Turn in the process of folding angle at guide rail bracket 20 by use angle, the transition state as shown in Fig. 8-1 may be experienced, namely, wherein the rear end Relative sliding of an arrangement for guiding 40 (the left arrangement for guiding in such as figure) is to the rearmost end of corresponding guide rail 21, and the corresponding stopping part 24 making the gear arrived piece 42 inside roller 41 be subject to guide rail bracket 20 rear end stops and forms interference; The same time, produce the arrangement for guiding 40 of previous intervention with guide rail bracket 20, still there is a certain distance between its abutting part 43 with the fitting 62 of corresponding linked component 60, in other words, the first angle theta under aforementioned definitions is still greater than 0 degree.May be as follows by the subsequent process of Fig. 8-1 to Fig. 9: along with guide rail bracket 20 continues to transfer folding angle to, the rear end of left arrangement for guiding 40 is locked on the rearmost end of left rail 21 always, and the first angle theta between left arrangement for guiding 40 with left linked component 60 can correspondingly reduce, convergence 0 degree gradually; When guide rail bracket 20 arrives folding angle, the previous intervention between left arrangement for guiding 40 and guide rail bracket 20 still exists, and the fitting 62 of left linked component 60 mutually abuts with the abutting part 43 of left arrangement for guiding 40 and forms another interferes.
Under different situations, turn in the process of folding angle at guide rail bracket 20 by use angle, the another kind of transition state as shown in Fig. 8-2 may be experienced, that is, wherein a linked component 60 (the left linked component in such as figure) deflect to fitting 62 relative to corresponding arrangement for guiding 40 mutually abuts with abutting part 43 and is formed and interfere; The same time, producing the arrangement for guiding 40 of previous intervention with linked component 60, still there is a certain distance with between the corresponding stopping part 24 of guide rail bracket 20 rear end in the gear arrived piece 42 of its rear end.May be as follows by the subsequent process of Fig. 8-2 to Fig. 9: along with guide rail bracket 20 continues to transfer folding angle to, the fitting 62 of left linked component 60 is connected on the abutting part 43 of left arrangement for guiding 40 always, and the rear end of left arrangement for guiding 40 can, accordingly toward guide rail 21 rear end Relative sliding, make the gear arrived piece 42 inside roller 41 approach the corresponding stopping part 24 of guide rail bracket 20 rear end gradually; When guide rail bracket 20 arrives folding angle, the previous intervention between left linked component 60 and left arrangement for guiding 40 still exists, and the corresponding stopping part 24 that the gear arrived piece 42 of left arrangement for guiding 40 is subject to guide rail bracket 20 stops and forms another and interfere.
What must remind is, below be only representational example explanation, that is, the folding process of aforementioned elliptical exercise machine is also likely different from above-mentioned condition, such as, before guide rail bracket 20 arrives folding angle, any arrangement for guiding 40 with between guide rail bracket 20 or and corresponding linked component 60 between all not there is previous intervention, or at least one previous intervention once occurred in folding process, but do not continue to be retained to folding and complete.Common phenomenon is, when other angles between use angle and folding angle of the guide rail bracket 20 of aforementioned elliptical exercise machine, at most only can there is a kind of previous intervention in the same time, in other words, before guide rail bracket 20 arrives folding angle, previous intervention between arrangement for guiding 40 and guide rail bracket 20, and the previous intervention between arrangement for guiding 40 and linked component 60, can not occur simultaneously.
As shown in Fig. 9 and Figure 11, when guide rail bracket 20 arrives and is positioned at folding angle, based on the interlock between aforementioned all components and pin down, the corresponding stopping part 24 that wherein the gear arrived piece 42 of arrangement for guiding 40 (the left arrangement for guiding in a such as figure) rear end can be subject to guide rail bracket 20 rear end stops, form one first to interfere, aforementioned first interferes the rear end of the directly aforementioned arrangement for guiding 40 of prevention along the bearing of trend of guide rail 21 away from guide rail front end (note: in the present embodiment, the baffle plate 23 of guide rail bracket 20 rear end separately can prevent the rear end of arrangement for guiding 40 now from toppling over toward board front), aforementioned first interferes the corresponding front end edge first circular trace T1 of arrangement for guiding 40 that hinders to move towards the first rotation direction (counterclockwise in Fig. 9), the equivalent crank 30 that hinders rotates towards the first rotation direction, and, the arrangement for guiding 40 of the first interference is produced with guide rail bracket 20, its abutting part 43 can abut mutually with the fitting 62 of corresponding linked component 60, form one second to interfere, directly the rear end of prevention arrangement for guiding 40 and the rear end of linked component 60 are with Wushu axle A5 for axle center is relative close in aforementioned second interference, and the corresponding crank 30 that hinders rotates towards the second rotation direction () in Fig. 9 clockwise.
Below by explained orally by Figure 10-1, Figure 10-2, Figure 10-3 three figure crank 30 in the above-described state both cannot towards first rotation direction rotate, also cannot towards second rotation direction rotate principle.Figure 10-1 is the schematic diagram of the relativeness simplification according to left crank 30, left arrangement for guiding 40, left linked component 60 and left wobble component 50 lower semisection in Fig. 9, Figure 10-2 and Figure 10-3 is according to the derivative fictitious state of Figure 10-1, wherein: crank 30 is relative to pivot (i.e. the second pivot) A2 of main frame body 10, and pivot (i.e. the 3rd pivot) A3 of the relative main frame body 10 of wobble component 50, be all relatively-stationary in three figure; Camber line T1' represents the possible movement locus of arrangement for guiding 40 and crank 30 position (i.e. the first position of the arrangement for guiding 40) P1 of pivot joint mutually, the circular arc that to be defined as with the second pivot A2 be the center of circle; Camber line T2' represents the possible movement locus of linked component 60 and wobble component 50 position (representing with the 4th pivot) A4 of pivot joint mutually, the circular arc that to be defined as with the 3rd pivot A3 be the center of circle; Ordinate T3' represents the possible movement locus in rear end (i.e. the second position) the P2 imagination of arrangement for guiding 40, and it corresponds to guide rail 21 bearing of trend under folding state; Angle theta ' represent the angle being summit with Wushu axle A5 between arrangement for guiding 40 rear end and linked component 60 rear end, although in definition with some difference of the first angle theta, the two has corresponding relation.
As shown in Figure 10-1 to Figure 10-3, suppose that aforementioned first interference and the second interference do not exist for the time being, that is, suppose that the second position P2 of arrangement for guiding 40 can along track T3' again toward top offset for the time being, and the rear end of arrangement for guiding 40 can be relative close again with the rear end of linked component 60; Under above-mentioned hypothesis situation, if force crank 30 to deflect 10 degree by the angle in Figure 10-1 towards the first rotation direction, then aforementioned each component will inevitably become the state as Figure 10-2, can find out relatively that the rear end P2 of arrangement for guiding 40 is along track T3' toward top offset (note: it is only illustrate that crank 30 deflects 10 degree, even if only deflect 1 degree, the rear end P2 of arrangement for guiding 40 also can correspondence be moved); Otherwise, if force crank 30 to deflect 10 degree by the angle in Figure 10-1 towards the second rotation direction, then aforementioned each component will inevitably become the state as Figure 10-3, can find out relatively aforementioned angle theta between arrangement for guiding 40 and linked component 60 ' diminish (note: the same, even if 30, crank deflection 1 degree, angle theta ' also can correspondence diminish).Get back to actual state, because the rear end of arrangement for guiding 40 (i.e. the second position) interfere for fear of aforementioned first cannot again toward top offset, so crank 30 in fact and cannot rotate towards the first rotation direction; Similarly, because interfere for fear of aforementioned second with the rear end of linked component 40 cannot be relative close again, so crank 30 also cannot rotate towards the second rotation direction in fact in the rear end of arrangement for guiding 40.
And then, observe Fig. 9 and coordinate Figure 10-1 to Figure 10-3 can be true below fast understanding: based on the interlock between aforementioned all components and pin down, if left and right two cranks 30 have any spinning movement, then left and right two arrangement for guiding 40, left and right two linked components 60 and left and right two wobble components 50 must have corresponding displacement, otherwise, if any one in two arrangement for guiding 40, two linked components 60 and two wobble components 50 has any displacement, then two cranks 30 must have corresponding rotation, and other components also can corresponding displacement; So actual state is, because crank 30 cannot carry out any rotation as mentioned above, so two arrangement for guiding 40, two linked components 60 and two wobble components 50 cannot carry out any displacement equally.
Change a viewpoint, under folding state as shown in Figure 9, act on one of aforementioned all components corresponding to the active force making crank 30 rotate towards the first rotation direction (counterclockwise in figure), can make to produce between left arrangement for guiding 40 and guide rail bracket 20 aforementioned first to interfere or increase the weight of aforementioned first and interfere, hinder crank 30 to rotate towards the first rotation direction; Otherwise, act on one of above-listed all components corresponding to the active force making crank 30 rotate towards the second rotation direction () in figure clockwise, can make to produce between left arrangement for guiding 40 and left linked component 60 aforementioned second to interfere or increase the weight of aforementioned second and interfere, hinder crank 30 to rotate towards the second rotation direction.
Known via above explanation; according to the elliptical exercise machine structure of the above-mentioned preferred embodiment of the present invention; when guide rail bracket 20 is positioned at folding angle; the components such as left and right two cranks 30, left and right two arrangement for guiding 40, left and right two linked components 60 and left and right two wobble components 50 all can cannot move because of mutually pining down; in other words; while aforementioned elliptical exercise machine becomes folding state; do not need user's operation bidirectional; all components all can be in automatically cannot the shakedown of beat or slippage, guarantees security when board is shelved and moved.And in the above-described embodiments, when elliptical exercise machine is locked in folding state, such as shown in Fig. 9, left and right two wobble components 50 under side-looking can be positioned at identical angle (being embodied in left and right two handles 51 completely overlapping under side-looking) relative to main frame body 10, the aforementioned elliptical exercise machine under folding state so can not only be allowed comparatively symmetrical attractive in appearance, and symmetrical handle 51 is conducive to operation when user moves board and force.And when user will re-use aforementioned elliptical exercise machine, as long as guide rail bracket 20 down to be overturn back use angle, all components are just in again the free state of energy normal operation, use very convenient.Compared to prior art, the present invention is relatively simple for the means of stable component, cost is relatively cheap, and having stable behavior is certain, and practicality is higher.
It is worth mentioning that in addition, in the above-described embodiments, for generation of the elastic material adopting rubber and so on bottom the aforementioned second fitting 62 of interfering, interfere the collision noise that causes except solving and scrape damage problem, prior object is to guarantee that elliptical exercise machine is under folding state, aforementioned first interference and the second interference are understood simultaneously and deposit, and reach all components by the above-mentioned effect of locating completely.In details of the words, even if suitably design according to know-why of the present invention, because the making precision of component, assembly precision, or distortion in the future, pivot such as to relax at the practice problem being difficult to avoid, (the note: although be " location " when guide rail bracket 20 is positioned at folding angle, but in fact guide rail bracket 20 relative to main frame body 10 may still have 1,2 degree allow deflection), relative two positions that may occur for forming the first interference are supported really mutually, but for form the second interference relative two positions between have minim gap, vice versa, that is, each component may have unconspicuous activity nargin (but on the whole still symbolic animal of the birth year to stable), if first interfere and second interfere wherein at least one include elastic material for relative two positions forming interference, foregoing problems can be solved simply, such as, in the above-described embodiments, the final stage of folding angle is turned at guide rail bracket 20, it may be abutting part 43 end face that arrangement for guiding 40 is first touched in fitting 62 bottom surface of linked component 60, and then touch in the gear arrived piece 42 of arrangement for guiding 40 subsequently in the of short duration process of stopping part 24 of guide rail bracket 20, the bottom of fitting 62 can produce the corresponding flat contracting of elasticity, aforementioned first is made to interfere and second interfere can simultaneously and deposit.
The upperseat concept of technological means of the present invention is, based on guide rail bracket, crank, arrangement for guiding, linked component, interlock between the components such as wobble component and pining down, when aforementioned guide rail bracket is positioned at folding angle, one of them meeting of aforementioned all components produce one first with another and interfere, aforementioned first interferes the aforementioned crank of corresponding obstruction towards a wherein rotation direction rotation, and, one of them meeting of aforementioned all components produce one second with another and interfere (note: produce the second two components of interfering, two components of interfering with generation first, a repetition may be had between two groups, such as, left arrangement for guiding 40 in Fig. 9), aforementioned second interferes the aforementioned crank of corresponding obstruction to rotate towards another rotation direction, so interfered by the first interference and second and limit the aforementioned crank mutually affected with joint efforts, arrangement for guiding, linked component, the mobility of wobble component etc.The generation form of each previous intervention, may be that the predetermined position that can mutually abut (interference such as between fitting 62 with abutting part 43) or specific two components that can be movable relatively relative to the predetermined position of specific two components deflected abuts (such as keeping off the interference between arrived piece 42 and stopping part 24) or other any component interferences that can directly or indirectly hinder crank to rotate towards a wherein rotation direction mutually, but prerequisite be previous intervention is interlock between Component-Based Development and pins down and can produce and elimination by nature.
In other words, in the present invention first interferes and the second interference is all not limited to form that above-described embodiment is taken off, for example, to hinder the crank 30 in Fig. 9 to rotate towards the second rotation direction () equally in figure clockwise, except " make the linked component 60 of mutual pivot joint and the predetermined position of arrangement for guiding 40 produce and interfere to stop specific relative deflection ", also can change employing " linked component 60 of mutual pivot joint and the predetermined position of wobble component 50 to be produced and interferes to stop specific relative deflection ", in detail, refer to Figure 12 (i.e. the opposite sides of folding state shown in Fig. 9), if because crank 30 rotates towards the second rotation direction (counterclockwise in Figure 12), then between right linked component 60 with right wobble component 50, the second angle theta 2' of (with the 4th pivot A4 for summit) can correspondingly diminish, so the aforementioned fitting 62 bottom pedal 61 can not be needed in another embodiment of the invention, replace and similar fitting is installed in the front end of linked component 60 or the nearly bottom position of wobble component 50, when guide rail bracket 20 arrives folding angle, one of them fitting of linked component 60 and wobble component 50 can abut with another corresponding position just mutually, direct prevention linked component 60, both wobble components 50 are deflection close (namely stoping the second angle theta 2' in Figure 12 to diminish) relatively, the corresponding crank 30 that hinders rotates towards the second rotation direction.Consult Fig. 7-1 to Fig. 7-4 known, in a state of use, corresponding to the circulation rotating of two cranks 30, aforementioned second angle between each linked component 60 and corresponding wobble component 50 also repeatedly can change between a maximum angle and a minimum angles; And under folding state, the second angle wherein between one group of linked component 60 and wobble component 50 can be less than another second angle organized (note: the second angle theta 2' in such as Figure 12 on the right side of board is less than the second angle theta 2 in Fig. 9 on the left of board), and the second angle that wherein at least angle is less can be less than aforementioned minimum angles, and previous intervention be namely betide form aforementioned less second angle between linked component 60 and wobble component 50.
Similar viewpoint, in a state of use, corresponding to the circulation rotating of two cranks 30, the distance between the gear arrived piece 42 of each arrangement for guiding 40 rear end and the stopping part 24 of guide rail bracket 20 rear end repeatedly can change between a maximum spacing and a minimum spacing, and aforementioned minimum spacing is greater than 0; And under folding state, the distance wherein between the gear arrived piece 42 of an arrangement for guiding 40 and the stopping part 24 of guide rail bracket 20 can become 0, namely the two abuts mutually, forms aforementioned first and interferes.
Moreover, in the present invention first interferes or the second interference may occur between the predetermined position of any two components that can be movable relatively, comprise between arrangement for guiding and wobble component, between linked component and main frame body ... etc., be not limited to mutual pivot joint in structure or have between two components that directly connect.
