nullIf Fig. 7-1 is to shown in Fig. 7-4，In motion process，Each linked component 60 can relative deflect with corresponding arrangement for guiding 40，And，Circulation rotating corresponding to aforementioned two cranks 30，Between groups of linked component 60 and arrangement for guiding 40, the angle (with the 5th pivot A5 as summit) can change between a maximum angle and a minimum angles repeatedly，Such as the first angle theta in figure，I.e. angle between fitting 62 bottom surface and abutting part 43 end face of arrangement for guiding 40 of linked component 60，Its angular dimension can change between maximum angle (corresponding roughly to aforementioned first corner dimension below the left-hand tread plate 61 in Fig. 7-2) and the minimum angles (aforementioned first corner dimension below the left-hand tread plate 61 corresponding roughly in Fig. 7-4) of about 10 degree of about 60 degree repeatedly，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 a preset space length (about 10 centimeters) it is separated by between fitting 62 bottom surface and abutting part 43 end face，In other words，It is movable that fitting 62 bottom pedal 61 can't affect the component under use state.
When do not use aforementioned elliptical exercise machine and to reduce its account for be empty time, user can stop under any position at crank 30 movable part such as grade, directly it is up overturn after releasing the lock-out state of guide rail bracket 20, locked by locking mechanism 70 again when arriving folding angle.Along with position before folding such as crank 30 movable part such as grade is different, or the factor such as the frictional resistance change between component, during guide rail bracket 20 is by use angular turn to folding angle, relative displacement between component is likely to 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, the most inherently present folding state as shown in Fig. 9 and Figure 11 (or with the most contrary form).Relevant aforementioned elliptical exercise machine can simple structure and shorter before and after under length, it is folded into folding state quickly and easily by use state, the technological means being directed to and principle substantially belong to the known techniques of aforementioned Chinese No. 200910162998.4 patent, the most no longer explain orally；But it is to be understood that the problem of the present invention essentially consists in the component shakedown problems solved after elliptical exercise machine folding, so the architectural feature in aforementioned known techniques is the constitutive requirements of the present invention the most completely.
During guide rail bracket 20 is by use angular turn to folding angle, the transition state as shown in Fig. 8-1 may be experienced, i.e., the wherein rearmost end of the most corresponding guide rail 21 of the rear end Relative sliding of an arrangement for guiding 40 (the left arrangement for guiding in such as figure) so that the gear arrived piece 42 inside roller 41 is stopped by the corresponding stopping part 24 of guide rail bracket 20 rear end and forms interference；The same time, with the arrangement for guiding 40 that guide rail bracket 20 produces previous intervention, yet suffering from 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 above 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 and left linked component 60 can corresponding reduce, gradually convergence 0 degree；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 and interfere.
Under different situations, during guide rail bracket 20 is by use angular turn to folding angle, the another kind of transition state as shown in Fig. 8-2 may be experienced, i.e., wherein linked component 60 (the left linked component in such as figure) a deflect to fitting 62 relative with corresponding arrangement for guiding 40 mutually abuts with abutting part 43 and forms interference；The same time, the arrangement for guiding 40 with linked component 60 produces previous intervention, yet suffer from a certain distance between the gear arrived piece 42 of its rear end and the corresponding stopping part 24 of guide rail bracket 20 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 be accordingly toward guide rail 21 rear end Relative sliding so that the gear arrived piece 42 inside roller 41 gradually approaches the corresponding stopping part 24 of guide rail bracket 20 rear end；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 gear arrived piece 42 of left arrangement for guiding 40 is stopped by the corresponding stopping part 24 of guide rail bracket 20 and forms another and interfere.
Must remind is, below it is only representational example explanation, that is, the folding process of aforementioned elliptical exercise machine is also possible to be different from above-mentioned condition, such as, before guide rail bracket 20 arrives folding angle, between any arrangement for guiding 40 and guide rail bracket 20 or and corresponding linked component 60 between previous intervention does not the most occur, or, at least one previous intervention once occurred during folding, but did not persistently keep to folding completing.Common phenomenon is, when the guide rail bracket 20 of aforementioned elliptical exercise machine is when using other angles between angle and folding angle, the 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 previous intervention between arrangement for guiding 40 and guide rail bracket 20, and arrangement for guiding 40 and linked component 60, will 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 gearing between aforementioned all components and pin down, 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 stopped by the corresponding stopping part 24 of guide rail bracket 20 rear end, form one first interference, aforementioned first interferes the rear end directly stoping aforementioned arrangement for guiding 40 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 correspondence to hinder front end edge first circular trace T1 of arrangement for guiding 40 to move towards the first rotation direction (counterclockwise in Fig. 9), equivalent hinders crank 30 to rotate towards the first rotation direction；And, with the arrangement for guiding 40 that guide rail bracket 20 produces the first interference, its abutting part 43 mutually can abut with the fitting 62 of corresponding linked component 60, form one second interference, aforementioned second interferes the rear end directly stoping arrangement for guiding 40 relatively close with the 5th pivot A5 for axle center with the rear end of linked component 60, and corresponding obstruction crank 30 rotates towards the second rotation direction () in Fig. 9 clockwise.
The principle that crank 30 the most both cannot rotate towards the first rotation direction, also cannot rotate towards the second rotation direction will be explained orally below by Figure 10-1, Figure 10-2, Figure 10-3 three figure.The schematic diagram that the relativeness of left crank 30, left arrangement for guiding 40, left linked component 60 and left wobble component 50 lower semisection that Figure 10-1 is based in Fig. 9 simplifies, Figure 10-2 and Figure 10-3 is based on the derivative fictitious state of Figure 10-1, wherein: crank 30 is relative to pivot (the i.e. second pivot) A2 of main frame body 10, and pivot (the i.e. the 3rd pivot) A3 of the relative main frame body 10 of wobble component 50, it is all relatively-stationary in three figures；Camber line T1' represents the possible movement locus of arrangement for guiding 40 and position (i.e. the first position of the arrangement for guiding 40) P1 of the mutual pivot joint of crank 30, is defined as the circular arc with the second pivot A2 as the center of circle；Camber line T2' represents the possible movement locus of linked component 60 and position (representing with the 4th pivot) A4 of the mutual pivot joint of wobble component 50, is defined as the circular arc with the 3rd pivot A3 as the center of circle；Ordinate T3' represents the possible movement locus in rear end (the i.e. second position) the P2 imagination of arrangement for guiding 40, and it is corresponding to guide rail 21 bearing of trend under folding state；Angle theta ' represent the angle with the 5th pivot A5 as summit between arrangement for guiding 40 rear end and linked component 60 rear end, although in definition with some difference of the first angle theta, but the two has corresponding relation.
If Figure 10-1 is to shown in Figure 10-3, assume that aforementioned first interference and second is interfered for the time being not exist, it is to say, assume that the second position P2 of arrangement for guiding 40 can be along track T3' again toward top offset for the time being, and the rear end of arrangement for guiding 40 can be the most relatively close with the rear end of linked component 60；Under above-mentioned hypothesis situation, if forcing crank 30 to be deflected 10 degree by the angle in Figure 10-1 towards the first rotation direction, the most aforementioned each component will necessarily become the state such as Figure 10-2, can be seen that under Bi compare that the rear end P2 of arrangement for guiding 40 is along track T3' toward top offset (note: it is only to illustrate that crank 30 deflects 10 degree, even if only deflection 1 degree, the rear end P2 of arrangement for guiding 40 also can corresponding above move)；Otherwise, if forcing crank 30 to be deflected 10 degree by the angle in Figure 10-1 towards the second rotation direction, the most aforementioned each component will necessarily become the state such as Figure 10-3, can be seen that under Bi compare the aforementioned angle theta between arrangement for guiding 40 and linked component 60 ' diminished (note: the same, even if 30, crank deflect 1 degree, angle theta ' also can correspondence diminish).Return to actual state, because the rear end of arrangement for guiding 40 (the i.e. second position) cannot be again toward top offset for fear of aforementioned first interference, so crank 30 in fact and cannot rotate towards the first rotation direction；Similarly, since the rear end of arrangement for guiding 40 cannot be the most relatively close for fear of aforementioned second interference with the rear end of linked component 40, so crank 30 the most also cannot rotate towards the second rotation direction.
And then, observe Fig. 9 and coordinate Figure 10-1 to Figure 10-3 can be with fast understanding following facts: based on the gearing between aforementioned all components and pin down, if left and right two cranks 30 have any spinning movement, the most left and right two arrangement for guiding 40, left and right two linked components 60 and left and right two wobble components 50 necessarily 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 necessarily have corresponding rotation, and other components also can corresponding displacement；So actual state is, because crank 30 cannot be carried out any rotation as already identified above, so two arrangement for guiding 40, two linked components 60 and two wobble components 50 cannot be carried out any displacement equally.
From the point of view of changing a viewpoint, under folding state as shown in Figure 9, act on the active force that the one of aforementioned all components correspond to make crank 30 rotate towards the first rotation direction (counterclockwise in figure), can make between left arrangement for guiding 40 and guide rail bracket 20, to produce aforementioned first interfere or increase the weight of aforementioned first interference, hinder crank 30 to rotate towards the first rotation direction；Otherwise, act on the active force that the one of above-listed all components correspond to make crank 30 rotate in figure clockwise towards the second rotation direction (), can make between left arrangement for guiding 40 and left linked component 60, to produce aforementioned second interfere or increase the weight of aforementioned second interference, hinder crank 30 to rotate towards the second rotation direction.
Understand via described above; elliptical exercise machine structure according to 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; it is not required to user's operation bidirectional; all components all can be in automatically cannot beat or the shakedown of sliding, it is ensured that 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 (be embodied in left and right two handles 51 under side-looking completely overlapped) relative to main frame body 10, the aforementioned elliptical exercise machine under folding state so can not only be allowed the most symmetrical attractive in appearance, and operation when symmetrical handle 51 beneficially user moves board and force.And when user to re-use aforementioned elliptical exercise machine, as long as guide rail bracket 20 to be down flipped back to the free state using angle, all components to be in the most again energy normal operation, use very convenient.Compared to prior art, the present invention is for the means stabilizing component are relatively easy, cost is relatively cheap, and having stable behavior is certain, and practicality is higher.
Additionally it is worth mentioning that, in the above-described embodiments, for producing the elastic material using rubber etc bottom the aforementioned second fitting 62 interfered, except solving to interfere the collision noise caused and scrape damage problem, prior purpose is to ensure that elliptical exercise machine is under folding state, aforementioned first interference and the second interference meeting and are deposited simultaneously, reach the effect above that all components are positioned completely.In details of the words, even if the know-why according to the present invention is appropriately designed, because the making precision of component, assembly precision, or deformation in the future, the pivot practice problem being difficult to avoid that such as lax, (the note: although be " location " when guide rail bracket 20 is positioned at folding angle, but actually guide rail bracket 20 relative to main frame body 10 may still have 1,2 degree allow deflection), it may happen that support the most mutually for constituting relative two positions of the first interference, but having minim gap between relative two positions constituting the second interference, vice versa；It is to say, each component is likely to be of unconspicuous activity nargin (but the most still symbolic animal of the birth year is to stable)；If relative two positions being used for constituting interference that at least one of which is interfered in the first interference and second include elastic material, 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, abutting part 43 end face of arrangement for guiding 40 is first touched in fitting 62 bottom surface being probably linked component 60, subsequently the gear arrived piece 42 at arrangement for guiding 40 and then touch guide rail bracket 20 stopping part 24 of short duration during, the bottom of fitting 62 can produce the flat contracting of elasticity of correspondence, make aforementioned first to interfere and second interfere can simultaneously and deposit.
nullThe upperseat concept of the technological means of the present invention is，Based on guide rail bracket、Crank、Arrangement for guiding、Linked component、Gearing between the components such as wobble component and pining down，When aforementioned guide rail bracket is positioned at folding angle，One of them of aforementioned all components can produce one first interference with another，Aforementioned first interferes correspondence to hinder aforementioned crank to rotate towards a wherein rotation direction，And，One of them of aforementioned all components can produce one second interference (note: produce two components of the second interference with another，With two components producing the first interference，A repetition may be had between two groups，Such as left arrangement for guiding 40 in Fig. 9)，Aforementioned second interferes correspondence to hinder aforementioned crank to rotate towards another rotation direction，Interfere thus by first and the second interference limits 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, being probably and can mutually abut the predetermined position of (the such as interference 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 and mutually abut (the such as interference between gear arrived piece 42 and stopping part 24) or other any can directly or indirectly hinder crank towards the component interference that wherein a rotation direction rotates, but premise is previous intervention is the gearing between Component-Based Development and pins down and can produce and elimination by nature.
nullIn other words，The first interference and the second interference in the present invention are not limited to the taken off form of above-described embodiment，For example，It is intended to equally hinder the crank 30 in Fig. 9 to rotate towards the second rotation direction () in figure clockwise，Except " linked component 60 making mutual pivot joint produces interference to stop the most relative deflection with the predetermined position of arrangement for guiding 40 "，Also employing " linked component 60 making mutual pivot joint produces with the predetermined position of wobble component 50 and interferes to stop the most relative deflection " can be changed，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)，Between the rightest linked component 60 with right wobble component 50, the second angle theta 2' (with the 4th pivot A4 as summit) can corresponding diminish，So the aforementioned fitting 62 bottom pedal 61 can be need not 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 mutually can abut with another corresponding position just，Directly stop linked component 60、Both wobble components 50 close relative to deflection (i.e. stoping the second angle theta 2' in Figure 12 to diminish)，Corresponding obstruction crank 30 rotates towards the second rotation direction.Understanding refering to Fig. 7-1 to Fig. 7-4, 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 can change between a maximum angle and a minimum angles repeatedly；And under folding state, the second angle between one of which linked component 60 and wobble component 50 can be less than second angle (note: in such as Figure 12, the second angle theta 2' on the right side of board is less than the second angle theta 2 on the left of board in Fig. 9) of another group, and less the second angle of at least a part of which angle can be less than aforementioned minimum angles, and previous intervention is i.e. between linked component 60 and the wobble component 50 betiding and constituting aforementioned less second angle.
Similar viewpoint, in a state of use, corresponding to the circulation rotating of two cranks 30, the distance between gear arrived piece 42 and the stopping part 24 of guide rail bracket 20 rear end of each arrangement for guiding 40 rear end can change between a maximum spacing and a minimum spacing repeatedly, and aforementioned minimum spacing is more than 0；And under folding state, wherein the distance between gear arrived piece 42 and the stopping part 24 of guide rail bracket 20 of an arrangement for guiding 40 can become 0, i.e. the two mutually abuts, and forms aforementioned first and interferes.
Furthermore, the first interference or second in the present invention is interfered between the predetermined position being likely to occur in any two components that can be movable relatively, comprise between arrangement for guiding and wobble component, between linked component and main frame body ... etc., it is not limited in structure mutually pivot joint or has between two components being directly connected to.
