On the left and one body, each frame has a rigid connection—the shackles are respectively suspended at the bottom ends of the left and right longitudinal column segments, corresponding to the left and the vertical bar segments and the bottom of the crossbar segment. The rod segment is pivotally connected by the wheel of the = at the fixed end of the bone to the front end of the skeleton, and the top end extends forward, and the instrument of the front motive is raised or lowered, so that although the drive is broken, the top end of the cantilever is transported along the elliptical Corresponding to the skeleton, the corresponding trajectory at the rear end of the crossbar segment is shifted by the motion track of the pedal and the pedal, so that the cantilever bottom τ is changed compared to the earlier swing arm type: degree: change. 3_32 patent), the front uncovering the motive of the exercise machine (for example, Taiwan, the resistance point is between the fulcrum and the point of application, forming a second type of rod), so that the drive device can use the pre-cost of power greater than the resistance arm) Save energy and facilitate design. However, the 2 motor 'in order to reduce the advantage of obtaining the "saving effort" 201127445, but it is also accompanied by the "time-consuming" shortcoming, that is, because the front end of the cup section of the frame body (ie, the point of application of the driving device) and the bottom end of the longitudinal rod section The linear distance between the fulcrums of the frame is significantly larger than the linear distance between the rear end of the cross-section (ie, the resistance point of the suspension cantilever) and the bottom end of the longitudinal section (the aforementioned fulcrum), so the displacement rate of the resistance point Will be significantly smaller than the displacement rate of the point of application (Note: the angular velocity is equal to the 'but the difference is the radius', so the moving distance is different), in other words, if the tip of the cantilever is displaced by a unit distance, the aforementioned driving device may have to The front end of the driving crossbar segment is displaced by two unit distances, so that the user feels that the reaction time is longer when adjusting the pedal running slope. On the other hand, the pedal trajectory can be adjusted between the preset maximum and minimum slopes, and the front end of the machine requires a long space for the front end of the frame to be displaced, forming a design limitation. Furthermore, 'the front elliptical exercise machine adjusts the pedal trajectory by changing the angle of the frame'. When the trajectory exhibits the maximum and minimum inclination, the angle of the cross-section of the frame also has a significant difference (for example, from a general level to a depression angle of twenty degrees). ). Wherein the rear end top surface of the crossbar section is designed to be accessible to the user when the pedal is up and down, and as the front end of the crossbar section is lifted and lowered, the slope of the top surface is also significantly changed. The posture and feel of the user who will help the part are not the same every time, which is less than ideal. In addition, the front ends of the crossbar segments of the left and right frames are coupled to each other and screwed onto a longitudinal screw of the driving device, the bottom end of the screw is pivotally connected to the skeleton, and the top end is an unsupported free end, when the screw is driven by the motor. When driving forward or reverse, the front end of the crossbar section is raised or lowered along the axial direction of the screw, and the axial direction of the screw is also slightly deflected by the bottom end (the front end of the crossbar section must be centered on the aforementioned fulcrum) . In this structure, the front end weight of the left and right two frames is 201127445 == the screwing part and the bottom end pivoting part of the rod ί are easy to cause structural damage or inferior γ movability and smoothness. [Summary of the Invention] The round can be adjusted to the pedals and the user's adjustment needs. In addition, it can respond to the round in a short time. ί: The short 4 of the Ming, the design of the more flexible ^ required component displacement space is more oblique than the round = Ming supply - a kind of adjustable pedal trajectory There is a part for the user to catch up and down the pedal, and the angle of the = position is not significantly changed due to the adjustment of the pedal pedal: the clear 4 provides a bribe for adjusting the pedal trajectory, and Structure (4):: The coffee machine when the pedal track is used to achieve the above purpose, the adjustable pedal track provided by the present invention = the circular motion machine comprises: - the main frame body; - the crank mechanism, which is arranged in the main frame body End, with left and right cranks; 纟 and right two swing arms, each having a front end that can be swung back and forth; 纟 'right two support rods, each having front and rear ends, and the front end is pivotally connected to the corresponding crank The end, the rear end or the middle portion is pivotally connected to the swinging end of the corresponding swing arm; the left and right pedals are respectively supported by the two support rods 201127445, and are guided to move on a closed track; the feature is: the second pendulum The arms are respectively suspended on the left and right side frames, and each side frame has a first The first rod body of the body and the second rod body has a top end and a bottom end, and the bottom end is pivotally connected to the bottom rear end of the main frame body by the top end yoke front and rear yaw, and each second rod body The front end and the rear end are respectively connected to the top end of the corresponding rod body, and the front end is connected to a driving device at the front end of the main frame body, and the driving device can drive the front end of the second rod body to advance or retreat The portion of the side frame that is suspended by the swing arm is correspondingly displaced along a reciprocating track between a front end point and a rear end point, so that the long axial slope of the closed track is correspondingly increased or decreased. Preferably, the swing arm is suspended at the end or near end portion of the second rod body, or is pivotally connected to the top end or the near end portion of the first rod body. The amount of displacement of the front end of the body, that is, the displacement of the swing arm __, the (four) plate = the speed of change is relatively fast, and the displacement required for the front end of the side frame is shorter. In addition, because of the second rod The self-state's illusion angle is roughly the same, so if the Gansu ^ top surface is designed to catch the helper (4) Positioning ^ Capture the part 'not affected by the pedal trajectory.

The swaying end of the provincial ridge hand is pivotally connected, and the following: the middle (four) position and the other arm of the arm, the same can guide the principle and use method of the elliptical exercise machine of the present invention before the == indirect support Basically, I know τμ κ and hand movements (for example, before the Taiwan _08 machine, so I will not repeat them in this case. 'Khan case') is no difference J2 [S1 201127445, when the user is based on personal needs, or machine The table automatically adjusts the closed trajectory of the pedal (60) according to the preset path ^'. The driving device (7) is controlled to drive the front ends of the left and right second rods (21) forward or backward by a predetermined distance, so that the left and right side frames (^°) are synchronously moved to the left. The position of the hanging end of the right second swing arm (30) (ie, the second axis (A 3 )) is moved forward and backward along the second reciprocating track, and when the hanging end is displaced forward When the swing arm (3〇) is placed at the end of the front lu = arc open ^ track and the pedal (6 〇) of the aforementioned sealing track (the slope of the 〇 will gradually become smaller, and conversely, when the aforementioned suspension end is displaced backward The slope of the arc and the inclination (elevation angle) of the obstruction (C) will gradually increase, thereby adjusting the shape and difficulty of the leg movement. Compared with the elliptical motion of the same type, the advantages and advantages of the present invention As follows: 1. Regardless of whether the suspension end of the swing arm is pivotally connected to the second shaft of the side frame (any: energy position) or the first rod body (top or near top end), after adjusting the pedal track, the aforementioned pivotal connection The displacement rate of the part will be approximately equal to the front displacement of the second rod body. In other words, the displacement domain is set to the second rod body. The front-rear displacement will directly reflect the front-back displacement of the swing arm suspension end. Therefore, under the same motor speed and phase, the adjustment action of the present invention is relatively fast. Second, the same swing position of the swing arm suspension Under the range (corresponding to the adjustment range of the pedal track), the length of the required shifting space of the front end of the side frame of the present invention is short, which is advantageous for mechanism arrangement, volume reduction, design, etc. ^3, if left and right The top surface of the second rod body is designed to be a part that can be grasped when the user goes up and down the pedal, and since the angle of the second rod body is not suitable due to the change of the pedal trajectory, the user can use ^ : and 201127445 Feel the part of the main body. Because the front end of the second rod is slidable back and forth on the support portion of the main frame body, the pressure on the driving device can be dispersed, for example, the aforementioned screw ( 74) The part screwed to the connecting component (24) does not have to bear the weight of the front end of the left and right side frames (20), so the driving action is relatively stable and smooth, and the related components are less likely to be worn and damaged.
