At this time, the second section 512 of the running platform 50 is The supporting wheel frame 55 is placed on the supporting surface 5 F, and the first section 511 can be combined with the base unit 30 by the folding device 6Q; further, by the two first pivot members 76 pivotally connects the pivotal joint portion 712 of the second guide rod 71 of the guide unit 70, and the support portion 711 of the second guide rod 71 is provided with the two rollers 73 and is located in the groove of the two side rods 31 of the base unit 30 The two connecting rods 81 are pivotally connected in the chamber 34 between the two guide rods 71 and the two side 10 rods 31 through two second and third pivot members 83 and 84, and the two side rods 31 and The support unit 90 is installed between the two side frames 51. In this way, when a user runs on the running belt 54, the overall weight is composed of the pieces 76, 83, 84 and the two rollers 73 and the The support unit 90 bears evenly, so it can effectively reduce the 15 damage rate of these pieces 76, 83, 84, and can relatively effectively maintain the smooth running of the running platform 50. As shown in Figs. 7 and 8 and Figs. 4 and 6, in order to collapse the running platform 50, an upward force is applied to the second section 512 of the running platform 50, so that the running platform 5G can use the second -The pivot member 76 is a support shaft that rotates and produces a close action toward the handle single το 40. At this time, the two guide rods η 20 of the guide unit 70 will swing, and the two rollers 73 will be in the two slot chamber. 34 and from that end. P 311 slides toward the second end portion 3 i 2, so the two guide rods 71 actually swing and move. The movement can be used to operate the running platform 50 lightly. When the running platform 50 is rotated to The end of the trip indicates that the collapsed position has been reached and the treadmill 3 is in a collapsed state; in addition, by installing the cut order between 10 1221779 the: seat unit 30 and the treadmill 5G, there are eight The running platform 50 can be prevented from falling down when being touched by an external force, thereby preventing an effect outside the sound. As shown in 5, 9, and 10, to increase the oblique delivery time of the running platform 50, the lift order is started to rotate with 00 motor ⑽, and the driver drives 105 to extend and drive the second guide. The shift lever 71 generates a swing, and the two rollers 73 will slide in the two tank chamber 34 from the first end portion toward the second end portion 312 'relatively raising the first 10 segments of the running platform 50 The distance between 511 and the swinging surface F achieves the effect of raising the running tower. 15 Conversely, as shown in FIGS. 10, 9, and 7, when the slope of the running building 50 is lowered, the driving horse of the lifting unit 100 is rotated in the reverse direction, and the driving rod can be driven. Retract and drive the two guide rods 7m to swing, at the same time, the two rollers 73 will slide in the two groove chamber 34 and from the second end portion 312 toward the first end portion 311, thereby relatively reducing the running platform. The distance between the 50 ° first section 511 and the support surface F has the effect of reducing the running platform 50. To sum up, the folding device of the treadmill of the present invention has the use effect and advantages as described above, so it can achieve the purpose of the invention: 20 First, because the folding device 60 of the present invention is installed on the running platform 5 ( ) Between the first section 511 and the base unit 30, plus the folding device 60 includes the guide unit 70, the connecting unit 80 and the support unit 90, so when the running platform 50 is located at the receiving unit When in the closed position, the treadmill 3 can still have excellent stability and benefits. 11 1221779 2. Because the second guide rod 71 of the guide unit 70 of the present invention has a swingable and movable design, whether it is to fold the running platform to a folded position or unfolded to a use position, it has a Efficacy and advantages of operating the running platform 50 lightly. 5 2. Because the total weight of the user and the running platform 50 in the use state of the present invention can be determined by the first pivot member 76, the second pivot member 83 and the second engaging member 84 of the folding device 60, and the The support unit 90 bears on average, which can relatively effectively reduce the deformation and damage rate of the pivot members 76, 83, 84, and has the effect and advantage of maintaining the smooth running of the running platform 50. 10 However, the above is only a preferred embodiment of the present invention. When the scope of implementation of the present invention cannot be limited in this way, that is, the simple equivalent changes made according to the scope of the patent application and the content of the invention specification of the present invention and Modifications should still fall within the scope of the patent of the present invention.
