Thus, as shown in Figure 3 and Figure 9, when the second motor 61 drives the second screw 62 to rotate, the second screw 62 will first drive the second motor 61 to move up and down along the axial direction of the second screw 62, and then the second The second motor 61 will then drive the armrest frame 50 to pivot up and down relative to the lifting base 30 .

The pedal unit 70 has two opposite front sprockets 72 , two opposite rear sprockets 73 , two chains 74 , and a plurality of pedals 75 arranged front and rear. The two front sprockets 72 are assembled on the left and right sides of the front end of the lifting base 30 through a front axle 722; the two rear sprockets 73 are assembled on the left and right sides of the rear end of the lifting base 30 through a rear axle 732 Both sides; each chain 74 is wound around the front and rear sprockets 72,73 located on the same side, so that the front and rear sprockets 72,73 can rotate synchronously; each pedal 75 is pivotally connected to the two chains by a pedal shaft 752 74, so that each pedal 75 can be driven by the chain 74 to move circularly on the one hand, and on the other hand can pivot up and down relative to the lifting base 30. In addition, the pedal unit 70 also has a pedal adjustment frame 76 (as shown in FIG. 7 ), the pedal adjustment frame 76 has two opposite side plates 77, and the two side plates 77 are connected together by two support rods 78, each side The front end of plate 77 has an elongated hole 772 (as shown in Figure 2 ) that is pierced by front axle 722, and the aperture of elongated hole 772 is greater than the outer diameter of front axle 722, and the rear end of each side plate 77 has a Rectangular hole 774 (as shown in Figure 1) that rear wheel shaft 732 is perforated, the aperture of rectangular hole 774 is greater than the outer diameter of rear wheel shaft 732, can move up and down relative to lifting base 30 after side plate 77 is driven thus. In addition, as shown in Figure 7, the inner surface of each side plate 77 has a guide groove 776, and each pedal 75 is connected to each side plate 77 through a guide rod 754, and a guide wheel 756 is respectively installed on the two ends of the guide rod 754, and the guide The wheel 756 is rotatably embedded in the guide groove 776 of the side plate 77, so that not only can the stability of the pedal 75 be increased during cyclic operation, but also the pedal 75 and the pedal adjustment frame 76 can be operated synchronously.

As shown in FIGS. 4 to 8 , the pedal adjuster 80 has a third motor 81 , a third screw rod 82 , a third sleeve 79 , and a linkage seat 83 . The third motor 81 is installed on the lifting base 30, the front end of the third screw rod 82 is connected to the third motor 81, the third bushing 79 is screwed on the third screw rod 82 and the bottom end of the third bushing 79 is fixed on the linkage seat 83. Thus, when the third motor 81 drives the third screw 82 to rotate, the displacement of the third screw 82 through the third sleeve 79 will drive the linkage seat 83 to move forward and backward along the axial direction of the third screw 82 . In addition, the pedal adjuster 80 also has two relative connecting rod groups 84, as shown in Figure 4, Figure 6 and Figure 8, each connecting rod group 84 has a front slide rail 85, a rear slide rail 86, a front slide seat 87, a rear slide seat 88, a bracket 89, an upper slide rail 90, a lower slide rail 91, an upper slide seat 92, a slide seat 93, a first connecting rod 94, and a second connecting rod 95, The front slide rail 85 is fixed on the lifting base 30, the rear slide rail 86 is fixed on the lifting base 30 and relative to the front slide rail 85, the front and rear slide rails 87, 88 are respectively arranged on the front and rear slide rails 85, 86, and the support Frame 89 has a first support rod 892 and two mutually parallel second support rods 894, and the front and rear ends of the first support rod 892 are respectively connected to front and rear slide seats 87,88, and the two ends of the second support rod 894 Respectively connect the outer surface of the side plate 77 of the pedal adjustment frame 76 and the first support bar 892, and the upper slide rail 90 is fixed on the bottom surface of the first support bar 892 of the bracket 89 and is interposed between the front and rear slide rails 85, 86. ; The lower rail 91 is fixed on the lifting seat 30 and relative to the upper rail 90; the upper and lower seats 92, 93 are respectively located on the upper and lower rails 90, 91, and the lower seat 93 is connected to one end of the linkage seat 83 ( As shown in Figure 4), the sliding seat 93 can be driven by the linkage seat 83; the top and bottom ends of the first connecting rod 94 are respectively pivotally arranged on the first support rod 892 and the sliding seat 93 of the bracket 89, the second The top and bottom ends of the second connecting rod 95 are respectively pivoted on the upper sliding base 92 and the lifting base 30 , and the first and second connecting rods 94 , 95 are pivotally connected together in a manner of intersecting each other.

Through the above structure, if the user wants to change different climbing gradients, the first motor 41 can be started first, so that the first screw 42 can be driven by the first motor 41 to drive the lifting base 30 relative to the base. The seat 20 is deflected. At this time, the effect of adjusting the climbing slope can be achieved through the different angles presented after the deflection of the ascending seat 30. After the adjustment to an appropriate angle, the first motor 41 is turned off to keep the ascending seat 30 in position. When the time comes, the user can start to step on the pedal 75 for exercise training.

Since the lifting base 30 can change the angle relative to the base 20, in order to allow the user's hands to hold the armrest frame 50 in an ergonomic posture during the user's stepping on the pedal 75, the second motor can be further used. 61 drives the second screw rod 62 to drive the armrest frame 50 to deflect relative to the lifting base 30, and then close the second motor 61 until the armrest frame 50 is adjusted to an appropriate position. At this time, the armrest frame 50 can be positioned at a position suitable for the user to hold Location.

On the other hand, since the pedal 75 will be slightly inclined with the different lifting angles of the lifting base 30, in order to allow the pedal 75 to remain in a horizontal state for the user to step on as the angle of the lifting base 30 changes , the utility model can start the third motor 81 again, so that the third screw rod 82 is driven by the third motor 81 and drives the linkage seat 83 to push the sliding seat 93. After the sliding seat 93 is pushed, the first and second connecting seats are forced to Rods 94, 95 are relatively pivoted, and in the process of relative pivoting of first and second connecting rods 94, 95, bracket 89 will be pushed upwards. At this time, bracket 89 passes through front slide seat 87 and front slide rail 85 The cooperation of the rear sliding seat 88 and the rear slide rail 86 pushes the pedal adjustment frame 76 upwards, so that the pedal adjustment frame 76 moves upward relative to the lifting seat 30, and will be further used in the moving process of the pedal adjustment frame 76. The side plates 77 push the pedals 75 to pivot relative to the lifting base 30, so that the pedals 75 can still be kept in a horizontal state after the lifting base 30 changes the lifting angle, so that the user can step on it in a relatively labor-saving manner. In order to make the operation mode of the present utility model more efficient and convenient, the lifting seat adjuster 40, the armrest frame adjuster 60, and the pedal adjuster 80 can also be operated synchronously through electronic control, so that the lifting When the seat 30 changes the lifting angle, the pedal 75 or the armrest frame 50 can produce corresponding deflection to a position suitable for exercise.

To sum up, in addition to using the lifting base adjuster 40 to adjust the lifting angle of the lifting base 30, the stair machine 10 of the present invention also uses the pedal adjuster 80 to adjust the horizontal angle of the pedal 75, so that the user can Under the correct and comfortable posture, different climbing slopes can be trained. In addition, the armrest adjuster 60 can be used to adjust the lifting angle of the armrest frame 50, or the lifting seat adjuster 40, pedal adjuster 80 and The armrest frame adjuster 60 is synchronously linked, and the user can obtain a good supporting effect in operation, thereby achieving the purpose of the utility model.
