The resistance device 13 has an axis (not shown in the figure) and provides operation resistance. The two transmission components 15 are respectively connected to a foot tube 12, and the resistance device 13 is connected through the ratio changing device 14. In this embodiment, each transmission component 15 may include, but is not limited to, an elastic device 150, a timing belt 152, and a timing gear 154. Among them, the elastic device 150 is preferably a spring, with a first end connected to the frame 10 (for example, connected to the main frame 102 of the frame 10), a second end connected to the first end of the timing belt 152, and the first end of the timing belt 152 A foot tube 12 is connected to the two ends, for example, a part of the foot tube 12 between the first end and the second end is connected. In addition, a part of the timing belt 152 meshes with the timing gear 154. In addition, the timing belt 152 can bypass one or more pulleys. For example, the timing belt 152 bypasses the first pulley 156 provided on the base 101, and then bypasses the timing gear 154 and connects to a foot tube 12.
[0056] reference Figure 2 to Figure 5 , The two sliding pipes 18 are respectively located on both sides of the frame 10 and connected with the frame 10 respectively. For example, the first end of each sliding tube 18 is connected to the main frame 102, and the second end of each sliding tube is connected to the base 101. In addition, in this preferred embodiment, the exercise device 1 further includes two roller sets 17, each roller set 17 includes a front wheel 172 and a rear wheel 174, wherein the central axis of the front wheel 172 and the central axis of the rear wheel 174 Connect a foot tube 12. The front wheel 172 and the rear wheel 174 can be respectively located at the front and rear of a sliding tube 18, and the rear wheel 174 has a groove in the shape of the sliding tube 18, so that the rear wheel 174 abuts against the sliding tube 18, and the front wheel 172 does not contact the sliding tube 18, but the movement of the foot tube 16 can be restricted to move along the sliding tube 16. Each roller set 17 may also include a fixing mechanism (not shown in the figure) to fix the front wheel 172 and the rear wheel 174. The size of the rear wheel 174 may be larger than the front wheel 172. With the above structure, the pedal 16 is restricted from moving between the upper end and the lower end of the sliding tube 18 along the arc profile. Figure 4 The display roller set 17 drives the pedal 16 to make an arc-shaped movement track P. Such as Figure 4 As shown, when the pedal 16 moves to a high point, its angle is relatively inclined; Figure 5 As shown, when the pedal 16 moves to a low point, its angle is slightly forward or close to horizontal, which conforms to the ergonomics of stepping, stepping, or mountaineering, so that the operator will not feel discomfort. According to the roller set 17 of the preferred embodiment of the present invention, the stability of the pedal 16 during movement can be improved. When the speed of the pedal 16 increases, the sliding tube 18 will not be separated.
[0057] reference Figure 2 to Figure 5 In this preferred embodiment, the two transmission components 15 are connected to the resistance device 13 through a ratio changing device 14. In this preferred embodiment, the resistance device 13 is used to provide resistance, and may include, but is not limited to, a belt pulley 132 and a flywheel 134, which may be connected by a connecting member (such as a belt). The variable ratio device 14 may include, but is not limited to, a large wheel 140 and a small wheel 142. The large wheel 140 may be arranged on the main frame 102. The large wheel 140 and the small wheel 142 are connected by a transmission member (such as a belt). The resistance device 13 is connected by a bearing (not shown in the figure), and the two timing gears 154 are axially connected with the big wheel 140 by a one-way bearing (not shown in the figure). Thus, when the user stands on the pedal 16 and applies force to move the pedal 16 down along the sliding tube 18, the timing belt 152 drives the timing gear 154 to rotate, the timing gear 154 drives the big wheel 140 to rotate, and the big wheel 140 The small wheel 142 and the pulley 132 are driven to rotate, and the pulley 132 drives the flywheel 134 to rotate. When the user does not apply force, the elastic device 150 can pull the pedal 16 upward through the timing belt 152 so that the pedal 16 moves upward along the sliding tube 18. At this time, the timing gear 154 will not drive the big wheel 140 to rotate.
[0058] In this preferred embodiment, the timing gears 154 of the two transmission assemblies 15 are connected to the resistance device 13 through a ratio changing device 14. In other embodiments of the present invention, the timing gears 154 of the two transmission components 15 can also be directly connected to the pulley 132 of the resistance device 132 through a one-way bearing (not shown in the figure). That is, the variable ratio device 14 can be omitted.
[0059] Since the resistance device 13 has a transmission assembly 15 on each side, and a foot tube 12 is connected respectively. Therefore, unlike the prior art that connects the resistance device 13 through two cranks, the two pedals 16 can be operated independently. That is, the two pedals 16 can be simultaneously forced to move down along the corresponding sliding tube 18, or simultaneously pulled up by the corresponding transmission assembly 15 and moved up along the corresponding sliding tube 18 at the same time. Alternatively, the two pedals 16 can perform relative movement up and down.
