The specific embodiment will be described below with reference to the accompanying drawings - as shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, the stepper chassis 1 of the armrest is a tubular metal welded component. The damper assembly 2 is mounted by bearings at the rear of the chassis 1, the armrest shaft assembly 3 is mounted by bearings in the middle of the chassis 1, and the left pedal lever 4 and the right pedal lever 5 are mounted by bearings at the head of the chassis 1. Long chain 61 and damper in damper chain assembly 6 The large sprocket 21 on the assembly 2 is matedly coupled, and the left and right pedal levers 5 are connected at both ends of the damper chain assembly 6, respectively. The short chain 71 in the armrest chain assembly 配合 is coupled to the small sprocket 31 in the armrest shaft assembly 3, and both ends of the armrest chain assembly 7 are connected to the left pedal lever 4 and the right pedal lever 5, respectively. The armrest 8 is connected to the armrest shaft assembly 3, and the left pedal 9 and the right pedal 10 are connected to the left pedal lever 4 and the right pedal lever 5, respectively.

The left pedal lever 4 and the right pedal lever 5 are coupled to the base 1 by bearings, and can convert the up and down movement of the pedal into a member of the three-dimensional lever in which the long chain 61 and the short chain 71 reciprocate. The armrest shaft assembly 3 includes a small sprocket 31, a small tubular member 32 and a large tubular member 33, and the small sprocket 31 is fixedly coupled to the small tubular member 32, and the small tubular member 32 and the large tubular member 33 are fixedly coupled. The damper assembly 2 includes a large sprocket 21, a damper 22, a threaded shaft 23, a washer 24, a spring washer 25, a large nut 26 and an adjusting screw 27, a damper 11 and a threaded shaft 23 fixedly connected, a large chain The wheel 21 is connected by a key and a threaded rotating shaft 23, and the washer 24, the spring washer 25 and the large nut 26 are connected to the threaded rotating shaft 23, and a screw hole 28 is arranged on one surface of the large nut 26, and the adjusting screw 27 and the screw hole 28 are matched. connection. Both the damper chain assembly 6 and the armrest chain assembly 7 are provided with thread adjustment means 62 for adjusting the overall length of the chain and for easy installation. The chassis 1 is provided with a positioning post 11 that limits the rotational extent of the left pedal lever 4 and the right pedal lever 5. The armrest 8 is an ergonomically designed tubular member of adjustable front-rear distance and upper and lower lengths. The specific shape is an L-shaped side, and the handle position is a slightly curved in-line tubular member. A step counter is provided at the front end of the left pedal 9. The damper 22 in the damper assembly 2 is a rotary friction type damper. The damper assembly 2 is also provided with a detachment prevention cover for preventing the long chain 61 from coming off the large sprocket 21, which is fixed to the frame and is a ring-shaped housing member.

As shown in FIG. 7, the thread adjusting device 62 includes a chain connecting block 621, and a connecting screw 622. The connecting nut 624 is connected to the nut 625, wherein one end of the connecting screw 622 is provided with a thread, and one end is provided with a hole for cooperating with the chain connecting block 621, and a hexagonal nut column 623 for connecting the screw is disposed at a portion thereof, and the connecting portion is provided. The nut 624 is provided with a screw hole for engaging with the connecting screw 622, and the other end of the connecting nut 624 is provided with a pull structure for connecting with the hole on the pedal lever. As can be seen from the design, by twisting the hex nut post 623 in the middle of the connecting screw 622, the length of the chain can be tightened, so that the length of the chain can be adjusted.

When using, people stand on the left and right pedals, and the hands are held by the handrails. If the position of the handrails is not suitable, you can adjust the position to the appropriate comfortable position by adjusting the screws on the handrails. After the station is finished, the user steps on the left pedal down. During the movement, the left pedal lever rotates around the fulcrum above the base, by tightening the long chain on the damper assembly thereon, rotating the damper and driving the upward movement of the right pedal lever, and the damper can generate a certain resistance to hinder the damping. The rotation of the device itself hinders the downward movement of the pedal, and according to this design, the effect of the user's mountain climbing is simulated. When the left pedal lever rotates around the fulcrum on the base, it also rotates the armrest shaft by tightening the short chain on the armrest chain assembly on it, thus causing the armrest to swing, so that it can be attached at the same time as the step The twisting action trains the user's hand and foot coordination. After the left pedal lever rotates to a certain extent, it will touch the positioning post set on the chassis. At this time, the user needs to step on the right pedal, so that the right pedal lever rotates around the pivot point on the base, so that it will return and form. The up and down movement of the pedal, the rotation of the damper, and the swing of the armrest. Set a step counter on the right pedal to see the amount of movement of the user, the step frequency of the step, and other parameters. The damper assembly is provided with an adjusting screw, which can adjust the resistance of the damper, and can easily adjust the strength of the stepper movement.
