Example 1
[0030] Reference Figure 1A multifunctional stair climber includes a frame 1, two rails 2, two footrests 3, and two handrails 4. The two rails 2 are arranged left and right and connected to the top of the frame 1. The frame 1 and the two rails 2 are arranged in an "eight" shape. Each footrest 3 corresponds to a rail 2 and is slidable up and down on the corresponding rail 2. Each handrail 4 corresponds to a footrest 3. The bottom of each handrail 4 is connected to the corresponding footrest 3. The two footrests 3 move up and down alternately.
[0031] Reference Figure 1 and Figure 2 The top rear end of the track 2 is provided with an inverted first U-shaped member 5, and two rollers 6 are arranged vertically inside the first U-shaped member 5. The handrail 4 passes between the two rollers 6. The two rollers 6 provide a limit for the movement direction of the handrail 4 and also make the handrail 4 smoother when moving up and down.
[0032] Reference Figure 1 and Figure 2 An inverted U-shaped pull rope 7 is connected between the two footrests 3. An inverted second U-shaped member 8 is provided between the tops of the two tracks 2. The second U-shaped member 8 houses at least two first rope pulleys 81 arranged left and right. The U-shaped pull rope 7 spans over the at least two first rope pulleys 81. In this embodiment, two first rope pulleys 81 are provided. A first connecting rod 9 is provided on one side of each footrest 3. A first rope rod 21 is provided at the bottom of one side of each track 2. A second rope pulley 91 is provided on one side of the first connecting rod 9. A first elastic rope 10 is provided between one side of the footrest 3 and the first rope rod 21. The first elastic rope 10 spans over the second rope pulley 91. The U-shaped pull rope 7 is used to achieve alternating up and down movement of the two footrests 3. The first elastic rope 10 provides resistance to the corresponding footrest 3 during its up and down movement.
[0033] Reference Figure 1 、 Figure 10 and Figure 13 The tops of the two rails 2 are hinged to the top of the frame 1, and the two handrails 4 are both provided with rotatable handrails 41. When in motion, the handrails 41 on the two handrails 4 are symmetrically oriented. Specifically, a tightening screw 42 is provided at the top of the handrail 4, and the handrail 41 is provided with a first screw hole 43, a second screw hole 44, and a plurality of second screw holes 45 arranged up and down. The first screw hole 43 and the third screw hole 45 arranged at the top are set at 80° or 100°, and the horizontal axis of the second screw hole 44 and the vertical axis of the third screw hole 45 are set at 90°. The first screw hole 43, the second screw hole 44 and the third screw hole 45 are distributed on different sides of the handrail 41. The cooperation of the tightening screw 42 and the plurality of second screw holes 44 can realize the height adjustment of the handrail 41.
[0034] Reference Figure 1 、 Figures 7 to 9 The footrest 3 includes a slide 31, a pedal mounting seat 32, and a pedal 33. The rear end of the pedal mounting seat 32 is hinged to the slide 31, and the pedal 33 is connected to the top surface of the pedal mounting seat 32. An upper rolling pulley 34 and a lower rolling pulley 35 are provided in the slide 31. The track 2 passes between the upper rolling pulley 34 and the lower rolling pulley 35. The upper rolling pulley 34 and the lower rolling pulley 35 provide a limit for the up and down movement of the footrest 3 on the track 2, while also making the up and down movement of the footrest 3 smoother. The slide 31 is provided with a third socket 36, and the pedal mounting seat 32 is provided with multiple groups of fourth sockets 37 arranged vertically. In this embodiment, the fourth sockets 37 are provided in four groups, and each group of fourth sockets 37 consists of two fourth sockets 37 arranged on the left and right. The third socket 36 and each group of fourth sockets 37 allow a rod 38 to pass through. When the angle of the pedal mounting base 32 needs to be adjusted, the insertion rod 38 is pulled out from the third hole 36 and the fourth hole 37. At this time, the rear end of the pedal mounting base 32 can be rotated to adjust the angle. When the pedal mounting base 32 is adjusted to the desired angle, the insertion rod 38 is inserted into the third hole 36 and the new fourth hole 37 to re-fix the pedal mounting base 32.
[0035] Reference Figure 1 、 Figure 2 、 Figures 7 to 11 The design principle of this utility model is as follows: When a user needs to exercise, they stand on the pedals 33 of the two footrests 3, hold the handrails 41 on the two handrails 4 with their hands, and then push the two footrests 3 with their feet to move their feet up and down alternately. At the same time, the two handrails 4 also move up and down alternately, thus achieving simultaneous linkage between the feet and hands, allowing the user to get a better whole-body exercise. Because a first elastic rope 10 is installed between each footrest 3 and the bottom of the corresponding track 2, both footrests 3 will feel significant resistance during the alternating up and down movement of the feet. When the stair machine is not in use, the frame 1 and the two rails 2 can be folded, the slides 31 and the pedal mounting seats 32 of the two footrests 3 can be folded, the tightening screws 42 on the two handrails 4 can be loosened, and the tightening screws 42 can be separated from the third screw holes 45. Then, the left handrail 41 can be rotated 100° counterclockwise and the right handrail 41 can be rotated 80° clockwise, and then the tightening screws 42 can be tightened on the first screw holes 43. Finally, the entire multifunctional stair machine can be folded, reducing the space occupied by the multifunctional stair machine. Example 2

The top end of the first elastic cord 10 is connected to a first insertion portion 11, which is inserted into the first insertion hole 92. In this embodiment, there are three first insertion holes 92. Each first insertion portion 11 can be inserted into different first insertion holes 92, thereby adjusting the resistance generated by the first elastic cord 10. Example 3

An inverted U-shaped elastic rope 15 is connected between the second rope rods 14 of the second connecting rods 12 on the two footrests 3, and the U-shaped elastic rope 15 spans the third rope pulley 13. In this embodiment, the resistance of the two footrests 3 is generated by a single U-shaped elastic rope 15. Example 4
[0038] Reference Figure 5 The specific implementation of this embodiment is basically the same as that of the third embodiment, except that: in the second connecting rods 12 on the two pedals 3, one side of one of the second connecting rods 12 is provided with a plurality of second insertion holes 16 arranged vertically. One end of the U-shaped elastic cord 16 is connected to a second insertion portion 17, which is inserted into the second insertion hole 16. The second insertion portion 17 can be inserted into different second insertion holes 16, thereby adjusting the resistance generated by the U-shaped elastic cord 15. Example 5
[0039] Reference Figure 6 The specific implementation of this embodiment is basically the same as that of the third or fourth embodiment, except that a third connecting rod 18 is connected between the upper portions of the two rails 2, and a first pulley 19 is provided on the third connecting rod 18. A fourth connecting rod 20 is connected between the lower portions of the two rails 2, and a second pulley 22 is provided on the fourth connecting rod 20. A belt 23 is provided between the first pulley 19 and the second pulley 22, and the belt 23 is connected to the two pedals 3. In this embodiment, the alternating up and down motion of the two pedals 3 is achieved by the belt 23 connected to the two pedals 3, and the belt 23 can reciprocate up and down around the first pulley 19 and the second pulley 22.
[0040] Reference Figure 12 and Figure 13In the five embodiments described above, when the screw 42 is tightened in the second screw hole 44, the left handrail 41 rotates 90° clockwise and the right handrail 41 rotates 90° counterclockwise. The multifunctional stair climber can then be used for tiger crawling exercises. Tiger crawling exercises can reduce the burden on the lumbar spine and knee joints, improve the cardiovascular system, promote blood circulation in the brain, and enhance physical fitness and coordination. A foam grip 46 can also be provided on the top of the handrail 41 for a person to hold onto during the tiger crawling exercise.
[0041] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
