[0002] A stepper is a fitness machine that simulates climbing stairs or walking. By providing resistance, it helps users exercise lower limb muscles and improve cardiovascular function. Due to its simple and lightweight structure and good exercise effect, the stepper is a popular home fitness equipment. By stepping on the pedals, users can improve their cardiovascular function as an aerobic exercise and fully exercise their lower limb muscles. However, existing steppers only target lower limb training and cannot exercise the upper limbs at the same time, thus failing to achieve a full-body workout effect and having certain limitations in exercise effectiveness. Summary of the Invention

[0003] This invention addresses the problem that existing steppers cannot exercise the upper limbs, and provides a stepper machine accordingly. The objective of this invention is achieved through the following technical solution:

[0004] A stepper includes a base and two sets of foot pedals mounted on the base. The base is also equipped with two handrails, each of which is connected to the base via a connector. The connector supports the handrail in an initial upright position, and when an external force is applied to the handrail, the connector allows the handrail to deviate from the upright position in multiple directions.

[0005] Preferably, the base is fixed with two symmetrical connecting rods, and the two handrails are respectively connected to the connecting rods on the same side through connectors; the connectors are elastic members, and when the handrails swing, the connectors provide swing resistance to the handrails; after the external force disappears, the connectors provide restoring force to the handrails.

[0006] Preferably, the connecting member is a helical spring, and the handrail is coaxially arranged with the corresponding helical spring and connecting rod. The handrail can perform a planar pendulum in its plane or a conical pendulum around the central axis of the corresponding connecting rod.

[0007] Preferably, the helical spring is segmented, comprising a first connecting segment, a deformation segment, and a second connecting segment from top to bottom. The first connecting segment is connected to the lower end of the handrail, and the second connecting segment is connected to the upper end of the connecting rod.

[0008] Preferably, the first connecting section and the second connecting section are cylindrical with equal diameters, the first connecting section is tightly fitted to the lower end of the handrail, and the second connecting section is tightly fitted to the upper end of the connecting rod; the deformable section is spindle-shaped.

[0009] Preferably, the base includes a front support and a rear support that are supported on the ground. The front support has two sleeves formed on it, and the two connecting rods are respectively inserted and fixed in the sleeves on the same side. A vertical beam is provided on the front support, and the vertical beam is located between the two sleeves. A diagonal brace connects the vertical beam and the rear support.

[0010] Preferably, the foot pedal assembly is located on both sides of the diagonal brace. Each foot pedal assembly includes a foot frame mounted on the outside of the upright beam and a foot pedal fixed above the foot frame. A damping rod is provided between each foot frame and the front support.

[0011] Preferably, the bottom of the diagonal brace is rotatably fitted with a pulley, and a steel rope is wound on the pulley. The two ends of the steel rope are respectively fixed to two foot pedals.

[0012] Compared with existing technologies, this utility model has the following technical advantages: The added handrail supports planar pendulum and conical pendulum motions, simulating the trajectories of movements such as boxing, skiing, and abduction, increasing training diversity, and achieving upper limb training while conducting lower limb training, thus improving training effectiveness; the use of helical springs to connect the handrails provides necessary support force and generates elastic deformation to adapt to the multi-angle swing of the handrails, while also providing swing resistance and restoring force; the helical springs are segmented, with two connecting segments for easy connection, and the spindle-shaped deformation segment provides nonlinear resistance, with resistance increasing as the swing amplitude increases, balancing safety and training intensity; the steel rope pulley linkage system achieves dynamic balance between the left and right pedals, enhancing coordination training.

Detailed Implementation

[0018] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0019] See Figures 1-4This embodiment discloses a stepper, which includes a base and two sets of foot pedal assemblies mounted on the base. Two handrails 10 are also mounted on the base, each handrail 10 being connected to the base via a connector. The connector supports the handrail 10 in an initial upright position. When an external force is applied to the handrail 10, the connector allows the handrail 10 to deviate from the upright position in multiple directions. The added handrails 10 support multi-directional deflection within a range of 0-60°, simulating movement trajectories such as boxing, skiing, and abduction, increasing training diversity, and enabling upper limb training while simultaneously training the lower limbs, thus improving training effectiveness.

[0020] Two symmetrical connecting rods 31 are fixed on the base, and the two handrails 10 are respectively connected to the connecting rods 31 on the same side through connectors. The connectors are elastic members. When the handrails 10 swing, the connectors provide swing resistance to the handrails 10. After the external force disappears, the connectors provide restoring force to the handrails 10. In practical applications, specifically, in this embodiment, the connector is a helical spring 20. The handrails 10, the corresponding helical springs 20, and the connecting rods 31 are coaxially arranged. The handrails 10 can perform planar pendulum swings in their respective planes or conical pendulum swings around the central axis of the corresponding connecting rods 31. By using the helical springs 20 to connect the handrails 10, the necessary support force can be provided for the handrails 10, and elastic deformation can be generated to adapt to the multi-angle swing of the handrails 10, while also providing swing resistance and restoring force.

[0021] The helical spring 20 is segmented, comprising a first connecting segment 21, a deformation segment 23, and a second connecting segment 22 from top to bottom. The first connecting segment 21 is connected to the lower end of the handrail 10, and the second connecting segment 22 is connected to the upper end of the connecting rod 31. Both the first connecting segment 21 and the second connecting segment 22 are cylindrical with equal diameters. The first connecting segment 21 is tightly fitted to the lower end of the handrail 10, and the second connecting segment 22 is tightly fitted to the upper end of the connecting rod 31. The deformation segment 23 is spindle-shaped. The segmented design of the helical spring 20 facilitates connection between the two connecting segments, and the spindle-shaped deformation segment 23 provides non-linear resistance, with resistance increasing as the swing amplitude increases, balancing safety and exercise intensity.

[0022] The base includes a front support 32 and a rear support 33 supported on the ground. Two sleeves 36 are formed on the front support 32, and two connecting rods 31 are respectively inserted and fixed in the sleeves 36 on the same side. A vertical beam 34 is provided on the front support 32. The vertical beam 34 is located between the two sleeves 36. A diagonal brace 35 is connected between the vertical beam 34 and the rear support 33. The diagonal brace 35-vertical beam 34 triangular support structure and the rear support 33 form a stable mechanical triangle to counteract the lateral torque generated by the swing.

[0023] The foot pedal components are located on both sides of the diagonal brace 35. Each foot pedal component includes a foot frame 41 mounted on the outside of the upright beam 34 and a foot pedal 42 fixed above the foot frame 41. Each foot frame 41 is provided with a damping rod 43 between it and the front support 32 to provide pedaling resistance. The bottom of the diagonal brace 35 is rotatably equipped with a pulley 51, and a steel rope 52 is wound around the pulley 51. The two ends of the steel rope 52 are fixed to the two foot frames 41 respectively. The linkage system of steel rope 52 and pulley 51 realizes the dynamic balance of the left and right pedals and enhances coordination training.
