Description

Technical Field

[0001] This utility model relates to a fitness equipment, and more particularly to a fitness equipment that simulates mountain climbing, stepping, and stair climbing exercises. Background Technology

[0002] To facilitate exercise without leaving home, various indoor fitness equipment has emerged on the market, among which the stepper is a frequently used one. The stepper allows users to repeatedly perform the motion of climbing stairs, enhancing cardiovascular function and effectively exercising the thigh and calf muscles. Its small size and space-saving design make it suitable for use anywhere in the home, making it a popular piece of fitness equipment. However, current steppers typically include a base frame, a left pedal, and a right pedal. A front support is located at the front of the base frame, allowing the front ends of the left and right pedals to rotate and connect to the front support frame. Hydraulic cylinders are installed between the left and right pedals and the base frame. This design results in the left and right pedals not always remaining parallel to the base frame during movement, and the stepping motion of the left and right pedals cannot create a consistent stride, failing to effectively simulate the movements of climbing mountains, stepping, and stair climbing, leading to a poor user experience. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a fitness equipment that simulates mountain climbing, stepping, and stair climbing. The left and right pedals remain parallel to the base frame when they are raised and lowered, and the left and right pedals form a certain step distance when they move back and forth. This can better simulate the movements of mountain climbing, stepping, and stair climbing, and improve the user experience.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a fitness equipment that imitates mountain climbing, stepping, and stair climbing exercises, including a base frame, a left connecting rod, a right connecting rod, a left pedal, a right pedal, a left hydraulic cylinder assembly, and a right hydraulic cylinder assembly; the left connecting rod and the right connecting rod each include two connecting rods that are obliquely parallel to each other on the left and right sides of the base frame and between the left and right pedals; the left hydraulic cylinder assembly and the right hydraulic cylinder assembly are obliquely connected to the left and right sides of the base frame and between the left and right pedals, and the connection directions of the left connecting rod and the right connecting rod are opposite to those of the left and right hydraulic cylinder assemblies, so that the left and right pedals always remain parallel to the base frame when they rise and fall, and form a certain step distance when the left and right pedals move back and forth.

[0005] The left and right connecting rods are arranged diagonally forward from top to bottom; the left and right hydraulic cylinder assemblies are arranged diagonally backward from top to bottom.

[0006] The left and right pedals and the base frame are respectively equipped with corner pieces. The two connecting rods of the left and right connecting rods are respectively pivotally connected in parallel between the corner pieces of the left and right pedals and the corner pieces of the base frame.

[0007] The pivot joints of the left and right pedals and one of the two connecting rods of the left and right connecting rods are also equipped with torsion springs to enable the left and right pedals and the left and right connecting rods to form a fully free motion.

[0008] The torsion spring is installed on the lower link of the left and right links, and the tensioning directions of the torsion springs of the left and right links are the same.

[0009] One end of the left and right cylinder assemblies is connected to the left and right sides of the base frame, respectively, and the other end of the left and right cylinder assemblies is connected to one of the two connecting rods of the left and right connecting rods, respectively. The connection positions are distributed at different heights so that the left and right cylinder assemblies can move back and forth relative to each other.

[0010] The pivot joint between the left cylinder assembly and the left connecting rod and / or the pivot joint between the right cylinder assembly and the right connecting rod are also equipped with knobs to facilitate disassembly.

[0011] The base frame is square-shaped.

[0012] A connecting pipe is also connected between the left and right cylinder assemblies to allow hydraulic oil to circulate between the two cylinder assemblies, thereby enabling the left and right pedals to move up and down in a staggered manner.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Because the left and right connecting rods each include two connecting rods that are obliquely parallel to each other on the left and right sides of the base frame and between the left and right pedals; the left and right hydraulic cylinder assemblies are obliquely connected to the left and right sides of the base frame and between the left and right pedals, and the connection directions of the left and right connecting rods are opposite to those of the left and right hydraulic cylinder assemblies, the left and right pedals always remain parallel to the base frame when they are raised and lowered, and the left and right pedals form a certain step distance when they move back and forth, which can better simulate the actions of climbing mountains, stepping, and climbing stairs, thus improving the user experience.

[0015] 2. Because the corner pieces of the left and right pedals and at least one of the two connecting rods of the left and right connecting rods are also equipped with torsion springs, the left and right pedals and the left and right connecting rods can form a full degree of freedom of movement, which improves the user experience.

[0016] 3. Because the pivot joint between the left cylinder assembly and the left connecting rod and / or the pivot joint between the right cylinder assembly and the right connecting rod are also equipped with knobs, the device can be easily disassembled.

[0031] In this embodiment, as Figure 6 , Figure 7 As shown, a torsion spring 8 is also installed at the pivot point of the corner piece 41 of the left pedal 4 and the two connecting rods of the left connecting rod 2. The torsion spring 8 is installed at the lower connecting rod of the two connecting rods of the left connecting rod 2. Specifically, torsion springs 8 are installed at the corner pieces of the left pedal and the right pedal and at the pivot points of the left and right connecting rods, and the tension directions of the torsion springs of the left and right connecting rods are the same. The torsion springs are respectively installed at the lower connecting rods of the two connecting rods of the left and right connecting rods, so that the left pedal 4, right pedal 5 and left connecting rod 2, right connecting rod 3 can form a full degree of freedom of movement.

[0032] In this embodiment, one end of the left cylinder assembly 6 and the right cylinder assembly 7 are respectively connected to the left and right sides of the base frame 1, and the base frame 1 is provided with U-shaped parts 13 and 14 for connecting the left cylinder assembly 6 and the right cylinder assembly 7.
