Description

Technical Field

[0001] The utility model relates to the technical field of sports equipment, in particular to an elliptical machine with adjustable height. Background Art

[0002] The elliptical machine is a piece of indoor fitness equipment designed to simulate the motion of cross-country skiing, providing a low-impact aerobic experience. Key features of the elliptical machine include its elliptical motion path, which mimics the natural motion of human movement, allowing users to experience the feeling of outdoor exercise while indoors. The continuous, circular stepping motion of this machine effectively increases heart rate, promotes blood circulation, and enhances cardiopulmonary function. Using an elliptical machine not only improves cardiopulmonary endurance and builds muscle strength, but also aids in fat burning and weight management. Furthermore, it promotes overall muscle coordination, including lower and upper limb movement. With continued exercise, it strengthens leg muscles, enhances hip definition, and strengthens upper limb muscles through forward gripping, pushing, and pulling movements. The elliptical machine is suitable as part of a daily exercise routine to improve body shape and, with a proper diet, can help reduce body fat, manage weight, and sculpt your body.

[0003] After searching, the Chinese utility model patent disclosed with publication number CN214971530U discloses an elliptical machine, which includes a support frame and a counting mechanism; the front end of the support frame is connected to the counting mechanism, and the counting mechanism includes a lap counting disk, a pair of telescopic rods and a pair of threaded tracks; the pair of threaded connections are respectively fixedly connected to the two sides of the lap counting disk, and one end of the telescopic rod is slidably connected to the threaded track; the other end of the pair of telescopic rods is rotatably connected to a turntable, and the pair of turntables are symmetrically arranged; a rotating rod is fixedly connected to the inner side of the middle of the lap counting disk, and the two ends of the rotating rod are rotatably connected to the pair of turntables; the other side of the pair of turntables is connected to a motion mechanism, and the pair of motion mechanisms are symmetrically arranged. By sliding the telescopic rod on the lap counting disk, the telescopic rod is rotated to pass the sensor, and a prompt sound is issued. At this time, people change the direction of movement and complete periodic regular movement, which is more in line with scientific planned exercise and can enable people to achieve better exercise effects.

[0004] However, the device lacks a height adjustment function, and the height of the handle cannot be adjusted according to the user's height when in use, resulting in a lower range of applicability. Not only that, the device also lacks an angle adjustment function, and the user cannot adjust the angle of the elliptical machine when in use to simulate different scenarios, resulting in a situation where the needs of the user cannot be met.
