Description

Low Noise Electric Stepper The present invention relates to a low-noise electric stepper, and more specifically, to a low-noise electric stepper designed to allow a user to perform continuous stair-climbing exercises using an endless track method even in a narrow indoor space, and to provide a stable and quiet exercise environment through an electric drive and noise reduction structure. As sedentary lifestyles increase in modern society, the risk of various adult diseases such as obesity and diabetes is rising, highlighting the growing importance of aerobic exercise for prevention and maintaining health. Among various aerobic exercises, climbing stairs is known to burn more calories than walking on flat ground and offers excellent benefits for strengthening lower body muscles and improving cardiovascular endurance. However, since using actual building stairs is subject to limitations such as weather conditions, noise in public spaces, and safety hazards, there is a continuously increasing demand for exercise equipment that can simulate stair climbing indoors. Conventional home steppers primarily utilized hydraulic cylinders to move the steps up and down. While these hydraulic steppers are suitable for home use due to their small size, they have disadvantages such as difficulty in replicating continuous climbing motions similar to actual stairs, limited range of motion resulting in reduced exercise effectiveness, and the potential for users to easily become bored. On the other hand, large stair mills, which resemble escalators found in gyms, provide exercise effects nearly identical to actual stairs; however, they are bulky, generate significant operating noise, and are expensive, making them impractical for installation in ordinary homes. Furthermore, existing mobility devices and exercise equipment utilizing the caterpillar track system suffered from significant noise and vibration caused by friction between chains and gears during operation, limiting their use in multi-unit dwellings where inter-floor noise is a sensitive issue. Therefore, there is an urgent need to develop a new type of electric stepper suitable for indoor use that maintains a compact size suitable for home installation while enabling continuous stair climbing exercise by applying an endless track system, and especially by drastically reducing driving noise.
