Patent Application
20250213426
The present invention relates to sports and massage equipment, and more particularly to a leg-and-foot device and a massage chair which are driven solely.
In recent years, as the pace of life continues to accelerate, sub-health problems have become increasingly prominent, and people's demand for massage to eliminate fatigue is also increasing. Manual massage is difficult to popularize into people's daily lives due to limitations in venue, cost and professionalism of personnel. Smart massage chairs are increasingly recognized by the public because they can use fragmented time, can be used at home and are low-cost.
Smart massage chairs usually include main trunk massage devices for the user's head, shoulders, back, buttocks, hands, legs and feet. In particular, because the legs and feet need to support the weight of the human body, they are prone to fatigue in people's daily lives. Therefore, the research on continuously improving massage devices for the legs and feet has become a main research direction for those skilled in the field.
At present, most leg and foot massage devices on the market use a relatively fixed method to massage the left and right legs and feet at the same time. However, in actual scenarios, many users have concerns about the stretching length, massage movements and massage of the left and right legs and feet. Each location has different requirements.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary aspect of the present invention is to provide a leg-and-foot device and a massage chair which is configured to stretch user's legs and feet based on customized using requirements.
