Description

Mobility aid and detachable rollator The present invention relates to a mobility assistance device and a detachable walker. The continuous increase in the elderly population necessitates the widespread adoption of age-friendly products, and this demand highlights the need for their development and evaluation from ergonomic and design perspectives. However, due to a lack of marketability, age-friendly products have not yet attracted the attention of many companies, resulting in a limited scope of product development and research. Consequently, this has led to a situation where the elderly are forced into inappropriate usage due to limited choices. Analysis of product safety accidents reveals that the accident rate among users aged 60 and older is significantly higher than that of users under 60. Specifically, the most common location was the home at 57.2%, followed by public administration and service areas at 14.7%, and roads at 9.8%. Regarding accident types, falls, slips, and falls accounted for 55.3%, followed by collisions and impacts at 7.5%, cuts or tears at 4.5%, and crushing or entrapment at 4.0%. In addition, by body part, the head and face accounted for 26.4%, the legs and feet 24%, the arms and hands 18.1%, and the neck, abdomen, back, and waist 14.7% (Status of Safety for the Elderly, Consumer Era, 4-5, October 2007). In particular, as can be seen from the types of accidents involving the elderly, fall-related accidents account for more than half. The most representative elderly-friendly product capable of preventing falls is the walker (roller). Recently, various products have emerged that incorporate diverse functionalities and enhance ease of use and durability. In this regard, continuous research and development is being conducted, including the roller-trolley equipped with a handle position adjustable according to use (Korean Published Patent Application No. 2017-0134394), the method and apparatus for estimating walking state for a walking aid (Korean Registered Patent Application No. 1908176), the Stroller rollator (U.S. Registered Patent Application No. 9974708), and the Foldable rollator (U.S. Registered Patent Application No. 9839571). Recently, the functions of walkers have been diversified; walkers that not only simply assist with user movement but also allow the user to sit, as described in Korean Registered Patent No. 10-2402692, have been introduced. In particular, electric walkers are being developed to assist users in driving, such as those described in Korean Registered Patent Publication No. 10-1673166, which enable the walker to move using its own power. However, since the motor for power supply is mounted directly on the walker, the weight of the walker increases, leading to a loss of its inherent advantages, such as lightness, ease of installation, and ease of storage.
