Abstract

An embodiment may provide a walking vehicle that supports a user's standing by including: a lower frame; a wheel unit installed on the lower frame; a vertical frame installed on the lower frame; a side frame installed on the lower frame and whose height is adjusted in correspondence with the height adjustment of the vertical frame; a handle frame installed on the side frame; and a chair installed on the handle frame; wherein, when a user transitions from a seated state on the chair to a standing state, the walking vehicle supports the user's standing by adjusting at least one of the height of the vertical frame, the height of the side frame, and the angle of the chair.

Claims (7)

  1. Lower frame; Wheel part installed on the lower frame above; A vertical frame installed on the lower frame above; A side frame installed on the lower frame and whose height is adjusted in correspondence with the height adjustment of the vertical frame; First and second handle frames installed on the above side frame; A shin support installed on the vertical frame above; It includes first and second chairs that are rotatably installed on each of the first handle frame and the second handle frame, and can be separated and rotated from each other. When the user transitions from a seated state to a standing state, the first chair and the second chair perform angle adjustment by increasing the height of the vertical frame and the side frame while simultaneously rotating the first chair and the second chair to push the user's buttocks forward, and at the same time, the shin support installed on the vertical frame supports the user's shin through angle and height adjustments, thereby limiting the range of change in the user's position in the front and rear, and thus supports the user's standing. After detecting height and rotation angle information of the vertical frame or the first and second handle frames measured in the user's sitting and standing states to estimate the distance between the user's knee height and the ground, angle adjustment and height adjustment of the shin support are performed. After standing is complete, the first chair and the second chair can be rotated to fold inward toward the first handle frame and the second handle frame, respectively, thereby securing rear space for the user during walking. A walker that supports the user's standing.

  7. In Article 1, A footrest installed on the lower frame and capable of placing the user's feet while the user is seated; further comprising A walker that supports the user's standing.

Description

A rollator that supports the user standing up The present invention relates to a walking vehicle that supports a user's standing. 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. As such, while development has so far focused on technologies for walkers to enhance walking stability for the elderly and those that support user seating, there is an increasing need for technology capable of supporting significant postural changes, such as when users transition from a seated to a standing position or vice versa, given that the primary users of walkers are the elderly and those with physical disabilities. FIG. 1 is a perspective view of a walking vehicle that supports a user's standing according to an embodiment of the present invention.
