The elderly or the patient is difficult to move from indoors to the toilet or dining table, so using crutches or walking aids. However, severely ill patients or elderly people who do not have the power to stand on their own are not only difficult to use walking aids alone, but even when using walking aids alone, it is difficult to maintain posture while moving, and there is a high risk of falling or getting hurt. Accordingly, a method of installing a guide rail on a ceiling and installing an auxiliary mechanism (for example, a seat belt worn by a user or a handle that a user can hold and move) on the guide rail moves along the guide rail has been developed.

However, when the guide rail is installed on the ceiling, the existing interior structure must be modified for the installation of the guide rail, which is expensive. In addition, since the guide rail and the ceiling must be coupled using a coupling member such as a screw along the guide rail, there is a concern that the ceiling may be damaged and the appearance may not be good. In addition, when the guide rail is installed on the ceiling, the user's load is applied to the guide rail, and as time passes, the combined portion of the guide rail and the ceiling may fall, damaging the ceiling, and even causing a serious injury to the user. have.

In addition, even when using an auxiliary device for moving the guide rail has a problem that it is difficult and uncomfortable for the elderly or patients who are uncomfortable to move alone to the toilet or kitchen. In particular, when there is an obstacle such as a threshold when moving indoors, there is a problem that it is difficult to move to the hall even when using the auxiliary mechanism.
