Description

Motion assist apparatus comprising a slider with balls The present invention relates to an exercise aid device comprising a slider in which a ball is received. With the recent intensification of the aging society, the number of people complaining of pain and discomfort due to joint problems is increasing, and interest in assistive devices that enable the elderly and patients with joint discomfort to walk smoothly is growing. The exercise assist device may include a proximal support for supporting a proximal part of a user, a distal support for supporting a distal part of a user, an actuator connected to the proximal support and generating power, a drive frame that transmits power to the distal support, a slider housing connected to the distal support and having a sliding space, and a slider configured to slide in the sliding space. Noise may occur as the slider comes into contact with the slider housing. When the motion aid is used repeatedly, the slider may be damaged or worn out due to friction between the slider and the slider housing. To mitigate this, there is a need for a new design for the slider structure to minimize the contact area between the slider and the slider housing.
