Chair with Mechanism to Assist Standing Up and Sitting Down for Elderly or Disabled Persons

摘要

The present invention provides a self-assist chair (100) comprising; a chair frame portion (110), a moveable and tiltable seat portion (150) spaced apart from the horizontal back portion (160), a track (120, 130) and roller (180, 190) system allowing movement of the seat portion (150) of the chair, a spring (200) mechanism connecting the seat portion (150) of said chair (100) and a horizontally moveable part of said chair frame (110) portion. The spring (200) mechanism of the self-assist chair (100) includes a track guided release mechanism responsive to forward movement such that movement of the rollers (180, 190) on the tracks (120, 130) to a preset position releases the spring (200), thereby urging and tilting the seat portion (150) upwards facilitating the exit of a user from a chair (100). Conversely a compressing mechanism is responsive to backward movement of the rollers (180, 190) on the tracks (120, 130) to a preset position compresses the spring (200), urging and flattening the seat portion (150) to a horizontal plane facilitating the entry of a user into a chair (100).
