<p><P>PROBLEM TO BE SOLVED: To solve problems that since few chairs or wheel chairs, despite various kinds of their seat structure being proposed, are adjustable in their seat height, they require seat mats or cushions to place on the seats for their seat height adjustment, and that since no legless chairs are adjustble in the sitting height, they are hard to use for the elderly or the physically disabled. <P>SOLUTION: This sitting height adjustable chair, or this height adjustable bed is equipped with two or more jacks that are interconnected and aligned lengthways or sideways at established intervals, on which a platform base such as a seat base is mounted so that the height can be adjusted. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
