Abstract

A telescoping foldable chair having a skeleton having a pair of lower leg frames of U shape each having a pair of outer legs connected with a ground bar, a pair of upper leg frames of inverted U shape each having a pair of inner legs connected with a top cross bar respectively slidable contained in one of the outer legs, a front and a rear sets each having a pair of inner tubes respectively pivotally linked to the top cross bars, a pair of outer tubes respectively pivotally linked to one lower end of the outer leg frames, and a central link which pivotally connects free ends of the inner and outer tubes, and, a sitting cloth attached on the skeleton. The telescoping foldable chair has a strong structure yet small folded volume.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to a telescoping foldable chair, and more particularly, to a foldable chair which has a strong structure and small folded volume.[0003]2. Description of the Prior Art[0004]Shown in FIGS. 4 and 5 is a conventional foldable chair 9. The foldable chair 9 has a skeleton 91, a sitting cloth 92 attached thereto, and a back cloth 93 attached thereto. The foldable chair 9 has a plurality of linking poles 94 which is used to make the non-telescoping bars of the skeleton 91 foldable with respect to each other. This foldable chair 9 has some drawbacks: a volume of the foldable chair is large and a operation of folding and expanding may be dangerous since the linking poles 94 may nip fingers of a user. A smaller folded volume of foldable chair is favorite. But a smaller volume usually means less structure tubes of chair skeleton. Therefore, a foldable chair having relatively more constructive skeleton tubes th...
