A foldable chair comprising:
- a pair of front right and left supporting legs disposed to be spaced apart from each other in a longitudinal direction, each of said front right and left supporting legs having a top portion, a bottom portion, and an intermediate portion interposed therebetween;
- a pair of rear right and left supporting legs disposed to be spaced apart from each other in the longitudinal direction, each of said rear right and left supporting legs having a top portion, a bottom portion, and an intermediate portion interposed therebetween, said rear right and left supporting legs being respectively spaced from said front right and left supporting legs in a first transverse direction relative to the longitudinal direction;
- four stretchers, each disposed to brace two adjacent ones of said front right and left supporting legs and said rear right and left supporting legs in either one of the longitudinal direction and the first transverse direction, each stretcher including
- a pair of lower anchoring ends secured relative to two corresponding ones of said bottom portions of said two adjacent ones of said supporting legs, respectively, and
- a pair of upper hook ends retainingly slidable relative to two corresponding ones of said intermediate portions of said two adjacent ones of said supporting legs, respectively, wherein each of said upper hook ends is movable slidably between a folded position where a corresponding one of said upper hook ends is proximate to a respective one of said top portions, and where said two respective adjacent supporting legs are closer to each other, and a spread position where said corresponding one of said upper hook ends is distal to said respective one of said top portions;
- a front pair of first coupling members and a rear pair of first coupling members, each having a tubular member sleeved slidably on a respective one of said intermediate portions, and connected to a respective one of said upper hook ends such that each of said first coupling members will come to a stop and will be retained with a corresponding one of said intermediate portions when said supporting legs are placed in said spread position, a length of each of said front pair of said tubular members in the second transverse direction being of a dimension such that when said supporting legs are in said folded position, a corresponding one of said top portions of said front right and left supporting legs is confined by and is disposed inwardly of said tubular member;
- a front pair of second coupling members and a rear pair of second coupling members, each slidably mounted on said corresponding one of said intermediate portions, and disposed above and engageable with a respective one of said first coupling members in a second transverse direction that is transverse to both the first transverse direction and the longitudinal direction, each of said second coupling members including a gripping portion;
- a flexible seat sheet disposed to be grasped by said gripping portions such that when said supporting legs are in said spread position, said flexible seat sheet is tensed in both the longitudinal and first transverse directions;
- and
- a pair of armrests, each including a lug end mounted slidably on a respective one of said top portions of said rear right and left supporting legs, and an armrest body having a proximate portion movable pivotally relative to said lug end, and a distal portion capping a corresponding one of said top portions of said front right and left supporting legs.
