Dependent claims

A safe multi-functional foldable leisure chair comprising a chair frame body, a chair pad disposed on said chair frame body, and a water-guiding pad optionally detachably disposed on said chair frame body, wherein said chair frame body is composed of:

a U-shaped front support leg and a U-shaped rear support leg, said front and rear support legs respectively having upper open sides and lower close sides, said upper open sides being connected with each other while said lower close sides being extended forward and rearward in a stretched state;
a horizontally disposed U-shaped seat frame having an open side which faces rearward, a plurality of first beam members being disposed between two arms of said seat frame, and a second beam member being disposed across said open side of said seat frame, two ends of said second beam member laterally projecting from said open side of said seat frame;
an H-shaped back frame having two lateral column members upper ends of which being slightly bent rearward and lower ends thereof being connected with said open side of said seat frame by angle-adjusting means so that the angle contained by said back frame and said seat frame can be freely adjusted;
two rail members disposed on said connected open sides of said front and rear support legs;
two pivot seats pivotally connected with front ends of said rail members and said open sides of said front and rear support legs, permitting said rail members and said front and rear support legs to be pivoted toward one another through a certain angle;
two fixing sets each of which has a T-shaped fixing rod and a fixing plate, wherein said fixing plate is secured on an inner middle section of said rear support leg and formed with an L-shaped slot having a downward facing hook portion, lower end of said T-shaped fixing rod extending downward to connect with the end of said second beam member which goes through said L-shaped slot , upper end of said fixing rod being pivotally connected under a rear end of said rail member, whereby when the end of said second beam member is engaged in said hook portion of said L-shaped slot, said chair frame body is prevented from being folded while when the end of said second beam member is slided within said L-shaped slot, said chair frame body can be folded into a small body;
and
two front stopper blocks and two rear stopper blocks, wherein said front stopper blocks are disposed on a middle section of said front support leg and said rear stopper blocks are disposed between said fixing means and said rear support legs, whereby when said front and rear support legs are pivoted toward each other, said front and rear stopper blocks prevent the hands of the user that hold said front and rear support legs from being clamped and injured;
and wherein
said chair pad is formed by a large cushion and a small cushion connected therewith, a plurality of loop-hook fasteners being disposed along a periphery of said chair pad, whereby the chair pad can be detachably fastened over said chair frame body by means of securing said fasteners with said seat frame and back frame;
and wherein
said water-guiding pad is provided with two U-shaped clamping members disposed on a bottom surface of said water-guiding pad, whereby after said small cushion is detached from said back frame , said clamping members can be secured on said column members of said back frame to fix said water-guiding pad on said back frame, forming a shampooing chair.
