Combinative Toilet Chair

Abstract

A combinative toilet chair includes left and right armrest frames, a seat frame provided between the armrest frames and configured to support a vessel, and a backrest frame provided behind the armrest frames. The seat frame and the backrest frame have connecting ends provided with retractable pins and engageably insertable into insertion portions of the armrest frames. The insertion portions at rear sides of the armrest frames are threadedly provided with fasteners for pressing against and thereby securing the seat frame. Each armrest frame has lower ends connected with telescoping legs linked to the armrest frame by elastic bands. The legs can be secured to the armrest frames or detached therefrom so as to fold against the armrest frames. When assembled, the toilet chair is stable and unlikely to disintegrate or wobble; when disassembled, the toilet chair is significantly downsized by folding the legs and stacking up the other components.

1 . A combinative toilet chair, comprising left and right armrest frames, a seat frame provided between the two armrest frames and configured to support a vessel, and a backrest frame to be leaned against by a user, the combinative toilet chair being characterized in that:
 each said armrest frame has a front lower end and a rear lower end, wherein each of the front and rear lower ends is connected with a telescoping leg by a threaded connecting device, and an elastic band is connected inside and between each said leg and a corresponding said armrest frame, each said armrest frame having a front side fixedly provided with a tubular front insertion connector having a positioning hole, each said armrest frame further having a rear side pivotally provided with a freely rotatable rear insertion connector, wherein the rear insertion connector has an inner side and a rear side, each provided with an insertion portion having a positioning hole, and the insertion portion at the inner side of the rear insertion connector is threadedly provided with a fastener;   the seat frame comprises a front supporting member and a rear supporting member, and a holding frame is connected between the front and rear supporting members, wherein each of the front and rear supporting members has two ends, and each said end is provided with a resiliently retractable pin, the two ends of the front supporting member being insertable into the front insertion connectors of the armrest frames, respectively, the two ends of the rear supporting member being insertable into the insertion portions at the inner sides of the rear insertion connectors of the armrest frames, respectively; and   the backrest frame has two ends which are provided with resiliently retractable pins and are insertable into the insertion portions at the rear sides of the rear insertion connectors of the armrest frames, respectively.   
     
     
         2 . The combinative toilet chair of  claim 1 , wherein each said threaded connecting device comprises:
 an upper threaded element fixed at a corresponding said front or rear lower end of a corresponding said armrest frame; and   a lower threaded element mounted around an upper end of a corresponding said leg,   wherein each of the front and rear lower ends of the armrest frames is formed as an insertion end having a recess, and the upper end of each said leg is internally provided with a projection, such that after the insertion ends are respectively inserted into the legs, the recesses are respectively engaged with the projections, and the legs are securely connected to the armrest frames by threadedly coupling the corresponding upper and lower threaded elements together.   
     
     
         3 . The combinative toilet chair of  claim 1 , wherein each said leg comprises:
 a tubular leg member having an end provided with a resiliently retractable pin; and   a telescoping tubular leg member which is insertable by the tubular leg member and has a plurality of positioning holes.
