ABSTRACT:
A bath chair having elongated slots on opposite sides, legs secured to the seat, and a backrest mounted on two opposed L-shaped backrest support tubes, is provided with a pair of handrails secured to the seat by the horizontal segments of the backrest support tubes. Pairs of connecting tubes are mounted on opposite sides of the bottom face of the seat, each connecting tube having a cylindrical opening sized and disposed to receive respective horizontal segments of the backrest support tubes. The handrails are inserted through respective seat slots, each carrying a cylindrical member at its end disposed between and aligned with opposed connecting tubes. The horizontal segments of the backrest support tubes are inserted through the connecting tubes and the handrail cylindrical members therebetween so as to secure the handrail to the seat. Each handrail is formed with a sigmoidal segment between a vertically directed upper segment and a horizontally directed lower segment, to facilitate insertion through the respective elongated slot. In particular embodiments, the handrails are each formed of opposed tubular members and have grips that are either fixed or telescopically mounted with spring-loaded snap buttons and corresponding position holes to adjust their height.
