Abstract

The invention relates to a three-wheel type multifunctional rollator. The technical scheme is that the front ends of two rollator frames (12) are symmetrically installed above a hinge support (14), a universal wheel (13) is installed below the hinge support, the rear ends of the rollator frames (12) are provided with rear wheels (11), the front ends of the rollator frames (12) are provided with horizontal petals (15), grab bars (1) are sleeved on vertical rods of the rollator frames (12), and the vertical rods of the rollator frames (12) can be folded through folding rotating shafts (9). A movable backrest (21) is installed on a back belt support (22) and can change positions in the forward and backward direction and achieve the functions of a chair wheel and a rest seat. A lifting rope (3) achieves the folding and unfolding of the rollator frames (12) by rotating rotary sleeves (5) arranged on two sides of a folding seat plate (4) around a transverse shaft (18) and by rotating the transverse shaft (18) around a vertical short shaft (19). A shopping bag (16) is installed below the folding seat plate (4) to achieve a shopping function. A baby carriage bucket (32) is additionally installed on the rollator frames (12) to achieve a baby carriage function. The foldable multifunctional rollator has the advantages of being simple in structure, strong in universality, convenient to fold, small in storage space and multiple in function.
