Foldable multifunctional rollator

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.

Description

technical field [0001] The invention belongs to the technical field of rolling aids. Specifically relates to a foldable multifunctional rollator. Background technique [0002] With the increase of the elderly population and the expansion of the scope of activities of the elderly in our country, the life of the elderly has received more and more attention from the society. In order to improve the self-care ability of the elderly, expand the scope of activities of the elderly, increase the opportunities for the elderly to live with infants and enrich the fun of life for the elderly, the multi-functional rollator will gradually become an auxiliary tool for the life of the elderly. [0003] At present, the rollator on the market has a single function, and is mostly used to assist users in walking, shopping and resting. The structure mostly adopts a four-wheel structure. The four-wheel structure has two folding methods for the frame: left and right and front and rear. That is, ...

[0003] At present, the rollator on the market has a single function, and is mostly used to assist users in walking, shopping and resting. The structure mostly adopts a four-wheel structure. The four-wheel structure has two folding methods for the frame: left and right and front and rear. That is, the cross frame connecting the left and right frames is used to realize the horizontal folding of the rollator, or the cross frame connecting the front and rear frames is used to realize the longitudinal folding of the rollator. The overall structure is complex, the parts are too many, and the manufacturing cost is high. High, large volume when folded and folded; when folding, you need to squeeze the cross frame first, change the angle of the cross frame to realize the folding of the rollator, and it is laborious to fold

It is difficult to fold the frame of the existing three-wheeled rollator directly, because the folding and rotating of the seat plate and the folding and rotating of the frame are not at the same point and in the same plane when folding, the two frames of the three-wheeled rollator surround the front When the fulcrum rotates, the frame and the seat plate interfere, so when the two frames of the existing three-wheeled rollator are folded, it is necessary to remove the seat plate from the frame and then fold the frame, resulting in a three-wheeled rollator. The retractable rollator is cumbersome and bulky when folded
