Roller

Abstract

The invention discloses a walk assisting vehicle, comprising two symmetrically-arranged frames, wherein each frame comprises an upper bracket and a lower bracket, a supporting seat is arranged between the upper bracket and the lower bracket, a handrail is arranged at the upper end of the upper bracket, the lower end of the upper bracket is connected with the supporting seat, the lower bracket is hinged with the supporting seat, and both the supporting seat and the lower bracket are connected with wheels; a folding mechanism is arranged between the two frames and is hinged with the two frames respectively, two pull rods corresponding to the two lower brackets are connected to the folding mechanism, and the lower end of each pull rod is connected with the lower bracket corresponding to this pull rod; and when the folding mechanism is folded, the two pull rods drive the two lower bracket to fold upwards, and when the folding mechanism is unfolded, the two pull rods drive the two lower brackets to unfold downwards. The walk assisting vehicle can be folded or unfolded quickly, the operating time is short, and the operation is convenient.

Description

technical field [0001] The invention relates to a trolley, in particular to a rollator for assisting old people or patients to walk. Background technique [0002] A rollator is a trolley that can be pushed by hand. When the user is inconvenient, he can push the rollator while walking, and maintain the balance of the body while walking through the rollator. It is widely used to assist the elderly or patients to walk. In order to be easy to carry and store, most of the rollator vehicles in the prior art are foldable, and their structure generally includes two symmetrically arranged vehicle frames, and each vehicle frame includes an upper bracket and a lower bracket, and the upper bracket and the lower bracket There is a supporting base between them, the upper end of the upper bracket is provided with a handrail, and the lower end of the upper bracket is connected with the supporting base, the lower bracket is hinged with the supporting base, the supporting base and the lower b...

AI Technical Summary

Problems solved by technology

The above-mentioned rollator in the prior art generally needs to be folded in three steps when folding, that is, the first step is to fold up a lower bracket, the second step is to fold up the other lower bracket, and the third step is to fold the folding mechanism toward each other. ;Similarly, when unfolding, three-step operations must be carried out to make it unfold, so the operation of folding or unfolding is cumbersome and time-consuming, which cannot meet people's needs
