Patent ID: 8573610

Claim:
A device for assisting a user with mobility, comprising: a frame structure supported on a plurality of wheels rotatably attached to the frame structure, a seat member attached to the frame structure and a pair of footrest assemblies, each of the footrest assemblies including a supporting frame configuration supporting a foot plate, each of the supporting frame configurations including a connecting shaft rotatably inserted downwardly into an upper end of a respective one of a pair of vertical tubes affixed to a front end and at respective sides of the frame structure, to allow the supporting frame configuration to rotate about said one of the vertical tubes between a first angular position in which the supporting frame configuration extends forwardly to position the foot plate in front of the frame structure and a second angular position in which the supporting frame configuration is folded backward and adjacent a side of the frame structure, each of the connecting shafts having an annular radial shoulder resting on an annular surface of the upper end of the vertical tube to support a foot load, each of the connecting shafts including two elastically compressible spring-buttons, at least one of the spring-buttons being compressed radially inwardly into the connecting shaft by a cylindrical inner surface of the vertical tube when the supporting frame configuration is in any angular position about the vertical tube, and only one of the spring-buttons radially and outwardly extending from the connecting shaft into a hole in the vertical tube when the supporting frame configuration is in either one of the first and second angular positions.
