摘要： A collapsible mobile chair assembly comprises a frame having a pair of axially aligned wheel axles 6, 7 extending from opposing sides of the frame, each axle 6, 7 having a rack gearing 40, 41 and being slidably mounted in said frame for axial moveable between an operating position in which it extends from and a storage position in which it is retracted into said frame. The rack gearing 40, 41 of the two axles 6, 7 overlap, extending on either side of and drivingly engaging a pinion gear 42 provided on the frame, thereby constraining the axles 6, 7 slidingly to move together in opposite directions. The assembly further includes two support plate assemblies 10, 11, one provided on each side of the chair, a rear fork assembly 12, 13 extending from each support plate assembly 10, 11, and a front fork strut 5a, 5b pivotally attached to each support plate 10, 11 for movement between an extended operational position and a retracted storage position. A handle strut 15a, 15b is pivotally attached to each support plate 10, 11 for movement between an extended operational position and a retracted storage position, each of said front fork struts 5a, 5b and said handle struts 15a, 15b having a gearing 22, 23 formed thereon, the gearing of the front fork struts 5a, 5b being respectively attached to said support plates 10, 11 and respectively engaging with the gearing of the handle struts 15a, 15b such that the handle strut and front fork strut associated with each support plate are constrained to rotate together between their extended and their retracted positions.

摘要： A collapsible chair frame 1 comprises a base 10 having longitudinally extending side bars 10a, 10b, with front mounting brackets 11a, 11b attached to one end of each side bar 10a, 10b. An actuation handle 13 is rotatably connected to the mounting bracket 11a, 11b so as to be rotatable relative thereto about a second axis parallel to but offset from said first axis, and one of a second pair of brackets 20a, 20b is secured to a second end of each side bar 10a, 10b. A front support bar 16, 17 extends from each side of said actuation handle 13 at an inclined angle substantially towards said second end of its respective side bar10a, 10b. A pair of rear support bars 21, 22 are rotatably connected to the second side brackets and extend at an inclined angle substantially towards said first end of its respective side bar 10a, 10b. Geared plates 18, 24 on ends of the support bars on each side of the frame engage with each other so as to contain the bars 21, 22 on each side to rotate together. The actuation handle 13 further includes locking pins 14 which secure said handle against rotation release means 34 being operable to release the handle 13 for rotation relative to said first pair of brackets.
