A wheeled frame is provided including a lower horizontal main portion having a pair of opposite side rear wheels journalled therefrom and a pair of opposite side front caster wheels. The frame includes an upstanding handle assembly supported from the rear of the lower horizontal main frame portion and the upper end of the handle assembly includes a horizontal transverse handle portion. A horizontal transverse brake bar generally parallels and is supported from the handle portion beneath the latter and is guidingly shiftable toward and away from the handle portion. A brake member is shiftably supported from the frame for movement between applied and released positions and the brake member includes wheel braking portions engageable with the rear wheels to frictionally brake the latter when the brake member is in the applied position. Connecting structure is connected between the bar and the brake member operative to shift the latter toward the applied and release positions responsive to movement of the bar toward and away from the handle portion. The frame includes a horizontal seat forward of the handle assembly and the latter and seat are forwardly and downwardly swingable toward collapsed positions relative to the lower horizontal main frame portion.
