Abstract
An all-terrain baby stroller using an axle assembly that permits the stroller frame to be collapsible. The axle assembly has a coupler at each end of a tubular axle. Each coupler assembly employs two coupler members, one connected to an upright frame member and the tubular axle, and the other one connected to a horizontal frame member. The couplers are rotatably connected to each other by a hub member. A portion of one coupler rotatably fits within the other coupler, and the hub member extends coaxially through both couplers and allows the one coupler to rotate about it. A stub axle carrying one of the rear wheels is removably received within the hub member. A locking pin is inserted into a hole formed through the stub axle, hub member, an inward one of the couplers, and the tubular axle to releasably retain the stub axle in place. A pair of upper frame members is pivotally connected to the upright frame members and removably connected to the horizontal frame members to permit folding of the frame.
