ABSTRACT:
A foldable all-terrain baby stroller with an economical construction. The stroller has a tubular rear axle having left and right wheels mounted thereto and left and right laterally spaced-apart base frame members. The base frame members have flat forward end portions with a notch therein to receive the axle of a front wheel and flat rearward end portions with a hole therein sized to rotatably receive the rear axle. A spacer tube is coaxially mounted on the rear axle between the rearward portions of the base frame members to prevent inward movement thereof. Left and right upright frame members each have a lower end welded directly to the rear axle laterally outward of the rearward end portions of the corresponding left and right base frame members to prevent laterally outward movement thereof on the rear axle. Left and right inclined upper frame members are pivotally attached to the upper end portions of the corresponding upright frame members and have forward end portions which are rigidly connected together to move as a unit by an attachment member extending therebetween. A coupler is attached to the base frame members and has an upper plate and a lower plate spaced apart to define a substantially unobstructed receiver opening therebetween sized to releasably receive therein the forward end portions of the upper frame members and the attachment member. A lock pin is received within holes in the upper and lower coupler plates and the attachment member to releasably secure the forward end portions of the upper frame members in the receiver opening.
