Baby stroller frame

An all terrain baby stroller using an axle assembly that allows the rear wheels to be easily and quickly mounted and removed from the stroller frame without tools. The axle assembly has each rear wheel rotatably mounted on an outward end portion of a stub axle. A tubular rear axle defines a cylindrical interior chamber with an outward end opening sized to slidably receive the stub axle inward end portion therethrough for positioning of the stub axle inward portion coaxially within the interior chamber. When so positioned, a circumferential groove of the stub axle inward end portion is positioned within the interior chamber. The tubular sidewall of the rear axle has an aperture positioned axially inward from the interior chamber outward opening and at a location to coincide with the circumferential groove. A lock pin is carried by a strip spring and is movably disposed in the sidewall aperture for selective movement between an engagement position and a disengagement position. In the engagement position the pin extends into the interior chamber and into the circumferential groove of the stub axle inward end portion to prevent axial withdrawal of the stub axle from the interior chamber. When in the disengagement position, the pin is sufficiently clear of the circumferential groove to permit the stub axle inward end portion to be axially inserted into and removed from the interior chamber.
