ABSTRACT:
This invention relates to a child walker-trainer. The walker-trainer consists of a frame preferably in the form of a push toy. At least three wheels are mounted to the frame. At least one of the wheels is mounted axially to the frame to form a rear wheel axis rearward of the other wheels. The invention preferably includes two rear wheels and two forward wheels. A handle attached to the frame extends upwardly and rearwardly of the rear wheel axis such that a downward force applied to the handle causes the walker-trainer to pivot along the rear wheel axis. The invention includes means for immobilizing the walker-trainer when a downward force is applied to the handle which causes the walker-trainer to pivot along the rear wheel axis. The immobilizing means preferably includes a flat, "U" shaped skid attached either to the frame or to the handle, such that it extends rearwardly of the rear wheel axis and is substantially parallel to and positioned slightly above the walking surface. A downward force applied to the handle causes the skid to engage the walking surface and immobilize the walker-trainer.
