ABSTRACT:
A baby walker is provided with a substantially doughnut-shaped upper frame and a seat suspended from the upper frame by three straps. The end of each strap is provided with an engaging bar disposed at right angles with the direction of the length of the strap. The opposite ends of the engaging bar project beyond the widthwise ends of the strap. Attached to the lower surface of the upper frame are adjusting members each having a plurality of downwardly opened recesses. A guide member is provided adjacent each adjusting member and spaced apart from the lower surface of the upper frame. The straps are led from below the upper frame and mounted on the upper surfaces of the guide members, with the ends of the straps being led to the adjusting members. Each engaging bar engages one of the associated engaging recesses. In this state, the load on the seat forces the engaging bars into the innermost regions of the engaging recesses.
