Abstract:
1. An attachment mechanism for repositionably attaching an object to a child-support apparatus, the attachment mechanism comprising: a repositioning track formed along the child-support apparatus; and a slide coupling that is repositionable along the track and to which the object can be attached, wherein the track includes a series of teeth and the coupling includes at least one tooth that mates with the track teeth so that the track and coupling teeth interlock to hold the coupling in place but can be disengaged to reposition the coupling and the objects attached thereto, wherein the track teeth extend substantially upward and, when the repositionable coupling is engaged with the track, the coupling tooth extends substantially downward, and wherein due to a combined weight of the coupling and the object the force of gravity moves the coupling tooth downward into interlocking engagement with the track teeth to retain the coupling in a locked position, the coupling can be moved upward to an unlocked position in which the track and coupling teeth are disengaged, the disengaged coupling can be slid along the track and repositioned, and the coupling can be released so that the force of gravity moves the coupling back into the locked position.
