Patent attributes
A push apparatus attachment can include a frame connecter for connecting at two points to a push apparatus frame; a height-adjustment frame pivotally connected to the frame connector; and a pivot assembly structured and configured to be gripped by a user's hands. The pivot assembly can include a swing bar pivotally connected to the height-adjustment frame and a grip bridge having at least two hand grips, one on each end of the grip bridge, the grip bridge being pivotally connected to the swing bar. The various pivot connections enable the device to accommodate users of different heights, enable the pivot assembly to remain parallel to the ground when the height-adjustment frame rotates relative to the frame connector, and enable free movement of the outer ends of the grip bridge in three dimensions to allow for a user to maintain natural running form while pushing the push apparatus.
