ABSTRACT:
An improved portable hair braider is provided which makes use of a plurality of hair grabbing members that extend transversely to the path of movement of the device over the top of the head. The invention hereof relates to the device described and claimed in U.S. Pat. No. 4,038,996, issued Aug. 2, 1977, to Eronini et al. The improvement hereof is specifically directed to a mechanical means for driving the ends of a plurality of grabbing members along a path in a plane perpendicular to their axes, wherein the path is defined as that of a figure eight. The hair grabbing members are caused to traverse or pass through a cross-over region formed by the intersection between two circular sections of the body of the device which is in the form of the figure eight.
The unique mechanical means for driving the hair grabbing members is accomplished by a plurality of rotatably moving paddles in intersecting and intermeshing relationship with a plurality of driven rudders which are at the remote ends of each of the grabbing members. The mechanical meshing relationship between the driving paddles and the driven rudders is designed to provide improved lateral rigidity between the paddles and rudders as the rudders pass through the cross-over region from one half of the figure eight pathway to the other half thereof. In the prior art device cited above significant looseness, hesitation or the like in the movement of the mechanical means may be experienced as the geared arrangement passes through the cross-over region of the device. The structural features and operational aspects of the present device overcome such prior art problems and difficulties to thereby provide a more efficient and smoother operating device having enhanced rigidity between the moving parts at points along the path traversed, which are characterized and recognized as somewhat critical to satisfactory operation of the prior art device.
