Folding bristle hairbrush

A hairbrush comprising:

• a base enclosure, the base enclosure having opposing speed sidewalls and an integral bottom surface;
• a handle hingedly connected to the base enclosure sidewalls;
• a plurality of spaced bristle bars, each bristle bar comprising a shaft and a plurality of bristles, the bristles attached to the shafts, the bristle bars extending between the base enclosure sidewalls, and the bristle bars being pivotally mounted within the base enclosure sidewalls;
• an interconnecting means for conveying rotational energy from the handle to the bristle bars, thereby extending the bristles from within the base enclosure when the handle is extended from the base enclosure;
• and
• a latching means, interacting with the handle and base enclosure, for securing the handle in the extended position, thereby securing the bristles into the extended position, wherein the latching means comprises
• a cog, the cog having a cylindrical head attached to a cylindrical body, the cog head equipped with a series of ratchet-like protrusions, the cog equipped with counterbored holes on each end, the sidewalls of the base enclosure terminating with cylindrical protrusions counterbored in such a fashion as to mate with the ratchet-like protrusions of the cog;
• a pushbutton, the pushbutton comprising a non-circular shaped head attached to a shaft body, the shaft body transitioning from a circular cross-section at the pushbutton head, to a non-circular cross-section at the opposite end;
• and
• an urging means compressing the cog into the base enclosure.
