ABSTRACT:
A comb assembly for an electric dry shaver is provided with a perforated central comb panel and two end comb panels disposed adjacent the edges of the central comb panel and having long hair slots. The end panels and the central comb panels are separately fabricated from stock materials of different predetermined thicknesses and assembled to form an accurate and smoothly interfitting comb assembly. Thus, the thickness of the central comb panel is determined independent of the end comb panel thickness. The central comb panel, fabricated from a stock material of a uniformly thinner thickness than that of the end panels, requires no grinding in the fabrication of the comb and thus results in a more uniform thinner comb than obtained with grinding operations.
The separately fabricated, flexible central and end comb panels, after being fabricated with the desired predetermined patterns of perforations and elongated slots, are secured over a multiply arched comb support structure which includes a number of thin support ribs. The central and end comb panels are secured to the comb support structure by integrally formed retaining clip portions that interfit with corresponding extending tabs of the comb support structure.
The assembled comb structure is accurately positioned and releasably secured to the head of the shaver at the center of the shaver head by a latch member attached to the comb support frame and interfitting with a slidably arranged comb catch member.
