Abstract
A segmented guard bar and skin flow control members disposed in the spaces between the guard bar segments. Though not limited to any specific type of razor, the present invention is particularly suited for use with a flexible safety razor having a cap member at least one and preferably two blades separated by a spacer, and a blade seat having a plurality of blade support portions separated by corrugations and a segmented guard bar with each segment independently connected to the blade support portions. Skin flow control members having at least one groove join the adjacent guard bar segments.
Claims12
A razor head comprising:
- a cap member;
- at least one blade having a sharpened edge;
- a blade seat for supporting said blade comprising a plurality of blade supports wherein adjacent blade supports are separated by a corrugation;
- a guard member comprising a plurality of segments disposed forwardly of said sharpened edge, each of said segments comprising a face engaging portion and a rearward portion, each of said segments being separate from adjacent segments thereby providing a space therebetween;
- means for attaching said segments to said blade seat;
- and
- means for controlling the flow of skin through at least one space between said segments.
- wherein said segments comprise sidewalls and said controlling means comprises a web extending from said sidewalls on adjacent segments;
- and
- wherein said web has at least one groove located thereon.
A head head comprising:
- at least one blade having a sharpened edge;
- a blade seat for supporting said blade;
- a guard member comprising a plurality of segments disposed forwardly of said sharpened edge, each of said segments being separate from each adjacent segment thereby providing spaces therebetween;
- means for attaching said segments to said blade seat;
- and
- means for controlling the flow of skin through at least one space between said segments;
- wherein said segments comprises sidewalls and said controlling means comprises at least one web extending from sidewalls on adjacent segments;
- wherein said web connects upper, rearward portions of said sidewalls;
- wherein said web has a substantially fixed length;
- and
- wherein said web has at least one groove located thereon.
A flexible guard bar for a flexible razor head, comprising:
- a plurality of segments forwardly disposed for engagement with a skin surface being shaved, each of said segments comprising a forward skin engaging portion and a rearward portion, each of said segments being separated from adjacent segments, and having side walls thereby providing a space therebetween;
- and
- means for controlling skin flow through at least one space between at lest one pair of said segments;
- wherein said controlling means comprises a unitary web comprising a plurality of skin flow control means disposed along a plurality of said segments;
- wherein said skin flow control means are substantially U-shaped and said web is disposed such that the base of said web is disposed forwardly of the point where said web contacts said side walls of said at least one pair of said segments;
- and
- wherein said web has at least one groove located substantially on the upper edge of said web.
