Abstract
Segmented guard bar wherein segments of adjacent guard bars are tapered such that the skin flow through spaces between the segments is reduced. According to one preferred, illustrated embodiment, the distance between the rearward portion of adjacent segments is less than the space between the forward portions of those segments. Though not limited to any specific type of razor, the present invention is particularly suited for use with a flexible razor head having a cap member, at least one and preferably two blades separated by a spacer, 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.
Claims18
A guard bar for use with a razor head comprising:
- a plurality of segments disposed for engagement with a surface being shaved, said segments comprising a face engaging portion and a rearward portion, said segments being at least partially separated from adjacent segments thereby providing a space therebetween;
- and
- at least one of said segments comprising a tapered side portion for controlling the flow of skin through said space between said segments wherein said tapered side portion tapers rearwardly and laterally such that opposing portions of said segments are closer toward the rear of said segments than at the face engaging portions.
A razor 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 for controlling the flow of skin through at least one space between said segments, at least two of said segments being spaced by a distance of about 0.003-0.015 inches at the closest points of said segments for controlling the flow of skin through said space between said segments;
- wherein at least one pair of adjacent guard member segments comprise opposed tapered side portions and wherein said tapered side portion tapers rearwardly and laterally.
A guard bar for use with a razor head whereby said razor head is moved along a shaving path on a surface being shaved, said guard bar comprising:
- a plurality of segments disposed for engagement with a surface being shaved;
- and
- at least two of said segments having a space therebetween defined by opposing sidewalls of said segments, wherein the entire height of each of said sidewalls is disposed at an angle to said shaving path and wherein said opposing sidewalls are separated by a distance of about 0.003-0.015 inches.
A guard bar for use with a razor head comprising:
- a plurality of segments disposed for engagement with a surface being shaved, said segments comprising a face engaging portion and a rearward portion, said segments being at least partially separated from adjacent segments thereby providing a space therebetween;
- and
- at least one of said segments comprising a lateral extension which extends into said space thereby providing an obstruction to the flow of skin therethrough.
