Abstract
Abstract A shaving implement for raising and holding low-lying hairs in an erect position for cutting by a blade edge and for distributing shaving force which includes resilient hair raising means spring mounted on a flange having a skin contacting surface or guard member adapted to distribute shaving force to substantially prevent stretching of a user's skin. The resilient hair raising means have barbed ends projecting beyond and substantially normal to the skin contacting surface of the flange in close proximity to the blade edge.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
91 words
A shaving implement comprising: a handle; a blade having a cutting edge; means for supporting said blade, said blade supporting means being attached to said handle and having a flange with a skin contacting surface adapted to distribute shaving force to substantially prevent stretching of said skin; resilient hair raising means mounted on said flange immediately adjacent to said blade cutting edge for raising and holding hairs in an erect position for cutting by said blade cutting edge; and spring means mounted on said implement for biasing the hair raising means.
Claim 2
Dependent Claim
91 words
A shaving implement comprising: a handle; a blade having a cutting edge; means for supporting said blade, said blade supporting means being attached to said handle and having a flange with a skin contacting surface adapted to distribute shaving force to substantially prevent stretching of said skin; resilient hair raising means mounted on said flange immediately adjacent to said blade cutting edge for raising and holding hairs in an erect position for cutting by said blade cutting edge; and spring means mounted on said implement for biasing the hair raising means.
Claim 3
Dependent Claim
45 words
A shaving implement according to claim 1, wherein said blade supporting means include a guard member and a cap arranged to support said blade assembled therebetween, said cap being adapted to cooperate with said skin contacting surface of said flange to distribute said shaving force.
Claim 4
Dependent Claim
205 words
A shaving implement comprising: a handle; a blade having a cutting edge; means for supporting said blade, said blade supporting means being attached to said handle and having a flange with a skin contacting surface adapted to distribute shaving force to substantially prevent stretching of said skin; and resilient hair raising means spring mounted on said flange immediately adjacent to said blade cutting edge for raising and holding hairs in an erect position for cutting by said blade cutting edge, said spring mounted resilient hair raising means include a plurality of resilient filaments each having one end attached to a rigid bar and an unattached barbed end opposite said one end, said bar being assembled to said blade supporting means with said barbed end projecting beyond and substantially normal to said surface of said skin contacting flange, adjacent to said cutting edge; and leaf spring means attached to said blade supporting means and coupled to said bar to cause said bar to reciprocally move along a linear path in a plane substantially normal to said flange surface when said flange is moved across said skin, whereby said barbed filament end raises and holds said hairs in an erect position for cutting by said cutting edge.
Claim 5
Dependent Claim
205 words
A shaving implement comprising: a handle; a blade having a cutting edge; means for supporting said blade, said blade supporting means being attached to said handle and having a flange with a skin contacting surface adapted to distribute shaving force to substantially prevent stretching of said skin; and resilient hair raising means spring mounted on said flange immediately adjacent to said blade cutting edge for raising and holding hairs in an erect position for cutting by said blade cutting edge, said spring mounted resilient hair raising means include a plurality of resilient filaments each having one end attached to a rigid bar and an unattached barbed end opposite said one end, said bar being assembled to said blade supporting means with said barbed end projecting beyond and substantially normal to said surface of said skin contacting flange, adjacent to said cutting edge; and leaf spring means attached to said blade supporting means and coupled to said bar to cause said bar to reciprocally move along a linear path in a plane substantially normal to said flange surface when said flange is moved across said skin, whereby said barbed filament end raises and holds said hairs in an erect position for cutting by said cutting edge.
Claim 6
Dependent Claim
31 words
A shaving implement according to claim 3, wherein an end of said leaf spring is arranged to flexibly press said bar against a flange surface opposite said skin engaging flange surface.
Claim 7
Dependent Claim
24 words
A shaving implement according to claim 1, wherein said barbed filament end is located no more than 0.064 inch from said blade cutting edge.
