Abstract
Abstract A razor head comprising a support structure having side portions positioned outside the cutting path of the blade edges and which are formed of a resilient material, for example, a synthetic rubber-like compound. By positioning resilient material in skin-engaging contact on the sides of the razor head support structure outside the cutting path of the blades, a soothing sensation is advantageously imparted to the shaving process and a higher degree of control over the skin as the skin flows over the blades, is attainable. Another aspect of the present invention comprises, a resilient material utilized in the construction of the support structure at a pivotal connection between two relatively movable members in order to dampen vibrations. Other embodiments comprise a plurality of operatively connected blades.

Claim 1
Independent Claim
131 words
A razor head comprising: a support structure; at least one blade movably supported relative to said support structure, said blade having a sharpened edge which defines a cutting path when said razor head is drawn across a skin surface during shaving; said blade operatively connected to said support structure by means for movably connecting said blade to said support structure; said connecting means comprising at least one portion formed of a resilient material; wherein said connecting means comprises a blade support connected to said blade, said blade support comprising a pin; said connecting means further comprising a receptacle for receiving said pin, defined by said support structure; wherein at least one of said pin or said receptacle comprise a resilient material; and wherein said blade support pin has a semi-circular cross-section.
Claim 2
Dependent Claim
131 words
A razor head comprising: a support structure; at least one blade movably supported relative to said support structure, said blade having a sharpened edge which defines a cutting path when said razor head is drawn across a skin surface during shaving; said blade operatively connected to said support structure by means for movably connecting said blade to said support structure; said connecting means comprising at least one portion formed of a resilient material; wherein said connecting means comprises a blade support connected to said blade, said blade support comprising a pin; said connecting means further comprising a receptacle for receiving said pin, defined by said support structure; wherein at least one of said pin or said receptacle comprise a resilient material; and wherein said blade support pin has a semi-circular cross-section.
Claim 3
Dependent Claim
131 words
A razor head comprising: a support structure; at least one blade movably supported relative to said support structure, said blade having a sharpened edge which defines a cutting path when said razor head is drawn across a skin surface during shaving; said blade operatively connected to said support structure by means for movably connecting said blade to said support structure; said connecting means comprising at least one portion formed of a resilient material; wherein said connecting means comprises a blade support connected to said blade, said blade support comprising a pin; said connecting means further comprising a receptacle for receiving said pin, defined by said support structure; wherein at least one of said pin or said receptacle comprise a resilient material; and wherein said blade support pin has a non-circular cross-section.
Claim 4
Dependent Claim
131 words
A razor head comprising: a support structure; at least one blade movably supported relative to said support structure, said blade having a sharpened edge which defines a cutting path when said razor head is drawn across a skin surface during shaving; said blade operatively connected to said support structure by means for movably connecting said blade to said support structure; said connecting means comprising at least one portion formed of a resilient material; wherein said connecting means comprises a blade support connected to said blade, said blade support comprising a pin; said connecting means further comprising a receptacle for receiving said pin, defined by said support structure; wherein at least one of said pin or said receptacle comprise a resilient material; and wherein said blade support pin has a non-circular cross-section.
