Abstract

A preflex, arcuately shaped blade head is formed of a cartridge having a cutting edge supported on a curved, flexible blade support. The blade head is oversized, being greater than 2¼″ in lateral linear length. An outrigger blade stabilizer extends posteriorly cantilevered from the blade support. A palm gripping handle forms a bulbous, palm accommodating shaped gripping member having a plan outline shaped generally of kite shape or an elongated Reuleax triangle, with a heel element forming a volar outer ridge at a distal end. An upper arcuate surface forms an oblique arch about the lateral plane of the handle. A longitudinal arch is further formed about the linear plane of the handle. A lower curved surface forms a finger receiving notch at a proximal end of the handle. Such features significantly extend the range of use of the shaver and is specifically adapted for shaving a user's scalp.

Claims (24)

1. A razor system, comprising:

an arcuately shaped blade head comprising

a replaceable, disposable cartridge having a curved cutting edge supported by a curved, flexible blade support, wherein said blade head is greater than 2¼″ in lateral linear length, and

an outrigger blade stabilizer extending posteriorly cantilevered from a mid-section of the blade support, wherein the curved blade support and the outrigger blade stabilizer form a curved guided shaving path to accommodate a shape of a skull, and

a palm gripping handle comprising a neck and a gripping member,

wherein the cartridge is removably connected to the neck of the handle;

wherein when not in use, portions of each of the cutting edge and blade support extend laterally outwardly and downwardly away from an end of the handle neck to which the cartridge is attached, and

wherein the palm gripping handle has an upper arcuate surface about a lateral plane, a longitudinal arch about a linear plane, and a lower curved surface including a notch at a proximal end and adapted to receive a finger, and

wherein the palm gripping handle further includes a gripping hole positioned on the longitudinal arch at the proximal end of the palm gripping handle, in front of the notch.

2. The razor system of claim 1 , wherein said palm gripping handle forms a bulbous, palm accommodating shaped gripping member having a plan outline of kite shape or an elongated Reuleax triangle, with a heel element forming a volar outer ridge at a distal end.

3. The razor system of claim 2 , wherein the upper arcuate surface forms an oblique arch about the lateral plane.

4. The razor system of claim 1 , wherein the blade support is segmented to allow the cutting edge to flex.

5. The razor system of claim 1 , wherein outermost edges of the blade support include lubricated guide tips.

6. A razor, comprising:

a pre-flexed, flexible, arcuately shaped blade head comprising a cartridge having a curved cutting edge supported on a curved, segmented flexible blade support in a natural state; and

an outrigger blade stabilizer extending posteriorly cantilevered from a mid-section of the blade support, wherein the blade support and the outrigger blade stabilizer form a curved guided shaving path to accommodate a shape of a skull,

said blade head being greater than 2¼″ in lateral linear length; and

a palm gripping handle forming a bulbous, palm accommodating shaped gripping member having an upper arcuate surface forming an oblique arch about a lateral plane of the handle and a longitudinal arch further formed about a linear plane of the handle, and a lower curved surface adapted as a finger receiving notch at a proximal end of the handle,

wherein the handle has a neck,

wherein the cartridge is removably connected to the neck of the handle; and

wherein when not in use, portions of each of the cutting edge and blade support extend laterally outwardly and downwardly away from an end of the handle neck, and

wherein the palm gripping handle further includes a gripping hole positioned on the longitudinal arch at a proximal end of the palm gripping handle, in front of the notch.

7. The razor of claim 6 , wherein said palm gripping handle forms a plan outline of kite shape or an elongated Reuleax triangle and further comprises a heel element forming a volar outer ridge at a distal end.

8. The razor of claim 6 , wherein said palm gripping handle further comprises a plan outline of kite shape or an elongated Reuleax triangle.
