Ergonomically arcuate multi-blade razor
View Patent ↗A shaving device assembled with multiple blades having a generally planar portion and arcuate end portions in a generally parallel spaced relationship adapted for shaving curvilinear areas of a body.
1. A safety razor, comprising:
a razor head having a planar intermediate portion extending in a longitudinal direction along a generally horizontal plane and two generally arcuate end portions, each extending outwardly and downwardly from a respective end of the planar intermediate portion so that the planar intermediate portion and the arcuate end portions form a substantially inverted “U” shape with the planar intermediate portion between the arcuate end portions and adapted to position blade alignment guides at predetermined intervals to locate a plurality of blades in a desirable configuration;
blade alignment guides formed in the razor head and spaced apart from each other in a direction following the shape of the substantially inverted “U” for receiving and positioning of a plurality of substantially parallel blades for supporting same relative to an arcuate disposition thereof; and
a plurality of substantially parallel blades positioned within said blade alignment guides and following the shape of the substantially inverted “U”, each blade having a cutting edge and an intermediate, generally linear, planar portion and two, oppositely disposed, generally arcuate end portions, the cutting edge protruding outwardly from the blade alignment guides and following the shape of the substantially inverted “U” said cutting edge on the arcuate portions of the blade having a positive curvature extending from said generally linear portion.
2. The safety razor of claim 1 , having two substantially parallel blades.
3. The safety razor of claim 1 , having three substantially parallel blades.
4. The safety razor of claim 1 , having four substantially parallel blades.
5. The safety razor of claim 1 , in combination with a razor handle.
6. The combination of claim 5 , wherein said razor handle is made of a plastic, disposable material.
7. The combination of claim 5 , wherein said razor head is in a fixed position on the handle.
8. The combination of claim 5 , wherein said razor head is pivotable about an axis parallel to the cutting edges of the plurality of blades.
9. The safety razor of claim 1 , wherein said razor head is in the form of a detachable cartridge intended to be replaced when the cutting edges have become dulled.
10. The safety razor of claim 9 , in combination with a razor handle.
11. The combination of claim 10 , wherein said razor head is in a fixed position on the razor handle.
12. The combination of claim 10 , wherein said razor head is pivotable about an axis parallel to the cutting edges.
13. The safety razor of claim 1 , further including a lubricating strip along the front edge and the back edge of the razor head.
14. The safety razor of claim 1 wherein each blade is angled at a same angle as its adjacent blade.
15. A safety razor, comprising:
a plurality of substantially parallel blades each having a cutting edge and an planar intermediate, generally linear portion extending in a longitudinal direction along a generally horizontal plane and two, oppositely disposed, generally curved end portions each extending outwardly and downwardly from a respective end of the planar intermediate generally linear portion so that the planar intermediate generally linear portion and the generally curved end portions form a substantially inverted “U” shape with the planar portion between the generally curved end portions;
blade alignment guides formed in a razor head and following the shape of the substantially inverted “U” for receiving and positioning of said plurality of substantially parallel blades for supporting same relative to an angled disposition thereof; one related to another in generally parallel spaced relationship;
a razor head having a planar intermediate portion extending in a longitudinal direction along a generally horizontal plane and two generally curved end portions each extending outwardly and spaced apart from each other in a direction downwardly from a respective end of the planar intermediate portion of the razor head so that the planar intermediate portion of the razor head and the generally curved end portions of the razor head form a substantially inverted “U” shape with the planar portion of the razor head between the generally curved end portions of the razor head and adapted to position said blade alignment guides at predetermined intervals to locate said plurality of blades in a desirable configuration; and
a razor handle coupled to, and extending orthogonally from, the approximate longitudinal center of the razor head opposite the cutting edge of the blades.
16. The safety razor of claim 15 , having two substantially parallel blades.
17. The safety razor of claim 15 , having three substantially parallel blades.
18. The safety razor of claim 15 , having four substantially parallel blades.
19. The safety razor of claim 15 , wherein said razor head is in a fixed position with respect to the razor handle.
20. The safety razor of claim 15 , wherein said razor head is in a pivotable position with respect to the razor handle.
