Abstract

A razor blade assembly has a handle, a head having a cutting blade assembly of one or more cutting blades connected to the handle; and a spacer which is mounted to or is formed as part of the head to space the cutting edges of the blades from the skin of a user to create and maintain a 5 o'clock shadow appearance beard in the range of 0.1 mm to 0.4 mm in thickness.

Claims (22)

1. A razor assembly comprising;

a head comprising a blade assembly comprising one or more cutting blades, wherein the head is configured to be attached to a handle;

wherein the head further comprises a spacer that, via a plurality of tapered-depth ribs, defines a distance of the one or more cutting blades from a skin surface;

wherein the spacer comprises a top wall and a bottom wall, wherein said bottom wall is positioned below the top wall and below an upper edge of the one or more cutting blades, wherein the plurality of tapered-depth ribs vary in thickness upon traversal between the top wall and the bottom wall and wherein the bottom wall forms a hair receiving surface that contacts the skin surface and that aligns hairs relative to the one or more cutting blades and wherein a first side wall traverses between the top wall and the bottom wall comprises a first resilient clip and a second side wall traverses between the top wall and the bottom wall opposite the first side wall comprises a second resilient clip, wherein the first resilient clip and the second resilient clip secure the spacer to the head and wherein a subset of the plurality of tapered-depth ribs define a plurality of middle cavities, which each has a vertical dimension between the top wall and the bottom wall and a horizontal dimension between the first side wall and the second sidewall and two outermost cavities disposed on each opposing end of the plurality of middle cavities, wherein each of the outermost cavities has vertical and horizontal dimensions greater than the vertical and horizontal dimensions of the plurality of middle cavities, respectively.

2. The razor assembly of claim 1 , wherein the head is removably attached to the handle.

3. The razor assembly of claim 1 , wherein the spacer is a cap which is adapted to space cutting edges of the blades from the surface.

4. The razor assembly of claim 3 , wherein the cap is removably attached onto the head.

5. The razor assembly of claim 4 , wherein the first side wall and the second side wall are parallel to each other and the top and bottom walls are perpendicular to each of the side walls.

6. The razor assembly of claim 1 , wherein each of the plurality of tapered-depth ribs has a beginning thickness in a range of 0.1 mm to 0.4 mm and an end thickness in a range of 0.1 mm to 0.4 mm and are adapted to create a beard thickness in the range of 0.1 mm to 0.4 mm.

7. The razor assembly of claim 1 , wherein the plurality of tapered-depth ribs are disposed perpendicular relative to the top wall and the bottom wall.

8. A spacer that defines a blade shaving clearance of an associated razor blade in relation to a skin surface, comprising:

a body having a first side wall, a second side wall, a rear wall and a front wall connecting the first side wall and the second side wall; a bottom wall extending from the front wall and a top wall extending from the rear wall; and a plurality of ribs extending from the front wall and the rear wall, wherein the plurality of ribs space an associated razor blade a predetermined distance from the skin surface to be shaved; the top wall and the plurality of ribs are tapered in depth between the rear wall and the front wall; wherein the top wall is positioned above the bottom wall along a shaving direction of the spacer thereby facilitating alignment and depth-controlled cutting of hair from the surface to be shaved; and wherein the first side wall comprises a first resilient clip and the second side wall comprises a second resilient clip, wherein the first resilient clip and the second resilient clip attach the spacer to an associated blade head and wherein a subset of the plurality of ribs define a plurality of middle cavities, which each has a vertical dimension between the top wall and the bottom wall and a horizontal dimension between the first side wall and the second sidewall and two outermost cavities disposed on each opposing end of the plurality of middle cavities, wherein each of the outermost cavities has vertical and horizontal dimensions greater than the vertical and horizontal dimensions of the plurality of middle cavities, respectively.

9. The spacer of claim 8 , wherein the first side wall and the second side wall are parallel to each other and the front and rear walls are parallel to each other and perpendicular to the first side wall and the second wall.

10. The spacer of claim 9 , wherein the first side wall and the second side wall are tapered between the front wall and the rear wall.

11. The spacer of claim 8 , wherein each of the ribs has a thickness in a range of 0.1 mm to 0.4 mm.

12. The spacer of claim 8 , wherein an upper surface of the bottom wall is spaced from a cutting edge of the razor blade.

13. A method of creating a shadow shave appearance on a skin surface of a user; comprising the following acts:

providing a razor assembly having a handle and a head comprising a blade; and

positioning a spacer onto the head to space the blade from the skin surface in a range of 0.1 mm thickness to 0.4 mm thickness, wherein the spacer has a top wall positioned above a bottom wall, and a plurality of depth-tapered ribs that traverse between the top wall and the bottom wall and wherein a first side wall traverses between the top wall and the bottom wall comprises a first resilient clip and the second side wall traverses between the top wall and the bottom wall opposite the first side wall comprises a second resilient clip, wherein the first resilient clip and the second resilient clip secure the spacer to the head and wherein a subset of the plurality of tapered-depth ribs define a plurality of middle cavities, which each has a vertical dimension between the top wall and the bottom wall and a horizontal dimension between the first side wall and the second sidewall and two outermost cavities disposed on each opposing end of the plurality of middle cavities, wherein each of the outermost cavities has vertical and horizontal dimensions greater than the vertical and horizontal dimensions of the plurality of middle cavities, respectively.

14. The method of claim 13 , wherein the first side wall and the second side wall are parallel to each other and the rear wall and the front wall are parallel to each other.

15. The method of claim 14 , wherein the plurality of ribs extend between the rear wall and the front wall wherein the ribs define depth of a cutting edge of the blade from the skin surface of the user.

16. The method of claim 15 , wherein each of the ribs has a variable thickness that varies in a range from 0.1 mm to 0.4 mm along a length of each of the plurality of depth-tapered ribs.
