Claims
- 1. A safety razor comprising a blade unit (2) including a guard having a guard surface, at least one blade (6) having a blade edge, at least one additional blade, and a cap behind said additional blade, and a handle (1) mounting the blade unit for pivotal movement in one direction only from a rest position about a pivot axis, characterized in that the pivot axis (C) underlies the guard surface (10) as seen in a direction normal to a plane (P) containing the guard surface (10) and the blade edge (12) adjacent thereto, and a rinsing space open to the underside of the blade unit and defined between the guard surface (10) and said cap and underlying said one blade and said additional blade, said rinsing space being substantially unobstructed by the handle to flow of rinsing water through said space when the blade unit is in the rest position.
- 2. A razor according to claim 1, wherein, when the blade unit is in the rest position, the handle is located entirely forwardly of a plane containing said blade edge of said at least one blade and perpendicular to said plane (P) containing the guard surface and said blade edge.
- 3. A razor according to claim 1, wherein, when the blade unit is in the rest position, the handle is located entirely forwardly of a plane containing the trailing edge of the guard surface (10) and perpendicular to said plane (P) containing the guard surface and said blade edge.
- 4. A razor according to claim 1, wherein the blade unit (2) is pivotable through an angle in the range of 35.degree. to 50.degree. preferably 40.degree. to 45.degree. from the rest position.
- 5. A razor according to claim 1 wherein, when the blade unit is in the rest position, said plane (P) containing the guard surface and said blade edge lies at an angle of 20.degree. to 30.degree. to the longitudinal axis of the handle.
- 6. A razor according to claim 1, wherein the pivot axis (C) is from 1.0 to 2.0 mm in front of said blade edge (12), measured in said plane (P) containing the guard surface and said blade edge.
- 7. A razor according to claim 1, wherein the pivot axis (C) is 0.50 to 1.00 mm below the guard surface.
- 8. A replaceable safety razor cartridge comprising
- a housing having a connecting structure for making a removable connection to a handle and a pivoting structure providing pivoting about a pivot axis,
- a guard at the front of said housing,
- a lubricating strip at the rear of said housing, and
- first, second, and third blades carried by said housing between said guard and said lubricating strip,
- whereby a user's beard is engaged sequentially by said guard, said first blade, said second blade, said third blade, and said lubricating strip during a shaving stroke,
- wherein said pivot axis is in front of said blades and below a plane that is tangent to said guard and said lubricating strip,
- said housing having a substantially unobstructed opening through it underneath said plane that is tangent to said guard and said lubricating strip, and wherein said first, second, and third blades are mounted in said opening.
- 9. The cartridge of claim 8 wherein each of said blades is disposed in a respective plane that is oriented at an acute blade angle to said plane that is tangent to said guard and said lubricating strip, and wherein said blades do not overlap each other.
- 10. The cartridge of claim 9 wherein said blades are mounted for movement with respect to said plane that is tangent to said guard and lubricating strip.
- 11. The cartridge of claim 8 wherein each of said blades is mounted on a bent support, each said bent support having a support portion and a base portion, said support portion being oriented at an acute blade angle with respect to said plane that is tangent to said guard and said lubricating strip, said base portion being generally perpendicular to said plane that is tangent to said guard and said lubricating strip.
- 12. The cartridge of claim 11 wherein each of said base portions is mounted in respective opposed slots in said housing on opposite sides of said opening.
- 13. The cartridge of claim 12 wherein said base portions are movable within said opposed slots.
