Claims
- 1. A guard for a safety razor blade unit, said unit having a rigid plastic housing to provide support for at least one blade and a cap structure, said guard comprising:an elastomeric strip disposed on said housing; and a backstop disposed on said housing between said elastomeric strip and a leading blade edge, said backstop including a rigid portion extending upwardly from said housing and a deformable portion capable of yielding resiliently under forces experienced during shaving; and wherein said deformable portion is supported against displacement in a direction towards the leading blade edge by said rigid portion of the backstop; and said deformable portion includes a lip extending over the top of said upwardly extending rigid portion, said lip being yieldable under the forces experienced during shaving to reduce the height of said backstop.
- 2. A guard according to claim 1, wherein the deformable portion is integral with the elastomeric strip.
- 3. A guard according to claim 2, wherein the lip of the deformable portion yields under shaving forces by being deflected.
- 4. A guard according to claim 2, wherein the lip of the deformable portion has a forward edge connected to the elastomeric strip, the lip being free to flex downwardly under shaving forces.
- 5. A guard according to claim 4, wherein the lip extends rearwardly from the upper end of an upwardly directed support portion which connects the lip to the elastomeric strip.
- 6. A guard according to claim 4, wherein the lip has a free trailing edge.
- 7. A guard according to claim 4, wherein downward deflection of the lip is limited by a stop.
- 8. A guard according to claim 1, wherein the rigid portion is a wall having a front face and a top face adjoining the front face, the lip of the deformable portion extending over the top face.
- 9. A guard according to claim 8, wherein the rigid wall is integral with the housing of the blade unit.
- 10. A guard according to claim 8, wherein the lip of the deformable portion is spaced above the top face of the rigid wall and is deformable by flexing downwardly.
- 11. A guard according to claim 8, wherein the lip of the deformable portion is in contact with the top face of the rigid wall and is resiliently compressible.
- 12. A guard according to claim 8, wherein the blade unit housing has a support surface on which the elastomeric strip is supported and the rigid wall is located at the rear of the support surface, the elastomeric strip having a rigid platform which secures the elastomeric strip to the support surface.
- 13. A guard according to claim 1, wherein the lip of the deformable portion yields under shaving forces by being compressed.
- 14. A safety razor having a blade unit with a guard as defined in claim 1.
- 15. A guard for a safety razor blade unit, said unit having a rigid plastic housing to provide support for at least one blade and a cap structure, said guard comprising:an elastomeric strip disposed on said housing; and a backstop disposed on said housing between said elastomeric strip and a leading blade edge, said backstop including a rigid portion and a deformable portion capable of yielding resiliently under forces experienced during shaving; and wherein said rigid portion is a wall having a front face and a top face adjoining the front face, the lip of the deformable portion extending over the top face and being connected to the elastomeric strip by a part extending upwardly from said elastomeric strip and in contact with at least an upper portion of the front face of the rigid wall; and said deformable portion includes a lip extending over the top of said rigid portion, said lip being yieldable under the forces experienced during shaving to reduce the height of said backstop.
- 16. A guard according to claim 15, wherein said deformable portion is supported against displacement in a direction towards the leading blade edge by said rigid portion of the backstop.
