Abstract

A razor blade assembly has a body member containing blade means which may be resiliently mounted and biased outwardly from the body member. A wrap-around clip is provided at both sides of the body member, the clip having its ends terminating at the bottom surface of the body member. Means are provided for inhibiting movement of the clip ends relative to the bottom surface upon impact loading of the razor blade assembly.

Claims

1. A razor blade assembly comprising:

a body member having at least one pair of slotted openings formed therein, one of said slotted openings being disposed at each of opposite side portions of said body member;

a razor blade disposed in said openings;

a pair of clips one disposed at one side portion and another disposed at the opposite side portion of said body member;

each said clip enveloping a respective said side portion and covering a portion of said slotted opening and extending completely across said blade in a direction transverse to the extent of said blade in the area of said slotted opening to retain said blade in said slotted opening;

each said clip further having a pair of end portions terminating along a bottom surface of its respective said body member side portion; and

means disposed adjacent each of said end portions for inhibiting movement of one of said pair of clip end portions relative to said body member bottom surface in a direction transverse to the longitudinal direction of said blade to prevent separation of said pair of clip end portions one from the other.

2. A razor blade assembly as set forth in claim 1 wherein said means for inhibiting said movement of a said pair of clip end portions comprises an interfitting engagement between a clip end portion surface and said body member bottom surface, one of said surfaces having a contoured boss extending outwardly therefrom and a corresponding contoured opening formed in the surface of the other for receiving said boss.

3. A razor blade assembly as set forth in claim 2 wherein said boss is formed on said body member bottom surface and said contoured opening is formed in said clip end portion.

4. A razor blade assembly as set forth in claim 3 wherein said boss is formed of a radial surface extending toward, and received in an edge of said clip end portion.

5. A razor blade assembly as set forth in claim 3 wherein said boss is cylindrical and said clip end portion has a circular opening formed therein for receiving said boss.

6. A razor blade assembly as set forth in claim 1 wherein said body member contains at least one other pair of slotted openings formed therein at said opposite side portions of said body member, said pair of slotted openings having a second razor blade disposed therein.

7. A razor blade assembly as set forth in claim 6 which further includes spring fingers formed in said body member for spring-biasing said razor blades by contacting each of said razor blades to force said blades upwardly into contact with each of said clips.

8. A razor blade assembly as set forth in claim 6 wherein said means for inhibiting said movement of a said pair of clip end portions comprises an interfitting engagement between a clip end surface and said body member bottom surface, one of said surfaces having a contoured boss extending outwardly therefrom and a corresponding contoured opening formed in the surface of the other for receiving said boss.

9. A razor blade assembly as set forth in claim 8 wherein said boss is formed on said body member bottom surface and said contoured opening is formed in said clip end portion.

10. A razor blade assembly as set forth in claim 9 wherein said boss is formed of a cylindrical surface extending toward, and received in one edge of said clip end portion.

11. A razor blade assembly as set forth in claim 10 which further includes spring fingers formed in said body member for spring-biasing said razor blades by contacting each of said razor blades to force said blades upwardly into contact with each of said clips.

12. A razor blade assembly as set forth in claim 1 wherein means for inhibiting movement of a said pair of clip end portions comprises a slot formed in said body member bottom surface in the longitudinal direction of said blade and wherein said clip end portion is formed for interfitting engagement in said slot.
