Abstract

An adapter for coupling each of a razor handle and a razor cartridge together is provided. The adapter includes a cartridge engaging portion and a handle engaging portion.

First claim

What is claimed is:

1. An adapter for coupling each of a razor handle and a razor cartridge together, the adapter comprising:
a handle engaging portion comprising:
at least one wall that defines a receptacle for receiving a razor handle;
a first handle protrusion extending from the at least one wall; and
a second handle protrusion extending from the at least one wall and being spaced from the first handle protrusion;
wherein the first handle protrusion and the second handle protrusion are configured to extend into a first recess and a second recess, respectively, of a stem of a razor handle;

a cartridge engaging portion coupled with the handle engaging portion, the cartridge engaging portion comprising:
a stem that defines a recess for selectively engaging a cartridge protrusion; and
a collar slidably coupled with the stem and slidable between a resting position and an ejecting position;
wherein sliding the collar from the resting position to the ejecting position facilitates ejection of a cartridge from the stem.

2. The adapter of claim 1 wherein at least two walls comprise an upper wall and a lower wall and the first handle protrusion and the second handle protrusion extend from the lower wall.

3. The adapter of claim 2 wherein the handle engaging portion further comprises a pair of arms that extend from the lower wall.

4. The adapter of claim 3 wherein:
the first handle protrusion and the second handle protrusion are spaced apart by a first distance;
the pair of arms are spaced apart by a second distance; and
the first distance is less than the second distance.

5. The adapter of claim 1 wherein the stem defines a front recess and a rear recess.

6. The adapter of claim 1 wherein the cartridge engaging portion defines a notch that facilitates access to a cartridge for releasing of the cartridge from the adapter.

7. The adapter of claim 1 wherein the cartridge engaging portion is coupled with the handle engaging portion in a unitary one piece construction.

8. An adapter for coupling each of a razor handle and a razor cartridge together, the adapter comprising:
a handle engaging portion comprising:
at least one first wall that defines a first receptacle for receiving a razor handle;
a first handle protrusion extending from the at least one first wall; and
a second handle protrusion extending from the at least one first wall and being spaced from the first handle protrusion;
wherein the first handle protrusion and the second handle protrusion are configured to extend into a first recess and a second recess, respectively, of a stem of a razor handle;

a cartridge engaging portion coupled with the handle engaging portion, the cartridge engaging portion comprising:
at least one second wall that defines a second receptacle; and
a button assembly movably coupled with the at least one second wall and movable between a resting position and an ejecting position;
wherein moving the button assembly from the resting position to the ejecting position facilitates ejection of a cartridge from the cartridge engaging portion.

9. The adapter of claim 8 wherein at least two second walls comprise a second upper wall and a second lower wall and the second lower wall defines an elongate slot.

10. The adapter of claim 9 wherein the button assembly comprises a button that is pivotably coupled with the upper wall and facilitates pivoting of the button assembly between the resting position and the ejecting position.

11. The adapter of claim 10 wherein the button assembly further comprises an ejecting member coupled with the button and slidable in response to pivoting of the button between the resting position and the ejecting position.

12. The adapter of claim 8 wherein at least two first walls comprise a first upper wall and a first lower wall and the first handle protrusion and the second handle protrusion extend from the first lower wall.

13. The adapter of claim 12 further comprising a pair of arms that extend from the first lower wall.

14. The adapter of claim 13 wherein:
the first handle protrusion and the second handle protrusion are spaced apart by a first distance;
the pair of arms are spaced apart by a second distance; and
the first distance is less than the second distance.

15. The adapter of claim 14 wherein:
the first lower wall defines a pair of grooves that are spaced apart by a third distance; and
the second distance is less than the third distance.

16. The adapter of claim 15 further comprising a pair of end portions that each extend between the first upper wall and the first lower wall and are spaced apart by a fourth distance and the third distance is less than the fourth distance.

17. The adapter of claim 8 wherein the cartridge engaging portion is coupled with the handle engaging portion in a unitary one piece construction.

18. An adapter for coupling each of a razor handle and a razor cartridge together, the adapter comprising:
a handle engaging portion comprising:
at least one wall that defines a receptacle for receiving a razor handle;
a first handle protrusion extending from the at least one wall; and
a second handle protrusion extending from the at least one wall and being spaced from the first handle protrusion;
wherein the first handle protrusion and the second handle protrusion are configured to extend into a first recess and a second recess, respectively, of a stem of a razor handle; and

a cartridge engaging portion coupled with the handle engaging portion, the cartridge engaging portion comprising:
a first stem that defines a first recess for selectively engaging a first cartridge protrusion; and
a second stem that defines a second recess for selectively engaging a second cartridge protrusion; and

a button assembly movably coupled with one of the cartridge engaging portion and the handle engaging portion and movable between a resting position and an ejecting position wherein moving the button assembly from the resting position to the ejecting position facilitates ejection of a cartridge from the cartridge engaging portion.

19. The adapter of claim 18 wherein the at least one wall comprises an upper wall portion and a lower wall portion and the first handle protrusion and the second handle protrusion extend from the lower wall portion.

20. The adapter of claim 19 further comprising a pair of arms that extend from the lower wall.

21. The adapter of claim 20 wherein:
the first handle protrusion and the second handle protrusion are spaced apart by a first distance;
the pair of arms are spaced apart by a second distance; and
the first distance is less than the second distance.

22. The adapter of claim 21 wherein:
the lower wall defines a pair of grooves that are spaced apart by a third distance; and
the second distance is less than the third distance.

23. The adapter of claim 22 further comprising a pair of end portions that each extend between the upper wall and the lower wall and are spaced apart by a fourth distance and the third distance is less than the fourth distance.

24. The adapter of claim 23 wherein:
the first stem and the second stem are spaced apart by a fifth distance; and
the first distance is less than the fifth distance.

25. The adapter of claim 18 wherein the cartridge engaging portion is pivotally coupled with the handle engaging portion.

26. The adapter of claim 25 further comprising
