Abstract

A prosthetic device comprising an upper member, and a lower member having a conical terminating section, the conical terminating section fitting into a conical void defined in the upper member. A prosthetic device kit, comprising an upper member and a number of lower members each having a conical terminating section in which the conical terminating sections of each lower member fit into a conical void defined in the upper member.

Claims

1. A prosthetic device comprising:

an upper member; and

a lower member having a conical terminating section, the conical terminating section fitting into a conical void defined in the upper member.

2. The prosthetic device of claim 1, in which the upper member selectively attaches to a terminating member of a prosthetic limb.

3. The prosthetic device of claim 1, in which the lower member selectively attaches to a prosthetic foot or shoe.

4. The prosthetic device of claim 1, in which the lower member comprises a self-aligning feature.

5. The prosthetic device of claim 4, in which the self-aligning feature comprises a protrusion extending radially from a common axis of the lower member and upper member, in which the protrusion prevents the lower member from mating at an incorrect radial angle to the upper member.

6. The prosthetic device of claim 5, in which the upper member includes a guiding track and a notch defined in the guiding track to receive the aligning feature.

7. The prosthetic device of claim 1, in which the upper member further comprises a locking mechanism to securely lock the upper member to the lower member.

8. The prosthetic device of claim 7, in which the locking mechanism comprises a spring loaded clip that locks the lower member to the upper member when the lower member is inserted into the upper member.

9. The prosthetic device of claim 1, in which the lower member has a conical terminating section which fits into a void defined in the second member.

10. A prosthetic device kit, comprising:

an upper member; and

a number of lower members each having a conical terminating section;

in which the conical terminating sections of each lower member fit into a conical void defined in the upper member.

11. The prosthetic device kit of claim 10, in which the upper member is selectively attachable to one of the prosthetic member devices.

12. The prosthetic device kit of claim 10, in which each of the lower members is selectively coupled to a prosthetic foot.

13. The prosthetic device kit of claim 10, in which each of the lower members comprises a self-aligning feature.

14. The prosthetic device kit of claim 13, in which the self-aligning feature comprises a protrusion extending radially from a common axis of the lower member and upper member.

15. The prosthetic device kit of claim 14, in which the upper member further comprises a guiding track that steers the self-aligning feature extending from any of the lower members into a guiding notch defined in the upper member.

16. The prosthetic device kit of claim 10, in which the upper member further comprises a securing device that secures the lower member to the upper member when the lower member is coupled to the upper member.

17. The prosthetic device kit of claim 16, in which the securing device comprises a locking clip that locks into place via a spring biased radially inward from a common axis of the lower member and upper member.

18. The prosthetic device kit of claim 10, in which the lower members comprise a conical section and the upper members comprise a inverse conical shaped void defined therein that allow the upper member and lower member to mate with each other.

19. An interlocking prosthetic device comprising:

an upper member selectively coupled at a proximal end to a terminating end of a prosthetic device; and

a lower member selectively coupled to a distal end of the upper member;

in which the distal end of the upper member comprises a conical void defined therein to receive a conical proximal end of the lower member.

20. The interlocking prosthetic device of claim 19, in which the lower member further comprises a self-aligning feature that is aligned with a guiding notch defined in the upper member.
