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.
Claims19
A prosthetic device comprising:
- an upper member comprising;
- a guiding feature, comprising a sloped guiding track defined along a lip of a distal end of the upper member;
- and
- a lower member comprising:
- a conical terminating section formed at a proximal end of the lower member, the conical terminating section fitting into a conical void defined in the upper member and comprising a first conical part having a steeper angle than a second conical part relative to a common axis of the upper and lower members;
- a point of transition being formed between the first and second conical parts;
- a locking head coupled to a proximal end of the first conical part and fitting into a locking head void defined in the upper member;
- and
- a self-aligning feature comprising a protrusion extending radially from a section of the lower member and extending perpendicular to the common axis of the upper and lower members, in which the protrusion prevents the lower member from mating at an incorrect rotational position to the upper member;
- wherein contact of the self-aligning feature to the sloped guiding track as the conical terminating section is fitted into the conical void causes the lower member to rotate until the self-aligning feature is seated within a notch defined in the guiding feature.

An interlocking prosthetic device comprising:
- an upper member selectively coupled at a proximal end of the upper member to a terminating end of a prosthetic limb;
- and
- a lower member selectively coupled to a distal end of the upper member and coupled, at a distal end of the lower member, with a prosthetic foot device;
- 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;
- in which the conical proximal end of the lower member comprises:
- a first conical part having a steeper angle than a second conical part relative to a common axis of the upper and lower members;
- and a point of transition being formed between the first and second conical parts;
- and the lower member further comprising:
- a locking head coupled to the proximal end of the first conical part;
- in which the distal end of the upper member receiving the conical proximal end and locking head of the lower member is a monolithic piece;
- and
- in which the interlocking prosthetic device further comprises:
- a self-aligning feature comprising a protrusion protruding from the lower member perpendicularly to the common axis defined by the upper and lower members;
- and
- a guiding feature comprising a sloped guiding track defined in the distal end of the upper member and a guiding notch defined in the guiding feature, wherein the protrusion temporarily engages with the guiding track until the protrusion is seated within the guiding notch;
- wherein engagement of the protrusion with the guiding track via coupling of the upper member with the lower member causes the lower member to rotate about the common axis until the protrusion is seated within the guiding notch;
- and
- wherein the rotation of the lower member about the common axis aligns the prosthetic foot device with the prosthetic limb.

A prosthetic device kit, comprising:
- an upper member;
- and
- a number of lower members each having a conical terminating section at a proximal end thereof;
- each conical terminating section comprising a first conical part having a steeper angle than a second conical part relative to a common axis of the upper and lower members;
- in which the conical terminating section of each lower member fits into a conical void defined in the upper member;
- the conical void providing a fit with each of the first and second conical parts;
- in which a locking head is coupled to the proximal end of each of the lower members, each of the locking heads selectively fitting into a locking head void defined in the upper member;
- and
- in which each of the lower members comprises a self-aligning feature comprising a protrusion extending perpendicularly and radially from the common axis of the upper and lower members.
