Abstract
A prosthetic device and related methods having height adjustment features. A prosthetic foot includes an elongate support member comprising fiber reinforced material and having a support surface configured to rest upon a ground surface prior to use, an adapter mounted to the support member and configured to secure the prosthetic foot to another prosthetic device, and a height adjustable feature configured to adjust a height of the adapter relative to the support surface.
Claims22
A prosthetic foot, comprising:
- an elongate support member comprising fiber reinforced material and having a support surface configured to rest upon a ground surface prior to use;
- an adapter mounted to the support member and configured to secure the prosthetic foot to another prosthetic device;
- and
- a height adjustable feature configured to adjust a height of the adapter relative to the support surface, wherein the height adjustable feature includes an adapter support to which the adapter is mounted, and a bolt extending through the support member and into engagement with the adapter support to releasably secure the adapter support to the support member, wherein the adapter support includes a contoured portion, the contoured portion facing a surface of the support member and configured to contact the support member during use of the prosthetic foot to alter a moment arm length between the bolt and adapter support, and wherein the contoured portion comprises a curved surface configured to contact the support member.
1 more element
A prosthetic foot, comprising:
- a spring assembly having a first portion extending horizontally and arranged to contact a ground surface, and a second portion having an adapter mounting portion;
- and
- an adapter assembly comprising:
- a connector configured to releasably secure the prosthetic foot to a prosthetic device;
- a base portion interposed between the connector and the spring assembly;
- at least one fastener to releasably secure the adapter assembly to the spring assembly;
- and
- a height adjustable feature configured to adjust a height of the adapter assemble relative to the spring assembly, wherein the height adjustable feature includes an adapter support to which the adapter assembly is mounted, and the at least one fastener extends through the spring assembly and into engagement with the adapter support to releasably secure the adapter support to the spring assembly, wherein the adapter support includes a contoured portion, the contoured portion facing a surface of the spring assembly and configured to contact the spring assembly during use of the prosthetic foot to alter a moment arm length between the at least one fastener and adapter support, and wherein the contoured portion comprises a curved surface configured to contact the spring assembly;
- wherein the prosthetic foot is operable to adjust an effective height of the connector relative to the ground surface.
6 more elements
A method of adjusting an effective height of a prosthetic device, comprising:
- providing a prosthetic device comprising an elongate composite spring member, an adapter, and a height adjustable feature interposed between the spring member and the adapter, wherein the height adjustable feature includes an adapter support to which the adapter is mounted, and a bolt extending through the elongate composite spring member and into engagement with the adapter support to releasably secure the adapter support to the elongate composite spring member, wherein the adapter support includes a contoured portion, the contoured portion facing a surface of the elongate composite spring member and configured to contact the elongate composite spring member during use of the prosthetic device to alter a moment arm length between the bolt and adapter support, and wherein the contoured portion comprises a curved surface configured to contact the elongate composite spring member;
- and
- operating the height adjustable feature to move the adapter relative to the spring member to adjust an effective height of the adapter.
A method of adjusting an effective height of a prosthetic foot, comprising:
- providing a prosthetic foot comprising an elongate composite spring assembly having a first portion configured to contact a ground surface and a vertically arranged portion, an adapter, and a height adjustable feature interposed between the vertically arranged portion and the adapter, wherein the height adjustable feature includes an adapter support to which the adapter is mounted, and a bolt extending through the elongate composite spring assembly and into engagement with the adapter support to releasably secure the adapter support to the elongate composite spring assembly, wherein the adapter support includes a contoured portion, the contoured portion facing a surface of the elongate composite spring assembly and configured to contact the elongate composite spring assembly during use of the prosthetic foot to alter a moment arm length between the bolt and adapter support, and wherein the contoured portion comprises a curved surface configured to contact the elongate composite spring assembly;
- and
- adjusting a position of the adapter relative to the elongate composite spring assembly with the height adjustable feature to change a height of the adapter relative to the ground surface.
