Abstract
A mounting bracket for a prosthetic foot configured to attach to a residual limb, comprising an upper member, a lower member and compression torsion joint. The upper member comprises an upper flange, a mating post, and mounting portion configured to attach to the residual limb. The lower member comprises a mating portion, a lower flange, and a mounting portion configured to attach to the prosthetic foot. The compression torsion joint couples the upper member to the lower member and is configured to limit the vertical movement and torsional movement of the upper member with respect to the lower member.
Claims22
A mounting bracket for a prosthetic foot configured to attach to a residual limb, comprising:
- an upper member comprising an upper flange, a mating post, and a mounting portion configured to attach to the residual limb;
- a lower member comprising a mating portion, a lower flange, and a mounting portion configured to attach to the prosthetic foot, wherein the lower flange of the lower member comprises a pair of stops;
- and
- a compression torsion joint coupling the upper member to the lower member and configured to limit vertical movement and torsional movement of the upper member with respect to the lower member, comprising:
- an elastomeric ring configured to limit the vertical movement and torsional movement of the upper member with respect to the lower member;
- and
- a compression torsion bumper configured to limit the vertical movement and torsional movement of the upper member with respect to the lower member, wherein the compression torsion bumper contacts the stops to resist torsional movement of the upper member with respect to the lower member.

A mounting bracket for a prosthetic foot configured to attach to a residual limb, comprising:
- an upper member comprising:
- an upper flange with a channel;
- a mating post;
- and
- a mounting portion configured to attach to the residual limb;
- a lower member comprising:
- a lower flange with a channel, wherein the lower flange of the lower member comprises a pair of stops;
- a mating portion configured to receive the mating post;
- and
- a mounting portion configured to attach to the prosthetic foot;
- a compression torsion joint coupling the upper member to the lower member and configured to limit vertical movement and torsional movement of the upper member with respect to the lower member, comprising:
- an elastomeric ring having an upper surface coupled to the channel of the upper flange and a lower surface coupled to the channel of the lower flange;
- and
- a compression torsion bumper coupled to the upper flange of the upper member, wherein the compression torsion bumper contacts the stops to resist torsional movement of the upper member with respect to the lower member;
- and
- a retention system comprising:
- a cylindrical sleeve inserted within the mating portion of the lower member and configured to receive the mating post of the upper member to provide smooth vertical and torsional movement between the mating post of the upper member and the mating portion of the lower member;
- a plug coupled within a lower end of the mating post of the upper member;
- and
- a connector coupled to the plug and configured to contact a lower end of the lower member to attach the upper member to the lower member.

A prosthetic foot for use within a foot shell and configured to attach to a residual limb, comprising:
- a resilient bottom member comprising a front end, a rear end, and having no inflection point, wherein a center point of a radius of curvature of the front end of the resilient bottom member is above the resilient bottom member, and the rear end of the resilient bottom member is straight;
- a resilient top member comprising a front end and a rear end, wherein the front end of the resilient top member is connected to the front end of the resilient bottom member at a connection point, wherein the connection point is connected to an upper side of the rear end of the resilient top member, and wherein the resilient top member is positioned over the resilient bottom member;
- a bumper member directly attached to an underside of the rear end of the resilient top member, wherein the bumper member is detached from the upper side of the rear end of the resilient bottom member when the prosthetic foot is in an unloaded state;
- and
- a mounting bracket comprising:
- an upper member comprising an upper flange, a mating post, and mounting portion configured to attach to the residual limb;
- a lower member comprising a mating portion, a lower flange, and a mounting portion configured to attach to the rear end of the resilient top member, wherein the lower flange of the lower member comprises a pair of stops;
- and
- a compression torsion joint coupling the upper member to the lower member and configured to limit vertical movement and torsional movement of the upper member with respect to the lower member, comprising:
- an elastomeric ring configured to limit the vertical movement and torsional movement of the upper member with respect to the lower member;
- and
- a compression torsion bumper configured to limit the vertical movement and torsional movement of the upper member with respect to the lower member, wherein the compression torsion bumper contacts the stops to resist torsional movement of the upper member with respect to the lower member.
