1. A prosthetic apparatus, comprising:
an ankle support plate; a foot plate; a toe bumper assembly connecting a toe end of the ankle support plate to a toe end of the foot plate, the toe bumper assembly comprising a first sleeve, a first elastomeric snubber, and a first T-nut, the first elastomeric snubber residing between the toe end of the foot plate and the toe end of the ankle support plate, and the first sleeve passing through a mounting hole in the toe end of the ankle support plate and into a bore in the first elastomeric snubber, and the first T-nut passing through a mounting hole in the toe end of the foot plate, such that a first threaded fastener is passed through a bore in the first sleeve to engage a like-threaded section of the first T-nut to secure the toe end of the foot plate to the toe end of the ankle support plate, the first T-nut and the first elastomeric snubber defining a maximum and a minimum separation of the toe end of the foot plate from the toe end of the ankle support plate; and a heel bumper assembly connecting a heel end of the ankle support plate to a heel end of the foot plate, the heel bumper assembly comprising a second sleeve, a second elastomeric snubber, and a second T-nut, the second elastomeric snubber residing between the heel end of the foot plate and the heel end of the ankle support plate, and the second sleeve passing through a mounting hole in the heel end of the ankle support plate and into a bore in the second elastomeric snubber, and the second T-nut passing through a mounting hole in the heel end of the foot plate, such that a second threaded fastener is passed through a bore in the second sleeve to engage a like-threaded section of the second T-nut to secure the heel end of the foot plate to the heel end of the ankle support plate, the second T-nut and the second elastomeric snubber defining a maximum and a minimum separation of the heel end of the foot plate from the heel end of the ankle support plate. |
