Definitions
- the present invention relates to a prosthetic foot apparatus and more particularly to a gasket cover surrounding an endoskeletal prosthetic foot apparatus.
- Some modern prosthetic leg and feet apparatus consist of numerous metallic components connected together to simulate a human foot, ankle, and lower leg. The components primarily include a method of attaching a prosthetic foot to an endoskeletal pylon tube including several fasteners, bushings, and inserts providing the rotation, flexibility, and force bearing properties of the foot, ankle, and lower leg. Modern prosthetic feet have also evolved to include many complex components that are primarily covered by a foot shell, but they may be exposed at the top of the foot around the foot, ankle, and lower leg connection.
- the endoskeletal leg, ankle, and foot components are covered by a cosmetic cover simulating the external look of a full human leg.
- the cover is usually constructed of synthetic materials and connected to a socket at the top of the leg and to a top portion of the foot assembly. Creating the cover and connecting i to the socket and foot assemblies is often difficult and time consuming. The cover also reduces access to the components for making adjustments and performing maintenance. [0003] More often, the modern endoskeletal apparatus is left uncovered. The endoskeletal components have become more socially acceptable to look at without a cover and thus the components have been left exposed. Leaving the components uncovered also allows for easy access to make adjustments or to perform maintenance.
- One aspect of the present invention is a prosthetic foot gasket for sealing between a foot shell covering a foot portion of an endoskeletal prosthetic leg and a leg portion thereof.
- the gasket comprises a peripheral body having an upper surface and further defining a central opening therethrough.
- a lip extends from a bottom of the body and in combination with the body defines a groove therearound for receiving a top portion of the foot shell.
- a seal is affixed to an upper surface of the body for sealing engagement with the leg portion of the prosthetic leg.
- a prosthetic leg comprising a leg portion and a foot and ankle portion affixed to a bottom of the leg portion.
- a foot shell covers the foot and ankle portion wherein the foot shell is made from a resilient material.
- a gasket is in sealing engagement with a top of the foot shell and extends to the leg portion wherein the gasket is also in sealing engagement with the leg portion.
- Figure 1 is a perspective view of a representative endoskeletal leg and foot prosthesis showing foot shell covering the foot portion of the prosthesis.
- Figure 2 is the endoskeletal leg prosthesis of Figure 1 with a gasket according to the present invention installed thereon.
- Figure 3 is an elevational cross-section of the leg prosthesis and gasket of Figure 2.
- Figure 4 is a perspective view of the endoskeletal leg prosthesis wherein an upper surface of the gasket is adapted for bonding to a cosmetic leg covering.
- DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT [0011]
- the terms "upper”, “lower”, “left”, “rear”, “right”, “front”, “vertical”, “horizontal”, and derivatives thereof shall relate to the invention as oriented in Figure 3. However, it is to be understood that the invention may assume various alternative orientations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the inventive concepts defined in the appended claims.
- FIG. 1 shows a representative endoskeletal prosthetic leg 10.
- Endoskeletal prosthetic leg 10 generally comprises a leg portion 12 which has an endoskeletal tube 18 with a leg socket adapter 26 affixed to a top portion thereof and a tube adapter 20 affixed to a lower portion thereof.
- Socket adapter 26 attaches to a leg socket (not shown) which receives a user's leg therein.
- tube adapter 20 is affixed to a foot and ankle portion 14.
- Foot and ankle portion 14 comprises an ankle 22 pivotally affixed to foot 24 such that tube adapter 20 is affixed to a top of ankle 22.
- Foot shell 16 is received over foot and ankle portion 14 for cosmetic purposes.
- Foot shell 16 is generally shaped like a human foot and is molded from a flesh colored resilient material.
- Foot shell 16 has at an upper portion thereof a foot opening 28 for receiving the foot and ankle portion 14 therein.
- Foot shell 16 terminates at a top portion at an upper rim 30, which forms an upper peripheral lip 32 extending inwardly into foot opening 28.
- Foot opening 28 must be of sufficient size to receive therein foot and ankle portion 14 and thus when foot shell 16 is completely received over foot and ankle portion 14, foot opening 28 remains larger than leg portion 12 extending therethrough, and as here shown, specifically tube adapter 20.
- Such an arrangement permits the infusion of dirt, sand, and other contaminants, which are harmful to the functioning of foot and ankle portion 14.
- Foot gasket 40 comprises a peripheral body 42 whose outer perimeter generally conforms to the shape of foot shell 16 at upper rim 30.
- Body 42 defines a central opening 46 for receiving leg portion 12 therein.
- a lip 48 extends from the bottom of body 42 and in combination with body 42 defines a groove 50, which extends around the periphery of body 42.
- Groove 50 is sized to receive therein lip 32 of foot shell 16 to seal gasket 40 with foot shell 16.
- Foot shell 16 has an upper surface 44 that has a seal 52 attached thereto.
- seal 52 comprises a hollow boot 54 surrounding the lower part of leg portion 12 and extending upward where seal 52 is terminated with seal ring 56.
- Hollow boot 54 and upper surface 44 form a shoulder 45 which can interface with a cosmetic leg cover.
- Seal ring 56 is sized to closely receive endoskeletal tube 18 therein, thus completing gasket 40 and sealing the interior of foot shell 16 so that contaminants do not enter and impair the function of foot and ankle portion 14.
- Gasket 40 is constructed of a resilient material, which is resiliently deformable so that the gasket 40 can easily be installed and maneuvered to receive lip 32 in groove 50.
- FIG 4 shows alternative embodiment gasket 60 wherein gasket 60 comprises a body 62 constructed similarly to body 42 in the previous embodiment such that gasket 60 affixes to foot shell 16 in a like manner.
- Gasket 60 defines a central opening 66 for receiving leg portion 12 therein and terminates at top surface 64.
- Adhesive layer 68 forms the seal between gasket 60 and a lower end of cosmetic leg cover 34.
