Foot abduction apparatus
View Patent ↗An improved foot abduction apparatus allowing movement in a horizontal and vertical plane. The embodiments allow a user to more easily manipulate the apparatus in one or both planes through the use of strategically placed pivot points. The device utilizes at least one rigid member attached to coupling devices which contain at least one pivot point. The specialized coupling devices may be selectively attached to shoe receiving member or plates which are well known in the art. Additionally the shoe receiving members are able to receive an improved shoe containing a sole member contained with a silicone boot.

the second rigid member pivotable in the first plane about the third pivot point of the second coupling device,
the first rigid member and the second rigid member are in parallel with one another.
4. The invention of claim 3 wherein:
the second coupling device comprises a first segment, a second segment and a third segment,
the first section comprises a means to attach the second plate to the second coupling device,
the second section comprises a means to attach the first rigid member to the second coupling device,
the third section comprises a means to attach the second rigid member to the second coupling device.
5. The invention of claim 4 wherein:
the first coupling device and the second coupling device are made from a thermoplastic,
the first coupling device and the second coupling device are made by the process of injection molding.
6. The invention of claim 4 wherein: the left shoe receiving member further comprising a left shoe adjustment mechanism, the left shoe adjustment mechanism for making angular adjustments, the right shoe receiving member further comprising a right shoe adjustment mechanism, the right shoe adjustment mechanism for making angular adjustments, an angle made between the right shoe receiving member and the left shoe receiving member, the angle capable of being maintained as the system is manipulated in the first plane and the second plane.
