Abstract
A walking iron for attachment to the lower extremity of a foot or leg cast which bottom supports the limb and enables mobility of an injured person. The walking iron has a fixed, cast-engaging member adjustably connected to a ground-engaging member in such a manner that pivotal and longitudinal movement may be effected therebetween, thereby enabling lateral as well as fore and aft movement of one member respective to the other to be achieved. This expedient provides for center of gravity adjustment between the two members so that the walking iron can be specially fitted to each individual cast in the most optimum manner for each patient.
Claims7
A walking iron for use in conjunction with a cast applied to one's lower extremity, such as ones foot, comprising:
- a cast-engaging fixed member;
- a ground-engaging member;
- said ground-engaging member includes a main body having opposed sides, a toe end, a heel end, a lowermost ground-engaging surface, and an uppermost end portion;
- said fixed member includes an upper and a lower face and which can be integrally incorporated into a cast applied to one's foot such that the upper surface of the fixed member can bottom support the lower end of a cast, thereby transferring a load from a limb, into the fixed member, and into the ground-engaging member;
- a web member affixed to the lower face of said fixed member which downwardly extends therefrom and terminates in a longitudinally extending enlargement;
- said longitudinally extending enlargement includes an axial centerline extending generally in a direction from said toe towards said heel;
- means forming a cavity within said ground-engaging member for slidably receiving said enlargement therewithin, so that said ground-engaging member can be pivotally moved respective to said fixed member;
- a gap formed within said uppermost end portion of said ground-engaging member by which said cavity upwardly opens;
- said web extends through said gap;
- and fastener means by which said fixed and ground-engaging members are rigidly fastened to one another.
A walking iron for incorporation into the lower extremity of a cast applied to one's foot, comprising:
- a cast-engaging fixed member and a ground-engaging adjustable member;
- said fixed and adjustable members are connected together by an adjustment means which allows pivotal movement in a lateral direction therebetween;
- said fixed member includes an upper platform member which can be integrally affixed to the lower extremity of a cast, a web member having one end affixed to and downwardly extending from said platform, the opposed end of said web member is affixed to an elongated enlargement;
- said adjustable member includes a ground-engaging lower end and an upper end pivotally connected to said enlargement by said adjustment means;
- said adjustment means includes an elongated counterbore formed in said adjustable member and made complementary respective to said enlargement, so that said enlargement is slidably received in a pivotal manner within said counterbore;
- and fastener means by which said adjustable member is fixed respective to said fixed member.
