  • Patent number: 8984849
    Abstract: A stirrup includes a stirrup leather opening and a foot opening. Above the stirrup leather opening is a top member that includes a number of bends. A first bend is in a first direction, a second bend is in a second direction, opposite to the first direction, a third bend is a first direction, and a fourth bend is in the second direction. The bends in the top member will orient the stirrup iron at an angle relative to the horse, rather than parallel to the side of a horse as in a typical straight or flat stirrup. The stirrup is more stable, reduces pain and stress in the leg, is easier to retrieve, and is safer than conventional stirrups.

  • Patent number: 5794419
    Abstract: An equestrian stirrup iron that swivels with respect to the stirrup leather so that in preparation for riding, the rider may bring the stirrup iron down from the run up position, pivot it to a desired angle in the generally forward direction, and insert his or her foot therein. A cylindrical swivel base is fastened to the top of the arch of the swivel iron. A cylindrical swivel body is rotatably mounted to the swivel base. A member having a stirrup leather opening is attached to the swivel body. The swivel body may be rotatably secured to the swivel base by a threaded fastener or by a welded shank or pin. A spring-loaded ball in the swivel base cooperates with a plurality of detent cones disposed in the swivel body. In another version, a spring-loaded friction member disposed in the swivel base cooperates with a friction disk mounted on the lower surface of the swivel body to provide smoothly variable angular increments of rotation.
