  • Publication number: 20260021346
    Abstract: A reformer exercise apparatus includes a frame having one or more rails spaced between a head end and a foot end of the frame, a carriage supported on the one or more rails for reciprocal movement of the carriage between the head end and the foot end of the frame, and an inverted U shaped foot bar carried by the one or more rails and selectively positionable near the foot end of the frame. The apparatus has an electrical motor and controller assembly fastened to the carriage that drives a cord member removably coupled from the motor on the carriage to an anchor fastened to the foot end of the frame. This motor is operable to continuously bias the cord member on the carriage toward the foot end of the frame. The motor and controller assembly alternately form a retrofit kit for replacement of springs on a conventional reformer.

  • Patent number: 11198030
    Abstract: An exercise apparatus includes a base configured to rest on a horizontal floor surface. A vertical pole member is fastened to the base and extends vertically from the floor surface. A cross bar sleeve is fastened to an upper end portion of the vertical pole member and supports a pair of cross bar members extending in opposite directions. One or more elastic resistance members extends from the cross bar members. A rectangular foot support plate is removably supported on the base. This rectangular foot support plate has a pair of spaced apart lugs projecting from an underside surface of the foot support plate along one edge. Each is adapted to fit within one of a plurality of recesses in the base so as to incline the foot support plate at an angle with respect to the base when the foot support plate is supported on the base.

  • Patent number: 10973324
    Abstract: A frame corner member includes an elongated hollow extrusion having a central corner portion and two leg portions extending from the central portion. Each leg portion includes an inner side wall spaced from and parallel to an outer side wall, and merging with the central portion. An outer end wall joins the inner and outer side walls, which each include an inner surface facing the inner surface of the other side wall. An opening through the outer end wall defines a space between the inner and outer side walls adjacent one end of the extrusion for receiving one end of one of frame side members and end members. At least one of the inner surfaces in the space has discrete surface features adapted to grip and retain the one end of one of the side members and end members in the space when received through the opening.
