Abstract:
A resistance exercise device comprising:a) a housing comprising a base housing, a top cover, and a hub shaft, the top cover covering the base housing to form an enclosure, the hub shaft joined to an inside surface of the base housing and oriented substantially perpendicular to the inside surface of the base housing so as to project towards the top cover; b) a pull cord capable of substantially translation movement upon receiving a pull force; c) a cord wheel rotatably mounted on the hub shaft in the housing, the cord wheel storing the pull cord in the retracted position, and converting the substantially translational movement of the pull cord to rotational motion; d) a brake drum rotatably mounted on the hub shaft in the housing, the brake drum being concentrically oriented with the cord wheel, the brake drum being capable of interfacing with and rotating with the cord wheel by means of an interface mechanism; e) a brake lever mounted to the housing, the break lever contacting the brake drum and providing frictional resistance to the rotation of the brake drum; f) a recoil mechanism attached between the cord wheel and housing for recoiling the pull cord on the cord wheel; the recoil mechanism comprising i) a plurality of recoil bearings, each recoil bearing being rotatably connected to a recoil bearing post, the recoil bearing post being jointed to the inside surface of the base housing and oriented substantially perpendicular to the inside surface of the base housing so as to project towards the top cover; and ii) a recoil cord having a first and second end, the recoil cord being constructed of a resilient material, the first end of the recoil cord being connected to the housing and the second end of the recoil cord being attached to the cord wheel.
