Resistance type exercise device
First Claim
1. 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.

Abstract
The present invention relates to a resistance type exercise device that uses frictional forces between members to provide resistance for a variety of different exercises. In operation, when a pull cord is withdrawn from the exercise device, a cord wheel converts the translational movement to rotational motion. A brake lever contacting a brake drum fixedly attached to the cord wheel provides a friction resistive force to the rotational motion. A recoil cord causes the recoil cord 900 to stretch and wrap around a bearing lug, placing the recoil cord in tension. The potential energy stored in the tensioned recoil cord is used to rewind the cord wheel and restore the pull cord back to its at rest position.
