Brief Patent Description - Full Patent Description - Patent Application Claims
CROSS-REFERENCE TO RELATED APPLICATION [0001]The present application is based on and claims the benefit of U.S. provisional patent application Ser. No. 60/825,209, filed Sep. 11, 2006, the content of which is hereby incorporated by reference in its entirety. BACKGROUND [0002]Core muscles of a human body include abdominal muscles, pelvic muscles and lower back muscles. Basically, a core muscle is any muscle located between the pelvis and the base of the ribcage. Core muscles are able to work together to support the spine. When a person strengthens their core muscles, a gain in balance and stability are realized. [0003]Currently there are a wide-variety of exercises available to exercise core muscles. Some such exercises include conventional weightlifting using free weights, weight machines, bar bells and exercise "bands." The free weights and barbells of a conventional construction include weighted ends and a hand held bar in the center. Oftentimes weight machines use pulley structures and hydraulic or pneumatic cylinders to aid a user in lifting weights in various positions. These machines also provide variable resistance to the user. Such exercise equipment can be intimidating to a novice and can also exert excessive stress or strain on the body, especially where the user does not have a great deal of experience in the particular type of weight training or weightlifting being used. [0004]One type of exercising device includes a stack of weighted plates connected to a pulley structure and a connecting seat. An individual sits in the seat of the exercising device and pulls on the straps connected to the pulley structures as they bend at the waist. This type of machine exercises abdominal muscles. Although this exercising device is beneficial to the body, there are many disadvantages. In particular, this large piece of equipment is only designed to exercise one particular group of muscles in the abdomen. Furthermore, undue strain can be exerted on the spine. [0005]Many exercises for exercising core muscles can also be performed without the use of weights or weighted machines. For example, stomach crunches can be performed while on the ground in a laying position. However, some users have difficulty getting into a laying down position to perform these stomach crunches. [0006]The discussion above is merely provided for general background information and is not intended to be used as an aid in determining the scope of the claimed subject matter. SUMMARY [0007]This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. The claimed subject matter is not limited to implementations that solve any or all disadvantages noted in the background. [0008]An exercise device includes a base frame and a carriage. The base frame includes at least one curved track having a first end and a second end. The second end is elevated above the first end. The carriage is moveable between the first end and the second end of the curved track. The carriage includes a support frame having an axis of rotation, an upper body frame coupled to the support frame and rotatable about the axis of rotation and a resistance mechanism coupled to the upper body frame to resist pivoting of the upper body frame about the axis of rotation. [0009]Many variations of exercises can be performed with the exercise device as described. Exercises can be performed that incorporate simultaneous use of the at least one curved track with rotation of the upper body frame about the axis of rotation. However, other exercises can be performed that incorporate just the rotation of the upper body frame about the axis of rotation or just the movement along the at least one curved track. BRIEF DESCRIPTION OF THE DRAWINGS [0010]FIG. 1 illustrates a front perspective view of an exercise device under one embodiment. [0011]FIG. 2 illustrates back perspective view of the exercise device of FIG. 1. [0012]FIG. 3 illustrates a partial enlarged view of a resistance mechanism under one embodiment. [0013]FIG. 4 illustrates a side view of the exercise device illustrated in FIG. 1. [0014]FIG. 5 illustrates a side view of the exercise device of FIG. 1 including a use at a first elevation. [0015]FIG. 6 illustrates a side view of the exercise device of FIG. 1 at a second elevation. [0016]FIG. 7 illustrates a front perspective view of an exercise device under one embodiment. [0017]FIG. 8 illustrates a perspective view of the exercise device of FIG. 7 in a stored position. [0018]FIG. 9 illustrates a front perspective view of an exercise device under one embodiment. DETAILED DESCRIPTION [0019]FIG. 1 illustrates a front perspective view of an exercise device 100 under one embodiment. Exercise device 100 includes a base frame 102 and a carriage 104. Base frame 102 includes a pair of curved tracks 106, a support leg 108 and a foot rest 109. Although exercise device 100 includes a pair of curved tracks 106, exercise device 100 can have any number of tracks including a single track. Curved tracks 106 include first ends 110 and second ends 112. First ends 110 are proximate to the ground or in contact with the ground, while second ends 112 are elevated above first ends 110 by support leg 108. First ends 110 are also coupled to foot rest 109, which is oriented at an angle from curved tracks 106. Curved tracks 106 extend from first ends 110 to second ends 112 along a radius of curvature. Although curved tracks 106 are illustrated as rails having a rectangular cross-section, curved tracks can have any type of geometrical shaped cross-section.
