RELATED APPLICATIONS
This application claims priority to Provisional Patent Application No. 61/070,536 filed Mar. 24, 2008, which is incorporated herein by reference.


FIELD OF THE INVENTION
The present invention is directed generally to exercise equipment and, more particularly, an apparatus to perform leg exercises and wrist rolling exercises.
BACKGROUND
Various types of exercise machines for strengthening and conditioning the body are known. One group of exercise machines are categorized as multi station gyms. Multi station gyms combine multiple exercise stations onto one frame, typically sharing one user support seat, in order to save space and cost. Also, most multi station gyms typically have one resistance source shared by all the stations to further save cost. The resistance source is usually a weight stack wherein a cable system interconnects all the exercise stations to the weight stack. Since all the exercise stations share the same frame and typically the same resistance source, the exercise stations will be close to one another and must cooperatively work with one another wherein the exercise movement of one station will not interfere with the movement of another exercise station. A properly designed multi station gym will also allow the user to properly position their self to perform each exercise without interference from any of the unused stations.
One common design of a multi station gym includes a user support bottom seat and back seat near the front of the gym and a weight stack near the back of the gym. This common design also includes a high pull station above the user support seating, a vertical pressing station just below the high pull station, a mid section free cable end to pull just above and behind the seating for performing abdominal crunches, a leg extension/leg curl station in front of the user seating, and a low section free cable end to pull which exits near the bottom of the leg extension/leg curl station. To use the high pull down station, the user pulls down one or two free cables to exercise the back, bicep, and triceps muscles. To use the pressing station, the user presses one or two arms outward to exercise the chest muscles. To use the mid section free cable, the user attaches an abdominal crunch strap to the free cable and performs abdominal crunches to exercise the abdominal muscles. To use the leg extension station, the user sits in the seat and puts their knees over an upper pad assembly and their ankles behind a lower pad assembly and performs extensions to exercise the thigh muscles. To use the leg curl station, the user adjusts the upper pad assembly above the leg extension/curl arm assembly pivot point in order to brace their leg just above their knee while facing the gym. The user then aligns their knee with the leg extension/curl arm assembly pivot point and places their ankle behind the lower pad assembly and performs standing leg curls to exercise the hamstring muscles. To use the low section free cable end, the user usually attaches a curl bar to perform bicep curls. The combined stations allow the user to exercise their chest, back, upper arms, abdominal muscles, and legs. However, this compact design does not include an effective way to isolate and exercise the forearm muscles.
A known type of exercise apparatus to effectively isolate and exercise the forearms is a wrist rolling apparatus. A wrist rolling apparatus typically has a handle bar attached to a frame wherein a flexible line is connected at one end to the handle bar and wherein the other end is connected to resistance. To exercise the forearm muscles, a user will grasp the handle bar and roll their wrist forward or backwards wherein the handle bar will rotate on the frame in order to wrap the flexible line around the handle bar which will displace the resistance element and provide resistance.
It would be desirable for a multi station gym design to include a wrist rolling assembly wherein a user could effectively isolate and exercise their forearms. It would also be desirable to add the wrist roller assembly by minimally changing the compact size of the gym and by sharing the existing frame. It would also be desirable to add the wrist roller assembly to the gym wherein the user's movement and position while exercising with one station would not interfere with the user's movement and position while exercising with another station. It would also be desirable to add the wrist rolling assembly without adding an additional cable to the permanent cable system which would add extra cable stretch and cable bounce, and negatively affect the performance of the exercise stations.
SUMMARY
The present invention is an exercise apparatus which includes a leg exercise assembly and a wrist rolling assembly. The leg exercise assembly and wrist rolling assembly cooperatively work in tandem wherein the wrist rolling assembly is locked into a first storage position onto the leg exercise assembly wherein the wrist roller assembly pivots along with the leg exercise assembly during leg extension and leg curl exercises. This allows the user to perform leg extension and leg curl exercises without interference from the wrist rolling assembly. The exercise apparatus comprises a frame, a resistance element, and in one exemplary embodiment, an arm assembly, a high pull station, a mid pull station, a low pull station, and a leg exercise arm assembly along with a wrist rolling assembly pivotally attached to the frame wherein a flexible connecting line and pulley system interconnects the leg exercise arm assembly, the arm assembly, the high pull station, the mid pull station, and the low pull station to the resistance element.
In another aspect of the invention, the wrist rolling assembly can be adjusted to a second position wherein the wrist rolling assembly works in tandem with the high pull station, the mid pull station, or the low pull station. A flexible line on the wrist rolling assembly can be connected to a free flexible line end within the high pull station, or a free flexible line end within the mid pull station, or a free flexible line end within the low pull station wherein wrist rolling exercises can be performed. The free flexible line ends may be interconnected with the resistance element wherein one free flexible line end provides an alternate ratio of resistance than another when pulled, thus allowing the user to connect the wrist roller flexible line to the free flexible line end with the desired ratio of resistance.
In an alternate embodiment, the leg exercise arm assembly is pivotally attached to the frame and the wrist rolling assembly is pivotally attached to the leg exercise arm assembly. As in the previous embodiment, the leg exercise assembly and wrist rolling assembly cooperatively work in tandem wherein the wrist rolling assembly is locked into a first storage position onto the leg exercise assembly wherein the wrist roller assembly pivots along with the leg exercise assembly during leg extension and leg curl exercises. This allows the user to perform leg extension and leg curl exercises without interference from the wrist rolling assembly.
In another alternate embodiment, a wrist roller assembly is pivotally attached to the frame and can be locked into a storage first position on the frame which allows the user to perform chest press, mid row, high pull, and mid pull exercises without interference from the wrist roller assembly. The wrist roller assembly can also be pivotally adjusted and locked into a storage second position on the frame which allows the user to perform leg extension and leg curl exercises without interference from the wrist roller assembly. The wrist roller assembly can also be pivotally adjusted and locked into a use third position wherein a flexible line on the wrist rolling assembly can be connected to a free flexible line end within the high pull station, or a free flexible line end within the mid pull station, or a free flexible line end within the low pull station wherein wrist rolling exercises can be performed.
Other aspects of the invention will become apparent in the detailed description.
