## Background
RELATED APPLICATIONS
This application claims priority to Provisional Patent Application No. 61/069,695 filed Mar. 17, 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 consists of 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, and a leg extension/leg curl station in front of the user seating. 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. 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 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 which allows the user to perform leg extension and leg curl exercises without interference from the wrist rolling assembly. The wrist rolling assembly can be adjusted to a second position wherein wrist rolling exercises can be performed. The exercise apparatus comprises a frame, a resistance element, and in one exemplary embodiment, a leg exercise arm assembly and a wrist rolling assembly pivotally attached to the frame wherein a flexible connecting line and pulley system connects the leg exercise arm assembly and wrist rolling assembly to the resistance element.
In another aspect of the invention, a single flexible line within the flexible line connecting system interconnects the leg exercise arm assembly and the wrist rolling assembly with the resistance element wherein a substantially constant tension is maintained on the flexible line connecting system whether the wrist rolling assembly is in a first storage position or a second in use position.
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, a single flexible line within the flexible line connecting system interconnects the leg exercise arm assembly and the wrist rolling assembly with the resistance element wherein a substantially constant tension is maintained on the flexible line connecting system whether the wrist rolling assembly is in a first storage position or a second in use position.
Other aspects of the invention will become apparent in the detailed description.

The user would then curl their leg back and forth for the desired number of repetitions. The wrist roller assembly 150 in this locked first position in storage does not interfere with the user's legs or feet during leg curl exercises. The user could lock wrist roller 150 into a second position as shown in FIG. 2 and use the wrist roller as a brace to help stabilize the body while performing leg curl exercises. The wrist roller assembly 150 in this locked second position would not interfere with the user's legs or feet during leg curl exercises.
FIG. 2 illustrates exercise apparatus 10 wherein the wrist roller assembly 150 is in a locked second position in use. FIGS. 7 and 8 also illustrate the user support assembly 90, the leg exercise arm assembly 130, and the wrist roller assembly 150 wherein the wrist roller assembly 150 is locked into the seat main frame 95 into a second position in use. To perform wrist rolling exercise, the user would select the desired amount of resistance from weight stack 30. The user could sit on user support assembly 90 and be in a seated position to perform wrist rolling exercise or the user could straddle user support assembly 90 or stand in front of user support assembly 90 to perform wrist rolling exercise. Once the seated or standing position is selected, the user would then grasp grips 164 on handle bars 163 and then begin to roll their wrists forwards or backwards, thus rotating the flexible line reel 160 wherein a flexible line within flexible line connecting system 200 will wrap around flexible line reel 160 and displace weight stack 30. Once finished performing wrist rolling exercises, the user can unlock locking pin 155 of wrist roller assembly 150 and pivot wrist roller assembly 150 downward and lock it into the above described first position in storage wherein locking pin 141 of leg exercise arm assembly 130 secures wrist roller assembly 150 to the leg exercise arm assembly 130. When locked into the first position in storage, the wrist roller assembly 150 will not interfere with any other exercise movements or positions of the user on exercise apparatus 10.

The flexible line routing is illustrated for both locked positions. The illustration of the flexible line routing wherein the wrist roller assembly 150 is locked into a first position in storage begins near the bottom of leg exercise arm assembly 130 with pulley 201 and is labeled with the letter A. The flexible line then travels upward and partially wraps over pulley 202. The flexible line then travels upward and partially wraps under pulley 203. The flexible line then travels upward and wraps over pulley 204 and then back downward and connects to wrist roller assembly 150.
The illustration of the flexible line routing wherein the wrist roller assembly 150 is locked into a second position in use begins near the bottom of leg exercise arm assembly 130 with pulley 201 and is labeled with the letter B. The flexible line then travels upward and partially wraps over pulley 202. The flexible line then travels upward and partially wraps under pulley 203. The flexible line continues to travel upward and connects to wrist roller assembly 150.
The portion of flexible line A that wraps partially around the circumference of pulley 204 when the wrist roller assembly 150 is locked in the first position in storage is equal to the offset height differential of the wrist roller assembly 150 pivot axis from pulley 204. Therefore, because flexible line B bypasses pulley 204 and is connected directly into wrist roller assembly 150 when the wrist roller assembly 150 is locked in the second position in use, the length of flexible line A is equal to the length of flexible line B. Since the portion of the flexible line interconnecting the leg exercise arm assembly 130 with the wrist roller assembly 150 maintains a substantially equal length whether the wrist roller assembly 150 is locked into a first position in storage or locked into a second position in use, the flexible line connecting system 200 will also maintain a substantially constant tension whether the wrist roller assembly 150 is locked into a first position in storage or locked into a second position in use.

The illustration of the flexible line routing wherein the wrist roller assembly 250 is locked into a first position in storage begins near the bottom of leg exercise arm assembly 230 with pulley 201 and is labeled with the letter C. The flexible line then travels upward and partially wraps over pulley 202. The flexible line then travels upward and partially wraps under pulley 203. The flexible line then travels upward and wraps over pulley 204 and then back downward and connects to wrist roller assembly 250.
The illustration of the flexible line routing wherein the wrist roller assembly 250 is locked into a second position in use begins near the bottom of leg exercise arm assembly 230 with pulley 201 and is labeled with the letter D. The flexible line then travels upward and partially wraps over pulley 202. The flexible line then travels upward and partially wraps under pulley 203. The flexible line continues to travel upward and connects to wrist roller assembly 250.
The portion of flexible line C that wraps partially around the circumference of pulley 204 when the wrist roller assembly 250 is locked in the first position in storage is equal to the offset height differential of the wrist roller assembly 250 pivot axis from pulley 204. Therefore, because flexible line D bypasses pulley 204 and is connected directly into wrist roller assembly 250 when the wrist roller assembly 250 is locked in the second position in use, the length of flexible line C is equal to the length of flexible line D. Since the portion of the flexible line interconnecting the leg exercise arm assembly 230 with the wrist roller assembly 250 maintains a substantially equal length whether the wrist roller assembly 250 is locked into a first position in storage or locked into a second position in use, the flexible line connecting system 200 will also maintain a substantially constant tension whether the wrist roller assembly 250 is locked into a first position in storage or locked into a second position in use.

In this alternate embodiment, the leg exercise arm assembly 330 is pivotally attached to the user support assembly 90 and the wrist roller assembly 350 is pivotally attached to the leg exercise arm assembly 330, therefore the wrist roller assembly 350 moves along with leg exercise arm assembly 330 during leg curl exercises. To perform leg curl exercise, the user would select the desired amount of resistance from weight stack 30, stand in front facing user seat support 90, adjust the upper pad assembly 125 wherein the pads are above the pivot axis of leg exercise arm assembly 330, brace the front of one of their legs just above their knee against upper pad assembly 125, and brace the same leg near their ankle behind a respective lower pad 135 of leg exercise arm assembly 330. The user would then curl their leg back and forth for the desired number of repetitions. The wrist roller assembly 350 in this locked first position in storage does not interfere with the user's legs or feet during leg curl exercises.
FIGS. 25 and 26 illustrate user support assembly 90 wherein the wrist roller assembly 350 is in a locked second position in use. To perform wrist rolling exercise, the user would select the desired amount of resistance from weight stack 30. The user could sit on user support assembly 90 and be in a seated position to perform wrist rolling exercise or the user could straddle user support assembly 90 or stand in front of user support assembly 90 to perform wrist rolling exercise. Once the seated or standing position is selected, the user would then grasp grips 164 on handle bars 163 and then begin to roll their wrists forwards or backwards, thus rotating the flexible line reel 160 wherein a flexible line within flexible line connecting system 200 will wrap around flexible line reel 160 and displace weight stack 30. Once finished performing wrist rolling exercises, the user can unlock locking pin 234 of leg exercise arm assembly 330 and pivot wrist roller assembly 350 downward and lock it into the above described first position in storage wherein locking pin 234 of leg exercise arm assembly 330 secures wrist roller assembly 350 to the leg exercise arm assembly 330. When locked into the first position in storage, the wrist roller assembly 150 will not interfere with any other exercise movements or positions of the user on exercise apparatus 10.
FIG. 27 illustrates a wrist roller assembly 350 pivotally attached to a leg exercise arm assembly 330 and locked into a first position in storage, a wrist roller assembly 350 pivotally attached to a leg exercise arm assembly 330 and locked into a second position in use, and a wrist roller assembly 350 in a position along the adjustment path between the first locked position and the second locked position. The flexible line routing is illustrated for both locked positions as well as a position along the adjustment path between the first locked position and the second locked position. The illustration of the flexible line routing wherein the wrist roller assembly 350 is locked into a first position in storage begins near the bottom of leg exercise arm assembly 330 with pulley 201 and is labeled with the letter E. The flexible line then travels upward and partially wraps over pulley 202. The flexible line then travels upward and partially wraps under pulley 203. The flexible line then travels upward and wraps over pulley 204, which is attached to wrist roller assembly 350, and then back downward and connects to wrist roller assembly 350.
The illustration of the flexible line routing wherein the wrist roller assembly 350 is locked into a second position in use begins near the bottom of leg exercise arm assembly 330 with pulley 201 and is labeled with the letter G. The flexible line then travels upward and partially wraps over pulley 202. The flexible line then travels upward and partially wraps under pulley 203. The flexible line continues to travel upward and connects to wrist roller assembly 350.
The portion of flexible line E that wraps partially around the circumference of pulley 204 when the wrist roller assembly 350 is locked in the first position in storage is equal to the offset height differential of the wrist roller assembly 350 pivot axis from pulley 204. Therefore, because flexible line G bypasses pulley 204 and is connected directly into wrist roller assembly 350 when the wrist roller assembly 350 is locked in the second position in use, the length of flexible line E is equal to the length of flexible line G. Since the portion of the flexible line interconnecting the leg exercise arm assembly 330 with the wrist roller assembly 350 maintains a substantially equal length whether the wrist roller assembly 350 is locked into a first position in storage or locked into a second position in use, the flexible line connecting system 200 will also maintain a substantially constant tension whether the wrist roller assembly 350 is locked into a first position in storage or locked into a second position in use.
The illustration of the flexible line routing wherein the wrist roller assembly 350 is in a position along the adjustment path between the first locked position and the second locked position begins near the bottom of leg exercise arm assembly 330 with pulley 201 and is labeled with the letter F. The flexible line then travels upward and partially wraps over pulley 202. The flexible line then travels upward and partially wraps under pulley 203. The flexible line continues to travel upward and wraps partially over the circumference of pulley 204, which is attached to wrist roller assembly 350, and then connects to wrist roller assembly 350. Since pulley 204 is attached to the wrist roller assembly 350, the offset height differential of the wrist roller assembly 350 pivot axis from pulley 204 and portion of flexible line F that wraps partially around the circumference of pulley 204 will constantly change and offset one another when the wrist roller assembly 350 pivots from one locked position to another. Therefore, the portion of the flexible line interconnecting the leg exercise arm assembly 330 with the wrist roller assembly 350 will maintain a substantially equal length whether the wrist roller assembly 350 is locked into a first position in storage, locked into a second position in use, or any position in between. Therefore, the flexible line connecting system 200 will also maintain a substantially constant tension whether the wrist roller assembly 350 is locked into a first position in storage, locked into a second position in use, or being pivotally adjusted from one locked position to another.
