FIELD OF THE INVENTION
The present invention relates generally to an exercise machine. More specifically, the present invention is a multifunctional exercise machine that combines the functionality of a stepping machine and a stationary bicycle.
BACKGROUND OF THE INVENTION
Stepping machines and stationary bicycles are often favored for exercise due to their safety and effectiveness in improving cardiovascular endurance as well as lower body muscle strength. Stepping machines and stationary bicycles are effective for low impact exercise due to the fact that the feet remain in contact with the steps and the pedals respectively when performing exercise. This results in less stress on the joints, muscles, and tendons. Additionally, the user's movement during exercise on a stepping machine or a stationary bicycle is fluid and continuous rather than sporadic. Stepping machines and stationary bicycles are often utilized for physical therapy and rehabilitation due to the low impact exercise provided. Stepping machines and stationary bicycles typically include a mechanism for adjusting the intensity of a workout by increasing or decreasing the resistance experienced by the user when stepping or cycling.
The present invention is a multifunctional exercise machine that combines the functionality of a stepping machine and a stationary bicycle. As such, the present invention provides the user with multiple low impact exercise options for improving cardiovascular endurance and lower body muscle strength.

DETAIL DESCRIPTIONS OF THE INVENTION
All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.
The present invention is a multifunctional exercise machine that provides the user with the functionality of both a stepping machine and a stationary bicycle. The present invention is shown in FIGS. 1-4 and comprises a stepper assembly 1, a stationary bicycle assembly 4, a stepper resetting mechanism 9, a frame member 14, a stand member 18, and a bridge 19.
The stepper assembly 1 functions similarly to a stepping machine that is utilized to improve cardiovascular endurance as well as lower body muscle strength. The stepper assembly 1 comprises a first step pedal 2 and a second step pedal 3. The user's feet are placed into contact with the first step pedal 2 and the second step pedal 3 during use of the stepper assembly 1. For user safety, the first step pedal 2 and the second step pedal 3 may be covered with a rubberized coating in order to minimize slippage. The frame member 14 serves as a base for the stepper assembly 1. The first step pedal 2 and the second step pedal 3 are slidably mounted along the frame member 14, allowing the first step pedal 2 and the second step pedal 3 to slide along the frame member 14 when the user applies force with his or her feet. Additionally, the first step pedal 2 and the second step pedal 3 are positioned opposite to each other about the frame member 14. The first step pedal 2 and the second step pedal 3 are thus separated by a sufficient distance such that the user may comfortably exercise utilizing the stepper assembly 1. The stepper resetting mechanism 9 enables the first step pedal 2 and the second step pedal 3 to slide relative to each other along the frame member 14. The stepper resetting mechanism 9 is operatively connected in between the stepper assembly 1 and the frame member 14, securing the stepper resetting mechanism 9 to the frame member 14 and allowing the stepper resetting mechanism 9 to regulate the movement of the first step pedal 2 and the second step pedal 3. In the preferred embodiment of the present invention, the stepper resetting mechanism 9 returns the first step pedal 2 and the second step pedal 3 from an actuated position to an equilibrium position. This enables the first step pedal 2 and the second step pedal 3 to slide in opposite directions relative to each other along the frame member 14.
The stand member 18 serves as a base for the stationary bicycle assembly 4. The bridge 19 serves as a connecting point in between the frame member 14 and the stand member 18. The frame member 14 is hingedly and adjacently connected to the bridge 19. The stand member 18 is hingedly and adjacently connected to the bridge 19 as well, opposite to the frame member 14. This enables the present invention to be folded into a compact configuration for convenient storage.
The stationary bicycle assembly 4 functions similarly to a bicycle and simulates the action of riding a bicycle while remaining in a stationary position. The stationary bicycle assembly 4 is mounted along the stand member 18 and is thus positioned away from the stepper assembly 1.
With continued reference to FIGS. 1-4, the frame member 14 comprises a first rail 15 and a second rail 16. The first rail 15 and the second rail 16 enable the first step pedal 2 and the second step pedal 3 to slide along the frame member 14. The first rail 15 and the second rail 16 are positioned adjacent to each other in order to enable the first step pedal 2 and the second step pedal 3 to move side-by-side. The first step pedal 2 is slidably engaged to the first rail 15 while the second step pedal 3 is slidably engaged to the second rail 16. The first step pedal 2 and the second step pedal 3 are thus able to slide along the first rail 15 and the second rail 16, respectively, under influence of the stepper resetting mechanism 9. In the preferred embodiment of the present invention, the stepper resetting mechanism 9 comprises a pulley 10 and a chain 11 that are utilized to move the first step pedal 2 and the second step pedal 3 in opposite directions relative to each other along the frame member 14 during use of the stepper assembly 1. As shown in FIG. 3, a first end 12 of the chain 11 is tethered to the first step pedal 2 while a second end 13 of the chain 11 is tethered to the second step pedal 3. The chain 11 is thus able to pull and direct the movement of the first step pedal 2 and the second step pedal 3 along the first rail 15 and the second rail 16. The pulley 10 is rotatably mounted to the first rail 15 and the second rail 16 while the chain 11 is tensionably engaged about the pulley 10. As a result, the sliding motion of the first step pedal 2 and the second step pedal 3 on the first rail 15 and the second rail 16 allows the chain 11 to rotate the pulley 10, ensuring that the first step pedal 2 and the second step pedal 3 slide in opposite directions relative to each other on the first rail 15 and the second rail 16. The pulley 10 is positioned adjacent to the bridge 19 and is thus offset from the stepper assembly 1 on the frame member 14.
Alternative embodiments of the present invention may utilize various additional types of mechanisms for the stepper resetting mechanism 9. One such example is a hydraulic cylinder mechanism featuring two hydraulic cylinders that serve to return the first step pedal 2 and the second step pedal 3 from an actuated position to an equilibrium position when the hydraulic cylinders are actuated. The hydraulic cylinders may be connected to the frame member 14 in a manner such that the present invention may still be folded into a compact configuration.
With continued reference to FIGS. 1-4, in various embodiments of the present invention, the first step pedal 2 and the second step pedal 3 may be removable from the first rail 15 and the second rail 16. As such, the present invention further comprises a first detachable carriage 20 and a second detachable carriage 21 that enable the first step pedal 2 and the second step pedal 3 to be removed from the frame member 14 as needed. The user may wish to remove the first step pedal 2 and the second step pedal 3 in order to ensure that the first step pedal 2 and the second step pedal 3 do not obstruct the user's legs during use of the stationary bicycle assembly 4. The first step pedal 2 is slidably mounted to the first rail 15 by the first detachable carriage 20 while the second step pedal 3 is slidably mounted to the second rail 16 by the second detachable carriage 21. The first detachable carriage 20 and the second detachable carriage 21 are thus able to slide along the first rail 15 and the second rail 16 along when the user applies force to the first step pedal 2 and the second step pedal 3.
In the preferred embodiment of the present invention, the first rail 15 and the second rail 16 are curved and each comprise a concave portion 17. The curved design of the first rail 15 and the second rail 16 provides a beneficial effect to the unique range of motion experienced by the user during use of the stepper assembly 1. The concave portion 17 is oriented toward the frame member 14 in order to provide an alternative range of motion during exercise compared to the range of motion provided by a straight design.
The present invention further comprises a chain braking system 22 that is utilized to adjust the difficulty of exercising utilizing the stepper assembly 1. The chain braking system 22 is mechanically integrated between the frame member 14 and the stepper resetting mechanism 9. As such, the chain braking system 22 is able to adjust the resistance of the stepper resetting mechanism 9 to the movement of the first step pedal 2 and the second step pedal 3 on the first rail 15 and the second rail 16 while the user is exercising. The chain 11 is operatively integrated through the chain braking system 22, allowing the chain braking system 22 to increase or decrease angular speed of the chain 11 about the pulley 10. This in turn increases or decreases the difficulty of exercise utilizing the stepper assembly 1.
The stationary bicycle assembly 4 comprises a flywheel assembly 5, a first cycle pedal 6, and a second cycle pedal 7. When the user is exercising on the stationary bicycle assembly 4, the first cycle pedal 6 and the second cycle pedal 7 are rotated, causing the flywheel assembly 5 to spin and build momentum. As with the first step pedal 2 and the second step pedal 3, the first cycle pedal 6 and the first cycle pedal 6 may be covered with a rubberized coating to minimize slippage. The flywheel assembly 5 additionally provides constant resistance to the stationary bicycle assembly 4. The resistance of the stationary bicycle assembly 4 may be adjusted in order to increase or decrease the difficulty of exercising utilizing the stationary bicycle assembly 4. The flywheel assembly 5 is mounted along the stand member 18 and is thus positioned away from the stepper assembly 1 positioned on the frame member 14. The first cycle pedal 6 and the second cycle pedal 7 are torsionally connected into the flywheel assembly 5, allowing the first cycle pedal 6 and the second cycle pedal 7 to spin the flywheel assembly 5. As shown in FIG. 4, a rotation axis 8 of the first cycle pedal 6 and a rotation axis 8 of the second cycle pedal 7 are oriented perpendicular to the stand member 18. The stationary bicycle assembly 4 may thus be utilized to exercise in a similar manner to a conventional standalone stationary bicycle.
The present invention may further comprise an adjustable seat 23. The adjustable seat 23 is mounted into the bridge 19 and is thus positioned in between the stepper assembly 1 and the stationary bicycle assembly 4. The adjustable seat 23 may be locked in place via a pin lock. The adjustable seat 23 may be positioned within the bridge 19 in a manner such that the leg room is increased when utilizing the present invention.
The present invention may further comprise a seat adjustment member 24. In the embodiment of the present invention shown in FIGS. 1-4, the seat adjustment member 24 is utilized to rotate the adjustable seat 23 to face the stepper assembly 1 or the stationary bicycle assembly 4. In this embodiment of the present invention, the seat adjustment member 24 is rotatably engaged into the bridge 19, enabling the adjustable seat 23 to be rotated to face the stepper assembly 1 or the stationary bicycle assembly 4. The seat adjustment member 24 may then be locked into place. In the embodiment of the present invention shown in FIG. 5, the seat adjustment member 24 is utilized to adjust the height of the adjustable seat 23 relative to the bridge 19. In this embodiment of the present invention, the seat adjustment member 24 is adjacently connected to the adjustable seat 23 and as such may be utilized to increase or decrease the height of the adjustable seat 23. The seat adjustment member 24 is slidably engaged into the bridge 19. The seat adjustment member 24 may thus be inserted into or drawn out of the bridge 19 in order to adjust the height of the adjustable seat 23. After the adjustable seat 23 is at the desired height, the seat adjustment member 24 may be locked into place.
In various embodiments of the present invention, the stationary bicycle assembly 4 may be removable from the stand member 18. The present invention further comprises at least one mounting bracket 25 for use in holding the stationary bicycle assembly 4. The at least one mounting bracket 25 is positioned on the stand member 18, enabling the stationary bicycle to be fastened to the stand member 18 utilizing the at least one mounting bracket 25. The stationary bicycle assembly 4 is removably mounted to the stand member 18 by the at least one mounting bracket 25, allowing the user to remove the stationary bicycle assembly 4 from the stand member 18 altogether. The user may wish to separate the stationary bicycle assembly 4 from the stand member 18 in order to ensure that the stationary bicycle assembly 4 does not obstruct the user's movement during use of the stepper assembly 1.
While the present invention may be utilized hands-free, the present invention may further comprise a handlebar assembly 26 to improve user stability while exercising. The handlebar assembly 26 is mounted into the bridge 19 and may be grasped by the user while exercising to stabilize his or her body.
As shown in FIG. 6 and FIG. 7, the present invention may additionally include an electronic monitoring device that is utilized to track various statistics such as total workout time, number of steps taken, and calories burned. The electronic monitoring device may be battery-operated or connected to an external electrical source such as a wall outlet. The electronic monitoring device may be mounted facing toward the stepper assembly 1 or facing toward the stationary bicycle assembly 4. Additionally, the electronic monitoring device may be mounted in a manner such that the orientation of the electronic monitoring device may be changed.
Although the present invention has been explained in relation to its preferred embodiment, it is understood that many other possible modifications and variations can be made without departing from the spirit and scope of the present invention as hereinafter claimed.
