Pivoting Stepper Apparatus

Abstract

A Pivoting Stepper Apparatus comprising a Frame Structure Member, a Foot Engagement Member, and an optional Resistance Member. The Frame Structure Member is comprised basically of a Base Frame Member and a Guide Platform Member. The Foot Engagement Member is pivotally mounted to the Base Frame Member and mainly comprises two Foot Support Members pivotally coupled together by a lever assembly such that they move in reciprocating upward and downward motions. The lever assembly is a dual lever assembly which keeps the Foot Support Member in a relatively horizontal positon while moving upward and downward. The Foot Support Members operatively engage the Guide Platform Member, with the upward and downward movements of the Foot Support Members create the pivoting movement of the Foot Engagement Member, and vice versa. The optional Resistance Member provides resistance in the pivoting motion of the Foot Engagement Member, and thus also in the upward and downward movements of the Foot Support Members.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0025] Before explaining in detail the present invention, it is to be understood that the invention is not limited in its application to the details of construction or arrangement of parts illustrated in the accompanying drawings, since the invention is capable of other embodiments and of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description, and not limitation.

[0026] As best can be seen by references to the drawings, and in particular to FIGS. 1A-1D, the Pivoting Stepper Apparatus that forms the basis of the present invention is designated generally by the reference numeral 1, and includes a Frame Structure Member 10, a Foot Engagement Member 20, and optional Resistance Member 30. The Foot Engagement Member 20 is pivotally mounted to the Frame Structure Member 10 in such a manner that the Foot Engagement Member 20 may pivot in the side to side directions. The option Resistance Member 30 may be used to provide a resistance to the movements of the Foot Engagement Member.

[0027] As may be seen in FIGS. 2A-2C, the Frame Structure Member 10 may comprise a base frame member with Outer Support Members 11, Cross Support Members 12, and an Inner Support Member 13. As may be seen, the Outer Support Members 11 are located on each side of the apparatus, and extend from the front of the apparatus to the rear of the apparatus. The Cross Support Members 12 rigidly connects the Outer Support Members together. The Inner Support Member 13 is similar to the Outer Support Members 11 in that it also extends from the front to the rear of the apparatus, with the Cross Support Members 12 also being rigidly mounted to it. This creates a rigid base frame member. Also included in the Frame Structure Member 10 is a Guide Platform Member 15, which includes a relatively flat platform mounted to the base frame member at a predetermined angle. An optional Handle Member 15 may also be part of the Frame Structure Member.

[0028] FIGS. 3A-3C shows the Foot Engagement Member 20 of the Pivoting Stepper Apparatus. As shown, the Foot Engagement Member 20 includes two Foot Support Members 21. These Foot Support Members 21 are generally horizontal, and are sized to support the bottom feet part of a typical user. They are connected together using a Dual Lever Assembly 23. Dual Lever Assembly 23 is basically comprised of two levers, each pivotally mounted at its proximate center to a Lever Support Member 24, and pivotally mounted at their opposite ends to the Foot Support Members 21. The Dual Lever Assembly provides a reciprocating upward and downward motion in the Foot Support Members 21, while also allowing the Foot Support Members to maintain a substantially horizontal position. The Lever Support Member 24 of the Foot Engagement Member 30 pivotally mounts at its lower area to the Inner Support Member of the Frame Structure Member, so that the Foot Engaging Member 20 may pivot in the side to side directions. The Foot Engaging Member 20 also includes a Platform Engaging Member 22 connected to each Foot Support Member for engaging the Guide Platform Member of the Frame Structure Member. Foot Engagement Member 20 also has a Resistance Connector Member 25 for connecting to the Resistance Member 30, when once is utilized.

[0029] FIGS. 4A-4C shows an optional Resistance Member 30, which may also be part of the Pivoting Stepper Apparatus. The Resistance Member 30 includes a Resistance Rotatable Member 31, a Closed Loop Connection Member 32, a flywheel 33, and a Resistance Generator Member 34. The Resistance Member 30 thus demonstrates a convention type of chain, sprocket, flywheel, and resistance device assembly which is commonly used on fitness products. The Resistance Member 30 shown connects to the Foot Engagement Member through its Resistance Connector Member. FIG. 4D demonstrates a Resistance Member 30 shows a different type of resistance concept which utilizes conventional Resistance Cylinders 35, as is also commonly found in many fitness products. In this instance, the Resistance Cylinders 34 are pivotally mounted at one end to the base frame structure, and pivotally mounted at their other ends to the Resistance Connector Member 25 of the Foot Engagement Member.

[0030] FIGS. 5A-5C are several side views which demonstrate the operation of the Foot Engagement Member 20. As seen, the Dual Lever Assembly 23 is basically comprised of two levers, each pivotally mounted at its proximate center to a Lever Support Member 24, and pivotally mounted at their opposite ends to the Foot Support Members 21. The Dual Lever Assembly provides a reciprocating upward and downward motion in the Foot Support Members 21, while also allowing the Foot Support Members to maintain a substantially horizontal position. Since the length of the Lever Support Member remain constant, the Foot Support Members will follow a curved upward and downward path of motion, which provides better exercise than steppers in which the foot support members follows a straight upward and downward path of motion.

[0031] FIGS. 6A-6C are several top views which demonstrate the operation of the Foot Engagement Member 20 in conjunction with the Guide Platform Member 14 of the Frame Structure Member 10. As seen, the Foot Support Members 21 have Platform Engaging Members 22 which extend outward and engage the Guide Platform Member 14 as the Foot Support Members 21 move in the upward and downward directions. The Guide Platform Member is mounted to the base frame member at a predetermined angle, with the bottom of the Guide Platform Member being closest to the Foot Engagement Member 20. As the user presses downward upon one of the Foot Support Members 21, the Platform Engaging Member 22 engages the Guide Platform Member 14, causing the Foot Support Member 21 to move in the direction away from the Guide Platform Member 14 as it moves downward. When the user pushes downward upon the opposite Foot Support Member 21, it will also engage the Guide Platform Member 14, causing it to move in the direction away from the Guide Platform Member 14 as it moves downward. This back and forth movement of the Foot Support Members 21 causes the Foot Engagement Member 20 to pivot in the side to side directions. Thus, as the Foot Support Members move in the opposite upward and downward directions, they also move on the opposite forward and backward directions. FIGS. 5A-5C show the Foot Support Members from the view of the Guide Platform Member, and the positions of the Foot Support Members in FIGS. 6A-6C correspond directly with those shown in FIGS. 5A-5C.

[0032] FIG. 7 is a demonstration of the engagement between the Platform Engaging Member 22 and the Guide Platform Member 14. It is preferable that each of the Platform Engaging Members 22 have a rigid Support Structure 22A which connects to and extends away from the respective Foot Support Member 22. At the ends of the each Support Structure 22A is a Wheel Component 22B, which rolls against the flat portion of Guide Platform Member 14. The outer surface of the Wheel Component 22B is preferably curved, so that it maintains better contact with the Guide Platform Member 14 as it moves in the backward forward, upward and downward motions along the platform surface. The path along which the Wheel Component 22B moves against the Guide Platform member 14 will be curved, and therefore the contact between the two will not be perpendicular to Support Structure 22 most of the time.

[0033] FIGS. 8A and 8B demonstrate adjustment features of the Platform Engaging Member 22 and the Guide Platform Member 14. By changing the angle at which the flat surface of the Guide Platform Member 14 is mounted, and by changing the distance between the Wheel Components 22B and the Foot Support Members 21, it is possible to change the amount of pivot in the Foot Engagement Member 20. Guide Platform Member 14 may have adjustable support members which allow its flat surface to be adjusted and secured at different angles. Also, the Support Structures 22A may be adjusted and secured along Foot Support Members 21 so that the distance between the Wheel Components 22B and Foot Support Members 21 may be altered in order to correctly operate with the new angle of the Guide Platform Member 14.

[0034] Many variations of the numerical display apparatus exist, along with the configurations described above. While it will be apparent that the preferred embodiment of the invention herein disclosed is well calculated to fulfill the objects above stated, it will be appreciated that the invention is susceptible to modification, variation, and change without departing from the proper scope or fair meaning of the subjoined claims.
