## Title
Abdominator: abdomen and obliques exercise machine

## Abstract

The present invention describes a specialized exercise apparatus and method for use that targets the muscles in and around the abdominal, oblique muscles and mid section of the body. The machine is comprised of a flat platform upon which an individual stands while grasping a pair of handlebars that are positioned at waist height. The handle bars are attached to the top of a vertical riser that extends downwardly and is attached to a pair of horizontal rotating pivot arms. The pivot arms are attached to the center of a rotating power pulley horizontally suspended by bearings below the forward area of said platform. The power pulley is connected by a belt to a resistance mechanism, such as a flywheel or turbine fan, again suspended by bearings, below the rear portion of said platform. In the flywheel adaptation of this invention, additional resistance is provided by an adjustable magnet that is controlled by a lever mounted to the side of the vertical riser. An individual stands upon the apparatus, and while keeping the lower body relatively stationary, rotates the handle bars, and thus the pivot arms, from side to side up to 220 degrees of rotation and provides an adjustable measure of resistance which produces an increased use of the muscles in and around an individual's torso and midsection area.

## Background
BACKGROUND OF THE INVENTION
1. Field of Invention
This invention relates generally to an exercise machine and method of use that primarily targets the abdominal and mid-torso muscles of an individual, but also serves to strengthen the entire body as well as provide a cardiovascular/aerobic workout.
2. Background
The inventor, a licensed Chiropractor in the state of California for the past 21 years, has been looking for tools that would allow him to better serve his patients. One of the problems the inventor often encountered were patients that needed to tone and strengthen their torso area so as to alleviate back strain by tightening and strengthening the abdomen, the oblique abdominis muscles, and the erector spinae muscles. However, many of these patients were unable to lie supine on the ground, kneel on the ground, or even sit for very long to perform more traditional torso strengthening exercises using traditional exercise equipment without feeling large amounts of discomfort.
While in the grocery store one day, with a fully laden cart, the inventor swung the cart in an arc while he pivoted at the waist. He immediately noticed how that movement, coupled with resistance, targeted the torso area. He also noticed that although it significantly targeted the torso area, it was a relatively easy movement to make and that by simply standing and rotating one's body with resistance one could effectively work on the muscles in the torso area.
Thus, this invention was originally designed to rid the body of “lovehandles”, or oblique muscles and to strengthen the back muscles at the same time. In addition, the machine works the entire body both, strengthening the majority of the muscles and aerobically working the heart muscle.
The primary muscle groups that this invention isotonically targets on the anterior portion of a human body are the a) oblique abdominis muscles (“lovehandles”); b) rectus abdominis Muscles; c) biceps brachii muscles; and the d) pectoralis muscles. The primary muscle groups that this invention isotonically targets on the posterior portion of a human body are the a) erector spinae muscles; b) latissimus dorsi muscles and c) triceps brachii Muscles.
The primary muscle groups that this invention isometrically targets on the anterior portion of the human body are the quadriceps femoris muscles. The primary muscle groups that the invention isometrically targets on the posterior portion of the human body are the a) gluteal muscles (muscles that comprise the buttocks and allow a person to remain in an erect posture); and b) biceps femoris muscles (muscles on the back of the upper leg that enable a leg to bend).
One of most positive aspects of this invention is the possible life extension it may bring by using the machine on a regular basis, especially today with the ballooning of bellies, and the early death from Diabetes and Heart Disease. Recent studies show that there is a direct correlation between a person's waist size and both Heart Disease and Diabetes. This invention not only strengthens all the core muscles needed for good posture and good health, but it aerobically burns calories at a high rate of speed, slimming down your waist size. Only a short period of time on this invention and an individual will feel as if they have had a complete aerobic workout.
The machine can be used by anyone, young or old, in shape or not, male or female. The resistance is only as difficult or easy as an individual desires, and thus it is safe for everyone. An individual does not have to lie supine or kneel. For some people it is very difficult for them to kneel or lie supine due to arthritis, knee injury, obesity, etc. With this invention an individual only has to be able to stand and grasp a handle and rotate clockwise and counterclockwise by keeping the lower body stationary and by rotating the upper body from the pelvic area. In addition, this invention is a tremendous strengthening and stretching device for all athletes, especially golfers, baseball players, tennis players, etc, as this invention strengthens the core muscles in the midsection which are needed for all sports.
3. Description of Related Art
There is a plethora of exercise apparatus and methods of exercising that already exist. The core area of the human body (as defined by the oblique abdominis muscles, the rectus abdominis muscles and the erector spinae muscles) is, however, one area which is difficult for many individuals to exercise to tone muscles and reduce fat.
Many of the exercise apparatuses that exist focus on the strengthening or toning aspects of the core region. The ongoing problem with the existing exercise apparatuses that focus on the core body is twofold. First, as is well known in the health field, the physical fitness field and in the nutrition field an individual cannot “spot reduce” fat from any part of the body and that well know fact is especially true of the core area, or lovehandle area. The only way to reduce fat is to either reduce calorie intake and/or to promote aerobic activity. Most of the extant exercise apparatuses focus solely on strengthening the core muscles and thus do not address the need to reduce fat through aerobic exercise.
For example, U.S. Pat. No. 6,669,610 claims a method and apparatus for exercising internal and external oblique muscles by utilizing lateral forces generated by the feet while maintaining the upper body in a fixed position to facilitate exercise of the oblique muscles. The U.S. Pat. No. 6,669,610 patent targets the oblique muscles but neglects to take an aerobic workout into consideration. The present invention is patently distinct in a number of ways. First, in order to provide an aerobic workout and to further increase the strengthening benefit the present invention has an active resistance mechanism rather than using the passive weight of an individual's own body. Second, the present invention provides varying levels of resistance based on the active resistance mechanism used, and through the use of a variable resistance magnet. Third, in the present invention an individual's lower limbs are optionally stabilized while the upper body does the work—which is very different from other prior art. This means that not only are the abdomen and oblique muscles exercised, but the entire upper body muscles are also exercised as well (such as the biceps, triceps, latissimus dorsi, and pectoralis muscles). Fourth, because the lower limbs are held in a stable position while rotating the upper body the lower limbs and muscles are working and thus a complete aerobic workout is had. Beyond these distinctions there are many other differences that one skilled in the art can easily see by reading the specification below.
Thus, what is desired is a safe, yet effective, aerobic and muscle strengthening apparatus and method of use so that an individual can achieve both an aerobic workout while toning the core muscles of the body.
4. Objects of the Present Invention
Based on the background, long felt need and lack of an apparatus in the related art to address that long felt need, the following objects of the present invention are discussed.
It is an object of the present invention to provide an apparatus that an individual may employ while in an upright standing position to exercise the “core” muscles, as well as providing an aerobic workout, by using a low impact resistance based method.
It is a further object of the present invention to allow an individual to perform exercises used to primarily isolate the oblique abdominis muscles (“lovehandles”), the rectus abdominis muscles, and the erector spinae muscles
It is an additional object of the present invention to provide an apparatus that an individual may employ to release vertebral fixations and loosen tight back muscles in a chiropractic fashion by rotating the upper body from the pelvic area while keeping the lower body stationary.
It is another object of the present invention to provide an adjustable height for the handlebars to accommodate different heights of individuals and to allow an individual to achieve a comfortable grasp of the handlebars while exercising.
It is a further object of the present invention to provide an apparatus and method of use that is safe for most every individual, despite most any physical limitation said individual may have, or regardless of the fitness level of any one particular individual.
It is a further object of the present invention to provide a method for adjusting the amount of resistance experienced by an individual while exercising without forcing an individual to stop or change position.
It is an additional object of the present invention to have as few moving parts and minimal wear as possible.
It is a further object of the present invention to provide a means to move the machine with minimal effort and to allow a method of storing the machine while not in use.
These and other objects and advantages of the present invention will be apparent from the following specification and accompanying drawings.
SUMMARY OF THE INVENTION
With the foregoing background in mind, it is the objective of the present invention to create an exercise apparatus and method for use. This exercise apparatus or exercise machine lies horizontally along the floor and is for use in a standing position. An individual, while grasping a pair of handle bars, rotates his or her body from the pelvic area upwards while maintaining a forward stable stance from the pelvic area downwards. This movement, in turn, moves the handlebars from side to side which moves a vertical riser, which moves the pivot arms, with said pivot arms being attached to the resistance mechanism. This action provides significant use of mid and torso muscle groups and helps to exercise the waist, hips, and stomach areas of the body as well as many other major muscles, including the heart.
The present invention provides a machine that an individual stands upon while grasping a pair of handlebars distally mounted to a rigid vertical riser, which pivots from side to side of the machine up to 220 degrees of arc. The present invention further comprises of an attached pulley and flywheel that is rotated in either direction by the attached vertical riser and handlebars and provides dynamic resistances in each direction as an individual moves the handlebars. This resistance increases at the beginning and end of each motion thus creating a bi-directional use of various muscle groups. In addition, the present invention also describes a magnetic brake, which may be adjusted to vary the constant amount of resistance experienced by an individual. The variable resistance can be adjusted from a lever mounted just below the handlebars while exercising to increase or decrease the level of effort needed to suit an individual's preferences.
In an alternate embodiment the resistance mechanism is a turbine fan. As an individual speeds up his or her rotational motion, the turbine fan turns faster thus generating more air resistance. It is anticipated that the turbine fan resistance mechanism will be lighter in weight than the flywheel resistance mechanism, and thus more suitable for home use.

b. Power-Pulley and Horizontal Pivot Arms
With reference to FIG. 4 and additional reference to FIGS. 1, 2 and 3 the present invention is further shown to be comprised of pivot arms 13 attached at the ends of the vertical axles of a power pulley 14. The horizontal upper and lower members of the pivot arms 13 are keyed and mated to the ends of the power pulley 14 axle and are held in place by bolts threaded into the center of the power pulley 14 axle.
It is further shown that the power pulley 14 is itself held in place by its lower axle, which is pressed into a power pulley bearing 15. The power pulley bearing 15 is further held in the forward facing support structure of the main chassis 3 by a forward bearing housing 16. The power pulley 14 is free to rotate on its lower axle via the power pulley bearing 15 in either direction driven by the attached horizontal upper and lower members of the pivot arms 13.
With the attached handlebars 6 and vertical riser 7 connected to the forward vertical member of the pivot arms 13 attached to the power pulley 14, the power pulley 14 is driven in either direction of travel from a first forward center position to either side with up to approximately 220 degree of total horizontal arc travel. As an individual moves the handlebars 6 from side to side the power pulley 14 is rotated in the like directions by the attached pivot arms 13.
c. Flywheel and Power Pulley
With continued reference to FIG. 2 and FIG. 4 the preferred embodiment of the present invention further shows a flywheel 19 comprised of a heavy solid circular disc with a center axle and flywheel pulley 21 located on the top side of the flywheel 19. The flywheel 19 is driven by a drive belt 18 attached between the flywheel pulley 21 and the power pulley 14. The flywheel 19 is held in place by its upper and lower axles which are further held by flywheel bearings 20. The flywheel bearings 20 are further held by the rear members of the main chassis 3 rear bearing housings 17. The flywheel 19 is free to rotate about its upper and lower axles within the flywheel bearings 20.
With continued reference to FIG. 4 the preferred embodiment of the present invention further shows that the flywheel 19 is driven by the power pulley 14 by an attached drive belt 18. The drive belt 18 is fitted to the power pulley 14 and flywheel pulley 21 and drives the flywheel 19 in the same direction as the power pulley 14 when rotated by the attached upper and lower horizontal pivot arms 13.
In the preferred embodiment, the power pulley 14 is connected to the flywheel 19 with an eight to one induction ratio to create a degree of dynamic starting and ending rotational resistances. The flywheel 19 provides a measured amount of inertia induced resistance created each time the direction of the power pulley 14 is reversed given an individual more effort the further they move the handlebars 6 and vertical riser 7 from side to side.
d. Alternate Embodiment Using a Turbine Fan and Power-Pulley
With reference to FIG. 6 an alternate embodiment of the present invention is shown to use a turbine fan 26, as an alternative to a flywheel 19 as shown in FIG. 4. In this alternate embodiment the turbine fan 26 is comprised of a light weight circular disc with fan blades 27 radiating from the center axle and turbine fan pulley 28 located on the top side of the wheel. The turbine fan 26 is driven by a rubber drive belt 18 attached between the turbine fan pulley 28 and the power pulley 14. The turbine fan 26 is held in place by its upper and lower axles which are pressed into bearings 20 as shown in FIG. 2. The bearings 20 are further held by the rear members of the main chassis 3 rear bearing housings 17. The turbine fan 26 is free to rotate about its upper and lower axles within the bearings 20.
In this alternate embodiment the drive belt 18 is fitted to the power pulley 14 and turbine fan pulley 28 and drives the turbine fan 26 in the same direction as the power pulley 14 when rotated by the attached upper and lower horizontal pivot arms 13. In addition, in this incarnation of the present invention the power pulley 14 is connected to the turbine fan 26 with eight to one induction ratio pulleys to create a degree of dynamic rotational resistances. The turbine fan 26 provides an increased amount of induced resistance the faster an individual moves the handlebars 6 from side to side due to the air resistance generated by the increase in speed of the turbine fan. This creates a reactive induced resistance at the beginning and end of each repetition.
e. Adjustable Resistance Magnet
With reference to FIG. 1 and additional reference to FIG. 4 the preferred embodiment of the present invention is further identified with reference to a device comprising of an adjustable resistance mechanism. The adjustable resistance mechanism is comprised of a resistance lever 11, resistance control cable 12 and a resistance magnet 22. The present invention further shows that the resistance lever 11 is located and mounted to the side of the vertical riser 7 and is connected to the resistance magnet 22 by a control cable 12. When the resistance lever 11 is moved up and down on the side of the handlebar adjustment tube 32, the control cable 12 moves the resistance magnetic 22 from a first closer to a second further distance from the top surface of the flywheel 19.
With continued reference to FIG. 2 and FIG. 4 in the present invention, the resistance magnet 22 position is adjusted remotely by the control cable 12 connected to the resistance lever 11 and provides an adjustable amount of continuous resistance to the flywheel 19. This allows an individual to adjust the amount of magnetically induced resistance and thus increase or decrease the amount of effort needed to move the handlebars 6 and vertical riser 7 from side to side. The adjustable resistance allows an individual to increase and decrease the amount of overall constant resistance experienced while exercising.
The foregoing description details certain preferred embodiments of the present invention and describes the best mode contemplated. It will be appreciated, however, that no matter how detailed the foregoing description appears, the invention can be practiced in many ways without departing from the spirit of the invention. Therefore, the description contained in this specification is to be considered exemplary, rather than limiting, and the true scope of the invention is only limited by the following claims and any equivalents thereof.
