Description

BACKGROUND OF THE INVENTION

1. Field of the Invention (Technical Field)
The present invention relates generally to exercise devices, and more particularly to body exercise equipment that utilizes a resistance force to provide the user with rotational, as well as linear force to exercise.
2. Description of Related Art
Athletes, as well as physical therapists, have understood the need to strengthen, increase range of motion, and improve proprioception of the various parts of the body. Most commonly, fitness devices provide the user with an opportunity to extend and/or retract their limbs and/or torso, while acting against some kind of resistance force provided by the apparatus. This is referred to flexion and extension of the muscles. Rotational strengthening of various parts of the body provides a unique method of strengthening the body, as opposed to flexion and extension. Rotational strengthening involves supination, and pronation of the limbs, in whole or in part, as well as left and right rotation of the neck, spine, or both. It is currently difficult to exercise the body in a rotational fashion because current inventions provide the user with an opposing linear force, rather than an opposing rotational force to interact their muscles against. There are several muscles, and groups of muscles which benefit directly from rotational strengthening. While some currently available devices utilize rotational force for exercising, these systems lack in the ability to select the range of motion, as well as allow the user to attach several different unique attachments. There is a current need for a device which allows the user to gain strength by working against a restrictive force, in a rotational fashion, with multiple parts of their body. Furthermore, exercise equipment users are often limited in area to accommodate exercise equipment, therefore exercise apparatuses should ideally take up a small amount of space while providing many functions.
Embodiments of the present invention preferably allow the user to adjust the range of rotation that an exercise apparatus will encompass relative to the user. This allows users to strengthen their muscles more completely, and increase range of motion. Embodiments of the present invention preferably allow users to adjust the height of an attachment point for various attachments. This allows people of differing heights to utilize the same machine after adjusting it to their height. Embodiments of the present invention allow the user to rotate the attachment point in a plane that is perpendicular to the plane of the force rotation of the attachment point, resulting in a downward, sideward, and upward plane for connecting the various attachments. Embodiments of the present invention allow the users to supinate, pronate, rotate, and/or twist the hand, wrist, forearm, elbow, upper arm, shoulder, neck, spine, lumbar, hip, upper leg, knee, lower leg, ankle, and/or foot, utilizing attachments, or no attachments while working that same motion against resistance force as low as zero pounds of force, in a bidirectional fashion. In addition, embodiments of the present invention provide versatile equipment that uses little space.

BRIEF SUMMARY OF THE INVENTION

Embodiments of the present invention comprise an exercise apparatus comprising an adjustable rotating element around which a force transferring material wraps either clockwise or counterclockwise to provide bidirectional rotational resistance for exercising, and the force transferring material guided to remain in close proximity to the rotating element while wrapping around said rotating element. In one embodiment, the rotating element is a circular wheel. In one embodiment, the circular wheel is capable of accommodating the force transferring material on its periphery, for example in a groove. In one embodiment, the force transferring material is selected from the group consisting of a cable, a belt, a chain, a rope, and a rubber band, preferably guided with pulleys disposed in proximity to the rotating element. In one embodiment, the rotating element adjusts horizontally between 1 and 360 degrees vertically and between approximately 1 foot and approximately 10 feet high. In one embodiment the apparatus comprises interchangeable attachments disposable on the rotating element, such as a head accommodating attachment, a long shoulder handle attachment, a twin free spin plate, etc. In a different embodiment, an attachment for a particular exercise is permanently affixed to the adjustable rotating element.
One embodiment comprises a connectable attachment for a bidirectional rotating resistance exercise apparatus comprising a surface on which a user places the user's hand to strengthen the user's shoulder joint and elbow joint and wrist joint and related muscles in supination, pronation and rotation motions.
One embodiment comprises a connectable attachment for a bidirectional rotating resistance exercise apparatus comprising a surface on which a user places at least one foot of the user to strengthen the user's hip joint, knee joint, ankle joint and spine and related muscles in supination, and pronation, and rotation motions.
One embodiment comprises a connectable attachment for a bidirectional rotating resistance exercise apparatus comprising a knee cradle on which users place one knee to strengthen the user's hip joint and related muscles in supination, pronation, and rotation motions.

DETAILED DESCRIPTION OF THE INVENTION

In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the invention. However, upon studying this application, it will be understood by one of ordinary skill in the art that the embodiments may be practiced without these specific details. For instance, well known operation or techniques may not be shown in detail. Technical and scientific terms used in this description have the same meaning as commonly understood to one or ordinary skill in the art to which this subject matter belongs.
As used throughout this specification and claims the term “rotate” means to turn around a center of rotation in a clockwise, or counterclockwise motion. As used throughout this specification and claims the term “rotating element” means a component to which a force transmitting material is connected to, for example, be wrapped around to provide rotational resistance, and comprises, for example, a circular, elliptical, rectangular, triangular, or the like, shape. As used throughout this specification and claims, the term “force transmitting material” means a component by which force is exerted to provide resistance, including, but not limited to, a cable, rope, chain, belt, rubber band, and the like. Similarly, as used throughout this specification and claims the term “rotational” means to rotate as in, for example, moving in a circular manner, etc. As used throughout this specification and claims, the term “Pronation” means to rotate towards the center of the front of the body, while the term “Supination” means to rotate away from the center of the front of the body.
Working muscles against resistance in a rotational motion improves the stability of the body part being exercised. The improvements in strength are accompanied by a better understanding of the body, and its range of motion. This new understanding of the body, allows the user of embodiments of the present invention to become more stable, and stronger overall. Rehabilitation, injury prevention, and overall strength of certain body parts can be accomplished very quickly when rotational resistance such as the one provided by embodiments of the present invention is utilized as part of an exercise routine.
Generally, rotational motions of the body occur when naturally moving the body while, e.g., walking, running, biking, swimming, throwing, jumping, using tools, and many other motions routinely performed by the body. Strengthening the rotational aspects of the body makes a person's body more strong overall and helps to heal or prevent injuries.
Furthermore, most users of exercise equipment have a limit in the amount of space they can allot to be used by one piece of equipment. A piece of exercise equipment that has multiple functions built into one unit saves real estate space to be used for another purpose.
In one embodiment, a bidirectional force is created by changing the direction of an initially linear force. This is accomplished by changing the linear direction of the original force, for example, a force transferred by a cable, into a force acting upon the tangent of a circumference. When the force acts upon the tangent of the circumference, it gives the user a force to counteract in a rotational fashion. There is no need, in the embodiments of the present invention, for the user to support the perpendicular forces of the exercise motion; the user needs only to rotate around the centerline to counteract the bidirectional opposing force.
In a different embodiment, bidirectional rotational resistances is accomplished through, for example, braking systems, friction, magnetic devices, electric devices, springs, stretching a flexible material, hydraulic devices, pneumatic devices, and the like.
The bidirectional opposing force offered by the various embodiments of the present invention allows the user to exercise clockwise, and counterclockwise movements as needed for the various attachments. The bidirectional feature of the present invention is beneficial to the user due to the fact that the body parts rotate in both directions, and those rotations are made possible through muscles which will benefit from resistance exercise.
Referring to FIGS. 1-3, in one embodiment, exercise apparatus 10 comprises original linear force X preferably with a linear direction and preferably being transferred by a force transferring material, such as cable 12. Cable 12 is preferably connected to weights 14 at one end and to wheel 16 at its opposite end. In one embodiment, wheel 16 has a circular shape and comprises groove 18 on its periphery to accommodate cable 12 when turned in either a clockwise or a counterclockwise direction. Optionally, wheel 16 comprises a shape other than circular, for example, elliptical. In one embodiment, a mechanism is provided to guide cable 12 as it wraps around wheel 16, for example, pulleys 17 are preferably disposed on either side of cable 12 relatively near wheel 16 (e.g., most preferably between approximately 0.25 inches and approximately 6 inches), to guide cable 12 into groove 18, thus maximizing transition of force from cable 12 to wheel 16. Preferably, wheel 16 is mounted onto moving axle 20 preferably comprising, for example, bearings 22 (not shown). Preferably wheel 16, is connected to axle 20, e.g., welded, bolted, etc. In one embodiment, Axle 20 inserts into hub 25, and nut 27 (not shown) is then placed on an end opposite to the end where wheel 16 is disposed. Preferably cable 12, is attached to wheel 16 by placing cable ball 21, into cable receiver 19. Bi-directional motions which act upon cable 12 in a motion, which lifts weights 14, are commenced by the user spinning wheel 16, alone, or optionally with an attachment.
In one embodiment, attachments for various exercises are preferably secured onto wheel 16 through, for example, one or more easy insertion/release pins, which optionally pass through center perforation 28, on wheel 16, and/or optionally pass through off center perforations 26. Wheel face 30 preferably is a substantially flat plane surface of wheel 16, through which easy insertion/release pins pass in a perpendicular plane of motion. Quick release of the attachments allows the user to quickly change the optional attachments if so desired, thus saving time.
In one embodiment, a free end of the force transferring material is made available to the user, with for example, cable attachment 31, in order to provide an attachment point for several different pre-existing attachments. This provides an optional value added feature. This attachment point offers the user linear force resistance with which to use to strengthen the body in a linear fashion.
Embodiments for attachments for wheel 16, for instance, a grip handle, are unique from existing similar inventions in the way that they align the center of rotation of, for example, the user's wrist with the center of rotation of the opposing force. Competing devices force the user to move the centerline of their wrist rotation off of the center line of rotation of the opposing force, thus forcing the user to experience a movement which is not naturally aligning with their body.
In a preferred embodiment, exercise apparatus 10 preferably comprises adjustable wheel platform arm 32. Preferably the position of wheel platform arm 32 can be adjusted vertically to various heights to accommodate different users. For example, a user can release lock 34, which preferably holds wheel platform arm 32 in place on center post 36, and raise or lower wheel platform arm 32 to a desired height position. Optionally, counterweight 38 will assist the user in lifting or lowering wheel platform arm 32 which is preferably connected to counterweight cable 40. Preferably counterweight cable 40 is guided through pulleys 42 in order to change the downward force of the gravitational force acting upon counterweight 38, into an upward force acting upon wheel platform arm 32. Preferably friction reduction materials 43 (not shown), such as rollers, brushing, bearings, and the like, are placed between wheel platform arm 32, and center post 36 in housing 51.
Preferably, a user can adjust wheel platform arm 32 to multiple horizontal positions which allow use of various attachments for different exercise routines. For example, the user can insert easy insertion/release pin 46 through wheel platform arm pin hole 48, and through a degree selection hole 50. Preferably friction reduction materials 44 (not shown), such as bearings, rollers, and the like, are placed between wheel platform arm 32, and center post 36. Easy rotation of wheel platform arm 32 is made possible with friction reduction material 44 placed between wheel platform arm 32 and friction material housing 52. Preferably cable 12 follows the center of rotation of wheel platform arm 32, as wheel platform arm 32 is rotated to user's selection of degree selection holes 50. Preferably the first pulley 54 guides cable 12 in a direct path to cable receiver 19, optionally said path is also the center of rotation of wheel platform arm 32. Preferably support handle 60 is disposed on or hear center post 36 or other post of the apparatus, and is adjustable to move in/out and up/down, or be folded out of the way while remaining attached to the apparatus. Alternatively, support handle 60 is detachable.

Preferably the user will change position of elbow cradle handle 102 by, for example, unscrewing it from threaded handle mount selection hole 104 and, for example, screwing it into the desired threaded handle mount selection hole 104. Preferably elbow positioning bumpers 106 keep the user's elbow in the position of directly over the center of rotation of wheel 16. Preferably the user can utilize elbow cradle attachment 100 with wheel 16 oriented in a vertical or horizontal plane relative to the wheel face 30.
