This application is a continuation-in-part of U.S. patent application Ser. No. 14/308,494, which was filed on Jun. 18, 2014 and entitled “Hand-Held Centripetal Exercise Device.” The complete disclosure of the above application is hereby incorporated by reference for all purposes.
BACKGROUNDThis invention relates in general to hand-held exercise devices and more specifically to such devices intended to be swung in a rotational manner. The process of swinging this device produces resistance in the form of kinetic reaction to inertia, gravity, and centripetal force. The invention acts as a hand-held exercise device employing centripetal resistance for use in conjunction with overall physical fitness, muscular strengthening and conditioning, joint flexibility, coordinated movement, and physical rehabilitation.
DESCRIPTION OF THE PRIOR ARTThe benefits of exercise are well known for an individual's health and well-being. While there are many opportunities to exercise there exists a need to exercise without cumbersome or complex equipment. Over the years many hand-held devices have been developed to aid in the quest to achieve strength, flexibility, and endurance. Most such devices are prohibitively complicated for widespread adoption as the listed patents below illustrate.
Shahinian U.S. Pat. No. 5,904,640 discloses an extended centripetal rotator exercise device with an elongated tubular member such that when the device is grasped at each end and moved toward and away the end members move circularly relative to the tube.
Dantolan U.S. Pat. No. 6,228,002 discloses a hollow metal tube with a hand grip on its upper end and a rotatable weight on its lower end. When holding the hand grip and moving the rotatable weight, one can exercise various portions of the body.
Petrosky U.S. Pat. No. 4,982,950 discloses a device providing two tubular structures and a solid cylindrical bar through a shorter tubular structure which is secured to a perpendicular longer tubular structure. The exerciser is manipulated through a repetitive hand, wrist or arm motion while holding the shorter tubular section.

Additionally, there are many hand-held devices intended for use while the body is in ambulatory. Here again, these devices are either overly complicated, and/or do little to enhance the basic exercise.
For example: Byrd U.S. Pat. No. 4,610,447 discloses an enlarged, hollow, spherically shaped body having diametrically opposed apertures which permit access to the interior of the body for the storage of items useful to the jogger.
Heck U.S. Pat. No. 5,407,401 entitled Hand-held Aid for Human Locomotion, wherein is described a lightweight, rigid, non-compressible device which is held in the hand and which aids in locomotion.
WO 1 992004954 A1 discloses an ambulatory exercise device which comprises a flexible elongated rod, selectively weighted, such that the rod is capable of sustaining controlled, rhythmical and periodic oscillation corresponding roughly to the natural movements of an exercisers arm.

BRIEF SUMMARY ObjectsThe object of this invention is to provide a safe, simple, and fun apparatus for upper body exercise. When swinging the device in a rotational arc, the resultant centripetal force is transmitted as physical resistance upon the users' neuromusculoskeletal system. This resistance produces a safe and effective low-impact form of exercise. Benefits of swinging the device include strengthening, toning, and increasing muscle and joint flexibility in the upper body. Benefits may be achieved while standing, walking, or jogging.
AdvantagesThe devices simplistic design and function lends itself to users seeking a new or renewed interest in exercise.
Its design allows for the manipulation of a natural phenomenon (centripetal force) to be utilized in a daily fitness regimen. Use of the device produces a physical engagement, variety, and enjoyment not found when performing the same motions without the device.
When the device is used while the body is in forward motion, there is an increase in coordination between the movements of the upper and lower body and a strengthening and toning of the user's core muscle groups.

In the example shown in
Typically, inner ball 2 is a singular and solid body having a mass to match the requirements of the user. For example, the mass of the inner ball may range from about 2 ounces (56 grams) to about 10 ounces (283 grams). The size of the inner ball may be about 40 to 80% smaller than the inner volume of the outer shell. Inner ball 2 may be made of suitable material(s), which may be the same or different from the material(s) of outer shell 1. For example, inner ball 2 may be made of one or more metals, such as lead.
Hemispheres 3 and 4, when used, may be permanently or fixedly attached, such as via welding and/or adhesives (e.g., welding glue). Alternatively, hemispheres 3 and 4 may be removably attached or removably connected such that separating the hemispheres allows for inner ball 2 to be exchanged (e.g., via hinges, handles, etc.). For example, one or more both hemispheres may include a twist lock (not shown), hinges, pivots, latches, and/or other mechanism(s). When the hemispheres are removably attached, inner ball 2 may be removed and replaced with another inner ball 2 of different mass and/or other characteristics. Changing the inner ball allows the user to change weight therefore varying the consequent effects.

In any of the above embodiments of the hand-held centripetal device of the present disclosure, those devices may additionally include an outer layer 20, as shown in dashed lines in
When swung in a rotational motion a centripetal force is created producing a low-impact resistance exercise. The user can vary the size and direction of the rotations to target desired muscle groups. Exchanging the inner ball allows the user to vary the weight and therefore the level of resistance.
When used while the body is ambulatory. The device acts to engage the shoulders, torso, and hips, enhancing the effects of the body's drive through space. Being simple in materials and construction, the device has a utility that is unique and not found in any other hand-held exercise devices. That it is used in a rotational motion produces a safe, effective and low-impact form of exercise. That it promotes a coordination of movement between body parts enhances the users' engagement and level of enjoyment.
It will be appreciated that the invention is not restricted to the particular embodiment that has been described, and that variations may be made therein without departing from the scope of the invention as defined in the appending claims, as interpreted in accordance with principles of prevailing law, including the doctrine of equivalents or any other principle that enlarges the enforceable scope of a claim beyond its literal scope. Unless the context indicates otherwise, a reference in a claim to the number of instances of an element, be it a reference to one instance or more than one instance, requires at least the stated number of instances of the element but is not intended to exclude from the scope of the claim a structure or method having more instances of that element than stated. The word “comprise” or a derivative thereof, when used in a claim, is used in a nonexclusive sense that is not intended to exclude the presence of other elements or steps in a claimed structure or method.
