2. Information Disclosure Statement
The following patents represent various types of devices with handles and flexible connections:
U.S. Pat. No. 3,323,796 describes a jousting apparatus comprising two sticks joined together with an universally flexible rope-like connecting member well anchored within the respective stick ends and having the portion intermediate its anchored ends which is long enough to allow multiple angular, lineal and rotative relative motions of the respective anchoring stick ends, wherein said flexible rope-like connecting member portion is about five stick diameters in length and the overall stick length is about thirty-eight stick diameters in length, said stick length approaching a jousting participant's waist height.
U.S. Pat. No. 3,454,274 describes an apparatus for teaching a youngster the art of self-defense. The device comprises two elongated handle members secured together at one end by an elastic cord. The handle members have noise making devices at their free ends.
U.S. Pat. No. 3,608,899 describes a hand weapon, generally similar in usage to a nightstick or baton, comprising two rigid elongated members, each connected to one end to the other by a nonrigid element such as a length of chain, whereby each member may swing relatively independent of the other, within the limitation imposed by the chain with respect to separation of the connected ends of said members, each member being provided with a hand-gripping portion adjacent the free end thereof whereby one member may be grasped in each hand and utilized in cooperation with each other, or either member may be grasped and the other member permitted to swing loosely.
U.S. Pat. No. 3,934,877 describes an invention that related to a police weapon comprised of two rigid elongated sticks joined at one end by a flexible thong to enable disposing them side by side when the weapon is not being used but to permit whirling one about the other is use and especially to making the sticks if rigid and relatively flexible portions to make the weapon less lethal in use.
U.S. Pat. No. 4,018,441 describes a training exercise device combining a jump-rope with a pair of hand covering elements, such as boxing training gloves, mittens or the like, provided with means for releasably connecting one end of the jump-rope to each of the hand covering elements.
U.S. Pat. No. 4,593,899 describes a jumping rope for exercising including resiliently flexible handles for adjustably altering the moment of force imposed upon the user by the swinging rope. The jump rope construction includes evenly extended handles at each thereof. The interval between the extended handles and a ball bearing assembly within which the rope is secured comprises a resilient member which will vary the torsional force along its longitudinal axis. The rope is joined to the handle section by a ball bearing assembly which is recessed from the handle shoulder. The handle section adjacent the rope is a terminal coupling and has a tapered cross-section at the shoulder thereof to reduce the friction between the rope and the shoulder of the handle section. The opposite end of the receiving handle section is joined to a mating extension which resiliently bends along its longitudinal axis and can be easily gripped by the user. The flexibility of the resilient member is in response to the rate of rotation of the rope and thereby changing the effective distance between the user's hand and the point at which the force of the swinging rope will be applied to the handle.
U.S. Pat. No. 4,934,691 describes a length of rope of the type utilized in a present jump rope, with an extended handle portion at each end of the length of rope. Each of the handle members would comprise a main cylinder having bore throughout its length, with the length of the rope threaded through the bore. Intermediate the rope body and the wall and the handle, there would be provided a resilient spring member extending substantially the length of the handle, and, with the end of the rope extending out of and secured to the distal end of the spring, with the proximal end of the spring secured within the handle, so that pulling the handles away from one another compresses the coil springs and establishes an exercise force of the user.
Notwithstanding the prior art, the present invention is neither taught nor rendered obvious thereby.
SUMMARY OF THE INVENTION
The present invention is a virtual jump rope device that includes a pair of virtual jump rope units. Each of the units is elongated and has a first end and a second end. Each of the units has a handle portion at its first end, a middle portion and a weight portion at its second end. The handle portion has a predetermined length, and is adapted for manual griping. The middle portion is connected to an end of the handle portion and extends therefrom. The middle portion has a length greater than the predetermined length of the handle portion.
The weight portion is connected to the middle portion remotely from the handle portion. The weight portion has a weight greater than at least 1 ounce, and it may be permanently attached to the middle portion or removably attached thereto. The weight portion preferably has a weight greater than 3 ounces and may be heavier than 5 pounds. Most users would be very uncomfortable with weights greater than 6 pounds, and the weight choice could be made by the user. Thus, different weight sizes and middle portion lengths may be offered to permit users to try out different sizes and to increase sizes and/or weights with experience.
The handle may be made of wood, plastic, metal or other strong material, or combinations thereof. The middle portion may be selected from the group consisting of rope, cord, strip, chain and braid. In some preferred embodiments, the middle portion is made of material selected from the group consisting of natural material, synthetic material, and combinations thereof. In some preferred embodiments, the middle portion is made of rope, may be natural rope, synthetic rope, or combinations thereof. It could be flat strip material, cordage, circular, hexagonal, or other formed cross-sectional elongation. It preferably may be an extruded synthetic material.
The present invention virtual jump rope middle portion has a predetermined length of about 8 inches to about 36 inches. The virtual jump rope middle portion has a preferred predetermined length of about 16 inches to about 26 inches. The virtual jump rope weight portion may be metal or other dense material, and, although not required, for safety reasons it may include a dense inner member and an impact cushioning outer member. This impact cushioning outer member may be a plastic coat, a leather cover, a foam layer, a rubber layer or other similar material, but compressible foam layer is preferred.
In some preferred embodiments, the present invention virtual jump rope further includes a rotatable interconnector located between the handle portion and the middle portion, said interconnector permitting 360° rotation about an axis of that middle section relative to the handle section. The interconnector could be a universal joint, a simple single axis free connection, e.g. a rope and a washer, or other device that would permit rotation. On some preferred embodiments, the rotatable interconnector includes ball bearings, e.g. encased in an annular arrangement, for extremely smooth, fast rotation of an axle to which the middle portion may be attached.
In some embodiments, the present invention virtual jump rope weight portion is removably attached to the middle portion, e.g., by hook, clip, screw, or other fastener. Preferably, there are a plurality of middle portion weights and are interchangeable with one another. Thus, a user may start out with lighter weights and increase the weight over time, or may try out different weights to select the one most comfortable.
In other embodiments, the present invention virtual jump rope handle portion is hollow and the middle portion is partially slidably mounted therein so as to be adjustable as to the length of middle portion external from the handle. The handle portion preferably includes a clutch for engagement to prevent movement, and disengagement to allow movement, of the middle portion. This allows the device to be used with the middle portion fully extended in one direction for jumping exercises, or evenly extended from both ends of the handle for wrist and arm exercises.
