## Background
RELATED APPLICATIONS
This application claims priority from U.S. Provisional Patent Application Ser. No. 60/706,187 which was filed on Aug. 8, 2005.


TECHNICAL FIELD
The present invention relates to a weighted skipping exercise device, more specifically in combination a leg ring attached by a elongated cord to a cone shaped element containing adjustable weights.
BACKGROUND OF THE INVENTION
Skipping toys using a leg ring and object attached by an elongated cord have been known for many years for use primarily as amusement toys. In operation, the leg ring is placed around a user's leg and by continuous movement of said leg the attached object and elongated cord revolve in a circular path requiring the user to skip or jump over the elongated cord with the opposite leg to maintain continuous revolutions.
The prior art discloses variations of the revolving object to increase the amusement of these toys. One example is disclosed in U.S. Pat. No. 5,603,651 (Shure et al.) in which a bubble producing mechanism is enclosed in the revolving object. Another example is disclosed in U.S. Pat. No. 6,113,452 (McGowan et al.) in which the revolving object contains a marker for marking the surface as the object travels.
Another example is disclosed in U.S. Pat. No. 6,695,671 B2 (Kessler) which the revolving object is a wheel containing small lamps and a generator which light upon rotation.
The present invention has for its primary objective to provide a cardiovascular aerobic device utilizing an improved leg ring, an elongated cord and a cone element adapted for quick and easy adjustment of weights contained therein. Additional uses include leg shaping and conditioning, sports training and stress reduction.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a novel, interesting cardiovascular aerobic device that utilizes a leg ring, elongated cord and cone element that is safe to the user and provides different levels of cardiovascular conditioning and leg strengthening by adjusting the weight of the cone element.
A further object of the invention is to provide utility in sports training, aerobic exercise, stress reduction and amusement to the operator.
A further object of the invention is to utilize different weights inserted in the cone element for increased or decreased force on the leg attached to the leg ring.
A further object of the invention is the method for quick and easy adjustment of the weight contained within the cone element.
A further object of the invention is to utilize a friction device flange bushing in attaching the elongated cord to the cone element to prevent wearing of the cone and cord with rotation of the cone element.
A further object of the invention is to attach the elongated cord around the leg ring within a channel in the outer circumference of the leg ring providing increased strength of the elongated cord preventing breakage of the elongated cord with the use of the weighted cone element.
In accord with the invention, the weighted skipping exercise device is comprised of a leg ring, in the preferred embodiment constructed of plastic extrusion or other suitable materials, with a channel around the outer circumference to accommodate an elongated cord made of vinyl or rubber coated steel cable in the preferred embodiment, or other suitable materials. The leg ring opens to allow room for fitting over a user's shoe. The leg ring has a snap clip permanently attached to one end which connects to the second end when positioned around the user's shoe forming a continuous leg ring.
The elongated cord situated within the outer leg ring channel contains a oval stop sleeve, which completes the cord loop around the leg ring.
The oval stop sleeve is positioned on the elongated cord to provide a cord loop sufficient in circumference to allow the leg ring to be opened for placement over the user's shoe or for removal.
The elongated cord, at the end opposite the cord loop, is attached to a cone element by a cylindrical stop sleeve and flange bushing that allows the cone element to spin unrestricted without wear to the cone element or elongated cord.
The cone element, preferably made of ABS plastic or other suitable materials, consists of a top cone attached to the elongated cord, and a base cup threaded together by a friction ring.
The base cup consists of an interior cavity for retaining adjustable weights.
In operation, the elongated cord and cone element horizontally rotate from a circular motion of the user's leg with the leg ring attached, and the user's non-ringed leg is raised over the cone element to allow for unfettered rotation.
The friction ring causes the cone element to spin on rotation or roll on contact with the surface.
The foregoing and other objects, features and advantages of the present invention will become more apparent from the following description of preferred embodiments and accompanying drawings.

DETAILED DESCRIPTION OF THE DRAWINGS
The invention is principally described in FIG. 1 in terms of a generally circular leg ring (1) attached by elongated cord (2) at one end and a cone element (3) attached at the opposite end of elongated cord (2).
As illustrated in FIGS. 2 and 3, leg ring (1) is opened at one end for expanding to fit over a user's foot for operation. Leg ring (1) contains a snap clip (4) permanently attached to one end of leg ring (1) for communication with the second end of leg ring (1) to form a continuous ring, as illustrated in FIG. 4.
Leg ring (1), as illustrated in FIG. 3 consists of a cable retention channel (1a) around the outer circumference for retention of elongated cord (2). Elongated cord (2) at one end having a oval stop sleeve (5) to form a loop (2a) to close elongated cord (2) around leg ring (1). Oval stop sleeve (5) is positioned on elongated cord (2) at a length sufficient enough to permit opening of leg ring (1) when loop (2a) is around leg ring (1).
Leg ring (1) in the preferred embodiment, is constructed of extruded polypropylene or polyethylene plastic, but may be made of other suitable materials. Elongated cord (2) is constructed of vinyl or rubber coated steel in the preferred embodiment, but may be made of other suitable materials. Elongated cord (2) at the loop end (2) positioned within cable retention channel (1a) of leg ring (1) is capable of withstanding at least 50 pounds of force when in use.
Elongated cord (2) at the second end is connected to cone element (3). As illustrated in FIG. 5, cone element (3) comprises a top cone (6), a friction ring (7) and a base cup (10). Elongated cord (2) at the second end passes through an opening in the top of top cone (6) and is secured to top cone (6) by a cylindrical stop sleeve (9) and flange bushing (8) attached to the second end of elongated cord (2).
Flange bushing (8) minimizes friction between top cone (6) and allows free rotation of cone element (3).
