Description

    CROSS REFERENCE TO RELATED APPLICATIONS
  • This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application No. 61/331,603, filed May 5, 2010, and entitled “COLLAPSIBLE KETTLEBELL SYSTEM,” the disclosure of which is hereby incorporated by reference in its entirety.
  • BACKGROUND OF THE INVENTION
  • 1. Field of Invention
  • The invention relates generally to exercise weights and weight training, and more particularly, to a collapsible kettlebell system.
  • 2. Description of Related Art
  • In general, a kettlebell is a weight looking somewhat like a cannonball with a handle. Kettlebells are believed to have originated in Russia, where the first recorded mention of a kettlebell occurred in a Russian dictionary around the early 1700s. The Russian word for kettlebell is pronounced “girya” and the men who lifted these weights were known as “gireviks.” Historically, kettlebells were manufactured from cast iron. Today, many companies produce their own brands of kettlebells and kettlebell exercise programs. Some conventional kettlebells feature adjustable weights or are rubber coated to improve safety. While today, there are sizes that range from 5 lbs to 175 lbs, the traditional Russian kettlebell is usually one which weighs 1 Pood (roughly 16 kg or 35 lbs).
  • Unlike traditional dumbbells, a kettlebell's center of mass is extended beyond the hand. This allows for swing movements not possible with traditional dumbbells. Because more muscle groups are utilized in the swinging and movement of a kettlebell than during the lifting of dumbbells, a kettlebell workout is said to be more effective, and yields better results in less time. Because the center of mass on a kettlebell “swings,” micro-muscles are needed to balance a kettlebell, more so than a dumbbell. The existence of a handle allows for “release moves,” which are not available to a dumbbell.
  • U.S. Patent Application Publication Nos. 2010/0048362 to Liford et al., 2008/0081744 to Gormley, and 2009/0093348 to Wang disclose variations on the traditional kettlebell. However, these and other conventional kettlebell devices lack, among other things, a collapsible housing, i.e., bladder, for decreasing the size of the kettlebell when not in use and a handle that includes a cavity for receiving a fixed predetermined weight to increase the overall weight of the kettlebell.
  • SUMMARY OF THE INVENTION
  • The present invention overcomes these and other deficiencies of the prior art by providing a collapsible kettlebell system featuring a collapsible bladder like structure that can be filled by a liquid such as water, metal shavings or shot, sand and other appropriate substances.
