Benefits of technology

[0005]The invention consists of a set of dynamic-free-weights, each weight having a shape of a theta. The free-weight curves along at least one axis so that the weight is evenly distributed al...

Problems solved by technology

However, all of the preceding patents lack key design features that place an increased stress on joints in the hand, wrist, forearm, and shoulder.
The typical cylindrical shape, as in the above patents, do not allow for a forearm to be in a relaxed position wh...

Embodiment Construction

[0006]The weights consist in a hollow-cylinder with an inner handle. The measurements of the handle and the height of the hollow-cylinder generally remain uniform throughout the set insuring consistency in shapes, esthetic appearance, functionality and feeling when held in the hand.

[0007]The handle has an elliptical shape that allows stronger grip. The rubber coat creates a frictional force that helps securing the grip during movements preventing shifting of the hand and consequential loss of the stabilizing effects of the circular shape and purpose of the present invention.

[0008]The theta shape distributes the weight evenly around the center of mass (the palm of the hand) decreasing drastically the torque and momentum, forces that traditional dumbbells and even more kettle bells easily cause. Along the circular portion of the weight are two perimeter sections that extend outward from the handle. Each curving perimeter section curves along at least one axis of the structure. The ang...

Abstract

The invention consists in a set of dynamic-free-weights with a theta shape ranging from 3 lbs to 20 lbs. The shape and weights are optimal to perform dynamic-functional movements safely and efficiently, the appearance of the set is refreshing, colorful and innovating.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Patent Application No. 61 / 705,897, filed on Sep. 26, 2012.FIELD OF THE INVENTION[0002]The present invention relates to dynamic-free-weights. The weights present an asymmetrical “theta” that provides maximum wrist stability and balance specifically appropriate for dynamic / functional movements. Weights are designed to use in a set.BACKGROUND OF THE INVENTION[0003]The idea of a balanced hand weight appeared in February 2001 (U.S. Pat. No. D438,265 S) and in October 2003 (U.S. Pat. No. D480,438). The latest patent was issued to Paul J. Fenelon in February 2011 (U.S. Pat. No. 7,878,952 B2). These patents use a cylindrical model to design the free-weights. In order to reduce stress on the user, designers have turned to using a cylindrical shape. A comparison between the traditional dumbbell and the cylindrical weight shows the possibility of a reduction of the torque along the forearm axis. T...
