Roll-able dumbbells
First Claim
1. A dumbbell, comprising:
- a handle defined by a pair of opposing ends;
a pair of end cap assemblies, each said assembly threadedly engaging one said end wherein each said end cap assembly comprises a locking cap, said locking cap threadedly engaging said handle, said locking cap comprising a central bore for accepting said handle end therein and an externally threaded portion surrounding and is spaced relation with said central bore; and
a pair of wheels, each said wheel slidingly engaging said handle generally adjacent to one said end, each said wheel comprising an outer ring defining a circular outer periphery and a central bore, said central bore defined by rolling means for permitting said wheel to rotate about said handle, and friction-creating means for resisting said rolling.

Abstract
Roll-able dumbbells are disclosed. An improved roll-able dumbbell utilizing gravitation and roll-resistance is presented having a handle and a plurality of circular weights attached to its ends. Regular dumbbells are generally held in hands and lifted up and down. The improved roll-able hand weights, in addition to providing benefits of a regular dumbbell, can be held and rolled against a variety of horizontal, slanted or vertical surfaces in a multitude of body positions. Each entire circular weight, its outer segments and/or the surface layer can rotate independently in respect to the handle. In addition, rotational resistance can be influenced by the user by tightening/loosening the end caps or other means. The total weight of the improved roll-able hand weights can also be adjusted by the user, who can select proper number and combination of individual components.
