Abstract
An adjustable dumbbell (10) includes a central handle (22) which can be selectively connected to one or more outer weights (24) by means of a selector pin (26). The outer weights (24) are arranged in a nested symmetrical stack which provides for a compact construction and storage of the unused weights at the same time. The adjustable dumbbell (10) is also incrementally adjustable, and may be used either in conjunction with or as a substitute for a conventional weight stack in an exercise machine.
Claims10
An adjustable handheld dumbbell, which comprises:
- a handle;
- said handle including an opposing pair of longitudinally spaced-apart ends interconnected in fixed predetermined relationship, and a generally centrally disposed longitudinal grip secured between the ends;
- a plurality of weights, each weight including an opposing pair of end plates interconnected in fixed predetermined longitudinally spaced-apart relationship;
- said weights being configured to be disposed in a stacked and nested contacting arrangement, the ends of said handle being adapted for insertion into nested receipt between the end plates of the uppermost weight, with the end plates of each successive weight being spaced progressively further apart for nested receipt of the next adjacent upper weight;
- and
- a generally U-shaped pin for selectively connecting at least one of said weights to said handle for movement therewith in accordance with the desired exercise resistance, said pin including a pair of longitudinally spaced-apart laterally extending prongs adapted for receipt in a transverse direction through portions of said handle and said weights.

An adjustable handheld dumbbell, which comprises:
- a handle;
- said handle including a generally centrally disposed longitudinal grip and a pair of laterally spaced-apart parallel crosstubes extending between a pair of longitudinally spaced-apart ends interconnected in fixed predetermined relationship;
- said crosstubes being hollow with corresponding openings in one end of said handle;
- a sleeve of foam material surrounding the grip of said handle;
- a plurality of weights, each weight including an opposing pair of end plates interconnected in fixed predetermined longitudinally spaced-apart relationship;
- said weights being configured to be disposed in a stacked and nested contacting arrangement, the ends of said handle being adapted for insertion into nested receipt between the end plates of the uppermost weight, with the end plates of each successive weight being spaced progressively further outward for nested receipt of the next adjacent upper weight;
- a generally U-shaped pin for selectively connecting at least one of said weights to said handle for movement therewith in accordance with the exercise resistance desired, said pin including a pair of longitudinally spaced-apart laterally extending prongs adapted for receipt in a transverse direction through portions of said handle and said weights;
- a pair of generally cylindrical supplemental weights adapted for selective insertion through the end openings and into the crosstubes of said handle;
- and
- means mounted on said handle for selectively securing said supplemental weights within the crosstubes of said handle in order to provide intermediate adjustment of the exercise resistance desired.
