Abstract

Claims (18)

1. A dumbbell assembly, comprising:

a cradle shaped to receive a first dumbbell having a first weight set and a second dumbbell having a second weight set;

a first selector integrated into the first dumbbell and arranged to selectively connect or disconnect one or a plurality of weights of the first weight set to the first dumbbell;

a second selector integrated into the second dumbbell and arranged to selectively connect or disconnect one or a plurality of weights of the second weight set to the second dumbbell;

a selection mechanism incorporated in the cradle, wherein the selection mechanism is in communication with both the first selector and the second selector;

an input mechanism in communication with the selection mechanism; and

wherein a longitudinal axis of the first selector is coaxial with a central axis of a first handle of the first dumbbell.

2. The dumbbell assembly of claim 1 , wherein the input mechanism is incorporated into the cradle.

3. The dumbbell assembly of claim 1 , wherein the input mechanism comprises a rotary dial.

4. The dumbbell assembly of claim 3 , wherein the selection mechanism comprises a rotary gear positioned to rotate the first selector and the second selector simultaneously as the rotary dial is rotated.

5. The dumbbell assembly of claim 1 , further comprising a motor in communication with the input mechanism, wherein the motor selectively actuates the selection mechanism.

6. The dumbbell assembly of claim 1 , wherein the first selector is aligned with a first support structure of the first dumbbell and the second selector is aligned with a second support structure of the second dumbbell.

7. The dumbbell assembly of claim 1 , wherein the first selector includes a first cam mechanism arranged to selectively connect or disconnect one or a plurality of weights of the first weight set to the first dumbbell and the second selector includes a second cam mechanism arranged to selectively connect or disconnect one or a plurality of weights of the second weight set to the second dumbbell.

8. The dumbbell assembly of claim 1 , wherein the first selector comprises a first rod configured to disconnect a first weight of the first weight set from the first dumbbell and the second selector comprises a second rod configured to disconnect a second weight of the second weight set from the second dumbbell.

9. The dumbbell assembly of claim 1 , wherein the first selector and the second selector comprise rotary selectors.

10. The dumbbell assembly of claim 1 , wherein the first selector is in communication with a first interlocking pin positioned to interlock a first subset of the first weight set with the first dumbbell based on a first rotary orientation of the first selector and the second selector is in communication with a second interlocking pin positioned to interlock a first subset of the second weight set with the second dumbbell based on a first rotary orientation of the second selector.

11. The dumbbell assembly of claim 10 , wherein the first selector comprises a groove shaped to allow the first interlocking pin to retract and release the first subset of the first weight set from the first dumbbell based on a second rotary orientation of the first selector.

12. The dumbbell assembly of claim 11 , wherein the second selector comprises a groove shaped to allow the second interlocking pin to retract and release the first second subset of the second weight set from the second dumbbell based on a second rotary orientation of the second selector.
