Abstract

An exercise dumbbell includes a handle and weight plates maintained in spaced relationship relative thereto. At least one weight selector is movable into and out of engagement with different combinations of the weight plates to secure a desired amount of mass to the handle.

Claims

1. A method of adjusting weight resistance to exercise, comprising the steps of:

providing a weight lifting member having weight supports and defining a longitudinal axis;

providing weights sized and configured to be supported by the weight supports;

providing a weight selector having a first end portion sized and configured for insertion into less than all of the weights, and a relatively longer, second end portion sized and configured for insertion into a relatively greater number of the weights; and

alternatively inserting the first end portion and the second end portion into respective weights to secure desired combinations of the weights to the lifting member.

2. The method of claim 1, wherein the weight lifting member is provided with a handle, and a first group of the weight supports is disposed at one end of the handle, and a second group of the weight supports is disposed at an opposite end of the handle.

3. The method of claim 2, further comprising the step of providing a retainer on the weight lifting member to releasably retain either said end portion when the other said end portion is inserted into respective said weights.

4. The method of claim 2, wherein a first one of the weights is provided with an outwardly projecting tab that extends laterally in a first direction and defines a first hole, and a second one of the weights is provided with an outwardly projecting tab that extends laterally in an opposite, second direction and defines a second hole, and when the first one of the weights and the second one of the weights are axially aligned, each said tab is visible from each end of the longitudinal axis.

5. The method of claim 2, wherein a third one of the weights is provided with a first outwardly projecting tab that extends laterally in the first direction and defines a third hole that aligns with the first hole, and with a second outwardly projecting tab that extends laterally in the second direction and defines a fourth hole that aligns with the second hole, and only the second portion is long enough to enter both the third hole and the first hole and alternatively, to enter both the fourth hole and the second hole.

6. The method of claim 2, further comprising the step of providing a base to support the weights in a rest position.

7. An exercise dumbbell, comprising:

a handle assembly that defines a longitudinal axis;

weight supports secured to opposite ends of the handle assembly;

weights sized and configured to be supported by the weight supports, including a first weight having an outwardly projecting tab that extends laterally in a first direction and defines a first hole, and a second weight having an outwardly projecting tab that extends laterally in an opposite, second direction and defines a second hole, wherein when the first weight and the second weight are axially aligned, each said tab is visible from each end of the longitudinal axis; and

a weight selector configured for insertion through at least one of the weight supports, through the first hole, and alongside of the second weight, and alternatively, for insertion through at least one of the weight supports, alongside of the first weight, and through the second hole.

8. The exercise dumbbell of claim 7, further comprising a base configured to support the weights in a rest position.

9. The exercise dumbbell of claim 7, wherein the weight selector includes a first end portion and a relatively longer, second end portion that extends perpendicular to the first end portion.

10. The exercise dumbbell of claim 9, wherein the weights include a third weight having a first outwardly projecting tab that extends laterally in the first direction and defines a third hole that aligns with the first hole, and a second outwardly projecting tab that extends laterally in the second direction and defines a fourth hole that aligns with the second hole, and only the second portion is long enough to enter both the third hole and the first hole and alternatively, to enter both the fourth hole and the second hole.

11. The exercise dumbbell of claim 7, wherein at least two of the weight supports are configured to define a first passage that aligns with the first hole, and a second passage that aligns with the second hole, and a third passage that extends above the tab on the first weight and alongside of the second weight.

12. An adjustable weight exercise apparatus, comprising:

a weight lifting member that defines a longitudinal axis;

weight supports mounted on the weight lifting member;

weights sized and configured to be supported by the weight supports; and

a weight selector having a first end portion configured to select a first combination of the weights upon insertion into a passage defined by at least some of the weight supports, and having a second end portion configured to select a different, second combination of the weights upon insertion into the passage.

13. The exercise apparatus of claim 12, wherein the weight lifting member includes a handle, and a first group of the weight supports is disposed at one end of the handle, and a second group of the weight supports is disposed at an opposite end of the handle.

14. The exercise apparatus of claim 13, wherein the weight selector is L-shaped.

15. The exercise apparatus of claim 14, wherein the second end portion is longer than the first end portion.

16. The exercise apparatus of claim 13, wherein the passage extends through a first one of the weights and alongside of a second one of the weights.

17. The exercise apparatus of claim 16, wherein the passage extends through an outwardly projecting tab on the first one of the weights.

18. The exercise apparatus of claim 13, wherein the first end portion is configured to select a third combination of the weights upon insertion into a second passage defined by at least some of the weight supports, and the second end portion is configured to select a fourth combination of the weights upon insertion into the second passage.

19. The exercise apparatus of claim 13, wherein a first one of the weights defines a notch that aligns with the passage, and a second one of the weights defines a notch that aligns with the passage.

20. The exercise apparatus of claim 13, wherein the weight selector is a bar, and at least one notch in the bar has an axially measured width that is greater than an axially measured thickness of at least one of the weights.

21. The exercise apparatus of claim 13, further comprising a means for discouraging unintended removal of the weight selector from the passage.

22. The exercise apparatus of claim 21, wherein the means includes a clip that disposed adjacent one of the weight supports and configured to releasably retain either said end portion when the other said end portion is inserted into the passage.

23. An exercise dumbbell, comprising:

a handle that defines a longitudinal axis;

weight supports mounted on opposite ends of the handle;

weights sized and configured to be supported in respective, axially spaced positions defined by the weight supports; and

a weight selector having a first end portion configured to span a first group of the weights upon insertion into a passage defined by at least some of the weight supports, and a relatively longer, second end portion configured to span a second group of the weights upon insertion into a passage defined by at least some of the weight supports.

24. The exercise dumbbell of claim 23, further comprising a base configured to support the weights in a rest position.
