Abstract

An adjustable weight kettlebell includes a weight lifting member that houses a vertical stack of weights. Shelves on the housing portion of the weight lifting member are rotatable into and out of underlying engagement with respective weights.

Claims

1. An adjustable weight kettlebell, comprising:

a stack of weights, including an upper weight, and a lower weight, wherein the upper weight is configured to occupy an aligned position on top of the lower weight;

a weight lifting member configured to occupy an aligned position on top of the upper weight, wherein the weight lifting member includes (a) a handle; and

(b) a housing secured beneath the handle and defining a first shelf that is selectively rotatable beneath a portion of the upper weight, and a second shelf that is selectively rotatable beneath a portion of the lower weight; and

a latch movably mounted on the weight lifting member and selectively movable into and out of engagement with at least the upper weight;

wherein

when the weight lifting member occupies a first orientation relative to the weights, the weight lifting member is free to move upward relative to each said weight; and

when the weight lifting member occupies a second orientation relative to the weights, the first shelf underlies the upper weight, and only the upper weight is constrained to move upward together with the weight lifting member; and

when the weight lifting member occupies a third orientation relative to the weights, the second shelf underlies the lower weight, and each said weight is constrained to move upward together with the weight lifting member.

2. The adjustable weight kettlebell of claim 1, wherein rotation of the weight lifting member from the second orientation to the third orientation rotates the first shelf out from underlying engagement of the upper weight.

3. The adjustable weight kettlebell of claim 1, wherein a protuberance projects upward from the lower weight and into an opening in the upper weight to maintain a desired orientation between the lower weight and the upper weight.

4. The adjustable weight kettlebell of claim 1, wherein the first shelf is defined at least in part by a first slot in a sidewall of the housing, and the second shelf is defined at least in part by a second slot in the sidewall of the housing.

5. The adjustable weight kettlebell of claim 1, wherein the housing defines a third shelf that is selectively rotatable beneath a discrete portion of the upper weight, and a fourth shelf that is selectively rotatable beneath a discrete portion of the lower weight.

6. The adjustable weight kettlebell of claim 5, wherein the weight lifting member is rotatable about an axis of rotation, and the first shelf and the third shelf are diametrically opposed relative to the axis, and the second shelf and the fourth shelf are diametrically opposed relative to the axis.

7. The adjustable weight kettlebell of claim 1, wherein the upper weight is identical in size and configuration to the lower weight.

8. The adjustable weight kettlebell of claim 7, wherein said portion of the upper weight is proximate a lowermost surface of the upper weight, and said portion of the lower weight is proximate an uppermost surface of the lower weight.

9. An adjustable weight kettlebell, comprising:

a stack of weights, including an upper weight, and a lower weight, wherein the upper weight is configured to occupy an aligned position on top of the lower weight;

a weight lifting member configured to occupy an aligned position on top of the upper weight, wherein the weight lifting member includes (a) a handle; and

(b) a housing secured beneath the handle and defining a first shelf that is selectively rotatable beneath a portion of the upper weight, and a second shelf that is selectively rotatable beneath a portion of the lower weight; and

when the weight lifting member occupies a first orientation relative to the weights, the weight lifting member is free to move upward relative to each said weight, and said portion of the upper weight is hidden from above by the housing; and

when the weight lifting member occupies a second orientation relative to the weights, the first shelf underlies the upper weight, and only the upper weight is constrained to move upward together with the weight lifting member, and said portion of the upper weight is at least partly visible from above; and

when the weight lifting member occupies a third orientation relative to the weights, the second shelf underlies the lower weight, and each said weight is constrained to move upward together with the weight lifting member.

10. The adjustable weight kettlebell of claim 9, wherein said portion of the lower weight is at least partly visible from above when the weight lifting member occupies the third orientation relative to the weights, and said portion of the lower weight is hidden from above by the housing when the weight lifting member occupies the first orientation relative to the weights.

11. The adjustable weight kettlebell of claim 10, wherein said portion of the upper weight is a first color, and said portion of the lower weight is a second color.

12. The adjustable weight kettlebell of claim 11, wherein the first color appears on the weight lifting member to indicate a weight setting associated with engagement of the upper weight, and the second color appears on the weight lifting member to indicate a weight setting associated with engagement of the lower weight.

13. The adjustable weight kettlebell of claim 9, wherein the first shelf is defined at least in part by a slot in a sidewall of the housing.

14. An adjustable weight kettlebell, comprising:

a stack of weights, including a lower weight and an upper weight, wherein the upper weight is configured to occupy an aligned position on top of the lower weight;

a weight lifting member having (a) a handle, and (b) a housing secured beneath the handle, wherein the housing is sized and configured to accommodate the weights and selectively rotate out of and into underlying engagement of the weights; and

a latch movably mounted on the weight lifting member for movement into and out of engagement with at least the upper weight and biased to occupy a position that engages at least the upper weight to resist rotation of the housing relative to the weights when the weight lifting member occupies an aligned position on top of the upper weight.

15. The adjustable weight kettlebell of claim 14, wherein a portion of the upper weight projects into a first slot in the housing when the weight lifting member is rotated in a first direction relative to the weights, and a portion of the lower weight projects into a second slot in the housing when the weight lifting member is rotated in an opposite, second direction relative to the weights.

16. The adjustable weight kettlebell of claim 15, wherein said portion of the upper weight is a first color, and said portion of the lower weight is a second color.

17. The adjustable weight kettlebell of claim 16, wherein the first color is visible from above when said portion of the upper weight projects into the first slot in the housing, and the second color is visible from above when said portion of the lower weight projects into the second slot in the housing.

18. The adjustable weight kettlebell of claim 16, wherein the first color appears on the weight lifting member to indicate a weight setting associated with engagement of the upper weight, and the second color appears on the weight lifting member to indicate a weight setting associated with engagement of the lower weight.
