BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an adjustable kettlebell device, and more particularly to an adjustable kettlebell device including an improved structure for allowing the weight elements to be easily and quickly and adjustably attached to or disengaged from the weight carrier and for allowing the adjustable kettlebell device to be easily operated by the users.

2. Description of the Prior Art

Typical kettlebells comprise a pair of oppositely-facing, generally frustum-shaped weight plates attached to a central plate with a first axis that is perpendicular to the axis of its handle, and the frustum-shaped weight plates may reduce the force of impact against the user's forearm during certain exercise movements.

For example, U.S. Pat. No. 7,182,715 to Anderson discloses one of the typical kettlebell exercise devices comprising a handle attached to a central plate and including places which can be held between the user's thumb and remaining fingers for improved control during other exercise movements.

However, the weight plates may not be easily adjusted and/or changeably attached to the central plate such that the weight of the typical kettlebell may not be changed or adjusted.

U.S. Pat. No. 7,563,208 to Chen, U.S. Pat. No. 7,731,640 to Chen, U.S. Pat. No. 7,811,212 to Chen, U.S. Pat. No. 7,883,452 to Chen, U.S. Pat. No. 8,784,280 to Krull, U.S. Pat. No. 8,858,406 to Klukas, U.S. Pat. No. 9,022,906 to Nelson, and U.S. Pat. No. 9,149,680 to Thompson et al. disclose several other typical adjustable kettlebell device apparatuses each comprising a series of plates in stacked relationship, a handle having a shaft passing through the weight plates and a retaining arrangement including a base engageable with the shaft for holding and securing the weight plates together between the handle and the retaining arrangement.

However, the base should be removed or disengaged from the shaft when engaging the weight plates onto the shaft or when disengaging the weight plates from the shaft, such that it takes time to attach or to disengage the weight plates from the shaft and such that the typical adjustable kettlebell device may not be easily operated by the users.
