Collapsible Kettlebell

Abstract

A kettlebell having a housing which is configurable to an as-used configuration by filling a cavity in the housing with fill material. The kettlebell is returnable to a substantially planar stored configuration by emptying the cavity. The fill material can be varied from a group of different fill materials to vary the weight of the kettlebell in the as-used configuration. The housing has straps engaged to minimize twisting of the housing when the handle engaged to the housing is gripped by a user during exercise.

1 . A kettlebell device comprising:
 a collapsible housing having an interior cavity defined by a plurality of surrounding sidewalls;   said interior cavity configured for holding fill material, said fill material providing means for weighting said housing;   a handle engaged to a first side of said housing;   an aperture communicating with said cavity;   releasable means for closure of said fill aperture;   said housing collapsible to a substantially planar configuration when empty;   said cavity fillable through said aperture with said fill material, thereby configuring said housing to an as-used configuration; and   whereby said housing is configured to said planar configuration for storage by when said cavity is emptied of said fill material and configured to said as-used configuration when said cavity is filled with said fill material via said aperture to provide a weight to said housing.
