Adjustable Plate Loaded Kettlebell

Abstract

An adjustable kettlebell has a series of plates in stacked relationship, a handle having a shaft passing through the weights and a retaining arrangement including a base plate engageable with the shaft for holding the plates together between the handle and the retaining arrangement. The invention is improved by a dome top having an outer surface formed with a locating pocket for receiving a portion of the handle in a snap fit therein, and an inner surface positioned upon an uppermost surface of the plates, and a reinforcement plate snap fit into a central hub of the base plate and engageable with a lower end of the shaft.

1 . An adjustable kettlebell comprising:
 a first set of vertically stacked plates having central bores registered with each other and fully exposed, outer peripheral edges aligned with each other;   a retaining plate positioned in stacked relationship against the lowermost one of the first set of plates and having a flat bottom and a central reinforcement plate with a central hole aligned with the central bores of the plates;   a dome top having an outer surface formed with a locating pocket therein, and a inner surface positioned upon an uppermost one of the first set of plates, the inner surface being recessed to receive a second set of vertically stacked plates having central bores registered with each other and with the central bores of the first set of plates;   a handle unit integrally formed by a rounded handle portion including lower ends joined to a handle base having an internally threaded shaft depending therefrom, the handle base being snap fit in the locating pocket of the dome top, and the shaft passing through the central bores of the first and second set of plates and contacting the reinforcement plate at a lower end of the shaft, and   a fastener passing through the central hole in the reinforcement plate and threaded into the lower end of the shaft for holding the first and second set of plates, the handle unit, the dome top and the retaining plate together.   
   
   
       2 . The adjustable kettlebell of  claim 1 , wherein the locating pocket is defined by a bottom wall, a pair of end walls and a pair of opposed side walls provided with retaining snaps thereon. 
   
   
       3 . The adjustable kettlebell of  claim 2 , wherein the handle base includes a U-shaped channel having front and back walls joined to a lower wall. 
   
   
       4 . The adjustable kettlebell of  claim 3 , wherein the handle base is received in the locating pocket such that upper edges of the front and back wall define snap edges that are engaged by the retaining snaps on the side walls of the locating pocket enabling the handle base to be frictionally retained in the locating pocket. 
   
   
       5 . The adjustable kettlebell of  claim 4 , wherein the lower wall of the handle base engages the bottom wall of the locating pocket. 
   
   
       6 . The adjustable kettlebell of  claim 1 , wherein the inner surface of the dome top includes a set of recesses of varying sizes for accommodating various sizes of the second set of plates. 
   
   
       7 . The adjustable kettlebell of  claim 1 , wherein certain of the first set of plates are solid weight plates and others of the first set of plates are plastic spacer plates. 
   
   
       8 . The adjustable kettlebell of  claim 7 , wherein each plastic spacer plate has a circular hub, a first inner ring surrounding the hub, a second inner ring surrounding the first inner ring, an outer peripheral edge surrounding the second inner ring and a series of radially extending walls connecting the hub, the inner rings and the peripheral edge. 
   
   
       9 . The adjustable kettlebell of  claim 1 , wherein the second set of plates are solid weight plates. 
   
   
       10 . The adjustable kettlebell of  claim 1 , wherein the retaining plate is a plastic plate having a central hub for receiving the reinforcement plate in a snap fit. 
   
   
       11 . The adjustable kettlebell of  claim 1 , wherein the handle unit, the weight plates, and the reinforcement plate and the fastener are all constructed of metal. 
   
   
       12 . In an adjustable kettlebell having a series of plates in stacked relationship, a handle having a shaft passing through the plates and a retaining arrangement including a base plate engageable with the shaft for holding the plates together between the handle and the retaining arrangement, the improvement comprising:
 a dome top having an outer surface formed with a locating pocket for receiving a portion of the handle in a snap fit therein, and an inner surface positioned upon an uppermost surface of the plates, and   a reinforcement plate snap fit into a central hub of the base plate and engageable with the lower end of the shaft.
