Adjustable-weight fitness device

Abstract

Various embodiments of adjustable-weight fitness devices are described. A adjustable-weight fitness device may be implemented as a fitness hammer having an elongated handle coupled to head at a distal end of the handle. Weight plates are placed over the handle and rest on or inside the head. The resistance provided by the fitness hammer is adjustable, depending on how many weight plates are installed. The adjustable-weight fitness device may be implemented as a fitness kettle bell having a hand grip releasably coupled to a sleeve that is in turn coupled to a bottom plate of the head. The hand grip is removed in order to install one or more weight plates over the sleeve and then the hand grip is secured to the sleeve to form a functional kettle bell.

         3 . The adjustable-weight fitness device of  claim 1 , wherein the adjustable fitness device comprises a fitness hammer, the head comprises a bottom plate coupled to the first end of the handle at substantially a center of the bottom plate. 
     
     
         4 . The adjustable-weight fitness device of  claim 1 , further comprising:
 a sleeve extending substantially perpendicularly from the bottom plate concentrically located at substantially a center of the bottom plate, the sleeve comprising a hollow cylinder comprising an inner diameter substantially matching an outer diameter of the handle;   wherein a portion of the handle proximate to the first end is retained inside the hollow cylinder.   
     
     
         5 . The adjustable-weight fitness device of  claim 1 , wherein:
 the handle comprises a rigid, elongated member;   the head comprises a bottom plate coupled to the first end of the handle at substantially a center of the bottom plate and the head further comprises a concentric vertical wall extending substantially perpendicularly from an outer perimeter of the bottom plate towards the handle, the bottom plate, the sleeve and the concentric vertical wall forming a concentric void for retaining the one or more removable weights.   
     
     
         6 . The adjustable-weight fitness device of  claim 5 , wherein a height of the concentric vertical wall is substantially a multiple of a thickness of each of the one or more weights. 
     
     
         7 . The adjustable-weight fitness device of  claim 5 , wherein the sleeve further comprises an outer diameter substantially matching an inside diameter of the mounting hole of each of the one or more weights. 
     
     
         8 . The adjustable-weight fitness device of  claim 5 , wherein the sleeve further comprises a length greater than a height of the concentric vertical wall. 
     
     
         9 . The adjustable-weight fitness device of  claim 1 , further comprising:
 an aperture formed through a center of the head; and   a fastener mounted through the aperture and into the first end of the handle for securing the handle to the head.   
     
     
         10 . The adjustable-weight fitness device of  claim 1 , wherein the handle comprises a first portion of a reciprocal fastener and the adjustable fitness device further comprises:
 a cylinder extending substantially perpendicularly from the bottom plate concentrically located at substantially a center of the bottom plate, the cylinder comprising a second portion of the reciprocal fastener extending substantially perpendicularly from a top surface of the cylinder;   wherein the handle and the post are mechanically coupled together when the first portion and the second portion of the reciprocal fastener are joined.   
     
     
         11 . The adjustable-weight fitness device of  claim 1 , wherein the adjustable-weight fitness device comprises a kettle bell, wherein the handle comprises a hand grip releasably coupled to a sleeve, the sleeve coupled to the head, the adjustable-weight fitness device further comprising:
 the one or more removable weights each comprising a mounting hole formed therethrough, a first of the one or more removable weights resting against the head and mounted over the sleeve through the mounting hole in each of the one or more weights.   
     
     
         12 . The adjustable-weight fitness device of  claim 11 , wherein the head comprises a bottom plate coupled to sleeve at substantially a center of the bottom plate. 
     
     
         13 . The adjustable-weight fitness device of  claim 12 , wherein a first end of the sleeve comprises means for releasably coupling the hand grip to the first end of the sleeve, and the hand grip comprises a reciprocal means for releasably coupling the hand grip to the first end of the sleeve. 
     
     
         14 . The adjustable-weight fitness device of  claim 13 , wherein the bottom plate comprises:
 a concentric vertical wall extending substantially perpendicularly from an outer perimeter of the bottom plate towards the hand grip, wherein the bottom plate, the sleeve and the concentric vertical wall form a concentric void for retaining the one or more removable weights.   
     
     
         15 . The adjustable-weight fitness device of  claim 14 , wherein a height of the concentric vertical wall is substantially a multiple of a thickness of each of the one or more weights. 
     
     
         16 . The adjustable-weight fitness device of  claim 11 , wherein the sleeve comprises an outer diameter substantially matching an inside diameter of the mounting hole of each of the one or more weights. 
     
     
         17 . The adjustable-weight fitness device of  claim 11 , further comprising:
 an aperture formed through a center of the head; and   a fastener mounted through the aperture and into the second end of the sleeve for securing the sleeve to the head.   
     
     
         18 . A method for converting a fitness hammer into a fitness kettle bell, comprising:
 removing a longitudinal handle of the fitness hammer from a head of the fitness hammer; and   installing a closed-loop hand grip onto the head.   
     
     
         19 . The method of  claim 18 , wherein:
 installing the closed-loop handgrip comprises removably attaching the closed-loop handgrip to a cylinder extending from a bottom plate of the head.   
     
     
         20 . The method of  claim 19 , wherein the cylinder comprises a diameter substantially matching a diameter of a mounting hole of a weight plate used in conjunction with the fitness hammer and the fitness kettle bell.
