Adjustable dumbbell system

Abstract

An adjustable dumbbell includes weight plates that are selectively connectable to a handle. Unselected weight plates are secured to a cradle. To secure the unselected weight plates to the cradle, a latch in the cradle is inserted into an engagement surface notch in the weight plate. The unselected weight plates are individually actuated based on which weight plates are selected and connected to the handle.

What is claimed is: 
     
         1 . A system for securing an adjustable dumbbell, comprising:
 a handle;   a plurality of weight plates selectively connectable to the handle;   a cradle configured to support the handle and the plurality of weight plates, the cradle including a latch to selectively retain a weight plate of the plurality of weight plates in the cradle;   a weight selection input configured to receive a set weight; and   a weight controller configured to selectively attach a combination of weight plates to the handle such that a dumbbell weight matches the set weight.   
     
     
         2 . The system of  claim 1 , wherein the weight selection input includes a voice recognition input. 
     
     
         3 . The system of  claim 1 , wherein the weight selection input includes one or more buttons. 
     
     
         4 . The system of  claim 1 , wherein the weight selection input includes a communication device configured to receive the set weight from a remote computing device. 
     
     
         5 . The system of  claim 1 , further comprising a display configured to display exercise information. 
     
     
         6 . The system of  claim 5 , wherein the display is a touch-sensitive display, and wherein the weight selection input includes one or more buttons on the touch-sensitive display. 
     
     
         7 . A system for securing an adjustable dumbbell, comprising:
 a handle;   a plurality of weight plates removably connected to the handle, each weight plate of the plurality of weight plates including a notch; and   a cradle including a plurality of latches configured to be selectively inserted into the notch located on each weight plate of the plurality of weight plates;   a weight selection input; and   a weight controller configured to activate one or more of the plurality of latches based on a set weight from the weight selection input.   
     
     
         8 . The system of  claim 7 , wherein the weight selection input includes a voice recognition input. 
     
     
         9 . The system of  claim 7 , wherein the weight selection input includes one or more buttons. 
     
     
         10 . The system of  claim 7 , wherein the weight selection input includes a communication device configured to receive the set weight from a remote computing device. 
     
     
         11 . The system of  claim 7 , further comprising a display configured to display exercise information. 
     
     
         12 . The system of  claim 11 , wherein the display is a touch-sensitive display, and wherein the weight selection input includes one or more buttons on the touch-sensitive display. 
     
     
         13 . The system of  claim 7 , wherein the latches are individually actuated. 
     
     
         14 . The system of  claim 7 , wherein the cradle includes a slot for each weight plate of the plurality of weight plates. 
     
     
         15 . A method for securing an adjustable dumbbell, comprising:
 receiving a set weight from a weight selection input;   based on the set weight, selectively connecting one or more selected weight plates of a plurality of weight plates to a handle to set the adjustable dumbbell to the set weight; and   securing an unselected weight plate of the plurality of weight plates to a cradle based on the selected weight plate connected to the handle.   
     
     
         16 . The method of  claim 15 , wherein the weight selection input is a voice recognition input, and wherein receiving the set weight from the weight selection input includes receiving a verbal command at the voice recognition input. 
     
     
         17 . The method of  claim 15 , wherein receiving the set weight includes receiving the set weight from a remote computing device. 
     
     
         18 . The method of  claim 15 , further comprising:
 selecting the selected weight plate; and   identifying the unselected weight plate as any weight plate of the plurality of weight plates that is not the selected weight plate.   
     
     
         19 . The method of  claim 15 , wherein securing the unselected weight plate includes inserting a latch into a notch in the unselected weight plate. 
     
     
         20 . The method of  claim 15 , wherein securing the unselected weight plate includes inserting a weight plate latch on the weight plate into a cradle notch on the cradle.
