Range of motion control device

Abstract

A device for controlling range of motion of a stack of weights of a pin selectorized strength machine. First and second assemblies of the device are sized and dimensioned respectively for insertion into a hole of a weight selector stem of a pin selectorized strength machine, and for clamping to a guide rod. Methods of using the device.

1 . A device for controlling range of motion of a stack of weights of a pin selectorized strength machine, said device comprising
 a. a first assembly sized and dimensioned for laying on the top surface of a weight plate, said first assembly comprising a planar body having a thickness, a protrusion extending from one end of said planar body, said protrusion sized and dimensioned for insertion into a hole of a weight selector stem of a pin selectorized strength machine;   b. second assembly comprising a clamping mechanism sized and dimensioned for Attachment to a guide rod of a pin selectorized strength machine.   
     
     
         2 . A method for dosing a range of motion of a pin selectorized strength, said method comprising the steps of
 a. clamping a terminal limit assembly of a device for controlling range of motion on the guide rod thereby establishing a terminal limit of motion; and   b. insertion of the weight selector pin of a start limit assembly of said device into a hole of the weight selection stem mechanism, thereby limiting vertical movement of the weight selector stem mechanism, thereby establishing a start limit of motion,
 wherein said device comprises
 ii) a first assembly sized and dimensioned for laying on the top surface of a weight plate, said first assembly comprising a planar body having a thickness, a protrusion extending from one end of said planar body, said protrusion sized and dimensioned for insertion into a hole of a weight selector stem of a pin selectorized strength machine; and 
 (ii) a second assembly comprising a clamping mechanism sized and dimensioned for attachment to a guide rod of a pin selectorized strength machine. 
 
   
     
     
         3 . A pin selectorized strength machine comprising
 a. a first assembly sized and dimensioned for laying on the top surface of a weight plate, said first assembly comprising a planar body having a thickness, a protrusion extending from one end of said planar body, said protrusion sized and dimensioned for insertion into a hole of a weight selector stem mechanism;
 b. a second assembly comprising a clamping mechanism sized and dimensioned for attachment to a guide rod of said pin selectorized strength machine. 
   
     
     
         4 . A method for dosing a range of motion of a selected stack of weight plates of a pin selectorized strength machine, said method comprising the steps of:
 a. clamping a terminal limit assembly of a device for controlling range of motion on the guide rod thereby establishing a terminal limit of motion; and   b. insertion of the weight selector pin of a start limit assembly of said device into the hole of the weight selection stem mechanism, thereby establishing a start limit of motion.   
     
     
         5 . A kit comprising at least start assembly and a terminal assembly. 
     
     
         6 . The kit of  claim 5  further comprising one or more pin selectorized strength machines.
