Measuring device

Abstract

A measuring device is provided for a training device that includes a weight, a wire that is connected to a first end of the weight, and a load generating unit configured to move the weight upward by moving a second end of the wire. The measuring device comprises a position detecting unit configured to detect the position of the weight, a load detecting unit configured to detect the load that is applied to the wire, and a display unit configured to display report data based on the detected data obtained by the position detecting unit and the load detecting unit. Each of the position detecting unit, the load detecting unit, and the display unit comprises an attachment portion, which is attachable to and detachable from the training device.

1 . A measuring device used in conjunction with a training device, the training device having a weight, an elongated member having a first end connected to the weight, and a load generating unit configured to move the weight upward by moving a second end of the elongated member, the measuring device comprising: 
 a position detecting unit configured to detect a position of the weight;    a load detecting unit configured to detect a load applied to the elongated member; and    a display unit configured to display report data based on the detection data obtained by the position detecting unit and the load detecting unit;    wherein each of the position detecting unit and the display unit comprises an attachment portion configured to releasably attach to the training device.    
   
   
       2 . The measuring apparatus according to  claim 1 , further comprising a reflecting unit configured to reflect light and arranged on an upper surface of the weight; and 
 the position detecting unit further comprises a light emitting portion configured to emit light toward the reflecting unit and a light receiving portion configured to receive light reflected by the reflecting unit.    
   
   
       3 . The measuring apparatus according to  claim 1 , wherein the load detecting unit is attached to the elongated member; and 
 the load detecting unit comprises a distortion receiving portion configured to receive tension applied to the elongated member, and a distortion measuring portion configured to measure distortion created therein by the tension received by the distortion receiving portion.    
   
   
       4 . The measuring apparatus according to  claim 1 , further comprising a data processing unit configured to perform data processing, and display the report data on the display unit based on the detection data obtained by the load detecting unit and the position detecting unit; 
 wherein the data processing unit comprises a position monitoring unit configured to monitor changes in the position of the weight based on the detection data detected by the position detecting unit, a load monitoring unit configured to monitor changes in the load based on the detection data detected by the load detecting unit, and a mass calculation unit configured to calculate the mass of the weight based on the changes in the position of the weight and the changes in the load.    
   
   
       5 . The measuring apparatus according to  claim 4 , wherein the mass calculation unit calculates the mass of the weight based on the load detected by the load monitoring unit, and displays the mass of the weight on the display unit when the position monitoring unit determines that the weight has stopped after movement of the weight.  
   
   
       6 . The measuring apparatus according to  claim 4 , wherein the data processing unit further comprises a mass storing unit configured to store mass data for the weight; and 
 the data mass calculation unit is configured to extract a value from the mass storing unit that is closest to the mass of the weight calculated based on the change in the position of the weight used and the load applied to the elongated member.    
   
   
       7 . The measuring apparatus according to  claim 6 , wherein the mass data comprises mass data for a single weight, and mass data for multiples of the single mass data.
