Training device comprising an elastic resistance band

Abstract

A training device includes an elastic training band with an integrated strain sensor and an electronic measuring unit. The training device has a thickening formed at ends of the training band, which locally increases the cross-section of the training band.

         13 . A training device, comprising:
 an elastic training band with an integrated strain sensor; and   an electronic measuring unit,   wherein ends of the elastic training band include a thickening that locally enlarges a cross-section of the elastic training band.   
     
     
         14 . The training device of  claim 13 , wherein the thickening is made of a same base material as the elastic training band. 
     
     
         15 . The training device of  claim 13 , wherein the thickening is made of a different material than a base material of the elastic training band. 
     
     
         16 . The training device of  claim 15 , wherein the thickening comprises a tougher or harder material that is less stretchable than a material of the elastic training band. 
     
     
         17 . The training device of  claim 13 , wherein the thickening is integrally formed with a band portion of the elastic training band. 
     
     
         18 . The training device of  claim 13 , wherein at least one groove is formed in a housing of the electronic measuring unit into which the thickening is insertable. 
     
     
         19 . The training device of  claim 13 , wherein at least one rib is formed in a housing of the electronic measuring unit, wherein the at least one rib engages in a groove of the thickening. 
     
     
         20 . The training device of  claim 13 , wherein the thickening is electrically conductive and electrically connected to an electrically conductive core portion of the elastic training band. 
     
     
         21 . The training device of  claim 13 , wherein the thickening is directly contacted with a printed circuit board in a housing of the electronic measuring unit to establish an electrical connection. 
     
     
         22 . The training device of  claim 21 , wherein a portion of the electrically conductive thickening protrudes from the housing. 
     
     
         23 . The training device of  claim 13 , wherein the training band with the thickening is interchangeable with different housings or electronic measuring units. 
     
     
         24 . The training device of  claim 13 , wherein the elastic training band has a constriction or recess within the thickening to secure the elastic training band in a housing of the electronic measuring unit.
