Resistive exercise apparatus

Abstract

An exercise apparatus is disclosed, which comprises a cushioned strap for providing a soft contact with a person's body when the exercise apparatus being used for a sit-on-chair exercise, and an elastic strip attached to ends of the cushioned strap to form a closed loop therewith, the elastic strip providing a resistive force to an exercising person when a portion of the elastic strip is restricted by a chair the exercising person sits on.

1 . An exercise apparatus comprising:
 a cushioned strap for providing a soft contact with a person's body when the exercise apparatus being used for a sit-on-chair exercise; and   an elastic strip attached to ends of the cushioned strap to form a closed loop therewith, the elastic strip providing a resistive force to an exercising person when a portion of the elastic strip is restricted by a chair the exercising person sits on.   
     
     
         2 . The exercise apparatus of  claim 1 , wherein the elastic strip is made of a rubber tube. 
     
     
         3 . The exercise apparatus of  claim 1 , wherein the elastic strip includes a length-adjustable portion for adjusting the total length of the closed loop. 
     
     
         4 . The exercise apparatus of  claim 3 , wherein the length-adjustable portion is made of a non-elastic fabric. 
     
     
         5 . The exercise apparatus of  claim 3 , wherein a length of the length-adjustable portion is adjustable by double folding a part or the whole length of the length-adjustable portion. 
     
     
         6 . The exercise apparatus of  claim 3 , wherein the elastic strip is divided into two separate elastic sections by the length-adjustable portion. 
     
     
         7 . The exercise apparatus of  claim 1 , wherein the elastic strip includes at least a hooking device for separating and rejoining two portions of the elastic strip. 
     
     
         8 . The exercise apparatus of  claim 1 , wherein the cushioned strap and the elastic strip are attached to each other by at least one hooking device, wherein when the hooking device is unhooked, the cushioned strap and the elastic strip are detached by the hooking device. 
     
     
         9 . The exercise apparatus of  claim 1 , wherein the portion of the elastic strip is restricted by a supporting pole of the chair. 
     
     
         10 . An exercise apparatus comprising:
 a cushioned strap for providing a soft contact with a person's body when the exercise apparatus is used for a sit-on-chair exercise;   a first and a second elastic strip attached to each end of the cushioned strap, respectively; and   a length-adjustable strip attached to both the first and the second elastic strip, the length-adjustable strip having a variable length,   wherein the cushioned strap, the first and second elastic strips and the length-adjustable strip form a closed loop, and the first and the second elastic strips provide a resistive force to an exercising person when the length-adjustable strip is restricted by a chair the exercising person sits on.   
     
     
         11 . The exercise apparatus of  claim 10 , wherein the first and second elastic strips are made of rubber tubes. 
     
     
         12 . The exercise apparatus of  claim 10 , wherein the length-adjustable strip is made of a non-elastic fabric and a length of the length-adjustable strip is adjustable by double folding a part or the whole length of the length-adjustable strip. 
     
     
         13 . The exercise apparatus of  claim 10 , wherein the first or the second elastic strip is attached to the length-adjustable strip by a hooking device wherein when the hooking device is unhooked, the first or the second elastic strip and the length-adjustable strip are detached by the hooking device. 
     
     
         14 . The exercise apparatus of  claim 10 , wherein the first or the second elastic strip is attached to the cushioned strap by one hooking device, wherein when the hooking device is unhooked, the first or the second elastic strip and the cushioned strap are detached by the hooking device. 
     
     
         15 . The exercise apparatus of  claim 10 , wherein the length-adjustable strip is restricted by a supporting pole of the chair. 
     
     
         16 . An exercise apparatus comprising:
 a cushioned strap for providing a soft contact with a person's body when the exercise apparatus is used for a sit-on-chair exercise;   a first and a second elastic strip attached to each end of the cushioned strap, respectively; and   a length-adjustable strip attached to both the first and the second elastic strip by at least one hooking device, the length-adjustable strip having a variable length,   wherein the cushioned strap, the first and second elastic strips, the hooking device and the length-adjustable strip form a closed loop, and the first and the second elastic strips provide a resistive force to an exercising person when the length-adjustable strip is restricted by a chair the exercising person sits on, and   wherein when the hooking device is unhooked, one end of the length-adjustable strip is detached from the first or the second elastic strip by the hooking device.   
     
     
         17 . The exercise apparatus of  claim 16 , wherein the first and second elastic strips are made of rubber tubes. 
     
     
         18 . The exercise apparatus of  claim 16 , wherein the length-adjustable strip is made of a non-elastic fabric and a length of the length-adjustable strip is adjustable by double folding a part or the whole length of the length-adjustable strip. 
     
     
         19 . The exercise apparatus of  claim 16 , wherein the length-adjustable strip is restricted by a supporting pole of the chair.
