Running machine with a pulling rope

Abstract

A running machine with a pulling rope has a treadmill and a rope assembly. The rope assembly is mounted on the treadmill and has a housing and at least one rope set mounted in the housing. Each of the at least one rope set has a pulling rope. An end of the pulling rope is secured in the housing. Another end of the pulling rope protrudes out of the housing and is connected to a grip. The pulling rope is resiliently retracted toward the housing. When a user is exercising on the running machine, one of two hands of the user holds the at least one grip and swings naturally to pull the pulling rope. Resilient restoring force of the pulling ropes provides resistance to the user pulling the pulling ropes. Accordingly, an upper body and a lower body of the user can be trained simultaneously.

What is claimed is: 
     
         1 . A running machine comprising:
 a treadmill having
 a moving platform having a front end; and 
 an upright support mounted on the front end of the moving platform and protruding up from the moving platform, and the upright support having an upper end; and 
   a rope assembly mounted on the upper end of the upright support and having
 a housing securely mounted on the upper end of the upright support; and 
 at least one rope set mounted in the housing, each of the at least one rope set having
 a pulling rope mounted through the housing, resiliently retracted toward the housing, and having
 a connecting end mounted and secured in the housing; and 
 a pulling end protruding out of the housing; and 
 
 a grip connected to the pulling end of the pulling rope. 
 
   
     
     
         2 . The running machine as claimed in  claim 1 , wherein
 the housing of the rope assembly has
 a rear sidewall; and 
 at least one mounting recess formed in the rear sidewall of the housing; 
   the pulling rope of each of the at least one rope set is mounted through a corresponding one of the at least one mounting recess of the housing; and   the grip of each of the at least one rope set is detachably mounted in a corresponding one of the at least one mounting recess of the housing.   
     
     
         3 . The running machine as claimed in  claim 2 , wherein
 the housing of the rope assembly has two mounting recesses separately formed in the rear sidewall of the housing;   the rope assembly has two rope sets;   the two pulling ropes of the rope sets are respectively mounted through the mounting recesses of the housing; and   the two grips of the rope sets are respectively mounted detachably in the mounting recesses of the housing.   
     
     
         4 . The running machine as claimed in  claim 1 , wherein the pulling rope of each of the at least one rope set is resilient. 
     
     
         5 . The running machine as claimed in  claim 2 , wherein the pulling rope of each of the at least one rope set is resilient. 
     
     
         6 . The running machine as claimed in  claim 3 , wherein the pulling rope of each rope set is resilient. 
     
     
         7 . The running machine as claimed in  claim 1 , wherein
 each of the at least one rope set further has
 a pivot shaft rotatably mounted in the housing; 
 a rope reel securely mounted around the pivot shaft and being coaxial with the pivot shaft, and the rope reel having
 a peripheral surface; and 
 a reel recess formed in the peripheral surface of the rope reel; and 
 
 a restoring element being resilient and having two ends respectively connected to the rope reel and the housing; 
   the pulling rope of each of the at least one rope set is mounted around the rope reel in the reel recess; and   the connecting end of the pulling rope of each of the at least one rope set is securely connected to the rope reel.   
     
     
         8 . The running machine as claimed in  claim 2 , wherein
 each of the at least one rope set further has
 a pivot shaft rotatably mounted in the housing; 
 a rope reel securely mounted around the pivot shaft and being coaxial with the pivot shaft, and the rope reel having
 a peripheral surface; and 
 a reel recess formed in the peripheral surface of the rope reel; and 
 
 a restoring element being resilient and having two ends respectively connected to the rope reel and the housing; 
   the pulling rope of each of the at least one rope set is mounted around the rope reel in the reel recess; and   the connecting end of the pulling rope of each of the at least one rope set is securely connected to the rope reel.   
     
     
         9 . The running machine as claimed in  claim 3 , wherein
 each rope set further has
 a pivot shaft rotatably mounted in the housing; 
 a rope reel securely mounted around the pivot shaft and being coaxial with the pivot shaft, and the rope reel having
 a peripheral surface; and 
 a reel recess formed in the peripheral surface of the rope reel; and 
 
 a restoring element being resilient and having two ends respectively connected to the rope reel and the housing; 
   the pulling rope of each rope set is mounted around the rope reel in the reel recess; and   the connecting end of the pulling rope of each rope set is securely connected to the rope reel.   
     
     
         10 . The running machine as claimed in  claim 7 , wherein the restoring element of each of the at least one rope set is a volute spring. 
     
     
         11 . The running machine as claimed in  claim 8 , wherein the restoring element of each of the at least one rope set is a volute spring. 
     
     
         12 . The running machine as claimed in  claim 9 , wherein the restoring element of each rope set is a volute spring.
