Exercise machine

Abstract

An exercise machine has a small body. The body has a held portion for being held by users. The body is pivotally installed with a rope wheel for being wound by a rope. The rope wheel has a restoring means for restoring the rope to rewind the friction wheel. A friction means is coaxially installed with the rope wheel. A unidirectional bearing is used to connect the friction means and the axis of the wheel. The friction resisting force of the friction means is controlled by an adjust device. Thereby, as the rope is pulled, the friction means will be driven so as that the friction means will generate resisting force. Since the body is small, and the friction force between the friction wheel and the friction strip is not too large, the exercise machine is suitable for the rehabilitated patient and for general users engaged in gymnastic exercise.

What is claimed is:  
     
         1 . An exercise machine comprising a body, at least one tying strip, and a handle; wherein 
 one side of the body has a held portion for being held by a user; and one surface of the body has a concave back portion; the body has a receiving space; two sides of the body have respective ears; the receiving space of the body has a rope wheel; one end of a rope is wound around the rope wheel; another end of the rope is installed with a restoring means for driving the rope wheel to receive the pulled rope; a friction means is coaxially installed with the rope wheel; an unidirectional bearing is used to connect the friction means with an axis of the wheel; the friction resisting force of the friction means is controlled by an adjust device; thereby, as the rope is pulled, the friction means will be driven so that the friction means will generate a resisting force;    the tying strip passes through the ears of the body or is tied to a predetermined portion of the user directly; the tying strip has at least one buckling ring and each of two ends of the tying strip has a respective stud sticky strip; and    a fixing ring is connected to the fixing means at an outer side of the rope; thereby, the user can hole it for pulling the rope.    
     
     
         2 . The exercise machine as claimed in  claim 1 , wherein the restoring means is a spiral spring having an outer end and an inner end; the outer end of the spiral spring is directly hooked to the rope wheel and the inner end is hooked to a positioning pin of the boy.  
     
     
         3 . The exercise machine as claimed in  claim 1 , wherein the fixing means is a handle for being held by a user.  
     
     
         4 . The exercise machine as claimed in  claim 1 , wherein a guide means is installed in the body; the guide means is two guide wheels which are pivotally installed to the body below the cover; one end of the rope wind around the wheel passes through the two guide wheels and then the rope protrudes out of the via hole of the cover; thereby, when the rope is pulled or wound, by the guiding of the two guide wheels, the resisting force on the rope is reduced.  
     
     
         5 . The exercise machine as claimed in  claim 1 , wherein the friction means is a friction wheel and a periphery of the friction wheel is wound by a friction strip; the contact of the friction strip and an the friction wheel is controlled by the adjust device.  
     
     
         6 . The exercise machine as claimed in  claim 5 , wherein the adjust device is fixed to the body by a fixing frame; the fixing frame has a penetrated though hole; an adjust block is installed in the fixing frame; the adjust block has a threaded hole; the though hole of the fixing frame is passed through by a stud; one end of the stud is installed with a button; another end of the stud has a threaded section; the threaded section is screwed to a screw hole of the fixing frame; one end of the friction strip is firmly secured to the adjust block; by rotating the button to rotate the stud, the adjust block moves upwards or downwards in the fixing frame; the adjust block resists against the fixing frame so as not to rotate.
