Adjustable and portable handheld exerciser

Abstract

Disclosed is an adjustable and portable device for exercising the hand, fingers, wrist and forearm. Any number of mechanisms by which the device can be fully adjusted through a range of force settings allows both rehabilitation and strength training within the same unit. Using combinations of screws, springs, tension and fluids, this exercise device provides the user with versatility not offered by other products. The unit also provides a mechanism for adjustments in hand size to accommodate multiple users and ergonomic fit. In addition, the unit also has the benefit that it can be repaired or resistance increased when some of the key mechanisms are no longer functioning to the operators needs

1 . An adjustable handheld apparatus for the fingers, thumbs, hands, and wrists and forearm of a person, the apparatus comprising: 
 a) a body;    b) a trigger mechanism for transferring load to the internal mechanisms of the apparatus;    c) an interior assembly that can be used to generate resistance;    d) a handgrip to hold the unit;    e) an optional mechanism to allow removal and adjustment of the trigger;    f) a reservoir for housing fluids; and    g) one or more mechanisms on the assembly to adjust the force.    
   
   
       2 . The apparatus according to  claim 1 , in which the assembly uses an internal mechanism to generate mechanical or hydraulic impedance or load to the trigger to create resistance.  
   
   
       3 . The apparatus according to  claim 2 , further comprising a pump, a series of springs, and /or belts to generate variable resistance.  
   
   
       4 . The apparatus according to  claim 1 , in which the trigger can be removed to add various springs and/or that allows the trigger position to be changed.  
   
   
       5 . The apparatus according to  claim 4 , further comprising a plurality of springs of different compressive strength to vary resistance.  
   
   
       6 . The apparatus according to  claim 1 , comprising an assembly to allow the adjustment of fluid through the nozzle to vary the force.
