Portable rowing/exercise device

Abstract

A portable rowing device that in one mode can be attached to a boat to provide a muscle exercise by propelling the boat in a forward facing direction through a body of water or in another mode can be attached to an exercise stand to provide the same muscle exercise without propelling the user through a body of water.

1 . A portable rowing device for use on either water or land comprising: 
 an attachment member;    a first gear having an arm attached thereto;    a second gear having a hand grip attached thereto: and    a base supporting said first gear and said second gear in rotational engagement with each other so that when the hand grip is pulled said first gear rotates in a first direction and said second gear rotates in an opposite direction.    
     
     
         2 . The portable rowing device of  claim 1  including: 
 a paddle on said arm;    a boat with said attaching member comprising a clamp secured to a first side of said boat so that a user can face in a forward direction as the paddle is pulled through a body of water; and a second portable rowing device secured to an opposite side of said boat.    
     
     
         3 . The portable rowing device of  claim 1  including: 
 a resistance member attached to said arm;    an exercise stand with said attachment member secured to a first side of said stand;    a second portable rowing device secured to an opposite side of said exercise stand with an arm of said second portable rowing device connected to said resistant member so that pulling a handle of said second portable rowing device and the handle of the first rowing device is resisted by the resistance member connected between the arm of said first portable rowing device and the arm of said second portable rowing device.    
     
     
         4 . The portable rowing device of  claim 1  wherein the base is pivotally mounted.  
     
     
         5 . The portable rowing device of  claim 1  wherein the first gear and the second gear have nylon teeth.  
     
     
         6 . The portable rowing device of  claim 1  wherein the first gear and the second gear are of the same diameter.  
     
     
         7 . The portable rowing device of  claim 1  wherein the arm includes an extension.  
     
     
         8 . The portable rowing device of  claim 1  wherein the attachment member includes a slot with a pressure plated therein for engagement with the side of a boat or the side of an exercise stand.  
     
     
         9 . The portable rowing device of  claim 1  wherein said first gear is repositionable with respect to said second gear to change the orientation of the arm with respect to the handle.  
     
     
         10 . The portable rowing device of  claim 1  wherein the arm includes a yoke with a pin for affixing said arm with respect to said first gear.  
     
     
         11 . The portable rowing device of  claim 10  wherein the arm includes a removable extension.  
     
     
         12 . The method of exercising muscles in different environments comprising: 
 attaching a portable rowing device to a gunwale of a boat and exercising a group of muscles by propelling the boat over the water,    removing the portable rowing device from the gunwale of the boat; and    attaching the portable rowing device to an exercise stand and exercising the group of muscles by rowing against a resistance connected to the portable rowing device.    
     
     
         13 . The method of  claim 12  including the step of mounting a hand grip arm on the portable rowing device and a work arm at an angle to each other.  
     
     
         14 . The method of  claim 12  wherein the step of attaching to the gunwale includes the step of clamping the portable rowing device to the gunwale.  
     
     
         15 . The method of  claim 12  wherein the step of attaching to the exercise stand including the step of clamping the portable rowing device to the exercise stand.  
     
     
         16 . The method of  claim 12  including the step of rotationally repositioning a gear member in the portable rowing device to change the direction of an arm extending from the portable rotating device.  
     
     
         17 . The method of  claim 12  including the step of removing a paddle on the portable rowing device.  
     
     
         18 . The method of  claim 12  including the step of changing the length of the arm in the portable rotating device by attaching a different length arm to a yoke member in the portable rowing device.  
     
     
         19 . A portable rowing device kit comprising: 
 a support for mounting the portable rowing device on either a gunwale of a boat or on an exercise stand;    a gear joined member having a work extension on one end and an extension for grasping on the other end with the gear joined member including spur gears in meshing engagement so that a rotational force on the end for grasping causes the extension on the work extension to rotate in a counter direction; and    a resistance member for securing to the work extension.    
     
     
         20 . The portable rowing device of  claim 19  wherein the spur gears comprises a non-metallic material to inhibit noise generation.
