Adaptive resistance system for physical therapy and biomechanics training

Abstract

An adaptable resistance system with improved attachment structures may feature a clamp body with modular weight discs which may then be added to the clamp body. The clamp structure allows for the use of the training weight on any position on an element of sports equipment, such as a paddle, racket, or stick, as well as the use of multiple weights on the same piece of equipment. Locking mechanisms may be employed to further secure the clamp of the resistance system to the sports equipment. Modular weights allow for further customization as a user may remove all modular weights or selectively position a desired quantity on the resistance system.

What is claimed is: 
     
         1 . A resistance system comprising:
 a clamp, further comprising:
 two opposed jaws; 
 a locking mechanism to secure the jaws in a fixed position; and 
 a mount for at least one modular weight; 
   at least one modular weight, attachable to the mount and each weight also attachable to other weights by the same means for attachment as needed to attach to the mount; and   an item of sports equipment, upon which the clamp is affixed.   
     
     
         2 . The resistance system of  claim 1 , each weight further comprising:
 a boss on one surface of the weight;   an internal spring-actuated plunger with a portion extending outside a perimeter of the weight, the plunger also comprising a cam peg extending from a surface of the boss; and   a keyway on an opposite surface of the weight, made to interface with the boss of another weight and further comprising a J-hook cam track;   
       wherein, the boss is slid into the keyway and the cam peg interfaces with the J-hook cam track to secure weights together. 
     
     
         3 . The resistance system of  claim 2 , the mount further comprising a keyway and J-hook cam track. 
     
     
         4 . The resistance system of  claim 2 , the mount further comprising an boss and internal spring-actuated plunger with a cam peg extending from a surface of the boss. 
     
     
         5 . The resistance system of  claim 1 , the item of sports equipment being selected from the set of sports equipment consisting of: a racket, a paddle, a sport stick, and a cesta. 
     
     
         6 . A resistance device comprising:
 a clamp, further comprising:
 two opposed jaws; 
 a locking mechanism to secure the jaws in a fixed position; and 
 a mount for at least one modular weight; 
   at least one modular weight, attachable to the mount and each weight also attachable to other weights by the same means for attachment as needed to attach to the mount.   
     
     
         7 . The resistance device of  claim 6 , each weight further comprising:
 a boss on one surface of the weight;   an internal spring-actuated plunger with a portion extending outside a perimeter of the weight, the plunger also comprising a cam peg extending from a surface of the boss; and   a keyway on an opposite surface of the weight, made to interface with the boss of another weight and further comprising a J-hook cam track;   
       wherein, the boss is slid into the keyway and the cam peg interfaces with the J-hook cam track to secure weights together. 
     
     
         8 . The resistance device of  claim 7 , the mount further comprising a keyway and J-hook cam track. 
     
     
         9 . The resistance device of  claim 7 , the mount further comprising an boss and internal spring-actuated plunger with a cam peg extending from a surface of the boss.
