Multifunctional exercising apparatus

Abstract

An exercising apparatus has a cushion, a shaft assembly and two adjusting devices. The cushion has two connecting bases respectively mounted on the cushion. The shaft assembly pivotally connects with the cushion and has a lateral shaft and two supporting shafts. The supporting shafts are resilient and bendable and each has two ends and a connecting cylinder. One end connects with a corresponding connecting base of the cushion and the other end connects with the lateral shaft. The connecting cylinder is hollow, is formed on one end of the supporting shaft and connects with the connecting base. Each adjusting device selectively fastens securely or pivots the connecting cylinder on the connecting base. The exercising apparatus allows a user to exercise multiple parts of a user's body.

1 . An exercising apparatus comprising: 
 a cushion having 
 two sides; and  
 two connecting bases respectively mounted on the sides of the cushion and each connecting base having 
 an outside end having a central part and an outer edge;  
 a protrusion formed on the central part of the connecting base;  
 
   a shaft assembly pivotally connecting with the cushion and having 
 a lateral shaft having 
 two ends; and  
 two first connectors respectively mounted on the ends;  
 
 two supporting shafts being resilient and bendable, corresponding respectively to the connecting bases and each supporting shaft having 
 a proximal end connecting with a corresponding connecting base of the cushion;  
 a distal end connecting with a corresponding end of the lateral shaft;  
 a second connector mounted on the distal end of the supporting shaft and detachably connecting with a corresponding first connector of the lateral shaft; and  
 a connecting cylinder being hollow, being formed on the proximal end of the supporting shaft, rotatably connecting with the corresponding connecting base and engaging the protrusion of the corresponding connecting base and having 
 a through hole defined through the connecting cylinder, receiving the protrusion of the corresponding connecting base and having an outside open end and an inside open end; and  
 
 
 two adjusting devices respectively mounted to the connecting cylinders and each adjusting device connected the connecting cylinder of a corresponding supporting shaft with the protrusion of a corresponding connecting base.  
   
   
   
       2 . The exercising apparatus as claimed in  claim 1 , wherein each adjusting device has 
 an adjusting knob rotatably abutting the corresponding connecting cylinder; and    an extension rod being mounted on the adjusting knob and mounted through the through hole in the corresponding connecting cylinder to the protrusion of the corresponding connecting base.    
   
   
       3 . The exercising apparatus as claimed in  claim 1 , wherein each connecting base further has a wind of cogs formed around the outer edge of the end; and 
 each connecting cylinder further has a connecting ring formed on the inside open end of the through hole and having a wind of cogs corresponding to and selectively engaging with or disengaging from the wind of the cogs on a corresponding one of the connecting bases to adjust an angle between the cushion and the supporting shafts.    
   
   
       4 . The exercising apparatus as claimed in  claim 2 , wherein 
 each protrusion has 
 a central hole; and  
 a threaded sleeve being hollow, being securely mounted in central hole in the protrusion and having 
 an inner surface; and  
 an inner thread formed on the inner surface of the threaded sleeve;  
 
   the extension rod of each adjusting device has an outer surface and an outer thread formed on the outer surface of the end, corresponding with and screwed into the inner thread of a corresponding one of the threaded sleeves.    
   
   
       5 . The exercising apparatus as claimed in  claim 1 , wherein 
 each first connector is mounted on the lateral shaft and is a hook having 
 a narrowed opening having a width; and  
 an engaging hole communicating with the narrowed opening and having a dimension being greater than the width of the narrowed opening;  
   the second connector of each supporting shaft is mounted on the distal end of the corresponding supporting shaft opposite to the connecting cylinder and has 
 a bracket having 
 a bottom mounted on the distal end of the supporting shaft opposite to the connecting cylinder;  
 a top;  
 a recess communicating with the top and allowing a corresponding hook to mount in the recess;  
 a front wall formed in front of the recess and having 
 a front mounting hole formed through the front wall; and  
 a receiving ring formed on the front side, being around the front mounting hole of the front wall and having a non-circular inner edge; and  
 
 a rear wall formed behind the recess and having a rear mounting hole corresponding to the front mounting hole of the front wall;  
 
 a rod slidably extending through the front mounting hole of the front wall, the recess and the rear mounting hole of the rear wall of the bracket and having 
 a circular part selectively engaging with the engaging hole of a corresponding hook in the recess and having a diameter corresponding to the dimension of the engaging hole of the corresponding hook and being greater than the width of the narrowed opening of the corresponding hook;  
 a narrowed part formed on the circular part and engaging with the engaging hole and aligned with the narrowed opening of the corresponding hook in the recess when the circular part mounted outside the engaging hole and having a width being smaller than the width of the narrowed part of the hook;  
 a threaded protrusion protruding from the circular part of the rod and extending out of the rear mounting hole of the rear wall; and  
 a connecting protrusion protruding from the narrowed part of the rod;  
 
 a spring mounted around the rod and in the receiving ring;  
 a button mounted securely to the connecting protrusion, mounted in the receiving ring, allowing the spring to be mounted between the front wall and the button and having a non-circular outer edge corresponding to the non-circular inner edge of the receiving ring; and  
 a nut mounted around the threaded protrusion to maintain the rod in the bracket.
