Air pressure seat lift

Abstract

An apparatus is provided for lowering and raising a person onto and up from a seated position particularly in conjunction with a commercial or residential commode. The apparatus is suitable as an attachable adaptation to existing commercial or residential commodes. The apparatus is attached directly to such a standard commode by using a pair of studs disposed to fit into holes through the commode that are used to attach commode seats. These studs are securely attached to the commode. Air pressure delivered from a remote source extends hydraulic cylinders in a manner to provide a user with the ability to be raised to a comfortable dismount position from a seat or to be reclined to a comfortable seated position on a commode. The individual will be moved down or up to a comfortable semi-standing position because a commode seat attached to the apparatus is disposed to be at an angled position to facilitate a user mounting or dismounting the apparatus.

1 . An apparatus for moving a commode seat, said apparatus comprising: 
 at least two pressure driven cylinders;    a commode crossbar attached by studs to a commode, said studs disposed in commode seat attachment holes extending through said commode;    a framework for interconnecting said commode crossbar to said cylinders;    said commode seat disposed from said framework;    at least two hose means for providing pressurized fluid from a fluid pressure source to said cylinders; and,    a means for exhausting pressurized fluid from said cylinders;    wherein when said cylinders are extended, said commode seat is positioned higher above said commode at a back portion of said commode than is said commode seat positioned above said commode at a front portion of said commode    
   
   
       2 . The apparatus of  claim 1  wherein said cylinders are provided with air pressure as the fluid media.  
   
   
       3 . The apparatus of  claim 1  wherein an user of said apparatus is moved about said commode at an essentially steady lowering and raising rate.  
   
   
       4 . The apparatus of  claim 1  wherein no electrical component is disposed in an area about said commode.  
   
   
       5 . The apparatus of  claim 1  wherein an user activates the apparatus with a remote control, hand switch, or foot operated initiation device.  
   
   
       6 . The apparatus of  claim 5  wherein said remote control, hand switch or foot operated device are air pressure operated devices.  
   
   
       7 . The apparatus of  claim 1 , further comprising at least two hinged joints disposed between said framework and said commode seat.  
   
   
       8 . The apparatus of  claim 1 , further comprising at least one fixed or removable and adjustable hand rail.
