Self-lowering toilet seat

Abstract

A device for automatically lowering a toilet seat. A lowering finger, in slidable connection with a cylinder like chamber, is utilized to create a vacuum in a chamber. The vacuum pressure varies from a metering valve system that thus propels the finger toward the seat in a controlled manner in order to affect a complete lowering of the seat.

1 . A seat lowering system comprising:
 an actuation mechanism;   a vacuum chamber;   a check valve;   an apparatus for creating an internal outward force;   a valve possessing an inlet;   wherein said actuation mechanism is in slidable communication with said chamber; wherein said actuation mechanism creates a vacuum in said air tight chamber and wherein said two way valve introduces air into said system to drive said actuation mechanism.   
   
   
       2 . The seat-lowering apparatus of  claim 1  wherein said actuation mechanism is manually operated. 
   
   
       3 . The seat-lowering apparatus of  claim 1  wherein said actuation mechanism is automatically operated. 
   
   
       4 . The seat-lowering apparatus of  claim 1  wherein an operational cycle commences when a user opens a cover. 
   
   
       5 . The seat-lowering apparatus of  claim 4  wherein said operational cycle is commenced without the knowledge of said user. 
   
   
       6 . The seat-lowering apparatus of  claim 5  wherein the duration of said operational cycle is adjustable. 
   
   
       7 . The seat-lowering apparatus of  claim 1  wherein said system is incorporated in presently configured toilet systems with no alteration of the original toilet bowl structure. 
   
   
       8 . The seat-lowering apparatus of  claim 1  wherein said apparatus for creating an internal outward force is spring tension. 
   
   
       9 . The seat-lowering apparatus of  claim 1  wherein said system operates silently. 
   
   
       10 . A seat-lowering system comprising:
 an actuation mechanism comprising an outwardly extending member in communication with a cylindrical member, said cylindrical member in slidable communication with a chamber, said chamber possessing a force generating mechanism, said chamber in communication with a valve, said valve in communication with the atmosphere, wherein a complete depression of said actuation mechanism against said force generating mechanism expels all air existing within said chamber through said check valve out to the atmosphere, to create a vacuum within said chamber and alter vacuum pressure through said valve said chamber and extend said actuation mechanism to lower a seat.   
   
   
       11 . The seat lowering system of  claim 10  wherein the variable vacuum pressure is controlled mechanically. 
   
   
       12 . The seat lowering system of  claim 11  wherein the variable vacuum pressure is controlled through adjustment of said valve. 
   
   
       13 . An automatic seat lowering system comprising:
 an actuation mechanism;   a cylindrical member;   a vacuum chamber;   a check valve;   an internal force generating mechanism; and,   a valve in communication with said atmosphere; wherein, upon complete depression of said actuation mechanism, the system utilizes variable vacuum pressure as a means of operation.   
   
   
       14 . The automatic seat lowering system of  claim 13  wherein an operational cycle includes vacuum development, equilibrium, and variable vacuum pressure.
