Abstract

This invention relates to a system for facilitating an automatic urinal toilet flushing comprising: a pipe (P) having an intermediate enlarged inner diameter area, said pipe comprising: first portion P 1 having a first diameter d 1 ; second portion P 2 having a second diameter d 2 ; a third portion P 3 having a third diameter d 3 ; wherein the first, the second and the third portions are sequential and the diameter d 2 is greater than diameter d 1 and diameter d 3 ; a tapered forth portion P 4 connecting the first portion P 1 to the second portion P 2 ; and a tapered fifth portion P 5 connecting the second portion P 2 to the third portion P 3 ; a valve mechanism located within the pipe (P), the said valve mechanism comprising an inlet dual valve ( 1 ), an outlet dual valve ( 2 ) and a connecting rod connecting the inlet dual valve ( 1 ) and outlet dual valve ( 2 ); and an actuating mechanism that gets automatically actuated and upon actuation, operates the valve mechanism to perform a flushing operation.

First claim

We claim:

1. A system for facilitating an automatic urinal toilet flushing comprising:
a pipe (P) connected to a water reservoir on a first end and a urinal toilet at a second end and having an intermediate enlarged inner diameter area, said pipe comprising:
a first portion P 1 having a first diameter d 1 ;
a second portion P 2 having a second diameter d 2 ;
a third portion P 3 having a third diameter d 3 ; wherein the first, the second and the third portions are sequential and the diameter d 2 is greater than diameter d 1 and diameter d 3 ;
a tapered fourth portion P 4 connecting the first portion P 1 to the second portion P 2 ; and
a tapered fifth portion P 5 connecting the second portion P 2 to the third portion P 3 ;

a valve mechanism located within the pipe (P), the said valve mechanism comprising an inlet dual valve ( 1 ), an outlet dual valve ( 2 ) and a connecting rod connecting the inlet dual valve ( 1 ) and outlet dual valve ( 2 ); and
an actuating mechanism for operating the valve mechanism to perform a flushing operation, the actuating mechanism comprising:
a mechanical platform ( 10 ) mounted upon a base in a movable manner, and separated from the base by a set of resilient means, such that the mechanical platform moves closer to the base under weight of person; and
a connecting cable ( 8 ) adapted to connect both the dual-valve with the mechanical platform ( 10 ).

2. The system for facilitating automatic urinal toilet flushing as claimed in claim 1 , wherein the actuating mechanism operates the inlet and outlet dual valves such that when the inlet dual valve is in a closed position, the outlet dual valve is maintained in an open position and vice-versa.

3. The system for facilitating automatic urinal toilet flushing as claimed in claim 2 , wherein in the closed position the first and second portion of the inlet dual valve co-operates with the first and the fourth portions P 1 and P 4 of the pipe, respectively.

4. The system for facilitating automatic urinal toilet flushing as claimed in claim 2 , wherein in the closed position the first and second portion of the outlet dual valve co-operates with the third and the fifth portions P 3 and P 5 of the pipe, respectively.

5. The system for facilitating automatic urinal toilet flushing as claimed in claim 1 , wherein the inlet dual valve comprises a first and a second portion, with the second portion comprising a tapered diameter.

6. The system for facilitating automatic urinal toilet flushing as claimed in claim 5 , wherein the inlet dual valve comprises a resilient sealing means disposed between the first and a second portion.

7. The system for facilitating automatic urinal toilet flushing as claimed in claim 1 , wherein the outlet dual valve comprises a first and a second portion, with the second portion comprising a tapered diameter.

8. The system for facilitating automatic urinal toilet flushing as claimed in claim 7 , wherein the outlet dual valve comprises a resilient sealing means disposed between the first and a second portion.

9. The system for facilitating automatic urinal toilet flushing as claimed in claim 1 , wherein the base is provided with a set of motion limiting structures so as to maintain a minimum distance between the base and the mechanical platform.

10. The system for facilitating automatic urinal toilet flushing as claimed in claim 1 , further comprising a resilient means ( 7 ) adapted to retain in its normal position the inlet dual-valve in the closed position and the outlet dual-valve in the open position.

11. The system for facilitating automatic urinal toilet flushing as claimed in claim 1 , wherein the third portion P 3 of the pipe is adopted to hold a predetermined quantity of water therein for flushing purposes.
