Abstract

A mechanic apparatus (1) applied to the internal bottom seat (2) toilets (B) without a siphon, supplied with water from hydraulic pipes (C) or cisterns (R), which, after the discharge caused by the mechanism, flows to the sewer system (E); the apparatus (1) comprises a dam (3) that embodies externally the seat (2) and is fixed resting by latches (4), which are released by external release driving means (5), said dam (3) presents a hinge point (6) with a corresponding counterweight (7); the dam (3), when locked and resting, can keep approximately 2 litres of water inside the toilet; when the latch (4) is released, the dam hinges up discharging the water and the sewage straight into the sewer piping (T), goes back to its resting point by means of the counterweight (7), and locks again at the ideal position. In this moment, approximately 2 liters of water from the pipe (C) or cistern (R) are liberated, refilling the toilet for new use.

Description

"MECHANICAL APPARATUS APPLIED TO THE TOILET FLUSH".

The present invention relates to a new mechanical apparatus applied to the toilet flush, more particularly, a device likely to substitute the traditional existing mechanisms with a system intended to diminish the waste of water caused by the common flush.

As widely known, one of the most serious worldwide concerns relates to the careless consumption of fresh water, so rare and necessary to the human being.

Current studies are alarming about the near future and, thus, everyone should be concerned about saving water or developing means to allow equipment that use water as an active element to be as economic as possible.

For instance, it is known that washing a toilet piece after use requires mechanisms responsible for liberating a certain load of water, being the most usual ones known . as: a) manual or pedal drive valve, which liberates over 5 liters of water held in the hydraulic pipes; or b) overhead cistern or attached cistern, both of which usually store 5 liters of water in average, which are totally discharged into the toilet and lost in the sewer systems. Toilets are designed in ceramic material and employ a siphon system permanently filled with water, which is responsible for the non-reflux of gases and odors from the sewer piping. For this reason, the amount of water described above is required to perform the toilet flush, because such an amount fully discharged at once should be able to move the water standing in the siphon, pushing it to the sewer piping and taking the deposited sewage with it.

This way, we can understand that the system proposed until the current days is based on preventing the reflux of gases and odors from the sewer piping by means of a siphon sealed with water, which should be pushed by, at least, 5 liters of water.

The Applicant, intending to develop a new toilet cleaning system with a minimum waste of water and cooperating with the economy and preservation of the national reservoirs, has developed the present mechanical apparatus that simplifies the production of toilet molds by discarding the use of a siphon and reduces the amount of water required to approximately 2 liters.

Such a reduction may seem insignificant when related to a few liters, but it means a reduction of approximately 60% in the general use.

This way, discarding the siphon, a hinged dam mechanism was designed to store the minimum of 1 liter of water inside the toilet, so as to block the reflux of gases and odors from the piping system.

Said dam system comprises a hinged chest in an appropriate bearing opposed to a corresponding weight, which, when activated by a manual or automatic latch to release the flush, it can hinge such dam from its resting position and timely discharge the water to the sewer, causing the dam to return at the same time as it liberates the replenishing valve provided in the water supply pipe or in the overhead cistern, pointing out that it uses only 2 liters of water to replenish for the next flush.

In order to supplement the present description and offer a better understanding of the characteristics of this invention and, in accordance with a preferential practical realization of it, the attached set of drawings, without limitations and as an exemplification, represents the following. figure 1 is a side view in schematic section illustrating the apparatus in resting position applied to a toilet with no siphon and with water supply done by a pipe or a cistern; and figure 2 illustrates the same apparatus in flush position.

According to the illustrated drawings, the present invention relates to a new "MECHANIC APPARATUS APPLIED TO THE TOILET FLUSH", a mechanic apparatus (1 ) applied to the internal bottom seat (2) of toilets (B) without a siphon, supplied with water from hydraulic pipes (C) or cisterns (R), which, after the discharged caused by the mechanism, flows to the sewer system (E).

According to the present invention, the apparatus

(1 ) comprises a dam (3), which embodies externally the seat (2) and is presented fixed and resting (figure 1 ) by means of locking devices (4), such as latches, which are released by an external drive (5), such as chains or release buttons, pointing out that said dam (3) contains a hinge point (6) with a corresponding counterweight (7).

Said dam (3), when locked and resting, can keep approximately 2 liters of water inside the toilet.

When the latch (4) is released, the dam hinges up discharging the water and the sewage straight into the sewer piping (T), goes back to its resting point by means of the counterweight (7), and locks again at the ideal position. In this moment, approximately 2 liters of water from the pipe (C) or cistern (R) are liberated, refilling the toilet for new use.

The innovative apparatus (1) prevents the reflux of gases from the sewer pipes, and promotes considerable water saving, qualifying for a more optimized system. Despite of having , detailed the invention, it is important to understand that its application is not limited to the details and stages described herein. This invention is capable of other modalities and can be practiced or executed in a variety of other forms. It shall be understood that the terminology employed herein is for merely description, not limitation.
