Description

HYDRAULIC DRIVING DEVICE FOR RAISING AND LOWERING THE COVERAGE AND SEAT COVER OF A RETRETE, AND

DRIVING METHOD

FIELD OF THE INVENTION

The present invention, in general, is related to the means and devices used in toilets or toilets; in particular, it refers to the means used to automatically raise and lower the cover of a toilet cover and more specifically it refers to a hydraulic actuation device for raising and lowering the cover and cover seat of the mouth of a toilet.

BACKGROUND OF THE INVENTION

As is known to all, the toilets of common use, are configured in such a way that structurally they comprise a cup consisting of a body with a central circular or oblong mouth, with an internal siphon that flows through a base that is fixed to the floor and where the exit of the siphon is connected to the sanitary drainage network; said cup comprises an upper tank where a volume of water is deposited, which is connected through a duct with said cup; wherein said pipelines comprise a float shut-off valve with actuating means for the discharge of water into the cup.

A water supply pipe from a water supply source of the domestic network or of the public network is connected directly in the upper water storage tank comprising a control passage valve; wherein said tank comprises valve means controlled by a float element for the control of the volume of water to be stored and discharged to the toilet, to dislodge urination and / or excrement. The mouth of the toilet bowl comprises holes in the rear part where fixing means of a folding lid and seat covering the mouth are inserted, which for reasons of hygiene are arranged on the mouth of the cup, preventing the user have direct contact with the surface of the toilet, in addition to providing greater comfort and comfort to the user.

The cover of the cup consists of a solid body similar to the mouth (circular or oblong) and the seat has an annular or elliptical shape that follows the contour of the mouth of the cup; Some seats are shaped like a horseshoe. Said seat is used so that people sit on it and avoid contact directly with the surface of the cup; in some cases the seat is cushioned for comfort; while the lid allows covering the mouth of the cup.

When a female person makes use of the toilet, she usually tends to lift the lid with her hands or with at least one hand, which implies contamination, lack of hygiene, etc.

As for a male person, the existing problem is well known, because when a man only pretends to urinate, usually if he has a good habit, he lifts both the lid and the seat with his hands to avoid splashing the seat with urine and keep the seat clean, with the sanitary implications already indicated by the direct contact of the hand with the cover and seat; but on many occasions the men, when the lid is covering the mouth of the cup, only lift the lid, or if the lid is raised they no longer lift the seat, which implies that when they urinate they splash and wet the seat with urine, causing disgust in other users of the toilet and causing contamination of the lid that could be a source of infection for the other users.

In the state of the art, several mechanical, hydraulic and pneumatic mechanisms and devices were found that allow lift the lid and / or the toilet seat, for example, the Mexican patent application PA / a / 2001/006808 by Jaime Barrios Gómez Garibay, dated July 2, 2001 was found, which seeks to protect a mechanism to lift the lid Excused indirectly and without the use of hands, characterized by being formed by a hydraulic system with two plastic valves, one of which is arranged on the floor and the other is arranged under the lower plastic ring-shaped lid or in the form of a horseshoe, which covers the upper surface of the rate of the toilet; both valves being interconnected through a high pressure hose; the valve being disposed on the floor of a circular bag shape with the upper surface bulged, which houses inside a certain amount of a liquid; while the valve that is disposed below the lower plastic cover in the form of a ring or in the shape of a horseshoe, is a cylinder with an inner piston or in the form of an accordion bellows.

The patent application GB 2376475 (A) of Moran Lynn and Murphy Darly of December 18, 2002 was found, which seeks to protect a mechanism to lift the seat 6 and the lid 7, designed to conform to standard toilets that is actuated to lift The cover and seat by pressing a pedal 4 operated by the foot that surrounds the lower part of the toilet bowl; a metal housing 3 housing the drive mechanism 5 to lift said cover 7 and seat 6, consisting of bars and levers.

Utility model PA / u / 2005/000273 was found with concession number MX1636 by David Herrera Gurrola, granted on December 18, 2006 that protects a device to raise and lower the seat of a toilet, the device generally includes a rotation axis placed below the toilet seat and that is attached or makes contact with it; a lever attached to the axis of rotation and which is moved by a user in order to transmit its movement towards the axis of rotation, which, being together with the feeling or making contact with it achieves the desired movement of ascent or descent of the seat; the axis of rotation that is housed in channels or ducts of the existing hinges formed by the lid, the seat and the toilet hinge brackets, or is housed along a housing provided in a support base that is fixed in the mounting holes that exist in the back of the toilet bowl.

The Mexican patent application document Pa / a / 2006/012503, by Mark Anthony Dercksen and Johannes Gideon Francois Johannes, was also found, which seeks the protection of a hydraulic foot-operated seat lift that can be easily installed in a excused; The universal bracket with a retained cylinder and a piston is mounted to the cup the toilet when using the existing toilet seat fasteners; The toilet seat lift is activated by applying foot pressure to the pedal, which in turn opens a valve to supply water pressure from the existing toilet water supply to the cylinder and piston.

It was also found the US patent 4,291,422 of John J. Shoemaker and Kenneth R. Stark, of September 29, 1981, which discloses a device for raising and lowering the members of the lid and the seat of a dressing table comprising a pair of independent hydraulic systems, operatively associated with one of the dressing table members (cover or seat). Each hydraulic system includes a manually operable control valve, a hydraulic cylinder that has a water inlet / connection port arranged at each of its distal ends and means that operatively connect the piston rod of the cylinder with the member (cover or seat) associated toilet. Any of the dressing table members (cover or seat) can be controlled with the hydraulic system associated with a control valve that directs the water to one of the cylinder ports, while the water from the extractor receives the other port that moves the Ia piston rod in a first direction, moving the dresser member (cover or seat) rotatably in one direction. In the operation, the toilet member lowers the control valve to reverse the ports of the cylinder they receive and that deplete the water that causes the piston rod to move in a second direction through which the rotating toilet member moves in The other address.

None of the documents located protects or discloses a hydraulic drive device to raise and lower the cover and seat cover of a toilet automatically and taking advantage of the same source of fluid used to fill the elevated tank and to dislodge the excreta towards the drain, where said device is of simple structure, of easy installation and of easy operation that can be operated by means of sensors or through manually operated buttons or with the feet.

This device is novel and represents inventive activity, since it has been designed and developed after multiple tests, developments, research, investment of financial resources, personnel and supplies, which has allowed the obtaining of the device which we believe meets novelty since no document is found that discloses its existence and that it cannot be deduced from the combination of information from the documents located, so that it complies with inventive activity.

BRIEF DESCRIPTION OF THE INVENTION

In general, the hydraulic actuation device for raising and lowering the cover lid and the seat of a toilet in accordance with the present invention, consists of a housing comprising two hollow chambers attached one left and one right, the chambers housing an axis left swivel and a right swivel shaft, respectively; both axes fixedly comprise a counterweight that can rotate together with the axis inside the chambers; said axes are fixed inside the housing with rotational movement capacity; each chamber also houses a left and right elastic diaphragm, attached and interacting with the counterweights, said diaphragms comprise at least one connection pivot where a supply and / or output fluid duct is connected to actuate-push the weights when they inflate with fluid and cause the rotation of said axes; a lid of the mouth of the toilet and a seat disposed below the lid and on the periphery of the mouth of the toilet bowl, comprise in the rear two left and right eyebrows connecting with a hole through which it is inserted a fixing bolt that is fixed at the ends of the rotating axes with the counterweights, anchoring the cover to the left axis and the seat to the right axis; so that the left rotating shaft is firmly fixed to the left connecting eyebrow of the cover, the shaft passes through the hole of the left eyebrow of the seat without locking the seat and the right rotating shaft is firmly fixed in the right eyebrow of the seat, the shaft passes through the hole of the eyebrow of the lid without locking the lid.

When the pressurized fluid is introduced through the pivots, the diaphragms are filled with fluid, pushing the counterweights attached to the left and right rotating axes, rotating them, and when the left and right axes are attached to the cover and seat, respectively, they allow them to rise; when the fluid is expelled from the diaphragms, the counterweight helps the gentle fall due to gravity of the cover and seat.

The device can operate in different ways in different scenarios, for example, it allows lifting the lid only, when the lid and the seat are folded down, this when it is going to be used to defecate by men and women; lift the lid and the seat simultaneously when they are down, this when it will be used for a man to urinate; lower the seat when the lid and the seat are raised, this when it will be used to defecate by men and women; lift the seat when the lid is raised and the seat folded down, this when it will be used to Let a man urinate.

Said device housing in its preferred mode consists of two modules, a left module and a right module, both modules are adapted to engage each other. Said housing comprises on its lower face a pair of hollow fixing tubes with spaced outer rope, projected inferiorly and coinciding with the holes of the toilet bowl by means of which it is fixed with nuts to said cup. Through said hollow tubes, the working fluid feed pipe is passed to said diaphragms.

In their preferred embodiment, the chambers are semicircular and the counterweights attached to the rotating shafts are substantially of a triangular prism with a curved base, which are smaller than said chambers in order to be able to move rotatably within them and press the diaphragms.

There are two modes of the invention to pass the working fluid to the diaphragms inside the chambers of the device housing and allow the seat and the toilet lid to rise and fall, where the working fluid used is water from the intake Main feed to the toilet tank.

In one of the modes of the invention, the device is automatically activated ("Premium" version) and in another of the modes the device is operated with contact actuating elements ("Standard" version).

In the automatic actuation mode ("Premium" version), the device is powered by a network of water supply pipes whose power is regulated by three-way solenoid valves, two left and right motion sensors and a central presence sensor in communication with an electronic card that processes the signals of the sensors to operate said solenoid valves. Said modality then consists of two supply ducts connected to a duct of the main power supply duct to the toilet water tank and to a path of the two three-way solenoid valves arranged on the sides of the back of the cup; in the second path of the solenoids, the feeder duct connected to the pivot of the left and right diaphragms is connected, and in the third path of the solenoids, the water discharge ducts of the diaphragms are connected, connected from the solenoids to a main discharge duct that flows into the toilet water tank.

In this mode, the diaphragms have only one pivot through which the working fluid enters and leaves.

The left and right motion sensors, the central presence sensor and the electronic card, are housed within the housing of the drive device, the sensors being exposed in the upper front part of the device housing; said electronic card is connected to the solenoid valves to activate them according to the need of the hydraulic system.

In operation, in the different work scenarios, already indicated above, the device operates as follows:

The premium version device can lift the lid or seat and _what the lid at the same time by means of water pressure. To lift only the cover, it is necessary to pass the hand or foot through the left motion sensor, when said sensor is activated, the signal travels to the electronic board and in turn sends a signal to the left solenoid valve to be activated, allowing the flow of water through the left feeder pipe to the left diaphragm; by means of the water pressure said left diaphragm is inflated by pressing the left counterweight fixed to the left rotating axis to move inside the left chamber and turning the cover which is connected by means of a bolt to said left rotating shaft to the open position.

To lift the cover and the seat at the same time, it is necessary to pass the hand or foot through the right motion sensor, when said sensor activates the signal travels to the electronic card and that in turn sends a signal to the solenoid valves left and right, these are activated allowing the flow of water through the left and right ducts to the two diaphragms; by means of the water pressure said diaphragms are inflated, forcing each diaphragm to press the corresponding counterweights, to move inside the chambers of the device and rotating the cover and the seat simultaneously, until the open position.

In both situations while the person is close to the device, the central presence sensor sends a signal to the electronic card to keep both solenoid valves open forcing the cover and seat to remain in the open position. Once the person is removed from the place, the central presence sensor sends a signal to the electronic card so that it in turn sends the signal to both solenoid valves, closing the water supply and opening the path where the pipelines are connected of discharge of water for the drain that goes to the toilet tank or to the same toilet through the main discharge duct. With this action the pressure of the diaphragms is released and by gravity the lid or the lid and the seat are closed, as the case may be.

This closing action also happens if both the lid and the seat are in the open position and the person passes his hand or foot through the left sensor and said sensor sends a signal to the electronic card where it is in turn active The left solenoid valve so that the pressure of the left diaphragm is released and the water is released in the toilet tank or in the same toilet so that the seat is lowered by gravity without lowering the lid.

In the same way, if the cover is in the open position, the user can pass the hand or foot through the right motion sensor, when said sensor is activated, the signal travels to the electronic card and in turn sends a signal to the right solenoid valve, this is actuated and allows the flow of water through the right duct to the right diaphragms. By means of the water pressure, said diaphragm is inflated, forcing the right counterweight to move inside the right chamber of the device and rotating the seat up to the open position.

In the Standard mode where the device is operated with contact elements; The device is fed by a network of pipes from a distributor element, said distributed elements are arranged in the rear part of the cup and connected directly to the main water supply duct to the toilet tank.

In the case of the left diaphragm of the device, there is a first left supply line connected to the distributor element and a left button or actuating valve with the foot or hand disposed on the floor next to the toilet, which takes the water from the main water supply pipeline; a second left distribution duct connected from the left actuation button to the distributor element in communication with a third left supply duct leaving said distributor element and connected to a first upper pivot of the left diaphragm of the device, a fourth duct of discharge connected to a second pivot of the left diaphragm and to the distributor element and which discharges water from said diaphragm and a main discharge pipe connected from the distributor element to the toilet water tank comprising at its end a valve with a pressure device that opens when the tank is discharged before the pressure differential, allowing the discharge of water from the system.

The same configuration of pipe connections and a right button or actuator valve with the foot or hand, is understood for the right diaphragm.

In the operation of the device of the standard version, the cover or the seat and the cover can be lifted at the same time, by means of the water pressure. To lift only the lid, it is necessary to press the left operating button or valve with the foot or the hand; this allows the flow of water from the main feed pipeline through the first left feed pipeline and continuing through the second left distribution pipeline to the distributor elements, to pass through the third left feed pipeline to the left diaphragm. By means of the water pressure, said left diaphragm is inflated by pressing the left counterweight by moving it into the left chamber of the device and rotating the lid to the open position.

To lift the cover and the seat at the same time, it is necessary to press the right button or actuator valve with the foot, which allows the flow of water from the main supply line through the first supply line right and continues through the second right distribution duct to the distributor element, to pass through the third left duct and also through the third right feed duct to the left and right diaphragms to press the weights and rotate the left and right axes to lift the cover and the seat to the open position. To close the lid and the seat, it is necessary to discharge the water from the toilet tank and once the valve sensitive to the pressure of the water disposed at the end of the main discharge duct is lowered, allowing the diaphragms left and right, discharge the water inside the tank, from the toilet by and allowing gravity and the weights of the counterweights, the lid and the seat to go down to the closed position.

The cover and back cover, in any of the modalities, are raised at an approximate angle of 85 ° I which allows them to have a certain inclination, which favors the gradual lowering of the cover and seat, assisted by the counterweights.

The device as described further allows a user to lift the cover and seat- by hand if he does not wish to operate the device with the automatic actuation system or with the contact element actuation system, deactivating it.

In another of the modalities, where the toilet is exclusively for a male person, the system allows to deactivate the left valve and sensor so that only the right valve and sensor can be activated, which allows the system to be raised and lowered. the seat exclusively, keeping the lid permanently raised.

In order to better understand the characteristics of the invention, the present description is attached, as an integral part thereof, to the drawings with illustrative but not limitative character, which are described below.

The characteristic details of the hydraulic drive device for raising and lowering the cover and seat cover of a toilet, is clearly shown in the following description and in the accompanying illustrative drawings, serving the same reference signs to indicate the same parts.

Referring to Figure 1 which shows an explosive of the hydraulic drive device for raising and lowering the cover and seat cover of a toilet, in accordance with the present invention. In said figure the device consists of a housing 1 formed by two modules 1a and 1b, a left module 1a and a right module 1b, both modules are adapted to engage each other; The already assembled housing defines a left hollow chamber 2 and a right hollow chamber 3 (not shown) in a semicircular manner, adapted to receive a left rotating shaft 4 and a right rotating shaft 5, and to accommodate a left counterweight 6 and a right counterweight 7, respectively. These axes are fixed inside the chambers with rotational movement capability; each of the chambers 2 and 3 also houses a left elastic diaphragm 8 and a right one 9, attached and interacting with the weights 6 and 7; said diaphragms 8 and 9 comprise at least one connection pivot 10 where a working fluid supply and / or discharge duct (not shown) is connected which cause said diaphragms to increase in volume to drive-push the weights 6, 7 and cause the rotation of said left 4 and right 5 axes.

With reference to Figures 1 and 2, a lid 11 of the mouth of the toilet and a seat 12 disposed below the lid 1 and on the periphery of the mouth of the toilet bowl (not shown), the lid and the seat they comprise in the rear part two connecting eyebrows left 13a, 13b and right 14a, 14b with hole through which a left fixing bolt 15 and right 16 is inserted which is fixed at the ends of the respective axes rotating left 4 and right 5. The left bolt 15 fixes and anchoring the cover 11 to the left axis 4 with the left connecting eyebrow 13a passing without being fixed through the hole of the left connecting eyebrow 13b of the seat 12, allowing its rotation; while the right bolt 16 fixes and anchors the seat 12 to the right axis 5 through the right connecting eyebrow 14b passing without being fixed through the hole of the right connecting eyebrow 14a of the cover 11 allowing its rotation.

When the pressurized fluid is introduced through the pivots 10, the diaphragms 8 and 9 are filled with water, pushing the weights 6 and 7 attached to the left 4 and right 5 rotating shafts, rotating them, and the axes being joined Left 4 and right 5 to cover 11 and seat 12, respectively, allow them to rise. When the water is expelled from the diaphragms 8 and 9, the counterweights 6 and 7 help the gentle fall by gravity of the lid 11 and seat 12.

With reference to Figure 1, said housing 1 comprises on its lower face a pair of hollow fixing tubes 17 with outer rope spaced, projected inferiorly and coinciding with the holes of the toilet bowl (not shown) by means of which fixed with nuts (not shown) to said cup. Through said hollow tubes 17, the working fluid feed pipe is passed to said diaphragms 8 and 9.

Referring to Figure 3 which illustrates a side view of a conventional toilet with the hydraulic actuator for raising and lowering the cover and seat cover of a toilet. In said figure, the device is fixed in the cup 18 of a toilet 19 by means of the hollow tubes 17 of the housing 1 with nuts 20, so that the lid 11 and the seat 12 are arranged on the cup 18.

Referring to Figure 4 showing an explosive of the hydraulic drive device to raise and lower the lid of cover and seat of a toilet, in the automatic actuation mode (Premium version). In said figure, the same numerical references described in the figures are used

1 to 3 for the case of the device; In this mode, the device is powered by a network of water supply pipes whose power is regulated by two three-way solenoid valves 21 and 22, two left-hand motion sensors 23 and

^ right 24 and a central presence sensor 25 in communication with an electronic card 26 that processes the signals from the sensors to actuate said solenoid valves 21 and 22.

With reference to Figures 4 to 7, two left 27 and right 28 supply ducts connected to a branch 29 of the main power supply duct 30 that feeds water to the water tank 31 of the toilet and to a path of the corresponding valves three-way solenoids 21 and 22 arranged on the sides of the back of the cup 18; In the second path of the solenoid valves, the left 32 and right feed lines 33 are connected, which is connected to the pivot 10 of the left and right diaphragms 8, and in the third path of the solenoids, the water discharge ducts 34 are connected. and 35 of the diaphragms, connected from solenoids 21 and 22 to a main discharge duct 36 which flows into the water tank 31 of the toilet.

Figure 4 also shows the cover caps left 37 and right 38 of the housing 1 of the device.

The same reference numbers are used in Figures 5 to 7 to indicate the elements described in Figure 4.

Figure 5 shows the lid 11 and the seat 12 folded over the mouth of the cup 18 of the toilet 19. Figure 6 shows the lid 11 raised and in the seat 12 folded down. Figure 7 shows the cover 11 and the seat 12 raised.

In Figures 8a to 8e illustrating cross sections of the device in the automatic actuation mode (Premium version), illustrating the evolution of a diaphragm during its filling with working fluid to drive the counterweight and rotate it together with the rotating shaft to lift the cover and / or the seat. In said figures, the three-way solenoid valve 21 can be seen, the lower track 39 being the one in which the left power supply line 27 (not shown) is connected connected to the branch 29 of the main power supply line 30 (not shown) ); in the second track 40 the left feeder duct 32 is connected which is connected to the pivot 10 of the left diaphragm 8 disposed within the left chamber 2 of the device housing 1, attached to the counterweight 6, and passing through the interior of the hollow tube 17 threaded with which the nut 20 is fixed to the cup and in the third track 41 the water discharge duct 34 (not shown) is connected through which the water leaving the left diaphragm 8 is discharged.

Figures 8a to 8e illustrate the gradual filling sequence of working fluid of the left diaphragm 8, which allows the left diaphragm 8 to push the counterweight 6 fixed to the left rotating axis 4 into the chamber 2, so that when inflate with water, causes the rotation of the left axis 4 that is fixed to the cover 11 (not shown) by lifting it.

In figures 9a to 9e, an inverse sequence can be seen, illustrating the evolution of a left diaphragm 8 that reduces its volume during its emptying, returning the counterweight 6 and rotating axis 4 to a resting position that leads the lid to Ia lying position

In these figures it can be seen how the solenoid valve 21 is actuated by activating the piston 42 that clears the third track 41 where the discharge duct 34 (not shown) is connected, leaving the water from the diaphragm 8.

This operation is the same with the right elements of the device in which the right axle is fixed to the seat to raise or lower it.

Figure 10 shows the two left and right movement sensors 23 and the central presence sensor 25 in communication with an electronic card 26 that processes the signals from the sensors to actuate said solenoid valves 21 and 22 with which it is in communication.

Figure 10 shows the sensitivity adjustment means 43 of the sensors 23, 24, 25.

With reference to figures 4 to 10, in operation, the following events occur:

The Premium version device allows to lift the lid 11 or the seat 12 and the lid 11 at the same time by means of the water pressure. To lift only the cover 11 it is necessary to pass the hand or foot through the left motion sensor 23, when said sensor activates the signal travels to the electronic card 26 and this in turn sends a signal to the left solenoid valve 21 to that it is activated, allowing the flow of water through the left feeder pipe 32 towards the left diaphragm 8; by means of the water pressure said left diaphragm 8 is inflated by pressing the left counterweight 6 fixed to the left rotary axis 4 to move inside the left chamber 2 and turning the cover 11 that is connected by means of the bolt 15 to said rotating axis left 4 to the open position.

To lift the cover 11 and the seat 12 at the same time, it is necessary to pass the hand or foot through the right motion sensor 24, when said sensor is activated the signal travels to the electronic card 26 and that in turn sends a signal to the left 21 and right 22 solenoid valves, these are actuated and allowing the flow of water through the left 32 and right 33 ducts to the two diaphragms 8 and 9; by means of pressure of the water said diaphragms are inflated, pressing each diaphragm to the corresponding counterweights left 6 and right 7, to move inside the chambers 2 and 3 of the device and rotating the lid 11 and the seat 12 simultaneously, until the open position .

In both situations while the person is near the device, the central presence sensor 25 sends a signal to the electronic card 26 to keep both solenoid valves 21 and 22 open, forcing the cover 11 and seat 12 to remain in the position of open. Once the person is removed from the place, the central presence sensor 25 sends a signal to the electronic card 26 so that it in turn sends the signal to both solenoid valves 21, 22, closing the water supply and opening the path where the water discharge ducts 34, 35 are connected to the drain that goes through the main discharge duct 36 to the tank 31 of the toilet or to the toilet itself. With this action the pressure of the diaphragms 8 and 9 is released, and by gravity the lid 11 or the lid 11 and the seat 12 are closed, as the case may be.

This closing action also occurs if both the cover 11 and the seat 12 are in the open position and the person passes his hand or his foot through the left sensor 23 and said sensor sends a signal to the electronic card 26 where it is in turn, the left solenoid valve 21 is activated so that the pressure of the left diaphragm 8 is released and the water is released in the tank 31 of the toilet or in the same toilet so that the seat 12 is lowered by gravity without the need to lower the lid. In the same way if the cover 11 is in the open position, the user can pass the hand or foot through the right motion sensor 24, when said sensor activates the signal travels to the electronic card 26 and is in turn Ie sends a signal to the right solenoid valve 22, this is actuated and allows the flow of water through the right duct 33 towards the right diaphragms 9. By means of the water pressure said diaphragm 9 is inflated forcing the right counterweight to move inside the right chamber 3 of the device and rotating-raising the seat 12 to the open position.

With reference to Figures 11 to 14, which show the hydraulic drive device for raising and lowering the cover and seat cover of a toilet, in the drive mode with contact elements (Standard version). In these figures the same numerical references described in Figures 1 to 3 are used for the case of the device; In this embodiment, the device is fed by a network of pipes from a distributor element 44, said distributor element is arranged in the rear part of the cup 18 and connected directly to the main water supply duct 30 to the tank 31 of the toilet 19.

The left diaphragm 8 and the right 9, comprise a first left and right feed duct 45 respectively, connected to the distributor element 44 and a left or right actuator button or valve 48, respectively, arranged on the floor next to the toilet, which drink water from the main water supply pipeline 30; a second distribution line left 49 and right 50 connected from the corresponding actuating valves with the hand or foot, left 47 and right 48, to the distributor element 44 in communication with a third left supply pipe 51 and right 52 leaving of said distributor element 44 and is connected to a first upper pivot 10 of the corresponding left and right diaphragms 8 of the device; a fourth left discharge duct 53 and right 54 connected to a second pivot (not shown) of the left diaphragm 8 and right 9 and to the distributor element 44 and which discharges water from said diaphragms, and a main discharge duct 55 connected from the distributor element 44 towards the water tank 31 of the toilet 19 comprising at its end a valve with pressure device 56 that opens when the tank 31 is discharged to the pressure differential, allowing the discharge of water from the system.

The same reference numbers are used in figures 12 to 14 to indicate the elements described in figure 11.

Figure 12 shows the lid 11 and the seat 12 folded over the mouth of the cup 18 of the toilet 19. Figure 13 shows the lid 11 raised and in the seat 12 folded down. Figure 14 shows the cover 11 and the seat 12 raised.

With reference to Figures 15a to 15e, which illustrate cross-sections of the device in the drive mode with contact elements (Standard version), illustrating the evolution of a diaphragm during filling with working fluid to boost the counterweight and rotate it together with the rotating shaft to lift the lid and / or the seat. In said figures, the threaded hollow tube 17 is shown with which the device is fixed in the holes of the toilet bowl by means of the nuts 20, through said hollow tube 17 the third left feed duct 51 is passed where the water is dosed from the distributor element 44 (not shown) and which is connected to the first upper pivot 10 of the left diaphragm 8 disposed within the left chamber 2 of the housing 1 of the device, attached to the counterweight 6. In said Figures show the sequence of gradual filling of working fluid of the left diaphragm 8, which allows the left diaphragm 8 to push the counterweight 6 fixed to the left rotating axis 4 inside the chamber 2, so that when inflated with water, causes the rotation of the left axis 4 that is fixed to the cover 11 (not shown) by lifting it.

In figures 16a to 16e, an inverse sequence can be seen, illustrating the evolution of the left diaphragm 8 that reduces its volume during its emptying, returning the counterweight 6 and rotating axis 4 to a resting position that leads to The lid to the lying position, when the water comes out through the fourth left discharge duct 53 connected in a second pivot 57 of the diaphragm 8 that vents the water to the distributor element 44 and this discharges it through the main discharge duct 55 ( not shown) towards the water tank 31 of the toilet 19 which comprises at its end a valve with pressure device 56 that opens when the tank 31 is discharged before the pressure differential, allowing the water discharge from the system (see figures 12 to 14).

This operation is the same with the right elements of the device in which the right axis is fixed to the seat to raise or lower it.

With reference to figures 11 to 14 and 15a-15e and 16a-16e, in operation of the device of the standard version, the cover 11 or the seat 12 and the cover 11 can be lifted at the same time, by means of the water pressure . To lift only the cover 11, it is necessary to press the left actuating button or valve by means of the foot or the hand 47; this allows the flow of water from the main feed duct 30 through the first left feed duct 45 connected to the distributor element 44 and continuing through the second left distribution duct 49 to the distributor elements 44, to pass through the third left duct of supply 51 towards the left diaphragm 8. By means of the water pressure said left diaphragm 8 is inflated by pressing the left counterweight 6 by moving it inside the left chamber 2 of the device and turning the cover 11 to the open position.

To lift the cover 11 and the seat 12 at the same time, it is necessary to press the right button or right actuator valve 48 by the hand or the hand, which allows the flow of water from the main supply pipe 30 through the first pipe power supply 46 connected to the element distributor 44 and continues through the second right distribution duct 50 towards the distributor element 44, to pass through the third left duct 51 and also through the third right supply duct 52 to the left 8 and right 9 diaphragms to press the weights 6 and 7 and rotate the left 4 and right 5 axes to lift the cover 11 and the seat 12 to the open position. To close the lid 11 and the seat 12, it is necessary to discharge the water from the tank 31 of the toilet and once its level drops, the pressure sensitive valve 56 of the water disposed at the end of the main discharge duct 55 opens, allowing the left 8 and right 9 diaphragms to discharge the water inside the toilet tank 31 by and allowing gravity and the weights of the weights 6 and 7, the cover 11 and the seat 12 to fall to the closed position.
