It has in principle an angular structure consisting of a vertical branch 38 and a double horizontal bent branch 39 which is in contact with a ring seat 40 of the overflow pipe 8.
- a terminal lug 29' articulates where the free end of the wire 13 is connected, so that when actuating the pushbutton 1, the wire 13 pulls the bottom tilting trigger 36 making it tilt against the resistance of a recovery spring 41 that is part of such trigger 36, therefore the double horizontal bent branch 39 pushes the overflow pipe 8 upwards to proceed with the flushing of the tank.
- the first mechanism 15 and the second mechanism 16 return to their resting position thanks to the recovery spring 41 formed by a pair of elastic fins 41 that come into contact in the active position against the inner face of a part of the bell 7, position in which such elastic fins are stressed and tend to position the bottom tilting trigger 36 towards its resting position.
- This bottom tilting trigger 36 that receives the traction of the wire 13 of the pushbutton 1 and recovery spring 12, have a one-part configuration, thereby avoiding the need to mount separate springs as it occurs in other conventional flush systems.

Description
- The present invention, as expressed in the statement of this specification, relates to a toilet comprising a device for flushing toilet tanks that is of the type allowing to select a partial flush or a full flush of the tank by pressing down on a double pushbutton with two buttons, so that pressure on one of the two buttons of the double pushbutton is transmitted to the flush system through a wire made of steel, similar to that employed in bicycle brakes.
- On this premise, the invention improvements focus on characteristic linking means between the bell of the flush system and an outlet fixed at the bottom of the tank.
- Other features of the invention are focused on a first upper mechanism associated with the button and a second lower mechanism associated with the overflow, so that both cited mechanisms are connected by the wire, so that by pressing on one of the two buttons of the pushbutton, the overflow rises up releasing the outlet of water from the tank through the outlet and transmitting the movement through both cited mechanisms and the wire that connects them. When actuation on the pushbutton is ceased, the outflow of water from the tank is obturated.
- The benefits are initially the enormous versatility afforded by the new mounting design to the outlet of the tank.
- Currently, there are plenty of devices for flushing toilet tanks generally comprising a pushbutton, a flush system and an outlet fixed at the bottom of the tank, such that when actuating the pushbutton, the overflow pipe of the flush system is raised up releasing the outlet of water from the tank and when ceasing to exert pressure on such pushbutton, the initial position is recovered thus obturating again the outlet of the tank by means of an obturating rubber fixed to the overflow pipe that seals the outlet located within the outlet.
- For example, patent of invention number
ES2136547 - These devices for flushing toilet tanks are excessively complex in its operation, some of them being imprecise and expensive.

EP 0 796 954 discloses a device for operating discharge valves for water storage cisterns of sanitary installations comprising an element movable axially inside guide means under the thrusting action of a bellows attached to said guide means and made to expand by a predetermined quantity of compressed air introduced therein via control means of the operating device, wherein said bellows comprises rigid means movable therewith and designed to cooperate with a first seat and a second seat of a lever rotating about a fixed fulcrum designed to cooperate with elements of said rod so as to cause respectively starting or controlled stoppage of discharging. - In order to achieve the objectives and to avoid the drawbacks referred to in the preceding paragraphs, the invention provides a toilet comprising a device for flushing toilet tanks according with
claim 1. In theclaims 2 to 12 there are disclosed several embodiments of the invention in accordance with theindependent claim 1. - In an embodiment, the intermediate coupling base comprises a separate body that connects at its bottom part with the outlet of the tank.
- In a second embodiment, the intermediate coupling base and corresponding outlet comprise a single one-piece element.
- The first mechanism associated with the pushbutton is characterized in that it comprises a top tilting trigger with angular structure, one of whose branches articulates at its free end on an anterior axis integral to a housing of the pushbutton assembly, while at the joining area of the two branches of the cited trigger, it connects articulately with a terminal lug integral to one end of the wire, the free end of the other matching branch of the top tilting trigger connecting to a vertical rod of the pushbutton, the downward movement of which makes the top tilting trigger rotate against the resistance of a recovery spring that is part of a second mechanism associated with the overflow pipe.
- The second mechanism associated with the overflow pipe of the flush system is characterized in that it comprises a bottom tilting trigger which articulates into an intermediate part attached to the top of the bell, such trigger having an angular structure consisting of a vertical branch that incorporates the recovery spring and a double horizontal bent branch that is in contact with the underside of a ring seat of the overflow pipe, a terminal lug integral to one end of the wire connecting at the free end of the vertical branch of the bottom tilting trigger.
- The connection articulated in the anterior axis of the top tilting trigger is characterized in that it comprises an open extension mountable and detachable by virtue of a movement perpendicular to the direction of the anterior axis.
- Another feature of the invention is that the bottom tilting trigger has lateral appendages as means of articulation of such bottom tilting trigger, such lateral appendages coupling to the intermediate part, while they are in the area of confluence of the two branches of the above-mentioned bottom tilting trigger.
- The recovery spring of the bottom tilting trigger is characterized in that it comprises at least one elastic fin, in the active position of which it comes into contact at its free end against an inner part of the bell, so that in this active position of the at least one elastic fin, it tends to position the assembly of the overflow pipe and both first and second mechanisms towards its initial resting position corresponding to the obturation of the outlet of water from the tank.
- The end sections of the flexible tube that protects the wire are anchored, in a split top extension fixed to the housing of the pushbutton and in a split bottom extension fixed to the intermediate part attached to the bell of the flush system. This split structure of such extensions facilitates mounting and positioning of the flexible tube.
- Another feature of the invention is that the end sections of the flexible tube where the wire is guided, incorporate some retaining protuberances that are embedded in slots established in such split extensions.
- Another feature of the invention is that the inside of the neck of the fixed housing of the pushbutton comprises a first pair of opposing grooves that go through the entire length of said neck and a second pair of opposing grooves that only affect a lower section of said neck, some end protrusions integral to the vertical rod in the mounted position of the assembly of the pushbutton being fit in the second pair of opposing grooves, while, during its assembly, the end protrusions of the vertical rod go through the first couple of opposing grooves, the latter substantially facilitating assembly and disassembly of the vertical rod associated with the two buttons of the pushbutton without having to assemble and disassemble other elements.
- In another embodiment of the present invention, at least one of the battlemented protuberances of the lower part of the bell comprises at least one hole in the bottom of the same for the draining of water from the inside of the device. Thus, these holes prevent the effect of 'inverted glass' generated inside the bell since when said bell is raised for the draining of water by the outlet, the water inside the bell would be retained in the interior of the same by the above-mentioned effect which would hinder the descent of the device. Air enters inside the bell through the above-mentioned holes which ensures water outflow and ensures at the same time the correct descent of the bell and therefore a correct closure of the device.
- Next, in order to facilitate a better understanding of this specification and being an integral part of the same, the figures attached represent the object of the invention with an illustrative and not limiting character.

In this way thebottom part 7" of thebell 7 is retained by the interaction of the top part 7' and the coupling base 43-43'. - Above and in proximity to the
anchoring extensions 21, thebell 7 comprises inverted "U"-shaped cuts 44 that delimit actuatingportions 45 to tilt the citedanchoring extensions 21, in such a way that pressing onsuch actuation portions 45 manages to disengage theflush system assembly 4 with respect to the intermediate coupling base 43-43' thus achieving only axial disconnection. - The
first mechanism 15 associated with thepushbutton 1, comprises atop tilting trigger 26 with angular structure, one branch of which articulates at its free end on ananterior axis 27 integral to asupport 28 of thepushbutton assembly 1, while at the joining area of both branches of such top tilting trigger 26 it articulately connects with aterminal lug 29 integral to one end of thewire 13. The connection articulated in theanterior axis 27 comprises anopen extension 42 to facilitate its extraction perpendicular to the direction of suchanterior axis 27, also allowing a good lever arm without affecting the anchorage of thewire 13. - On the other hand, the free end of the other matching branch of the
top tilting trigger 26 is in contact with avertical rod 34 of thepushbutton 1, so that when actuating on the same, thevertical rod 34 descends against the resistance of aspring 35, suchvertical rod 34 pushing by its bottom end to the above-mentionedtop tilting trigger 26 by pulling thewire 13 and actuating thesecond mechanism 16 associated with theoverflow pipe 8 thus raising it upwards to cause the emptying of the tank. - The
pushbutton 1 comprises afixed housing 47 provided with aneck 48, saidneck 48 inwardly incorporating a first pair ofopposing grooves 49 going throughout the length of saidneck 48 and a second pair of opposinggrooves 50 only affecting a lower section ofsaid neck 48;end protrusions 51 integral to thevertical rod 34 in the mounted position of thepushbutton assembly 1 fitting in the second pair ofopposing grooves 50, while during its assembly theend protrusions 51 go through the first pair ofopposing grooves 49. - Therefore, the first pair of
opposing grooves 49 go through the interior of theneck 48 in its entirety, such that facing on them theend protrusions 51 of thevertical rod 34, saidvertical rod 34 is introduced, by the top, during its assembly, until it emerges by the lower end of theneck 48, overcoming the resistance of thespring 35, thereby achieving that the citedend protrusions 51 of thevertical rod 34 exceed said lower end of theneck 48, in order to then rotate 90° saidvertical rod 34 and thus be able to introducesuch end protrusions 51 in the second pair of smallerlength opposing grooves 50, that go internally only through a small portion of theneck 48, such as described above. - The action of the
spring 35 of the pushbutton moves back thevertical rod 34 to its working position, this time guided in the second pair of smallerlength opposing grooves 50, hiding theend protrusions 51 and leaving the pushbutton mounted without any possibility of disconnection between its different moving parts, such that in this way the assembly functions of the mechanism are simplified, by providing the user with the assembly fully prepared for its connection to the wire system. - In turn, on the
support 28 of the pushbutton 1 asplit top extension 30 is connected, wherein an end section of theflexible tube 14 is fixed provided withretaining protuberances 31 that are embedded insmall slots 32 ofsuch split extension 30, thus facilitating the attachment and assembly of theflexible tube 14. - The opposing end section of the
flexible tube 14 has other retaining protuberances 31' that are embedded in other slots 32' located in another split bottom extension 30' connected to the top of thebell 7 of theflush system 4. - On the other hand, the
second mechanism 16 associated with theoverflow pipe 8 includes abottom tilting trigger 36 that articulates at the top of thebell 7 throughlateral appendages 37 that are part of suchbottom tilting trigger 36. It has in principle an angular structure consisting of avertical branch 38 and a double horizontalbent branch 39 which is in contact with aring seat 40 of theoverflow pipe 8. - In the free end of the
vertical branch 38 of thebottom tilting trigger 36, a terminal lug 29' articulates where the free end of thewire 13 is connected, so that when actuating thepushbutton 1, thewire 13 pulls thebottom tilting trigger 36 making it tilt against the resistance of arecovery spring 41 that is part ofsuch trigger 36, therefore the double horizontalbent branch 39 pushes theoverflow pipe 8 upwards to proceed with the flushing of the tank. - When ceasing to press the
pushbutton 1, thefirst mechanism 15 and thesecond mechanism 16 return to their resting position thanks to therecovery spring 41 formed by a pair ofelastic fins 41 that come into contact in the active position against the inner face of a part of thebell 7, position in which such elastic fins are stressed and tend to position thebottom tilting trigger 36 towards its resting position. - This
bottom tilting trigger 36 that receives the traction of thewire 13 of thepushbutton 1 andrecovery spring 12, have a one-part configuration, thereby avoiding the need to mount separate springs as it occurs in other conventional flush systems.
