Description

Device for closing drains.

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a device for the closure of drains applicable to such a sanitary element such as bidets, sinks, bathtubs, among others, so that the device will be set in correspondence with the mouth of the drain of the sanitary element by means of the fixing screw also the bowl-shaped piece constituting the aforementioned mouthpiece of the sanitary element proper.

The device can take a position closed where a rubber gasket contacts the side of the  cup-shaped piece and an open position in which the rubber gasket is placed above the bowl-shaped piece to allow water to escape.

Starting from this premise the essentiality of the invention is that the device has an anchoring means in the closed position that ensures said closure.

Background of the invention

Currently they exist in the state of the art different drainage devices with very different embodiments ranging from an all or nothing blockage produced by a system of ratchet between two pieces of plastic coaxially placed to other foreign documents such as invention patents US4447918 and US4420844, both currently expired.

Description of the invention

The device for closing drains that constitutes the object of the invention is installed in correspondence with the mouth of the drain of a sanitary element, where there is a cup-shaped piece with holes in its bottom that allows the passage of water for its drainage, at the same time that it is fixed by means of a central screw, which also fixes the assembly of the device of the invention to the terminal structure of the drain with respect to the body of the apparatus
sanitary.

The device is determined from a circular domed piece provided with a centered thread on its bottom face where an upper widening of an inner tubular piece that supports a rubber gasket that in the closed position the edge of said rubber will contact the side wall of the bowl-shaped piece to secure the tight closure of the drain. This meeting is retained between the tubular piece and the domed piece.

The inner tubular piece fits in addition to another outer tubular part that has two longitudinal grooves where two nerves of the piece are guided inside, also having a stop that is guided in another groove of the outer piece. This also includes in its edge bottom some highlights that are introduced in the holes in the bottom of the bowl-shaped piece to ensure its blockage during the assembly of the structure assembly by means of the screw axial fixing center.

The inner tubular part also has a narrow side wall portion limited between two cuts, to the Once that narrow portion has a tab. located in correspondence with a through slot of the piece Exterior.

In correspondence with a longitudinal edge of the through slot there is an arched and divergent track towards below on which the outgoing tab contacts, interrupting said track through a small recess where you enter and anchor the tab in the closed position of the device that ensures a anchoring of said position.

The whole device is fixed to the drainage structure of the sanitary apparatus through the head of the central axial fixing screw whose head is housed in a recessed from the bottom of the outer tubular part.

Around the outer tubular part is coupled a protective cap to prevent dirt, such as debris from soap or hair, which could interfere with the mechanism of device drive.

With this arrangement described, the device can adopt a superior open position where the set of The bulging piece, inner piece and rubber gasket meet located in a superior position in which said joint is not in contact with the side wall of the bowl-shaped piece, maintaining said position with the help of a spring that stops against the domed piece and outer tubular piece.

Instead, to reach the closed position you Scroll down that bulging piece set, inner piece and rubber gasket until the tab fits by elastic jump at the entrance of the arched track of the outer piece position is in which the board contacts its perimeter edge against the side wall of the bowl-shaped piece.

To get the open position of the device starting from the closed position it will be necessary to press back down on the domed piece, whereby the tab will be disengaged from the entrant away from the vertical of said entree thanks to the elasticity of the narrow portion elastic that includes the tab and thanks to the trajectory of the track, which before it recovers its initial position the tab and narrow portion, the bulging piece set, piece inner and rubber gasket will be placed superiorly in position open thanks to the upward force exerted by the spring.

Next to facilitate a better understanding of this descriptive report and being an integral part of the same accompany some figures in which with character illustrative and not limiting the object of the invention.

Description of the preferred embodiment

Considering the numbering adopted in the figures, the device for closing drains is applicable to sanitary appliances, which have a terminal structure 1 of drain that includes at least one outer support 2 and a body inside in the shape of bowl 3 with holes in its bottom and that join by means of a central screw 4 of axial fixation.

Starting from this premise, the device of the invention is determined from a domed piece so circular 5 whose bottom face starts a short threaded neck 6 where a widening 7 of an inner tubular part 8 is coupled which is inserted and guided axially within a second piece outer tubular 9 that has a bottom with a centered recess where the head of the central screw 4 is located to fix the assembly from the device to the terminal structure 1 of the device sanitary.

There is also a spring 10 that helps position the device in the open position, while it is located coaxially with the cited parts. One end of the spring 10 butts against the bulged piece 5 while the end opposite butt against the bottom of the outer tubular part 9.

The novelty of the invention focuses essentially on the two tubular pieces cited 8 and 9 and on all in the relationship and relationship between them to ensure the opening position where the drain of the water and the closed position where a rubber gasket 11 contacts with the side wall of the bowl-shaped body 3.

Said rubber gasket 11 engages in the broadening 7 of the inner tubular part 8, while its axial retention is secured by an annular shoulder 23 of the widening 7 and the bulging piece itself 5.

The inner piece 8 has two nerves longitudinal 12 that are guided and fit into individual grooves 13 of the outer part 9, this further including a through slot 14 where a solidary bumper 15 of a narrow portion is guided elastic 16 that is part of the side wall of the piece interior 8. Said pin 15 limits the travel stroke of the set of moving parts in solidarity with each other formed by the piece domed 5, rubber gasket 11 and inner part 8.

The inner tubular part 8 incorporates another narrow elastic portion 17 of sidewall with a flange terminal 18 embedded in another main through slot 19 located in the side wall of the outer part 9.

On a longitudinal edge of that through slot main 19 defines an arched track 20 divergent down over which the terminal tab 18 contacts, interrupting said track 20 by an intermediate entrant 21 which results in a hook 22 of the tab 18 when it is inserted into said inlet 21 which will correspond to the closed position of the device, thus ensuring said closed position.

This closed position is reached by pressing down on the bulged piece 5 until tab 18 is fits said recess 21. In this position the rubber seal 11 contact on the side wall of the bowl-shaped body 3 producing a tight seal.

The outer tubular part 9 incorporates in its lower edge some protrusions 24 that are inserted in the holes the bottom of the bowl-shaped piece 3 to ensure its lock during assembly and disassembly of the assembly structure by means of the central axial fixing screw 4, thus avoiding undue rotation of said structure.

Starting from this closed position, to to reach the open position it will be necessary to press again towards below on the bent piece 5 whereby the tab 18 is will disengage from incoming 21 moving away from the vertical of said incoming 21 thanks to the elasticity of the narrow portion elastic 17 which includes the tab 18 and thanks to the trajectory of track 20, which before it regains its initial position upper flange 18 and narrow portion 17, the piece assembly domed 5, inner piece 8 and rubber gasket 11 will be placed in the open position thanks to the upward force exerted by the spring 10.

Around the outer part 9 a coupling is coupled 25 bushing as a protective element to prevent dirtiness as traces of soap and hair for example, interfere in the device drive mechanism.
