Description of preferred embodiments

As illustrated in Figure 1, the toilet device comprises at least one bezel 1, a first attachment system 2 of the bezel to the bowl 3 of the toilet and a first hinge 4 associating the bezel 1 to the first fastening system 2. L 'assembly bezel / first fastening system / hinge is monobloc, that is to say it consists of a single block without assembly of different elements, for example using screws, nuts and separate joints said single block. The different elements are not removable.

Such a device for toilets has hitherto irreconcilable characteristics since it is both monobloc and some of its elements such as the bezel 1 and the first fastening system 2 are movable relative to each other. Such conciliation is made possible by means of a first hinge 4 associating the bezel 1 to the first fastening system 2 made of a first polymeric material of hardness between 30 and 90 Shore A.

The first fastening system 2 comprises one or more elements resting on the tank and making the mechanical connection between the first hinge 4 and the tank 3 especially when the bezel 1 is in the raised position. The first fastening system 2 may comprise at least one hole through 17 allowing the passage of an outer securing element of the bezel to the tank, for example a fastening element such as a rod 16 fixed to the fastening system 2bis of the flap 5 or by any other known means of the skilled person. The first fastening system 2 may comprise the solidification element if the toilet device does not have a flap or if the flap 5 is secured to the tank 3 by means of the first fastening system 2.

According to a preferred embodiment, the first hinge 4 is formed in a first flexible polymer material, that is to say with a hardness of between 30 and 90 Shore A. According to a particularly preferred embodiment, the first hinge 4 has a thickness from 1 to 8 mm. Said first hinge 4 is smooth over its entire surface and integrated with the rest of the device. Preferably, said first hinge 4 extends over all or part of the face with which it is in contact with the bezel 1, said face being preferably the rear lateral face of the bezel. It therefore does not substantially allow liquids, dirt or microbes to pass into inaccessible areas or, for example, in the area between the fixing system 2 and the toilet water tank.

According to a particular embodiment, the first hinge 4 consists of a first polymeric material chosen from copolyamides (COPA), copylesters (COPE), polyurethane derivatives (TPU), styrenic derivatives (TPS) such as Styrene Block Polymers (SBC) such as Styrene Ethylene Butylene Styrene (SEBS), polyolefins and olefinic derivatives such as "polyolefin elastomers" (POE), "olefin block copolymers" (OBC), polypropylenes (PP) and their mixtures, vulcanized (TPV) or not (TPO).

The bezel 1 can be of any suitable form so as to best adapt to the upper face 19 of the tank 3 toilet. According to a mode of T / FR2013 / 000320

preferred embodiment, the bezel 1 is made of two elements 1a and 1ter (Figure 2) assembled together. The first element 1a has substantially a gutter shape so as to form the side and upper faces of the bezel 1 and give the bezel thickness 1. The second element 1ter is a planar element whose underside is substantially devoid of asperity or rib, said second element Iter forming the underside of the telescope 1. The two elements 1a and 1b may be assembled by any means known to those skilled in the art, in particular by welding, in order to obtain a hollow and light set. Such an embodiment makes it possible to obtain a telescope 1 that is comfortable, easily cleanable and whose economic cost remains low.

According to an advantageous embodiment, a first bead 8, preferably made of a polymer material having a hardness of between 30 and 90 Shore A, is placed on the outer periphery of the lower face of the bezel 1. Preferably, the first bead 8 covers one of the welds between the elements 1a and 1ter of the bezel 1. More preferably still, the first cord 8 replaces the welding operation and provides the connection between the elements 1a and 1ter. The first cord 8 is advantageously configured to ensure a good seal between the bezel 1 and the vessel 3. It advantageously forms a closed ring. Preferably, said first bead 8 also allows an adaptation of the bezel 1 to any type of tank 3 projecting from the underside of the bezel 1 in the direction of the face 19 of the vessel 3 in the low position.

According to an embodiment compatible with the preceding modes, a second bead 8bis, preferably made of a polymer material with a hardness between 30 and 90 Shore A, is placed on the inner periphery of the lower face of the bezel 1, possibly said second bead 8bis covers one of the welds between the elements 1a and 1b of the window 1. Preferably, the second cord 8ab replaces the welding operation and 00320

8

provides the connection between the elements 1a and 1b. The second cord 8bis is advantageously configured to guide the drops of liquid and allow them to flow and fall inside the tank 3 instead of streaming under the bezel 1. It advantageously forms a closed ring.

According to a preferred embodiment, a bead 8ter, preferably made of a polymer material with a hardness of between 30 and 90 Shore A, is also placed on the outer periphery of the lower face of the flap 5. The bead 8ter is advantageously configured to connect the upper face of the telescope 1 and the flap 5.

The polymer cord or cords, in particular cords 8 and 8ter, are advantageously configured to allow a silent operation of the toilet flush and / or non-diffusion of odors. They are preferably configured to participate also in the damping of the bezel 1 and / or the flap 5 during their folding. When the bezel 1 and the flap 5 are both folded down, the polymer cords preferentially airtight, contribute to a higher water pressure inside the tank 3 and a better evacuation.

FIGS. 3 and 4 respectively represent the upper and lower faces of one embodiment respectively of the flap 5 and the window 1. The lower face of the window 1, facing the upper face 19 of the tank 3, advantageously has at least one damping pad 7, preferably of ovoid shape, configured to prevent the sliding of the telescope 1 on the tank 3.

Preferably, the damping pad 7 is made of a polymer material having a hardness of between 30 and 90 Shore A and is advantageously configured to present a "stop stop" function between the bezel 1 and the tank 3 in the folded position. The flexibility of the polymer material allows a damping the bezel 1 in the folded position. The thickness of the damping buffer 7 may be calculated so as to participate in the damping at the end of the stroke during the descent of the telescope 1 on the tank 3.

According to a preferred embodiment, the toilet device also comprises a flap 5 and a second hinge 6 associating the flap 5 with a second fastening system 2a. The second fastening system 2bis allows or intervenes in fixing the flap 5 with the tank 3. The second fastening system 2a may comprise at least one through hole allowing the use of an external securing element. The second fastening system 2bis may comprise a fastening element to the tank 3 or a securing element to the first fastening system 2, for example a fastening element known to those skilled in the art such as a screw and a nut.

According to an advantageous embodiment, the second hinge 6 is made of a second polymeric material with a hardness of between 30 and 90 Shore A. The second polymer material of the second hinge 6 may be identical to or different from the first polymer material of the first hinge 4 .

According to a particular embodiment, the second hinge 6 is made of a polymeric material chosen from copolyamides (COPA), copylesters (COPE), polyurethane derivatives (TPU), styrenic derivatives (TPS) such as styrene Block Polymers (SBC) such as Styrene Ethylene Butylene Styrene (SEBS), polyolefins and olefinic derivatives such as "polyolefin elastomers" (POE), "olefin block copolymers" (OBC), polypropylenes (PP) and their mixtures, vulcanized (TPV) or not (TPO).

Preferably, said second hinge 6 extends over all or part of the face with which it is in contact with the flap 5, said face preferably being the posterior lateral face of the flap 5. It therefore does not substantially allow liquids, soils or microbes to pass into inaccessible areas or, for example, in the zone situated between the fastening system 2 and the toilet water tank. The whole bezel / fixing systems / flap / hinges is preferably monobloc.

The polymer material of the first hinge 4 and, optionally, the second hinge 6 is preferably configured to provide a "downhill damping" function. The viscoelastic properties in elongation and compression of the polymer material hinges thus allow to slow down the speed of the bezel 1 and the flap 5 during their lowering.

The connection between the various elements of the device for toilets, in particular the hinges 4 and 6, the telescope 1, the flap 5, the first fastening system 2 and / or the second fastening system 2bis, is made in such a way that there is a very good adhesion between these different elements substantially excluding any void or gap. Said connection can be done by gluing or by association of a bonding and a mechanical connection. Preferably, an overmolding of the first hinge 4 on the bezel 1 and the first fastening system 2 and an overmoulding of the second hinge 6 on the flap 5 and the second fastening system 2bis allows the connection of these elements by chemical compatibility. The voids or interstices between the different elements are thus limited or even eliminated.

According to an advantageous embodiment, the first hinge 4 extends under a part of the fastening system 2 to form a seal 12 around the fastening system 2, said seal 12 being positioned between the fastening system 2 and the tank 3 and advantageously on the outer periphery of the lower face of the first fastening system 2. The seal 12 can possibly be independent of the first hinge 4. The seal 12 is preferably made of a flexible polymeric material (30 to 90 Shore A). The seal 12 is an integral part of the one-piece device in that it is associated with the device by gluing, injection or overmolding. The seal 12 is configured to ensure good liquid tightness between the fastening system 2 and the tank 3. This is particularly advantageous especially for splashing liquid coming from the upper face or the lateral faces of the fastening system 2 and / or of the tank 3. Furthermore, the seal 12 can significantly reduce slippage of the toilet device on the tank 3 and thus ensure its retention in place. This better hold also allows less clamping when fixing the device on the tank 3.

According to a preferred embodiment, the bezel 1, the first fastening system 2, the flap 5 and the second fastening system 2bis are made of polypropylene (PP). The PP may be reinforced by mineral fillers such as talc or calcium carbonate (CaCOa) in order to obtain the mechanical or surface properties adapted to the final product.

Advantageously, the second hinge 6 extends under a portion of the second fastening system 2a between said second fastening system 2bis and the first fastening system 2 to form a seal 18. The seal 18 may optionally be independent of the second hinge 6. The seal 18 is preferably on the outer periphery of the lower face of the second fastening system 2a. The seal 18 is preferably made of flexible polymer material (30 to 90 Shore A). The seal 18 is an integral part of the device in that it is associated with the second fastening system 2bis by gluing, injection or overmolding. The seal 18 is configured to ensure a good seal to liquids, dirt or microbes between the first and second fastening systems 2 and 2bis. Furthermore, the seal 18 makes it possible to greatly reduce the sliding of the first and second fastening systems 2 and 2bis between them and thus ensure their retention in place. This better maintenance can also allow a less significant tightening when fixing the fastening systems 2 and 2bis on the tank 3. PT / F 2013/000320

The two arms act as a spring in tension and their two ends are connected to the bezel 1 and / or the flap 5 on the one hand and the first fastening system 2 and / or the second fastening system 2bis on the other part by secondary joints. According to such an embodiment, the bezel 1 and / or the flap 5 can remain in the raised position or in the folded position without the need to apply any constraint to them. When a constraint is applied to them to raise or lower them, it suffices that the stress is sufficient to exceed a position of equilibrium (advantageously about 45 ° with respect to the main plane of the upper face 19 of the vessel 3) for that the arms play their role as a spring in traction and alone induce the folding or raising of the bezel 1 and / or the flap 5 depending on the position of the bezel 1 and / or the flap 5 by relative to the equilibrium position.
